FIG. 3 is a view of the left, right, and right frame connecting members 140, which are disassembled from the left and right frame structure 100 separated from the table. FIG. 4 is a perspective view illustrating a state in which the seat frame structure 100 (FIG. 4) is folded by a folding function built in the seat frame connection member 140 in order to prevent breakage of the seat frame structure 100 attached to the table during transportation, 100 is folded in the right direction by 90 °, and a separate fixing member for continuously holding the folded state as described above can be used.

As shown in FIG. 2, the left and right frame structures 100 and 120 are integrally formed with the left and right frame frames 120 and 140, respectively. BOX 150 is attached to a structure formed integrally.

The left and right frame structure 100 formed as described above is fixedly attached to the legs of the front of the table by a leg frame connecting member 140 having a connecting function as shown in FIG.

The seat frame 120 is a main constituent body of the seat frame structure 100 and is provided with an elastic force and a function for compressing and absorbing force generated upwardly to provide an elastic force and a compressive absorbing force to the seat frame structure 100.

The sole frame 120 provides three types of frame structures for upwardly-generated elastic force and compressive absorbing force, and three types of respective embodiments thereof.

The configuration and functions of the seat frame 120 of the first embodiment of the first type of seat frame 120 and the method of using the table will be described as follows.

5 and 6, a left-side bar 121 and a spring guide bar 123 are formed inside the left-side frame housing 124, The left-side bar 121 is integrally formed by a left-side bar body 121a and a left-side barb 121b.

The lower end of the seat bar body 121a is formed as a bottom hollow and a spring mounting chamber 122 is formed in the hollow space portion.

One end of the second spring SS is attached to the upper end portion of the spring mounting chamber 122 and the other end is attached to the top portion of the spring guide bar 123 inserted into the spring mounting chamber 122.

The first spring FS is attached to the spring guide bar 123 while being wound on the spring guide bar 123. The first spring FS is inserted into the spring mounting chamber 122 formed in a hollow portion on the lower face of the spring guide bar 123, And is pressed by a left-side bar body 121a which slides downward in the inserted state.

At this time, the length of the left-side bar 121 is relatively shorter than the length of the left-side frame housing 124 that surrounds the outside, so that the left-side bar 121 moves up and down in the left- It is possible.

The left leg barb 121b is integrally formed with the left leg bar body 121a so that the left leg barb 121b moves together when the left bar bar body 121a moves and part of the upper end of the left barb 121b protrudes outside the left leg frame housing 124 And moves vertically up and down in a section allowed by the left and right frame frame housings 124. [

The upper portion of the left frame housing 124 is formed to have a relatively narrow width as a bottleneck than the lower portion so that when the left standing bar 121b moves upward in the left frame housing 124, The bar body 121a is caught by the upper bottleneck portion of the left frame housing 124 and its movement is restricted.

The amount of compression of the first spring (FS) is determined when a load is applied to the seating bar (121) according to the difference in spring constant. If the same load is applied, the spring constant becomes smaller as the deflection amount becomes longer. Therefore, in order to react sensitively to the load change, a coil spring having a small spring constant is selected, and a coil spring having a large spring constant is selected do.

The compressive force applied to the seat bar 121 is transmitted to the spring seat 122 by the second spring SS mounted on the spring mounting chamber 122 and the first spring FS mounted on the spring guide bar 123 An elastic force is generated by the resisting force, and the compressive force applied to the seat bar 121 is absorbed by the elastic force generated as described above.

Accordingly, since the compression force applied to the seating bar 121 is dispersed by the first spring FS and the second spring SS, the compression distance is shortened and the restoration distance is also shortened when one spring is used. That is, it is possible to absorb the compressive force more smoothly while shortening the up / down vibration more than when using one spring.

The spring constant of the second spring SS is designed to be smaller than that of the first spring FS so that the second spring SS having a smaller spring constant initially reacts sensitively at the beginning of the load applied to the seat bar 121, When the load is absorbed and the load is increased, the first spring (FS) and the second spring (SS) are compressed together and the load is dispersed. When the load is reduced, the load is restored. 110 are integrally attached.

The weight of the user is supported by the seat 110 through the buttocks, and then the first spring FS and the second spring (not shown) are inserted into the buttocks so as to support the weight of the table, SS).

The position of the seat bar 121 is pressed down on one side surface of the seat bar 121 which is in contact with the seat frame housing 124 on the inner side so as to be lowered and fixed so that the locking protrusion 150a is inserted The engaging groove 151 is formed.

A stopper box 150 is formed at one side of the leg frame housing 124 corresponding to the latching groove 151. A locking projection 150a, a locking projection operating spring 150b, A button 150d and an operation lever 150d are selectively formed on the outside of the BOX so that the latching protrusion 150a is engaged with the latching groove 151 by the operation of the one- So as to move and fix the vertical bar 121 in the vertical and downward directions repeatedly.

The left and right frame structure 100 formed as shown in FIG. 2 is vertically attached to the support legs in the front of the table as shown in FIGS. In this case, the support legs in the front part of the table are formed at a slightly recessed position relative to the legs at other positions formed in the left and right directions as shown in FIGS. 1 and 4, Is not used, or when it is folded at the time of storage, the space of the table is minimized so as not to deviate from the guide line of the front work table of the table so that the seat frame structure 100 is not damaged from external impact.

In this case, as shown in FIGS. 1 and 4, a guide line in the center of the front of the table work table corresponding to the support legs of the front part of the table formed in the recessed position is formed in a slightly recessed shape.

After the left and right frame structures 100 are attached to the table and the left and right legs 110 attached to the upper ends of the left and right frame structures 100 are inserted between the buttocks of the table user, The elastic force is actuated upward by the stopper function of the user 150, so that the table user can perform the table operation while holding the weight of the user in the upward direction, The counterweight 110 is compressed.

As the seat cushion 110 is compressed as described above, the weight of the user is compressed and absorbed by the seat cushion 110 and the seat cushion frame 120, and the weight applied to the knee or waist of the table user is greatly reduced.

In this case, a healthy user may suffer pain in his or her back or knee when working a table for a long time. In case of a normal waist or knee, I can not work on the table.

The table according to the present invention can support the user's body weight by supporting and supporting the weight of the table during the use of the table by attaching the left and right frame structures 100 to the support legs in the middle of the front of the table, Users can also work on the table for a long time without pain in the back or knee.

When the table operation is completed, the user lowers the position of the seat 110 by pushing down the seat 110 downward by using his / her own body weight, and the position of the seat 110 of the stopper BOX 150 The operation lever 150d is actuated to temporarily stop the rise of the platform 110, and the elastic force is stopped.

The left-arm frame structure 100, which has ceased to operate as described above, is rotated 90 degrees to the right by a folding function formed on the left-arm frame connecting member 140 to minimize the space when the table is used, .

When the work is started again, the pushbutton or the operation lever of the stopper formed at one side of the left frame 120 is pressed or pulled to raise the left leg 110, and the elastic force is generated again.

The configuration and function of the second frame 120 of the second embodiment will be described as follows.

A cylinder rod 260 and a spring guide bar 264 are formed inside the cylinder 250 so that the cylinder rod 250 and the cylinder rod 250 are formed as shown in Figures 7 and 8, 260 are integrally formed by a cylinder rod body 260a and a cylinder rod neck 260b.

The operating oil cylinder 250 is divided into an upper portion and a lower portion around the cylinder rod body 260a. A second operating oil cylinder 250b is formed on the upper portion and a first operating oil cylinder 250a is formed on the lower portion.

The lower end of the cylinder rod body 260a is hollow and has a bottom, and a spring mounting chamber 263 is formed in a hollow space. A second spring SS is mounted on the spring mounting chamber.

One end of the second spring SS is attached to the upper end of the spring mounting chamber 263 and the other end is attached to the top of the spring guide bar 264 inserted into the spring mounting chamber 263.

The first spring FS is attached to the spring guide bar 264 while being wound on the cylinder head body 261. A spring guide bar 264 is inserted into the spring mounting chamber 263 formed on the lower surface of the cylinder rod body, The second spring SS is also urged by the spring guide bar 264 inserted in the spring mounting chamber 263. [

And a working oil inlet 252 for injecting the working oil is formed on the outer side of the upper end of the operating oil cylinder.

The length of the cylinder rod 260 formed inside the hydraulic cylinder 250 is relatively shorter than the length of the hydraulic cylinder 250 so that the cylinder rod 260 moves up and down within the hydraulic cylinder 250 by a short length While sliding is possible.

The cylinder rod neck 260b is integrally formed with the cylinder rod body 260a and moves together with the cylinder rod body 260a but the upper end of the cylinder rod neck 260b is partially protruded outside the cylinder 250 Vertical direction, and downward direction.

The upper portion of the operating oil cylinder 250 is formed to be narrower than the lower portion like a bottle neck so that the cylinder rod neck 260b is moved upward in the operating oil cylinder 250, The rod body 260a is caught by the upper bottleneck portion of the hydraulic cylinder 250 and its movement is restricted.

The leg 110 of the leg frame structure 100 attached to the table by the leg frame connecting member 140 is attached to the leg 110 of the leg frame 110 as shown in Figs. 7 and 8, And is inserted between the user's buttocks to absorb the compressive force applied to the seatbelt 110 when the user supports his or her body weight.

However, in the first embodiment, the body weight and the compressive force of the table user are absorbed only by the repulsive force of the first spring FS and the second spring SS, but in the second embodiment, the compressive force is absorbed The compressive absorption force is further strengthened.

The cylinder rod 260 formed inside the hydraulic cylinder 250 is compressed by the bucket 110 so that the hydraulic fluid of the first hydraulic cylinder 250a is pressed by the cylinder rod body 260a and the hydraulic oil of the first hydraulic cylinder 250a Is discharged through the hydraulic oil transfer hole 262 formed in the cylinder rod body 260a into the second hydraulic cylinder 250b while the cylinder rod 260 descends and simultaneously the first spring FS and the second hydraulic oil The spring SS is compressed.

When the compression force applied to the platform 110 disappears, the restoring force of the first spring FS and the second spring SS causes the cylinder rod 260 to rise and return to the original position. At this time, the operating fluid of the second operating fluid cylinder 250b flows back into the first operating fluid cylinder 250a.

When the compressive force applied to the platform 110 is instantaneously changed, the hydraulic fluid in the first hydraulic cylinder 250a flows into the second hydraulic cylinder 250b. When the compressive force disappears, the hydraulic fluid in the second hydraulic cylinder 250b The first hydraulic cylinder 250a and the second hydraulic cylinder 250a.

The process of absorbing the compressive force is performed not only by the first spring FS and the second spring SS but also by the movement of the compressed hydraulic oil. Since the hydraulic oil must move through the holes, The sensitivity with which the moving object 260 is moved is determined.

That is, when the hole 262 is enlarged, the operating oil moves faster, so that the reaction speed of the cylinder bar 260 is increased. When the hole is made smaller, the operating oil moves relatively slowly, so that the reaction speed of the cylinder rod 260 is slowed down.

However, if the perforation is excessively increased, it is preferable that the size of the perforation is maintained so that a gentle lift can be maintained since the supporter 110 may abruptly rise and hit the buttocks of the user of the table.
