Description

  The present invention relates to a desk suitably used in a school or office.

  Currently, office desks used in schools and offices have been proposed that can be stacked when not in use.

  Specifically, the desk includes a top plate and a leg that supports the top plate, and the leg includes a first leg strut that is paired on the left and right sides, and the first leg. A second leg strut that is paired to the left and right with a separation width smaller than the separation width of the strut, and a top plate receiving portion that connects between the upper ends of the first and second leg struts, The first leg struts of other desks having the same configuration are arranged between the two leg struts so that the legs are engaged with each other so that stacking is possible at a predetermined pitch (see, for example, Patent Document 1) ).

  Here, in the desk of the said patent document 1, while adopting the structure which opened all between the lower parts of the said 1st and 2nd leg support | pillar, a metal pipe was used for the leg of such a desk. What was formed using it is used. As a pipe for forming a leg having such a structure, a pipe having a certain thickness, for example, a pipe having a diameter of 19.1 to 25.4 mm, has been used in order to ensure the strength of the leg. Yes.

  Therefore, when storing such desks when not in use, there is a demand for reducing the pitch when stacking a plurality of desks in order to save storage space. As means for reducing the pitch, it is conceivable to make the pipes forming the legs thin. However, in the desk having the above-described configuration, the thickness of the pipe as described above is designed to ensure the strength of the leg body while suppressing the weight of the desk. If the pipes that form the legs are thinned, the strength of the legs may be insufficient.

JP 2002-95531 A

  The present invention pays attention to the above points and aims to solve such problems, that is, to reduce the pitch during stacking while ensuring the strength of the legs.

  That is, the desk according to the present invention comprises a top board and legs that support the top board, and is configured so that the legs can be engaged with each other and stacked at a predetermined pitch. The base is formed by extending an end frame extending in either of the front and rear directions from both ends of the intermediate frame extending in the left and right direction, and the left and right sides of the end frame of the base. A pair of first leg struts, a second leg strut that is erected on the intermediate frame with a separation width smaller than a separation width of the first leg struts, and the second leg struts And a second transverse beam connecting the upper ends of the first and second beams.

  If it is such, since the lower end part of the said 1st and 2nd leg support | pillar is connected with the said base, even if it uses a thin pipe for a leg, the intensity | strength as a leg can be ensured. That is, it is possible to reduce the pitch when stacking the legs using thin pipes while securing the strength of the legs.

  In order to further secure the strength of the leg of such a desk with a simple configuration, it further comprises a first transverse beam connecting between the upper ends of the first leg columns, and the first transverse beam and A configuration in which the second horizontal beam is attached to the lower surface of the top plate is desirable.

  In the desk having the configuration described in the previous stage, in order to facilitate the stacking operation while further increasing the strength of the legs, the desk includes a connecting rod that connects the first horizontal beam and the second horizontal beam, It is desirable that the connecting rod is located inside the side edge of the top plate. In such a case, when the desks are stacked, the connecting rod is positioned between the top plate and the top plate, and the fingers are held in the state where the side edges of the top plate are gripped. Since the fingers are stored in the space formed outside the connecting rod when the desks are stacked, it is easy to release the gripping state and pull the fingers out of this space. is there.

  In addition, in order to allow the counter-use edges of such a desk to be used in contact with each other, the first leg column is arranged on the use edge side of the top plate, and the second leg column is arranged on the counter-use edge side. In this case, it is preferable that the counter-use edge of the top plate is positioned outside the second leg column and the second transverse beam. In such a case, when the counter-use edges of the desk are made to face each other, the counter-use edges of the top plate collide with each other in preference to the second leg column and the second transverse beam. is there.

  As a configuration for forming such a desk with a small number of parts and processing man-hours, there is a configuration in which the base and the first leg column are integrally formed of a common pipe material.

  In addition, as an example of a preferred aspect of such a desk, the first leg column is arranged on the use edge side of the top plate, and the second leg column is arranged on the non-use edge side, and the second leg The thing which provided the curtain between the upper end parts of a support | pillar is mentioned.

  In particular, the curtain plate includes a curtain plate body, an upper bent piece extending from the upper edge of the curtain plate body to the use edge side and attached to the lower surface of the top plate, and a use edge side from the lower edge of the curtain plate body. If the lower folding piece extends to the side, the second leg column is connected by this curtain plate having a U-shape in a side sectional view, so that the strength of the leg body is ensured. However, the legs can be formed using a thinner pipe.

  And, in order to facilitate the convenience of using such desks in the width direction, it is desirable that the base end frame is provided with a connecting tool for connecting to a desk having the same structure. . If it is such, it is because it can suppress that the relative position of the desks which adjoined in the width direction slip | deviates by connecting the desks which have the same structure using a connection tool.

  According to the configuration of the desk according to the present invention, since the lower ends of the first and second leg struts are connected by the base, the strength as a leg is obtained even if a thin pipe is used for the leg. It can be secured. Therefore, in order to reduce the storage space when not in use while ensuring the strength of the leg, it is possible to employ a configuration in which the pitch when the legs are stacked by using a thin pipe is reduced.
