Description

[Detailed Description of the Invention] [Summary] The present invention prevents the cargo on the carrier from moving around due to vibrations or falling off the carrier when the cargo is placed on the carrier of a transport vehicle and transported. Therefore, a plurality of protruding members for preventing cargo from slipping are arranged protrudingly at regular intervals on the surface of the loading platform and can be moved up and down using spring material, so that when cargo is placed on the loading platform, the protruding members protrude from the surface of the loading area. Only each protruding member lowers from the surface of the loading platform, and each of the surrounding protruding members prevents the load from shifting laterally, thereby preventing the load from shifting laterally or falling from the loading platform during transportation. This can be easily prevented.

[Industrial application field]

The present invention relates to a structure for preventing cargo from slipping on a loading platform in a transport vehicle on which cargo is placed and transported.

Generally, when carrying a small amount of cargo on a transport vehicle, there is a problem that the cargo being transported moves around on the loading platform or falls off, and these small amounts of cargo must be secured one by one with straps, etc. Because this requires such troublesome operations, there is a need for a method that prevents the cargo being transported from moving or falling off simply by placing the cargo on the loading platform without having to hang it with strings.

[Conventional technology]

FIG. 3 is a perspective view showing an example of a conventional transport trolley. In the figure, 1 is a loading platform installed on two pairs of front and rear wheels 2.2', and 3 is a handle for moving and operating the truck. And ill on the loading platform! It is known to place the cargo 4 to be transported at S and move the cart using the handle 3.

[Problem that the invention seeks to solve]

Conventionally, when a small amount of luggage 4 is placed on the above-mentioned transport vehicle and transported, there is a problem that the luggage 4 being transported moves around on the loading platform 1 or falls off the loading platform 1. For this reason, a non-slip rubber sheet 5 or the like is attached to the surface of the loading platform 10, but this is not very effective.

Since the loaded baggage 4 is carried with one hand or fixed with a string, etc., there is a problem that the carrying is complicated. This was done in light of the shortcomings of ``1-1/'', and the main point is that a small amount of cargo is simply placed on a loading platform, and the cargo moves on the loading platform during transportation. It is an object of the present invention to provide a new and simple loading prevention structure for a loading platform that prevents the loading of cargo.

[Step 1' for Solving the Problems] In order to achieve the above object, the present invention has a plurality of load slides on a loading platform 21 on which loads are placed on a Q platform such as a transport truck, as shown in FIG. Prevention i
Projecting members 22 for t are disposed on the surface of the loading platform 21 at regular intervals and protrude in a 62-state manner so as to be movable downward by 1 degree by means of an elastic member 23 that removes the tendrils from springs, etc. A mechanism for controlling the vertical movement of the load-slip prevention protrusion I422, that is, an engagement member 25 that commonly connects the lower ends of the plurality of load-slip prevention protrusions 22; The lowering operation mechanism 244, which includes an operation lever 26 with an eccentric cam 27 for lowering the protruding member 22, has a generally raised structure.

[For production]

In the load slip prevention structure of the loading platform of the present invention, the loading platform 21
A plurality of protruding members 22 for preventing load slipping are attached to the loading platform 2.
The protruding members 22 are disposed protruding from one surface at regular intervals and can be elastically movable up and down, so when a load 28 is placed on the loading platform 21, the protruding members 22 protrude from the surface of the loading area.
Since only the cargo 2B is lowered from the surface of the cargo platform 21 and surrounded by other protruding members 22, the cargo 2B
will not move or fall off the loading platform 21 during transportation. Furthermore, when it is not necessary to place the plurality of protruding members 22 for preventing load slipping on the surface of the loading platform 21, each of the protruding members 22 is lowered by operating the operating lever 26 in the direction of arrow A. 21 can be retracted from above the surface.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a cross-sectional view of a main part showing an embodiment of a cargo slip prevention structure for a loading platform according to the present invention.

In the figure, reference numeral 21 denotes a loading platform on which cargo is placed, and the loading platform 21 has a plurality of protruding members 22 for preventing cargo from slipping at regular intervals on the surface of the loading platform 21, as shown in the figure, and helical springs, etc. The elastic member 23 is arranged in a protruding state so as to be vertically movable.

Furthermore, 25 is an engagement member that commonly connects the lower end portions of the plurality of protruding members 22 for preventing load slippage, and 26 is an eccentric cam 2.
It is a control lever with 7. By operating the operating lever 26 with an eccentric cam 27 in the direction of arrow A, the retaining member 25 is horizontally lowered to move each protruding member 22 protruding onto the loading platform 21 from above the surface of the loading platform 21. It allows it to be lowered.

As shown in FIG. 2, a case will be explained in which such a cargo slip prevention structure is applied to, for example, the loading platform 21 of a hand-held transport cart equipped with two pairs of front and rear wheels 31, 31'' and a handle 32. When the cargo 2B to be transported by the transport cart is placed on the platform 21, only the protruding members 22 protruding from the surface of the loading area descend from the surface of the platform 21 due to the weight of the cargo 28, and the surrounding area is surrounded by another protruding member 22.

Therefore, the cargo 28 being transported by such a transport cart is stopped by the surrounding projecting member 22 protruding from the cargo platform 21'', and is prevented from moving around or falling off the platform 21. In addition, if the protruding members 22 protruding from the surface of the loading platform 21 become an obstacle when unloading the cargo from the loading platform 21 after transportation, or if there is no need to place each of the projecting members 22 protruding, use the operating lever. By operating 26 in the direction of arrow A, each protruding member 22 that protrudes 7 is lowered and can be retracted from the surface of the loading platform 21.

〔Effect of the invention〕

As is clear from the above explanation, according to the cargo slip prevention structure of the loading platform of the present invention, simply placing a small amount of cargo on the loading platform eliminates the need to use troublesome fixing means such as straps. (This simply prevents the load from shifting sideways or the like on the loading platform, and easily prevents the load from sliding off the loading platform due to vibrations during transportation.

Therefore, it can be used as a loading platform for various transport vehicles, trunks, etc., and is extremely advantageous.1. It has excellent practical effects.
