The carriage body and the support frame are mutually engaged by a hinge that allows reciprocal rotation.

A sliding door system for a vehicle includes a sliding door including an upper edge and a lower edge; a lower roller coupled to the lower edge of the sliding door, the lower roller defining a groove; a lower guide coupled to the lower edge of the sliding door adjacent to the lower roller, the lower guide defining a groove; an upper roller coupled to the upper edge of the sliding door, the upper roller defining a groove; an upper guide coupled to the upper edge of the sliding door adjacent to the upper roller, the upper guide defining a groove; a lower rail affixed to a frame of the vehicle and disposed vertically below the lower edge of the sliding door, wherein the groove of the lower roller is engaged with the lower rail and wherein the groove of the lower guide partially surrounds the lower rail; and an upper rail affixed to a frame of the vehicle and disposed vertically above the upper edge of the sliding door, wherein the groove of the upper roller is engaged with the upper rail and wherein the groove of the upper guide partially surrounds the upper rail.

A sliding door roller assembly includes a roller housing being at least partially disposed within an outer housing moveable relative to the roller housing and at least one roller wheel in a direction perpendicular to a rotational axis of the at least one roller wheel. At least one resilient member is positioned at an end of the outer housing, and includes a fixed termination section coupled to an end member of the outer housing, a compliant section extending from the fixed termination section, a curved engagement section, and a resilient section between the compliant section and the curved engagement section and pivotable about the compliant section. The at least one resilient member is flexible from a first position to a second position when the curved engagement section mates with an inner surface of a slot defining a bottom edge of a panel secured to the outer housing to provide a holding force between the resilient member and the inner surface of the slot.

A carriage has a wing part which can be fastened to a wing and a roller part which is displaceable on a running rail. The wing part is displaceable in a positively controlled manner transversely to the running rail. The roller part has a height-adjustable roller upper part. The vertical adjustability of the roller upper part with respect to a roller holder of the roller part is achieved by means of an adjusting element which is displaceable by means of an adjusting screw. The adjusting element is preferably supported with at least one adjusting element bevel on a pendulum axle of the running roller holder and/or on an upper part bevel of the roller upper part.

A sliding door roller for a sliding door includes a slide disposed within a housing and a truck assembly disposed within the slide. When the truck assembly is retracted within the slide, the truck assembly and the slide are at least partially engaged to as to restrict or prevent the truck assembly from dropping out of the housing and rotating within the housing. The truck assembly being disengaged from the slide via an adjustment fastener to move the truck assembly towards and extended position relative to the housing.

The present disclosure relates to a pulley device, a sliding door, and a sliding window. The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.

The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.

A frame structure includes a frame body, a corner connector and roller mechanism arranged in a splice of adjacent side frames at a bottom of the frame body, and a guide mechanism clamped to a top of the frame body. A glass positioning slot is disposed on a first side of an inner side wall of a side frame of the frame body. A mounting slot is disposed on a first side of an outer side wall of the side frame of the frame body and used for fixing the guide mechanism or the corner connector and roller mechanism. The glass positioning slot is adjacent to the mounting slot along a lengthwise direction of the first side of the inner side wall. A sliding door is further provided.
