Description

  The present invention relates to an improvement of a vehicle loading platform, and more particularly to grounding measures.

  Since the loading platform may be damaged by the impact when the loading platform is lowered from the floor level of the loading platform in the horizontal position and comes in contact with the ground, a load made of rubber or other elastic pad is attached to the back of the platform body. A stacking platform is conventionally known (for example, see Patent Document 1). In this Patent Document 1, there is no specific disclosure on how to attach the pad to the back surface of the platform body, but typical attachment structures are illustrated in FIGS.

In this example, the loading platform a is provided with a platform body b which forms the main body, and the platform body b has six hollow panels c made of extruded materials, drawn materials, etc. arranged in parallel, and adjacent hollow panel c ends. The upper engaging portions d of the edges are engaged with each other, the lower engaging portions e are also engaged with each other, and the above-mentioned is inserted through the long insertion material f press-fitted between the upper and lower engaging portions d and e. It is formed by connecting adjacent hollow panels c to each other. On the back surface of the platform body b, two reinforcing materials g are provided in parallel so as to extend from the proximal end side to the distal end side at positions inward from both ends in the width direction. Pads h made of a rubber elastic material are attached by fastening bolts i and nuts j so as to be continuous. In the figure, k is an insert material embedded in the pad h.
JP 2001-213219 (column 0015, FIGS. 6, 9, and 10)

  However, in the above-described conventional example, the pad h is attached by fastening the bolt i and the nut j. Therefore, it takes time to install and remove, and the number of parts increases as much as the bolt i and nut j are necessary. This increases the cost.

  Further, since the pad h is only in contact with the back surface of the platform body b, the pad h may be rolled up and damaged depending on the manner of contact with the ground surface l.

  The present invention has been made in view of the above points, and an object of the present invention is to eliminate the bolts and nuts for pad attachment, thereby facilitating and reducing the cost of attachment work and removal work, and damage to the pad. Is to reduce as much as possible.

  In order to achieve the above object, the present invention is characterized in that the pad is fitted.

  Specifically, the present invention is directed to a vehicle loading platform that moves up and down between the floor height position of the loading platform and the ground in a horizontal posture, and has taken the following solutions.

That is, a first aspect of the present invention, it comprises a platform body that is extended to the front end side near the reinforcing member on the back side from the base end side to the distal side rear surface of the platform body, the rear surface of the platform body and A bottomed fitting recess that opens at both ends in the width direction is formed across the entire width of the platform body with a space from the reinforcing material, and the fitting recess is made of an elastic material that contacts the ground in a grounded state. The pad is detachably fitted and attached to the fitting recess from one end side in the width direction of the platform body so that the pad protrudes from the rear surface on the front end side of the platform body .

The invention of claim 2 is the invention according to claim 1, characterized in that it is Pas head fitted over the fitting recess length.

  According to the first aspect of the present invention, since the pad is detachably fitted and attached to the fitting recess on the back surface on the front end side of the platform body, there is no need for a bolt or nut for pad attachment, The removal work can be easily performed, and the number of parts can be reduced to provide an inexpensive loading platform.

  In addition, since the pad is housed in the fitting recess except for the portion protruding from the back surface on the front end side of the platform body, the exposed portion is less than when the pad is simply in contact with the back surface of the platform body, It is possible to reduce the damage caused by the pad rolling as much as possible.

  According to the second aspect of the present invention, since the pad is attached over the entire width of the platform body, even if the ground at the ground contact point is raised, the pad rides on the raised portion, and the raised portion becomes the loading platform. It is possible to prevent the loading platform from being damaged by not contacting the back surface of the loading platform.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 4 shows a van A as a vehicle, and a box-shaped loading platform C is mounted on a chassis frame B that extends in the vehicle longitudinal direction on both sides of the van A in the vehicle width direction. An opening c1 for taking in and out the luggage is formed at the rear end of the loading platform C, and a flip-up type door c2 is provided above the opening c1. A cargo handling device D is provided below the floor surface c3 of the loading platform C. The cargo handling device D includes a loading platform 1 according to an embodiment of the present invention, and two sets of parallel link mechanisms 2 that cantilever-support the left and right sides of the base end of the loading platform 1. By the synchronous operation of the parallel link mechanism 2, the loading platform 1 is moved up and down between the floor surface height position of the loading platform C and the ground E in a horizontal posture. Specifically, the loading platform 1 is in a stowed state in which the opening c1 is closed in a vertical posture, in a horizontal posture at a floor height position of the loading platform C, in a state of being grounded to the ground E in a horizontal posture, The postures are changed to the states shown in FIGS. 2 and 4 that are tilted and grounded to the ground E.

  As shown in FIGS. 1-3, the said loading platform 1 is provided with the platform main body 3 which makes the main body. The platform body 3 includes six hollow panels 4 made of a light metal such as an Al alloy or a drawn material, and the upper engaging portions 4a of adjacent hollow panels 4 at the edges thereof are engaged with each other. In addition, the lower engagement portions 4b are also engaged with each other, and the adjacent hollow panels 4 are connected to each other via a hollow long insertion member 5 inserted between the upper and lower engagement portions 4a and 4b. Thus, it is formed into a single plate. The long insertion material 5 is also made of a light metal extrusion material such as an Al alloy, a drawing material, or the like. In FIG. 1, reference numeral 4 c denotes a number of anti-slip ridges provided on the surface of the hollow panel 4 constituting the single platform body 3.

On the back surface of the platform body 3, two reinforcing members 6 are provided in parallel so as to extend from the proximal end side to the distal end side at positions inward from the both ends in the width direction. Further, as shown in FIG. 3, a bottomed fitting recess 7 is provided on the tip side rear surface of the platform main body 3 (in the middle of the rear surface of the most advanced hollow panel 4) with a space from the reinforcing material 6. 3 is formed in a straight line over the entire width. As shown in enlarged detail in FIG. 1, the fitting recess 7 is formed so that the opening width opened on the back surface of the platform body 3 is narrower than the back side, and the opening edges facing each other on both sides are for retaining. The engaging piece portion 7a is configured. A long pad 8 made of a rubber elastic material is detachably fitted and attached to the fitting recess 7. On both long sides of the pad 8, engaging groove portions 8a are formed over the entire length, and the pad 8 is pushed in from the one end in the width direction of the platform body 3 in correspondence with the fitting recess 7, or by pulling the other widthwise end side or we put a string-like body pad 8 to engage the engagement piece 7a of the fitting recess 7 in the engagement groove 8a of the pad 8, thereby, substantially the pad 8 Half protrudes from the rear surface of the front end side of the platform body 3 and the remaining approximately half is received in the fitting recess 7 to prevent the pad 8 from falling off from the fitting recess 7, and the pad 8 comes into contact with the ground E in the grounded state. It is like that. In addition, after the pad 8 is attached to the fitting recessed part 7 of the platform main body 3, the side plate 9 for covering opening is assembled | attached to the width direction both ends of the platform main body 3 (refer FIG. 4).

  As described above, in this embodiment, since the pad 8 is detachably fitted to the fitting recess 7 on the back surface on the front end side of the platform body 3, the mounting operation is performed without using a pad mounting bolt or nut. And can be easily removed. Further, the number of parts is reduced by the amount that bolts and nuts are not required, and the inexpensive loading platform 1 can be obtained.

  Furthermore, in this embodiment, since approximately half of the pad 8 is housed in the fitting recess 7 except for the pad 8 portion protruding from the front-end-side back surface of the platform body 3, the pad simply contacts the back surface of the platform body. As compared with the case where the pad is merely present, the exposed portion can be reduced, and damage caused by the pad rolling can be reduced as much as possible.

  In this embodiment, since the pad 8 is attached over the entire width of the platform body 3, even when the ground E at the ground contact point is raised, the pad 8 rides on the raised portion so that the raised portion is loaded. It is possible to prevent damage to the loading platform 1 without contacting the back surface of the loading platform 1.

  In addition, the application vehicle of the loading platform 1 is not limited to that of the above-described embodiment, and can be applied to, for example, an underfloor storage type or other types of vehicles.

  The present invention is useful as a grounding countermeasure for a vehicle loading platform.
