Description

The present invention relates to a carriage with a detachable pallet.

Conventionally, most of the carts used for transporting luggage are of the type in which a steering handle is attached to a cart with a caster as shown in Patent Document 1, for example. This type of cart has the advantage of being able to carry a large amount of baggage alone at a time, and it is an industry where employees carry large quantities of goods such as supermarkets and home centers between warehouses and stores. Widely used. However, since this type of truck is basically loaded and unloaded with human power, the burden on the work is particularly heavy for powerless women and elderly employees. In addition, because the loading platform is in a low position, work in a middle waist posture increases, and many employees hurt their back and knees as they continue for a long time.

Many carts aimed at reducing such work burden have been proposed so far. As a typical example, for example, Patent Document 2 discloses a cart configured such that a roller is provided on a loading platform, and the loading platform is tilted when the loading / unloading is performed, and the loading is slid down. Further, Patent Document 3 shows a cart configured to load a load on a pallet having wheels and to load and unload the pallet together with a loading platform provided with a slope.

However, the invention shown in Patent Document 2 greatly contributes to reducing the work load during loading / unloading by utilizing the gravity acting on the baggage when loading / unloading the baggage. Is necessary and does not completely solve the work load problem. Further, the invention disclosed in Patent Document 3 introduces a pallet equipped with wheels, thereby making it unnecessary to lift the load when loading and unloading the load. However, the pallet loaded with the load is heavy. Therefore, even if wheels are provided, the work burden associated with raising and lowering the slope remains large.

The present invention has been made in view of the problems existing in these prior arts, and provides a pallet-equipped cart for the purpose of reducing the work load when loading and unloading loads.

The pallet-equipped trolley of the present invention includes a trolley and a pallet that is separable from the trolley, and the trolley includes a plurality of pawls whose front portions are inclined upward and arranged in the width direction at predetermined intervals. And a handle provided at the upper part of the loading platform, and a front wheel and a rear wheel provided at the lower portion of the loading platform, and the pallet includes a groove for inserting the plurality of claw portions in the front-rear direction. Yes.

This pallet-equipped cart can be separated into a pallet and a cart, and the load is not loaded directly on the cart, but loaded and unloaded while being loaded on the pallet. When loading the cargo, first tilt the carriage forward, insert the pawl into the pallet groove with the front of the carriage almost horizontal, and then gently tilt the carriage backward while loading the pallet. Slide on to move to the rear. On the other hand, when loading and unloading, the pallet is first slid on the bed and moved to the front while the cart is gently tilted forward. Next, tilt the carriage further forward to land the pallet and remove the pawl from the groove. By using this pallet-equipped trolley, it is not necessary to manually lift the load when loading, and the burden on the hips and knees is lightened. Is done. Thereby, even a weak person such as a woman or an elderly person can easily carry the luggage.

The pallet-equipped trolley of the present invention can be configured such that at least either the front end portion or the rear end portion of the upper surface of the pallet includes a stopper that protrudes upward from the other portions.

This cart with pallet tilts when loading and unloading luggage, so a stopper is provided at an appropriate position to stabilize the position of the luggage on the pallet and prevent accidents such as collapse and sliding can do.

According to the present invention, it is not necessary to manually lift the load when loading the load, and the burden on the waist and knees is lightened, so the work load is greatly reduced compared to conventional carts. Even a weak person such as a woman or an elderly person can easily carry luggage.

A cart with a pallet according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, the configuration of the pallet-equipped cart will be described with reference to FIG. The pallet-equipped cart 10 includes a cart 12 and a pallet 14. The carriage 12 and the pallet 14 are separable, and when a load is transported by the pallet-equipped carriage 10, the load is not placed directly on the carriage 12 but is placed on the carriage 12 while being placed on the pallet 14. The loading and unloading of the luggage is similarly performed while being left on the pallet 14.

The carriage 12 includes a loading platform 16, a handle 18, a front wheel 20, and a rear wheel 22. The loading platform 16 is formed in a U shape in a plan view in which two claw portions 24 are connected by a rear portion 26. The claw portion 24 is a flat plate having an equal width that is elongated in the front-rear direction of the loading platform 16 and is disposed at intervals in the width direction. An elongated space 28 is formed between the left and right claw portions 24 in the front-rear direction of the loading platform 16. One end of the space 28 is closed at the rear portion 26 of the loading platform 16, while the other end is opened forward of the loading platform 16.

The front portion 30 occupying about 2/5 of the total length of the loading platform 16 from the front end of the pawl portion 24 is at an angle of about 30 degrees upward while the other pallet mounting portion 32 and the rear portion 26 are substantially horizontal. Inclined. The front portion 30 is formed so that the thickness gradually decreases toward the tip, and the tip is chamfered. The pallet placing part 32 is a part on which the pallet 14 is placed during transportation, and is formed between the front part 30 and the rear part 26.

A rear wheel 22 is attached to the rear portion 26 of the loading platform 16. The front wheel 20 is attached to a position near the front portion 30 of the pallet placing portion 32. The front wheel 20 is attached so as not to protrude from the side of the loading platform 16 in order to avoid interference with the pallet 14.

The handle 18 is provided at a height that can be easily held by the hand when the carriage 12 is operated, and is fixed to the rear portion 26 of the loading platform 16.

The pallet 14 has a rectangular shape in plan view, and has a load mounting surface 34 with a flat upper surface. Two grooves 36 are formed on the lower surface of the pallet 14 at intervals in the width direction of the pallet 14. The groove 36 is opened on the front and rear side surfaces of the pallet 14 so that the pawl 24 of the carriage 12 can be inserted from any direction. A stopper 38 is provided at the rear end of the luggage placement surface 34. The stopper 38 has a role of preventing the load from sliding off or collapsing from the pallet 14 when the carriage 12 is tilted. The reason why the stopper 38 is provided only at the rear end is that the operator of the cart 12 is in front of the pallet 14 and can hold the load with the operator's own hand. However, the stopper 38 is also provided at the front end. , The pallet 14 can be used regardless of the front-rear direction.

Next, a method of using the pallet-equipped cart will be described with reference to FIGS. In FIG. 2, the luggage 40 to be transported is placed on the pallet 14 in advance. Here, since the operation of placing the load 40 on the pallet 14 is performed by the operator of the carriage 12 when the load 40 is transported, the operator's workload is hardly reduced. For example, a large number of loads 40 such as supermarkets and home centers are stored in the warehouse. A person who has physical strength such as a male employee of an organization whose daily work is to carry the product from the store to the store, or a male driver who has transported the luggage 40 by a truck or the like. These persons put on the plurality of pallets 14 prepared in advance while sorting the luggage 40 according to the product category and display place.

When loading the load 40, the carriage 12 is tilted forward as shown in FIG. 3, and the front portion 30 is placed in the groove 36 of the pallet 14 as shown in FIG. Insert. Then, as shown in FIG. 5, the carriage 12 is gradually recovered from the forward leaning posture, and the pallet 14 is slid on the loading platform and moved to the pallet placing portion 32. In order to make the movement of the pallet 14 smooth at this time, it is desirable to take measures to reduce the friction coefficient of the part where the pallet 14 contacts the front part 30 of the pawl part and the pallet mounting part 32. When the pallet 14 is not moved up to the pallet placement portion 32 when the carriage 12 is returned to the horizontal posture, the pallet 14 can be moved by slightly tilting the carriage 12 backward.

As shown in FIG. 6, when the pallet 14 is placed on the pallet placing part 32, the load placing surface 34 of the pallet 14 becomes substantially horizontal, and the posture of the load 40 is stabilized. In this state, the carriage 12 can be steered to carry the luggage 40.

When loading and unloading the luggage 40 after the transportation, the carriage 12 is gently tilted forward, and the pallet 14 is slid on the carriage and moved to the front portion 30. Next, the carriage 12 is further tilted forward to land the pallet 40 and the pawl 24 is removed from the groove 36.

In this way, the pallet-equipped carriage 10 uses this principle to load the load 40 by moving the front part 30 of the pawl 24 that is the action point up and down by moving the handle 18 that is the power point back and forth with the front wheel 20 as a fulcrum. And applied to unloading. For this reason, it is not necessary to manually lift the load when loading the load 40, and the load on the waist and knees is lightened. Thus, the work load has been greatly reduced as compared with the cart. Thereby, even a weak person such as a woman or an elderly person can easily carry the luggage.

The number of claw portions 24 of the pallet-equipped carriage 10 is two, but is not particularly limited to this number, and may be three or more, for example. In this case, the number and interval of the grooves 36 of the pallet 14 should be changed according to the number and interval of the pawls 24.
