Abstract:
A bearing arrangement having at least two parts (10, 12) rotatable relative to one another, in which one (10) of the parts has at least one annular groove (14) concentric with the axis of rotation (A), and the other part (12) has a tongue (16) that is complementary to the groove (14) and engaged therein, and in that each of the parts (10, 12) is divided into at least two sectors (10a; 12a) along separating faces that pass through the groove (14) and the tongue (16), the tongue (16) extending over all sectors (12a, 12b) of the corresponding part (12).
Abstract:
A drive device for opening or closing a leaf of a door, a window or similar includes a housing and a closing spring, which is located in the housing and acts upon a piston, the latter co-operating with a closing shaft in the housing by means of gearing, The piston and housing are made of injection molded polyoxymethylene plastic (POM).
Abstract:
An apparatus is disclosed for correcting misalignment problems in a casement window. An adjustment stud is included in an improved casement window unit. The adjustment stud includes a tenon mounted on a track assembly and a post to which a sash arm is rotatably attached. The tenon and post are eccentric with respect to one another. When alignment problems occur the central axis of the post may be rotated about the central axis of the tenon to a desired orientation such that the alignment problem is corrected.
Abstract:
A connection for adjustably holding two window hardware members in pivotally connected relationship, including a first hardware member with a first cylindrical opening, a second hardware member with a second cylindrical opening, and a stud. The stud has a flange having two substantially parallel faces and a peripheral surface therebetween, with a rivet portion projecting from one face and a pivot portion projecting from the other face. The rivet portion includes a cylindrical neck extending through the first cylindrical opening and a head on the end of the neck, the flange and the head engaging opposite sides of the first hardware member to frictionally secure the stud against freely pivoting relative to the track. The pivot portion includes a cylindrical shaft eccentric from the cylindrical neck and extending through the second cylindrical opening. A C-ring is disposed in an external peripheral groove in the pivot portion to secure the second hardware member thereto for pivoting about the cylindrical shaft. A part of the C-ring is in the peripheral groove and a part extends radially beyond the pivot portion periphery when the C-ring is in a securing position. The peripheral groove has a depth to enable deformation of the C-ring by movement of the spaced-apart ends towards each other to a release position in which substantially all of the C-ring is in the peripheral groove. The stud flange peripheral surface is engageable with a tool to allow for adjustment of the pivotal connection by pivoting the stud.
Abstract:
A friction supporting stay comprises a channel section track (10) and a slider (15) linked to a strut (24). At the upper and of track (10) is a cap (14) with internal surfaces (36) (37) engageable by one end of strut (24). A plastic nose member (35) is riveted to the end of strut (24) and is formed with surfaces (39) (40) shaped to engage the corresponding surfaces (36) (37).
Abstract:
Die Erfindung betrifft eine Laufrolle (38) mit einem Laufkörper (58), insbesondere aus elastischem Material, der eine Lauffläche (60) aufweist. Der Außenring (54) weist einen Laufrollenkranz (90) auf, der den radial am weitesten von der Drehachse (44) der Laufrolle (38) vorstehenden Teil der Laufrolle (38) bildet. Der Laufkörper (58) kann in eine Aufnahmenut (56) eines Außenrings (54) der Laufrolle (38) eingebettet sein. Seitenwände (62, 64) der Aufnahmenut (56) schließen vorzugsweise radial bündig mit dem Laufkörper (58) ab. Im Nutgrund (70) der Aufnahmenut (56) kann eine erste Ausnehmung (74) ausgebildet sein, in die der Laufkörper (58) eingreift, sodass ein Ausdrehen des Laufkörpers (58) aus der Aufnahmenut (56) um das Zentrum der Lauffläche (60) effektiv verhindert wird. Vorzugsweise ist im Nutgrund (70) eine zweite Ausnehmung (76) ausgebildet, in die der Laufkörper (58) eingreift. Die zweite Ausnehmung (76) ist bevorzugt umlaufend im Außenring (54) ausgebildet und verläuft parallel zur ersten Ausnehmung (74). Die Laufrolle (38) kann spiegelsymmetrisch zu einer Mittenebene (42) ausgebildet sein, die senkrecht zur Drehachse (44) der Laufrolle (38) verläuft.
Abstract:
A hinge device for rotatably moving a closing element (D), comprising a fix element (11) anchorable to the stationary support structure (S) coupled to a movable element (10) anchorable to the closing element (D) for rotating around a first longitudinal axis (X) between an open position and a closed position. The device further includes at least one slider (20) movable along a respective second axis (Y) between a compressed and an extended position. One between the movable element (10) and the fix element (11) includes at least one operating chamber (30) defining the second axis (Y) so as to slidably house the slider (20), the other element comprising a pivot (40) defining the first axis (X). The pivot (40) and the slider (20) are reciprocally coupled so that to the rotation of the movable element (10) around the first axis (X) corresponds the sliding of the slider (20) along the second axis (Y) and vice versa.
