A recreation center in which a number of sporting goods are rented or lent out may be outfitted with one or more sensor devices near one or more of its exits. At least some of the sporting goods provided for rental or lending include embedded loss control devices that are sensed by the sensor devices, such that attempted removal of the sporting goods from the sporting facility is detected by the sensor devices.

Description

FIELD OF THE INVENTION

The present invention relates generally to sporting goods, and more particularly to loss control for sporting goods.

BACKGROUND

Bowling, among other sports and games, enjoys increasing popularity around the world. Many bowlers do not own their own equipment, and instead rent bowling balls and/or bowling shoes from the bowling center at which they play. Such rentals are not only convenient for the player, but also are important for the bowling center. Rentals of bowling equipment generate revenue for the bowling center not only from rental fees but from lane rental charges and from secondary expenditures that may be made by the bowler. However, some players do not return their rented bowling balls or bowling shoes. Instead, they remove those items from the bowling center, either out of absentmindedness or a desire to steal them. For example, bowling shoes are fashionable in some circles, and theft of rented shoes is a convenient way for an unscrupulous person to obtain them. Thus, bowling centers may experience significant monetary losses due to the theft of bowling balls and bowling shoes rented out to bowlers. This problem is not limited to bowling centers, and extends to other recreation centers at which sporting goods are rented or lent out.

SUMMARY

In one aspect of the invention, a loss control device is embedded within a sporting good. For example, a loss control device may be embedded within a bowling ball, within a plug placed at the bottom of a finger opening in a bowling ball, or within the heel of a bowling shoe. The loss control device may be protected by a shock-absorbent substance or mechanism. By embedding the loss control device within a sporting good, it does not interfere with the operation of the sporting good. Further, the loss control device may be embedded within the sporting good in such a way that it is hidden from the user.

In another aspect of the invention, a recreation center in which a number of sporting goods are rented or lent out is outfitted with one or more sensor devices near one or more of its exits. At least some of the sporting goods provided for rental or lending include embedded loss control devices that are sensed by the sensor devices, such that attempted removal of the sporting goods from the sporting facility is detected by the sensor devices. Where the loss control devices are hidden within the sporting goods, not every item of sporting goods rented or lent out need be outfitted with a loss control device in order to reduce the loss of sporting goods from the sporting facility.

DETAILED DESCRIPTION

Referring to FIG. 1, a [0011] loss control device 2 is embedded within a bowling ball 4. The bowling ball 4 may be constructed in two parts, where a core 10 is covered at least in part by a shell 12. Two-part construction of a bowling ball 4 is standard in the art, and details of the construction of an exemplary two-part bowling ball 4 may be found in U.S. Pat. No. 4,461,478, which is hereby incorporated by reference in its entirety. However, the bowling ball 4 may be constructed in a different manner, if desired. For example, the bowling ball 4 may be a unitary structure, or may have three or more parts. The bowling ball 4 may include a thin coating on its outer surface, which may be useful in increasing the coefficient of friction between the bowling ball 4 and a bowling lane. The composition of such a coating and its application onto a bowling ball 4 may be found in U.S. Pat. No. 4,309,377, which is hereby incorporated by reference in its entirety. Such a coating may be considered to be a shell 12 over a core 10.
The [0012] loss control device 2 is embedded in the core 10 of the bowling ball 4. The core 10 of the bowling ball 4 may be formed from rubber, resin or other substance. The loss control device 2 may be introduced into the core 10 of the bowling ball 4 as the core 10 is formed, while the core 10 is in a liquid, semi-liquid or softened state. Although the loss control device 2 is shown at the center of the core 10 of the bowling ball 4 in FIG. 1, the loss control device 2 may be located at any position within the core 10 of the bowling ball 4.
The [0013] loss control device 2 is standard in the art. Examples of loss control devices 2 are given in U.S. Pat. Nos. 4,413,254 and 4,736,207, both of which are herein incorporated by reference in their entirety. The loss control device 2 may be a device capable of receiving an electromagnetic signal and subsequently reradiating an electromagnetic signal to a receiver. The loss control device 2 may be passive, meaning that the loss control device 2 is unpowered and/or does not generate electromagnetic energy on its own. Alternately, the loss control device 2 may be active, meaning that it is powered and is capable of radiating electromagnetic energy of its own accord. If the loss control device 2 is active, then a battery or other energy storage device (not shown) is additionally present within the bowling ball 4 and connected to the loss control device 2. The energy storage device may be periodically recharged by any standard means, such as induction or direct connection to a power source.
The [0014] loss control device 2 is compatible with the process or processes used to manufacture the bowling ball 4. That is, the components of the loss control device 2, or an off-the-shelf loss control device 2, are selected such that the temperatures, pressures and chemicals utilized in manufacturing the bowling ball 4 do not destroy or substantially degrade the performance of the loss control device 2. Degradation of performance need not be measured in individual bowling balls 4, and instead may be measured statistically throughout the manufacturing process. That is, a percentage of loss control devices 2 may experienced degradation during manufacturing, where that percentage is not a substantial percentage of the number of bowling balls 4 produced.
Referring to FIG. 2, the [0015] loss control device 2 is embedded in the shell 12 of the bowling ball 4, rather than the core 10. The loss control device 2 and the shell 12 are configured such that the loss control device 2 does not protrude from the shell 12 or otherwise interfere with the substantially spherical shape of the bowling ball 4. Thus, the loss control device 2 may be curved, particularly if the shell 12 is thin. The loss control device 2 may be connected to the core 10 of the bowling ball 4, such as by adhesive or by one or more connectors, after which the shell 12 is formed over it. Alternately, the loss control device 2 is not connected to the core 10 of the bowling ball 4. More than one loss control device 2 may be placed in the shell 12, if desired. The use of additional loss control devices 2 may be beneficial to maintain the balance of the bowling ball 4.
Alternately, referring to FIG. 2, the [0016] core 10 may represent an existing bowling ball that does not contain a loss control device 2, and the shell 12 may represent a layer deposited on top of the existing bowling ball. In this way, the owner or operator of a bowling center may retrofit existing bowling balls 4 to include loss control devices 2.
Regardless of the number of individual components of the [0017] bowling ball 4, the loss control device 2 is embedded within one of those components. As used in this document, the word “embedded” means that the loss control device 2 is secured to a sporting good such that the loss control device 2 cannot be removed without destroying or damaging the sporting good. The loss control device 2 is advantageously positioned within the bowling ball 4 such that a user of the bowling ball 4 cannot see or otherwise notice its presence. More than one loss control device 2 may be embedded within the bowling ball 4, in order to provide for redundancy or balance, or for other reasons. For example, one loss control device 2 may be embedded in the core 10 of the bowling ball 4, and another loss control device 2 may be embedded in the shell 12 of the bowling ball 4.
Referring to FIG. 3, in another embodiment, a [0018] loss control device 2 is embedded in a plug 6 of material within a finger opening 8 in the bowling ball 4. The finger opening 8 is defined by a surface 9. This embodiment may be used for manufacturing bowling balls 4, or for retrofitting existing bowling balls 4. For example, a finger opening 8 in an existing bowling ball 4 may be drilled deeper into a bowling ball 4 to accommodate a plug 6 without interfering with the space within the finger opening 8 utilized by a bowler's finger. Then, a plug 6 containing a loss control device 2 may be placed at the bottom of the finger opening 8. As one example, the loss control device 2 may be placed within the plug 6 at a location outside the finger opening 8, after which the plug 6 is secured to the surface 9 of the finger opening 8. Such securing may be performed with adhesive, with one or more connectors, or by other structures, mechanisms or methods. The plug 6 may include a threaded opening (not shown) corresponding to a threaded post (not shown) at the bottom of the finger opening 8, such that the plug 6 may be screwed onto the post. The post may instead be located on the plug, and the corresponding opening may be located at the bottom of the finger opening 8. As another example, the loss control device 2 may be connected to the surface 9 of the finger opening 8 by adhesive, with one or more connectors, or by other structures, mechanisms or methods. Then, the plug 6 is formed within the finger opening 8 by any appropriate method. For example, material in a liquid phase may be poured into the finger opening 8, then allowed to solidify to form the plug 6.
The [0019] loss control device 2 may itself be resistant to the shock and/or other forces experienced by the bowling ball 4 in use. Optionally, the loss control device 2 is protected at least in part from shock and/or other forces by at least one force mitigation element (not shown). The force mitigation element may be any structure or mechanism appropriate for reducing the forces experienced by the loss control device 2. As one example, the force mitigation element is a quantity of cushioning material that at least partially encases the loss control device 2. The cushioning material may be rubber or any other appropriate substance. As another example, the force mitigation element is a shock absorber or similar mechanism. The shock absorber may be active or passive. By utilizing a force mitigation element in order to reduce the forces experienced by the loss control device 2, the loss control device 2 itself need not be robust enough to withstand the forces experienced by the bowling ball itself
Referring to FIG. 4, a [0020] loss control device 2 is embedded within a bowling shoe 14. The loss control device 2 may be substantially as described above. It may be advantageous to utilize the same type of loss control device 2 in both the bowling shoe 14 and the bowling ball 4 in order to detect both with a single sensor device, as described in greater detail below. The loss control device 2 may be embedded within the heel 16 of the bowling shoe 14. Alternately, the loss control device 2 may be embedded within the sole 18 of the bowling shoe 14, or placed at a different location in the bowling shoe 14. Advantageously, the loss control device 2 is hidden, such that the renter or user of the bowling shoe 14 cannot determine its presence by casual inspection of the bowling shoe 14.
Referring also to FIG. 5, an [0021] exemplary recreation center 20 is shown. A typical recreation center 20 may be a bowling center. The bowling center 20 includes a number of exits 24, a rental counter 26, and a number of lanes 28. Patrons of the bowling center 20 rent bowling shoes 4 at the rental counter 26, if they are needed. Bowling balls 4 are typically provided without charge to patrons who need them, and are stored on racks 30 or other structures that may be located in proximity to the lanes 28. At least some of the bowling balls 4 and/or bowling shoes 14 used in the bowling center 20 include loss control devices 2 embedded therein, as described above.
One or [0022] more sensor devices 22 are placed in proximity to each exit 24 to the bowling center 20. The sensor devices 22 are configured to detect a loss control device 2. Sensor devices 22, and their use with corresponding loss control devices 2, are standard in the art. One exemplary sensor device is disclosed in U.S. Pat. No. 4,413,254. At least one sensor device 22 may be configured to transmit a signal instead of or in addition to receiving a signal. In this way, the loss control devices 2 utilized in conjunction with the sensor device or devices 22 may be passive rather than active devices. The sensor devices 22 optionally may be connected to a security system (not shown), an alarm, an alarm system, a security system, or any other type of structure, mechanism or system useful in providing security for the bowling center 20. When a patron moves an item containing a loss control device 2 into proximity with at least one of the sensor devices 22, at least one of those sensor devices 22 will detect the presence of the loss control device 2, and provide an alert such as an alarm and/or a signal to a central security system. As an example, one of the sensor devices 22 transmits a first RF signal. When that first signal is received by a loss control device 2, the loss control device modulates, re-radiates or otherwise alters that first signal to a known second signal. The same sensor device 22, and/or at least one other sensor device 22, receives that second signal. The second signal is known to indicate the presence of a loss control device 2 in a particular location relative to the sensor device 22. Upon detection of that second signal, the sensor device 22 provides a suitable alert. The form of the alert is not critical to the invention. The sensor device 22 may sound an alarm, emit a noise, flash a light, or perform another activity to warn the patron that he or she has attempted to remove at least one item containing a loss control device 2 from the bowling center 20.
In order to provide effective loss control in the [0023] bowling center 20, it is not necessary to outfit each and every bowling ball 2 and/or bowling shoe 14 with a loss control device 2. Rather, a loss control device 2 may be hidden within each of a selected number of bowling balls 2 and/or bowling shoes 14 that are to be rented or lent out, such that the presence of the loss control device 2 is not apparent to the user. Because the loss control devices 2 are hidden within the bowling balls 4 and/or bowling shoes 14, patrons will not know whether any particular bowling ball 4 or bowling shoe 14 contains a loss control device 2. Thus, a potential thief will be less willing to risk stealing sporting goods, as the thief will be unaware of the proportion of goods containing loss control devices 2, and thus unaware of the probability that his or her theft will be detected by at least one sensor device 22. Thus, the likelihood that the removal of any particular item from the bowling center 20 will be detected is related to the proportion of those items within which loss control devices 2 are hidden. Alternately, every bowling ball 4 and/or bowling shoe 14 within the bowling center 20 that is to be rented or lent out may be outfitted with a loss control device 2.
While the invention has been described in detail, it will be apparent to one skilled in the art that various changes and modifications can be made and equivalents employed, without departing from the present invention. For example, while bowling equipment and centers are described above with regard to exemplary embodiments of the invention, the present invention may be used to prevent theft of sporting goods used in other sports, particularly where that equipment is rented out or lent to participants. For example, the present system may be utilized to prevent the theft of putters from a miniature golf course, rented clubs, golf bags or carts from a golf course or driving range, roller skates from a roller rink, ice skates and hockey sticks from an ice rink, or bats from a batting cage. It is to be understood that the invention is not limited to the details of construction and/or the arrangements of components set forth in the above description or illustrated in the drawings. Therefore, the invention is not to be restricted or limited except in accordance with the following claims and their legal equivalents. [0024]
