Definitions

• This invention relates to portable tool boxes and more particularly to a portable tool box for a compressed air tool dispensing gun such as an adhesive gun, nail gun, mixer gun, sausage gun, ratio-pack gun and the like.
• a compressed air tool dispensing gun such as an adhesive gun, nail gun, mixer gun, sausage gun, ratio-pack gun and the like.
• the invention will be described in relation to a portable air-powered adhesive gun but it is to be understood that the invention extends to both other forms of dispensing gun as well as other air powered tools.
• Adhesive guns may be either air-powered or manually actuated.
• Air- powered adhesive guns generally require an air compressor and an air reservoir for operation and hitherto those compressors have been very heavy, very bulky and generally difficult to move about a work site. It is these disadvantages of air-powered adhesive guns that leads to the use of manually actuated adhesive dispensing guns on building sites in circumstances where an air-powered adhesive gun would lead to greater productivity and less worker fatigue and worker injuries.
• a portable tool box comprising a container having a lid, within which container is mounted an electrically operated air compressor.
• the container has walls, and a vent mounted in one of the walls.
• the compressor is electrically connected to a connection box which is electrically accessible from an exterior of the container.
• the container further comprises one or more general purpose electrical outlets which are electrically connected to the connection box.
• the tool box further contains a pneumatic hose and a tool which connects to the compressor with the hose.
• the container has formed therein an opening through which a hose may pass while the hose is connected to the compressor.
• the compressor is adapted to operate a dispensing gun without the need for an air reservoir or accumulator.
• the compressor is a medical grade - free compressor.
• the invention also provides a method of dispensing comprising the steps of:-
• the continuously operating air compressor does not require an air reservoir or accumulator.
• a portable air-powered tool comprising a container having an opening and closed by a lid, an electrically driven air compressor mounted within the container, at least one air vent in the walls of the container to permit air flow from the exterior to the interior of the container, electrical circuitry means within the container electrically connected to the air compressor and adapted to be connected to a power supply, said container being adapted to house an air-powered gun and an air line for connecting the gun to the air compressor.
• the electrical circuitry is connected to a general purpose power outlet adapted to receive an electrical lead for electrical devices such as lights, vacuum cleaners and power tools.
• the electrical circuitry may include a switch which enables the compressor to be switched off with the other device remaining on.
• the electrical circuitry may be connected to a battery pack within or external of the container or may be adapted for connection to a main supply.
• locking means for locking the lid to the container.
• the container may be provided with wheels, multiple handles and/or a pull-out handle.
• Fig. 1 is a perspective view of a potable tool box according to the teachings of the present invention
• Fig. 2 is a side elevation of the device depicted in Fig. 1
• Fig. 3 is another side elevation of the device depicted in Fig. 1
• Fig. 4 is an end elevation of the device depicted in Figs. 1 to 3;
• Fig. 5 is another end view of the device depicted in Figs. 1 to 4;
• Fig. 6 is an isometric perspective of the device of the present invention with the lid open;
• Fig. 7 is a front view of the device being carried;
• Fig. 8 is a side view of the device being pulled on its wheels, and
• Fig. 9 depicts in perspective view a person utilising the device of the present invention with the case closed.
• the tool box 10 shown in the drawings includes a container 11 having a lid 12 and locking means 13.
• the container 11 has a base 14 with optional skids 14a, end walls 15 and 16 and side wall 17 and 18.
• An electrically operated air compressor 19 is mounted within the container 11 on or near the base 14.
• Air vents 20 and 21 are provided in the end walls 15 and 16.
• the container is preferably formed from high impact polymer in a clamshell design with a hinge 70 along a bottom edge.
• An electrical circuit within the container 11 includes a connection box 22 adapted to be connected from a fixture 22a to a main supply by an extension lead.
• a line leads from the box 22 to the electrical terminals of the compressor 19 through an on/off switch 25.
• Line 26 connects one or more general purpose outlets 27 to the connection box 22.
• the purpose of the switch 25 is to enable power to be supplied to the general purpose outlets 27 when the compressor 19 is turned off. For example, a light could be connected to one of the general purpose outlets 27 and it can be therefore used without having to run the compressor at the same time.
• the circuitry may also incorporate a miniature circuit breaker and a residual current device.
• An adhesive gun 28 is positioned within the container 11 for example with clips 51 along with an air hose line 29 which is used to couple the gun 28 to the compressor 19.
• the compressor 19 is a light weight compressor having a long term continuous operating capacity which enables the use of a much smaller and lighter compressor than currently used compressors which may have a substantial accumulator vessel that is charged by the intermittent running of the compressor.
• the compressor is a medical grade oil- free compressor.
• the compressor may be moderated by a blow-off valve with silencer which maintains an optimum pressure level and prevents pressure back-up during re-starts and motor overload. It is anticipated that the complete portable operated tool of the invention would weigh in the vicinity of 5kg as opposed to 25 to 30kg or much more for current equipment.
• the container 11 has a handle 30 but various combination of handles could be provided on the lid 12, the side walls and the end walls 15 and 16 of the container 11.
• a pull-out handle 40 could also be used in which case the container 11 would be fitted with wheels 41 as shown in Fig. 8.
• an opening 50 is provided in a wall to allow the hose 19 to exit the container when the hose is connected to the compressor 19.
• the compressor 19 could be coupled to one or more air vents by a housing to ensure that items placed in the container 11 do not block the flow of air to the compressor 19.
• Releasable fastener means may be provided to secure the adhesive gun 28 and the hose line 29.
