The invention relates to a sliding security gate that can be surface mounted to a wall or door trim. These surface-mounted sliding security gates can be installed across any doorway opening of one's home for the protection of babies/toddlers, pets, and disabled elderly. On one hand, the Reversible Surface-Mounted Sliding Security Gate can be used as a dual functioned component that can be opened from either the left-hand or right-hand side of any wall or door trim; on the other hand, the Reversible Surface-Mounted Sliding Security Gate can become reversible and secured to the wall/door trim at the bottom of the bracket to secure the gate into place in order to provide safety and security to the vulnerable population listed above. In addition, this sliding security gate also has an alarm attached to the end of the security gate so that when it opens, the alarm sounds.

Embodiments of the present disclosure provide a sliding door unit and an electronic device thereof. The sliding door unit includes a sliding door, setting on a base through a sliding component, and configured to slide relative to the base when receiving an external force; a first movement mechanism group placed at a first end of the sliding door; and a second movement mechanism group placed at a second end of the sliding door, and the first and second ends being two opposite ends. The first movement mechanism group and the second movement mechanism group move at a matching pace relative to the sliding door on the base when the sliding door is moved by the external force.

A pre-assembled fitting group for a window or door has a drive rod portion, which is movable in the rebate circumferential direction, a first control element, and a second control element which is arranged on a cross slide. The first and the second control elements cooperate and are coordinated with one another in such a way that a displacement of the first control element by the drive rod portion causes a displacement of the cross slide. A guide part that can be fixedly mounted on the sash, wherein the cross slide is at least partially movable relative to the guide part.

A semi-invisible combination of thermal insulating profiles of the lower part of sliding doors and windows which allows the unhindered passage of people and objects above the semi-invisible combination. The interior and exterior floor has co-planarity and uniformity while the invention permits unhindered passage of people and objects, is accessible by people with walking disabilities, has narrow width grooves, has a classy profile design, has high levels of waterproofing for the non-visible parts as well as high waterproofing against normal weather conditions.

The partition wall for commercial vehicles comprises at least one fixed plate (20) and a sliding door (10) able to slide with respect to said fixed wall (20), predisposed to separate the cockpit of the vehicle from the loading compartment. The sliding door (10) is provided, along the upper edge and along the bottom edge, with a plurality of sliding wheels (11, 12) predisposed to slide respectively on an upper guide (13) and on a lower guide (14) associated with the structure of the vehicle. The sliding wheels (11, 12) have a grooved profile predisposed to be coupled with a corresponding rail (19) of said guides (13, 14) having conjugated profile.

A sliding door unit has a mounting frame and an active door panel mounted in and capable of sliding relative to the mounting frame. The active door panel has a face including a panel portion and a glazing portion. The glazing portion comprises less than 65% of a surface area of the face.

A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A link type structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a first link member having a first end rotatably connected to the door and a second end connected to a link hinge, a second link member having a first end rotatably connected to the lower rail roller unit and a second end connected to the link hinge, and a spring provided on the link hinge. The spring is configured to supply elastic force such that one end of the first link member applies force to the door in a direction toward outside of the vehicle body.

Disclosed embodiments include a mounting apparatus for a sliding security barrier that includes unique security features that ensure the sliding security barrier is secure and does not suffer problems that exist with conventional security doors and windows. The sliding security barrier is configured to be implemented using tracks that are common to conventional sliding patio screen door or windows. Additional security features include a unique striker plate, a lift protector at a corner, adjustable top and/or bottom channel caps, an interlock, and a uniquely shaped lock. These features provide greater security at a lower cost because they use an existing sliding door or window sash and channels but provide a secure attachment that inhibits tampering and removal of the sliding screen barrier.

A structure for preventing opposite sliding doors from swaying is provided. The structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a guide roller unit fixedly connected to the lower rail, the guide roller unit including a guide roller rotatably connected to the lower rail, and a guide stopper fixedly connected to the door. The guide stopper includes a guide route formed inside the guide stopper and configured to serve as a rolling movement route for the guide roller, an exit/entrance portion formed at a first end of the guide route, and a stop portion formed at a second end of the guide route.
