FR2625735A1 - Multi-function stretcher - Google Patents

Abstract

The device relates to the design of a stretcher which easily permits all types of handling operations, including two longitudinal members 1 in the shape of a T ending in handles 3 on which are fastened the carrying chains 2 and the holding chains 4 with the aid of removable attachments 5 held in the perforations located on the vertical parts 7 and in the perforations located on the horizontal parts 6 of the longitudinal members. As all the pieces are removable, the device offers multiple assembly configurations.

Description

 the multifunction stretcher.

the device concerns the design of a stretcher which easily allows all kinds of handling, for example:
By individuals - Transport of planters and basins of all shapes.

- Handling bags of soil, manure, compost, garden bins,
etc ... by allowing access to places where wheelbarrows and carts do not
can go.

- Transport of wooden logs from the cellar to the foot of the fireplace, etc ...

 By professionals - Loading / unloading of trucks.

- Entry / exit of goods on displays.

- Engine displacement.

- Transport of concrete blocks, waxes.

- All bulky but light goods (glass wool bale,
plastic, etc ...) - All goods with no manual grip.

 the stretcher can be used by four people (one for each handle) to transport heavy and / or longer objects than the stretchers.

 Although it is essential to be two for the use of this multifunction stretcher, the derriplication of the physical effort on the one hand and the possible multiplication of the load transported on the other hand, amply justify the handling to two people.

 To date, only the stretcher for medical use exists. the only handling means used are wheeled vehicles such as wheelbarrows, hand trucks, trolleys, etc. The multi-function stretcher therefore becomes a valuable aid for these vehicles and even for mechanical or electromechanical vehicles.

For example, where a traditional machine cannot be used, the stretcher intervenes to cross obstacles such as steep slope, staircase, etc ...; moreover, pebbles, tree trunks are slipped or rolled on the stretcher without effort and are, thanks to it, transported on the traditional machine.

 the object of the invention is to arrive at designing a very flexible system which can adapt to all forms of handling. To do this, the device comprises two elongated T-shaped bars acting as stretcher on which several perforations are provided allowing different adjustments of the load chains. The length of these is variable depending on the use made of it.

 Two of these chains make it possible to adjust the ecaeesent stretchers to the desired dimension and fixed to the other two chains (2) they allow the shape of the object to be transported to be automatically assumed.

 Finally, these two chains placed end to end make it possible to maintain the load transported on the stretcher.

 A non-limiting example is given of an embodiment referring to the appended drawings: - Figure 1: Developed view of the various elements.

- Figure 2: View of the mounted device.

- Figure 3, 4 and 5: View of several modes of use.

 The variant of FIG. 4 represents a rigid element fixed by bolting or screwing, through the orifices (6), the support chains passing through the orifices (7), ensuring the stability of the loads.

 Figure 5: the chains (2) support a rigid element (10) not fixed allowing the transport of an additional load.

- Figure 6: View of the folded assembly.

 Figure 1 shows the various elements that make up the device the stretcher has two beams (1) terminated at their ends by cylindrical tubes acting as handles (3). Each end of the side members is stamped in a cylindrical tube projecting from it only a few tenths and is then crimped.

This operation thus makes it possible to obtain a rounded shape in order to avoid any accidents.

 In addition, the non-closed end cap prevents the accumulation of rust and dirt of all kinds.

- Four draines (2 and 4) of different length are fixed by usual hooking means (5) in the perforations (6 and 7) of the side members.

 These are T-shaped and said perforations are positioned on the vertical part to allow the attachment of the carrying chains (2 and 4) and obtain different settings thereof.

the perforations (6) on the horizontal part (H-8) of the spar have two functions - The reception of the two chains (4) for adjusting the desired spacing of the
side rails (Figure 2).

- The possible fixing of a plate (figure 4 and 5).

 The perforations (7) on the vertical part (V-8) of the spar have three functions - Adjusting the desired length of the load chains (2) (Figure 2).

- Reception of the carrying chains (2) or (2 and 4) to constitute a branch
two-level card (Figure 5).

- Reception of the carrying chains (2) or (2 and 4) to maintain the market-
say transported (figure 4 only).

 the fasteners (5) make it possible, with the perforation / mesh or mesh / chain link combinations, to obtain the desired lengths and shapes.

 'J' - -t on the ground of traditional machines (wheelbarrows, devils, carts, etc ...) is such that, to gain space in commercial premises or even in a vehicle, the handling of goods is done "with arms".

 the weak volute of the stretcher, lower than that of a zoning broom (Figure 6) solves this problem of space.

Claims (8)

Claims 1. Load transport device intended to be used by two or more  four people or to be the auxiliary of motorized transport equipment  or not, characterized in that it comprises two housings in the form of  T on which the pipes are fixed, each of these chains bearing to  its end with a removable fastener for connecting the  so-called spars or to connect the chains together through the intermediary  perforations located on said beams. 2. Device according to claim 1 characterized in that the per  holes located on the vertical part of the side members are used to connect  the load-bearing chains (2) with the said spars. 3. Device according to claim 1 characterized in that the perfora  tions located on the horizontal part of the beams are used to connect  the chains (4) which determine the spacing and ensure the maintenance  charges. 4. Device according to claim 1 characterized in that the length  of the chains (2) and (4) is variable according to the use which is weak  you. 5. Device according to claim 1 characterized in that each  end of each of the side members is pressed into a cylindrical tube  by exceeding it only by a few tenths of Irillimeters, and  is then crimped in order to obtain at the end of the end piece thus cons  titled a rounded shape, which increases the robustness of the side members. 6. Device according to claim 1 characterized in that in a vari  ante a rigid element (9) is fixed by bolting or screwing by the in  intermediate of the orifices (6), the holding chains passing through the  holes (7), ensuring the stability of the loads. 7. Device according to claim 6, characterized in that in a va  laughing chains (2) support a rigid element (10) not fixed per-  fretting the transport of an additional load. 8. Device according to any one of the preceding claims, charac  terrified by the fact that the removable fasteners allow different  mounting combinations of the device, making connections per  boring bars / mesh of a chain or links mesh / mail  the between two chains.
