FIG. 2 is a partial perspective view of the shelf support according to the present invention when viewed from the rear of the product display shelf. Further, FIG. 3 is a cross-sectional view of a main part showing the structure of the shelf support of the present invention. The illustrated shelf support column 10 regulates the sliding of the tubular main body portion 11, the tubular extension portion 12 slidably fitted into the main body portion 11, and the main body portion 11 and the extension portion 12. The fixing member 13 and the fixing member 13 are provided. In the shelf support column 10, the fitting length of the extension portion 12 with respect to the main body portion 11 is fixed by restricting the sliding between the main body portion 11 and the extension portion 12 by the fixing member 13, and the total length of the pillar can be set. It is said that. Further, on the front surface of the main body portion 11 and the extension portion 12, a plurality of locking holes 11a and 12a for receiving the locking claw 107a of the shelf board support 107 and dropping the locking claw 107a downward to lock the shelf plate support 107a are provided in height. It is provided at equal pitches in the direction. These locking holes 11a and 12a are formed in a vertically long substantially rectangular shape. On the other hand, on the back surface of the extension portion 12, a plurality of second through holes 12b are formed at a position where the position in the height direction coincides with the locking hole 12a at the same pitch as the locking hole 12a.

Further, as shown in the figure, in the shelf support column 10 according to the present invention, above the main body portion 11, a short tubular shape having a cross-sectional shape substantially the same as the cross-sectional shape in the direction orthogonal to the longitudinal direction of the main body portion 11 The member 14 is arranged so as to be in contact with the fitting opening of the main body portion 11. The main body 11, the extension 12, and the tubular member 14 are all square tubular, and the extension 12 is slidably fitted to the main body 11 and the tubular member 14 on three side surfaces.

In the present invention, the fixing member 13 that regulates the sliding between the main body portion 11 and the extension portion 12 and sets the total length of the column slides inside the tubular member 14 and the main body portion 11 with respect to the extension portion 12. The feature is that it is stored freely. Conventionally, the fixing means that protrudes from the main body of the support to the back side is stored inside the tubular member 14 and the main body 11 that make up the support, so that the display shelf can be used in a store or the like. It is possible to solve problems such as a dead space being generated between the wall and the like when arranging, and the wall and the like being damaged by the protruding portion. On the other hand, since the function of setting the total length of the column is secured by restricting the sliding between the main body portion 11 and the extension portion 12 by the fixing member 13, the degree of freedom of the shelf adjustment function is not impaired. As will be described later, the tubular member 14 is provided so that the shelf plate support 107 can be attached to the stepped portion with the extension portion 12 at the upper end of the main body portion 11, and is therefore essential in the present invention. Instead, when the tubular member 14 is not provided, the fixing member 13 is housed inside the main body 11.

In the present embodiment, the fixing member 13 has a member main body 131 slidably arranged with respect to the extension portion 12 adjacent to the extension portion 12, and a lock claw swingably supported with respect to the member main body 131. It has 132 and. In the illustrated example, the lock claw 132 of the fixing member 13 is housed in the tubular member 14 arranged in contact with the fitting opening of the main body portion 11.

FIG. 4 shows a perspective view showing the member main body 131 of the fixing member 13 taken out. As shown in the figure, the member main body 131 has a flat plate-shaped sliding surface 131A that slides with respect to the extension portion 12, and projects from both sides of the sliding surface 131A to the back side in a direction substantially perpendicular to the sliding surface 131A. It has a substantially U-shaped cross-sectional shape, including a flat plate-shaped side surface portion 131B. The sliding surface 131A is provided with a first through hole 131a, and the tip portion 132a of the lock claw 132 enters the extension portion 12 side through the first through hole 131a. Further, the side surface portion 131B is provided with a fixing portion 131C for axially supporting the lock claw 132. The fixing portion 131C can be fixed to the side surface portion 131B by means such as welding.

FIG. 5 is a perspective view showing the lock claw 132 of the fixing member taken out. The lock claw 132 penetrates the hole 131b provided in the side surface portion 131B and the fixing portion 131C and the hole 132c provided in the base end portion 132b of the lock claw 132 in a state of being arranged between the fixing portions 131C. The horizontal shaft 133, such as a screw fixed to the side surface portion 131B and the fixing portion 131C, swingably supports the member main body 131. Further, from the viewpoint of improving workability, a protrusion 132d is provided on the base end portion 132b side of the lock claw 132 to put a finger on the lock claw 132 when the lock claw 132 is rotated to release the lock.

The lock claw 132 supported by the horizontal shaft 133 at the base end portion 132b has a center of gravity on the tip end portion 132a side. As a result, a moment is generated to tilt the tip portion 132a toward the back surface side of the extension portion 12, and the tip portion 132a of the lock claw 132 passes through the first through hole 131a of the sliding surface 131A of the fixing member 131 to extend the extension portion 12. It becomes possible to enter the side. Therefore, the back surface of the extension portion 12 and the sliding surface 131A of the fixing member 131 slide, and the position of the second through hole 12b on the back surface of the extension portion 12 and the first of the sliding surface 131A of the fixing member 131. If the position of the through hole 131a moves relative to the height direction and the position of the second through hole 12b and the first through hole 131a in the height direction match, the tip portion 132a of the lock claw 132 due to its own weight. It falls into the second through hole 12b through the first through hole 131a and enters the second through hole 12b. As a result, the descent of the extension portion 12 is restricted. Therefore, by adopting such a fixing member configuration, the extension portion can be easily and quickly fixed with an arbitrary pull-out length, so that the workability of assembling and disassembling can be improved.

Therefore, when the extension portion 12 is moved upward by applying an external force and pulled out from the main body portion 11, the tip portion 132a of the lock claw 132 sequentially enters the second through hole 12b of the extension portion 12. Therefore, when the external force acting on the extension portion 12 is removed, the extension portion 12 tries to descend due to its own weight, but the descent is blocked by the lock claw 132 that has entered the second through hole 12b.

On the other hand, a fixing hole 131c is provided near the upper end of the sliding surface 131A of the member main body 131. As shown in FIG. 3, in a state where the tip portion 132a of the lock claw 132 has entered the second through hole 12b, extraction is suppressed into the second through hole 12b of the extension portion 12 through the fixing hole 131c. By allowing the member 134 to enter, the extension portion 12 is restricted from rising. As a result, in addition to the lowering of the extension portion 12, the ascending portion is also regulated, so that the extension portion 12 can be stably fixed to the main body portion 11 at a target height.

Further, the member main body 131 is preferably formed in a long shape in the height direction. The member main body 131 has a substantially U-shaped cross-sectional shape, and slides on the main body portion 11 and the extension portion 12 on the three side surfaces of the sliding surface 131A and the pair of side surface portions 131B and the end faces of the side surface portions 131B. Since it is freely fitted, it is possible to prevent the extension portion 12 from rattling in the main body portion 11 by assuming that the member main body 131 is formed in a long shape. The length of the member main body 131 in the height direction may be such that the extension portion 12 is stably fixed in the main body portion 11, and is preferably 150 mm or more, preferably 500 mm or less. it can.

In the present invention, the fixing member 13 may be provided with an urging means for urging the lock claw 132 in the direction of entering the second through hole 12b over the lock claw 132 and the member main body 131. For example, the urging means may be a vine-wound spring that is extrapolated to the horizontal shaft 133 and has one end supported by the lock claw 132 and the other end supported by the member main body 131. As a result, in addition to its own weight, the lock claw 132 can be forcibly entered into and abutted against the second through hole 12b by the urging means, thereby eliminating the improper entry of the lock claw 132, that is, the lock defect. It is possible to enable a quick and highly reliable locking operation. In addition, a clicking sound is generated when the lock claw 132 enters, so that a comfortable operation feeling can be obtained.

As shown in FIG. 3, the tubular member 14 has an auxiliary locking hole having the same shape as the locking hole 11a of the main body portion 11 on the sliding surface side with the extension portion 12, that is, the front side of the shelf support column 10. At least one of 14a is provided. By providing such a tubular member 14, the shelf board support 107 can be attached so as to straddle the stepped portion with the extension portion 12 at the upper end of the main body portion 11, and the shelf can be avoided from the position of the stepped portion. Since it is not necessary to install the plate 104, the shelf plate can be arranged at any position over the entire length of the support column, and the degree of freedom as a shelf adjustment function is improved.

Further, the tubular member 14 has a notch 14d that opens to the lower end side of the tubular member 14 on the arrangement side of the fixing member 13, that is, on the back surface side of the shelf support. In the illustrated example, the convex portion 131D is formed on the back surface side of the pair of fixing portions 131C fixed to the pair of side surface portions 131B of the member main body 131 housed in the tubular member 14. The convex portion 131D of the above projects from the notch 14d to the outside of the tubular member 14. Since the notch 14d is open to the lower end side of the tubular member 14, when the tubular member 14 is placed in contact with the fitting opening of the main body 11, the upper end of the main body 11 is the notch 14d. Form the lower edge. Therefore, the position of the fixing member 13 is defined by engaging the pair of convex portions 131D with the upper end portion of the main body portion 11. The member main body 131 can be further fixed to the main body portion 11 by welding, screws, or the like.

In the present invention, the fixing member 13 is preferably arranged near the upper end of the main body portion 11 as shown in the figure. As a result, the length of the extension portion 12 that can be pulled out can be increased as compared with the case where the fixing member 13 is provided in the middle portion of the main body portion 11 in the height direction. That is, the extension portion 12 can be fixed in a state of being pulled out as much as possible upward from the main body portion 11.

Here, as shown in FIG. 3, the tip portion 132a of the lock claw 132 enters the second through hole 12b to restrict the lowering of the extension portion 12, and the sliding between the main body portion 11 and the extension portion 12 In the state where the movement is restricted, the positions of the locking hole 11a of the main body 11 and the upper edge of the locking hole 12a of the extension 12 in the height direction are the same. That is, in the present invention, the main body 11 and the extension 12 are the locking holes 11a and the extension 12 of the main body 11 arranged at equal pitches in a state where the lowering of the extension 12 is restricted at any position. The locking holes 12a are formed so as to overlap each other and be connected to each other. When the locking holes 11a and 12a are connected in this way, the locking claws 107a of the shelf board support 107 can be locked by the locking holes 11a and 12a. In the present embodiment, as shown in FIG. 3, at the upper end of the main body 11 and the upper end and the lower end of the tubular member 14 on the front side, there are notches that match the forming pitch with the locking holes 11a of the main body 11. Parts 11b and 14b, 14c are formed.

As shown in the figure, the locking hole 12a of the extension portion 12 can be formed longer than the locking hole 11a of the main body portion 11 by at least the amount of the locking claw 107a dropped. In the illustrated shelf support 10, the locking claw 107a is inserted into the locking holes 11a and 12a of the main body 11 or the extension 12, and the drop groove 107b fits into the lower edge of the locking hole 11a or 12a. By inserting it, it is dropped downward and locked, but at the portion where the extension portion 12 is fitted in the main body portion 11, the lower edges of the locking holes 11a and 12a of the main body portion 11 and the extension portion 12 are inserted. If they are at the same height, the thickness of the lower edge of the hole is substantially increased, so that the drop groove 107b cannot be fitted. Therefore, by forming the lower edge of the locking hole 12a of the extension portion 12 at a position lower than the lower edge of the locking hole 11a of the main body portion 11 by at least the amount of the locking claw 107a dropped. Even in the portion where the extension portion 12 is fitted in the main body portion 11, the drop groove 107b is fitted into the lower edge of the locking hole 11a, so that the locking claw 107a is lowered in the same manner as the other portions. It will be dropped into and locked, and the locked state of the shelf board support will be assured.

In the structure of the shelf support column 10 of the present invention, first, a fixing member 13 including a member main body 131 in which a lock claw 132 is fixed to an upper end portion is fitted inside the main body portion 11. At this time, the tip 132a of the lock claw 132 is housed in the member body 131 even if it protrudes forward from the first through hole 131a provided on the sliding surface 131A of the member body 131. It may be in the state of being done. After that, the tubular member 14 is abutted and arranged in the fitting opening of the main body 11. At this time, by engaging the convex portion 131D formed on the end surface of the side surface portion 131B of the member main body 131 with the notch portion 14d formed on the back surface side of the tubular member 14, the vertical position of the fixing member 13 is positioned. Can be specified.

After that, the extension portion 12 is fitted from above into the space formed by the inner peripheral surface of the main body portion 11 and the sliding surface 131A of the member main body 131. At this time, if the tip portion 132a of the lock claw 132 remains protruding from the first through hole 131a to the front side, the fitting of the extension portion 12 is hindered. Therefore, when the extension portion 12 is fitted, the tubular member 14 is inserted. Is moved upward so that the tip portion 132a of the lock claw 132 is positioned in the member main body 131. For example, the tip 132a of the lock claw 132 is housed in the member main body 131 by manually pushing the protrusion 132d downward to rotate the lock claw 132. When the extension portion 12 once fitted is pulled up to adjust the height of the shelf, the tip portion 132a of the lock claw 132 may remain protruding from the first through hole 131a toward the front side. After that, at a position corresponding to the target height, the tip portion 132a of the lock claw 132 of the fixing member 13 is provided through the first through hole 131a and the second through hole provided on the back surface side of the extension portion 12. By falling into 12b and entering, the descent of the extension portion 12 is restricted, and the height of the shelf support is fixed. Further, by allowing the extraction restraining member 134 to enter the second through hole 12b of the extension portion 12 through the fixing hole 131c of the member main body 131, the rise of the extension portion 12 is also regulated. As a result, the extension portion 12 can be stably fixed to the main body portion 11 at a desired height.
