LOG SPLITTER WITH TWO HANDED OPERATION FEATURES
Embodiments herein provide systems, devices, and methods for splitting logs, wood, and other materials. A splitting device safety feature is disclosed, the safety feature comprising a safety locking mechanism that generally requires operation or activation by at least one hand of a user and an activation mechanism which generally requires activation or use with the other hand of a user. Both mechanisms are required to be activated, each by at least one hand of a user, in a simultaneous manner in order to activate at least some features. For example, a safety lock out mechanism is provided that prevents or blocks the activation of the device from initiating log splitting processes. Therefore, two distinct features requiring the use of at least one hand of a user are required to be activated or operated in order to perform log splitting functions.
1 . A log splitter comprising:
a safety release member operable by a first hand of a user; and
a splitter activation member operable by a second hand of the user,
wherein operation of both the safety release member and the splitter activation member are required to enable performance of log splitting operation of the log splitter.
2 . The log splitter of claim 1 , wherein the safety release member and the splitter activation member each comprise a user actuable element, the user actuable elements separated from each other a distance sufficient to prevent one-handed operation of both the safety release member and the splitter activation member.
3 . The log splitter of claim 2 , wherein the distance is at least about 12 inches.
4 . The log splitter of claim 2 , further comprising a housing containing one or more features of the log splitter, and wherein the user actuable elements of the safety release member and the splitter activation member are accessible from outside the housing.
5 . The log splitter of claim 4 , further comprising an aperture present on an exterior of the housing, wherein the safety release member is recessed at least partially within the aperture.
6 . The log splitter of claim 1 , wherein at least one of the safety release member and the splitter activation member is located distal from a location where the log splitting operation occurs.
7 . The log splitter of claim 1 , wherein the safety release member is part of a safety lock out mechanism, the safety lock out mechanism comprising:
a lock member, and
a lock out shaft coupled at a first end to the lock member and at a second end to the safety release member.
8 . The log splitter of claim 7 , wherein the lock member prevents actuation of the splitter activation member when the safety release member is in a non-actuated position.
9 . The log splitter of claim 7 , wherein actuation of the safety release member causes the lock member to move and permit actuation of the splitter activation member.
10 . The log splitter of claim 7 , wherein the lock member is angularly rotatable between a first position in which actuation of the splitter activation member is prevented and a second position in which actuation of the splitter activation member is permitted.
11 . The log splitter of claim 10 , wherein the lock member is biased in the first position by a biasing member.
12 . The log splitter of claim 1 , wherein the splitter activation member comprises a drive release member configured to trigger performance of the log splitting operation when the drive release member is actuated.
13 . The log splitter of claim 12 , further comprising a biasing member biasing the drive release member in a non-actuated position.
14 . The log splitter of claim 13 , wherein actuation of the drive release member requires use of force sufficient to overcome a biasing force provided by the biasing member.
15 . A log splitter comprising:
a first shaft having a safety release member, the first shaft hingedly connected to a lock member, the lock member and the hingedly connected first shaft biased toward a first position;
a second shaft hingedly connected to a lever and oriented substantially perpendicular to the first shaft and biased in an upward direction;
the lock member preventing downward displacement of the second shaft and the lever when the first shaft and the lock member are disposed in the first position; and
wherein actuation of log splitting operation is achieved by downward displacement of the second shaft.
16 . The log splitter of claim 15 , wherein contact between the safety release member and the lever is necessary to permit downward displacement of the second shaft and actuation of the log splitting operation.
17 . A method of splitting logs, comprising:
providing a log splitter comprising a log-supporting track having a first end and a second end;
the first end of the track having a splitting wedge;
the second end of the track having an anvil mounted to reciprocate along the track;
the anvil fixedly attached to a rack member;
the rack member in selective force-transmitting communication with a fly-wheel;
the fly-wheel adapted to be driven by an engine;
a first shaft having a safety release member, the first shaft hingedly connected to a lock member, the lock member and the hingedly connected first shaft biased toward a first position;
a second shaft hingedly connected to a lever and oriented substantially perpendicular to the first shaft and biased in an upward direction;
the lock member preventing downward displacement of the second shaft and the lever when the first shaft and the lock member are disposed in the first position;
wherein a force-transmitting communication between the rack member and the fly-wheel is achieved by downward displacement of the second shaft;
loading a material to be split between the anvil and the splitting wedge;
applying a force to the safety release member to displace the safety release member and the first shaft from a first position to a second position; and
applying a second force to the lever to place the rack member and the fly-wheel in force-transmitting communication and displace the anvil from a first position to a second position.
