This is the U.S. National Stage of International Application No. PCT/IL2020/050087, filed Jan. 22, 2020, which was published in English under PCT Article 21(2), which in turn claims the benefit of Israeli Application No. 264585, filed on Jan. 31, 2019, which are all incorporated herein by reference.
The present invention relates to the field of sport accessories. More particularly, the present invention relates to a retrieval device for balls, particularly for games.
When playing games that involve the use of balls, users sometimes need to pick up the balls during or after a game, and it can be burdening and tiring. Thus there is a need for a ball retrieval device that will provide an easy and comfortable solution. There are some retrieval devices, but they do not meet the combination of requirements for a height-adjustable retrieval device that allows an easy gathering of balls, which can house a plurality of balls and prevent them from rolling out of the device, until the user enables it by a simple mechanism.
It is an object of the present invention to provide a device that allows for an easy and convenient gathering of balls from a surface.
It is another object of the invention to provide a telescopic device the height of which can be adapted to the user's preference.
It is yet another object of the invention to provide a device that may house a different number of balls according to its height resulting from its telescopic positioning.
It is a further object of the invention to provide a device adapted to stop balls from being discharged after their retrieval, and to allow their discharge easily and at will. Other objects and advantages of the invention will become apparent as the description proceeds.
The invention relates to a ball retrieval device, which comprises: a telescopic tubing assembly suitable to house a plurality of balls; a retrieval mechanism suitable to allow the passage of a ball into said tubing assembly and to prevent its discharge therefrom; a positioning element suitable to cooperate with slotted connecting elements and to prevent the undesired rotation of parts of said telescopic tubing assembly relatively to one another; and a capping element provided with stopping elements, suitable to release balls from the device when said stopping elements are in an open position.
According to one embodiment of the invention, the positioning element is a pin that is located at one part of the device, suitable to slide along rails that are located at another part of the device. The relative movement of the pin along the rail that is located at a different part of the device, form a telescopic movement of the device, allowing length adjustment. This telescopic tubing assembly also comprises intermediate connecting elements suitable to connect two sections having different diameters. Each connecting element is suitable to connect to a different tube with a different diameter, and they are also suitable to connect to one another.
The stopping elements that are provided in the capping elements comprise, according to one embodiment of the invention, elastic snapping strips. The strips can bent and move from an open position to a closed position, wherein an open position is a position that allows the passage of balls, and a closed position prevents balls from passing. The capping elements can also comprise axes that hold the strips and provide them with a rotational movement in order to move from one position to the other.
The retrieval mechanism, according to one embodiment of the invention, comprises inner retrieval components suitable to allow the entrance of balls through one of the openings of the device, and prevent them from passing the other way around.
According to another embodiment of the invention, the inner retrieval components are shaped as teeth, and they are coupled to springs and provided with an axis at one end, suitable to allow said teeth to rotate. According to this embodiment, when pressure is applies at the edge of the teeth that is closer to the axis, the teeth press the spring and fold toward it, but when pressure is applied the other way around, the structure of the teeth and the location of the axis prevent them from moving. This way balls can pass through the retrieval mechanism only in one direction. According to another embodiment of the invention, the inner retrieval components are elastic, suitable to be displaced upon pressure, thus allowing the passage of balls through them when a user applies pressure during the retrieval activity.
In the drawings:
The present invention provides a device for ball retrieval. Although the description refers mostly to a retrieval device for tennis balls, the device is obviously suitable for other types of balls, such as ping-ping or golf balls. In addition, the drawings do not show balls, since when reading the description it is obvious to any person, especially a person skilled in the art, how to apply the device to any type of balls.
As described, teeth 107 can move in some embodiments, but only when pressure is applied on them from the entrance and toward inner tube 102. The edges of teeth 107 that are more distant from opening 108 are designed to prevent the exit of balls from tube 102. The arrangement of teeth 107 side by side along the inner circumference of cap 106 form a blocking structure for the balls that are housed inside tube 102, since the diameter of said blocking structure is smaller than the diameter of the balls. Of course, teeth 107 can be replaced with any other structure that provides the ability to insert balls through opening 108 and prevent them from passing the other way around, and the invention is not limited to any specific structure. For instance, elastic elements can be provided in the circumference of cap 106, which are displaced upon pressure and may have any desired shape.
The insertion of balls through opening 108 into tube 102 can be performed, for example, by placing device 101 on top of a ball and applying pressure downward. This way the ball applies pressure on teeth 107, passing them, allowing them to enter inner tube 102. This way of operation is very comfortable for a user, since he can retrieve balls without bending.

Tube 102 comprises depressed rails 204, also suitable to host pin 202, as slots 203. Rails 204 are aligned with slots 203, and when pin 202 is located inside one of slots 203, it can slide into and along one of rails 204, thus providing a telescopic mechanism: outer tube 103 is connected to element 104 that comprises pin 202. Inner tube 102 comprises rails 204 and is connected to element 201 that comprises slots 203. When connecting elements 104 and 201 and positioning pin 202 inside one of slots 203, in order to operate the telescopic mechanism, one needs to slide pin 202 along rails 204, causing tube 102 to slide inside tube 103.
Second cap 106 comprises additional slots 205, similar to slots 203. The shape of slots 203 and 205 is a corner shape, which provides a locking mechanism. When pin 202 is inserted into the non-longitudinal part of slots 203 and 205, pin 202 is prevented from moving along the longitude axis of device 101, and tube 102 and 103 can no longer move in relation to one another. This state is also referred to as a locked position. When pin 202 is located inside one of slots 203 in a locked position, the device is in its most elongated state, and when pin 202 is located inside one of slots 205 in a locked position, the device is in its shortest state. The device can further comprise additional slots along tube 102, or other locking mechanisms, to provide additional locked positions when tubes 102 and 103 are partially overlapping.
The telescopic mechanism of device 101 and the possibility to lock device 101 at different overall lengths provides a significant advantage, since a user can adjust device 101 according to the number of balls and according to his height. In addition, the ball retrieval mechanism of device 101 provides an easy and comfortable retrieving operation, without the need to bend or make a substantial physical effort.
In addition to the telescopic mechanism and the retrieval mechanism, device 101 also comprises a locking mechanism.
The above description of specific embodiments has been provided for the purpose of illustration and is not intended to limit the invention in any way. Many modification and variations can be effected in the device, without exceeding the scope of the invention.
