The releasable connection comprises: a forwardly open inner sleeve 2 which is formed on the handle 1 and has diametrically opposite axial slots 11, 12; an outer sleeve 3, mounted rotatably but axially non-displaceably on the inner sleeve 2; and a pin 5, 6 which is inserted in the inner sleeve 2 and is divided into two in the axial direction. The outer sleeve 3 has an internal screwthreading 16, 17 recessed by axial grooves 18, 19 at two diametrically opposite places. By the rotation of the outer sleeve 3 in relation to the inner sleeve 2, the grooves 18, 19 can be brought into alignment with the slots 11, 12.

  • Patent number: 5000467
    Abstract: A trash can transporting apparatus and method of use having a spring-loaded hook assembly and an upper support bracket, each adjustably secured to a main shaft by a level adjustment lock, the hook assembly including a spring-loaded hook having an upward facing plurality of fingers for grasping a reinforced peripheral rim of a trash can container seated on a stabilizing basket connected to the main shaft while a trash can closure lid is intact, the combination improving the stability and the transporting efficiency of the apparatus. The hook assembly and upper support bracket are adjustable along the vertical dimension of the main shaft for accommodating various sized household plastic trash can containers. When not in use, the apparatus can be displayed, shipped, stored, or transported by disassembling the various components including the main shaft, each comprised of a high-strength plastic.

  • Patent number: 4884914
    Abstract: A support device for supporting a longitudinal member, such as a threaded rod, in a desired position with respect to the support device includes a housing adapted to receive the threaded rod, transversely within a housing aperture, and a slide axle, slideably received axially within the housing. The slide axle receives the threaded rod and is slidable within the housing to (1) a first position frictionally engaging the rod and (2) a second position disengaged from the rod so that the rod can be relatively freely moved with respect to the slide axle. The rod supporting device includes a tightening member or lock nut to secure the slide axle in a locked position whereby the rod is tightly held against a housing bearing wall defining a portion of the housing aperture. The housing bearing wall is relatively smooth so that the threaded rod is tightly held in locked position by the lock nut, while minimizing axial movement of the rod with respect to the housing.

  • Patent number: 4881765
    Abstract: The vertical slide in the latch linkage of an exit device is coupled for vertical movement together with a channel inside the door stile. The channel holds a pair of blocks having inclined surfaces held in touching relation and relatively slideable. The vertical latch-operating rod is attached to the first of the blocks and the other block is secured to the channel by a horizontally disposed threaded adjusting element. The side walls of the channel restrict the first of the blocks from lateral but not vertical movement. The other block is restricted from lateral movement only by the threaded element, and turning the threaded element moves that block from side to side in the channel to raise or lower the first block as the inclined surfaces slide. This changes the effective length of the rod. The turning of the threaded element may be done from the outside of the door through an access hole.

  • Patent number: 4863326
    Abstract: A captive fastener for securing two closure members together comprises a crew component adapted to be affixed to one of the closure members and a complimentary nut component adapted to be affixed to the other closure member. The screw component comprises a housing, a drive sleeve disposed within the housing for rotational movement therein, and a screw member in operatinal engagement with the drive sleeve whereby the screw member is axially movable between extended and retracted positions relative to the housing in response to the rotational movement of the drive sleeve. The nut component comprises a shell, a nut member disposed within the shell for limited axial and radial movement therein and fixed against rotation, and biasing means for urging against the axial movement of the nut member. The radial and axial movement of the nut member facilitates the alignment and engagement of the screw member with the nut member to eliminate binding when the closure members are assembled.

  • Patent number: 4793611
    Abstract: Portable, lightweight-construction toy basketball set made of releasably interlocking plastic parts for ease of assembly and disassembly in which backboard structure and a base support are interconnected by an elongated upright standard. An elongated upright is provided which is divisible into separate columns which interfit telescopically and present helically-oriented interrupted threads for ease of selection of upright height and release for further adjustment or separation of the columns. A bracket interconnects a hoop flange to the backboard with the bracket and hoop flange having matching interfitting configurations for yieldably releasing the hoop for angular relative movement with respect to such backboard so as to prevent damage to interfitted parts during execution of a slam dunk play and to permit angular relative movement for manually returning such hoop to normal play position.
