DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, while sitting on a chair and facing the desk, the front side is the front, the opposite side is the rear, the left side is the left, and the right side is the right.
[0011]
FIG. 1 is a side view showing a desk provided with a flip-up lid unit according to an embodiment of the present invention, and shows a case where it is arranged in parallel as a desk for a lecture room, for example. In FIG. 1, on the top plate 1a of the desk 1, a flip-up type lid unit 2 having an upper top plate 2a arranged with a space from the top plate 1a is disposed at the rear of the top plate 1a of the desk 1. Attached by the left and right support members 2b, 2b, the upper top plate 2a is configured to be rotatable around the hinges 2c, 2c of the support members 2b, 2b. The user who is sitting on the chair 3 can use a notebook computer or the like on the top plate 1a of the desk 1 by flipping up the upper top plate 2a of the lid unit 2 and standing up. . Further, a leg portion 2d is attached to the front portion of the flip-up lid unit 2 so that the upper top plate 2a can be maintained substantially horizontal when the upper lid 2a of the flip-up lid unit 2 is used. The support members 2b and 2b are attached to the top plate 1a from above with a tapping screw or the like.
[0012]
2 and 3 are explanatory diagrams of the opening / closing operation of the flip-up lid unit 2. FIG. An arrow A in FIG. 2 indicates an operation for opening the flip-up lid unit 2, and an arrow B indicates an operation for closing the flip-up lid unit 2. The shape from the rear surface to the upper surface of the left and right support members 2b, 2b is formed in an arc shape (C in the figure), and the center of the radius of curvature of the arc shape (C in the figure) is the rotation of the upper top plate 2a. Is substantially the same as the center (hinge 2c, 2c).
[0013]
Therefore, for example, when closing the flip-up lid unit 2, even if the upper top plate 2a of the flip-up lid unit 2 rotates as shown by the arrow B in FIG. 3, the upper top plate 2a and the support member 2b of the lid unit 2 , 2b is maintained at a substantially constant distance (D in FIG. 3), and even when a finger is on the support members 2b, 2b, the inner surface of the top plate 2a slides the finger on the support member. Therefore, the finger is not sandwiched between the upper top plate 2a and the support members 2b and 2b during the closing operation of the lid unit 2.
[0014]
Further, in a state in which the upper top plate 2a of the lid unit 2 is raised and raised, a fixed interval (for example, a finger of a hand) is provided between the rear end portion of the upper top plate 2a of the flip-up type lid unit 2 and the top plate 1a. (E in FIG. 2), and a space between the rear end of the top lid 2a of the flip-up lid unit 2 and the top plate 1a. Fingers are never pinched.
[0015]
Furthermore, torsion coil springs 2e and 2e are incorporated around the hinges 2c and 2c to compensate for gravity torque when the lid unit 2 is rotated around the hinges 2c and 2c. Since the lid unit 2 does not close suddenly from the state where the upper top plate 2a of 2 is lifted up, a finger or the like is sandwiched between the front portion of the lid unit and the top plate 1a of the desk 1 Can be suppressed. Even if a finger or the like is sandwiched between the front portion of the lid unit and the top plate 1a of the desk 1, the force applied to the sandwiched finger or the like is caused by the gravitational torque compensation effect by the torsion coil springs 2e and 2e. Injuries can be prevented because it is kept small.
[0016]
In the above description, the case where the torsion coil springs 2e and 2e are used as the gravitational torque compensating springs has been described. However, a spiral spring or a torsion bar may be used.
[0017]
4 and 5 are a front view and a plan view showing a state in which the flip-up lid unit 2 is closed. Even when the flip-up lid unit 2 is closed, the left and right sides (F, F in FIG. 5 and F in FIG. 2) and the front side (G in FIGS. 4 and 5) of the lid unit 2 are open. Therefore, it is easy to store a document or document in the lid unit 2 and take out the document from the lid unit 2. In addition, wiring of a notebook computer cable or the like is easy. Not only the left side, right side and front side of the lid unit 2 but also the rear side may be opened.
[0018]
The left and right support members 2b and 2b protrude rearward of the upper top plate 2a, and the inner portions of the support members 2b and 2b are spaces. Therefore, the depth of the space between the top plate 1a of the desk 1 and the flip-up lid unit 2 is widened, and this wide space can be used effectively. For example, in addition to a notebook computer and materials, a rising outlet, extra length wiring, and the like can be stored.
[0019]
Further, as described above, the torsion coil springs 2e and 2e for compensating the gravitational torque disposed around the hinges 2c and 2c are hidden by the support members 2b and 2b (see FIGS. 3 and 4), so that the design surface is provided. Is taken into consideration, and fingers and the like are not caught between the springs 2e and 2e.
[0020]
Furthermore, in the flip-up type lid unit 2 according to the embodiment of the present invention, the hinges 2c and 2c are formed on the left and right support members 2b and 2b of the lid unit 2 as described above, and the hinges 2c and 2c are used to jump. Since the top cover 2a of the liftable lid unit 2 is rotatably supported and the torsion coil springs 2e and 2e for compensating the gravitational torque are incorporated around the hinges 2c and 2c, the above-described effects can be achieved. Cost reduction and reliability improvement can be realized.
[0021]
The “desk” in this specification includes the concept of a so-called table.
[0022]
【The invention's effect】
A flip-up lid unit and a desk equipped with a flip-up lid unit according to the present invention are supported by a support member that can be attached to the rear part of the top plate of the desk, and can be rotated around a hinge of the support member. An upper top plate, and when the upper top plate rotates about the hinge, the shape of the support member from the upper surface to the rear surface is set so that the distance between the rear end of the upper top plate and the support member is substantially constant. Since it is formed in an arc shape, there is an effect that it is possible to prevent finger filling between the upper top plate and the support member during the opening / closing operation of the lid unit.
[0023]
In addition, since the upper top plate is turned up around the hinge and is erected, there is a certain distance between the rear end of the upper top plate and the top plate of the desk to which the support member is attached. In addition to the above-described effects, there is an effect that it is possible to prevent finger filling between the rear end portion of the upper top plate and the top plate of the desk in the standing state of the upper top plate.
[0024]
Furthermore, since the spring for compensating the gravity torque at the time of rotation around the hinge of the upper ceiling plate of the lid unit is provided, the lid unit is not suddenly closed from the standing state of the upper ceiling plate. Therefore, in addition to the above-described effects, it is possible to prevent fingers and the like from being sandwiched between the front portion of the lid unit and the top plate of the desk, and to prevent injuries.
