LOG HAULER
BACKGROUND OF TFIC INVENTION

1. Field of the lnvention 10 The present invention relates to a log hauling device. More particularly, the present invention relates to a log hauling device for use with a four wheeler or similar vehicle to remove logs from the bush in a secure and safe nlanner.

2. Prior Art Many different types of log hauling devices and methods are known for removing logs from a wooded area.

One of the more common metliods utilized by individuals for removing logs from the bush is to secure one end of a chain or rope to a log to be removed with the other end of the chain or rope secured to a vehicle for towing the log. This is a cunlbersome and 20 time consuming method. It is often difficult to wrap a chain or rope around a log and tie the same around the log to securely hold the log. Further, it is often difficult and time consuming, once the log has been towed to the desired location, to remove a chain/rope which has been secured around a log .

U.S. Patent 6,675,848 to Chai discloses an apparatus for conveying timber which utilizes a sledge with a base portion of a curved configuration. A log is placed within the base portion of the sledgc and a swing chain is wrapped around the timber to secure it to the sledge. A winching cable is also tied around the tiniber. 'The winching cable is then retracted to pull the sledge and the log attached thereto to a desired location.

U.S. Patent 3,517,839 to Jorgensen discloses a log skidding device for towing logs utilizing a towing vehicle. 'I'he log skidding device comp--ises a skid pan having teeth at the base thereof and a traiisverse clamping jaw for retaining a plurality of logs thereon. The skid pan is connected to a towing vehicle through a winch rope.
'I'he skid pan rests on the ground for the loading of the logs. Oncc the logs are loaded, the winch of the towing vehicle is started thereby puIling the skid pan with the loaded logs up from the ground to the rear end of the towing vehicle.

U.S. Patent 3,086,666 to Larson also discloses a log towing apparatus which utilizes a skidder means connected to a towing vehicle by a tow frame. The skidder means is adapted for the loading of a plurality of logs. The apparatus utilizes a cable and winch arrangement for towing the logs behind the tow vehicle.

DETAILED DESCRIPTION OF THE INVL;NTION

The log hauler, generally designated by reference numeral 10, of the present invention enables the hauling of small logs out of the bush behind a truck or four wheeler all terrain vehicle (ATV) in a simple and secure manner.

Referring initially to Figures l to 3, the log hauler 10, includes a log carriage 12 which is slidably mounted on a frame member 14. 'fhe fi-aine niember 14 has a proximal portion 34 and a distal portion 35. 1'he proxinlal portion 34 includes means, generally designated by reference numeral 40, for connection to a tow vehicle, such as an all terrain vehicle (ATV). The log carriage 12 is mounted to the frame member 14 through member 38 which perniits the sliding movement of'the log carriage 12 along the fratne 14, in such a nlanner that it can be moved from a retracted position where the log carriage 12 is in a position closer to the proximal end 34 of the frame member 14 (as best seen in Figure 2) to a fully extended position where the log carriage 12 is at a position adjacent to the distal end 35 of the frame 14 (as best seen in Figure 3).

A pull or tow ring 55 is provided at the distalmost end of the frame 14. The tow ring 55 can be used if it becomes necessary to pull the tow vehicle, sueh as for example, if the tow vehicle beconies stuck in the nlud or otherwise. The tow ring 55 could also be utilized to pull a log from a location difficult to access to a location where one can easily load the log onto the log carriage 12. This would be desirable, for instance in the case where a log is across a river. A chain can be secured to the log and then to the tow ring 55 and the tow vellicle could t11en pull the log across the river to a location where the log cold be easily loaded onto the log carriage 12.

The frame 14 is also provided with stop menibers thereon adjacent to the distal and proximal ends to limit the sliding movenlent of the log carriage 12 on the frame 14.
In this regard, a portion of the tow ring 55 could form a stop at the distal end of the frame 14 and the area of the plates 57 and 59 (which will be discussed hereinafter) could fornl a stop adjacent the proximal portion of the 1i-anie 14.

The log carriage 12 is generally arcuate ot= has a generally U-shaped configuration and is adapted to receive one end of a log therein. The log carriage 12 includes a back wall 15 which acts as a stop to prevent movement of the log beyond the back wall 15 and an open front end to permit an end of the log to protrude therefrom.

Preferably, the log carriage is composed of steel sheeting although other suitable materials could be utilized. Preferably, the log car-riage 12 is about 7 inches to 11 inches (18cm to 28 cm) in length. A particularly preferred length being about 9 inches (23 cm).
In preferred embodiments, the side walls of the log carriage 12 are approximately 3- 4 inches (about 7.5 cm to 10 cm) high.

The frame member 14 can be composed of steel tubing. Preferably, the frame has an overall length of about 13 inches to 24 inches (about 33 cm to 61 cm).
In particularly preferred arrangements, the framc has a length of about 16 inches to 22 inches (about 40.5 cn1 to 56 cni).

The log carriage is also provided with a plurality of spikes or teeth 24 arranged in the interior thereof. The spikes or teeth 24 grip the log and aid in securing the log in position on the log carriage 12. 'I'he teeth 24 can be of any suitable material and size. In preferred arrangements the teeth are cotnposed of stainless steel and have a height of approximately 1 inch (2.5 cm). In other preferred arrangements, the teeth are at a 45 degree angle with respect to a surface of the log carriage 12.

A safety bar 16 is pivotably mounted at a top of said log carriage 12 on opposed sides thereof ."I'he safety bar 16 consists of two side bars 20a and 20b, one on each side of the log carriage 12, which are mounted to the sides of the log carriage 12 at pivot point 18 and which are joincd by a cross bar 22 which extends across the top at the front end of the log carriage 12 when the safety bar 16 is in the lowered engaged position.
When the log hauler 10 is in use with a log secured within the log carriage 12, the safety bar 16 is pivoted to an open position where it rests in a non-use position adjacent the back wall 15 of the log carriage 12 . Once the log is removed from the log carriage 12, the safety bar 16 is returned to the forward lowered position at the front of the log carriage 12 and acts as a guard to prevent an individual from falling onto the spikes 24 within the bottom of the log carriage 12.

The safety bar can be of any suitable material or dimension. In preferred arrangements, the safety bar is composed of steel tubing.

The log carriage 12 is also provided with chain guide loops or eyes 26, 27 on opposed sides of the log carriage 12 for receiving and guiding a securing chain 28. The securing chain 28 extends from a retention loop 30 on one side of the frame 14, and in use is threaded through the cliain loop 27, over the log within the log carriage 12, through the chain loop 26 on the other side of the log carriage 12 and then is secured to a chain slot 32 which is located on the side of the frame 14 opposite to the retention loop 30. The chain can be any desired heavy duty chain of a suffcient length to secure the log as noted above. An example of a suitable chain is a 1" (2.5 cm) grade 30 steel chain.
The eye loops 26, 27 are of a suitable size to easily accommodate the desired chain.

As best seen in Figures 4 and 5, the distal portion 35 of the frame 14 on which the log carriage 12 is slidingly mounted is movable in an upward direction relative to the proximal portion 34 of the frame 14 through pivot point 43 and connection plates 57, 59 connecting the distal portion 35 and proximal portion 34 of the frame together.

Further, the frame 14 is also pivotable in a side to side manner with respect to the tow vehicle, as is best shown in Figure 6.

The connection means 40 of the frame 14 can be any suitable connection means for connection of the frame 14 to the desired tow vehicle. As an example, the connection means 40 can be in the form of a bolt 50 and slot arrangement 52 as best shown in Figures 1, 2 and 4, where the bolt and slot arrangement provides for the side to side pivoting movement of the log hauler 10 with respect to the tow vehicle. An alternative connection means 40 could be in the form of a receiver/hitch type arrangement as best shown in Figures 3 and 5.

Also provided on the proximal portion 34 of the frame 14 are opposed stop members 42, 44 to prevent the log hauler 10 from swaying to the extreme left or right relative to the tow vehicle.

Referring now to Figure 7, when in use, the log hauler 10 is connected to a tow vehicle 46, typically a four wheel ATV. To load the log to be removed, the tow vehicle 46 is backed up to the log 48. With the log carriage 12 in the retracted position (towards the proximal portion 34 of the frame 14), the safety bar 16 is raised and positioned into its l0 non-use position adjacent to the back wall 15 of the log carriage 12. The end of the log 48 is positioned within the log carriage 12 with the end of the log 48 close to or abutting the back wall 15. The securing chain 28 is fed through the eye loop 27, over the. log and through the eye loop 26. The chain 28 is then tightened and secured to the chain slot 32.
Once the securing chain 28 is secured, the vehicle 46 can be driven forward.
As the vehicle 46 moves forward, the log carriage 12 starts to slide into a fully extended position (towards the distal end 35 of the frame 14) due to weight of the log 48 and the forward momentum of the vehicle 46. This movement of the log carriage 12 serves to tighten the chain 28 onto the log 48 which in turn pulls the log 48 down onto the spikes or teeth 24 which aid in gripping the log 48. The log 48 can then be towed from the bush to the desired location.

Once the log 48 is towed out of the bush and one desires to unhook the log 48, the vehicle 46 is simply backed up a little, which causes the log carriage 12 to slide back into the retracted position, which in turn allows the chain 28 to loosen somewhat permitting easy and quick removal of the chain 28.

Once the log is removed, the safety bar 16 is then returned to its engaged position at the front of the log carriage 12 to guard against any one inadvertently falling onto the log carriage 12 and injuring themselves on the spikes 24.

While the invention has been described in detail and with reference to preferred embodiments thereof, it will be understood that various modifications and changes can be made therein without departing from the spirit and scope of the invention.
