Description

[Detailed Description of the Invention] The present invention relates to a chassis holding device for a portable television or the like, and is an object of the present invention to provide an easy and economical method for reliably temporarily fixing the chassis in a position where the chassis is pulled out during service.

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are holders, respectively, and are fixed to bosses 31 and 32 provided on the cabinet 3.

The holders 1 and 2 have upper plates 111 and 121, respectively, as shown in the sectional view of FIG. Side plates 112, 122, lower plate 11
A sliding part 11.1 having a substantially U-shaped cross section and consisting of 3,123 parts.
2, protrusions 114 and 124 on the bottom surfaces of the rear ends of the lower plates 113 and 123, respectively, and elastic deformable parts 14 and 24 extending in a plate shape from the side plates 112 and 122, and further provided with this deformable part 14. Each of the rear ends of .24 is provided with a wedge-shaped part 15.25 that slopes inwardly and outwardly, and a deformed part 14 is provided approximately midway between the wedge-shaped part 15.25 and the rear end of the sliding part 11.21. The deformed portion 1 protrudes downward from the bottom surface of the lower plates 113, 123 by the same distance as the thickness of the chassis 4 from .24.
4.24 is provided with seats 16 and 26 that protrude perpendicularly from the inner surface thereof.

When holding the chassis 4 in the holders 1 and 2 according to the present invention, the chassis 4 is inserted into the sliding portion 11.21 as shown in FIG. 3, and a back cover (not shown) is inserted from the rear.
By fixing it, backward movement is blocked and maintained.

When inspecting the chassis 4 or replacing parts during service, tuners 51 and 52 are installed at the bottom of the chassis 4 as shown in Figure 5.
Because there are parts such as, it is necessary to pull out the chassis 4. However, in the structure of the present invention, first pull out the chassis 4, and as shown in FIG. Insert the tip of the chassis 4 into the space between the chassis 4 and the openings 41 and 42 on both sides of the chassis 4 until the protrusions 114 and 124 of the holders 1 and 2 are fitted into the holes 41 and 42, and then remove the chassis. Let go of the hand that was supporting 4 or release a similar support.

Then, the chassis 4 pushes the wedge-shaped parts 15.25 outward by its own weight, so that the deformed parts 14.24 are deformed outward, the chassis 4 passes through the slope of the wedge-shaped part 15.25, and the receivers are pushed against the seats 16.25. Listed on 26th.

In this state, the wedge-shaped portion 15.25 returns to its original position,
Since the chassis 4 is located inside the width of the chassis 4, the lower surface of the chassis 4 is held by the seat 16.26, the upper plate is held between the lower plates 113, 123, and the wedge-shaped portion 15.25, and the chassis 4 has protrusions 114 on the front, rear, left and right sides. 124, and is reliably temporarily fixed in a state where it cannot be moved in any direction.

At that time, the chassis 4 is pulled out while it is surrounded by three surfaces: the lower surface of the wedge-shaped portion 15.25, the upper surface of the support seat 16.26, and the lower surface of the lower plates 113 and 123. It is held parallel to the previous chassis 4, which makes it easy to maintain without servicing.

To remove the temporary fixing, as shown in FIG.
By rotating and lifting with the side edges as an axis, the projections 114, 124 and the openings 41, 42 are also disengaged, and the temporary fixing is completely removed.

As mentioned above, the present invention has a structure that allows complete temporary fixing to the rear part of the sliding part 11.21, so it is economical because there is no need to use a separate member for temporary fixing. Moreover,
The deformable portions 14°24 deform due to the weight of the chassis 4, making temporary fixing easy and easy to remove.
The chassis 4 is sandwiched between the wedge-shaped portions 15, 25 and the lower plate, and the protrusions 114, 124 restrict movement in the front, back, left and right directions, making it possible to securely temporarily fasten the chassis 4, which is very practical.

Although the present invention has been described as a holding structure for a chassis, it can also simply be used as a holding structure for a printed circuit board unit.

Claims (1)

[Scope of utility model registration request] The structure is such that holders each having a sliding part with a substantially U-shaped cross section are fixed to the cabinet facing each other, and the chassis is inserted and held between them, and a protrusion 1 is provided on the bottom of each sliding part.
14, 124, elastic deformable portions 14, 24 extending from the side plates 112, 122, wedge-shaped portions 15.25 each having an inward slope at the rear end thereof, and furthermore, this wedge-shaped portion 15.25 and the above-mentioned sliding portion. There is a seat 16 approximately halfway between the rear end of the moving part.
26, when the chassis is pulled out using the holder, the tip of the chassis is inserted between the bottom surface of the sliding part and the seat 16. The drilled holes are fitted into the protrusions 114 and 124, respectively, and the chassis is passed between the catch seat 16.26 and the wedge-shaped portion 15.25 to connect the chassis before being pulled out. Chassis holding device that can temporarily hold the chassis in a parallel state.
