Description

[Detailed description of the invention] This invention relates to a cord-lockable support leg that is installed at the bottom of the housing of an electrical device, and allows cords of different thickness to be reliably locked with one type of support leg. The purpose is to

A conventional support leg for electrical equipment will be explained using FIGS. 1 and 2.

FIG. 1 is a perspective view of a support leg of a conventional electrical device, and FIG. 2 is a perspective view of an electrical device equipped with the support leg.

In the figure, reference numeral 1 denotes a support leg made of elastic plastic, rubber, etc., and provided with three grooves 6 for winding a power cord 4. A locking protrusion 2 is provided.

Conventionally, the support legs 1 configured as described above are arranged at the four corners of the bottom surface of the housing 3 of an electrical device, as shown in FIG. 2, and the unnecessary power cord 4 is connected when the electrical device is not in use. The power cord 4 is wound alternately around the grooves 6 of the four supporting legs 1, and the vicinity of the end of the power cord 4 is sandwiched between the protrusion 2 and the side wall facing the protrusion 2, thereby locking the power cord.

However, the support legs as described above have a drawback in that cords of different thicknesses cannot be reliably locked with one type of support leg.

The present invention eliminates these drawbacks and provides a support leg for electrical equipment that can reliably lock cords of different thicknesses with one type of support leg.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5.

Figure 3 shows a support leg for an electrical device which is an embodiment of the present invention, in which A is a plan view of the same and B is a view of the support leg.

d is a side view seen from the same direction, e is a sectional view of the A-A section, Fig. 4 is a perspective view of the electrical equipment with the support legs arranged at four locations on the housing, and Fig. 5 1 shows an electrical device in which the same support legs are disposed at two places on the housing, and FIG. 1A is a perspective view of the same, and FIG.

In the figure, the support leg 20 is made of elastic plastic, rubber, etc., and has a U for winding the power cord.
A support leg with three grooves 7°8.9 having a letter-shaped cross section, a pedestal part 10 with an anti-slip groove 10', a groove? , 8.9
Partition wall separating 11.12 Attachment part 13 to the electrical equipment casing
A first protrusion 14 for locking a thick cord is provided on the side wall of the groove 7 on the pedestal 10 side, and a second protrusion 14 for locking a thin cord is provided on a stepped portion 16 formed on the side wall. A protrusion 15 is provided.

Next, we will explain how to lock the cord of an electrical device equipped with support legs configured as described above using a small book of support legs arranged at the four corners of the bottom of the electronic device housing 30, as shown in FIG. 20 each R9
, 8 and 7 in turn.

Now, consider the case where power cord 4 is thick.

The first protrusion 1 connects the vicinity of the end of the power cord 4 wound around each support leg 20 to the bottom of the structure 7 of the support leg 20 located in the vicinity.
4, the power cord 4 or the corner wall 11 is elastically deformed, and the cord is locked.

Locking at this time is performed by the first protrusion 14 and also at the second protrusion 15 by pushing and bending the corner wall 11 outward, thereby fixing the corner wall 11 in the groove 7.

Next, if the power cord 4 is a thin cord, either wrap the power cord 4 around each support leg 20 in the same way as above, or because the power cord 4 is thin, it will not be locked to the first protrusion 14 and will be locked to the second protrusion 14. 15, and the groove width is narrowed by the stepped portion 16, so that even if the power cord 4 is thin, the power cord 4 is pressed between both side walls of the groove 7, and the second protrusion 15 makes it thinner. Keep the cord stable.

As explained above, according to this embodiment, two types of cords having different thicknesses can be reliably locked using one type of support leg.

Further, FIG. 5 is a diagram showing a state in which two of the support legs 20 are disposed on the bottom surface of the casing 31 of the electrical device.

In this case, similarly to the above, power cords 4 of different thicknesses can be reliably wound and locked using one type of support leg 20.

In the above embodiment, the groove for storing the cord in the support leg 20?
, 8.9 have a U-shaped cross-section as shown in Figure 5, so the directions of the wound cords are always parallel to each other, so that the ends of the grooves of the support legs suddenly No excessive force is applied to the power cord when it is bent.

In the above embodiment, one protrusion is provided on the step, but the invention is not limited to this, and if necessary, a plurality of protrusions may be provided at appropriate intervals on the step of the side wall of the groove. This makes it possible to lock three or more types of cords with different thicknesses.

Further, although an example has been shown in which the first protrusion and the second protrusion are provided on the same side wall, the same effect can be obtained even if both protrusions are provided on the side walls facing each other.

As described above, according to the present invention, since a protrusion is provided on the stepped portion of the side wall for a thin cord, even a thin cord can be reliably locked.

As described above, according to the present invention, it is possible to securely hold a plurality of types of cords having different outer diameters using one type of support leg without damaging the cords.
