Abstract: A method of making interdental cleaners includes forming a slug by extruding material in a direction of extrusion to form a first slug portion having a generally rectangular first cross-section and a second slug portion having a tapering second cross-section that extends away from the rectangular first cross-section. The method also includes stamping the slug substantially perpendicular to the direction of extrusion to form a plurality of cleaner blanks. The stamping forms the first slug portions into handle portions of the cleaner blanks, and the second slug portions into shaft portions of the cleaner blanks. The shaft portions include two pairs of converging surfaces that taper toward each other to define a point. The method also includes attaching cleaning members to the ends of the shaft portions.

Abstract: The present invention is a linearly actuated rotating handrail system for escalators and moving walkways. The system includes a worm band or a handrail, having a first friction device on one side, a dragging device formed by a second friction device and coupled to the first friction device to drag the worm band in the displacement direction. The pressure device includes a first layer of kinematic support, formed by a crank, an articulated shaft, a driving connection rod, shafts and driven cranks. There is a second layer formed by traction rollers. The application of pressure to the worm band or handrail and its balanced distribution over the different pressure rollers is carried out by slides actuated by a distributor, tightened by an elastic system. The elastic system transmits the tension by a beam.

Abstract: A safety device is provided for transport systems such as walkways and stairs that include moving elements (1, 2) with longitudinal movements and in which one of the moving elements (1, 2) may undergo tilting movements in relation to an operating direction. A safety counter-guide (7) is arranged on the moving elements (1, 2) and prevents the upward tilting of the moving elements (1, 2). The safety counter-guide also includes a lower sensor (8) in the form of a band that generates a stop signal for the system upon coming into contact with moving elements (1, 2). Since the moving elements (1, 2) cannot tilt in an upwards direction, possible risks both for the user and for the mechanical system are prevented.

Abstract: The invention relates to improvements introduced in invention patent number 200602335 relating to a safety system for moving handrails comprising a plurality of moving handgrips (1), the system having a retractable stop (5) inside the railing (3), a support structure (7), joined to the railing (3), having a guide (9), a lowerable body (11) with respect to the structure (7) and having a guiding rod (12) with a runner (13) and a roller (14) moving parallel to the handgrips (1) and a driving element (15) of the body (11), one of the ends (15b) of which is rotatably connected to the support structure (7) and the other end (15a) is rotatably connected to the lowerable body (11), such that when the retractable stop (5) is pushed by the hand of the user, the rod (12) is moved and the runner (13) is released from the guide (9), the lowerable body (11) being lowered due to the effect of the driving element (15).

Abstract: The invention relates to a safety device for moving handrails consisting of a stop (5), arranged at the entrance of the handrail (1) assembled on a fixed railing (3) finishing the handrail, the stop (5) being connected to a rod (7) which can move longitudinally and is retractable against a spring (9), the device comprising a hinged outer lid (15) having locking pawls (19) for an inner lid (18), such that the outer lid (15) automatically tends to the open position due to the effect of the springs (17) affecting the hinge (16) when the stop (5) is retracted and the lock (10) of the latter are released, whereas the inner lid (18), upon being released, also tends to the open position by simple gravity. In this way when a user does not let go of the handrail (1) when it penetrates the railing (3), he or she drives the stop (5) with his or her hand and the lids (15) and (18) are automatically opened, preventing injury to the hand of the user and causing the stop of the handrail through a microswitch (23).
