[First Embodiment]
Hereinafter, the shelf board support according to the first embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the shelf board support 1 according to the present embodiment is attached to each of the plurality of columns Ra of the fixture R, and the shelf board (not shown) such as a pallet is lowered. A fixing portion 2 that is detachably fixed to the support column Ra, a support member 3 for supporting the shelf board, and a cam mechanism 6 that connects the fixing portion 2 and the support member 3 are supported from the above. Be prepared.

With reference to FIGS. 4 and 5, the fixing portion 2 includes a holder 4 having a substantially U-shaped cross section and a pair of sliding portions 5 slidably held in the front-rear direction D1 with respect to the holder 4. The fixing portion 2 is fixed to the support column Ra by sandwiching the support column Ra between the holder 4 and the slide portion 5. The holder 4 has a pair of guide portions 41 facing each other in the left-right direction D2, and a connecting portion 42 for connecting the rear end portions of the guide portions 41 to each other. In the example shown in FIG. 4, the support column Ra has a rectangular cross section, and the connecting portion 42 has an inner surface 42a that tapers forward in correspondence with the corner portion of the support column Ra.

Each guide portion 41 is composed of a C-shaped guide rail, and has a flat plate portion 41a and a pair of guide flanges 41b extending inward from both edges of the flat plate portion 41a in the vertical direction D3. As shown in FIG. 6, the flat plate portion 41a is provided with a vertically long guide hole H1.

Each slide portion 5 is held between a pair of upper and lower guide flanges 41b of the guide portion 41 and is slidable in the front-rear direction D1 with respect to the holder 4. Further, the rear end surface 5a of each slide portion 5 is inclined rearward in the left-right direction D2 so as to be able to come into surface contact with the support column Ra.

The support member 3 is formed in a rod shape extending in the front-rear direction D1, and a support portion 9 is provided at a front portion of the upper surface 3a thereof. The upper surface 9a of the support portion 9 has a curved surface that is convex upward, and more specifically, an arched surface that extends in an arch shape in a side view.

With reference to FIGS. 4 and 7, the cam mechanism 6 has a rotating portion 61, a pair of eccentric collars 62, and a pair of mounting pins 63. The rotating portion 61 is fixed to a rear portion of the support member 3, and both ends of the left-right direction D2 are rotatably housed and held in insertion holes H2 provided in each slide portion 5. With this configuration, the support member 3 and the rotating portion 61 are centered on the rotating shaft C1 (that is, the rotating portion 61 extending in the left-right direction D2) between the lower position (horizontal position) shown by the solid line and the upper position shown by the broken line in FIG. It is possible to turn around the line). Further, the rear end 3b of the support member 3 has an R shape, and prevents the rear end 3b of the support member 3 from interfering with the support column Ra when the support member 3 turns around the swivel shaft C1.

The pair of eccentric collars 62 are rotatably inserted and held on both the left and right sides of the rotating portion 61, and the rotation axis C2 (the center line of the eccentric collar 62 extending in the left-right direction D2) is eccentric with respect to the turning axis C1. Further, as shown in FIGS. 4 and 6, the lateral end of each eccentric collar 62 in the left-right direction D2 is inserted and held in the guide hole H1 of the guide portion 41. The guide hole H1 is a long hole long in the vertical direction D3, and the eccentric collar 62 held in the guide hole H1 is allowed to move in the longitudinal direction of the guide groove H1, that is, in the vertical direction D3, but moves to the front-rear direction D1. Is prevented from moving. Each mounting pin 63 is inserted into the corresponding eccentric collar 62 from the outside of the holder 2 to hold the eccentric collar 62 and the rotating portion 61.

Therefore, when the user turns the support member 3 from the lower position shown by the solid line to the upper position shown by the dotted line in FIG. 2, the rotating portion 61 rotates about the turning shaft C1 and the rotating shaft C2 (eccentricity) with respect to the turning shaft C1. The phase of the collar 62) is displaced. Along with this, the eccentric collar 62 moves upward with respect to the slide portion 5 by displacing the inside of the guide hole H1 upward, and the holder 4 is pushed by the rotating portion 61 and moves rearward with respect to the slide portion 5. .. In other words, the slide portion 5 moves relatively forward with respect to the holder 4 due to the eccentric amount of the eccentric collar 62. As a result, the holder 4 is released from the fixed position where the support column Ra is sandwiched between the inner surface 42a and the slide portion 5 as shown in FIG. 4 (a) to the support column Ra as shown in FIG. 4 (b). It moves to the non-fixed position, and the fixing of the shelf board support 1 to the support column Ra is released.

On the other hand, when the user turns the support member 3 from the upper position shown by the dotted line in FIG. 2 to the lower position (horizontal position) shown by the solid line, the eccentric collar 62 is displaced downward in the guide hole H1 according to the amount of eccentricity. , The holder 4 moves forward relative to the slide portion 5. As a result, the holder 4 moves from the non-fixed position shown in FIG. 4B to the fixed position shown in FIG. 4A, and the support column Ra is sandwiched between the rear end surface 5a of the slide portion 5 and the inner surface 42a of the holder 4. , The shelf board support 1 is fixed to the support column Ra.

Therefore, when adjusting the height of the shelf board support 1 with respect to the support column Ra, the support member 3 is swiveled upward to release the fixing of the shelf board support 1 to the support column Ra, and the shelf board is released in this state. The support 1 may be sladed to an arbitrary height position, and the support member 3 may be returned to the lower position and fixed to the support column Ra.

Then, by fixing a plurality of the shelf board supports 1 to the plurality of support columns Ra in this way, the shelf boards (not shown) can be placed and held on the plurality of support members 3. .. At this time, the lower surface of the shelf board is in contact with and supported by the curved upper surface 9a of the support portion 9.

As described above, according to the shelf board support 1 of the present embodiment, the shelf board support 1 is fixed and released from the support column Ra only by rotating the support member 3 up and down. The position of 1 can be easily adjusted.

Further, as described above, since the support portion 9 has an arch-shaped upper surface 9a, the lower surface of the shelf board is supported by line contact with any portion of the upper surface 9a. Therefore, even if the fixing points of the plurality of shelf board supports 1 with respect to the support columns Ra are slightly displaced in the vertical direction D3, the shelf boards can be stably held.

[Second Embodiment]
Next, the shelf board support according to the second embodiment of the present invention will be described. As shown in FIGS. 8 and 9, the shelf board support 101 of the present embodiment includes a fixing portion 102 detachably fixed to the support column Ra and a support member 103 for supporting the shelf board.

The fixing portion 102 includes a holder 104 and a slide portion 105 slidably held in the front-rear direction D1 with respect to the holder 104, and the support column Ra is sandwiched between the holder 104 and the slide portion 105. It is fixed to Ra.

As shown in FIGS. 10 and 11, the holder 104 includes a pair of left and right holder members 140, and the pair of holder members 140 defines a space S having a substantially rectangular shape in a plan view through which the support columns Ra are inserted. More specifically, each holder member 140 includes a rear portion 140a and a front portion 140b extending in the front-rear direction D1, an intermediate portion 140c located between the rear portion 140a and the front portion 140b, and the intermediate portion 140c is a support column Ra. It is bent in a substantially square shape in a plan view so as to spread in a tapered shape inward in the left-right direction D2 corresponding to the corner portion of. These pair of holder members 140 are connected to each other by bolts B (connectors) inserted into the rear portion 140a and screwed into the nut N. Therefore, by adjusting the tightening condition of the bolt B, the width dimension of the holder 104 in the left-right direction D2 can be adjusted. Further, the front portion 140b is located outside the rear portion 140a in the left-right direction D2, and even when the rear portions 140a are brought into contact with each other as shown in FIG. 10, the front portions 140b do not abut against each other. It is configured to have a predetermined interval.

The slide portion 105 is arranged between a pair of front portions 140b of the holder 104, and includes a slide main body portion 150 and a contact portion 155 attached to the slide main body portion 150. The slide main body portion 150 has a front plate portion 151, and an upper plate portion 152 and a lower plate portion 153 extending rearward from the upper ends and lower ends of the front plate portion 151, respectively. The left and right ends of the upper plate portion 152 extend slightly outward from the left and right ends of the rear plate portion 151 in the left-right direction D2, and the extending portions slide each rear portion 140b of the holder 104 from the vertical direction D3. It functions as flange portions F1 and F2 (FIG. 10) that are freely supported. Further, the rear ends 152a and 153a (FIG. 11) of the upper plate portion 152 and the lower plate portion 153 are cut out in a substantially square shape in a plan view corresponding to the corner portions of the support columns Ra.

The contact portion 155 extends forward from the front surface (front plate portion 151) of the slide main body portion 150, and is composed of bolts screwed into the front plate portion 151 in the present embodiment. In such a configuration, by rotating the bolt (contact portion 155), the amount of protrusion of the contact portion 155 forward from the slide main body portion 150 can be adjusted, whereby the slide portion 105 as a whole in the front-rear direction D1. The length dimension in can be adjusted. In this way, the contact portion 155 functions as a length adjusting portion.

The support member 103 is arranged between the front portions 140b of the holder 104, and is rotatably supported by the holder 104 around a swivel shaft C101 extending in the left-right direction D2. Further, as shown in FIG. 12, the support member 103 is provided with a cam curved surface 130 from the rear end to the upper surface. That is, the center point P of the cam curved surface 130 is deviated from the swivel shaft C101 of the support member 103.

In such a configuration, the support member 103 swivels around the swivel shaft C101 from the upper position (second predetermined position) shown in FIG. 12 (b) to the lower position (horizontal position, first predetermined position) shown in FIG. 12 (a). Then, since the center point P of the cam curved surface 130 moves rearward relative to the swivel axis C101, the cam curved surface 130 abuts on the contact portion 155 of the slide portion 105, and the slide portion 105 is brought into contact with the support column Ra. Press. As a result, the support column Ra is firmly sandwiched between the holder 104 and the slide portion 105, and the fixing portion 102 is fixed to the support column Ra.

Further, when the support member 103 turns from the lower position shown in FIG. 12A to the upper position shown in FIG. 12B, the center point P of the cam curved surface 130 moves forward relative to the turning axis C101. Since it moves, the cam curved surface 130 is separated from the contact portion 155, and the pressure on the support column Ra of the slide portion 105 is released.

Therefore, when adjusting the height of the shelf board support 101 with respect to the support column Ra, the support member 103 is swiveled upward to release the fixing of the shelf board support 101 to the support column Ra, and the shelf board support 101 is released. Is slid in the vertical direction D3 to an arbitrary height position, and the support member 103 may be returned to the lower position and fixed to the support column Ra. If the slide portion 105 is slid forward along the holder 104 after the fixing to the support column Ra is released, a gap is left between the support column Ra and the slide portion 105, so that the shelf board support 101 can be easily slid. , Alignment can be done more easily.

As described above, also in the shelf board support 101 of the present embodiment, the shelf board support 101 is fixed and released from the support column Ra by simply turning the support member 103 up and down. The position can be easily adjusted.

Further, in the shelf board support 101 of the present embodiment, the width dimension of the holder 104 in the left-right direction D2 and the amount of protrusion of the contact portion 155 in the front direction can be adjusted, so that the columns Ra having different thicknesses can be satisfactorily used. I can handle it.

That is, when used for a support column Ra thicker than a predetermined size, the distance between the pair of holder members 140 is adjusted according to the thickness of the support column Ra, and the width dimension of the holder 104 is adjusted. At this time, the holder members 140 are connected by bolts B in a state where the rear portions 140a do not come into contact with each other. Further, the protrusion amount of the contact portion 155 is reduced so that the fixing portion 102 is fixed to the support column Ra in the state where the support member 103 is positioned at the lower position. As a result, when the thick support member Ra is used, the support member 103 is fixed to the support member Ra before reaching the horizontal position (that is, with the support member 103 tilted diagonally forward and upward). Can be prevented.

[Third Embodiment]
Next, the shelf board support 201 according to the third embodiment of the present invention will be described with reference to FIGS. 13 and 14. Since the shelf board support 201 is similar to the shelf board support 101 described above, only the differences from the shelf board support 101 will be described here. The shelf board support 201 includes a fixing portion 202 that is detachably fixed to the support column Ra, and a support member 203 for supporting the shelf board.

The fixing portion 202 includes a holder 204 and a slide portion 205 slidably held in the front-rear direction D1 with respect to the holder 204, and the support column Ra is sandwiched between the holder 204 and the slide portion 205. It is fixed to Ra.

The holder 204 is substantially the same as the holder 104 of the second embodiment, except that a pair of left and right holder portions 240 are integrally formed and do not have a portion corresponding to the rear portion 140a. The slide portion 205 is substantially the same as the slide portion 105 of the second embodiment, but as shown in FIG. 12, the contact portion 155 is provided at the same height position as the swivel shaft C101 in the slide portion 105. On the other hand, the present embodiment is different in that the contact portion 155 is located below the swivel shaft C101 as shown in FIG.

The support member 203 is substantially the same as the support member 103 of the second embodiment, but has a cam curved surface 230 having a shape slightly different from that of the cam curved surface 130 of the second embodiment. This is because the contact portion 155 is provided below the swivel shaft C101 in the present embodiment, and when the support member 203 is positioned at the lower position shown in FIG. 14A, the cam curved surface 230 is formed. This is to make the contact portion 155 come into contact with the contact portion 155. As a result, as shown in FIG. 14A, the contact position A between the contact portion 255 and the cam curved surface 230 is located below the swivel shaft C101.

The holder 204 does not rattle even when a force that pushes down the support member 203 acts. That is, in the second embodiment, the height position of the swivel shaft C101 and the height position of the contact portion 155 (more specifically, the height position of the contact position between the contact portion 155 and the cam curved surface 130) are set. Since they match, if a force that further pushes down the support member 103 acts while the support member 103 is positioned at the lower position shown in FIG. 12 (a), the force component does not act in the front-rear direction D1. It works only in the vertical direction D3, and the holder 104 rattles. On the other hand, in the present embodiment, even when a force for further pushing down the support member 203 is applied in a state where the support member 203 is positioned at the lower position shown in FIG. 14A, the force component is in the vertical direction. Since it works on D3 and also works on D1 in the front-rear direction, rattling of the holder 204 is suppressed.

Further, in the present embodiment, the contact portion 155 is attached below the center of the slide main body portion 150 in the vertical direction D3. As a result, even if the contact portion 155 is pushed backward by the support member 203 with a strong force, the slide main body portion 150 can be prevented from being deformed. That is, in the second embodiment, since the contact portion 155 is provided at the center of the slide main body 150 in the vertical direction D3, when the contact portion 155 is pushed backward with a strong force, the slide main body 150 May be deformed in a concave shape, but in this embodiment, such deformation can be avoided.
