Abstract
The invention is directed to an adhesive tape dispenser adapted for use with adhesive tape having a releasable backing such as wax paper, foil or vinyl often used in HVAC applications. The adhesive tape dispenser includes a handgrip for holding the tape dispenser in one hand during use, a finger switch provided on the handgrip and activated to operate a motorized gearing system for automatically removing and storing the releasable backing simultaneously while applying the adhesive tape to a surface, and a light source for illuminating dark or low lit surface areas.
Claims10
A adhesive tape dispenser adapted to dispense adhesive tape stored on a spool and and having a backing substrate, said adhesive tape dispenser comprising:
- a frame including a cavity in which said spool of adhesive tape is rotatably mounted therein, and a handgrip extending downwards from said frame and including a removable end cap;
- an application guide attached at a distal end of said frame;
- a pair of rollers mounted at said distal end of said frame, said adhesive tape disposed between said pair of rollers when extracted from said dispenser;
- a spool fastener removably fastened to accommodate replacement of said spool of adhesive tape;
- a collection chamber formed within said frame and adapted to store said backing substrate as said backing substrate is removed from said adhesive tape and wound into a coil;
- a removable closure closing said collection chamber to prevent said coil from exiting said collection chamber;
- a driver gear, a planetary gear, and a take-up gear aligned to rotate within said collection chamber, said gears interconnected with each other to rotate;
- an electrical motor mechanically coupled to said driver gear;
- a power source secured within said handgrip by said end cap;
- and
- an electrical switch disposed within said handgrip and protruding out from a switch opening formed within said handgrip so that users may operate said electrical switch with a finger when holding said handgrip in one hand, said electrical switch selectively operated to electrically couple said power source to said motor to rotate said driver gear so that said take-up gear winds said backing substrate within said collection chamber to form said coil.
A releasable sheet tape dispenser comprising:
- a handheld housing including a pistol grip and top opening having a disengagable fastener to accommodate replacement of a roll of adhesive tape including a releasable sheet, said housing having a distal opening to receive said releasable sheet;
- a pair of rollers aligned vertically one top of each other to rotatably engage said adhesive tape;
- a cavity formed within the housing and adapted to receive and store said releasable sheet as said releasable sheet is removed from said adhesive tape and wound within said cavity to form a roll of releasable sheet, said cavity including a removable closure to prevent said roll from exiting said cavity;
- interconnecting gears enclosed within said housing and releasably attached to said releasable sheet;
- an electric motor coupled to said interconnecting gears;
- a power source;
- an electrical switch situated about said pistol grip and selectively connecting said power source to said electric motor to wind said releasable sheet within said cavity simultaneously as said adhesive tape is extracted through said pair of rollers;
- and
- an interchangeable guide attached to said distal end of said housing.
