Description

[Detailed description of the invention] The present invention relates to a sheath fork that is fitted into a fork of a forklift.The sheath fork can be fitted onto the fork by slanting the upper surface of the sheath fork so that its tip faces upward. This invention relates to a sheathed fork that can prevent cargo from falling from the top of the fork while traveling, thereby ensuring safety during work.

For safety reasons, for forklifts, the rearward tilt angle of the mast is usually
It is regulated to a maximum of 12 degrees, and some with particularly large lift heights are regulated to around 6 degrees. Therefore, when transporting objects using such a forklift, especially a forklift with a large lifting height, even if the mast is tilted as far backward as possible, when the forklift suddenly brakes or makes a sudden turn, the object cannot be transported from the top of the fork. There is a risk that objects may fall, and this risk of objects falling is even more pronounced when objects such as drums that are prone to roll are being transported.

Various proposals have been made in the past for the purpose of avoiding the risk of falling objects as described above, but none of them are effective.

For example, in Utility Model Publication No. 51-17634,
A fork with a rotatable stopper attached to the tip of the fork to prevent objects from falling has been proposed, but such forks are not effective in preventing falls of various objects, especially drums. It is not fully utilized and tends to interfere with the work of unloading the transported items.

Furthermore, in Japanese Utility Model Publication No. 49-36703, a scabbard fork with a non-slip surface attached to the upper surface of the scabbard fork is proposed, but this scabbard fork has its upper surface parallel to the upper surface of the fork. Because it is fitted, it is not effective in preventing objects to be transported, such as drums, from falling when the forklift suddenly brakes or turns sharply. Further, in other proposals regarding scabbard forks, no measures have been taken to prevent the objects being transported from falling.

This invention was made in view of the above points, and by devising the internal structure of the sheath fork in particular,
To provide a sheathed fork that can effectively prevent not only objects that tend to slip off but also objects such as drums that tend to roll down when a forklift suddenly brakes or turns sharply. .

An embodiment of the sheath fork of the present invention will be described with reference to the drawings. In the drawings, 1 is a normal forklift forklift whose upper surface is horizontal and the tip of the lower surface is inclined upward; A is the fork 1; The scabbard fork of the present invention is formed by connecting left and right side plates 2 and 3 arranged slightly wider than the width with an upper plate 4 and a lower plate 5.

Thus, the sheath fork A of the present invention has an inclined plate 6 disposed inside the fork 1 in a region extending from the approximate tip of the inserted fork 1 to the front side.
2 in contact with the upper plate 4 and its tip 13 close to the lower plate 5, so that the tip of the fitted fork 1 is held between the inclined plate 6 and the lower plate 5. Therefore, when the fork 1 is fitted and used, even if the fork 1 is positioned horizontally, the upper plate 4 of the sheath fork A is tilted (tilt angle) so that the tip of the sheath fork A faces upward. :
α) in Fig. 1 can be performed (see Fig. 1).

To explain in more detail about the sheath fork A of the present invention shown in the embodiment, the inclined plate 6 has the following features in order to improve the adhesion between the inserted fork 1 and the sheath fork A.
The inclination angle is changed at the middle part 7 to form a downwardly convex dogleg shape.

In addition, in the sheath fork A of the present invention shown in the embodiment, the rear end 11 of the upper plate 4 is tilted upward to make it easier to insert the fork 1 into the sheath fork A, and the upper surface of the fork 1 The inclination angle with the upper surface of the sheath fork A can be increased.

In the figure, 8 is a rib for fixing the inclined plate 6, 9 is a connecting member, and 10 is a locking tool (not shown) for locking the sheath fork A to the inserted fork 1. These holes can have any shape. Further, it is practically suitable that the inclination angle α is 2 to 5 degrees, preferably about 2.5 degrees.

Since the scabbard fork of the present invention has the structure described above, when the scabbard fork of the present invention is used by fitting it into a fork, the tip of the sheath fork can be moved by simply positioning the fork in a horizontal position. Since the upper surface is tilted at an angle α so as to face upward, even if the mast rearward tilt angle is small, the forward movement of the transported object can be effectively prevented in combination with the rearward tilt of the mast. This is a practical feature that can ensure work safety by avoiding the risk of objects falling when the forklift suddenly brakes or makes sharp turns, even when transporting objects that are likely to fall, such as drums. be effective.
