Interaction between a key duplication housing and a key blank carrier
View Patent ↗A key duplication system may include a housing, a key blank receiving aperture, a cutter and a clamp adjacent to the receiving aperture, wherein the key blank is guided to a predetermined position in relation to the cutter through engagement of a carrier with the housing. A method of aligning a key blank blade with a key blank carrier in relation to a cutter may include guiding a key blade into a cutting position through contact with a key blade receiving aperture, securing at least a portion of the carrier with a clamp, cutting a key bit pattern into the key blank blade and releasing the key blank.
1. A key duplication system comprising:
a key duplication system housing;
at least one key blank receiving aperture sized to receive at least a key blank blade wherein the at least one key blank receiving aperture is located on a surface of a first side of the key duplication system housing;
at least one cutter within the housing adjacent to the at least one key blank receiving aperture; and
at least one key blank carrier clamp adjacent to the at least one key blank receiving aperture, the at least one key blank carrier clamp positionable to securely contact an outer surface of a key blank carrier;
wherein the key blank blade is guided to a predetermined position in relation to the at least one cutter through mechanical engagement of the outer surface of the key blank carrier and at least a portion of the key blank receiving aperture;
wherein the key blank carrier clamp is positionable to clamp the key blank carrier in a cutting position in relation to the at least one cutter; and
wherein the key blank blade is in the predetermined position when the key blank carrier is in the cutting position.
2. The key duplication system of claim 1 , wherein the at least one key blank receiving aperture comprises a perimeter shape configured to match a corresponding shape of the cross sectional outer surface of the key blank carrier.
3. The key duplication system of claim 2 , wherein the perimeter shape comprises at least one of a ridge or groove configured to match a corresponding groove or ridge on the outer surface of the key blank carrier.
4. The key duplication system of claim 1 , wherein the at least one key blank receiving aperture comprises a plurality of angled surfaces adjacent to the at least one key blank receiving aperture, the plurality of angled surfaces each angling away from the at least one key blank receiving aperture to form a tapered entry port between a user and the at least one key receiving aperture.
5. The key duplication system of claim 1 , wherein the at least one key blank receiving aperture is configured to receive the key blank carrier into the at least one key blank receiving aperture either in an orientation in which a tip end of the key blank carrier is inserted first or in an orientation in which a bit edge of the key blank is inserted first.
6. The key duplication system of claim 1 , further comprising a digital reader coupled to the housing and angled toward the at least one key blank receiving aperture, the digital reader positioned to read an identification code affixed on an outer surface of the key blank carrier when the key blank blade is received by the at least one key blank receiving aperture.
7. The key duplication system of claim 1 , further comprising a light adjacent to the at least one key receiving aperture and oriented to pass a beam of light through an opening placed on the key blank carrier when the key blank carrier is positioned at a fully inserted position into the at least one key blank receiving aperture.
8. The key duplication system of claim 1 , further comprising at least one movable guard adjacent to the at least one key blank receiving aperture, the at least one movable guard movable to block at least a portion of the at least one key blank receiving aperture.
9. The key duplication system of claim 1 , further comprising a pressure sensor coupled to the housing and positioned for activation by the key blank when the key blank carrier is positioned at a fully inserted position into the at least one key blank receiving aperture.
10. The key duplication system of claim 1 , wherein the at least one key blank receiving aperture further comprises a pivotal support, wherein at least a portion of the at least one key blank receiving aperture is configured to be pivotable around an axis corresponding to the center axis of at least one of the key blank blade or the key blank carrier.
11. The key duplication system of claim 1 , wherein the at least one key blank carrier clamp is further positioned to engage a portion of the outer surface of the key blank carrier extending from the key blank head.
12. The key duplication system of claim 11 , wherein the at least one key blank carrier clamp is further positioned to engage a portion of the key blank carrier in direct contact with the key blank blade.
13. The key duplication system of claim 1 , where the at least one cutter comprises a constant speed motor driving a cutting wheel.
