Definitions

  • the invention is an improved ratcheting pawl latch having an improved pivot for its paddle.
  • Latches are commonly used to secure a moving panel to a stationary panel, and it comes as no surprise that several other latches have been proposed by various inventors. However, the present inventor is unaware of any other latch having a handle being pivotally secured at each end with a gooseneck-shaped member, thereby providing the user with the leverage and ease of use provided by the present invention.
  • the present invention relates to a latching system for securing two panels together such as those of storage structures in which an enclosure is secured by means of a door or panel which will remain in a closed position until released

  • the actuating lever can be provided in the form of a handle or paddle
  • the sp ⁇ ng locking member enables a force from a handle of the latch assembly to be transmitted to a pawl which selectively engages and disengages a keeper member When the keeper member engages the pawl, the pawl is rotated until the locking member slips in behind it
  • the pawl is provided with a torsional sp ⁇ ng member which causes a force load from the sp ⁇ ng member to be supplied to the pawl
  • the paddle is pivotally secured to a surrounding paddle surface, with a pair of gooseneck-shaped members extending from either side of the paddle to the pivots When the paddle is pivoted away from the panel surface to which it is attached, the sp ⁇ ng locking member is engaged
  • the present invention also provides a locking mechanism in which a key can selectively lock and unlock the latch assembly It is a p ⁇ ncipal object of the present invention to provide a novel latch assembly which is selectively engagable with a keeper member, and includes a spring locking member which is spring-loaded with its own spring force for engaging and releasing a pawl from a keeper member when a handle is actuated
  • Another object of the present invention is to provide a lock which can be operated by a key or other operator, such as radio, infrared, electronic or other means, which selectively engages the locking member against movement

  • the pawl 36 has a locking arm 40 and is provided with a pawl slot 42 to retain a keeper member
  • the keeper member is attached to the stationary panel or compartment (not shown) at a position such that when the swinging panel to which the latch assembly 10 is attached is rotated to engage the keeper member, the keeper member will be below the arm portion of the upper flange 44 for engagement with the pawl 36
  • the pawl 36 is also shown having an arm portion 46 extending from the pawl 36
  • a pawl torsional sp ⁇ ng 48 is shown installed on the pawl 36, having a pair of coil portions 50, a pair of ho ⁇ zontally extending tail portions 52, and a pair of arms 54 connected together at their ends to form a slot 56 for receiving the pawl arm 46 therein for engagement therewith
  • the pawl sp ⁇ ng 48 biases the pawl towards its unlatched position
  • a notched portion 66 is shown in the back of the pawl 36 to provide clearance for the locking member 60, when the pawl 36 is released (desc ⁇ bed later) This facilitates the relief of stress upon the s

  • One preferred retaining portion 62 is dimensioned and configured to snap into a recess 63 on the housing 14, with a suggested shape for the retaining portion 62 being rectangular
  • An alternative sp ⁇ ng retaining portion is in the form of a flat rectangle, being dimensioned and configured to slide into a slot in the housing (not shown, but desc ⁇ bed in U S Pat No 5,927,772, the complete disclosures of which are incorporated herein by reference)
  • the sp ⁇ ng locking member 60 is preferably comprised of a sp ⁇ ng steel composition or plastic composition such as for example acetal, or any suitable like flexible member which is also durable enough to withstand the forces of actuation of the latch assembly
  • Suitable mounting means are provided to retain the latch assembly 10 on a panel or mounting surface, such as those illustrated in FIGS 9-10
  • installation of the latch assembly 10 to a panel 72 may be accomplished with the mounting means shown in Fig 2 comprising apertures 68 and bolts or screws 70
  • the panel 72 may be plastic so that when the screws 70 are secured in the apertures 68, the process of turning the screws in the aperture creates corresponding threads within the aperture 70
  • An example of a panel 72 where such a latch 10 would be useful is a glove box of an automobile.
  • the latch 10 works in conjunction with a keeper installed on the stationary panel.
  • the keeper is secured within the latch 10 when the latch 10 is in the closed position.
  • the keeper member may comprise a striker wire or any like suitable member such as a bar, claw, or other suitable attachment member.
  • the usual rest position of the latch will be the closed position illustrated in FIGS. 4-5, with the pawl 36 in its latched position, and the keeper trapped within the pawl slot 42 and between the pawl-locking arm 40 and the upper flange 44.
  • the pawl 36 is biased towards its unlatched position by the spring 58, but is abutted by the locking member 60, thereby securing the pawl 36 in the latched position.
  • the latch assembly 10 is actuated by lifting the paddle 12 in an upward direction (away from the surface to which the latch assembly 10 is mounted).

  • the pawl-engaging portion 64 of the locking member 60 thereby moves out of engagement with the pawl locking arm 40 thereby freeing up the pawl 36 for pivoting.
  • the bias provided by the pawl torsional spring 48 releases the pawl 36 from its vertical position and allows the pawl 36 to rotate to its unlatched position to disengage the keeper member, thereby opening the compartment or panel to which the latch assembly 10 is attached.
  • the open position of the latch is illustrated in FIGS. 1-3.
  • the keeper strikes the pawl's arm 46, thereby rotating the pawl so that the locking arm 40 traps the keeper between itself and the upper flange 44, within the pawl slot 42.
  • the rotation of the pawl will also cause the notched portion 66 of the pawl to strike the pawl engaging portion 64 of the spring locking member 60, thereby pushing the spring locking member 60 downward and out of the path of the pawl.
  • An important advantage of the present invention over other latches is the ease with which a user may grasp the paddle 12, and use the paddle to open the panel 72.
  • the finger recess 78 allows a user to insert their fingers fully behind the paddle 12 for maximum leverage.
  • the gooseneck-shaped mounting flanges 22 of the paddle 12 allow the paddle 12 to move away from the panel 74 as the latch is actuated, thereby allowing additional room for a user's fingers and providing maximum leverage for the user to open the panel 72.
  • the latch 10 may include a lock, preferably key-operated, for locking the latch in the closed position.
  • a lock preferably key-operated
  • the structure and function of the lock is fully described in U.S. Pat. App. No. 09/299,246, and U.S. Pat. No. 5,927,772 The full disclosure of both is incorporated by reference.

Abstract

Cette invention concerne un loquet (10) permettant de verrouiller un panneau mobile sur un panneau fixe. Ce loquet est commandé par une poignée (12) montée pivotant sur le boîtier par une paire de bras en col de cygne (22). En pivotant vers l'extérieur, la poignée (22) appuie sur un élément de verrouillage à ressort (60), ce qui fait passer un cliquet (36) sous charge de ressort d'une position de verrouillage à une position de déverrouillage. Lorsque le panneau mobile se ferme, une clavette vient heurter le cliquet (36) et le fait tourner sur la position de verrouillage. En pivotant, le cliquet (36) écarte l'élément de verrouillage à ressort (60), lequel revient à sa position de départ et bloque le cliquet en position de verrouillage. Le boîtier comprend un évidement concave pour les doigts (78) qui donne accès au loquet (10). Il est fixé sur le panneau au moyen de vis autotaraudeuses (70). L'action combinée des bras en col de cygne (22) et de l'évidement pour les doigts (78) permet d'engager complètement les doigts derrière la palette (12) et d'exercer un effet de levier maximum pour l'actionnement du loquet et le déplacement du panneau immobilisé.
