Improvements to movable closure systems which aid installability and reliability of said systems can include wheels running along the top and bottom of individual slidable elements, the wheels oriented horizontally and disposed within a track configured for receiving the horizontal wheels. The horizontal wheels reduce the vertical profile of the track-engaging portions of the slidable elements, enabling more of the slidable element to be used for glass or other aesthetically-preferable transparent materials. A track leveling system enables installers to more easily deploy and properly tune the system between floors and casings which are not perfectly flush. A compression jamb permits closure of the system via slidable elements pressing into the jamb to deflect it in order to better seal the closure comprised of the individual slidable elements. A durable hinge mechanism permits the sliding elements to rotate in order to stack the sliding elements at one end of the system.

[Problem] A drive unit (10) for driving, via a first and second geared cable (8, 9), a first and second member to be driven (sun roof and shade) provided to an opening part formed on the secured roof of a vehicle, wherein while being able to switch between a state in which the power from a motor (18) is transferred to both the first and second members to be driven and a state in which the power is selectively transferred to the first or second member to be driven, the member to be driven, in which the transfer of the power from the motor (18) is blocked, is prevented from moving during an impact when the vehicle collides in the selective transfer state. [Solution] The output path of the motor (18) is divided into a first and second output shaft (22, 42). Moreover, a first and second electromagnetic clutch (24, 44) for switching between connecting/disconnecting a first and second pinion gear (23, 43) to/from the first and second output shafts (22, 42) is provided, and each pinion gear (23, 43) is secured to a frame (3) so as to not be able to rotate when disconnecting from the clutches (24, 44).

The present invention discloses a refrigerator and relates to the technical field of refrigerators. The refrigerator is invented to settle problems, such as increased external space occupied by a refrigerator when its secondary door is opened, increased difficulty in fetching goods in the refrigerator, and heavy loss of cooling capacity resulted from the full opening of an opening. The inventive refrigerator comprises a main door; an opening is formed on a door body of the main door; a guide rail is provided at an edge of the opening, and a secondary door is fitted on the guide rail; and the secondary door is connected with a driving mechanism which can drive the secondary door to slide along the guide rail, and as the secondary door slides along the guide rail, the secondary door can enclose or open the opening. The refrigerator of the present invention is used for preserving and freezing foods.

A slider assembly for adjusting glass in frameless side window regulators includes a slider base, a glass retainer, and a back plate, with the glass retainer connected to the slider base and the back plate supporting both, ensuring the assembly is securely attached to the glass. A cam, pre-assembled on the slider base, features multiple serrations that engage with the slider base in a pre-assembled condition to support the bottom edge of the glass. A spring tab, integrally connected to the glass retainer, holds the cam on the slider base using a frictional force. Upon operation, the spring tab releases this frictional force, pushing the cam towards the slider base, and allows the cam to rotate. This rotation facilitates precise and secure positioning of the glass during adjustments.
