  Next, the cart in the embodiment of the present invention will be described with reference to FIGS. In the present specification, directions such as the downward direction and the left-right direction refer to directions in the installed state (stationary state) of the carriage. The carriage 10 has at least five, in this example, nine wheel support portions 2, each including a placement table 1 for placing a product, and a shaft fitting portion 22 that supports a wheel shaft 42 at a tip extending downward from the back surface of the placement table 1. Among these wheel support parts 2, at least four, in this example, nine wheels 4 are provided so as to be rotatably installed by being fitted into the shaft fitting parts 22 of the wheel support parts 2.

  In the cart of the present invention, the number of wheel support portions 2 is not limited to nine, and is appropriately determined for five or more. It is preferable that the maximum number of wheel support portions 2 is nine from the viewpoint of the maximum placement load and usage pattern of the carriage. Of the five or more wheel support portions 2, it is preferable that the four wheel support portions 2 be installed near the four corners of the mounting table 1 in terms of stable running. In the case of nine wheel support parts 2, the wheel support part 2 is spaced apart from each other in the longitudinal direction of the mounting table 1 (one side direction in the case of a regular quadrangle), and in the short direction (in the case of a regular square, the other side). It is preferable to install three places apart from each other in the side direction). That is, in the case of nine wheel support parts 2, as shown in FIG. 2, it is made into three rows of both ends and a substantially central part seeing from the front, and the three wheel support parts 2 which form each row are seen from the side. It is preferable to have three rows at both ends and a substantially central portion.

  At least four wheels 4 are installed in at least five wheel support portions 2. In the nine wheel support portions 2 as shown in FIG. 2, when there are four wheels 4, it is preferable to install them at the four wheel support portions 2, and when there are five wheels 4, the four wheel support portions 2 and the central wheel are provided. It is preferable to install on the support part 2, and when there are six wheels 4, it is preferable to install on the wheel support part 2 at the four corners and the two wheel support parts 2 at the front and rear in the center in the left-right direction, and when there are seven wheels 4 It is preferable to be installed on any one of the four corner wheel support portions 2, the two front and rear wheel support portions 2 in the center in the left-right direction, and the three wheel support portions 2 in the center in the front and rear direction. In this case, it is preferable to install on any two of the four wheel support portions 2 at the four corners, the two front and rear wheel support portions 2 at the center in the left-right direction, and the three wheel support portions 2 at the center in the front-rear direction.

  In the carriage 10, the mounting table 1 on which the product is placed may be a flat plate like this example, preferably in a substantially rectangular shape in a plan view, and in a substantially rectangular shape in a plan view. Is preferable in that it is often installed in a large space. Further, a vertical groove, a horizontal groove, a non-penetrating round hole, or the like that facilitates the installation of the display auxiliary member may be formed on the mounting surface (front surface) of the mounting table 1 at an appropriate position. The back surface of the mounting table 1 is preferably formed with thin plate-like vertical ribs and horizontal ribs in that the mounting table can be reduced in thickness while maintaining strength. In this example, it is formed of a top plate and four side plates. Moreover, the front end of the mounting table 1 is a front downward inclined surface 12, which is a rail surface for displaying product information such as products. A plate-like body 3 extending downward from the back surface and continuing in the left-right direction is formed at the front end. As a result, the wheels standing on the front side cannot be seen from the customer and the design is excellent.

The wheel support portion 2 includes a shaft fitting portion 22 that supports the wheel shaft 42 at a tip extending downward from the back surface of the mounting table 1. In this example, it consists of a pair of thin plate-like wheel support pieces 21, 21 extending downward from the back surface of the mounting table 1 and facing each other. The shaft fitting portion 22 is notched upward from the lower end, and the shaft fitting recess 221 into which the wheel shaft 42 fits from above to below, and the shaft fitting located on the tip side of the shaft fitting recess 221. The tip opening 222 has an opening (reference numeral w ₂ in FIG. 5A) smaller than the inner diameter of the recess 221, and the tip opening 222 gradually expands toward the tip side and is larger than the tip opening 222. The insertion opening 223 is formed. That is, the shape of the opening extending from the shaft fitting recess 221 to the tip is an opening shape in which the shape opposite to the shape of the shape is confronted and constricted in the middle. The insertion opening 223 facilitates passing through the wheel shaft 42, and the tip opening 222 that narrows the opening is slightly deformed on both sides so that the wheel support piece 21 widens the opening when the wheel shaft 42 is fitted. 42, the wheel shaft 42 is prevented from falling off, and the shaft fitting recess 221 can be securely fitted.

The fitting between the wheel shaft 42 and the shaft fitting recess 221 is preferably a tight fitting with no gap from the viewpoint of stable rotation of the wheel 4. That is, the outer diameter w ₁ of the wheel shaft 42 and the inner diameter w ₂ of the shaft fitting recess 221 may be the same. The mounting table 1 and the wheel support part 2 may be made of resin. In particular, the front end portion of the wheel support portion 2 is orthogonal to the thickness direction of the wheel support piece 21 (the direction in which the opening is widened) by inserting the wheel shaft 42 while maintaining strength when the wheel support portion 2 is made of resin. Allows slight deformation to.

  The wheel 4 includes a short cylindrical wheel main body 41 and a wheel shaft 42 extending to both sides at the radial center of the wheel main body 41. The wheel main body 41 and the wheel shaft 42 are integrated. For this reason, the shaft fitting recess 221 and the wheel shaft 42 are in sliding contact. The wheel 4 is preferably made of resin from the viewpoint that the sliding contact between the shaft fitting recess 221 and the wheel shaft 42 becomes smooth.

  A method of assembling the cart 10 shown in FIGS. 1 and 2 will be described. A cart body other than the wheels 4 and nine wheels 4 are prepared. In order to fit the wheels 4, the main body of the carriage is turned over and the back surface is directed upward. Next, the wheel shaft 42 of the wheel 4 is fitted into the shaft fitting portion 22 of the wheel support portion 2. As shown in FIG. 5, the insertion opening 223 of the wheel support portion 2 has a large opening so that the wheel shaft 42 of the wheel 4 can be easily inserted (FIG. 5A). Next, the wheel 4 is pushed in with a little strong force. At this time, since the opening of the tip opening 222 is smaller than the shaft diameter of the wheel shaft 42, the tip parts 23 on both sides sandwiching the opening are slightly bent in the direction orthogonal to the thickness direction and in the direction of opening the opening of the wheel support piece 21. Then, the wheel shaft 42 is passed. Then, the wheel shaft 42 enters the shaft fitting recess 221. Thus, the wheel 4 can be attached by simply fitting by pushing in without using a screw or a screwdriver. Similarly, the wheel 4 is attached to all the wheel support parts 2, and a trolley | bogie is completed.

  Next, when removing the wheel 4 from the wheel support part 2, the wheel 4 may be pulled strongly from the wheel support part 2 by hand. Thus, for example, if the wheels 4 of the central wheel support portion 2 in the front-rear direction among the three wheel support portions 2 in the center in the lateral direction and the three wheel support portions 2 on both sides are removed, the cart 10 as shown in FIG. It can be. Thus, what is necessary is just to determine the installation number of the wheels 4 according to the weight of the mounting object mounted on the trolley | bogie 10. FIG.

Further, if the size of the wheel 4 is changed, the height of the cart 10 from the base surface to the placement surface can be changed. As shown in FIG. 6, if the carriage (FIG. 6A) having the wheel 4 with the wheel diameter w ₄ is changed to the carriage having the wheel 4 a with the wheel diameter w ₅ (FIG. 6B), the mounting surface is changed. It can be increased by h minutes. Thereby, especially in the base of the goods display shelf 20, the height of a trolley | bogie can be changed according to the height of the mounting material mounted on the trolley | bogie 10. FIG.

  Although the usage method of the cart 10 is not particularly limited, for example, the use of the cart 10 in the base 125 of the merchandise display shelf 20 as shown in FIG. That is, the merchandise display shelf 20 of FIG. 7 has a multi-stage shelf plate member 123 vertically arranged on a frame assembly including a column 121 extending in the vertical direction, a laterally extending member 124 extending in the lateral direction, and a front extending member 122 extending in the front-rear direction. It was installed in. The cart 10 can be installed in the space S between the bottom shelf member 123 a of the commodity display shelf 20 and the base surface 125. That is, the product is placed on the mounting table 1 of the carriage 10 and installed in the space S. The customer can see the product on the cart 10 as it is, or pull it forward. Further, in order to replenish the product, the carriage 10 is pulled forward, the product is replenished, and moved rearward as it is. The carriage 10 is a fixed wheel and moves only in the front-rear direction. For this reason, the installation position is not disturbed. Further, since the carriage 10 is a fixed wheel and has a short moving distance, rigidity and bearings are not required as in a conventional free caster and can be manufactured at a low cost.

  In the present invention, the carriage is not limited to the above embodiment, and various modifications can be made. The wheel support portion 2 is not limited to a pair of thin plate-like wheel support pieces 21 and 21 that extend downward from the back surface of the mounting table 1 and face each other. For example, a pair of thin plate-like wheel support pieces 21, Only the distal end side of 21 has an opposing structure, and may be an integral structure on the base end side which is the mounting table 1 side. Further, the insertion opening 223 of the shaft fitting portion 22 is an optional component and can be omitted. Further, a fence that substantially surrounds the placement surface may be installed on the placement table of the carriage. Moreover, the partition plate which partitions off a goods may be installed on the mounting base of a trolley | bogie. Further, a magnet may be attached to the rear surface of the mounting table of the carriage 10. Thereby, when installing the trolley | bogie 10 in the base of the goods display shelf 20, a magnet attracts | sucks to the member of the goods display shelf 20, and fixation in a base is stabilized.

  According to the present invention, various load-bearing capacities can be exhibited, and the height from the base surface to the mounting surface of the mounting table can be changed, so that it is possible to cope with changes in the height of the mounting object. Moreover, the removal | desorption of a wheel may be easy operation by the insertion / extraction of the wheel to a shaft fitting part, and it is easy to replace | exchange a wheel and there are few burdens on an operator.
