Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stretcher used for transporting luggage and the like, and more particularly to a stretcher having a rigid load receiving plate.

[0002]

[Prior art]

 A conventional stretcher with a load receiving plate is constructed by laying a rigid thick plate for receiving a load between left and right rod members, or laying a load receiving plate with a reinforcing member.

[0003]

[Problems to be solved by the invention]

 By the way, the conventional stretcher as described above has a heavy structure as a whole, and furthermore, there is a problem that it is difficult to grasp when placed on the ground or the floor because the handle portion is in close contact with the placement surface. In addition, there is also a problem that in a state where the luggage is loaded, two workers cannot be transported without grasping the handle portions of the right and left rod members before and after the stretcher. Therefore, the present invention has been devised to reduce the weight of the stretcher itself, to make it possible to easily grip the handle even when the stretcher is placed on the floor, etc. It is an object to provide a stretcher that can be moved.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the stretcher of the present invention comprises left and right rod members parallel to each other, a plurality of connecting members bridged between these rod members, and each end of the left and right rod members. A rigid load receiving plate stretched between the rod members so as to leave the handle portion, and the load receiving plate is made up of a plurality of thin plates parallel to each other and a spacer member sandwiched between the thin plates. In addition to the lightweight structure, a plurality of casters capable of horizontally supporting the load receiving plate and hooks having a smaller protrusion than the caster are provided on the back side of the load receiving plate.

In the above-described stretcher of the present invention, the rigid load receiving plate stretched between the left and right rod members has a lightweight structure in which a spacer member is sandwiched between a plurality of parallel thin plates. The weight of the stretcher as a whole is greatly reduced as compared with a conventional one having a rigid receiving plate as a rigid plate or a receiving plate with a reinforcing member.

Further, since a plurality of casters for horizontally supporting the load receiving plate are provided on the back side of the load receiving plate, when the stretcher is placed on the ground or the like, the handle portion is separated from the placing surface. Thus, there is an advantage that the grip portion can be easily grasped when lifting the stretcher.

Further, in the stretcher of the present invention, a hook having a smaller amount of protrusion than the casters is provided on the back side of the load receiving plate, and thus the stretcher is placed on the ground or the like via the casters. A single worker can use the strap to pull the stretcher, and the hook can also be used to hold the strap that restrains the load on the load receiving plate.

[0008]

[Embodiment of the invention]

 Hereinafter, a stretcher as an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view, FIG. 2 is a bottom view, FIG. 3 is a side view, and FIG. It is sectional drawing.

As shown in FIGS. 1 to 3, the stretcher according to the present embodiment comprises a connecting member 2 as two wooden square members between left and right rod members 1 and 1 as wooden round bars parallel to each other. By erection 2, the framework as a whole is formed. A rigid load receiving plate 3 is stretched between the rod members 1 and 1 so that the handle portions 1a are left at the respective ends of the rod members 1 and 1.

The load receiving plate 3 is made of paper, and has a lightweight structure including two thin plates 3a and a corrugated spacer member 3b sandwiched between the thin plates 3a as shown in FIG. However, these thin plates 3a and spacer members 3b may be made of aluminum. Further, the thin plate 3a may have three or more layers.

A rubber sponge 6 is provided on the left and right sides of the load receiving surface of the load receiving plate 3 so as to prevent the load from slipping.

In the stretcher of the present embodiment, casters 4 are further provided on both sides of each connecting member 2 on the back side of the load receiving plate 3, that is, on the left and right sides of the stretcher. A total of four are provided before and after.

A pair of left and right hooks 5 is provided on the lower surface of the connecting member 2 between the left and right casters 4, 4, and the amount of downward projection of the hooks 5 is smaller than the amount of projection of the casters 4. ing. In addition, the load receiving plate 3 has a holding portion 3c which is screwed so as to surround the rod member 1 at four corners thereof.

As a constituent material of the rod member 1 and the connecting member 2, a hollow plastic material (such as a pipe made of vinyl chloride) or bamboo may be used.

In the stretcher of the present embodiment described above, the rigid load receiving plate 3 stretched between the left and right rod members 1, 1 sandwiches the spacer member 3b between the plurality of parallel thin plates 3a. Because of its lightweight structure, the weight of the stretcher as a whole is significantly reduced as compared with conventional rigid load receiving plates with thick plates and those with a receiving plate with reinforcing members.

Since a plurality of casters 4 for horizontally supporting the load receiving plate 3 are provided on the back side of the load receiving plate 3, when the stretcher is placed on the ground or the like, the handle portion 1a of the stretcher is placed on the placing surface G. There is an advantage that the handle portion 1a can be easily gripped when lifting the stretcher.

Further, in the stretcher of the present embodiment, a hook having a smaller amount of protrusion than the caster 4 is provided on the back side of the load receiving plate 3, so that the hook 5 is placed on the ground or the like via the caster 4. The stretcher can be towed by a single worker by tying the strap, and the hook 5 can also be used for hanging the strap that restrains the load on the load receiving plate 3.

[0018]

[Effect of the invention]

 As described above, according to the stretcher of the present invention, the following effects can be obtained. (1) The rigid load receiving plate stretched between the left and right bar members has a lightweight structure in which a spacer member is sandwiched between a plurality of parallel thin plates. This will be greatly reduced compared to those with a rigid load receiving plate thick plate or those with a load receiving plate with reinforcing members. (2) Since a plurality of casters are provided on the back side of the load receiving plate to support the same load receiving plate horizontally, when the stretcher is placed on the ground or the like, the handle is separated from the loading surface. There is an advantage that it becomes a state and it becomes easy to grasp the handle portion when lifting the stretcher. (3) A hook with a smaller protrusion than the casters is provided on the back side of the load receiving plate, so that a stretcher is placed on the ground or the like via the casters and a string is attached to the hooks so that one person can Workers can tow the stretcher, and the hooks can also be used to hook a string that restrains the load on the load receiving plate.
