Abstract: A latch comprises a support block which, in use, is attached to a first member, and a strike block which, in use, is attached to a second member. A first lever is attached to the support block and shaped to engage with the strike block when the first and second members come into contact. A link member is pivotally attached to the support block. A second lever is pivotally attached to the link member and is shaped to engage with the strike block, with a third lever, pivotally attached to the link member and engageable with the support block, to retain the latch in a latched position. Biasing means biases the third lever into engagement with the support block when the second lever is in its engaged position.

Abstract: A one-part, front mounted receptacle 1 for a quick release fastener has a first element 11 which provides a retention mechanism 12 for engaging and retaining a stud of the fastener. A second element 16 having a pair of flexible elongate components 17 is spaced from the first by a bight portion 14 and has a pair of transverse tabs 19 disposed adjacent the bight portion. These are adapted to engage one face 33 of a support 30, in an aperture 31 of which the receptacle is mounted. In use, the bight portion 14 engages the other face 32. A third element 20 is disposed at the opposite end of the second element 16 from the bight portion 14 and has a flexible barb portion 23 arranged to flex on insertion of the receptacle in the aperture and to engage the other face after insertion in order to retain the receptacle in the aperture.

Abstract: A fasting device has a shaft and a clamping assembling. The clamping assembly has an outer housing shaped so as to retain the object to be clamped in position and an inner core rotatably disposed within the outer housing and in threaded engagement with a hole in one of the outer housing. A sprag is disposed within the outer housing and located in a slot in the inner core, both the inner core and the sprag plate having through holes to receive the shaft. A bias spring biases the sprag into engagement with the inner core.

Abstract: Disclosed is a lever mechanism for clamping a board to a housing. A support block is provided and is adapted to be attached to the board. A first lever, pivotally connected to the support block, is movable between first and second positions, and adapted to engage with the housing when in the first position and disengage from the housing when in the second position. A second lever is pivotally mounted on the first lever and adapted to hold the first lever in the first position by engagement with the support block. A spring is also provided for biasing the first lever towards the second position and also for biasing the second lever toward the position in which it engages with the support block.
