We form small desk which we can place mouse. Of course, these various technical configurations are a folding configuration that can be folded and a technical configuration that can be used both in the fixed chair can not be completely fixed. In addition, in the case of a folding chair, the desk can also be folded like a chair. In the case of a non-folding chair, even a desk can form a technical configuration that can be folded on the chair. However, it is also possible to not fold them all. Hereinafter will be described in detail based on the drawings.

1 is a perspective view of a conventional folding chair. It is a folding chair known in general. The invention is not intended to be the only collapsible chair of the illustrated shape. This figure only illustrates the representative folding chair. The present invention includes a technique of forming a desk on a folding chair as shown and a desk on a fixed chair which will be described later.

2 and 3 are diagrams showing the configuration of a chair in which a desk is formed on a folding chair. In the drawings, a detailed description of the desk will be described later. First, in the present invention, it can be seen that the present invention is formed of a body part 1 having a desk formed on a conventional chair 2 and an armrest part 3 supporting the body part. There is. The desk can be formed with a foldable reading table 4, and a cup fixing hole 5 or the like which can fix the cup can be formed.

4 is a configuration diagram of the main body. A desk 6 is formed in the main body, and the desk is rotatably connected to the frame of the chair by the main body supporting member 10. The rotating means 9 is coupled to the main body supporting member, and the main body supporting member and the desk are connected by the rotating means. One end of the support member 11 is rotatably coupled to the main body support member through a slider. The slider moves along the main body support member, and has a structure that can be fixed at a specific position. A detailed description of the slider will be given in FIG. The other end of the brace member is rotatably connected to the pillar of the chair. The rotating means 9 is a means for rotatably connecting the desk with respect to the main body support member. As the rotating means, the rotating means can be made of various other types such as hinges. In the rotating means, the rotation of the desk may be rotated only in a certain angle range, or may be freely rotated without limiting the angle. Since both of them have their own technical features, both of them can be adopted in the present invention. The bottom surface of the desk may be formed with a fastener 8 that securely attaches and detaches the desk to the armrest. In addition, it forms a coupling protrusion 7 protruding from a portion of the lower surface of the desk, it is coupled to the coupling groove 18 of the armrest portion. In the present invention, the technical configuration of the main body covers an important part. The main body is a portion in which the main body of the desk is formed, and provides a function of allowing access to the chair. In order to provide a function of the access, the main body portion is configured to rotate the desk so that the user can enter and exit. In the method of rotating the desk, the desk may be rotated in a plane in which the desk is formed as shown in FIG. 8 to be described later. Alternatively, the desk may be rotated about an axis of the main body support member. If the rotating means is not coupled to the main body, it is not already a function of the main body, but rather a function of the armrest. In the present invention, the main body portion is necessarily defined as combining the main body support member and the desk by the rotation means. Even if the support member has a desk, if it does not have a rotating means, the concept of the present invention does not correspond to the main body, but rather corresponds to the armrest to be described later.

5 is an embodiment of a rotating means. Rotating means means a means for rotating the desk with respect to the main body support member, which can be configured in various forms. As one of the simplest embodiments, there may be exemplified a constitution in which the rotating body 14 having the rotary stopper 15 and the stopper 16 having the rotating range 13 are combined to limit the range of rotation.

The armrest part is responsible for the function of supporting the main body part, and in some cases may also be responsible for the function of the armrest part independently. The armrest part is supported by the armrest support member 19. Armrest 17 is formed in the armrest support member, one end is rotatably connected to the frame pillar of the chair. In addition, the support member 21 is rotatably connected to the intermediate portion of the support member through a slider. The other end of the brace member is rotatably connected to the pillar of the chair. The slider 26 performs a slider movement along an armrest support member, and is comprised so that it may stop at a specific position. The armrest 17 is formed with a coupling groove 18 to which the coupling protrusion of the main body is coupled.

7 is a configuration diagram of the function expansion armrest. This increases the area of the armrest portion and can be conveniently used by adding a variety of functions, such as forming the coupling groove 27 and the cup fixing hole 28. The simplest form as the armrest part is the case consisting of only the armrest support member itself, and the next simple case is to form the armrest support member on the armrest support member to support the desk while supporting the function of the armrest. In addition, if the area of the armrest is increased to add various various simple desk functions to the armrest, this is defined as the function expansion armrest part. The distinction between the main body and the armrest is determined by the presence or absence of the rotating means. In other words, if there is a rotating member that rotatably connects the support member and the desk, it is defined as the main body part, and if there is no rotating member, the armrest part is defined. As described above, the main body and the armrest may be formed by folding the support member, and the supporting members connecting them may be fixedly formed by welding or the like to the frame of the chair. . The description of the fixed type will be described later.

8 is a configuration diagram of the rotating means in the same plane. In order to allow the user to enter and exit the inside of the chair, the desk must be rotated. In this drawing, the desk is an explanatory diagram illustrating a swivel having a structure in which the desk can be rotated within a horizontal plane. The desk is rotated for the user's entrance and exit. At this time, it would be more effective to enter and leave things that were on the desk as it was when rotating. This is possible by rotating the desk in the plane in which it is placed. For this purpose, by forming the rotary table 30 in the main body support member 31, by coupling the desk 29 to the rotary table with a pin, the rotation of the desk is to be made in the plane on which the desk is placed.
