# 6 A f oze/IE United States Patent ARTICULATED NESTABLE DEVICE Erling G. Henrickson, Los Angeles, Calif.

Application July 5, 1955, Serial No. 519,$25 .6 Claim 1 6 This invention is directed principally to an articulated structure having a plurality of components nestable one within another, the device being useful for many and varied applications as described in detail hereinafter.

A principal use of the device made in accordance with the present invention is in connection with a plaything of the pull-toy variety, that is, a toy made up of a number I of substantially rigid components flexibly interconnected so that the components may be disposed in tandem and thus pulled by a baby or young child through a towing string or the like attached to the front end. The exterior surfaces of the component members of the toy and to some extent the configuration and size of the components may be so decorated and formed as to simulate an elongated animal such as a snake, alligator or the like or the device may be so shaped, as is shown in the preferred form of the invention herein disclosed, as to simulate a railroad engine having a plurality of cars attached thereto.

The invention also contemplates use in other fields such as in jewelry where an elongated device made up of a number of flexibly interconnected relatively rigid elements is useful as a necklace or bracelet.

It is characteristic of the present invention that the individual substantially rigid components thereof are of progressively increasing size from the" smallest component at or near one end of the device to the largest component at another point which may be the other end of the device, the members being nestable. Thus in the simplest form of the invention a plurality of generally cubical, hollow members having open tops and fronts are provided, the largest of such members serving as not only the last element in the completed device when in extended form but also as a carrying and protective case for the complete structure. The largest of the component elements may itself be made up of two generally cubical receptacle portions arranged in back-to-back relation, with flexibly interconnected relatively rigid components adapted to extend in either direction from the center of the completed structure. In this latter form of the invention all component elements extending in one direction from the largest element are nestable within a portion of the largest element, while all component elements extending in the opposite direction from the largest are nestable in the other portion of that largest element.

An object of the invention is, therefore, to provide a novel device made up of a plurality of flexibly connected nestable component members.

Another object of the invention is to provide a pull toy or the like adapted to be several times longer than its width when extended in operative position and capable of being assembled into compact form for storage.

A further object of the invention is to provide a device having the above characteristics and advantages which can be made and sold very economic-ally.

These and other and allied objects of the invention will become clear from a study of the following description of a preferred embodiment thereof taken in connection with the accompanying drawing in which:

l is a central vertical sectional view of a preferred form of the present invention, the component members thereof being nested one within another so that the entire structure is in compact form.

Fig. 2 is a perspective view of the device of Fig. 1 in partially extended or operative relation, the smallest two members being shown in dotted outline in completely extended or operative position, and wall portions of another member being partially broken away for clarity of illustration.

Fig. 3 is a perspective view of a modified form of the invention constituting in eflect a pair of devices generally similar to that of Figs. 1 and 2 with their largest component members arranged in back-to-back relation.

Referring now in detail to the drawing, there is shown in Figs. 1 and 2 a device having four nestable members. The outermost, largest component member is indicated at A and constitutes a generally cubical hollow container having a bottom 10, side walls 12 and 14 and a rear wall 16 The member A has an open top and an open front in order to permit nesting of the remaining components therein as will be later understood.

A second member indicated at B is of substantially similar shape to that of the member A except that the height, width and depth of the member B are somewhat smaller than the corresponding dimensions of member A in order to permit member B to be received and nested within A when B is rotated about a transverse axis. Thus the member B includes a flat bottom 23, upstanding side walls 22 and 24 and a rear wall 26, the member B having an open top and an open front similarly to the member A. In the particular example here illustratively shown, additional generally box-like members C and D are provided, each being generally cubical in shape with flat bottoms 30 and 40 respectively, side walls 32, 42, 34, 44 and rear walls 36 and 46. Again, each of the members C and D has an open top and an open front and their heights, widths and depths are respectively smaller than the corresponding dimensions of the elements B and C respectively in order to permit nesting as referred to above. Desirably the height, width and depth of each member are virtually equal. If they are not, then the height of one member must be smaller than the depth of the next larger member to permit nesting; in any event the width of each member must be smaller than the width of the next larger.

Means are provided for flexibly connecting each of the component members A, B, C and D with the next member in sequence. In the present illustration such attachment means include a flexible element 17 (see Fig. 1) connecting members A and B; flexible element 27 connecting members B and C; and flexible element 37 connecting members C and D. As is clearly shown in Fig. 2, spec itically with reference to flexible element 27, such connecting element extends between the front portion of the bottom of member B and the rear portion of the bottom of member C and is desirably centrally disposed laterally of those members. The ends of the attachment elements 11,21 and 37 may be rigidly fixed to the respective bottoms by suitable means such as rivets 18 and 19. The connecting element itself may be made of any suitable flexible material such as cloth tape or equivalent.

When the present invention is adapted for use as a pull toy fora child, it is desirable that the innermost or smallest of thecornponent articulated members be made to simulate a railroad locomotive or similar vehicular prime mover. Such a component member is indicated generally at E and may include a rear portion 52 and a body portion 54 provided with the usual appurtenances such as a simu- 3 lated smo'ke stack 56 to enhance the resemblance of the device to a locomotive. Desirably, a pull string 58 may be included for use by the child, such string being here shownas attached to a simulated .cow catcher 6010i the locoi notive. The component member E .isfflexibly; at-

tachedto the front portion .of the -bo ttomi40 of the next larger element D by a flexible connecting lelement lfl of each of; the successive component members A, B, C

and D. In Fig.2 such a wheel is indicated generally at 70 being received in an opening 72 formed in the bottom 30 of the member .C. The wheel or roller 70 is rotatably mountedon pin or axle means 74, the ends of 'the axle being fixed to the bottom of the supported component member C by suitable means such as a flat sheet 76 underlying and fixed to the bottom 30.

similar to the elements .17, 27 and 37 previouslyieferred It will be now understood that the structure as seen in section in Fig. 1 may be unrolled into elongated operative relation as seen in Fig. 2, such unrolling being readily accomplished since the component members are of-sizes to fit easily within one another. Similarly, the device may be refolded into its compact or nesting relation after use and thus occupies a minimum amount of space in storage.

In Fig. 3 is shown in partially unrolled condition a device embodying the present invention and including a central rigid member indicated generally at80 and made up of two receptacle portions, each being approximately cubical in shape and defined by a bottom, side walls 82 and 84 and a common transverse Wall member 8 6' which serves as a back for each of the two receptacle portions of the member 80. Additional generally cubically shaped open topped and open fronted elements are. provided and are indicated generally at 90 and 92 extending in one direction from the central member 80 and at 9fland'96 ex 1 tending in the opposite. direction from the'central member 80. Each of the series of component members '90 and 92 are connected together by flexible attachment ele- 'ments, one of which appears at 98, in order to permit extension of the device in the manner discussedhereinabove as well as nesting of the componentelements as will be understood. a

It willbe seen that the present invention, in any of its forms, may be made of any suitable material such as thin sheets of wood, plywood, thin metal members, or plastic or other substitute materials. It will be understood that although the elements have been referred to herein as rigid, a slight degree of flexibility of the component elements is not objectionable and is contemplated herein.

Modifications and changes from the particular forms hereinabove shown as illustrative in thepresent invention may be made and are within my contemplation. such modifications and changes not departing from the spirit of the inventionare intended to be embraced within the scope of the appended claims.
