Abstract: The invention relates to a recoilless hammer which comprises a hammer head (2) having a handle seat (4) and a hammer handle (3) to be inserted in said handle seat (4). The handle seat (4) is completely covered in the peripheral direction by an elastic material (5). The end of the hammer handle (3) facing the handle seat (4) is provided with a metal sleeve (7) which is seated with its sleeve end (8) in the material (5) and which is provided with a sleeve collar (12) and, at its free end, with a chamfered section (13) for insertion between securing webs of the handle seat (4).

Abstract: A fluid operated wash brush is provided. The wash brush includes a casing having a downwardly opening top cover. The casing includes a liquid inlet for connection to a fluid supply. The wash brush also includes a rotary wash brush and a mounting shaft supported by the casing for relative rotation on which the rotary wash brush is carried. A retention mechanism is carried on a distal end of the mounting shaft for releasable engagement and disengagement with the rotary wash brush.

Abstract: A riveted joint and a method for forming a riveted joint based on plastic. The riveted joint having a thermoplastically shapeable riveted bolt that can be inserted into a rivet through-hole provided for this purpose in a holding part. To create a rotationally movable riveted joint, a sliding layer, such as a lubricant, is provided on the side of the holding part facing away from the rivet part.

Abstract: The coupling assembly connects at least first and second members of a structure. The first member has at least a first end with an outer surface, and at least one attachment means is located on the first end of the first member. A collar has at least one attachment means for engaging the at least one attachment means on the first end of the first member, the collar being located on the outer surface of the first end of the first member. A cap surrounds at least the collar on the first end of the first member, the cap having a first end oriented toward the first end of the first member and a second end opposed from the first end. The cap has a lip on the second end, the lip being structured to engage the collar to thereby prevent removal of the cap off the first end. The cap has first connecting means at least on the first end of the cap. A base has a first end connected to the second member, and has a second end, opposed from the first end.

Abstract: This invention relates to a rung for a cable ladder which comprises at least one orifice for passage of an attachment member to an upright and two elements in relief disposed on each side of this orifice and adapted to be engaged in an oblong perforation in the upright in which the attachment member is received. In the case of an upright, it is the upright which bears the orifice and the elements in relief adapted to be engaged in an oblong perforation in the rung. A cable ladder according to the invention is easier to assemble due to the self-centering obtained, and the screws or rivets used for attachment are subjected to less shear.

Abstract: By providing a locking member having collapsible and bendable arm members which cooperate with a head-bearing fastening member, a unique fastening system is achieved which enables hardware products, such as handles, knobs, locks, brackets, and the like to be easily and quickly mounted to any desired furniture product. In the preferred embodiment, the head-bearing fastener and the locking member are constructed to be axially inserted through the mounting holes formed in the furniture product. Then, by mounting the fastening system to the hardware product and inserting the mounted fastening system through the mounting holes, the hardware product is quickly and easily securely affixed in position as the collapsible and foldable arm members of the locking member are forced outwardly into an overall width greater than the mounting holes during the threaded advance of the fastener with the hardware product.

Abstract: Easily assembled structures formed by light weight members that are readily and securely joined using a compressible clip. The clip is attached to partially embrace one member and project from it for axial insertion into another member. The inner walls of the latter compress the clip and form the desired junction between the two members. The assemblage can be mounted vertically using elongated hooks.
