Embodiment Construction

[0013] refer to Figure 2 to Figure 19 , which is a retractable view of the adjustable support frame 100 of the present invention, Figure 2 to Figure 7 for schematic diagram, Figure 8 to Figure 13 is a side view, and Figure 14 to Figure 19 For top view. Adjustable support frame 100 is formed by cavity 104 of housing 102 of the device it supports, cavity 104 having a first inner end and a first outer end. The adjustable stand 100 can be used to elevate any device and is not limited to a projector.

[0014] refer to Figure 14 to Figure 19 , a ratchet housing 110 is placed in the cavity 104 of the housing 102, the ratchet housing 110 has a second inner end and a second outer end. The cavity 104 is longer than the ratchet housing 110 so that the ratchet housing 110 can move along a straight line in the cavity 104 . The ratchet 120 is placed in the ratchet housing 110 , and the ratchet 120 includes a protruding end 124 for allowing the ratchet 120 to be placed in the ratc...

Abstract

An adjustable supporter used for regulating the height of a device, which is composed of a casing and an empty cavity, consists of a ratchet casing able to move along a straight line in said empty cavity, a ratchet wheel in said ratchet casing and having teeth and projected end, and a pivoted detent.

Description

technical field [0001] The invention relates to a support frame, in particular to a support frame for tilting a projector. Background technique [0002] The support frame is generally used to adjust the height of at least one side of a device, for example, generally used to adjust the tilt angle of a projector. refer to figure 1 , figure 1 A known projector 10 includes a support frame 12 . When the projector 10 is placed on a surface 14 , the tilting angle of the projector 10 is raised by extending the supporting frame 12 . The projector 10 projects a light 18 to a screen 16 . In the known technology, the support frame 12 is adjusted so that the light 18 is projected to a proper position of the screen 16 . [0003] However, after the support frame 12 is extended, it is difficult to retract the support frame 12 into the projector 10 . Usually, both hands are used to complete this action, one hand disengages the ratchet from the support frame 12 , and the other hand push...
