BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a clasping device for fixing a cargo item on a base by means of a belt or fastening a belt around a cargo item and, particularly, to a clasping device durable for clasping a large load such as a large size automobile.
BACKGROUND OF THE INVENTION
The present applicant has already provided a clasping device which is compact, tough, reliable in function and easy to handle (Japanese Utility Model Publication No. 56-52175). This clasping device is such that its main member is constituted by a lever so pivotally connected between a body and said main member that, when said lever is pivoted from the release position in a fastening direction, a belt turning shaft and a belt pressing shaft disposed between the walls of the lever move around said pivot shaft to fasten the belt.
The clasping device described above is intended mainly to fix an automobile on a deck aboard a ship when a relatively light-weight passenger car is to be transported aboard the ship, and accordingly, the clasping device itself is relatively compact in size.
In practice, however, it often occurs that a large vehicle of 10 tons or more is transported aboard a ship and, in such a case, the clasping device described above is not suitable. This is because, while the clasping device must be constructed tough enough to withstand the load of a vehicle of 10 tons or more, the clasping main would become very bulky if the structure of the clasping device described above were copied, and would be inconvenient to handle. That is, when the lever is pivoted to a fastening position relative to the body, the belt turning shaft and the belt pressing shaft will be positioned above the pivot shaft and, for this reason, that portion of the lever where these shafts are located project considerably upwardly from the body and, therefore, the height of the clasping main member itself in a fastening condition becomes very high, requiring the main to be constructed long in the lengthwise direction.
The present invention has been developed in the light of the above described conventional situation and has for its object to provide a novel clasping device suited for use with a large load, wherein the lever, when the clasping main is in a fastening condition, can be relatively favorably accommodated within the body and, therefore, the clasping device itself can be constructed relatively compactly.
SUMMARY OF THE INVENTION
The clasping device of the present invention is basically featured in that the lever is not directly mounted on the body, but is mounted on the body through a link so that, when the lever is pivoted relative to the body in a fastening direction, a pivot shaft connecting the link and the lever together moves in a direction in which it sinks into the body and, more particularly, is so designed that a pair of links are pivotally connected at one end by means of pivot shafts to side walls of a lever at positions exteriorly of the lever, and at the other end by means of a connecting shaft to side walls of a body at positions interiorly of the body, a first hook is connected to the connecting shaft of the body through a connecting member, a belt turning shaft and a belt pressing shaft are fixed between the side walls of the lever, and a second hook connected to the other end of a belt while one end of the belt is inserted into the lever exteriorly, turned around the belt turning shaft after having passed the belt passing shaft and led to the outside past the belt pressing shaft, said device being so designed that, when the lever is pivoted from a release position in a fastening direction, the belt turning shaft and the belt passing shaft are turned relative to the pivot shafts to fasten the belt and, at the same time, said pivot shafts move in a direction in which they sink, that is, move between the sidewalls of, the body.
According to the present invention, since in the fastening main member the lever is connected to the body not directly, but through the links, when the lever is pivoted to a fas
