Definitions
- the present invention relates generally to the field of implements for tending to a fire, more particularly, to manipulate logs and similar type objects in a fire.
- the present invention is a handling device having a rigid rod inserted through a cavity of a hollow tube, whereby the rod and tube operate independently, a griping end for cradling logs and a handle for manipulating the rod.
- the present invention is configured in such a way as to allow for gripping, cradling, and manipulation of logs with a minimal amount of energy.
- a device comprising a rigid rod, grasping end and gripping end would use the mechanism in the gripping end, typically a trigger type of mechanism to control the grasping end.
- the gripping end required a relatively large force to maintain a grasp on the log, making it difficult for certain classes of individuals to maintain a grasp on the log, or for those who could maintain a grasp to work the device infrequently due to local muscle fatigue, or to manipulate the log with difficulty and in an awkward manner.
- the user would position himself whereby the log and device were perpendicular to each other.
- the user would then operate a trigger type mechanism on the gripping end that would open and close a grasping mechanism around the circumference of a log. Then the user would manipulate the device to move the log into the position that was desired.
- the user When the desired position was reached, the user would release his grip on the gripping end, which in turn would be forced open at the grasping end by the weight of the log.
- the process required strength and coordination to position a log into place.
- the log would have to be balanced within the grasping end.
- U.S. Pat. No. 1,820,463 to Klein, issued on Aug. 25, 1931, teaches the ability to use a mechanical device to pick up and manipulate hot coals and the like.
- the gripping end is mechanically manipulated by squeezing together the mechanical device of the gripping end with the hand. This manipulation of the gripping end translates to movement in the grasping end. As the gripping end is squeezed, the grasping end closes around the desired object to be manipulated, thereby creating a tight grip around the object to be manipulated.
- an apparent disadvantage of the '463 patent is that the object that is being manipulated must be relatively small, as the strength of the hands and arms determines the limit of what can be manipulated. This severely limits the device's capabilities. Furthermore, the '463 patent would have difficulties in manipulating any type of object that is long in one dimension while relatively short in the other two dimensions, such as a log.
- the user of the '463 patent would have to grasp a long object from an angle perpendicular to the long dimension at a point that would balance the object in the grasping end. Then the user of the device would have used predominately arm strength to manipulate the object into the desired position. For heavy objects, not only would arm strength be required, but also the user would have to apply a required amount of hand strength to the grasping end for the object picked up to remain in the grasp of the grasping end. The amount of strength would depend on the mechanical advantage of the device.
- the present invention overcomes these limitations. First of all, long objects are picked in a parallel relationship. That is, the length of the device is parallel to the length of the object being manipulated. Therefore, the user can use leg strength to manipulate the position of the object.
- the object can be cradled or grasped in the grasping end and carried or dragged backwards.
- the log can be dragged right or left around the fire.
- the manipulation of the log would have minimal effect.
- the present invention does not need, but may, balance the manipulated object by lifting it completely off the ground.
- the present invention does not require squeezing to grasp an object.
- a torsional action which requires much less strength, may be used to cradle the manipulated object.
- the present invention allows for strength to be used for different movement. That is, one hand can manipulate the torsional action to control the grasp of a log, while the other hand manipulates the other axises—right, left, up and down. Also, depending on how far one grasps the rod, one can lift a much greater amount on the grasping end.
- the angle of the gripping end allows for the grasping end to naturally close due to gravity.
- the curvature of the claws allows the log to sit in place, as if being cradled, with minimal amount of torsional force. Most of the torsional force will be to hold the claws together and is minimally affected by the weight of the object being manipulated.
- U.S. Pat. No. 2,429,046 to Billig issued on Oct. 14, 1947, discloses a device for dual action as a poker and as a tong.
- As a tong there is a gripping end, shank and jaw.
- the opening of the jaw is manipulated by secondary grip that slides longitudinally along the shank. This secondary grip allows the user to manipulate heavier objects through the use of two hands.
- the position of the secondary handle is determined by how far open the jaws must be to grasp the manipulated object.
- the grip and secondary grips will be in closer proximity than when the manipulated object is smaller, and presumably lighter; thereby, losing the advantage of two hand manipulation for larger, heavier objects.
- the present invention overcomes these limitations by, for example, having a torsional action for cradling or grasping the manipulated object as opposed to requiring opposing forces to grasp the manipulated object, thereby allowing greater amount of strength for manipulating the object than the '046 patent.
- the present invention equivalent to a secondary grip is fixed in a non-movable predetermined position that has been determined to provide the best leverage for manipulating objects for the size of objects the device was designed to manipulate.
- the present invention is positioned parallel to the longitudinal length of the manipulated object, where the '046 patent would be positioned perpendicular to the manipulated object.
- the sideloader comprises a jaw, an arm and a lever.
- the length of the log will determine how large the jaw is opened.
- the jaw is manually adjusted until the jaw opening is slightly larger than the log.
- the lever is mechanically attached to the jaws, such that when the lever is operated the jaws will close, forming a friction fit on the log. Then the log may be manipulated.
- the side loader is designed such that the user operates the sideloader from the side.
- the sideloader jaw must frictionally engage both ends of the log longitudinally.
- the length of the arm would determine the length of the log to be manipulated.
- the length of the log manipulated would be relatively short. Because of the cantilever method of lifting the log, as the longer the log is that is to be manipulated, the quicker it becomes difficult to manipulate ever-increasing log lengths.
- the present invention is designed such that the user may operate the invention from where the log is cradled or grasped.
- a user may cradle or grasp a log utilizing the grasping end around the log's circumference. This can be in the middle of the log or at an end of the log by utilizing the offset rear log support Therefore, one could manipulate a much longer log than the '170 patent because in the present invention the user does not have to grasp both longitudinal ends of the log, just the circumference. Additionally, the user may also drag the log into a desired position.

- The applicant claims the benefit of an earlier filing date as set forth under 35 USC 119(e) in that a provisional application was filed Aug. 31, 2005 as
application number 60/712,782. - Not Applicable.
- 1. Field of the Invention
- The present invention relates generally to the field of implements for tending to a fire, more particularly, to manipulate logs and similar type objects in a fire. Specifically, the present invention is a handling device having a rigid rod inserted through a cavity of a hollow tube, whereby the rod and tube operate independently, a griping end for cradling logs and a handle for manipulating the rod. The present invention is configured in such a way as to allow for gripping, cradling, and manipulation of logs with a minimal amount of energy.
- 2. Description of the Related Art Including Information Disclosed Under 37 CFR 1.97 And 37 CFR 1.98:
- In the past, in order to manipulate a log, a device comprising a rigid rod, grasping end and gripping end would use the mechanism in the gripping end, typically a trigger type of mechanism to control the grasping end. The gripping end required a relatively large force to maintain a grasp on the log, making it difficult for certain classes of individuals to maintain a grasp on the log, or for those who could maintain a grasp to work the device infrequently due to local muscle fatigue, or to manipulate the log with difficulty and in an awkward manner.
- The user would position himself whereby the log and device were perpendicular to each other. The user would then operate a trigger type mechanism on the gripping end that would open and close a grasping mechanism around the circumference of a log. Then the user would manipulate the device to move the log into the position that was desired.
- When the desired position was reached, the user would release his grip on the gripping end, which in turn would be forced open at the grasping end by the weight of the log. The process required strength and coordination to position a log into place. In addition, the log would have to be balanced within the grasping end.
- Also, for particularly large or heavy logs, desired positioning was very difficult. Positioning of logs required strength in the hands and the arms. Leg strength had little effect for positioning of logs with these types of devices.
- There are numerous prior art devices used for positioning objects. For example, U.S. Pat. No. 1,820,463 to Klein, issued on Aug. 25, 1931, teaches the ability to use a mechanical device to pick up and manipulate hot coals and the like. There is a gripping end, grasping end and length between the gripping end and grasping end. The gripping end is mechanically manipulated by squeezing together the mechanical device of the gripping end with the hand. This manipulation of the gripping end translates to movement in the grasping end. As the gripping end is squeezed, the grasping end closes around the desired object to be manipulated, thereby creating a tight grip around the object to be manipulated.
- However, an apparent disadvantage of the '463 patent is that the object that is being manipulated must be relatively small, as the strength of the hands and arms determines the limit of what can be manipulated. This severely limits the device's capabilities. Furthermore, the '463 patent would have difficulties in manipulating any type of object that is long in one dimension while relatively short in the other two dimensions, such as a log.
- To manipulate a log, the user of the '463 patent would have to grasp a long object from an angle perpendicular to the long dimension at a point that would balance the object in the grasping end. Then the user of the device would have used predominately arm strength to manipulate the object into the desired position. For heavy objects, not only would arm strength be required, but also the user would have to apply a required amount of hand strength to the grasping end for the object picked up to remain in the grasp of the grasping end. The amount of strength would depend on the mechanical advantage of the device.
- Lastly, the user would have to be cautious in their manipulation of a long object to maintain the object from dropping on either side (right or left) of the grasping end. Once again, for long or heavy objects, it will be very difficult to control the object.
- The present invention overcomes these limitations. First of all, long objects are picked in a parallel relationship. That is, the length of the device is parallel to the length of the object being manipulated. Therefore, the user can use leg strength to manipulate the position of the object. The object can be cradled or grasped in the grasping end and carried or dragged backwards.
- Additionally, where the object is a log in a campfire, the log can be dragged right or left around the fire. For heavy or long objects, if an end of the log is on the ground, the manipulation of the log would have minimal effect. The present invention does not need, but may, balance the manipulated object by lifting it completely off the ground.
- Furthermore, the present invention does not require squeezing to grasp an object. A torsional action, which requires much less strength, may be used to cradle the manipulated object. Also, the present invention allows for strength to be used for different movement. That is, one hand can manipulate the torsional action to control the grasp of a log, while the other hand manipulates the other axises—right, left, up and down. Also, depending on how far one grasps the rod, one can lift a much greater amount on the grasping end.
- Furthermore, the angle of the gripping end allows for the grasping end to naturally close due to gravity. Lastly, the curvature of the claws allows the log to sit in place, as if being cradled, with minimal amount of torsional force. Most of the torsional force will be to hold the claws together and is minimally affected by the weight of the object being manipulated.
- U.S. Pat. No. 2,429,046 to Billig issued on Oct. 14, 1947, discloses a device for dual action as a poker and as a tong. As a tong, there is a gripping end, shank and jaw. The opening of the jaw is manipulated by secondary grip that slides longitudinally along the shank. This secondary grip allows the user to manipulate heavier objects through the use of two hands.
- However, with heavier objects, because the action is longitudinally, the user must place one hand on the gripping end and one hand on the secondary grip. Then to grip an object the user must expend energy pushing in one direction with the grip and an opposing direction with the secondary grip.
- Finally, to actually manipulate the position of an object, the user must now use additional remaining strength in the user's arm to change position of the object being manipulated.
- Also, the position of the secondary handle is determined by how far open the jaws must be to grasp the manipulated object. Hence, for large and presumably heavier objects, the grip and secondary grips will be in closer proximity than when the manipulated object is smaller, and presumably lighter; thereby, losing the advantage of two hand manipulation for larger, heavier objects.
- The present invention overcomes these limitations by, for example, having a torsional action for cradling or grasping the manipulated object as opposed to requiring opposing forces to grasp the manipulated object, thereby allowing greater amount of strength for manipulating the object than the '046 patent.
- Additionally, the present invention equivalent to a secondary grip is fixed in a non-movable predetermined position that has been determined to provide the best leverage for manipulating objects for the size of objects the device was designed to manipulate. Finally, the present invention is positioned parallel to the longitudinal length of the manipulated object, where the '046 patent would be positioned perpendicular to the manipulated object.
- U.S. Pat. No. 4,225,170 to Flynn, issued on Sep. 30, 1980, discloses a log sideloader. The sideloader comprises a jaw, an arm and a lever. The length of the log will determine how large the jaw is opened. The jaw is manually adjusted until the jaw opening is slightly larger than the log. The lever is mechanically attached to the jaws, such that when the lever is operated the jaws will close, forming a friction fit on the log. Then the log may be manipulated.
- The side loader is designed such that the user operates the sideloader from the side. However, to manipulate a log longitudinally, the sideloader jaw must frictionally engage both ends of the log longitudinally. In this configuration, the length of the arm would determine the length of the log to be manipulated. For this particular device, the length of the log manipulated would be relatively short. Because of the cantilever method of lifting the log, as the longer the log is that is to be manipulated, the quicker it becomes difficult to manipulate ever-increasing log lengths.
- The present invention is designed such that the user may operate the invention from where the log is cradled or grasped. Hence, a user may cradle or grasp a log utilizing the grasping end around the log's circumference. This can be in the middle of the log or at an end of the log by utilizing the offset rear log support Therefore, one could manipulate a much longer log than the '170 patent because in the present invention the user does not have to grasp both longitudinal ends of the log, just the circumference. Additionally, the user may also drag the log into a desired position.
- An object of the present invention to provide a novel and improved manipulating device to facilitate manipulation of objects, such as firewood in a bonfire. The present invention provides a device for cradling or grasping longitudinally long objects around the circumference of the object to drag the object to a desired location. Additionally, the invention to provides a device that requires a fraction of force used in present inventions for cradling or grasping a heavy object.
- Another object of the present invention to provide a device whereby the user can maximize strength of the arms and legs to manipulate an object. The invention to allows the user to grasp or cradle an object where grasp is not primarily dependent on the weight of the object. Additionally, the present invention provides a device where the unique shape of the handle allows greater control over the device while providing ease of use of the device.

FIG. 1 , a preferred embodiment of thepresent invention 10 contains ahollow tube 100, arigid rod 200 inserted through acavity 300 of thehollow tube 100, whereby therod 200 andtube 100 operate independently, agrasping end 400 for grasping or cradling logs and ahandle 500 for manipulating therod 200. Thehollow tube 100 is made from a material that will protect the user's hand from heat that may be transmitted through therod 200 and thehollow tube 100 from the object being manipulated. - The
grasping end 400 may contain a plurality ofclaws 410 which may be attached to thehollow tube 100 by a variety of means as one skilled in the art would use. This includes, but is not limited to welded, riveted, crimped, and cast. Additionally, a plurality ofclaws 420 may be attached to therod 200 by similar means. The plurality ofclaws 410 on thetube 100 and the plurality ofclaws 420 on therod 200 would oppose each other when employing an opposing torsional force to thehollow tube 100 androd 200 to grip or wrap around an object to be manipulated. Thecurvature 450 of theclaws claws handle 500 to hold the log within the grasp of the claws. - The length of the
rod 200 would relate to the size of the objects to be manipulated for a corresponding size device. Additionally, the minimum diameter and thickness of therod 200, although therod 200 is not necessarily solid, is determined by load requirements that are necessary to achieve the objects of the invention. - The
handle 500 size, shape, angle, bend, and offset from center line of therod 200 will depend on the desire of a particular model of the present invention. However, the offset of thehandle 500 from the centerline of therod 200 is a key design feature for minimizing the force a user must use and maintain to hold, cradle, and manipulate the log within theclaws bend 550 in thehandle 500 will provide stability and ease of use of the present invention. Several of these designs are indicated in the drawings; however, one skilled in the art will realize that others variations not shown may be employed to reach a desired goal of ease of use, maximization of manipulation with minimal force, efficiency of use, and efficiency of manufacture. - Finally, although the present invention may be made from metal, this is not a necessary requirement. The present invention may be made from any material that will withstand the temperature and load requirements that are necessary to achieve the objects of the invention.
