Description

Furniture with a top plate

The present invention relates to furniture with a top board such as a table.
This application claims priority based on Japanese Patent Application No. 2015-103659 filed in Japan on May 21, 2015 and Japanese Patent Application No. 2015-118527 filed in Japan on June 11, 2015. , The contents of which are incorporated herein.

A table for performing various meetings, operations, eating and drinking, and the like includes a top plate and support legs that support the top plate.
In such a table, for example, as disclosed in Patent Document 1, a configuration is disclosed in which a frame member is provided on the lower surface of the top plate, and support legs that are opposed to each other are connected by this frame member. With such a configuration, the upper portions of the support legs are integrally connected, and the bonding strength of the support legs to the top plate is increased.

In addition, furniture with a top board such as a table or desk for performing various meetings, work, eating and drinking, etc. includes a top board and supporting legs for supporting the top board.

In such furniture with a top plate, it is necessary to strengthen the support legs according to the size of the top plate, the size of the load placed on the top plate, and the like.
For example, Patent Document 2 discloses a configuration including a horizontal member that connects left and right legs. By supporting the support leg with such a horizontal member, the support leg is strengthened.
Further, Patent Document 1 discloses a configuration in which a frame member is provided on the lower surface of the top plate and the supporting legs facing each other are connected by this frame member. With such a configuration, the upper portions of the support legs are integrally connected, and the bonding strength of the support legs to the top plate is increased.

In the furniture with a top plate, when power supply, communication, etc. are performed in an electronic device used on the top plate, it is necessary to guide the wiring from the floor surface to the top plate. Therefore, in Patent Documents 1 and 2, in such furniture with a top plate, wiring for power supply, communication, etc. in an electronic device used on the top plate is provided in a wiring insertion space formed inside the support leg. The structure which guides from a floor surface to a top plate by making it penetrate is disclosed. According to such a configuration, it is possible to prevent the wiring from being exposed to the outside, improve the appearance of the appearance, and prevent the wiring from being entangled with the user's foot.

Japanese Unexamined Patent Publication No. 2000-166657 Japan National Fair No.5-222096

However, in the configuration as described above, when the top plate is long in one direction and the distance between the support legs is wide, if the load acting on the top plate is large, the top plate and the frame member are bent downward and supported. The leg may be deformed in the direction in which the distance between the lower ends of the legs increases.
In order to prevent such a phenomenon, it is conceivable to increase the strength of the top plate and the frame material by increasing the thickness in the vertical direction. However, with such a method, the space below the top plate may become narrow and interfere with the user's lower limbs.
The objective of this invention is providing the furniture with a top plate which can suppress interference with a user's leg while raising intensity | strength.

However, in the configuration disclosed in Patent Document 2, since the horizontal member for connecting the legs is provided below the top plate, the user's lower limb interferes with the horizontal member, and the leg storage space is sufficient. May not be secured.
Further, in the configuration disclosed in Patent Document 1, when the top plate is long in one direction and the distance between the support legs is long, the top plate and the frame member are bent downward by a load acting on the top plate, and the support legs May be deformed in a direction in which the interval between the lower end portions of each becomes longer. In order to prevent such a phenomenon, it is conceivable to increase the strength of the top plate and the frame material by increasing the thickness in the vertical direction. However, with such a technique, the space below the top plate is narrowed, and there may be a case where the leg storage space cannot be sufficiently secured.

Further, as disclosed in Patent Documents 1 and 2, in order to insert the wiring into the support leg, the wiring extends along the floor surface from the power supply provided on the floor surface to the lower end of the support leg. Exposed. For this reason, an external appearance may be impaired or a user may step on the wiring along the floor surface under the top plate.
