FR2610577A1 - INSULATED BODY OF VAN WITH LOAD FIXING ELEMENTS - Google Patents

Abstract

THE INVENTION CONCERNS INSULATED BODIES OF VANS. IT RELATES TO AN INSULATED BODYWORK WHOSE WALLS ARE SHAPED BY A COMPOSITE MATERIAL INCLUDING A LAYER 12 OF AN INSULATING MATERIAL PLACED BETWEEN TWO RESISTANT LAYERS 8, 10. ACCORDING TO THE INVENTION, A CAVITY 4 IS FORMED ON THE SIDE OF THE INTERNAL SURFACE SO THAT A FIXING DEVICE 6 CAN BE FIXED THERE WITHOUT EXCEEDING THE INTERNAL SURFACE OF THE INTERNAL LAYER. IN THIS WAY, THE LOADING CAN BE FIXED INSIDE THE BODYWORK, WITHOUT THE FIXING DEVICE EXCEEDING IN THE LOADING SPACE.

Description

The present invention relates to the arrangement of

  load anchorage points in a refrigerated body.

managed the type of a van.

  Freight transport vehicles

  in which a load storage area is completely closed in a van body type body and in which the bodywork is formed of a composite material, are already known. The body is usually formed from panels of insulating material placed between aluminum sheets. It is important,

  for the proper restraint of cargo in these coach-

  especially when vehicles are only partially

  loaded, that the load can not move during transport, since it could then cause both damage to the load and the bodywork of the vehicle. The normal method of restraining cargo in these vehicles includes attaching load-retaining rails to the sidewalls or roof, allowing

  -the attachment of the cargo restraint.

  However, this method of retaining the load

  the load carrying capacity since the retaining rails protrude into the storage area. In addition, the retaining rails form a series of projections against which the load can abut and can be

deteriorated.

  The invention relates to a device for retaining the

  loading does not have these problems.

  A refrigerated body of the type of a van, at least a part of which is formed of a composite material,

  according to the invention, comprises at least one fixing device

  itself attached to the inner surface of the body so that load retaining members can be fixed thereto, the thickness of the body being lower at the fixing location of the fastening device, so that the device fastening does not enter the space that should contain the load in the bodywork. The fastening device preferably comprises a loading retaining rail placed substantially along the

length of the bodywork.

  The composite material advantageously comprises a first layer and a second layer separated from the first layer.

  first by a layer of insulating material.

  The thickness of the bodywork at the point of attachment

  It is preferable that the fastening device is at the level of the space of the loading space.

formed in the bodywork.

  In a preferred embodiment, the first layer defines at least a portion of the inner surface of the body and is formed of plywood. The plywood layer is coated with an reinforced plastic material

  on the side opposite to that fixed to the insulating material.

  A metal strip is placed between the insulating material and the plywood layer in the attachment region of the fastener. The second layer is formed of plywood coated with a reinforced plastic material, the opposite side to that which is attached to the insulating material. In a variant, the second layer may be formed of a metal or

of a metal alloy.

  In another embodiment, the first layer defines at least a portion of the inner surface of the body and is formed of a metal or metal alloy, such as the second layer. In a variant, the second layer may be formed of plywood coated with a reinforced plastic material, on the side opposite to that which

is attached to the insulating material.

  Other features and advantages of the invention

  tion will become more apparent from the following description,

  with reference to the accompanying drawing in which: Figure 1 is a sectional view of the side wall of a

  embodiment of refrigerated body of the type furnace

  gon according to the invention; and FIG. 2 is a sectional view of a side wall of a second refrigerated bodywork embodiment of

van type according to the invention.

  The side wall 2 of the refrigerated body of the van type is made of a composite material whose thickness is reduced to a location so that it forms a cavity 4. The depth of the cavity 4 is such that a fixing device 6 , which is fixed against the surface

  inside the refrigerated body, does not go beyond

  not in the cargo area of the van. The provision

  fixing device is maintained for example by screws

  self-tapping machines (not shown). The fixing device

  It forms hooking points of load-retaining members and preferably constitutes a load-holding rail of the type currently available and shown in FIGS. 1 and 2. The load-retaining rail is

  preferably arranged over the entire length of the van.

  The composite material which is formed at least the side walls of the refrigerated body comprises a first layer 8 and a second layer 10 separated from the first 8 by an insulating material 12. The insulating material

  can be for example a polyvinyl chloride foam.

  In the embodiment shown in FIG. 1, the first and second layers 8 and 10 are formed

  of a metal or a metal alloy, for example alumina

  minium. The metal is preferably coated with a material

  plastics so that the bodywork is insensitive to

fets of water.

  In a second embodiment shown in Figure 2, the first layer 8 which is part of the inner surface of the refrigerated body is formed of plywood coated with a layer of a reinforced plastic material 14. A metal plate 16 is placed between the plywood layer and the insulating material 12 in the

  fixing region of the rail 6 of the load.

  This metal plate is necessary because the plywood layer is not strong enough to support the load retaining rail. The second layer 10 is formed of a metal or a metal alloy, for example

  aluminum, and is coated with a plastic material.

  In a third embodiment, the arrangement is as shown in Figure 2, but the second layer is formed of plywood coated with a reinforced plastic material, the side which is not attached to the insulating material. In another variant, the first layer is formed as shown in FIG. 1, and the second

  layer is formed of coated plywood, on its ex-

  dull, of an armed plastic material.

  In all these embodiments, a bodywork

  refrigerated van is realized and, while maintaining

  loading at a suitable temperature, it can

  a maximum transport capacity of one

  loading and a device for fixing gold

cargo hold ganes.
