Description:
Golf ball treatment device

The present invention relates to a golf ball treatment device for treating a golf ball by means of a radiation process for bringing an additive in a wall of the golf ball into an excited state so that after the treatment the golf ball is luminescent.

It is known in the golf world to make use of golf balls with luminescent properties, either by means of an internal light source in the ball or by means of a luminescent outer layer. Such a luminescent outer layer has significant drawbacks in practice however because the light intensity thereof is usually too low for practical use with sufficient convenience. The drawbacks in respect of convenience arise on the one hand from impractical methods of irradiating the golf balls in order to activate luminescent properties and on the other from the resulting limited quality of the irradiation, whereby too little light emission is obtained from the balls for a practical purpose of use.

In order to increase such a convenience the pre ¬ sent invention provides a golf ball treatment device for treating a golf ball by means of a radiation process for bringing an additive in a wall of the golf ball into an excited state so that following the treatment the golf ball is luminescent, the device comprising:

- a housing,

- a holder, such as a tub, which is arranged in the housing for the purpose of holding at least a golf ball, preferably one golf ball, the holder preferably be ¬ ing accessible from an upper side thereof,

- closing means such as a cover,

- a predetermined number of radiation sources such as LEDs,

- control means for controlling the radiation sources, the control means preferably comprising a printed circuit board, wherein

- the device comprises moisture barrier means for forming a moisture barrier between the holder and the other contents of the housing.

An advantage of such a golf ball treatment device according to the present invention is that the golf ball can be provided during play with a treatment for providing luminescence, in particular photoluminescence, with a very high user convenience. The device can be manufactured in advantageous manner by means of such a construction, wherein a high user reliability is also realized in a va- riety of weather conditions, conditions of use and storage conditions of the device. The device is very robust.

In a golf ball treatment device according to a first preferred embodiment the radiation sources are arranged on the outer side of the holder, preferably wherein the radiation sources are arranged in a predetermined number on a radiation source printed circuit board, more preferably wherein the radiation sources can be coupled per predetermined number to the control means, preferably by means of a plug-in connection, wherein an applied num- ber of radiation source printed circuit boards preferably lies in the range of 2-8, more preferably in the range of 3-6, and is more preferably 4 or 5.

It is advantageous in such a preferred embodiment that radiation sources are protected from contact with the ball and contact with fouling from outside. Such a device can also be cleaned in advantageous manner in that only the inner surface, at least the side of the holder in con ¬ tact with the ball, of the holder need be cleaned. Of fur- ther advantage is that placing a fouled ball in the holder, a regularly occurring situation during the game of golf, will further not result in fouling when such a device is applied.

An intensive irradiation of the golf ball is also realized in advantageous manner while applying a minimal number of radiation sources.

At least a part of the wall of the holder more preferably takes a transparent form here. Hereby realized is that a high light output can be combined with the structural advantages of the construction.

In a further preferred embodiment the holder com ¬ prises positioning means, such as preferably protrusions, pins or ribs, for positioning the golf ball relative to the radiation sources, preferably wherein the number of positioning means lies in the range of 2-8, more prefera ¬ bly in the range of 3-6, and is more preferably 4 or 5. An advantageously achieved result hereby is that the positioning of the ball can be optimized in relation to the number of radiation sources applied.

In a further preferred embodiment the holder in the golf ball treatment device comprises actuating means preferably arranged in a bottom wall thereof and prefera ¬ bly attached thereto by means of secondary moisture barri- er means, for the purpose of actuating golf ball detection means, such as a switch co-acting with the control means. The placing of a golf ball in the holder can be detected in advantageous manner by means of such actuating means and the device can be activated on the basis thereof.

In alternative manner the device comprises for this purpose interruption actuating means for detecting an interruption of the actuation of golf ball detection means, such as by means of the golf ball. In a further preferred embodiment the device comprises a movement assembly, such as a rotation assembly, preferably comprising a drive by means of an electric mo ¬ tor, for rotating the golf ball relative to the radiation sources. It is hereby possible to suffice with a relative ¬ ly small number of radiation sources.

In order to direct more radiation at the golf ball the device more preferably comprises a reflective wall, preferably a reflective wall substantially surrounding the holder, or a reflective holder wall. Using such a reflective wall realizes that radiation missing the golf ball or radiation reflected from the golf ball can reach the golf ball again. A higher effective efficiency of the emitted radiation can hereby be realized.

The device more preferably comprises closure de ¬ tecting means for co-action with the control means for the purpose of detecting a closed state of the closing means. Using these the device can for instance be switched on at the moment the golf ball is enclosed.

The device more preferably comprises an induction circuit for charging an energy source such as a battery by means of induction. An advantage hereof is that, when a battery is applied, it can be charged in wireless manner. In alternative manner a wired charging function is provid- ed.

For the purpose of an automatic actuation thereof, the device more preferably comprises a golf ball depressor, preferably co-acting with the actuating means. This is preferably embodied as a block in the closing means or cover. The golf ball can hereby be clamped be ¬ tween this golf ball depressor and the actuating means at the bottom of the holder.

The device more preferably comprises attaching means, such as comprising a bracket, for attaching the device to an attachment position, such as on a golf cart or a golf bag. The device can hereby be applied in very ad ¬ vantageous manner while on the move or when used during a game of golf. The convenience of use is increased when during the short walk from a hole to the following tee the user can easily place the ball in a device for recharging of the luminescent function.

The device also preferably comprises for this pur- pose time switch means for activating the radiation sources for a predetermined time. Said walk from a hole to the following tee usually takes one to several minutes, whereby it is advantageous that the device is firstly suitable for sufficient charging of a golf ball during this period of time, but also that the device switches on and switches off automatically within this period of time so that the user can take a golf ball along in the holder without further action or thought.

For the purpose of a higher radiation efficiency in the direction of the golf ball the device preferably comprises an inward oriented, such as reflective or dif ¬ fusely reflective wall for reflecting light directly or indirectly in the direction of the golf ball.

The holder in the device more preferably comprises in top view 3-6 substantially rod-like, inward extending positioning ribs. The holder is more preferably supported along an upper edge thereof.

For the purpose of an advantageous and simple placing of the radiation sources the device preferably comprises positioning channels which are preferably ar ¬ ranged in a wall of the holder for placing therein of respective radiation source printed circuit boards. This achieves not only that the circuit boards can be placed in simple manner but also that they can be placed and arranged in optimal orientation relative to the ball.

Radiation sources more preferably comprise LEDs with an emission angle which is adapted to the distance from the golf ball or the positioning means. The purpose here is that the maximum radiation reaches the golf ball so as to enable a maximal result to be achieved with mini ¬ mal radiation sources. It is advantageous here that power consumption is also optimized relative to a result.

In a further preferred embodiment the device, preferably the holder, comprises lens means for directing radiation in the direction of the golf ball. This is a further measure for optimizing the efficiency of the radi ¬ ation in the direction of the ball with minimal power con- sumption.

Further advantages, features and details of the present invention will be described in greater detail hereinbelow on the basis of one or more preferred embodiments with reference to the accompanying figures. Similar, though not necessarily identical components of different preferred embodiments are designated with the same refer ¬ ence numerals.
