Description

[Detailed description of the invention] This invention is used in television receivers, etc., and is divided into a front frame and a rear frame, and a handhold body having a handhold opening is provided on one side of the divided joint edge, and the other side is provided with a handhold body having a handhold opening. The present invention relates to a cabinet provided with a palm reading hole corresponding to a hand opening, and particularly relates to a combination structure of a hand holding body and a hand opening.

Conventionally, this type of cabinet has the advantage that the number of parts and the number of assembly steps can be reduced because the handle body can be molded integrally with the cabinet frame.

However, the connection is difficult as shown in FIG.
Since it was a so-called insertion connection in which the opening 12 of the handhold body 11 was inserted into the handle body, the dimensional accuracy between the insertion connection parts was required to be good, and if the accuracy was poor, it would be impossible to insert them into each other. If the mold is inserted with force, it will break, and if the mold is made more precise, it will be costly to manufacture and maintain the mold.

Also, if a force in a direction perpendicular to the insertion direction is applied to the cabinet during the so-called insertion connection in which the opening 12 of the handhold body 11 is inserted into the handhold hole 10, the handhold hole 10 will be inserted into the handhold hole 10. There is a drawback that the hand hole 10 is damaged due to the application of a so-called twisting force that causes expansion.

In order to easily assemble or separate one side of the cabinet from the other, when a part of the tip of the handhold body 11 is inserted into the handhold hole 10, the force in the insertion direction is applied. This is due to the fact that it is often performed while moving so as to apply a force in a direction perpendicular to the insertion direction.

This is also due to the fact that the direction of insertion is not clear.

This proposal was proposed in consideration of the above points, and it is possible to create a so-called joint connection in which the opening surface of the handhold opening of the handhold body contacts the inner surface of the handhold hole, without inserting the handhold body into the handhold hole. It is characterized by the fact that

An embodiment of the present invention will be described below along with the details.

Figures 1 to 5 show an embodiment of the present invention. Figure 1 is a partial perspective view of the front frame 21 and rear frame 22 when they are separated, Figure 2 is a partial perspective view of their assembly and combination, and Figure 3 is a partial perspective view of the front frame 21 and the rear frame 22. FIG. 4 is a partial perspective view of the right side of FIG. 2, and FIG. 5 is a partial perspective view of the rear frame 22.
A sectional view taken along the line A-A is shown in each figure.

The front frame 21 is box-shaped and is made of synthetic resin and has an opening rim 23 on the rear surface and a cathode ray tube face plate mounting hole 24 on the front surface.

Reference numeral 25 indicates a plurality of hand holes provided on the left and right side surfaces of the front frame 21 that open toward the opening periphery 23, and reference numerals 26 and 27 indicate a plurality of hand holes provided on the inner surface 28 of the upper, lower, left, and right sides of the front frame 21, protruding from the front surface along the direction 28. One of the ribs 26 is provided in a portion that does not have the hand hole 25, and the opening periphery 23-! The opening periphery 23 has a slope 30 forming a groove 29 that gradually narrows inward (forward) between the inner surface 28 and the other rib 27.
It is provided at a portion having a hole and stops slightly inward of the peripheral edge 25 of the hand hole, and forms an abutment surface 41 of a seven-run section 34, which will be described later.

The rear frame 22 is box-shaped with an opening periphery 31 on the front.
It is made of synthetic resin.

32 is provided at the opening periphery 31 and is connected to the hand hole 25 of the front frame 21.
This is a stepped portion that fits in contact with the inner surface 28 of the opening periphery other than the portion corresponding to the opening periphery. When assembled and connected, it fits in contact with the inner surface 28 of the front frame peripheral edge 23.

This fitting is carried out more positively as the stepped portion 32 enters the groove 29 formed by the rib 26 and is pressed toward the inner surface 28 by the slope 30.

Reference numeral 33 denotes a hand grip body that is integrally molded and protrudes from the left and right side surfaces of the rear frame opening periphery 31, and is located at a portion corresponding to the hand hole 25 of the front frame 21, and is a flange portion that projects from the rear frame side surface toward the front frame. 34, a raised portion 35 extending approximately half way from the inner surface of the flange portion 34 to the inner surface of the rear frame side surface, and a rear frame portion provided inside the raised portion 35 and including half of the outer surface 36 of the flange portion 34. It consists of a hand opening 37 that opens on the outer surface of the side surface.

When the front frame 21 and the rear frame 22 are assembled and connected as described above, the outer surface 36 of the flange portion 34 is connected to the hand hole 2 of the front frame 21.
5 inner surface 40. In other words, the handle body 33 is not inserted into the handle hole 25 (particularly in FIG. 5).

The hand hole 25 is closed from its inner surface 40 by the flange portion 34 .

Therefore, the shape of the flange portion 34 is such that its outer side is larger than the hand hole 25 by a predetermined amount.

Then, even if the dimensions of the hand hole 250 change, the outer surface 36 of the flange portion 34 may be formed to a size that takes into account the amount of change.

The light frame end face of the flange portion 34 abuts against the rear frame end face 41 of the lip 27.

Reference numeral 43 denotes a stepped surface that occurs at the connecting portion between the flange portion 34 of the rear frame 22 and the opening periphery 31, and a relief portion 42 for the stepped surface 43 is provided at the connecting portion between the front frame 21.9 hand hole 25 and the opening periphery 23. It is provided as necessary.

Half of the handhold opening 37 of the handhold body 33 passes through the front frame handhold hole 25, and the other half is directly exposed on the side surface of the rear frame, so that the cabinet can be supported by inserting fingers there.

FIG. 6 shows another embodiment of the present invention, which differs from FIG. 1 in that the hand hole 25 of the front frame 21 is shaped to cover the entire circumference of the hand hole 37.

FIG. 7 shows another embodiment of the present invention, in which the stepped portion 32 of the rear frame 22 and the outer surface 36 of the flange portion of the handhold body 33 are connected to the outer surface 4 of the rear frame.
3 to the inside by the thickness of the opening periphery 23 of the front frame 21.

In this case, if the handhold opening 37 is made approximately the same as the handhold hole 25,
The hole (b) consisting of the hand hole 25 and the hand hole 37 are connected on the outer surface to form an integral shape, which makes the appearance even better.

As described above, according to the present invention, the cabinet is constituted by the frames 21 and 22 divided into at least two parts, and the handhold body 33 having the handhold opening 37 is provided on one side 31 of the joint edges of the two parts, and the handhold body 33 having the handhold opening 37 is provided on the other side 23. Since the hand hole 25 is provided in which the inner surface 40 is in contact with the opening surface 36 of the hand hole 37, the hand hole 25 and the hand grip body 33 are not insertedly connected but are connected jointly. The dimensional accuracy of the handhold body 33 may be low, making mold production and assembly operations easy and inexpensive.

In particular, if the opening surface 36 is the flange portion 34, the accuracy error can be easily absorbed by the flange surface.

Furthermore, the handhold hole 25 and the handhold body 33 are not insertedly connected but are jointly connected, and when they are connected (assembled) or separated, there is a force in the direction of the connection or separation as well as a force in a direction perpendicular to that direction. Even if the hand holding hole 25 or the hand holding body 33 is
This has a practical effect in that no force is applied that would cause the two parts to open each other in the hand hole 25, and damage to each other can be eliminated.
