BRIEF SUMMARY
BACKGROUND OF THE INVENTION
(1) Technical Field
The invention relates to a device for storing tennis balls under pressure.
(2) Description of the Prior Art
Devices for storing tennis balls are known for example from DE-U-87 02 822. The pump housing of this device is arranged with a very small space right beside the tubular container, and in the inserted state the pump handle ends approximately in the centre of the container. Because of this construction effort is required to hold the container and pumping involves a considerable danger of injury (pinching the fingers between the pump handle and the container).
The same disadvantages beset the device which is known from U.S. Pat. No. 3,888,347, in which the pump housing is arranged immediately adjacent to the container, without a space, and, similarly in this case and when in the inserted state the pump handle ends approximately in the centre of the container.
SUMMARY OF THE INVENTION
The object of the invention, therefore, is to construct a device in which it is possible to hold the device comfortably and easy pumping is possible without danger - and at the same time production is simple and economic.
Accordingly, the subject invention is directed toward a device for storing tennis balls under pressure including a tubular container which is provided with a screwable cover on at least one end. The device further includes a piston pump with a pump housing arranged adjacent to the container and connected to one end region of the container and with a piston which is movable in the pump housing by means of a pump handle. A non-return valve is included which connects the pump pressure chamber to the interior of the container. The device is characterized in that the pump housing, which is constructed as a handle, is also connected to the other end region of the container so that there is an opening for a hand to reach through between the pump housing and a container and in the inserted state the pump handle also projects over the container.
THE DRAWINGS
The invention will be described in greater detail below with the aid of the accompanying drawings, wherein:
FIG. 1 is a longitudinal section through the device,
FIGS. 2 to 4 show sections along the lines II--II, III--III and IV--IV respectively,
FIGS. 5 and 6 show particulars (on an enlarged scale) of the details V and VI respectively according to FIG. 1,
FIG. 7 is a plan view of the detail according to FIG. 6.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The device according to the invention for storing tennis balls under pressure is illustrated in the drawings and comprises a tubular container 1 and a piston pump 2.
The longitudinal axis 3 of the container 1 is bent in the central region of the height of the container so that the upper section 1a of the container 1 extends parallel to the axis 4 of the pump housing 5 of the piston pump 2, whilst the lower section 1b of the container 1 forms an acute angle with the axis 4 of the pump housing 5.
The pump housing of the piston pump 2 is arranged a sufficient distance from the container 1, so that there is an opening 6 for a hand to reach through between the pump housing 5 and the container 1, and--because of the described bent shape of the longitudinal axis 3 of the container 1--this opening 6 widens towards the top.
The pump housing 5 of the piston pump 2 is connected to the container 1 both at the lower end by a common screw thread extension 7 and additionally by a narrow crossbar 8 and also at the upper end by crossbars 9, 10. The pump housing 5 and the container 1 are advantageously produced in one piece from impact-resistant plastic in an injection moulding process.
The container 1 is provided at its upper end with a screwable cover 11. At the lower end the container 1 is closed by a screwable base 12. The diameter of this base 12 is somewhat greater than the sum of the diameters of the container 1 and the pump housing 5, so that the vertical projection of the pump housing 5 lies within the outline of the base 12.
The piston pump 2 contains a piston 13 wh
