Bulb planter with twin grips
View Patent ↗A bulb planter includes a pair of blade halves cooperating to form a tubular tool head and a molded plastic handle body forming a pair of handles. The blade halves are preferably metal and riveted to the handle body. The handle body forms a living hinge for selectively pivoting the blade halves upon movement of the handles. The blade halves pivot toward and away from each other between a soil plug cutting position and a soil plug releasing position upon movement of the handles. A resilient member biases the blade halves toward the soil plug cutting position. The resilient member is preferably an elastomer ring encircling the blade halves. The handles extend in opposed directions substantially perpendicular to a central longitudinal axis and are manually movable against the bias of the resilient member to move the blade halves to the soil plug release position.
1. A bulb planter comprising, in combination:
a pair of blade halves cooperating to form a tubular tool head having a central longitudinal axis;
a pair of handles operably connected to the blade halves to selectively move the blade halves; and
wherein the blade halves are operatively hinged so that the blade halves pivot toward and away from each other upon movement of the handles between a soil plug cutting position wherein side edges of the blade halves are together to form the tubular tool head and lower ends of the blade halves form a substantially circular lower cutting edge so that a soil plug can be cut by the tool head and a soil plug releasing position wherein the side edges of the blade halves are separated and the lower ends of the blade halves are moved outward away from one another relative to the soil plug cutting position so that the soil plug falls out of the tool head.
2. The bulb planter according to claim 1 , wherein the handles extend in opposed directions substantially perpendicular to the central longitudinal axis.
3. The bulb planter according to claim 2 , wherein the handles are each cantilevered outward in a direction away from the central longitudinal axis.
4. The bulb planter according to claim 2 , wherein the handles move inwardly toward each other to move the blade halves to the soil plug release position.
5. The bulb planter according to claim 1 , wherein the handles are each formed by a molded plastic handle body and the blade halves are each secured to a respective body.
6. The bulb planter according to claim 5 , wherein the blade halves comprise metal and have a serrated lower cutting edge.
7. The bulb planter according to claim 5 , wherein the blade halves comprise metal and are riveted to the handle body.
8. The bulb planter according to claim 5 , wherein the handle body forms a living hinge for pivoting the blade halves.
9. The bulb planter according to claim 1 , further comprising a resilient member biasing the blade halves inwardly from the soil plug releasing position toward the soil plug cutting position.
10. The bulb planter according to claim 9 , wherein the resilient member comprises an elastomer ring encircling the blade halves coaxial with the central longitudinal axis.
11. The bulb planter according to claim 1 , wherein the blade halves pivot about a living hinge.
12. The bulb planter according to claim 1 , wherein the side edges of the blade halves overlap when in the soil plug cutting position.
13. A bulb planter comprising, in combination:
a tubular cutting head having a central longitudinal axis;
a pair of handles connected to the cutting head;
wherein the handles extend in opposed directions substantially perpendicular to the central longitudinal axis; and
wherein the tubular cutting head includes a pair of blade halves operatively hinged so that the blade halves pivot toward and away from each other upon movement of the handles between a soil plug cutting position wherein side edges of the blade halves are together to form the tubular cutting head and lower ends of the blade halves form a substantially circular lower cutting edge so that a soil plug can be cut by the cutting head and a soil plug releasing position wherein the side edges of the blade halves are separated and the lower ends of the blade halves are moved outward away from one another relative to the soil plug cutting position so that the soil plug falls out of the tubular cutting head.
14. The bulb planter according to claim 13 , wherein the handles are each cantilevered outward in a direction away from the central longitudinal axis.
15. The bulb planter according to claim 13 , wherein the handles are formed by a molded plastic handle body and the cutting head is secured to the body.
16. The bulb planter according to claim 15 , wherein the cutting head comprises metal and has a serrated lower cutting edge.
17. The bulb planter according to claim 15 , wherein the cutting head comprises metal and is riveted to the handle body.
18. The bulb planter according to claim 13 , wherein a resilient member biases the blade halves inwardly from the soil plug releasing position toward the soil plug cutting position.
19. The bulb planter according to claim 18 , wherein the resilient member comprises an elastomer ring encircling the blade halves coaxial with the central longitudinal axis.
20. The bulb planter according to claim 13 , wherein the side edges of the blade halves overlap when in the soil plug cutting position.
21. A bulb planter comprising, in combination:
a pair of blade halves cooperating to form a tubular tool head having a central longitudinal axis;
a molded plastic handle body forming a pair of handles;
wherein the blade halves are secured to the handle body;
wherein the handle body forms a living hinge for selectively pivoting the blade halves upon movement of the handles;
wherein the blade halves pivot toward and away from each other upon movement of the handles between a soil plug cutting position wherein side edges of the blade halves are together to form the tubular tool head and lower ends of the blade halves form a substantially circular lower cutting edge so that a soil plug can be cut by the tool head and a soil plug releasing position wherein the side edges of the blade halves are separated and the lower ends of the blade halves are moved outward away from one another relative to the soil plug cutting position so that the soil plug falls out of the tool head;
a resilient member biasing the blade halves inwardly from the soil plug releasing position toward the soil plug cutting position; and
wherein the handles extend in opposed directions substantially perpendicular to the central longitudinal axis and are manually movable against the bias of the resilient member to move the blade halves to the soil plug release position.
22. The bulb planter according to claim 21 , wherein the resilient member comprises an elastomer ring encircling the blade halves coaxial with the central longitudinal axis.
23. The bulb planter according to claim 21 , wherein the side edges of the blade halves overlap when in the soil plug cutting position.
