Description

BACKGROUND

The following relates generally to transporting material, and more specifically to transporting material using a gravity driven pulley system.

There are many systems for transporting materials. Wood, firewood, and other materials are transported in a wooded area such as a forest, for example. Transporting materials between two locations can be repetitive. Carrying certain materials over a large distance can be heavy. Depending on the number and heaviness of the materials, transporting materials may require more than one person to perform the job, which may be inefficient.

SUMMARY

A method for transporting material using a gravity driven pulley system is described. The method may include moving the material from a first location to a second location using a transport pulley secured to a cable and detaching the transport pulley from the cable at the second location, wherein the transport pulley is detached by a momentum of the transport pulley bringing the transport pulley into contact with a derailer attached to the cable.

Some examples of the method described above may further include securing the material to the transport pulley. Some examples of the method described above may further include placing a pulley wheel of the transport pulley onto the cable such that the pulley wheel may roll along the cable.

Some examples of the method described above may further include connecting the cable at a first end point and a second end point such that it extends from the first location to the second location. Some examples of the method described above may further include adjusting the tension of the cable using a tensioner.

In some examples of the method described above, the first location is at a higher altitude than the second location, and the material is transported by the force of gravity acting on the transport pulley and the material to pull the transport pulley along the cable.

Some examples of the method described above may further include pushing the transport pulley off of the cable using the derailer using a sloped surface of the derailer, wherein the pushing causes the transport pulley to be detached from the cable.

DETAILED DESCRIPTION

FIG. 1 shows an example of a material transport system 100 in accordance with aspects of the present disclosure. In certain embodiments, the material transport system 100 may include a cable 105, a transport pulley 110, a derailer 115, a tensioner 120, an anchoring device 125, a support structure 130, and a material 135.

The material transport system 100 may be used to transport material 135 from one location to another using the force of gravity. It may be configured such that the material 135 may be transported along a cable 105, and then detached from the cable 105 automatically. This may enable the system to be operated by a single user.

The cable 105 is connected between two structures. These structures can be trees. The cable 105 supports a derailer 115 and a transport pulley 110. Tension is introduced to the cable 105 with a tensioner 120 to support the material 135 being transported.

The tensioner 120 is used to introduce tension to the cable 105. In some cases, the tensioner 120 includes a turnbuckle type attachment. In some cases, the tensioner 120 includes a vice grip attachment. In some cases, the tensioner 120 includes a ratchet-type attachment. In some cases the tensioner 120 includes a plurality of elements that are folded and locked together to introduce tension.

The transport pulley 110 holds the material 135 to be transported. The material 135 or load is attached to the transport pulley 110. The transport pulley 110 has a pulley wheel, which rides along the cable 105. The transport pulley 110 has a frame, that is attached to the material 135 to be transported.

The derailer 115 is attached to the cable 105. The derailer 115 includes a lock that secures it to the cable 105. The transport pulley 110 impacts the derailer 115, which derails the transport pulley 110 from the cable 105. The derailer 115 is placed at a second location so that the transport pulley 110 holding the material 135 is deposited at the second location. The transport pulley 110 may be derailed, or the material 135 may be pushed off of the transport pulley 110.

In certain embodiments, the material transport system 100 includes moving the material 135 from a first location to a second location using a transport pulley 110 secured to a cable 105. In some examples, the first location is at a higher altitude than the second location, and the material 135 is transported by the force of gravity acting on the transport pulley 110 and the material 135 to pull the transport pulley 110 along the cable 105.

Derailer 115 may also push the transport pulley 110 off of the cable 105, where a sloped surface of the derailer 115 pushes and causes the transport pulley 110 to be detached from the cable 105.

Derailer 115 may also be connected to the cable 105 and configured to detach the transport pulley 110 from the cable 105. In some examples, the derailer 115 comprises a longitudinal opening, wherein the longitudinal opening is adapted for passage of the first cable 105.

In this case, the tensioner includes a ratcheting mechanism.

In some examples, the locking element is configured to lock the first element and the second element in a locking position. In some examples, the tensioner 120 further comprises a third element having an elongated body, wherein a first end of the third element is pivotably attached to a second end of the first element.
