Definitions

  • the present invention relates to a system for gripping a key.
  • a door may include a lock operating with a key.
  • a lock operating with a key For example, an aircraft and in particular a helicopter can comprise a door provided with a key lock. Keys used on aircraft are sometimes small in size.
  • an aircraft can evolve in various environments and can be subjected to high thermal amplitudes.
  • the same helicopter can evolve in an area undergoing temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.
  • temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.
  • the document DE 199 64 314 A1 describes a system provided with a box housing a key that can move longitudinally in translation.
  • a two-lever release system and an automatic deployment system are arranged laterally on either side of the key.
  • the object of the present invention is therefore to propose a gripping system facilitating the detection or even the maneuvering of a key of small dimensions, especially in cold weather and with mittens or the like.
  • the invention thus relates to a gripping system for a key.
  • This gripping system comprises a hollow shell which extends in a transverse direction between two lateral sides open to an external environment, said shell extending longitudinally in a longitudinal direction from a rear side to a front side, the side front being open to the outside environment, the gripping system comprising two supports partially disposed in said shell, said two supports respectively comprising two recesses forming a variable-geometry reception space configured to contain said key at least partially, said two supports being each movable in rotation relative to said shell to move closer to each other until reaching a blocking position in which said key is blocked, at least in translation in the longitudinal direction, and to move apart one from the other until reaching a displacement position in which said key is movable in translation in said direction longitudinally in said reception space, each support emerging laterally from the shell via a said lateral side and having a support portion arranged outside of said shell.
  • a key can be inserted into the gripping system.
  • the two supports are movable in order to block the key at least in translation relative to the shell or to allow the key to be moved relative to the shell on request.
  • the two supports can jointly form a clamp gripping the key in the locking position.
  • An operator can grasp the shell and can exert a force on the two support portions with mittens or the like.
  • the two supports move apart at the front side of the hull by means of two rotary movements according to opposite directions.
  • the supports loosen the key which allows the key to partially come out of the gripping system. However, the key remains partially retained in the hull without human intervention.
  • the operator can then relax his effort to immobilize the key with respect to the shell using the supports in order to introduce it into a lock. This process is reversible.
  • the gripping system proves to be relatively simple and can be used in various climatic conditions, and in particular in the presence of temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.
  • the gripping system actually has larger dimensions than the key. An operator can therefore more easily detect a key, and in particular a key inserted in a lock.
  • the gripping system can moreover have colors facilitating its visual detection. For example, the shell may be red in color.
  • the gripping system can be easily personalized.
  • the shell can be customizable.
  • the gripping system may include one or more of the following features.
  • the gripping system can perform other functions.
  • the gripping system can in fact comprise at least one interface arranged on the shell and which can be requested by an individual to activate various functions.
  • an interface can be in communication by usual means with other components of the aircraft, and for example with an engine preheating system.
  • the gripping system can comprise a lamp.
  • the gripping system can comprise a radio-identification system, usually known by the acronym “RFID” and the English expression “radio frequency identification”.
  • the gripping system can be produced with qualified aeronautical materials, in particular within the framework of an aeronautical application.
  • the hull and the supports can in particular be obtained with a material that can withstand the environmental conditions experienced by an aircraft, in particular conditions of resistance to fuel, ozone, ultraviolet rays, de-icing fluids, etc.
  • each recess may comprise a front notch receiving a head of said key in said locking position when said key crosses said front side in a deployed position, each recess comprising a rear notch receiving said head of said key in said locking position when said key is in a retracted position.
  • the recesses thus make it possible to immobilize the key with respect to the shell when the key is in a retracted position or in an extended position. In the deployed position, the key can be inserted into a lock.
  • said rear notch can be arranged between the rear side of the hull and said front notch.
  • Each rear notch keeps the key retracted in the shell.
  • said front notch and said rear notch of the same recess can be delimited, in a single direction of the transverse direction, respectively by two arcuate edges.
  • the recesses can thus cooperate by shape interference with a key having a gripping head in the form of a ring extended by an actuating portion. Only the actuating portion is configured to be engaged in a lock.
  • each support may comprise a partition and a lateral flank delimiting the recess of this support respectively only in one direction of an elevation direction and in one direction of said transverse direction, said reception space s extending along said direction in elevation of the partition of one support as far as the partition of the other support, said reception space extending along said transverse direction between the lateral flank of a support and the lateral flank of the other support, said reception space emerging in the longitudinal direction on the open front side of the shell.
  • delimiting the recess means that the two supports participate jointly in the delimitation of the reception space. By moving away from or approaching each other, the two supports thus modify the geometry of the reception space to either confer freedom of movement in translation restricted to the key with respect to the shell, or block the key relative to the shell at least in translation.
  • the shell may comprise a first wall and a second wall arranged one above the other in an elevation direction, said shell comprising an elevation wall connecting, in the elevation direction, the first wall to the second wall, said supports being arranged partially between the first wall and the second wall.
  • the shell has a U-shape in section in a plane orthogonal to the transverse direction.
  • This U-shape allows the key to partially come out of the shell from the front side and allows the brackets to come out of the shell from the side sides.
  • the gripping system can comprise an elastic pusher configured to grip said key and to exert on said key a force tending to cause an actuation portion of the key to come out of the shell via said front side.
  • elastic pusher means that at least one member of the pusher is elastically deformable, for example to be able to be compressed, or even stretched, with respect to a position at rest. For example, the pusher is in its rest position when the key is in its deployed position.
  • the pusher thus has two functions. It allows the key to be pushed into its deployed position, while retaining it so that this key does not completely come out of the shell. The key is partially retained in the reception area by the pusher.
  • This pusher also has the function of authorizing the movement of the key to its retracted position. For example, a member of the pusher is compressed when the key is in its retracted position, then stretches to return to its rest position by pushing the key into its deployed position.
  • said pusher may comprise a hook configured to penetrate a head of said key, said pusher having a spring which extends in said longitudinal direction between a seat of the shell and said hook.
  • Such a seat can be formed by the raised wall described above.
  • the pusher can thus tend to immobilize the key in rotation by shape interference with the head of the key.
  • the pusher and the notches can thus jointly immobilize the key with respect to the shell.
  • said hook may comprise a finger configured to penetrate into said head and a retaining face, said retaining face describing an arc of a circle centered on a first axis, the first axis being configured to be offset with respect to a second axis on which is centered an arc of a circle followed by an edge of said head.
  • the edge of the key is then attached to the retaining face.
  • said hook may include a guide channel, said spring extending in said guide channel.
  • said two supports can be rotatable relative to the shell around the same geometric axis of rotation.
  • At least one of said supports may comprise a pin which is arranged in a housing of said shell and is rotatable in said housing or at least one of said supports may comprise a housing mobile in rotation around a pawn of said hull.
  • each support is easily made mobile in rotation relative to the shell.
  • At least one of said supports can include a stop which is movable in a groove of said shell between two sides of the groove or at least one of said supports can include a groove in which a stop of said shell is mobile.
  • each support is rotatable relative to the shell within the limits imposed by a groove and an abutment.
  • each support can comprise a foot coming into abutment against a stop face of an elevated portion of the shell in the displacement position.
  • said support portion of a said support can be arranged in said longitudinal direction between said rear side and a geometric axis of rotation of this support.
  • said gripping system may comprise a return system for placing said two supports in the locking position in the absence of a force exerted on the supports by an operator greater than a force threshold .
  • such a return system is a magnetic system comprising one or more permanent magnets.
  • the return system comprises a sub-assembly called for convenience “closing reminder” and/or a sub-assembly called for convenience “rest reminder” per support configured to maintain this support in the blocking position until a force threshold exerted on this support.
  • the reminder system comprises two magnetic closure reminders respectively for the two supports, each closure reminder of a said support comprising a first closure member fixed to this support and a second closure member fixed to a wall of the shell attached to this support, at least one of the first closing member and second closing member comprising a permanent closing magnet.
