Detailed Description of the Invention and the Preferred Embodiments

As shown in the attached figures, in accordance with the invention, a construction 10 is

provided having a plurality of telescoping arms 20. Construction 10 is preferably provided for

use as a toy, whether by children or adults; or it can be used as a geometric sculpture.

Alternatively, construction 10 could be used for any other suitable application. As discussed

below, construction 10 can be manipulated for entertainment or artistic purposes to achieve any desired shape available consistent with the structure oi τne ueviue.

In the preferred embodiment, each arm 20 includes a plurality of segments or sleeves 22a,

22b, 22c, 22d, 22e, and so forth, as shown, for example, in Figures Ia and Ib. Arms 20, and any

other component of the construction 10, can be made from any desired material, whether plastics,

metals, alloys or composites, or so forth, and can be any size, shape or color desired, consistent

with the functional requirements of the device set forth herein. Thus, while five segments 22a

through 22e are shown, it will be understood that the features of the figures are merely provided

for illustrative purposes and are not intended to serve as a limitation on the scope of the invention

as described or claimed herein. More or less segments can, of course, be provided as desired.

As shown in Figures Ia and Ib, in a preferred embodiment, each segment or sleeve 22

is nested within the preceding one. Thus, segment 22e is nested within segment 22d, which is

nested within segment 22c, and so forth. Preferably, the lower segments of arm 20 are of greater

diameter, with the diameter of each consecutive upper segment being of successively decreased

diameter, such that the diameter of segment 22a is greater than of segment 22b, which is greater

than that of segment 22c, and so forth. Alternatively, the configuration can be reversed, such that

arm 20 has the lowest diameter segment positioned on the bottom, with each consecutive upper

segment being of successively greater diameter than the one below it.

As a result of the nested configuration of the segments in arm 20, a telescoping arm

structure is provided, as shown for example in Figures Ia and Ib. Some or all of the segments

22a through 22e can be fully or partially retracted into its adjacent segment; or, conversely,

segments 22a through 22e can each be partially or fully pulled out of the adjacent segment it is

nested in. As a result, the overall length for the telescoping arm 20 can be shortened or

lengthened as desired, hi other words, by pulling segments apart or pushing them together, the

total length of telescoping arm 20 can be increased or decreased as desired. Preferably, all of the segments are nested together, although, alternatively, construction 10 can be formed such that

only some segments are nested and not others.

Preferably, each arm 20 includes an end cap 40 at its tip (i.e. on its distal end). Although

a small spherical end cap 40 is shown for illustration purposes, end cap 40 can be any size, shape

or color desired. It can also be constructed of any desired material. For example, end cap 40 can

be magnetic, to allow attachment of other magnets or metallic items to the toy, attachment of

desired articles to the end cap, attachment of the toy to a metallic surface, attachment of two toys

together, or so forth.

Alternatively or additionally, end cap 40 can include hooks, or hook and pile tape (also

known under the trademark Velcro®), likewise to attach items to the toy, or to attach the toy to

desired items or surfaces, or to attach two toys to each other.

Alternatively or additionally, each end cap 40 can include a ring with a movable sliding

segment which is used to expose or close a gap in the ring (as is commonly used, for example,

as clasps for necklaces). In this manner, the ring of end cap 40 can be opened and closed to secure it to another end cap of the toy 10, or to an end cap of one or more other toys to secure the

toys together in a linked configuration. Or, the ring of the end cap can be opened and closed to

secure it to any other suitably sized ring.

In further alternative embodiments, different types of end caps 40 can be provided at the

ends (i.e. tips) of different arms. For example, male and female types of end caps can be

provided, allowing interlocking or linking of end caps in the same toy or between toys. While

the end caps are preferably fixed in place, alternatively, they can be removable. For example,

removable tips can be used to provide a different appearance at the end of the arm, or to change

the type of end caps on the tip of a given arm.

Further in accordance with the invention, one or more of the telescoping arms 20 are provided with one or more joints therein. Preferably, the majority of the arms or all ot trie arms

are provided with joints.

Preferably, two or more joints are provided on one or more arms. Any type of joint can

be used. By choice of the type of joint (ball and socket, pivot or so forth), portions of arm 20 can

be rotated in a desired fashion relative to other portions of that same arm, and relative to the

overall construction 10 itself. Thus, one or more portions of arm 20 can be rotated either in a

two-dimensional plane or can be rotated in three dimensions depending on the type of joint

utilized. Any combination of number of joints on an arm and/or types of joints and/or number

of arms containing joints can be used consistent with the invention.

In one embodiment, telescoping arm 20 includes a first joint 50 below the lowest

segment 22a. In one preferred version of this embodiment, joint 50 pivots, allowing two-

dimensional rotation about the joint, as shown in Figure 2. For example, joint 50 can consist of

a segment 46 having a hole therein, through which is secured an axis 44 such as a bar or screw.

In this preferred embodiment, joint 50 allows bending of arm 20 (i.e. flexing or rotation within

a hypothetical plane 52 represented by the plane of the paper in Figures 2a-2c). Thus, arm 20 can

rotate approximately 180 or more degrees around axis 44. In the embodiment shown, arm 20 can

rotate about approximately a 270 degree arc, although an arc of fewer or greater degrees can be

provided depending upon configuration of the joint and the structure below it.

In an alternate or additional embodiment, telescoping arm 20 includes a second joint 60

below joint 50, as shown in Figure 3. In a preferred embodiment, joint 60 is formed by the

nesting of cylindrical segment 46 within a cylindrical segment or sleeve 56. Joint 60 allows for

rotation of segment 46 of arm 20 into and out of hypothetical plane 52. Preferably, the arm

rotates in a full circle (360 degrees) at this joint. Joint 60, therefore, allows two-dimensional

rotation in a plane perpendicular to that of plane 52. As a result, the combination of joint 50 and joint 60 allows three-dimensional rotation or portions oi arm zυ.

For example, Figure 3a shows arm 20 in a first position wherein the arm is within plane

50, with arm 20 being bent downward at an angle of approximately 75 degrees. Figure 3b

subsequently illustrates the construction of Figure 3a after arm 20 has been rotated via joint 60,

such that arm 20 is no longer within plane 52. Rather, arm 20 now extends up out of the plane

with the end cap 40 pointing toward the viewer. Figure 3 c subsequently illustrates the further

bending of arm 20 downward at joint 50, such that the arm is now bent at an angle of 90 degrees

at joint 50. hi Figure 3c, arm 20 now extends perpendicularly out of the plane of the drawing

sheet, and toward the viewer.

As noted, arm 20 rotates three hundred and sixty (360) degrees at joint 60. Therefore, if

desired, arm 20 could be rotated from the position of Figure 3c back into the plane of the page.

This rotation could then be continued until arm 20 is 180 degrees opposed from the position in

Figure 3 c, such that it extends down out of the plane, perpendicular to the page, and away from

the viewer. It could likewise be continued to form a complete circle.

Thus, in one preferred embodiment, each of the arms 20 is constructed similar to a VHF

antenna for use with a television set, or the antenna of a radio, or similar in some ways to the

telescoping arm of a doll. However, in accordance with the preferred embodiment of the

invention, the arm 20 is not in communication with wire for attachment to a television or radio,

unlike an electronic antenna. Rather, a plurality of telescoping arms 20 are joined together for

entertainment, the term entertainment being intended to include toys for play purposes and

sculptures for artistic or aesthetic purposes. Likewise, unlike telescoping arms of other toy dolls,

arms 20 are preferably joined together without the use of an intermediate torso. As shown, for

example in Figure 4a, a right arm 20 can be directly affixed to a left arm 20 with no torso in

between. Larger numbers of arms can also be connected to each other, as discussed below. In the preferred embodiment of the invention, three or more arms 20 are joined together

to form the construction 10. Preferably, by use of three or more arms a construction is provided

which is self-standing, hi other words, construction 10 can be balanced solely on end caps 40

of arms 20, with the end caps 40 being positioned against a desired surface. Thus, the

construction can independently stand on a table or other surface (whether flat or otherwise),

without being mounted to a base or using other supports.

For example, in one embodiment, as shown in Figure 4b, three (or more) arms 20 can be

joined at a central point 70 to form toy 10. Alternatively or additionally, the arms can be

connected sequentially, hi one such embodiment, the arms can be stacked as illustrated in Figure

5c. For example, pairs or triplets or groups of four or more arms can share or be joined at a

central point, with several central points being riveted or attached together.

As shown in Figure 4b, each arm can be provided at any desired angle to the other two.

hi the preferred version of the three arm embodiment, the angles are all equal, with each arm

forming a one hundred twenty (120) degree angle to the others. Through use of a three or more

arm configuration, a stable self-standing construction is provided, hi such a self-standing

embodiment, construction 10 can stand on its own without need for a base, torso, or other

support, by resting the end caps 40 against a surface.

It may be noted that in this embodiment, and in the other embodiments below utilizing

a plurality of arms, the arms are labeled sequentially 20-1, 20-2, etc., to distinguish each arm

from prior or successive arms. It may also be noted that in each of these embodiments, while the

structure of each arm is preferably identical to the arm before and after it, this need not be the

case. Thus, the arms may be of different maximum lengths, may have different numbers of

segments, different numbers or types of joints, or so forth, hi one preferred embodiment, each

arm includes a first joint 50 and a second joint 60, as described herein, although this is not mandatory to De consistent wiin me mveiiuυπ.

In a further preferred embodiment, four arms 20 are j oined at a central point 70, as shown,

for example, in Figure 5a. Central point 70 can be a fixed point, such as a rivet, or can be a

further joint of any type, if desired. hi Figure 5a, each arm 20 can be provided at any desired angle to its two adjacent arms.

In the preferred version of the four arm embodiment, the angles between the arms are all equal,

with each arm forming a ninety (90) degree angle to the arms adjacent to it. Any further number

of arms (whether five, six or more) can likewise be used consistent with the invention.

In a further preferred embodiment of the invention, an array of telescoping arms 20 is

stacked three dimensionally in a series of layers, as shown for example in Figures 5b and 5c.

Figure 5b, for example, illustrates a variation on the embodiment of Figure 5a wherein two layers

of arms are utilized, for a total of eight arms, with a second arm being located beneath each of

the four arms of the top layer. In Figure 5b, the bottom arms are each bent at approximately a

45 degree angle for illustration purposes, to visibly distinguish them from the top arms. Thus, arm 20-5 is located beneath arm 20-1 , arm 20-6 is located beneath arm 20-2, arm 20-7 is located

beneath arm 20-3, and arm 20-8 is located beneath arm 20-4.

Further layers can be provided as well. Figure 5c, for example, illustrates a side view of

an twelve arm, multiple layer structure. In the figure, an upper three arms and lower three arms

are visible in the plane of the page; a middle three arms are shown extending out of the plane of

the page toward the viewer; and the bases of the remaining three arms are shown as well, those

last three arms being arms that extend out of the plane of the page and away from the viewer.

The structure of Figure 5 c is similar to that shown in Figure 5b, in that a four arm configuration

is provided for each layer, except that each arm is straight in Figure 5c. (Ln other words, in

Figure 5c, the lower levels of the arms are not bent, unlike the illustration in Figure 5b). By varying the size and thickness ot individual componenxs, τne layers can υc spα^cu uum tαui

other as desired. In a preferred embodiment, the layers are nestled together relatively compactly,

as shown, for example, in Figure 5d. Any number of layers can be used, with any number of total

arms and number of arms per layer, and any desired variation or combination of number of joints

per arm, types of joints per arm, and so forth.

Accordingly, using the principles of the invention, a construction 10 is provided which

can be manipulated into a wide variety of entertaining and artistic shapes. The construction can

be initially of any size, color, appearance, or configuration desired, consistent with the

construction techniques described herein.

Several examples of some of the unusual shapes which can be created using the invention

are shown, for example, in Figures 6a and 6b. As shown therein, the construction can be

manipulated into any shape desired by the imagination, limited only by the configuration of arms

and joints provided. Using the telescoping arms and joints provided in the structure, a child or

adult can repeatedly extend, retract, bend and/or rotate the arms of the invention, resulting in

entertainment for a prolonged period. The construction can be used as a toy or as a geometric

sculpture, for a child or adult to play with, or to hang (as a mobile, for example, or on a wall).

Preferably, it is designed to stand on its own (e.g. using three or more arms), although,

alternatively it can be mounted or connected to a base.

Having described this invention with regard to specific embodiments, it is to be

understood that the description is not meant as a limitation since further embodiments,

modifications and variations may be apparent or may suggest themselves to those skilled in the

art, or may fall within the scope of the appended claims, whether literally or via equivalents. It

is intended that the present application cover all such embodiments, modifications and variations.
