Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel chairs, and particularly to a transformable stainless steel chair and its usage method. Background Art

[0002] Traditional stainless steel chairs are seats made mainly of stainless steel, usually used in public places or home environments, with basic seating functions to provide people with rest and support. The structure of a stainless steel chair mainly consists of chair legs, a seat, and a backrest.

[0003] Traditional stainless steel chairs usually only have a single seating function and can only be used for people to sit and rest. They cannot be switched between the forms of a reclining chair and a table and chair combination according to usage needs, and cannot simultaneously meet various needs such as people's rest, work, and dining. When it is necessary to place items, an additional table or other flat surface needs to be found, which brings inconvenience to users.

[0004] Therefore, in view of the problem that traditional stainless steel chairs usually only have a single seating function, can only be used for people to sit and rest, cannot be switched between the forms of a reclining chair and a table and chair combination according to usage needs, and are not convenient for placing items, a transformable stainless steel chair can be designed. Summary of the Invention

[0005] In order to overcome the problem that traditional stainless steel chairs usually only have a single seating function, can only be used for people to sit and rest, and cannot be switched between the forms of a reclining chair and a table and chair combination according to usage needs.

[0006] The technical solution of the present invention is as follows: A transformable stainless steel chair includes arc-shaped stainless steel chair legs. A transformation adjustment component for rotating and adjusting the overall form of the stainless steel chair is provided on the outer side of the arc-shaped stainless steel chair legs. A multifunctional stainless steel plate is installed at the upper end of the transformation adjustment component, which can be leaned on by the user on the front side and can be used as a tabletop on the back side after the form is changed. Both sides of the multifunctional stainless steel plate are rotatably connected with transverse rotating shafts. A variable seat plate component that is snap-connected to the arc-shaped stainless steel chair legs is provided on the outer side of the transverse rotating shafts. A first stainless steel seat plate is fixedly connected to the inner side of the arc-shaped stainless steel chair legs near the top. The variable seat plate component includes a fixed disk connected to the side end of the transverse rotating shaft. A transformable stainless steel armrest frame is fixedly connected to the outer side of the fixed disk. A connecting support rod is fixedly connected to the inner side of the transformable stainless steel armrest frame. A second stainless steel seat plate is fixedly connected to the inner side of the connecting support rod, and the second stainless steel seat plate can be spliced with the first stainless steel seat plate for use.

[0007] Preferably, a support connecting rod is fixedly connected to the inner side of the arc-shaped stainless steel chair legs near the bottom end. The transformation adjustment component includes a fixed sleeve block installed on the outer side of the arc-shaped stainless steel chair legs. An adjustment groove is formed inside the fixed sleeve block, and an adjustment rotating rod is rotatably connected to the inner side of the adjustment groove.

[0008] Preferably, both ends of the outer side of the fixed sleeve block are fixedly connected with limit sleeves, both sides of the adjusting rotating rod are fixedly connected with limit rotating rods, the limit sleeves are internally provided with limit sliding grooves, and fixed abutting blocks are arranged inside the limit sliding grooves.

[0009] Preferably, a limit clamping block that slides inside the limit sliding groove is fixedly connected to the outer side of the limit rotating rod, limit clamping holes adapted to the limit clamping block are formed on both surfaces of the two ends of the fixed abutting block, and an arc-shaped rotating plate is fixedly connected to the outer side of the limit rotating rod.

[0010] Preferably, protective side strips are fixedly connected to both sides of the multi-functional stainless steel plate, and the bottom ends of the protective side strips are fixedly connected to the upper ends of the arc-shaped rotating plates. An angle limiter for cooperating with the fixed disk is installed at the end of the transverse rotating shaft.

[0011] Preferably, one end of the transformable stainless steel handrail frame close to the arc-shaped stainless steel chair leg is fixedly connected with a connecting block, and an arc-shaped support clamping plate is fixedly connected to the inner side of the connecting block.

[0012] Preferably, a clamping block is fixedly connected to one end of the outer side of the arc-shaped support clamping plate close to the arc-shaped stainless steel chair leg, and a clamping position hole for clamping and fixing with the clamping block is formed on the outer surface of the arc-shaped stainless steel chair leg.

[0013] The using method of the transformable stainless steel chair, including the transformable stainless steel chair as described above, the steps are as follows;

[0014] Step 1: When used as a reclining chair, the user can directly sit on the seat surface formed by splicing the first stainless steel seat plate and the second stainless steel seat plate, and lean the back against the front of the multi-functional stainless steel plate;

[0015] Step 2: When used in the form of a table and chair combination, rotate the adjusting rotating rod, the limit rotating rod rotates accordingly, driving the limit clamping block to slide in the limit sliding groove, and the arc-shaped rotating plate can drive the multi-functional stainless steel plate to rotate around the fixed sleeve block accordingly. At the same time, the transverse rotating shaft on the transformable stainless steel handrail frame drives the multi-functional stainless steel plate to rotate, so that the back of the multi-functional stainless steel plate faces upward until the limit clamping block snaps into the limit clamping hole at the other end of the fixed abutting block. At this time, the multi-functional stainless steel plate is used as a tabletop to place items;

[0016] Step 3: At the same time, rotate the transformable stainless steel handrail frame outward, so that the clamping block on the arc-shaped support clamping plate disengages from the clamping position hole of the arc-shaped stainless steel chair leg, continue to pull it outward, rotate the transformable stainless steel handrail frame to a suitable position, separate the second stainless steel seat plate from the first stainless steel seat plate, and use it as a separate seat plate;

[0017] Step 4: When restoring to the reclining chair form, rotate the transformable stainless-steel armrest frame back to its original position, so that the clamping block is reinserted into the clamping hole to fix the variable seat plate assembly. Rotate the adjustment lever in the reverse direction to rotate the multifunctional stainless-steel plate back to the position with the front side facing up for use as the backrest.

[0018] Advantages of the present invention: The transformable adjustment assembly can be used to turn the multifunctional stainless-steel plate into a tabletop, facilitating the user to place items, enabling the rapid switching between the reclining chair and the table and chair, meeting the requirements of various scenarios such as office work, dining, and learning. The second stainless-steel seat plate can be separated from the first stainless-steel seat plate through the variable seat plate assembly to form an independent seat plate, expanding the usage mode. When the stainless-steel chair is in the reclining chair form, it occupies a small space. After switching to the table and chair combination form, the space can be utilized efficiently, making it suitable for small-sized apartments or multifunctional areas. Compared with the stainless-steel chair that usually only has a single seat function and can only be used for people to sit and rest without being able to switch between the reclining chair and the table and chair combination form according to the usage needs, this stainless-steel chair can switch forms, increasing the flexibility of use.
