LEONARD W SCHQPEI? United States Patent 3,221,439 CGNNECTGR FOR TOY ROD CONSTRUCTION ELEMENTS Leonard W. Schaper, West Orange, N.J., assignor to Orange Products, Inc., Orange, N.J., a corporation of New Jersey Filed Apr. 27, 1962, Ser. No. 190,668 3 Claims. (Cl. 46-29) My present invention relates to improvements in elements for toy building construction sets.
In such sets small rods, known in the trade as logs, having regularly spaced, circumferential, grooves are assembled and held in assembled relation by means of connectors of resilient material, such as an organic thermoplastic composition, having a pair of complementary claws projecting from opposite ends in such manner that a pair of parallel logs may be snapped into each pair of claws and held in position therein. In this manner a series of logs may be assembled into selected formations, such as an assembly in a single plane or in planes at an angle or in other geometric formations. Toy houses, bridges, vehicles and many other articles may thus be constructed.
To increase the versatility of the set, openings may be provided in the connectors between and transverse to the direction of the logs gripped by the claws. Such openings permit the mounting of rods to serve as axles of an assembly forming a toy vehicle or as cross beams or for other purposes. As the connectors are generally cast or molded of plastic material, the formation of a hole or passage transverse to the plane of the logs held by the connectors has heretofore required a core in the mold parts which after molding must be withdrawn from the molded connector in a direction transverse to the direction in which the mold parts are assembled, This greatly increased the cost and complexity of the molds and introduced difficulties in the molding of the connectors.
My present invention provides a connector of the above type having the equivalent of a hole transverse to the direction or plane of the logs gripped by the claws of the connector without the necessity of a transverse core.
In the connector of my invention, I provide three recesses extending into the connector between the pairs of claws alterately in opposite directions and in side by side position and transverse to a plane through the logs gripped by the connector. These recesses overlap so that they form alternate off-set halves of a passage or hole through the connector transverse to the plane of the logs. Preferably the inner ends of the recesses are rounded to a semi-cylindrical curvature on a common axis so that the recesses define a cylindrical passage formed of semi-cylindrical ofi-set halves on a common axis. Consequently a shaft or cylindrical rod inserted through this passage is held virtually in a cylindrical hole.
This connector may be molded in a pair of complementary mold halves, one half having a mold cavity to mold an upper half of both pairs of claws and the two outer recesses and the other half having a complementary cavity to mold the other half of the pairs of claws and the intermediate cavity. When the mold is closed, the claws and recesses are formed in the plastic material as described above and the mold halves may be opened in the direction of the recesses.
The invention is illustrated, by way of example, in the accompanying drawings, in which:
FIG. 1 is a perspective view of a connector embodying my invention;
FIG. 2 is a perspective view of the connector taken from the opposite side and showing a pin held in the complementary recesses;
FIG. 3 is a plan view, on a smaller scale, of the con- 3,221,439 Patented Dec. 7, 1965 nector looking down on the uppermost side as viewed in FIG. 1;
FIG. 4 is a plan view, similar to that of FIG. 3 but taken from the opposite side from that of FIG. 3;
FIG. 5 is a side view of the connector taken from the right of FIG. 4;
FIG. 6 is a section of the connector taken on line 6-6 of FIG. 4;
FIG. 7 is an end view of the connector;
FIG. 8 is a section on the connector taken on line 88 of FIG. 6;
FIG. 9 is a plan view, inverted, of an upper die for molding the connector;
FIG. 10 is a plan of the lower die of a mold for molding the connector;
FIG. 11 is a side elevation of a toy assembly using the connector;
FIG. 12 is a side view of a log useful with the connector of my invention;
FIG. 13 is an end view of the log; and
FIGS. 14 and 15 are sections on lines 14-14 and 15-415 of FIG. 12.
In the embodiment illustrated in the drawings, the connector consists of an integral mass 12 of molded plastic having a pair of claws 13 and 14 projecting outwardly at one end and a similar pair of claws 15 and 16 projecting in the opposite direction at the other end. In the plan view shown in FIGS. 3 and 4, the claws appear in the form of a broken circle having an opening 17 for the insertion of a toy log. In the particular form shown the inner surfaces of the claws are rounded as shown by the reference number 18 to engage annular grooves in the log. When used for an assembly a log is pressed through the opening 17, the claws springing apart to permit the log to pass through the opening 17 and then springing inwardly to grip the log. If the log has annual grooves the claws grip it to prevent longitudinal displacement.
To provide an opening between the two pairs of logs extending transversely of the plane of the logs a central depression 19 is formed in the connector between the two pairs of claws extending transversely to the plane of the logs and extending past the mid point of the connector and a pair of depressions 20 and 21 are formed, one on each side of the depression 19, from the opposite side of the connector and extending past the mid point of the connector. The depression 19 intersects the side depressions 2t) and 21 so as to form a passage where the side depressions pass or overlap the inner depression thereby forming a passage from one side of the connector to the other. In the embodiment of the invention shown in the drawing the inner ends of the depressions are of cylindricurvature each inner end being hemispherical and the axis of these surfaces is common to all depressions and form virtually a cylindrical passage or opening through the connector.
As shown in FIG. 2, a pin or cylindrical rod 22 may be passed through the cylindrical passage. The rod may have a tight fit in the passage aided by the resiliency of the material of the connector and be held about one half of its circumference by the inner ends of the depressions 2t) and 21 and about the other half by the depression 19. Insertion of the rod or pin is facilitated as an end of the pin or rod may be laid in the inner end of one of the side depressions to align it with the opening and then displaced through the opening formed by the other depressions.
The connector is capable of being molded by a pair of mold parts, for example an upper mold part and a lower mold part. These mold parts alone form the claws and the transverse opening of the connector. An example of such mold parts is shown in FIGS. 9 and ll) of the drawings, FIG. 9 showing an upper part and FIG. 10 a lower part. Thus in FIG. 9 a mold part 23 having a flat face has formed therein a projection 24 from the mold face of semi-cylindrical shape on an axis in the mold face. A cavity is formed in the mold half comprising end portions 25 and 26 on opposite sides of the projection 24 of a shape complementary to one half of the pairs of claws of the connector and symmetrical to the axis of the projection. These end portions of the cavity are connected on opposite sides of the projection by mid spaces 27 and 28.
A complementary mold part 29 having a flat face and a pair of projections 30 and 31 extending therefrom and of semi-cylindrical form on an axis in the face of the mold half. The inner opposed faces of these projections are spaced a distance equal to the axial width of the projection 24 of the upper mold half. The radius of the cylindrical surface of these projections is equal to the radius of the semi-cylindrical surface of the projection 24. A cavity is formed in the lower mold half comprising end portions 32 and 33 of claw shape and complementary to the end portions 25 and 26 of the upper mold part. These end portions of the cavity are joined by a connecting space 34 between the projections 30 and 31. The depth of the connecting spaces of the cavity is greater than the radius of the cylindrical surfaces of the projections 24, 30 and 31 to provide bridging portions 35, 36 and 27, respectively, between the pairs of claws of the connector as shown in FIGS. 1 and 2.
Upon molding a connector the two mold parts may be parted leaving the connector free for removal. Thus the connector may be molded in a mold of simple construction.
The connector of the invention, in use, connects individual logs, such as log 38 .shown in FIGS. 12-15, which are formed with alternating circumferential grooves 45 and projections 46. The cross-sections of the log at the grooves 45 are circular as shown in FIG. 14 to be received in the recesses 19-21 formed in the connectors. The cross-section of the log between the grooves is cruci-form as shown in FIGS. 13 and 15, the projections 46 forming the arms of a cross. The projections are aligned longitudinally of the log so that longitudinal discontinuous grooves 47 are formed.
If a log is dropped or laid on a sloping surface the longitudinal grooves 47 prevent rolling of the logs as these grooves act as flat, non-circular, surfaces of rest for the logs. The material required for the logs is reduced by the spaces of the grooves from that required for a corrugated surfaces in which the cross-section of the portions between the recesses 45 is circular and the cost of material is reduced correspondingly. The grooves also provide a larger surface and a shorter path for the transfer of heat from the plastic during molding and permit the molding time to be reduced.
An example of the use of the connectors and logs is shown in FIG. 11. In the assembly shown in this figure,
three logs 38, 39 and 40 are connected in a single plane by connectors 41, two logs being connected at their ends by a pair of connectors. A parallel group may be similarly connected. The logs have successive annular grooves which the claws of the connectors engage. A pin 42 is passed through the opening formed by the recesses 19, 20 and 2-1 of each connector and a wheel 43 mounted on each pin to form a toy vehicle. A pair of assemblies in parallel planes may be connected in spaced relation by transverse logs, the ends of which are indicated by the reference numeral 44.
Having described my invention, I claim:
1. A connector for toy assemblies which comprises a molded element having at opposite ends means including a pair of claws curved to grasp and hold a pair of parallel toy logs and having between said pairs of claws a series of at least three contiguous recesses extending alternately from opposite sides of said element in directions parallel to the logs grasped by said claws and having respective bottom semi-cylindrical surfaces about a common central axis normal to a plane coincident with axes of said logs, said recesses together lbeing means forming an unobstructed passage for receiving and holding a cylindrical rod extending normal to the said plane, the open sides of said recesses opposite to respective ones of said surfaces defining passage means to permit withdrawal of a forming die in a direction parallel to the logs.
2. The connector of claim 1 in which said molded element is formed of a resilient organic plastic material.
3. The connector of claim 1 in which said claws contract to a neck opening between the ends of said claws.
