Description

  The present invention relates to a door opening adjustment device. More specifically, when the door is fully opened due to excessive external force due to gusts, etc., deformation of the member can be prevented, and the holding mechanism keeps the door fully open, so the holding mechanism makes an abnormal noise when opening and closing the door etc. The present invention relates to an opening adjuster such as a door that can surely prevent the occurrence.

  As shown in FIG. 8, the conventional door opening / closing adjuster includes an outer cylinder 82 and a telescopic member configured to be inserted into the outer cylinder 82 in a telescopic manner. As in the stay 81, there is known an opening degree adjuster that adjusts the opening degree of the window W by freely adjusting the length of a stay (a kind of support rod for supporting a door or the like).

  Reference numeral 84 is a hinge. The insertion member 83 is configured to be held in the fully open position with respect to the outer cylinder 82 by a holding mechanism such as a ratchet mechanism or a detent mechanism so that the window W is not inadvertently closed. As shown in FIG. 9, the fully-opening holding mechanism built in the telescopic stay 81 of FIG. It consists of a locking protrusion 62 protruding to the side. Reference numeral 60 denotes a shallow groove formed in the bottom of the outer cylinder 82, and guides the convex portion 61 formed on the lower surface of the stay stopper 56. Since the convex portion 61 is locked over the locking projection 62 formed in the shallow groove 60 when the insertion member 83 is pulled out to the maximum, the telescopic stay 81 is firmly held in the fully opened position. .

  An H-shaped slit 57 is formed in the stay stopper 56, a screw hole having a tapered seat surface is formed at the center thereof, and an adjusting screw 58 having a tapered lower surface is screwed into the screw hole. When the adjustment screw 58 is tightened, the H-shaped slit 57 is opened, both side surfaces 59 of the stay stopper 56 are projected, and are pressed against both inner side surfaces of the outer cylinder 82 to generate sliding resistance. With this resistance, the telescopic stay 81 can be held at an arbitrary length.

  Further, when the fully opened state of the window W is released, the projecting portion 61 gets over the locking projection 62 by slightly closing the window, so that the fully opened state is released.

  However, the conventional holding mechanism has a problem that the stay stopper 56 is deformed when an excessive external force is applied due to a gust of wind or the like and the telescopic stay 81 is fully opened. In addition, since the convex portion 61 on the stay insertion member 83 side moves while rubbing the inner surface of the outer cylinder 82, there is a case in which abnormal noise is generated. And when it becomes fully open, an abnormal noise is generated, which causes a problem of giving a person discomfort.

  The present invention has been made to solve such a problem, and even when an excessive external force is applied due to a gust of wind or the like, the insertion member is not deformed and a holding mechanism for holding it fully open is provided. It is an object of the present invention to provide an opening adjuster for doors and the like that can prevent abnormal noises when opening and closing the doors.

  Moreover, it is preferable that the bottom part of the said outer cylinder is provided with the braking means frictionally slid with the said insertion member.

  A switch such as a door according to claim 1 of the present invention is composed of an outer cylinder and an expansion / contraction stay having an insertion member that is inserted into the outer cylinder in a nested manner, and a stepped portion is formed inside the outer cylinder. In order to prevent the insertion member from coming out of the outer cylinder when the door or the like is fully opened, an abutting piece that abuts the stepped portion on the side edge of the rear end portion of the insertion member via a rib is provided. When the door is fully opened due to excessive external force due to gusts, etc., even if the contact piece is given a rotational moment from the step, it is absorbed by the rib. Therefore, deformation of the insertion member can be prevented.

  According to the door or other switch according to claim 2 of the present invention, it is possible to prevent the holding mechanism from generating abnormal noise when the door or the like is opened or closed by using rolling of the rotating member. Especially when it is fully open, there will be no noise, so there will be no discomfort to people.

  Next, a switch such as a door of the present invention will be described in detail below with reference to the drawings.

  FIG. 1A shows a state immediately before the contact piece of the insertion member and the stepped portion of the outer cylinder in the expansion / contraction stay constituting the switch of the present invention, and FIG. 1B shows the contact piece.

  1 to 7 includes an outer cylinder 2 and an insertion member 3 which is inserted into the outer cylinder 2 in a nested manner. A step 16 is provided inside the outer cylinder 2, a rib R is formed on the side edge of the rear end portion of the insertion member 3, and when the door D is fully opened, the insertion member 3 is connected to the outer cylinder. 2, a contact piece 15 that contacts the stepped portion 16 is integrally formed on the side edge of the rear end portion of the insertion member 2 via a rib R (see FIGS. 3 and 4). ing.

  A step 16 (see FIG. 2) is provided inside the outer cylinder 2, and when the door D is fully opened, the rear end portion of the insertion member 3 is prevented in order to prevent the insertion member 3 from coming out of the outer cylinder 2. A contact piece 15 that comes into contact with the stepped portion 16 is integrally formed on the side edge of the side edge via a triangular rib R (see FIGS. 3 and 4).

  Here, referring to FIG. 3, when the door is fully opened by an excessive external force such as a gust of wind, the contact piece 15 collides with the stepped portion 16 and rotates counterclockwise as indicated by an arrow M from the stepped portion 16. A moment is applied, and the rear end portion of the insertion member 3 receives an external force in a direction that warps in the direction of the arrow M. However, as shown in FIGS. 3 and 4, since the rib R absorbs this external force, the rear end portion of the insertion member 3 is substantially prevented from being deformed (warped in the direction of the arrow M). is there.

Moreover, the door D can be hold | maintained in a fully open state by attaching the expansion-contraction stay 1 to upper part vicinity of the door D, for example, as FIG. In Figure 6-7, the door D is D1 side is hinged to the frame member F, the bracket B ₁ represents are secured by screws to the D1 side of the frame member F. A rear end portion of the outer cylinder 2 is rotatably connected to the bracket B ₁ by a pin or the like. On the other hand, the distal end portion of the insertion member 3 is rotatably connected to the bracket B ₂ by a pin or the like. The bracket B ₂ is fixed to the vicinity of the upper portion of the door D with a screw or the like.

  As shown in FIGS. 1A and 1B, the holding mechanism includes an arm 5 having one end swingably provided with respect to a shaft 4 fixed to the rear portion of the insertion member 3, and the arm. The shaft 6 is fixed to the other end of the shaft 5 by caulking, the rotating member 7 is rotatably provided on the shaft 6, and the teeth 8 and the stopper 9 are provided on the inner side surface 2 a on the distal end side of the outer cylinder 2. It is comprised from the latching | locking part 10 which becomes. Since the height of the tooth 8 is lower than the radius of the rotating member 7, the rotating member 7 can get over the tooth 8 relatively easily.

  The arm 5 is always urged in the direction of the arrow A by, for example, a rotating spring 12, and the rotating member 7 is always in contact with the inner side surface 2a. One end of the rotary spring 12 engages with the engagement protrusion 5 a of the arm 5, while the other end (not shown) is locked inside the insertion member 3.

  In the present embodiment, an arm 5 and a rotary spring 12 that biases the arm 5 are combined as a biasing means that biases the rotating member 7 so as to abut on one inner surface 2a of the outer cylinder 2. However, the present invention is not limited to this, and various modifications, changes, and modifications obvious to those skilled in the art are included in the present invention.

  The rotating member 7 is constantly urged toward one inner side surface 2a of the outer cylinder 2 by the urging means. Therefore, since the rotating member 7 rotates when contacting the inner side surface 2a during opening and closing of the door, for example, at least when getting over the teeth 8, no abnormal noise is generated.

  The rotating member 7 is preferably made of an annular member made of a hard plastic material made of a metal material such as steel, brass or stainless steel or polyacetal having excellent impact resistance.

  Since the rotating member 7 itself is an annular member that rotates with respect to the shaft 6, the structure is simple and is not easily damaged.

  As shown in FIG. 1, a brake portion 13 made of a resin such as ABS or polyester is fixed to the rear end of the insertion member 3. On the other hand, in order to frictionally slide with the brake part 13, the inner side surfaces 2 a and 2 b on both sides on the distal end side of the outer cylinder 2 may be used.

  Further, as shown in FIG. 2, a member that functions as a braking means 20 that frictionally slides with the insertion member 3 is raised on the bottom 2c of the outer cylinder 2 by pressing, or a synthetic resin material or a metal material is welded. It may be provided by fixing means such as a rivet. Moreover, you may provide the braking means 20 in the side part 2d (refer FIG. 2) of the outer cylinder 2. FIG.

  In this way, when the door D is fully opened, the brake portion 13 of the insertion member 3 frictionally slides with the outer cylinder 2 and the braking means 20 of the outer cylinder 2 is inserted into the insertion member 3 immediately before the door D is fully opened. Therefore, the moving speed of the insertion member 3 can be reduced. Therefore, the impact of the collision can be further reduced, and the rotating member 7 is not easily damaged.

  1-4, a contact piece 15 is provided at the rear end of the insertion member 3, while a step 16 is provided inside the outer cylinder 2. The contact piece 15 prevents the insertion member 3 from coming out of the outer cylinder 2 by contacting the step portion 16 when fully open. At the same time, the rotating member 7 can be prevented from being damaged by intensively receiving the impact when fully opened.

  The material of the stopper 9 is not particularly limited in the present invention. However, if the stopper 9 is made of a synthetic resin material having elasticity and impact resistance, such as ABS resin or polyester, the impact absorbing effect is high. There is an advantage that damage to the rotating member 7 can be further prevented.

  As shown in FIGS. 6 to 7, in the holding mechanism in the present embodiment, when the door D is fully opened, almost the entire insertion member 3 is pulled out from the outer cylinder 2, and FIGS. 1 (a) and 1 (b). As shown, the rotating member 7 collides with the teeth 8 while rolling on the surface of the inner side surface 2a of the outer cylinder 2, then gets over the teeth 8, and then collides with the stopper 9 and stops. When the door D is fully opened, the rotating member 7 is locked to the valley portion 11 between the teeth 8 and the stopper 9 as shown in FIG. Thereby, the insertion member 2 and the door D are hold | maintained in a fully open position.

  When the door D is released from the fully open state, if the door D is closed a little harder, the rotating member 7 in the trough 11 collides with the teeth 8 and then climbs over the teeth 8 and again passes through FIG. 1 (a). The fully open state is released.

  In the present embodiment, the door has been described as an example of the object to which the door opening degree adjuster of the present invention is attached. However, the present invention is not limited to this, and the door, window, or other fully opened state is described. It can be applied to joinery or furniture that needs to be held in a state.
