Definitions
- the invention relates to a water spray device for children the preamble of claim 1.
- the present invention is based on the object Specify water sprayer for children with the large quantities Water can be splashed safely.
- the water spray toy according to the invention contains a water container, which can be of any size and preferably is movable on wheels. There is one on this water tank Piston / cylinder unit attached, the cylinder preferably is located entirely within the water tank while the end portion of the piston rod with a handle protrudes from the water tank.
- the piston / cylinder unit has a suction line that extends to the bottom of the container extends, and a spray line coming from the water tank leads out.
- the water tank can be part of a tank truck that for example from a child's trolley Tractor is towable.
- the water tank can also become one Fire engines belong, but it is also within the scope of the invention is that the water tank - without wheels - is stationary rests on the floor.
- the piston / cylinder unit is preferred in the fastening position aligned vertically so that it is used to spray the water required pump movement of the piston in a corresponding vertical Direction.
- the water sprayer is operated by a child in the way that it moves the piston back and forth with one hand while it hold the spray line in the other hand. It depends on the strength and speed of the pumping movement depends on how far the water jet is sufficient, with the piston / cylinder unit according to the invention especially because they're in vertical Alignment should be actuable, considerable width is reached depending on the size of the piston / cylinder unit can be about 6 to 10 m. Of course, the water sprayer can can also be operated by two children at the same time.
- the water tank can easily have a capacity of 100 l or more, so that the child is practically inexhaustible Water supply is available. It can be the water spray device according to the invention not only for play, but also for practical and useful purposes, for example to water flowers in the garden. If the local Conditions are such that one connected to a water pipe The hose may not reach remote locations for this purpose Remedy water sprayer according to the invention here.
- the water tank preferably has a tubular extension on its top and that the Cylinder on its upper end wall radially outward protruding cover section, which with a down angled annular edge tightly embraces the approach.
- the approach of the container has a radially inwardly projecting ring wall at its upper edge, which interacts with spring clips or spring arms with which the piston / cylinder unit is locked on or in the shoulder can be.
- each radial protrusions protruding outwards that form the inner ring wall of the approach, while the spring arms with subsequent Handle sections recesses in the lid section Reach through upwards on the outside or in the mounting position.
- the Recesses are dimensioned so that the handle sections Have it pressed radially inward, with the outer protrusions or approaches protrude from under the edge of the ring wall, so that the piston / cylinder unit is pulled out of the neck of the container can be. This can e.g. done for the purpose Refill water in the water tank, if appropriate the neck is the water fill opening of the tank forms.
- the bottom portion of the cylinder can be slightly wider than that remaining cylinder section.
- the suction hose is preferably seated on a nozzle that is approximately in the middle of the bottom section of the Cylinder opens, with a check valve, preferably a Ball check valve that opens the suction opening when the Piston is pulled up, but closes the suction opening, when the piston to release the water down is pressed.
- This spray line preferably runs parallel to the cylinder, i.e. at a distance from this upwards through a recess in the cover section in which it is kept tight.
- Near the the top of the cylinder are in the wall of the cylinder preferably several holes for pressure equalization at the Actuation of the piston.
- the water tank and the piston / cylinder unit exist preferably plastic, although the invention is based on this Material is not limited.
- a water tank 1 is shown purely schematically, which is, for example, one of a children's pedal vehicle towed truck can act.
- the water tank 1 has a vertically upwardly projecting cylindrical Filler neck 2, one in the right at its upper end Has inwardly angled ring wall 3.
- the water tank and the filler neck are preferably made in one piece Made of plastic.
- a piston / cylinder unit 4 sits in the filler neck 2, whose cylinder 5 protrudes into the water tank 1.
- Cylinder 5 sits close to its inner wall, a short one Cup-shaped piston 6 with a molded piston rod 7, the protrudes from the cylinder and at its upper end with a provided in Figure 1 only schematically illustrated handle 8 is.
- spring arms 9 On the outside of the cylinder 5 there are 2 in the upper end region or more spring arms 9 are formed, which are essentially an L-shape have, with the long leg 10 parallel to the cylinder wall 5 extends and this towered above.
- the spring arms 9 are with their short leg 11 on the outside of the cylinder wall 5 molded.
- the long legs 10 of the spring arms 9 protrude from recesses 12 in an annular formed on the upper edge of the cylinder 5 Cover 13 out.
- the recesses 12 are dimensioned so that they allow the long legs 10 of the preferably two opposing spring arms 9 pressed radially inwards so that the outer protrusions on these long Legs 10 are aligned with the cutouts 12. In this condition can the piston / cylinder unit 4 from the filler neck 2 be pulled out.
- the lid 13 has a downward bent at a right angle Ring wall 14 which tightly engages around the cylinder wall 5.
- the water sprayer can also be run by small children can be operated very effectively.
