These are basically the same configuration. Therefore, an example of the arrangement on the right side of the top 3 and the moving body 4 will be described below with reference to FIGS.

  The link rod 5 is a plate-shaped metal plate or the like having a substantially square shape. One end of the link rod 5 is attached to a mounting bracket 22 screwed to a portion near the base end of the side surface of the top plate 3, and a pivot shaft 23. On the other hand, the other end of the link rod 5 is pivotally mounted at a portion of the right frame 9b as the movable body 4 that is always forward of the hinge 8. It is pivotally supported with respect to. The support shaft 24 is fixed so as to penetrate in the width direction of the storage case 16 fastened to the side surface of the right frame 9b by a screw 25 (direction parallel to the width direction of the top plate 3) (see FIG. 4 (b)).

  As shown in FIGS. 4, 5, and 7, the storage case 16 is integrally formed in a substantially rectangular shape in a side view. One of the wide surfaces of the storage case 16 (the surface facing the side surface of the side frame 9b) is a horizontally elongated recess for storing the receiving body 20 and a pair of compression springs 21a as the biasing means 21. 26 is formed. In the recess 26, a partition wall 27 is formed with an appropriate length so that the arrangement position of the pair of compression springs 21a is not shifted. In the position adjacent to the recess 26, the other end portion of the link rod 5 and the communication portion 28 capable of facing the cam body 15 fixed to the other end portion with a screw 17 or the like in the recess 26 are provided. Is formed within the width of the storage case 16. Further, a through hole 29 into which the support shaft 24 is fitted is formed in the width direction of the storage case 16 across the communication portion 28. The other of the wide surfaces of the storage case 16 (the surface facing the inner surface of the side plate 3 and the surface on the bottom side of the recess 26) covers the other end of the link rod 5 and the cam body 15. The flat cover plate portion 30 is integrally formed.

  A step portion 31 and a protrusion 32 are formed in a large area on the surface side of the recess 26, and a peripheral edge of the cover plate 33 for closing the recess 26 is fitted into the step portion 31. The fitting hole 33 a of 33 is configured to fit into the protrusion 32. Further, the storage case 16 and the side frame 9b are fixed to the side face 9b with the screws 25 through another mounting hole 33b of the cover plate 33 and an attachment hole 34 formed in the storage case 16. In addition, you may comprise so that the other end of a pair of said compression spring 21a may be supported by the support piece 33c which bent the one side part of the said cover board 33 (refer FIG. 7).

  The receiving body 20 disposed in the recess 26 is provided with a flat plate-like receiving portion 20a facing the peripheral surface (cam surface 15a) of the plate-like cam body 15 and a protruding portion from the receiving portion 20a. And a guide shaft portion 20b that is positioned by being fitted to an inner diameter portion of each compression spring 21a. A contact member 35 made of a material having a small friction coefficient is embedded in one surface of the receiving portion 20a. 35 is configured to abut the circumferential surface of the cam body 15 (cam surface 15a). In this case, when the top plate 3 is in the standing posture and the link rod 5 is standing (see the two-dot chain line in FIG. 5 and FIG. 2), from the rotation center of the cam body 15 (the axis of the support shaft 24). The distance to the contact surface between the cam surface 15a and the contact member 35 is short. Therefore, the receiving body 20 is set so that the pressing force to the cam body 15 by the urging means 21 decreases with the advance in the direction approaching the support shaft 24. On the other hand, when the top plate 3 is in a horizontal position and the link rod 5 is disposed in a substantially horizontally long shape (see the solid line in FIG. 5 and FIG. 3), the cam surface 15 a and the contact surface from the rotation center of the cam body 15. The distance to the contact surface with the contact member 35 is long. Therefore, the receiving body 20 is set so that the pressing force to the cam body 15 by the urging means 21 increases as the receiving body 20 moves backward in the direction away from the support shaft 24.

  The width dimension W1 of the storage case 16 is slightly narrower than the left and right width W2 between the side plate 2 of the desk body 1 and the side frame 9b of the movable body 4, and the storage case 16 is housed in the width W2. And it is arrange | positioned in the clearance gap of the front-back longitudinal direction. Further, the inner surface of the link rod 5 is also disposed so as to be close to the side frames 9b and the side surfaces of the top plate 3 (see FIG. 6). Then, the other end of the link rod 5 and the periphery of the cam body 15 are positioned and covered with the cover plate 30 between the cover plate portion 30 having one wide side surface in the storage case 16 and the side surface of the movable body 4. (See FIGS. 2, 3 and 6).

  Next, the operation of the above configuration will be described. As the handle 40 (see FIG. 1) located on the front side of the standing top 3 is pulled forward and the top 3 is rotated downward, the pair of link rods 5 is rotated downward so that the other end side is close to the horizontal direction, and the moving body 4 is pushed forward through the link rod 5 (see FIG. 3).

  As the link rod 5 rotates in the clockwise direction in FIG. 2 (counterclockwise in FIG. 5), the cam surface 15a of the cam body 15 that rotates integrally with the other end of the link rod 5 is the receiving body. 20 is pressed so as to move backward against the urging force of the urging means 21 (compression spring 21a). The urging force of the urging means 21 increases as the angle at which the other end of the link rod 5 rotates in the substantially horizontal direction (the closer the top 3 approaches the horizontal posture). Therefore, the downward rotation speed of the top plate 3 is suppressed as acceleration near to the horizontal posture is suppressed. As a result, the top plate 3 is slowly placed on the top frame 9a of the moving body 4 (see the two-dot chain line state in FIG. 1 and FIG. 3). The body is not hurt. In addition, the speed at which the moving body 4 is pushed forward is gradually reduced.

  A buffer body 41 made of a soft elastic material such as rubber is fixed to the front portion of the top surface of the top frame 9a with an adhesive or the like. The link rods 5 may be disposed only on either the left or right side of the top plate 3 and the moving body 4, but are preferably disposed on the left and right sides of the top plate 3 and the moving body 4 as described above.

  Contrary to the above, as the top plate 3 in the horizontal posture is rotated upward, the other end side of the pair of link rods 5 is rotated upward so that the movable body 4 is moved backward via the link rod 5. (See FIG. 3).

  As the link rod 5 rotates counterclockwise in FIG. 3 (clockwise in FIG. 5), the cam surface 15a of the cam body 15 that rotates integrally with the other end of the link rod 5 is the receiving body. The distance from the place where the 20 abutting members 35 abut to the axis of the support shaft 24 is shortened. Accordingly, the receiving body 20 pressed by the urging means 21 moves forward so as to press the cam body 15, and the urging means 21 (compression spring 21 a) that presses the receiving body 20 and thus the cam body 15 accordingly. The biasing force gradually decreases.

  Accordingly, the urging force acts on the link rod 5 in the standing direction in the start section in which the top plate 3 in the horizontal posture is turned upward, and the top plate 3 can be lifted with a light force.

  When the top plate 3 is in the standing posture, the entire link rod 5 and the storage case 16 that are substantially upright between the side surface of the top plate 3 and the side surface of the moving body 4 are viewed from the side of the desk body 1. 2 (see FIG. 2), the outer surface of the link cage 5 and the storage case 16 is covered with the side plate 2 and is located at one end (upper part) of the link cage 5. Is in a narrow gap between the inner surface of the side plate 2 and the side surface of the top plate 3, and the storage case 16 is also located between the inner surface of the side plate 2 and the outer surface of the side frame 9 b of the movable body 4. The other end portion of the link rod 5 protruding from the upper side is also in a position very close to the side surface of the top frame body 9a in the moving body 4, and there is almost no gap for a small child's finger to enter, so it is extremely safe.

  Even when the top plate 3 is rotated downward from the standing posture, one end portion (upper portion) of the link rod 5 is in a narrow gap between the inner surface of the side plate 2 and the side surface of the top plate 3, and the storage case 16 is also formed. Positioned between the inner surface of the side plate 2 and the outer surface of the side frame body 9b, the other end of the link rod 5 that moves forward together with the moving body 4 and the cam body 15 are positioned within the width of the storage case 16, Moreover, since the outer surface side of these rotating members (the other end portion of the link rod 5 and the like) is widely covered by the cover plate portion 30, the storage case 16 projects forward from the front edge of the side plate 2 in a side view. Even if it does, there is no possibility that a child's finger will be pinched between a rotation part, such as the other end part of the above-mentioned link rod 5, and a fixed part.

  Such a situation occurs even when the top plate 3 is in a horizontal posture, that is, when the top plate 3 is rotated upward from the state in which the storage case 16 protrudes forward, and the movable body 4 and thus the storage case 16 moves backward. The other end portion of the link rod 5 and the rotating portion such as the cam body 15 are widely covered and protected by the cover plate portion 30.

  The present invention is not limited to the above-described embodiment, and can be embodied in various forms. For example, in the illustrated embodiment, the cover plate portion 30 is formed integrally with the storage case 16, but the separate cover plate portion 30 is fixed to one wide surface of the storage case 16 by screws or the like. Also good. Further, as shown in FIG. 5, a support piece 42 that supports the other end of the compression spring 21 a is disposed on the side away from the position where the receiving body 20 is disposed in the recess 26 of the storage case 16, and the storage case 16. The initial value of the urging force of the compression spring 21a may be adjusted in size by pushing the support piece in the recess 26 with the tip of the adjusting bolt 43 screwed to the side surface of the adjusting bolt 43. As a result, the downward rotation speed or the like of the top 3 can be easily changed.

  Further, in the illustrated embodiment, the support shaft 24 is fixed to the storage case 16, and the other end portion of the link rod 5 and the cam body 15 are pivotally supported so as to be relatively rotatable around the support shaft 24. However, the other end of the link rod 5 and the cam body 15 may be fixed to the support shaft 24 so that the support shaft 24 can rotate with respect to the storage case 16. In this case, as shown in FIG. 9, the other end portion of the link rod 5 and the cam body 15 may be separated from each other in the axial direction of the support shaft 24 and fixed to the support shaft 24 in the storage case 16. good. This is because the support shaft 24 in the present invention only functions as the other end of the link rod 5 and the rotation center of the cam body 15.

  Further, the cam body 15 may be disposed within the width of the storage case 16 and the other end of the link rod 5 may be disposed on one outer surface side of the storage case 16. Even in that case, it is a matter of course that the cover plate portion 30 covers the wide rotation range of the other end of the link rod 5 with the side surface of the movable body 4. If the other end of the link rod 5 and the cam body 15 are arranged within the width of the storage case 16, the apparatus becomes even more compact. Moreover, the other end of the link rod 5 and the rotating portion of the cam body 15 can be protected by the storage case 16.

  If the cam body 15 is arranged within the width of the storage case 16 and the link rod 5 is arranged on one outer surface of the storage case 16, only the link rod 5 can be retrofitted.

  Furthermore, as another modification, it is needless to say that the moving direction of the compression spring 21a and the receiving body 20 in the storage case 16 can be arranged so as not to be parallel to the moving direction of the moving body 4.

  Further, as the second embodiment, as shown in FIG. 10, the other end of the link rod 5 and the cam body 15 arranged in the storage case are mounted on the side surface of the moving body 24 via the support shaft 24. A lever 44 that can rotate around a shaft 45 is configured as a receiving body that contacts the cam surface of the plate-like cam body 15, and the other end of the lever 44 is a tension spring 46, a compression spring, or a twist. The cam body 15 may be configured to be biased by a biasing means such as a spring to apply a pressing force. In this case as well, it is preferable that the lever 44 and the urging means are disposed in the storage case 16 and cover and protect the parts rotating at the cover plate portion. Even when the other end of the link rod 5 and the cam body 15 are mounted on the side surface of the moving body 24 via the support shaft 24 without using a storage case, and the receiving body and the urging means are mounted, the cover plate It is preferable to cover and protect the parts rotating at the part.

  The storage case 16 provided with the cam body 15 and the receiving body 20 and the urging means 21 in each of the above embodiments may be arranged only on either the left or right side of the movable body 4, but each of the above-described embodiments. As described above, it is preferable to dispose the top plate 3 and the movable body 4 on both the left and right sides in order to balance the left and right of the rotation of the top plate 3. Further, in each of the above embodiments, the cam body 15 may be formed integrally with the other end portion of the link rod 5.

  Furthermore, as shown in FIG. 11 as a reference example, a plate cam-like cam body 15 that rotates integrally with the other end of the link rod 5 is provided, and a biasing means is provided on the cam surface 15a of the cam body 15. The spiral spring 47 (or a leaf spring (not shown)) may be arranged so as to always press the free end side. In this case, it is preferable that the other end portion of the link rod 5, the cam body 15, the support shaft 24 that rotatably supports them, and the spiral spring 47 are disposed in the storage case 16. According to this reference example, in addition to the effects of the above embodiments, the receiving body can be omitted, the number of parts can be reduced, and the cost can be reduced.
