  • Patent number: 8876175
    Abstract: A door handle closure system has a positioning washer that holds a door handle in an “open” or “closed” position. The positioning washer is made of a resilient thermoplastic material, providing a positive spring feeling when the door handle reaches the opened or closed positions. The door handle (1) has a longitudinal rib (1.2) received in a cut (2.3) provided in the washer (2). In the open position, the washer (2) has external upsets which are received within two entrances (3.2) located in the fixed bushing (3). In any intermediate position, the external upsets (2.1) are dislocated from the entrances (3.2) of the fixed bushing (3), deforming part of the washer (2), so as to reduce its original diameter, in effect, loading the “spring”. In the closed position, the external upsets (2.1) are received within two entrances (3.2) located opposite thereto in the fixed bushing (3), relieving the spring pressure.

  • Patent number: 8826708
    Abstract: A locking mechanism (1) responsible for moving crossed rods for locking a door or compartment of a vehicle such as a bus, has a main cylinder (2), a fixed base (3) and articulated arms (4) equipped with rod holders (4.1). The locking mechanism herein being substantially more compact and efficient than similar mechanisms in terms of application and functionality, as the locking mechanism avoids rotating parts in the mechanism for effecting locking and unlocking, instead relying on a push/pull activation which provides many advantages.

  • Patent number: 8491020
    Abstract: A tongue latch with a protection comprising a metal part folded to form a first longitudinal extension and a second longitudinal extension, the longitudinal extension terminates with a circular form having a squared hole, wherein the second extension has a lowered edge with special cuttings to lock the protection is provided. The protection comprises a hollow part made from a plastic material with low coefficient of friction and a mouthpiece with thin walls to better adjust to the dimensions of the tongue.

  • Publication number: 20090315309
    Abstract: Disclosed herein is a tongue latch with protection comprising a metal part (1) folded in order to form two longitudinal extensions in opposite directions and in two plans (2) and (3), wherein said longitudinal extensions are connected by an slightly inclined intermediate extension (4); after a concave taper at the sides (5), said longitudinal extension (2) terminates with a circular form (6), where is provided a squared hole (7); the terminal of said opposite extension (3) has lowered edges with special cuttings (8), defining a locking system to lock the protection; said protection (9) comprises a hollow part made from a plastic material with low coefficient of friction, in the form of prism, with eight side faces formed as parallelograms and with rounded edges, having a mouthpiece with thin walls (10) to better adjust to the dimensions of the tongue; said protection (9) is connected to the terminal of the extension (3) of said tongue, where it is fitted by mechanical interference and firmly locked by the edg
