Each terminal block 14A-14F is secured to or otherwise associated with a respective one of the power tools 10A-10F and electrically connected to a respective one of the power tools 10A-10F and the respective one of the electrically connected power tools 10A-10F controls one of the receivers 12A-12F each receiver 12A-12F includes a battery pack or any other suitable power source. In accordance with the present disclosure, the power tools 10A-10, the receivers 12A-12F and the terminal blocks 14A-14F may be any suitable number and have any suitable configuration and the terminal blocks may be omitted or may have substantially different configurations depending on the configuration of the power tools and receivers.

In the illustrated embodiment, the power tools 10A-10 ° include women having substantially similar, if not identical, power tool housings 20A-20. Refer to the figures. 2, which shows a representative sample 20A-20 female of each power tool housing, the housing 20A-20F of each power tool includes a working portion 22A-22 female, a handle portion 24A-24F, and mating or otherwise joining together a base a-26F and a cover 28A-28F that may comprise two complementary housings. Each power tool 10A-10F includes working elements, e.g., types, corresponding to the power tool, corresponding electrical power tool elements, e.g., one bit 30A, screwdriver 30B, one bit 30C, one sander 30D, flashlight 30E and saw 30F, and also includes any suitable hardware and electronics for operating the tool elements. The tool elements and hardware, and the electronics may be partially or fully contained within or otherwise associated with the housing 20A-20F of the power tool.

Each power tool 10A-10F may operate at a different voltage. For example, the power tool 10A is configured to operate at 9.6 volts, the power tool 10B is configured to operate at 12 volts, the power tool 10C is configured to operate at 14.4 volts, the power tool 10D is configured to operate at 18 volts, and/or the power tool 10F is configured to operate at 24 volts. The power tools 10A-10 according to other embodiments, F may operate at any other voltage, including any other voltage combination. Each power tool includes an on-off switch 32A-32F.

The 20A-20F defined opposite sides 36A-36FA of the housing F of each power tool of the bases 26A-26 extend along a length of the base, most along the slot 38A-38F. The slots 38A-38F are defined by a pair of ridges 40A-40F extending along the entire length of the side, 26A-26F of the base F of 36A-36, and a pair of outwardly extending rails 50A-50F along the most basal length. The front of the base defines a U-shaped opening 52A-52F and the bottom of the base defines a void 54A-54F adjacent the U-shaped opening for receiving a respective one 14A-14F of the termination blocks.

The receivers 12A-12F comprise females having substantially similar, if not identical, receiver housings 60A-60. Each receiver 12A-12F is configured to engage and charge an operating voltage of F of one or more power tools 10A-10 that is equal to or greater in magnitude than an output charging voltage of the receiver. Accordingly, each receiver 12A-12F also includes a battery pack or any other suitable power source and any suitable hardware and electronic components, and the battery pack to provide power 10A-10 from one or more power tools of the battery pack or other power source may be contained within the f. receiver housing 60A-60F or 12A-12F otherwise associated with the receiver.

Receivers 12A-12F may each provide a different output voltage to charge one or more of power tools 10A-10F for charging, for example, receiver 12A provides an output charging voltage of 9.6 volts, receiver 12b provides an output charging voltage of 12 volts, receiver 12C provides an output charging voltage of 14.4 volts, receiver 12D provides an output charging voltage of 18 volts, receiver 12E provides an output charging voltage of 20 volts, and receiver 12F provides an output charging voltage of 24 volts. Receivers 12A-12F may provide any other output charging voltage, including any other combination of voltages, in accordance with other embodiments. Each receiver includes a power switch 58A-58F.

Each receiver housing 60A-60F includes a top portion 62A-62F defining a rear U-shaped opening 64A-64F and voids 66A-66 continuous with the U-shaped opening F. The 60A-60F of each receiver housing F of the top portions 62A-62 also includes a pair of inwardly extending rails 70A-70F defining upper and lower slots 72A-72F and 74A-74F, respectively, separated by the rails 70A-70F. The upper and lower slots 72A-72F and 74A-74F of each receiver housing are adjacent the gaps 66A-66F. The receiver housings 60A-60F are configured to slidably engage 20A-20F with each of the power tool housings such that the 60A-60F of the receiver housing F of the pair of rails 70A-70 is slidably defined by the base by a pair of slot receptacles 38A-38 from F26A-26F such that the rail 50A-50F powered tool housing receives the F of the receiver housing of 72A-72 from the upper slot and such that the ridge 40A-40 slidably receives the 74A-74F of the receiver of the housing from the lower slot. Thus, each power tool housing 20A-20F is slidably engageable 60A-60 with each receiver housing, except that the present invention also includes means for selectively engaging 12A-12F with each receiver and one or more charging power tools 10A-10F that operate at a voltage equal to or greater than the output charging voltage of the receiver.

Thus, in the illustrated embodiment, all of the power tool housings 20A-20F are of the same or substantially the same configuration, and all of the receiver housings 60A-60F are of the same or substantially the same configuration. Thus, in the illustrated embodiment, all of the power tool housings 20A-20F are slidably engaged 60A-60F with all of the receiver housings F at the base 26A-26 power tool housing F and the receiver housing F at the top portion 62A-62 via the above-described engagement structures. As a result, a kit according to the illustrated embodiments of the present disclosure may be easier and less costly to manufacture than other kits or components of different types and voltages of power tools and receivers or other components, and may also provide other usage and storage advantages.

While, in the illustrated embodiment, all of the power tool housings 20A-20F are configured to engage all of the receiver housings 60A-60F, the present disclosure also includes means for selectively engaging each of the receivers 12A-12F and charging only one or more of the power tools 10A-10F operating at a voltage equal to or greater than the output charging voltage of the receivers 12A-12. In the illustrated embodiment, for example, the snap and charge device including the terminal blocks 14A-14F and the slots 80A-80 are defined by the receiver housing ë 60A-60E, and the 20A-20F of the power tool housing F and the 60A-60F of the receiver housing F of the top 62A-62 of the aforementioned snap features 26A-26 of the base may further include contact pads 82A-82F, which may incorporate any suitable structure, for contacting the terminal blocks 14A-14E, with which each terminal block 14A-14F is associated with each power tool 10A-10F. Each of the terminals 14A-14F is received by a corresponding void 54A-54F in the base of the power tool 10. a-10F and a base that is fixed to any suitable means.

The terminal blocks 14A-14F and slots 80A-80F are configured such that each terminal block is engageable and chargeable with only one or more of the receivers 12A-12 having an output voltage charged to be equal to or less than the maximum operating voltage of the power tool 10A-10F to which the F terminal block is secured. Each terminal block 14A-14E includes a bottom rib 90A-90 that can receive E in one or more slots of one or more corresponding receivers 12A-12E to engage the one or more receivers, but the position of the ribs of each terminal block depends on the E to which the operating voltage terminal row of the power tool 10A-10 is secured. The terminal block 14F does not include any ribs 90 and the receiver housing 60F does not include any slots 80, thereby allowing the power tool 10F to be engaged with all of the receivers 12A-12 but the receiver 12F cannot be engaged with any of the power tools 10A-10E. Each terminal block 14A-14F also includes contacts 94A-94F.

The positions 80A-80F of the slots are dependent on the voltage provided by the receivers 12A-12F. Additionally, the receivers 14A-14d may have more than one slot, such that the receivers also engage power tools having an operating voltage greater than the output charging voltage of the receivers. Thus, in the illustrated embodiment, the terminal block 14A-14F associated with each power tool 10A-10F engaging only the receptacle 14A-14F has an output charging voltage equal to or less than the operating voltage of the power tool, and as a result, each power tool is engaged and may be charged by having only the output charging voltage, i.e., equal to or less than the voltage at which the receiver is operated.

Fig. 5A-5F provide a diagram of the location examples of ribs 90A-90E with the respective terminal blocks 14A-14E and the corresponding receivers 12A-12 in slot locations 80A-80E shown at E. 1. Figure (a). Fig. 5A shows the 9.6V power tool 10A engaged with and charged by the receptacle 12A including the 9.6V battery pack, and also shows the position of the rib 90. The first corresponds to the power tool 10A and the receiving rib 90A of the receiver 12 of one of the time slots 80 the receiver 12A includes the other slot 80A and, therefore, also engages and recharges the other power tool 10B-10 th.

FIG. 5B shows the 12V power tool 10B engaged and being charged 12B by the receiver, which includes a 12V battery pack, and also shows the rib position 90 associated with the power tool B11B and one of the time slots 80B. the receiver 12B of the receiver 12B receiving the rib 90B includes the other slot 80B and, thus, also engages the receiver 12B with the other rechargeable power tool 10C-10F not engaged with the power tool 10A because the operating voltage 10A of the power tool is less than the output charging voltage 10B of the receiver.

Fig. 5C shows a 14V power tool 10C engaged with and charged by a receptacle 12C including a 12V battery pack, and also shows the location of one of the ribs 90C and slots 80C associated with the power tool 10C. One of the receptacles 12C receives a rib 90C. The receiver 12C includes other slots 80C and thus may also engage and charge other power tools 10D-10F. The receiver 12C cannot engage the power tools 10A-10B.

Fig. 5D shows an 18V power tool 10D engaged with and charged by a receiver 12D including a 12V battery pack, and also shows the location of one of the ribs 90D and slots 80D associated with the power tool 10D. The receiver 12D receives the rib 90D. the receiver 12D includes other slots 80D and, thus, the receiver 12D, which may also engage and charge other power tools 10E-10F, cannot engage the power tools 10A-10C because the operating voltage of those power tools is less than the output charging voltage of the receiver 12D.

FIG. 5E shows the 20V power tool 10 in E-engagement and being charged 12E by the receiver, which includes a 20V battery pack, and also shows that the rib location 90 is associated Ë 10E with the power tool and that the receiver 12 Ë of the slot 80E receives the rib 90E. the receiver 12E is also engageable and rechargeable with other power tools 10F. the receiver 12E is not engageable with the power tools 10A-10D because the operating voltage of those power tools is less than the output charging voltage of the receiver 12E.

fig. 5F shows the 24V power tool 10F engaged and charged by the receiver 12F, which includes a 14V battery pack. The power tool 10F does not include any ribs 90 and therefore can engage the 12A-12 Ë of all other receivers since these other receivers have an output voltage charge that is less than the operating voltage of the tool. The receiver 12F does not include any slots 90.

Accordingly, provisions are made for selectively engaging each receiver device 12A-12F to control the charging of the one or more power tools 10A-10F to the one or more power tools. The engagement means includes terminal blocks 14A-14F and receiver structures 12A-12F engage the terminal blocks. The termination blocks 14A-14F can have any suitable configuration according to other embodiments, and, if included, the ribs 90A-90E can have any suitable configuration and other locations according to other embodiments. Similarly, the receivers 14A-14F can have any suitable configuration according to other embodiments, and, if included, the slots 80A-80E can have any suitable configuration, and according to other locations in other embodiments. According to other embodiments of the present disclosure, such selective engagement means may be in any other suitable form.
