Improvements to a door frame and a door having an outer edge and an inner edge mounted for movement between an open position of the door withdrawn from the door frame and a closed position of the door received by the door frame, the improvements including bearing components carried by the door frame and the door proximate to the outer edge. One of the bearing components includes a member, and the other one of the bearing components includes a roller. The roller is brought into rolling contact directly against the member as the door is closed and remains in rolling contact directly against the member when the door is closed, positively lifting and supporting the door thereby preventing the door from sagging or binding on the door frame as the door is almost closed and when the door is in the closed position.

An arrangement for guiding a sliding door or folding-sliding door on a furniture wall includes a first guide system to be fastened on the furniture wall and a second guide system to be fastened on the furniture wall at a vertical distance from the first guide system. The two guide systems each have at least one guide and a guide body which is displaceably mounted on the guide, and a carrier on which the sliding door or folding-sliding door is to be fastened and which is connected in a movement-coupled manner to the two guide bodies of the guide systems. The carrier is assembled in the vertical direction from at least two carrier portions, and the at least two carrier portions can be releasably connected.

A garage door carrier system carries an overhead garage door between a closed position blocking entry of a vehicle into a garage, and an open position allowing entry of the vehicle into the garage. The garage door is in rolling engagement with a track that guides the garage door. A lever, rotating about a pivot, has a counterweight at a first end and is rotatably connected to the garage door at a second opposite load end. The counterweight provides in-force at the first end that translates as out-force at the load end as the lever rotates about the pivot to carry the garage door between the closed position and the open position.

An apparatus includes a transfer ball, a rod, a first bracket, a second bracket, a lock nut, an elastic element, and a threaded collar. The rod is coupled to the transfer ball and extends vertically from the transfer ball. The second bracket is positioned above the first bracket. The rod extends vertically through the first bracket and the second bracket. The lock nut engages to the rod and is positioned above the first bracket and below the second bracket. The elastic element is positioned above the lock nut and below the second bracket. The rod extends vertically through the elastic element. The threaded collar is positioned above the elastic element and below the second bracket. The threaded collar is engaged to the rod. The rod extends through the threaded collar.

The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

Anti-fall safety system intended to prevent the detachment of a first component with respect to a second component of an opening and closing system, wherein the first component and the second component are constrained to each other by a reciprocal retainer, in such a way that the first component is mobile with respect to the second component, the safety system having an at least partially flexible elongated means which is provided with at least one engagement element placed in correspondence of one end of the elongated means, the engagement element being intended to engage in correspondence of an engagement point, following the engagement the elongated means preventing the detachment of the first component with respect to the second component.
