A display device includes a display panel, a module housing accommodating the display panel and including a rear cover, a first moving plate connected to the display panel and positioned at a first side of the display panel, a second moving plate connected to the rear cover of the module housing and positioned at a second side of the display panel, a first driving member for pulling up and down the first moving plate, and a second driving member for pulling up and down the second moving plate.

Display stands are disclosed relating to the support of display devices such as televisions and computer monitors. The display stands described may include a pair of elongate telescoping vertical supports and a pair of elongate telescoping horizontal braces. The display stands may also include a variety of locking mechanisms that may be used to position and fix display devices in a preferred position for viewing.

A workstation for alternatively configuring a conventional desk for use while sitting and use while standing. The workstation includes an extendable column formed of multiple nested sections. The nested sections are configured to telescope such that the column can be extended. The workstation is configured to support a monitor and a tray. The extendable column contains a counter balance mechanism that is configured to resist collapsing of the column. A movement coupling mechanism is provided that it is such that motion of the first section relative to the second section is transmitted to the third section such that the third section moves a corresponding amount relative to the second section.

A dual-purpose stand and method for supporting photographic equipment is disclosed. The stand is able to be used as a monopod or a tripod. A retaining device is provided on the stand. The retaining device is selectively engaged to lock a leg assembly provided on the stand in a collapsed or closed position when the stand is to be used as a monopod. The retaining device is disengaged when the stand is to be used as a tripod. When the retaining device is disengaged, the stand will automatically become a tripod when placed on a support surface. The stand's legs will automatically move to an extended or open position when the stand is set down on the support surface and the legs will automatically move back to a collapsed or closed position when the stand is lifted from the support surface.

A lifting structure with adjustable bearing capacity is provided. The lifting structure comprises a main body, a carrier, a main constant force spring, and at least one auxiliary constant force spring. The main body comprises at least one slide and at least one actuating module. The main constant force spring connects to the carrier. The actuating module is able to be selectively switched between a non-actuating position and an actuating position. When the carrier is driven from the top of the lifting structure along the slide, at least the main constant force spring provides a constant force to the carrier.

The invention includes a display positioning assembly comprising a support, a display supported by the support, and a balance mechanism carried by the display and operatively connected to the support. The invention also includes an article for selectively exposing a display comprising a generally planar support surface having a first side and a second side opposite the first side. A balance mechanism operatively connected to a display may be positionable between a storage position proximate the first side of the generally planar support surface and an exposed position proximate the second side of the generally planar support surface. The invention also includes an assembly for arresting the free fall of an object. The assembly may comprise an outer slide in sliding or rolling engagement with an inner slide, and a brake comprising at least one pivot member may be coupled to the inner slide.
