Patent number: 7506404Abstract: The invention relates to a caster comprising a trailing wheel, a fork and an assembly journal. The fork can be swiveled in relation to the assembly journal and inside the fork a braking device is disposed which can be displaced into the braking position via a tappet actuated by a trip cam. The aim of the invention is to provide a direction-lockable caster that has a simple design. For this purpose, the tappet interacts with a direction locking part mounted stationarily on the fork, when spring biased into a direction locking position.Type: GrantFiled: April 20, 2005Date of Patent: March 24, 2009Assignee: TENTE GmbH & Co. KGInventors: Wolfgang Block, Manfred Milbredt

Publication number: 20070044273Abstract: The invention relates to a running wheel of a roller such as a caster wheel or a fixed caster, comprising a hub body, in particular a hub body made of polyamide, and a running surface. The hub body is produced according to a plastic injection method. In order to further develop the generic running wheel and to improve the production and advantages of use, the running surface is embodied on a tube part and the tube part comprises a filling made of plastic and/or rubber material.Type: ApplicationFiled: October 24, 2006Publication date: March 1, 2007Inventor: Manfred Milbredt

Publication number: 20040117943Abstract: The invention relates to a roller (1), in particular, a castor. The rotation of the running wheel of said castor and optionally the pivoting motion of the running wheel (12) may be fixed, by means of an operating shaft (20), which moves a control cam (19) through the roller (1), with an electric motor (37) acting thereupon for operation thereof. According to the invention, the functional roller operation can be embodied with a more advantage operation, a simpler construction, yet of secure operation, whereby the electric motor (37) acts on the operating shaft (20) by means of an electric motor shaft (39) using a toothed gear (38).Type: ApplicationFiled: January 16, 2004Publication date: June 24, 2004Inventors: Wolfgang Block, Manfred Milbredt

Patent number: 6584641Abstract: A castor (1) has a securing device (V) for blocking running action and/or steering action of a wheel (2) mounted in a fork (3). A mounting of the fork (3) permits pivoting about a vertical axis (y—y). A push rod (11) operates an integrally formed combination part (K) located at the fork for providing functions of braking-blocking and/or steering blocking formation. The push rod (11) carries a plate (23) configured for interacting with fork-mounted steering-blocking and braking-blocking parts of the combination part (K), which has steering-blocking mating protrusions (25) and braking-blocking means (26), these being located in spaced-apart planes (E′—E′, E″—E″).Type: GrantFiled: April 12, 2001Date of Patent: July 1, 2003Assignee: Tente-Rollen GmbH & Co.Inventor: Manfred Milbredt

Patent number: 5133106Abstract: The present invention relates to a caster (1), in particular a steering roller having a wheel (5, 6) and a locking device, the locking device having a setting element (7) and engagement element (9) which cooperates with the setting element so as to block the travel of the wheel (5, 6) in which a linear setting movement of the setting part (7) can be transmitted via a wedge transmission (10) to the engagement element (9). In order to achieve a development which is as simple as possible from a design standpoint and also has advantageous kinematics, the invention proposes that the engagement element 9 be arranged guided for linear movement in order to effect a linear engagement movement with respect to the wheel (5, 6).Type: GrantFiled: September 27, 1990Date of Patent: July 28, 1992Assignee: Tente-Rollen Gesellschaft mit beschrankter HaftungInventors: Manfred Milbredt, Wolfgang Block

Patent number: 5083341Abstract: A twin caster, in particular a steering caster, having a carrier (3), wheels, and a vertical mounting pin (22), the wheels being held via an axle (6) on the carrier (3) and the carrier (3) supporting the mounting pin (22), a brake element (32) being furthermore arranged on the carrier (3). For simplified construction, easier assembly, and a development which takes up high brake forces without damage, the carrier (3) is developed in disk shape and have an opening (39) for lateral insertion in the form of a plug/back-grip connection for the brake element which is developed as brake ram (32).Type: GrantFiled: August 3, 1990Date of Patent: January 28, 1992Assignee: Tente-Rollen GmbH & Co.Inventors: Manfred Milbredt, Wolfgang Block
