Description

Multifunction table structure}

The present invention relates to a table structure used for various purposes such as learning, office work, or work, and more particularly, improvement of the fastening structure between the four leg supports and the connection support and the support support that are coupled to each other to these leg supports, and It is possible to quickly and powerfully fix the frame body in a simple temporary assembly state to the top plate by fastening them, as well as improving the mutual contact support and increasing the load distribution, and greatly improving the durability of the table as well as the convenience of assembly. Together, the packaging volume can be minimized and the table top can be expanded.

In general, study desks, office desks, and various tables for meeting or working have various shapes, structures, and sizes, and most commonly, a square-shaped table on a plane is mainly used.

The square table as described above is usually installed with vertical support angles in all directions, and a flat top plate is fixed using the support angle, and the support angle is a pair of support angles on one side arranged before and after Are connected to each other with a support at the front end to form a pair of support frames, and then the upper plate is fixed on the support frame of the support frame, or the support angles on all sides are individually configured to separate each of these support angles. It is most common to be made in the form of fixing the top plate on the crossbar after connecting the bar.

In addition, in the square table by the combination of the support angle and the upper plate as described above, a single or a pair of support reinforcements are fixedly formed on the bottom of the table, but the support reinforcement is connected to the support frame of the support frame, or coupled to the support angle. It is made to prevent sagging or bending of the upper plate from the load of the upper plate itself as well as the loads of various sizes and shapes acting on the upper plate as it is connected to the crossbar. A bent body or a square tube body is mainly used.

That is, the first horizontal member and the second horizontal member as in Patent No. 10-2037635; And a vertical member to which ends of the first horizontal member and the second horizontal member are butted and coupled to the outer surface in different directions. A horizontal insertion bracket inserted into the end of at least one of the first and second horizontal members, fixed to prevent separation by a pin member, and having an inclined fastening hole formed inclined toward the vertical member; Including; a vertical insertion bracket inserted into at least one of the first and second horizontal members and having an inclined fastening hole on a straight line coinciding with the inclined fastening hole of the horizontal insertion bracket fixed by being inserted into the end of the vertical member and disposed. It is constructed using a coupling part, and a horizontal insertion bracket is inserted to form a tool through hole in the fixed horizontal member, and a through hole is formed in the vertical member, and the inclination of the horizontal insertion bracket by entering the fastening member into the horizontal member using the tool through hole. A table frame assembly has been devised and registered in which the fastening hole and the inclined fastening hole of the vertical insertion bracket are mutually fastened, and the fastening member is fastened through the through hole to complete the assembly of the coupling part.

However, in the case of the table frame assembly as described above, the vertical member and the first and second horizontal members are each fastened in an end assembly form using a separate bracket, and a load is applied to the assembly portion through the upper plate of the table. In this case, the load of the table is not spread and distributed to the first and second horizontal members, but rather is transmitted to the bracket assembly through the first and second horizontal members, and excessive loads and loads are applied to the assembly. There is.

Therefore, in the case of the end fastening structure as described above, the mutual fastening parts are easily loosened due to excessive load at each fastening part, or deformation or damage of the fastening parts easily occurs, generating unnecessary noise, as well as creating an unstable installation state of the table. Furthermore, it has a closed end that significantly shortens the service life of the table due to the decrease in the durability of the overall fastening part.

Accordingly, the upper plate of the square plate is coupled and fixed on a pair of support frames in which support angles are respectively spaced apart and fixed on both sides of the lower side of the support reinforcement, as in Registered Patent No. 10-2092133 in recent years, and using the support reinforcement The fixed support reinforcement is configured to be in close contact with the bottom surface along the longitudinal direction of the upper plate, but the support reinforcement is divided into two sides, and each divided support reinforcement is configured to be interconnected and fixed through a separate expansion connecting rod. In response to the upper plate with the left and right widths of the standard, the support frame of a single object can be used in common, so the reduction in manufacturing cost and the drastic increase in production efficiency are evident, and the support frame of a single object can be used in common. It is very efficient in terms of transportation, storage, and material supply of components, and since the length of the support reinforcement is significantly shorter than that of the existing one in the delivery and transport process, the support frame can be stored and packaged together with the support frame. It is possible to reduce the delivery cost, and because anyone can easily and quickly assemble and install the entire table, a prefabricated square table with excellent handling and convenience in use has been devised and registered.

However, the support frame applied to the prefabricated square table as described above has a "c"-shaped connection structure in which a pair of support angles arranged before and after are connected by a support reinforcement, which is the manufacturing step of the support frame. In the case of box packaging the "c" shaped support frame in the process of producing the support frame at the factory and then transporting it to the consumer or seller, the corresponding packaging box is very large due to the empty space between the support angle and the support angle. It is very uneconomical because a separate packaging box must be used in the case of an additional pair of brace reinforcements that have a longer length.

In other words, not only the individual unit price of the packaging box has risen significantly, but the number of individuals that can be loaded during individual or mass transportation is significantly reduced, so the excessive expenditure of transportation costs as well as the increase in various logistics costs incurred to store them is excessively excessive. There is.
