Description

  The present invention relates to an improvement of a loading platform for loading and unloading a load when loading or unloading a load on a truck or the like, and more particularly to a non-slip measure.

  As a loading platform as described above, there is known one in which an upper mounting surface of a platform body having an upper surface as a mounting surface is formed of a single striped steel plate (see, for example, Patent Document 1). The striped steel plate is a steel plate in which X-shaped protrusions (striped pattern) are formed continuously or discontinuously on the entire surface at a constant pitch, and a non-slip effect can be expected by the protrusions.

  In addition, as another loading platform, a plurality of panels made of an extruded material made of an Al alloy in which linear anti-slip ridges are formed are prepared, and the anti-slip ridges are arranged on the upper surface (mounting surface). In addition, there is also known a configuration in which adjacent panel edge portions are engaged and connected to each other in parallel (see, for example, Patent Document 2).

Further, for example, in a storage platform that is retractable under the floor, the platform body having the upper surface as a mounting surface is a connected body of a base end side panel and a front end side panel that can be folded and unfolded with respect to the base end side panel. In the configured type, it is not published as a patent publication, but the base side panel is made of a striped steel plate, and the front side panel is made of a light metal extruded material such as an Al alloy. A large number of non-slip ridges extending in the extrusion direction over almost the entire region may be formed.
JP 2002-114494 A (paragraph 0002) JP-A-8-318777 (FIG. 3)

  However, in Patent Document 1, a large number of X-shaped protrusions are simply formed on the upper surface of the platform body, and in Patent Document 2, a number of straight non-slip protrusions are simply parallel to the upper surface of the platform body. Therefore, the anti-slip effect is not always sufficient, and a countermeasure for improving the anti-slip effect is desired for safely performing the cargo handling work.

  Furthermore, in the folding and unfolding type loading platform, since the base end side panel is generally curved in a substantially L-shaped cross section in order to ensure rigidity, when the base end side panel is composed of a striped steel plate, In the retracted state in which the front end side panel is folded, the projections (striped pattern) formed on the vertical surface (bumper surface) of the base end side panel are exposed to the human eye and the appearance appearance is impaired. In addition, the protrusions obstruct the process, and a reflector or the like cannot be attached to the vertical surface (bumper surface) of the proximal end panel. As a solution for this, it is conceivable that the upper surface of the base side panel is formed of a striped steel plate and a flat plate without protrusions is welded to form a vertical surface (bumper surface), but this takes time. On the other hand, it is conceivable that a flat plate without projections is bent into a substantially L-shaped cross section to form a base side panel and embossed only on the upper surface to form a non-slip projection. A sufficient anti-slip effect cannot be expected just by forming the part as in Patent Documents 1 and 2.

  The present invention has been made in view of the above points. The object of the present invention is to provide a special embossing process to enhance the anti-slip effect, to have a good appearance, and to hinder the mounting of a reflector or the like. It's easy to get a loading platform that doesn't.

  In order to achieve the above object, the present invention is characterized in that a two-stage anti-slip pattern is provided.

  Specifically, the present invention is directed to a vehicle loading platform in which a load is loaded and unloaded when a load is loaded onto or unloaded from a vehicle, and the following solution is taken.

  That is, according to the first aspect of the present invention, the upper surface of the platform body is set as a mounting surface, and the mounting surface is composed of a single steel plate. The protrusions are formed by embossing, and a plurality of anti-slip recesses are engraved on the top surfaces of the anti-slip protrusions simultaneously with the embossing of the anti-slip protrusions.

  According to a second aspect of the present invention, a platform main body having an upper surface as a mounting surface is curved in a substantially L-shaped cross section, and a distal end side that can be folded and unfolded with respect to the proximal end panel. The base end side panel is made of a steel plate, and a large number of non-slip convex portions are formed on the upper surface of the base end side panel over almost the entire area by embossing. A plurality of anti-skid recesses are engraved on the top surface of the anti-slip part simultaneously with embossing of the anti-slip part.

  According to a third aspect of the present invention, in the second aspect of the present invention, the tip side panel is made of a light metal extruded material or a drawing material, and the top surface of the tip side panel has an extrusion direction or a drawing over almost the entire area. A number of anti-slip ridges extending in the direction are formed.

  According to the first aspect of the present invention, a plurality of anti-skid convex portions are formed on the upper surface of the upper surface of the platform body by embossing, and a plurality of anti-slip concave portions are further formed on the anti-slip convex portions. Since it is engraved at the same time, a two-stage anti-slip effect can be obtained, and it is sufficiently non-slip as compared to the case where a striped steel plate X-shaped protrusion or a linear anti-slip ridge is formed by extrusion. The effect can be improved.

  According to the invention according to claim 2, in the folding / development type loading platform in which at least the base end side panel is made of a steel plate, a large number of embossed portions are formed over substantially the entire upper surface of the base end side panel. Further, since a plurality of anti-slip recesses are engraved on the top surface of the anti-slip part at the same time as the embossing of the anti-slip part, a two-stage anti-slip effect can be obtained in the embossing region. As in the case of No. 1, the anti-slip effect can be sufficiently improved as compared with the case where the X-shaped protrusions of the striped steel plate or the linear anti-slip ridges formed by extrusion are formed. Furthermore, unlike the protrusions of the striped steel plate by hot rolling, the anti-slip protrusion and anti-slip recess are formed by embossing, so it is necessary to form the formation region only on the upper surface of the base side panel and prevent slipping. Therefore, even if the front panel is folded and stored, the vertical surface (bumper surface) has no non-slip projections and non-slip recesses. The appearance can be improved, and a reflector or the like can be easily attached to the vertical surface (bumper surface).

  According to the third aspect of the present invention, the tip side panel is made of the light metal extruded material or the drawn material, so that the loading platform can be made lighter accordingly. Further, the anti-slipping effect can be obtained by a large number of anti-slip ridges even on the top surface of the front panel.

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

(Embodiment 1)
FIG. 3 shows a van vehicle A as a vehicle. A box-shaped cargo bed B is mounted on a chassis frame extending in the vehicle longitudinal direction on both sides in the vehicle width direction of the van vehicle A, and a cargo handling surface is below the cargo bed floor b1. Device C is equipped. The cargo handling apparatus C includes a loading platform 1 according to Embodiment 1 of the present invention, and two sets of parallel link mechanisms 2 that cantilever-support both left and right sides of the base end of the loading platform 1. When the parallel link mechanism 2 is operated synchronously, the loading platform 1 is placed on the ground and the floor surface of the loading platform B in a state where the loading platform 1 is loaded when loading and unloading the van A. While being moved up and down in a horizontal posture with respect to the height position, the loading platform 1 is changed in posture between the horizontal posture and the vertical posture at the floor surface height position of the loading platform B during use and storage.

  At the rear end of the loading platform B, an opening b2 for taking in and out the luggage is formed, and a flip-up door b3 is provided above the opening b2. Also, rubber cushioning material b4 is provided on both the left and right sides and the lower side of the opening peripheral edge of the loading platform B, and the lower side of the door b3. When the loading platform 1 is stored in a vertical posture, the peripheral edge of the loading platform 1 is The opening b2 is closed in contact with the cushioning material b4. That is, the loading platform 1 also serves as a door.

  The loading platform 1 includes a platform body 3 having an upper surface as a placement surface, and the placement surface is made of a single steel plate such as a steel steel plate or a stainless steel plate. Two reinforcing frames 4 are provided at the same interval as the two sets of parallel link mechanisms 2.

  As a feature of the first embodiment, on the upper surface (mounting surface) of the platform main body 3, as shown in FIGS. 1 and 2, a large number of circular non-slip convex portions 5 are formed by embossing over almost the entire area. A plurality (9) of rectangular anti-slip recesses 6 are imprinted on the top surfaces of the anti-slip projections 5 simultaneously with the embossing of the anti-slip projections 5. In addition, a large number of circular recesses 7 are formed as a result of embossing the anti-skid protrusions 5 at locations corresponding to the anti-slip protrusions 5 on the lower surface of the platform body 3. The anti-slip recess 6 is shallow and the influence of its formation does not reach the circular recess 7.

  As described above, in the first embodiment, a large number of anti-slip protrusions 5 are formed by embossing over substantially the entire upper surface of the platform body 3, and a plurality of anti-slip recesses 6 are formed on the top surface of the anti-slip protrusions 5. Is stamped at the same time as the embossing of the anti-slip projection 5 so that a two-stage anti-slip effect can be obtained. The anti-slip effect can be sufficiently improved as compared with the case of forming.

(Embodiment 2)
FIG. 5 shows a van car A of a type different from that of the first embodiment. This van A is provided with two doors b5 with double doors at the rear end of the loading platform B. In addition, the loading platform 1 according to Embodiment 2 of the present invention is a three-fold type and retractable under the floor. Except this point, the second embodiment is the same as the first embodiment. That is, a cargo handling device C is provided below the floor surface of the loading platform B. The cargo handling device C is a loading platform 1 and two sets of parallel link mechanisms 2 for cantilevering the left and right sides of the loading platform 1 base end. The two sets of parallel link mechanisms 2 are operated synchronously to load and unload the load on the van A so that the load platform 1 is loaded on the load platform 1. Is raised and lowered in a horizontal posture between the ground and the floor height position of the loading platform B.

  The loading platform 1 is a connecting body of a base end side panel (bottom panel) 8 curved in a substantially L-shaped cross section and a front end side panel 9 that can be folded and unfolded with respect to the base end side panel 8. The platform main body 3 is configured, and the distal end side panel 9 includes a middle panel 10 and a top panel 11 that can be folded and unfolded with respect to the middle panel 10. That is, the base panel 8 and the middle panel 10 which are bottom panels are connected by two left and right hinges 12, and the middle panel 10 and the top panel 11 are connected by the two left and right hinges 13 so as to be foldable and unfoldable. Naturally, the two reinforcing frames 4 provided on the lower surface of the platform body 3 can be folded and unfolded in the same manner as the three panels 8, 10, and 11. FIG. 6 shows a folded / unfolded state of the loading platform 1. When the loading platform B is stored below the floor surface, the three panels 8, 10, and 11 are overlapped and folded together. Panels 8, 10, and 11 are expanded in a row. In the transition process between the storage state and the use state, the panels 8, 10, 11 are guided by the pair of guide rollers 14.

  The proximal end panel 8 is made of a steel plate such as a steel plate or a stainless steel plate. As a feature of the second embodiment, the upper surface of the base end side panel 8 has a large number of circular non-slip projections over almost the entire area as shown in FIG. 1 and FIG. 2 instead of the first embodiment. 5 is formed by embossing, and a plurality (9) of rectangular anti-slip recesses 6 are imprinted on the top surfaces of the anti-slip projections 5 simultaneously with the embossing of the anti-slip projections 5. In addition, a large number of circular recesses 7 are formed as a result of embossing the anti-skid protrusions 5 at locations corresponding to the anti-slip protrusions 5 on the lower surface of the platform body 3. However, the vertical surface (bumper surface) of the base end side panel 8 does not have the anti-slip convex portion 5 and the anti-slip concave portion 6 but constitutes a flat vertical surface (bumper surface). Thus, the reason why the non-slip projection 5 and the non-slip recess 6 can be formed only on the upper surface of the base side panel 8 is by embossing, and in the striped steel plate by hot rolling, the projections are partially formed at arbitrary locations. Can not be formed. The anti-slip recess 6 is shallow and the influence of its formation does not reach the circular recess 7 as in the first embodiment.

  Moreover, as shown in FIG. 4, the middle panel 10 and the top panel 11 which comprise the said front end side panel 9 consist of light metal extrusion materials or drawing materials, such as Al alloy, for example, and several hollow part 15 is set inside. A plurality of flat blocks 16 having a plurality of flat plates 16 are connected in parallel to form a single plate. On the top surface of the distal end side panel 9 (the middle panel 10 and the top panel 11), a large number of linear antiskid ridges 17 extending in the extrusion direction or the drawing direction are formed over almost the entire area.

  As described above, in the second embodiment, in the folding / expanding type loading platform 1 in which the base end side panel 8 is made of a steel plate, a large number of non-slip protrusions are provided over almost the entire upper surface of the base end side panel 8. 5 is formed by embossing, and a plurality of anti-slip recesses 6 are engraved on the top surfaces of the anti-slip projections 5 at the same time as the embossing of the anti-slip projections 5. The anti-slipping effect can be obtained, and, similarly to the first embodiment, the anti-slipping effect is sufficiently sufficient as compared with the case where the X-shaped protrusions of the striped steel plate or the linear anti-slip ridges formed by extrusion are formed. Can be improved.

  Furthermore, in this Embodiment 2, since the said non-slip | projection convex part 5 and the non-slip | skid recessed part 6 were formed by the embossing unlike the protrusion of the striped steel plate by hot rolling, the formation area | region is only on the upper surface of the base end side panel 8. It can be formed so as not to be formed on a vertical surface (bumper surface) that does not need to be slipped. Therefore, even if the front end side panel 9 (the middle panel 10 and the top panel 11) is folded and stored, the anti-slip convex part 5 and the anti-slip concave part 6 are not provided on the vertical surface (bumper surface), so that the appearance appearance is improved. In addition, a reflector or the like can be easily attached to the vertical surface (bumper surface).

  Moreover, in this Embodiment 2, since the front end side panel 9 (the middle panel 10 and the top panel 11) was comprised with the light metal extrusion material or the drawing material, the loading platform 1 can be made lightweight by that much. Further, even on the top surface of the distal end side panel 9, the antiskid effect can be obtained by the many antiskid ridges 17.

  In the second embodiment, the three-fold type is shown as the folding / unfolding type loading platform 1, but the two-fold type is also applicable, and only the base side panel 8 is a steel plate. However, the middle panel 10 of the front end side panel 9 may also be made of a steel plate, and the top panel 11 may also be made of a steel plate. Furthermore, the shape of the non-slip convex portion 5 is not limited to the circular shape of the first and second embodiments, and may be an ellipse, an ellipse, a rectangle, a rhombus, or a triangle, and the shape of the non-slip concave portion 6 is not limited to a rectangle. Needless to say.

  In both the first and second embodiments, the cargo handling apparatus A is applied to the rear end portion of the vehicle, but may be applied to the left end portion or the right end portion.

  The present invention is useful as a loading platform for loading and unloading a load when loading and unloading the load on a vehicle.
