  In the above-described conventional structure, for example, the drawer body is almost entirely automatically slid from the drawing position to the drawing direction. However, a corresponding strong pulling operation force is required from the drawing position to the drawing direction, resulting in poor usability. Further, as a lock mechanism for locking the drawer body against the urging force of the spring 65, the drive pin 55 is pulled out of the slot 61 by the forward inclination of the inclined portion 60 and engaged with the inclined side wall 62. The resultant force is weak, and there is a possibility that the lock is released by vibration or the like. Moreover, in the conventional structure, there is a risk that the relative position between the inclined portion 60 and the drive pin 55 may be shifted due to a change in the loading amount and the storage load of the drawer and may not operate normally.

  The object of the present invention is suitable as a pull-in mechanism for pulling the movable body with an urging force from the middle, in order to prevent rebound when the movable body is pushed in vigorously or to prevent the occurrence of an incomplete pushing state of the movable body. In particular, even if the relative positions of the engagement-related members change, the change is absorbed to maintain a good operation, thereby preventing the occurrence of malfunction and improving the reliability.

In order to achieve the above object, the present invention of claim 1 is directed to a striker provided on one of a fixed body and a movable body movably supported by the fixed body, and on the other of the movable body. A state in which the striker and the catcher are engaged with a catcher that is detachably engaged with the striker at a predetermined movement position; and an urging means capable of accumulating urging force during the movement of the movable body. In the retracting mechanism that pulls in the movable body by the urging force accumulated in the urging means, the case is attached to one of the fixed body and the movable body and the striker is disposed together with the urging means, and the fixed A holding member attached to the other of the body and the movable body and supporting the catcher so as to be movable in the vertical direction, a guide groove provided in the case, and the cap Provided catcher over consists protrusion that slides the guide groove, the change when the relative position is turned into strange to regulate the relative position between the striker and the catcher, relative to said holding member said catcher And a guide means for moving up and down by a predetermined dimension to absorb the protrusion so that the protrusion can be fitted into the guide groove .
In contrast, the invention of claim 2, and also the invention and to "... Oite", the striker mounted movably in the vertical direction to the fixed body and arranged with said biasing means A case, a holding member attached to the movable body and supporting the catcher, a guide groove provided in the case, and a protrusion provided in the catcher and sliding on the guide groove, When the relative position changes by regulating the relative position between the striker and the catcher, the change is absorbed by moving the striker up and down by a predetermined dimension with respect to the fixed body via the case. And a guide means that can be fitted into the guide groove .

  In the present invention described above, the fixed body includes a drawer body main body and a sliding door frame main body. The movable body is a drawer body, a sliding door, or the like, and may be in a relationship of reciprocating with respect to the fixed body. The striker and the catcher are provided corresponding to the fixed body and the movable body, and are engaged at a predetermined movement position of the movable body with respect to the fixed body (for example, when the movable body is a drawer body, the drawer body is being pushed in). In addition, any relationship may be used as long as the movable body can be retracted by the urging force accumulated in the urging means. As a specific example, if it is the structure of patent document 1, a drive pin will correspond to a catcher and an inclined part will correspond to a striker.

Each of the above inventions is more preferably embodied as follows. That is, the guide groove is a configuration that has been formed larger vertical interval than the other groove portions groove doorway portion (claim 3).

  In the first aspect of the invention, for example, if the movable body is a drawer, even if the relative position between the striker and the catcher is displaced or changed due to a change in the load of an article stored in the drawer, etc. The striker and the catcher are corrected to the normal position by the change absorbing action of the guide means and can be engaged. Thereby, as a drawing-in mechanism, the malfunctioning resulting from a relative position shift can be prevented reliably, and thereby quality and reliability can be improved.

At the same time, the striker is arranged in the case together with the biasing means and unitized, and the catcher is supported by the holding member and unitized, so both are easy to handle and attach to a fixed body or movable body. Are better. Further, since the catcher is supported so as to be movable by a predetermined dimension with respect to the holding member, the position can be changed within the allowed movement range and adjusted to the optimum position with respect to the striker. Further, since the catcher is slid in a state in which the protrusion is fitted to the guide groove of the case attached to the fixed body side, stable engagement with the striker can be maintained.

  On the other hand, in the invention of claim 2, instead of the configuration in which the catcher of claim 1 is supported so as to be movable by a predetermined dimension with respect to the holding member, the striker moves by a predetermined dimension with respect to the fixed body via the case. Since it is attached in a possible manner, the position can be changed within the allowable movement range and adjusted to the optimum position with respect to the catcher.

(Operation) The operation of the above retracting mechanism will be described in detail with reference to FIGS. 3 and 4 and FIGS. 7 to 9 show main operations assuming the use example of FIG. 6, and are simplified or modeled in order to clarify the relationship between the members.

(1) First, the operation of the striker assembly A will be clarified. The assembly A is switched between an urging force accumulation state in which the coil spring S accumulates an urging force as shown in FIG. 3 and an urging force release state in which the coil spring S releases an urging force as shown in FIG. In this retracting mechanism, the coil spring S accumulates the urging force to the maximum through the sliding of the arm 3 in the urging force accumulation state. The arm 3 locks the shaft portion 31b in the locking hole 15b. In the damper 34, the piston rod 36 is largely pulled out from the cylinder 35. When the shaft portion 31b is unlocked from the locking hole 15b and released from the horizontal hole 15a from this accumulated biasing force state, the striker 33, the arm 3 and the slider 2 are integrated horizontally by the biasing force of the coil spring S. It is slid along the hole 15a. This unlocking is performed with the engagement of the catcher assembly B (the catcher 5) with the striker 33 as will be described later. When unlocked, the catcher assembly B slides in conjunction with the arm 3 while maintaining the engagement state of the striker 33 and the catcher 5, that is, automatically pulled in while being braked by the dampers 34 and 37. Will be. In this retracting mechanism, the coil spring S releases the urging force or minimizes the urging force through the sliding of the arm 3 in the urging force releasing state. The arm 3 has a shaft portion 31b disposed at an appropriate location in the horizontal hole 15a. The damper 34 has the piston rod 36 most immersed in the cylinder 35.

(2) FIG. 7 shows a change absorption operation in which the guide means 7 corrects the positional relationship between the catcher assembly B and the striker assembly A before the catcher assembly B is engaged. In the usage example of FIG. 6 described above, for example, the relative position between the catcher 5 of the catcher assembly B and the striker 33 of the striker assembly A changes due to a change in the loading amount or the storage load of the drawer body 8. The guide means 7 solves the problem that the catcher 5 and the striker 33 are not normally engaged. That is, when the catcher assembly B is approached to the striker assembly A as shown in FIG. 7B, the guide means 7 (a) the catcher-side protrusion 53 is fitted into the guide groove 16 of the case 1. Since the catcher 5 (the lower engaging portion 52 and the claw member 45) and the striker 33 are accurately positioned because of being slid in the state, (a) the protrusion 53 has a wide groove entrance / exit portion of the guide groove 16 The position of the catcher 5 (the lower engaging portion 52 and the claw member 45) and the striker 33 in the groove width direction (that is, the vertical position) changes because it is received while being centered in the narrow groove portion 16b. Even if it is done, it is corrected efficiently, (c) Whether the catcher 5 (the lower engaging portion 52 and the claw member 45) is supported by the holding member 5 so as to be movable by a predetermined dimension. Be adjusted to the optimum position relative to the striker 33 changes the position within the allowed moving range, and efficiently and reliably absorb a change in the relative position by their malfunction eliminating operation.

(3) FIG. 8 shows a retracting operation of a movable body such as a drawer when the catcher assembly B is engaged with the striker assembly A and is pulled by the biasing force. That is, in this retracting mechanism, when the catcher assembly B is approached to the striker assembly A as shown in FIG. 8A, first, the claw member 45 of the catcher 5 resists the bias of the above-described piece portion 46. The striker 33 moves upward and passes through the striker 33. At the same time, the striker 33 is pushed upward or obliquely upward by the lower engaging portion 52 (tapered shape thereof), thereby being released from the locking hole 15b to the horizontal hole 15b and locked. Canceled. By releasing the lock, the catcher assembly B maintains the engagement between the catcher 5 (the lower engaging portion 52 and the claw member 45) and the striker 33 as shown in FIG. 8B, and the arm 3 and the slider 2 are coiled. It is slid by the urging force of the spring S, and is pulled in conjunction with the sliding. In the use example of FIG. 6 described above, the drawing body 8 is automatically pulled to the final pushing position (while being braked by the braking means 6) by the urging force accumulated in the coil spring S from the middle of being pushed in. Thus, the rebound when the drawer body 8 is pushed in vigorously is prevented, and the occurrence of an incomplete push-in state of the drawer body 8 is prevented.

(4) FIG. 9 shows an operation when the movable body such as the above-described drawer body 8 is moved again from the retracted state in FIG. 8B in the drawing direction to release the engagement. That is, in this retracting mechanism, in the process in which the catcher assembly B is again moved away from the striker assembly A as shown in FIG. 9A, first, the striker 33 is moved to the catcher 5 (the lower engaging portion 52 and the claw member). 45) is engaged with the locking hole 15a, which is one step lower than the horizontal hole 15b, is pushed by the claw member 45 and enters the locking hole 15a, and then catcher assembly B As shown in FIG. 9B, the catcher 5 (the lower engaging portion 52 and the claw member 45) releases the engagement with the striker 33 and is moved alone in the operation direction. Further, in this drawer mechanism, the catcher assembly B is shown in FIG. 8B by the pulling operation of the drawer body 8 and the like while the striker 33 is engaged with the catcher 5 (the lower engaging portion 52 and the claw member 45). When moved to the position 9 (a), the striker 33, that is, the arm 3 and the slider 2 are also moved in the same direction in conjunction with each other, so that an urging force is accumulated in the coil spring S. This urging force accumulation is until the catcher 5 of the catcher assembly B is disengaged from the striker 33.

(Modification) FIG. 10 shows a modification of the retracting mechanism. In this modification, the striker 33 is attached to a fixed body such as the storage body 9 via the case 1 so as to be movable by a predetermined dimension. In this description, the same members as those in the above embodiment and the same functional parts are denoted by the same reference numerals, and redundant descriptions are omitted as much as possible. This drawing mechanism is obtained by changing the attachment portion of the case 1 constituting the striker assembly A with respect to the above-described embodiment. The mounting portion 190 is provided at a plurality of locations of the case 1, and the holes 190 a into which the stoppers M such as screws are inserted are formed as long holes whose vertical dimension is larger than the width. In this drawer mechanism, the striker assembly A is attached by inserting the stopper M into the hole 190 a that is vertically long with respect to the inner surface of the storage body 9, so that the striker 33 has the length of the hole 190 a through the case 1. It is possible to move by a dimension proportional to. As a result, even if the catcher 5 of the catcher assembly B is simplified and formed integrally with the holding member 4 as the guide means 7 described above, the striker 33 is within the allowable movement range via the case 1. The position can be changed by adjusting to the optimum position with respect to the catcher 5.

  Note that the retracting mechanism of the present invention only has to substantially have the configuration specified in claim 1, and the details can be variously changed and expanded as necessary.
