Therefore, the rotating foot is locked regardless of whether it is in use or not.

[Industrial application field]

The present invention relates to a foot locking mechanism for preventing fall, which is disposed around the lower end of a device.

In recent years, there has been a trend for various electronic devices to be designed as high as possible and to minimize floor area in order to make them smaller, lighter, and have better space factors. As the instability factor increases, as a measure to prevent the device from tipping over, a tipping prevention foot is provided around the bottom end of the device, and when the device is installed, measures are taken to extend this leg outward to improve stability. However, there is a demand for a locking mechanism for the fall prevention foot that is structured to be locked regardless of whether the fall prevention foot is in use or not.

PRIOR ART

FIG. 3 is a perspective view of a main part illustrating the structure of a conventional fall prevention leg.

In the figure, as a measure to prevent the device 1 equipped with a plurality of buffer members 2 from falling due to earthquakes, etc., the device 1 is
Attach a plurality of fall prevention fittings 3 (one piece is shown in the drawing) to the space provided with the buffer member 2 on the back side of the
It is fixed at

This fall prevention fitting 3 is made by bending a metal, for example, an iron plate into a Z-shape to correspond to the height of the buffer member 2, and providing a long hole 31 at one end, so that it is fixed on the back side of the device 1 when the device 1 is moved. Loosen the fixing screw 4 that is attached, retract it along the bottom of the device 1, and push it inside the device 1. When the device 1 is installed, tighten the fixing screw 4.
This is a structure in which the anti-fall fitting 3 is extended outward from the device 1 by loosening the holder.

[Problem that the invention attempts to solve]

With the structure of the conventional fall-prevention foot described above, when moving or installing the device, it is difficult to work because the fixing screw attached to the back of the device must be loosened and the fall-prevention fittings must be expanded and retracted, which is difficult to work with. There was a problem.

[Means for solving problems]

The present invention is to solve the above problems and provide a locking mechanism for the anti-tip feet which can be operated with one touch without using tools.

That is, the locking mechanism of the foot for preventing the device from falling is structured with a fixing part and a rotating foot that is rotatably screwed onto the device together with the fixing part, and the plane of the fixing part is shaped like a lock. A protrusion is provided at the ends of both sides, a protrusion is provided at the center of the orthogonal sides, the side cross section is also shaped like a lock, and one end of the rotating leg is shaped like a semicircle. A protrusion is formed in the center of the semicircular arc, a slit is formed adjacent to the protrusion to form a spring part, and a shaft hole is formed in the center of the semicircle. This is solved by the formation of

[Effect]

This foot lock mechanism for preventing falls is
The fall prevention foot can be moved 90 degrees with a single touch without the use of tools, providing good workability and locking regardless of whether the fall prevention member is in use or not.

〔Example〕

FIG. 1 is a diagram illustrating an embodiment of the present invention.
Figure a is a front view, b is a plan view showing a cross section of the main part of the rotating foot, Figure 2 is a diagram illustrating an example of implementation of the present invention, figure a is a perspective view, and b is a view seen from arrow A. In the figure, the third
Parts that are equivalent to those in the figure are given the same reference numerals.

In the figure, as a measure to prevent the device 1 equipped with a plurality of buffer members 2 from falling due to earthquakes, etc., the device 1 is
Attach a plurality of fall prevention members 7 (two are shown in the drawing) to the space provided with the buffer members 2 on the back side of the mounting screw 1.
It is screwed so that it can rotate at 0.

This fall prevention member 7 is composed of a fixing part 5 made of a synthetic resin molded product, and a rotating leg part 6 made of synthetic resin that is rotatably screwed to the device 1 together with the fixing part 5. The fixing part 5 has a flat surface shaped like a lock, and has protrusions 51 at the ends of both sides, and a protrusion 52 with a triangular cross section at the center of each side, and the side cross section is also shaped like a key. Attachment hole 5 of the rotating leg part 6 formed in a cutlet (") shape
Drill 3.

Then, one end of the rotating foot 6 is formed into a semicircular shape, and a protrusion 61 having a triangular cross section is formed at the center of the semicircular arc.
A slit 62 is formed adjacent to the projection 61 to form a spring portion 64, and a shaft hole 63 is bored in the center of the semicircle.

The shaft hole 63 of the rotating leg 6 and the mounting hole 53 of the fixing part 5 are aligned as described above, and the mounting screw 10 is inserted into the mounting hole on the back side of the device 1 (not shown) via the washer 8 and the spring washer 9. and screw it rotatably with nut 11.

By having such a configuration, Fig. 1a
When the rotating foot 6 is rotated in the direction of arrow B against the elasticity of the spring 64 as shown in FIG. It jumps over the protrusion 52 of the fixed part 5 and rotates 90 degrees, and also jumps over the protrusion 52 on the other side of the fixed part 5 and stops, and the side surface of the rotating foot part 6 rotates 90 degrees. 51 and is locked, the rotating foot 6 can be easily rotated 90° without using any tools.

Note that in this embodiment, the fixed portion 5 of the rotation prevention member 7
Although synthetic resin has been described as the material of the rotating leg portion 6, it is not limited to synthetic resin, and may be made of iron or other metal materials.

[Effect of idea]

As is clear from the above description, according to the present invention, measures to prevent equipment from falling can be easily implemented, improving the efficiency of equipment installation and relocation work, and being extremely effective in preventing equipment from falling.
