Abstract:
There is provided a window and door frame for doors and windows built in a wall of a building. The window and door frame includes an extruded frame member. One face of the frame member is formed along a length direction thereof with a rail insertion groove. The window and door frame further includes a rail structure adapted to be combined with the rail insertion groove. The rail insertion groove is formed with engagement grooves, while the rail structure is formed with engagement projections. The rail structure is easily combined to and removed from the frame member by means of engagement between the engagement projections and the engagement grooves. Since the rail structure is attachable and detachable, a heavier door can be conveniently installed and the window and door frame can be easily cleaned up. Further, only a damaged rail structure can be replaced.
Abstract:
Movable partition systems include a vertical alignment structure including at least one roller element coupled to a portion of a movable partition and a ramp configured to abut against the at least one roller element to vertically align the portion of the movable partition to engage with a strike plate. Methods of vertically aligning the movable partition include coupling at least one vertical alignment structure to the movable partition including coupling at least one structural frame member to the movable partition and coupling the at least one roller element to the at least one structural frame member and installing at least one ramp to an overhead structure configured to abut the at least one roller element and vertically align a leading end of the movable partition.
Abstract:
A door suspension device includes a driving-side member, a hanger, an elastic member, and a first adjustment bolt. The hanger is configured so as to be displaceable in an opening/closing direction in conjunction with the driving-side member and supports a door. The elastic member allows relative displacements of the driving-side member and the hanger by elastically deforming in accordance with a load between the driving-side member and the hanger. The first adjustment bolt is a member for adjusting an initial value of a load that acts between the driving-side member and the hanger. The first adjustment bolt includes a male screw section to be fixed to the driving-side member, and a head which is arranged so that an axial force acting on the first adjustment bolt is received by an edge of the hanger.
Abstract:
A vehicle having a sliding door arranged behind a body pillar, a frame around the door opening closeable by the sliding door, a rail system provided in the region of the sliding door connected fixedly to the vehicle and having upper and lower guide rails, sliding carriages provided on the sliding door connected to the sliding door via a respective supporting arm and guided displaceably on the guide rails, and side impact protection in the region of the sliding door. At least one of the sliding carriages or supporting arms is provided with a stop. In the event of a side impact, in which the outer vehicle wall is deformed in the direction of the vehicle interior, an abutment connected to the vehicle wall comes to bear against the stop of the sliding carriage or of the supporting arm, and the position of the sliding door is thereby blocked.
