Description

DESCRIPTION

Folding stretcher

TECHNIQUE SECTOR

The present application refers to a folding, portable stretcher, which has a series of light equipment that makes it especially versatile. It is applicable in the field of medicine, aesthetics and health in general.

STATE OF THE TECHNIQUE

In the state of the art, the existence of folding stretchers is known, widely used by physiotherapists and health professionals who make home visits.

However, these stretchers do not allow automatic adjustment of the legs.

The professional needs an automatic folding stretcher whose weight is low.

The applicant does not know of any system that allows obtaining the advantages of the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a folding stretcher according to the first claim. Its different variants solve the problems outlined.

The folding wing comprises a padded useful surface, divided into two or more parts by one or more hinged folding lines, and four or more telescopic legs articulated to the useful surface. In addition, it has a control unit, a command and a motor on each leg for the extension and retraction of the leg which, according to the invention, is a linear actuator. The set is complemented by a power supply.

These linear actuators consist of a DC motor and a spindle that provides the desired linear movement.

Ideally, the stretcher includes an electronic level and the control unit is configured to modify the position of the legs to arrange the useful surface horizontally. This way the professional does not have to look for a suitable surface and can work at any point.

Other variants are seen in the rest of the memory.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, a section of drawings is included that contains the following:

Figure 1: Schematic side view of an example of a stretcher.

Figure 2: Front schematic view of the previous example.

MODES OF EMBODIMENT OF THE INVENTION

Next, a way of carrying out the invention is briefly described, as an illustrative and non-limiting example of it.

In the embodiment shown in the figures, it can be seen how the stretcher (1) represented has a useful surface (2), padded, divided into two parts by a hinged folding line. The stretcher (1) of the invention may have more divisions, holes for the head and other accessories without it being relevant to the invention.

The stretcher (1) has a series of telescopic legs (3), normally four. The legs (3) are articulatedly attached to the bottom of the useful surface (2) so that the stretcher (1) can be hidden and folded. The legs (3) at each end can be joined by crossbars (31) (not noticeable) to increase stability. Articulated braces (4) give firmness to the legs. These straps (4) are common in folding articulated stretchers and often have a structure to facilitate their removal when the stretcher (1) is to be folded, this structure being common in the art.

Each leg (3) has a linear actuator (5) to deploy or shorten it. The linear actuators (5) easily allow straight relative movement between two elements and have a very low weight.

The stretcher (1) is controlled by a control unit (6) that controls the position of the legs (3) and has at least one control (7), preferably one on each side. The control (7) includes buttons to raise and lower the height of the stretcher, for pre-programmed intermediate heights or stored in a memory of the control unit after caring for a patient, to pre-program a specific height... it being possible that the unit control (6) connects with a mobile phone application to offer more possibilities for actions. For example, the user can have the height of the stretcher (2) for each patient stored in a memory associated with the application. To do this, the stretcher (1) needs a wireless communication system, such as Bluetooth.

The stretcher (1) has a self-balancing button that serves to order the control unit (6) to find the horizontality of the useful surface (2). To do this, the stretcher (1) has an electronic level that sends the inclination to the control unit (6) and this orders each leg (3) to modify its length individually. The procedure can leave one leg (3) with a fixed length and adjust the height of the others, or calculate the average position and shorten and lengthen all legs (3).

Status lights can be incorporated to indicate if the linear actuators (5) are moving, if everything is ready for folding and collection, if the eventual battery is charged and any other information on the status of the stretcher (1).

The power source will preferably be a series of rechargeable batteries, but may have a substitute or complementary power outlet. This outlet will be connected to an AC-DC converter.

The stretcher (1) will have locks, handles, latches and other elements typical of folding stretchers.
