Description

  The present invention relates to an engagement structure for a lashing belt, and more specifically, an engagement metal fitting attached to a terminal of the lashing belt is used to engage a lashing rail provided on a cargo bed or the like of a cargo transporting vehicle. The present invention relates to an engaging structure for a lashing belt that detachably engages with a hole to fix an object to be conveyed on a loading platform.

  In order to prevent the transported object from moving or collapsing when the transported object is loaded and transported on a loading platform or container in a cargo transport vehicle such as a tilt-type or van type truck, In general, a so-called lashing belt system that is fixed and held by a lashing belt is employed. The end of the lashing belt is provided with an engagement fitting that engages with an engagement hole of a lancing rail that extends in the length direction on both inner side walls of the cargo bed, container, and the like. By engaging the tool with an arbitrary engagement hole, it can be fixed and held in accordance with the load amount of the conveyed object.

  For example, FIG. 4 is a perspective view showing a use state of a conventionally used engagement fitting 50 (see Patent Document 1), and a vertically long mounting hole 52 is formed in a bracket body bent in a U shape. The end portion of the lashing belt 10 is attached to the attachment hole 52. Further, on both sides of the engagement metal fitting 50, when the metal fitting 50 is inserted into the engagement hole 14 of the lashing rail 12, it engages with both engagement parts 14a, 14a facing each other in the engagement hole 14. Engagement pieces 26, 26 are provided, and by operating the engagement lever 18 provided on the metal fitting 50, the engagement of the engagement metal piece 50 with the rail 12 can be released.

  However, the following problems have been pointed out when the engagement fitting 50 is used. That is, for example, when the objects 40 and 40 are loaded on the loading platform 44 of the van type truck 42 and fixed and held by the lashing belt 10, the lashing belt 10 is attached to the loading platform 44 as shown in FIG. In many cases, the engagement fitting 50 is subjected to a load from an oblique direction. That is, as shown in FIG. 6, a load in the direction of the arrow along the lashing rail 12 acts on the engagement fitting 50, and the fitting 50 tilts obliquely. Therefore, the load of the object to be transported 40 is concentrated on the engagement metal fitting 50 and a part of the engagement hole 14 in contact with the metal fitting 50, and the metal fitting 50 and the engagement hole 14 are frequently deformed / damaged. was there. Further, when such deformation / breakage occurs, it is necessary to repair or replace the lashing rail 12 and the engagement metal fitting 50, which increases the cost.

Therefore, in order to solve the above problem, a mounting bracket 54 shown in FIG. 7 has been proposed (see Patent Document 2). The lashing belt mounting bracket 54 shown in the figure has two insertion portions 56, 56 that are fitted into the adjacent engagement holes 14, 14 of the lashing rail 12, and a load applied when the object 40 is fixed. Is distributed by the two insertion portions 56, 56, so that deformation and breakage of the metal fitting 54 and the lashing rail 12 can be suppressed as compared with a conventional commercial product. In addition, a connecting hole 58 is formed in the side portion of the mounting bracket 54, and when used, the commercially available engaging metal fitting 50 shown in FIG. It is designed to be inserted into and installed.

When the mounting bracket 54 is used, when the lashing belt 10 is not used, the above-described commercially available engagement bracket 50 is removed from the connection hole 58, and the mounting bracket 54 is always attached to the lashing rail 12. Accordingly, when loading and unloading the object to be transported 40, there has been a problem that a luggage cage or the like gets caught or collides with the mounting bracket 54, which interferes with the work, or the bracket 54 is damaged. Further, the mounting bracket 54 is more expensive than the commercially available engagement bracket 50, and there is a problem that the cost increases when the bracket 54 is replaced due to breakage or the like.

  That is, the present invention has been proposed in view of the above-mentioned problems inherent in the prior art described above, and has been proposed to suitably solve this problem, and prevents deformation and breakage of the fittings and lashing rails of the lashing belt. It is another object of the present invention to provide an engaging structure for a lashing belt that does not interfere with work when loading and unloading a transported object on a loading platform or a container of a cargo transporting vehicle.

In order to overcome the above-mentioned problems and achieve the intended purpose, the engaging structure of the lashing belt according to the present invention is:
A metal fitting provided on the belt end is detachably engaged with an arbitrary engagement hole of a lashing rail that extends substantially horizontally on both inner side walls of a load carrier or the like of a load carrier vehicle so that the cover on the load carrier is detachable. In the lashing belt that fixes the conveyed product,
An engagement fitting in which a through-hole portion is established in the main body portion, and an engagement piece provided at a site avoiding the through-hole portion is detachably engaged with the engagement hole;
An engagement member that can be removably inserted into the through hole of the engagement fitting, has an attachment hole for the lashing belt at one end, and a support piece that can abut against the outer surface of the lashing rail at the other end. Become
When the lashing belt is used, a load transmitted to the engagement member via the belt is dispersedly supported on the lashing rail by the engagement fitting and the support piece.

According to the engaging structure of the lashing belt according to the present invention, the load of the conveyed object transmitted through the belt is configured to be distributed to the lashing rail by the engaging metal fitting and the support piece. Can be suitably prevented. In addition, since the engaging metal fitting and the engaging member can be completely removed from the lashing rail when not in use, a load cage or the like may collide with the metal fitting when loading and unloading the object to be hindered in work. The metal fitting is not damaged. Furthermore, since the engagement metal fitting and the engagement member are formed separately, it is not necessary to replace the whole when any of them is damaged, and the cost can be reduced.

  And since the movement prevention member is provided in the said engagement member, when it penetrates the penetration opening part of the said engagement metal fitting, this engagement member does not rattle or drop off. In addition, since the support piece is configured to be detachable from the engaging member, the replacement when the support piece is broken is easy.
