Abstract

The present invention relates to a table for performing tasks such as meetings and, more specifically, to a table comprising: support arms and support legs respectively coupled and fixed to upper and lower ends of vertical supports; a horizontal support connecting the vertical supports; and upper plate supports connecting the support arms. The support arms are formed a single object to be used in common regardless of the application position. According to the application position of the support arms, connection brackets used to be coupled to the ends of the support arms are individually formed, and thus the support arms as the single object can be used for both an end portion and an intermediate portion of the table regardless of a fixed position of a lower portion of the table. By using the support arms, the connection brackets for the end portion and the intermediate portion are simply interconnected and fixed to each other so that the upper plate supports can be strongly coupled and fixed thereto through the connection brackets. Only with minimal components, a normal meeting table can be assembled and manufactured, and an extended table can be efficiently assembled and manufactured. The support arms and the connection brackets can be coupled to each other only in a predetermined direction, and thus the assembly and production of the table are made very quick and easy. The size of the components is also minimized so that the support arms and the connection brackets can be simultaneously molded in a single mold, thereby reducing mold costs and efficiently supplying materials and components.

Description

Table with expandable assembly structure using split bracket}

The present invention relates to a table for performing a task such as a meeting, and more specifically, the support arms and the support angles are assembled inclined to the front and lower ends of the support, respectively, so that the support arms, support and support angles make the top plate. In addition to being stably fixed and coupled, the support arm can be composed of a single entity for each table so that various extended tables can be constructed through the connection of the top plate, and individual connection brackets can be selectively assembled for each support arm. It is for a table that can be assembled in various lengths with minimal components that are simplified as it is configured.

In general, a conference table is used to have a meeting with a large number of people sitting around or having a simple refreshment and having a conversation. Such a table is mainly a circular or elliptical or rectangular plate top plate, and the top plate is supported from the bottom. It consists of a leg member, which is variously classified according to its shape and size, and is appropriately selected and used according to the space of the conference room or the number of people attending the conference.

On the other hand, in the process of preparing for a meeting, if there are many meeting attendees, or if there are many office equipment or documents to be placed on the table, a large table area should be used. It had to be used by arranging three separate tables together or separately using an extended top plate.

However, in the case where a plurality of single tables are used as described above, there is no problem of connection and fixation between the tables, and thus there is a problem in that the tables are opened or moved, and the use thereof is cumbersome. To improve this, registration utility model No. 20-0445448 When a plurality of tables are combined to be used as an expansion table, it is easy to attach and detach the leg member installed at the lower end to a desired position at the same time as being firmly fixed so that the tops of the tables in contact with each other do not deviate, and also extend the leg member When installed at the edge of the table, the angle of the leg member is adjusted to be inclined to the outside, and when installed at the center of the table, the angle of the leg member can be horizontally adjusted to install the leg member. Easy to use due to easy angle adjustment and more top plate Only can be stably supported, but also with a bridge structure of the table that allows economical and may have a neat appearance can install only one middle leg members during use an extension table devised and registration bar.

Subsequently, for the purpose of reinforcing the lower support structure of the conventional table, the first support unit is provided with a first connecting rib to be connected to one side of the connecting beam as shown in Patent No. 10-1379283 and supports the top plate against the floor, As it comprises a second connecting rib to be connected to the other side of the connecting beam and includes a second supporting portion for supporting the top plate against the floor, the bridge is rigid to prevent deformation such as bending, and the top plate is stable with a solid leg It can be supported by, and a table has been devised and registered so as to prevent bending of the top plate by widening the supporting area of the leg with respect to the top plate.

However, in the case of the above-described expandable prefabricated table, the lower support structure is too complicated, requiring a large number of components, and as a result, assembly and productivity are extremely poor.

That is, in the case of a conference table, the length is usually very long compared to an ordinary desk or a regular table, and each component for connecting and fixing the stable support of the top plate and the divided top plate to the long table is the length of the table. Proportionally, it has a very long and large shape.

Therefore, the long and large form of the lower support and each component must be separately manufactured through individual molds, and development and production costs are enormous, as many injection molds or die casting molds for each component must be manufactured. Nevertheless, due to the diverse needs of consumers and the diversification of items, it is inevitable to produce an uneconomical form.

In addition, since each of these components is largely sized for an extended conference table, inventory management of each component is not easy, and there is a considerable burden on the production and storage of components. Of course, it is not suitable for rapid production and supply.
