  In this specification, “left and right”, “up and down”, and “front and rear” refer to directions in a state where a support body is installed and a board (door) is closed. In the present invention, “on a shelf” may be on a shelf on which products are displayed, and usually means on an uppermost shelf (top plate) of a multi-stage display shelf. In this case, the space on the shelf refers to the space between the uppermost shelf (top plate) and the ceiling. Replenishment products are usually stocked on multi-stage display shelves used in mass retailers, specialty stores for medicines and daily miscellaneous goods, and the like. The strut body of the present invention is installed at the front part on the shelf and supports a board-shaped door.When the door is closed, the stock product is blindfolded, and when the stock product is taken out, the door is opened. The door is opened and the open state of the door is maintained. Note that product information is usually displayed on the surface of the board-shaped door.

  Next, a support body according to the first embodiment of the present invention will be described with reference to FIGS. The support body 10 is installed in front of the uppermost shelf 22f of the seven-stage product display shelf 20, and opens and closes a front opening of a space 40 on the shelf. In FIG. 1, the board-shaped door 9 is depicted as being transparent, but an opaque one is usually used. The ceiling not shown in FIG. 1 is located immediately above the column 10.

  The support body 10 includes a pair of left and right resin members each having a fixed-side support portion 2 having a lower end fixed to the front end (installation portion) of the uppermost shelf 22f, and a movable support portion 3 that is movable to the fixed-side support portion 2. Things. Since the pair of right and left columns 10 have the same shape and the same function, one column 10 will be described.

  The fixed-side support portion 2 is formed by forming a pair of symmetric locking grooves 23A on both sides of a medium-sized member. The height of the fixed-side support 2 is substantially the same as the height of the door 9 because the movable support 3 that supports the board-shaped door 9 is fitted. A lower locking portion 22 fixed to the installation portion is formed below the fixed support 2. The lower locking portion 22 has a locking shape that is fitted to the front shape of the uppermost shelf 22f by a spring bias. Thereby, it can be fitted and fixed to the front end of the uppermost shelf 22f. The upper portion of the main body in which the locking groove 23A is formed has a round shape corresponding to the shape of the locking groove 23A.

Locking groove 23A has been formed on the shaped notched sides of square material thickness W, the partition wall 231 in the center, the groove depth w ₁ is formed symmetrical. The locking groove 23 </ b> A includes a long vertical groove portion (long vertical portion) 23 extending vertically, a connecting groove portion (connecting portion) 25 continuous with the upper end of the long vertical groove portion 23 and slightly extending rearward, and a rear end of the connecting groove portion 25. It is a modified continuous groove composed of a short vertical groove portion (short vertical portion) 26 that is continuous and extends in the vertical direction, and a short horizontal groove portion (short horizontal portion) 24 that is continuous with the lower end of the short vertical groove portion 26 and extends rearward. The long vertical groove portion 23 is a linear groove formed in a front portion that occupies most of the height of the fixed-side column portion 2. The lower end of the long vertical groove 23 is one end of the locking groove 23A. The groove depth of the long vertical groove portion 23 is such a depth that one of the grooves is such that the locking projection 35 is loosely fitted and does not fall off during movement, and is about 5 mm to 10 mm.

  The connecting groove 25 is a groove connecting the long vertical groove 23 and the short vertical groove 26, and has a round shape projecting upward in this example. When the locking projection 35 is located on the bottom wall 241 at the lower end of the short vertical groove 26, the radius is preferably a part of a circle centered on the axis of the locking projection 35. Further, the connecting portion between the connecting groove portion 25 and the short vertical groove portion 26 is located above the connecting portion with the long vertical groove portion 23. Due to such a shape of the connecting groove 25, the locking projection 35 of the movable support portion 3 moves from the long vertical groove 23 to the short vertical groove 26 via the connecting groove 25, or from the short vertical groove 26 to the connecting groove 25. When it moves to the long vertical groove portion 23, it becomes smooth.

  The short vertical groove 26 is a vertical groove having a small height formed behind the long vertical groove 23 and above the long vertical groove 23. That is, the upper front part of the short vertical groove part 26 is continuous with the connecting groove part 25, and the lower rear part of the short vertical groove part 26 is continuous with the short horizontal groove part 24. For this reason, the short vertical groove portion 26 has a rear upper wall portion 251, a front lower wall portion 252, and a bottom wall portion 241. When the locking protrusion 35 of the movable support portion 3 is fitted into the short vertical groove portion 26 from the long vertical groove portion 23 via the connecting groove portion 25, it is guided by the rear upper wall portion 251 and the front lower wall portion 252 of the short vertical groove portion 26. , Bottom wall 241. Thereby, the board-shaped door 9 locked to the movable support part 3 can hold the opening closed.

  The short horizontal groove portion 24 is continuous with the lower portion behind the short vertical groove portion 26, and extends slightly rearward and downward. The rear end of the short lateral groove 24 is the other end of the locking groove 23A. By making the short lateral groove portion 24 slightly inclined backward, the back surface of the front plate 31 of the movable support portion 3 hits the small protrusion 27 extending upward from the upper end of the fixed side support portion 2, and the fixed side support portion 2 is horizontally moved. Posture can be. Thereby, the opening on the shelf can be held in the open state. As described above, the locking groove 23 </ b> A is formed by the three walls of the side walls and the partition wall, and is a continuous groove from the lower end of the long vertical groove 23 to the rear end of the short horizontal groove 24. I have. The groove 211 located on the rear side of the long vertical groove portion 23 of the fixed-side support portion 2 is not the locking groove 23A but a concave portion forming the rib structure 21. Thereby, weight can be suppressed while maintaining strength.

  The movable support portion 3 is a medium-sized rectangular case having a left and right side plates 33a and 33b, a front side plate 31, a top plate 36, and a bottom plate 37, the back surface of which is open. The upper left and right side plates 34a and 34b that are continuous with the left and right side plates 33a and 33b have a large depth dimension. Thereby, the installation of the locking projection 35 becomes possible. The formation position of the locking projection 35 on the movable support portion 3 is such that when the locking projection 35 is locked in the short vertical groove portion 26, the movable support portion 3 becomes substantially upright and a part of the fixed-side support portion 2. The position is such that the movable support 3 is substantially horizontal when the locking projection 35 is locked at the end of the short lateral groove 24. That is, the dimension between the locking projection 35 and the back surface of the front plate 31 of the movable support 3 is approximately the same as the height from the bottom wall 241 of the short vertical groove 26 of the fixed support 2 to the upper end of the small projection 27. Have. Thereby, the movable support unit 3 with the board 9 can take a posture lying from the state where the opening on the shelf is closed to the state where the movable support unit 3 opens the opening on the shelf.

The locking protrusion 35 is a round bar shaft facing the back surface of the left and right side plates 34a and 34b on the upper part of the movable support portion 3, the shaft diameter is slightly smaller than the groove width of the locking groove 23A, and the shaft length is , is slightly smaller than the groove depth w ₁ of the locking groove 23A. The locking projections 35 lock the left and right symmetrical locking grooves 23 </ b> A formed on both side surfaces of the fixed-side support 2 so as to sandwich the locking grooves 23 </ b> A from both sides. That is, the locking projection 35 can reciprocate from the lower end of the long vertical groove 23 to the rear end of the short horizontal groove 24 via the connecting groove 25. An upper locking piece 32a is formed at the upper end of the front side plate 31 of the movable support portion 3, and a lower locking piece 32b is formed at the lower end. The board 9 is installed on the upper locking piece 32a and the lower locking piece 32b. That is, when the locking projection 35 of the movable support portion 3 is locked to the lower end of the short vertical groove portion 26 and hangs vertically downward, the board 9 closes the opening on the shelf and the locking projection 35 of the movable support portion 3 When the board 9 is locked to the lower end of the long vertical groove portion 23 and vertically hangs down to the lower display shelf side, the board 9 opens an opening on the shelf, and the locking projection 35 of the movable support portion 3 is connected to the rear end of the short horizontal groove portion 24. The board 9 opens the opening on the shelf when it is locked on the side and lay down.

  Next, a method of using the column 10 will be described. As shown in FIG. 8, the opening on the shelf is usually closed by the board 9. In this case, a board 9 serving as a door is installed across the movable support portions 3 of the pair of columns 10. That is, the upper left and right ends of the board 9 are locked to the upper locking pieces 32a, and the lower left and right ends are locked to the lower locking pieces 32b. Thus, the movable support 3 and the board 9 are integrated. The fixed-side support 2 is attached to the front end of the top plate 22f of the multi-stage display shelf. That is, the lower locking portion 22 of the fixed-side support portion 2 is fixed to the front edge of the top plate 22f by locking. As a result, the fixed-side support portion 2 is fixed to the top plate 22f in an upright manner. As shown in FIG. 9, in this state, the locking projection 35 of the movable support 3 is locked to the bottom wall 241 which is the lower end of the short vertical groove 26, and the movable support 3 is By hanging down around the locking projection 35 and hitting the fixed column 2, the front part, which is a part of the fixed column 2, is covered. In this state, the replenishment product for stock placed on the shelf is hidden by the board 9 and cannot be seen.

  Next, a stock replenishment product placed on the shelf is taken out or replenished. At this time, the user holds the lower end of the board 9 or the movable support portion 3 and pivots upward to open an opening on the shelf. The movable support 3 rotates smoothly around the locking projection 35. Next, when the movable support portion 3 is in a substantially horizontal posture, the locking protrusion 35 is locked to the rear end of the short lateral groove portion 24 by pushing the movable support portion 3 to the rear side. At this time, since the back surface of the front side plate 31 of the movable support portion 3 hits the upper end of the small projection 27 of the fixed-side support 2 and supports the movable support portion 3, the movable support portion 3 does not fall forward and is substantially horizontal. You can maintain your posture. In this state, both hands of the worker are empty and can take out or replenish stock replenishment items placed on the shelf from the opening on the shelf. In addition, since the short lateral groove portion 24 is inclined slightly downward to the rear, the movable support portion 3 is pulled out slightly forward, and the locking projection 35 is positioned forward from the end of the short lateral groove portion 24. The distance between the upper end of the protrusion 27 and the back surface of the front side plate 31 of the movable support portion 3 increases, and the movable support portion 3 can be smoothly rotated without the direct contact of the movable support portion 3 and the small protrusion 27. .

  As a method for opening the opening on the shelf, other than the method for opening the opening on the shelf in FIGS. 10 to 12, a method as shown in FIGS. 13 and 14 can be adopted. That is, in FIGS. 13 and 14, the locking projection 35 of the movable support portion 3 that supports the board 9 is locked to the lower end (end) of the long vertical groove portion 23 of the fixed-side support portion 2, and Will hang down to the lower display shelf side, opening the front opening of the space on the shelf. As a result, on the shelf, the space up to the ceiling is opened, except for the pair of left and right fixed-side columns 2, 2, so that it is easier to take out and restock stock products. Further, since the operation can be performed only by the vertical operation without rotating the board 9, the operation can be safely performed on the stepladder. In addition, since the up-and-down operation can be performed at a low reach, the operation can be performed at a position where the stepladder is low, which is safe.

  As shown in FIG. 14B, the pair of locking projections 35 of the movable support portion 3 are loosely fitted to the pair of locking grooves 23A so as to be sandwiched from both sides. Therefore, the movement of the movable support 3 in FIGS. 8 to 14 can be easily performed by manually operating the board 9 or the movable support 3. For example, from the state in which the locking projection 35 in FIGS. 13 and 14 is locked to the lower end of the long vertical groove portion 23 (one end of the locking groove 23A), the locking projection 35 in FIGS. In order to move the board 9 or the movable support 3 upward, the board 9 or the movable support 3 is moved while being locked to the rear end of the horizontal groove 24 (the other end of the locking groove 23A). The locking projection 35 moves along the shape of the locking groove 23 </ b> A, so that the locking projection 35 enters the short vertical groove 26 from the connecting groove 25. Next, by slightly dropping the board 9 or the movable support portion 3, the locking projection 35 reaches the bottom wall portion 241 of the short vertical groove portion 26. Next, the locking projection 35 reaches the rear end (end) of the short lateral groove portion 24 by pushing the board 9 or the movable support portion 3 rearward while pushing it upward. Also, from the state where the locking projection 35 in FIGS. 10 to 12 is locked to the rear end of the short lateral groove 24 (the other end of the locking groove 23A), the locking projection 35 in FIGS. In order to move to a state where it is locked to the lower end of the long vertical groove portion 23 (one end of the locking groove 23A), an operation in the reverse procedure of the above operation method may be performed.

  Next, a support body according to a second embodiment of the present invention will be described with reference to FIGS. 15 to 18, the same components as those of the support members of FIGS. 1 to 14 are denoted by the same reference numerals, and the description thereof will be omitted, and different points will be mainly described. That is, the support 10a shown in FIGS. 15 to 18 differs from the support 10 shown in FIGS. 1 to 14 in the movable support. That is, the movable support portion 3a in FIGS. 15 to 18 has a height adjusting function corresponding to boards having different heights. That is, the movable support portion 3A has the support main body portion 3a and the height adjusting member 8 which can be inserted into the support main body portion 3a and is movable in the vertical direction by a predetermined dimension.

  The support body 3a has a shallow concave portion 31a surrounded by left and right side plates 364 and 364, a bottom plate 365 and a lower plate 366, in which an upper portion of the front side plate 31 is cut out. At the front end of the left and right plates 364, six small protrusions 361 extending inward at an appropriate pitch in the vertical direction are formed, and a guide rail 362 on the back side of the small protrusion 361 is formed. Reference numeral 363 is a hole for forming a mold. In the center of the bottom plate 365 in the left-right direction, a large number (ten in this example) of locking holes 367 are formed at an appropriate pitch in the up-down direction.

In the present example, the height adjusting member 8 is shorter than the height of the concave portion 31a, and fits slidably in the vertical direction on the concave portion 31a of the support body 3a. The height adjusting member 8 has flanges 83a, 83a, which extend in the longitudinal direction and are engaged with the guide rails 362 of the support main body 3a, at both rear end edges of the short plate-like body, and a board 9 is provided at an upper end. Is formed, and a thin flexible locking piece 82 is formed below the upper locking piece 32a. On the back surface of the flexible locking piece 82, a small projection 821 is formed to be locked in a locking hole 367 formed in the concave portion 31a of the support main body 3a. The height adjusting member 8 is slidably fitted in the concave portion 31a of the support main body 3a, and is fixed by locking the small projection 821 and the locking hole 367. Further, the height adjusting member 8, for example, by raising L _2, the height of the board 9 (vertical length) can be correspond to those of large, the height adjustment member 8, for example, to lower L _1, board 9 can correspond to a small one (see FIG. 17).

  Next, a support according to a third embodiment of the present invention will be described with reference to FIGS. 19 and 20, the same components as those of the support members of FIGS. 1 to 14 are denoted by the same reference numerals, and the description thereof will be omitted. Differences will mainly be described. That is, the support 10b of FIGS. 19 and 20 is different from the support 10 of FIGS. 1 to 14 in that the shape of the locking groove of the fixed support and the movable support 3 is in a horizontal state above. This is a holding mechanism for the support unit 3. That is, in the locking groove 23B of the support body 10b in FIGS. 19 and 20, the difference from the locking groove 23A in FIGS. 1 to 14 is that the short lateral groove 24 of the locking groove 23A is omitted. . That is, the locking groove 23 </ b> B of the fixed column 2 is vertically elongated, the connecting groove 25 is continuous with the upper end of the long vertical groove 23, and extends slightly rearward, and is connected to the rear end of the connecting groove 25. The locking projection 35 reciprocates from the lower end of the long vertical groove 23 to the lower end wall 241 of the short vertical groove 26 via the connecting groove 25. It is free.

  Further, as a holding mechanism for holding the open state (horizontal state) of the movable support portion 3 in the support body 10b, the support member 10b protrudes inward on the inner side surfaces (back surfaces) of the left and right side plates 34a and 34b on the upper side of the movable support portion 3. The point is that the holding projection 39 is provided. That is, the formation position of the holding projection 39 is behind the locking projection 35, and is located below the bottom wall 241 of the short vertical groove portion 26 when the movable support portion 3 is in the open state (horizontal state). This is a position where it comes into contact with the inner side surface of the rear wall 212 forming the concave groove 241 of the rib structure of the side support portion 2. The height of the holding projection 39 may be any height as long as the horizontal state in FIG. 20 is maintained. In other words, when the movable support 3 is moved from the state shown in FIG. 19 to the horizontal state shown in FIG. 20, the holding projection 39 abuts on the rear wall 212 of the fixed column 2, but the upper left and right side plates 34 a and 34 b are bent to both sides. As a result, the fixed side support portion 2 is moved over and locked on the inner surface of the rear wall 212. As described above, the same effects as those of the support 10 can be obtained in the support 10b.

  The support body of the present invention is not limited to the above embodiment, but can take various modifications. The locking grooves 23A and 23B may not be groove structures but may be locking holes that penetrate left and right. Further, the locking grooves 23A and 23B may be a mixture of a groove through which a part of the groove bottom penetrates and a through hole. Also in the locking groove having such a locking hole or a partial through hole, the same operation and effect as those of the locking grooves 23A and 23B can be obtained. Further, for example, the connecting groove 25 is not limited to the round shape shown in FIG. 5, and may be a round having various curvatures, or may be an irregular groove other than the round. In addition, the short lateral groove portion 24 is not limited to the downward descending inclination, and may be a lateral groove having no inclination. Further, the small protrusion 27 at the upper end of the fixed-side support 2 may not be provided. Further, the lower locking portion 22 of the fixed-side column portion 2 may be a fixing method using a fixing auxiliary tool such as a screw. The rib structure 21 located behind the long vertical groove portion 223 of the fixed-side support portion 2 may not be provided, and may be a flat surface. The left and right side plates 33a and 33b of the movable support 3 can be omitted. Also, the upper left and right side plates 34a and 34b are not limited to the large side plate shape as shown in FIG.

  According to the present invention, the pair of projections of the movable support portion on the board side are loosely fitted so as to sandwich a pair of locking grooves or locking holes formed on both surfaces of the fixed-side support portion on the fixed side, Since the locking is performed, when opening and closing the board, the operation is stable and the work can be performed easily.
