When the pulling plate 18 is pulled, the rear end of the pulling plate is fixed and the horizontal bar 46 under the lever hinge 44 of the pulling lever 42 is rotated so that the pulling lever 42 presses the operating rod 24 And a cylinder operating portion 50 which houses the pulling lever pulling means 53 and is attached to the end of the hinge rod cap 40 with a hinge screw 47 and fixed to the bottom surface of the upper plate 3. [

4 to 6, the push bar holder 19-2 attached to the back surface of the blocking wall 13 of the handle plate 11, the pull bar 18, A pulling plate head 19-3 which is fixed to the tip end and is positioned in the pulling plate head hole 15-1 formed at the center of the fixing plate 15 and has a pushing bar groove 19-4 formed on the back face thereof, And a push bar 19-1 for pushing the push bar groove 19-4 and pulling the pull plate head 19-3 when the handle plate 11 is pressed.

The handle plate 11 includes a bending portion 12 for making a space for accommodating a finger and a blocking wall 13 extending from the bending portion 12 to prevent the fingertip from touching the desk frame 1 . The handle plate 11 and the fixing plate 15 are preferably provided with a restoring spring 11-1 as shown in Fig. 5, which is elastically biased to provide a force that the tab 11 is normally opened. The desk frame 11 may be made of various materials such as wood, iron, synthetic resin, and a mixture thereof.

7 to 9, the pulling lever pulling means 53 has a pulling groove 51 formed in the pulling plate bracket 55, which is the rear end side on which the pulling plate 18 moves, A pulling bar 52 coupled to a rear end of the pulling plate 18 to move in the plate groove 54 and a pulling plate 54 having a length longer than the length of the pulling bar 52, A pair of horizontal bars 46 of the pulling levers 42 extending in the lower ends of the pulling bars 52 and interlocked with pulling of the pulling plate 18 are provided at the boundaries between the pulling bars 52, And the pulling lever head 41 pushes the operating rod 24 at right angles to the pulling plate 18. In this case,

As shown in FIGS. 10 to 12, the upper plate 3 is provided with a billet bar 60 which can be separated and combined,

At both ends of the balustrade bar (60), a fixed creep (61) is provided which provides detachment and engaging force with the upper plate (3);

The fixed creep 61 includes a billet bar 61 and a dipper type crepe plate 62 for supporting the side and bottom surfaces of the upper plate 3 and the creep plate 62 at both ends of the billet bar 60, A rotation lever 64 for rotating the push cam 63 so as to push the push cam 63 and a stop cam 62 for moving the push cam 63 to the fixed position, A fixing pipe 68 for receiving the pulling spring 65 and fixing both ends of the padding bar 60 and a stopper 68 for covering the fixing pipe 68 and the diaphragm type crepe plate 62, And a cover plate 66 for guiding the movement of the upper end. (69) integrally protrudes from the center of the upper surface of the fixing pipe (68), rotatably supports the push cam (63), and engages the rotation lever (64).

When the pull tab 11 of the pull tab 10 attached to one end of the upper plate 3 is pulled in the direction of the arrows shown in FIGS. 4 to 6 with the finger, the fixing plate 15 is fixed to the upper plate 3 And is rotated about the handle hinge shaft 17 of the handle plate 11 so that the pulling means 19 acting on the back surface of the handle plate 11 and the blocking wall 13 is operated. The pushing means 19 is rotated together with the push bar 19-1 when the push bar holder 19-2 is rotated on the basis of Fig. 6, for example, 3, the pushing plate head 19-3 is moved in the direction of the arrow in the wire head hole 15-1, and the pushing plate head 19-3 is moved to the leading end The fixed pulling plate 18 is pulled in the direction of the arrow.

The pulling force of the pulling means 19 actuates the cylinder actuating part 50 of Figs. That is, when the pulling bar 52 coupled to the rear end of the pulling plate 18 is pulled in the direction of the arrow in Fig. 9, the pulling pulling bar 52 of the pulling lever pulling means 53 integrally formed vertically with the pulling bar 52 The pulling lever head 41 of the pulling lever 42 is moved in the counterclockwise direction about the lever hinge 44 of the pulling lever 42, And this pushing means that the cylinder rod 23 of the gas spring 20 is changed from the locked state to the free moving state (the operating principle of such a gas spring is a technology known from Korean Public Utility Model Publication No. 1998-063716 Operation explanation is omitted),

The upper plate 3 is held and moved at a desired angle, for example, in a noiseless state as shown in Figs. 13 and 14. When the depression of the handle plate 11 is released, the pushing of the operating rod 24 is released and the gas spring 20 is kept in the locked state.

10 to 13, when the rotary lever 64 is rotated from a horizontal state to a vertical state, the pushing cam 63 shown in FIG. 12 can move the dip- The crease bar 62 is detached from the upper plate 3 because the crease plate 62 of the dipper type is separated from the upper plate so as to be shifted to the dotted line state of FIG. When the rotary lever 64 is rotated in the longitudinal direction after moving to the desired position in this state, the push cam 63 is retracted again and the diaphragm type creep plate 62 is pulled by the pulling force of the pulling spring 65, The upper surface of the upper plate 3 and the lower surface of the upper plate 3 are fixed. Therefore, the booklet is used to support the book when it is used.

As another embodiment of the pulling board pulling means 19 formed on the pulling plate 11 hinged to the fixing plate 15 fixed to the upper plate 3, as shown in Figs. 17 and 18, A push bar holder 19-2 to which the pulling plate 18 can be pulled from the back surface of the blocking wall 13 of the handle plate 11 when the pull plate 11 is pressed around the hinge shaft 17, A push bar 18-1 supported at the push bar holder 19-2 and fitted to the push bar 18-1 so as to support the push bar 18 at the tip end of the push bar 18 -1).

It is possible to exemplify that the handle hole 4 is formed at the edge of the upper plate 3 so as to hold the handle plate 11 by inserting a finger on the upper plate 3 with the handle plate 11. [

As another embodiment of the pulling lever pulling means 53, a fixing screw 18-2 for fixing the rear end side of the pulling plate 18 to the pulling bar extension lever 52-2, as shown in Figs. 15 and 16, A pulling bar hinge 52-1 for engaging the lower end of the pulling bar extension lever 52-2 and a pulling bar hinge 52-1 for pulling the pulling bar extension lever 52-2 horizontally from the lower end of the pulling bar extension lever 52-2, The bar 52 and the operating bar 24 of the gas spring 20 extending from the pulling bar 52 and pulling the horizontal bar 46 of the pulling lever 42 in parallel with the pulling plate 18 And a pulling vertical plate (57) for working.

The operation of another embodiment of the present invention is basically the same as that of the first embodiment. However, in the first embodiment, if the pulling plate and the gas spring are orthogonal to each other, another embodiment is a structure in which the pulling plate 18 and the gas spring 20 are arranged side by side 15 and 16, when the finger plate 110 is pulled toward the fixing plate 15 by inserting the finger into the grip hole 4, the finger bar is rotated around the handle hinge shaft 17 and at the same time, the push bar holder 19 The push bar 19-1 coupled to the push bar 19-1 pulls the pull bar 18 with the push bar 18-1 inserted in the direction of the arrow.

The pulling bar extension lever 52-2 coupled to the rear end of the pulling plate 18 by the fixing screw 18-2 rotates counterclockwise in the state of FIG. 16 around the pulling bar hinge 52-1 The pulling vertical plate 57 formed on the pulling bar 52 rotates the horizontal bar 46 clockwise about the lever hinge 44. [ The pulling lever head 41 integrated with the pulling lever 42 presses the operating rod 24 as shown in FIG. 9 to release the locking of the gas spring 20 so as to form the angle of the upper plate 3, And at the same time, it operates silently, so that it can be used in the reading room or quiet testimony by adjusting the top plate at an angle that does not interfere with other people. These other implementations can be used as reading room desks, and they will be able to function as book reading books separately. In addition, when drawing or drafting, you can use a fixed sketchbook so that additional functions that can not be provided in the reading desk can be provided on the desk top.
