Detailed Description of Preferred Embodiment(s)

[0072] Throughout this specification, like numerals will be used to identify like features, except where expressly otherwise indicated.

[0073] As shown in the drawings, the mobile charging pod or power tool battery charging station, generally designated by the numeral 1, includes a housing 2, which is divided into a plurality of compartments 3, as perhaps best shown in FIG. 11. Whilst the number of compartments may vary, the illustrated embodiment shows the housing having six compartments 3. Each compartment 3 is adapted to receive at least one power tool and/or battery charger (not shown), as will be described hereinafter.

[0074] A lockable door 4 is associated with each compartment 3. FIG. 12 shows an exemplary embodiment of a door 4, separated from the housing 2, whilst FIGS. 1 to 5 show a plurality of doors 4 attached to the housing 2.

[0075] Each compartment 3 or each door 4 preferably has at least one cutout 5 therein through which, in use, an electrical cord of a respective power tool battery charger is adapted to be provided.

[0076] A plurality of electrical outlets 6 is preferably provided on an outer wall of said housing. Each outlet 6 is adapted to receive a plug of a respective power tool battery charger.

[0077] The outlets 6 may be any form of type of electrical outlet, and may typically be embodied as a mains power supply electrical outlet. The outlet 6 may typically be a single or double GPO electrical outlet.

[0078] In one example form the mobile pod housing is substantially waterproof or weatherproof for protection of the electrical batteries and other electrical products placed in the compartments, and at least one of outlets 6 may be embodied as a weatherproof or waterproof electrical outlet.

[0079] The provision of the outlets/sockets on the outside of the compartments enables the electrical tags attached to the plugs of the power tools to be readily inspected by safety officers or other inspection personnel whilst protection from external environmental elements such as adverse weather conditions.

[0080] In use, after a power tool in installed in a compartment 3, the power cable of the power tool is fed through the outlet cutout 5 in the housing 2 and plugged into one of the electrical outlets 6. The door 4 may then be closed and locked, securely maintaining the power tool in the compartment 3.

[0081] For example, a padlock may be attached to an appropriate padlock attachment orifice. A recess 16 may be additionally provided in the door 4 so that the metal tab of the padlock does not protrude past the overall extremities of the housing 1, and hence is protected from damage.

[0082] A switch 6A of the respective outlet 6 may then be operated by placing it into the on position, such that the charging operation may be initiated.

[0083] As the charging operation occurs, the power tool is visible via openings 7. This provision of the openings 7 facilitates inspection of the tool by the owner of the tool, and/or by others, including by any safety personnel.

[0084] A circuit breaker 8 (see FIG. 13) and/or any electronic circuitry which may be desired to ensure the appropriate safe charging of the power tool(s) provided in the/each compartment may be additionally provided within or on the housing 2, operatively connected to the or each electrical outlet 6. The circuit breaker 8 may be of the type incorporating a resettable switch which may be operated in the event of a tripping occurrence.

[0085] Each lockable door 4 is adapted to be locked by any one or combination of a padlock, a key operated lock, an electronic lock, a smart phone operable lock, a fingerprint or other biometrically operated lock, a keypad operated lock, a combination lock, or any other form of lock. Various preferred types of locks and optional alternative locks will become apparent, depending on the particular installation of the charging station 1.

[0086] Each door 4 is preferably also provided with any one or combination of at least one power cord cutout, at least one ventilation cutouts 7, and/or, at least one inspection window therethrough. These may be designed to be separate purpose-built cutouts, windows or orifices 7, or they can be used for any one or combination of these purposes

[0087] The housing 2 is preferably embodied as a mobile housing, to include at least one wheel 9 or roller thereon, optionally incorporating a locking and/or braking mechanism. This is to facilitate ease of moving the housing 2, when desired, whilst, preventing its movement at other times.

[0088] The housing 2 may alternatively or additionally be mounted on a skid, for use in environments where wheels may not be appropriate. In one example embodiment, the wheels may retract from within the skid such that when suitable, the housing may be rolled on the substrate surface.

[0089] The housing 2 may also optionally include a motor therein for power assisted movement of said housing 2. This is particularly useful if the housing 2 is large and/or heavy, to avoid having to manually push the housing 2 to a desired position, when required.

[0090] Preferably, the housing 2 further includes at least one handle 10. This enables a user to readily grip onto the housing 2, for example when it is desired to move it about.

[0091] The housing 2 may also incorporate at least one lifting eye 11 thereon. This is particularly useful when the charging station 1 is required to be craned onto a building site, particularly if it is installed or removed from a substantially elevated position.

[0092] The charging station 1 may also be adapted to be lifted by a fork lift, and may optionally include a fork lift engagement mechanism thereon. This also facilitates the relocation of the charging station 1 as desired by a fork lift.

[0093] The housing 2 may also optionally include at least one lock down chain point connection 12 thereon. This facilitates the securement of the charging station to a substrate or to another object, to avoid the housing 2, per se, being moved without appropriate authorisation and/or being blown in the event of high winds which may typically occur on a high rise construction site.

[0094] The housing 2 may also incorporate a plurality of compartments 3 formed in any one or combination of at least one column, wherein the compartments are substantially vertically disposed relative to each other, and, at least one row, wherein the compartments 3 are substantially horizontally disposed relative to each other. Any number of rows and columns may be provided, depending upon the particular situation.

[0095] For example, and without limitation, the illustrated embodiment shows the housing 2 including a plurality of compartments 3 formed in at least two columns, and, a plurality of outlets 6 formed in at least one column which is positioned intermediate to said two columns of compartments 3.

[0096] The housing 2 and/or said door(s) 4 is/are formed substantially of any one or combination of electrically insulative material, UV stabilised material, and, a fire rated polymer such as polyethylene.

[0097] The housing 2 may include a mains power cable 13 adapted to supply mains power to said charging station 1. The housing 2 may include strategically positioned cleats 14 thereon, about which the power cord 13 may be wrapped so that it can be safely maintained in an appropriate position.

[0098] Additionally, or alternatively, the housing 2 may have a retraction mechanism associated therewith which is adapted to retract said mains power cable 13 within said housing 2. This can neatly contain any unrequired length of cable 13 whilst the charging station 1 is in use, and, also completely retract the cable 13 within the housing 2 when the charging station 1 is not in use or whilst it is being moved or relocated.

[0099] In another exemplary form, the housing tis adapted to be wall mounted via orifices 15 (see FIG. 6. This can be useful in certain situations, for example, when floor space is limited, when the housing is installed in a permanent or semi-permanent installation, or, when it is desired to securely retain the housing 2 to avoid movement of the charging station 1 in the event of a windy environment or the like.

[0100] It will be appreciated that the present invention therefore provides a housing in which a tradesperson's power tools may be placed whilst being charged which retains all tools in an orderly manner, which is secure to minimise the occurrence of theft which protects the tools and batteries placed there from adverse weather conditions or other environmental effects, and, which also prevents the unnecessary/unauthorised handling of a particular tradesperson's tools by another tradesperson to consequently minimising any spread of disease or the like between personnel.

[0101] Whilst the present invention has been hereinbefore described with reference to specific embodiments, it will be appreciated that numerous variations and modifications may be made thereto. All such variations and modification which become apparent to persons skilled in the art should be considered to fall within the spirit and scope of the present invention as hereinbefore described and as hereinafter claimed.
