The present invention relates to a support frame, and more particularly to a screen support frame.
A support frame for supporting a screen is known, such as Taiwan Utility Model M599368. The known support frame comprises a base, a vertical pole, a connecting member, and a locking member. The vertical pole is mounted on the base and is connected by the connecting member to the locking member for being fixed, so that the support frame can be securely stood. A carrying member is provided on the vertical pole to receive a screen to position thereon so as to make a support frame for screens.
However, most of known screen support frames are structured to only allow adjustment in respect of a vertical position of the screen by means of a retaining member, such as a pin, a bolt, or a spring, provided on the vertical pole. Yet, some of the retaining means must be operated with an external tool for making such an adjustment. Further, most of the screen support frames are only adjustable for the vertical position of the screen. If a user attempts to make rotation for a different application or to otherwise adjust to a different angular position, there will be a situation that the known support frames do not support for such adjustment.
In view of the above-discussed problems of the known screen support frame, an objective of the present invention is to provide a screen support frame.
To achieve the above objective, the present invention provides a screen support frame, which comprises:
a screen support frame, wherein the screen support frame comprises a base and a supporting member, the supporting member comprising a supporting member mounting portion and a supporting member rotating portion, the supporting member mounting portion having one end mounted to the base, the supporting member mounting portion having an opposite end on which a protrusion and a rotation stop are formed, the supporting member rotating portion comprising a receiving hole and receptacle formed therein, wherein the protrusion of the supporting member mounting portion is disposed in the receiving hole of the supporting member rotating portion and the rotation stop of the supporting member mounting portion is disposed in the receptacle of the supporting member rotating portion, so that the supporting member provides an effect of rotating; the supporting member rotating portion comprises a pair of rails and a longitudinally movable member arranged between the rails, the longitudinally movable member having a side surface from which a frontward projection arm extends outwards, the longitudinally movable member having an opposite side that is provided with a friction member and a plurality of elastic member receiving troughs, an enclosure being provided to enclose the supporting member rotating portion, a plurality of elastic members being arranged in an interior of the enclosure, the elastic members being respectively disposed in the elastic member receiving troughs of the longitudinally movable member to each provide a spring force, the enclosure being provided with a friction track, the friction track being arranged for contact engagement with the friction member of the longitudinally movable member to increase a frictional force.
Preferably, the longitudinally movable member is provided with a friction adjusting member. The friction adjusting member is arranged to push against the friction member to make adjustment of the frictional force between the friction member and the friction track for increasing or decreasing the frictional force.
A screen fixing portion is provided, and the screen fixing portion is mounted to the frontward projection arm of the longitudinally movable member of the supporting member rotating portion. The screen fixing portion is provided with a group of symmetric elastic members and a group of symmetric friction members, wherein the symmetric elastic members of the screen fixing portion provide spring forces and the symmetric friction members of the screen fixing portion provide frictional forces, both combined providing the screen fixing portion with an effect of adjusting an elevation angle of a screen attached thereto.
Preferably, the screen fixing portion is provided with a rotating disc, and the rotating disc allows the screen fixing portion to do rotation in a clock like fashion, so as to provide the screen fixing portion with an effect of adjusting sideway rotating angle.
Preferably, the supporting member is provided with a front cover and a rear cover. The front cover and the rear cover are arranged to mate each other to enclose around and house the supporting member therein.
In the present invention, the supporting member is structured such that the supporting member rotating portion is formed with the receptacle, while the supporting member mounting portion is provided with the rotation stop, so that the present invention achieves an effect of rotation. Further, in the present invention, the supporting member is structured to include the longitudinally movable member, and the longitudinally movable member applies a frictional force with respect to the friction member and the friction track of the enclosure by means of a spring force applied from the plurality of elastic members, so that the present invention achieves an effect of longitudinal movability. Further, the screen fixing portion is structured to include the symmetric elastic members and the symmetric friction members, and an effect of adjusting the elevational angle of the screen fixing portion is achieved. Further, the screen fixing portion is structured to include the rotating disc, and an effect of adjusting a sideway rotating angle of the screen fixing portion is achieved. In summary of the description provided above, the present invention may provide effects of adjustment of vertical position, elevational angle, sideway rotating angle, and angle of rotation.
