The present invention relates to the field of hinges and carriage mechanisms, such as a hinge and carriage mechanism adapted to hang a door, gate, panel, window or the like. The present invention is suitable for use with a means of providing height adjustment for a door and can reduce undesirable tampering and improve the security of the hinges and door assemblies by controlling the orientation of specific part of a hinge to limit access to the fastener.

A pre-hung barn door hardware system is disclosed. The -hung barn door hardware system includes a rail having a plurality of rail holes disposed along a length of the rail; a plurality of spacers each of the plurality of spacers having a spacer hole; a track having a plurality of track holes disposed along the length of the track; a plurality of bolts, each of the plurality of bolts extending through one of the plurality of rail holes, a spacer hole in one of the plurality of spacers, and one of the plurality of track holes; and a plurality of nuts, each one of the plurality of nuts being coupled with a corresponding one of the plurality of bolts.

A support system for use with a door that closes off an opening and a door assembly with the support system. The support system comprises a first support assembly having a main body and a roller assembly connected thereto, the main body comprises a seat for establishing connection with a first position of said door and a connector formed with the seat for connecting with the roller assembly. The connector is displaced from the seat in at least one perspective such that the roller assembly connected thereto is staggered relative to the seat in that perspective.

A looped zebra blind with height compensation and a height compensation method of the same are revealed. The looped zebra blind includes an upper rod, a lower rod and a height compensable looped fabric. The looped fabric consists of a zebra fabric part and at least one compensation part connected to form a loop wound around the upper and lower rods vertically. The loop includes a front fabric and a rear fabric with the same height. The zebra fabric part includes zebra fabric units arranged vertically and periodically. The net length or/height of the compensation part is preset to make total length of the looped fabric become equal to the sum of the total length of the zebra fabric part and the net length of the compensation part. Thereby the height of the front/rear fabric matches up to the preset height of a preset covered area of a window.

A window curtain driving assembly is revealed. A pulley driving assembly is pivotally connected to a main body. Pulleys disposed on the pulley driving assembly slid in a curtain track. Thereby the window curtain driving assembly rotates along curves of the window track so that it can also be applied to the curved window track. An auxiliary pulley set is mounted and fixed on a top of the main body. The pulley mount is oriented toward a given direction by the second latch bar on one side of the pulley driving assembly being mounted in the auxiliary pulley set. Thus the window curtain driving assembly can also be applied to a straight curtain track for extension or retraction of a curtain.

The structures described herein use an actuating system that can selectively switch between a lower and a raise mode of operation by rotating a rod assembly in two different directions, and use a downward displacement of a pull member to lower and raise the window shade depending on its switching state. The actuating systems are simple to operate, allow convenient adjustment of the window shade, and are safe as the pull member has a limited length of extension.

A number of mounting systems are provided for mounting a sheet element with respect to a rail element. In one example, the mounting system includes an elongate mounting tape having a first longitudinal edge portion and a second longitudinal edge portion spaced by a width spacing from the first longitudinal edge portion. The first longitudinal edge portion is configured for being affixed to the sheet element. The second longitudinal edge portion includes a plurality of rail-engaging elements in spaced relationship along the second longitudinal edge portion, the rail-engaging elements being configured for engaging with the rail element and for enabling selective longitudinal movement between the mounting tape and the rail element. The mounting tape is elastically deformable in a width direction, at least when the mounting tape is affixed to the flexible sheet.
