. CONSTRUCTIONAL TOY ELEMENTS CONSISTING 0F TUBES, PLATES, AND CONNECTING PIECES Filed May 25, 1934 Patented May 26, 1936 CONSTRUCTTIONAL TOY ELEMENTS CON- SISTING OF TUBES, PLATES, AND CON- NECTING PIECES Jerome Francis Kennedy, Berlin, Germany Application May 25, 1934, Serial No. 127,492

In Germany May 31, 1933 14 Claims.

The subject of the present invention is a constructional toy consisting primarily in metal parts, such as tubes or four cornered plates or strips with or without rounded comers and conmeeting pieces whereby of course wooden or other metal parts capable of interconnection with the above building elements can be employed. It also relates to elements thereof, as articles of manufacture.

According to the present invention the various building elements are joined together by means of connecting pieces, the partially flat or saddle shaped middle section of which is bendable and is provided with two or more flat or semi-cylindrical legs projecting, when the middle section is in the open of unbent position, from opposite sides thereof.

The connecting piece may be so constructed that the saddle shaped middle section thereof, when bent over the tube, forms a cylinder encompassing the tube in such a way that the projecting legs of the connecting piece are then projecting in the same direction and are capable of being inserted together into the hollow end of another tube or alternatively engaged with loops, slots, ribs or the like with which the other elements such as the plates are provided.

Objects of the invention consist in the provision of a novel connecting member, as an article of manufacture; a novel plate construction, as an article of manufacture; the combination of connecting members with tubular members, or with plate members, or with both, and, generally, in the provision of improved combinations of parts, and elements of construction, all as will more fully appear in the following specification, and be particularly pointed out in the appended claims. A feature of the invention, it will be noted consists in the provision of a connecting member capable of connecting, as desired, a tube with a tube, or a plate with a tube, or a plate with a plate. Another feature consists in the provision of plates with loops outstanding therefrom, arranged for binding connection with the connecting members, 45 or for direct connection with each other, as will be explained hereafter.

Preferably the legs of the connecting piece are tapered or formed in a semi-conical-shape so that they, on the one hand can be inserted easily into 50 slots or loops on the plate element or into the hollow end of the tube, and so that onthe other 'hand the pressure brought to bear on the connecting piece upon the tube can be increased by pushing the half conical legs into the tube; the

55 further the legs are pushed in the greater beincreased by constructing the legs of the connectcomes the pressure both upon theinterior of the tube or of the loops of the plate into which the legs are pushed and upon the exterior of the tube around which the saddle shape section is placed, the split in the cylinder when the ends of the sad- 5 dle section meet allowing suflicient play for this purpose.

It is clear that the increase of pressure on the one element e. g. a tube, produces an increase of pressure upon the other element e. g. in the loops of a plate or interior of a second tube and conversely.

The pressure between the connecting piece and the two elements to be connected can be further ing piece in such a way that they do not lie directly in line with one another, in other words, so constructed that one leg is slightly oflf set from the other, so that on insertion into the interior oi? the tube or loops additional pressure is brought to bear both on the interiorof the tube or loops and by reason of the twisting or scissor action so effected, also upon the tube around which the saddle section is placed: The pressure resulting from the twisting or scissor-action causes the corners or edges of the saddled section to have a tendency to dig into the surface of the tube thereby preventing not only the twist but also longitudinal slip upon the tube.

The connecting piece when in the flat i. e. before the saddle section is bent round can be used if placed one upon the other as a. connecting piece to join two tubes together in prolongation or can be used singly tojoin one plate to another, or one tube to another and can be bent to any desired angle.

Further the legs may be provided with notches in such a way that on insertion of the legs into the loops or slots on the plates or into the interior of the tube, the notch or notches may efi'ect a snap grip therein.

It is also possible to provide the saddle shaped section with holes so that a tube may be passed through the hole enabling it to be connected with another tube, the legs of the connecting piece being passed into the end of the second tube.

According to this invention the plates appertaining thereto are so constructed as to provide a means of engagement with the said legs of the connecting piece by providing the said plates with raised loops or slots which correspond in size or shape to the said 'legs of the connecting piece.

This can be attained for example in the case of the clamping oi the legs while preventing'rotation oi! the said semi-cylindrical legs within the cylindrical opening provided by the loops. which latter prevent lateral movement of the connecting piece. I i

The connecting piece can also be so constructed .that the projecting legs are provided with ribs or notches capable of engagement with corresponding ribs or slots in the plate- 1 t It is also possible, besides being ableto connect plates with each other by means 0! the connecting pieces, to connect them together directly with.

- one another. For this purpose, the loops on the plate are so formed that whenthey are placed over one another the loops 0! one plate can be snapped into the loops or slots in another plate somewhat in the manner of. a so called press button.

A special feature of the plate is its flexibility in both directions whereby step like formation of the plate is possible. The plates are bendable at those pointsat which no loops or ribs are raised out of the normal plane. If the raised loops are placed at regular intervals on the plate therelore it is possible to bend'the plate to any desired angle at points lying between the loops in such a way as to-make for example, regular steps or a substantially circular wheel.

The plates can be iurther provided with holes through which the tubes may be passed.

' A technical advantage of a constructional toy which is provided with connecting pieces accord- Y ing to the present invention, is its property of enabling interconnection o! the various building elements with one and the same connecting piece, whereby for example, one single type oi connecting piece is capable or connecting a tube with a tube, a plate with a plate and also a tube with a plate, thus reducing the number or connecting pieces required for building a larger variety of models than would otherwise be possible.

The accompanying drawing shows asan example parts constructed in accordance with this invention.

Figure .1 shows in cross section and in plan and in elevation a T shaped connecting piece with saddle shaped middle section after having been bent in cylindrical form and showing the projecting legs.

Figure 2 shows inside elevation, a similar connecting piece with a short saddle shaped section.

Figures 8 and 4 show inside elevation two further types of connecting pieces with angularly disposed legs.

Figure 5 shows in cross section and in plan a connecting piece in double T shape. Figure 6 shows in side elevation a connectin piece for the parallel connection or two tubes or one tube and a plate.

Figure 7 shows in side elevation a connecting piece for angular connection with a short saddle. Figure 8 shows in plan, in sectional elevation, and in cross section a means 0! connecting tubes with plates.

Figure flshows the connection of two plates with one another,

I Figure 1c shows in sectional elevation two wheel hubs and in end view, this same connecting piece constructed in accordance with this invention.

forms described trom a saddle shapedsection I and projections or legs 2, 3. It may conveniently be formed from a thin metal stamping, in which, it will be noted, the saddle shaped section i comprises a bendable central band or strip which, before bending, may be somewhat arched in the lengthwise direction of the piece, or'may be substantialiy' flat, with its end jedges arched downwardly somewhat, the arms or legs, 2, 3, extending outwardly from these end edges, either parallel to each other and to the central strip (before bending), or at angles to'the central strip and to each other. In the first case, of

course, tubes may be connected together at right angles to each other, by such connecting pieces, and in the second case, at other angles to each other. The arms, or legs, 2, I, it will be seen, are

preferably arched'laterally, and are preterabiy made of tapering shape, longitudinally, with rounded'ends, all of which may readily be provided in stamping the piece out. As will be seen. from the drawing the two legs are set at a slight angle to one another, when the central section I has been bent around a tube, in such a way that on connecting them to a plate or tube inthe manner described a lever action is effected and when a tube is situated within the saddle section after being bent into cylindrical form, this lever action (which is caused by bringing the legs in line with one another on inserting them into the loops or tube) causes the points 4 and 5 oi the saddle section I to press against the tube 6. The saddle section I and the legs 2 and l are so constructed that a plate I can be inserted between the'said legs and a clamping action takes place between the loops I on the plate I and the legs {and 8 on their insertion into the said loops.

In Figures 3, 4, and"! examples are shown of the connecting piece set at an acute and obtuse angle to the saddle section.

In Figure 5, is shown a connecting piece which enables two parts to be connected together lengthwise or three tubes crosswise, in which the connecting piece is constructed out of two parts I2 and it, which when the saddle sections thereof are placed together to form a cylinder the two with connecting pieces through the medium of loops 8. It will be noted that the length of the central strip i of a connecting member is such, in relation to the circumference of a tube about which it is to be bent. that when it encircles the tube the space between the two ends of the central strip, and therefore the space between the bases of the two arms or legs of a coacting pair, 2, I, is substantially equal to the thickness of the plate I, so that when the arms 2, 3, are forced well down through loops 8, 8, on opposite sides of the plate, they may lie quite closely against the faces of the plate, and the central strip l of the connecting member will be drawn tightly about the tube which it encircles. Figure 9 shows a connecting piece I! with two parallel pairs of legs l8 and I9 connecting two plates together.

The connecting piece l1 when in the openeron the other side, so that the loops on the under side of one plate may be snapped over loops on the upper side of another plate, it being noted that the plates are preferably made as stampings of light metal, with the loops struck up on opposite sides, these loops therefore being somewhat resilient.

In Fig" re 10 is shown the connection of a tube with a eel hub 20. The two legs 23 and 24 are ofiset i. e. not parallel to one another so as to eifect a tight joint.

Figure 11 shows an alternative method of connecting a tube to a plate whereby the connecting piece has three legs so shaped that they engage with a rib on the plate. The legs of course may alternatively pass through slots in ribs on the plate.

The legs 2 may be provided with notches 3| in which the loop or loops 8 engage, it is an advantage to provide two or three notches one behind the other. It is thus possible, by altering the position of the loops and notches to increase or decrease the pressure or grip of the one part with the other. If the notch is on the edge of the leg, the scissor action of the legs will cause it to engage in the loops.

The tubes 6 may also be provided with notches or ribs to engage in the notches 31 of the legs when the latter are inserted in the tube.
