Description

[Detailed Description of the Invention] The present invention relates to an attachment/detachment device for an automobile watch or the like that is attached to a dash board of an automobile.

2. Description of the Related Art General-purpose automobile clocks that are installed in various automobiles and automobile clocks that are also used as general desk clocks are often detachably attached to dash boards.

Various attachment/detachment devices have been proposed in the past, but if they are designed to be easy to attach/detach, there is a risk that vibrations from the car, especially instantaneous impacts, may cause the watch to detach from the dash board and fly off, causing an accident. There is a
No device suitable for attaching and detaching an automobile watch was found.

The present invention was devised in view of this point, and its purpose is to provide an attachment/detachment device that strengthens the mounting strength of a car watch in normal times and allows for easy attachment/detachment. With the goal.

The content of the present invention will be explained below based on the embodiments shown in the drawings.

Reference numeral 1 denotes a watch case main body that houses a watch mechanism (not shown), 2 is a mounting plate integrally molded with resin and the watch rear case 3, and the bottom surface 4 of the mounting plate 2 is attached to a dash board (not shown) using screws or the like. is fixed. Guide surfaces 5 and 5' formed on both ends of the flat part of the mounting plate 2 and a pair of L-shaped guide retainers 6 and 6' arranged oppositely on the bottom surface of the watch case body 1 fit into each other. The watch case main body 1 is press-fitted in the vertical direction. Further, a pair of parallel elastic locking pieces 7 and 7' extend from the watch rear case 3, which constitutes a part of the mounting plate 2.
The locking claws 8 and 8' formed at the tips of the locking pieces 7 and 7' slide inside the watch case body 1 and fit into the notch holes 9 and 9' on the bottom of the watch case body 1, and at the same time, the locking claws 8 and 8' are inserted into the notch holes 9 and 9' on the bottom of the watch case body 1. It is configured to lock with the side walls 10 and 10' to fix the watch case body 1 in the front-back sliding direction.

The locking claws 8 and 8' are formed into a substantially trapezoidal shape,
It has gentle slopes 8a and 8a' on the distal end side (i.e., the attachment side) and relatively steep slopes 8b and 8b' on the opposite side (i.e., the removal side),
The outer ends of the ridge lines of the detachment side inclined surfaces 8b and 8b' are cut off obliquely to form inclined surfaces 8c and 8c' in the torsional direction.

When using the present device to mount an automobile watch, first the mounting plate 2 is fixed to the dash board with screws or the like. Next, if the guide retainers 6 and 6' of the watch case body 1 and the guide surfaces 5 and 5' of the mounting plate 2 are fitted and slid backward, the mounting plate 2
The locking claws 8 and 8' slide along the inner plane of the watch case body 1 while being bent by the mounting side inclined surfaces 8a and 8a', and fit into the notch holes 9 and 9' of the watch case body 1, It is locked by its side walls 10 and 10'. At this time, since the mounting side inclined surfaces 8a and 8a' of the locking claws 8 and 8' are formed relatively gently, the mounting can be easily performed. On the other hand, since the detachment side inclined surfaces 8b and 8b' are relatively steep, they firmly engage with the side walls 10 and 10' of the cutout holes 9 and 9', and are not easily detached.

When removing the watch case body 1 from the mounting plate 2, the watch case body 1 may be pulled forward (in the C direction) while being twisted in the directions A and B in FIG. That is, when twisted in the direction A, one of the locking claws 8 is released from the side wall 10 of the notch hole 9 along the slope 8c in the twisting direction, and when the locking claw 8 is then twisted in the direction B, the other locking claw 8 is released. ' is released from the side wall 10' of the cutout hole 9' along the slope 8c' in the torsional direction, so even if the separation side slopes 8b and 8b' are formed relatively steeply, it can be easily removed. Both 8 and 10, 8' and 1
0' is disengaged. Therefore, if the watch case body 1 is pulled forward (direction C), the fitting between the guide retainers 6 and 6' of the watch case body 1 and the guide surfaces 5 and 5' of the mounting plate 2 will be released, so that the watch case can be easily removed. It can be removed from the mounting plate 2 of the main body 1.

In the above embodiment, the locking claws 8 and 8' were provided on the mounting plate 2, and the cutout holes 9 and 9' were provided on the watch case body 1, but it is of course possible to do the opposite. . Further, the members to be engaged by the locking claws 8 and 8' are not limited to the side walls 10 and 10' of the notch holes 9 and 9', but may be any engagement member such as an engagement protrusion. good.
Furthermore, the shapes of the locking claws 8 and 8', which constitute the main part of the present invention, are not limited to the above embodiments.
For example, it may be formed into a mountain shape or a dome shape.
In short, it has a gentle slope on the tip side, and the slope on the disengagement side is at a relatively steep angle so that it does not easily separate from the other engagement member, and also forms a slope in the torsional direction. It is fine as long as it is something.

As described above, the present invention provides a pair of engaging members on either the mounting plate fixed to the dash board of an automobile or the watch case body,
A pair of locking pawls are provided on the other side of the engagement member to fit together after sliding while being in pressure contact with the engagement member, and the locking pawls have a gently sloped surface on the tip side, and the slope on the disengagement side is compared to Since the angle is steep and the outer end of the ridge line of the detachment-side inclined surface is cut obliquely to provide an inclined surface in the torsional direction, when the watch case body is removed from the mounting plate, the inclined surface in the torsional direction can be removed. The watch can be easily removed from the dash board, and the inclined surface on the removal side is at a relatively steep angle, which prevents accidents such as the car watch becoming detached from the dash board and being scattered due to car vibrations or shocks. Its practical effects are extremely large.
