JPS5910055Y2 - housing legs - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to housing legs.

Conventionally, as shown in FIGS. 1 and 2, in this type of housing leg, a rubber 12 provided at the bottom of a circular cap 11 comes into contact with the installation floor and rotatably engages with this cap 11, thereby securing the housing. By rotating the screw 13 that is screwed into the bottom of the body 1, the housing 1 is removed.
The height was being adjusted.

The overturning of the housing occurs when the outermost leg of the housing serves as a fulcrum, and the housing tilts and the center of gravity of the housing moves outward from a vertical line passing through this fulcrum.

Therefore, the larger the overturning angle θ between the vertical line and the straight line connecting the center of gravity of the casing and the fulcrum, the more difficult it is for the casing to overturn.

In the above-mentioned example, this fall angle θ is small, so the fall prevention effect is small, and the casing has the disadvantage that it easily falls.

Another disadvantage is that it is impossible to increase the diameter of the cap 11 in order to position the fulcrum further outward so as to increase the overturning angle θ because the wheels 2 for moving the housing 1 are close to the legs of the housing. have.

An object of the present invention is to provide a housing leg that allows the installation height of the housing to be adjusted and prevents the housing from falling over.

The housing leg of the present invention has a screw that is screwed into the bottom of the housing and rotates to adjust the height of the housing, and a screw that is rotatably engaged with the screw and directed from the bottom of the screw toward the outside of the housing. The housing includes an arm that contacts the floor with an extended landing surface to prevent the housing from falling over.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a partially sectional side view of an embodiment of the present invention, and FIG. 4 is a schematic perspective view of the casing 1 to which the casing legs shown in FIG. 3 are attached.

The screw 13 is screwed into the bottom of the housing 1.

A shaft 17 at the tip of the screw 13 is freely rotatably fitted into a hole 18 provided in the arm 14, and a convex portion 19 of the screw 13 is placed on the upper surface of the arm 14 via a spacer 16.

A washer 21 fixed to the tip of the shaft 17 with a screw 20
prevents the shaft 17 from being pulled out of the hole 18.

A landing surface a consisting of the lower surface of the rubber 15 fixed to the lower part of the arm 14 extends from the part where the hole 18 is provided to the outside of the casing,
The overturning angle θ of the housing 1 is the angle between the vertical line and the straight line connecting the outer tip of the landing surface a of the arm 14 and the center of gravity of the housing 1
' is larger than the overturning angle θ of the example shown in FIGS. 1 and 2, and the arm 14 prevents the casing 1 from overturning.

Furthermore, the arm 14 is narrow, and when adjusting the installation height of the casing 1 by rotating the screw 13, the spacer 16 easily slips on the protrusion 19 and the arm 14, so the arm 14 does not rotate. It can be attached close to the wheels 2 provided on the body 1.

The present invention has the advantage of being able to adjust the installation height of the casing, preventing the casing from falling over, and being able to be attached to the casing close to the wheels for moving the casing.
