Description

[Detailed explanation of the idea] The present invention relates to a leg that is attached to the bottom of a communication device, etc.

In general, communication devices and the like are sometimes placed at an angle so that the operating surface (front) side is higher than the back side in order to improve operability.

For this purpose, it is desirable to attach legs that are configured to be variable in height to the front side of the device, but conventionally, as shown in Figure 1, legs are attached to the front side of the device at the same height as the legs on the back side. The script body 21 is attached to the mounting surface 22 of the device with a mounting bolt 23, and a separately prepared auxiliary leg 24 is added below it.

In addition, 25 in the figure is a screw for attaching the auxiliary leg 24, and is designed to be screwed into the head of the above-mentioned attachment bolt 23.

However, in the above-mentioned conventional type, a special mounting bolt 23 is required, which increases the cost, and it is inconvenient because the auxiliary leg 24 must be attached and detached each time. There was a risk that all of the screws and screws 25 would be exposed.

The purpose of this invention is to eliminate the drawbacks of the conventional ones mentioned above, and
It is an object of the present invention to provide a leg for a communication device, etc., which does not require any special mounting screws or the like, and whose height can be varied with a one-touch operation.

An embodiment of the present invention will be described based on the drawings from FIG. 2 onwards.

In the figure, 1 indicates the entire leg, and 2 indicates the mounting surface on the bottom of the communication device or the like.

A male member 3 is fixed to the mounting surface and has a substantially cylindrical shape.

Reference numeral 4 denotes a female member having a substantially cylindrical shape with a bottom, which is fitted into the male member 3 and is engaged with the male member 3 so as to be slidable in the vertical direction.

5 is a metal fitting for preventing the female member 4 from being pulled out, as will be described in detail later.

A protruding wall portion 6 having a vertical edge 6a is provided on the outer wall of the male member 3 to face the male member 3, and a stopper portion 6b is left at the tip of the protruding wall portion 6, and the circumference is continuous with the vertical edge 6a. A notch step portion 7 is formed in the direction.

A locking flange 8 whose inner diameter corresponds to the diameter of the male member 3 is protruded from the inner periphery of the opening edge of the female member 4. A corresponding notch 8a is formed, and locking edges 9, 9 are provided in the remaining portion thereof.

Therefore, the inner surfaces 9a, 9a of the locking edges 9, 9 can slide vertically on the outer circumferential surfaces 3a, 3a of the male member 3, and are prevented from being removed due to the presence of the removal prevention fitting 5, which will be described later. In addition, when the female member 4 is pulled out (lowered), the locking edges 9, 9 are located at the entrance of the notch step 7, so the female member 4 has a tip edge of the locking edge 9. It can be rotated until it hits the stopper part 6b.

The removal prevention metal fitting 5 has a substantially plate shape, and has the above-mentioned locking edges 9, 9.
A cutout 10.10 corresponding to the female member 4 is provided.
It can be inserted inside.

This extraction prevention metal fitting 5 is attached to the male member 3 while being fitted into the female member 4, and 11 is a detent hole into which a protrusion 12 protruding from the male member 3 is inserted. It is designed to fit together.

A large hole 13 is drilled in the bottom side of the female member 4, and a screw hole 15. It is fixed to the mounting surface 2 through 16.

17 is a nut of the mounting screw 14.

The mounting angle of the ejecting prevention fitting 5 is such that the cutout portions 10 and 10 are located on the side of the cutout stepped portion 7 of the male member 3, as shown in FIGS. 5 and 6.

Note that the bottom side of the female member 4 may be formed into a cylindrical shape, and the pull-out prevention fitting 5 may be fitted from the bottom side; in this case, the fitting 5 may remain disc-shaped.

Although the outer peripheral surface 3a of the male member 3 and the inner surface 9a of the locking edge 9 of the female member 4 are shown as having a gap in FIG. 6 to clarify the positional relationship, In reality, both are placed closely together as shown in FIG.

Next, to explain an example of operation, FIG. 4 shows a state in which the legs are lowered, but if the legs are to be raised higher, the female member 4 is pulled out.

In this case, since the locking edge 9 is locked with the removal prevention metal fitting 5, the female member 4 will not be removed.

When the female member 4 is pulled out, the locking edge 9 is located at the entrance of the notch step 7, so the female member 4 can be rotated, and in the rotated state, the locking edge 9 is located at the entrance of the notch step 7. 7, the female member 4 can maintain its pulled out state and the legs can be raised higher.

In addition, as shown in FIG. 6, the locking edge 9 is connected to the stopper part 6b.
Even when the locking edge 9 is rotated until it hits the stopper part 6b, the rear end of the locking edge 9 is at the rear end of the notch 10 of the removal prevention fitting 5. Therefore, there is no possibility that the female member 4 will be pulled out.

According to the leg of the present invention for communication devices, etc., there is no need for special mounting bolts, and the female member is locked and the height can be changed by simply pulling out the female member and rotating it in this state. Because of this, the height can be changed with a single touch, and there is no need to attach or detach the auxiliary legs each time, which is the case with conventional models.

Therefore, there is no risk of losing any parts, and since no special parts are required, costs can be reduced.
