  • Patent number: 6435792
    Abstract: An improved sleeve for insulating a tacking strip from materials applied to furniture products. The sleeve covers and encompasses the entire tacking strip with the exception of a central corridor through which tacks from the strip extend. The sleeve slides over the tacking strip and includes a flexible flange graduated in thickness on either side of a central corridor left open by the sleeve. The sleeve is installed around the tacking strip by a lateral displacement of the sleeve over the strip causing the graduated flanges to deform slightly upon contact with each tack along the central corridor. Due to the deforming properties of the flange, resistance on each tack is small enough that insertion of the sleeve over the tacking strip not hindered yet sufficient to prevent further lateral displacement of the sleeve once it is installed around the tacking strip.

A fastener having a tip or point at one end is inserted between a glass and a frame. The fastener has a pair of fins extending substantially perpendicularly from one surface and away from the glass. When appropriate mechanical forces are applied, the fins are bendable toward each other and have a tendency to return to their approximate original position after the forces are released. A slot is provided in the surface of a bar grille which comes into contact with the glass. The bar grille is snapped on the fastener so that the fins are forced toward each other as they enter the slot and are hooked into position as the fins return to their approximate original position. The bar grille may be removed by pulling on the grille so that fins disengage from the slot.

  • Patent number: 4627777
    Abstract: An attachment means for mounting decorative borders consisting of at least two identical nail-like parts, each part having an elongated section, one end of which gradually narrows and the other end of which forms a member having two trapezoidal-shaped heads. The trapezoidal head parts are separated by a V-shaped notch and are bent at an approximate right angle relative to the elongated section of the part so that the head forms two protruding teeth. The elongated section has a longitudinal bend and a slot which coincides with the bend. The bend, the width of the elongated section, and the width of the slot are mutually matched so that the elongated section of one part can be inserted with a friction fit into the slot of an identical other part. When using the attachment means the elongated section of one part is inserted with friction fit into a pre-bored hole and the teeth are pushed into a border which is then affixed.

  • Patent number: 4514126
    Abstract: An improved corrugated staple or fastener for joining together wood members such as wood chords to form a joist-like wood beam. The staple, which is made of sheet metal, has corrugations oriented at three different angles relative to a reference line such as the edge of the staple which is to be inserted into the wood members. The corrugations which are oriented at the first and second angles pull the wood chord members toward each other and when the joist-like beam is subjected to loading, the orientation of the first and second corrugations compresses the wood chords toward each other and increases friction between the chords. The third corrugation is oriented so that when the staple is inserted into the wood chords, the fibers of the wood are temporarily displaced and thereafter move back toward their original position to resist any tendency of the staple to pull out of the chords. The third corrugation also increases the resistance of the staple to horizontal shear forces or bending.

  • Patent number: 4486999
    Abstract: An open ended tubular body member has a continuous defining side wall formed of rigid sheet material of high tensile strength. This body member is arranged to be driven into the end of a wood pole longitudinally with the grain. The side wall is contoured to have a plurality of adjoining wall portions with adjacent ones of the wall portions being disposed angularly relative to each other and each arranged to intersect the growth rings of the wood in a diagonal direction. The device resists radial checking of the pole due to aging of the pole or moisture changes and also reinforces the pole whereby mounting bolts for brackets or cross arms are arranged to have a positive securement to a pole.

  • Patent number: 4433949
    Abstract: A fastener having an integral head and shank which are formed from a strip of sheet metal of indeterminate length in which the head is formed by slitting and compressing a section from one edge of the sheet material to provide a split head having two substantially similar halves with at least a portion of each half being generally perpendicular to the shank and with at least a portion of the head being thicker than one-half of the thickness of the sheet material and in which the forming of the head causes a slot in the upper surface of the head which is less than one-third the thickness of the sheet material.

  • Patent number: 4263830
    Abstract: The disclosure relates to a fastening device for driving into building material, the device consisting of one or more elongate V profiles whose shanks, in the vicinity of the forward, penetrating end of the profiles are outwardly relieved or bevelled such that building material, on driving of the device into the material, is trapped between the shanks and forces them apart. A tip at the forward end of the profile is designed such that, on being driven in, it moves in the driving-in direction.

  • Patent number: 4255914
    Abstract: A clip for securing planar members, such as tongue and groove pine boards, panel boards and flooring, to wooden supports, such as furring strips. The clip is formed from a metal plate and has first and second portions struck out from the plate. The first and second portions both extend outwardly from the plate in the same direction. The first portion is angularly bent so as to form an L-shaped finger member capable of engaging a peripheral edge of the planar member to be secured to the furring strip. The second portion has a free pointed end and is angularly bent so that it can be driven back across the plane in which the plate lies and then driven into the wooden support member to which the planar member is to be secured.
