Description

[Detailed Description of the Invention] The present invention relates to a folding desk in which the desk top can be folded upward by flipping it up.Specifically, the desk top is pivoted between the left and right side panels so that it can freely rotate upward from a horizontal position. The desk top and the drawer frame below are moved backward in response to the upward rotation of the desk top, and advanced in response to the downward rotation in the horizontal direction. As shown in the figure, the link mechanism is interlocked and connected to improve usability as a desk, and a cover is provided to cover the link mechanism from the side to protect the link mechanism and improve its appearance. When providing the cover, the usefulness of the cover is increased and it can be provided at a lower cost by combining the cover with a pocket portion having the function of reinforcing the cover.

Next, the present invention will be explained with reference to the drawings showing an example of applying the present invention to a lighting bureau. The desk top plate 2 is pivotally attached to the front surface of the back side plate 4 inserted and supported between the left and right side plates 3 of the shelf with a hinge 5, and 6 is a magnetic stopper protruding from the inner surface of the side plate 3. Then, rotate the desk top plate 2 upward and hold it so as to cover the front side of the shelf.

A trochanter 7 is installed on each inner surface of the left and right side plates 3, 3 below the back side plate 4.
A plurality of rails 11, 11 having a U-shaped cross section are provided along the outer surfaces of the left and right side frames 10, 10 protruding from the left and right lower surfaces of the upper plate 9 of the drawer frame body 8, and the drawer frame is The body 8 is constructed so as to be able to move back and forth to the front side of the shelf, and a drawer storage box 12 having an open upper surface is inserted and supported in the drawer frame body 8 so as to be movable back and forth.

When the desk top plate 2 is in a horizontal state with respect to the back side plate 4,
When the drawer frame body 8 moves to the forward position by an appropriate distance of 1□ from the shelf surface at the lower surface side position of the desk top plate 2, and conversely rotates the desk top plate 2 upward to cover the shelf surface, the drawer frame body 8
In order to connect the desk top plate 2 and the drawer frame 8 via the two links 13 and 14 of the left and right pots so that the drawer frame 8 moves backward toward the shelf side, there are edges on both left and right ends of the top surface of the desk top plate 2. The guide frame 15 is buried in a long groove hole with an upper surface opening along the first link 1.
The base end of the second link 14 is pivotally attached to the bin 16 in a rotatable manner within the guide frame 15, and the base end of the second link 14 is pivotably attached to the attachment fittings 17 protruding from the top surface of the left and right rear ends of the drawer frame 8. The tip of the second link 14 and the tip of the first link 13, which protrude upward through grooves 19 formed on both left and right ends of the back side plate 4, are connected by an intermediate pin 20.

Furthermore, a cylindrical support 22 is rotatably protruded from the inner surfaces of the left and right side plates 3, 3 of the shelf via a pivot shaft attached to a mounting bracket 21 fixed thereto, and a first link 1 is attached to the cylindrical wall surface of the cylindrical support 22.
A link support 23 is provided in which the link support member 3 is slidably fitted.

24. 24 is an integrated cover that covers from the side the desk top plate link mechanism that moves along the inner surfaces of the left and right side plates 3, 3, each of the integrated covers 24 is made of hard synthetic resin, and the wide side surface 24a of the integrated cover 24 Screws 2 are inserted into each of the side plates 3 through the mounting holes 25 provided through the
6 Stop.

The opening side end of the cover unit 24 is arched so that the entire opening end surface of the cover unit comes into contact with the side plate 3 at this one screwed location.

In the integrated cover 24, 27 is an opening vertically cut out in the front side of the integrated cover 24 in order to insert the first link 13 connected to the desk top plate 2, and 28 is a second opening connected to the drawer frame 8. This is an opening longitudinally cut out in the lower surface of the cover unit 24 for inserting the link 14, and the cover unit 24
The wide side surface 24 has an upwardly opened pocket portion 2 on the outer surface.
There are 9.

This pocket part 29 is used as a letter holder, a brush holder, etc., and also has the function of strengthening and reinforcing the rigidity of the cover unit 24. In the embodiment, the pocket part 29 has a substantially U-shaped shape on the wide side surface 24a corresponding to the outer shape of the pocket part 29. A grooved protrusion 31 is provided to protrude inward, and the two side edges of the front, rear, and bottom of the pocket portion 29 are fitted into the groove and fixed.

Therefore, the protrusion 31 plays the role of a rib, and the protrusion 31
1 and the pocket portion 29 fit together to form a box-like body, the rigidity of the wide side surface 24a of the integrated cover 24 is increased, and openings 27° 2 are formed on the front and lower surfaces of the integrated cover 24.
It is possible to prevent a decrease in strength and flexural deformation caused by notching 8, and by simply fixing the screws 26 at only one place, each end face can be installed in close contact with the inner surface of the side plate 3, and by strengthening the rigidity, the cover can be integrated. Therefore, the entire 24 can be made thin.

Furthermore, 30 is a useful part formed on the upper side of the cover unit 24,
The lower surface of the intermediate shelf board 31 above the inner shelf board 4 enters into the stepped portion 30.

In this configuration, as shown by the solid line in FIG.
When the first link 13 is rotated downward from the position covering the shelf surface, the first link 13 is pulled out from the 23 link supports, and the second link 1 pivotally attached to the tip of the first link 13 is pulled out.
The tip of the second link moves forward in the direction of the sliding pivot member 25 while rotating upward, while the drawer frame 8 is supported by the rail 11, and the base end of the second link is pivoted to the rear of the drawer frame 8. Therefore, when the desk top 2 is rotated until it becomes horizontal as shown by the two-dot chain line in FIG. The two lower surfaces can be brought into contact and supported, eliminating the need for a separate bracket.

A person sitting on a chair on the front end side of the desk top can easily reach the handle of the storage box 12 housed in the drawer frame 8 and pull it out.

As described above, according to the present invention, the rotation and drawer of the top plate 2 and the front and rearward movement of the frame body 8 are linked via the link mechanism, which makes the desk extremely convenient to use. Since we provided a cover 24.24 that covers from the side,
Link 1 even when using the top plate 2 horizontally as a desk
3, 14, the link support 23 and the groove 19 are hidden, so that the appearance is not deteriorated, and the link support 23 and the groove 19 are hidden.
It is possible to prevent dust from accumulating in the inner shelf 9 or pencils or the like from falling into the groove 19 of the inner shelf board 4, thereby making it impossible to move the drawer frame body back and forth and, furthermore, to prevent the desk top plate 2 from rotating.

Moreover, since pockets used for letterheads, brush holders, etc. are attached to the surface of the integrated cover 24, costs can be reduced by sharing parts and the work for attachment can be simplified compared to attaching them separately. At the same time, the design can be kept simple without being bulky.In addition, by attaching the pocket part, the rigidity of the cover is strengthened, so it can be attached tightly to the desk side panel. As soon as possible, cover one 2
4 can be made thinner, which also has the effect of saving material and making it cheaper to manufacture.
