Description

  The present invention relates to an attachment mechanism for attaching a device body such as an electronic device body to a predetermined attachment portion using a bracket.

  As an attachment mechanism for attaching the electronic device to the fixed portion, for example, both side surfaces of the case of the electronic device are sandwiched by brackets attached to the fixed portion, and screws loosely inserted into the bracket are connected to both sides of the case. An attachment mechanism configured to attach the electronic device to the fixed portion by screwing into a screw hole formed on the surface is conceivable.

However, in the case of the mounting mechanism configured as described above, it is surely strong enough to mount a relatively large electronic device, but in order to tighten or loosen the screws during mounting or dismounting, It is necessary to operate the driver from both sides. Therefore, it is not desirable to employ such a driver in a lower space of a dashboard of a passenger car where it is difficult to secure an operation space.
Therefore, instead of operating from both sides of the bracket, an attachment mechanism that can be attached and detached from the front side of the bracket or the electronic device is preferable. In the case of such a mechanism, in order to support the weight of the electronic device, rail-shaped grooves are formed on both side surfaces of the electronic device, and the ridge formed on the inside of the bracket is passed through the groove, An apparatus configured to support the weight of an electronic device is disclosed in Patent Documents 1 and 2, for example.

  The device bracket mounting device described in Patent Document 1 is intended to provide a device bracket mounting device that facilitates mounting work of the bracket to the device body and can reduce the overall width of the device. A protrusion formed on both sides of the device body, a groove formed in the protrusion along the longitudinal direction thereof, and a direction substantially perpendicular to the longitudinal direction of the protrusion on the both sides so as to be continuous with the protrusion. A U-shaped bracket having an engagement piece fitted into the groove at both ends, and a minute protrusion formed on the inner surface of the groove and the outer surface of the bracket facing the inner surface. Is provided.

The set mounting apparatus described in Patent Document 2 is a set mounting apparatus in which a substantially cylindrical bracket is fixed to a vehicle body, and an in-vehicle set is inserted into the bracket for mounting. A lever is provided, and the bracket is provided with a recess or pin that engages with the pin or recess of the lock lever, and the recess engages with the pin by the elasticity of the recess.
In addition, Patent Document 2 relates to a structure for mounting a set such as a vehicle-mounted radio device to a bracket as a conventional technique. By fitting a groove formed on a side portion of the set and a lower end of the bracket, A configuration is described in which the movement in the direction is restricted and the movement of the set in the front-rear direction is restricted by screwing the ear part of the set with the ear part of the bracket.

However, in the thing of patent document 1, since it is not the structure which controls the movement to the front-back direction of a bracket completely, an electronic device cannot be fixed reliably.
Moreover, in the said structure described as patent document 2 as a prior art, although it will surely be able to fix using a screw, there exists a danger of dropping a screw, when attaching and detaching the said screw. In addition, it takes time and effort, and it is necessary to hold the electronic device main body with one hand, which causes a safety problem. Moreover, in the structure of patent document 2, although the rotation type lock lever and the elastic engagement structure are described, it is a very complicated structure.

Below, the bracket attachment apparatus A of Example 1 is demonstrated with reference to FIG.
Reference numeral 1 denotes an electronic device body such as an in-vehicle wireless communication device, which has a substantially rectangular parallelepiped basic shape, and is provided with operation buttons, a display panel, etc. on one side which is the front side in the mounted state. The lateral grooves 2, 2 into which the ridges 6, 6 of the bracket 5 are inserted are formed on the left and right side surfaces of the bracket 5 so as to be substantially horizontal in the attached state along the both side surfaces. These lateral grooves 2 and 2 are formed in a straight line, and the depth thereof is, for example, about 1 mm to 5 mm in depth, and the width is sufficient to allow easy insertion of the ridges. It is considered as a width with a lot of room.

On both side surfaces of the electronic device main body 1, longitudinal grooves 3 and 3 orthogonal to the lateral grooves 2 and 2 are formed on the front side of the lateral grooves 2 and 2. The vertical grooves 3 and 3 are not limited to being orthogonal to the horizontal grooves 2 and 2, and need not be linear, and may have non-parallel portions.
The longitudinal grooves 3 and 3 may have a “Z” shape or an “L” shape as shown in FIGS.
And it is comprised so that an antenna, a power cable, etc. can be connected to one side used as the back side in the attachment state of the said electronic device main body 1. FIG.

The bracket 5 is for fixing the electronic device main body 1 to a predetermined mounting position, and is configured to be fixed to a predetermined mounting position such as a lower portion of a dashboard of a passenger car by a fixing means (not shown). Yes.
The bracket 5 has a “U” -shaped cross-section opened upward, and is configured so that the electronic device main body 1 can be accommodated in the internal space thereof.
Specifically, ridges 6, 6 projecting inward are formed on both side surfaces of the bracket 5. Reinforcing ribs are formed on both side surfaces and the bottom surface of the bracket 5.
Further, tongue portions 7, 7 projecting outward are formed at the front end portion of the bracket 5, and plate-like slide members 8 as longitudinal groove engaging members are formed on the tongue pieces 7, 7. , 8 are arranged to be slidable from the outside to the inside. The shape of the tip of the slide members 8 and 8 is also made to match the shape of the longitudinal grooves 3 and 3. For example, when the shape of the longitudinal grooves 3 and 3 is a “Z” shape as shown in FIGS. 1 and 3, the shape of the tips of the slide members 8 and 8 is also the same Z shape.
The bracket mounting device A according to the present invention is configured by the horizontal grooves 2 and 2, the vertical grooves 3 and 3 of the electronic device main body 1 described above, the protrusions 6 and 6 of the bracket 5, and the slide members 8 and 8. ing.

Below, the detailed structure of the said slide members 8 and 8 is demonstrated with reference to FIG. 4 which illustrated one slide member 8 and a part of bracket 5 of the vicinity.
The slide member 8 is provided with two horizontally long slots 81, 81, and screws 82, 82 inserted into the slots 81, 81 are screwed into screw holes provided in the tongue piece 7, thereby The slide members 8 can be fixed to the tongue piece 7 by pressing the periphery of the long holes 81, 81 with the heads of the screws 82, 82.
The shape of the long holes 81, 81 is formed in a key shape, and is formed such that the horizontal hole portions 811, 811 in the horizontal direction in the figure are connected to the vertical hole portions 812, 812 in the vertical direction in the figure. Yes.

As described above, since the elongated holes 81 are formed in a key shape, the state shown in FIG. 4 in which the slide member 8 is slid outward (the slide member 8 and the vertical groove of the electronic device main body 1 are not related). In the combined release state), the protrusions 6 and 6 are inserted into the lateral grooves 2 and 2 of the electronic device main body 1, and the electronic device main body 1 is pushed and slid.
As shown in FIG. 4, the slide member 8 is slid from the outside to the inside as indicated by the arrow 1, and the tip thereof is inserted into the vertical groove 3 of the electronic device main body 1 as shown in FIG. 5. Thereafter, when the electronic device body 1 is slightly dropped downward, the slide member 8 engaged with the “Z” -shaped vertical groove 3 is pushed downward, and the screw 82 is inserted into the vertical hole portion 812 of the long hole 81. It will be in a fitted state and will not shift laterally. By further tightening the screw 82 in this engaged state, the slide member 8 is securely fixed to the bracket 5, so that the electronic device main body 1 is also securely fixed to the bracket 5. Further, by making the vertical groove 3 and the tip of the slide member 8 have a “Z” shape, the vertical groove 3 is regulated in both the vertical direction and the horizontal direction.
The elongated hole 81 and the screw 82 constitute the engagement state fixing means described in the claims.

  In the fixed state as shown in FIG. 5, the weight of the electronic device body 1 is supported mainly by the engagement between the ridges 6 and 6 of the bracket 5 and the lateral grooves 2 and 2 of the electronic device body 1. At this time, since the engaging portion between the ridges 6 and 6 and the lateral grooves 2 and 2 is a long region along the side surface of the electronic device main body 1, the weight of the electronic device main body 1 is widely dispersed and reliably supported. It is done.

Then, by fixing the slide members 8 and 8 to the bracket 5 with the screws 82, the longitudinal grooves 3 and 3 of the electronic device main body 1 are in a state where a force that is pushed inward is applied. There is no problem such as the main body 1 wobbling in the front-rear direction, and the main body 1 can be securely locked.
Since the movement of the electronic device body 1 in the left-right direction is restricted by the slide members 8 on both sides, the wobbling in the horizontal direction is eliminated and the electronic device body 1 can be reliably locked.
As described above, in order to prevent the wobbling of the electronic device main body 1, it is not preferable that the width of the longitudinal grooves 3 and 3 is too large with respect to the thickness of the tips of the slide members 8 and 8, so that it can be taken in and out. A marginal width is preferable.

  The operation of loosening the slide member 8 to a slidable state or locking it to a non-slidable state is only to loosen or tighten the screw 82, and it is not necessary to completely remove the screw 82. There is no worry about losing.

  The longitudinal groove engaging member is not limited to a slide member that translates in the horizontal direction, and is rotated into an engaged state inserted into the longitudinal groove and engaged and a disengaged state pulled out from the longitudinal groove. It is also possible to use a movable rotating plate.

Thus, since the electronic device main body 1 can be reliably fixed to a predetermined mounting position via the bracket 5, the bracket mounting device according to the present invention is not limited to a vehicle-mounted wireless communication device or the like, but can be various devices. It becomes an attachment device suitable for fixing the at a predetermined attachment position.
In particular, in the fixing work and the removing work of the device main body 1, the screw 82 is tightened or loosened, and the sliding members 8 and 8 are slid from the outside to the inside or slid from the inside to the outside. Since only work is required, work such as operating the driver from both sides of the bracket is no longer necessary, and work efficiency and safety are improved even in a narrow space, and the structure is simple. Since the bracket can be securely fixed, it is possible to provide an attachment device that is low in cost and excellent in function.

The present invention is not limited to an electronic device such as an in-vehicle wireless communication device, but can be applied to various devices.
