Abstract: A buckle having a device for gripping a length of webbing, comprising a buckle body formed from two side arms connected by an end arm. A locking device is connected to the ends of the side arms. A first transverse bar is mounted between the two side arms. A second transverse bar having a gripping surface is mounted between the first transverse bar and the end arm, and is vertically offset from the first transverse bar. A gripping cam is pivotally mounted between the two side arms and in between the transverse bars. The gripping cam has a gripping surface that contacts the second transverse bar and an opposite free end. A length of webbing threaded between the second transverse bar is securely held between the gripping surfaces of the transverse bar and gripping cam until the free end of the cam is pressed downward. If the cam breaks, the webbing is still held in place by the two transverse bars.

Abstract: A clamp assembly for detachably joining two adjacent portable stage modules. The clamp assembly is attached to the underside of one of the modules. When not in use, a spring biases the clamp away from the attachment bracket. The clamp includes two resilient, outwardly curving wing elements. Each wing element has a pair of opposing locking slots or engaging surfaces. A variable distance from a midpoint of a line segment between the two forward locking slots to the rear locking slots is the operational criterion for detachably joining two stage modules. When the wing elements are inwardly biased toward each other, thereby assuming a tension position, the distance between the midpoint and the rear locking slots is greater than when the wing elements are in a relaxed position.

Abstract: A side release buckle has a female member and a male member which includes a central post that is received in a channel of the female member and a pair of spaced somewhat parallel flexible engagement or latching arms having protuberances or heads that have crescent shaped latching shoulders. The arms flex inwardly as they enter an opening into a cavity of the female member and then outwardly when the heads are aligned with the side aperture at which the crescent shaped shoulders engage surfaces of the side walls of the female member adjacent these apertures. The crescent shaped shoulders supply increased bearing area capable of resisting more efficiently the linear and torsional loads normally encountered by side released buckles.

Abstract: The present invention is directed to a pinch resistant buckle assembly to reduce the potential for pinching the skin of a person when connecting a female receptacle and a male latch of the assembly. The male latch has an outwardly extending engagement portion which is received by a female receptacle. The female receptacle has a body having a chamber adapted to releasably engage the engagement portion of the male latch. The chamber has an opening at the engagement end of the female receptacle body through which the engagement portion of the latch passes to engage the chamber.A guide shield is located adjacent the opening and extends substantially away from the opening in a direction from which the male latch is inserted. Extending the shield outwardly away from the opening effectively enlarges the area of the opening by providing a larger effective area to guide the engagement portion of the male latch into the opening. The guide shield provides an extended surface leading into the chamber through the opening.

Abstract: A coupling assembly for connecting adjacent ends of conduits, primarily used for aircraft fuel, water and oxygen lines having redundant locking features is provided. This coupling can be manipulated with one hand and includes laterally spaced locking tines which engage a mating channel for locking the coupling in secured relationship. The coupling assembly can be manipulated with one hand and has viewing ports to ensure that all parts are in place. A pivotal locking member is provided to supply additional redundancy. The locking member has at least one fin which is received between the locking tines and snaps into locking position when the coupling is securely fastened. If the coupling is not securely fastened, the fin will not fit between the tines, thereby preventing the locking member from snapping into locked position. Thus, the mechanic will know that the coupling is not securely fastened and will take steps to remedy the problem.

A method of assembly is also disclosed.

Abstract: A side release buckle having an improved locking mechanism includes a male plug member and a female socket member. The plug member has a pair of resiliently flexible arm members. Each arm member includes a recess or notch disposed along the central longitudinal axis of the arm member which is adapted to engage a tooth arranged in a corresponding position in the socket member when the plug member is fully inserted into the socket member. Since the engagement or retaining force between the recess and the tooth lies along the central longitudinal axis of the arm members, this force directly opposes the load force on the buckle which acts to separate the two buckle pieces. Because of the proper positioning and arrangement of the recess and the tooth, the load force and the retaining force are aligned along the same axis, thereby providing increased holding power.

Abstract: An electronic musical instrument includes a pitch designation device for designating a pitch of a musical tone, and an operation device for setting an operation state of the electronic musical instrument and outputting operation data according to the operation state.

The musical tone parameters include musical tone parameters directly corresponding to the designated pitch, and musical tone parameters for resonance tones. The musical tones are generated according to these readout musical tone parameters. The electronic musical instrument can obtain a resonance effect, a change in tone color, and the like, which are approximate to those of an acoustic instrument.

Abstract: A heat dissipating assembly which is releasably secured in the assembled configuration by means of a spring clip. The spring clip being configured on one end thereof with a lever or rocker arm which permits its assembly or disassembly by hand without the use of any tools.
