The present invention is composed of a main body portion in which a chair portion and a desk are formed, and an armrest portion for supporting the main body portion and sharing the load of the main body portion. In some cases, however, the configuration of the armrest portion may be omitted, and the main body portion alone may perform the function well, and since the armrest portion alone may fully achieve its own function, such an independent part of the present invention may also be used. Belongs to the realm. In addition, the main body and the armrest portion of the present invention at the same time or each of the configuration to be fixed to the frame of the chair through a single configuration, and also configured to be detachably detached will be within the scope of the present invention. Hereinafter will be described in detail based on the drawings.

1 and 2 are structural diagrams of a chessboard in which the main body and armrests are detachably formed from a chair. The illustrated chess form shows the most representative embodiment that can be detached from the chair and the main body and armrests. Although the present invention is configured in various chairs in the form of the present invention, it can be regarded as a type of the present invention when it corresponds to the present invention in structure or function. Armrest portion 3 and the main body portion 1 constituting the present invention is configured to be detachable to the frame or seat plate of the chair. In the present invention, the main body 1 is formed with a desk, and is detachably coupled to the frame or seat plate of the chair. The armrest part 3 supports the main body and performs a function of sharing the vertical load received by the desk of the main body. However, the armrest can also perform its own function. At this time, it also performs the function of the armrest, and also serves as a simple desk function. The armrest part 3 supporting the main body part is also detachably coupled to the frame or seat plate 5 of the chair. The reading desk 6 which can be folded can be formed in a desk, and the small desk 4 can be detachably attached to a seat board. In addition, the cabinet is formed in the lower portion of the seat plate, so that in the case of a chair having a desk, it is possible to conveniently store the goods. In addition, the cup fixing hole 7 is formed in a part of the desk. The most common method of attaching and detaching in the practice of the present invention is to use bolts and nuts. In the case of using such a method, the main body and the armrest part may be manufactured by distributing and attaching to the chair of various forms that have already been spread so that the chess of the present invention may be manufactured.

Removable structure by bolts and nuts is not shown in this figure, but the application of the present invention will be said to be the easiest embodiment, there is also a removable insert method as shown in FIG. This will be described later.

3 and 4 are structural diagrams of a fully fixed chess where both the main body, armrests and chairs are fixed. The main body 1 and the armrest 3 are configured to be completely fixed to the chair 2 which is fixed. The most common method of fixing in the practice of the present invention is to use bolts and nuts. In the case of using such a method, the main body and the armrest part may be manufactured by distributing and attaching to the chair of various forms that have already been spread so that the chess of the present invention may be manufactured. Fixing structure by bolts and nuts is not shown in the figure, but the application of the present invention will be the easiest embodiment.

5 and 6 are structural diagrams of a fully folded chessboard which can be folded together with the main body, the armrest and the chair. The reason for folding is to make the space small during storage and to facilitate the movement. In addition, logistics costs can be reduced during the production and sales stages. In the folding of the chair, since the folding chair is widely distributed in the related art, description thereof will be omitted. The present invention can be applied to various types of folding chairs even if the chair is not illustrated. The technical description for folding the main body 1 and the armrest 3 will be described. The support member 136 supporting them is rotatably connected to the pillar of the chair.

The support member is formed with a slider 134 which can slide along the support member, and the support member 135 is rotatably connected to the slider. The other end of the brace member is rotatably connected to the pillar of the chair. The slider has a structure in which the position can be fixed at a specific position. Detailed description thereof will be provided with reference to FIG. 16.

7 and 8 are foldable chairs only, and the main body and the armrest are structural diagrams of the chess fixed to the chair. The main body (1) and the armrest (3) to move along the column on the chair, to configure the height adjusting means 11 that can adjust the height. There is a need to adjust the height of the desk to suit the physical condition of the chess user. The height adjusting means 11 may be used by fixing at a desired position. In the chair on which the desk is formed, a small desk 4 may be formed on the side of the seat plate or the storage cabinet 12 may be formed below the seat plate for the purpose of diversification of functions. The height adjusting means and the small desk will be described later in detail.

9 is an explanatory diagram for explaining a technical configuration of a detachable main body portion, a detachable armrest portion, and a detachable booklet. There exist various methods as a technique which enables attachment or detachment. In other words, using screws or detachment by bolts and nuts is the most common method. In the present invention, as an example other than for carrying out the removal of a removable insertion method. These can be applied to both the desk and the detachment of the main body or armrests. The fixing members 130 and 132 are firmly coupled to the seat plate on the bottom surface or the side surface of the seat plate 133. The fixing member has an insertion groove for inserting the support member. That is, the fixing member is formed in a structure capable of inserting the support member (128,131) of the support member of the main body portion or armrest portion or the small desk (126,127). The support member may have various forms, but when the branch support member 129 having two or more branches is used as the fixing member, the support member may be prevented from rotating, thereby ensuring a firm support. . Desorption as described above is preferably made in the lower or side portion of the seat plate. The detachable structure in the present invention will be described at the same time as a structure for attaching or detaching the support member of the main body portion and the armrest portion as well as the desk. When using a notebook, it is preferable that a desk is configured to perform an auxiliary function so that a user can use a desk more efficiently, such as positioning a mouse. In addition, in attaching the support member to the fixing member which is fixed to the seat plate, it is necessary to securely engage with a bolt or the like in order to perform a more firm attachment. To this end, the locking member is configured to the fixing member. When the removable bookshelf is not used, the bookshelf can be stored by inserting the bookshelf upside down into the space below the seat plate.

10 and 11 are structural diagrams of a chess where the main body and the armrest can be folded in a stationary chair. The main body portion 1 and the armrest portion 3 are combined in a form that can be folded to the fixed chair (2).

12 is a configuration diagram of the main body of the chess. The desk 13 is formed in the main body of the chess of the present invention, and the desk is connected by the main body support member 17. The main body support member may be firmly coupled to the frame of the chair by welding or the like, or the main body may be detached from the chair in a detachable configuration by the method described below.

In the case of a folding type, it may be configured to rotate for folding. In the detachable structure, when the support member is detached from the chair, it means that the chess will use only the function of the chair, and when the function of the desk becomes necessary for the chair, the support member is attached to the chair as a necessity. It means to use. The support member in the chess of the present invention can take various shapes. In order not to interfere with the use as a chair, it is preferable to be configured to protrude toward the front of the chair from the frame pillar at the rear of the chair.

However, in a chair having a structure in which it is difficult to form a support member so as to protrude from the frame pillar of the chair to the front part, the support member is formed from the seat plate of the chair, and in this case, the seat plate may not interfere with the function of the chair. It is preferable that the support member is formed upward from the rear plate close to the backrest, so as to protrude toward the front portion so as to form the main body portion and the armrest portion. The child safety chair cited as a prior art in the present invention has the difference that both sides of the chair are covered by the wall for safety. This difference is that the child safety chair is not centered on the functionality of the desk, but safety The purpose of forming a desk is that the chess of the present invention is different from the purpose of forming a desk for the purpose of the desk, and the prior art has a different purpose in forming a desk for safety. . Rotating means 16 formed in the main body portion is a means for rotating the desk so that the user of the desk can enter and exit. Various types of rotating means can be formed. The bottom surface of the desk may be formed with a fastener (15) for firmly attaching the desk to the armrest. It forms a coupling protrusion 14 protruding on a portion of the lower surface of the desk, it is coupled to the coupling groove 22 of the armrest portion. These structures are techniques for ensuring functional robustness in the use of the inventive chess. In the present invention, the main body portion is a very important part in the technical configuration. The main body is the part where the main body of the desk is formed in the chess, and through the technical configuration of the main body, the rotation function of the desk through which the chess user can enter and exit the chair must be provided. In order to provide a function of the access, the main body portion is configured to rotate the simple desk so that the user can enter and exit, the rotation means, the desk is used through the swivel as shown in FIG. The simple desk can also be rotated within a plane, and another method is to rotate the desk up and down. These will be described later. Here, the difference between the body portion and the armrest portion will be described. The armrest part supports the main body part, and may be configured to function as an armrest, or the part of the desk may be divided to be supported by the armrest part in order to enhance various functions. In this case, we define this function as the function expansion armrest part. In this case, both the armrest portion and the main body portion can form a desk. However, the rotation means of the desk for access is to be formed only in the main body. That is, the main body portion is formed by rotating means for rotating the desk for the user's access, and the armrest portion is defined as not forming a rotation means for rotating the desk for the user's access. Therefore, if the rotating means is not coupled to the main body part is not the function of the main body part, but the concept that the concept is moved to the function of the armrest. In the present invention, it is a common method to combine the main body support member and the desk by the rotation means, but when the fixed member desk is formed in the left and right partitioned desk, the main body support member and the desk part are fixedly coupled without the rotation means. Lose. In this case, rotation of the desk for entrance and exit is enabled by the rotation means on the interface between the high policy upper part and the rotary desk part.

13 is an embodiment of a rotating means for rotating a desk. The desk rotating means refers to a means for rotating the desk for the user's entrance and exit, which can be configured in various forms. As one of the simplest embodiments, there is a technique of combining the rotary body 19 having the rotary stopper 20 and the stopper 21 having the rotary range 18 to limit the range of rotation. But it is not necessarily necessary to limit the range of rotation. This is because the rotation of the desk for entry and exit is possible without limiting the range of rotation. As the rotation means, there are extremely various methods such as hinges and pin couplings. There is also a rotating means as shown in FIG. 49.

That is, 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 a swivel in the main body support member, by coupling the desk to the swivel with a pin, the rotation of the desk is to be made in the plane on which the desk is placed.

14 is a block diagram of the armrest of the chess. Armrest part is responsible for the function of supporting the main body portion is formed desk, and in some cases it is also responsible for the function of the armrest independently. The armrest part is supported by the armrest support member 24. This figure shows that the armrest 23 is formed on the armrest support member. The armrest 23 is formed with a coupling recess 22 to which the coupling protrusion of the main body is coupled. When this configuration is used to divide the desk from side to side to provide a standard armrest configuration or more various functions, the desk of the partitioned desk that does not rotate for the user's entrance is fixedly located on the armrest. . This will be referred to as an extension armrest section.

In this case, the area of the armrest is increased, and various functions such as forming the fixing hole of the cup as well as the coupling recess 26 can be conveniently used. Armrest support member may be firmly coupled to the frame or seat plate of the chair, may be formed in a structure that can be attached and detached, and may be configured to rotate for folding have. The simplest form as an armrest part is the case consisting of only the armrest support member itself, the next simple case is to form an armrest in the armrest support member to support the desk while supporting the function of the armrest. Here, the various types of simple fixed desks are also defined as belonging to the armrest part. The armrest support member and the body support member shall be constructed to be symmetrical.

15 is a configuration diagram of the length adjusting means. The main body and the armrest part may need to adjust the length before and after the user's physical condition. As an embodiment of the length adjusting means, the main body support member or the armrest support member 27 is composed of a hollow pipe, the length adjusting member 25 is inserted into the hollow pipe, the support member and the length It is a configuration to adjust the length by sliding the adjustment member. At this time, the long hole 28 is formed in the supporting member in the longitudinal direction, and the length adjusting pin 29 is formed in the length adjusting member, and the length adjusting pin protrudes to the outside of the long hole to move in the long hole. At this time, the spiral is formed on the length adjusting pin, and the length can be adjusted by fixing the position of the length adjusting pin through the nut on the spiral portion. Of course, the length adjusting means may adopt a variety of known techniques.

16 is an explanatory diagram of the operation of the slider. The slider may be used as another embodiment of the height adjusting means or the length adjusting means, and in the configuration of the folding chess, the slider may be used as a means for fixing the desk in a specific position. In FIG. 6 the slider is configured to slide along the support member. A slider stopper 31 is configured on the slider 35. The slider stopper is configured to stop the movement by being caught in the slider stop grooves (30, 32, 33) formed in the support member. The stopper is elastically supported by a spring. To release the slider stopper, pull the slider stopper upwards to separate the slider stopper from the slider stop groove.

17 is a configuration diagram of a divided desk on which a fixed desk portion is formed. In the present invention, the desk is divided for ease of use. Depending on the division method, there are left and right division and front and rear division. It is a concept that the left and right and the front and rear are distinguished by the state seen when the user sits on the chessboard. The main purpose of the left and right partitioning is to rotate the desk for the user's entry and exit, leaving the object placed on the desk as it is not rotating, and rotating the rest of the desk so that the user enters and exits through the rotated part. It is to be configured to do this. The main purpose of the front-rear splitting is to fold the main body and the armrest, and the front-and-rear splitting is necessary for the biggest purpose or other special purpose when the desk is caught by the seat of the chair and the folding is hindered. . In some cases, there is a case of partial division in which the desk is only partially divided.

We will now elaborate on the high-policy supervision. When the user rotates the desk to enter and exit the outside, there is a need for a place where objects left on the desk will be placed. For this purpose, the desk is divided into left and right parts, which are rotated and non-rotated parts. The desk for the part of the desk to be kept flat without being rotated is called a high policy upper part, and the rotating desk part is called a revolving desk part. The high policy upper part 39 is firmly fixed by the main body support member 40. The high policy upper portion and the rotary desk portion are rotatably connected via a rotating means 38 such as a hinge. The rotary desk portion is rotatably coupled to one end of the high policy upper portion, the other end is placed on the armrest support member, wherein the coupling protrusion formed on the rotary desk portion and the coupling recess formed in the armrest portion. The high policy sector is convenient to use if the area is as large as possible. For this purpose, the high policy upper part can be largely formed and a large area toward the body can be formed. In this way, it is desirable to leave a large amount of spare area toward the user's body. In the description of the chess, the concept of the high policy upper part and the revolving desk part among these divisional desk concepts is an important breakthrough. By modifying the concept of the rotary desk, it is possible to derive the concept of the slider desk that is capable of slider in the high policy section. As shown in Fig. 53, that is, the slider may be rotated without rotation, and the same function as that of the rotary desk portion may be achieved. This belongs to the scope of the concept of high policy upper part of the present invention. That is, the desk is composed of a high policy upper part and a slider desk part, the high policy upper part is fixed to the main body support member, and the slider desk part is capable of slider movement along the high policy upper part and is supported by the armrest part. Configuration. This is a technology that allows the user to enter and exit the chair by the slider movement without rotation.

18 is a sectional view of an embodiment of a fixed desk portion. The high policy upper portion 42 described in FIG. 17 is fixed to the main body support member 41, and the rotatable rotary desk portion 43 is connected by the high policy upper portion and the rotating means, and the other of the rotary desk portion One end is placed on the armrest support member 44.

19 is an embodiment in which the main body support member also serves as a rotating means. The main body support member 45 is fixedly coupled to the desk 47 and rotates the main body support member and the desk which are integrally coupled. The rotatable member, such as a pipe, enters inside the main body support member so that it can be rotated even without a separate rotation means. Even in this case, the engaging projection 46 formed on the lower surface of the desk is coupled to the coupling recess 48 formed in the armrest portion.

20 is a block diagram of the large-scale high policy upper part. It is a technology that largely constitutes the area of high policy. As a way to form a high policy upper portion as in this figure, the technical features of the high policy upper portion 49 to the outside of the desk rather than reducing the area of the rotary desk 50 will be.

21 is a configuration diagram of a desk on which slider type left and right wings are formed. There is a method of forming an extension wing to increase the area of the desk. Extended wings mean that the desk is enlarged by folding or slider at the bottom or top of the desk. These expansion wings are in the form of left and right expansion wings and front and rear expansion wings. In order to secure a wider area even after forming the area expansion high policy upper part as in the 20th degree, the extension wing 52 is formed in the high policy upper part 51, and the extension wing moves left and right while sliding in the high policy upper part. It is guided through the support sliding guider member (53). The high policy upper part is fixed to the main body support member 54, and is connected to the rotary desk by the rotating means, and the rotary desk is supported by the armrest support member.

22 is an explanatory diagram of use of FIG. Slider-type left and right extension wings come out of the high policy upper part 55 to form a wider high policy upper part, indicating that the rotary desk part 56 can be rotated through the rotating means.

23 is a configuration diagram of a desk on which folded left and right wings are formed. The extension blade 59 is configured to be folded by the rotation engaging means 58 such as a hinge on the high policy upper part 57 to form the extension blade.

24 is a configuration diagram of the high policy upper part forming the fixture. It is explanatory drawing explaining detachment of the armrest support member 62 through the fixture 61 in which the recessed surface was formed in the lower surface of the desk of the rotary desk part 60. FIG.

25 and 26 and 27 are diagrams of desks in which front and rear wings are formed. A slide guider 65 is formed on the lower surface of the rotary desk 68 and the high policy upper portion 66 in order to increase the use area of the desk, and slider front and rear extension wings 63 and 64 are formed in the slide guider. . Of course, the high policy upper portion and the rotary desk portion is rotatably connected by the rotation means (67).

28 is a cross-sectional configuration diagram of a desk having a high policy upper portion. Since the concept of the high policy upper part has been described with reference to FIG. 17, an embodiment will be described with reference to the rotating means 71 connecting the high policy upper part 70 and the rotary desk part 72. Rotating means is the place where the edges of the high policy top surface and the rotary desk surface meet. As the place where the rotation is made, the end processing is clean, and the frame like the shape of the end is made of male and female on the boundary surface of each desk part to give strength. Explain the insertion.

FIG. 29 is an explanatory view of the configuration of the boundary between the high policy upper portion at the boundary of the main body support member. As the rotation area of the desk for entrance and exit is increased, the entrance and exit is facilitated. Therefore, it is emphasized that this side is configured to have a high policy upper part in which the rotation means 75 is formed at the boundary of the main body support member 74 as shown in this drawing. (73) is the demarcation line. In this case, the area of the rotary desk portion 76 can be increased.

30 is an explanatory diagram of what constitutes a high policy upper part near the middle of the desk. When using a desk, if there are many things placed on the desk, the area of the high policy upper part 77 is required to be large. In this case, however, the area of the rotary desk 79 is reduced, resulting in a reduction in the use area for the user's entrance and exit. Whether the rotary means 79 forming the boundary of these desks will be formed at the boundary of the main body support member 78, or will go to the middle of the desk, or to form in the appropriate part of the desk? You can design according to the environment.

31 is a block diagram of a folding reading stand. The reading stand 80 is supported on the desk by a hinge or the like and can be used only when necessary.

Of course, it is not a city, but since the reading table needs to be fixed at a certain angle, the rotation angle is limited.

32nd and 33rd and 34th are sectional drawing explaining the overlapping desk part, and their function.
