The operating member 33 is provided so as to be displaceable along the front-rear direction in a manner of penetrating the through hole 212a of the support block 212 provided on the inner surface of the bracket 21 supported by the movable support member 32. The operating member 33 is pressed so as to be displaced forward by a spring (pressing member) 33a interposed between the operating member 33 and the support block 212 (bracket 21), whereby the rear end portion 331 of the lever 34 is pressed. It is arranged in the front area of the contact portion 343, and the front end portion 332 projects forward from the front end portion of the bracket 21.

In the shelf support device 30 having the above configuration, the work of changing the installation height level of the product mounting shelf 20 can be performed as follows. When the operator presses the front end portion 332 of the operating member 33 backward, the operating member 33 is displaced rearward against the pressing force of the spring 33a as shown in FIGS. 8 and 9. The rear end portion 331 comes into contact with the contact portion 343, and the lever 34 in the advancing position is swung in the regressing position. As a result, the engaging piece 3421 of the lever 34 is disengaged from the engaging hole 3111, so that the engagement state between the lever 34 and the engaging hole 3111 is released, and the movable support member 32 can be raised and lowered. Since the movable support member 32 is urged upward by the constant load spring 38, there is no possibility that the movable support member 32 will immediately descend to the lower limit position.

Then, by lowering the movable support member 32 as shown in FIG. 10 against the urging force of the constant load spring 38, the engaging piece 3421 of the lever 34 swinging in the advancing posture becomes the predetermined engaging hole 3111. The installation height level of the product mounting shelf 20 can be changed by engaging the lever 34 with the engaging hole 3111, or by utilizing the urging force of the constant load spring 38. By raising the movable support member 32 as shown in 11, the engaging piece 3421 of the lever 34 swinging in the advanced posture enters the predetermined engaging hole 3111, and the lever 34 engages with the engaging hole 3111. By matching, the installation height level of the product mounting shelf 20 can be changed.

As described above, according to the shelf support device 30 according to the embodiment of the present invention, the fixed support member 31 in which a plurality of engaging holes 3111 are formed along the vertical direction has an arbitrary height of the shelf support 12b. A movable support member 32 that is fixedly arranged on the level, supports the bracket 21, and is vertically attached to the fixed support member 31 is determined by the lever 34 entering and engaging with an arbitrary engagement hole 3111. The constant load spring 38, which is arranged at the height level of the above and is interposed between the fixed support member 31 and the movable support member 32, urges the movable support member 32 upward so that the restoring force becomes a constant load. Therefore, when the engagement state between the lever 34 and the engagement hole 3111 is released, the movable support member 32 does not immediately lower to the lower limit position, and a constant load is also applied when the movable support member 32 is raised. The urging force of the spring 38 can be used, and the product storage shelf 20 can be smoothly moved up and down. As a result, the work of changing the height level of the product storage shelf 20 can be simplified.

According to the shelf support device 30, the bracket 21 is provided so as to be displaceable along the front-rear direction, and the rear end portion 331 is detached from the lever 34 by the spring 33a interposed between the bracket 21 and the front end portion 331. When the operating member 33 pressed toward the lever is displaced rearward against the pressing force of the spring 33a by operating the front end portion 332, the rear end portion 331 abuts on the lever 34 and retreats the lever 34. Since it swings to the posture, the engagement state between the lever 34 and the engagement hole 3111 can be released only by pressing the operation member 33, and the operation of changing the height level of the product mounting shelf 20 can be performed. It can be easy. In particular, since the front end portion 332 of the operating member 33 normally protrudes forward from the front end portion of the bracket 21, the operator can view the front end portion 332 protruding forward from the front end portion of the bracket 21. The operation member 33 may be pressed by applying an operating force to the product, and the operability of the work of changing the installation height level of the product mounting shelf 20 can be improved.

According to the shelf support device 30, in the lever 34, the engaging piece 3421 of the engaging portion 342 located on the lower side of the lever shaft portion 35 swings rearward about the lever shaft portion 35. When the movable support member 32 is raised, the movable support member 32 is raised in the ascending process. Even if the engaging piece 3421 enters the engaging hole 3111, the lever 34 can swing forward against the urging force of the lever spring 36 by contacting the upper end edge of the engaging hole 3111. It is possible and does not hinder the ascent of the movable support member 32.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made.

In the above-described embodiment, the operating member 33 is displaceably provided on the bracket 21, but in the present invention, the operating member is particularly arranged at the position where the lever can be swung in the regressive posture. It is not limited.
