Abstract

A hand-held tape dispenser has a tape support hub and a support frame. A brake assembly is pivotally mounted on the frame, and has a curved brake actuator and flat brake plate. The brake plate is aligned to engage a tape roll mounted on the tape support hub and inhibit its free rotation (and dispensing) according to an operator'"'"'s selection of applied pressure. The brake plate bends about the tape roll as pressure is increased to facilitate tape cutting or tape stretching (in the case of stretchable tape in the dispenser).

Claims

1. A hand-held tape dispensing apparatus comprising:

a frame including a hub for rotatably supporting a roll of tape; and

a brake assembly having a brake actuator extending around a portion of the roll of tape, the brake actuator having a first end supported relative to the frame so that a second end thereof is movable towards and away from the roll of tape, and a brake plate disposed between the brake actuator and the roll of tape for frictional engagement with an outermost wrap of the roll of tape upon movement of the second end of the brake actuator toward the roll of tape.

2. The apparatus of claim 1 wherein the hub and brake actuator are formed to define a handle for the tape dispensing apparatus.

3. The apparatus of claim 1 wherein the brake plate has first and second ends, and wherein the brake plate is pivotally supported adjacent its first end relative to the roll of tape and brake actuator for movement therebetween.

4. The apparatus of claim 3 wherein the first end of the brake plate is pivotally supported adjacent the first end of the brake actuator.

5. The apparatus of claim 1 wherein the brake assembly has two operative positions,

a first position wherein the brake actuator is spaced from the roll of tape and the brake plate is generally planer and has a first area of contact between the roll of tape and the brake plate, and

a second position wherein the brake actuator is urged closer to the roll of tape and at least a portion of the brake plate is bent about the roll of tape and has a second, increased area of contact between the roll of tape and the brake plate.

6. The apparatus of claim 1 wherein the tape has adhesive disposed on at least a portion of at least one side thereof.

7. The apparatus of claim 1 wherein the tape is stretchable and has a leading end portion secured to a workpiece, and wherein the second end of the brake actuator is movable to a position adjacent the roll of tape whereby the brake plate prevents rotation of the roll of tape relative to the frame so that movement of the apparatus away from the workpiece stretches the tape therebetween.

8. The apparatus of claim 1 wherein the brake actuator is pivotally supported on the frame.

9. The apparatus of claim 8 and further comprising pivot stops to limit the extent of pivoting of the brake actuator relative to the frame.

10. The apparatus of claim 1 wherein the hub is separable from the frame.

11. A hand-held tape dispensing apparatus comprising:

a frame including a hub for rotatably supporting a roll of tape; and

a brake assembly which includes

a brake actuator disposed about a portion of the roll of tape, the brake actuator having a first end pivotally supported on the frame and having a second free end, and

a flexible brake plate aligned between the brake actuator and the roll of tape so that movement of the second end of the brake actuator towards the roll of tape urges the brake plate against the roll of tape as a brake to limit rotation of the roll of tape relative to the frame.

12. The apparatus of claim 11 wherein the brake assembly has two operative positions,

a first position wherein the brake actuator is spaced from the roll of tape and the brake plate is generally planar and has a first area of contact between the roll of tape and the brake plate, and

a second position wherein the brake actuator is urged closer to the roll of tape and at least a portion of the brake plate is bent about the roll of tape and has a second, increased area of contact between the roll of tape and the brake plate.

13. The apparatus of claim 11 wherein the brake plate contacts the roll of tape at approximately the midpoint of the brake plate.

14. The apparatus of claim 11 wherein the brake plate is supported adjacent its ends by the brake actuator, and wherein the brake actuator is arcuate at least between those portions thereof supporting the ends of the brake plate.

15. The apparatus of claim 11 wherein the frame has a tape applicator surface spaced from the hub and roll of tape thereon for engaging the tape as it is dispensed.

16. The apparatus of claim 11 wherein the hub and brake actuator are configured to be manually gripped by an operator.

17. The apparatus of claim 11 wherein the tape has adhesive disposed on at least a portion of at least one side thereof.

18. The apparatus of claim 11 and further comprising pivot stops to limit the extent of pivoting of the brake actuator relative to the frame.

19. The apparatus of claim 11 wherein the hub is separable from the frame.

20. The apparatus of claim 19 wherein the frame and hub have opposed tracks and rails for aligning and supporting the hub relative to the frame.

21. The apparatus of claim 11 wherein the brake plate has first and second ends, with its first end supported by the brake actuator, adjacent the first pivotally supported end of the brake actuator.
