Description

  The present invention relates to a retractor position adjusting jig and a retractor unit for adjusting the position of a receiving portion of the retractor.

  2. Description of the Related Art A retracting device that generates a retracting force for retracting a hinged door of a building or furniture is known (see Patent Document 1). The retracting device includes a receiving part attached to one of the frame and the hinged door, and a retractor main body attached to the other of the frame and the hinged door. The retracting device main body is provided with an arm that rotates from the pulled-out state to the retracted state and retracts the receiving portion. When the arm in the pulled-out state engages with the receiving portion (for example, when the shaft of the receiving portion fits into the groove of the arm or the groove of the receiving portion fits into the arm shaft), the arm rotates in the retracting direction. Pull the receiving part. A coil spring for generating a pulling force is provided inside the pulling device main body.

  By the way, when attaching a receiving part to any one of a frame and a hinged door, it is necessary to adjust the position of a receiving part to the position engaged with the arm of the state where the receiving part was pulled out. This is because the retracting device cannot operate normally unless the receiving portion engages with the arm that has been pulled out. The conventional method for adjusting the position of the receiving part is to rotate the hinged door in the closing direction little by little to bring the arm pulled out closer to the receiving part, compare the position of the tip of the arm with the position of the receiving part, and receive it at the tip of the arm. This is done by adjusting the position of the receiving part so that the parts engage.

International Publication No. 2011-021630

  However, in the conventional method for adjusting the position of the receiving portion, the arm in the pulled-out state may hit the receiving portion, and the arm may rotate to the retracted state. If the arm is rotated to the retracted state, it is not possible to know where the receiving portion should be positioned. For this reason, it is necessary to pull out the retracted arm again, but the elastic force of the coil spring inside the retracting device main body is strong, and a large force is required to pull out the retracted arm again. As described above, the conventional method for adjusting the position of the receiving portion has a problem that workability is poor.

  Then, an object of this invention is to provide the position adjustment jig for retractors which can adjust the position of the receiving part of a retractor easily.

  In order to solve the above-described problems, an embodiment of the present invention includes a receiving portion attached to one of a frame and a hinged door, and the other attached to the other of the frame and the hinged door, and is rotated and received from a drawn state to a retracted state. A retractor main body having an arm for retracting the part, and a retractor position adjusting jig used in the retractor, wherein the main body part is positioned on the retractor main body, and projects from the main body part in the arm pull-out direction. And a protrusion having a positioning portion for positioning the receiving portion so that the arm can retract the receiving portion.

  According to the present invention, if the position adjustment jig for the retracting device is positioned on the retracting device main body and the receiving portion is positioned by the positioning portion, the receiving portion can be positioned at a position where the arm can be retracted. When positioning the receiving portion, the pulled-out arm is not pulled into the receiving portion, so that workability is improved.

  A retractor position adjustment jig (hereinafter simply referred to as a position adjustment jig) according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, a retracting device in which the position adjusting jig of this embodiment is used will be described.

  FIG. 1 shows a hinged door 2 attached to the frame 1 so as to be opened and closed. The retracting device includes a receiving shaft 4 as a receiving portion attached to the frame 1, and a retracting device main body 3 (see FIG. 2) attached to the hinged door 2. The retracting device main body 3 includes an arm 5 that rotates from the pulled-out state to the retracted state and retracts the receiving shaft 4. The retracting device has a retracting function and a damper function, and softens the impact when closing the hinged door 2 so that the hinged door 2 closes slowly and surely.

  As shown in FIG. 2, the retracting device main body 3 is embedded in the upper part of the hinged door 2, and is formed in a rectangular parallelepiped shape that is elongated in the opening direction of the hinged door 2. In the upper part of the hinged door 2, a square digging 2 a that matches the shape of the retractor main body 3 is processed. The retracting device main body 3 is inserted into the digging 2 a, and the retracting device main body 3 is fixed to the hinged door 2 with a screw 6. The retractor main body 3 is provided with an arm 5 so as to be rotatable around a horizontal axis. The arm 5 is formed with a groove 5 a for receiving the seat shaft 4. When the arm 5 retracts the seat shaft 4, the seat shaft 4 slides along the groove 5a while being fitted in the groove 5a.

  As shown in FIG. 3, the receiving shaft 4 is attached to the lower surface of the upper frame 1 a of the frame 1. The seat shaft 4 is supported by the seat body 7. The receiving shaft 4 and the receiving body 7 constitute a receiving seat 8. The upper frame 1a is machined with a dug 9 having a quadrangular cross section having a two-stage depth according to the shape of the receiving body 7. The receiving seat 8 is fixed to the center of the digging 9 with a screw 10. The receiving shaft 4 can be adjusted in its three-dimensional position (frontage direction (left-right direction) position, vertical direction position, depth direction (front-rear direction) position).

  The structure of the retractor main body 3 is as follows. FIG. 4 shows a horizontal sectional view of the retractor main body 3. The retracting device main body 3 includes a case 11, an arm base 12 incorporated in the case 11, an arm 5 rotatably supported by the arm base 12, a slider crank mechanism 21 that applies torque in a direction pulled out or pulled in the arm 5, A damper mechanism 22 is provided for alleviating an impact when the arm 5 is retracted.

  The slider crank mechanism 21 includes a first link 13, a slider 14, a coil spring 15, and a spring base 16. One end of the first link 13 is connected to the arm 5 at a position eccentric from the rotation axis of the arm 5, and the other end of the first link 13 is connected to the slider 14. The slider 14 is supported by the case 11 so as to be slidable in one direction. The coil spring 15 is interposed between the slider 14 and the spring base 16 and applies a biasing force to the slider 14.

  The damper mechanism 22 includes a slide block 31, a damper 32, a damper base 34, and a damper adjustment shaft 33. The slide block 31 is formed with a long hole 31a through which the damper shaft 5c of the arm 5 passes. The slide block 31 is supported by the case 11 so as to be slidable in one direction. When the arm 5 rotates, the slide block 31 slides in one direction. The damper 32 is interposed between the slide block 31 and the damper base 34. As the damper 32, a telescopic damper in which a rod 32b strokes with respect to the main body portion 32a is used. When the arm 5 rotates in the retracted direction, the damper 32 contracts and a damper force is generated. For this reason, even if it tries to rotate quickly in the direction in which the arm 5 is pulled, the damper 32 rotates the arm 5 slowly. A damper base 34 is coupled to the case 11. A damper adjusting shaft 33 for adjusting the strength of the damper 32 is incorporated in the damper base 34. By rotating the damper adjusting shaft 33, the position of the main body portion 32a of the damper 32 is adjusted.

  The movement of the retractor main body 3 is as follows. The arm 5 rotates from the pulled-out state shown in FIG. 5C to the retracted state shown in FIG. In the pulled-out state shown in FIG. 5C, the slider crank mechanism 21 applies torque in the direction of further pulling out to the arm 5. For this reason, the pulled-out state of the arm 5 is maintained. When the seat shaft 4 hits the arm 5 in the pulled-out state, the arm 5 rotates in the retracting direction as shown in FIG. When the arm 5 further rotates in the retracting direction and exceeds the thought point of the slider crank mechanism 21, the slider crank mechanism 21 applies a torque in the retracting direction to the arm 5. As a result, the arm 5 automatically rotates to the retracted state shown in FIG. In the retracted state, the slider crank mechanism 21 further applies a torque in the retracting direction to the arm 5. For this reason, the retracted state of the arm 5 is maintained.

  Further, as shown in FIG. 5 (c) → FIG. 5 (b) → FIG. 5 (a), when the arm 5 rotates from the pulled-out state to the retracted state, the slide block 31 contracts the damper 32. Force is generated. For this reason, the arm 5 rotates slowly in the retracting direction.

  The structure of the seat 8 is as follows. FIG. 6 shows a detailed view of the seat 8. 6 (a) shows a side view of the seat 8, FIG. 6 (b) shows a vertical sectional view, FIG. 6 (c) shows a bottom view, and FIG. 6 (d) shows a receiver with a decorative cover attached. A bottom view of the seat 8 is shown. As shown in FIG. 6A, the seat 8 includes a seat shaft 4 and a seat body 7 that supports the seat shaft 4. As shown in FIGS. 6A and 6C, the seat shaft 4 can be adjusted in the front-end direction (left-right direction), vertical position, and depth direction (front-rear direction). ing.

  As shown in FIG. 6C, the receiving body 7 is inserted into the digging 9 of the frame 1. The length in the frontage direction of the digging 9 is longer than the length in the frontage direction of the receiving body 7. The seat body 7 is formed with a long hole 7a through which the screw 10 (see FIG. 3) passes. The position of the seat shaft 4 can be adjusted in the frontage direction by loosening the screw 10 and sliding the receiving body 7 in the frontage direction. After the adjustment, if the screw 10 is tightened, the seat shaft 4 is fixed in the frontage direction.

  As shown in FIG. 6 (b), the receiving shaft 4 is telescopically fitted to the shaft support 42 in a state of protruding by the coil spring 41. A screw 42 a is formed on the outer peripheral surface of the shaft support 42, and the shaft support 42 is coupled to the seat body 7 with a screw. The vertical position of the receiving shaft 4 can be adjusted by rotating the shaft support 42. When the fixing nut 44 (see also FIG. 6C) is loosened and the shaft support 42 is rotated rightward, the seat shaft 4 is retracted into the seat body 7. When the shaft support 42 is rotated leftward, the receiving shaft 4 pops out from the receiving body 7. After the adjustment, a flathead screwdriver or the like is inserted into the groove 42a of the shaft support 42, the shaft support 42 is prevented from rotating, and the fixing nut 44 is tightened with a spanner or the like. Fixed to.

  The reason why the coil spring 41 is interposed between the receiving shaft 4 and the shaft support 42 is that the receiving shaft 4 fits into the groove 5a of the arm 5 even when the arm 5 is retracted. is there. When the hinged door 2 in which the arm 5 is retracted is closed, the receiving shaft 4 gets over the inclined portion 5b (see FIG. 2) on the side of the groove 5a of the arm 5 and fits into the groove 5a of the arm 5. When the receiving shaft 4 gets over the inclined portion 5b, the receiving shaft 4 compresses and retracts the coil spring 41. Thereafter, the receiving shaft 4 protrudes by the spring force of the coil spring 41 and fits into the groove 5 a of the arm 5.

  As shown in FIG. 6B, the seat body 7 includes an adjustment body 45 to which the shaft support 42 is coupled with a screw, a base plate 46 coupled to the adjustment body 45 via a depth direction fixing screw 47, Is provided. The base plate 46 is formed with a long hole (not shown) long in the depth direction through which the depth direction fixing screw 47 is passed. On the contact surface 49 between the adjusting body 45 and the base plate 46, jaggedness (continuous irregularities) is formed. If the depth direction fixing screw 47 is loosened, the position of the seat shaft 4 in the depth direction can be adjusted. After the adjustment, if the depth direction fixing screw 47 is tightened, the seat shaft 4 is fixed in the depth direction. As shown in FIG. 6D, after the position of the seat shaft 4 is adjusted, the seat body 7 is covered with a decorative cover 48.

  The structure of the position adjustment jig is as follows. FIG. 7 shows a perspective view of the position adjusting jig 51 of the present embodiment.
