embodiments

Hereinafter, the technical solutions of the invention are described in detail by the figures and advantageous embodiments.

As 1 - 4 show contains the device 100 for picking up and collecting tennis balls of the invention, the first drum 130 and the second drum 140 , The first drum 130 can in the second drum 140 can be inserted and it can be extended or shortened as desired. At the end of said first drum are respectively the first drum cover 110 and the second drum cover 120 intended. Usually consist of said first drum 130 , second drum 140 , first drum cover 110 and second drum cover 120 made of plastic, such as PVC or PP, etc. This reduces the weight and the device can be easily taken or transported.

On the first drum mentioned 130 are some attachment positions 131 intended; and on said second drum are some fasteners 141 intended. When picking up the ball or collecting the length of the second drum 140 be adjusted by the rotation. To the length of the whole device for picking up and collecting tennis balls 100 adjust, be suitable mounting positions 131 is selected, and then the second drum is mounted in the first drum. The aforementioned attachment positions are advantageous as a hole-like locking position 131 formed, and said fastening part is designed as a locking nail and positively connected to said locking position. As a rule, the more locking positions are available, the more adjustable lengths are possible. In one embodiment, said locking position and the locking nail are each 5. In another embodiment, said locking position and locking nail are each 8, thereby the length can be adjusted to different body sizes to pick up ball comfortably or take.

There is also a solar cell 111 on the said first drum cover 110 intended; and on said second drum cover 140 a solar charger is provided; For example, it consists of many flexible solar panels 142 to charge external electronic appliances by solar energy or said solar cell provided on said first drum cover 111 charge. On the said first drum cover 110 is also USB interface 112 intended; she is with the solar cell 111 electrically connected to charge various electronic devices, such as mobile phone, etc. So you can charge them while playing tennis. In one embodiment, multiple USB interfaces 112 on the said first drum cover 110 provided, for example 2 or 3.

Please refer 5 ; on said apparatus for picking up and collecting tennis balls 100 are a speaker 200 and an LED indicator 300 intended; The external USB cable of the speaker can be connected to the solar cell 111 connected to the invention to provide energy; the sound of said loudspeaker is made from the two ends of said device 100 For recording and collecting tennis balls sent out, for example, he can play music, etc .. The aforementioned LED display 300 is on the drum of said apparatus for picking up and collecting tennis balls 100 It is also provided by the solar cell 111 provided. The named LED display 300 can be a BLED indicator, it can show the tennis player time, temperature, humidity, etc.

In the mentioned second drum cover 120 Many elastic stop elements (in the figure is not shown) are provided; said second drum cover is in the first drum 130 provided and replaceable.

The purpose of the stop members is not to roll out the ball in the device at the ball pick-up, and the tennis ball in the field is placed in the barrel under the action of human power. The aforementioned second drum cover 120 can be replaced arbitrarily, thereby extending the life of the device for picking up and collecting tennis balls.

Advantageous to the case of the standing device 100 To avoid picking up and collecting tennis balls is a suction cup 121 on the said second drum cover 120 intended; under the suction cup 121 are a compressed air space 122 and an air circulation channel provided (see 4 ). In an advantageous embodiment, one end of said suction cup 121 Small and the other end is great to easily fit in the second drum cover 120 to stick or out of the second drum cover 120 to stick. When using one needs only the mentioned suction cup 121 in the second drum cover 120 plug in, then press the whole device 100 down, the air in the suction cup 121 is ejected through the intended air duct, thereby the whole device 100 firmly attached to the ground. General external force can be the whole device 100 do not fall over. If you want to take the device for picking up and collecting tennis balls, then you need only the device 100 to pick up and pick up tennis balls; by the elastic stop members in the second drum cover 120 the device is moved, the air is immediately in the suction cup 121 occurred, then the device for picking up and collecting tennis balls can be lifted and taken away.

In summary, the tennis ball picking and gathering apparatus of the invention enhances the current technique, extends the life of the tennis ball picking and gathering apparatus; the whole device can pick up balls and take them with them.
