Abstract: Of application in processes of assembly by screwing between a plastic piece and a supporting base, for example a bodywork, from which a fastener stands out perpendicularly. It is constituted by a circular base and a hexagonal body traversed by a central drilled hole which passes through and has a main segment and an expansion in which are some slightly arched internal protuberances which constitute the fastening means for connection of the nut to the fastener after a slight rotation of or pressure from the former and it determines the fastening and provisional positioning of the plastic piece with respect to the supporting base prior to its screwing. During the screwing operation the cutting effect which the metal fastener applies on the plastic walls of the drilled hole gives rise to a thread.

Abstract: Incorporates means for maintaining a constant tension in the printing ribbon (3) consisting of a loading drum (9-9') placed after the thermal print head (1) that attracts the ribbon to define a loop, thereby maintaining a constant tension throughout the printing stage to ensure the quality of this operation. The printing method consists of attracting or suctioning the printing ribbon (1) against the loading drum (9-9'), using an electrostatic system that involves creating an electric field between conductors (10) placed on the loading drum (9), or a pneumatic system that involves attracting the ribbon (1) by Venturi tubes (17) located inside the loading drum (9').

Abstract: A device, for attaching a panel to a support, incorporates a body with an elongated lower sector having a lower segment, an intermediate segment and an upper segment in which incuts are made to operatively engage and locate a retention bushing. The retention bushing has an annular head and alternated elongate and short legs that are configured to engage the lower and intermediate segments respectively when the retention bushing is at a lower position on the elongated lower sector, and configured so that the elongate legs are deflected outwardly by engagement with vertical ribs on the elongate lower sector while the short legs engage the upper segment, when the bushing is a high position on the elongate lower sector.

Abstract: A connection part between a panel and a support includes a body provided with an elongated segment that extends through an orifice made in the support. It incorporates an over-injected part made of a soft and compressible material on the body. The over-injected part has an absorption ring that envelopes a segment of the body and is in contact with a neck of retainer joined to the panel, thereby absorbing the lateral compressions resulting from positional misalignments due to manufacturing errors and expansions of the support and the panel.

Abstract: Comprises a body provided with an elongated segment that crosses an orifice made in the support, which may be a sector of a vehicle body, on the body locking a recess belonging to a retainer joined to a panel. It incorporates an overinjected part made of a soft and compressible material on the body, which is provided with an absorption ring that envelopes a segment of the body and is in contact with a neck of the retainer absorbing the lateral compressions resulting from positional misalignments due to manufacturing errors and expansions of the support and the panel.

Abstract: Applicable for connecting a panel and a support, which may be a sector of a car body. It incorporates a body with an elongated lower sector having a lower segment, an intermediate segment and an upper segment in which incuts are made to couple a retention bushing. The retention bushing comprises an annular head from where extend inferiorly some elongated legs alternated with short legs that are coupled to the lower segment and intermediate segment at a lower position corresponding to the insertion of the bushing and the body through the orifice, and are also coupled to the intermediate segment and upper segment at a higher position in which the bushing is retained with respect to the support.

Abstract: A recording deice includes a cylinder (1) of heat-sensitive ink ribbon (2), a rewinding cylinder (5), and a marking header (19). The device prevents unused segments of ribbon being left between markings. The device has a moving support (6) guiding the ribbon (2) along an additional path (16), a braking mechanism (10, 11, 12, 14) for the cylinder (1). When the ribbon (2)is tractioned and the cylinder is braked, the support (6) is forced to move against the action of an elastic element (13), reducing the additional path (16). Thus, after a marking (a-b) the ribbon and the support (6) move back to (c) so that the next marking (b-d) is made immediately after the first marking (a-b). The braking mechanism, after one or more markings, are released, unrolling a length of ribbon (2) from the cylinder, then braking again, with the process repeated.

Abstract: Applicable to machines having a moving carriage (4) that can move transversally with respect to the continuous band to be printed and that includes a thermal printing head (9) by which passes a thermal ribbon, from a cassette of origin (5) to a destination cassette (10), which pulls said ribbon (7), its characteristics centred on the fact that the drive motor for said ribbon (7) instead of being established on the moving carriage (4) is established on the fixed plate (3) along which the aforementioned carriage may travel, for which purpose said motor acts directly or indirectly on a roller (12) mounted on the fixed plate (3), aided by a return roller (14) to establish a transmission belt (14) which bends in its path due to a pair of auxiliary rollers (16-16′) mounted free to revolve about the carriage (4), by which bend the belt (13) is connected to a drive roller (15) that is also mounted on the carriage (4), which transmits the motion to the pulling cassette (10) by a transmission belt (20) and by a c

Abstract: Applicable to tapes like those employed in backpacks, handbags, cyclists' helmets and similar goods, it is constituted by means of a piece (1) injected in plastic in which are defined two bodies (2-3) connected by means of a hinge (4), these bodies coming with respective slots (8-8′) for the passage of the tape to which the termination has to be coupled, and one of said bodies (3) having side claws (6) which, through elastic, deformation of said body, can couple into complementary recesses (7) in the other body (2), in order to stabilise the clamp formed by the termination in the closed position upon the tape.

Abstract: A valve for vehicle liquid heating circuits that includes a sealed case, an inlet, an outlet and a mechanism for opening and closing at least one of said inlet and said outlet. The valve includes a guide means for mounting a member having a rack thereon and rotatable means with a toothed segment engagable with and actuating the rack along the guide means to move a valve plug into and out of engagement with a seat located at either said inlet or said outlet. A rotatable cylindrical element that includes said toothed segment extends through said sealed casing to accept a lever for actuating the segment to thereby move the rack and its associated plug.

Abstract: A one-piece plastic plug-rivet having an open frame body which is laterally expandable and having a cylindrical appendix disposed within the body and being formed with a pull shank for producing the expansion. The cylindrical appendix is provided with projection means which cooperate with a stepped aperture in the head of the plug-rivet for maintaining the body in the expanded condition.

Abstract: A one-piece plastic retaining clip for securing elongated members relative to a panel surface including a head, means for fastening the head relative to the panel surface and clip means extending from said head in a direction opposite from said fastening means. Said clip including two laterally disposed sections with the first section having a generally semi-circular or C-shaped configuration terminating at its free end in an inwardly directed flange or protuberance. The second section has its concavity facing the first section and terminates in an inwardly directed flap whose free end is generally hook-shaped whereby the elongated element is disposed within said hook-shaped portion of the flap and impinged upon by said flange in the free end of the first section to retain it in supportive relation relative to the panel.
