A door system has a door leaf configured to be moved between closed and opened positions while carrying out a door leaf movement. The door leaf is moved in the vehicle transverse direction across a door leaf movement distance in the vehicle transverse direction, a door seal, disposed underneath a lower edge of the door leaf closing off the door leaf towards the bottom, and extends along the lower edge. The door seal is arranged such that the door seal, when the door leaf movement is carried out, undergoes a door seal movement and is moved in the process in the vehicle transverse direction across a door seal movement distance in the vehicle transverse direction. An arrangement of the door leaf and door seal that ensures that the door seal movement distance in the vehicle transverse direction is smaller than the door leaf movement distance in the vehicle transverse direction.

A pneumatic door closer includes a rotary energy-storing mechanism including a housing and a driving mechanism. The driving mechanism includes a cylinder, a second piston assembly and a sealing element, the sealing element is in an air tight connection with the cylinder and the second piston assembly, to form a closed space filled with high pressure gas in the cylinder. The second piston assembly drives the closed space into a first air chamber and a second air chamber in communication with each other. The driving mechanism also includes a first piston assembly connected to the second piston assembly. The pneumatic door closer also includes a transmission mechanism having one end received in the housing and another end connected to the door frame.

An isolator comprises a manipulation chamber isolated from the external atmosphere, a door for opening and closing a portal formed on the manipulation chamber, a linear guide mechanism for guiding a linear motion of a front-side edge of the door along the portal, and a rotation guide mechanism defining a rotation of the door about an axis coinciding with the front-side edge. The door is closed by positioning the front-side edge at the front side of the manipulation chamber, and the door is opened inward into the manipulation chamber by moving the front-side edge toward the back side while rotating the door about the front-side edge.

A refrigerator includes: a cabinet; a door rotatably connected to the cabinet by a hinge; and a door opening device for opening the door. The door opening device includes a driving motor and a push member configured to move in the forward/backward direction. The push member includes a first end portion positioned close to the front surface of the cabinet and a second end portion positioned on the opposite side of the first end portion. The cabinet includes a cabinet side wall positioned close to the hinge. The door includes a door side wall positioned close to the hinge. When the door is closed, the horizontal distance between the first end portion and the cabinet side wall or the door side wall is smaller than the horizontal distance between the second end portion and the cabinet side wall or the door side wall.

The present invention relates to a door operator system (1) for opening and closing an opening (2), comprising a drive unit (10), a door frame (3) and a door (8), wherein the drive unit (10) is mounted to the door (8) and adapted to move the door (8) between an open (O) and closed position (C), the door frame (3) comprise at least a first frame section (4) adapted to be mounted at a first side (5) of the opening (2), a second frame section (6) adapted to be mounted at a second side (7) of the opening (2), a first track unit (31) moveably connected to the first frame section (4), and a second track unit (32) moveably connected to the second frame section (6), the door (8) is at a first side moveably connected to the first track unit (31) and at a second side moveably connected to the second track unit (32), wherein the door frame (3) is adapted to move the door (8) between the closed position (C) and an intermediate position (I) and to guide the door (8) between the intermediate position (I) and the open position (O).

A window regulator including a panel and a guide rail. The panel may define a speaker aperture that may be configured to receive at least a portion of the speaker. The guide rail may be integrally formed to the panel and configured to carry a slider. The slider may be configured to move along the guide rail to move the window between a first position and a second position. The guide rail may include an aperture-region portion that may extend across the speaker aperture in a first direction. The aperture-region portion may include a first sidewall and a second sidewall that may each extend in a second direction that may be substantially orthogonal to the first direction.

A door hinge apparatus of a vehicle may include a main bracket provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and having slide slots formed on upper and lower plates, respectively, a slide hinge bracket engaged to the slide slots to be slidable along the slide slots of the main bracket by a link mechanism, and a door hinge bracket Provided on the end portion of the door and pivotally connected to an external end portion of the slide hinge bracket through a hinge shaft.

A wall panel system may include a bottom drop seal assembly that maintains a constant force relative to a floor portion of an environment through a damper. The wall panel system may include an automatic top seal assembly that seals a gap between the movable wall panel system and a ceiling of the environment. The moveable wall panel system may include multiple panels and a plurality of seals positioned between adjacent panels to seal a gap between the adjacent panels.

A vacuum adiabatic body includes a conductive resistance sheet which blocks heat conduction between plate members, and a sealing frame which covers the conductive resistance sheet. The sealing frame includes a side surface part, an outer surface part which is bent and extends from a side of the side surface part, and an inner surface part which is bent and extends from the other side of the side surface part. The sealing frame is provided as a configuration of a concave groove in which the width between the outer surface part and the inner surface part is smaller than the width of the side surface part. According to the present invention, a peripheral portion of the vacuum adiabatic body can be stably maintained.

An enclosed space is provided that includes a ceiling, base structure, a plurality of walls, at least one sliding door, a controller, an input air fan and an air outlet. The height and inclination of the base structure are adjustable. The base structure has a first profile; a second profile; and one or more bolts for arranging a tilting angle between the first profile and the second profile. At least one of the walls include an opening for accessing the enclosed space. The door includes two parallel glass panels. The input air fan includes an air filter and the air outlet includes a flow meter configured to provide flow information to the controller.
