The lower end of the support portion 44 is bent at a right angle to the inner side, and the contact portion 41 of the tilt operation member 17 is movable on the inner side above the lower end of the support portion 44.

  The operation and operation procedure of the shelf device 12 of the embodiment having the above configuration will be described. First, FIGS. 1 to 8 show the state where the shelf board 13 of the shelf device 12 is horizontal as described above. In this horizontal state, the tilt operation member 17 is in a state in which the front operation portion 39 is pulled up and the rear contact portion 41 is lowered, and the guide portion 18 is located inside the tilt operation member 17 Even if 13 is moved back and forth, the tilt operation member 17 (the contact portion 41) does not contact the guide portion 18, and the two do not interfere with each other.

  Further, the contact portion 41 at the rear of the tilt operation member 17 is held in contact with the lower end of the holding portion 44 of the shelf plate 13. As described above, since the pivot shaft 43 is located forward of the center of gravity of the tilt operation member 17, the tilt operation member 17 always tries to pivot clockwise in FIG. 3 about the pivot shaft 43. . As a result, the operating portion 39 is pulled up as described above, and the state in which the contact portion 41 is held by the holding portion 44 is maintained by the weight of the tilt operation member 17.

  When switching the shelf board 13 to the inclined state from this horizontal state (FIGS. 1 to 5), first, the stoppers 31 of the slide rails 16 on both the left and right sides are operated to release the restriction of the moving rails 28, The plate 13 is pulled forward as shown in FIGS. Next, as shown in FIGS. 9 and 10, the operation portion 39 at the front of the left and right inclined operation members 17 is pushed down.

  When the front operation portion 39 is pushed down, the inclination operation member 17 rotates counterclockwise in FIG. The inclined holding portions 42 located at the upper edge of the rear side abut on the lower surfaces of the rear portions on both sides of the shelf body 33. Further, since the tilt operation member 17 of the rear side portion of the tilt holding portion 42 is detachably attracted to the magnet 38 attached to the shelf main body 33, the state where the operation portion 39 of the tilt operation member 17 is pushed down Is held (FIG. 9, FIG. 10).

  At this time, the position of the contact portion 41 of the tilt operation member 17 is at least higher than the front end portion of the guide portion 18 as shown by the broken line arrow in FIG. 9 and 10, when the shelf board 13 is pushed into the rear display chamber 6 as shown by the broken line arrow, the fins 41A formed on the lower edge of the contact portion 41 at the rear of the inclination operation member 17 are eventually obtained. It abuts on the upper surface (sliding member 24) of the guide portion 18. Then, when the shelf board 13 is further pushed backward, the fins 41A of the contact portion 41 slide on the sliding member 24 on the upper surface of the guide portion 18, and are guided by the inclination and rise.

  At this time, since the tilt holding portion 42 of the tilt operation member 17 is in contact with the lower surface of the shelf main body 33, the tilt operation member 17 pushes up the rear portion of the shelf 13 and the shelf 13 is centered on the pivot shaft 37. It rotates counterclockwise in FIG. As a result, the rear part of the shelf board 13 is pushed higher than the front part, so that in a state where the shelf board 13 is finally stored in the display room 6, as shown in FIGS. Is low, and the rear part is switched to the high inclined state.

  When the shelf board 13 is returned to the horizontal state from such an inclined state, the shelf board 13 is pulled out again as shown in FIG. 9 and the operation portion 39 of the inclination operation member 17 is pulled up (state of FIG. 7). Thereby, the inclination operation member 17 separates from the magnet 38, and the shelf board 13 returns horizontally. In that state, the shelf board 13 may be pressed into the rear display room 6. In the process of the backward movement, the contact portion 41 of the tilt operation member 17 does not contact the guide portion 18, and the guide portion 18 is positioned inside the tilt operation member 17.

As a result, the state of the tilt operation member 17 becomes unstable, and when the tilt operation member 17 does not have to be inclined, the tilt operation member 17 does not abut the guide portion 18 either, which hinders the operation of switching the state of the shelf board 13 Can be avoided in advance.

  In this case, in the embodiment, assuming that the length dimension of the tilt operation member 17 in the front-rear direction is L, the pivot shaft 43 is forward of the center of gravity of the tilt operation member 17 and from the front end of the tilt operation member 17 Since it is located in the range behind L / 3 or more and L / 3 or more forward than the rear end, the contact portion 41 at the rear portion is maintained while maintaining the feeling of pull-up / depression operation of the operation portion 39 at the front portion. Because the variation width of the upper and lower positions is sufficiently made, the state of the shelf board 13 can be reliably switched.

  Furthermore, in the embodiment, since the holding member (magnet 38) for detachably holding the inclined operation member 17 in contact with the shelf plate 13 is provided, when switching the shelf plate 13 to the inclined state, the inclined operation member The state of the tilt operation member 17 can be held only by depressing the operation portion 39 of 17. As a result, the troublesome operation of pushing the shelf board 13 while pushing down the inclination operation member 17 can be eliminated, and the operability can be improved.

  In this case, in the embodiment, the shelf body 33 of the shelf plate 13 and the tilt operation member 17 are made of magnetic material, and the holding member is made of the magnet 38. The state of contact with the plate body 33 can be detachably held with a simple configuration.

  Furthermore, in the embodiment, a fin 41A is formed on the lower edge of the contact portion 41 of the inclination operation member 17, and the fin 41A is inclined high toward the rear, so the operation portion 39 of the inclination operation member 17 is The lower edge of the contact portion 41 bites into the guide portion 18 when the shelf board 13 is pushed in while pushing down the guide plate 18 to avoid the inconvenience such that the contact portion 41 follows the inclination of the guide portion 18 Can be moved smoothly. Thereby, the work of switching the shelf board 13 to the inclined state is facilitated.

  Further, in the embodiment, since the upper surface of the guide portion 18 is formed of the sliding member 24 made of fluorocarbon resin, the fin portion 41A of the contact portion 41 is extremely smoothly moved along the inclination of the guide portion 18 Will be able to In particular, since the fins 41A at the lower edge of the contact portion 41 are highly inclined rearward, the lower edge of the contact portion 41 can be prevented from biting into the sliding member 24 of the guide portion 18.

  In the embodiment, although both the shelf main body 33 and the inclination operation member 17 are made of magnetic materials, only one of them may be made of magnetic material and the magnet 38 may be attached to the other. Moreover, although the holding member was comprised by the magnet 38 in the Example, you may comprise not only it but what is called a catcher etc. which can be detachably hold | maintained by pushing one side into the other.
