What is claimed is:
1. A broadhead having expanding blades, expanding upon striking and entering a target, including:
a) a longitudinally extending body having a forward, target penetrating end and a rearward end attachable to an arrow shaft;
b) a longitudinally extending passage through said body;
c) a pair of blade members having a forward end and a rear end, positioned in said body passage, each of said blades including:
1) a cutting surface directed outwardly of said body;
2) mass and weight reducing guiding means permitting longitudinal sliding movement within said passage;
d) blade holding means for retaining said blades within said body passage while permitting rearward movement thereof; and,
e) said guiding means and said blade holding means permitting longitudinal movement of said blades within said body passage while allowing said rear end of said blades to move radially outward of said body passage to a radially expanded position.
2. A broadhead having expanding blades as set forth in claim 1 and said forward end of said blades having a portion thereof arranged outwardly of said body, to abut with a target and moving said blades rearwardly as the broadhead penetrates a target.
3. The broadhead as set forth in claim 1 wherein said guiding means includes a slot formed in said blade.
4. The broadhead as set forth in claim 3 wherein said blade holding means is positioned within said body passage and within said blade slot.
5. The broadhead as set forth in claim 1 and said blades including a camming surface opposite said cutting surface and means for camming said rear ends of said blades outwardly, said blade being cammed outwardly from said body and said body passage as the same is moved rearwardly by contacting a target.
6. The broadhead as set forth in claim 5 and said camming means arranged in said body passage.
7. The broadhead as set forth in claim 5 and a notch provided in said camming surface, arranged to engage said camming means when said blades are in an inflight position.
8. The broadhead as set forth in claim 5 and means for retaining said blades in their inflight position.
9. The broadhead as set forth in claim 1 and means for holding said blades in their radially expanded position.
10. A broadhead having expanding blades, expanding upon striking and entering a target, including:
a) a longitudinally extending body having a forward, target penetrating end and a rearward end attachable to an arrow shaft;
b) at least one longitudinally extending groove formed in said body;
c) a blade, having a forward end and a rear end, positioned in said body groove, said blade including:
1) a cutting surface directed outwardly of said body,
2) mass reducing guiding means permitting longitudinal movement of said blade within said groove;
d) blade holding means for retaining said blade within said body groove while permitting rearward movement thereof, and,
e) said guiding means and said blade holding means permitting longitudinal movement of said blade within said body groove while allowing said rear end of said blade to move radially outward of said body groove to a radially expanded position.
11. A broadhead having expanding blades as set forth in claim 10 wherein;
a) said body is provided with at least a pair arcuately spaced grooves; and,
b) each of said grooves is provided with a blade.
12. A broadhead having expanding blades as set forth in claim 10 wherein;
a) said body is provided with a plurality of arcuately spaced grooves; and,
b) each of said grooves is provided with a blade.
13. A broadhead having expanding blades as set forth in claim 10 wherein said guiding means includes a slot formed in said blade.
14. A broadhead having expanding blades as set forth in claim 13 wherein said blade holding means is associated with said slot.
15. A broadhead having expanding blades as set forth in claim 13 and said blade slot being arcuately shaped to shift said rear end of said blade outwardly to an expanded, cutting position, as the same is shifted longitudinally within said slot.
16. A broadhead having expanding blades as set forth in claim 10 and means for holding said blades in a closed inflight position.
17. A broadhead having expanding blades as set forth in claim 10 and means for holding said blades in expanded position.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cambering vehicle for human propelled transport comprising:
an elongate front column having a longitudinal axis;
first and second pivot axles at said front column;
a first trailing arm pivotally attached to said first pivot axle;
a second trailing arm pivotally attached to said second pivot axle; and,
first and second rear wheels associated with said first and second trailing arms;
wherein said first and said second pivot axles are inclined from an imaginary line perpendicular to said longitudinal axis of said front column.
2. The cambering vehicle of claim 1, wherein said inclination is downward.
3. The cambering vehicle of claim 1, wherein said front column further comprises an internal steering stem with a front fork, said front fork having a front wheel rotatably engaged thereto, and wherein said internal steering stem may rotate within said front column turning said front wheel to steer said cambering vehicle.
4. The cambering vehicle of claim 3, further comprising a handle in communication with said steering stem, said handle adapted so as to selectively rotate said internal steering stem within said front column.
5. The cambering vehicle of claim 1, further comprising a braking mechanism for retarding rotation of one or both of said first and second rear wheels.
6. The cambering vehicle of claim 4, further comprising a braking system, said braking system comprising a hand-actuated lever mounted upon said handle, a braking mechanism adjacent said first rear wheel, and a cable connecting said braking mechanism to said hand-actuated lever, wherein actuation of said hand-actuated lever pulls said cable forcing said braking mechanism against said first wheel with sufficient friction to retard rotation of said first rear wheel.
7. The cambering vehicle of claim 1, further comprising a crossbar linking said first trailing arm to said second trailing arm.
8. The cambering vehicle of claim 7, wherein said crossbar comprises a first end pivotally secured to one of said first and said second trailing arms with a first pin.
9. The cambering vehicle of claim 8, wherein said first pin is selectively removable.
10. The cambering vehicle of claim 9, further comprising a cover assembly engaged with said crossbar and adapted to protect said first pin from being decoupled from said crossbar when in a first position.
11. The cambering vehicle of claim 10, wherein said cover assembly is rotatably engaged to said crossbar.
