44 down into slot 24 it will then be locked in place under the same principles as described above fig1 shows slotted stick 22 with four removable rungs 38 in place as noted above inclined holes 26 alternate in orientation along with the insertion slots 36 to allow the rungs to alternate fig1 b shows two slotted sticks 22 stacked together the reader will observe that the alternating pattern of removable rungs 38 continues through the stack of two or more slotted sticks 22 in actual use a stack of four or more slotted sticks 22 would be placed on the tree 10 or other object to be climbed the sticks 22 are attached to the tree 10 using the securing straps 18 which are well known in the prior art all removable rungs 38 would be removed before leaving the device unattended a user wishing to climb the device would need to bring along a set of removable rungs 38 the user would then progressively install removable rungs 38 as he or she ascends the ladder when the user later descends the ladder removable rungs 38 would be progressively removed a rung to rung spacing of 9 inches in typical for this type of device accordingly in order to ascend a twelve foot object the user would need to bring approximately sixteen removable rungs 38 these rungs 38 can be made of aluminum alloy resulting in a modest weight for a set of sixteen material selection is important for slotted sticks 22 as it must withstand significant mechanical forces it must also withstand prolonged exposure to sunlight and temperature extremes many metals could be used but since the device must often be carried into the woods on.
