International Classification:

A44B 1700

US Classification:

24295, 24289, 24293, 24458, 24517, 411508

Abstract:

This invention relates to a spring fastener, which comprises engagement springs in opposite sides of the fastener. Each engagement spring has an engagement region comprising a hindrance portion, which increases considerably the removal to insertion force ratio as compared to such ratio in the absence of the hindrance portion, thus permitting very easy insertion with considerably more difficult removal of the fastener from the slot of a panel, which provides an efficient ergonomically balanced removal to insertion force ratio. The hindrance portion comprises ripples or other hindrance elements of unexpectedly minute dimensions for providing this efficient ergonomic force balance.

US Classification:

24295, 24289, 24293, 24458, 411508

Abstract:

A spring fastener, which comprises two engagement springs in opposite sides of the fastener. Each engagement spring has an engagement portion comprising a hindrance portion, which increases considerably the removal to insertion force ratio as compared to such ratio when the engagement portion does not have the hindrance portion, thus permitting very easy insertion into, with considerably more difficult removal of the fastener from the slot of a panel.

F16B 5/12

US Classification:

24293, 24294, 24295

Abstract:

A fastener comprises two engagement springs on opposite sides of the fastener. Each engagement spring has an elongated rib. The elongated ribs may have a substantially rectangular shape, or any suitable shape, and they may protrude away from the opposite side of the fastener. Additionally, the elongated ribs may have same or different slopes at each end of the ribs. According to one embodiment, the elongated rib increases the removal to insertion force ratio as compared to such ratio when the engagement springs do not have the elongated rib.

International Classification:

B25B 27/14

US Classification:

29816

Abstract:

A tool for securing items together closes C-rings to create hog rings. A drive mechanism allows the tool be used continuously for a greater length of time than heretofore possible without inserting a new string of C-rings. The drive mechanism utilizes one-way clutch bearings to provide a ratchet-like mechanism. Each time a trigger on the tool is pulled, a C-ring is closed and another C-ring is advanced to a position in which it may be closed by the same jaws. A pneumatic system moves a piston inside a cylinder to move the C-rings along a magazine towards the jaws.
