Description

[Detailed description of the invention] [Technical field] The present invention relates to a folding desk, and more specifically to a folding desk that can be stored by raising and swinging the top plate relative to the base. The present invention relates to an operation assisting means such as a gas spring for reducing the operating force when swinging, and a technique for making the lower back surface of an upright top plate invisible from the outside.

[Background technology]

Conventionally, an operation assisting means such as a gas spring is used to reduce the operating force when raising and swinging the tabletop. There was a problem in that the back surface of the lower end of the top plate was also visible from the outside, degrading the appearance.

[Purpose of invention]

The present invention provides a folding desk that uses a rational cover structure to hide operation aids such as a gas cylinder and the back of the bottom of the top when it is stood up and swung, thereby enhancing its appearance. The purpose is to

[Disclosure of invention]

In the present invention, a top plate 3 of a desk 2 that can be swung from a substantially horizontal position to a standing storage position is placed on the side of a stand 1 that is set upright. At both side ends of the plate 3, the upper end of an operation assisting means that applies a biasing force in one direction and expands and contracts, such as a gas spring 5, is connected to the side plate 21 of the base 1, and the lower end of the operation assistance means is connected to the side plate 21 of the base 1. Link 1
The lower end of link 1 is pivotally connected via a piece 9 that is guided by a vertical guide 10 so as to be able to move only vertically.
A flat cover 10 is provided along the side plate 21 of the base 1, and the upper end of the base 1 is pivotally connected to the top plate 3, and covers the operation assisting means and the link 11.
A vertical cover 18 in the form of a curtain plate that covers the back surface of the lower part of the top plate when the top plate 3 is swung to the upright storage position extends between the upper ends, and a rear plate of the base 1 extends from the lower end of this vertical cover 18. The present invention relates to a folding desk that is provided with a top plate lower cover 22 that includes a horizontal cover 19 extending over the entire length of the table, and the above object can be achieved by configuring it in this manner.

Embodiments of the present invention will be described in detail below with reference to the drawings.

There are desks 2 on both the left and right sides of the base 1 configured as a bookshelf.
The top plate 3 is arranged so that it can stand up and swing between an upright storage position (i) shown on the right side of FIG. 1 and a collapsed position (ii) shown on the left side of FIG. The legs 4 are rotatably hinged to the lower surface of the outer end of the top plate 3, and the legs 4 are attached to the first
Storage position where it is folded to the bottom of the top plate 3 shown on the right side of the figure.
It is possible to switch between (iii) and the top support position (iv) shown on the left side of Figure 1. Thus, the desk 2 can be stored in the base 1 serving as a bookshelf, or can be pulled out and used.

A configuration for raising and lowering the top plate 3 with respect to the base 1 will be explained.

In the gas spring 5, a piston (not shown) is slidably provided in a cylinder 6, and high-pressure gas is sealed in one cylinder chamber partitioned by the piston. Connect the cylinder rod 7 connected to the piston to the cylinder 6.
This projecting urging force causes the top plate 3 to
The purpose is to make the robot stand up and swing with a light force.

As shown in FIGS. 2 and 3, the gas spring 5 has a cylinder 6 whose base end is pivotally connected to a side plate 21 of the base 1 by a pin 8. A piece 9 is attached to the tip of the cylinder rod 7 of the gas spring 5, and this piece 9 is housed so as to be slidable only in the vertical direction by a vertical guide 10. A link 11 is rotatably attached to the tip of the cylinder rod 7 via a piece 9 about a shaft 12. The other end of the link 11 is rotatably connected to the base end of the top plate 3 via a connecting pin 13. When the top plate 3 in a horizontal position is lifted by its outer side, the cylinder rod 7, which is urged to expand by the gas pressure of the gas spring 5, descends along the vertical guide 10 and is lifted up with a light force. The plate 3 can be erected and swung.

As shown in FIG. 4, the gas spring 5 and the link 11 are housed within a flat cover 17.
It is hidden from view from the outside. In the figure, reference numeral 22 denotes a cover for covering the lower part of the top plate, and when the top plate 3 is erected, the lower back surface portion 20 of the top plate 3 is not visible from the outside. The configuration will be explained in detail below.

That is, at both side ends of the top plate 3, a gas spring 5 as an operating force assisting means is connected to the side plate 21 of the base 1 by a pin 8, and a link 11 is pivotally connected to the gas spring 5 by a shaft 12. , these gas springs 5 and links 11 are covered with flat covers 17 having elongated holes (not shown) above, and flat covers 17, 17 are arranged along the side plates 21 on both sides of the bag-shaped storage section 14. By doing so, when the opening/closing door 15 attached to the storage section 14 is opened, the gas spring 5 and the link 11 are not visible from the outside. And these flat covers 17,1
As shown in FIG. 1, a curtain plate-shaped vertical cover 18 is provided at the front edge of the storage portion 14 across the upper part of the storage section 7. A horizontal cover 19 is provided over the back panel 16 of the base 1 serving as a bookshelf, and in this way, when the lower back surface portion 20 of the top plate 3 that has been swung upright is opened, the door 15 of the storage section 14 is opened. It is hidden from view. In the figure, 23 is the upper stile of the storage section 14, which corresponds to the lower surface of the top plate 3 in a substantially horizontal position, and the top plate 3 is in a tilted position.
(ii) shall be maintained. 24 is a hit that prevents the top plate 3 from being turned over a certain amount.

[Effect of idea]

In summary, the present invention has a flat cover that covers the operation assisting means such as a gas spring and the link, which is provided along the side plate of the base, so that the top plate can be raised and swung with a light operating force using the operation assistance means. By covering these operation aids with flat covers that run along the side plates of the base, it is possible to prevent the operation aids from being seen from the outside, and to cover the operation aids with flat covers that run along the side plates of the base. A cover for covering the lower part of the top plate is provided, which is composed of a vertical cover in the form of a curtain plate that covers the back surface of the lower part of the top plate when it is swung to an upright storage position, and a horizontal cover extending from the lower end of the vertical cover to the back plate of the base. Therefore, when the top plate is placed in an upright storage position, it is possible to prevent the lower back surface of the top plate from being seen from the outside, which has the advantage of enhancing the appearance of the folding desk.
