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 system comprising an opening comprising a door or a window, wherein the opening comprises a door or a window frame is provided. The opening comprises at least one movable door panel or at least one movable window panel based on if the opening is the door or the window respectively. The system also comprises a deadbolt inbuilt in the door panel or the window panel, a guiding device and a mechanical moving mechanism, wherein the guiding device and the mechanical moving mechanism are both housed in a guiding device housing, a guide block, and an attachment mechanism.

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.

A frame assembly with sliding panels is described. The frame assembly includes a frame having an upper section opposite of a lower section. The lower section of the frame defines a first channel and a second channel. A first sliding panel includes a first lower edge. A first panel support is removably engaged to the first lower edge. The first panel support includes a first holding member that engages to the first lower edge. The first panel support slides in the first channel. A second sliding panel includes a second lower edge. A second panel support is removably engaged to the second lower edge. The second panel support includes a second holding member that engages to the second lower edge. The second panel support slides in the second channel.

The present invention provides an annular roller device for a sliding window/door, which is proposed as a roller device having a new structure wherein the roller device installed under a door sash can move a sliding window/door having heavy weight, and can maximize the open glass portion of the window/door by minimizing the height of the space required to install the roller device, thereby providing a more open view. The roller device has a structure in which, even when a rail installed on a window frame is not horizontal or the bottom portion of a window is not completely flat, all multiple rolling members, which constitute a ring-shaped rolling unit wound around a load-bearing plate (1220) comprising segment bodies (1221, 1222) rotatably connected to each other by a pivot pin (1225) extending therethrough, form contact points with the rail or the bottom portion, and thus each of the rolling members is prevented from being loaded with excessive weight.

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.
