Abstract
Abstract A foldable sunshade attachment is adapted to be removably mounted to a well-known type of collapsible lawn chair. It mounts releasably but rigidly to an upper cross member of the back member of the chair, as by a strap-type bracket mount secured to said cross member; and said mount adjustably carries an upright column including an elongated first tubular rod component of the attachment. A second rod component is adjustably secured to the first rod component and carries at its end a sunshade. The attachment features multiple adjustments of the rod structure of the improvement, such as, in addition to a tilt of the latter''s shade, to permit (a) a sliding axial elongation of the rod structure as a whole, (b) an angular adjusting rotation of a rod component about its own axis, and (c) a pivotal swing of the rod structure in a vertical plane relative to the chair.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
224 words
A shade or like attachment for an article of furniture having a horizontally extending cross part, comprising a column unit supporting a shade or like member at an upper end of said unit, said unit including an elongated rod component, bracket means for rigidly but releasably attaching said column unit in a vertically extending relation of its said rod component to and above said cross part, and means including a clamp device providing for adjustments of the position of said unit''s rod component longitudinally in the direction of its length and angularly about its own axis, said device including a sleeve unit telescoped on said rod component and rotatable about the axis thereof in a vertically spaced relation to said part, said sleeve unit comprising a rotatable annular clamP element having an external surface eccentric of said axis which, upon rotation of the sleeve unit and element about the axis, radially and externally engages against a portion of said furniture cross part and frictionally but releasably clamps said rod component in the latter''s said longitudinally or angularly adjusted position relative to said cross part, said column unit having a further elongated rod component, and means pivotally articulating said rod components to one another for an adjusting swing of said further elongated rod component in a plane including the axes of both of said components.
Claim 2
Dependent Claim
224 words
A shade or like attachment for an article of furniture having a horizontally extending cross part, comprising a column unit supporting a shade or like member at an upper end of said unit, said unit including an elongated rod component, bracket means for rigidly but releasably attaching said column unit in a vertically extending relation of its said rod component to and above said cross part, and means including a clamp device providing for adjustments of the position of said unit''s rod component longitudinally in the direction of its length and angularly about its own axis, said device including a sleeve unit telescoped on said rod component and rotatable about the axis thereof in a vertically spaced relation to said part, said sleeve unit comprising a rotatable annular clamP element having an external surface eccentric of said axis which, upon rotation of the sleeve unit and element about the axis, radially and externally engages against a portion of said furniture cross part and frictionally but releasably clamps said rod component in the latter''s said longitudinally or angularly adjusted position relative to said cross part, said column unit having a further elongated rod component, and means pivotally articulating said rod components to one another for an adjusting swing of said further elongated rod component in a plane including the axes of both of said components.
Claim 3
Dependent Claim
224 words
A shade or like attachment for an article of furniture having a horizontally extending cross part, comprising a column unit supporting a shade or like member at an upper end of said unit, said unit including an elongated rod component, bracket means for rigidly but releasably attaching said column unit in a vertically extending relation of its said rod component to and above said cross part, and means including a clamp device providing for adjustments of the position of said unit''s rod component longitudinally in the direction of its length and angularly about its own axis, said device including a sleeve unit telescoped on said rod component and rotatable about the axis thereof in a vertically spaced relation to said part, said sleeve unit comprising a rotatable annular clamP element having an external surface eccentric of said axis which, upon rotation of the sleeve unit and element about the axis, radially and externally engages against a portion of said furniture cross part and frictionally but releasably clamps said rod component in the latter''s said longitudinally or angularly adjusted position relative to said cross part, said column unit having a further elongated rod component, and means pivotally articulating said rod components to one another for an adjusting swing of said further elongated rod component in a plane including the axes of both of said components.
Claim 4
Dependent Claim
224 words
A shade or like attachment for an article of furniture having a horizontally extending cross part, comprising a column unit supporting a shade or like member at an upper end of said unit, said unit including an elongated rod component, bracket means for rigidly but releasably attaching said column unit in a vertically extending relation of its said rod component to and above said cross part, and means including a clamp device providing for adjustments of the position of said unit''s rod component longitudinally in the direction of its length and angularly about its own axis, said device including a sleeve unit telescoped on said rod component and rotatable about the axis thereof in a vertically spaced relation to said part, said sleeve unit comprising a rotatable annular clamP element having an external surface eccentric of said axis which, upon rotation of the sleeve unit and element about the axis, radially and externally engages against a portion of said furniture cross part and frictionally but releasably clamps said rod component in the latter''s said longitudinally or angularly adjusted position relative to said cross part, said column unit having a further elongated rod component, and means pivotally articulating said rod components to one another for an adjusting swing of said further elongated rod component in a plane including the axes of both of said components.
Claim 5
Dependent Claim
35 words
The attachment of claim 1, in which said last-named means includes means for clamping said rod components together as adjusted in said plane, and for individually adjusting said further component angularly about its own axis.
Claim 6
Dependent Claim
28 words
The attachment of claim 1, in which said element''s eccentric surface is inwardly concave for mating engagement with said cross part in the wedging action of the element.
Claim 7
Dependent Claim
48 words
The attachment of claiim 1, in which said element''s eccentric surface is inwardly concave for mating engagement with said cross part in the wedging action of the element, said bracket means encircling said cross part and having a pair of flexible arms between which said clamp element operates.
Claim 8
Dependent Claim
48 words
The attachment of claiim 1, in which said element''s eccentric surface is inwardly concave for mating engagement with said cross part in the wedging action of the element, said bracket means encircling said cross part and having a pair of flexible arms between which said clamp element operates.
Claim 9
Dependent Claim
84 words
The attachment of claim 1, in which said element''s eccentric surface is inwardly concave for mating engagement with said cross part in the wedging action of the element, said bracket means encircling said cross part and having a pair of flexible arms between which said clamp element operates, said element having portions engaging the respective arms of said bracket means to draw the arms toward one another into compressive axial engagement with said clamp element as the latter acts wedgingly upon said cross part.
Claim 10
Dependent Claim
41 words
The attachment of claim 1, in which said sleeve unit further comprises a manipulating sleeve in externally telescoped relation to said eccentric annular clamp element and rotatable concurrently with the latter in said releasable frictional clamping of the first-named rod component.
