Claims
- 1. A foldable, height adjustable stage, comprising:
- (a) first and second main support legs interconnected to form a base frame;
- (b) first and second stage surface members;
- (c) means hingeably connecting said first and second stage surface members to said base frame for movement between a storage position wherein said stage surface members are generally vertically disposed above said base frame, and an operable position in which said stage surface members are generally horizontally disposed to define a continuous stage surface;
- (d) first and second outer leg means connected to said first and second stage surface members respectively, remote from said base frame for supporting said stage surface members when in their operable positions;
- (e) means for adjusting the length of said first and second outer leg means;
- (f) first and second auxiliary support leg means mounted respectively to said first and second stage surface members adjacent the hingeable connection thereof to said base frame;
- (g) means for adjusting said auxiliary support leg means between a storage position and an operable position in which said support legs extend outward from said stage surface members further than said main support legs for supporting said stage in an elevated position; and
- (h) said auxiliary support leg means including floor or surface contacting portions which extend, when said stage is in an elevated position, towards the center of said stage beneath the hingeable connection of said stage surface members to said base frame, so as to further support the center portion of said stage in its elevated position.
- 2. A stage according to claim 1 wherein said auxiliary support leg means have curved portions adjacent the extended floor or surface contacting portions, for facilitating rocking or pivoting motion of the stage thereabout during stage setup.
- 3. A stage according to claim 1 wherein said first and second auxiliary leg means each comprise a pair of legs pivotally connected to the underside of their respective stage surface members for lateral folding into their storage position.
- 4. A stage according to claim 3 further including locating tabs positioned on said auxiliary support leg means and base frame and aligned with one another for abutment when the auxiliary support leg means are in their operable position, so as to laterally locate and stabilize the auxiliary support leg means.
- 5. A stage according to claim 2 wherein said first and second auxiliary support legs comprise upper leg parts connected to said stage surface members having lower foot portions telescopically engaging said upper part, and means for telescopically adjusting said foot portions with respect to said upper portions for providing further height adjustments for said stage.
- 6. A stage according to claim 1 wherein said first and second auxiliary leg means each comprise a pair of legs each having modified U-shaped configuration with upright portions pivotally connected to the underside of their respective stage surface members to permit lateral folding to a storage position, a floor or surface contacting portion extending from beneath the upright portions towards the center of the stage for support thereof when the stage is in its elevated position, and a curved portion extending from the floor contact portion back to one of said upright portions, said curved portions facilitating rocking or pivoting motion of the stage thereabout during stage setup.
