Patent number: 11052704Abstract: The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.Type: GrantFiled: November 29, 2017Date of Patent: July 6, 2021Assignee: GROSS + FROELICH GMBH & CO.Inventors: Hans-Wilhelm Rottenau, Ralph Von Bordelius

Publication number: 20190118578Abstract: The invention relates to a roller, in particular furniture roller, having a housing which is rotatably fastened, by means of a runner pin arranged vertically in an opening of the housing, to an object to be supported by the roller, wherein the runner pin has a first section which is arranged in the opening of the housing and a second section which projects beyond the housing. To create, in a simple and cost-effective manner, a runner pin which permanently prevents an undesired generation of noise as a result of relative movements between the runner pin and the object to be supported, it is proposed according to the invention that at least two annular grooves are provided in that section of the runner pin which projects beyond the housing, in which annular grooves in each case one elastic retaining ring is arranged without play.Type: ApplicationFiled: December 14, 2018Publication date: April 25, 2019Inventors: Ralph Von Bordelius, Oswald Flik

Patent number: 8454098Abstract: The invention relates to a wheel for a furniture roller having a locking device, having a rigid wheel core with a hub for holding an axle and having an elastic wheel casing as a running surface. According to the invention, in order to be able to realize a locking device which is effective even for small wheel diameters, an inwardly pointing toothing is provided on an outer ring of the wheel core, wherein at least one aperture is formed in the outer ring between the tooth flanks, into which aperture a web, which is aligned axially in parallel and which is offset radially inward with respect to the running surface, of the wheel casing engages in a positively locking manner.Type: GrantFiled: February 24, 2009Date of Patent: June 4, 2013Assignee: Gross + Froelich GmbH & Co. KGInventors: Ralph Von Bordelius, Oswald Flik

Patent number: 8397345Abstract: The invention relates to a castor having a brake device with a housing (10) with a substantially vertically aligned receiving opening (12) for a runner pin (14) for connecting the castor to an object to be supported by the castor, and having an axle bolt (16) which extends through the housing transversely with respect to the receiving opening and which bears at least one wheel (18, 18?), with the brake device having a brake slide (20) which can be moved by an actuating lever (22) from the outside from a free-running position into a braked position. To provide inter alia a locking facility independently of the rotational position of the wheel, it is proposed according to the invention that the brake slide (20) bears an elastic brake lining (36) which faces toward a braking section (32) of the at least one wheel.Type: GrantFiled: July 13, 2010Date of Patent: March 19, 2013Assignee: Gross + Froelich GmbH & Co.

Patent number: 8151412Abstract: A caster, in particular a free-running caster is provided. The caster includes twinned wheels and a housing with a substantially vertically aligned upper-side journal opening for holding a rotary journal which connects the caster to an item of furniture or to some other object. The caster also has an axle bolt which extends through the housing transversely with respect to the journal opening and supports the wheels. In order to permit cost-effective production with sufficient load capacity in the region of the axle receptacle, an axle carrier having a passage opening for the axle bolt is arranged in the housing. The axle carrier is composed of a material with a higher strength than the housing.Type: GrantFiled: October 19, 2007Date of Patent: April 10, 2012Assignee: Gross + Froelich GmbH & Co. KGInventors: Ernst Berger, Ralph von Bordelius
