Abstract

" In tools used for hiking and camping, it is known to use walking sticks, survival packs, stools, brush axes, brush saws, splitting axes, bucking saws and shovels. In this invention, a walking stick with six hollow sections made from three lengths of tubing is broken down and reconstructed to form either a stool, a brush axe, a brush saw, a bucking saw, a splitting axe, or a shovel. As well as holding survival rations, the six compartments will hold most of the necessary parts to construct these tools."

Description

Specification:
" This invention relates to a mufti-purpose tool system that can be used for hiking and back packing excursions,"
" It is common practise when hiking to take along various tools to make the excursion both more comfortable and safe for the participant. Walking sticks, survival packs, stools, brush saws, brush axes, splitting axes bucking saws, and shovel heads, are all manually operated tools that the hiker has uses for. These tools have all been manufactured in various designs for hundreds of years. each tool is made independently and the parts from one tool are not interchangeable with the others. As a result, if the user requires all eight tools, they must pack all eight tools from camp site to camp site. This produces very heavy loads and as a result, often only one is taken."
"I have found that these disadvantages may be over come by providing three sections of tubing which can be assembled into all eight tools with the addition of small parts specific to the tool the user wishes to construct. In addition each tube is divided into two sealed compartments where most of the required parts and survival gear can be stored.
By using modern metal alloys and plastics the dlisadvantage of weight can be further reduced. The result of this invention is that each hiker will be able to convert their walking stick into all the tools and supplies needed for a comfortable over night stay whenever the need arises."

Fig. 15 shows a sixth embodiment, Fig. 16 shows a bottom view of this embodiment and Fig. 17 shows an seventh embodiment of this invention."
" The walking stick illustrate in Fig. 1 is comprised of three lengths of hollow tubing 1,.
Each of the two end pieces of tubing :l are plugged at one end using an end plug assembly shown in Fig. 2. This end plug assem~~ly is comprised of a solid piece of materiel which has a threaded bolt extending form one end, a slot 32 around the outside at the other end and a step 33 partway along it's length. A spacer 7, made of compressible materiel is slid over the bolt and the threaded disc 6, is then threaded onto the bolt and fastened with screws 8. The assembly is then slid into tube 1, to step 33, and the bolt is turned which (2) then causes the compressible materiel 7, to expand and bond with the walls of the tube I .
At the other end of tubel, and at both ends of the centre tube l, is a centre plug assembly which consists of a fastening bolt 11, over which is slid a compressible spacer 7 and a disc 6 is threaded onto bolt 1 l and fastened with screws 8. This assembly is then slid into tube 1, and fastening bolt, 11 is turned and compressible spacer 7, expands to grip and seal against the sides of tube 1. Now that .each end of tube pieces 1, have been sealed and fastening devices secured, the walking; stick is assembled by threading coupler 4 over fastening bolt 11, of one end tube and threading fastening bolt 11 of centre tube l,into coupler 4. A second coupler 4, is then threaded onto the fastening bolt 11 of the second end of the centre tube l, and threaded fastener 11, of the end tube 1 is then treaded into the second coupler 4. All threaded couplers are then tightened.
To construct the stool embodiment shown in Fig. 7, start with all three sections of tube 1 complete with plug assemblies. Thread each threaded hole 10 onto bolt 5 and place cap 12 over fastening bolt 11, of centre tube 1. Place rope loops 15, at corners of fabric piece l3,over fastening bolts 11, and secure; with caps 12.
To construct the brush axe or brush saw embodiment shown in Fig. 10, take one end section of tubing 1, complete with end plug and centre plug assemblies and thread blade back 17 onto fastening bolt 11. Open out blade supports 18 and fasten blade 21 to ends of supports 18, using pins 22. Tighten a:;sembly using tightening device 19.
To construct the buck saw embodiment of this invention start with all three sections of tubing 1, complete with plug assemblies in place. Thread the pivot assembly shown in Fig.
14 onto each fastening bolt 11 of centre piece tubel and tighten. Thread the blade attachment section 26 onto the fastening bolt 11 of each end tube 1. Place hole in blade 27 through anchor pin 28 at each end. Aiaach tightening device 29 in slats 32 and tighten.
To construct the splitting axe embodiment of this invention, start with one end section of tubing 1, complete with end plug assembly and centre plug assembly. Simply thread hole 30 of head 29 onto fastening bolt 11.
To construct the shovel embodiment Shown in Fig.17, start with one end section and the centre section of tubing 1 complete with plugs. Join the end and centre sections together using coupler 4 and tighten. Join shovel 34 by threading fastening bolt I l, into hole 35, and tightening,"
