A sash (62) of a window opening up to 180° and capable of tilting is mounted onto a fixedly installed frame profile (63) and houses a pair of superimposing sashes that fit tightly therein when in closure position, i.e. an upper stationary sash (65) and a lower movable-divertible sash (64), each of the sashes (64,65) provided with laterally extending shafts (49) for connection with sash (62), roller wheels (50) provided onto the shafts (49) of sash (64) that roll within a predefined path created by insert guide profile members (19) and diverter guide members (66,68) to alternately bring sash (64) in a position of superimposing sash (65) and a position of alignment with the same. Lifting mechanisms (46) provided with a regulatory screw (84) for adjusting the pretension of a spring component thereof and thereby the force required by the user for moving the sash (64) are installed within the vertically extending sides of the sash (62).

The present disclosure is directed to overhead doors and overhead door operation. More specifically, the present disclosure relates to a direct drive counter balancing system for operating overhead doors. In some examples, the direct drive counter balancing system of the present disclosure is for overhead door systems used in segmented door arrangements for box trucks.

A protective shroud includes a shroud body, a protective door movably installed on the shroud body, and a buffer mechanism connected between the shroud body and the protective door. The buffer mechanism slows down a moving speed of the protective door. The protective door is moved between an open position and a closed position in a vertical direction to open or close the shroud body.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

A sliding closet door leaf is provided with a shuttle connector (40a) configured to connect the door leaf to a soft closing mechanism shuttle (60a) arranged in a door guide, and the soft closing mechanism shuttle (60a) comprises a door leaf connector (62a) configured engage with the shuttle connector (40a), wherein the shuttle connector (40a) is connectable to the door leaf connector (62a) at anyone of at least a first mutual vertical relationship between the door leaf and the soft closing mechanism shuttle (60a), and a second mutual vertical relationship between the door leaf and the soft closing mechanism shuttle (60a).

A junction box assembly including a box and a selectively displaceable lid, the lid including one or more articulating lock sockets and one or more lock hinge sockets. Hinge arms can be pivotally coupled to the box, with a first hinge arm also being pivotally secured to an articulating hinge socket to accommodate pivotal displacement of the lid from the box, as well as pivotal displacement of the lid about a portion of the first hinge arm. A second hinge arm can be selectively removable from secure engagement with the lock hinge assembly. Further, a tamper resistant pin can extend through the upper head portion of the second hinge arm when the second hinge arm is engaged with the lock hinge socket so as to lock the second hinge arm to the lid, and thereby secure the lid at a closed position on the box.

A plug (1) for use with a counterbalancing system (3) of a cable-operated door (5). The plug (1) includes flange and collar portions (13,15), the flange portion (13) being connectable to a mounting component (7) of the counterbalancing system (3) in order to allow a torque transfer from a torsion spring (9) to the mounting component (7), and the collar portion (15) being configured for winding into a given end (17) of the torsion spring (9), the collar portion (15) having opposite first and second extremities (19,21), and an outer surface (23) extending between these extremities (19,21), the outer surface (23) of the collar portion (15) being provided with a plurality of threads (25) and a plurality of corresponding recesses (27) each being defined between a pair of adjacent threads (25), each recess (27) being configured for receiving therein a single coil segment (11a) of the torsion spring (9), and being further shaped and sized for preventing another coil segment (11b) of the torsion spring (9) from embarking onto said recess (27).

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

A sash guide for a hung window includes a plate having a first end and an opposite second end defining a longitudinal axis. The first end configured to mount to a side rail of a window sash and the second end having an outside surface spaced from the side rail in a transverse direction. The transverse direction being substantially orthogonal to the longitudinal axis. A cam block is disposed proximate the second end and between the plate and the side rail. An adjustment fastener is coupled to the cam block and configured to slide the cam block along the longitudinal axis such that the outside surface of the second end is adjustable along the transverse direction and in relation to the side rail.
