    The present invention relates to an apparatus for a load carrying cart having a snow sled function in which a wheel moves without being fitted even on an uneven snow road or deep snow.

Japanese Patent Laid-Open No. 10-315983 has a sled portion that moves up and down at the bottom of the load carrying carriage, which is removable and mechanically moved up and down, and the lower portion of the wheel and the sled portion are located at the same position as required. .
Japanese Patent Application Laid-Open No. 2003-154942 has a sled portion that moves up and down at the bottom of the load carrying carriage, and a switching mechanism portion that mechanically moves up and down.
Japanese Patent Application Laid-Open No. 2011-126458 also has a sled part and a switching mechanism part that raises and lowers the same, and is mechanically combined and fixed to the lower part of the load carrying carriage so that the load carrying carriage runs on snow in a snowy road environment As a means to cope with this, both the sled and ski-like parts are mechanically combined and combined at the bottom of the cargo carrier cart.

 During transport work in which a load carrier is loaded on a snowy road during the winter period, the wheels are turned sideways due to the unevenness of the snowy road due to the swinging of the wheels with wheels on the front of the car. It becomes stuck, such as being unable to move forward as a whole, and running becomes difficult and transport becomes impossible. Also, in deep snow, the load carrying cart was buried in the snow, and it was impossible to move. In order to get out of the place where it was fitted, it was difficult to pull and push, causing collapse of the load, etc. In deep snow, the load carrying trolley was buried in the snow, and it was impossible to move. The conventional load carrying cart with a sledge mechanically assembled with metal increases in weight, and it is burdensome for the operator to carry it up and down. The present invention has been made to solve these problems.

In order to achieve such an object, the present invention is a substantially rectangular sled plate installed on the lower side of the load carrying carriage, and the front wheel of the carriage has two substantially elliptical holes that can be grounded. The load carrying carriage is characterized in that the front is curved upward and fixed by connecting means provided on the front side of the load carrying carriage, and the lower surface of the sled plate is installed above the ground contact surface of the front wheel. Snow sled.
Moreover, it is preferable to use a snow sled of the load carrying carriage characterized by having a height adjusting means between the load carrying carriage and the sled plate.
Load a plate with an angle at which the front of the plate is curved upward from the front of the load carrying carriage, and a hole is provided directly below the front wheel of the transfer carriage so that the lower part of the wheel can land directly on the ground. Place the front part of the carrier truck from the upper part to the lower part and insert the front part into the front part of the cargo carrier truck. However, the present invention provides a light weight, load-carrying trolley snow sled that can smoothly and alternately move forward even on a certain road and is excellent in traveling performance, directionality, and operability.

According to the present invention, the following effects are expected.
(1) It is easy to handle the loading and unloading work with the load carrying cart.
(2) It can flexibly handle various types of carts with different sizes.
(3) The load carrying cart can be freely and easily moved in the desired direction on the snow.
(4) The cargo cart can be operated with the same effort and operation feeling as in the snow-free season.

It is explanatory drawing of the loading platform upper part clamping board of this invention. It is explanatory drawing of the loading platform lower part sandwiching board of this invention. It is explanatory drawing of the height adjustment means of this invention. 1 is an overall perspective view showing an embodiment of the present invention.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory side view showing an embodiment of the present invention.
First, a means for connecting the loading platform upper sandwiching plate 6 to the loading platform 5 will be described.
A loading platform composed of screws or the like provided on the loading platform lower sandwiching plate 7 by sandwiching the thickness of the front end portion of the substantially rectangular loading platform 5 of the loading cart and providing a loading platform upper sandwiching plate 6 and a loading platform lower sandwiching plate 7. Thick part Adjusting to the height of the adjusting shaft 11, the base plate fixing screw 10 is brought into contact with the front portion of the base 5, and penetrates the top base plate pin hole 8 and bottom base plate shaft hole 9 with a nut 16. Tighten and fix.
Next, the warp plate 1 will be described.
As shown in FIG. 2, the warp plate 1 is a substantially rectangular plate shape, and has an angle at which the front curves upward, and a convex fitting portion 12 is provided at the front. In addition, two substantially elliptical holes 2 are provided so that the lower part of the wheeled wheel 3 can directly land on the ground. As shown in FIGS. 2 and 3, a slot 13 perpendicular to the advancing direction is provided in front of the loading platform upper sandwiching plate 6, and the convex fitting of the sled plate 1 is inserted into the slot 13. The joint portion 12 is inserted, and the sled plate 1 is fixed to the loading platform upper sandwich plate 6. At this time, the detachable fixing pin shaft 15 is inserted into the hole 14 in front of the sled plate to prevent it from coming off. A plurality of holes 14 are provided in the vertical direction, and the height is selected and adjusted.
FIG. 4 shows the loading platform lower sandwiching plate 7 and the loading platform lower clamping plate shaft hole 9 and the loading platform thickness adjusting shaft through hole 22 of the loading platform and the set screw.
Next, the height adjusting means that is the vertical position adjustment of the sled plate 1 will be described.
Two warp plate vertical adjustment plates 17 are provided in parallel on the rear side of the warp plate 1. When the sled plate up / down adjustment plate 17 is in contact with the bottom surface of the loading platform 5, the bottom surface of the sled plate is positioned above the ground contact surface of the wheel 3 with casters at an appropriate distance.
For position adjustment, while confirming that the hole 2 and the wheel 3 are aligned, insert the tip of the sled plate 1 into the groove hole 13 and fix it with the detachable fixing pin shaft 15 to span from the front upper part to the lower part of the loading platform 5. And install. As shown in FIG. 5, when the height of the sled plate vertical adjustment plate 17 is insufficient, the additional sled plate vertical adjustment plate 18 is attached.
On the rear side of the sled plate 1, the sled plate 1 is fixed by bundling the string 20 having elasticity and the string 20 having the spring 21 from the sled plate up / down adjustment plate 17 to the hand handle 19.
It is preferable that the wheel 3 with a caster is placed about 2 to 3 cm outside the hole 2 of the sled plate 1.
