Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mechanism for attaching legs made of rubber or the like to the lower surface of a housing so that the height thereof can be adjusted.

[Conventional technology]

In the conventional mechanism in which legs made of rubber or the like are attached to the bottom surface of the casing in a height-adjustable manner, an internal thread is cut on the casing side, and a bolt with the leg made of rubber or the like is screwed into the internal thread. The height was adjusted by rotating the rubber legs. Further, in Japanese Utility Model Publication No. 48-28375, a screwed adjuster star is provided near the leg provided at the corner of the bottom surface and is inserted into a hole provided in the bottom surface, and the upper and lower ends are screwed into the threaded portion of the adjuster star. A cabinet is disclosed in which a part of the periphery of the nut whose movement is prevented projects out from the front of the main body, and an L-shaped member is provided on the main body as a member to prevent the nut from moving up and down, and the load of the main body applied to the adjuster is reduced. A configuration in which the L-shaped member is received through the L-shaped member is shown in the embodiment.

[Problem to be solved]

However, in conventional mechanisms such as those disclosed in the above-mentioned Japanese Utility Model Publication No. 48-28375, the legs made of rubber or the like must be rotated as described above, but they cannot be used while the casing is in place. When attempting to adjust the height, a large frictional force is generated between the legs and the mounting surface due to the load of the casing, and the legs must be rotated against that frictional force. There are problems in that a large amount of force is required to rotate the legs and it is difficult to adjust the height.

Alternatively, in order to avoid generating the above-mentioned frictional force, it is necessary to lift the casing and move it away from the mounting surface before rotating the legs made of rubber or the like, which makes height adjustment inconvenient.

Furthermore, when moving the casing, the legs often come into contact with an object and rotate, and this rotation causes a problem in that the height of the casing changes.

In addition to the above-mentioned problems, the method disclosed in the above-mentioned Japanese Utility Model Publication No. 48-28375 also has the following problems.

In other words, if you lift the housing or try to adjust the height by turning the nut with no load on the adjuster, such as when the lower end of the adjuster is floating above the mounting surface, the adjuster will rotate as the nut rotates. Since the nut also rotates, I had the inconvenience of having to turn the nut while stopping the rotation of the adjuster star.

Further, since the load applied to the legs is applied to the L-shaped member for controlling the vertical movement of the nut, it is necessary to pay special attention to the strength of the L-shaped member.

Furthermore, when assembling it into the casing, it is necessary to position the nut before screwing the adjuster, so there is a problem that the assembling workability is poor.

[Means for solving problems]

The present invention has been developed in view of the above problems, and consists of fixing a leg made of rubber or the like to the lower end of the bolt, so that the bolt is screwed into the bolt and at least a part of the outer circumference is closer to the side of the casing. A rotating plate disposed in a protruding position is pressed against the bottom surface of the housing from below with the sliding member interposed therebetween by a biasing means, and the bolt is held by a holding means so as to be movable up and down but not rotatable around the axis of the bolt. We took measures to establish a

[Effect]

In the height adjustable leg according to the present invention, when the rotary plate is rotated, the bolt with the leg body screwed into the rotary plate is held by the holding means so that it can only move up and down and cannot rotate, so it does not rotate. It moves up and down, and the legs made of rubber or the like move up and down, changing the height of the casing.

Furthermore, since at least a portion of the outer peripheral portion of the rotary plate is provided to protrude from the side surface of the housing, the protruding rotary plate can be operated while the housing is installed.

Furthermore, the friction between the housing and the rotating plate is reduced by the sliding member sandwiched between the housing and the rotating plate.

Also, since the load of the main body is applied directly to the height adjustment legs from the bottom of the casing, there is no problem with strength.

Additionally, the height-adjustable legs are integrated and can be assembled from the bottom of the housing.

〔Example〕

An embodiment of the height adjustable leg according to the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of one embodiment of the height-adjustable leg according to the present invention, FIG. 2 is a partially sectional perspective view of the above-mentioned embodiment, and FIG. FIG. 3 is a plan view of an embodiment with an adjustable leg and two regular rubber feet;

As shown in FIGS. 1 and 2, a rubber leg 1 and a bolt 4 are fixed to one end of an arm 3, which itself has elasticity, and the bolt 4 is screwed into a rotary plate 2. Small irregularities are provided all around the outer periphery of the rotating plate 2. Then, the arm 3 is elastically biased upward and the other end of the arm 3 is fixed to the housing 7 with a screw 5. At this time, as shown in FIG. 4, a part of the rotary plate 2 is made to protrude from the side surface of the casing 7, and the arm 3 is fixed. The rotating plate 2 has a Teflon plate 6 for smooth rotation due to the elastic biasing force of the arm 3.
It is pressed against the casing 7 with the two sides in between.

Therefore, when the rotating plate 2 is rotated, since the bolt 4 is non-rotatably attached to the arm 3, the bolt 4 moves up and down and the height of the casing 7 changes.

Therefore, when the rotary plate 2 is rotated when the installation surface is not flat and the casing 7 is inclined, the height of the rubber leg 1 is raised or lowered, correcting the inclination of the casing 7. be able to.

Since a portion of the rotary plate 2 protrudes from the side surface of the casing 7, the height can be adjusted while the casing 7 remains installed.

In addition, when storing, transporting, etc. this housing 7,
It is preferable to turn the rotary plate 2 to set the height to the lowest position, insert a spacer plate between the Teflon plate 6 and the casing 7, and adjust the height to the other legs.

In addition to the above, as shown in FIG.
may be biased upward by a spring 9. At this time,
Both ends of the guide body 10 are loosely inserted into rectangular guide holes 11 formed in the housing 7 to prevent the rubber legs 1 from rotating.

It goes without saying that a plurality of height-adjustable legs according to the present invention may be used as needed.

〔effect〕

In the height-adjustable leg according to the present invention, as described above, when the rotary plate is rotated, the bolt screwed into the rotary plate moves up and down, and the leg body made of rubber or the like moves up and down. This has the effect of allowing the height of the casing to be adjusted smoothly.

Further, since at least a part of the outer circumference of the rotary plate is provided to protrude from the side surface of the housing, the protruding rotary plate can be operated while the housing is installed,
The effect is that the height can be easily adjusted.

Furthermore, since the bolts are held so that they cannot rotate but can only move up and down, the legs will not rotate just by moving the casing, so the height will not change involuntarily.

In addition, the sliding member sandwiched between the casing and the rotating plate reduces the friction between the casing and the rotating plate, resulting in smooth operation even when a load is applied. .

Additionally, the load of the main body is applied directly to the height adjustment legs from the bottom of the casing, resulting in an excellent structure in terms of strength.

Furthermore, since the height adjusting legs are integrated and can be assembled from the bottom surface of the housing, it is possible to improve the workability of assembly.

In particular, since the bolt is held non-rotatably around the axis by the holding means, the bolt will not rotate in conjunction with the rotation of the rotating plate even when no load is applied to the adjuster star, resulting in excellent operability. ing.
