Further, even when the initially appropriate engaged portion 2a of the catcher body 2 and the engaged portion 1a of the striker body 1 are displaced from each other in the height direction y due to aging or the like, the engaging portion 1a In the moving range of, the engaged portion 1a can be appropriately engaged with the engaged portion 2a, and it is not necessary to take special measures in such a case.

(First example)
In the first example shown in FIGS. 1 to 10, the assist unit 3 has a configuration in which the catcher body 2 is movably housed in the casing 4 long in the left-right direction x in the length direction of the casing 4. There is.

The casing 4 has a form in which the front and rear side plate portions 4a along the length direction thereof are connected by end plate portions 4b at both ends of the front and rear side plate portions 4a.

The casing 4 has a first space 4c (upper space in FIG. 9) and a second space 4d (FIG. 9) located on one side of a virtual straight line z (see FIG. 9) that divides the casing 4 into upper and lower parts. In the space below).

One of the end plate portions 4b of the casing 4 is formed only on the second space 4d side, and the portion where the end plate portion 4b of the other end plate portion 4b is not formed is the introduction portion 4e of the striker body 1. When the movable body M is moved to the first moving position, the striker body 1 enters the casing 4 from the introduction portion 4e and comes into contact with the catcher body 2 temporarily held at the position before the start of assist.

Guide grooves 5a configured as openwork grooves constituting the temporary holding means 5 are formed in the front and rear side plate portions 4a of the casing 4, respectively. The guide groove 5a has a bent portion formed between a lateral groove portion 5b formed along the virtual straight line z (see FIG. 9) and a front end portion on the introduction portion 4e side of the lateral groove portion 5b. It is provided with a vertical groove portion 5c that continues to the two spaces 4d side.

The catcher body 2 rotatably supports the first part 2c provided with the engaged portion 2a, the second part 2h abutting on the striker body 1, and the first part 2c, and also supports the second part 2h. It is equipped with a third part 2n that is supported so that it can be slidably moved in the left-right direction x.

The first part 2c is a mountain-shaped engaged portion formed between a front end 2d located on the introduction portion 4e side, a rear end 2e opposite to the front end 2d, and the front end 2d and the rear end 2e. It has 2a. The engaged portion 2a is adapted so that its top portion 2b is located on the first space 4c side. At the front end 2d of the first part 2c, a first protrusion 2f that fits in the guide groove 5a is formed before and after the front end 2d, respectively. The first part 2c is provided with a second protrusion 2g that fits in the guide groove 5a at a position located on the virtual straight line z between the engaged portion 2a and the rear end 2e, and is not shown. In the example of, it is rotatably supported by the third part 2n at the position of the second protrusion 2g.

The second part 2h is supported by the third part 2n in the first space 4c. In the second part 2h, the front end 2i located on the introduction portion 4e side is positioned behind the engaging portion 1a of the first part 2c, and is positioned in front of the rear end 2e of the first part 2c. At the same time, the front end 2i is provided with a contact portion 2k protruding toward the introduction portion 4e.

In the illustrated example, a tension coil spring 6 serving as a urging means for the catcher body 2 is housed between the catcher body 2 in the second space 4d of the casing 4 and the other end plate portion 4b of the casing 4. One end of the spring 6 is always fastened to a position between the front end 2d and the rear end 2e of the first part 2c and is always located in the second space 4d, and the other end of the spring 6 is the other end of the casing 4. It is fastened to the end plate portion 4b side.

As a result, in this embodiment, at the position before the start of assist, the catcher body 2 causes the first protrusion 2f of the first part 2c to become the vertical groove portion 5c of the guide groove 5a by the urging of the spring 6. The first part 2c is held in a non-engaged posture in which the top portion 2b of the engaged portion 2a is positioned on the virtual straight line z (FIG. 9).

When the movable body M is moved to the first moving position and the striker body 1 is brought into contact with the contact portion 2k of the second part 2h, the second part 2h retracts and one of the front ends 2i of the second part 2h. The portion 2j hits the rear end 2e side of the first part 2c from the front, and the first part 2c rotates around the position of the second protrusion 2g in a direction in which the engaged portion 2a enters the first space 4c. As a result, the first part 2c of the catcher body 2 is in an engaging posture that enables the engaged portion 2a to be engaged with the engaging portion 1a of the striker body 1. When the first protrusion 2f reaches the bent portion of the guide groove 5a, the first protrusion 2f enters the lateral groove 5b due to the urging of the spring 6, and the catcher body 2 automatically moves to the assist end position (FIG. 10). Will be done.

When the movable body M moved to the second moving position by the assist of the assist device made in this way is relocated from the second moving position to the first moving position, the spring 6 is attached. The first protrusion 2f that has reached the bent portion due to the force enters the vertical groove portion 5c, the first part 2c rotates and is held again in a non-engaged posture, and the engaged portion 2a is engaged with the striker body 1. The portion 1a is released.

Reference numeral 7 in FIG. 6 indicates that the spring 6 of the catcher body 2 is located between the third part 2n of the catcher body 2 in the first space 4c of the casing 4 and the other end plate portion 4b of the casing 4. It is a cylinder constituting a piston damper as a braking means for applying a predetermined braking force to the retreat caused by the casing.

On the other hand, the striker body 1 includes a base 1b as a fixed portion and an arm 1f provided with the engaging portion 1a rotatably combined with the base 1b.

The base 1b has a plate portion 1c that is long in the left-right direction x, and one surface of the plate portion 1c is a mounting surface 1d to the fixed body S or the movable body M. A support portion 1e of the arm 1f is formed on the other surface of the plate portion 1c.

The arm 1f is long in the left-right direction x. The arm 1f includes an engaging portion 1a between the front end 1g on the approach side of the assist unit 3 to the casing 4 and the opposite rear end 1h. At the same time, the arm 1f is rotatably combined with the support portion 1e on the rear end 1h side (the rotation center axis is indicated by reference numeral 1i in FIG. 5). As a result, the arm 1f has a height extending between a position at which a predetermined distance is provided between the front end 1g of the arm 1f and the base 1b (position in FIG. 5) and a position where the front end 1g is in contact with the base 1b. It is movable in the vertical direction y, and the engaging portion 1a formed on the arm 1f is freely movable in the height direction y within a certain range.

In the illustrated example, the engaging portion 1a is a notch portion that is opened on the side of the arm 1f opposite to the side facing the base 1b and is recessed toward the base 1b side.

Further, the assist device includes a deterrent means 8 for suppressing the movement of the striker body 1 in the height direction y in the engaging portion 1a within a certain range. As described above, the catcher body 2 moves in the height direction y when the movable body M reaches the first moving position, and engages the engaged portion 2a with the engaging portion 1a of the striker body 1. However, since the movement of the engaging portion 1a in the height direction y with respect to this is suppressed within a certain range, the engaging portion of the striker body 1 is suppressed by the movement on the catcher body 2 side at this time. 1a is prevented from being pushed up or down to a position where both are not engaged. Further, when the movable body M is relocated from the second moving position to the first moving position, it is pushed up or down by the engaged portion 2a of the catcher body 2 in the same manner as described above, and both are engaged. The case is not unexpectedly solved.

In this example, the deterrent means 8 is a receiving portion 8d formed on the striker body 1 side that enters the receiving portion 8a formed on the catcher body 2 side at the first moving position.

In the illustrated example, the receiving portion 8a is formed on the side of the contact portion 2k of the second part 2h of the catcher body 2. In the illustrated example, the front end 2i of the second part 2h is formed with a contact portion 2k made of an elastic member indicated by reference numeral 2m in the figure, and is located on the imaginary straight line z side of the contact portion 2k. , A receiving portion 8a opened forward is formed.

On the other hand, the receiving portion 8d is formed so as to protrude forward from the front end 1g of the arm 1f of the striker body 1.

The receiving portion 8a includes an upper edge portion 8b located on the contact portion 2k side and front and rear side edge portions 8c, and the second space 4d side is opened (FIG. 7).

As a result, when the movable body M is moved to the first moving position, the front end 1g of the arm 1f of the striker body 1 is brought into contact with the contact portion 2k of the second part 2h of the catcher body 2 and is received. The receiving portion 8d enters the portion 8a, and the movement of the arm 1f in the height direction y, the fitting, and the movement of the engaging portion 1a in the height direction y are suppressed within a certain range.

Further, in this embodiment, an urging member for urging the fixed portion and the engaging portion 1a of the striker body 1 in a direction to separate them from each other is interposed between the fixed portion and the engaging portion 1a. In the illustrated example, an urging member made of a compression coil spring 9 is interposed between the base 1b and the arm 1f, which are fixed portions, and the arm 1f has a predetermined distance between the front end 1g of the arm 1f and the base 1b. It is designed to be positioned by urging at the open position (position in FIG. 5). As a result, when the engagement portion 1a of the striker body 1 is disengaged from the engaged portion 2a of the catcher body 2, the engagement portion 1a is automatically returned to the position before the engagement. ..

Further, in this example, in the introduction portion 4e of the casing 4 constituting the assist unit 3, a guide surface 10 that increases toward the inner side of the casing 4 is provided at a position located on the virtual straight line z. It is formed. As a result, as long as the front end 1g of the arm 1f of the striker body 1 is at the same level as the guide surface 10, the striker body 1 is guided to the guide surface 10 when the striker body 1 enters the casing 4, and the engaging portion 1a Is moved to a predetermined height position in the casing 4, abuts on the contact portion 2k, enters the receiving portion 8d of the receiving portion 8d, and subsequently engages with the engaging portion 1a and the engaged portion 2a. Engagement is ensured.

(Second example)
In the second example shown in FIGS. 11 to 16, the deterrent means 8 is attached to the groove mouth portion of the introduction groove 8e of the engaging portion 1a of the striker body 1 in the assist unit 3 on the inner side of the assist unit 3. It is different from the first example in that it becomes a protrusion 8f provided for the striker body 1 that is caught from the above. Since the other configurations of the second example are the same as or substantially the same as those of the first example, FIGS. 11 to 16 showing the second example show the same or substantially the same components. The same reference numerals as those given in the respective figures showing an example will be added and the description thereof will be omitted.

In this second example, on the first space 4c side of the casing 4, the open portion between the front and rear side plate portions 4a constituting the casing 4 is narrowed by the eaves-shaped portion 11 protruding inward in the direction orthogonal to the side plate portion 4a. The introduction groove 8e is formed between the eaves-shaped portion 11 located on the front side and the eaves-shaped portion 11 located on the rear side. In the illustrated example, the eaves-shaped portion 11 is provided on the casing 4 by a cover 12 attached to the casing 4. The introduction groove 8e starts from a position directly above the engaged portion 2a of the catcher body 2 at the position before the start of assist, with a slight gap between the introduction groove 8e and the introduction portion 4e of the casing 4, and is opposite to the introduction portion 4e side of the casing 4. It continues to the rear end side.

On the other hand, in this second example, the protrusion 8f protruding toward the front (the side plate portion 4a on the front side of the casing 4) and the rear side (side plate portion on the rear side of the casing 4) are located at the front end 1g of the arm 1f of the striker body 1. A protrusion 8f that protrudes toward the 4a side) is provided so that a portion of the arm 1f other than the protrusion 8f can pass through the introduction groove 8e in the height direction y in a state of being inserted into the casing 4 from the introduction portion 4e. However, each of the protrusions 8f is set to be caught from the inside on the groove mouth portion of the introduction groove 8e, that is, the eaves-shaped portion 11.

As a result, even in this example, when the movable body M is moved to the first moving position, the front end 1g of the arm 1f of the striker body 1 becomes the contact portion 2k of the second part 2h of the catcher body 2. Since the protrusion 8f is positioned inside the groove opening of the introduction groove 8e while being abutted, the arm 1f moves in the height direction y, and the engaging portion 1a moves in the height direction y. It is designed to be suppressed to a certain extent.

As a matter of course, the present invention is not limited to the embodiments described above, but includes all embodiments that can achieve the object of the present invention.
