Toy vehicle launchers which include a slide that can be drawn back to stretch a rubber band and which can be released to rapidly propel a toy vehicle are entertaining accessories. Toy vehicle launchers generally have a base forming part of the toy vehicle track,side walls for guiding a toy vehicle as it is launched forward, and a slide which must be guided in movement along the launcher and which must be propelled by a spring, rubber band or other means. The ease of use and of marketing the launcher could be greatly increased if it could be easily folded into a small flat package for carrying in the pocket or placement in small packages of other goods as a premium, provided that it could be deployed to a rugged use configuration easily and rapidly. Ruggedness and low cost generally require that a minimum number of easily constructed parts be utilized.

SUMMARY OF THE INVENTION In accordance with one embodiment of the present invention, a toy vehicle launcher is provided which can be economically manufactured and which can be easily changed from a small flat configuration to a longer and taller configuration. The launcher includes a frame with a base, upstanding side and rear walls, a slide which slides through a slot in the rear wall, and a rubber band extending between theslide and the front of the frame for propelling the slide forwardly. The frame is a unitary member with thin web portions forming living hinges between the base and-each of the side walls and end wall, and between forward and rearward halves of the base, to permit folding to a small flat configuration. Retainers formed on the base and side walls enable the side walls to be snapped into a secure upright position on the base, and end wall having other retainers that hold it upright on the side wall. The slide has a long middle portion that slides along the slot in the end wall and a sidewardlyextending rear portion, one edge of the rear portion extending sharply to the side while the other edge isrounded.

The novel features of the invention are set forth with particularity in the appended claims. The invention will best be understood from the following description when read in conjunctionwith the accompanying draw- Ings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a toy vehicle launcher 10 which has been set up to launch toy vehicles onto a track 12. The toy vehicle launcher has only three parts, including a frame 14, a slide 16, that can slide along the length of the frame, and a rubber band 18 that propels the slide along the frame to cause the slide to push a toy vehicle. The launcher is utilized by pulling back on a rear portion 20 of the slide, to the position shown in FIGS. 3 and 4 wherein a front portion 22 of the slide rests against a pair of detents 24 of the frame which have smoothly rising forward portions and sharply falling rear portions. A toyvehicle 26 then can be positioned on the frame in front of the slide 16. If a child then flicks down the rear portion 20 of the slide to release it from the detents 24, the slide will be propelled forward by the rubber band 18, and it will propel the toy vehicle. The launcher 10 can be rapidly disassembled and folded up to the configuration shown in FIG. 2, wherein it. is fiat and has a'length aboutone half the length of the use position. In the folded up configuration of FIG. 2, the launcher can be readily carried in a childs pocket and can be easily packaged either alone or in connection with other merchandise.

As illustrated in FIGS. 7-10, the frame 14 is a unitary member which includes a base 30, a pair of

side walls

32, 34, on either side of the base, and an end wall 36 at the rear end of the base. These

side walls

32, 34 are separated from the base 30 by reduced-thickness regions or

webs

36, 38. The frame 14 is constructed of a material which is flexible in thin sections, such as polypropylene plastic, so that the reduced-thickness regions form living hinges that pivotally connect the side walls to the base 30. A similar living hinge 40 connects the end wall 36 to the base, and still another living hinge 42 extends across the width of the base 30 to divide it into forward and

rearward base portions

44, 46. The integral hinges allow the side and end walls to pivot to a flat configuration, and allow the forward and rearward portions of the base to fold on one another to shorten the device for'storage.

When the

side walls

32, 34 are pivoted to an upright position'on the base for use of the device, the side walls are retained in an upright configuration by eight retainer structures 48, each including an upstanding projection 50 on the base 30 and a web 52 on the side wall. As a side wall such as wall 32 is pivoted upright to the position indicated in FIG. 16, the web 52 passes across the top of the projection 50 on the base. The side wall cannot readily pivot back because the projection 50 resists this. The retainer structures engage one another with a snap sound and feel, to provide a definite indication of the retaining action. The end wall 36 is held upright by means of a pair of

tabs

54, 56 that are received in

slots

58, 60 of the side walls. As shown in FIG. 15, the

tabs

54, 56 have rearwardly facing projections 62 that can snap past the walls of the

slots

58, 60 to provide a definite indication of retainer engagement. In order to set up the frame 16, the end wall 36 is first pivoted upright and then the two

side walls

32, 34 are pivoted upright, with the

slots

58, 60 receiving the

tabs

54, 56 on the end wall.

The slide 16, best shown in FIGS. 11, 12 and 13, is constructed so it can be rapidly installed on the frame and rapidly engaged with the rubber band. The slide has a flat, straight middle portion 70 extending along most of its length between the forward portion 22 and rearward portion 20. A pair of

ribs

72, 74 lie on the lower face of the slide, which help to assure proper installation of the slide on the frame. A pair of tall but

thin projections

76, 78 extend from opposite faces of the forward portion 22, which help to fix the position of the slide on the frame in the storage configuration. The rear portion 20 extends to one side of the middle portion 70, this being the right side as viewed from the rear of the slide. The intersection region where the middle portion 70 merges with the rear portion 20, extends sharply sidewardly at one edge 80 and gradually at the other edge 82. This allows insertion of the slide into the end wall of the frame while preventing accidental removal or great looseness during use. The forward portion 22 of the slide has'a pair of

arms

84, 86 extending away from each other far enough so they can ride along the top of the side walls of the frame. A pair of notches 87 at opposite

sidesforrn projections

88, 90 that can hold one end of a rubber band that urges the slide forwardly along the frame.-

The slide is installed in the manner illustrated in FIG. 15, by projecting the rear portion 20 through a slot 92 formed in the rear wall 36 of the frame. Such projection is accomplished by orienting the slide 16 so it initially extends approximately perpendicular to the length of the frame 14, and then turning the slide while pushing it through the slots. A recess 94 formed along the slot receives the

ridges

72, 74 at-the bottom of the slide, to assure that the slide is not inserted upsidedown into the frame, which would cause the rear portion 20 to extend to the left instead of to the right. After the slide is installed, the rubber band 18 is looped over the

projections

88, 90, and under the forward portion of the frame. As shown in FIG. 5, the frame has a pair of

projections

96, 98 that retain the rubber band thereon when it is stretched. With the rubber band thus installed, the launcher is ready for use in launching a toy vehicle. A child can grasp the rear portion 20 of the slide in his right hand while applying a finger of his left hand to a fingerhold 100 which projects at the rear of the base of the frame, to pull back the slide. The slide can be immediately released, or can be locked on the detents 24 and released by flicking down the rear of the slide.

When the slide is pulled back and locked on the detents 24, and a toy vehicle 26 is laid in front of the slide, the rear wheels 101 of the vehicle will lie between transversely extending ribs 103 formed in the rearward base portion 46, as shown in FIGS. 3 and 3A. The ribs 103 serve to hold the toy vehicle against rolling forward if the launcher is held at a slight angle from the horizontal. The ribs 103 also serve to hold the vehicle pointed downtrack along the length of the launcher, so there is a minimum of rubbing of the vehicle on the

side walls

32, 34 when the vehicle is launched.

After the launcher has been used, it can be readily folded up for carrying in the pocket. To accomplish this, the rubber band 18 is first removed from the slide and frame, and the slide is then removed by the reverse of the insertion method shown in FIG. 15. The frame 14 is then unfolded to a flat configuration by forcefully pivoting the

side walls

32, 34 to a flat configuration with the base, the retainers 50 allow the webs 52 to snap over them when the side walls are forcefully pushed to a flat or horizontal position. The end wall will then be free to pivot down to a position flat with respect to the base. The frame then can be folded in half at the hinge region 42. Prior to folding the frame in half, the slide 16 is installed between the forward and

rearward portions

44, 46 of the base, as shown in FIG. 14. The base has a slot 102 extending in a lengthwise direction through the hinge 42, for receiving the

projections

76, 78 on the slide, so that when the base is folded closed, the slide 16 cannot shift position thereon. When the forward and

rearward base portions

44, 46 are fully closed on one another, they are retained in a fully closed position by a pair of hook like projections, 104, 106, on the forward base portion 44, which engage a pair of hook engagers 108, on the rearward base portion 46. The base portions are thus snapped to a flat configuration with the slide 16 closely held in position therein. If desired, the rubber band can be wrapped around the folded frame. Inasmuch as rubber bands often have a short storage life, the launcher may be sold without a rubber band wrapped around it, it being intended for the child to obtain an ordinary rubber band to power the launcher. The frame can nevertheless retain itself in a compact closed configuration.

FIG. 17 illustrates a toy vehicle launcher constructed in accordance with another embodiment of the invention, wherein several pair of forward hooks 112, 114 and 116 for engaging the rubber band are formed on the side walls 32a, 34a of the frame. These additional pairs of hooks which are spaced at different distances from the rear end of the frame, permit a child to choose different rubber band tensions. This permits a child to utilize rubber bands for a variety of lengths without excessive stretching that could cause breakage or inadequate tension that would result in a low launching speed. In addition, the plurality of hook pairs permits a child to adjust tension for specific situations. For example, a low tension might be used where the track curves without high banking immediately in front of the launcher, to prevent the vehicle from leaving the track, while a high tension might be used where a long straightway track follows the launcher. The launcher of FIG. 17 is otherwise similar to the previously described launcher.

Thus, the invention provides a simple toy launcher having a minimal number of different parts, which can be easily folded to a small flat configuration and opened to a longer and taller use configuration. The only special parts that must be supplied are the frame 14 and slide 16, each of which can be produced at low cost by injection molding. The frame 14, in particular, has several parts that can move relative to one another to permit folding between a flat and a taller configuration, and it securely retains itself in the taller use configuration while providing an entertaining snap sound when setting up, and yet the frame can be formed in a single injection molding operation. The toy launcher is especially useful for launching toy vehicles, although launchers can be constructed for launching other toy devices.
