  • Patent number: 10150151
    Abstract: A metal tab bending tool for securing an upright stud in place and relative to an elongated track of a wall assembly. The track includes an elongated flat web with first and second free-ended flanges extending in the same direction from opposed first and second side edges, respectively, of the web. Each flange of the web defines a plurality of spaced tabs extending toward the flat web from a free-end of each flange. The tool for connecting the stud in place and relative to the track includes a base. The tool also includes at least two pairs of bending arms each pivotally mounted to the base. Each pair of bending arms includes a first bending arm, adapted to be disposed to one side of the upright stud, and a second bending arm spaced apart from the first bending arm and adapted to be disposed to an opposite side of the stud.

  • Patent number: 9808052
    Abstract: A hand tool adapted to manipulate and open split rings is provided. The hand tool has two elements both having handles operatively associated so that the distal end jaw portions of the elements are movable between a closed and an open position. An opening jaw has a penetrating probe for opening convolution of a split ring, while the opposing supporting jaw provides a supporting surface acting as an anvil providing opposing force to the other linear elements probe. The split ring is generally disposed around the spaced apart opposing jaws, permitting the probe to penetrate the convolutions over a deeper range because there is no limitation created by the opposing jaw.

  • Patent number: 9597947
    Abstract: A method of assembling vehicle-body components includes positioning a first component on a second component. The first component has a different coefficient of thermal expansion than the second component and one of the first and second components defines a slot. The method also includes loosely installing a bolt though the slot and the first and second components, and creating a joint in the first and second components. The method further includes heating the first and second components, which causes the first and second components to move relative to each other due to thermal expansion in response to the heating. This movement causes the joint to fail. The method also includes tightening the bolt.

  • Patent number: 9411301
    Abstract: A frame for an image forming apparatus, includes: first and second plate members; a bent portion provided as a part of the first plate member and bent along the second plate member; a portion-to-be-fixed provided as a part of the bent portion; a positioning portion, provided on the first plate member, for positioning the second plate member relative to the first plate member by being abutted vertically against the second plate member, wherein a free end projects toward the second plate member more than the portion-to-be-fixed; and a fixing portion, provided as a part of the second plate member, to which the portion-to-be-fixed is fixed. The second plate member is deformed to contact and deform the fixing portion to the portion-to-be-fixed while the second plate member is in contact to the positioning portion, so that the first plate member and the second member are fixed to each other.

  • Patent number: 8240678
    Abstract: Provided is a connecting structure in which it is difficult for a crack to occur, even if a connection location is set in a portion on which concentrated tensile stress may occur. Laminated metal plates are concurrently punched out downward in shape of tongue piece. A depth of punch-out is not smaller than a total thickness of the laminated metal plates. A tongue piece portion is punched out in shape of cantilever beam while a central connection portion is left behind. The tongue piece portion is bent downward in the out-of-plane direction at a connection portion linking to the central connection portion in order that a location of the tongue piece portion in the extension direction on its way is parallel to a bend line. The tongue piece portion is configured to widen in width gradually toward a front end thereof.

  • Patent number: 7322086
    Abstract: A method of attaching a functional element (10, 210), in particular a fastener element to a sheet metal part (12, 212), optionally in liquid and/or gas-tight manner, is characterized in that the functional element (10, 210, 410) is pressed against the sheet metal part (12, 210, 410) supported by a die (14, 114, 214, 414) and sheet metal material (13) is pressed by means of at least one movably mounted shaped part (16, 116, 216, 416) of the die (14, 114, 214, 414) into an undercut (18, 218, 418) of the functional element (10, 210, 410). The disclosure also claims a die, a functional element, and a component assembly comprising the functional element and a sheet metal part.

  • Patent number: 6446407
    Abstract: A grid tee of the double web type in which the elements of the web are integrally stitched together to prevent their separation. The stitches are created in an inexpensive rolling process that does not require control of the position of the stitches relative to the ends or other parts of the tee. According to the invention, after the stitches are formed and locked, they are flattened back into the plane of the web to a limited degree where they do not substantially increase the thickness of the web so that they do not interfere with subsequent manufacturing steps or with field assembly.
