Publication number: 20080168627Abstract: A positioning sleeve includes first and second surrounding portions adapted to surround outer and inner tube sections of a telescopic rod, respectively. The second surrounding portion has a plurality of angularly spaced-apart recessed parts and a plurality of compressible retaining units respectively disposed in the recessed parts. Each retaining unit is connected to the corresponding recessed part, and has an engaging part projecting toward a through hole in the second surrounding portion, and a deformable space defined between the engaging part and the respective recessed part. The deformable space is deformed when the inner tube section is friction-fitted into the second surrounding portion and when the engaging part of each retaining unit abuts the inner tube section.Type: ApplicationFiled: January 16, 2007Publication date: July 17, 2008Inventor: Hsin-Yuan Lai

Patent number: 6398466Abstract: A chuck 30 is formed with a generally cylindrical body 54 formed with a bore 60 at a forward end 58 thereof. A fixed clamp segment 134 and a movable clamp segment 166 are located in radial opposition in the bore 60. A pair of ribs 142 are formed on the fixed segment 134 and extend radially inward. A single rib 172 is formed on the movable segment 166 and extends radially inward. The ribs 142 and 172 cooperate to clamp a shank 42 therebetween in a clamping mode. A sleeve 78 is positioned about the body and is movable axially relative thereto. A camming section 88 formed on an interior wall of the sleeve 78 is captured between a head 124 of a pin 122 and a detent ring 132 to latch the sleeve in an unclamped mode. When the shank 42 is inserted into the bore 60, the forward end of the shank engages the pin 122 to move the head 124 against the camming section 88 which, in turn, moves the section past the detent ring.Type: GrantFiled: July 21, 2000Date of Patent: June 4, 2002Assignee: Black & Decker Inc.Inventor: Dale K.

Patent number: 5105148Abstract: An electrical test probe with replaceable tip is provided, which is of low cost and high durability. The probe includes a body (16, FIG. 5) having a chuck-holding recess (26) in its front, with the walls of the recess forming a shoulder at the front and forming an external thread. A probe-holding chuck (52) has a rear portion lying in the body recess; a nut (14) surrounds the front of the chuck and is threadably connected to the body. The chuck is split along an imaginary plane (70) extending at an angle of about 45.degree. from the axis of the probe, into front and rear chuck parts (64, 66). As the nut is tightened to press against the front end of the chuck, the front chuck part (64) slides sidewardly along the split plane so the probe tip (12) is trapped by shear forces between the forward and rearward chuck parts (64, 66).Type: GrantFiled: January 24, 1991Date of Patent: April 14, 1992Assignee: ITT CorporationInventor: Jerry L.

Patent number: 4881683Abstract: A knockdown bulk container for storing and shipping bulk quantities of fluid and semi-fluid substances including an annular base, an annular cap and a circular side wall. The side wall is formed of a number of paperboard slats adhered to a sheet of paperboard. The side wall is adapted to be folded into a substantially flat condition for shipping and storing and formed into a cylinder which is inserted in the annular base for filling of the container. The dimensions of the base and cap are such that the cap and base are nestable. The bulk container provides substantial economies in space saving.Type: GrantFiled: January 27, 1988Date of Patent: November 21, 1989Assignee: Shippers Paper Products CompanyInventor: Kent A.
