Abstract: A roller bouncer and wave board skate (10) comprising a base plate (12). A plurality of wheel assemblies (14) are disposed on bottom of the base plate (12). A top plate (16) is provided. A structure (18) is for biasing the top plate (16) over the base plate (12). A foot plate (20) supports a shoe (22) of a skater (24). An assemblage (26) is for attaching the foot plate (20) to the top plate (16) in a removable manner, so that the skater (24) will bounce while skating.

Abstract: The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure (4), a wheel chassis (10), a wheel support (52), at least two wheels (50), and mechanisms which position the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The positioning mechanisms include tie rods (18), yokes (84, 86), gear sets (106), and externally mounted rods or panels (116). A post (30) on the bottom of the enclosure may include a threaded portion which is engaged by a nut (36) to rotationally secure the position of the wheel chassis, or the post may include a portion (94) of enlarged diameter supporting a spring (104) which biases the wheel chassis into the post. A brake (122) is provided to allow the user to slow or stop the skate in a controlled manner.

Abstract: At least one walking member is adaptively coupled to an in-line skate to enable the walking member to be extended and retracted to and from the skate, thereby enabling the in-line skate to be converted from a rolling skate to a walking shoe. Two walking members can be provided on alternative sides of the in-line skate wheels to provide a more stable platform for the wearer of the in-line skate. The walking members do not detract from the aerodynamic and functional performance of the in-line skate, and can be manufactured together with the skate or, alternatively, can be added to the skate after purchase.

Abstract: An in-line roller skate for use by children has a stability enhancing mechanism and a movement limiting mechanism. The stability enhancing mechanism includes two rollers, mounted on an axle, that are selectively positionable side-by-side in a normal mode or spaced apart in a stable mode. A combine arm having two fingers pivots downward to cam the rollers inward from the stable to the normal mode. Alternately, a separator arm pivots downward to slide the two rollers apart on the axle from the normal mode to the stable mode. The movement limiting mechanism includes a roller, mounted on an axle, that has teeth formed on the radially inner surface of the cylindrical outer portion. A pawl has a pawl arm extending into the inner cylindrical portion of the roller to engage the teeth and a pawl tongue that extends into a pawl adjuster.

Abstract: A non-explosive pyrotechnic linear release device is comprised of a body within which, at a proximal end, a pyrotechnic, comprised of a compressed gasless ignition powder, is contained behind a support ram which extends forward from the distal end of the body to support the sealed exit end of a pressure container which has been charged with a fluid, preferably air. The compressed pyrotechnic provides a psi pressure against the proximal end of the support ram greater than the psi pressure of the fluid against the sealed exit end of the pressure container. When the pyrotechnic is ignited by signal from an impact detecting element in the automobile during a crash, the pressure provided by the compacted pyrotechnic is dissipated, the support ram is then pushed proximally by the pressure from the pressure container and the exit end of the pressure container becomes unsealed and releases the fluid under pressure to the air bag or bags provided in the automobile.

Abstract: A multi-line in-line roller skate, having a frame (15) which includes a pair of siderails (4), a center rail (3), and a topsurface (5), the frame composed of two adjacent siderails separated by either one or two center rails all of which are communicating with the topsurface through a common connection of their top edges. The siderails and center rail(s) are positioned so as to form two parallel channels or planes in which a plurality of wheels may supportably rotate therein. This combination of frame and wheels along with axles, bearings, aperture plugs, and an assortment of many other accessories can be put together and attached to a boot/shoe (6) to form the multi-line in-line roller skate (14). The frame (15) is made of a light-weight sturdy material which can withstand the random degrees of pressure that may be exerted upon it, and the design of the frame allows for many adjustments and varied wheel configurations . The frame may take many forms to facilitate utilization.

Abstract: The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure, a wheel chassis, a wheel support, at least two wheels, and a tie rod which anchors the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The foot enclosure includes posts which support and secure the wheel chassis, with a nut threadably engaging the post to rotatably secure the wheel chassis relative to the foot enclosure. The tie rods have a predetermined length which maintains the angular position of the wheels relative to the foot enclosure regardless of the angular position of the wheel chassis.
