Definitions
- This invention relates to the field of propulsion and steering mechanisms for toy boats and the like, and in particular it relates to an electrically driven device for actuating a cam to steer a simulated outboard motor for a toy boat and simultaneously to provide propulsive power through the simulated outboard motor to a propeller.
- the Prior Art Toy outboard motor boats of the type disclosed in U. S. Pat. No. 3,528,195 include a hull in which batteries are located and a simulated outboard structure that houses an electric motor connected to the batteries to receive electric power from them.
- the motor may be pivoted by hand from one position to another, but this only determines whether the boat will go straight ahead or will turn left or right to make large or small circles. Once the boat has been released, there is no further control over it until it is recaptured, and it simply follows the simple pattern repetitively.
- Another object is to provide a toy boat with a simulated outboard motor separable from the hull and having propeller drive means that engage power means in the hull when the simulated motor is attached thereto.
- Still a further object is to utilize a cam mechanism similar to that in the aforesaid US. Pat. No. 3,600,851 but with different means connecting the motor, to the cam to control the steering of a toy boat while utilizing the one inboard motor to rotate both the steering cam at relatively low speeds and an outboard, steerable propeller turning at a relatively high speed.
- the boat has a tiller-receptacle at its stern connected to the cam by a pivotal cam-follower to pivot the receptacle back and forth according to the convolutions of the cam.
- the receptacle has a noncircular opening to receive a support post of matching shape on the underside of a simulated outboard motor.
- gear means within the shell of the simulated motor are gear means, one of which extends through the front of the shell to mesh with a gear driven by the motor in the hull.
- the rest of the gear means in the shell drive a propeller from the motor mounted in the hull.
- the motor turns the propeller at a high enough number of revolutions per minute to cause the boat to move at relatively high speed.
- the reduction in the gear toy causes the steering cam driven by the same motor to turn at a relatively low speed so that the boat can move a substantial distance along each heading determined by the convolutions of the cam.
- FIG. 1 is a perspective view of a toy boat constructed according to the invention.
- FIG. 2 is a top view of the hull of the boat in FIG. 1 with the deck removed to show the motor, gearbox, and cam.
- FIG. 3 shows the cam-follower steering means used in the mechanism in FIG. 2.
- FIG. 4 shows a side view of the gearbox and cam of FIG. 2.
- FIG. 5 is a top view of the gearbox and cam of FIG. 4 with some of the parts broken away to show constructional features more clearly.
- FIG. 6 is a cross-sectional view of a simulated outboard motor as used in the boat in FIG. 1.
- the boat 11 shown in FIG. 1 includes a hull 12 and a deck 13. The latter is preferably removable to allow access to working mechanism in the hull and, incidentally, to allow decks of different styling to be used on a common hull design.
- a simulated outboard motor At the stern of the boat 11 is a simulated outboard motor.
- the motor has a propeller 16 attached realistically to a vertical support 17 and extending from a housing 18 at the lower end of the support.
- a switch handle 19 extends through the deck 13 and is the means by which the boat 11 can be started and stopped.
- FIG. 2 shows the hull 12 without the deck of FIG. 1.
- Two projections 21 and 22 on the sides of the hull serve as latching means to attach the deck to the hull.
- Both the deck and the hull are preferably made of plastic so that they can look as realistic as possible.
- the plastic hull 11 has sufficient flexibility to allow its sides to be pressed inwardly to allow the projections 21 and 22 to engage matchingrecesses in the deck.
- Power for the boat is furnished by two batteries 23 and 24, which may be of any suitable size, such as the size of penlite cells.
- the batteries are connected by the wires 26 and 27 to a motor 25.
- the wire 26 is connected to one motor terminal 28 directly.
- the other wire is connected to the other motor terminal 29 by way of a simple, single-pole-single-throw switch 31 controlled by the handle 19.
- the motor 25 is mounted on a speed-reducing gearbox 32 and is'connected to the gears in the gearbox by a gear on the shaft 30.
- the gears in the gearbox are connected finally to a shaft 33 on which a cam 34 is mounted.
- the shaft 33 has diametrically opposed ears 36' and 37 that fit through slots 38 and 39 in the cam 34.
- the cam 34 can then be turned slightly to cause the ears to move on top of recessed portions of the cam. In so doing the ears 36 and 37 are forced past two small projections 41 and 42 that prevent the cam 34 from working loose on the shaft 33.
- a cam-follower 43 has a goose-neck end with a rounded nose that is pressed against the cam surface to respond to the convolutions of that surface.
- the camfollower 43 is connected to a tiller-receptacle 44 at the stern.
- This receptacle has a square recess 46 to receive a similarly shaped support post of the motor 14 (FIG. I).
- FIG. 3 shows the cam-follower 43. At one end is an arm 47 with a goose-neck end. The tip 48 is rounded to minimize wear of the surface of the cam 34.
- the fol lower 43 has a central pivotal support 49.
- At the end of the follower that faces the stern of the boat is an open bridge 51 with a central post 52 extending from it on the side that faces downwardly when the follower is in operative position in the boat. This post actuates the tiller receptacle (FIG. 2) to steer the boat.
- the boat changes from one heading to another in accordance with the convolusions of the cam surface, and the length of time that the boat follows any one heading is determined by the speed of rotation of the cam and the distance along the periphery of the cam from one end to the other of a constant radius portion.
- FIGS. 4 and show the gearbox 32 and associated parts.
- the box has a housing comprising a lower plate 53 on which are several rigid shafts 54 56 to support gears and pinions 57 65.
- Each of the gears is identical and, except for the gear 65, is moulded of plastic with an associated pinion. The latter are also identical, so that the gear-pinion sets are interchangeable.
- Each of the shafts 54 56 has a shoulder that allows the gearpinion sets to slide down to the proper level.
- the gear 57 and its associated pinion have to be put on first since they are at the lowest level.
- the gear 57 meshes with a gear on the drive shaft of the motor 25 (FIG. 2) and the remainder of the gears and pinion mesh in their numericalorder.
- the final gear 65 drives the shaft 33 on which the cam 34 is mounted.
- the cam follower 43 is pivotally mounted on the shaft 56.
- the pin 52 fits in a slot 67 formed in a projection 68 that extends from the tiller-receptacle 44 to pivot the latter in response to movement of the cam follower 43.
- the latter is controlled by the relatively slowly rotating cam 34.
- the movement of the boat is normally along a closed path because the convolutions of the cam 34 are normally symmetrical.
- the simulated motor 14 includes a molded plastic shell 69 that has integral bosses 71 and 72 to guide the endsof gear shafts 73 and 74.
- a support shaft 75 that has a square cross section is non-rotatably attached to the shell 69 and fits into the square receptacle 46 of the tiller-receptacle 44. The shaft 75 thus supports the motor 14 on the stern of the boat and provides the necessary steering coupling.
- gears 76 and 77 are meshed together and are supported on the shafts 73 and 74.
- the gear 76 is loose on its shaft and extends through the front of the housing 69 to engage a gear 78 (FIG. 2) on the motor 25.
- This gear is preferably on the other end of the shaft 30 from the gear connected to the gearbox 32.
- the gear 77 is rigidly attached to its shaft 74 to rotate the latter.
- a pair of bevel gears 79 and 81 in the housing i8 couple the shaft 74 to the propeller 16.
- the boat When the deck 13 is in place and support shaft of the motor 14 is in the tiller-receptacle 44, the boat is ready to run and to follow any path defined by the cam 34.
- the switch handle 19 can easily be reached to start and stop the motor, and, as stated, a different cam may easily be inserted to cause the boat to follow a different path.
- a toy boat comprising:
- a pivotally mounted tiller comprising a post mounted substantially vertically in said hull and having a non-circular receptacle in the end thereof;
- detachable propulsion means connectable to said tiller to be pivoted thereby and comprising means to engage said motor drive means when said propulsion means is connected to said tiller, said propulsion means including a support post of matching non-circular cross-section fitting into said receptacle whereby pivoting of said tiller causes pivoting of said propulsion means.
