Abstract

A lampshade adapted to be interconvertible between an assembled configuration having a first volume and a knockdown configuration having a second, smaller volume comprises lampshade segments connected to rotational elements. Slotting means on preselected rotational elements position the connecting members to assume predetermined positions with respect to the common axis, where the rotational elements are locked in place. Methods for use of the lampshade in knockdown shipping, and kits containing the lampshade and instructional materials are also taught.

Claims

1. A lampshade adapted to be interconvertible between an assembled configuration having a first volume and a knock-down configuration having a second, smaller volume;

said lampshade comprising in combination;

at least two lampshade segments;

a predetermined number of connecting members;

a predetermined number of rotational elements;

said rotational elements adapted to be positioned within one another;

said rotational elements having a common axis of rotation;

said connecting members adapted for connecting a preselected said rotational element with a preselected said lampshade segment;

assembly means adapted to permit rotational movement of at least said rotational elements and to maintain at least said rotational elements in a substantially inseparable assembly;

slotting means on preselected said rotational elements adapted to slottingly fit said connecting members;

said slotting means further adapted to position said connecting members to assume predetermined angular positions with respect to said common axis; and

,

locking means adapted for lockingly positioning said connecting members in said predetermined angular positions.

2. The lampshade according to claim 1, wherein said assembly means comprise spring means.

3. The lampshade according to claim 2, wherein said spring means are disposed on said common axis and adapted to urge said rotational elements and said locking means apart on said common axis;

said spring means further adapted to permit rotational movement of said locking means and said rotational elements; and

, said spring means further adapted to maintain said rotational elements and said locking means in a substantially inseparable assembly.

4. The lampshade according to claim 1, further comprising mounting means for mounting said lampshade on a lamp.

5. The lampshade according to claim 1, wherein said connecting members are attached to said preselected rotational elements and said preselected lampshade segments by attachment means.

6. The lampshade according to claim 5, wherein said attachment means is selected from the group consisting of welding, soldering, gluing, press fitting, tying, wiring, bolting, crimping, and manufacture as a single unit.

7. The lampshade according to claim 1, further comprising clipping means adapted for dipping together preselected borders of said lampshade segments.

8. The lampshade according to claim 1, wherein said segments are segments of a generally conical shape.

9. The lampshade according to claim 1, wherein said segments are segments of a generally cylindrical shape.

10. The lampshade according to claim 1, wherein said segments are segments of a generally hemispherical shape.

11. The lampshade according to claim 1, wherein said segments have a generally rectangular shape.

16. A kit for shipping a lampshade adapted for shipping in a knock-down state, said kit comprising:

(a) the lampshade of claim 1;

(b) packaging materials; and

,

(c) at least one device for explaining the assembly of said lampshade.

17. A kit according to claim 16, wherein said instructional device is at least one device selected from the group consisting of printed materials, CD disks, magnetic data storage disks, and videotapes.

12. A generally conical lampshade adapted to be interconvertible between an assembled configuration having a first volume and a knock-down configuration having a second, smaller volume;

said lampshade comprising in combination;

three lampshade segments;

three connecting members;

three rotational elements;

said rotational elements adapted to fit telescopically into each other;

said rotational elements having a common axis of rotation;

each connecting member having a first end and a second end;

each said first end adapted for attachment by attachment means to a preselected lampshade segment;

each said second end adapted for attachment by attachment means to a preselected said rotational element;

slotting means on preselected rotational elements adapted to allow said connecting members to lie in a single plane;

said slotting means further adapted to position said connecting members to assume predetermined angular positions with respect to said common axis;

locking means disposed on said common axis adapted for arresting movement of said rotational elements when said connecting members lie in said single plane and in said predetermined angular position;

a spring adapted to urge said rotational elements and said locking means apart on said common axis of rotation;

said spring means further adapted to permit rotational movement of said locking means and said rotational elements; and

, said spring means further adapted to maintain said rotational elements and said locking means in a substantially inseparable assembly;

three clips adapted for connecting preselected borders of said lampshade segments; and

,

means for mounting said lampshade on a lamp.

18. A kit for shipping a lampshade adapted for shipping in a knock-down state, said kit comprising:

(a) the lampshade of claim 12;

(b) packaging materials; and

,

(c) at least one instructional device for explaining the assembly of said lampshade.

19. A kit according to claim 18, wherein said instructional device is at least one device selected from the group consisting of printed materials, CD disks, magnetic data storage disks, and videotapes.

13. A method for knock-down shipping and subsequent reassembly of a lampshade adapted to be interconvertible between an assembled configuration having a first volume and a knock-down configuration having a second, smaller volume;

said lampshade comprising in combination;

at least two lampshade segments;

a predetermined number of connecting members;

a predetermined number of rotational elements;

said rotational elements adapted to be positioned within one another;

said rotational elements having a common axis of rotation;

assembly means adapted to permit rotational movement of at least said rotational elements and to maintain at least said rotational elements in a substantially inseparable assembly;

said connecting members adapted for connecting a preselected rotational element with a preselected lampshade segment;

slotting means on said rotational elements adapted to slottingly fit said connecting members;

said slotting means further adapted to position said connecting members to assume predetermined angular positions with respect to said common axis; and

,

locking means adapted for lockingly positioning said connecting members in said predetermined angular positions;

said method comprising the steps of;

(a) providing said lampshade in said assembled configuration having a first volume;

(b) unlocking said locking means;

(c) urging said rotational elements and said locking means apart on said common axis of rotation;

(d) positioning said segments into said knock-down configuration having a second, smaller volume;
