Abstract

A playing field for cars guided by hand. The playing field consists of a plurality of rectangular plates (1) on which drive tracks (2) recessed like grooves are delimited by areal sections (3) not intended for driving and in which the plates are designed for mating engagement at their sides for joining the individual plates (1) together to form a larger travel course. The plates (1) can also be arranged one over the top of another plant by means of spacing holders (7). Insertion holes (6) for additional toys are provided on the plate (1).

Description

INTRODUCTION AND BACKGROUND

The present invention relates to a playing field for cars guided by hand.

Quite a large number of toy cars are offered for children which have an essentially similar size, e.g., a Matchbox or SIKU brand toy cars. The children drive around with these cars in an environment which is imaginary or marked by other toy parts while the cars are guided by hand along more or less given paths and are stopped or parked as desired.

An object of the invention is to make a playing field available for this purpose which is as versatile as possible in its use and which can, in particular, also be composed of and expanded with individual parts suitable in their size for children.

SUMMARY OF THE INVENTION

The above and other objects of the present invention can be achieved with a child's playing field which is characterized by a plurality of plates which can be joined together and on which recessed, groove-like drive tracks are delimited by areal sections or regions not intended for driving and in which laterally arranged means for joining the individual plates together to a larger travel course are provided in the form of a toy system.

The plates can have any outer contour which permits a joining together of a plurality of whether to form a larger surface area structure. Thus, for example, a hexagonal honeycomb structure is possible. However, it is desirable if the plates have a generally rectangular shape.

The present invention is based on the consideration of offering a playing field for children which they can join together in a self-acting and independent fashion and whose individual plates can replace each other so that new playing fields with other street layouts can be created over and over again. The playing field can be in the general overall shape of a board or panel made up of sections that fit together. The drive tracks formed to be recessed in the plates serve to guide the toy cars and the area sections acting as boundaries to the drive tracks as their edges can be viewed as curbstone edges in as far as they imitate a reality able to be experienced by children. The area sections are raised with respect to the driving path or roadways.

The plates can preferably consist of wood, that is, solid wood, plywood or chip wood, in which case the drive tracts are produced by material removal, e.g. by milling. Plates consisting of plywood or laminated wood are especially attractive optically as their structure appears in an optically advantageous manner at the curbstone edges, which are preferably obliquely milled. However, the plates can also consist of plastic, in which case the travel tracks can be produced by casting or stamping technology. In addition, it is possible to produce the plates of wood or plastic in two layers, in which case the areal sections or raised portions of the board delimiting the travel tracks are to be placed as plate sections on a continuous base plate.

The plates preferably have such a strength and resistance that a playing field composed of a plurality of plates can be directly stepped on and walked on by children without significant damage to the toy or harm to the child.

Further details are explained in detail with reference made to the exemplary embodiments shown in FIGS. 1 and 2.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 shows a schematic view of a rectangular plate for a playing field; and [0010]
FIG. 2 shows an exemplary embodiment suitable for children. [0011]

DETAILED DESCRIPTION OF INVENTION

Particular emphasis was placed in the view according to FIG. 1 on the working out of the functional relationships. Plate [0012] 1 is provided with two drive tracks 2, 2′ running parallel to the outer edges of plate 1, which tracks are recessed relative to areal sections 3, 3′, 3″, etc. not intended for being driven on. These regions, 3, 3′, 3″, etc. are raised above the plane of the driving paths 2, 2′. Sections 3, 3′, 3″, etc. can function as a lateral guide for the cars to keep the cars in the drive tracks. Recessed drive tracks 2 can either be formed from a thick plate by removal of material or, if the plate consists of plastic, be produced by casting or stamping technology. Moreover, it is possible to produce plate 1 from a continuous base plate 1 a and separately produced areal sections 3 a which are placed onto base plate 1 a and connected to it, preferably by adhering or other means of fastening.
Plate [0013] 1 is provided on its edges with connection means 4 consisting in the exemplary embodiment shown of a plurality of projections 4 a and recesses 4 b which are dovetailed in their cross section. It is readily apparent that in this manner any desired number of plates can be joined together with each other in mating engagement and the playing field can assume any desired size. Insertion plug holes 6 for accessory parts are provided in the raised sections 3.
Street configurations which are not strictly orthogonal or rectangular, or at right angles, are provided in the embodiment according to FIG. 2. The entire travel course can be made more varied by means of rounded-off parts and drive tracks running in curves. However, this embodiment does not involve the possibilities of production for plates [0014] 1 cited in the explanation of FIG. 1. The grid of insertion holes 6 provided in the exemplary embodiment according to FIG. 1 must naturally agree with how areal sections 3 are shaped. In other words, insertion holes 6 can only be realized where areal sections 3 are present. Accessory toys in the form of barriers 9, trees 10, pedestrians 11 or houses 12 can be arranged in insertion holes 6. A very varied shaping of the playing field is also possible here by re-insertion or re-positioning of the accessories. It is furthermore indicated that two plates can be superimposed one over the other, in which instance their vertical spaced apart interval is fixed by insertable supports 7, 7′ which hold plates 1 and 1 a together and assure, optionally with other connection means, that a stable playing filed with two or more stories or levels is created. The transition from one driving level to the other can be established by foldable or binged ramp 8.
Connection means [0015] 5 attached to the edges of plates 1, 1 a, are designed here like projections 5 a and recesses 5 b known from puzzle games and enable interlocking connection.
Of course, other connection means suitable for children can be also provided for joining plates [0016] 1 together, e.g. ones like those known from wooden rails. Moreover, for the case in which no flat bearing area is available for the playing field means for the reciprocal fixing in height of plates 1, e.g., in the form of fixing pins and bores arranged in the joining edges of plates 1 can be provided in accordance with the type of connection means. Such insertion connections can also be the connection means themselves at the same time.
Finally, it is self-evident that a certain grid dimension must be maintained for the arrangement of recessed [0017] drive tracks 2, connection means 4,5 located on the sides and of supports 7 in order that drive tracks 2, 2′, etc. fit each other at the transition point from one plate to the other. The edge lengths of plates 1 can serve thereby as the base grid. A further modification results from the fact that the arrangement of drive tracks 2, 2′, etc. connection means 4,5 and supports 7, 7′ is selected in such a manner that the plates can also be arranged to be offset by half an edge length to each other.
Further variations and modifications will be apparent to those skilled in the art from the foregoing and are intended to be encompassed by the claims appended hereto. [0018]
German priority application 298 05 208.3 is relied on and incorporated herein by reference. [0019]
