Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cord holding device that is most suitable for use when pulling out a power cord from the bottom of a cabinet, for example, in a portable television receiver.

When the power cord is pulled out from the bottom of the cabinet as described above, the power cord is routed through the bottom of the cabinet to the rear of the cabinet in order to connect the plug at the other end to the power outlet.

In this case, the power cord has the drawback that the load of the cabinet is applied to the bottom of the cabinet and the cabinet becomes unstable.

The first object of the present invention is to provide a cord extraction device free from such drawbacks.

A second object of the present invention is to provide a cord extracting device with a simple structure, which is easy to insert and attach, and will not be unnecessarily removed.

The present invention will be explained below according to the drawings.

FIG. 1 is a partial perspective view of the bottom of a television receiver cabinet 10, FIG. 2 is a plan view of the groove shown in FIG. 1, and FIG. 3 is a sectional view taken along line A--A in FIG.

The cabinet 10 is divided into two parts, a front part 11 and a rear part 12, which form a hexagonal shape when combined.

Cabinet 10Lri is made of synthetic resin such as polypropylene, and its dividing surface 16 is the cabinet bottom surface 1 formed by the bottom surface 13 of the front surface section 11 and the bottom surface 14 of the rear surface section 12.
It is approximately the center part of 5.

The front bottom surface 13 has a central portion 1γ that protrudes toward the rear surface 12, and concave grooves 18, 19, 20 are formed at the edges of the portion 1γ.
has.

Reference numeral 21 denotes a groove, which is provided on the bottom surface 13 of the front part and extends toward the front along the groove 20.

The bottom surface 22 of this groove 21 has a hole 23, and this hole 23
The power cord 24 is pulled out from.

A bushing is interposed between the hole 23 and the cord 24.

The hole 23 is opened in the dividing surface 16, so that the bushing or the cord 24 can be easily inserted into the hole 23.

The rear bottom surface 12 has a recess 25 in the center, into which the front protrusion 17 can be inserted.

The edges 26, 27, 28 of the recess 25 can be inserted into the grooves 18, 19, 20 of the front protrusion 17, respectively.

Reference numeral 29 denotes a groove, which is provided on the bottom surface 14 of the rear surface portion and extends toward the rear surface along the edge 28.

The groove 29 faces the front groove 21.

The opening of this groove 29 has both sides 31 and 3 in its longitudinal direction.
Locking pieces 30, 30, . . . are provided alternately (alternately) protruding from 2.

This locking piece 30Vi is formed integrally with the bottom surface 14.

Each locking piece 30 extends from both sides 31° 32 at approximately the center 1 of the groove 29.

Therefore, at the opening of the groove 29, opening grooves 33 are formed which extend in a zigzag shape and are alternately biased toward both sides 31 and 32.

This opening groove 33Fi has approximately half the width of both sides 31 and 32.

Of the locking pieces 30, tongue pieces 35, 35 projecting into the opening groove 33 are integrally formed on both ends of the bottom surface 14 (on the dividing surface 16 side and the rear surface 34 side).

Each tongue piece 35 (I-i) has one end connected to the locking piece 30 via a thin hinge part 36, and the other end connected to both sides 31 of the groove 29.
．． It extends to one side of 32.

Each tongue piece 35 is normally biased so as to extend substantially parallel to the locking piece 30 as shown by the solid line in FIG.

When each tongue piece 35Fi is pressed in the direction of the arrow 37 in FIG. .

When the pressing force in the direction of arrow 37 is released from each tongue piece 35,
The restoring force of the hinge portion 36 returns it to the solid line state in FIG. 3 again.

A bending restriction piece 38 is projected outward from the hinge portion 36 and is buttoned, and this restriction piece 38 faces the end surface 39 of the locking piece 30.

This restriction piece 38 restricts (restricts) the tongue piece 35 from bending from the hinge part 36 in the direction opposite to the arrow 3T by colliding with the end surface 39.
It is something to do.

Main parts such as a cathode ray tube, a chassis, and a printed board are assembled inside the front section 11.

One end of the power cord 24 is connected to a power supply section inside the front section 11 and is led out to the bottom surface 13 through the hole 23.

Next, the rear section 12 is assembled in the direction of arrow 40. At this time, the edges 27 and 28 are inserted into the grooves 19 and 20, and the edge 26
is inserted into the groove 18.

A predetermined number of screws or the like are inserted into the other dividing surfaces 16 and fixed.

Then, the power cord 24 is pulled out along the zigzag opening groove 33 toward the rear surface 34 side, and is inserted into the groove 29 using the opening groove 33.

When inserted, the tongue piece 35Vi is easily bent inward from the hinge part 36, allowing insertion of the power cord 24.

In this manner, the tongue pieces 35 at both ends of the power cord 24 once inserted into the groove 29 close the opening groove 33 and are prevented from being pulled out to the outside of the bottom surface.

Especially when tension is applied to the power cord 24, the groove 29
Although the power cord 24 tries to be pulled out from the opening groove 33 at both ends, the tongue piece 35 prevents it from bending outward as the bending regulating piece 38 abuts against the locking piece end face 39. This can prevent it from coming out.

Further, since the opening groove 33 has a zigzag shape in the middle of the groove 29, it is possible to prevent the power cord 24 from being pulled out.

The width of the opening groove 33 is such that the power cord 24 can be inserted therethrough.
It is preferable that it be as small as possible.

Although the tongue piece 35 is provided on the locking piece 30, it may be provided on the side surface 31 or 32 of the groove 29 that the locking piece 30 faces.

It may also be provided on the intermediate locking piece 30.

When pulling out the power cord 24 from the groove 29, use the tongue piece 3.
Using the elastic deformation of step 5, move the tongue piece 35 with arrow 37 with some force.
The power cord 24 can be bent in the opposite direction so that the power cord 24 can be pulled out.

As described above, according to the present invention, since the opening groove 33 has a zigzag shape, the cord 24 can be easily inserted through the groove 29, and once inserted, it can be difficult to remove.

Since the opening groove 33 is provided with a tongue piece 35 that is easy to bend inward and difficult to bend outward, this makes it easier for the cord to
4 can be easily inserted and more difficult to remove.

Further, the structure can be integrally formed with the casing as in the embodiment, and has the advantage of being simple and inexpensive.
