Abstract
The invention provides a projector arrangement (1) in which an objective cover unit (6) for covering a light exit portion or surface (4e) of an objective unit (4) is adapted to serve as a support or bearing (8) for a projector unit (3) of a projector arrangement (1) in an operation mode. Additionally or alternatively, said projector arrangement (1) comprises a surface region (2a) to be rested on in an operation or projection mode, so as to realize distinct positions and/or orientations for the projection.
Claims18
Projector arrangement, comprising:
- a projector unit (3) having an objective unit (4) for optically projecting images, in particular on an external screen (20), and
- an objective cover unit (6) for covering a light exit portion (4e) or light exit surface (4e) of said objective unit (4) in a standby, pause, non-projecting mode and/or non-operation mode of said projector arrangement (1),
- characterized in
- that said objective cover unit (6) is adapted to serve and/or to function as a support or bearing unit (8) for supporting said projector unit (3), in particular on an external operation surface (100), in an operation mode of said projector arrangement (1).
Projector arrangement,
- comprising a projector unit (3) having an objective unit (4) for optically projecting images, in particular on an external screen (20),
- characterized in
- that a surface region (2a) is provided having a plurality of locations (P2, P3, P4) and/or portions (P2, P3, P4) being adapted for directly or indirectly resting on, in particular an external operation or working surface (100), in an operation mode or projecting mode of said projector arrangement (1) and
- that each of said locations (P2, P3, P4) and/or portions (P2, P3, P4) of or on said projector unit (3) are chosen to be assigned to and/or to realize a distinct position and/or orientation of said projector arrangement (1) and in particular of its objective unit (4) in said operation mode or projecting mode of said projector arrangement (1).
Projector arrangement according to any one of the preceding claims,
- wherein said projector unit (3) comprises a base portion (2) having a surface (2a), in particular as said surface region (2a) of said projector unit, at least a part of which being continuously and/or smoothly curved in an at least local convex manner,
- in particular so as to realize said plurality of said locations/portions (P2, P3, P4), positions/orientations and/or projection angles (α2, α3, α4) or inclination angles (α2, α3, α4), in particular on its surface (2a), and/or
- in particular so as to enable in said operation mode of said projector arrangement (1) a resting or supporting of said projector unit (3) on said support or bearing unit (8).
Projector arrangement according to any one of the preceding claims,
- wherein said objective cover unit (6) is formed as a detachable cap for said objective unit (4).
Projector arrangement according to any one of the preceding claims,
- wherein said objective cover unit (6) comprises:
- a first or inner base surface (6o) adapted to face said light exit portion (4e) or light exit surface (4e) of said objective unit (4) in said standby, pause, non-projecting and/or non-operating mode and to face said projector unit (3) and in particular said base portion (2) further in particular ist surface (2a) in said operation mode of said projector arrangement (1), and
- a second or outer base surface (6b) situated opposite said first or inner base surface (6i) and therefore situated opposite from said light exit portion or said light exit surface (4e) of said objective unit (4) in said standby, pause, non-projecting, and/or non-operating mode and opposite said base portion (2) and/or said surface (2a) thereof in said operation mode and which is in particular adapted to face and rest on said external operating surface (100) in said operation mode.
Projector arrangement according to any one of the preceding claims,
- wherein said objective cover unit (6) as said support or bearing unit (8) and in particular its rim portion (6r) and/or said abutment surfaces (6u) and/or said projector unit (6r) and in particular its base portion (2) are formed and adapted to realized one or an arbitrary combination or plurality of the following aspects:
- cooperation and/or engaging of respective shapes and/or surfaces,
- frictional interaction forces between each other,
- stable and/or equilibrated support of said projector unit.
Projector arrangement according to any one of the preceding claims,
- wherein said projector unit (3) and in particular its base portion (2) have a shape and/or a mass distribution so as to ensure to be supported by said support or bearing unit (8) in mass or gravitational equilibrium.
Projector arrangement according to any one of the preceding claims,
- wherein said objective cover unit (6) and in particular its rim portion (6r) comprise position holding or fixing elements for ensuring an essentially fixed positioning of the supported and rested projector unit (3) in said operation mode.
