Abstract

A locking device (1) for doors (P) or hatches, comprising a support member (2), a hooking lever (3) and a closing lever (4). Elastic means (5) operatively connected to the hooking lever (3) and to the closing lever (4). The closing lever (4) has a housing (A), adapted to engage with a pin (100) solidly constrained with a frame of the door (P) or hatch, and a shaped profile (6) adapted to engage with the hooking lever (3) at least when the levers (3, 4) are in the second position and third position. The support member (2) further has a locking profile (7) arranged to close a free end of the housing (A) when the levers (3, 4) are in the second position and third position.

Claims (9)

  1. A locking device (1) for doors (P) or hatches, comprising: - a support member (2); - a hooking lever (3) and a closing lever (4) operatively connected to said support member (2), said hooking lever (3) and said closing lever (4) being free to rotate with respect to each other between at least three positions, a first opening position, a second intermediate position and a third closing position; - elastic means (5) operatively connected to said hooking lever (3) and to said closing lever (4) and configured to exert a resisting moment on the rotation of said levers (3, 4); said closing lever (4) having a housing (A), adapted to engage with a pin (100) solidly constrained with a frame of said door (P) or hatch, and a shaped profile (6) adapted to engage with said hooking lever (3) at least when said levers (3, 4) are in said second position and third position; said support member (2) further having a locking profile (7) arranged to close a free end of said housing (A) when said levers (3, 4) are in said second position and third position.
  2. The locking device (1) according to claim 1, wherein said locking profile (7) has at least a first containment seat (7a) adapted to accommodate said pin (100) when said levers (3, 4) are in the second intermediate position and a second containment seat (7b) adapted to accommodate said pin (100) when said levers (3, 4) are in the third closing position.
  3. The locking device (1) according to claim 1 or 2, wherein said locking profile (7) defines at least one seat (7a, 7b) shaped like a "U" or "C" or "V" and configured to accommodate said pin (100).
  4. The locking device (1) according to one or more of the preceding claims, wherein said locking profile (7) defines, with a main portion (2a) of the support member (2), a sliding opening for said pin (100), said sliding opening being transverse to said housing (A) in each position of said levers (3, 4).
  5. The locking device (1) according to one or more of the preceding claims, wherein said shaped profile (6) defines a first step, adapted to accommodate said hooking lever (3) when said levers (3, 4) are in said second intermediate position, and a second step adapted to accommodate said hooking lever (3) when said levers (3, 4) are in said third closing position.
  6. The locking device (1) according to one or more of the preceding claims, wherein said elastic means (5) comprise a spring extending between a first end (5a), connected to said hooking lever (3), and a second end (5b), connected to said locking lever (4).
  7. The locking device (1) according to claim 6, wherein said first end (5a) is hinged to said hooking lever (3) and wherein said second end (5b) is hinged to said locking lever (4).
  8. The locking device (1) according to one or more of the preceding claims, wherein said support member (2) comprises a hooking element (2c) defining a first rotation pin (3a) for said hooking lever (3) and a second rotation pin (4a) for said locking lever (4).
  9. The locking device (1) according to claim 8, wherein said hooking lever (3) and said locking lever (4) are interposed between a main portion (2a) of said support member (2) and the hooking element (2c).

Description

The present invention relates to a snap-locking device for doors and hatches. The present device therefore applies to the field of locks and safety locks for doors or hatches, such as, for example, the doors or hatches of motor vehicles such as vans, camper vans, caravans, motor caravans, motor homes and similar. Generally, the locks are provided with elements that allow the hooking thereof to a pin that is projecting and fixed to a frame of the door. In order to overcome critical issues due to the resistance loads that the regulations associate with locks and due to any problems caused, for example, by the possible breakage of return elements such as springs or problems caused by the protrusion of certain elements of the lock or pin, it is known in the prior art to manufacture locks provided with various components having a high mechanical complexity and also a high manufacturing cost. Therefore, to date, the known locks have high manufacturing costs and therefore high maintenance or replacement costs, as well as being complex to manufacture. The technical task of the present invention is thus to provide a locking device that is capable of overcoming the drawbacks that have emerged from the prior art. An object of the present invention is therefore to provide a locking device that is lightweight and easy to manufacture. A further object of the present invention is thus to provide a locking device that is not particularly complex from a structural viewpoint. A further object of the present invention is thus to provide a locking device that is economical from a manufacturing or maintenance viewpoint. Yet another object of the present invention is to provide a locking device that responds to high resistance loads, guaranteeing high operating standards. The stated technical task and specified objects are substantially achieved by a locking device comprising the technical features disclosed in one or more of the appended claims. The dependent claims correspond to possible embodiments of the invention. In particular, the stated technical task and specified objects are substantially achieved by a locking device for doors or hatches comprising a support member, a hooking lever, a closing lever and elastic means. According to an aspect of the present invention, the hooking lever and the closing lever are operatively connected to the support member. The hooking lever and the closing lever are free to rotate with respect to each other between at least three positions, a first opening position, a second intermediate (or semi-closed) position and a third closing position. According to an aspect of the invention, the elastic means (or elastic return means) are operatively connected to the hooking lever and to the closing lever and configured to exert a resisting moment on the rotation of said levers. According to an aspect of the invention, the closing lever has a housing, adapted to engage with a pin solidly constrained with a frame of the door or hatch, and a shaped profile adapted to engage with the hooking lever at least when the levers are in the second position and third position. Preferably, the housing has a rectilinear shape, i.e. without bends or intermediate housings along the extension thereof. According to an aspect of the invention, the support member also has a locking profile arranged to close a free end of the housing when the levers are in the second position and third position. Advantageously, the presence of the locking profile allows the obtaining of a lightweight and economical locking device that does not require complex and costly components to overcome the known problems of the prior art. Additional features and advantages of the present invention will emerge more clearly from the indicative and thus non-limiting description of an embodiment of a locking device. Such description will be set forth herein below with reference to the accompanying drawings, provided for merely indicative and therefore non-limiting purposes, wherein: Figure 1 is a schematic representation of the locking device in a first operating configuration;Figure 2 is a schematic representation of the locking device in a second operating configuration;Figure 3 is a schematic representation of the locking device in a third operating configuration. With reference to the appended figures, the number 1 indicates, in its entirety, a locking device for doors or hatches which, for simplicity of description, will be referred to below as the device 1. In particular, the door "P" or hatch has a movable upright "M1" and a fixed upright "M2". Preferably, as shown in the appended figures, the device 1 is fixed to the movable upright "M1" and is configured to interact with a pin 100 fixed to the fixed upright "M2". The pin 100 can have a U shape or a C shape. In other words, the pin has at least two rods perpendicular to a third rod, so as to define a portion configured to interact directly with the device 1. The device 1 comprises a support
