I can.

Meanwhile, the shielding plate 100, the fixing member 200, and the support member 300 may be molded by injecting a thermoplastic plastic into a mold. At this time, unnecessary thick portions are formed to reduce weight and maintain constant strength through weight loss (hollow) and rib molding, thereby reducing cost and reducing weight of parts.

<Operation and principle of operation>

When explaining the operation and operating principle of the support leg for furniture integrated with a cover plate according to an embodiment of the present invention configured as described above will be described.

First, as shown in FIG. 7, in a state in which the tubular protrusion 270 of the fixing member 200 is inserted into the mounting hole G formed in advance in the furniture base plate F, and the upper surface is in close contact with the furniture base plate F. Through the nail hole 280, the screw can be firmly fixed to the furniture base plate (F) by tightening or hitting the screw with a tool such as an electric screwdriver or a hammer.

Thereafter, in a state in which the support member 300 is folded and folded into the storage space 220 of the fixing member 200, that is, in a state where the height is narrowed, the sphere 260 contacts the floor surface and rotates freely, resulting in frictional resistance with the floor surface. It slides smoothly and allows you to move and move furniture more conveniently and easily to the installation position by rolling it out.

Subsequently, after placing the furniture at the installation location, the lower part of the upper shielding plate 110 is folded into the insertion groove 121 of the lower shielding plate 120, and the lower locking part 122 of the lower shielding plate 120 is inserted. The height of the furniture can be adjusted by rotating the adjusting member 400 with a tool such as a screwdriver or a hexagon wrench while being inserted into the lower locking jaw 310 of the support member.

In this process, since the fixing member 200 and the supporting member 300 are not rotated to each other, the bottom surface of the supporting member 300 is in close contact with the bottom surface, and the fixing member 200 and the sphere 260 and the top are covered. The height is widened by raising the plate 110 together, and when the rotation operation of the adjusting member 400 is stopped, frictional interference and coupling force (tightening force) due to screw coupling with the fixing member 200 and the support member 300, respectively, are reduced. Occurs and the fixing member 200 stably maintains a state raised to a constant height with respect to the support member 300, and the upper shielding plate 110 rises to a constant height with respect to the lower shielding plate 120 (111) maintains a state caught in the upper locking jaw (210).

That is, as shown in Fig. 8, in order to adjust the height and level of the furniture in a state in which the support member 300 is in close contact with the floor surface, the adjusting member 400 is loosened using a tool such as a screwdriver or a hexagon wrench. Even if the support member 300 is rotated as a structure that does not rotate due to contact interference with the fixing member 200, only the adjusting member 400 rotates, and in this case, the left screw part 240 of the fixing member 200 and the Due to the structural characteristic of the right screw portion 330 of the support member 300 is screwed to rotate in the opposite direction to the adjustment member 400, the fixing member 200 rises, and at the same time, the adjustment member 400 is the support member 300 ) To rise.

At this time, while the upper locking portion 111 of the upper blocking plate 110 causes contact interference with the upper locking jaw 210 of the fixing member 200, the upper blocking plate 110 interlocks and rises, and at the same time, the lower blocking plate Since 120 is closely supported without being lifted from the bottom surface due to contact interference with the lower locking jaw 310 of the support member 300, the blocking plate 100 is naturally unfolded or folded up and down.

That is, the upper screening plate 110 is simultaneously pushed up or lowered according to the lifting of the fixing member 200, so that the height is naturally variable, and the screening plate 100 for blocking and covering the gap between the furniture base plate F and the floor surface. You can easily adjust the height of ).

Therefore, the installation work of the blanking plate 100 to hide the gap or space between the furniture and the floor surface, and the height adjustment for leveling the furniture are much simpler, easier, and smoother and faster. Because it is easy, the speed, convenience and efficiency of work can be greatly improved.

In addition, when the adjustment member 400 is rotated, the fixing member 200 and the support member 300, the upper shielding plate 110 and the lower shielding plate 120 are interlocked in opposite directions to each other, so that the lifting operation is performed. Its height adjustment range and variable range can be maximized and the speed of operation can be secured.

On the other hand, the present invention is not limited by the above-described embodiments and the accompanying drawings, and can be variously modified and applied in various ways that are not illustrated within the scope not departing from the technical spirit of the present invention. It is obvious to those of ordinary skill in the art that the present invention may be substituted and may be widely applied by changing to other equivalent embodiments.

For example, the present invention is mounted on the underside of various furniture such as sinks, chests of drawers, cabinets, showcases, cabinets, cupboards, bookcases, and display stands to guide the movement of the furniture conveniently and easily, and It is common knowledge in the technical field to which the present invention pertains that the furniture can be supported and supported so as to be spaced apart from the floor at predetermined intervals, and can also be used to block gaps or spaces between the underside of the furniture and the indoor floor surface, and to cover the supporting legs. It is obvious to those who have.

Therefore, the contents related to modification and application of the technical features of the present invention should be interpreted as being included within the spirit and scope of the present invention.
