Description

Cutting Tool

TECHNICAL FIELD

The present disclosure relates to handheld cutting tool comprising a power source configured power a cutting member of the handheld cutting tool.

BACKGROUND

Cutting can be performed using different types of cutting tools, such as chainsaws, circular saws, jigsaws, and the like. Different types of cutting tools are associated with different advantages and disadvantages and a cutting tool is normally best suited for performing a certain cutting task.

Cutting tools of various types are associated with some mutual problem. One problem is ergonomics. That is, it is an advantage if a user can use the cutting tool in a simple an ergonomic manner. Another problem, which is partly liked to ergonomics, is the weight of the cutting tool. That is, it is a great advantage if a handheld cutting tool is designed to have a low weight because the weight of the cutting tool puts strain on hands, arms and back of a user. However, due to the components needed, such as the tool, a power source powering the tool, and the like, it can be difficult to design a cutting tool to have a low weight.

Another problem is safety. That is, a cutting tool is preferably designed such that it can be used in a safe manner. However, sharp cutting edges are needed, and some types of cutting tools are powerful which can make it difficult to obtain a safe cutting tool. Moreover, in order to cut an object using a cutting tool, a cutting unit of the tool must be pressed with some force against the object. This can be difficult to obtain with some tools and in some situations. Moreover, it can lead to dangerous situations when an object being cut is separated because a user risks losing control of the cutting tool when a cut is finished. That is, when a cut is finished and an object being cut is separated, the counterforce obtained by the abutting contact between the cutting unit and the object is removed which may cause the cutting tool to move in unexpected manner in the cutting direction when the cut is finished.

A chainsaw is normally a powerful cutting tool capable of cutting trees and branches in a quick and efficient manner. However, for smaller jobs and more delicate cutting, another type of cutting tool can be more well suited such as a hand saw, or the like. This because a chainsaw requires a relatively powerful power source and are normally heavy and bulky. Moreover, a chainsaw normally provides a relatively rough cut. Therefore, professionals and gardeners normally perform certain tasks with a smaller hand saw, such as for example when cutting smaller branches of a tree, even if they have a chainsaw readily available. Such a smaller hand saw also provides a cleaner and smoother cut. However, the use of a hand saw is burdensome and puts strain on hands and arms of the user.

Another problem for professionals and gardeners is that some branches of a tree are located at a considerable height from the ground surface making them difficult to reach without climbing the tree, using a ladder, a stool, or the like. Climbing a tree and using ladder, a stool, or the like is burdensome, poses a safety risk, and is not ergonomic. Therefore, chain pole saws have been developed by some manufacturers.

A chain pole saw is a cutting tool comprising a pole with a handle portion at one end and a chainsaw unit arranged at the other end. The length of the pole allows a user to cut branches at considerable heights while standing on a ground surface. In this manner, the user does not need to climb the tree or to use a use a ladder, a stool, or the like, to cut the branch.

A chain pole saw can be an efficient tool when cutting branches of a tree. However, chain pole saws are also associated with several problems and drawbacks. One problem is weight. That is, the chainsaw unit requires a guide bar, a cutting chain, and a powerful motor for rotating the cutting chain around the guide bar. Moreover, most chainsaws are provided with a lubrication system configured to lubricate the cutting chain which also adds weight and complexity to the chainsaw unit. Since the chainsaw unit is arranged at one end of the pole, being opposite to the handle portion, the weight of the chainsaw unit usually makes it difficult and burdensome to manoeuvre and support the chain pole saw during cutting.

Moreover, as mentioned above, in order to cut an object using a cutting tool, a cutting unit of the tool must be pressed with some force against the object. Thus, when using a chain pole saw for cutting a branch at a considerable height from the ground surface, it can be difficult for the user to apply such a force onto the branch. Moreover, even if the user is able to apply such a force, it can lead to dangerous situations, for example if the user is slipping. In addition, dangerous situations may occur when the branch is separated from the tree because the user is required to support the saw at the same time the branch is separated from the tree to prevent it from falling towards the ground. Moreover, some users tend to stand under a branch being cut which can be dangerous because of the falling branch. A further problem associated with a chain pole saw is that it is difficult to select a proper cutting direction. Another general problem associated with cutting is that splitting can occur when cutting branches because the weight of the branch may cause a separation of the branch from the three before the branch is completely cut. If so, the branch is usually separated from the tree in directions of the fibrous structure of the wood of the branch. The directions of the fibrous structure of the wood normally differ significantly from a cutting plane of a cutting unit. Therefore, if the branch is separated from the tree before the branch is completely cut, the branch is most likely separated from the tree in an uneven separation plane. Such separations are normally referred to as splitting. If possible, splitting is to be avoided because of aesthetic reasons. Moreover, splitting can have a negative impact on the health of the tree because of a large area of wood being exposed to the surroundings as compared to when a branch is separated from a tree in a planar cutting plane.

As is commonly known among professionals and gardeners, splitting can be avoided by first performing an undercut and then performing an overcut to separate a branch from a tree. An undercut is a cut made in an underside of a branch and an overcut is cut made in an overside of the branch. By first performing an undercut and then performing an overcut the risk of splitting is significantly reduced when the branch is separated from the tree. However, with many tools, such as chain pole saws, it can be impossible, or at least very difficult, to perform an undercut and an overcut in the above described manner.

In addition, generally, on today’s consumer market, it is an advantage if products comprise different features and functions while the products have conditions and/or characteristics suitable for being manufactured and assembled in a cost-efficient manner.

Furthermore, it is an advantage if cutting tools can be designed to be energy efficient because of environmental concerns and because an energy efficient operation can reduce the size of a cutting member and the size of a power source powering the cutting member. In addition, an energy efficient operation can reduce the size of an energy storage unit, such as a fuel tank or a rechargeable battery, while maintaining an available operational time of the cutting tool.

SUMMARY

It is an object of the present invention to overcome, or at least alleviate, at least some of the above-mentioned problems and drawbacks.

According to an aspect of the invention, the object is achieved by a handheld cutting tool comprising a cutting member configured to reciprocate along a reciprocating axis and a power source configured power the cutting member. The cutting tool further comprises a body portion comprising a handle and a tool portion. The tool portion comprises the cutting member and a first abutment having a first abutment surface configured to abut against an object during cutting of the object with the cutting member. The tool portion is pivotally attached to the body portion about a pivot axis.

Since the tool portion of the cutting tool comprises the first abutment having the first abutment surface configured to abut against an object during cutting, the need for a user applied force onto the object is circumvented, or at least reduced. Furthermore, due to the first abutment, the risk of losing control of the cutting tool is significantly reduced during cutting as well as upon separation of an object being cut.

Furthermore, since tool portion is pivotally attached to the body portion about a pivot axis, a cutting tool is provided allowing a user to select a cutting direction in a simple, safe, and convenient manner simply by pivoting the tool portion relative to the body portion and thereby also relative to an object being cut. Thus, due to the combination of the first abutment and the pivoting feature of the tool portion, a cutting tool is provided allowing a user to perform overcuts and undercuts of objects in a simple, safe, and ergonomic manner so as to avoid splitting.

Moreover, since the cutting tool comprises a cutting member configured to reciprocate along a reciprocating axis, a low weight cutting member can be used. Moreover, the cutting member has conditions for performing a clean and smooth cut while consuming a low amount of energy. As a further result thereof, the tool portion of the cutting tool can be made to have a low weight. In addition, a small sized and low weight power source can be used for powering the cutting member. Thus, as a further result of these features, a cutting tool is provided having conditions for having a low weight.

Accordingly, in summary, a handheld cutting tool is provided having conditions for being used in a simpler, safer, and more ergonomic manner.

Accordingly, a handheld cutting tool is provided overcoming, or at least alleviating, at least some of the above-mentioned problems and drawbacks. As a result, the above-mentioned object is achieved.

Optionally, the first abutment surface has a surface normal pointing towards the cutting member. Thereby, the need for a user applied force onto the object being cut is further reduced. This is because the object being cut can be squeezed between the first abutment surface and the cutting member during cutting. As a further result thereof, the cutting tool can be used in a more ergonomic and safe manner.

Optionally, the angle between the reciprocating axis and the first abutment surface is within the range of 30 - 85 degrees or is within the range of 45 - 80 degrees. Thereby, the need for a user applied force onto the object being cut is further reduced. This is because the object being cut can be squeezed between the first abutment surface and the cutting member in an efficient manner during cutting. As a further result thereof, the cutting tool can be used in a more ergonomic and safe manner.

Optionally, the cutting member is configured to cut objects in a cutting plane, and wherein the angle between the pivot axis and the cutting plane is within the range of 60 - 120 degrees or is within the range of 80 - 100 degrees. Thereby, a cutting tool is provided allowing a user to select a cutting direction of the cutting member in a simple, safe, and convenient manner to perform overcuts and undercuts of objects in a simple, safe, and ergonomic manner. In this manner, the user can perform cutting in a manner reducing the risk of splitting.

Moreover, since the tool portion of the cutting tool is pivotally attached to the body portion about the pivot axis, a handheld cutting tool is provided allowing a user to cut objects at considerable heights without having to stand under the object being cut. Thus, a handheld cutting tool is provided allowing the user to cut objects in a safer manner.

In addition, due to the first abutment, a more controlled cutting can be performed and the need for the user to apply a force onto the object being cut is reduced. As a further result, the user is less likely to lose control of the handheld cutting tool when the cut of an object at a considerable height from the ground surface is finished. Furthermore, due to the first abutment, and the fact that the tool portion of the cutting tool is pivotally attached to the body portion about the pivot axis, a user can perform overcuts and undercuts in a simple, safe, and ergonomic manner simply by pivoting the tool portion relative to the body portion during cutting and thereby also relative an object being cut.

Optionally, the body portion comprises a pole being elongated along a direction of elongation. Thereby, a handheld cutting tool is provided having conditions for cutting objects at considerable heights from a ground surface, such as branches of a tree, in a simpler, safer, and more ergonomic manner. Moreover, since the tool portion of the cutting tool is pivotally attached to the body portion about the pivot axis, a handheld cutting tool is provided allowing a user to cut objects at considerable heights without having to stand under the object being cut. Thus, a handheld cutting tool is provided allowing the user to cut objects in a safer manner.

In addition, due to the first abutment, a more controlled cutting can be performed and the need for the user to apply a force onto the object being cut is reduced. As a further result, the user is less likely to lose control of the handheld cutting tool when the cut of an object at a considerable height from the ground surface is finished. Furthermore, due to the first abutment and the fact that the tool portion of the cutting tool is pivotally attached to the body portion about the pivot axis, a user can perform overcuts and undercuts in a simple, safe, and ergonomic manner simply by pivoting the tool portion relative to the body portion during cutting and thus also relative an object being cut.

Optionally, the body portion comprises a handle portion comprising the handle, wherein the handle portion is arranged at a first end of the pole, and wherein the tool portion is pivotally attached to the body portion at a second end of the pole. Since the tool portion is pivotally attached to the body portion at a second end of the pole and has conditions for having a low weight, conditions are provided for a more controllable and ergonomic elongated cutting tool capable of cutting objects at considerable heights from a ground surface.

Optionally, the body portion is elongated along a direction of elongation, and wherein the tool portion is pivotable to a first pivot position relative to the body portion in which the reciprocating axis of the cutting member is substantially parallel to the direction of elongation of the body portion. Since the body portion is elongated along a direction of elongation, a handheld cutting tool is provided having conditions for cutting objects at considerable heights from a ground surface, such as branches of a tree, in a simpler, safer, and more ergonomic manner. Moreover, since the tool portion of the cutting tool is pivotally attached to the body portion about the pivot axis, a handheld cutting tool is provided allowing a user to cut objects at considerable heights without having to stand under the object being cut.

DETAILED DESCRIPTION

Aspects of the present invention will now be described more fully. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.

Fig. 1 schematically illustrates a handheld cutting tool 1 according to some embodiments of the present disclosure. According to the illustrated embodiments, the handheld cutting tool 1 comprises a body portion 2 being elongated along a direction of elongation de. In more detail, according to the illustrated embodiments, the body portion 2 comprises a pole 12. As indicated in Fig. 1, the pole 12 is also elongated along a direction of elongation de.

Accordingly, the handheld cutting tool 1 according to the illustrated embodiments is a type of pole saw. Therefore, the handheld cutting tool 1 , as referred to herein, may also be referred to a pole saw. However, according to further embodiments, the handheld cutting tool 1 , as referred to herein, may have a different shape than the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1. The feature that the handheld cutting tool 1 is “handheld” means that the handheld cutting tool 1 is configured to be supported by one or two hands of a user during operation. The handheld cutting tool 1 according to the illustrated embodiments is preferably supported by two hands of a user during operation, as is further explained herein. The handheld cutting tool 1 is in some places herein referred to as the “cutting tool 1” for reasons of brevity and clarity.

The body portion 2 of the cutting tool 1 comprises a handle 6, 6’. Furthermore, the cutting tool 1 comprises a tool portion 4. The tool portion 4 comprises a cutting member 3. As is further explained herein, the cutting member 3 is configured to reciprocate along a reciprocating axis. According to the illustrated embodiments, the body portion 2 comprises a handle portion 8 comprising a handle 6. The handle portion 8 is arranged at a first end 12’ of the pole 12 and the tool portion 4 is pivotally attached to the body portion 2 at a second end 12” of the pole 12 about a pivot axis. In Fig. 1 , a portion 6’ of the pole 12 is schematically indicated as a second handle of the cutting tool 1. During use of the cutting tool 1 according to the illustrated embodiments, a user may grab the handle 6 of the handle portion 8 and a portion 6’ of the pole 12 to support the cutting tool 1 during operation. The portion 6’ of the pole 12 may thus function as a second handle of the cutting tool 1. The cutting tool 1 further comprises a safety button 16 and a power control actuator 18 arranged at the handle 6 of the cutting tool 1.

Fig. 2 schematically illustrates an enlarged view of the tool portion 4 of the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1. Moreover, in Fig. 2, a section of the body portion 2 of the handheld cutting tool 1 can be seen. Furthermore, in Fig. 2, the cutting member 3 can be more clearly seen. The tool portion 4 comprises the cutting member 3. Moreover, as indicated in Fig. 2, the cutting member 3 is configured to reciprocate along a reciprocating axis Ra. The cutting tool 1 comprises a power source 5 configured power the cutting member 3, i.e. configured to reciprocate the cutting member 3 along the reciprocating axis Ra during operation of the cutting tool 1. Since the cutting tool 1 comprises a power source for powering the cutting member 3, the cutting tool 1 , as referred to herein, may also be referred to as a “power tool”, “a handheld power tool”, “a handheld elongated power tool”, or the like.

According to the illustrated embodiments, the power source 5 is arranged in the tool portion 4 of the cutting tool 1. In this manner, movement between the power source 5 and the cutting member 3 is only needed to be transferred a short distance through the cutting tool 1. According to the illustrated embodiments, the power source 5 is an electric motor. In this manner, a cutting tool 1 is provided having conditions for being manufactured and assembled in a cost efficient manner. In addition, a cutting tool 1 is provided having conditions for a low total weight of the cutting tool 1 as well as a low weight of the tool portion 4 of the cutting tool 1. According to the illustrated embodiments, the power source 5 is arranged inside a housing 4’ of the tool portion 4. According to further embodiments, the power source 5 may be arranged in another manner relative to the tool portion 4. As an example, at least a portion of the power source 5 may protrude out from the housing 4’ of the tool portion 4.

With reference to Fig. 1 , according to the illustrated embodiments, the body portion 2 comprises an electric power supply 17. The electric power supply 17 is configured to supply electricity to the power source 5 during operation of the cutting tool 1. In more detail, according to the illustrated embodiments, the electric power supply 17 is arranged in the handle portion 8 of the cutting tool 1. The electric power supply 17 may comprise a rechargeable battery. Since the electric power supply 17 is arranged in the body portion 2 of the cutting tool 1 , conditions are provided for a more advantageous weight distribution of the cutting tool 1.

As is indicated in Fig. 2, the tool portion 4 comprises a first abutment 10. The first abutment 10 has a first abutment surface 10’. The first abutment surface 10’ is configured to abut against an object 30 during cutting of the object 30 with the cutting member 3. In Fig. 2, an example object 30 is illustrated in dotted lines. The first abutment 10 is arranged such that first abutment surface 10’ is abutting against an object 30 when the object 30 is placed between a first side s1 of the cutting member 3 and the first abutment 10 and the tool portion 4 is pressed against the object 30. As indicated in Fig. 2, according to the illustrated embodiments, the first abutment surface 10’ has a surface normal N1 pointing towards the cutting member 3.

In more detail, according to the illustrated embodiments, the angle a1 between the reciprocating axis Ra and the first abutment surface 10’ is approximately 57 degrees. According to further embodiments, the angle a1 between the reciprocating axis Ra and the first abutment surface 10’ may be within the range of 30 - 85 degrees or may be within the range of 45 - 80 degrees. Thereby, the tool portion 4 of the cutting tool 1 can be securely retained against an object 30 during cutting thereof, as is further explained herein.

As mentioned above, and as is indicated in Fig. 2, the tool portion 4 is pivotally attached to the body portion 2 about a pivot axis Pa. In Fig. 2, as well as in Fig. 2, the cutting tool 1 is illustrated in a viewing direction coinciding with a direction of the pivot axis Pa. Moreover, as indicated in Fig. 2, the cutting member 3 is configured to cut objects 30 in a cutting plane Pc. In Fig. 2, the cutting plane Pc is perpendicular to the viewing direction of Fig. 2. The cutting member 3 has an intended cutting direction which extends in the cutting plane Pc. According to the illustrated embodiments, the angle between the pivot axis Pa and the cutting plane Pc is 90 degrees. According to further embodiments, the angle between the pivot axis Pa and the cutting plane Pc may be within the range of 60 - 120 degrees or may be within the range of 80 - 100 degrees. This angle is indicated and further explained in Fig. 4.

Moreover, according to the illustrated embodiments, the reciprocating axis Ra of the cutting member 3 extends through the pivot axis Pa regardless of the pivoting position of the tool portion 4 relative to the body portion 2. According to further embodiments, the cutting tool 1 may be arranged such that the smallest distance dO between the reciprocating axis Ra and the pivot axis Pa is smaller than 10 cm or is smaller than 5 cm. As understood from the above described, according to the illustrated embodiments, the smallest distance dO between the reciprocating axis Ra and the pivot axis Pa is zero centimetres.

In Fig. 2, the direction of elongation de of the body portion 2 is indicated. Moreover, in Fig. 2, the tool portion 4 is illustrated in a pivot position relative to the body portion 2 in which the reciprocating axis Ra of the cutting member 3 is parallel to the direction of elongation de of the body portion 2. Thus, according to the illustrated embodiments, the tool portion 4 is pivotable to a pivot position relative to the body portion 2 in which the reciprocating axis Ra of the cutting member 3 is substantially parallel to the direction of elongation de of the body portion 2. This pivoting position is below referred to as the first pivoting position of the tool portion 4. In Fig. 2, the cutting tool 1 is illustrated from a first side.

Fig. 3a illustrates a second side the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1 and Fig. 2 in which the tool portion 4 has been pivoted to a second pivot position relative to the body portion 2. The second side of the handheld cutting tool 1 is opposite to the first side of the handheld cutting tool 1 .

As can be seen in Fig. 3a, according to the illustrated embodiments, the cutting tool 1 comprises a resilient member 13. The resilient member 13 is configured to bias the tool portion 4 of the cutting tool 1 towards a predetermined pivot position relative to the body portion 2. According to the illustrated embodiments, the predetermined pivot position coincides with the first pivot position illustrated in Fig. 2. That is, according to the illustrated embodiments, the resilient member 13 is configured to bias the tool portion 4 of the cutting tool 1 towards a pivot position in which the reciprocating axis Ra of the cutting member 3 is substantially parallel to the direction of elongation de of the body portion 2.

In Fig. 2, the resilient member 13 is hidden behind the body portion 2. As can be seen in Fig. 3a, the resilient member 13 is connected to a portion 22 of the body portion 2 and to a portion 14 of the tool portion 4. The portion 14 of the tool portion 4 is located at a distance from the pivot axis Pa at a side of the tool portion 4 being opposite to the cutting member 3. The resilient member 13 is configured to apply a contracting force between the portion 22 of the body portion 2 and the portion 14 of the tool portion 4. In this manner, the resilient member 13 biases the tool portion 4 towards the predetermined pivot position relative to the body portion 2, i.e. towards the first pivot position illustrated in Fig. 2 according to the illustrated embodiments.

The resilient member 13 may comprise an elastic body, a spring, a coil spring, or the like. According to further embodiments, the cutting tool 1 may comprise another type of resilient member 13 configured to bias the tool portion 4 towards a predetermined pivot position relative to the body portion 2, such as for example one or more resilient members arranged inside the housing 4’ of the tool portion 4 of the cutting tool 1. Moreover, according to some embodiments, the resilient member 13 may comprise a damper arranged to damp pivoting movement between the tool portion 4 and the body portion 2.

As can be seen in Fig. 1. The body portion 2 of the cutting tool 1 is significantly longer than the tool portion 4 of the cutting tool 1. In more detail, according to the illustrated embodiments, the length L1 of the body portion 2 measured from a first end T of the cutting tool 1 to the pivot axis Pa is approximately 8.3 times greater than the length L2 of the tool portion 4 measured from a second end 1” of the cutting tool 1 to the pivot axis Pa. According to further embodiments, the length L1 of the body portion 2 measured from a first end T of the cutting tool 1 to the pivot axis Pa may be at least two times greater, or may be at least four times greater, than the length L2 of the tool portion 4 measured from a second end 1” of the cutting tool 1 to the pivot axis Pa.

According to the illustrated embodiments, the total length L1 + L2 of the cutting tool 1 measured between the first end T of the cutting tool 1 and the second end 1” of the cutting tool 1 is approximately 6 meters. According to further embodiments, the total length L1 + L2 of the cutting tool 1 measured between the first end T of the cutting tool 1 and the second end 1” of the cutting tool 1 may be within the range of 1 - 10 meters or may be within the range of 1.6 - 9 meters. According to the illustrated embodiments, the length L3 of the pole 12, measured in a direction coinciding with the direction of elongation de thereof, is approximately 67 % of the length L1 of the body portion 2 measured from a first end T of the cutting tool 1 to the pivot axis Pa. According to further embodiments, the length L3 of the pole 12, measured in a direction coinciding with the direction of elongation de thereof, may be within the range of 20% - 99%, or may be within the range of 47% - 87%, of the length L1 of the body portion 2 measured from a first end T of the cutting tool 1 to the pivot axis Pa. Moreover, according to some embodiments, the cutting tool 1 may have a variable total length L1 + L2 for example by comprising a pole 12 having variable length L3.

As understood from the above, the length L1 of the body portion 2 is measured in a direction coinciding with the direction of elongation de of the body portion 2. Likewise, the length L3 of the pole 12 is measured in a direction coinciding with the direction of elongation de of the pole 12. Moreover, the total length L1 + L2 of the cutting tool 1 , measured between the first end T of the cutting tool 1 and the second end 1” of the cutting tool 1 , is also measured in a direction coinciding with the direction of elongation de of the body portion 2. Furthermore, the total length L1 + L2 of the cutting tool 1 is measured when the tool portion 4 is in the first pivot position relative to the body portion 2, illustrated in Fig. 1 and Fig. 2.

In the following a certain type of advantageous cutting procedure is explained. Below, simultaneous reference is made to Fig. 1 - Fig. 3a, if not indicated otherwise. As understood from the herein described, the cutting tool 1 can be used to cut objects at considerable distances from a ground surface without having to use a ladder, a stool, or the like for reaching the object. With reference to Fig. 3a, the object 30 illustrated can be said to be the cross section of a branch of a tree located at a considerable distance from a ground surface. In Fig. 3a a local gravity vector gv is indicated. The local gravity vector gv points towards a ground surface on which a user may stand.

The user may initiate the cutting procedure by placing the tool portion 4 against the object 30 as is illustrated in Fig. 2, i.e. with the tool portion 4 in the first pivot position and such that the object 30 is positioned in abutting contact with the cutting member 3 and in abutting contact with the first abutment 10. Then, the user may apply a force onto the body portion 2 such that a torque is obtained around the pivot axis Pa to pivot the tool portion 4 relative to the body portion 2 to the second pivot position illustrated in Fig. 3a. Please note that the cutting tool 1 is illustrated from different sides in Fig. 2 and Fig. 3a. As can be seen in Fig. 3a, in this example, the object 30 is located above the cutting member 3 seen relative the local gravity vector gv when the tool portion 4 has been pivoted to the second pivot position.

Thus, the user may pivot the tool portion 4 relative to the cutting member 3 such that the object 30 is located above the cutting member 3 and such that the cutting member 3 is abutting against an underside of the object 30. Then, the user may initiate cutting. According to the illustrated embodiments, the user may initiate cutting by simultaneously pressing the safety button 16 and the power control actuator 18 at the handle 6 of the cutting tool 1 illustrated in Fig. 1.

As an alternative, the user may initiate cutting when the tool portion 4 is in the first pivot position illustrated in Fig. 2 and may operate the cutting member 3 while pivoting the tool portion 4 from the first pivot position illustrated in Fig. 2 towards the second pivot position illustrated in Fig. 3a. In either case, the user will perform a so called undercut in which the underside of the object 30, i.e. the side of the object 30 facing the ground surface, is cut prior to an upper side of the object 30. The upper side of the object 30 is facing away from the ground surface. The user may operate the cutting member 3 during a certain time such that the object 30 is partially cut from the underside thereof. Then the user may pivot the tool portion 4 back towards the first pivot position.

Fig. 3b illustrates the second side the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1 - Fig. 3a in which the tool portion 4 has been pivoted to the first pivot position relative to the body portion 2. The user may operate the cutting member 3 during the pivoting from the second pivot position illustrated in Fig. 3a towards the first pivot position illustrated in Fig. 3b. As an alternative, the user may cancel operation of the cutting member 3 upon pivoting the tool portion 4 from the second pivot position illustrated in Fig. 3a towards the first pivot position illustrated in Fig. 3b. However, by operating the cutting member 3 during the pivoting, a cleaner cutting result can be obtained, as is explained in the following.

Fig. 3c illustrates the second side the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1 - Fig. 3b in which the tool portion 4 has been pivoted to a third pivot position relative to the body portion 2. As seen in Fig. 3c, the object 30 is located below the cutting member 3 seen relative the local gravity vector gv when the tool portion 4 is in the third pivot position.

Thus, the user may pivot the tool portion 4 from the first pivot position illustrated in Fig. 3b towards the third pivot position illustrated in Fig. 3c in which the object 30 is located below the cutting member 3 seen relative the local gravity vector gv. Thus, in this position, the cutting member 3 will abut against the upper side of the object 30 and will thus cut the upper side of the object 30 during operation. In this manner, the user can perform a so called overcut in which the upper side of the object 30 is cut. The user may operate the cutting member 3 until the object 30, i.e. the branch in the above example, is separated. Due to the previous undercut of the underside of the object 30, the object 30 can be separated in a clean manner with a low risk of so called splitting.

Moreover, by continuously operating the cutting member 3 in the pivoting movement from the second pivoting position illustrated in Fig. 3a, past the first pivoting position illustrated in Fig. 3b to the third pivoting position illustrated in Fig. 3c, the object 30 is cut in a planar cutting plane which provides a cleaner cut of the object 30. This is because the cutting member 3 will follow the groove formed by cutting during the pivoting movement of the tool portion 4 between the different pivoting positions.

According to the illustrated embodiments, the angle between the first pivoting position and the second pivoting position is approximately 90 degrees. Moreover, the angle between the first pivoting position and the third pivoting position is also approximately 90 degrees. Thus, according to the illustrated embodiments, the angle between the second pivot position and the third pivot position is approximately 180 degrees. According to the illustrated embodiments, the resilient member 13 is configured to prevent pivoting of the tool portion 4 past the second and third pivoting positions. In other words, according to the illustrated embodiments, the tool portion 4 can be pivoted 180 degrees relative to the body portion 2 around the pivot axis Pa. According to further embodiments, the cutting tool 1 may comprise another type of arrangement for limiting a pivoting movement of the tool portion 4 relative to the body portion 2, such as an arrangement arranged inside the housing 4’ of the tool portion 4 of the cutting tool 1. Moreover, the cutting tool 1 may comprise an arrangement configured to limit the pivoting movement of the tool portion 4 relative to the body portion 2 to another angle than 180 degrees, such as an angle within the range of 110 - 340 degrees, or an angle within the range of 160 - 240 degrees.

The above mentioned angles of the tool portion 4 relative to the body portion 2 may be measured between the reciprocating axis Ra of the cutting member 3 and the direction of elongation de of the body portion 2 of the cutting tool 1. Likewise, the above mentioned angles between the first, second, and/or third pivoting positions may be measured between the reciprocating axis Ra of the cutting member 3 and the direction of elongation de of the body portion 2 obtained in the respective pivoting position. Even though the body portion 2 is illustrated as being parallel to the local gravity vector gv in Fig. 3a - Fig. 3c, the design of the cutting tool 1 according to the illustrated embodiments allows a user to cut objects 30 at considerable heights from a ground surface without having to stand under the object 30 being cut.

As is indicated in Fig. 2, the cutting member 3 comprises a first cutting edge 31 arranged at a first side s1 of the cutting member 3 seen relative to the reciprocating axis Ra, wherein the first cutting edge 31 faces the first abutment surface 10’ of the first abutment 10. Moreover, according to the illustrated embodiments, the cutting member 3 comprises a second cutting edge 32 arranged at a second side s2 of the cutting member 3 seen relative to the reciprocating axis Ra. The second side s2 of the cutting member 3 is opposite to the first side s1 of the cutting member 3 seen relative to the reciprocating axis Ra of the cutting member 3. Furthermore, according to the illustrated embodiments, the cutting tool 1 comprises a second abutment 20 having a second abutment surface 20’. The second abutment surface 20’ is configured to abut against an object during cutting of the object with the second cutting edge 32 of the cutting member 3.

According to the illustrated embodiments, the second abutment 20 has an identical but mirrored design as the first abutment 20. Thus, according to the illustrated embodiments, the second abutment 20 has the same shape and size as the first abutment 10 and the first and second abutments 10, 20 together form a V-shape. The second abutment 20 may be used together with the second cutting edge 32 in the above described cutting procedure in which an undercut is performed prior to an overcut so as to provide a clean cut with reduced the risk of splitting.

Moreover, the design of the illustrated embodiments where the first and second abutments 10, 20 together form a V-shape provides further advantages. With reference to Fig. 3c, when the overcut has been made and the object 30 is separating from a remaining part of the object, the tool portion 4 can fall such that the second abutment 20 is abutting against the remaining part of the object. Thus, due to the V-shape formed by the first and second abutments 10, 20, the remaining part of an object being cut may fixate the tool portion 4 and may prevent a drop of the tool portion 4 towards a ground surface when a cut is finished. In this manner, a safer and more controlled cutting procedure can be obtained. As is indicated in Fig. 2, the cutting member 3 comprises a first end 3’ and a second end 3”. The cutting member 3 is attached to the tool portion 4 via the first end 3’ and the second end 3” is a free end. The power source 5 of the cutting tool 1 is thus operably connected to the first end 3’ of the cutting member 3 and is configured to reciprocate the cutting member 3 by reciprocating the first end 3’ of the cutting member 3. The cutting member 3 of the illustrated embodiments resembles a saw blade of a jigsaw. Due to the features of the cutting member 3, the cutting member 3 can be provided in a cost efficient manner. Moreover, a lightweight cutting member 3 can be provided. In addition, in contrast to other types of cutting units, such as a chains saw unit, the cutting member 3 does not need a lubrication system lubricating the cutting member 3 which also saves costs and weight of the cutting tool 1. Furthermore, in contrast to other types of cutting units, such as a chains saw unit, the cutting member 3 has conditions for performing a clean and smooth cut while consuming a low amount of energy. As a further result thereof, the tool portion 4 of the cutting tool 1 can be made to have a low weight. In addition, a small sized and low weight power source 5 can be used for powering the cutting member 3. Thus, as a further result of these features, a cutting tool 1 is provided having conditions for having a low weight. The cutting member 3, as referred to herein, may also be referred to as a “saw blade”, “a jig saw blade”, or the like.

As indicated in Fig. 2, the cutting member 3 is configured to move in a first and a second direction d1, d2 upon reciprocation. The first direction d1 is pointing towards the tool portion 4 of the cutting tool 1 and the second direction d2 is pointing away from the tool portion 4 of the cutting tool 1. Obviously, the second direction d2 is opposite to the first direction d1. As can be seen in Fig. 2, the cutting member 3 comprises a number of teeth 33 each being angled to provide a greater cutting efficiency when the cutting member 3 is moving in the first direction d1 than when the cutting member 3 is moving in the second direction d2. This is obtained by the teeth 33 being angled in a direction towards the first direction d1.

The above referred to teeth 33 are teeth of the first cutting edge 31 of the cutting member 3. In other words, according to the illustrated embodiments, the teeth 33 are angled in a direction towards the first abutment surface 10’ of the first abutment 10. Due to these features, a greater force is applied onto an object 30 when the cutting member 3 is moving in the first direction d1 than when the cutting member 3 is moving in the second direction d2. Thereby, an object 30 being cut is more securely retained against the cutting member 3 and the first abutment 10. This is because the cutting action of the cutting member will pull the object 30 in a direction against the first abutment 10. As a further result thereof, the cutting tool 1 can be used in a more ergonomic and safe manner. In Fig. 2, a number of teeth 33’ of the second cutting edge 32 are indicated. According to the illustrated embodiments, the teeth 33’ of the second cutting edge 32 is smaller in size than the teeth 33 of the first cutting edge 31. However, also the teeth 33’ of the second cutting edge 32 may provide a greater cutting efficiency when the cutting member 3 is moving in a first direction d1 than when the cutting member 3 is moving in a second direction d2. Due to the different size, a more versatile cutting tool 1 is provided allowing a user to select side s1 s2 and cutting edge 31 , 32 of the cutting member 3 depending on an object 30 being cut. However, according to further embodiments, the first and second cutting edges 31, 32 of the cutting member 3 may comprise teeth 33, 33’ having the same size and shape.

As is illustrated in Fig. 2, according to the illustrated embodiments, the cutting tool 1 comprises locking assembly 15. The locking assembly 15 transferrable between a locked state, in which the locking assembly 15 locks the tool portion 4 from pivoting about the pivot axis Pa, and an unlocked state, in which the locking assembly 15 allows the tool portion 4 to pivot about the pivot axis Pa. In Fig. 2, a knob 45 can be seen. As is further explained herein, the knob 45 is operably connected to the locking assembly 15 for transferring the locking assembly 15 between the locked and unlocked states.

Fig. 4 illustrates a third side the handheld cutting tool 1 according to the embodiments illustrated in Fig. 1 - Fig. 3c. In Fig. 4, the handheld cutting tool 1 is illustrated at an angle in which the pivot axis Pa between the tool portion 4 and the body portion 2 is perpendicular to the viewing direction of Fig. 4 and in which the cutting plane Pc of the cutting member 3 is parallel to the viewing direction. Moreover, in Fig. 4, the tool portion 4 is illustrated in the first pivot position relative to the body portion 2 referred to above.

Furthermore, as explained above, and as can be seen in Fig. 4, according to the illustrated embodiments, the angle a2 between the pivot axis Pa and the cutting plane Pc is 90 degrees. According to further embodiments, the angle a2 between the pivot axis Pa and the cutting plane Pc may be within the range of 60 - 120 degrees or may be within the range of 80 - 100 degrees. Thereby, a handheld cutting tool 1 is provided facilitating cutting and allowing a user perform overcuts and undercuts of objects at considerable distances in a simple, safe, and convenient manner.

In Fig. 4, a first and a second lock member 51, 52 of the locking assembly 15 are schematically illustrated. One of the first and second lock members 51, 52 is connected to the tool portion 4 and the other of the first and second lock members 51, 52 is connected to the body portion 2. Moreover, the knob 45 is operably connected to at least one of the first and second lock members 51, 52 such that turning of the knob 45 in a first rotation direction increases a distance between the first and second lock members 51, 52 and turning of the knob 45 in a second rotation direction reduces the distance between the first and second lock members 51, 52. In this manner, a user can transfer the locking assembly 15 to the unlocked state by turning the knob 45 in the first rotation direction and can transfer the locking assembly 15 to the locked state by turning the knob 45 in the second rotation direction. Thereby, a more versatile cutting tool 1 is provided allowing a user to lock the tool portion 4 from pivoting relative to the body portion 2 when performing some cutting tasks and to unlock the tool portion 4 to allow pivoting thereof relative to the body portion 2 when performing some other cutting tasks. As understood from the above, the locking assembly 15 according to the illustrated embodiments is a mechanical locking assembly and the locking assembly 15 is moveable between the locked and unlocked state. According to further embodiments, the locking assembly 15 may have a different design and may comprise another type of actuator than a knob 45 for transferring the locking assembly 15 between the locked and unlocked states.

Fig. 5 schematically illustrates an enlarged view of a tool portion 4 of a handheld cutting tool

1 according to some further embodiments. Moreover, in Fig. 5, a section of the body portion

2 of the handheld cutting tool 1 can be seen. In Fig. 5, the cutting tool 1 is illustrated from a first side and the tool portion 4 is illustrated in the first pivot position relative to the body portion 2 of the cutting tool 1 referred to above. The handheld cutting tool 1 according to the embodiments illustrated in Fig. 5 comprises the same features, functions, and advantages as the handheld cutting tool 1 according to the embodiments explained with reference to Fig. 1 - Fig. 4, with some differences explained below.

According to the embodiments illustrated in Fig. 5, the second abutment 20 has a different shape and a different size than the first abutment 10 of the cutting tool 1. In more detail, according to these embodiments, the second abutment 20 is considerable smaller in size than the first abutment 10. Moreover, the second abutment 20 comprises a second abutment surface 20’ having a surface normal N2 being substantially parallel to the reciprocating axis Ra of the cutting member 3. According to further embodiments, the second abutment 20 may be arranged such that the angle between the surface normal N2 of the second abutment surface 20’ and the reciprocating axis Ra of the cutting member 3 is less than 20 degrees or less than 10 degrees.

Since the second abutment 20 has a different shape and a different size than the first abutment 10, a more versatile handheld cutting tool 1 is provided allowing the user to use the first cutting edge 31 of the cutting member 3 when performing some cutting tasks and to use the second cutting edge 32 of the cutting member when performing some other cutting tasks. As an example, the user may use the first cutting edge 31 of the cutting tool 1 when performing an undercut and an overcut in the manner described with reference to Fig. 1 - Fig. 3c above. As another example, the user may use the second cutting edge 32 when wanting to reach certain objects or when wanting to cut an object having a certain diameter.

The wording “substantially parallel to”, as used herein, may encompass that the angle between the objects referred to is less than 10 degrees, or is less than 7 degrees.

It is to be understood that the foregoing is illustrative of various example embodiments and that the invention is defined only by the appended independent claims. A person skilled in the art will realize that the example embodiments may be modified, and that different features of the example embodiments may be combined to create embodiments other than those described herein, without departing from the scope of the present invention, as defined by the appended independent claims.

As used herein, the term "comprising" or "comprises" is open-ended, and includes one or more stated features, elements, steps, components, or functions but does not preclude the presence or addition of one or more other features, elements, steps, components, functions, or groups thereof.
