BACKGROUND OF THE INVENTION
The present invention relates to a cart with casters.
[0002]
[Prior art]
In a buffet-style restaurant, a bakery corner, etc., a system is adopted in which a necessary number and a necessary amount of menus arranged on display shelves and tables are self-service. This is usually done by holding the tray in one hand and holding the tongs etc. in the other hand, taking the favorite dishes and bread etc. with the tongs etc. There must be. Since the tray is relatively large, it is unstable to hold with one hand, and as the number of articles placed on the tray increases, the overall weight increases and the tray is held horizontally with one hand. It becomes difficult. In particular, when it is necessary to work with other loads, the work is not easy, and there is a risk that the balance may be lost and the tray may be dropped.
[0003]
Therefore, in order to be able to easily move while holding the tray stably, use shopping carts used in supermarkets and service wagons used when carrying dishes to the table in restaurants etc. It is possible to do. However, conventional carts and wagons are bulky and obstructive, and these conventional ones are configured to be pushed and moved with both hands, so the balance is poor and difficult to operate with one hand. . In addition, there is a problem that it is easy to move forward and backward, but difficult to move left and right, and a small turn is not possible.
[0004]
[Problems to be solved by the invention]
It is an object of the present invention to provide a small-handed cart that can be moved freely while stably holding a tray in a buffet-type restaurant, bakery or the like.
[0005]
[Means for Solving the Problems]
* 1 The technical means of the present invention for solving the above-mentioned problems are as follows: “A cart with casters, one main shaft provided in an inclined posture rising rearward, and a body portion of the main shaft. A pair of auxiliary shafts provided so as to descend obliquely rearward from both sides from a predetermined position, a grip portion projecting horizontally and rearward from the upper end of the main shaft, and projecting forward from the vicinity of the upper end of the main shaft The caster is provided at each of a lower end portion of the main shaft and a lower end portion of the auxiliary shaft, and the tray mounting table is detached from the main shaft. It is freely mounted and has a rail portion for preventing falling at the front end and both side ends thereof ”.
[0006]
The technical means operates as follows.
One main shaft inclined backward is supported from both sides obliquely rearward by a pair of auxiliary shafts, and casters are provided at the lower ends of the main shaft and the auxiliary shaft, respectively. One of the front ends is located at the lower end portion, and the other two are arranged at the apexes of substantially isosceles triangles located at equal intervals on both sides of the main shaft. Accordingly, the cart can maintain a stable upright posture in a state where the tray or the like is placed on the tray placing table and can be moved in the posture. In order to move the cart, the grip portion is provided so as to extend horizontally from the upper end portion of the main shaft located on the center line of the cart, so that it can be easily gripped with one hand and in addition to the grip portion. The applied force can be immediately transmitted to the caster at the front end provided at the lower end of the main shaft. For example, when the wrist is moved to the left and right with the grip portion, the main shaft swings around the upper end, and at the same time, the caster located at the lower end moves to the left and right, and the cart can be directed in a desired direction. In accordance with the movement of the caster at the front end, the two rear casters move. That is, the caster at the front end of the cart easily moves in the direction of the force applied to the grip, and the movement of the caster at the front end becomes the movement of the cart. It can be moved by a desired distance in the direction of. As an example of use, for example, in a buffet-type restaurant, a tray is placed on the tray mounting table, and the cart is moved by operating the grip portion with one hand, and the table is arranged around each table. Then, take the desired food or drink with the other free hand and place it on the tray. Then just push the cart to your own table.
[0007]
Further, the tray table, since the rail portion for fall prevention at its front end and both side ends with being removably mounted on the main shaft is provided, the size of the frame portion of the cart comprising a main shaft and the auxiliary shaft Without changing the height, only the tray mounting table can be used by changing the size of the tray to the size that the rail portion surrounds according to the size of the tray or the like of each store.
[0008]
* Item 2
1 , “The tray mounting table is attached in an inclined posture rising toward the front end, and a slit having a width larger than the diameter of the main shaft is forward along the center line of the tray mounting table. `` It is formed to open '', when the other cart is pushed in the same direction from the rear of one cart, the cart located in the front is placed in the slit portion provided in the tray mounting table of the cart located rearward. As the upper end portion of the main shaft is inserted, the tray mounting table of the rear cart overlaps with the tray mounting table of the front cart.
[0009]
* 3 Item 3 In the above item 2 , “a hook portion for locking is formed on the rear surface of the main shaft, and a shelf plate portion extends between the vicinity of the lower end portion of the main shaft and the lower end portion of the auxiliary shaft. The shelf portion is provided in an inclined posture that rises rearward, and a slit having a width larger than the diameter of the main shaft is opened rearward along the center line of the shelf plate. In the case of “formed”, personal items such as bags can be locked to the hook portion or placed on the shelf portion when the cart is operated. As shown in item 3, when the carts are overlapped one after the other, the vicinity of the lower end portion of the main shaft of the cart located rearward is inserted into the slit portion formed in the shelf plate portion of the cart located forward. At the same time, the front end portion of the rear cart shelf is overlapped in a manner that slides below the rear end portion of the front cart shelf.
[0010]
【The invention's effect】
Since the present invention has the above configuration, the present invention has the following specific effects.
In a buffet-style restaurant or bakery, you can operate the cart with one hand and take the product with the other hand and put it on the tray placed on the tray mounting table. Can be carried in a stable state, and there is no inconvenience of dropping the tray or the goods on the tray during movement. Moreover, even if the weight of the product on the tray increases, it can be easily transported. Further, since the cart can be easily moved in a desired direction by a small distance with a small force applied to the grip portion, it has a small turn and can be functionally operated even in a narrow place.
[0011]
Furthermore, it can be easily changed to a tray mounting table of a size corresponding to the size of each store's tray, etc., and the tray mounted on it can be reliably prevented from falling by the rail part, so it is dedicated to each store. It will be possible to provide an easy-to-use cart.
[0012]
In item 2 , since the plurality of carts can be stacked one after the other, the carts when not in use can be stored in a low volume.
[0013]
Furthermore, in Section 3 , for example, when shopping at a bakery corner with a shopping bag at a supermarket, the shopping bag can be placed on the hook, and other personal items such as bags can be placed on the shelf. Since it can be placed on the plate part, shopping bags, bags, etc. do not get in the way during the work of selecting a desired product from the display shelf and carrying it to the tray or paying at the cash register. As with the tray mounting table, the shelf plate portion can be overlapped in the front-rear direction without interfering with the main shaft. Therefore, the shelf plate portion does not become an obstacle when the cart is overlapped in the front-rear direction when not in use.
[0014]

The net plate (14) is divided into two with a gap (15) between the auxiliary shaft (11) side and the other auxiliary shaft (12) side around the main shaft (1), The width of the gap (15) is set larger than the diameter of the main shaft (1). Also, the net plate (14) is slightly inclined so that the rear end portions respectively connected to the auxiliary shafts (11) and (12) are located above the front end portion connected to the main shaft (1). It is attached to the posture.
[0017]
A pair of insertion cylinders (16) are provided on both side surfaces in the vicinity of the bent portion at the upper end of the main shaft (1), and the insertion cylinder (16) has a tray mounting table (2) to be described later. A pair of insertion shafts (26) provided at the ends are configured to be removably inserted, and the upper end portion of the main shaft (1) is inserted by inserting the insertion shaft (26) into the insertion tube (16). The tray mounting table (2) is attached in a manner protruding forward from the vicinity. Further, two hook portions (17) for locking are provided vertically on the rear surface of the main shaft (1).
[0018]
The tray mounting table (2) is also bent in a substantially U shape so as to protrude from both sides of the first metal wire (21), which is bent in a substantially U shape, to both sides. The ends of the wide second and third metal wires (22) and (23) are connected to each other, and the hanging portions provided at both ends of the first metal wire (21) are the insertion shafts (26 ) Is set to function.
[0019]
Also, the curved portion vicinity portions of the first, second, and third metal wires (21), (22), and (23) constituting the outer side of the tray mounting table (2) are respectively bent upward to form rail portions ( 20a) (20b) (20c). The height of the arch in the rail portion (20a) located at the front end is set to be higher than the height of the grip portion (10).
[0020]
The tray mounting table (2) has a rear end corresponding to the base end portion of the insertion shaft (26) in a state where the insertion shaft (26) is inserted into the insertion tube (16) of the main shaft (1). The first metal wire (21), on which the rail part (20a) is formed, is positioned slightly upward so that the front end of the first metal wire (21) is positioned above the part.
[0021]
The tray mounting table (2) and the shelf plate part (14) are provided in an inclined posture, respectively, and the main shaft (1) is located on each lower side, so that The main shaft (1) will function as a stopper (not shown) placed on the tray mounting table (2), a product on the tray, and a personal item stopper placed on the shelf (14), There is no inconvenience that the articles placed on the tray mounting table (2) and the shelf board portion (14) in the inclined posture slide down to the side set low.
[0022]
By changing the length of the first, second, and third metal wires (21), (22), and (23), the size of the range surrounded by the rails (20a), (20b), and (20c) can be variously changed. It is possible to manufacture a tray mounting table (2) having a size that exactly matches the size of the tray used in each store where the cart is used. Since the tray mounting table (2) is detachably mounted on the insertion tube (16) of the main shaft (1) as described above, the tray mounting table of a predetermined size is not changed without changing the frame itself. By simply changing to (2), a cart dedicated to the store can be provided.
[0023]
By using the tray mounting table (2) that matches the size of the tray, each rail part of the tray mounting table (2) is placed around the tray with the tray mounted on the tray mounting table (2). (20a), (20b), and (20c) are substantially in contact with each other, and there is no inconvenience that the tray slides on the tray mounting table (2) or falls carelessly while the cart is moving.
[0024]
As described above, the tray mounting table (2) is provided in an inclined posture in which the front end is positioned higher than the rear end (base end side), and the front end of the net plate (14) is more than the rear end. The arch portion of the rail portion (20a) at the front end of the tray mounting table (2) is set to be positioned higher than the grip portion (10). Since the net plate (14) has a gap (15) wider than the diameter of the main shaft (1) so as to open rearward, when another cart is pushed in from the rear of one cart As shown in FIG. 2, the grip portion (10) of the cart located at the front is inserted below the rail portion (20a) of the rear cart and at the same time the lower end of the main shaft (1) of the rear cart. The drooping shaft portion (1a) enters the gap portion (15) of the net plate (14) of the front cart. Further, by pushing the rear cart forward, the cart placing table (2) located in the rear overlaps with the cart placing table (2) located in the front, and at the same time, the cart located in the front. The net plate (14) of the rear cart slides under the net plate (14). Thus, the rear cart is overlapped with the front cart until the front surface of the main shaft (1) of the rear cart abuts the tip of the grip portion (10) of the front cart (stacking). Therefore, when the cart is not used, the cart can be stacked in the front and rear in the manner shown in FIG.
[0025]
When this cart is used, for example, in a bakery corner of a supermarket, the cart grip portion (10) located at the end of the cart in the stacking state as described above is pulled out by hand, and the cart is loaded on the tray. A tray (not shown) is placed on the table (2). Since the size of the tray mounting table (2) is set according to the size of the tray of each store, the tray is located exactly in the rail part (20a) (20b) (20c) of the tray mounting table (2). Thus, there is no inconvenience that the tray is inadvertently dropped from the tray mounting table (2) during the movement of the cart.
