(54)Title: A WHEEL FOR A TOY BUILDING SET S 22 12 q9 13 (57) Abstract A wheel for use in a toy building set comprises a tire for mounting on a rim with a substantially cylindrical mounting face.
The tire is formed as a ring with a substantially cylindrical engagement face directed toward the rim. The outer surface of the tire is asymmetric about its central plane perpendicular to the wheel axis.
1 A wheel for a toy building set The invention concerns a wheel for use in a toy building set and comprising a tire for mounting on a rim with a substantially cylindrical mounting face.
Various vehicles have always been among the basic structures which it should desirably be possible to build with the interconnectible elements of a toy building set.
As more and more elements for the toy building sets are developed, it is possible to build models which resemble real vehicles to an ever greater degree. Thus, greater requirements are now also made by the consumer since it is now no longer satisfactory to use the same wheel for a model of e.g. a loader tractor and another model of e.g. a passenger car. US-A-3,642,048 describes an example of the structure of a wheel of the above-mentioned type.
o The object of the invention is to provide a wheel structure for use in a toy building set which can be used in connection with various models of vehicles in a manner such .that the wheels contribute to a realistic overall appearance of the vehicle.
Therefore in accordance with a broad aspect of the invention there is provided a wheel for use in a toy building set and comprising a rim having a substantially cylindrical tire mounting face and two rim sides as well as a tire having a substantially cylindrical engagement face facing toward the tire mo-inting face of the rim, said tire having an outer surface which is asymmetric about its central plane perpendicular to the wheel axis, said tire having an annular bead which, when the tire is mounted on the rim, extends inwardly across said rim in the radial direction of the wheel, wherein each rim side is positioned such that the tire can be mounted on the rim with the stafuhiley/keep/specV29419.92j_ 18BA la annular bead proximate either one of said rim sides, thereby allowing the tire to be mounted in either of two alternative orientations.
This object is achieved as stated in the broad aspect because the tire is asymmetric. When the tire is seen in its radial direction, the actual "tread" will be approximately symmetric, while the asymmetry of the tire entails that one side approximately exposes the rim and the hub, while the rim and part of the hub toward the other side are covered. As the tire is turnable, the wheel will seem to have a thin tire from one side, while, when the tire is turned, the corresponding wheel will pretend to have a very thick tire. Thus, with o 0* ,0o o* 0 staf/hlleylkeep/speei29419.92j1 18.4 WO 93/08885 PCT/DK92/00320 2 simple means it is possible for the user to use the same components in two widely different models where the wheels still support the intended general impression.
In the preferred embodiment the tire is made of an elastic material, e.g. rubber, and can be received slidably in the axial direction on the rim. Usually, it is not necessary, but may be expedient in some cases to provide the contact faces between the tire and the rim with an annular bead and a groove to receive the bead.
The wheel part on which the tire is mounted, preferably comprises a cylindrical rim which is integral with a hub via a disc-shaped wheel part. The hub usually also has a cylindrical part for rotatable reception of a shaft part, e.g. shaped as a screw whereby the wheel can be attached to other elements incorporated in the toy building set.
In the preferred embodiment the tire is cylindrical and open at one end, so that the rest of the wheel can be received by movement in the axial direction. The other end of the wheel is partly closed and thus serves as a stop for the axial movement. The partly closed end of the tire may be formed with an internal, annular channel, in which part of the rim is received and retained as a frictional fit against two of the tire faces, partly inwardly partly outwardly. The depth of the channel may expediently correspond to the part of'the rim which extends outside the disc-shaped wheel part.
The disc-shaped wheel part is usually displaced with respect to the central plane of the rim, and stiffening elements in a radial direction may therefore expediently be provided behind the disc-shaped wheel part. These stiffening elements may then expediently serve as a stop for the innermost edge of the annular channel of the tire.
WO 93/08885 PCT/DK92/00320 3 In an alternative embodiment where the wheel shaft is shaped as a screw, this may be attached to the hub in snap manner. It will here be the screw that is turnable with respect to the rest of the wheel. Here too, it is possible to utilize the asymmetric shape of the tire. However, the screw will just be a relatively small single part, which is not always expedient, in particular if the toy building set is intended for small children. It will be appreciated that it is also possible to combine the two above-mentioned structures so that both screw, hub/rim and tire are mutually turnable. Thus, it can also be utilized here that hub/rim may likewise be constructed asymmetrically.
The invention will be explained more fully below with reference to the drawing, in which fig. 1 is a sectional view of a preferred embodiment of a wheel according to the invention, fig. 2 is a sectional view of an alternative embodiment of a wheel according to the invention, fig. 3 is a sectional view of a further embodiment of a wheel according to the invention, fig. 4 shows in perspective how a wheel according to the invention may be used in a toy building set, fig. 5 is a side view of the wheel shown in fig. 1, and fig. 6 is a side view of the wheel of fig. 1 with turned tire.
A wheel according to the invention is shown in fig. 4 where the wheel is adapted for use in a toy building set.
In the shown embodiment the wheel comprises a substan- WO 93/08885 PCT/DK92/00320 4 tially cylindrical tire which is generally designated by the reference numeral 10. The tire 10 has a tread face 9 and a ring-shaped outer face 11 provided at the end of the cylindrical section of the tread face. The tire 10 can be pushed inwardly over a substantially cylindrical rim 12 and be retained as a frictional fit. Via a disc-shaped wheel part 13 the rim 12 is integral with a hub 14 (see fig. in which a shaft in the form of a screw with a shank 16 is rotatably journalled. The screw 16 has a head 18 with a profile such that a tool (not shown) suitable for the purpose can attach the wheel to a building element incorporated in the toy building set. This attachment is provided in that the shank 16 of the screw is formed with a threaded section 19 which is received in a threaded it hole 35 in the building element 30 complementary to the threaded section 19.
Fig. 1 is a detailed sectional view of the structure shown in fig. 4. It will be seen that the head 18 on the screw serves as a stop for the hub 14. It will moreover be seen that the shank 16 of the screw has an annular bead 17 which is asymmetric, so that one side of the bead serves as a guide face in the mounting of the hub 14, while the other side serves as a stop face when the hub 14 has been mounted on the screw. During assembly of the individual parts of the screw it will thus be possible to slide the hub up along the shank 16 of the screw and inwardly over the bead 17. However, backward movement of the hub 14 will not be possible so that the hub 14 is retained rotatably 301 between the head 18 of the screw and the bead 17. As will be seen, the hub 14 constitutes a cylinder tube which, via a disc-shaped section 13, is integral with a rim 12 coaxial with the hub 14. In a preferred embodiment the outer cylinder face of the rim 12 is formed with an annular groove 22 so that when the tire 10 is removed the wheel can be used for other building purposes, e.g. fixing WO 93/08885 PCT/DK92/00320 5 caterpillar treads and the like. The tire 10 itself is shown to be asymmetric, having at its one side a portion which extends beyond the edge of the rim 12 and forming an annular channel in which the edge of the rim 12 is received. The central plane of the tire preferably corresponds to the central plane of the rim, and in a preferred embodiment the tire therefore has a width corresponding to the width of the rim plus twice the thickness of the portion 11. This means that the part of the screw head 18 extending outside the contour of the tire will be constant no matter which way the tire points. For reasons of strength it will often be an advantage that the rim 12 and the shaft 14 are connected with stiffening elements 23 in addition to the disc-shaped part 13. These stiffening elements 23 extend from the hub 14 toward the rim 12 in a radial direction. When the wheel is provided with such stiffening elements 23, the depth of the ring-shaped channel of the tire formed by the portion 11 can correspond to the distance from the disc-shaped part 13 to the outer edge of the rim 12 as well as to the distance from the stiffening elements 23 to the other outer edge of the rim 12.
Fig. 2 shows a second embodiment of the wheel according to the invention in which, like the embodiment shown in fig.
1, the hub 14 is rotatably journalled between a bead 17 and a head 18 on a screw with a shank 16. The hub 14 is here connected with a rim 12 via a disc-shaped wheel part 13. The rim 12 is provided with an annular groove 22, which is somewhat deeper than the annular groove shown in fig. 1, and which is adapted to receive a corresponding annular bead 24 on the internal cylinder face of the tire The tire 10 is preferably of a flexible material, such as rubber, and the bead 24 can therefore be deformed and pushed inwardly over the rim 12 until it is received in the groove 22. The frictional fit explained in connection WO 93/08885 PCT/DK92/00320 6 with fig. 1 will thus be strengthened additionally through the coupling between the tire 10 and the rim 12 achieved with the bead 24. As will be seen, the tire 10 is terminated toward one side, so that the tire termination substantially follows the edge of the rim, while the tire at its other side terminates in a portion 25 i-hat extends inwardly over and covers the tire 12. Like in fig. 1, it will be possible to mount the tire 10 on the rim 12 from both sides so that the tire seems thick like a tractor tire), or thin like a tire for a passenger car).
Fig. 3 shows a third embodiment of a wheel according to the invention, where the hub 14 is connected with the rim 12 via a disc-shaped wheel part 13 and stiffening elements 23. At its one side the tire 10 has a portion 11 extending outwardly over and inwardly below the rim 12. A portion at the other side of the tire 10 extends downwardly over the rim 12 and functions in substantially the same manner as the bead 24. Here too, the tire 10 will be so elastic that it can be mounted on and removed from the rim 12 from both sides. In this embodiment the hub 14 is mounted on a screw with a head 18 and a shank 16. The shank will also have a bead 26 which, in contrast to the bead 17, has two inclined guide faces, thereby making it possible to remove the shaft from the hub. When hub/rim is formed with different front and rear sides, it will be possible to obtain a wheel with four different appearances with both a turnable shaft and a turnable tire.
Fig. 5 is a lateral view of the tire shown in fig. 1, where the wheel has the appearance of a solid tractor tire because of the thick portion 11. From this side it is also possible to see the screw head 18 as well as part of the disc-shaped plate 13. Fig. 6 shows the wheel of fig. 1, where the tire 10 is turned, and it appears from this figure that the wheel seems considerably smaller, e.g. like WO 93/08885 PCT/DK92/00320 7 a wheel for a passenger car or the like. In addition to the relatively narrow tire 10, the figure shows the rim 12 on which the tire 10 is mounted, as well as the discshaped plate 13 which is shown in its entirety. Also the screw 18 is visible.
The invention has been explained above in connection with a hub which is rotatably journalled on a screw by means of which the wheel as a whole can be secured to another building element incorporated in the toy building set.
However, nothing prevents the connection between the screw and the hub 14 from being fixed, i.e. the shaft forms an integral part with both the rim and the hub. When the threaded hole 35 shown in fig. 4 is rotatably journalled as a separate shaft part in the building element 30, this shaft part can be connected with a motor, where rotation of the shaft part can cause the wheel to rotate to propel a vehicle.
