Description

  The present invention relates to a hinge for holding a door in an openable and closable manner on a frame.

  Traditionally, hinges and pivot hinges have been used to attach doors to furniture and other frames so that they can be opened and closed. It is said that the condition is the best. However, in the case of hanging out, the shaft core part is always exposed outside the door, and it is said that the design of storage furniture is not good. In addition, in storage furniture and the like, there are many cases in which a door is covered on the front surface of the frame, and it is difficult to deal with ordinary hinges as they are.

  Therefore, a configuration in which the shaft center 13 is disposed within the thickness of the door 41 is conceivable. However, in the case where the shaft center 13 is disposed without being exposed on the door front surface 17 or the side surface, as shown in FIG. The door inner case 16 is engraved under the condition that a certain thickness is left on the front surface 17 and the side surface, the door side case 1 having the axial insertion hole 10 is disposed therein, and the blade member having the axial insertion hole 10 is also provided. 3 is inserted into the door-side case 1 and the shaft center 13 is passed through both of them. The blade member 3 is mounted on the frame side plate inner surface 18 and the door 41 is held by the frame body 42. At this time, only a slight gap is set between the door inner surface 16 and the frame side plate front surface 19. As shown in FIG. 14 (b), the inner surface end corner 20 of the door immediately follows the opening operation and comes into contact with the front surface 19 of the frame body side plate 19, and it is difficult to adapt the cover. In view of this, a slide hinge that can be opened and closed with the door inner surface 16 covering the frame body side plate front surface 19 is most commonly used. In the case of wall storage, etc., with a plurality of doors 41 arranged on the same surface. It is said that the body side plate front surface 19 is hidden by the door 41 and the design is very good.

  Regarding the slide hinge, the link mechanism as the basic structure is already known, and as an improved product thereof, Japanese Patent Laid-Open No. 6-34665, Japanese Patent Laid-Open No. 2000-17931, or Japanese Patent Laid-Open No. 2002-2002. Many reports have been made in 138748, JP-A 2005-194747, JP-A 2012-12823, and the like. In addition, in the above-mentioned Japanese Patent Laid-Open No. 6-34665, there is room for improvement as a problem of all the slide hinges, and the slide hinge itself protrudes inside the storage space. In the case of a closet, the point to be caught when putting in and out clothes is mentioned as an improvement point. Japanese Patent Application Laid-Open No. 6-34665 is an improvement for avoiding further protrusion of the screws for adjusting the installation, and does not touch on reducing the protrusion of the slide hinge itself. In other words, in the present situation, it is assumed that the protrusion inside the storage space of the current level is unavoidable in order to obtain a unique operation with the slide hinge link mechanism.

  In addition, as described in Japanese Patent Application Laid-Open Nos. 2000-17931 and 2005-194747, the conventional slide hinge needs to finish a large number of parts with high accuracy, and the assembly thereof is also strict. Required. Therefore, there is a demand for a new configuration that can be realized by a slightly easier assembly operation with a small number of parts.

In addition, the slide hinge is a link part mechanism that uses springiness, and it also has a mechanism that works when the door is less than a predetermined angle when it is closed. As a result, the door can be completely closed. . And in normal storage furniture doors, two slide hinges are used at the top and bottom, but since this closing force is a uniform load for one slide hinge, the size of the door is actually used. The closing condition changes depending on the weight. In other words, the door is narrow and light, and the closing force works very strongly, and the closing condition is such that it collides with the bang. On the other hand, the wide and heavy door does not have enough closing force to close completely. A phenomenon occurs. However, the phenomenon that the door does not close completely has a high degree of importance and causes a malfunction, so the spring force is set to be strong so that the majority of doors can be closed. Is employed, and the configuration is reported in Japanese Patent Application Laid-Open Nos. 2002-138748 and 2012-12823.
JP-A-6-34665 JP 2000-17931 A JP 2002-138748 A JP 2005-194747 A JP 2012-12823 A

  The present invention has been made in order to solve the above-mentioned problems, and enables the door to be opened and closed with a new trajectory so that the closing force at the final closing stage corresponding to the size and weight of the door can be obtained. Furthermore, it is to provide a hinge that can be formed as thin as possible with a ledge disposed inside the storage space.

  In the present invention, the following technical means are provided to achieve the above object. First, a door-side case having a horizontal plane in which a long hole is formed, a slide member having a horizontal plane in which an arc hole is formed around the axial insertion hole and the axial insertion hole, an interlocking pin insertion hole and an axial insertion A blade member having a horizontal surface in which holes are formed and an attachment surface is provided. Then, in a state where the horizontal surfaces of the blade member and the slide member are overlapped with each other, the shaft centers are inserted through the shaft center insertion holes of the blade member and the slide member so that both are rotatably connected. Next, in the state where the sliding member is restricted to allow only linear movement in the door side case, the horizontal surfaces of the both are placed on top of each other, and the interlocking pin is passed through the long hole of the door side case and the arc hole of the sliding member simultaneously. In the state, it inserts in the interlocking pin insertion hole of a blade member, and assembles a door side case, a slide member, and a blade member.

  In addition, since the above-described horizontal planes are not stable with a single configuration each one, two horizontal planes having long holes are provided in parallel in the door side case, and the slide member is formed as a substantially rectangular parallelepiped recess therebetween. 2 is formed in a substantially box shape having two horizontal planes having an axial hole and an arc hole centered on the axial hole, and the blade member also has an interlocking pin insertion hole and an axial insertion hole. It is preferable that the horizontal planes are connected to each other in a substantially U-shape and further provided with a vertical mounting surface. Then, two substantially U-shaped horizontal surfaces of the blade member are inserted into the slide member, and the two horizontal surfaces are overlapped with each other and connected with an axis, and the substantially box-shaped slide member in this state is connected. Furthermore, it is fitted in the recessed part of the door side case so that it can move only in one direction, and with the three horizontal surfaces superimposed, the interlocking pin is inserted through the long hole and the circular arc hole and inserted into the interlocking pin insertion hole. A hinge is constructed by assembling the door side case, the slide member, and the blade member.

  As a means to attach the hinge to the door and the frame body, the door side case is formed with a mounting surface, and the door side is engraved on the door side so that the long holes in the horizontal plane are arranged within the thickness of the door. Install the case, provide a vertical mounting surface continuously from the substantially U-shaped portion of the blade member, and mount the blade member mounting surface on the near side of the inner surface of the frame body side plate so that the door is framed Retained. At this time, the door inner surface is arranged close to the front part of the frame side plate with a certain gap in the closed state.

  When the door is opened from the closed state, the interlocking pin is inserted into the arc hole of the slide member and the long hole of the door side case at the same time, so that the door side case is gradually moved forward with respect to the slide member up to a predetermined angle range. Since the door is fixed to the door side case, the door inner end corner is rotated without coming into contact with the frame body side plate front surface. After the predetermined angle range, the door side case returns to the back direction with respect to the slide member. In addition, since the maximum opening angle of the door can be set by the opening angle with respect to the axial insertion hole of the arc hole of the slide member, the door front end corner is at the position just before contacting the front surface of the frame side plate at the maximum opening. The opening angle of the arc hole of the slide member may be set at an arbitrary angle of 90 degrees or more.

  Moreover, since the closing force which the conventional slide hinge itself has is a necessary condition, the hinge of the present invention is assumed to have the same function. Therefore, a rectangular space is expanded in the side portion of the substantially rectangular parallelepiped recess portion of the door side case, the first inclined surface is provided on the slide member, and the spring receiver having the second inclined surface is attached to the first inclined surface of the slide member. It arrange | positions so that a surface and the 2nd inclined surface of a spring receiver may face each other, A spring member is inserted between rectangular space edge parts and a receiving member, and it is comprised so that it may always urge in the direction where both inclined surfaces may overlap more. . Then, when opening the door from the closed state, the first inclined surface of the slide member receives the spring support because the door side case is opened while gradually pushing the door side case toward the slide member up to a predetermined angle range. When the door is left as it is at an opening angle that is less than the predetermined angle range, the force to try to return the door side case to the back direction by the biasing force of the spring member Occurs, resulting in the action of closing the door

  Next, when the door is further opened beyond the predetermined angle range, the interlocking pin is inserted into the arc hole of the slide member and the long hole of the door side case at the same time. The side case returns to the back direction, and in the same direction as the force to return the door side case to the back direction by the biasing force of the spring member, as a result, if the door is left at a position exceeding the predetermined angle range, The operation to open the door to the maximum opening angle is obtained. As a result, when opening the door, the door is closed when the opening angle is smaller than the predetermined angle range in the middle, and when the opening angle is large, the door is opened until the end. An operation of allocating and energizing the opening side and the closing side across the angle range is obtained. It is also possible to arbitrarily set the predetermined angle range by changing the shape and angle of the long hole of the door side case.

  In addition, it is more effective if the closing force can be reduced when the door is light and can be increased when the door is heavy. Therefore, a spring force adjusting member is provided on the opposite side of the spring receiver sandwiching the spring member in the rectangular space of the door side case, and the spring force adjusting member is moved from the door inner surface side with the door opened, thereby It is even better to have operating means that can increase or decrease the biasing force of the member. As its means, two adjusting members having inclined surfaces are arranged on the opposite side to the spring receiver sandwiching the spring member in the rectangular space of the door side case with the inclined surfaces facing each other. One adjustment member is provided with a female thread part so that the spring force adjustment screw is screwed into the female thread part so that the head of the screw faces the inner surface of the door and rotates idly with respect to the door side case. It is preferable that the urging force can be adjusted by arranging and turning the spring force adjusting screw to move the other spring force adjusting member in the lateral direction and pushing the spring member. Furthermore, as another means, an eccentric cam having an operation part integrated with a cross bit compatible with a driver is provided, and the operation part is arranged in the rectangular space of the door side case with the operation part arranged on the inner surface of the door, A configuration in which the biasing force can be adjusted by pushing the spring member with the side surface of the eccentric cam together with the operation of rotating the operation portion.

  It is also important to secure a wider storage space for furniture and the like, and it is desirable that the protrusion is as small as possible when a hinge or the like is attached to the inner surface of the frame side plate. Therefore, by placing the door-side case engraved within the thickness of the door, opening and closing the door inside it, and setting the mounting surface of the blade member in a vertical plate shape, storage space It is possible to reduce the dimension protruding inward.

  In addition, a means for installing and adjusting the position of the door in the front, rear, left, right, up and down with respect to the frame after construction is also necessary. Therefore, an additional frame side base member is provided, an eccentric cam for front and rear adjustment is arranged on the frame side base member and engaged with the mounting surface of the blade member, and a left and right adjustment screw is provided to the frame side base. By adopting a substantially seesaw operation that changes the angle of the blade member mounting surface around the fulcrum, the protrusion in the storage space has a very thin shape and can be adjusted in the left and right and front and rear directions. Become. Further, in the vertical adjustment, a configuration is simple in which a long hole in the vertical direction is provided on the mounting surface of the door-side case, and the vertical position is re-fixed after pushing and pulling after loosening the mounting screw.

  By opening the door-side case with a long hole, a slide member having an axial insertion hole and an arc hole, and a blade member having an interlocking pin insertion hole and an axial insertion hole with the axial center and the interlocking pin, the door is opened when opened. A trajectory is obtained in which the inner surface side end corner rotates without contacting the front surface of the frame body side plate, and the door can be opened and closed in the cover. Moreover, since the opening / closing mechanism part itself can be implemented in the embedded range in a state where the door-side case is engraved in the thickness of the door, the inside of the storage space for furniture or the like can be used effectively.

  Using the movement operation of the door side case in only one direction with respect to the slide member during the opening and closing operation, a rectangular space is expanded in the door side case, and a slide member provided with a first inclined surface therein, When the spring member and the spring member having the second inclined surface are inserted and the spring member is always biased in a direction in which both inclined surfaces more overlap, when the door is opened from the closed state, the first slide member The inclined surface pushes the second inclined surface of the spring receiver and compresses the spring member.If the door is left as it is at an opening angle less than the predetermined angle range, the door side case is moved in the back direction by the biasing force of the spring member. The operation of closing the door by the force of returning can be obtained.

When the door is further opened beyond the predetermined angle range, the door side case returns to the back direction with respect to the slide member, and the same direction as the force to return the door side case to the back direction by the biasing force of the spring member As a result, if the door is left at a position that exceeds the specified angle range, the door can be opened to the maximum opening angle as it is, and the door will not be closed without permission. Can be retained.

Within the rectangular space of the door side case, a spring force adjusting member is provided on the opposite side of the spring receiver with the spring member interposed therebetween, and the spring force adjusting member is moved and adjusted from the inner surface side of the door with the door open, Providing operation means that can increase or decrease the urging force provides the optimal closing force at the final stage of closing, which can arbitrarily correspond to the size and weight of the door, preventing sudden closing of the door and malfunctions that cannot be fully closed. It becomes possible to do. As a result, it is assumed that the shock absorbing damper used in the conventional slide hinge is not necessary.

In addition, when the installation adjustment mechanism is provided, a frame-side base member is additionally provided, an eccentric cam for front-rear adjustment is arranged on the frame-side base member and engaged with the attachment surface of the blade member, and a left-right adjustment screw is installed. When the mounting surface of the blade member is installed on the frame side base by a substantially seesaw operation that changes the angle around the fulcrum, a thin flat adjustment mechanism part protrudes inside the storage space, and it moves in the left and right and front and rear directions. Adjustment is possible. It is also easy to have a vertical adjustment mechanism that has a long hole in the vertical direction on the mounting surface of the door-side case, and then pushes and pulls it after loosening the mounting screw and re-fixes it after adjusting the vertical position. It is. As a result, the dimension protruding into the storage space can be greatly reduced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a basic form of the hinge of the present invention having only a door opening / closing mechanism portion, FIG. 2 is a top view of a door-side case in the basic form, and FIG. 3 is a top view of a slide member. FIG. 4 shows a top view of the blade member. First, as shown in FIGS. 1 and 2, the door-side case 1 has a substantially rectangular parallelepiped recessed portion 6 having a shape in which two parallel horizontal surfaces 5 each having a long hole 4 are connected to a bottom surface 7 and both side surfaces. The attachment surface 8 is provided above and below. Further, the long hole 4 has an inclination at a certain angle as shown in FIG. As shown in FIGS. 1 and 3, the slide member 2 is also formed in a substantially box shape having two horizontal planes 5 having an axial insertion hole 10 and an arc hole 11 centered on the axial insertion hole 10. Has been. At this time, when the slide member 2 is inserted into the recessed portion 6 of the door-side case 1, it is preferable to set both dimensions so that they can move only in one direction without rattling.

  As shown in FIGS. 1 and 4, the blade member 3 also has a mounting surface 8 in a direction perpendicular to a portion where two horizontal surfaces each having an interlocking pin insertion hole 12 and an axial center insertion hole 10 are connected in a substantially U shape. The substantially U-shaped portion of the blade member 3 is inserted into the slide member 2, and the two are horizontally connected to each other at the axis 13 in a state where two horizontal surfaces 5 are superposed on each other. Then, the substantially box-shaped slide member 2 in the connected state is further fitted into the recessed portion 6 of the substantially rectangular parallelepiped of the door-side case 1, and two horizontal surfaces 5 are overlapped on the top and bottom, and two from the top and bottom. The interlocking pin 14 is inserted into the interlocking pin insertion hole 12 of the blade member 3 in a state where the interlocking pin 14 is passed through the long hole 4 of the door side case 1 and the arc hole 10 of the slide member 2, and the door side case 1, the slide member 2 and the blade member. 3 is assembled to form a hinge. At this time, the interlocking pin 14 may be a roll pin or the like of a spring suitable for press-fitting. However, as shown in FIG. 1, one end of the interlocking pin 14 is formed as a male screw part, and the interlocking pin insertion hole 12 of the blade member 3 is formed as a female screw. If it forms as a part, fixation of interlocking pin 14 will be reliable and easy.

  FIG. 5 is a top view of a state in which the hinge is attached to a box-shaped storage member. First, the door 41 is hung on the two sides so that both the recessed portion 6 and the attachment surface 8 of the door-side case 1 are embedded. The mounting surface 8 of the door-side case 1 is fixed to the door inner surface 16 with mounting screws 15 such as wood screws. The vertical attachment surface 8 of the blade member 3 is fixed to the front side of the inner surface 18 of the frame body side plate 18 with the attachment screws 15 such as wood screws, and the door 41 is attached to the frame body 42. At this time, in a state where the door inner surface 16 is covered with the frame body side plate front surface 19, it is generally accommodated so as to be closely arranged with a small gap. Further, in explaining the opening / closing operation of the door 41 from this state, as shown in FIG. 5, as shown in FIG. The opposite reverse side is expressed as the door inner surface 16, the corner position of the door 41 is expressed as the door inner surface end corner 20 and the door front end corner 21, and the direction is the door front 17 side of the entire storage member. The front direction and the opposite side of the storage member are described as the back direction. Further, the notation of each part of the frame body 42 is also expressed as a frame body side plate inner surface 18 and a frame body side plate front surface 19 as shown in FIG.

  FIG. 6 is a trajectory diagram in which the positions where the door 41 is opened every 10 degrees from the closed state are continuously described. In order to make the positional relationship of the slide member 2 relative to the door-side case 1 clear, The position of the bottom surface 7 and the position of the front side 9 of the slide member 2 are mainly clearly described. First, FIG. 6A shows a state in which the door 41 is completely closed, and the interlocking pin 14 penetrates through the front end portion of the long hole 4 of the door side case 1 and the arc hole 11 of the slide member 2 in the overlapped state. And is completely fitted with the front side 9 of the slide member 2 in contact with the bottom surface 7 of the recessed portion 6 of the door-side case 1. When the door 41 is opened from the closed state shown in FIG. 6A, the interlock pin 14 is inserted into the arc hole 11 of the slide member 2 and the long hole 4 of the door side case 1 at the same time. The interlocking pin 14 tries to move along the hole 11. At this time, the arc hole 11 of the slide member 2 and the long hole 4 of the door side case 1 are in an intersecting state, and since the intersection angle is relatively large, the operation of pushing the long hole 4 of the door side case 1 forward. become. Further, since the slide member 2 can move only in the direction of the door inner surface 16 which is perpendicular to the door 41 with respect to the recessed portion 6 of the door side case 1, as a result, as shown in FIG. While the recessed portion 6 of the door-side case 1 slides, the door 41 rotates while taking the door 41 forward. That is, a gap is generated between the bottom surface 7 of the door-side case 1 and the front side 9 of the slide member 2, and the dimension of the gap is set to the B dimension in the state of FIG.

  The operation of bringing the door 41 forward along with this opening is from FIG. 6C with the door 41 opened 20 degrees to FIG. 6E opening FIG. 6D with 30 degrees opened and FIG. 6D opened. Therefore, the gap between the bottom surface 7 of the door-side case 1 and the front side 9 of the slide member 2 gradually increases as B <C <D <E. This operation is effective in solving the problem that the door inner surface end corner 20 abuts against the frame side plate front surface 19 as shown in FIG. 14 in the initial stage of opening the door 41. Here, FIG. 14 shows the door 41 and the frame body 42 under the same conditions, and the position of the shaft center 13 also shows a single-axis rotation trajectory from the same state as FIG. 6, and in the closed state shown in FIG. 6 (a), but at the position of 20 to 30 degrees when the door is opened, the door inner end corner 20 abuts against the frame side plate front face 19 as shown in FIG. It will be in a state that can not be opened.

  However, in FIG. 6, the door 41 itself rotates together with the door-side case 1 while being opened, and rotates while being opened, so that the position of the door inner surface 16 in the closed state in FIG. Since the door 41 itself is gradually taken out as the door inner surface end corner 20 approaches the frame body side plate front surface 19, the door inner surface end corner is until the 40 ° open position in FIG. 6 (e). A trajectory 20 that does not substantially approach the frame body side plate front surface 19 is obtained.

  The range from FIG. 6 (e) at the 40 ° open position to FIG. 6 (g) at the 50 ° open position through FIG. 6 (g) is the arc hole 11 of the slide member 2 and the door side case 1. The crossing angle with the long hole 4 is very small, and the amount of the door case 1 taken out with respect to the opening angle of the door 41 is hardly changed. Therefore, the clearance dimension between the bottom surface 7 of the door-side case 1 and the front side 9 of the slide member 2 is approximately E≈F≈G. Here, the range from FIG. 6E to FIG. 6G is defined as a predetermined angle range. In addition, since the door inner surface end corner 20 does not approach the frame body side plate front surface 19 at the stage of FIG. 6E, the door inner surface end corner 20 slightly approaches the frame body side plate front surface 19 in the subsequent opening operation. Although it becomes a locus, since it operates sufficiently within the gap range in the initial set-up, there is no problem in opening the door 41 in FIG.

  Then, from FIG. 6 (g), which is the 60 ° open position, the intersection angle between the arc hole 11 of the slide member 2 and the long hole 4 of the door side case 1 gradually increases in the opposite direction. The gap dimension between the bottom surface 7 of the side case 1 and the front side 9 of the slide member 2 is conversely reduced, so that G> H> I> J when opening 90 degrees from the 70 degree opening position and opening 90 degrees. And in the 100 degree | times open position shown in FIG.6 (k), the clearance gap K of the bottom face 7 of the door side case 1 and the near side 9 of the slide member 2 becomes quite small. In addition, since the door front end corner 21 moves to the position just before the frame body side plate front surface 19 abuts at the 100 degree open position, if the opening angle of the arc hole 11 of the slide member 2 is set at 100 degrees, The opening of the door 41 can be stopped at this position. 6 (g) to 6 (k), the door inner surface end corner 20 does not contact the frame body side plate front surface 19.

  The configuration of rotating the door 41 while taking it forward is based on the setting shown in FIG. 6, but the extent of the take-out and the position for each opening angle can be arbitrarily changed. As the means, a method of changing the inclination degree of the long hole 4 of the door side case 1 or the shape of the long hole 4 itself is not a linear shape, but a large arc shape with a reverse R to the arc hole 11 of the slide member 2. Various means are possible, such as a method of making a straight line portion and a large arc portion continuous. In addition, since the position of the axis 13 in the recessed portion 6 in the closed state and the distance and arrangement of the arc hole 11 with respect to the position also affect the opening locus, selecting various elements and selecting the most effective opening / closing locus good.

  Next, a closing mechanism that is another necessary condition will be described, and then a configuration in which the position of the door 41 with respect to the frame body 42 that is another necessary condition is installed and adjusted after construction will be described. FIG. 7 is an exploded perspective view of a configuration in which a closing mechanism and a building adjustment mechanism are added to the basic form shown in FIG. FIG. 8 is a top view of a configuration in which only a closing mechanism is added to the basic form. First, as shown in FIGS. 7 and 8, the first inclined surface 22 is provided on the slide member 2. Then, as shown in FIG. 8, the rectangular space 25 is extended to the lateral side portion of the substantially rectangular parallelepiped recessed portion 6 of the door side case 1, and the spring receiver 23 having the second inclined surface 24 is combined with the spring member 26 into the rectangular space 25. The first inclined surface 22 of the slide member 2 and the second inclined surface 24 of the spring receiver 23 are arranged so as to face each other. At this time, the spring member 26 is set so as to be urged in a direction in which both inclined surfaces overlap more. Therefore, the second inclined surface 24 of the spring receiver 23 is always pressed against the first inclined surface 22 of the slide member 2 by the spring member 26.

  FIG. 9 is a locus diagram when the door 41 is opened from the state of FIG. 8, and the opening / closing mechanism portion is the same as the operation shown in FIG. 6, so the bottom surface 7 of the door side case 1 and the front side of the slide member 2 are the same. The gap dimension with 9 is B <C <D <E from 0 degrees to 40 degrees in FIG. 6 and the gap dimension increases, and until the subsequent 60 degrees release, E≈F≈G and the gap dimension is almost constant. Then, G> H> I> J and the gap size become smaller again until 100 degrees after that. Therefore, in the initial stage of opening, the door-side case 1 moves in the forward direction while the first inclined surface 22 of the slide member 2 pushes the second inclined surface 24 of the spring receiver 23, and the direction of the force is changed by both inclined surfaces. As a result, the spring member is compressed. FIG. 9B shows the 40-degree opening stage, and when the door 41 is left as it is with the spring member 26 being greatly compressed, the slide member 2 is also moved by the force of the spring member 26 returning. The force for returning to the closed state is activated, that is, the door 41 can be closed.

  As described above, from the 40 degree opening shown in FIG. 9B to the 60 degree opening vicinity shown in FIG. 9C, the gap dimension between the bottom surface 7 of the door-side case 1 and the front side 9 of the slide member 2 is almost the same. Since the predetermined angle range is constant, if the door 41 is left in the predetermined angle range, it is assumed that the door 41 stops at the same position. When the door 41 is further opened beyond the predetermined angle range, the gap dimension between the bottom surface 7 of the door-side case 1 and the front side 9 of the slide member 2 becomes smaller. The side case 1 returns to the back direction, and the same direction as the force to return the slide member 2 to the back direction by the biasing force of the spring member 26. If the door 41 is left as it is, it is shown in FIG. 9 (d). In this way, the door 41 is opened to the maximum angle as it is.

  Therefore, as a whole opening / closing operation, when the door 41 is opened from the closed state, the door 41 is closed when the opening angle is smaller than the predetermined angle range in the middle, and when the opening angle is large, the door 41 is opened to the end as it is. In the closing operation, the opposite operation is performed, and an operation of allocating and energizing the opening side and the closing side across a predetermined angle range is obtained.

  Here, in the conventional slide hinge, the closing force of the door 41 is constant. Therefore, in a light door with a narrow frontage, the spring force tends to be over and it closes easily. If the door is wide and heavy, there will be a phenomenon that the spring force will not be enough to close. Therefore, a configuration is often used in which a strong spring force is set and when the force is too strong, a damper is used to absorb the force immediately before closing. However, if the closing force itself can be adjusted, it is assumed that it is not necessary to use a damper, and a more effective configuration is desired.

  Therefore, a configuration is provided in which the spring force can be adjusted on the side opposite to the spring receiver 23 sandwiching the spring member 26 in the rectangular space 25 of the door side case 1, and the spring member 26 is opened from the door inner surface 16 side with the door 41 opened. It is preferable to have an operation means that can increase or decrease the urging force. FIG. 10 is a top view of an example of the means, and FIG. 7 shows the same configuration.
