Description

The present invention relates to a handle apparatus described in the premise part (so-called part; preamble part) of claim 1 .

  A handle device is known in which the handle is formed as a substantially U-shaped curved member. The handle includes an upper handle portion and a lower handle portion which are shifted from each other in the height direction. Both handle portions extend parallel to each other. The handle is connected to the fixed plate via a universal bearing (rocker pivot). The universal bearing is provided with a spring element. The spring element is adjusted to hold the handle from falling in any swing position. Since this handle is mainly for people with disabilities or needing care, it is often the case for these people to swing the handle upward from a horizontal use position to a stop position (non-use position). It is difficult. This is because these people always have to overcome the spring force when swinging upward. Furthermore, the patient cannot fully support the handle because both parts of the handle are parallel to each other.

  The technical problem underlying the present invention is to form the handle device described at the beginning so that a simple and nevertheless reliable operation is ensured.

This object is achieved in accordance with the present invention in a handle device described in the introduction are solved by the features of claim 1.

  In the case of the handle device according to the first aspect of the present invention, the holding force acting on the handle when swinging is changed by the tightening device. The tightening element is adjusted so that the holding force applied by the spring element is reduced when the handle is swung upward from the use position to the stop position. Thereby, a person with a large disability or a person who needs care can swing the handle upward without any problem. Since the clamping element moves relative to the spring element when the handle is swung, the spring force can be easily increased or decreased according to the transition direction.

  The handle device according to claim 1 is any device including a swing member that is held at all swing positions by a holding force. One example is a folding shower seat. The seat portion can swing from a horizontal use position upward to a stop position. Since the seat part is held in all swinging positions like the handle by the holding force produced by the spring element, the seat part cannot fall.

  In the case of the handle device according to claim 7, the lower handle part is no longer arranged parallel to the upper handle part and forms an acute angle. Since two handle devices are generally arranged next to the toilet bowl, for example, when the lower handle portion is arranged at an acute angle with respect to the upper handle portion, the user's exercise space between the two handle devices becomes the handle. Can be expanded toward the free end. Thereby, an optimum degree of freedom of movement for the user is ensured between the handles of the handle device swung downward.

  In the case of the handle device according to claim 10, the adapter plate is attached in advance, for example, when the wall is painted or when the wall is first constructed. And since there is no need to fix the entire handle device with the handle, there is no risk of damage to the handle device at this stage of new construction or repair. When the work on the wall is finished, the handle device can be fixed to the adapter plate attached in advance by the fixing plate. The use of the adapter plate is particularly advantageous in that the adapter plate can be attached as a connecting member of the handle device in a plurality of rooms or rooms such as nursing homes, hospitals and the like. There is no need to have a handle in every room. A handle can be brought and connected by a fixed plate to the adapter plate provided there in each room. Since a plurality of adapter plates can be provided at different locations in one room, the handle can be quickly connected to the required location each time.

Other features of the invention will be apparent from the other claims, specification and drawings.
The present invention will be described in detail based on some embodiments shown in the drawings.

  The handle device described below is used especially for persons with disabilities or those in need of care in hospitals, nursing homes, social welfare facilities and the like. The handle device has a support handle. Next, the support handle will be described in detail with reference to FIGS. The support handle is connected to the fixed plate 2 via the universal bearing 1. The support handle can be fixed to a wall or the like by the fixing plate. The fixing plate 2 includes a hole 3 for allowing a screw, a bolt, or the like to pass therethrough. The fixing plate 2 can be attached to the wall with these screws, bolts and the like. The support handle has an upper leg 4 in the use position. The upper leg portion extends straight from the universal bearing 1 and is formed by a part of a tube bent into a substantially U shape. The leg 4 is the end opposite to the rocking bearing 1 and is connected to the lower leg 6 at the use position via the curved portion 5. The leg 6 is a part of a curved tube, like the curved portion 5. The leg 6 extends over about two-thirds the length of the leg 4 and is connected to the end section 8 via an inclined section 7. Both the leg portions 4 and 6 are shifted from each other in the vertical direction and the horizontal direction. Only the end section 8 of the lower leg 6 is in the same vertical plane as the upper leg 4. As can be seen from FIG. 1, when the support handle is viewed from above, the lower leg 6 forms a small acute angle α with respect to the upper leg 4. This angle is, for example, about 3 to 6 °. Therefore, when viewed from above, the legs 4 and 6 extend from the curved portion 5. The angle α is measured by projecting onto a horizontal plane.

  The legs 4 and 6 do not need to be connected to each other through the curved portion. The connecting part may for example extend straight. Furthermore, as shown to FIGS. 9-14, the leg parts 4 and 6 can be mutually connected via the spacer which is distant from the free end of the upper leg part.

  As can be seen from FIG. 2, the leg 6 similarly forms an acute angle β with respect to the upper leg 4 when viewed in the horizontal direction. Thereby, the leg portion 6 is disposed obliquely downward from the curved portion 5 toward the fixed plate 2. Since the leg 6 of the support handle extends obliquely and vertically with respect to the leg 4, an important advantage for the user of the support handle arises. This advantage will be described with reference to FIGS. Figures 5 and 6 show typical applications of the support handle. The support handles are on both sides of the toilet bowl 9 so that they can be easily gripped by the occasional user. Both supporting handles are fixed to the wall 10 by the fixing plate 2 so that the lower leg 6 protrudes from the attached upper leg 4 toward the supporting handles. Based on the acute angle α that the lower leg 6 makes with the upper leg 4 when viewed in the vertical direction, the width 11 of the exercise space 12 in the range between the support handles for the user of the toilet seat 9 is Expanding. Therefore, when the user stands up from the toilet seat, the support handle extends in the horizontal direction, but does not adversely affect or disturb the user. Further, since the leg 6 is formed to be inclined upward toward the curved portion 5 at an angle β, the patient securely grasps with his hand when standing up from the toilet seat 9 or when sitting down on the toilet seat. Can. Since the lower leg 6 extends upwardly toward the curved portion 5 as seen from the patient, the patient can reliably support and hold the lower leg 6 with both hands. Since the upper leg 4 is arranged so as to be shifted outward with respect to the lower leg 6 in the vertical direction, when the user grasps the lower leg 6 with his hand, the upper arm 4 is placed on the upper leg 4 by the forearm. Can be additionally supported. The distance between the legs 4 and 6 in the height direction is selected so that the patient can optimally support the arm.

  The free end of the upper leg 4 is supported by an arcuate swing member 13. This arcuate rocking member is pivotally supported by the fixed plate 2 by a universal bearing 1. The end section 8 of the lower leg 6 is fixed to the lower end 14 of the arcuate swing member 13 (FIG. 1). A buffer member 82 is fixed to the side of the arcuate swing member 13 opposite to the leg portion 6. This buffer member is in contact with the fixed plate 2 in the horizontal use position of the support handle. The support handle can swing upwards around the axis of the universal bearing 1 from a horizontal use position to a stop position indicated by a dotted line in FIG.

  The support handle is held so as not to fall in a vertical stop position. In all intermediate positions between the stop position and the use position, the support handle is held so as not to swing downward. The support handle can be swung to the respective position by the user himself / herself. An apparatus provided for this purpose will be described with reference to FIGS. This device is suitable for all kinds of folding elements. That is, it is suitable not only for the support handle but also for a folding shower seat, for example. For simplicity, FIG. 8 shows the same support handle as in FIGS.

  Two bearings 15 and 16 are fixed to the fixed plate 2 at intervals. The bearings are formed identically. A bearing ring 17 of the arcuate swing member 13 is engaged between the bearings 15 and 16. A bush 18 passes through the bearing ring 17. The bush contacts the inner wall of the bearing ring 17 and protrudes from the bearings 15 and 16. The bush 18 has an annular groove 19 having a V-shaped cross section on the outer surface thereof. The bearing ring 17 has a screw hole 20 passing through its wall. This screw hole accommodates a threaded pin 21. The tapered end of the threaded pin reaches into the annular groove 19 of the bush 18. Thus, the bearing ring 17 is connected to the bush 18 so as not to rotate relatively.

  Instead of the annular groove 19, a flat part or recess for the threaded pin 21 can be provided in the bush 18. The threaded pin contacts the flat or engages the recess. Thereby, the bush 18 is connected to the bearing ring 17 so as not to rotate relatively.

  The bush 18 is only slightly inserted into the bearings 15 and 16. One ring 22 and 23 is attached to the end of the bush 18 inserted into the bearings 15 and 16, respectively. Both rings 22 and 23 are provided with ribs 24 and 25 extending in the axial direction on the outer periphery. The rib engages with grooves 26 and 27 provided on the inner walls of the bearings 15 and 16. The grooves 26 and 27 extend over the axial length of the bearings 15 and 16. Since the bearings 15 and 16 are fixed to the fixed plate 2, the rings 22 and 23 are held so as not to rotate by the above-described shape meshing connection. The ring 22 protrudes from the bush 18 in the axial direction.

  The bearing ring 17 of the arcuate swing member 13 has one recess on each side surface. One annular slide disk 28, 29 is provided in each recess. The rings 22 and 23 are in contact with the slide disks 28 and 29.

  The slide disks 28 and 29 are surrounded by seal rings 30 and 31 at a distance. This seal ring is inserted into an annular groove on the side surface of the bearing ring 17. The seal ring seals the bearing ring 17 against the bearings 15 and 16.

  A washer 32 is in contact with the side of the ring 22 opposite to the slide disk 28. This washer is provided with a protrusion 33 extending in the axial direction on the outer periphery (FIG. 8). This projection of the washer 32 engages the axial groove 26 of the bearing 16. Thereby, the washer 32 is held so as not to rotate. A nut 35 faces the washer 32 at an axial interval with at least one compression spring 34 interposed therebetween. In the present embodiment, two disc springs 34 are provided between the washer 32 and the nut 35. This nut is screwed into the tapered end section 36 of the threaded pin 37. The threaded pin is screwed into the bush 18. The bush has a female thread 38 over a portion of its length. The nut 35 is held by a lock nut 39 screwed into the end section 36 of the threaded pin 37.

  The washer 32 has a projection 40 on its inner wall that protrudes beyond its thickness. This protrusion is engaged with a recess 41 extending in the axial direction provided on the outer surface of the end section 36 of the threaded pin 37.

  One covering caps 42 and 43 are inserted into the end portions of the bearings 15 and 16 which are separated from each other. Thereby, a part of the universal bearing is protected from contamination and / or from damage.

  The spring force is adjusted by the nut 35 so that the support handle is securely held at all swing positions. Both disc springs 34 press the ring 22 through the washer 32 against the slide disk 28 of the bearing ring 17 connected to the support handle. The spring force can be easily and accurately adjusted by the nut 35. Since the spring force always acts on the bearing ring 17, when the support handle is swung from the horizontal use position toward the vertical stop position, the support handle is suddenly dropped to the horizontal use position at any time. Never come back.

  When the support handle swings from the horizontal use position toward the vertical stop position, the bush 18 similarly rotates about its axis. This is because the bush is connected to the bearing ring 17 so as not to rotate relatively. The remaining portion of the universal bearing 1 is held as described above so as not to rotate. Since the threaded pin 37 is screwed into the bushing 18, when the bushing 18 rotates relative to the threaded pin 37, the threaded pin 37 is moved when the support handle swings toward the stop position. Move upwards. As a result, the amount of compression of the spring decreases, so that the more the support handle is swung upward, the more easily it can be swung. In any case, the amount of spring compression is adjusted so that the support handle is held in all swing positions. When the support handle is swung back from the upward swing position to the horizontal use position, the threaded pin 37 is moved again into the bush 18 by the rotational movement of the bush 18, so that the amount of spring compression increases. When the support handle is in the vertical stop position, the patient does not need to apply significant force to swing the support handle downward. The spring force is only increased when the support handle reaches a swing position where the patient can easily grasp and swing the support handle downward.

  The support handle is fixed to the arcuate support member 13 by two connecting members 44 and 45 (FIG. 8). The support handle is formed, for example, in the same manner as in the embodiment of FIGS. The support handle may be of other shapes as well. As shown in FIG. 7, the connecting member 44 is inserted into the leg 4 of the support handle and the bearing ring 17 of the arcuate swing member. The leg portion 4 of the support handle has a female screw 46 at its end, and a male thread section 47 of the connecting member 44 is screwed into this female screw. A portion of the connecting member 44 located in the bearing ring 17 has an annular groove 48 extending in the circumferential direction. This annular groove is formed by two conical surfaces 49, 50 which are opposed in opposite directions. The bearing ring 17 has, for example, two screw holes 51 and 52 for receiving one threaded pins 53 and 54, respectively. The conical end of the threaded pin contacts the conical surface 49 of the annular groove 48 and is separated from the other conical surface 50. The connecting member 44 is pulled into the bearing ring 17 by the threaded pins 53 and 54. Thereby, the leg portion 4 of the support handle is firmly pressed against the bearing ring 17.

  The connecting member 45 is fixed to the lower end 14 of the arcuate swing member 13 by a screw 83. The screw 83 passes through the end portion 14 and holds the cushioning material 82 on the other side of the arcuate swing member 13. The connecting member 45 includes an annular groove 84 having two conical surfaces opposed to each other in opposite directions. The connecting member 45 is provided in the leg portion 6. This leg has a threaded hole (not shown) for the threaded pin 85. This threaded pin, like the threaded pin 54 (FIG. 7), contacts one conical surface, whereby the leg 6 is fastened and fixed to the arcuate rocking member 13.

  In order to be able to easily attach each support handle of the support handle device to a wall or the like, it is advantageous to first use an adapter plate which is attached to the wall. Thus, for example, when the interior or exterior is not yet done, the adapter plate can first be attached to the wall and then the wall or each room can be finished. Thereafter, the support handle is fixed to the attached adapter plate by the fixing plate 2. Next, some embodiments of the adapter plate and the related fixed plate will be described.

Adapter plate 55 shown in FIG. 9 includes near its upper edge, the stepped portion 56 that extends across the width of the adapter plate. The fixing plate 2 of the support handle is provided with a corresponding stepped portion 57. The thickness of the upper range of the step portion 56 of the adapter plate 55 is thinner than the other ranges, but the thickness of the upper range of the step portion 57 of the fixing plate 2 is thicker than the other ranges. By means of both step portions 56 and 57, the fixing plate 2 can be mounted and fixed very easily at an exact position on the adapter plate 55 which has been mounted in advance. For this purpose, the adapter plate 55 has a screw hole 86. A screw that penetrates the fixing plate 2 is screwed into the screw hole. The screw is covered with a cushioning material 82 of the support handle at the use position of the support handle. The adapter plate 55 and the fixed plate 2 have the same contour.

  The adapter plate 58 of FIG. 10 has a raised edge 59 extending in the circumferential direction. The fixing plate 2 of the support handle is inserted in a range surrounded by the edge 59. The height of the edge 59 corresponds to the thickness of the fixed plate 2. The fixed plate does not protrude from the edge 59 in the assembled state. The adapter plate 58 and the fixing plate 2 have through holes 60 and 61 for screws or the like that connect them to each other. The adapter plate 58 has another hole 62 for a screw that secures it to the wall.

  The adapter plate 63 of FIGS. 11 and 12 has a hole 64 for a screw or the like for attaching it to the wall. The adapter plate 63 further has a keyhole-shaped through hole 65. The insertion element 66 engages with the through hole. This plug-in element is provided on the side of the fixing plate 2 opposite to the support handle. The insertion element 66 has an end portion with an enlarged diameter, and this end portion is inserted into the wide section of the keyhole-shaped through hole 65 of the adapter plate 63 as is well known. Subsequently, since the fixing plate 2 is lowered, the thin portion of the insertion element 66 reaches the narrow portion of the key hole-shaped through hole 65 of the adapter plate 63. Subsequently, a screw or the like is inserted into the hole 67 in the angular range of the fixed plate 2. This screw passes through a wide range of the keyhole-shaped through hole 65. As a result, the plug-in element 66 does not come off unexpectedly. The adapter plate 63 and the fixed plate 2 have the same contour.

  In the embodiment of FIG. 13, the adapter plate 68 has a step 69 near its upper edge. Unlike the embodiment of FIG. 9, this step portion extends not at a right angle but at an acute angle. Accordingly, the fixing plate 2 has a stepped portion 70 that similarly extends at an acute angle. The fixing plate 2 is fitted to an adapter plate 68 attached to the wall from above, and the acute angle step portion 70 is engaged with the acute angle step portion 69 of the adapter plate 68. The shape meshing connection thus obtained is performed like a dovetail joint. Subsequently, the fixing plate 2 is screwed to the adapter plate 68. The tail-like formation of the steps 69, 70 allows a very simple and precise orientation of the fixing plate 2 with respect to the adapter plate 68 mounted on the wall.

  In the case of the embodiment shown in FIG. 14, the adapter plate 71 and the fixing plate 2 have the same contour, and in order to allow the fixing plate 2 to be connected to the adapter plate 71, a screw or the like is passed through. Holes 72 and 73 are provided. The adapter plate 71 and the fixed plate 2 are joined together on a plane.

  FIG. 15 shows an adapter plate 74 formed as a thin plate piece. The upper and lower edges 75 and 76 of the adapter plate are bent at an obtuse angle. Both edges 75, 76 are bent obliquely to each other in the opposite direction by the same width and the same angle. The support handle fixing plate 2 has a recess 77. This concave portion has a side wall 78 provided obliquely at the upper edge, and the inclination angle of the side wall coincides with the inclination angle of the upper edge 75 of the adapter plate 74. The lower side wall 79 extends perpendicular to the bottom 80 of the recess 77. A screw hole (not shown) is provided in the side wall 79, and a threaded pin 81 is screwed into the screw hole. The threaded pin reaches into the recess 77 and is screwed into the recess until its conical end contacts the lower edge 76 of the adapter plate 74.

  In order to allow the fixing plate 2 to be easily fitted into the adapter plate 74, the threaded pin 81 is first rotated in the opposite direction to the screwing so that it does not protrude from the side wall 79. Thereby, the fixing plate 2 can be fitted from the front with respect to the adapter plate 74 attached in advance, and can be lowered so that the side wall 78 of the recess 77 contacts the upper edge 75 of the adapter plate 74. Subsequently, the threaded pin is screwed into the recess 77 until the conical end of the threaded pin 81 contacts the lower edge 76 of the adapter plate 74. Thereby, the fixing plate 2 is fastened and fixed to the adapter plate 74.

  Depending on the width of the adapter plate 74 or the fixing plate 2, other threaded pins can be provided in the lower side wall 79 of the recess 77.
