As one of the types of desks and tables, a structure in which a structure supporting a top board has a frame structure is known. When attaching an optional member to a desk or the like having such a frame structure, conventionally, the lower end portion of the optional member is engaged so as to bite into a part of the frame, and an appropriate position is screwed and fixed to the frame. Thus, the optional member is supported by the frame.
[0003]
[Problems to be solved by the invention]
However, when the optional member includes a counter top plate or the like arranged at a position protruding upward from the top plate, a torsional force exceeding the strength of the member may act on the frame due to the offset load of the counter top plate. For this reason, simply screwing and fixing to the frame may cause damage to the mounting structure of the counter top plate due to deformation of the frame, and thus damage to the function of the desk itself. It is desirable to adopt.

If it is such, the load of an option member will be supported by two places, a flame | frame and a reinforcement beam. For this reason, even if an uneven load is applied, it is possible to avoid the torsional force from being concentrated in one place, and torsional rigidity can be effectively increased.
[0007]
In order to ensure the flexibility of the mounting position of the reinforcing beam and to eliminate the need to perform different processing on the existing frame structure, each frame has a rail groove on the opposing wall that opens continuously. The movable nut is disposed at a position that passes through the rail groove and is movable along the rail groove, and is supported by a backing material so that the inner end side of the movable nut cannot be removed from the rail groove. By screwing the corresponding end of the reinforcing beam to the movable nut, the reinforcing beam can be attached between the frames with the upright wall sandwiched between the end of the reinforcing beam and the backing material. It is preferable.

Yes. For this reason, the function of freely selecting the mounting position of the reinforcing beam 6 along the rail groove 2f can be secured, and at the same time, it is not necessary to perform another processing on the frames 22 and 23, and the existing desk can be used. The application of can also be made extremely easy.
[0037]
Specifically, in the present embodiment, a hook-shaped mounting plate portion 60 is formed on the end portion 6a of the reinforcing beam 6, and two portions of the mounting plate portion 60 are screwed to a movable nut 61 disposed in the rail groove 2f. In this case, a positioning plate 63 having a nut passage hole 63a at a position corresponding to the screwing location of the mounting plate portion 60 is accommodated between the opening edge portions of the rail groove 2f. With the movable nut 61 passed through the passage hole 63a, the reinforcing beam 6 is inserted between the opposing side walls 2c of the frames 22 and 23, and the screw v1 inserted at the screwing location of the mounting plate 60 is positioned at the corresponding position. The movable nut 61 is screwed. For this reason, even if the longitudinal dimension of the reinforcing beam 6 is set relatively tightly to the internal dimension between the opposing side walls 2c of the frames 22 and 23, the movable nut 61 can be accurately positioned and the reinforcing beam 6 can be accurately and accurately processed. It can be attached between the frames 22 and 23.
[0038]
In particular, the backing material 62 is positioned at a position straddling the inner surfaces of the upper and lower side walls 2c located on both sides of the opening of the rail groove 2f by rotating the backing material 62 by a predetermined angle after passing through the opening of the rail groove 2f. Therefore, even if both ends of the rail groove 2f are closed by the side frame 21, the backing member 62 can be easily and reliably positioned in the rail groove 2f.
[0039]
In particular, the other part of the option fixture 52 which is the lower end portion of the option member 5 is screwed and fixed to the reinforcing beam 6, and the pressing force of the screw v2 screwed into the part of the option fixture 52 is used. Therefore, if a screw hole or a screw passage hole is provided even in a newly introduced optional fixture 52 or reinforcing beam 6, the existing frame structure 2 has a screw hole. It is not necessary to perform any other processing such as, and an attachment structure for attaching the optional member can be provided very easily. Even if the optional member is repositioned at various positions, a large number of holes are formed in the rear frame 22. It is possible to effectively avoid the inconvenience that the mounting after the opening causes trouble.
[0040]
That is, basically, the option fixture 52 is screwed to the reinforcing beam 6, so it is not necessary to fix the option fixture 52 to the rear frame 22 so firmly. For this reason, as described above, a part of the optional attachment 52 has a channel portion 52x that holds the rear frame 22, and the screw v2 screwed into the lower piece 52b constituting the channel portion 52x is connected to the channel portion. Even if a simple structure is adopted in which the channel portion 52x is fastened and fixed to the rear frame 2 with the screw v2 and the upper piece 52a, and the screw v2 is tightened with a finger. Even if it only tightens, it becomes possible to arrange | position the option attachment 52 exactly to a predetermined position.

Further, as described above, the lower end portion 52 of the option member 5 is constituted by the option mounting member 52 that can be attached to and detached from the counter top plate 51 that is the option member main body, and therefore the entire option member 5 is made the frame structure 2. The convenience of the attachment work at the time of attaching to can be improved effectively.
[0042]
Further, a gap S is formed between the top plate 3 and the frame structure 2, and the lower end portion 52 of the option member 5 can be inserted through the gap S into a position where the lower frame 52 is supported by the rear frame 22 of the frame structure 2. Therefore, it is not necessary to make the option attachment 52 in a complicated shape, and the option attachment 52 can be accurately set at a predetermined position by a simple operation from the outside.
[0043]
Since it is the above structures, the option attachment structure of this embodiment can become a very useful thing as a structure which supports the option member 5 with the counter top plate 51 in which an offset load may act largely.
[0044]
The specific configuration of each unit is not limited to the above-described embodiment. For example, as shown in FIG. 8, the movable nut 161 has a flat outer shape, while the inlet of the mounting plate portion 160 is fixed to the outer dimension on the short axis side of the movable nut 161. A notch hole 160a whose outer end substantially corresponds to the outer dimension on the long axis side of the movable nut is provided, and the notch hole of each mounting plate 160 is inserted with the reinforcing beam 6 inserted between the opposing side walls 2c of the frames 22 and 23. It is also effective to insert the movable nut 161 from the inlet of 160a and rotate it at the inner end to perform a screwing operation on the movable nut 161. In this way, after inserting the reinforcing beam 6 between the opposing side walls 2c of the frames 22 and 23, the movable nut 161 can be engaged with the notch 160a with the backing material 162 attached thereto. The convenience of attachment work can be improved more effectively, and the positioning plate 63 of the above embodiment is not necessary, so that the number of parts can be reduced.
[0045]
Other configurations can be variously modified without departing from the spirit of the present invention.
[0046]
【The invention's effect】
The present invention is implemented in the form described above, and has the effects described below.
[0047]
That is, according to the option mounting structure of the present invention, when the option member disposed at the position where the option member main body protrudes above the top plate is attached to the frame structure supporting the top plate, the parallel structure forming a pair of frame structures is provided. A part of the lower end of the option member is attached to one of the frames, and the other part of the lower end of the option member is attached to the reinforcing beam laid between the frames.
[0048]
For this reason, the load of the option member can be supported at two locations, the frame and the reinforcing beam, and even if an offset load is applied to the option member body, the torsional force is not concentrated locally at one location of the frame. As a result, it is possible to effectively increase the torsional rigidity and to effectively improve the option mounting strength and ensure the essential function of the frame structure.
[0049]
As a specific structure, each frame has a rail groove continuously opened on the opposing wall, and a movable nut is disposed at a position passing through the rail groove and movable along the rail groove. The inner end side of the nut is supported by a backing material so that it can not be pulled out of the rail groove, and the corresponding end of the reinforcing beam is screwed to the movable nut, so that the end of the reinforcing beam and the backing material When the reinforcement beam can be attached with the upright wall sandwiched between them, the function of freely selecting the attachment position of the reinforcement beam along the rail groove can be secured, and at the same time, it can be attached to the frame etc. Application to existing desks can be made extremely easy by eliminating the need for extra processing.

In particular, when a flange-shaped mounting plate portion is formed at the end of the reinforcing beam and the two portions of the mounting plate portion are screwed to a movable nut disposed in the rail groove, the opening edge of the rail groove In the middle, a positioning plate having a nut passage hole is accommodated at a position corresponding to the screwing position of the mounting plate portion, and a reinforcing beam is inserted between the opposing walls of the frame with the movable nut passing through the nut passage hole. When the screw inserted into the screwing location of the mounting plate is screwed to the movable nut positioned at the corresponding position, the longitudinal dimension of the reinforcing beam is relatively set to the internal dimension between the opposing walls of the frame. Even if it is set tightly, the movable nut can be accurately positioned and the reinforcing beam can be attached between the frames in a proper manner.
[0051]
Alternatively, the movable nut is made to have a flat outer shape, while the inlet of the mounting plate portion corresponds to the outer dimension on the short axis side of the movable nut and the inner end is on the long axis side of the movable nut. With a notch hole that roughly corresponds to the external dimensions, with a reinforcing beam inserted between the opposing walls of the frame, insert a movable nut from the entrance of the notch hole in each mounting plate and rotate it at the inner end to move it. When the screw inserted into the nut is screwed to the movable nut positioned at the corresponding position, the reinforcing beam is inserted between the opposing walls of the frame, and then the movable nut is attached to the backing material. Since it can be engaged with the notch hole in a state where it is in a closed state, it is possible to more effectively improve the convenience of attachment work and to effectively reduce the number of parts.
[0052]
By rotating the backing material by a predetermined angle after passing through the opening of the rail groove, it can be placed in a positioning state at a position straddling the inner surfaces of the upper and lower standing walls located on both sides of the opening of the rail groove. In this case, the backing material can be easily and reliably positioned in the rail groove even if both ends of the rail groove are closed.
[0053]
When the other part of the lower end of the optional member is screwed and fixed to the reinforcing beam, and the part of the lower end is tightened and fixed to the frame using the pressing force of the screw screwed into the part. The existing frame structure does not require any special processing such as screw holes, so it can provide an attachment structure for attaching optional members very easily, and the optional members can be repositioned everywhere. However, it is possible to effectively avoid the trouble such as the trouble of the frame.
[0054]
A part of the lower end portion of the option member has a channel portion that holds the frame, and a screw screwed into one opposing piece constituting the channel portion is pressed against the frame accommodated in the channel portion, and the screw and the other When the channel part is fastened and fixed to the frame with the opposite piece, it is possible to realize an accurate attachment state of the lower end part of the optional member even with a simple structure and simple attachment work. It becomes.
[0055]
When the lower end of the option member is configured with an optional mounting tool that can be attached to and detached from the option member body, the installation work is started and the installation work is performed compared to the case where the entire structure is integrated. It is possible to effectively improve the handling convenience.
[0056]
When a gap is formed between the top plate and the frame structure, and the lower end of the optional member can be inserted into the position where the frame of the frame structure is supported through this gap, work from the outside Thus, the lower end portion of the option member can be easily attached to the frame structure located under the top plate.
[0057]
Alternatively, the top end of the top plate is slightly retracted to expose the upper end of the frame, the top plate of the frame upper end fixing part of the optional member is notched, and further, the lower corner of the top plate mouth of the mounting portion is partially notched and By applying a process such as putting a cap only on the screw fixing portion, it can also be applied to a desk with a very general design.
[0058]
Since the present invention is configured as described above, it is extremely useful when applied to an optional member having a counter top plate as an optional member body, and is also effectively applied to various optional members on which a falling load acts. It becomes possible to do.
