Abstract

A toy boat which has a motor-driven pump which enables water to be sucked in and expelled through spray jets in imitation of a fire tug. The intake to the pump is arranged in the bottom of the boat to be substantially vertical and this provides for greater stability of the boat when pumping water. <IMAGE>

Description

SPECIFICATION Toy boat The invention relates to a toy boat which is an imitation of a fire tug, with a motor-driven pump, which draws in water through an intake orifice located below the waterline and feeds it to spray jets located on the deck, which spray the water substan tially upwards. In a known toy boat the intake orifice is in the form of a nozzle, located either in the stern or in the bow of the toy boat, so that the water is drawn in roughly in the lengthwise direction of the boat. It has been found that if the water is drawn in along the lengthwise direction of the boat and is expelled roughly vertically upwards, the stability of the boat in the water is impaired.In particular, if these toy boats are, in imitation of fire tugs, having a squat appearance, they tend, as a result of the said flow of water, to rock, and, under unfavourable circumstances, even to capsize.

It is an object of the invention to provide, in a toy boat of the type mentioned, better stability and a better position of the boat on the water.

For this purpose, the invention proposes, in the case of a toy boat of the type mentioned, that the intake orifice should be in the bottom of the boat and should be directed substantially vertically downwards. As a result, the water is drawn into the boat roughly vertically and hence a force directed vertically into the water is exerted on the boat. This force is additive to the force which acts on the boat as a result of water being squirted roughly vertically upwards from the nozzles. Thus, according to the invention, two additive forces directed roughly vertically downwards act on the toy boat. This contributes substantially to stability of the boat in the water and as a result largely eliminates the danger of rocking or even capsizing.

As a further development of the invention, an additional ballast can be present in the interior of the boat, providing an additional force acting vertically downwards on the boat.

In total, the invention results in a better floating position and better position of the centre of gravity of the boat.

An illustrative embodiment of the invention is described below and depicted in the drawing, in which: Figure 1 schematically shows a toy boat according to the invention, in side view, and Figure 2 shows a top view onto Figure 1, after removing the upper part.

The toy boat, shown schematically only, consists of the lower part 1 and the upper part 2 which can, for example, be removably fastened to the lower part. In the lower part 1 there is provided a suction pump 3 which draws in the water through the intake orifice 4 which is directed roughly vertically downwards, and feeds the water, via a hose 5, to the spray nozzles 6 on the deck formed by the upper part 2.

The intake direction of the water is marked with the arrow A and the squirting direction with the arrow B.

Accordingly, a force P1 acting on the toy boat is produced by the intake A and a force P2 acting on the boat is produced by the squirting-out B. Both forces are directed roughly vertically downwards and are therefore additive. As a result, the desired stability and good floating position and position of the centre of gravity are imparted to the toy boat. The waterline is marked 8.

The abovementioned effect of a good floating pos ition and good position of the centre of gravity can be additionally boosted if an additional ballast 7 is present in the interior of the boat, additional to the weight of the pump 3 and of its drive motor. Furthermore, batteries, which drive the motor of the pump 3, and which are not shown in the drawing, are provided in the boat.

It is self-evident that the position of the intake orifice 4, which is directed roughly vertically downwards, in the bottom 1' af the boat can also be elsewhere than the position shown in the drawing.
