However, the conventional desk device as described in Patent Documents 1 to 4 described above has the following problems.
That is, in the conventional desk device, an angle adjusting mechanism for adjusting the inclination angle of the top plate is incorporated at a position between the top plate and the support structure. Therefore, when the support structure is a general desk, the angle adjustment mechanism and the inclined top plate are placed on the desk top plate, and the height of the inclined top plate, which is the actual work surface, becomes large. However, there was a problem that the height became difficult for the worker to work.
Moreover, if a backlight is built into the tilted top plate to make it easier to check the negatives and cels of the photograph, the thickness of the tilted top plate will become even larger, so there is room for improvement in that respect. It was.

The present invention has been made in view of the above-mentioned problems, and a desk device provided with a tilting device and a tilting device capable of making the height easy to work by keeping the height of the tilting top plate small. The purpose is to provide.

In order to achieve the above object, the tilting device according to the present invention has a tilting device having a flat upper surface as a working surface and a flat plate-shaped tilting top plate capable of adjusting the tilting angle when the height of the rear side is changed. It is rotatably supported on the rear end side of the inclined top plate around the axis along the extending direction of the rear end, protrudes rearward from the rear end, and a locking portion is provided on the front end side. The support arm is provided, and the support means for supporting the locking portion so as to be repositionable in the front-rear direction, and the support means is arranged behind the inclined top plate. ..

Further, the desk device provided with the tilting device according to the present invention includes a tilting device having the above-described tilting device mounted on a flat plate-shaped desk top plate supported by a support structure, and the supporting means includes the tilting device. It is characterized in that it is arranged behind the inclined top plate on the desk top plate.

In the present invention, the tilted top plate can be tilted at a desired tilt angle by changing the position of the locking portion of the support arm locked to the support means in the front-rear direction. For example, when the locking portion of the support arm is locked at the rearmost position in the front-rear direction of the support means, the inclined top plate is in the horizontal posture, and when it is locked at the frontmost position, the inclined top plate is the most. The posture can be set so that the tilt angle is large.
In this case, since the support arm projects rearward from the inclined top plate and the supporting means is arranged at a position rearward from the inclined top plate, the supporting means is conventionally arranged below the inclined top plate. The height of the work surface of the inclined top plate can be kept lower than in the case of. That is, when the tilting device is placed on a flat desk top plate supported by the support structure, the tilting top plate can be adjusted to the tilt angle desired by the worker as described above, and the work surface. The height of the inclined top plate can be set to a height that makes it easy to work.

Moreover, when the tilting device is placed on the desk top plate supported by the support structure as described above, the support means is provided between the desk top plate and the tilting top plate as in the conventional case. As described above, it is not necessary to make the support structure a dedicated structure, the tilting device can be diverted, and the increase in manufacturing man-hours and manufacturing cost can be suppressed.

Further, in the tilting device according to the present invention, the support means is provided with a guide groove for guiding the locking portion in the front-rear direction, is arranged at intervals in the front-rear direction of the guide groove, and is recessed from the guide groove. A feature is that a plurality of locking recesses are formed, and the locking portion of the support arm is selectively locked to the plurality of locking recesses, whereby the tilted posture of the tilted top plate is changed. May be good.

In this case, the locking portion of the support arm is recessed into a plurality of locking recesses formed at intervals in the front-rear direction of the guide groove to be positioned and selectively locked. The tilted top plate can be changed stepwise to a tilt angle corresponding to a plurality of locking recesses. For example, when the locking portion of the support arm is locked in the locking recess located at the rearmost position in the front-rear direction, the inclined top plate is in a horizontal posture, and when the locking portion is locked in the locking recess located at the frontmost position. The tilted top plate can be in a posture in which the tilt angle is the largest.
By providing the plurality of locking recesses in this way, the inclination angle of the inclined top plate can be adjusted stepwise to a predetermined plurality of angles with a simple structure. Then, since the locking portion of the support arm is firmly supported in the state of being fitted in the locking recess, the tilted posture of the tilted top plate can be maintained in a stable state.

Further, in the tilting device according to the present invention, it is preferable that the guide groove is gradually bent upward gradually or smoothly from the rear to the front.

In this case, since the position of the locking recess on the front side of the guide groove is high, the distance between the locking recess on the front side and the rear end of the tilted top plate at the desired maximum tilt angle can be determined. It can be made smaller. That is, the length of the support arm can be shortened, and the length of the guide groove of the support means in the front-rear direction can be suppressed to be short. Therefore, the length dimension of the support means in the front-rear direction can also be reduced, and the cost can be reduced by reducing the size.

Further, the tilting device according to the present invention may be characterized in that at least a closing plate covering the support arm is provided above the guide groove.

In this case, at least the support arm locked to the support means is hidden under the closing plate and cannot be seen, so that a tilting device having excellent design can be realized.

Further, in the tilting device according to the present invention, it is preferable that the support arm has a shape that does not interfere with the closing plate at a position where the locking portion is locked to the support means.

In this case, the structure is such that the support arm does not interfere with the closing plate when the locking portion is locked to the supporting means or when the locking portion is moved.

Further, in the tilting device according to the present invention, it is preferable that the support arm is bent or curved so as to project downward with the locking portion locked behind the support means.

In this case, when the support arm is supported on the front side of the guide groove, the position of the rear end of the inclined top plate, which is the base end side of the support arm, becomes higher. The distance from the rear end of the tilted top plate when the maximum tilt angle is reached can be reduced. At this time, since the trajectory when the support arm moves is at a position lower than that of the linear support arm, the upper end position of the support means can be kept low, and the equipment can be made compact. it can. Further, in this case as well, since the length of the guide groove of the support means in the front-rear direction can be suppressed to be short, the length dimension of the support means in the front-rear direction can also be reduced, and the cost can be reduced by reducing the size. be able to.

Further, the tilting device according to the present invention may be characterized in that a backlight for irradiating the working surface of the tilted top plate is provided inside the tilted top plate.

In this case, since the supporting means is arranged at a position behind the inclined top plate, the inclined top plate, which is the work surface, is made thin even when the backlight is provided inside the inclined top plate. This makes it possible to bring the height of the inclined top plate closer to the height at which it is easy to work.

According to the tilting device and the desk device provided with the tilting device of the present invention, it is possible to reduce the height of the tilting top plate to a height that makes it easy to work.
