Kinetic log splitter
View Patent ↗A kinetic log splitter having: a frame; a geared rack; a pinion coupled with the geared rack and to cause the geared rack to translate linearly based on rotation of the pinion; an actuation handle that engages the geared rack and the pinion; and a linkage system coupling the actuation handle to the geared rack that allows disengagement of at least a portion of the linkage system in response to a stall condition that occurs due to a stall of the geared rack during the operation of the geared rack of the kinetic log splitter. The kinetic log splitter may be towable and/or include a push plate splinter recovery system.
1. A kinetic log splitter comprising:
a frame;
a geared rack;
a pinion coupled with the geared rack and to cause the geared rack to translate linearly based on rotation of the pinion; a motor coupled to the pinion;
an actuation handle that engages the geared rack and the pinion, wherein the actuation handle comprises a first upper portion pivotally coupled to a second lower portion, and a spring that couples the first upper portion to the second lower portion, and wherein the spring is configured to release tension during kickback when the force overcomes the spring tension;
a linkage system coupling the actuation handle to the geared rack that allows disengagement of at least a portion of the linkage system in response to a stall condition that occurs due to a stall of the geared rack during the operation of the geared rack of the kinetic log splitter.
2. The kinetic log splitter of claim 1 , wherein the linkage comprises a mid-link and an over center linkage, wherein the mid-link couples the actuation handle to the over center linkage.
3. The kinetic log splitter of claim 2 , wherein the over center linkage comprises an engagement bearing.
4. The kinetic log splitter of claim 2 , wherein the over center linkage comprises a lobe that comes into contact with a fixed point of the frame of the kinetic log splitter, thereby limiting a movement of at least a portion of the over center linkage.
5. The kinetic log splitter of claim 1 , wherein the geared rack is free floating and rotation of the actuation handle engages the geared rack with teeth of the pinion.
6. The kinetic log splitter of claim 1 , further comprising a kinetic energy absorption component that reduces or absorbs kickback force from disengagement of the linkage system in response to a stall condition.
7. The kinetic log splitter of claim 1 , wherein the kinetic energy absorption component comprises a spring.
8. The kinetic log splitter of claim 7 , wherein the spring comprises one or more of a tension spring, a compression spring, or a torsion spring.
9. The kinetic log splitter of claim 1 , wherein the spring that couples the first upper portion of the handle and a second lower portion of the handle comprises a torsion spring.
10. The kinetic log splitter of claim 1 , wherein the mid-link comprises a release slot.
11. The kinetic log splitter of claim 1 , wherein the kinetic log splitter is towable.
12. The kinetic log splitter of claim 1 , wherein the kinetic log splitter further comprises a push plate splinter recovery system.
13. The kinetic log splitter of claim 11 , further comprising:
an extendable towing tongue, wherein the extendable towing tongue extends from the frame and is positionable between a towing configuration and a working configuration;
a collapsible stand, wherein the collapsible stand rotationally fixed to the frame and is positionable between a towing configuration and a working configuration;
a towing locator that locates extendable towing tongue and collapsible stand in the towing configuration; and
a pin that is configured to insert into the towing locator to lock the extendable towing tongue in the towing configuration.
14. The towable kinetic log splitter of claim 13 , further comprising:
a working locator that positions the collapsible stand in the working position.
15. The towable kinetic log splitter of claim 14 , wherein the pin is also configured to insert into the working locator to lock the extendable towing tongue in the working configuration.
16. The towable kinetic log splitter of claim 13 , wherein the towing locator is affixed to the extendable towing tongue, and wherein the collapsible stand rotates into position when the extendable towing tongue is in the extended position.
17. The towable kinetic log splitter of claim 13 , wherein the extendable towing tongue further comprises a stop that prevents the extendable towing tongue from being pulled from towable kinetic log splitter during towing.
18. The kinetic log splitter of claim 1 , where the push plate splinter recovery system, comprises:
a ram that travels down a beam of a kinetic log splitter, the ram further comprising a push plate and one or more guide flanges that guide the push plate down the beam; and
one or more rotatable asymmetric pins having a width smaller than a height and wherein rotation of one or more rotatable asymmetric pins releases pressure on the beam allowing for splinter removal.
19. The kinetic log splitter of claim 18 , wherein the one or more rotatable asymmetric pins are configured for rotation by a wrench or an inserted shaft.
20. The kinetic log splitter of claim 18 , wherein the one or more rotatable asymmetric pins are rotationally coupled to the one or more guide flanges.
