Even though the blower is an efficient tool that facilitates the work of cleaning large areas, the operator normally works long shifts with the blower. There are two different types of blower, smaller ones that are hand held and larger models that are carried on the back of the operator in order to improve working conditions for the operator.

A blower carried on the back of the operator is supported by a harness. It is important that the harness is comfortable and ergonomic for the operator since the operator is working long shifts with the blower on his back. The harness normally comprises two straps that extend around the shoulders of the operator. Some harnesses also include a waist belt. The waist belt reduces the loads in the straps extending around the shoulders of the operator so that the working condition for the operator is improved.

A combustion engine powered tool is normally very reliable and safe for the operator to carry and handle, but accidents could still happen with the engine or other components in the machinery if they not work as intended. Accidents on the machinery in combination with the inflammable fuel for the engine expose the operator to a high risk if the tool starts burning. This is very serious especially since the tool is strapped to the back of the operator.

Known models of harnesses for blowers are provided with a release mechanism on one of the straps extending over the shoulders of the operator. The release mechanism is placed in the lower end of the strap. The operator activates the release mechanism that

is placed where the strap is secured to the blower. The operator releases the mechanism by pulling a locking pin so that the end of the strap is released from the blower.

Most blowers on the market are not provided with a waist belt but if they are, the waist belt is released at the same time as the strap around the operator's shoulder is released.

This solution for releasing the blower from the operator's back is complicated for the operator to activate since it is difficult to find the release mechanism in a stressed situation. This is not acceptable if an accident occurs to the engine or other components in the machinery since the operator is exposed to a high risk as long as the blower is strapped to his back. Another drawback with the known harnesses is that it is easy to activate the release mechanism unintentionally because of the position of the mechanism close the operator's hip where the release mechanism could fastens to something so that the locking pin is released.

The harness for blowers carried on the back of the operator must therefore be improved to increase the safety for the operator if the engine or machinery of the blower not is working as intended.

A harness with the features defined in the independent claim solves the described problem.

One of the straps extending around the shoulder of the operator, on the claimed harness, consist of an upper padded section secured to the tool and a belt connected to the padded section somewhere along the padded section where it is easy for the operator to reach. The belt is extending downwards and passing through a loop secured in to the lower part of the tool. The belt is then used as a section of the waist belt so that when the belt is released from its connection to the upper padded section will the belt slide through and out of the loop. The strap around the shoulder of the operator is opened by a buckle placed somewhere along the upper padded section where it is easy for the operator to find. When the buckle is opened is the belt released from the padded section.

The belt then slide in the loop so that one side of the waist is belt released from the tool.

The buckle is opened by one single action by the operator. This action is easy and quick for the operator to perform and releases both the strap around the shoulder as well as the waist belt.

The belt is connected to the padded strap by a buckle preferably placed close to the lower end of the padded strap on the side of the strap facing away from the operator.

The operator releases the belt and consequently also the waist belt by opening the buckle placed somewhere close to the chest of the operator. This solution makes it very easy for the operator to release the tool in case of an accident to the tool.

The claimed harness can be improved further by providing the straps that extends around the shoulders of the operator with a third strap extending between the two straps around the operators shoulders. The third strap is placed on the chest of the operator and pulls the two straps together so that the wear on the operators shoulders are reduced.

The end of the third strap that is fastened to the strap that is released in case of an accident is provided with a loop. The belt secured to the padded section of the strap is passing through the loop so that when the operator releases the belt from the padded section will also the end of the third strap be released to make it easy for the operator get rid of the tool.

One embodiment of the claimed invention is illustrated in the drawings.

Figure 3. Illustrates the loop on the lower section of the tool.

Figure 4. Illustrates the strap and the section of the waist belt that is released to make it possible for the operator to remove the tool quickly.

In figure 1 is a harness 10 illustrated. The harness 10 comprises a first and a second strap 11 and 12 that extend around the shoulders of the operator when the tool is placed on the back of the operator. The first strap 11 consist of a first padded section 13 and a first belt 14 secured to the end of the padded section 13 with one end and the lower part of the not illustrated tool with the other end. The length of the strap is adjustable to fit the operator.

The second strap 12 comprises a second padded section 15, a second belt 16 extending from the lower end of the padded section 15 and a buckle 17. The other end of the padded section 15 is fastened to a padded plate 30 in the top section of the not illustrated tool. The buckle 17 is attached to the padded section 15 of the strap 12 and secures the belt 16 to the padded section 15. The end of the belt 16 is pressed between a first 31 and a second 32 part of the buckle 17 so that the belt 16 is fastened by the friction between the first part 31 of the buckle 17, the second part of the buckle 17 and the belt 16. The belt is extending downwards along the padded section 15 and passing through a couple of passages 33 to keep the belt 15 in the right position along the padded section 15. The other end of the belt is passing through a loop 18 secured in the lower part of the not illustrated tool. The end of the belt 16 is then used as a firs section 19 of a waist belt 20. The waist belt also includes a second section 21. The first and the second section are secured to each other by a snap-buckle 22 that makes it easy to secure as well as open the waist belt 20 when the operator wants to put on or off the tool. The length of the waist belt 20 is adjusted so that it fits around the waist of the operator and reduces the loads on the operator's shoulders.

The harness 10 also comprises a third strap 23 extending between the first and the second strap 11 and 12. The third strap 23 is placed on the chest of the operator and pulls the first and the second strap 11 and 12 together so that the wear on the operators shoulders are reduced. The end of the third strap that is fastened to the second strap 12 is provided with a loop 24. The second belt 16 secured to the second padded section 15 of second strap 12 is passing through the loop 24. The other end of the third strap 23 is permanently attached to the first strap 11. The third strap 23 is provided with a third snap-buckle 25 that makes it possible to open the strap 23 so that the operator can put on and off the tool from his back.

The lower end of the second strap 12 is provided with a section of second snap-buckle 34. If the operator, for some reason, not is interested in using the waist belt is the first section 19 of the waist belt 20 connected to the second snap-buckle 34. By doing so the release mechanism will still work as intended for the strap 12 around the operator's shoulder and the third strap 23 on the chest of the operator.

The embodiment illustrated in the drawings and described in the text makes it possible for the operator to release the tool easily from his back in case of an emergency. The harness is released by opening the buckle 17 so that the belt 16 is released from the padded section 15. The belt 16 then slide trough and out of the loop 18 so that also the waist belt 20 is opened and the harness 10 released from the operator. The third strap 23 on the operator's chest is released as soon as end of the belt 16 is passing through the loop 24 in the end of the third strap 23.

This means that on of the straps extending around the shoulders of the operator, the waist belt 20 and the strap 23 on the operator's chest are released from the operator by one single action from the operator. The claimed harness increases the safety for the operator and is ergonomic.
