Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a multiport desk.

[Prior Art] In the following description, a desk used as a dining table will be explained as an example, but the multipurpose desk of the present invention is not limited to this, and also includes an office desk, a work desk, etc.

Traditionally, for example, a desk for eating or having coffee (
Tables with flat tops are used for both home and commercial purposes. At least when having a meal or having a coffee, there are dishes, condiments, paper napkins, toothpicks, flowers, etc. placed on the dining table.

Among the items placed on the dining table, some items, such as tableware, must be put away after use for cleaning, while others, such as flowers, are better left on the table to enhance the beauty of the room. There are preferable items, and items such as seasonings, paper napkins, toothpicks, etc., which spoil the aesthetic appearance if left unattended, so they should be put away as much as possible (hereinafter referred to as seasonings).

Among these, as mentioned above, if left unattended, the seasonings spoil the aesthetic appearance on the dining table as well as the aesthetic appearance in the room.
For example, at home, housewives often store the items in a different place after each use, which increases the housewife's labor, and in stores such as restaurants and coffee shops, they are unavoidably left unattended due to the time-consuming process. There are many accidents,
This results in spoiling the aesthetics of the room.

In addition, for example, during meetings and training sessions, it would be convenient to be able to eat and drink at the same desk in the same room during meals and breaks, but since it takes time to set and serve tableware, it is necessary to set and serve the dishes in advance. They often move to another table or a table in another room to eat or drink coffee.

[Problems to be Solved by the Invention] The present invention has a storage capacity for the above-mentioned seasonings and tableware set in advance, and can be used indoors when one function such as a dining table is mainly required. To provide a multipurpose desk that can quickly respond to changes in cases where other functions such as an ornament or a conference desk are required.

[Means for Solving the Problems] The present invention is a desk having a top plate and legs, in which at least a part of the top plate is provided with an elevating part, and the elevating part moves one part of the top plate when it is raised. The present invention relates to a multi-purpose desk comprising an elevating plate forming a section and an elevating plate elevating mechanism.

The present invention has a top plate and legs, and at least a part of the top plate is provided with an elevating part, and the elevating part includes an upper layer having a flat upper surface and a lower layer having substantially the same shape as the upper layer. , a support that holds the upper layer and the lower layer parallel to each other with an interval between them, a gear with a drive fixed to the lower surface of the lower layer, and a drive fixed at a constant vertical position with respect to the top plate around the lifting part The present invention relates to a multi-purpose desk that is a dining table, and includes a support rod having teeth that mesh with a mechanical gear, and a guide mechanism that guides the upper and lower layers to move up and down along the support rod.

Note that in this specification, the term "lower layer" does not necessarily refer to a layer having a single upper surface, but also includes a layer having a plurality of upper surfaces as long as it is provided below the upper layer.

Furthermore, in this specification, a dining table is a concept that includes not only a table that is used while sitting on a chair, but also a table that is used while sitting around it, such as a tatami table.

[Function] Since the multi-purpose desk of the present invention is provided with an elevating section having an elevating plate that forms a part of the top plate when raised, the elevating plate on which tableware etc. have been set in advance can be lowered. ,
By covering the opening remaining in the top plate with a lid plate made of the same material as the top plate, for example, when having a meal at a meeting or training session, the lid plate can be moved along with documents and the lifting plate can be raised. Just by turning it on, it transforms into a dining table with tableware set. Note that the method of using the elevating plate is not limited to this example.

In addition, in the dining table of the present invention, at least a part of the top plate is provided with an elevating part having an upper layer and a lower layer, so that seasonings can be placed on the lower layer, and when eating, etc., the lower layer is at the height of the top plate. At other times, the upper layer is raised to the same height as the top plate, and lowered until the top layer is at the same height as the top.By simply operating the lifting part, there is no need to store seasonings in a separate location when not in use. It can be stored under the top plate.

This makes it possible to quickly respond to changes in cases where one function, such as a dining table, is primarily required, and cases where another function, such as an interior decoration or a conference table, is primarily required, and the atmosphere can be changed accordingly. It also has the effect of completely changing the

Furthermore, since the lifting part uses a support rod with teeth formed on the surface as described above and a gear with a drive mechanism that meshes with the fallen pile, there is no drive under the lifting plate or the lower layer when descending. All you need is a space to install the machine gear, and since there is only an overhang under the top plate that is about the same size as storage space for tableware, seasonings, etc., you can easily sit on a chair. It is also possible to easily arrange the projecting portion so that it does not hit the knees or feet of the user in a sitting or sitting position. By adopting such a mechanism, it is possible to simultaneously satisfy the requirements of smooth movement, quietness, and economy.
