On the other hand, the bracket plate 11 is formed of a rectangular plate having substantially the same width as the case 10, and engaging tabs 16 are provided at the four corners of the side in the longitudinal direction of the rectangular plate. ing. As shown by the arrow in FIG. 1, the claw is formed by bending the engaging piece outward to form the locking portion 17, and bending the end of the bent locking portion 17 inward to form the stopper 18. The size of the claw 16 is formed to be slightly smaller than the opening of the fitting groove 13 formed in the front unit case 1.
[0020]
Further, the gap between the claws 16 provided on one side in the length direction of the bracket plate 11 is the same as the gap between the fitting grooves 13 and the grooves 13 provided in the front unit case 1. Is formed.
[0021]
Therefore, as shown in FIG. 2, the tab 16 of the bracket plate 11 is fitted into the fitting portion 13 ″ of the fitting groove 13 of the front unit case 1 (at this time, the stopper 18 of the claw 16 is inserted into the fitting portion of the groove 13). 13 ”side, when sliding in the holding portion 13 ′ direction, the projection 15 end of the holding portion 13 ′ of the groove 13 and the stopper 18 of the claw 16 come into contact with each other, and the projection 15 of the groove 13 and the claw The 16 locking portions 17 engage with each other as shown in FIG. 3, and the bracket plate 11 locks the front unit case 1.
[0022]
Further, the bracket plate 11 is provided with a plate spring 19 in the middle of the plate body substantially in the width direction, and the plate spring 19 provided in the central portion thereof has one end of the bracket plate 11 as shown in FIG. It is attached to the plate surface, and the other end is raised obliquely from the plate surface. The rising direction of the other end of the raised plate spring 19 is attached so as to be parallel to the fitting direction of the bracket plate 11 described above. Therefore, when the claw 16 of the bracket plate 11 is fitted and attached to the fitting groove 13 of the front unit case 1, the other end of the leaf spring 19 is engaged with the fitting recess 14 on the back surface of the front unit case 1. It is supposed to be arranged in.
[0023]
Further, the tip of the other end of the plate spring 19 raised in this way is curved to form a joint surface 20 by the curvature, and the joint surface 20 engages with the recess 14 on the back surface of the front unit case 1. The engagement from the recess 14 can be smoothly released.
[0024]
In the figure, reference numeral 21 denotes an attachment hole in which a thread groove is cut, and reference numeral 22 denotes an attachment hole for a wood screw. Further, by providing these mounting holes 21 and 22, the bracket plate has an embossed structure in which the central portion is recessed, and the screw that is inserted into the mounting holes 21 and 22 by the embossing for screwing. The head of the end or the inserted wood screw is made not to protrude.
[0025]
This embodiment is configured as described above. Next, a mobile bracket locking mechanism will be described by describing how to attach the front unit case 1 to the bracket plate 11.
[0026]
In this attachment, in order to attach the front unit case 1, first, the bracket plate 11 is attached in the vehicle. For this attachment, the bracket plate 11 may be directly attached to a door, a dashboard or the like with a wood screw or the like, but in this embodiment, for example, a case where the bracket plate 11 is attached to a console in a vehicle by a television stand S shown in FIG. . That is, the television stand S is attached to a console or the like in the vehicle, and the fixing screw of the attached stand S is screwed into the attachment hole 21 provided with the screw groove of the bracket plate 11 and attached.
[0027]
At this time, the mounting direction of the bracket plate 11 is such that the stopper 18 of the tab 16 of the bracket plate 11 is inserted into the insertion portion 13 ″ side of the insertion groove 13 so that the front unit case 1 is not inverted as shown in FIG. Attach so that it is located at.
[0028]
In this manner, the back surface of the front unit case 1 is pressed against the bracket plate 11 attached to the stand S, and the fitting portion 13 of the groove 13 of the front unit case 1 is opposed to the plate spring 19 of the bracket plate 11. In this case, the tab 16 of the bracket plate 11 is fitted. At this time, the joint surface 20 at the tip of the leaf spring 19 is fitted into the recess 14 on the back surface of the front unit case 1 as shown in FIG. As shown in FIG. 2, when the slide 18 is slid in the direction of the arrow until the stopper 18 of the claw 16 fitted in the fitting portion 13 ″ of the groove 13 comes into contact with the protrusion 15 of the groove 13, the claw 16 The engaging portion 17 engages with the holding portion 13 ′ of the groove 16. At this time, the joint surface 20 at the tip of the leaf spring 19 advances into the step of the concave portion 14 on the back surface by the slide, and sliding in the reverse direction is restricted by the step of the concave portion 14.
[0029]
At the same time, the leaf spring 19 presses the claw 16 of the bracket plate 11 against the protrusion 15 of the groove 13 by spring pressure, so that the backlash between the front unit case 1 and the bracket plate 11 is suppressed, as shown in FIG. The front unit case 1 can be attached to the stand S.
[0030]
Thus, in this lock mechanism, the slide of the front unit case 1 in the reverse direction (disengagement direction) is restricted by the step of the recess 14 provided in the front unit case 1 and the plate spring 19, and at the same time, the plate spring 19 Backlash can be prevented by the spring pressure. For this reason, for example, even if vibration due to traveling of the vehicle is applied, the vibration can be absorbed and the front unit case 1 can be supported stably.
[0031]
On the other hand, when removing the front unit case 1 from the bracket plate 11, the front unit case 1 is slid in the direction opposite to the direction in which the front unit case 1 is attached, and the tab 16 of the bracket plate 11 is positioned at the fitting portion 13 ″ of the groove 13. When it is pulled back, the front unit case 1 is lifted by the spring pressure of the leaf spring 19, and the engagement between the claw 16 and the groove 13 is released.Therefore, the front unit case 1 is removed when the front unit case 1 is lifted. The plate spring 19 can be easily removed with one hand by bending the joint surface 20 at the tip of the plate spring 19. Can be easily exceeded.
[0032]
Thus, since this locking mechanism employs a mechanism that locks with the spring pressure of the plate spring 19, the front unit case 1 can be attached to and detached from the bracket plate 11 with a single touch of sliding the front unit case 1. . Further, since no accessory is required and the number of parts is small, the cost can be reduced. Further, since the number of parts is small and there are almost no movable parts, the occurrence of failure is also small.
[0033]
In the embodiment, the front unit separated type in-vehicle transceiver has been described. However, the present invention is not limited to this, and other than this, the locking mechanism includes a main body case such as a car audio and a front unit case. It can be applied to all separable devices.
[0034]
【The invention's effect】
The present invention is configured as described above, and is provided with a recess for engagement on the back surface of the front unit case and a groove for fitting on both sides of the back surface, and a leaf spring and a groove for engagement that engage with the recess for engagement. Since the front case unit can be locked by the elastic force of the leaf spring provided on the bracket, the front unit can be supported strongly and stably against vibration. At that time, the front case unit is locked by the elastic force of the leaf spring, so it is easy to attach and detach, has good operability, and the number of parts can be reduced, so the mobile bracket can be manufactured at low cost.
