A MODULAR SEIZING DEVICE FOR SLIDING TRACTION, FOR ROLL-UP SHUTTER BELTS

Abstract: The modular seizing device for sliding traction, for roll-up shutter belts consists of two structures (1), that may be composed during installation onto a belt (C) for the traction of a roll-up shutter, so as to realize a knob with anatomic grasping crossed by a groove (2) in which said belt slides, and inside said groove an opening (7) is performed wherein a manual pressure element (5) is housed, provided with tabs (6) for taking hold by friction onto said belt (C), and which has the function of hooking said belt along the handle.

Description: "A MODULAR SEIZING DEVICE FOR SLIDING TRACTION, FOR ROLL-UP SHUTTER BELTS" The present invention concerns a modular seizing device for sliding traction, for roll-up shutter belts, that automatically hooks the belt, considerably easing the roll-up and shut-down manoeuvres of said roll-up shutters. The difficulty in the manual seizing of the belts for performing the traction and sliding of the roll-up and shut-down of the roll-up shutters is well known. As it has been learned by common experience, no improvement has been made in the use of roll-up shutters since the invention of the same, in spite of their widespread diffusion. No simple and cheap means exist up to now - apart from expensive electromechanical devices - for make said manoeuvres of rolling up and shutting down easier. It is the aim of the present invention to facilitate the rolling up and shutting down of the roll-up shutters, providing a comfortable manual seizing that allows to make use of less energy adn without performing complicated manoeuvres, due to the automatism of a hooking along the transmission belt. The aim set forth is reached by means of the device according to the present invention, consisting of two structures that may be composed during installation onto the belt of a roll-up shutter, so as to realize o knob with anatomic grasping crossed by a groove in which said belt slides. Inside said groove a recess is performed wherein a manual pressure element is housed which has the function of hooking the belt. The evident advantages of the device according to the present invention consist in the extreme easiness, practicalness and efficiency. The device according to the present invention will be described more in detail hereinbelow relating to the enclosed drawings which show an embodiment thereof. Figure 1 shows an axonometric, transparency view of a modular seizing device for sliding traction, for roll-up shutter belts, that may be installed around the belt of a roll-up shutter. Figure 2 shows an exploded axonometric view of the components of the device according to the present invention. The enclosed figures show a modular seizing device for sliding traction, for roll-up shutter belts, mainly consisting of: - two modular structures 1 , preferably hemicylindric and/or shaped, that may be disposed around a belt C of the roll-up shutters, said belt passing through an internal groove 2 so as to obtain a handle, possibly provided with an anatomic shape, following to the reciprocal blocking performed by means of the pressure insertion of small extroverted pins 3, provided in the internal part of one of the structures, into the corresponding holes 4 performed in t h e opposite structure 1 ; - a pressure element 5, housed inside one of said structures 1 and provided with means for facilitating the hooking of the belt passing inside, like tabs 6 or other similar structure, acting by manual pressure so as to determine the squeezing of the belt C with the internal shape 8 of the opposite element 1 ; - a rectangular opening 7, or of other shape, performed in the surface of one of said structures, and through which said element 5 projects without completely coming out, due to the presence of an inclined trapezoidal shape, that determines a stop. For what concerns the functioning of the device according to the present invention, the operation of temporary blocking of the belt, necessary for performing the manoeuvres, is obtained by means of manual pressure onto said element 5, so that said tabs 6, taking hold of said belt C by friction, allow the traction thereof; when releasing said element 5, the device may be lifted along said belt C for a further traction phase. It is evident that the described blocking may be obtained also with pressure elements of differens shapes, with spheres or other, and with recesses obtained in different ways, according to the used element. Furthermore, it is possible to obtain the described effect also with a plurality of elements working in parallel. Beyond above described solution, a similar result can be obtained by means of variants which always pertain to the same action logic from which the present invention originates.

Claims: CLAIMS A modular seizing device for sliding traction, for roll- up shutter belts, characterized in: - two modular structures ( 1 ), preferably hemicylindric and/or shaped, that may be disposed around a belt (C) of the roll-up shutters, said belt passing through an internal groove (2) so as to obtain a handle, possibly provided with an anatomic shape, following to the reciprocal blocking performed by means of the pressure insertion of small extroverted pins (3), provided in the internal part of one of the structures, into the corresponding holes (4) performed in the opposite structure (1 ); - a pressure element (5), housed inside one of said structures ( 1 ) and provided with means for facilitating the hooking of the belt passing inside, like tabs (6) or other similar structure, acting by manual pressure so as to determine the squeezing of the belt (C) with the internal shape (8) of the opposite element ( 1 ); - a rectangular opening (7), or of other shape, performed in the surface of one of said structures, and through which said element (5) projects without completely coming out, due to the presence of an inclined trapezoidal shape, that determines a stop. 2. A device according to claim 1 , characterized in a pressure element (5) inside te handle, placed in a recess that allows the joint thereof with said tabs (6) for the temporary blocking action of the belt. 3. A device according to claim 1 , characterized in means (5) of different shapes and/or provided with small spheres of recesses.
