A collapsible support frame assembly includes a support frame having two parallel sliding rails, a slide holder coupled to and movable along the sliding rails of the support frame, a constant force spring mounted between the support frame and the slide holder, and a locking device having a casing affixed to the support frame and a stop member pivotally mounted in an accommodation chamber inside the casing. When the support frame is turned from a vertical position to a horizontal position, the stop member is forced by the gravity thereof to bias out of the accommodation chamber relative to the casing and to stop against the slide holder, thereby locking the slide holder, facilitating packing and delivery.

Locking device, collapsible support frame assembly using the locking device

A collapsible lockable support frame assembly includes a support frame pivoted to the support arm of a stand and having two parallel sliding rails, a slide holder carrying a positioning member at the back side and coupled to and movable along the sliding rails of the support frame for holding a display device and a locking mechanism having a casing affixed to the support frame and an upper stop member and a lower stop member pivotally swingingly connected to the casing. When the support frame is turned from a vertical position to a horizontal position, the upper stop member and the lower stop member are forced by the gravity thereof to turn out of the casing so that the upper stop member stops the positioning member from outward displacement to lock the slide holder, facilitating packing and delivery and the lower stop member limits the inward displacement distance of the slide holder to prohibit the display device from hitting the support arm of the stand.

Collapsible lockable support frame assembly and locking mechanism used therein

An elevating device with a latching function including a supporting rack, a supporting seat, a constant force spring and a latching member. The supporting seat moves longitudinally with respect to the supporting rack, and has a shaft rod automatically recovering towards a central line thereof. An arrow-shaped positioning block is installed in a front end of the latching member, a positioning concave slot is formed at bottom ends of a first and a second guiding planes of the positioning block. When the shaft rod moves with the supporting seat in the supporting rack, the shaft rod moves downwardly along the first guiding plane to enter the positioning concave slot forming a latching status. When the shaft rod moves downwardly in the positioning concave slot, the shaft rod is released from the positioning concave slot forming a releasing status, and the shaft rod moves upwardly along the second guiding plane.
