Convolutions Of Coil Form Faces Patents (Class 24/550)
  • Publication number: 20090260200
    Abstract: The present invention is directed toward a bead securement device comprising a tension spring, a first cover and a second cover. The first cover and the second cover are removably secured to the tension spring. In use, a force is exerted on the spring through the covers causing the spring to deform and the gaps between the plurality of coils on the spring expand. Once expanded, the filament may be passed in between one of these gaps so that when the force exerted on the end members of the spring is released, the filament is squeezed between the coils of the spring and held in place. The filament can be easily removed by using the covers to manipulate the end members of the spring.

  • Patent number: 7350756
    Abstract: A fastener for the suspension of a birdcage toy or the like has a first end terminating in a first loop, and a second end terminating in a second loop, each of the first and second loops terminating in a free end that allows for easy attachment of objects to the loops. An additional section is defined between the loop free ends to assist in preventing the free ends from deflecting outward, resulting in possible inadvertent detachment from the cage or retained object.

  • Patent number: 7152837
    Abstract: A hanger apparatus is fabricated of a strand of material that is formed into a plurality of coils of incrementally decreasing diameter to fabricate a tapered, hollow helix. A hook or other engagement means is integrally formed at one end of the helix. The helix is compressively or frictionally engaged with an opening in a selected substrate to provide a hanger assembly for receiving and holding a selected object.

  • Patent number: 7051414
    Abstract: The method of easily and securely retaining components strung on a bead line by placing a portion of the bead line between coil members of a tension spring comprises applying torque action to leverable members of the tension coil between the thumb and index finger of the user's hand to spread apart contiguous coil members of the spring, placing a portion of the bead line between a pair of coil members which had been spread apart, releasing the torque action from the leverable members, and allowing coil members to close and securely maintain the portion of bead line in position on the coil spring in a manner to resist removal therefrom.

  • Patent number: 4569105
    Abstract: A compact collar for securing weights to a barbell. The collar utilizes a spring coil, restrained against maximum tightening, thereby setting a minimum internal diameter of the coil. A pair of outwardly extending angularly displaced arms that can be moved towards each other to reduce the tightness of the coil, thereby increasing the internal diameter of the coil and permitting it to slip over the end of a barbell. Once in place, the release of the arms, allows the natural spring tendency to tighten the coil and grip the barbell, thus holding the weights in place.

  • Patent number: 4457709
    Abstract: The holding device of the present invention comprises an elongated wire rod of unitary construction having a lower straight section with a pointed end adapted for insertion into an impression material of a dental mold, an intermediate section having a wire coil adapted to grip a dowel pin and an upper section extending from the intermediate section and being angularly displaced therefrom such that upon compressing and releasing the upper section relative to the intermediate section the turns of the wire coil are spread open for inserting and releasably locking a dowel pin therein with the dowel pin being automatically aligned relative to said lower section.
