Abstract

Nozzle (1) for inflating inflatable objects, e.g. of leisure items such as Air cushions, inflatable boats etc., with a nozzle channel (7) for guiding air and at least one side opening (6) of the nozzle channel.

Description

The innovation concerns an inflatable nozzle of inflatable objects, e.g. of leisure items or air cushions, inflatables etc.

The innovation is based on the task, one Nozzle for To inflate inflatable objects that offer a increased Has pumping power.

This task is accomplished through a nozzle with the features of protection claim 1 solved. Advantageous embodiments the nozzle are in the subclaims 2-11 described.

In the nozzle according to the innovation is a nozzle channel for guidance provided by air, the nozzle channel has at least one lateral opening. When feeding of air used to inflate the inflatable items, this air enters the nozzle channel introduced, at the point where the side opening of the nozzle channel passed, 'and further in the nozzle channel led into the interior of the inflatable object.

Surprisingly is created by the side opening of the nozzle channel no loss of pump power, rather the pump power increases. This significantly reduces the inflation time for inflating inflatable objects.

According to an advantageous embodiment is the side opening designed as a hole and opens out laterally in the nozzle channel.

According to another advantageous embodiment has the nozzle channel a section with a decreasing diameter in some areas. hereby an acceleration of the pumped-in air can be achieved.

When using a check valve an undesirable Escape of air from the inflatable object can be avoided. The introduced into the subject Air therefore remains in the object and cannot escape, even if while there is an interruption in inflation.

The check valve can open different ways known per se and in a special way simple and inexpensive producible embodiment be designed as a flap.

After another advantageous one embodiment is the side opening the nozzle channel, e.g. over a sleeve, coverable. When the cover is moved, the size of the side opening (degree of opening) can be varied. This can cause the suction effect that occurs when inflating varied and amplified or be reduced. So during initial inflation, e.g. on greater degree of opening chosen become. At the final and approaching the end Inflation can increase a larger pump pressure the side opening be reduced or closed entirely. In the opposite case by opening of the side openings an overpressure be avoided in the object to be inflated.

According to another advantageous embodiment has the nozzle channel at least one filter element for air purification of the supplied air, to avoid dirt particles close the through hole.

If the inflatable object is a backflow valve to prevent the accidental escape of air, can the nozzle advantageously an extension on the front for opening a such check valve when inserting the nozzle own in the inflatable object.

After another advantageous one embodiment can the nozzle a thread for attaching tire inflators for accelerated filling have inflatable object.

Further details of the innovation against from the drawing figures. Show it:

1 a longitudinal section of a nozzle with the sleeve open and

2 a longitudinal section according to 1 with closed sleeve.

1 shows a nozzle designed essentially as a round body 1 as a longitudinal section with a thread 2 for attachment to a tire inflator. In the entrance area 3 the nozzle 1 is a filter element 4 intended for cleaning the supplied air. Behind the filter 4 is a nozzle bore 5 provided with a reduced diameter to accelerate the supplied air. Behind it is the lateral (continuous) opening 6 , Following this, the nozzle 1 through the nozzle channel 7 continued, which with a check valve 8th (e.g. a flap).

Then the nozzle narrows 1 to the exit opening 9 , This is followed by a partial extension 11 attached, which can push back the flap located there when inserted into the opening of the inflatable object. On the nozzle 1 there is a sleeve 12 , what a 1 in a pushed back and in 2 is shown in a closed position. In the retracted position after 1 is the opening 6 fully open. In the closed position after 2 is the opening 6 completely closed.

The sleeve 12 can also be adjusted in middle positions to adjust the degree of opening 6 adjust to regulate the pressure building up inside the inflatable object (not shown). The sleeve can also be attached to the nozzle by means of a thread, which at the same time allows fine adjustment, possibly with scaling.
