Description

Movable Leg for the Collapsible Table

The present invention relates to a folding table used to expand or fold a board, and more particularly, to a movable support of a folding table that allows the entire table to be moved freely while maintaining the on-time state when the board is opened.

In the past, tables have been used mainly in conference rooms, classrooms, and restaurants so that several people can see their work together.

Such a table is developed in various shapes and structures according to the purpose of use, and one of them is horizontally installed below the plurality of pillars 110 vertically mounted as shown in FIG. 1A and the movable wheels 121 are mounted. The movable support 100 having the supporting members 120, the support hinges 210 are hinged to the upper portion of the pillars 110 and have the locking projection 210a and the folding member 220 is elastically installed. The board 200 which is rotatably installed by the hand, and the intermittent pieces 320 protruding from the upper portions of the pillars 110 to engage or release the engaging protrusions 210a of the board 200 are integrally connected to each other. A folding table composed of operating means 300 having levers 310 is known.

This folding table allows the board 200 to be stretched out horizontally on the pillars 110 of the movable support 100, but after use, the folding table can be folded vertically in front of the pillars 110 of the movable support 100. There was an advantage to keep. In addition, since the folding table can be moved by pushing or pulling by using the moving wheels 121 mounted on the support member 120 of the movable support 100, the user can conveniently carry and move the movable table. I have the advantage.

In the iron folding table as described above, the movement support 100 has the advantage of carrying or moving the table more conveniently as the moving wheels 121 mounted under the support member 120, but the board 200 When used in unfolded, the movement or shaking occurred.

That is, the movable support 100 of the conventional folding table freely rotates the movable wheels 121 having the integrated locking lever 122 at the lower front and rear sides of the supporting members 120, as shown in FIG. While mounted to move in the rolling motion, when the board 200 is folded and moved to release the moving wheel 121 as a locking lever 122 to move the position while rolling along the floor surface, and the board 200 horizontally In use, the moving wheel 121 was wound as the locking lever 122 to maintain the stop state.

However, since the movable support 100 of the conventional folding table is shown in FIG. 1C, since the movable wheels 121 having the integrated locking lever 122 are built on the supporting member 120 and freely rotated, the board ( Although the moving wheels 121 are locked by the lock lever 122 and cannot move when the fan is unfolded, when the small external force is applied, the moving wheels 121 are arbitrarily rotated so that the entire folding table is moved severely. There was a very unstable problem by shaking.

In addition, when the user wants to operate the locking lever 122 of the moving wheels 121, the user must not only have to take the pain and hassle of bending the waist, but actually the user does not have to take the hassle of bending the moving wheel. There was a problem that the stop function is lost by forcibly manipulating the locking lever 122 of the 121 by the foot.

The present invention is configured so that the actuating link and the elevating members cooperate with each other and support the stopper installed on the elevating member toward the floor with the pillar and the supporting member as a support, so that the stationary state can be reliably maintained when the first board is unfolded and used. Foldable to improve stability by improving the convenience by reducing the user's effort and hassle when operating the second movement or stop, and the third, avoiding excessive operation, greatly increasing the service life The purpose is to provide a movable support for the table.

The board 200 is installed as rotatable, and the intermittent pieces 320 are installed integrally with the hand lever 310 which is installed to rotate toward the locking protrusions 210a inside the upper portions of the pillars 10. By installing the operation means 300, it is illustrated that the board 200 can be folded as the operation means 300.

The pillars 10 have a cross-sectional shape that is hollowed up and down so that a space for installing the operation links 30 is secured.

The lower ends of the pillars 10 are fixed to the support members 20, respectively, and are installed to stand vertically, and form rectangular guide holes 11 to face each other on the upper sides of the pillars, so that the pillars 10 The operating arms 31 of the operating links 30 installed therein are inserted to be exposed to the outside so as to be operated up and down.

Here, it is preferable that the membrane cap 12 is installed on the upper end of the pillars 10 so as to be sealed.

The supporting members 20 are horizontally installed at the lower portions of the pillars 10 and are equipped with moving wheels 21 on the front and rear sides.

In addition, the support members 20 form upper and lower assembly grooves 23 and 24 formed in the recesses with the inner plate 22 interposed therebetween at a rear side, and the pillars are formed in the upper assembly groove 23. The lower end of the 10 is fitted to be assembled, and the lower assembly groove 24 allows the lifting member 40 connected to the lower end of the operation link 30 to be assembled.

In addition, by forming a through hole (22a) to be penetrated through the inner plate 22 of the support member 20, it is to be inserted through the operation link (30).

Accordingly, the operation link 30 is caught by the hook 220a when the operation arm 31 unfolds the board 200 and ascends along the guide hole 11 of the pillar 10, and when the board 200 is folded. It is released from the hook 220a and is installed to descend along the guide hole 11 of the pillar 10 as a restoring force of the restoring spring 32, so as to be operated up and down when the board 200 is folded.

Here, the operating arm 31 of the operating link 30 has a rotating ring 33 installed so as to be freely rotated on the operating arm 31 of the operating link 30, the hook 220a of the board 200 It is desirable to reduce the frictional resistance in contact with the t) so that smooth operation can be achieved.

The elevating member 40 is configured to operate the stopper 50 up and down in cooperation with the operation link 30.

The elevating member 40 is fitted into the lower assembly groove 24 of the support member 20 and hinged and fixed as a fixing pin 42 on the inner lower portion of the fixing hardware 41 assembled to the inner plate 22. The stage is free to flow, and one side end of the elevating member 40 is to be installed to be connected as a connecting pin 43 to the end of the operation link (30).

Therefore, the elevating member 40 is lifted by the operation link 30 which is raised when the board 200 is unfolded so that one end is lifted and the other end is lowered, and the operation link is lowered when the board 200 is folded. One side end is pressed by 30 to operate on the principle of the lever of the other end is raised, so that the stopper 50 is operated to be grounded or spaced apart on the bottom surface.

The stoppers 50 are installed at the other ends of the elevating members 40, respectively, so as to be grounded or spaced apart from the floor by the cooperating operation links 30 and the elevating members 40.

As shown in Fig. 4, the stopper 50 integrally forms a ground ring 52 having excellent grounding force at the end of the fastening rod 51 having a threaded portion with a predetermined length, thereby providing the elevating member 40. It is important to install on the other end to adjust the height up and down. The reason for this is to variably adjust the position of the stopper 50 from the elevating member 40 so as to be flexibly grounded on an uneven bottom surface to maintain a stationary state.

As described above, the movable support of the folding table of the present invention ensures the stationary state when the board is unfolded, and is naturally operated when the board is folded, which is convenient for use, and the user's excessive manipulation. It will have the effect of being able to use semi-permanently without being damaged by avoiding.
