Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a hook device for hanging a string on a box-shaped freight vehicle such as a refrigerated vehicle or a side opening/closing vehicle.

``Prior Art'' Conventionally, in box-type freight vehicles equipped with a flap body (a body with a side opening/closing door) or a freezer and a side or rear opening/closing door, cardboard boxes are stored using a forklift. In order to prevent the cargo from collapsing, hooks for hanging strings were provided in opposite directions on the opposite inner surfaces of the cargo compartment of the automobile, and strings were passed between the opposing inner surfaces to prevent the cardboard boxes from shifting or tipping. However, cardboard boxes and other cargo brought in by a forklift are likely to get caught on the hook and be damaged, and the hook protruding from the inside surface of the opening/closing door of the flap body prevents the cardboard boxes and other cargo carried in by the forklift from being caught when the door is closed. There was a risk of puncturing and damaging the cargo. In addition, in order to prevent the string from coming off the hook during the above-mentioned loosening of the string or during the tying operation, it is best to bend the end of the hook upward, but the problem is that the string easily comes off because it is bent downward or horizontally. It was hot.

``Problems to be solved by the invention'' This invention is a freight vehicle that eliminates the risk of cargo being carried into the cargo hold being damaged by the strapping hooks, reduces the risk of the straps coming off, and prevents the straps from loosening. The object of the present invention is to obtain a hook device for hanging a string.

``Means for solving the problem'' This proposal is a box-shaped cargo compartment of a truck that has an opening/closing door on the side or rear side, and a plate-shaped metal fitting is recessed on the opposite inner side, and a string is attached to the inside of the metal fitting. The base of the hook is rotatably supported around the upright shaft, the base is connected to the lower end of the upright shaft, the tip is bent upward in the same plane as the upright shaft, and the hook is The present invention is constituted by a hook device for hanging a lanyard on a freight vehicle, which is housed inside the plate-shaped fitting by force.

``Function'' Therefore, when a string is hooked to the bent part of the strap hook housed inside the dish-shaped metal fitting recessed on the opposite inner side of the box-shaped cargo compartment, the string is supported by the base of the hook. . When the string is pulled toward the indoor side, the string is caught on the upward bend, and due to the traction force, the hook rotates 90 degrees toward the indoor side around the upright axis against the spring force. (shown by phantom lines in Figure 1). When the string becomes slack, the hook rotates around the upright axis toward the inside of the plate-like metal fitting due to the force of the spring and pulls the string. When the string is not hooked to the hook, the hook is stored in the dish-shaped metal fitting by the force of the spring, and since the metal fitting is recessed on the inside surface and has no protruding part, it is difficult to carry cargo into the cargo compartment or close the side door. The hook does not touch the cargo when closing down.

"Example" A box-shaped cargo compartment 4 with a ceiling (FIGS. 3 and 4) or a box-shaped refrigerated cargo compartment in which a lift-type side opening/closing door 2 (flap) is provided on the side of the chassis 11 of a truck 1 4 (Figures 5 and 6). A rear opening/closing door 3 is provided at the rear of these cargo compartments 4. A plate-shaped metal fitting 5 having a flange 12 on the outer periphery is recessed on the opposing inner side of the cargo compartment 4, and a bolt or screw is inserted through a bolt hole 13 drilled in the flange 12 to attach the metal fitting 5. Fix it on the opposite inner surface. An upright bearing 14 is fixed to the bottom surface 5' of this metal fitting 5, an upright shaft 8 is rotatably fitted into the bearing 14, and a base 7 of a string hook 6 is integrally connected to the lower end of the upright shaft 8. The tip 9 is bent upward in the same plane as the upright shaft 8. A coil spring 10 is encircled around the outer periphery of the upright shaft 8, one end extension 10' of the spring 10 is supported by the bottom surface 5' of the metal fitting 5, and the other end extension 10'' is attached to the base of the hook 6. 7 toward the bottom surface 5', and the hook 6 is formed so as to be accommodated inside the plate-shaped metal fitting 5 by the pressing force.The portion from the bent portion of the hook 6 to the tip portion 9 is covered with a synthetic resin cushion film. , and a plurality of dish-shaped metal fittings 5 are disposed on opposing inner surfaces, and strings 15 hooked to the hooks 6, 6 are stretched between the opposing inner surfaces to store cargo such as cardboard boxes. Support with the same string to prevent the load from collapsing.In addition, the bearing 14 shown by 16 in the figure
2' in FIG. 5 is a side opening/closing door of the freezer, and 17 is a sliding prevention head of the vertical shaft 8.

``Effects'' Since the present invention is constructed as described above, there is no risk that the strapping hook 6 will protrude from the opposite inner surface of the cargo compartment 4, so there is no risk that the carried cargo will be damaged by the hook 6, and the cargo can be hooked. The string 15 is attached to the base 7 of the same hook 6.
It is safely supported by the hook 6 and there is no risk of it falling off the hook 6.
A safe hook device for hanging a string without fear of loosening when pulled through the hook 6 with a force of 1 is obtained.
