In addition, terms to be described later are terms defined in consideration of functions in an embodiment of the present invention, which may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout this specification.

Disclosed content, as shown in Figure 1, the backrest portion 101, the main leg portion 100, the armrest portion 103, the sub-leg portion 200, in a folding chair consisting of a seat portion 300 About.

The backrest portion 101 is generally formed in a plate shape, but as shown in FIG. 1, the plate shape may be formed in various shapes such as a circle or a rectangle.

In addition, various materials such as plastic, steel, etc. may be used depending on the intended use of the material used for the backrest part 101, but the disclosed invention is intended to be used especially for bathing, which is formed of durable and lightweight plastic. One side (the part where the user's back is supported) has a cushioning function and is preferably made of silicone, which does not absorb water well.

As shown in FIGS. 1 and 5, the main leg part 100 has a generally ∩ shape, and a backrest part 101 is coupled to the upper end and extends downwardly so that the lower end contacts the ground.

The upper end of the main leg portion 100, that is, the portion to which the backrest portion 101 is coupled, is formed by bending a predetermined angle backward so that the back can be supported when the user is seated.

Accordingly, when the user is seated, the user's back is naturally supported.

As shown in FIGS. 1 to 6, an anti-slip cover 140 is formed at the lower end of the main leg part 100 to support a load applied to the chair and prevent slipping in the presence of water.

The non-slip cover 140 may be manufactured in a patch type, a cover type, or in various shapes.

However, considering the fact that it is used in the state of water on the floor and the coupling fixing force with the lower end weakens over time, it is manufactured in a cover type that can be fitted to the end of the main leg part 100, It is preferably formed of a material.

In the conventional case, the shape of the non-slip cover 140 was manufactured differently to enable self-standing when folding the chair.

This resulted in an increase in manufacturing cost and was uneconomical, but the present invention enables self-reliance by the curved portion 110 formed in the main leg portion 100, and is used at the bottom of the main leg portion 100 or the sub-leg portion 200 Since the shape of the non-slip cover 140 can be manufactured and used in the same manner, there is an economic advantage.

In addition, since the main leg portion 100 is integrally produced to form a curved portion 110 to be described later, there is an advantage in that the manufacturing cost is low.

As shown in FIGS. 1 to 6, armrests 103 are formed in pairs on one side of the main leg part 100.

As shown in Figs. 1 and 6, the armrest part 103 is coupled to the main leg part 100 by a hinge so as to be rotatable.

In addition, as shown in FIGS. 1 and 6, an armrest groove 104 into which the main leg 100 is inserted is formed on one side of the armrest 103 in the vertical direction of the armrest 103.

Accordingly, it is possible to minimize the volume when the main leg portion 100 and the sub leg portion 200 are folded, thereby minimizing the space required for storage, thereby providing the user with the advantage of space utilization.

In addition, considering the characteristics of the bath chair, there is an advantage that the user can move the body while seated.

For example, in a state where the user is seated while facing the front of a chair, the arm of the user may be mounted by lowering the armrest part 103.

In addition, in order to wash the user's back in this state, the armrest part 103 in the user's back direction is rotated upward and fixed.

Through this, the user can easily wash their back without raising their body.

The material of the armrest part 103 may be formed in various ways, such as plastic or steel.

However, considering the convenience of use and the selling price, it is made of plastic that is light and inexpensive to manufacture, but one side is a material with cushioning like the backrest part 101 described above to provide comfort to the user as the user's arm is mounted. It is preferably formed of.

As shown in FIGS. 1 to 3, the sub-leg part 200 is formed on the rear side of the main leg part 100 and is coupled to the main leg part 100 through a hinge part 220 so as to be foldable.

The hinge part 220 is positioned to be spaced a certain distance downward from the backrest part 101.

These sub-legs 200 may be formed in various shapes, but when the chair is folded, as shown in Figs. 1 to 3, in order to minimize the volume occupying space and support the load applied to the chair, the armrest unit It is formed on the lower side of the point where (103) is formed, it is preferably formed to have a pipe shape.

This pipe shape (a shape that gets thicker toward the bottom) can effectively support the load applied to the chair.

As shown in FIGS. 1 to 3, a connection part 210 is formed on the outside of the sub-leg part 200 to protrude forward. The connection part 210 may be folded between the sub-leg part 200 and the main leg part 100 by hinge coupling with the hinge part 220 of the main leg part 100.

The method of the hinge coupling is various, but in consideration of the manufacturing cost and ease of assembly, it is preferably formed by bolt and nut coupling.

In addition, as shown in FIGS. 1 to 3, the rear protruding portion 201 is formed to protrude forward on the inner side of the sub leg portion 200.

As shown in FIGS. 1 to 3, the seat part 300 is spaced a predetermined distance downward from the hinge part 220 and is connected to the main leg part 100.

In addition, as shown in FIGS. 3 and 5, the upper surface of the seat 300 is formed to be inclined downward toward the center, and a drain hole 310 is formed through the center.

When the user takes a bath or shower in a seated state by the inclined surface of the seat 300 and the drain hole 310, water accumulated in the seat 300 can be smoothly discharged.

The material of the seat 300 may be formed in various ways, such as plastic, but in consideration of durability, fixing power, weight and manufacturing cost, the lower plate is preferably made of plastic, and the upper plate provides comfort to the user and protects against water. When considering the drainage effect, it is preferable to be made of silicone or rubber.

1 to 3, the curved portion 110 is formed by bending at a predetermined angle at a plurality of points of the main leg portion 100, thereby forming the main leg portion 100 and the sub-leg portion 200 When folded, the lower ends of each of the main leg portion 100 and the sub leg portion 200 are placed on the ground surface at the same level, thereby enabling self-reliance.

To explain this in more detail, as shown in FIGS. 1 to 3, the first curved portion 111 is formed to have a concave upwardly concave arc at the point where the front protruding portion 105 is formed, and the first curved portion 111 is A second curved portion 113 having an arc concave downwards forward is formed at a point spaced a predetermined distance downward from the formed point.

The angle at which the first curved portion 111 and the second curved portion 113 are curved may be formed differently or at various angles.

However, when the chair is folded, the lower ends of the main leg portion 100 and the sub leg portion 200 are placed on the same plane so that the chair must be inverted by itself. As shown in FIG. 6, the first curved portion (111) and the second curved portion 113 are formed to be curved at the same angle, but each arc is preferably formed in the opposite direction.

If it is formed in the same direction, when the chair is folded, the length of the main leg portion 100 is shorter than the length of the sub leg portion 200, and thus there is a problem in that it is impossible to stand alone.

In addition, the curved angle and the number of curved points may be variously formed.

However, since the chair should be self-standing when folded, as shown in FIGS. 3 and 6, when the chair is unfolded, from the hinge portion 220 of the main leg portion 100 to the lower end of the main leg portion 100 The vertical length (L1) of the sub-leg part 200 and the vertical length (L2) from the upper end of the connection part 210 to the lower part of the sub-leg part 200 are the same or have a corresponding value, and the chair is folded. At this time, the vertical length L3 from the hinge part 220 of the main leg part 100 to the lower end of the main leg part 100 and the sub-leg part 200 at the upper end of the connection part 210 of the sub-leg part 200 It is preferable that the vertical length (L4) to the lower end of) is formed to have the same or corresponding value.

When the chair is folded by the shape of the curved portion 110 formed in the main leg portion 100, as shown in FIG. 6, the armrest portion 103 is rotated vertically to be fixed to the armrest groove 104 and the main In a state in which the distance between the lower end of the leg portion 100 and the lower portion of the sub leg portion 200 is minimized, self-standing is possible, and thus the space occupied compared to the conventional folding chair is reduced, thereby providing ease of storage.

As shown in FIGS. 1 and 3, the front protrusion 105 is formed to protrude forward from the main leg portion 100 to which the seat 300 is connected.

In addition, as shown in FIGS. 1 and 3, the end of the front parallel post 107 is coupled to one side of the front protrusion 105.

As shown in Figs. 1 and 6, when the seat 300 is coupled to the front parallel post 107 by a link 400 to unfold the chair, the front hanging groove 301 to be described later is the front parallel post 107 ) Is hung to support the seat 300.

Although the shape of the front parallel post 107 may be formed in various ways, in consideration of the volume that occupies space when the seat 300 is combined with the front hanging groove 301 and the chair is folded, FIGS. 2 and 4 As shown, it is preferably formed in a cylindrical shape.

As shown in FIGS. 1 to 3, the rear protrusion 201 is formed to protrude forward under the connection part 210 of the sub-leg part 200.

In addition, like the front parallel posts 107 described above, the ends of the rear parallel posts 203 are coupled to one side of the rear protrusion 201.

2 and 4, the front hanging groove 301 is formed extending in the horizontal direction on one side of the lower surface of the seat 300.

The length and shape of the front hanging groove 301 may be variously formed, but when the chair is unfolded, the above-described front parallel post 107 is hung to fix the seat part 300 in bar, the front parallel post 107 It is preferable to be formed to have a shape and length corresponding to the shape of ).

For example, when the front parallel post 107 is formed in a cylindrical shape, the front hanging groove 301 must also be recessed inward so that the cylindrical outer surface can be fitted, and has a larger value than the diameter of the front parallel post 107 It is preferably formed.

2 and 4, a rear hanging groove 303 is formed extending in the horizontal direction on the other side of the lower surface of the seat 300.

Although the shape and length of the rear hanging groove 303 can be formed in various ways, as shown in FIG. 2, when the rear hanging groove 303 is coupled to the rear balance post and folded or unfolded the chair, it should be possible to rotate. It is preferable that the rear balance post is formed in a cylindrical shape without jamming on the outer circumferential surface, and correspondingly, the rear mounting groove 303 is also recessed inwardly like the front hanging groove 301 described above, but the rear balance post is fitted and coupled. It is desirable to be formed to have a diameter that can be.

However, when the chair is folded, the rear parallel post 203 and the rear hanging groove 303 must be combined with each other to form a rotating shaft. Therefore, the rear parallel post 203 and the rear hanging groove 303 must be always coupled.

2 and 6, the seat portion 300 is coupled to the front parallel post 107 by a link 400 so that when the chair is folded, the seat portion 300 rotates up and down.

More specifically, as shown in FIGS. 2 and 4, a rotation shaft portion 401 to which a rear parallel post 203 is rotatably coupled is formed on the lower surface of the seat 300.

One or a plurality of rotation shaft portions 401 may be formed on the lower surface of the seat portion 300.

However, when considering the durability according to the lifespan and the support force to support the load of a person due to the characteristics of the chair used by the user sitting, as shown in FIGS. 2 and 4, symmetrically outside the seat part 300 It is preferably formed.

2 and 4, a link fixing part 403 coupled with one end of the link 400 connected to the front parallel post 107 at a point spaced a predetermined distance forward from the rotation shaft part 401 Is formed.

The point where the link fixing part 403 is formed may be formed in various ways, but when the chair is folded, the link fixing part 403 and the link 400 do not contact each other, and when the chair is opened, the link 400 and the link fixing part It is preferable that 403 is formed to be spaced apart from the point where it can be horizontal.

If the position of the link fixing part 403 is formed at a point different from the above-described point, the surface where the link fixing part 403 and the link 400 abuts occurs due to friction during rotation, and the chair When unfolded, a problem of providing inconvenience to the user occurs because the seat portion 300 in a horizontal state cannot be provided.

The link fixing portion 403 and the rotation shaft portion 401 formed on the lower surface of the seat portion 300 are integrally formed with the seat portion 300 by injection or extrusion.

This lowers the manufacturing cost and provides an economical advantage.

Various methods may be used to combine one end of the link fixing unit 403 and one end of the link 400.

However, in consideration of the convenience of assembly and the convenience of use, as shown in FIG. 2, it is preferable to form a hole in each end, make each hole abut, and fix it with a pin 405.

With this combination, when the main leg part 100 is folded into the sub-leg part 200 (when the chair is folded), the seat part 300 rotates upward, and the main leg part 100 is the sub-leg part. When it is opened and unfolded from (200) (when the chair is unfolded), the seat part 300 rotates downward.

In addition, as shown in Figures 2 and 4, the front hanging groove 301 is formed extending in the horizontal direction on the front side of the lower surface of the seat 300.

This front hanging groove 301 is hooked on the front parallel post 107 when the chair is unfolded to stop the rotation of the seat 300 and fix the seat 300 in a horizontal state.

The link 400 and the rotation shaft portion 401 must be coupled to enable rotation to allow the chair to be folded, and the link 400 and the rotation shaft portion 401 are cylindrically formed front parallel posts 107 and rear parallel posts. When considering the shape of the 203, it is formed in a circular shape, but the inside is formed through penetration, and it is preferable to be fitted to the front parallel posts 107 and the rear parallel posts 203 when considering the manufacturing cost and ease of assembly.
