Abstract: PURPOSE: To easily manufacture a sleeve for an anchor bolt by forming a cylindrical collar having segments extending radially outwards, and bending the segments until they come to a position where they form a cylinder. CONSTITUTION: A blank 2 comprising a cylindrical collar 4 having a number of segments 8 extending radially outwards is formed. The blank 2 is a simple split type and is easily formed by casting, press forming, or forging. The segment 8 is bent around the shaft of the collar 4 unit it comes to an assembly position with a cylindrical shape and becomes a sleeve of an anchor bolt. The sleeve is inserted into a bolt with a multi-head and a nut is fixed. Then the head is introduced into the sleeve and the segments are expanded. The anchor bolt is inserted into a hole which is to be fixed and the nut is tightened, then the segments 8 are fixed to the hole and the anchor bolt becomes a strong one.

Abstract: PURPOSE: To provide a female clinch fastener adapted to be secured to a sheet by cold-forming. CONSTITUTION: This female clinch fastener 20 includes a generally tubular main body having a plurality of circumferentially spaced splines 35. Longitudinally extending portions of the splines 35 are adapted to be deformed by cold- forming, i.e., peeling, to form a laterally extending flange 33 along a medial portion of the tubular main body. The clinch fastener 20 includes a laterally extending second flange at one end which cooperates with the cold-formed flange 33 to secure the fastener within a pilot, i.e., a collar, formed at an opening in a sheet. The splines 35 adjacent to the end flange are secured within the pilot in the sheet and prevent rotation of the clinch fastener 20.

Abstract: PURPOSE: To provide a clip for connecting a rigid hydraulic pipe and a flexible hydraulic pipe by butting the end and the end. CONSTITUTION: A clamp part 12 extends in an almost circular shape from a base part 4, and has two locking members 28, 30. The first locking member 28 has an outward extending finger-like piece lever 32 and an inward turning fastening part 34, and the second member 30 has an outward extending finger- like piece lever 36 and an outward turning fastening part 38. One end part of a rigid hydraulic pipe is pushed in a circular part 18, and then, a socket member is pushed in a stud welded to a workpiece so that a clip is fixed to a prescribed position. An end part of a flexible pipe is inserted into the clamp part 12 to be pushed in a hexagonal part 18. The hexagonal part engages with the end part of the pipe to hold this end part in a state of tightly abutting on the rigid pipe so as not to make torsional motion.

Abstract: PURPOSE: To increase retention force by forming a head with a tapered stem at one end and arranging a tubular sleeve and a threaded retaining member at an area to the head and providing ratchet teeth. CONSTITUTION: A sleeve anchor is formed by a tapered stem 5, a tubular sleeve 6, and a retaining member 7, and the stem 5 is tapered toward a fixed diameter part from a head 8. Then, a retaining flat part 12 is formed at an end part 11 of the stem 5, and a hexagonal nut 3 with ratchet teeth 14 is mounted to an inner surface 15 of the retaining member 7. Further, ratchet teeth 16 is provided at one end of the tubular sleeve 6, three protrusions 17 are provided at the other end and one portion of the protrusions is set to a cut teeth 18, and the inner surface in concrete is gradually cut, thus securely retaining the anchor into a bore hole due to the operation of a cutting surface.

Abstract: PURPOSE: To save weight of a fixing and improve its operational capacity by forming the section of its deformable body into a square, disposing an axial slot and dividing the body into plural leg portions to easily break it, when a clamping member is mounted. CONSTITUTION: A pin 7 has a head portion 8, disposed on the end of a stem 9 on which a circumferential groove 10 and a break point 11 are disposed. A deformable body 15 has a square section and is provided with plural annular flanges 13, 14 with large and small diameters respectively. In this case the body portion 5 is provided with four slots 16, axially extending to the end portion on the side away from each flange 13, 14 and the body portion 15 is divided into four leg portions 17, while a collar 18 is projected from one flange 14, going away from the other flange 13. In this way a fixing is made lightweight and easier to operate and mount.

Abstract: PURPOSE: To obtain a liquid-tight fastening by using a first elastic plastic bushing and a metal end cap which is covered by the outward/backward-expaned bushing when a screw is tightened. CONSTITUTION: A bushing 10 made of neoprene, nitrile rubber, etc., is inserted into a hole 12 of a thin wall 14, and an attachment member 18 to be fixed on the wall 14 is mounted on the flange 16. A screw 20 is screwed to a stamp aperture 22 of a metallic end cap 24 through a bushing 10, and the metallic end cap 24 is engaged with a reduced diameter part 26 of the bush 10. When the screw 20 is tightened, the reduced diameter part 26 is pressed inwardly against the screw 20, and if a stronger force is applied, an increased diameter part 32 of the bushing 10 is expanded outwardly to cover an open end 28 of the metallic end cap 24, and the open end 28 is subject to an inward-radial force. A result is that the metallic end cap 24 is centered to obtain a liquid-tight fastening.
