Multi-position presentation easel
View Patent ↗The present invention is directed to a portable easel having a frame and a display panel movably coupled to the frame. The panel is movable with respect to the frame in a longitudinal direction, and the panel is rotatable with respect to the frame from a first predetermined angular position to a second predetermined angular position.
1. A portable easel, comprising:
a frame including a front leg member having a longitudinal axis extending from a top end to a bottom end;
a display panel movably coupled to the frame, wherein the panel is movable with respect to the frame in a longitudinal direction, and the panel is rotatable with respect to the frame;
a positioning assembly including a locking mechanism for locking the angular position of the display panel in one of a plurality of discrete predetermined positions, the discrete predetermined positions including at least a first predetermined angular position and a second predetermined angular position; and
at least one adjustable rear leg assembly connected to the frame to support the frame in a substantially upright positions;
wherein the positioning assembly is coupled to the frame for positioning the panel with respect to the frame, the positioning assembly including,
a stationary plate fixedly connected to the frame; and
a position cart movably coupled to the stationary plate, the position cart including,
a slide plate operatively connected to the stationary plate and movable with respect thereto in the longitudinal direction; and
a pivot plate connected to the panel and operatively connected to the slide plate and rotatable with respect to the slide plate to position the panel with respect to the frame.
2. The easel of claim 1 , wherein the first predetermined angular position is separated from the second predetermined angular position by at least an angle of about 90 degrees.
3. The easel of claim 1 , wherein the panel is in a substantially portrait position in the first predetermined position and the panel is in a substantially landscape position in the second predetermined position.
4. The easel of claim 1 , wherein the locking mechanism lockingly positions at least one of the slide plate and pivot plate in a predetermined position.
5. The easel of claim 4 , wherein the locking mechanism comprises at least one ball detent mechanism connected to at least one of the stationary plate, sliding plate, and pivot plate, to lockingly position the plates with respect to each other in at least one direction.
6. The easel of claim 4 , wherein the panel is manually rotatable from the first position to the second position without adjusting the locking mechanism.
7. The easel of claim 6 , wherein the panel automatically locks in the second predetermined angular position when the panel is moved from the first predetermined angular position to the second predetermined angular position.
8. The easel of claim 1 , further comprising at least one wheel mounted on either the front leg or rear leg assembly.
9. The easel of claim 1 , further comprising an accessory tray hingedly connected to the frame and pivotable with respect thereto.
10. The easel of claim 1 , wherein the panel further comprises at least one clip to hold a display object.
11. The easel of claim 1 , further comprising a pneumatic cylinder operatively connected to the display panel for facilitating movement of the panel in the longitudinal direction.
12. The easel of claim 1 , wherein the display panel comprises a dry-erase board.
13. A portable easel, comprising:
a frame including a front leg member having a longitudinal axis extending from a top end to a bottom end;
a display panel movably coupled to the frame, wherein the panel is movable with respect to the frame in a longitudinal direction from at least a first predetermined vertical position to at least a second predetermined vertical position, and the panel is rotatable with respect to the frame from at least a first predetermined angular position to at least a second predetermined angular position;
a pneumatic cylinder operatively connected to the display panel for facilitating movement of the panel in the longitudinal direction; and
at least one adjustable rear leg assembly connected to the frame to support the frame in a substantially upright position.
14. A portable easel, comprising:
front and rear easel support members;
a stationary plate mounted on the front support member;
a slide plate slideably engaging said stationary plate such that the slide plate may translate along a translation axis;
a pivot plate mounted on the slide plate, said pivot plate rotatable about a second axis at least substantially perpendicular to said translation axis; and a display panel mounted on said pivot plate whereby the display panel may be translated and rotated with respect o the easel support members.
15. The portable easel according to claim 14 , further comprising detent means disposed on said slide plate and cooperating with said pivot plate to provide a plurality of lockable predetermined rotational positions for said display panel.
16. The portable easel according to claim 14 , further comprising detent means disposed on said slide plate and cooperating with said stationary plate to provide a plurality of locatable predetermined translational positions for said display panel.
17. The easel of claim 1 , wherein the locking mechanism includes at least one ball detent mechanism to lockingly position the display panel in one of the discrete predetermined positions.
18. The easel of claim 1 , wherein the display panel is manually rotatable from the first predetermined angular position to the second predetermined angular position without adjusting the locking mechanism.
19. The easel of claim 1 , wherein the display panel automatically locks in the second predetermined angular position when the panel is moved from the first predetermined angular position to the second predetermined angular position.
20. A portable easel, comprising:
a frame including a front leg member having a longitudinal axis extending from a top end to a bottom end;
a display panel movably coupled to the frame, wherein the panel is movable with respect to the frame in a longitudinal direction, and the panel is rotatable with respect to the frame;
a positioning assembly including a locking mechanism for locking the angular position of the display panel in one of a plurality of discrete predetermined positions, the discrete predetermined positions including at least a first predetermined angular position and a second predetermined angular position;
at least one adjustable rear leg assembly connected to the frame to support the frame in a substantially upright position; and
a pneumatic cylinder operatively connected to the display panel for facilitating movement of the panel in the longitudinal direction.
