FIG. 4 illustrates the seat frame structure 100 by the folding function inherent in the connection member device 140 to prevent breakage of the seat frame structure 100 attached to the table and minimize the space occupied by the table when the table is not in use or during transportation. ) Is a view folded 90 ° in the right direction, it is possible to use a separate fixing member for continuously maintaining the folded state as described above.

As shown in FIG. 2, the seat frame structure 100 is formed by combining a seat 110, a seat frame 120, and a connection member device 140, and a stopper device on one side of the structure formed as described above. Refers to a structure to which 150 is attached and integrally formed.

The seat frame structure 100 formed as described above is fixedly attached to the center leg of the front surface of the table by a connecting member device 140 that functions as shown in FIG.

The seat frame 120 is a main component of the seat frame structure 100 and is equipped with a function for elastic force and compression absorbing force generated upwards to provide elastic force and compression absorbing force to the seat frame structure 100.

The seat frame 120 provides three types of frame structures and three types of respective embodiments for upward elasticity and compression absorption.

The configuration, function, and method of using the table of the seat frame 120 of the first embodiment by the seat frame 120 of the first type will be described below.

As shown in FIGS. 5 and 6, a seat frame housing 124 is formed to surround the seat frame, and a seat bar 121 and a spring guide bar 123 are formed inside the seat frame housing 124, respectively. The seat bar 121 is divided into a seat bar body 121a and a seat bar neck 121b, which are integrally formed.

The lower end of the seat bar body 121a is formed in a hollow with a lower surface thereof, and a spring mounting chamber 122 is formed in the hollow space portion.

One end of the second spring SS is attached to the inner upper end of the spring mounting chamber 122, and the other end of the second spring SS is attached to the top 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, and the first spring FS is attached to the spring guide bar 123 in a spring mounting chamber 122 formed in a hollow on a lower surface thereof. It is pressed by the seat bar body 121a sliding downward in the inserted state.

In this case, the length of the seat bar 121 is formed to be relatively shorter than the length of the seat frame housing 124 surrounding the outer side so that the seat bar 121 moves up and down within the seat frame housing 124 by a shorter length. It is possible.

The pedestal bark 121b is formed integrally with the pedestal bar body 121a and moves together when the pedestal bar body 121a moves, but the upper end of the pedestal bark 121b protrudes outward from the left frame frame housing 124. It moves vertically up and down in the interval allowed by the frame frame housing 124 in the state.

The upper part of the frame frame housing 124 is formed to be relatively narrower than the bottom, such as a bottleneck, so that when the frame bar 121b moves upward in the frame frame housing 124, the frame is relatively wider than the diameter of the frame frame 121b. The bar body 121a is caught in the upper bottleneck of the base frame housing 124, and the movement thereof is limited.

The compression amount of the first spring FS is determined when a load is applied to the seat bar 121 according to the difference of the spring constant. If the same load is applied, the longer the deflection, the smaller the spring constant. Therefore, select a coil spring with a small spring constant to react sensitively to load changes, and select a coil spring with a large spring constant to respond relatively insensitively to load changes. do.

Compression force applied to the seat bar 121 is by the second spring (SS) mounted to the spring mounting chamber 122 and the first spring (FS) mounted while being wound around the spring guide bar 123 as described above The elastic force is generated by the resistance, and the compressive force applied to the seat bar 121 is absorbed by the elastic force generated as described above.

Therefore, since the compressive force applied to the seat bar 121 is distributed by the first spring FS and the second spring SS, the compression distance is shortened and the restoration distance is shorter than when using one spring. That is, it is possible to absorb the compressive force more smoothly while shortening the up and down vibration than when using a single spring.

By designing the spring constant of the second spring (SS) smaller than the first spring (FS), in the initial stage of the load applied to the seat bar 121, the second spring (SS) having a small spring constant reacts sensitively first When the load is absorbed and the load is increased, the first spring FS and the second spring SS are compressed together so that the load is distributed and then restored when the load is decreased. 110 is integrally attached.

The seat 110 is inserted and used between the buttocks so that the table user can support the weight while standing, the user's weight is supported on the seat 110 through the hip and the first spring (FS) and the second spring ( Compression force is applied to SS).

Pressing the lower position of the seat bar 121 on one side of the seat bar 121 that is in contact with the seat frame housing 124 to the inside, and then lowered, so that the locking projection 150a is inserted so that the rising elastic force does not occur temporarily. The locking groove 151 can be formed.

A stopper device 150 is formed at an outer side of the seat frame housing 124 corresponding to the locking groove 151, and a locking protrusion 150a, a locking projection spring 150b, and a locking protrusion rod are formed in the stopper device. Tubes 150c are each formed, and the one-touch button 150d or the operating lever 150d is selectively formed on the outside of the stopper device to stop the locking protrusion 150a by the operation of the one-touch button or the operating lever. Protruding to the 151 to repeatedly move and fix the vertical bar, 121 in the vertical direction.

The seat 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. 1 and 4. At this time, the support leg in the front part of the table is formed in a slightly recessed position than the legs of the other positions formed in each of the left and right directions, as shown in Figs. ) Is folded when not in use or stored, so as not to deviate from the guideline of the front work table of the table to minimize the space of the table, and to prevent the seat frame structure 100 from being damaged from an external impact.

In this case, as shown in FIGS. 1 and 4, the guideline in the center of the front surface of the table workbench is also formed in a slightly recessed shape corresponding to the support legs in the front portion of the table formed at the recessed position.

A stopper device formed on one side of the frame frame 120 after attaching the frame frame structure 100 to the table and inserting the frame 110 attached to the upper end of the frame frame structure 100 between the buttocks of the user of the table. By operating the elastic force upward by the stopper function of 150, the table user can work the table while standing on the pedestal 110 uplifting the user's weight in the upward direction and the user supports the weight As much as the base 110 is compressed.

As described above, as the seat 110 is compressed, the weight of the user is compressed and absorbed by the seat 110 and the seat frame 120, thereby greatly reducing the weight of the table user.

The table work that is standing up works when the user stands with the waist bent forward.In this case, even a healthy user may experience pain in the lower back or knee when working on the table for a long time. I can't work with a table.

The table of the present invention attaches to the support frame part in the middle of the front of the table to support and support the weight of the user while using the table while using the table, so those who do not have a good waist or knee can work the table, normal Users can work on the table for a long time without pain in the lower back or knees.

When the table work is finished, the user presses the seat 110 down downward using his weight to lower the position of the seat 110 and the stuffer of the stopper device 150 formed on one side of the seat frame 120. By operating the operation lever (150d) the lifting of the base 110 is temporarily stopped, the elastic force is stopped.

The left frame structure 100 is stopped as described above is rotated 90 ° in the right direction by the folding function formed in the connecting member device 140 to minimize the space when the table is not used, to prevent damage during movement or storage.

When the work starts again, the seat 110, which is pressed or pulled by the button or the operating lever of the stopper formed on one side of the seat frame 120 as described above, is raised, and the elastic force is generated again.

The configuration and function of the frame frame 120 of the second embodiment by the frame frame 120 of the second type will be described below.

As shown in FIGS. 7 and 8, the hydraulic oil cylinder 250 is formed outside, and the cylinder rod 260 and the spring guide bar 264 are formed inside the hydraulic oil cylinder 250, respectively, and the cylinder rod ( 260 is divided into a cylinder rod body 260a and a cylinder rod neck 260b to be integrally formed.

The hydraulic oil cylinder 250 is divided into an upper portion and a lower portion around the cylinder rod body 260a, and a second hydraulic oil cylinder 250b is formed at an upper portion thereof, and a first hydraulic oil cylinder 250a is formed at the lower portion thereof.

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

One end of the second spring SS is attached to the inner upper end of the spring mounting chamber 263, and the other end of the second spring SS is attached to the top portion 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, the cylinder rod body sliding downward in the state in which the spring guide bar 264 is inserted into the spring mounting chamber 263 formed in the lower surface portion 260a, the second spring (SS) is also pressed together by a spring guide bar 264 inserted into the spring mounting chamber (263).

A hydraulic oil inlet 252 is formed to inject hydraulic oil to an outer side of the upper end of the hydraulic oil cylinder.

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

The cylinder rod neck 260b is formed integrally 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 out of the hydraulic oil cylinder 250. Move vertically up and down.

The upper portion of the hydraulic oil cylinder 250 is formed to have a relatively narrow width as a bottleneck than the lower portion so that the cylinder rod neck 260b is relatively wider than the diameter of the cylinder rod neck 260b when the cylinder rod neck 260b moves upward in the hydraulic oil cylinder 250. The rod body 260a is caught by the upper bottleneck of the hydraulic oil cylinder 250, and its movement is limited.

The seat 110 is attached to the seat frame 120 as shown in FIGS. 7 and 8, and the seat 110 of the seat frame structure 100 attached to the table by the connecting member device 140 is a table user. Inserted between the buttocks to absorb the compressive force applied to the seat 110 when the user supports the weight.

By the way, the first embodiment absorbs the weight and compression force of the table user only by the repulsive force of the first spring (FS) and the second spring (SS), but in the second embodiment absorbs the compressive force through the hydraulic fluid compressed in addition to the spring repulsive force Compression absorption is further enhanced.

While the cylinder rod 260 formed inside the hydraulic oil cylinder 250 is compressed by the seat 110, the hydraulic oil of the first hydraulic oil cylinder 250a is pressed by the cylinder rod body 260a, and the first hydraulic oil cylinder 250a is pressed. The hydraulic fluid of) is discharged to the second hydraulic oil cylinder 250b through the hydraulic oil movement hole 262 formed in the cylinder rod body 260a, and the cylinder rod 260 descends, and at the same time, the first spring FS and the second The spring SS is compressed.

When the compressive force applied to the seat 110 disappears, the cylinder rod 260 is raised by the restoring force of the first spring FS and the second spring SS to return to its original position. At this time, the hydraulic oil of the second hydraulic oil cylinder 250b flows back into the first hydraulic oil cylinder 250a.

In this way, whenever the compressive force applied to the seat 110 is instantaneously changed, the hydraulic oil of the first hydraulic cylinder 250a flows into the second hydraulic cylinder 250b, and when the compressive force disappears, the hydraulic oil of the second hydraulic oil cylinder 250b is again. Is introduced into the first hydraulic oil cylinder (250a) restores the base 110 to the original position.

The process of absorbing the compressive force consists of the movement of the compressed hydraulic fluid as well as the first spring (FS) and the second spring (SS). Since the hydraulic fluid must move through the hole, the cylinder load due to the compressive force The sensitivity at which 260 is moved is determined.

That is, when the oil hole 262 is increased, the hydraulic oil moves quickly, so the reaction speed of the cylinder bar 260 is increased, and when the oil hole is reduced, the hydraulic oil moves relatively slowly, so the reaction speed of the cylinder rod 260 is slowed.

However, if the pores are made too large, the base 110 may rise sharply and hit the buttocks of the user of the table, so that the size of the pores for which a moderate rise is maintained is preferable.

In addition, a third type of seat frame 120 may be used that uses the same fluid pressure (working oil) of the spring as in the second embodiment of the seat frame 120 but differs in structure and operation of the detailed structure.
