However, in the case of Patent Document 1, since one shelf board is supported on one rail, when a plurality of shelf boards are arranged in multiple stages vertically, a rail or the like is installed for each shelf board. There was a problem that it was necessary and it took a lot of time and effort to change their arrangement.

Further, in the shelf structure shown in Patent Document 2, since the shelf board is supported by the partition plate, not only the rear end portion of the partition plate is supported by the rail on the wall surface, but also the front end portion is supported by the rail at the front end portion of the pillow shelf. In support, the partition plate is supported by the front and rear rails. Therefore, if the partition plate is supported on the rail of the wall surface only at the rear end portion, the load bearing performance of the shelf plate becomes unstable.

The present invention has been made in view of these points, and an object of the present invention is to reduce the number of rails to be attached to the wall surface even in a multi-stage shelf board by modifying the shelf board support structure. Therefore, the arrangement of the shelf boards can be easily changed, and the shelf boards can be stably supported by the rails only on the wall surface.

In order to achieve the above object, in the present invention, a plurality of rails are arranged side by side and fixed to a wall surface, columnar or frame-shaped standing support members are arranged on the rails, and each standing support member is engaged with a bolt. The shape of the fixing screw and the nut member screwed to the screw shaft engage with the rail, and the fixing screw allows the rectangular plate-shaped head to be inserted into the engaging recess on the front of each rail from the front opening. By rotating the head, the state in which the head is engaged with the engaging recess and the state in which the head is detachable from the engaging recess are switched.

Specifically, the first invention relates to a shelf board support structure, and in this shelf board support structure, at least two rails are fixed to the wall surface in a state where they are arranged side by side at intervals, and each rail is fixed at the rear part. Has an engaging recess that opens to the front and is arranged along the rail length direction and the width of the opening is smaller than the width of the back. A plurality of fixing screws are movably and adjustablely engaged with the engaging recesses of each rail in the rail length direction, and the fixing screws allow a plurality of standing support members to be arranged along the vertical direction on the plurality of rails. Are mounted and fixed so that they are lined up in the left-right direction and can be moved and adjusted along the rail. The fixing screw has a pair of lengths that are engaged with a screw shaft portion having a male screw formed on the outer peripheral surface and projecting forward from the engaging recess of each rail and the engaging recess of each rail and facing each other on the outer circumference. It has a rectangular plate-shaped head having a side portion and a pair of short sides, and the length of the short side portion of the head of the fixing screw is smaller than the width of the opening of the engaging recess. The length of the long side is set to be larger than the width of the opening of the engaging recess and smaller than the width of the inner part of the engaging recess. The upright support member includes a screw insertion hole forming portion for forming a screw insertion hole formed of a through hole into which the screw shaft portion of the fixing screw is inserted from the rear side, and the screw insertion hole of the screw insertion hole forming portion. A nut member is screwed into the screw shaft portion of the fixing screw inserted into the screw from the front side of the screw insertion hole forming portion, and the screw insertion hole forming portion is sandwiched and fixed between the nut member and the rail. It is characterized in that a shelf board arranged along the left-right direction is supported between the plurality of upright support members.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiments are merely exemplary and are not intended to limit the present invention, its applications or its uses.

1 and 2 show a shelf structure according to an embodiment of the present invention, in which 1 is a wall surface such as an interior of a building, and the wall surface 1 is joined to the wall surface 1 in a vertically arranged state, for example. The three mounting panels 2, 2, ... Are fixed. The height position of the joint between the two mounting panels 2 and 2 adjacent to each other on the top and bottom is the rail mounting position, and the rail mounting positions are, for example, two places on the top and bottom. At the upper end of the lower mounting panel 2, a female recess 5 (female recess) in which the middle portion in the thickness direction (front-back direction) is cut off from the upper end surface is formed, and the lower end of the upper mounting panel 2 is provided. The male fruit ridges 6 (male convex parts) are formed by excising the front and back portions excluding the middle part in the thickness direction from the lower end surface, and the male fruit ridges 6 are formed on the female fruit ridges 5. To form a joint portion of the actual structure, and both mounting panels 2 and 2 are joined to each other at this joint portion. The male ridge 6 at the lower end of the upper mounting panel 2 is fitted halfway to the female ridge 5 at the upper end of the lower mounting panel 2 instead of at the back, and both mounting panels 2 and 2 are up and down. They are joined with a predetermined interval in the direction. Further, the front corner portion of the lower end portion of the upper mounting panel 2 is directed toward the rear side toward the lower side, and the front corner portion of the upper end portion of the lower mounting panel 2 is directed toward the rear side toward the upper side. Each is cut out, and the notched portion and the front side surface of the male ridge 6 form a concave groove portion 8 having a substantially V-shaped cross section with the front side surface of the male ridge 6 as the bottom surface. Further, the concave groove portion 8 communicates with the inner portion of the female actual concave groove 5 through a gap on the lower side of the front surface of the male actual convex article 6.

Two upper and lower rails 11 and 11 extending in the left-right direction are attached and fixed to the two upper and lower concave groove portions 8 and 8 formed between the mounting panels 2, 2 and ... Each of the rails 11 is made of an extruded material such as metal, and is arranged in the front portion thereof along the left-right direction (rail length direction) so as to open to the front side, as shown in an enlarged manner in FIG. The substantially V-groove-shaped engaging recesses 12 (engagement recesses) are formed so as to be continuous over the entire length direction of the rail 11. The rails 11 corresponding to the upper and lower edges of the opening of the engaging concave groove 12 are formed with ridges 14, 14 protruding in the vertical direction toward the mating side, and the ridges 14, 14 are formed. The vertical width d1 of the opening of the engaging concave groove 12, which is the interval between them, is smaller than the vertical width d2 of the inner portion (d1 <d2), and the engaging concave groove 12 has a medium-expanded cross-sectional structure. ing.

Further, at the bottom of the engaging concave groove 12, a bottom groove portion 12a having a substantially V-shaped cross section is formed by digging deeper into the bottom portion, and a screw insertion hole 16 is formed through the bottom portion. As shown in FIG. 3, mounting screws V, V, ... (Mounting screws) are inserted into the screw insertion holes 16 at the bottom of the engaging groove 12, and the male and female ridges 6 and female dents of the mounting panels 2 and 2 are inserted. The rail 11 is attached and fixed to the wall surface 1 by screwing it into the wall surface 1 via the portion on the rear side of the strip 5, and the head V1 of each screw V is accommodated in the bottom groove portion 12a.

A fitting ridge 15 having a rectangular cross section, which is arranged along the rail length direction, is integrally projected from the lower portion of the rear surface of the rail 11. Then, with respect to the upper and lower mounting panels 2 and 2, the rear portion of the rail 11 is housed in the concave groove portion 8 on the front surface of the joint portion of both mounting panels 2 and 2, and the fitting ridge 15 is both on the bottom portion of the concave groove portion 8. It is fixed in a state of being fitted to the inner portion of the fitting ridge 15 through a gap between the mounting panels 2 and 2. As described above, the two rails 11 and 11 are fixed to the wall surface in a state where they are arranged side by side at intervals in the vertical direction, and the lower rail 11 is located at a height of, for example, 120 mm from the floor surface 9, and the upper rail 11 is located. Are similarly located, for example, at a height of 1680 mm.

For example, two fixing screws 18 and 18 are mounted and fixed in the engaging concave groove 12 of each of the rails 11 so as to be movable and adjustable in the left-right direction along the rail 11, and the position and the lower side of the fixing screws 18 on the upper rail 11. The position of the fixing screw 18 on the rail 11 corresponds to the upper and lower sides. As shown in an enlarged manner in FIG. 8, each of the fixing screws 18 has a screw shaft portion 19 (shaft portion) having a male screw formed on the outer peripheral surface thereof and a base of the screw shaft portion 19 thereof, similarly to a normal bolt. The structure has a head 20 integrally formed at the end, but the head 20 is different from a normal bolt. That is, the head portion 20 has a rectangular plate shape having a pair of short side portions 20a, 20a and a pair of long side portions 20b, 20b facing each other on the outer circumference, and the length Lx of the short side portions 20b is The vertical width d1 of the opening of the engaging concave groove 12 in the rail 11 is smaller (Lx <d1), and the length Ly of the long side portion 20b is larger than the vertical width d1 of the opening of the engaging concave groove 12. (D1 <Ly) and slightly smaller (Ly <d2) than the vertical width d2 at the inner part of the engaging concave groove 12.

Further, when a pair of diagonally opposed corner portions of the head 20, for example, long side portions 20b and 20b of the head 20 are in a state along the left-right direction (fixed) as shown in FIG. 11A. Chamfered portions 20c and 20c are formed at the upper left and lower right corners (when the screw 18 is in the disengagement posture described later). The reason for forming the chamfered portions 20c and 20c is that if these chamfered portions 20c and 20c are not formed, the length between the two corner portions becomes larger than the vertical width d2 at the inner portion of the engaging recessed groove 12. When the head portion 20 is rotated around the screw shaft portion 19 in a predetermined direction (for example, in the clockwise direction in FIG. 11), the corner portion interferes with the inner portion of the engaging concave groove 12 and cannot rotate. On the other hand, when the chamfered portions 20c and 20c are formed at the corners in the diagonal direction, the length between the corner portions is the length Lz between the chamfered portions 20c and 20c, and the length Lz is engaged with the concave. By making the vertical width d2 of the inner portion of the groove 12 smaller (Lz <d2), the rotation is possible (see FIG. 11B). The chamfered portions 20c and 20c may be formed at two pairs of corners facing each other in the diagonal direction of the head 20, that is, at four corners of the entire circumference, and in that case, the fixing screw 18 may be formed in either direction. Even if it is rotated, the corner portion does not interfere with the inner portion of the engaging concave groove 12.

The head 20 of the fixing screw 18 is fitted into the engaging groove 12, and the screw shaft portion 19 projects forward from the rail 11. In that state, the head 20 is as shown in FIG. It is possible to switch between the disengagement posture and the engagement posture by rotating the screw shaft portion 19 of the portion 20. In the disengagement posture of the fixing screw 18, as shown in FIG. 11A, the long side portions 20b, 20b of the head portion 20 are arranged in the direction along the left-right direction, and the head portion 20 is engaged with the engaging concave groove 12. In the engaged posture, the long side portions 20b and 20b of the head portion 20 are arranged in the vertical direction as shown in FIG. 11 (c). The head portion 20 is restricted by contact with the upper and lower ridges 14 and 14 of the opening of the engaging concave groove 12 at the short side portions 20a and 20a so as to be engaged so as not to come out into the engaging concave groove 12. It has become. FIG. 11B shows a case where the fixing screw 18 is in an intermediate posture between the regulation release posture and the regulation posture. In this intermediate posture, the chamfered portions 20c and 20c of the head 20 are engaged recessed grooves. It is designed so that it does not interfere with the upper and lower surfaces of the inner part of 12.

Further, in the engaging groove 12 of the rail 11, a detent member 24 made of resin, metal, or the like is arranged around the fixing screw 18. In the detent member 24, when the fixing screw 18 is engaged by the head 20 in the engaging posture in the engaging groove 12 of the rail 11, the fixing screw 18 rotates in the disengaging posture. It is a member for regulating the. Specifically, as shown in FIG. 10, the detent member 24 is a rectangle extending in the same direction from a disk-shaped base portion 24a (base portion) and a portion of the outer periphery of the base portion 24a facing the diameter direction in parallel with each other. It consists of a pair of plate-shaped regulating portions 24b and 24b. The base portion 24a is sandwiched between the nut member 28, which will be described later, and the front surfaces of the rails 11 (front surfaces of the protrusions 14, 14) like a washer, and is used to prevent the nut member 28 from loosening from the fixing screw 18. Be done.

The distance between the two restricting portions 24b and 24b is slightly larger than the length Lx of the short side portion 20a of the head 20 of the fixing screw 18, and the width of each restricting portion 24b is the opening of the engaging groove 12 in the rail 11. The size is slightly smaller than the vertical width d1 of the portion. Further, an insertion hole 25 through which the screw shaft portion 19 of the fixing screw 18 protruding forward from the rail 11 can be inserted is formed in the central portion of the base portion 24a. Then, when the fixing screw 18 is engaged in the engaging groove 12 of the rail 11 by the head portion 20 in the engaging posture, the screw shaft of the fixing screw 18 is inserted into the insertion hole 25 of the base portion 24a of the detent member 24. The regulation portions 24b and 24b are inserted into the engaging groove 12 by inserting the portions 19, and the regulation portions 24b and 24b are brought into contact with the long side portions 20b and 20b of the head portion 20 in the engaging posture of the fixing screw 18. The head portion 20 is sandwiched between the long side portions 20b and 20b between the two regulation portions 24b and 24b. As a result, the fixing screw 18 in the engaging posture tries to rotate from the engaging posture to the unrotating posture, but the rotation is restricted by the contact with the opening of the engaging concave groove 12 in the rail 11. It is prevented by the regulation parts 24b and 24b. It is not necessary to provide a pair of regulating portions 24b, and only one side may be provided.

As shown in FIG. 5, each frame 35 is made of rectangular frame-shaped metal (for example, iron) arranged along the vertical plane in the front-rear direction, and is parallel to each other in the front-rear direction and in the vertical direction. The front and rear frame members 36 and 37 arranged along the above, and the upper and lower frame members 38 and 39 connecting the upper ends and the lower ends of the front and rear frame members 36 and 37, respectively. It has. The lower frame material 39 is in contact with the floor surface 9, and each frame 35 stands on the floor surface 9. Each of the frame materials 36 to 39 is made of, for example, a metal square cylinder having a rectangular cross section with a width of 16 mm, and the four frame materials 36 to 39 are integrated into a rectangular frame shape at the ends by welding, bolting, or the like. The heights of the left and right frames 35, 35 are the same as each other and are higher than the height positions of the upper rails 11 and 11, for example, 1800 mm, and the width in the front-rear direction is, for example, 350 mm. In each of the frames 35, the lower frame material 39 may be separated from the floor surface 9 without abutting on the floor surface 9. In that case, the frame 35 has a float construction structure supported only by the wall surface 1.

After that, the blind packing 22 is pushed into the engaging groove 12 of each rail 11 from the front opening of the engaging groove 12, and the head V1 of each mounting screw V is hidden by the blind packing 22. When the head V1 of the mounting screw V is concealed in this way, even if the rail 11 is partially visible from the front side, the mounting screw V cannot be seen, and the rail 11 only looks like a part of the wall. The appearance and design are ensured.

Further, in the engaging groove 12 of each rail 11 to which the blind packing 22 is attached, the fixing screw 18 is inserted and engaged at a predetermined position where the nut member 28 is to be attached. At that time, the fixing screw 18 is set so that the long side portions 20b, 20b of the head portion 20 are in the left-right direction (the short side portions 20a, 20a are in the vertical direction), and the head portion 20 is engaged with the rail 11. It is inserted into the groove 12 from the opening on the front side, and the screw shaft portion 19 thereof is projected from the opening on the engaging concave groove 12 to the front side. Since the length Lx of the short side portion 20a of the head portion 20 of the fixing screw 18 is smaller than the vertical width d1 of the opening of the engaging groove 12, the fixing screw 18 can be easily and smoothly inserted. Further, since the fixing screw 18 inserted in this way is in the disengagement posture (see FIG. 11A) and can move in the engaging concave groove 12 in the left-right direction, the position thereof is necessary.
