Patent number: 8899633Abstract: The present disclosure relates to a lock device, such as for safety functions, which includes a displaceable lock bolt, which can cooperate with a receiver in order to provide a locked position and unlocked position. The lock bolt includes a guide portion in a second lock bolt portion which, in response to a guiding device applying a force to the lock bolt, guides the lock bolt from the unlocked position to the locked position. The guiding device, in the locked position, is prevented from displacing the lock bolt to the unlocked position. The lock bolt is arranged to be displaced from the locked position to the unlocked position through influence of an external force applied to a first lock bolt portion.Type: GrantFiled: October 15, 2010Date of Patent: December 2, 2014Assignee: ABB ABInventors: Mats Linger, Lars-Magnus Felth, Ingvar Gillholm, Mattias Bokesand, Martin Bredberg

Patent number: 7096380Abstract: The present invention relates to a programmable safety system intended to be used for safety functions, in which a fault in a control circuit does not lead to a safety function being disabled, which system comprises monitoring functions containing at least two control units, input terminals separately coupled to both control units, whereby each control unit executes its own instruction set and continuously compares a result from the execution with each other. At least one control unit can access the in and output terminal status of a second control unit and/or a number of flags, and the control units are arranged to monitor the result of respectively executed instruction sets and control that the results of the executions are substantially equivalent.Type: GrantFiled: December 11, 2002Date of Patent: August 22, 2006Assignee: Jokab Safety ABInventors: Mats Linger, Göran Svensson

Patent number: 6733221Abstract: Insert nut for a screw nut joint of the type which comprises a substantially rectangular block, of which the short side substantially corresponds to the width of the outer groove portion in a T-formed groove, which outer groove portion is delimited by side flanges in a profile or the like and which inner groove portion is expanded relative to the outer groove portion. The long side of the insert nut substantially corresponds to the width of the inner groove portion, and which nut by rotation can be transversally positioned and be brought into contact with the underside of the side flanges of the groove. The nut is designed with a substantially quadratic shoulder section, which is arranged concentric with the threaded hole of the nut, and with substantially the same width as the short side of the nut.Type: GrantFiled: October 28, 2002Date of Patent: May 11, 2004Assignee: Jokab Safety ABInventor: Mats Linger

Patent number: 6603306Abstract: A proximity switch for detecting a target in proximity with the proximity switch as a wireless transmitter for transmitting a first pulsed signal having a first carrier frequency to the target. The proximity switch also includes a wireless receiver for receiving a second pulsed signal having a second carrier frequency different from the first carrier frequency from the target. The proximity switch has a controller for providing an output indicative of whether a predetermined correspondence is satisfied between the first and second pulsed signals.Type: GrantFiled: February 8, 2002Date of Patent: August 5, 2003Assignee: Jokab Safety ABInventors: Torgny Olsson, Gunnar Widell, Mats Linger

Patent number: 6392169Abstract: A safety device for control of working apparatuses, e.g. presses, for which start and operation modes depend on essentially simultaneous activation of two separate operating devices, which are each controlled by the respective hands of the operator. Each operating device consists of two separate push buttons. The push buttons are arranged in a housing at a mutual distance from each other, which requires a two-hand operation, e.g. with at least two fingers. The push buttons are situated at a distance from each other.Type: GrantFiled: April 21, 2000Date of Patent: May 21, 2002Inventors: Mats Linger, Torgny Olsson, Gunnar Widell

Patent number: 6331092Abstract: A corner joint for profile sections (13) provided with one or more longitudinal channels (16), in connection with the outside of the profile section via a likewise longitudinal slot opening (12). The channel (16) constitutes an attachment for a nut means (11) which cooperates via screw means (14) with connector fittings (17, 24). Each screw means (14) is provided with a lock means (10) which is located in the slot opening (12) between the nut means (11) and the connector fittings (17, 24). The lock means (10) is provided with a screw opening (15) and means (20) for locking the nut means (11) against rotation out of a locking position. The lock means (10) is also provided with at least one boss (23) which during rotation of the nut means (11) from its locking position cooperates with a shoulder (22) on said nut means, in order to position the nut means and facilitate its removal from the channel (16).Type: GrantFiled: September 30, 1997Date of Patent: December 18, 2001Inventor: Mats Linger
