FR2761644A1 - Introduction of loaded wheeled transport utility cart into vehicle - Google Patents

Abstract

The support surface (5) of the wheeled utility cart and the reception surface (3) of the receiving vehicle have an identical constant longitudinal radius (5) arched upwards. The support surface is composed of multiple surfaces parallel to the longitudinal plane. The front zone (6) of the utility cart support surface is, before introduction, located at a height close to the rear zone (7) of the vehicle reception surface.

Description

Problem
The transport of certain numerous or heavy freight, or in bulk, requires to be previously loaded in a mobile transport utility on wheels before being introduced into a vehicle.

In this case, the introductory action comes up against a difficulty:
The plane (generally the ground) on which rests via its wheels, the utility before the introduction is not on the same plane as the platform of the vehicle on which it will have to rest after the introduction and is generally a few tens of centimeters lower. This results in compulsory handling consisting in lifting the utility to move it from one plane to another, or to allow the disassembly of its wheels.

 This is always tedious and often unrelated to the energy that an individual can produce in the case of heavy cargo.

 In addition, assuming that this handling is carried out, the utility vehicle located on the platform of the vehicle remains free to roll, which therefore involves operating its timing or its maintenance by external systems (straps, wedges, etc.). to preserve the safety of the vehicle and its passengers during transport.

 The device according to the invention overcomes these drawbacks by allowing the introduction of a utility without any other action than that of a horizontal thrust and its maintenance in the longitudinal plane once loaded into the vehicle.

 It consists of a receiving surface in the vehicle arched along a constant radius in the longitudinal plane, so that its low points are at the ends, and of a support surface on the utility vehicle arched along the same radius in the plane. longitudinal and whose front zone is substantially located at the same height as the rear zone of the receiving surface in the vehicle before introduction.

 On the action of a horizontal thrust on the utility, the advancement of the latter brings the front areas of the support surface of the utility into contact with the rear areas of the vehicle receiving surface, this of approximately tangential whatever the usual variations in vehicle height.

 Maintaining the horizontal thrust allows the utility to slide forward without requiring other efforts. The weight of the utility then rests during this momentary situation on the front of its support surface and its rear wheels. The front wheels are then lightened and detached from their original support plane.

 During the successive advance of the utility, the legs of the front wheels make contact with the rear end of the vehicle receiving surface, so that they orient themselves on the rear, then pivot around their axes of attachment to the utility before placing it in a position close to the horizontal and parallel to the longitudinal axis of the utility, outside the surfaces. The weight of the utility is then mainly supported by its support surface.

 At the end of the advance of the utility, its full weight is supported by its support surface and in such a way that the utility is in a stable position where its center of gravity is substantially vertical or on the before the highest point of the receiving surface.

According to particular embodiments:
utility support surface can be broken down into multiple surfaces
parallel to the longitudinal plane.

the receiving surface on the vehicle can be broken down into surfaces
multiples parallel to the longitudinal plane.

 The utility vehicle may have only one wheel axle.

The accompanying drawings illustrate the invention:
Figure 1 shows in section, the device of the invention.

Figure 2 shows in section, the device of the invention after introduction
utility vehicle.

 With reference to these drawings, the device comprises a receiving surface (3) in the vehicle (2) arched along a radius (4) constant in the longitudinal plane and a support surface (5) on the utility vehicle (1 ) arched along the same radius (4) in the longitudinal plane and the front zone (6) of which is substantially at the same height as the rear zone (7) of the receiving surface (3) before the utility is introduced on the vehicle.

 After introduction, the support surface (5) of the utility (1) is then in contact over its entire length with the receiving surface (3) of the vehicle (2). The center of gravity (8) of the utility is then located vertically or in front of the top (9) of the two surfaces.

 By way of nonlimiting example, the support and reception surfaces will be 1 meter long and 0.5 meters wide. The receiving surface will be coated with low friction material or rollers with transverse axes.

 The device according to the invention is particularly intended for vehicles capable of loading a utility vehicle.
