Abstract
Description
- 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.
- 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.
- This object is achieved as stated in the characterizing portion of claim 1 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 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.
- 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 substantially cylindrical tire which is generally designated by the
reference numeral 10. Thetire 10 has atread face 9 and a ring-shaped outer face 11 provided at the end of the cylindrical section of the tread face. Thetire 10 can be pushed inwardly over a substantiallycylindrical rim 12 and be retained as a frictional fit. Via a disc-shaped wheel part 13 therim 12 is integral with a hub 14 (see fig. 1), in which a shaft in the form of a screw with ashank 16 is rotatably journalled. Thescrew 16 has ahead 18 with a profile such that a tool (not shown) suitable for the purpose can attach the wheel to abuilding element 30 incorporated in the toy building set. This attachment is provided in that theshank 16 of the screw is formed with a threadedsection 19 which is received in a threadedhole 35 in thebuilding element 30 complementary to the threadedsection 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 thehub 14. It will moreover be seen that theshank 16 of the screw has anannular bead 17 which is asymmetric, so that one side of the bead serves as a guide face in the mounting of thehub 14, while the other side serves as a stop face when thehub 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 theshank 16 of the screw and inwardly over thebead 17. However, backward movement of thehub 14 will not be possible so that thehub 14 is retained rotatably between thehead 18 of the screw and thebead 17. As will be seen, thehub 14 constitutes a cylinder tube which, via a disc-shaped section 13, is integral with arim 12 co-axial with thehub 14. In a preferred embodiment the outer cylinder face of therim 12 is formed with anannular groove 22 so that when thetire 10 is removed the wheel can be used for other building purposes, e.g. fixing caterpillar® treads and the like. Thetire 10 itself is shown to be asymmetric, having at its one side a portion which extends beyond the edge of therim 12 and forming an annular channel in which the edge of therim 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 thescrew 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 therim 12 and theshaft 14 are connected withstiffening elements 23 in addition to the disc-shaped part 13. Thesestiffening elements 23 extend from thehub 14 toward therim 12 in a radial direction. When the wheel is provided with suchstiffening 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 therim 12 as well as to the distance from thestiffening elements 23 to the other outer edge of therim 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 abead 17 and ahead 18 on a screw with ashank 16. Thehub 14 is here connected with arim 12 via a disc-shaped wheel part 13. Therim 12 is provided with anannular groove 22, which is somewhat deeper than the annular groove shown in fig. 1, and which is adapted to receive a correspondingannular bead 24 on the internal cylinder face of thetire 10. Thetire 10 is preferably of a flexible material, such as rubber, and thebead 24 can therefore be deformed and pushed inwardly over therim 12 until it is received in thegroove 22. The frictional fit explained in connection with fig. 1 will thus be strengthened additionally through the coupling between thetire 10 and therim 12 achieved with thebead 24. As will be seen, thetire 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 aportion 25 that extends inwardly over and covers thetire 12. Like in fig. 1, it will be possible to mount thetire 10 on therim 12 from both sides so that the tire seems thick (e.g. like a tractor tire), or thin (e.g. 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 therim 12 via a disc-shaped wheel part 13 andstiffening elements 23. At its one side thetire 10 has a portion 11 extending outwardly over and inwardly below therim 12. Aportion 25 at the other side of thetire 10 extends downwardly over therim 12 and functions in substantially the same manner as thebead 24. Here too, thetire 10 will be so elastic that it can be mounted on and removed from therim 12 from both sides. In this embodiment thehub 14 is mounted on a screw with ahead 18 and ashank 16. The shank will also have abead 26 which, in contrast to thebead 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-shapedplate 13. Fig. 6 shows the wheel of fig. 1, where thetire 10 is turned, and it appears from this figure that the wheel seems considerably smaller, e.g. like a wheel for a passenger car or the like. In addition to the relativelynarrow tire 10, the figure shows therim 12 on which thetire 10 is mounted, as well as the disc-shapedplate 13 which is shown in its entirety. Also thescrew 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 threadedhole 35 shown in fig. 4 is rotatably journalled as a separate shaft part in thebuilding 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.
