Description

The present invention relates to shelf columns applicable to wall-mounted shelves.

Conventionally, brackets have been attached to a base frame fixed to a wall, attachments have been attached to these brackets, and various members such as shelves and pipes used for suspension of articles can be attached via these attachments. Wall-mounted shelves (system racks) are known.

The applicant fixes a rail extending in the left-right direction (width direction) to the wall, and fixes each shelf pillar to the wall with a plurality of shelf columns arranged at positions separated from each other in the width direction. As a result, a wall-mounted shelf that constitutes a base frame with these rails and shelf columns has been devised and commercialized (see Patent Document 1 and Non-Patent Document 1 below).

JP-A-2007-105273 (Patent No. 4105720) Fujiyama Co., Ltd., "Fit Rack Catalog vol.3-b", page 7, [online], December 2019, Fujiyama Co., Ltd., [Search on May 10, 2nd year of Reiwa], Internet <URL: http: / /fitrack.jp/product/>

By the way, since the shelf pillar constituting the base frame is one long metal product, there is a problem that it is heavy, takes time and effort at the time of packing and construction, and the delivery cost is high. In addition, a large load acts locally on the wall on which a heavy shelf pillar is attached, and it may not be applicable if the wall has a low load capacity.

The present invention has focused on such a point, and a main object thereof is to provide a shelf pillar for a wall-mounted shelf that can solve the problems of a conventional metal shelf pillar caused by its long and heavy weight. It is in.

That is, the shelf pillar for a wall-mounted shelf according to the present invention constitutes a wall-mounted shelf in a state of being attached to the wall together with a rail which is a cross rail, and has two types of resin shelf pillar elements, an upper shelf pillar element and an upper shelf pillar element. It can be used as one shelf pillar in a state where the lower shelf pillar elements are connected in the height direction. In the wall-mounted shelf column according to the present invention, the elastic claws provided on either the upper shelf column element or the lower shelf column element are elastically engaged in the holes formed in the other shelf column element. It is characterized in that the lower end surface of the upper shelf column element and the upper end surface of the lower shelf column element are in contact with each other in the combined connected state.

Any of such shelf columns for wall-mounted shelves according to the present invention can be used as one shelf column in a state where the upper shelf column element and the lower shelf column element made of resin are connected in the height direction. Because it is a thing, the weight as one shelf pillar is lighter than the conventional shelf pillar which was one long metal product, and the weight of each shelf pillar element is even lighter. In addition to improving the handleability at the time of construction, the length is shortened by packing in the form of the upper shelf pillar element and the lower shelf pillar element, the labor at the time of packing is reduced, and the delivery cost is also reduced. In addition, since a relatively lightweight resin shelf is attached to the wall, the load acting on the wall to which the shelf is attached is compared to the case where one long metal product shelf is attached to the wall. There is also an advantage that the wall is not required to have a high load capacity and the wall that can be constructed is not excessively limited.

In particular, in the shelf pillar for a wall-mounted shelf according to the present invention, an elastic claw provided on one of the upper shelf pillar element and the lower shelf pillar element adjacent in the height direction is provided in the hole of the other shelf pillar element. The shelf column elements can be connected only by elastically engaging with the shelf column elements, and the workability is excellent because a dedicated joint member is not required. Moreover, the shelf column elements (upper shelf column element and lower shelf column element) are excellent. ) Are in contact with each other on the lower end surface of the upper shelf column element and the upper end surface of the lower shelf column element, so that a stable connected state can be maintained. Such resin-made shelf columns for wall-mounted shelves are unprecedented and epoch-making.

Further, in the present invention, if the elastic claw has a shape in which the shelf column elements are connected to each other and does not appear as a protrusion protruding outward at the connecting portion, the elastic claw may be unexpectedly caught by another member. It is possible to prevent / suppress, and it is also possible to prevent / suppress the problem that another member hits the elastic claw in the elastically engaged state and the elastically engaged state is unintentionally released.

If the wall-mounted shelf pillar according to the present invention is provided with a plurality of bracket mounting slits in the height direction on the front walls of the upper shelf pillar element and the lower shelf pillar element, the height position selected by the user. Brackets can be attached using the slits in the above, and optional parts such as shelves can be set at arbitrary height positions selected by the user via the brackets.

If the wall-mounted shelf pillar according to the present invention has a hooking portion that can be hooked from above to the rail fixed to the wall, the shelf for the rail fixed to the wall before the shelf pillar is provided. Positioning of the pillar can be performed smoothly and accurately by a simple operation of hooking the hooked portion on the rail.

According to the present invention, there is a novelty that has never been conceived so far that the upper shelf pillar element and the lower shelf pillar element, both of which are made of resin, are used as one shelf pillar in a state of being connected in the height direction. By adopting such a technical idea, it is possible to provide a shelf pillar for a wall-mounted shelf that can solve various problems that have occurred in the conventional long and heavy metal shelf pillar.

Therefore, for example, when the rail 1 having a width dimension of 450 mm is applied, the rail 1 is divided by the groove 13 formed at the position of 450 mm. When divided at the groove 13, it becomes at least two divided rails, one divided rail is the rail actually used (used rail 1), and the other divided rail is scheduled to be actually used. It becomes a rail that has not been used (disposal rail). In the present embodiment, characters (illustration example) indicating the length (width dimension) of the used rail 1 after division to the portion (remaining portion) that is at least in the vicinity of the groove 13 and becomes the used rail 1 after being divided by the groove 13. Then, W450, W600) is engraved. In the present embodiment, the total length of the rail before division is set to 750 mm, and a character (W700 in the illustrated example) indicating the total length of the rail before division is engraved on one end of the rail. In the rail 1 of the present embodiment, characters indicating these width dimensions are engraved on the back surface of the upright wall 11 (see FIG. 3C). In particular, the rail 1 according to the present embodiment has characters (W450, W600 in the illustrated example) indicating the width dimension after division among the engraved portions (formation portions of the length engraved portion 14) of the characters indicating the width dimension. It is set in a portion that is in the vicinity of the groove 13 and becomes the rail 1 to be used after being divided by the groove 13. As a result, the length of the rail 1 used can be intuitively grasped before and after the division.

Further, on the forward surface of the upright wall 11 of the rail 1, a recess 15 capable of accommodating a fixing tool (fixing metal fitting P described below in the present embodiment) used for fixing the rail 1 to the wall W is formed. (See FIGS. 2 and 3 (b)).

As shown in FIGS. 5 and 6, the fixing bracket P can be fixed in a state where the fixing bracket P is pressed from the front against a wall W having no base such as gypsum board. 5 is an overall external view of the fixing bracket P, FIG. 6A is a front view of the fixing bracket P, and FIGS. 6B and 6C are arrows in the A1 direction of FIG. 6A. It is an A2 direction arrow view. The fixing metal fitting P of the present embodiment is substantially a disk-shaped surface contact main body P1 that is directly or indirectly pressed against the wall W, and from the periphery of the surface contact main body P1 to the surface contact main body P1. It is a metal integrated product that is integrally provided with three insertion claws P2 that project in the direction of bending 90 degrees, and can be fixed in a state of being pressed in a predetermined pressing direction. The three insertion claws P2 are evenly arranged around the surface contact main body portion P1, each of which has an acute-angled tip portion and a sawtooth-shaped multi-stage return P3 (illustration example) from the tip portion to the base end portion. Then, it has two steps) and has an acute angle shape. In the present embodiment, the fixing metal fitting P formed by performing an appropriate processing such as press working on a steel sheet having a thickness of 1 mm is applied. Further, in the central portion of the surface contact main body portion P1 of the fixing metal fitting P, a through hole P5 through which another fixing tool such as a tapping screw N can be inserted is formed. The diameter of the outer peripheral portion of the surface contact main body portion P1 is 16 mm, and the diameter of the through hole P5 is 3.2 mm. The length from the base end to the tip end of each insertion claw P2 is 16 mm, the maximum width of the return portion of each insertion claw P2 is 3 mm, and the minimum width is 2 mm.

A recess 15 capable of accommodating such a fixing bracket P is provided on the forward facing surface of the upright wall 11 of the rail 1 (see FIGS. 2, 3 (b), 4 (b), and 4 (c)). Specifically, recesses 15 are provided near both ends of the rail 1, three recesses 15 are provided between the recesses 15 at both ends at intervals of 150 mm or 217.5 mm, and a total of five recesses 15 are provided in the longitudinal direction of the rail 1. It is set to line up multiple lines along. The height position of the recess 15 is set so as not to overlap the hooking wall 12 when the rail 1 is viewed from the front.

The recess 15 has a main recess 151 that can accommodate the surface contact main body P1 of the fixing bracket P, and an insertion claw guide recess 152 that guides the insertion position of the insertion claw P2 of the fixing bracket P. The recessed dimension of 151 is set shallower than the recessed dimension of the insertion claw guide recess 152. The insertion claw guide recess 152 is arranged at an equal pitch (120 degrees) in the circumferential direction on the peripheral edge of the surface contact main body P1. The thickness dimension of the upright wall 11 (dimension in the front-rear direction D1) of the rail 1 is 3 mm, and the bottom of the main recess 151 of the recesses 15 is set at a position 1.1 mm from the forward surface of the upright wall 11 and inserted. The bottom of the claw guide recess 152 is set at a position 2.7 mm from the forward facing surface of the upright wall 11. That is, the bottom of the insertion claw guide recess 152 is set to a thickness (thickness 0.3 mm) that can be penetrated by the insertion claw P2. Further, in the central portion of the main recess 151, a screw guide recess 153 is formed to guide the position where the tapping screw N, which is a fixing tool different from the fixing metal fitting P, is inserted. The screw guide recess 153 has a bottom portion set to be as thin as the insertion claw guide recess 152, and a counterbore portion for accommodating the head of the tapping screw N.

Before fixing such a rail 1 to the wall W, the width dimension of the rail 1 is selected and selected in advance, and the rail 1 is divided by a groove 13 provided at a position corresponding to the selected length. Of course, the entire length of the rail 1 can be used as it is without being divided. The process of fixing the rail 1 to the wall W is performed by pressing the back surface (rear facing surface) of the upright wall 11 against the wall W with the rail 1 in a horizontal posture and using the fixing bracket P or the tapping screw N. That is, when the wall W has no base, it is fixed by using the fixing metal fitting P, and when the wall W has a base, it is fixed by using the tapping screw N. The process of fixing the rail 1 using the fixing bracket P is completed by inserting the fixing bracket P into each recess 15. When the fixing bracket P is inserted into the recess 15, the tip of the insertion claw P2 breaks through the insertion claw guide recess 152 and pierces the wall W as it is. Surface contact of the fixing bracket P When the fixing bracket P is pressed to the position where the main body P1 is completely accommodated in the main recess 151, the three insertion claws P2 are pierced inside the wall W by a predetermined distance, which is good. The fixed state can be maintained, and the rail 1 can be fixed in a state of being sandwiched between the wall W having no base and the fixing metal fitting P. On the other hand, when the rail 1 is fixed to the wall W by using the tapping screw N without using the fixing metal fitting P for the wall W having the base, the tapping screw N is inserted into the screw guide recess 153 of the recesses 15. , Screw it into the wall W as it is.

By the above procedure, the shelf column 2 can be positioned while being hooked on the rail 1 fixed to the wall W.

As shown in FIGS. 7 and 8, in the shelf column 2 according to the present embodiment, the upper shelf column element 3A and the lower shelf column element 3B, which are two types of resin shelf column elements, are connected in the height direction. It can be used as one shelf pillar 2 in the state. As shown in FIGS. 8A and 9, the upper shelf column element 3A has a front wall 31, a pair of left and right side walls 32 protruding rearward from both side edges of the front wall 31, and a back surface (rearward) of the front wall 31. The surface) has a central rib wall 33 projecting rearward from the central portion of the front wall 31 in the width direction D2 over substantially the entire length. 9 (a) is a front view of the upper shelf pillar element 3A, and FIGS. 9 (b) and 9 (c) are an A1 direction arrow view (plan view) and an A2 direction arrow view (bottom view) of the same figure (a). ). The thickness dimension of the front wall 31 (dimension in the front-rear direction D1) is 2.3 mm, the thickness dimension of the side wall 32 (dimension in the width direction D2) is 5 mm, and the thickness dimension of the central rib wall 33 (dimension in the width direction D2). Dimensions) is 8 mm. The amount of protrusion (protrusion dimension) of the side wall 32 and the central rib wall 33 to the rear with respect to the front wall 31 is the same. It is set on a flat surface.

A large number of slits 34 for mounting brackets are opened in the front wall 31 at a predetermined pitch in the height direction. In the present embodiment, a column in which vertically long slits 34 are formed in a pair of left and right (two vertical rows) at the same height position is shown, but one in which slits 34 are formed in one vertical row or three or more rows is adopted. It doesn't matter. Further, in the central portion of the front wall 31 in the width direction D2, a plurality of screw insertion holes 35 are provided in the height direction at positions that do not overlap the slit 34. The screw insertion hole 35 is a hole that penetrates from the forward surface of the front wall 31 to the protruding tip surface of the central rib wall 33. The screw insertion hole 35 also includes a counterbore exposed on the front facing surface of the front wall 31. A screw insertion hole 35 is provided at a position near the upper end portion, a center position in the height direction, and a position near the lower end portion of the upper shelf column element 3A of the present embodiment, respectively.

Further, as shown in FIG. 10A, the upper shelf column element 3A of the present embodiment has a height of a receiving portion 36 that can be accommodated in a state where the fixing bracket P is hooked on the protruding tip surface of the central rib wall 33. Multiple are provided in the direction. 10 (a) is a cross-sectional view taken along the line d1-d1 of FIG. 9 (a). In the present embodiment, the receiving portion 36 is formed at a position communicating with the screw insertion hole 35. The receiving portion 36 is a concave groove capable of covering and accommodating the fixing metal fitting P fixed to the wall W from the front side of the wall W at a time before the process of attaching the shelf pillar 2 to the rail 1.

The upper shelf column element 3 is provided with an elastic claw 37 projecting downward at the lower end portion, and is provided with an engagement hole 38 at the upper end portion with which the elastic claw 37 is engaged. As shown in FIGS. 9 (a) and 11 (a), the elastic claw 37 projects further downward from the flat lower end surface of both side walls 32, and the engaging protrusion 371 (return portion) at the tip portion protrudes outward. It is a suitable shape. The shelf column element 3 projects further downward from the lower end surface of the central rib wall 33 between the pair of left and right elastic claws 37, and the upper shelf column element 3A and the lower shelf column element 3B are connected in the height direction. A rib reinforcing portion 39 that comes into contact with the rearward surface of the front wall 31 of the lower shelf column element 3B is provided (see FIG. 10 (a)). The tip surface (lower end surface) of the elastic claw 37 and the rib reinforcing portion 39 is set to be a flat surface in the horizontal direction.

The engagement hole 38 is a hole that penetrates in the thickness direction (width direction D2) of the side wall 32 at a position separated downward by a predetermined distance from the upper end surfaces of the side wall 32. The upper end surface of the central rib wall 33 is set at a position lower than the engagement hole 38 (see FIG. 10A).

On the other hand, as shown in FIGS. 8 (b), 10 (b) and 11 (b), the lower shelf column element 3B has the above-mentioned elastic claw 37 and rib reinforcement as compared with the upper shelf column element 3A. The only difference is that the portion 39 is not provided, and the other structures and shapes are the same as those of the upper shelf column element 3A.

When two such upper shelf column elements 3A and lower shelf column elements 3B are arranged side by side in the height direction and brought close to each other as shown in FIG. 12, elastic claws provided at the lower end of the upper shelf column element 3A are relatively close to each other. When the engaging protrusion 371 at the tip of 37 hits the upper end surface 3T of the lower shelf column element 3B and the shelf column elements 3A and 3B are brought closer to each other, the elastic claw 37 becomes the side wall 32 of the lower shelf column element 3B. Elastically deforms while in contact. When the shelf column elements 3A and 3B are brought closer to each other as they are, the engaging protrusion 371 of the upper shelf column element 3A reaches the engaging hole 38 of the lower shelf column element 3B and elastically returns to fit into the engaging hole 38. Engage in. By engaging the elastic claw 37 with the engagement hole 38 in this way, the upper shelf column element 3A and the lower shelf column element 3B can be connected, and one shelf column 2 can be formed. In this connected state, the lower end surface 3D of the upper shelf column element 3A and the upper end surface 3T of the lower shelf column element 3B are in contact with each other (see FIG. 7B). Further, in this connected state, the front-facing surface of the rib reinforcing portion 39 provided between the elastic claws 37 of the upper shelf column elements 3A is in surface contact with the rear-facing surface of the front wall 31 of the lower shelf column elements 3B. (See Fig. 7 (b)). Further, in the shelf column 2 of the present embodiment, when the upper shelf column element 3A and the lower shelf column element 3B are connected and a force acts in the direction of separating the shelf column elements 3A and 3B from each other, the elastic claw 37 By catching the engaging protrusion 371 (return portion) at the tip portion of the above in the engaging hole 38, the elastic claw 37 exerts a retaining function of preventing the elastic claw 37 from coming off from the engaging hole 38. FIG. 7B is a front view of the shelf pillar 2 and is an enlarged view showing a connecting portion between the upper shelf pillar element 3A and the lower shelf pillar element 3B. When the operator applies an operating force to press the elastic claw 37 inward using an appropriate jig, the elastic claw 37 is disengaged from the engagement hole 38, and the shelf column elements 3A and 3B are separated from each other in that state. When pulled to, the connection state between the shelf pillar elements 3A and 3B can be released.

Further, the upper shelf column element 3A of the present embodiment is provided with a hooking portion 3H at the upper end portion that can be hooked on the hooking wall 12 of the rail 1 from above. The hook portion 3H is located in the side wall 32 at a position separated from the engagement hole 38 in the height direction (direction closer to the center side in the height direction than the engagement hole 38) by a predetermined distance from the front wall 31 side toward the rear. It has a shape (shape of the hook groove 13) that opens in a direction that gradually inclines toward the center in the height direction. The inclination angle of the hooking portion 3H corresponds to the protruding inclination angle of the hooking wall 12.

Therefore, among the shelf columns 2 in which the shelf column elements 3A and 3B having such hooking portions 3H are connected to each other, the hooking portion 3H of the upper shelf column element 3A can be hooked on the hooking wall 12 of the rail 1 from above. In the present embodiment, of the side wall 32 of the upper shelf column element 3A, the part above the hooking portion 3H (the side away from the center of the side wall 32 in the extending direction (height direction) with respect to the hooking portion 3H as a boundary). The dimension (depth dimension) of the front-rear direction D1 of (the portion) is set smaller than the other portions by the dimension (thickness dimension) of the upright wall 11 of the rail 1 in the front-rear direction D1. Therefore, when the rail 1 is hooked on the hooking wall 12 on the hooking portion 3H, the entire rearward surface of the side wall 32 below the hooking portion 3H (most of the side wall 32) is covered with the upright wall 11 of the rail 1. It can be brought into contact with the wall W to be fixed. At the upper end portion of the upper shelf column element 3A provided with the hook portion 3H, the central rib wall 33 is set to have a shape cut into the same shape as the opening edge of the hook portion 3H (see FIG. 10). That is, the central rib wall 33 extending along the height direction of the upper shelf column element 3A does not extend to a position beyond the hook portion 3H. 8 (b), 10 (b), and 11 (b) are lower shelf column elements 3B, respectively, and correspond to FIGS. 8 (a), 10 (a), and 11 (a). It is a figure which shows. FIG. 11 (a) shows a state in which the upper shelf pillar element 3A is hooked on the rail 1, but since it is not assumed that the lower shelf pillar element 3B is hooked on the rail 1, FIG. 11 (b) shows. Rail 1 is not shown.

The procedure for setting the base frame Y of the wall-mounted shelf X on the wall W using the above parts (rail 1, shelf pillar 2, fixing bracket P) is as follows.

First, when adjusting the rail 1 to a predetermined length, the character indicating the length engraved on the back surface of the upright wall 11 of the rail 1 (length engraved portion 14) is used as a clue, and the vicinity of the length engraved portion 14 is used as a clue. The rail 1 is divided by the groove 13 provided in. This division work can be done by hand. With the divided used rail 1 or the upright wall 11 of the rail 1 used as it is without being divided against the wall W, the rail 1 is attached to the wall by the above-mentioned fixing process using the fixing bracket P or the tapping screw N. Fix to W. In particular, when the rail 1 is fixed to a wall W having no base like a gypsum board with a fixing bracket P, the three insertion claws P2 provided on each fixing bracket P at a pitch of 120 degrees are at different angles. A good fixed state can be maintained by piercing the inside of the wall W. If the fixing point of one rail 1 to the wall W can be distinguished between the part with the base and the part without the base, tapping screw N is used for the part with the base and fixed to the part without the base. The metal fitting P may be used. That is, when fixing one rail 1 to the wall W at a plurality of places (up to 5 places in the illustrated example), for example, three places are fixed with tapping screws N and the remaining two places are fixed with a fixing bracket P. Aspects can also be adopted.

Next, a required number of shelf columns 2 in which the upper shelf column element 3A and the lower shelf column element 3B are connected by the above procedure are prepared, and the upper end portion of each shelf column 2 (the upper end portion of the upper shelf column element 3A). The hooking portion 3H provided in the above is hooked on the hooking wall 12 of the rail 1 from above. If the place where the shelf pillar 2 is fixed to the wall W is a place where there is no base such as gypsum board, the receiving portion 36 (width) of the shelf pillar 2 is before the shelf pillar 2 is hooked on the rail 1. The fixing bracket P is pierced into the place where the receiving portion 36) provided on the protruding tip surface of the central rib wall 33 protruding rearward from the central portion of the direction D2 is pierced, and the surface contact main body portion P1 of the fixing bracket P contacts the wall W. Push it in to the position where you want to fix it. As a result, the fixing bracket P is housed in the receiving portion 36 in a state where the shelf pillar 2 is hooked on the rail 1 and supported. Subsequently, when the tapping screw N is inserted from the front side into the screw insertion holes 35 provided in the front walls 31 of the shelf pillar elements 3A and 3B constituting the shelf pillar 2, the tapping screw N is accommodated in the receiving portion 36. It enters the wall W while being screwed into the through hole P5 formed in the central portion of the surface contact main body portion P1 among the fixing metal fittings P (see FIG. 10). By the above processing, the shelf pillar 2 can be fixed to the wall W at the fixing location.
On the other hand, if the fixing point of the shelf pillar 2 to the wall W is a place having a base (a place where a screw works), the shelf pillar 2 is fixed to the wall W by using only the tapping screw N without using the fixing metal fitting P. be able to. In this case, it is not necessary to push the fixing bracket P into the wall W to fix the shelf pillar 2 before hooking the shelf pillar 2 on the rail 1, and the shelf pillar 2 is configured after the shelf pillar 2 is hooked on the rail 1. The shelf pillar 2 is screwed to the wall W by inserting tapping screws N from the front side into the screw insertion holes 35 provided in the front walls 31 of the shelf pillar elements 3A and 3B from the front side and screwing them into the wall W. Can be done.

If the fixing point of one shelf pillar 2 to the wall W can be distinguished between the place with the base and the place without the base, only the tapping screw N is used for the place with the base, and the place without the base is used. May use the fixing bracket P and the tapping screw N. That is, when fixing one shelf pillar 2 to the wall W at a plurality of places (up to 6 places in the illustrated example), for example, three places are fixed only with tapping screws N, and the remaining three places are tapped with the fixing bracket P. A mode of fixing with a screw N can also be adopted.

By the above procedure, the base frame Y of the wall-mounted shelf X can be set in a state of being fixed to the wall W. Then, the bracket B is attached to an arbitrary bracket mounting slit 34 selected from the plurality of bracket mounting slits 34 formed on the front wall 31 of each shelf pillar element 3, and the shelf board T is attached to the bracket B via the attachment. By attaching the above, it becomes a wall-mounted shelf X on which an appropriate item or the like can be placed on the shelf board T.

The bracket B used in the present embodiment is an integrally molded product made of synthetic resin, and as shown in FIG. 13, it is inserted into the bracket mounting slits 34 of the shelf column elements 3A and 3B on the base end side to be hooked. A plurality of hook claws B1 (three hook claws B1 arranged in the height direction in the illustrated example) are formed, and a long arm portion B2 is extended from the base end side to the tip end side thereof. 13 (a) and 13 (b) are overall external views of the bracket B as viewed from different directions. The hook claw B1 has a downward L-shape like a general-purpose steel plate-shaped bracket. Of the arm portions B2 exposed to the outside when the hook claw B1 is hooked on the bracket mounting slit 34 of the shelf pillar element 3, the portion that is in contact with or close to the shelf pillar elements 3A and 3B and is one step from the top. The thickness of the portion below the hook claw B1 of the eye and the portion of the lower edge of the arm portion B2 extending from the base end of the arm portion B2 to a predetermined position along the extending direction are set to be larger than those of the other regions. ing. Further, in the arm portion B2, a plurality of holes B3 (six holes B3 in the illustrated example) are formed in a row along the longitudinal direction thereof. Each hole B3 is formed in a square shape. The intervals between the holes B3 in the arm portion B2 are all equal except that the space between the first and the second from the proximal end side is slightly narrowed. The number and position of holes B3 formed in the arm portion B2 can be arbitrarily set.

As described above, the wall-mounted shelf shelf column 2 according to the present embodiment is one shelf column in a state where two upper shelf column elements 3A and lower shelf column elements 3B, both of which are made of resin, are connected in the height direction. Since it can be used as 2, the weight as one shelf pillar is lighter than that of the conventional shelf pillar which was one long metal product, and further, the upper shelf pillar element 3A and the lower side Since the weight of each shelf pillar element of the shelf pillar element 3B is even lighter, the handleability at the time of construction is improved, and the length is shortened by packing in the form of each shelf pillar element, which saves time and effort during packing. It will be reduced and the delivery cost will be cheaper. In addition, since the relatively lightweight shelf pillar 2 made of resin is attached to the wall W, the shelf pillar 2 according to the present embodiment is compared with the case where one long metal product shelf pillar is attached to the wall. There is also an advantage that the load acting on the wall W to which the wall W is attached is reduced, a high load capacity is not required for the wall W, and the wall W that can be constructed is not excessively limited.

Further, in the present embodiment, one upper shelf pillar element 3A or lower shelf pillar element 3B (preferably lower shelf pillar element 3B) is used for a wall-mounted shelf as it is without being connected to another shelf pillar element. It can also be used as a shelf pillar 2. When the shelf column 2 is configured with only one upper shelf column element 3A, an appropriate cap is attached to the lower end portion of the upper shelf column element 3 to avoid exposure of the elastic claw 37, which is good. It becomes possible to keep the appearance.

In addition, the wall-mounted shelf shelf column 2 according to the present embodiment can only perform the work of elastically engaging the elastic claw 37 of the upper shelf column element 3A with the hole (engagement hole 38) of the lower shelf column element 3B. The shelf column elements 3A and 3B can be connected to each other, and since a dedicated joint member is not required, workability is excellent. Moreover, with the shelf column elements 3A and 3B connected to each other, the upper shelf column element is relatively high. Since the lower end surface 3D of 3A and the upper end surface 3T of the lower shelf column element 3B are in contact with each other, a stable connection state can be maintained.

Further, in the wall-mounted shelf column 2 according to the present embodiment, the elastic claw 37 appears as a protrusion protruding outward at the connecting portion in a state where the upper shelf column element 3A and the lower shelf column element 3B are connected. Since the shape is set to be non-existent, it is possible to prevent / suppress a situation in which another member is unexpectedly caught on the elastic claw 37, and the other member hits the elastic claw 37 in the elastic engagement state and is in the elastic engagement state. It is also possible to prevent / suppress problems that are unintentionally released.

The wall-mounted shelf column 2 according to the present embodiment is selected by the user because a plurality of bracket mounting slits 34 are provided in the front walls 31 of the upper shelf column element 3A and the lower shelf column element 3B in the height direction. The bracket B can be attached by using the slit 34 at the height position, and the optional parts such as the shelf board T can be set at an arbitrary height position selected by the user via the bracket B.

Further, since the wall-mounting shelf pillar 2 according to the present embodiment has a hooking portion 3H that can be hooked from above to the rail 1 fixed to the wall W prior to the shelf pillar 2, the hooking portion is provided. By hooking the 3H to the rail 1 from above, the shelf column 2 can be positioned smoothly and accurately with respect to the rail 1.

The present invention is not limited to the above-described embodiment. For example, the shape and number of elastic claws can be appropriately changed, and the shape and number of holes (engagement holes) can also be appropriately changed according to the elastic claws.

It can also be used as one shelf pillar in a state where three or more resin shelf pillar elements are connected in the height direction. For example, two or more upper shelf pillar elements 3A exemplified in the above embodiment are connected to each other, and one lower shelf pillar element is connected to the lowermost upper shelf pillar element 3A among the plurality of upper shelf pillar elements 3A. It is possible to use 3B as one shelf pillar 2 in a state of being connected in the height direction. In this case, the connection process between the upper shelf column elements 3A is performed by elastically engaging the elastic claw 37 of the relatively upper shelf column element 3A with the engagement hole 38 of the relatively lower shelf column element 3B. It can be done easily and smoothly.

Further, it is possible to connect the shelf column elements to each other by providing elastic claws at the upper end of the lower shelf column element and elastically engaging the elastic claws with the engagement holes formed at the lower end of the upper shelf column element. It may be a configuration. That is, the elastic claws may be provided at least on either the upper shelf column element or the lower shelf column element, and the engagement hole is also formed on at least one of the upper shelf column element or the lower shelf column element. Is enough. Therefore, in the above-described embodiment, the embodiment in which the engagement hole is formed at the upper end portion of the upper shelf column element is exemplified, but the engagement hole is omitted because it is a hole that does not contribute to the connection with the lower shelf column element. You can also do it.

Further, the upper shelf pillar element and the lower shelf pillar element are all resin shelf pillar elements having the same shape, and one such shelf pillar element is connected in the height direction. It can also be used as a shelf pillar. If all the shelf pillar elements have the same shape, the complexity at the time of construction can be reduced and it is advantageous in terms of manufacturing cost as compared with the embodiment in which the upper shelf pillar element and the lower shelf pillar element are used separately. If all the shelf pillar elements are provided with elastic claws protruding downward at the lower end portion, the elastic claws are exposed at the lower end portion of the lowermost shelf pillar element. In this case, by attaching a cap to the lower end of the bottom shelf column element, the parts (elastic claws) that protrude below the lower end surface of the shelf column element are avoided from being exposed, and a good appearance is maintained. be able to. Similarly, if all the shelf column elements have elastic claws protruding upward at the upper end, the elastic claws will be exposed at the upper end of the uppermost shelf column element, so that the uppermost shelf By attaching a cap to the upper end of the column element, it is possible to avoid exposure of parts (elastic claws) protruding above the upper end surface of the shelf column element and maintain a good appearance.

If the rails that make up the base frame together with the shelf pillars do not have a part for hooking the shelf pillars, those that do not have a hooking portion for the shelf pillars can be applied. Further, the hooking portion may not be provided on all the shelf pillar elements, but may be provided only on any of the shelf pillar elements (in the above-described embodiment, the hooking portion is provided only on the upper shelf pillar element, and the lower part is provided. The side shelf pillar element is not provided with a hooking part).

Further, it is also possible to use one shelf pillar element as it is as a shelf pillar for a wall-mounted shelf without connecting a plurality of shelf pillar elements to each other. In this case, by attaching a cap to the end of the upper end or lower end of the shelf column element provided with elastic claws, a part (elasticity) that protrudes above the upper end surface or below the lower end surface of the shelf column element. It is possible to avoid exposure of the nails) and maintain a good appearance.

The fixing tool for fixing the shelf pillar to the wall may be something other than the above-mentioned fixing metal fittings and tapping screws.

The shelf pillar according to the present invention can also be attached to a wall other than gypsum board.

In addition, the specific configuration and processing content of each part are not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
