Abstract

Claims

1. A non-slip inflatable device for motor vehicle tires which covers the tread of the tire and which has elements on its outside face making it non-slip, and characterized because the device as such is of a low-rise straight, rectangular, elongated parallelepiped-shaped inflatable resistant element where the following elements can be observed: (1). the outside face of the device like a tread on which the non-slip elements are visible (2). the lower outside face, in contact with the outside face of the tyre (8) (3). an inflation valve for the device so that, when said device is deflated, it is easy to slide along the tire tread, to move it into its working position and once in its working position, the device is fixed in its working position with the aid of a gas bottle or manual pump, through the valve. (4). exterior non-slip protectors, secured on the outside of the device (19) consisting of plates with non-slip elements on their outside, such as nails, pyramids or any other element which may fulfill a non-slip function in friction on ice, snow or mud surfaces (5).a resistant zone consisting of an inside metal mesh covering the sides and the tread so that the effect of running does not cause the device to lose its shape in an outward direction and so lose its dynamic characteristics (6).an internal protuberances for attachment to the outside face of the tire (8), in the form of small polyhedral resistant elements able to fit into the grooves of a standard tire (7).connecting tabs on the resistant lateral faces (5) to attach external tightening components. (9).an internal reinforcements on the device, consisting of resistant material lugs located around the entire circumference of the device and high enough to prevent the two faces of the device coming into contact (10).securing components each comprising resistant strips with a cylindrical drill hole (11) in the middle and located opposite the opposing faces of the abutted ends of the device so that, when the two faces are joined, said cylindrical drill holes are axially aligned (11).a cylindrical drill hole located in the middle part of the securing elements (10). (12).a connecting pin, formed by a long screw with an enlarged head (13) and threaded at the other end. (13).a head of the connecting pin, formed by widening the pin so that its dimensions are greater than the diameter of the drill hole (10). (14).a wing-nut of the threaded close of the pin (12).

2. A non-slip inflatable device for motor vehicle tires based on a device which covers the tread of the tire and which has elements on its outside face making it non-slip as set forth in claim 1, and characterized because once the two ends of the device are joined using the attachment elements (10) or the pin (12), the device is inflated with the help of a gas bottle or a manual pump which fixes it in its working position.

A PREFERENTIAL EMBODIMENT OF THE INVENTION

[0033] The invention proposed refers to a non-slip inflatable device for motor vehicle tyres of the sort comprising a device that covers the tyre tread and which has elements on its outside face to make it non-slip. Said device is secured to the tyre under pressure when the device is inflated, said device itself consisting of a resistant element of inflatable resistant form, with a low-rise straight, rectangular, elongated parallelepiped shape, where the following elements can be made out:

[0034] (1). the outside face of the device like a tread on which the non-slip elements are visible.

[0035] (2). the lower outside face, in contact with the outside face of the tyre (8).

[0036] To prevent the device from moving as a result of the effect of the running of the tyre, protuberances (6) are included on said lower outside face (2) of the device one of which, inserted in the grooves of the tyre (8), will prevent the device from moving.

[0037] (3).inflation valve. There is an inflation valve for the device so that, when said device is deflated, it is easy to slide along the tyre tread, to move it into its working position.

[0038] Once in its working position, the device is fixed in its working position with the aid of a gas bottle or manual pump, through the valve.

[0039] (4).exterior non-slip protectors.

[0040] These protectors, secured on the outside of the device (19) consist of plates with non-slip elements on their outside, such as nails, pyramids or any other element which may fulfill a non-slip function in friction on ice, snow or mud surfaces.

[0041] (5).a resistant zone consisting of an inside metal mesh covering the sides and the tread so that the effect of running does not cause the device to lose its shape in an outward direction and so lose its dynamic characteristics.

[0042] (6).internal protuberances for attachment to the outside face of the tyre (8), in the form of small polyhedral resistant elements able to fit into the grooves of a standard tyre.

[0043] (7).connecting tabs on the resistant lateral faces (5) to attach external tightening components if needed to secure the device.

[0044] (9).internal reinforcements on the device, consisting of resistant material lugs located around the entire circumference of the device and high enough to prevent the two faces of the device coming into contact and possibly losing their characteristics.

[0045] Said reinforcements, of variable dimensions, will never prevent the circulation of the inflating air pressure.

[0046] (10).securing components each comprising resistant strips with a cylindrical drillhole (11) in the middle and located opposite the opposing faces of the abutted ends of the device so that, when the two faces are joined, said cylindrical drillholes are axially aligned.

[0047] (11).a cylindrical drillhole located in the middle part of the securing elements (10).

[0048] (12).a connecting pin, formed by a long screw with an enlarged head (13) and threaded at the other end.

[0049] (13).the head of the connecting pin, formed by widening the pin so that its dimensions are greater than the diameter of the drillhole (10).

[0050] (14).the wing-nut of the threaded close of the pin (12).

[0051] Having sufficiently described the nature of the invention and its practical implementation, it must be recorded that the foregoing specifications represented in the attached drawings may be modified in detail, provided that does not alter their fundamental principles pursuant to the previous paragraphs and summarised in the following claims.
