Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a mounting adjustment fitting for assembled furniture, and more specifically, it is possible to adjust the mounting position of a side plate and a top plate or a bottom plate used for the assembled furniture when they are mounted. And new metal fittings.

<Prior Art> An L-shaped metal fitting generally used in a conventional assembled furniture is a metal fitting having a fixing screw hole for fixing to a plate member, and a side plate of the assembled furniture and a top plate or a bottom plate are butted against each other at a right angle. After the L-shaped metal fitting is brought into contact with the inside or outside of the corner, a screw is fitted into the fixing screw hole and screwed into a screw hole of the plate member to be fixed.

<Problems to be Solved by the Invention> The L-shaped metal fitting in the conventional assembled furniture is fixed to the plate member by screwing a screw into the screw hole and screwing the screw into a corresponding screw stop hole provided in the plate member. However, there is a drawback in that it is inconvenient to make adjustments after fixing the metal fittings. Generally, the size of the plate member in the assembled furniture is predetermined, but it may be necessary to make fine adjustment after the assembly depending on the size and amount of the housed object. In such a case, it would be convenient to have a metal fitting that enables fine adjustment easily, but the conventional L-shaped metal fitting has a fixed mounting position with respect to the plate member and cannot be changed. Can not be achieved.

Also, some mounting adjustment fittings that can change the positional relationship between the plate members have been proposed, but it is difficult to secure a fixed state when using conventional mounting adjustment fittings. On the contrary, there was a problem that the fixing was semi-permanent and the readjustment was impossible.

<Means for Solving Problems> Therefore, the present invention was devised to solve the above problems, and includes a base metal fitting having a screw hole for fixing to an end portion of a plate member of an assembly metal fitting, and a base metal fitting. 2 bent at a right angle
A hollow space L is formed below each of the plate members to accommodate the cross-sectional shape of the base metal fitting slidably.
The shape fitting, the detachable fastening means for fixing the base fitting housed in the hollow space of the L-shape fitting at a predetermined relative position to the L-shape fitting, and the predetermined relative position in the fixed state by the fastening means. An assembled furniture mounting and adjustment metal fitting, comprising: a base metal fitting and a position deviation prevention means provided on a sliding surface of the L-shaped metal fitting for holding the metal fitting.

<Operation> The base metal fitting is inserted into the hollow space provided by each plate member of the L-shaped metal fitting, and is slidable in the hollow space. The base metal fittings that are fixed to the furniture board members in advance are screwed to the L-shaped metal fittings at arbitrary positions in the hollow space, so that the butt corners between the plate members are connected. By loosening the screws that fix the two metal fittings and changing the relative position between the two metal fittings, the positional relationship between the plate members of the furniture can be changed, and the storage space can be adjusted. Moreover, the positional relationship between the plate members is secured in the state where the plate members are fixed by screws.

<Embodiment> A preferred embodiment of the mounting adjustment fitting according to the present invention is shown in FIG. 1 and FIG.

The base metal fitting A is a substantially flat plate-shaped member as shown in the drawing, but the central portion of the upper surface of the base metal fitting A has a recess 10 over its entire length in the longitudinal direction.
Is formed, and the exposed surface is a rough surface 11 such as a knurled surface. Both sides of the recess 10 bulge outward beyond the bottom surface over the required length to form a brim portion 12. Waveform irregularities 13 are formed on the entire lower surface of the brim. Further, the base metal fitting A is provided with a screw hole 14 into which a fixing screw C is screwed. In this embodiment, four screw holes 14 are provided at the four corners of the base metal fitting A. The fixing screw C is a flat screw so that the head does not protrude from the upper surface of the base metal fitting A when it is completely screwed into the screw hole 14 and the base metal fitting A is fixed to the plate material of the assembled furniture. Has been done.

The L-shaped bracket B consists of plates 20, 20 'which are generally folded at right angles, the construction of which is symmetrical about the fold line XX. Therefore, while the following description is for one plate 20, it should be understood that the same applies to the other plate 20 '.

The plate 20 is folded downward at both ends first and then inwardly, that is, these ends 21 and 21 'are formed so as to have a generally U-shaped cross section with the surface of the plate 20. The hollow space formed by the plate 20 and the U-shaped end portions 21, 21 'is large enough to accommodate the cross-sectional shape of the base metal fitting A including the flange portion 12 with a slight margin. Therefore, the base metal fitting A can be freely inserted and slid in the hollow space of the L-shaped metal fitting B. And this U-shaped cross-section end 21,2

Fix each one. This is performed by appropriately screwing a fixing screw C into the fixing screw hole 14 of the base metal fitting A, and screwing it into a screwing hole at a predetermined position provided in the top plate and the side plate in advance. In fixing the base metal fitting A, the four screw holes 14 can be appropriately used, and preferably, the screw C can be screwed and fixed in the two screw holes 14 on the diagonal line.

In this way, the base metal fittings A, which are respectively fixed to the bottom plate and the side plate, are pushed forward so that they can be housed in the hollow spaces provided at both ends of one L-shaped metal fitting B (see arrow in FIG. 1), Fit the flange 12 of the metal fitting A to the L-shaped metal fitting B
Insert it into the U-shaped ends 21, 21 'of the. At the time of this fitting, since the hollow space of the L-shaped metal fitting B is formed to be slightly larger than the cross-sectional shape of the base metal fitting A, the corrugated uneven surface 13 of the brim portion 12 of the base metal fitting A and the L-shaped metal fitting B are joined together. The V-shaped end portions 21, 21 'can be relatively smoothly performed without coming into contact with the corrugated uneven surface 22.

Thus, the base metal fittings A fixed to the bottom plate and the side plate are respectively fitted to both ends of one L-shaped metal fitting B and adjusted to a desired relative positional relationship, and then each of the plates 20, 20 'of the L-shaped metal fitting B is respectively adjusted. The mounting adjustment screws D are respectively screwed into the provided screw holes 23 using a screwdriver or the like. Screw D into the screw hole of plate 20
As the screw D is screwed into the screw 23, the screw D protrudes to the lower side of the L-shaped metal fitting B and finally comes into contact with the rough surface 11 of the recess 10 of the base metal fitting A. By further screwing in from here, the L-shaped metal fitting B is pushed up, and the U-shaped end portions 21, 21 'of the L-shaped metal fitting B are pushed up.
The corrugated uneven surface 22 provided on the base metal fitting A is engaged with the corrugated uneven surface 13 formed on the lower surface of the brim portion 12 of the base metal fitting A. In this state, the L-shaped metal fitting B is completely tightened and fixed to the base metal fitting A without allowing the metal fitting B to slide with the base metal fitting A, and the mounting of these metal fittings is completed. By sequentially connecting the bottom plate / top plate and side plates in this way,
The desired furniture can be assembled.

If it becomes necessary to adjust the positional relationship between these plate members after the furniture has been assembled, the mounting adjustment screw D

When it is desired to increase slightly, loosen the attachment adjusting screw D for the base metal fitting A fixed to the top plate and the bottom plate to the metal fitting connecting the top plate and the side plate and the bottom plate and the side plate, The desired fine adjustment can be easily performed by loosening the screw D again after moving to the desired position.

FIG. 3 shows another embodiment according to the present invention. The base metal fitting A in this embodiment is a plate-shaped body 30 having an inverted trapezoidal cross section.
Screw holes 31 for screwing the fixing screws C, and a plurality of screw holes 32 for screwing the attachment adjusting screws D in the longitudinal direction are formed in series at the four corners. .

The L-shaped bracket B is a pair of plates formed by bending at right angles.
It consists of 40 and 40 '. Of these, only the plate 40 will be described below. The peripheral edge portions 41, 41 ′ of both ends thereof are bent downward inward at an acute angle, and these peripheral edge portions 41, 41 ′ are for receiving the trapezoidal cross section of the base metal fitting A. Giving space. Further, the elongated hole 42 provided in the central portion of the plate 40 is for allowing the attachment adjusting screw D to pass through so as to be screwed into any of the screw holes 32 of the base metal fitting A.

The method of using the mounting adjustment fitting according to the embodiment shown in FIG. 3 will be described. First, the base fitting A is fixed to the vicinity of the end portion of the plate member (for example, the bottom plate and the side plate) of the assembled furniture via the fixing screw C. Then, the L-shaped metal fitting B is positioned at the corner where the bottom plate and the side plate are to be butted, and the base metal fitting A is housed in the hollow spaces in both ends 41, 41 'of the base metal so as to be pushed in the direction of the arrow shown in the drawing. At the position, these metal fittings are fastened and fixed by the attachment adjusting screws D. The pitch of the screw holes 32 of the base metal fitting A is the long holes 42 of the L-shaped metal fitting B.
Since it corresponds to the long diameter of
By appropriately moving it inside and screwing it into one of the screw holes 32, the relative position between the base metal fitting A and the L-shaped metal fitting B can be freely adjusted within a wide range. The relative position of the base metal fitting A and the L-shaped metal fitting B corresponds to the relative position of the plate member (for example, the bottom plate and the side plate) in the assembled furniture,
By appropriately adjusting the positions of the base metal fitting A on both sides of the L-shaped metal fitting B, it is possible to adjust the mounting position between the plate members.

Both the upper surface of the base metal fitting A and the lower surface of the L-shaped metal fitting B in the embodiment shown in FIG. 3 are shown as smooth surfaces, but they may be rough surfaces such as knurls. This allows
The friction between these metal fittings in the state of being fixed by the screw D is increased to prevent slippage, and a more stable fixed state is secured. Further, the base metal fitting A shown in FIG. 3 is symmetrical with respect to the axis line in the sliding direction (arrow), but the plate-shaped body 30 and the screw 30 are provided so as to be symmetrical with respect to the axis line in the direction orthogonal to the sliding direction. If the hole 32 is formed, it can be attached without considering the direction, which is convenient.

The present invention has been described above as a metal fitting used for connecting the bottom plate and the side plate in the assembled furniture, but the same applies to the adjustment of the top plate and the side plate, the side plate and the side plate, or the partition plate and the shelf plate. It goes without saying that metal fittings can be used. Further, in the above description of the illustrated embodiments, it is assumed that the metal fitting according to the present invention is used by being brought into contact with the inside of the corner of the assembled furniture (see FIG. 4). It is also possible to use it for connecting plate members. In this case, it goes without saying that the bending direction of the pair of plates 20, 20 '(Fig. 1) or 40, 40' (Fig. 3) of the L-shaped metal fitting should be reversed.

<Advantages of the Invention> Since the mounting position of the L-shaped metal fitting to the base metal fitting can be freely adjusted by a simple operation, the height and width of the assembled furniture can be finely adjusted, and the amount and size of the stored items can be adjusted. A combined storage space can be secured.
