Abstract: A brake device for damping a translatory motion having a bearing housing and a brake disk both made of a resilient, hard elastic plastic material. The brake disk is supported for rotation in the bearing housing and adapted for rotation in response to a translatory motion, the brake disk having an outer conically shaped friction surface and the bearing housing a correspondingly configured inner conically shaped friction. The surfaces are held together when the disk is supported in the housing to generate frictional resistance between them as the disk rotates in the housing in response to a translatory motion and thereby dampen the motion.

Abstract: A pipe bracket of hard-flexible plastic for holding at least two parallel running pipelines, comprising two substantially identically shaped parts that can be assembled together to form the bracket, each part comprising a base member, at least two spaced retaining grooves in the base member for receiving at least two pipelines in parallel relationship, a flexible clamping inner leg extending upwardly from said base member between adjacent pipelines and two outer flexible clamping legs extending upwardly from said base member along the outer sides of the two outermost pipelines, each of said inner and outer legs forming with an adjacent leg and at least a portion of the axial length of a retaining groove, a U-shaped holder for holding a pipeline, each of said legs having a slanted surface as its upper end for guiding a pipeline into a holder and having a laterally protruding flexible detent at the end of said slanted surface that extends partly over the opening of the holder and engages the pipes' circumferenc

Abstract: Disclosed is a clamp for securing a round article to a support plate. The clamp includes a generally channel-shaped body having a clip which cooperates with one of the legs of the body to retain the article in the channel opening. The clip has a head having an arcuate surface engageable with a surface portion carried by the other leg of the channel-shaped body to prevent removal of the article from the clamp upon application of a tensile force on the article in the direction of the clamp opening. To remove the article, the clip is manually displaced toward the base of the channel body to open the clamp. In another embodiment, a pair of clips lie in opposition one to the other and each clip cooperates with a surface portion carried by a corresponding leg of the clamp to preclude removal of the article from the clamp upon application of a tensile force in a direction tending to remove the article from the clamp through its opening.
