DETAILED DESCRIPTION

With references to FIGS. 1-4, a foldable decorative device 10 is shown. The device may be in the form of a decorative or ornamental device such as a Christmas tree as shown in the drawing figures. However, it is within the contemplation of the present disclosure that the device 10 is not limited to any particular shape or design.

The decorative device 10 may include an outer frame 12 having an inner perimeter 14 which defines an inner open space 16. The outer frame 12 may be formed of metal wire, plastic, wood, or other material, which can maintain a desired shape. The outer frame 12 may be supported on a base 18. The base 18 may have a configuration to support the decorative device 10 on a support surface such as a floor or tabletop. A pole or shaft 20 may extend generally orthogonally from the base 18 terminating at a distal top end 19. The outer frame 12 may be rotatably secured to the shaft 20. The shaft 20 extends along a vertical axis of rotation Y-Y. In an alternative embodiment, the outer frame 12 may be fixed to the base 18 such that it does not rotate relative thereto.

The decorative device 10 may further include one or more inner members 22, which are pivotally secured to the base 18. The inner members 22 may rotate relative to the frame 12. The inner members 22 may include an outer perimeter 24 having a configuration which fits inside the space 16 formed by the outer frame 12. In one embodiment, the outer perimeter 24 can have a shape substantially the same as the shape of the outer frame inner perimeter 14 as shown in FIGS. 2A-C. However, it is within the contemplation of the present disclosure that the shapes and configurations of the inner perimeter 14 and outer perimeter 24 may be different from each other.

The inner member 22 may be sized smaller than the outer frame 12 such that it can fit within the outer frame 12. The inner member 22 may be rotatable relative to the outer frame 12 such that it can assume a closed or storage position wherein the frame perimeter 14 aligns with and nests within the inner member perimeter 24 and space 16 as shown in FIG. 1. The inner member 22 may also be rotatable relative to the frame 12 toward an open or display position wherein the inner member 22 extends out of the space 16. A fully open position may be wherein a planar surface P1 defined by the inner member 22 is offset from a planar surface P2 defined by the frame 12 as shown in FIGS. 2A, 2C and 8.

In an alternative embodiment shown in FIG. 4, the decorative device 10 may include a plurality of inner members 22a and 22b, with each inner member being rotatably secured to the shaft 20. Each inner member may define a space 16. The outer perimeters 24a and 24b of the inner members are progressively smaller as the radial extent of the members are disposed closer to the shaft 20. For example, inner member 22b has a lesser radial extent than inner member 22a. This permits the inner members to freely nest within each other and also within the outer frame 12. Therefore, in a closed position the frame 12 and all the inner members 22a, 22b lie substantially flat in the same plane. The inner member 22b may be rotated independent of inner member 22a and frame 12. This permits each inner member 22a and 22b and the frame 12 to be positioned in their own orientation lying in three different planes, with each plane being offset from the other, when the decorative device is in the open or display position.

It is further contemplated that the innermost member may have a perimeter defining an open space or may be a substantially solid planar member including decorative images or elements thereon.

When the decorative device 10 is in the closed position, as shown in FIG. 1, the outer perimeter of the inner member may conform closely to the portion of the outer frame from which it is opposed. However, as shown in FIGS. 4, and 6-7, it is contemplated that the configurations of the perimeter of the inner member and the adjacent outer frame be different. It is desirable that the configuration of the outer perimeter of the inner member 24 be such that it can fit within the shape of the perimeter of the adjacent outer frame 12 to allow the device 10 to be fully closed substantially flat.

As set forth above, the shaft 20 extends from the base 18. In one embodiment, the base 18 may include two generally U-shaped members with an upper base member 50 disposed above the lower base member 52. In one embodiment, the upper base member 50 may be secured to the outer frame 12 and the lower base member 52 may be secured to the shaft 20. The lower base member 52 may be rotated relative to the upper base member 50 such that it may be moved from the folded position wherein it is generally parallel with the upper member (FIG. 1) to an open position where it is substantially orthogonal to the upper member (FIGS. 2B and 2C). In the open position, the stand provides a stable base for the decorative device 10. Alternatively, the base could be a non-folding structure removable from the shaft 20 for storage purposes.

In order to allow for the inner members 22 to rotate, each inner member 22a and 22b may have a pivot device 40 having an opening 42 (FIG. 10C) to receive the shaft 20. The pivot device 40 may be a tubular member with the opening sized to closely receive the shaft. The inner member 22 may be secured to a plurality of pivot devices 40 each having an opening extending therethrough to receive the shaft. As shown in FIG. 4, the innermost member 22b may be secured to one pivot device 40 and the other inner member 22a may be secured to two spaced pivot devices 40. The outer frame 12 may also be secured to two spaced pivot devices 40. The cooperation between the shaft 20 and the pivot devices 40 permits the inner member(s) to rotate relative to the shaft 20 and to each other as well as the outer frame 12.

As shown in FIG. 3, the pivot device 40 may be one long tube attached to the top and bottom of the inner member. In this embodiment, the outer frame 12 may be secured to two spaced pivot devices 40. The outer frame 12 may have a pivot device 40 at the top and bottom to receive the shaft 20 and allow for rotation. The hinge device 40 can be formed of a number of materials, for example, a polymer, such as PVC plastic, metal or wood. This listing is intended to be exemplary and not limiting.

It is contemplated that the inner member 22 may include a plurality of decorative elements each secured to a pivot device. With reference to FIG. 4, the inner member 22 may be formed of multiple design elements 22a-c and vertically spaced from each other. Each inner member 22 may be secured to a pivot device 40 disposed about the center shaft 20. The pivot devices 40 may join adjacent inner members. Therefore, all the members 22a-c are joined together and will rotate about the shaft together as shown in FIG. 9. Alternatively, each decorative inner member 22 may be separate from the other (see e.g. FIG. 4), therefore permitting the inner members 22 to be individually rotated. This can be used to create different shapes to achieve a particular desired aesthetic effect.

With reference to FIGS. 10A and 10B, in order to selectively restrict the rotation of the frame and inner members, the device 10 may include a locking apparatus 60. The locking apparatus 60 locks the inner member 22 in the open and closed position condition such that the decorative device 10 maintains the desired position. The locking apparatus 60 may include mechanically engaging elements formed on adjacent pivot devices 40a and 40b. One pivot device may include a protruding knob or tab 62 and the adjacent pivot device 40b may include a recessed notch or slot 64. The inner member secured to pivot device 40a with the tab 62 may be rotated such that the tab 62 sits within the slot 64, thereby locking the inner member into a particular position, such as the open or closed position. In order to remove the tab 62 from the slot 64, and thus permitting rotation, one may lift up on the inner member along the axis of rotation to remove the tab 62 from the slot 64 and then rotate the inner member to the desired position.

In an alternative embodiment shown in FIG. 11, the locking apparatus 60 may include a spring-loaded detent 70 having a spring 74 acting on a captured ball 76 formed in one of the pivot devices 40. The ball 76 is configured to engage a recess 72 formed in the shaft 20. Rotating the inner member relative to the shaft will overcome the spring force and permit the inner member to rotate. It is within the contemplation of the present disclosure that other known manners of selectively restricting rotation about a shaft could be employed.

The decorative device 10 may be formed of a plurality of segments to help facilitate assembly and disassembly of the decorative device 10. With reference to FIG. 12, the decorative device may be separable, for example, into three sections, a top 80, middle 82, and bottom 84. Each section may have one or more outer frames 12 forming a space 16 for receiving inner members 22, in a manner as described above. The inner section may be secured to a pivot device 96 that allows the inner members to rotate relative to the outer frames 12. This permits the inner member to be moved between an open or display position and a closed or storage position. Each section includes a central shaft 90, which is connectable to the shaft 90 of an adjacent section. The connection may be made by having the end of one shaft have a portion 92 that fits within a receptacle 94 the adjacent shaft. Alternatively, a collar or other joining element could be provided to permit the adjacent shaft to be removably connected. The connection may permit the adjacent section to rotated relative to each other. Alternatively, the connection may prevent rotation, e.g., by way of non-round connecting elements or one or more set screws. In this embodiment, the inner members 22 of each section may rotate independent of each other.

While the device 10 has been described as a decorative element such as a Christmas tree, it is also contemplated that the features of this invention could also be applied to non-decorative devices where space saving storage and ease of setup are desired.

While there have been described what is presently believed to be the preferred embodiments of the invention, those skilled in the art will realize that various changes and modifications may be made to the invention without departing from the invention, and it is intended to claim all such changes and modifications that fall within the scope of the invention.
