In order to avoid the danger of locking the projection at its insertion into the slot, and to assure that the end portions retain their required relative position when applying tension to the clamp, the projection is a circumferentially extending bar and the slot has a pair of flaps on opposite edges of the slot and protruding into the slot. The bar has notches which are provided for the radial passing of the flaps and the bar is shorter than the slot of the clamp in a circumferential direction.Type: GrantFiled: November 2, 1993Date of Patent: October 11, 1994Assignee: Rasmussen GmbHInventor: Ralf Spors

Patent number: 5307541Abstract: The present invention relates to a clamping device for semipermanently fixing a part, such as a fluid conveying hose, dustproof bellows, axial boot or the like, on the circumferential surface of an desired mating device. According to this invention, even if such part looses its elasticity owing to aging, the clamping device maintains the permanent stable firm clamping state. For this purpose, the inner and outer overlap portions (11a, 110a; 11b, 110b) of the clamp band (11, 110) made of metal strip material (M) are forced by an operating tool to close until the seizing tooth (16a, 160a) of the inner overlap portion (11a, 110a) and the fixed tooth (22b, 220b) of the outer overlap portion (11b, 110b) seize each other, thereby contracting the bore diameter of the clamp band (11, 110).Type: GrantFiled: July 15, 1993Date of Patent: May 3, 1994Assignee: Kobushiki Kaisha KenlockInventor: Kenji Nagano

Patent number: 5247723Abstract: In U-shaped closing stables for bags and flexible tubes, which staples are made of strip material and consist of a crosspiece (7) and two legs (4) and in which the leg ends of the staple have been bent off outwardly to constitute a connecting web (2), by which the staple is severably included in a train (1), the severing of each staple from the train (1) will result at the severing location in the formation of burrs, which protrude beyond the strip width of the staple and may result in damage to the closed wrapper and to other wrappers. In order to avoid that, the width of the strip adjacent to the leg ends (6) over a portion (3) of the legs (4) and over the connecting web (2) is reduced approximately parallel on both sides so that the leg ends (6) which have been bent off outwardly uniformly engage the legs (4) on the outside within the width of the strip and there is no burr protruding beyond the width of the strip. An apparatus for closing such staples is also provided.Type: GrantFiled: June 21, 1991Date of Patent: September 28, 1993Inventor: Herbert Niedecker
