Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixing mechanism for fixing an object to be fixed, such as a radio, to a fixed object such as an automobile.

[Conventional technology]

BACKGROUND ART Conventionally, in order to fix an object such as a radio to an object to be fixed such as a car, the object to be fixed is fixed to a fixture using several screws, and the fixture is further fixed to the object to be fixed.

Alternatively, a leaf spring is fitted inside the fixture, and the object to be fixed is pushed in while elastically deforming the leaf spring, and the elastic restoring force of the leaf spring fixes the object to the fixture.

Furthermore, Japanese Utility Model Application Publication No. 53-140868 discloses a notch-shaped guide groove in which a plurality of fitting recesses are formed in a fixing member that holds both side surfaces of a fixed member, and a notch-shaped guide groove that traverses the guide groove along the guide groove. A plate-shaped or linear spring is installed as shown in FIG. A locking mechanism configured to do so is disclosed.

[Problem to be solved]

If the object to be fixed is fixed to the fixing device with several screws as described above, each time the object to be fixed is attached or removed, it is necessary to work from the side or bottom of the fixing device using a screwdriver, etc. However, there is a problem in that it is troublesome to attach and detach.

In addition, as mentioned above, the plate spring can be used to hold and hold the fixed object.
When fixed, it can be attached and detached from only one direction, making it easier to attach and detach. However, each time the fixing is done, the outer surface of the fixed object comes into sliding contact with the leaf spring, so the problem is that the outer surface of the fixed object is easily damaged. There is a point.

Furthermore, since the object to be installed is a car etc.
The fixing surface is often inclined, and the wireless device to be fixed is also inclined, which poses problems in terms of appearance and operation.

That is, there is a strong demand for a fixing mechanism that is easy to attach and detach and has an adjustable attachment angle.

Furthermore, in the fixing mechanism of Utility Model Application Publication No. 53-140868, the degree of freedom in tilting the fixed member is limited to the number of fitting recesses provided in the notch guide groove of the fixing member. The problem is that it can't be done. For example, in the fixing mechanism of Utility Model Application Publication No. 53-140868, it is possible to raise and lower the front surface by changing the longitudinal inclination of the fixed member, but it is possible to raise and lower the front surface by changing the longitudinal inclination of the fixed member. It was not suitable for being moved and relocated.

Furthermore, since the latching protrusion protruding from the side surface of the member to be fixed is fitted into the fitting recess and is pressed and fixed by the spring, the latching protrusion may be prevented from being latched due to vibrations or external forces in automobiles, etc. There was a problem that the .

Therefore, the present invention can easily fix the member to be fixed by attaching it from one direction, and
The purpose of this invention is to provide a fixing mechanism that can be fixed by adjusting the slight inclination in front, back, left, right, and up and down positions, and that does not easily come off due to vibration or external force.

[Means for solving problems]

The present invention has been made to solve the above problem, and is a fixing mechanism that fixes both sides of an approximately rectangular parallelepiped-shaped object, such as a radio, to a fixing member that is fixed to an object to be fixed, such as a car. , a gripped member provided upright on both sides of the fixed object, and a U-shaped three-way hole formed in the fixing member in a substantially rectangular shape into which the gripped member can be inserted. A hole consisting of a fixed part consisting of a side and an opening/closing part consisting of a movable piece on one side, and a large number of holes formed on an edge of the movable piece in the closing direction and an edge of the fixed part facing the movable piece. The movable piece is removably inserted from the opening direction into a serrated portion made of small irregularities, a shaft that pivotally supports one end of the movable piece on the fixed member so as to be freely openable and closable, and a through hole provided at the other end of the movable piece, A screw connects the movable piece to the fixed member by screwing into a screw hole provided in the fixed part, and when the movable piece is opened, the movable piece is urged in the fully open direction, When the movable piece is closed, by providing a leaf spring that biases the movable piece in the closing direction, the biasing direction changes between the closing direction and the fully opening direction depending on the position of the movable piece. When a plate spring and the movable piece are configured, and the object to be fixed is to be fixed, the movable piece is moved in the closing direction by tightening the screw to grasp the inserted member to be grasped. When the fixed object is removed, the movable piece is opened by loosening the screw to disconnect the movable piece from the fixed member.

[Effect]

According to this invention having the above configuration, when fixing the object to be fixed, the movable piece is first opened by pulling out the screw from the through hole provided in the movable piece. At this time, the movable piece is urged in the fully open direction by the leaf spring, so it does not close.

Then, the plate-shaped members to be gripped provided on both sides of the member to be fixed are inserted into the holes formed by the three fixed sides of the U-shape of the fixed member.

Next, when the movable piece is closed, this movable piece
Since it is biased in the closing direction by the leaf spring, both edges of the plate-shaped member to be gripped are engaged by the serrations formed on the opposing surfaces of the movable piece and the fixed side opposite thereto. He was stopped and lightly grabbed.

Since the member to be gripped can be hooked and gripped at any position of the serrated portion, the inclination of the member to be fixed can be finely adjusted.

After the member to be fixed is set in the desired direction in this way, the screw that has been pulled out is inserted into the through hole provided at the other end of the movable piece from the opening direction, and the screw hole provided in the fixed member is inserted. When screwed together, the movable piece is connected to the fixed member.

At this time, by tightening the screw, the member to be fixed is strongly held by the movable piece and the opposing fixed side, so that it will not come off due to vibration or external force.

When the object to be fixed is to be removed, the movable piece opens by pulling out the screw from the through hole, so that the object can be easily removed.

These fixed members can be attached and detached only from one direction (the opening direction of the movable piece).

〔Example〕

An embodiment of the fixing mechanism according to the present invention will be described below based on the drawings.

FIG. 1 is a side view of a first embodiment of a fixing mechanism according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a plan view thereof.

As shown in FIG. 1, FIG. 2, FIG. 3, and FIG. The movable pieces 4, 4' with the movable pieces 4, 4' are pivotally fixed by shafts 5, 5' as opening/closing parts. Here, the serrated portions 2, 2', 3, 3' form a gripping means, and the hole 15 into which the gripped member 9, 9' is inserted is formed between the fixed portion 1 and the movable pieces 4, 4. ' and is formed into a substantially rectangular shape.

Leaf springs 14, 14' are arranged to press the end faces of the movable pieces 4, 4' in the direction of the shafts 5, 5'.

As shown in FIG. 1, the movable piece 4 is formed into a substantially rectangular shape, and when the movable piece 4 is closed, the end face A on the short side is pressed by the leaf spring 14, and the end face A on the long side The end face B is configured to be pressed by the plate spring 14 when the movable piece 4 is fully opened. Therefore, the short side A of the movable piece 4
The biasing direction of the movable piece 4 changes to either the fully open direction or the closed direction when the corner C between the long side B and the long side B comes into contact with the leaf spring 14. . Moreover, the short side end surface A
is in contact with the leaf spring 4 at an angle even in the fully closed state, so a sufficient biasing force can be obtained even in the fully closed state. The same applies to the movable piece 4' and the leaf spring 14'.

In the closed state, the movable pieces 4, 4'
The movable pieces 4, 4' are fixed to the fixed part 1 by screwing the screws 10, 10' loosely inserted into the screw holes 11, 11' formed in the front part of the fixed part 1. can.

Then, on both sides of the in-vehicle radio device 6 as an object to be fixed, the saw-toothed portions 2, 2', 3,
Gripped members 9, 9' are provided to be grasped by 3'.

Here, the fixing part 1 is fixed with screws 13 to, for example, an inclined surface of a console box 12 of an automobile as a fixing object.

First, when the movable pieces 4, 4' of the fixed part 1 are opened,
The elastic biasing force of the plate springs 14, 14' causes the movable pieces 4,
By acting on the end surface B on the long side of 4', the movable pieces 4, 4' are held in an open state.
The vehicle-mounted radio device 6 can be inserted from the front even with one hand.

Next, when the movable pieces 4, 4' are closed, the elastic biasing force of the plate springs 14, 14' is applied to the movable pieces 4, 4'.
4', the gripped members 9, 9' of the in-vehicle radio 6 are attached to the serrated parts 2, 2', 3, 3' of the fixed part 1. It is roughly positioned, and is securely gripped and fixed by tightening the screws 10, 10'.

For example, at this time, if the mounting surface of the fixing part 1 is inclined downward to the right as shown in FIG. , 2' and the movable piece 4,
4', the serrated portions 3, 3' and the grasped member 9,
9' is determined and the movable pieces 4, 4' are closed, the abutting parts 7, 8 of the grasped member 9 abut near the upper ends of the serrated parts 2, 3, Since the abutting portions 7', 8' abut near the lower ends of the serrated portions 2', 3', the in-vehicle radio 6 is fixed horizontally.

Further, for example, the mounting surface of the fixing part 1 may be the fifth
When the in-vehicle radio 6 is tilted upward as shown in the figure, the fixing part 1 is placed in a horizontal position.
The contact positions of the serrated portions 2, 2' of the movable pieces 4, 4' and the serrated portions 3, 3' of the movable pieces 4, 4' and the grasped members 9, 9' are determined. 4' is closed, the contact parts 7, 7' of the grasped members 9, 9' contact near the upper ends of the sawtooth parts 2, 2', and the contact parts 8, 8' contact the sawtooth parts 2, 2'. Since it abuts near the lower ends of the shaped portions 3, 3', the vehicle-mounted radio 6 is fixed horizontally. At this time, since the gripped members 9, 9' are located diagonally with respect to the serrated portions 2, 2', 3, 3', the gripping force is slightly loosened, but the screws 10, By tightening 10', it can be gripped firmly enough.

For example, even if the mounting surface of the fixing part 1 is slightly inclined from the vertical plane, the gripped members 9, 9' and the sawtooth parts 2, 2', 3 of the fixing part 1 can be , 3', the in-vehicle radio 6 can be vertically mounted and fixed by adjusting the abutment position with the mounts 3' and 3'.

In this way, even if the mounting surface is somewhat inclined, the mounting angle of the in-vehicle radio device or the like can be arbitrarily adjusted and the vehicle-mounted radio set or the like can be mounted and fixed horizontally or vertically.

As described above, the gripping means may be formed of wave-shaped small unevenness in addition to the sawtooth-like small unevenness, and it goes without saying that similar small unevenness may be provided on the side of the member to be gripped. Further, the member to be gripped may be a cylindrical body having small irregularities formed on its surface, other than a plate-like body. In either case, the member to be gripped can be gripped at multiple positions.

Further, the opening/closing part may be hooked onto a fixing member, and the opening direction may be downward. In either case, the object to be fixed can be attached or detached only from the direction in which the opening/closing section is opened.

[Effect of idea]

According to the fixing mechanism according to the present invention, the grasping means provided on the fixing member can grasp the member provided on the fixed object at multiple positions, so The inclination and vertical position can be adjusted and fixed, and even if the surface to be fixed is slightly inclined, the mounting angle of the fixed object can be adjusted and the fixed object can be mounted at the optimal angle, such as horizontally or vertically. be.

Further, since a part of the gripping means is provided with an opening/closing part, the member to be gripped of the object to be fixed can be inserted and removed from the opening/closing part, thereby facilitating attachment and detachment of the object to be fixed. effective.

By tightening the screw that connects the opening/closing part to the fixing part, the member to be fixed can be strongly gripped, so that it is possible to reliably prevent the member to be fixed from falling off due to vibration or external force. It will be done.

In addition, since the leaf spring and the movable piece are configured so that the biasing direction changes between the closing direction and the fully opening direction depending on the position of the movable piece, the screw can be pulled out from the through hole provided in the movable piece to open the movable piece. When this happens, the movable piece is urged in the fully open direction by the leaf spring, so it will not close, and there is no need to support the movable piece with one hand, making it easy to attach and detach the fixed member.

Furthermore, when the movable piece is closed, the movable piece is biased in the closing direction by the leaf spring, so that the movable piece and the fixed side facing the movable piece hold the plate-shaped grasped member. Both edges of the fixing member can be easily grasped, there is no need to support the fixing member with one hand, and the fixing member can be easily attached and detached, and its delicate tilt in the front, rear, left, and right directions and vertical position can be easily adjusted.
