More specifically, the present invention maximizes height and variable range to improve convenience and usability as well as versatility The present invention relates to a pedestrian foot capable of adjusting a height and a height.

BACKGROUND ART [0002] In general, kitchen furniture for sinks, cupboards, etc. are mounted on the bottom of various furniture such as dressers, beds, bookcases, and the like for supporting and supporting the furniture in a spaced-

Such a support leg can be easily adjusted in level when the furniture is installed by employing a structure in which the height can be adjusted usually, and the installation height of the furniture can be adjusted for convenient use.

For example, as shown in FIG. 1 and FIG. 2, a horizontal adjustment device for a furniture disclosed in Korean Utility Model Publication No. 20-0445789 comprises a support body 20, a support member 20 rotatably coupled to the support body 20, A rotating body 30 having a rotating shaft 31 having a male thread 32 in the vertical direction at its center and a rotating body 30 having an upper surface contacting the bottom 2 of the furniture, And a cover member 40 having a thread 42 and an engaging groove 44 into which the upper end of the rotating body 30 is fitted.

Therefore, the height of the furniture can be adjusted while the rotating body 30 is moved up and down with respect to the cover member 40 by the user's operation of rotating the rotary shaft 31. [

However, in order to adjust the height and widen the variable range, the height of the rotatable body 30 is required to be adjusted by adjusting the height of the rotatable body 30 in order to adjust the height of the furniture by simply raising and lowering the rotatable body 30 relative to the cover member 40 In this case, if it is attached to the bottom surface of the furniture, it will protrude so that it may cause troubles in operation when it is transported to a place of installation or the like, and it is easily damaged when receiving external force.

Furthermore, because dead space is not utilized because the height of the rotating body 30 can not be used as a space between the furniture and the floor, the space occupied by the furniture in the room can not be sufficiently utilized as a storage space, There is also a problem.

In the meantime, most of the chests are installed in a manner that the upper part is pushed up with the lower part as an axis, while the upper part of the chairs is placed in an obliquely inclined state. In order to prevent the upper end of the chairs from interfering with the ceiling of the room, It is limited only within a certain range.

As a result, unnecessary dead space is generated between the chandelier and the ceiling, so that not only the appearance is not good but also the occupancy space occupied by the chandelier in the room can not be fully utilized as a storage space, resulting in a limit of space efficiency.

This causes the rotating body 300 to rotate simultaneously with the rotating body 200, The fixed body 100 and the rotating rigid body 300 are raised to a certain height with respect to the supporting body 400 when the rotating body is stopped in this state .

The coupling force between the rotating body 200 and the rotating body 300 is stronger than the coupling force between the rotating body 300 and the supporting body 400 due to the screwed state of the rotating body 200, The frictional force is generated due to the contact interference between the second release bust 320 of the rotating body and the third release bust 430 of the base body, , Whereby the rotating body 200 is rotated and elevated, and the secondary body 100 is lifted secondarily.

7, when the rotating body 200 is rotated in the tightening direction by using a tool such as a screwdriver or a hexagonal wrench, the fixing body 100 and the supporting body 400 are rotated in the tightening direction, The rotating body 200 is first lowered due to the structural property of the rotating body 200 being screwed to the rotating body 300 and the lower body 100 is lowered When the rotation operation is stopped in this state, the fixture 100 is maintained in a lowered state at a constant height with respect to the support member 400. [

If the frictional force and the coupling force due to the contact interference between the rotating body 200 and the rotating body 300 are stronger than the frictional force and the coupling force due to the contact interference between the rotating body 300 and the supporting body 400, As shown in the figure, the rotating rigid body 300 is first rotated and lowered together with the rotating body 200 to descend the fixed body 100.

When the fixed body 100 and the rotating body 200 are lowered to a certain height or less by rotating the rotating body 200 in the tightening direction, contact interference between the bottom surface of the collar 230 of the rotating body and the upper surface of the rotating body The rotating rigid body 300 rotates simultaneously with the rotating body 200. This causes the rotating rigid body 300 to descend due to the structural nature of the rotating body 300 being screwed to the supporting body 400, And the rotating body is stopped in this state, the fixing body 100 and the rotating body 300 are maintained at a predetermined height with respect to the supporting body 400. [

The coupling force due to the contact interference between the rotating body 200 and the rotating body 300 is stronger than the coupling force due to the contact interference between the rotating body 300 and the supporting body 400, When the rotatable rigid body 300 first rotates and descends at a constant height, the bottom of the rotatable rigid body 300 comes into contact with the ground or the bottom surface to generate a frictional force, thereby rotating and descending only the rotatable body 200, So that the fixture 100 is lowered.

Therefore, it is possible to maximize the height adjustment and the variable range, thereby improving the usability and usability of the furniture, as well as improving the versatility and space efficiency.
