A snap structure includes a post, arrowhead-shaped snap pieces, leg pieces, and disengaging pieces. The snap pieces are formed at a distal end of the post and elastically deformable in a radial direction. The leg peices are arranged to oppose the snap pieces. The disengaging pieces are connected each to one end of correcponding one of the snap pieces that are enlarged in diameter, and can reduce in diameter the snap pieces manually. The snap pieces deform elastically in the radial direction, upon insertion in a through hole formed in a chassis or the like, and are fitted in the through hole, so as to clamp the chassis or the like together with the leg pieces. The post includes a stopper portion for prohibiting the post from being inclined in the through hole at not less than a predetermined angle.

A method of removing and retrieving a staple or other fastening device for a plurality of objects, commonly paper, without the use of additional tools. The combined fastening removal and retrieval device comprises a tab of tear-resistant material that is placed on top of or around the objects being stapled or otherwise fastened together. The combination of the stack of papers and the combined fastening removal and retrieval device is then fastened together to form a single object. To remove the fastening device, the user pulls on the tab, which in turn pulls on the fastening device, such as a staple, until the staple or other fastening device is removed from the stack of papers. An additional benefit is that the staple will remain attached to the fastening removal device.

The present invention is directed to a fastener device that includes a base portion. At least one shank is coupled to the base portion. The at least one shank includes an end configured to be driven into a material. The at least one shank also includes a weakened shank region disposed between a first adjacent shank region and a second adjacent shank region. The weakened shank region includes a cross-section irregularly weakened with respect to the cross-sections of the first adjacent shank region and the second adjacent shank region.

A stapler for stapling a tubular structure to another structure. The stapler has an anvil which is expandable from a collapsed position to an expanded position. The stapler has a recess which receives at least a portion of the tubular structure and a shoulder which receives an everted end of the tubular structure. A first actuator moves the anvil relative to the shoulder for compressing the structures which are to be stapled together. A second actuator is used for driving the staples through the structures to be stapled together.

The reverse barb system for screws and nails includes fasteners that are barbed to prevent backing out once driven into a workpiece or construction material, such as wood. A screw with barbed threads has several barbed thread sections. Each barbed thread section is a section of thread having a leading edge and a trailing edge, the trailing edge defining a barb to increase the screw's resistance to backing out once driven into place. A nail with a barbed point is a nail having one or more barbs formed in the nail's point. Each barb is defined by a leading edge and a trailing edge. The barb's trailing edge forms an acute angle with the longitudinal axis of the nail. The barbs extend from the nail shank to prevent the nail from backing out.

A fastener for temporarily fastening a length of wire to the ground includes a U-shaped member having leg portions, a bridge portion bridging the leg portions, and a mount portion arranged at one end of the bridge portion. One of the leg portions has a length greater than the length of the bridge portion, and the mount portion is adapted to receive a visual indicator for identifying the location of the wire. An interior surface defined by the bridge of the U-shaped member captures the wire when the leg portions are inserted into the ground.

An anchor for masonry. The anchor is relatively smooth walled and is forcibly driven into a hole formed in masonry or other suitable material for purposes of attaching fixtures. When driven into the hole, a shaped portion of the anchor is deformed in such a manner as to facilitate a 360 degree or greater bearing surface with the holes of wall. The walls of the hole impose forces onto the shank along this bearing surface which tend to deform shank into alignment with the hole by primarily elastic deformation so that the resulting frictional forces between the shank and the wall resist dislodgment from the hole.

A one-piece band clamp that simplifies the installation of a wire harness. The band clamp includes a band portion whose separated ends form a space, and a pair of insertion members, each formed at an end of a band portion adjacent to the space. The insertion members include insertion plates, lock fingers which include lip portions extending outward and downward from the upper edge of the insertion plates, a lock claw formed on at least one insertion plate, and at least one lock notch formed on the facing insertion plate. The wire harness is inserted into a band portion through the space, the lock claws are hooked over the lock notches to join insertion members, which are then inserted into an aperture in a vehicle body panel. Lip portions of the lock fingers press against the edges of the aperture to secure the band clamp to the vehicle body panel.

There is provided self piercing rivet comprising a substantially planar metal body portion (160) having deformable tabs (161) symmetrically disposed about a slit (162) as per the first embodiment. The upper portion of the body portion (160) is provided with a V-shaped recess (163) diverging from a point (164) adjacent the centreline of the body portion (160) and terminating at the upper edge (165) of the body portion (160). The V-shaped recess (163) divides the upper portion of the body portion (160) into head tabs (166) disposed to each side of the body portion (160). The upper remaining edges of the head tabs (166) enable the rivet to be partially driven and then set by deformation of the deformable tabs (161) and the head tabs (166) against respective sides of the riveted workpiece. Methods of producing the rivets and tools for their use are also provided.

A push-pin including a slot dividing a body into multiple portions and having at least two pins extending from separate ones of the multiple portions. The preferred push-pin includes a pushing surface on one end of the body. A pulling surface is generally defined around the body. The slot divides the body into at least two portions. Material of the body is selected to allow some movement of the divided portions of the body without permanent deformation thereof. This allows the portions return to their relaxed position when an applied force is removed. An opening of the slot has rounded surfaces defined on the body portions. The remaining area defined by the slot 16 may be wider than the opening, allowing an object to be held in the slot after passing the opening. The dimensions of the slot are selected to accommodate different sized objects as a matter of design variation within the scope of the invention. Preferably, the body 12 is made of anodized Aluminum (Al).
