Patent number: 5406677Abstract: A press-fit hinge cup for a hinge is anchored in a recess in a furniture portion, preferably in a door portion, and the anchoring means consists of tabs which project radially outwardly from the side wall of the hinge cup into the material of the peripheral wall of the recess of the furniture portion. In order to avoid excessive weakening of the material of the peripheral wall of the furniture portion and to ensure secure fitting of the hinge cup in the furniture portion respective upper or distal edges of the tabs are located at different distances from the base of the hinge cup relative to each other. As a result these tabs engage in the peripheral wall of the furniture portion along different contour lines in the recess. Additional splay tabs defined by slits positioned substantially perpendicularly to the hinge cup's base and pressed outwardly into the peripheral wall of the recess may be provided. The splay tabs provide additional resistance to twisting of the hinge cup in the recess.Type: GrantFiled: August 10, 1993Date of Patent: April 18, 1995Assignee: Grass AGInventor: Alfred Grass

Patent number: 5388309Abstract: A hinge for insertion in a recess in a furniture portion (e.g. a door) including a press-in cup for engagement with the recess and rotary cup which is engageable with the press-in cup by a rotary action. Pairs of complementarily engageable tabs are provided on the bases of the cups. Further pairs of complementarily engageable engagement tabs are provided on side walls of the cups which provide a camming action tending to urge the cups together as they are engaged. The base of the press-in cup is provided with a resilient detent tongue which springs into place when the cups are connected and resists inadvertent disconnection. Manual depression of the detent permits the cups to be separated.Type: GrantFiled: September 1, 1993Date of Patent: February 14, 1995Assignee: Grass AGInventor: Alfred Grass

Patent number: 5348386Abstract: A drawer is described which comprises side walls, a back wall, a front panel and a drawer bottom. In order, for transport purposes, to reduce the amount of room which the drawer takes up, it is provided that the drawer side walls and the back wall are coupled in a hinge-like manner to the drawer bottom and that the front panel is detachably connected to said parts. There is provided on the drawer bottom a downward-directed projection which engages in an open groove of a side wall or of the back wall and fills the groove force-lockingly in the manner of an initial tension, the groove having an inward-directed hook-like projection and an opening through which the projection of the drawer bottom engages. Front panel connectors are additionally provided on the side walls for connection to the front panel.Type: GrantFiled: May 10, 1993Date of Patent: September 20, 1994Assignee: Grass AGInventor: Alfred Grass

Patent number: 5314253Abstract: A rolling element guide for drawer guides consists of a furniture unit body rail mounted on the furniture unit body side wall and a drawer rail mounted on the drawer, rolling surfaces for the rolling elements transmitting the drawer load being arranged on both rails, the rolling elements being held in a roller cage arranged between the rails. For minimizing the rolling noise and for reducing the manufacturing costs, the rolling elements have pins on opposing end faces, these pins pivoting in the roller cage, the pins of rolling elements arranged in the same plane being staggered 90 degrees with respect to each other, which forms rolling surfaces on the rolling elements that are staggered 90 degrees with respect to each other, and high drawer loads can be transmitted.Type: GrantFiled: February 9, 1993Date of Patent: May 24, 1994Assignee: Grass AGInventor: Alfred Grass, Jr.

Patent number: 5239730Abstract: Described is a hinge with a rotary cup and a press-fit cup at the end of the hinge-joint, in which for assembly the rotary cup is inserted into the press-fit cup on the door side and for fastening is twisted in a bayonet-like manner. In order to prevent damage by parts projecting at the top, the press-fit cup is provided with lateral walls of reduced height in such a way that the press-fit cup is completely countersunk in the cup drilling on the door side and that from the bottom of the press-fit cup rise up bent portions which, through turning, are engaged by lugs of the rotary cup.Type: GrantFiled: June 23, 1992Date of Patent: August 31, 1993Assignee: Grass AGInventor: Alfred Grass

Patent number: 5088155Abstract: Described is a single-articulation hinge with an adjusting arrangement for lateral adjustment and for vertical adjustment, the invention providing a snap-in connection between the door-side section and the frame-side section of the door hinge. Rapid assembly is achieved thereby, because the two-part door hinge is completed through simple sliding together of an intermediate plate mounted on the door side and of a frame-side base plate screwed onto the body of the furniture unit. A snap-in connection is carried out preferably with the help of a spring, which separably connects the two parts.Type: GrantFiled: September 7, 1990Date of Patent: February 18, 1992Assignee: Grass AGInventor: Alfred Grass

Patent number: 4881826Abstract: An under-base guiding system for a drawer of a piece of furniture is described, wherein the body of the piece of furniture is provided with sidewalls, a front batten, and rails having guide rollers, and wherein the drawer is provided with rails having guide rollers.The body rails are situated below the base of the drawer, and are secured to the front batten of the body by a front connector and to the rear wall of the body by a rear connector. The drawer rails and body rails interengage beneath the drawer base via the guide rollers.Since the guiding system is located under the base of the draw, it possesses the advantage that it can be concealed, and can provide maximum space utilization of the drawer, relatively great strength, and ease of adjustment.Type: GrantFiled: June 14, 1988Date of Patent: November 21, 1989Assignee: Alfred Grass Ges.m.b.H.

Patent number: RE34108Abstract: A pull-out guide for drawers consists of two 2 frame sides, U-shaped guide rails and Z-shaped pull-out rails movable therein, both the guide and pull-out rails being provided with a roller each, and the lower guide legs of the U-shaped guide rails having in their end areas run-in slopes adjoined by run-in stops each, and the front end areas of the upper pull-out rail legs, serving as rolling surfaces for the rollers, having a run-in slope each oriented in the same direction and preferably parallel to the run-in slope in the end area of the guide rail on the frame side. This improves the pull-in and staying closed behavior when drawers of little net weight and small load capacity are involved. Because the legs of both rail pairs of the pull-out guide run parallel, the front blind is approximately jointlessly flush with the frame.Type: GrantFiled: July 12, 1991Date of Patent: October 20, 1992Assignee: Grass America, Inc.Inventor: Alfred Grass
