[0040] Among the seats placed in bank branches for customers to use, some seats are fixed in front of the counter for stability considerations. This provides better stability, but the seats cannot be moved, which results in insufficient comfort for customers of different body shapes. Therefore, a roller structure can be set at the bottom of the seat so that the position of the seat can be adjusted according to customer needs, but this will result in poor stability of the seat, and the seat may move back and forth when the customer sits on it, generating noise.

[0041] In the chair proposed in the present application, the chair body is arranged on the base, and the vertical rod is connected with the roller and the base, so that the roller can be supported on the base through the vertical rod, and then supported on the chair body. The two ends of the elastic member are in contact with the vertical rod and the base respectively, and the base is subjected to external force and moves toward the roller relative to the vertical rod, so that the height of the base is not higher than the roller, and the base acts on the elastic member to deform the elastic member, so that when the roller contacts the ground, the base can also contact the ground, and the friction between the base and the ground can make the chair of the present application remain in a relatively fixed state with the ground, thereby preventing the seat from easily moving relative to the ground. The contact between the base and the ground can also make the chair body more stable, preventing the user from tilting and falling when sitting on the chair body. When the base is no longer subjected to external force, the base can move back to the roller relative to the vertical rod under the action of the restoring deformation force of the elastic member, so that the height of the base is higher than the roller, so that when the roller contacts the ground, the base does not contact the ground, so that the chair of the present application can be conveniently moved relative to the ground through the roller, so that the position of the seat can be conveniently adjusted to a comfortable position for the customer.

[0042] The present application embodiment proposes a seat, referring to Figures 1 to 4 As shown, the chair comprises a body 100 , a base 200 , a vertical rod 300 , a roller 400 and an elastic member 500 .

[0043] Among them, the chair body 100 is the basic component of the chair of the present application, and the chair body 100 can provide a mounting base for at least part of the other components of the chair. The chair body 100 can be made of metal material, so that the chair body 100 has better structural strength, thereby making the durability and reliability of the chair better. Of course, the chair body 100 can also be made of polymer material, so that the chair has a certain structural strength and is relatively light. A seat surface can be set on the chair body 100, and the user can sit on the seat surface of the chair body 100 when using the chair of the present application.

[0044] The base 200 is disposed at the bottom of the chair body 100. The base 200 can be supported on the chair body 100 by the bottom of the chair body 100. Specifically, the base 200 can be located at the bottom side opposite to the seat surface of the chair body 100. The vertical rod 300 can be vertically disposed at one side of the bottom of the base 200. One end of the vertical rod 300 is connected to the base 200, so that the vertical rod 300 can be supported on the base 200, and further the vertical rod 300 can be supported on the chair body 100. The other end of the vertical rod 300 can be connected to the roller 400, so that the roller 400 and the base 200 can be located at both ends of the vertical rod 300. When the chair of the present application is placed on the ground, the roller 400 can be located on the ground. One end of the vertical rod 300 is movably connected to the base 200, so that the base 200 can move relative to the vertical rod 300. Specifically, the base 200 is configured to move relative to the vertical rod 300 along the axial direction of the vertical rod 300, so that the height of the bottom side of the base 200 is not higher than the roller 400, or the height of the base 200 is higher than the roller 400. That is, the base 200 can move toward the roller 400 or move away from the roller 400 relative to the vertical rod 300. The roller 400 can specifically adopt a universal wheel, so that the seat of the present application can move or rotate in different directions through the roller 400.

[0045] One end of the elastic member 500 is connected to the vertical rod 300, and the other end of the elastic member 500 is connected to the base 200, so that one end of the elastic member 500 can be fixed to the vertical rod 300, and the other end of the elastic member 500 is supported on the base 200. When the base 200 moves along the axial direction of the vertical rod 300, the elastic member 500 will be compressed or stretched accordingly, so that the elastic member 500 can have a first state and a second state, and the elastic member 500 is deformed and has a restoring deformation force.

[0046] When the base 200 moves toward the roller 400 along the axial direction of the upright 300 and rolls on the ground, the base 200 can also move toward the ground. The base 200 can move toward the roller 400 until the height of the bottom side of the base 200 is not higher than the height of the roller 400, so that the bottom side of the base 200 can also move to contact the ground, so that the ground can be supported on the chair body 100 through the base 200, so that the chair body 100 remains stable. Specifically, when a user sits on the chair body 100, the user's own weight will drive the base 200 to move toward the ground, so that the bottom side of the base 200 can move to a height not higher than the height of the roller 400, so that the base 200 can contact the ground. The contact between the base 200 and the ground makes the base 200 and the ground have a large friction, which can make the chair of the present application maintain a relatively stable position and prevent the chair from moving easily.

[0047] During this process, the base 200 will also compress or stretch the elastic member 500, causing the elastic member 500 to deform, and the elastic member 500 is in the first state. When the user stands up from the chair, the restoring deformation force of the elastic member 500 drives the base 200 to move away from the roller 400 along the axial direction of the vertical rod 300, so that the base 200 can move away from the ground, so that the deformation degree of the elastic member 500 is reduced, and the elastic member 500 is in the second state. The base 200 can move away from the roller 400 until the height of the bottom side of the base 200 is higher than the height of the roller 400, so that the bottom side of the base 200 does not contact the ground, so that the roller 400 can be supported on the chair body 100 through the vertical rod 300 and the base 200, and applying external force to the seat can cause the roller 400 to slide along the ground, so that the seat can be easily moved to the target position.

[0048] Specifically, when the user needs to adjust the position of the chair of the present application, he can stand up from the chair body 100, and the restoring deformation force of the elastic member 500 causes the base 200 to move away from the roller 400 along the axial direction of the upright 300 until the height of the bottom side of the base 200 is higher than the roller 400, so that the base 200 is separated from the ground, so that the user can easily push the chair to move to the target position. When the user sits on the chair body 100, the user's own weight can control the base 200 to move toward the roller 400 along the axial direction of the upright 300 until the base 200 moves to a height of the bottom side of the base 200 that is not higher than the roller 400, so that the bottom side of the base 200 contacts the ground.

[0049] In some embodiments, reference Figure 2 , Figure 4 and Figure 5As shown, the base 200 of the present application may specifically include a base 210 and an anti-skid portion 220. The anti-skid portion 220 is connected to the base 210, and a through hole matching the vertical rod 300 may be provided on the base 210. The vertical rod 300 may be movably penetrated through the through hole on the base 210, so that the base 210 can move relative to the vertical rod 300 along the axial direction of the vertical rod 300. Specifically, the aperture of the through hole on the base 210 may be set to be slightly larger than the outer diameter of the vertical rod 300, so that the base 210 can smoothly move along the axial direction of the vertical rod 300. The anti-skid portion 220 may be set to be connected to one side of the bottom of the base 210. When the height of one side of the bottom of the base 200 is not higher than the height of the roller 400, the height of one side of the bottom of the anti-skid portion 220 is not higher than the height of the roller 400, and the anti-skid portion 220 may be sleeved with the roller 400. Specifically, the anti-slip part 220 may be provided with an inner cavity that can accommodate the roller 400, and the anti-slip part 220 also sleeves the vertical rod 300. The end of the anti-slip part 220 close to the roller 400 may have an opening connected to the cavity inside the anti-slip part 220, so that the anti-slip part 220 does not affect the contact between the roller 400 and the ground.

[0050] The anti-slip portion 220 may specifically adopt a truncated cone structure, and the outer diameter of the anti-slip portion 220 gradually increases in the direction away from the roller 400 to the adjacent roller 400, so that the outer diameter of one side of the bottom of the anti-slip portion 220 is relatively the largest. This can increase the contact area of ​​the anti-slip portion 220 when it contacts the ground, thereby making the friction force of the anti-slip portion 220 when it contacts the ground greater, thereby making the relative position relationship of the seat of the present application with the ground more stable when it does not need to be moved.

[0051] In some embodiments, the anti-skid portion 220 in the present application may be made of rubber material, so that the friction between the anti-skid portion 220 and the ground is greater. When the chair of the present application is used in an environment where the floor is tiled, such as a bank hall, or in an environment where the floor is wooden flooring in a home environment, the anti-skid portion 220 made of rubber material can prevent the anti-skid portion 220 from causing damage to the tile or wooden floor. Of course, the anti-skid portion 220 may also be made of a metal material, and a rubber pad is provided on one side of the bottom of the anti-skid portion 220, so that the anti-skid portion 220 has better structural strength, so that the effect of the base 200 supporting the chair body 100 is more reliable, thereby making the seat structure of the present application stable.

[0052] In some embodiments, reference Figure 2 and Figure 4As shown, the elastic member 500 in the present application can be a spring, and the elastic member 500 can be sleeved on the vertical pole 300, and the vertical pole 300 can be provided with a limiting step surface 310. When the elastic member 500 is sleeved on the vertical pole 300, one end of the elastic member 500 can be against the limiting step surface 310 on the vertical pole 300, so that one end of the elastic member 500 can be fixed on the vertical pole 300, and the other end of the elastic member 500 can be against the base 210. In this way, when assembling the elastic member 500, the elastic member 500 can be sleeved on the vertical pole 300, one end of the vertical pole 300 is penetrated through the base 210, and the other end of the elastic member 500 can be against the inner wall of the through hole on the base 210 close to the base 210, so that the elastic member 500 is fixed on the vertical pole 300 and the base 210.

[0053] When the base 200 moves toward the roller 400 along the axial direction of the upright 300, the base 200 can squeeze the elastic member 500, so that the elastic member 500 is compressed, and the elastic member 500 can have a restoring deformation force. When the base 200 is no longer affected by the user's own gravity, the restoring deformation force of the elastic member 500 can drive the height of the base 200 to increase, and reduce the deformation degree of the elastic member 500 or completely restore the deformation.

[0054] In some embodiments, reference Figure 1 and Figure 3 As shown, the number of the vertical poles 300, rollers 400, elastic members 500 and anti-slip parts 220 of the present application can also be set to multiple, multiple vertical poles 300 can be movably connected to the base 200, multiple rollers 400 are respectively connected to the ends of multiple vertical poles 300, multiple elastic members 500 are sleeved on multiple vertical poles 300, and multiple anti-slip parts 220 can be respectively sleeved on multiple rollers 400. In this way, the seat of the present application can be moved by multiple rollers 400, making the seat more stable when moving.

[0055] In some embodiments, reference Figure 2 and Figure 4 As shown, the chair in the present application may also be provided with a fixing portion 320. Among them, after the end of the vertical rod 300 facing away from the roller 400 is penetrated through the through hole on the base 210, one end of the vertical rod 300 can be located outside the base 210. The fixing portion 320 is connected to the end of the vertical rod 300 penetrated through the base 200, and the fixing portion 320 can be limited with the base 200 in the direction of the base 200 toward the chair body 100. In this way, the base 200 can have a maximum movement limited by the fixing portion 320 in the direction facing away from the roller 400, which can prevent the base 200 from being separated from the vertical rod 300.

[0056] Specifically, one end of the vertical pole 300 may be inserted through the base 210, and the area of ​​the end of the fixing portion 320 facing the base 200 may be larger than the area of ​​the opening of the through hole on the base 200, so that the fixing portion 320 can limit the base 200. The end of the vertical pole 300 inserted through the base 200 may be provided with an external thread, and the fixing portion 320 may be provided with an internal thread that matches the external thread of the vertical pole 300, so that the fixing portion 320 can be fixed to one end of the vertical pole 300. In this way, the fixing portion 320 can be easily disassembled and separated from the vertical pole 300, so that the vertical pole 300 can be easily disassembled and separated from the base 200.

[0057] In some embodiments, reference Figure 1 and Figure 3 As shown, the chair of the present application may also include a lifting member 600, which may be disposed between the base 200 and the chair body 100. Specifically, one side of the bottom of the lifting member 600 is connected to the base 200, and the lifting end of the lifting part may be supported on the chair body 100. The lifting member 600 may drive the chair body 100 in a direction toward the base 210 or away from the base 210, so that the height of the chair body 100 may be increased or decreased, so that the height of the chair body 100 may be matched to users of different body shapes, so that users of different body shapes may feel comfortable when using the chair of the present application.

[0058] The lifting member 600 may specifically adopt a hydraulic lifting mechanism, so that the lifting member 600 can drive the height of the chair body 100 to rise by hydraulic pressure. Specifically, an operating rod 610 may also be provided on the lifting member 600, and the user can drive the height of the chair body 100 to rise by toggling the operating rod 610.

[0059] In addition, in other embodiments, the lifting member 600 may also be an electric lifting mechanism or a manually controlled lifting mechanism, so that the height of the chair body 100 can also be controlled by the lifting member 600. The specific structure of the lifting member 600 is not limited in this application.

[0060] In some embodiments, reference Figure 1 and Figure 3As shown, the chair of the present application may also be provided with a lifting rod 110 and a shielding curtain 120. The lifting rod 110 may be provided on the chair body 100, and the lifting rod 110 is configured to be movable relative to the chair body 100 in a direction toward the base 200 or away from the base 200, and the shielding curtain 120 is also provided on the lifting rod 110, so that the shielding curtain 120 can be raised and lowered with the lifting rod 110, so that the shielding curtain 120 can be opened or retracted, and the height of the shielding curtain 120 can be adjusted by the height of the lifting rod 110. When the user sits on the chair body 100, the shielding curtain 120 can shield the user to prevent others from peeping at the user. Specifically, the shielding curtain 120 can be set on the back side of the chair body 100. When the chair of the present application is used in a bank hall environment and the user is handling business, the shielding curtain 120 is opened by the lifting rod 110 by controlling the lifting rod 110 to rise. The shielding curtain 120 can shield the user's back to prevent others from spying on the user's operations such as entering a password.

[0061] In addition, the shielding curtain 120 can also be configured to shield the sides and back of the user, which can further prevent the user from being peeped at by others.

[0062] In some embodiments, reference Figure 1 and Figure 3 As shown, the number of the lifting rods 110 of the present application can be set to two, and the two lifting rods 110 can be set on the back side of the chair body 100 and opposite to each other, and the two ends of the blackout curtain 120 can be connected to the two lifting rods 110 respectively, so that the blackout curtain 120 can be fully opened after the height of the two lifting rods 110 is raised.

[0063] The lifting rod 110 may adopt a telescopic rod structure, and the lifting rod 110 may specifically include a first rod portion and a second rod portion, one end of the first rod portion is connected to the chair body 100, and the first rod portion is sleeved on the second rod portion. When the second rod portion moves relative to the first rod portion, there is a certain damping between the second rod portion and the first rod portion, so that the second rod portion can be positioned at various positions when it moves relative to the first rod portion, so that the second rod portion can be adjusted to different heights. The shielding curtain 120 may adopt a flexible fabric structure, and part of the shielding curtain 120 may be connected to the first rod portion, and specifically can be sleeved on the first rod portion. Another part of the shielding curtain 120 may be connected to the second rod portion, and specifically can be sleeved on the second rod portion. In this way, the second rod portion moves away from the first rod portion to open the shielding curtain 120, and the second rod portion moves toward the first rod portion to shrink the shielding curtain 120, so that the seat structure of the present application is compact and easy to move and carry.

[0064] The first rod portion of the lifting rod 110 can be set as an integral structure with the chair body 100, and the second rod portion is inserted into the first rod portion, so that the first rod portion can also be used to support the user's back to a certain extent, making the user feel more comfortable when sitting on the chair of the present application. The lifting rod 110 can specifically adopt a flexible rod structure.

[0065] In some embodiments, reference Figure 1 and Figure 3 As shown, the chair of the present application may also include an armrest 130, and the number of the armrest 130 may be set to two, and the two armrests 130 may be respectively arranged on both sides of the chair body 100. When a user sits on the chair body 100, the two armrests 130 may provide support for the user's hands.

[0066] In addition, the elastic member 500 in the present application can also be configured such that its elastic restoring force cannot completely lift the base 200 to separate from the ground, so that the user can lift the base 200 through the armrest 130 and push the chair to move to the target position. The elastic member 500 can act as a booster, so that the user can separate the base 200 from the ground by applying a small force to the chair body 100. Accordingly, the elastic member 500 can also adopt a small-sized elastic structural member, so that the structure of the elastic member 500 is relatively more compact, and the structure of the vertical rod 300 can also be set to be relatively more compact. In this way, the preparation cost of the elastic member 500 and the vertical rod 300 can be reduced, so that the preparation cost of the chair of the present application can be reduced.

[0067] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
