Lima, Sierra Madre, Calif. 91024 Filed Feb. 25, 1965, Ser. No. 435,225 18 Claims. (CI. 46-17) This invention relates to toys and more particularly to a unique construction toy having a variety of simple structural components, fastener assemblies and accessories adapted to be assembled in a great variety of arrangements challenging to the manual dexterity and imagination of young people.

The invention toy construction kit comprises a plurality of structural components of varying length some of which are square and others rectangular in cross section, and each provided with rows of uniformly spaced openings. The square-section structural members have intersecting pairs of holes identical with one another and including a deep well and a shallow bottom provided with a small diameter axial bore adapted to receive a threaded shank of a fastener component, a shaft or an axial unit. Desirably, a pair of the Well openings intersect one another. Other of the structural components are relatively thin and serve as connecting struts and braces and their openings correspond in size and spacing with the axial openings through bottoms of the aforementioned wells. Still other of the thin members comprise plates or plaques of assorted sizes each preferably provided with crisscrossing rows of small openings spaced apart similarly to the openings in the other structural openings and adapted to receive the shanks of the fastener members, and the like.

The fastener assemblies include a cylindrical or spoollike member fitting loosely in and exactly filling the wells. Each is provided With a threaded axial bore at either end and a pair of diametric threaded bores at right angles to one another. The latter are positioned to lie intersect along the longitudinal center of the square structural members when the cylinder is seated in any well. Thus a threaded bore is always accessible to a threaded shank member inserted through any opening from any face of the square members. The threaded shanks comprising the other main component of the fastener assemblies are of varying lengths and some are headless while others are provided with a head. The headless shanks are useful in connecting two cylindrical members together while seated in the wells of adjacent structural members. Other accessory components of the kit include disks, pulleys and wheels, shafts, spacers, thumb nuts, belting etc.

A feature of the invention is the fact that the fastener assemblies are, in general, located internally of the structural parts in their assembled positions. The relatively large cylindrical member may be viewed as a nut having a series of threaded openings any one of which is adapted to receive and mate with the end of a threaded shank. In certain assemblies of the parts, the end of this cylindrical nut is clamped against the bottom of the well in which it is located while in other arrangements the cylindrical member is held clamped against the Well side.

Accordingly it is a primary object of the present invention to provide a unique and improved construction toy kit, components of which are adapted to be held in a great variety of assembly arrangements by simple threaded fastener assemblies of a unique character.

Another object of the invention is the provision of a toy construction kit having a plurality of similar structural elements of varying lengths and shapes each provided with rows of openings adapted to seat and support fastener assemblies which are substantially concealed when used to hold components together.

Another object of the invention is the provision of a construction kit having a plurality of elongated rigit members provided with rows of uniformly-spaced hole each including a deep cylindrical well having a relativelj small diameter hole through its bottom.

Another object of the invention is the provision of toy construction kit having structural components pro vided with a series of holes and adapted to be assembler face-to-face, end-to-end, or with the end of one helc clamped against a face of the other.

Another object of the invention is the provision of a top construction kit utilizing fastener assemblies, including both headed and headless threaded shanks, and a nut some of which comprise cylinders having both threaded axial and diametric bores intersecting with one another at right angles along the longitudinal axis of the cylinder.

These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawings to which they relate.

Referring now to the drawings in which preferred embodiment of the invention is illustrated:

FIGURE 1 is a plan view of the invention construction kit showing the typical components and accessories disassembled;

FIGURES 2 and 3 are cross-sectional views on an enlarged scale taken respectively on lines 2-2, 33 of FIGURE 1;

FIGURE 4 is a cal fastener nuts;

FIGURE 5 is a perspective view of a toy wagon assembled from kit components;

FIGURE 6 is a cross-sectional view on an enlarged scale showing a detail of the front axle assembly; and

FIGURE 7 is a cross-sectional view through one of a great variety of joints which can be assembled utilizing the versatile fastener assemblies.

Referring initially more particularly to FIGURE 1, there is shown typical components of the construction kit arranged in the bottom half of a shipping container 10 and made of any suitable rigid material as wood, molded rigid thermoplastic, or the like. Arranged parallel to one another in the upper left hand corner of this container are a plurality of structural members of square configuration and varying lengths. In the lower left hand corner and along the side are other structural components of varying lengths generally similar to the square components but rectangular in cross-section and suitable for use as struts and braces. Thin plaques or plates 13 are also provided in varying size-s and each having rows of holes spaced apart similarly to the spacing between the holes in the other structural components. Centrally of FIGURE 1 are both small disks 14 and larger disks 15 each desirably having a recessed or grooved periphery useable to support a belt, to guide the disks along a rail or track, or other purposes. All disks have a central opening to receive a shaft, axle or fastener, and disks 15 are also provided with additional holes spaced apart similarly to the holes in the other structural members.

The kit also includes the unique and important fastener assemblies including a plurality of threaded cylindrical nut members 17 and an assortment of threaded shanks of varying lengths, some being headless and others having heads. Also provided are thumb nuts 20 for use on the threaded shanks 21 and the threaded portions of rods 22 and cranks 23. In addition, the kit preferably includes an assortment of auxiliarly members, such as the journal boxes 24, rectangular member 25, washers 26 and spacers 27, a crane hook 28, belting or line 29 and a suitable tool 30 for use with the threaded fasteners.

Referring now more particularly to FIGURES 3 and 5, it will be understood that each structural member 11 of perspective view of one of the cylindriquare cross-section is preferably provided with rows of penings extending centrally along each face and having he configuration best shown in FIGURE 3. As there hown, these openings include relatively large diameter 76115 32 opening through two adjacent faces 33, 34. These wells are arranged in pairs with their axes intersecting .nd lying at right angles to one another and to the longiudinal axis of the structural member itself. To be noted [1 particular is the fact that the depth of wells 32 is subtantially greater than one-half the face width of member .1 but substantially less than the face width. The result is hat each well has a rather thick bottom 35 provided with tn axial bore 36 loosely receiving the threaded shank of a astener 18. A similar bore 37 is located axially of each :nd of members 11 for a purpose to be described presently.

Referring now to FIGURE 4 it is pointed out that the :ylindrical fastener nuts 17 are made in one piece from tuitable material such as metal and have a size exactly fillng the identical wells 32 in the structural members. Thus he length of member 17 corresponds to the depth of wells 52 and their diameter corresponds to but is one or two mils imaller than the well diameter so as to slide easily into and out of assembled position therein. Each of nut mem- Jers 17 is provided in its opposite ends with a threaded axial bore 40, 41. In addition there are a pair of threaded diametric bores 42, 43 which intersect one another along the longitudinal center line of the structural member and at right angles to one another when properly seated in wells 32. These important details are made clear by FIG- URES 6 and 7.

Referring to FIGURES 6 and 7, it will be apparent that the described cylindrical nuts and threaded shanks 18 may be assembled to one another and between construction members in a great variety of arrangements. Only a few illustrative assemblies are shown in these two figures, other typical ones being shown in FIGURE 5. These representative modes of assembly are believed self-explanatory. It will be observed that some of the components are held assembled by a headed shank 18 whereas others are held together by a headless shank. See for example, the two lower structural elements 11 in FIGURE 7. These shanks can be assembled between aligned axial bores of nut member 17 or one end of the shank may be threaded into a diametric bore of one nut and the opposite end into the axial bore of a second nut member. In all cases, both cylindrical nuts 17 and either the headless or headed shank extending between the two nuts are concealed or lie within the confines of the structural members. Occasionally the head of a headed shank will be exposed, as for example, when used to secure one of the brace members 12 to another structural component, an example of which appears in the forward carriage unit in FIGURE 5. It will be understood that all of the threaded members desirably have a reasonably snug fit with one another so that the parts do not become unthreaded where it is desirable to avoid fully tightening the fastener parts. This has the advantage that when it is desirable to have relative rotary movement of one structural part relative to another the threaded shanks can be left sufficiently loose to permit this rotary movement without risk of the fasteners becom ing disassembled during the use of the toy.

Normally a wrench or tool is not required in the disassembly or assembly of the parts but instead proper manipulation of the structural parts being assembled can be utilized to tighten and untighten the fasteners. However, in certain cases a wrench is useful such as the screwdriver 30, the bit of which can be inserted in the kerf 44 transversely of one end of members 17 (FIGURE 1). A thin coin may also be used as a wrench.

The presence of the axial bores 37 at the end of the square structural members ll permits either of their ends to be clamped either against the face of a structural member or in axial alignment with another. When the latter mode of assembly is employed, it will be evident that square members of any desired length can be assembled in end-to-end relation by selecting appropriate length subcomponents.

Journal boxes 24 are made in the configuration best shown in FIGURE 6 and include a transverse opening 45 seating a bearing sleeve 46. A shaft, crank, or axle may be assembled through these bearings.

Disks 14, 15 are preferably provided with broad rims having a centrally located shallow groove 48 seating a belt or mating with the top edge of a rail or trackway.

While the particular construction toy herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the details of construction or design herein shown other than as defined in the appended claims.
