Patent number: 10179681Abstract: A case for holding tools or small parts includes a basic body and a lid coupled pivotably to the basic body. The basic body has two side walls, the upper edge of which is exposed in the closed state of the lid, and therefore the lid, in the closed state, is arranged between the upper edges of the side walls of the basic body. Each side wall of the basic body forms a labyrinth seal with the respective side wall of the lid in the closed state of the case.Type: GrantFiled: December 7, 2015Date of Patent: January 15, 2019Assignee: Adolf Würth GmbH & Co.

Patent number: 8286324Abstract: The invention relates to a blind rivet and a device for placing the blind rivet. The blind rivet contains a rivet head with a collar at one end and a rivet tip at the other. The rivet body contains a cavity in the form of a bore in a sleeve section. As with other blind rivets, the blind rivet is inserted into an opening in two sheets that are to be joined together, until the collar comes to rest on the upper face of the upper sheet. In a second step, the part of the rivet body or the rivet head that lies on the rear face of the two sheets is deformed with the aid of a hammer or expanding body, which is advanced with a percussive-type action in the same direction. A device for placing a rivet of this type contains a part that can be pushed forwards with a percussive-type action, this part consisting of a hammer for exerting pressure on the expansion body.Type: GrantFiled: February 12, 2007Date of Patent: October 16, 2012Assignee: Adolf Wuerth GmbH & Co. KGInventors: Uwe Frank, Marcel Strobel

Patent number: 8192124Abstract: Disclosed is a screw for hard wood, comprising a screw tip (3) with two cutting edges (5) that extend approximately parallel to each other and perpendicular to the longitudinal axis of the screw. The cutting angle of the cutting edges amounts to about 90°. A centering tip (7) which slightly protrudes from the two cutting edges (5) is embodied in the extension of the longitudinal axis of the screw. Said centering tip (7) prevents the screw from deviating to the side at the beginning of the drilling process.Type: GrantFiled: May 25, 2007Date of Patent: June 5, 2012Assignee: Adolf Wuerth GmbH & Co. KGInventors: Frank Wolpert, Juergen Wanner, Andreas Wunderlich

Patent number: 6655472Abstract: A device for producing an abrupt or sudden feed motion contains in a casing a feed device, which can be triggered by a trigger. The force necessary for advancing the feed device is applied by a spring, which is tensioned with the aid of a drive. The tool requires no cartridges for propellant charges.Type: GrantFiled: July 12, 2001Date of Patent: December 2, 2003Assignee: Adolf Wuerth GmbH & Co. KGInventors: Siegfried Humm, Dirk Schroeter

Patent number: 6640911Abstract: A device for connecting a tool to a mechanical drive contains as the coupling element a spring washer coupling or clutch, which is made in one piece from metal and at least in the rotation direction has a limited resilience. Use is made thereof for preventing torque peaks in the case of a sudden deceleration of the tool, e.g. if a screw strikes a wood surface.Type: GrantFiled: May 25, 2001Date of Patent: November 4, 2003Assignee: Adolf Wuerth GmbH & Co. KGInventors: Karl Lieser, Andreas Dierolf, Frank Kollmar

Patent number: 6629338Abstract: The invention proposes a handle for a screwdriver or a similar tool, which over a significant part of its length has a cross-section in the form of an approximately regular pentagon. The corner or angle sections are rounded with a radius of curvature, whose centre is in the longitudinal axis of the tool handle. The corner sections formed by the curved part of the cross-section have a different width over the handle length. The shape of the flattenings does not follow the shape of the handle contour.Type: GrantFiled: September 12, 2001Date of Patent: October 7, 2003Assignee: Adolf Wuerth GmbH & Co. KGInventors: Andreas Dierolf, Karl Lieser

Patent number: 5219375Abstract: The riveter of the invention comprises a shaft, a rolling nut, a jaw mechanism, a head frame, a rotary drive shaft, a clutch mechanism disengageably coupling the rolling nut with the rotary drive shaft, a generally cylindrical journal frame and a cylindrical main frame. After a blind rivet having a drill point is inserted into a nose piece of this riveter, the main frame and rotary drive shaft are rotated in a suitable manner, whereby the desired drilling of the rivet hole and riveting operation can be accomplished. The riveter may alternatively comprise a shaft, a rolling nut, a jaw mechanism, a head frame, a rotary drive shaft, a rear clutch mechanism disengageably coupling the rolling nut with the rotary drive shaft, a generally cylindrical journal frame, a cylindrical main frame, a front cover, a rear cover and a forward clutch mechanism.Type: GrantFiled: May 9, 1991Date of Patent: June 15, 1993Assignees: Lobster Tool Co., Ltd., Adolf Wuerth GmbH & Co.
