[0005] [Patent Document 1] Japanese Patent Publication No. 2022-109295 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the above-mentioned sliding shelf locking structure, the operator must extend his or her fingers from the underside of the sliding shelf main body and move them toward the back of the sliding shelf main body, which creates the problem of reduced operability depending on the position of the sliding shelf main body in the vertical direction, especially when it is located at the bottom.

[0007] In view of the above circumstances, the present invention provides a locking structure for a sliding shelf that can prevent a decrease in operability at any position in the vertical direction. [Means for solving the problem]

[0008] In the invention of claim 1, there is provided a locking structure for a sliding shelf including a support part and a slide part that is movable along a front-rear direction relative to the support part via a slide rail, The support portion includes a pair of shelf brackets and a connecting member that spans the pair of shelf brackets at their tip ends, the slide portion comprises a display shelf member and an operating member that is rotatable about an axis in the left-right direction relative to the display shelf member and is disposed on the back side of the display shelf member across substantially the entire width in the left-right direction; The connecting member has a recessed or protruding engaging portion that can be engaged with the operating member, the operating member includes a pair of left and right side walls, an upper wall connected to upper ends of the side walls, and a front wall connected to a front end of the upper wall, The upper wall has left and right end portions each having a recessed or protruding portion corresponding to the engaging portion, the recessed or protruding portion extending downward and capable of engaging with the engaging portion; an operating unit that is operated by an operator is disposed on the front wall; the display shelf member includes an upper wall, a front wall connected to a front end of the upper wall, and attachment portions that constitute side wall portions at left and right ends of the upper wall, When the locked portion and the locking portion are locked, the sliding portion is locked. By rotating the operating portion toward the front wall of the display shelf member, the locked state between the locked portion and the locking portion is released, and the sliding portion is unlocked.

[0009] This allows the operator to release the locked state between the locked portion and the locking portion by bending the finger toward the operator, thereby preventing a decrease in the operability of the sliding shelf.

[0010] The operation unit can be operated by a finger other than the thumb of the operator, The front wall of the display shelf member serves as a contact portion that can come into contact with the operator's thumb.

[0011] This allows the operator to bend the fingers other than the thumb toward the thumb and grip the slide shelf, which helps prevent a decrease in operability of the slide shelf.

[0012] The operating portion is disposed above the rotation axis of the operating member, The engaging portion between the engaged portion and the engaging portion is disposed above and behind the rotation axis of the operating member.

[0013] This allows the locking structure of the sliding shelf to be arranged on the back side of the display shelf component, making it difficult to see from the outside, thereby improving the design.

[0014] The operating member has a free end that can rotate downward under its own weight. a stopper that restricts the operation member from rotating downward is disposed on the mounting portion of the display shelf member; The side wall of the operating member is provided with an abutment portion that abuts against the stopper to restrict downward rotation of the operating member.

[0015] This prevents the operating member from rotating too far downward and becoming inoperable.

[0016] The locking portion is formed in a convex shape, and the locked portion is formed in a concave shape, The locking portion is provided with a guide portion that guides the locking portion to the locked portion.

[0017] According to this, when the sliding portion is pulled out and then returned to its original position, the guide portion can easily engage the locked portion with the locking portion, thereby improving operability. [Brief explanation of the drawings]

[0022] The main body frame 20 includes a base frame 30, a support column 40, and a rear panel 50.

[0023] The base frames 30 are made of metal and have a rectangular pillar-like external shape, and are arranged at the left and right ends of the product display shelf 10 with their longitudinal directions aligned with the front-to-rear direction. Adjusters 31 are attached to the underside of the base frames 30 to adjust the installation height relative to the installation surface. Support columns 40 are erected from the rear ends of each base frame 30.

[0024] The support pillars 40 are made of metal, formed in a rectangular cylindrical shape, and connected at the rear end of each base frame 30. A plurality of locking holes 41 are arranged in the front wall of the support pillars 40 along the vertical and left-right directions, penetrating from the outer surface to the inner surface and formed as rectangular through-holes that are long in the vertical direction.

[0025] The rear panel 50 is made of synthetic resin and is formed in the shape of a rectangular flat plate, and is attached so as to span between the left and right support columns 40.

[0026] As shown in FIGS. 3 to 9, the sliding shelf 60 includes a support portion 61 and a sliding portion 62. As shown in FIGS.

[0027] The support portion 61 includes a pair of shelf board brackets 70 and a connecting member 74 that spans the pair of shelf board brackets 70 at their tip ends.

[0028] The shelf bracket 70 is made of metal and is formed into an elongated shape that is long in the front-to-rear direction. An inverted L-shaped locking hook 71 is disposed at the rear end of the shelf bracket 70.

[0029] As shown in FIGS. 1 and 2, the shelf bracket 70 is attached to the support 40 by inserting and locking the locking hooks 71 into the locking holes 41.

[0030] When the shelf bracket 70 is attached to the support 40, a protruding portion 72 is provided at the tip (front side) thereof, which protrudes inward and to which a connecting member 74 can be attached.

[0031] A fixing portion 101 of a slide rail 100 is attached to the inside of the shelf board bracket 70. The slide rail 100 is an existing one.

[0032] The connecting member 74 is made of metal and has a roughly U-shaped cross section that is open at the bottom, and the left and right ends are attached to the protruding portion 72 by bolts so as not to interfere with the movement of the sliding portion 62.

[0033] The connecting member 74 is provided with a locked portion 75 that can be locked with the operating member 90. In this embodiment, the locked portion 75 is configured by the periphery of a rectangular through-hole that penetrates the upper wall 74a of the connecting member 74 in the up-down direction, and the upper wall 74a in front of the through-hole.

[0034] The slide portion 62 includes a display shelf member 80 and an operating member 90 that is rotatable about an axis in the left-right direction relative to the display shelf member 80 and is arranged on the back surface 80a side of the display shelf member 80 across substantially the entire width in the left-right direction.

[0035] The display shelf member 80 is made of metal and comprises an upper wall 81, a front wall 82 that is connected to the front end of the upper wall 81 and extends downward, mounting portions 83 that extend downward at the left and right ends of the upper wall 81 and form side wall portions, and a rear wall 84 that is connected to the rear end of the upper wall 81 and extends upward, and is formed in the shape of a rectangular flat plate that is long in the left-right direction.

[0036] The front side of the front wall 82 is a contact portion 82a that can come into contact with the operator's thumb.

[0037] A stopper 85 is provided on the mounting portion 83 of the display shelf member 80 to restrict the operation member 90 from rotating downward.

[0038] The operating member 90 includes a pair of left and right side walls 91 , an upper wall 92 connected to the upper ends of the side walls 91 , and a front wall 93 connected to the front end of the upper wall 92 .

[0039] At the left and right ends of the upper wall 92, engaging portions 94 that include portions formed in a convex shape corresponding to the engaged portions 75 and can be engaged with the engaged portions 75 are provided extending downward.

[0040] In this embodiment, the locking portion 94 has a triangular portion 94a formed in a triangular plate shape, a square portion 94b formed in a rectangular flat plate shape, and a trapezoidal portion 94c formed in a trapezoidal plate shape connecting the triangular portion 94a and the square portion 94b. The front surface of the triangular portion 94a comes into contact with the front periphery of the through hole constituting the locked portion 75, and the lower surface of the large diameter portion comes into contact with the front upper wall 74a of the through hole constituting the locked portion 75, thereby locking the locked portion 75 and the locking portion 94. The hypotenuse of the triangular portion 94a serves as a guide portion 94d that guides the locking portion 94 to the locked portion 75.

[0041] An operating section 93a that is operated by an operator is provided on the front wall 93. In this embodiment, the rear surface side of the front wall 93 serves as the operating section 93a.

[0042] The operation unit 93a can be operated by the operator's fingers other than the thumb.

[0043] The operating member 90 is attached to the side wall 91 using a shaft member 95, a resin washer 96, a nut 97, etc. so as to be rotatable about an axis extending in the left-right direction and the front end of the attachment portion 83. In this embodiment, the free end side of the operating member 90 is rotatable downward by its own weight.

[0044] The side walls 91 of the operating member 90 are provided with contact portions 91a that come into contact with the stoppers 85 to restrict the operating member 90 from rotating downward.

[0045] When the operation member 90 rotates due to its own weight and the stopper 85 releases the lock, the guide portion 94d is positioned so as to come into contact with the corner portion of the upper front side of the connecting member 74 when the operator releases the lock.

[0046] To explain in detail how the slide portion 62 is attached, as shown in FIGS. 3 to 9, the slide rail 100 is attached to the shelf board bracket 70 at the fixing portion 101.

[0047] The movable part 102, which is the tip of the slide rail 100 when extended, is connected to the mounting part 83 of the display shelf component 80, and the extension and contraction of the slide rail 100 allows the slide part 62 to move in the front-to-rear direction.

[0048] With the above configuration, the operating portion 93a is arranged above the rotation axis S of the operating member 90, and the engaging portion between the engaged portion 75 and the engaging portion 94 is arranged above and rearward of the rotation axis S of the operating member 90.

[0049] With this configuration, the locking structure 200 of the sliding shelf 60 can be arranged on the rear surface 80a side of the display shelf member 80, and the locking structure 200 is less visible from the outside, improving the design.

[0050] 8, when the locked portion 75 and the locking portion 94 are locked, the sliding portion 62 is locked and the sliding portion 62 is restricted from moving forward relative to the support portion 61. In other words, the sliding portion 62 cannot be pulled out.

[0051] As shown in Figure 9, by rotating the operating part 93a toward the front wall 82 of the display shelf member 80, the locked state between the locked part 75 and the locking part 94 is released, the sliding part 62 is unlocked, and the sliding part 62 becomes movable in the front-to-back direction relative to the support part 61.

[0052] The locking structure 200 of this embodiment has as its components a connecting member 74, a display shelf member 80, an operating member 90, a locking portion 75 of the connecting member 74, a locking portion 94 of the operating member 90, a guide portion 94d, a contact portion 82a of the display shelf member 80, an attachment portion 83, a stopper 85, etc.

[0053] The following describes the usage and function of the locking structure 200 in this embodiment. In the state shown in Figures 1, 3, and 8, the sliding portion 62 is not pulled out, and the locked portion 75 and the locking portion 94 are locked together.

[0054] When the operator wishes to pull out the slide portion 62 to the front, he or she inserts his or her hand from the back surface 80a (bottom side) of the display shelf member 80, touches the operating portion 93a with fingers other than the thumb, and then touches the contact portion 82a with the operator's thumb.

[0055] Then, the operator bends the fingers other than the thumb toward the thumb and operates to grasp the operating portion 93a.

[0056] The locking portion 94 rotates upward and disengages from the locked portion 75, and as shown in FIG. 9, the locked portion 75 and the locking portion 94 are released from the locked portion 75.

[0057] In this state, by pulling the slide portion 62 forward (toward the operator), the slide portion 62 can be pulled out relative to the support portion 61 as shown in FIGS.

[0058] Even if the operator releases the operating member 90, the stopper 85 comes into contact with the contact portion 91a, preventing the operating member 90 from rotating too far downward and becoming inoperable. In other words, the operating member 90 is restricted from rotating downward.

[0059] When the slide part 62 is pulled out and then returned to its original position, the operating member 90 is lifted upward by the guide part 94d, so that the locked part 75 and the locking part 94 can be easily locked together without visual inspection.

[0060] The locking structure 200 of the sliding shelf 60 of this embodiment is a locking structure of the sliding shelf 60 including a support portion 61 and a slide portion 62 that is movable in the front-rear direction relative to the support portion 61 via a slide rail 100, The support portion 61 includes a pair of shelf board brackets 70 and a connecting member 74 that spans the leading ends of the pair of shelf board brackets 70. The slide section 62 includes a display shelf member 80 and an operating member 90 that is rotatable about an axis in the left-right direction relative to the display shelf member 80 and is disposed on the back surface 80a side of the display shelf member 80 across substantially the entire width in the left-right direction; The connecting member 74 is provided with a recessed or projecting locked portion 75 that can be locked with the operating member 90. The operating member 90 includes a pair of left and right side walls 91, an upper wall 92 connected to the upper ends of the side walls 91, and a front wall 93 connected to the front end of the upper wall 92. The upper wall 92 has left and right end portions each having a recessed or protruding portion corresponding to the corresponding one of the engaging portions 75, and each of the engaging portions 94 extends downward. An operating section 93a that is operated by an operator is provided on the front wall 93. The display shelf member 80 includes an upper wall 81, a front wall 82 connected to the front end of the upper wall 81, and mounting portions 83 that form side wall portions at the left and right ends of the upper wall 81. When the locked portion 75 and the locking portion 94 are locked, the sliding portion 62 is locked. By rotating the operating portion 93a toward the front wall 82 of the display shelf member 80, the locked state between the locked portion 75 and the locking portion 94 is released, and the sliding portion 62 is unlocked.

[0061] This allows the operator to release the locked state between the locked portion 75 and the locking portion 94 by bending the finger toward the operator, thereby preventing a decrease in the operability of the sliding shelf 60.

[0062] In addition, the operation unit 93a can be operated by the operator's fingers other than the thumb, The front wall 82 of the display shelf member 80 is configured as a contact portion 82a that can come into contact with the thumb of an operator.

[0063] This allows the operator to bend the fingers other than the thumb toward the thumb and grip the sliding shelf 60, which helps prevent a decrease in operability of the sliding shelf 60.

[0064] In addition, the operating portion 93a is disposed above the rotation axis S of the operating member 90, The engaging portion between the locked portion 75 and the engaging portion 94 is disposed above and behind the rotation axis S of the operating member 90.

[0065] This allows the locking structure 200 of the sliding shelf 60 to be arranged on the rear surface 80a side of the display shelf member 80, making it difficult to see from the outside, thereby improving the design.

[0066] The free end of the operating member 90 is rotatable downward by its own weight. A stopper 85 is provided on the mounting portion 83 of the display shelf member 80 to restrict the operation member 90 from rotating downward. A contact portion 91a is provided on the side wall 91 of the operating member 90 to contact the stopper 85 and restrict the operating member 90 from rotating downward.

[0067] This prevents the operating member 90 from rotating too far downward and becoming inoperable.

[0068] In addition, the locking portion 94 is formed in a convex shape, and the locked portion 75 is formed in a concave shape, The locking portion 94 is provided with a guide portion 94d that guides the locking portion 94 to the locked portion 75.

[0069] This allows the guide portion 94d to easily engage the locked portion 75 with the locking portion 94 when the slide portion 62 is pulled out and then returned to its original position, thereby improving operability.

[0070] The locking structure for the sliding shelf of the present invention is not limited to the above-described configuration. In other words, various design modifications are possible without departing from the gist of the present invention. Examples of modified embodiments are shown below.

[0071] For example, while the locked portion 75 is concave and the locking portion 94 is convex, it is also possible to make the locked portion 75 convex and the locking portion 94 concave, and the shapes and arrangements of each can also be changed as appropriate depending on the usage.
