The grommet is insertable into a penetration hole of a car body panel of an automobile. The inner sleeve includes a car body hooking hook that is arranged on an outer face of a peripheral wall. The inner sleeve is stored and fixed in an enlarged tubular portion and includes a peripheral wall having a bottom face. A grommet main body is made of an elastomer and includes the enlarged tubular portion located at one end of a small diameter tubular portion which is adapted to receive electric wires. A connector is fixable in the inner sleeve by locking and includes a terminal insertion face. The bottom face of the peripheral wall abuts on a bottom wall of the enlarged tubular portion. A large space is provided between the terminal insertion face of the connector and the bottom wall of the enlarged tubular portion.

Abstract: The invention is one to provide a part mounting bolt, which is favorable in work efficiency since a latch member mounted on a pivot section does not fall off and there is no need of fitting the latch member onto the pivot section manually, in which a gear of resin is insert molded on an upper region of an external thread of a metallic bolt body to rotate a bolt about an axis, the part mounting bolt comprising a pivot section formed integrally on one end of the bolt body and made of the same material as that of the bolt body, and a latch member of resin integrally insert molded on the pivot section to fix a part on a mounted member.

Abstract: Adjustable length element includes a first member having threads and a second member having threads. The adjustable length member also includes at least one protrusion on one of the first member and the second member, with the at least one protrusion being capable of engaging and disengaging at least one stop associated with the threads of the other of the first member and the second member as the first member and the second member are rotated relative to each other. A lancet device includes a housing, a needle holding member in the housing for holding a lancet, a biasing element for biasing the needle holding member toward an extended position, and a trigger for releasing the needle holding member from a retracted position. The lancet device also includes a cap for covering the housing and for positioning the lancet device relative to a skin surface, the cap including a first cap member having threads and a second cap member having threads.

Abstract: A two member threaded fastener includes integral ribs and/or locking fingers formed concentrically around threaded portions of the two members which make up each fastener. The ribs and/or locking fingers interferingly interengage one another as the two members are threadedly intermated to either removably or permanently lock the members together as desired for a given application. Preferably, the locking fastener members are formed of a polymeric resin and include concentric annular rings which are spaced from the threaded portions of the fastener members by interconnecting webs and define axially extending ribs. The ribs are rounded and preferably sinusoidal for removably locking fastener members and are serrated for permanently locking fastener members.

Abstract: A safety device for bicycles, for preventing unscrewing, comprises a ring element which can be mounted coaxially on the outer ring of the upper steering bearing and on the lock nut to lock them in position on the tubular sleeve of the fork mounted rotatably in the steering tube of the frame. The ring element is clamped onto the ring of the bearing and the lock nut so as to prevent the accidental unscrewing of the lock nut. It also has a radial appendage which is adapted to act as an abutment for the end of the sheath of a flexible brake-operating cable.

Abstract: A tensioning assembly for applying tension to a band-type clamp includes a T-bolt having a shank portion and a T-head portion. The T-bolt is adjustably mounted to a first end of the band clamp and a keeper constructed and arranged to receive the T-head portion of the T-bolt is affixed to a second end of the band clamp. A nut threadably engages the shank portion of the T-bolt and rotation of the nut on the T-bolt draws the head to the T-bolt towards the first end of the band clamp thereby drawing with it the second end of the band clamp. An anti-rotation device is associated with the nut operably engageable with the nut to prevent its rotation. The anti-rotation device cooperates with a force-applying tool, such as a wrench, so that when the tool is placed on the nut, the anti-rotation device disengages from the nut. Preferably the tensioning assembly also includes an indicator remote from the T-bolt and operably associated with it to indicate the achievement by the T-bolt of a predetermined tension.

Abstract: A bearing lockout assembly having a locking cup piece which maintains locking keys in retentive association in counterbores of a lockout is disclosed. The locking cup piece is keyed on its inner diameter to a shaft and provided on the edge of its outer diameter with means to coact with the locking keys to define a vernier self locking feature.

Abstract: An orthodontic screw-type biassing device comprises: a first member having an internally threaded bore, the threaded bore comprising first and second threaded portions adjacent each other in the axial direction of the bore, the first and second threaded portions having thread roots which lie substantially on a common line, the first threaded portion having threads of given depth and the second threaded portion having threads of a lesser depth. A threaded inner screw-type member is threadably engaged in the internally threaded bore of the member, the threads at an end portion of the inner screw member being deformed so as to freely, threadably pass through the second threaded portion of the threaded bore and to bind and be non-rotatable in the first threaded portion of said threaded bore. The invention is also directed to a method of making such a biassing device.

Abstract: The push frame (12) of a tractor-scraper (10) normally has a plurality of cover plates (14) relasably secured therebelow to provide access internally of the push frame. In standard practice, the cover plates are secured to the push frame by a plurality of bolts and the heads of the bolts are subjected to wear and possible breaking-off due to their exposure upon operation of the tractor-scraper. This invention provides a mounting assembly (13) for expeditiously removing and replacing the cover plates upon wearing or breaking-off of the heads (19) of bolts (18) thereof by providing an internally and externally threaded bushing (24) which is threadably connected on the push frame and is further threadably connected to each bolt. Thus, a workman need only engage the bushing with a socket wrench or the like to release the bolt and thus the cover plate upon wearing or breaking-off of the heads of the bolts.

Abstract: A safety bolt having a headed end, a shank, and a second end with means near the second end to hold the bolt in a hole in a workpiece. An axial passage opening into the second end intersects a laterally-extending passage spaced therefrom, and a dog fits in the laterally-extending passage wherein it is laterally reciprocable so as to be extendible beyond the maximum diameter of the shank or to be entirely retracted within it. A cam member having a pair of oppositely facing cam surfaces is axially slidable in the axial passage. The dog has a pair of followers one on each side bearing against oppositely directed cam surfaces whereby the lateral position of the cam is uniquely a function of the axial position of the cam member. Bias means is provided to bias the cam member to a position corresponding to maximum extension of the dog.

A bias spring is provided to bias the cam member to a position corresponding to maximum extension of the dog. A plug is detachably attachable to the safety bolt to hold the cam member in a position respective to retraction of the dog. A projection can be provided on a nut for use with this bolt to prevent reversal of the nut, and a plurality of bias springs each with a different rate can be used.

Abstract: An electrical connector assembly that is readily coupled or uncoupled is provided with means for retarding premature uncoupling thereof. The connector assembly comprises a first shell 100 having a flange 140 thereabout and bosses 111 on the periphery thereof adjacent the flange, and a coupling nut 300 that has stop members 311 on the inner wall thereof. A spring 500 is situate between the flange 140 of the first shell 100 and the end wall 305 of the coupling nut, with the stop members preventing rotational movement of the spring 500 relative to the coupling nut 300, while the bosses 111 retard movement of the spring 500 relative to the first shell 100.
