Abstract

The present invention is a multi-purpose utility cutter apparatus having two body members rotatably connected at a pivot point to form two jaw portions and two handles, with at least one of the jaw portions formed with a blade holding mechanism.

First claim

The invention claimed is:

1. A blade clamping mechanism comprising:
a blade holder comprising a blade channel formed with a clamping plate receiving hole and adapted to receive a blade;
a screw member comprising a knob portion and a shaft portion, the shaft portion comprising a stopper member and a threaded portion; and
a clamping plate having an opening adapted to receive and travel along a portion of the shaft portion, the clamping plate adapted to travel through the clamping plate receiving hole.

2. The blade clamping mechanism of claim 1 , wherein the stopper member is between the threaded portion and the knob portion.

3. The blade clamping mechanism of claim 1 , wherein an inner face of the clamping plate is configured to selectively abut a portion of the blade in the blade holder to retain the blade between the clamping plate inner face and an interior portion of the blade channel.

4. The blade clamping mechanism of claim 1 , wherein the position of the stopper member is adjustable relative to the blade channel, making the stopper member moveable to at least a first stopper position wherein the stopper member presses against the clamping plate to secure the blade within the blade channel.

5. The blade clamping mechanism of claim 1 , wherein rotation of the screw member directs the stopper member towards the clamping plate and the clamping plate towards an opposing interior sidewall of the blade channel to clamp the blade.

6. A blade holding mechanism comprising:
a blade holder comprising a first channel member opposing a second channel member to form a blade channel adapted to receive a blade, at least one of the channel members formed with a clamping mechanism receiving hole; and
a clamping mechanism comprising:
a screw member comprising a knob portion and a shaft portion, the shaft portion comprising a stopper member and a threaded portion, the shaft portion adapted to travel through the clamping mechanism receiving hole; and
a clamping plate disposed between the stopper member and the threaded portion and having a shaft portion opening configured to receive and travel along a portion of the shaft portion.

7. The blade holding mechanism of claim 6 , wherein the threaded portion of the shaft portion is adapted to threadably engage with a screw member receiving hole in the second channel member.

8. The blade holding mechanism of claim 7 , wherein rotation of the screw member and engagement of the threaded portion and the screw member receiving hole of the second channel member directs the stopper member of the shaft portion towards the second channel member, thereby directing the clamping plate towards the second channel member to clamp the blade disposed in the blade holder.

9. The blade holding mechanism of claim 7 , wherein a screw platform implement is disposed on the first channel member and a portion of the screw platform implement is disposed between the knob portion and the stopper member of the screw member, the screw platform implement configured to prevent the threaded portion of the screw member from unthreading from the screw member receiving hole.

10. The blade holding mechanism of claim 6 , wherein rotation of the screw member directs the stopper member of the shaft portion directs towards the clamping plate, to move the clamping plate through a receiving hole in the first channel member and towards the second channel member, to abut and secure the blade within the blade channel.

11. The blade holding mechanism of claim 6 , wherein compression of the clamping plate against a portion of the blade prevents dislodgement of the blade from within the blade channel.

12. The blade holding mechanism of claim 6 , wherein the clamping plate is of a thickness to maintain contact with an internal portion of a clamping plate receiving hole of the first channel member while the clamping plate clamps the blade disposed in the blade channel.

13. The blade holding mechanism of claim 6 , wherein an internal sidewall of the blade channel comprises one or more protruding elements adapted to mate with one or more indents formed on a spine side of the blade.

14. The blade holding mechanism of claim 6 , wherein the shaft portion comprises a first shaft section with a first diameter and a second shaft section with a second diameter which is smaller than the first diameter, and the stopper member is disposed on the first shaft section and the clamping plate is disposed on the second shaft section.

15. A multi-purpose tool comprising:
a pair of body members rotatably connected at a pivot point to form a pair of jaw portions and a pair of handles, with at least one of the jaw portions formed with a blade holding mechanism comprising:
a blade holder comprising a first channel member opposing a second channel member to form a blade channel adapted to receive a blade, each channel member formed with one or more receiving holes;
a screw member comprising a knob portion and a shaft portion, the shaft portion comprising a stopper member and a threaded portion; and
a clamping plate having a shaft portion opening configured to receive and travel along a portion of the shaft portion.

16. The multi-purpose tool of claim 15 , wherein the clamping plate is movably disposed on the screw member between the stopper member and the threaded portion of the shaft portion.

17. The multi-purpose tool of claim 15 , wherein the shaft portion stopper member directs movement of the clamping plate through a clamping plate receiving hole of the first channel member and towards an internal sidewall of the second channel member.

18. The multi-purpose tool of claim 15 , wherein rotation of the screw member directs the stopper member towards the clamping plate to move the clamping plate to compress a portion of the blade disposed in the blade channel to secure the blade within the blade channel.

19. The multi-purpose tool of claim 15 , wherein the clamping plate is of a thickness to maintain contact with an internal portion of a clamping plate receiving hole of the first channel member ssss while the clamping plate clamps the blade disposed in the blade channel.

20. The multi-purpose tool of claim 15 , wherein at least one handle of the pair is formed with a blade drawer opening adapted to receive a blade drawer configured to store one or more blades.
