Patent Application
20100282931
The present invention relates to a supporting element which takes the form of an angle bar. Suitable means are used to provide the bar with a wire guide sheave; the supporting elements and the sheave, together with the aforementioned means, are mounted on a guide section of the type used in window-regulating devices. Preferably, a supporting element and a sheave are provided close to each of the ends of the aforementioned section.
The supporting element itself is made up of a bar that is preferably metallic, with an angular body, the vertical part being flat, and the upper base being curved, with a central opening in its perimeter, from which a small tab protrudes perpendicular to the vertical part, while the horizontal part is concave.
On the market, there are different types of supports for sheaves that can be considered the state of the art, to fit them into guide sections in window-regulating devices; however, the function is merely that of a supporting element, unlike the supporting element that is the object of the invention, which includes other additional functions, such as:
The sheaves in window regulators lead the wire, which acts as a mechanism for dragging the window glass of the automobile; around its perimeter there is a groove that holds and guides this wire. Due to the weight of the glass and its rubbing against the joints in the frame of the window, the sheaves and their turn shaft are subject to a great deal of force, as well as the corresponding wire, which means that the bar must be very sturdy without increasing its weight very much, and the sheaves must turn with respect to the supporting element and the profile guide, without any play.
In order to fulfil the new functions, the supporting element that is the object of the invention has a ring cup on its vertical part, which serves as a support when the sheave turns, and prevents it from making lateral movements, thus preventing the wire from slipping off the sheave.
On the upper base of the vertical part, as described above, there is a perpendicular tab that, when the support is placed in the guide section, is entered in one of the drilled holes forming a circular line on the aforementioned section, and the supporting element is placed in the appropriate position in regard to the section; this is to say that the supporting element can be placed in the position desired, so it can adapt to the window-regulating device surrounding conditions or shape.
The horizontal part of the supporting element and its concave plane include a pair of openings for the fitting of the wire covers, so that it acts as a stopper for these covers and prevents the dragging of the covers inside when the wire moves.
The sheave and the supporting element are attached to the guide section by a drilled hole, into which the corresponding end is entered, acting as the shaft of the sheave, later riveted at the ends.
Other details and characteristics shall be shown throughout the description below referring to drawings attached to this report which are shown for illustrative but not limiting purposes a practical embodiment of the invention.
Below is a detailed list of the different parts of the invention which are shown in the figures attached to this report:
In one of the preferred forms of the device that is the object of the present invention, and as can be seen in
The upper base of the flat part has a semi-circular configuration, and in its central part, there is a groove (18), from the lower base of which the tab (17) sticks out perpendicularly to the aforementioned flat part (13), which fits as may be seen in
The horizontal part (14) of the supporting element (10), as can be seen in
The alignment and orientation of the supporting element (10) comes from the combination of the tab (17) with the aforementioned line of drilled holes (22) placed in the guide section (21).
The joining of the supporting element (10) to the guide section (21) comes from the shaft (20) that also acts as a rivet (20), which crosses the drilled hole (12) of (10) and the drilled hole (25) in the sheave (11), so that the supporting element (10) is fixed to the guide section (21), but the sheave (11) may turn freely around the rivet shaft (20).
The prevision of a cup (15) in the vertical part (13) of the supporting element (10) assures a gentle rubbing against the lateral surface of the sheave (11), so that said lateral surface of (11) rests on the points (16) of the cup (15), ensuring that there is not any play. Having sufficiently described this invention using the Figures attached, it is easy to understand that any changes judged to be suitable may be made, whenever these changes do not alter of the essence of the invention summarised in the following claims.
