Description

An improved tool carrier, preferably a chainsaw, and a work machine, preferably a winch, with said carrier

The field of technology

The invention belongs to the field of forestry winches, more precisely to the field of structural details of forestry winches or other machines where a place to store a chainsaw is desirable. The present invention relates to an improved tool carrier, preferably a chainsaw, and a working machine, preferably a winch, with said carrier.

Background of the Invention and Technical Problem

When working in the forest, there is often a need for a chainsaw or other tool, which is why many winches and similar work machines have a space or carrier for storing and transporting tools such as a chainsaw. In known solutions, the chainsaw carrier is fixedly mounted on the inside of the protective net, whereby the carrier is placed at an angle. Disadvantages of a carrier mounted in this way are:

- poor protection of the chainsaw during transport, so that the saw is damaged, as a result of which its operation is weakened or even impossible, — the possibility of the chainsaw breaking down during transport, and

- difficult extraction of the chainsaw from the carrier.

Alternatively, the position of the chainsaw support could be parallel to the ground, as described in document SI22801, which would significantly improve the protection of the chainsaw and the possibility of the chainsaw falling out of the support, but such a position in the case of a different construction than that described in SI22801 would significantly made it difficult to pull the chainsaw out of the holder.

Therefore, the technical problem that is solved by the present invention is the structural solution of the support, which will have better protection of the chainsaw and easy access to the saw when it is needed when working in the forest. The solution should also be suitable for other machines that are used at work and for which the presence of a tool holder such as a chainsaw is desirable.

State of the art

Patent SI22801 describes a winch with a device that enables the reliable and safe attachment of forestry tools to the forestry winch, namely to the area of the safety guard or netting of the forestry winch. Said arrangement comprises a first part, on which there is at least an approximately vertical slot, which is adapted to receive a chainsaw blade including a link chain with cutting edges, as well as at least one second part, which is spaced from the first part, having the second part is an approximately horizontal support surface, which is adapted for laying the chainsaw cover and in the vicinity of which at least one fastening means is provided for attaching the chainsaw cover to the mentioned second part.

This solution describes an approximately horizontal position of the chainsaw during transport, which differs from the present invention.

Description of the solution to the technical problem

The technical problem is solved as presented in the independent claim, with preferred solutions to the technical problem being presented in the dependent claims. The essence of an improved tool carrier, preferably a chainsaw, for installation on a working machine is that it consists of:

- the first (supporting) plate, which is adapted for fixed installation on the working machine, the second plate, which is convex in the central part and adapted for contact with the first plate,

- the third and fourth plates, which are placed on the second plate in such a way that there is a space between them that is adapted to receive a chainsaw blade or some other tool,

- the pivot connecting the first and the convex part of the second plate in such a way that the second plate and all the plates attached to it can rotate around the pivot, and

- a suitable locking mechanism that ensures rotation lock.

The rotary attachment via the first plate and the second plate is therefore adapted for installation on the working machine, and enables rotation about the pivot, so that the carrier has a transport position and a position for extracting the tool, whereby rotation about the pivot can be disabled by a locking mechanism. The angle between the two mentioned positions is between 45° and 115°, preferably between 60 and 100°, most preferably around 90°. The rotation is preferably limited to 90° relative to the transport position for safety reasons. The appropriate angle is determined by suitable motion limiters or by any other means such as curved sheet metal or similar solutions known to a person skilled in the art. For example, for this purpose, the first support plate has a cut-out in the lower part, in which the screw connecting the second, third and fourth plates is caught when reaching the final position, thus preventing further rotation of the support. Preferably, the carrier plate has an additional, second cut-out in the upper part, namely on the same side as the cut-out in the lower part, wherein said second cut-out in the upper part is intended to receive the screw connecting the second, third and fourth plates when it reaches the second extreme position of the carrier.

Said plates are preferably rectangular or square in shape, they can completely cover the blade of a chainsaw or any other tool that is inserted into the holder, with the appropriate distance between the third and fourth plates being ensured by spacers, bushings, nuts or similar elements. The second, third and fourth plates can be connected to each other by known non-separable connections such as welding or by known separable connections such as bolts and nuts. The material for said support is any suitable material known to a person skilled in the art, preferably metal. The material of the carrier plate and any of the remaining plates may be the same or different, whereby for example the third and fourth plates may be made of wood or plastic. In addition, the outermost plate, usually the fourth plate, can be equipped with an additional hook or attachment for the handle of an ax or any other tool, which does not need its own holder or needs to be stored elsewhere.

The pivot can be made in any suitable way, but preferably a screw is used, which is installed through a hole in the body of the working machine, through a hole in the central part of the first plate and through a hole in the central part of the second plate. It can be fixed with a nut, which is then located between the second and third plate.

The chainsaw holder is locked in the desired position with a locking mechanism or guard, which can be of any kind known in the field of technology. A preferred embodiment of the locking mechanism is a locking pin as is known in the art and is commercially available. If it is desired to move the support to the position for use or to extract the tool, it is necessary to first pull out the locking pin, then rotate the support to the desired position, which will be suitable depending on the height of the support on the machine and the height of the user, after which the locking pin is reinserted to the use position is locked. Alternatively, after pulling out the tool or the chainsaw, the carrier can be returned to the transport position, which is less desirable, because after finishing using the tool, the user must first unlock the position, move the carrier and only then return the tool to the carrier and, after releasing the lock, return the carrier to the transport position. position.

The first and second plates preferably have a lug (i.e. projecting portion) on one side into which a locking mechanism can be fitted so that the two plates are further connected to each other and the other cannot rotate about the pivot. However, if the locking mechanism is released, the first and second plates are no longer connected, and the second plate can be rotated around the pivot to the desired position, in which it can optionally be locked with the same locking mechanism.

The working machine is preferably a forestry winch, and the tool is a chainsaw, which is most often used when working in the forest.

Furthermore, the special feature of the improved support is that it is not mounted on the protective net, so that the handle would extend outside the area of the winch, but the support is located on the frame itself or the housing of the work machine or forestry winch, so that the entire chainsaw is hidden in the transport position.

The holder described better protects the tool and at the same time allows easy access to the tool when it is needed at work.

An improved chainsaw mount and winch with said mount will be described in more detail below with the help of figures showing:

Drawing of the carrier according to the implementation example

Figure 1 shows a winch 1 with a known support 2 of a chainsaw 3, where the frame of the support 2 is placed immediately under the protective net 1a, into which the saw blade 3 is inserted, while its handle 3a freely protrudes outside the winch 1, due to which it can, in the event of shocks and vibrations can cause damage or even the saw 3 falling out of the holder 2.

Figures 2 and 3 show the winch 1 with an improved support 12 of the chainsaw 3 according to the invention, namely, Figure 2 shows the position of the support 12 during transport (transport position) when the chainsaw 3 is completely hidden behind the protective net 1a and the framework of the winch 1, which is optimal for protecting the chainsaw 3. It is also impossible for the chainsaw 3 to fall out of the chainsaw 3 holder 12 during transport. Figure 3 shows the position for extracting the chainsaw 3. Such a position enables easy and user-friendly extraction of the chainsaw 3 from the support 12, which is especially common with larger winches, due to the height of the placement of the support 12 of the chainsaw 3. As can be seen from both pictures, it can bracket 12 is placed on one or the other side of the frame of the winch 1, the winch 1 can be equipped with two brackets 12, i.e. with one bracket 12 on each side. The shapes of the brackets can be the same or different, so that each can accommodate the same or different tools.

Figure 4 shows an exploded view of the support 12 according to a possible embodiment, which is presented as a whole in Figure 5. The support 12 consists of the following components: - the first plate 12a, which is adapted for fixed installation on the working machine, the second plate 12b, which is convex in the central part 12b and adapted for contact with the first plate 12a,

- the third plate 12c and the fourth plate 12d, which are placed on the second plate 12b in such a way that there is a space between them that is adapted to receive the blade (blade) of a chainsaw or any other tool,

- pivot 12e, which connects the first plate 1a and the convex part 12b of the second plate 12b so that the second plate 12b and all plates 12c, 12d attached to it can rotate around the pivot 12e, and

- the locking pin 12f placed on the ear 12a' of the first plate 12a, which ensures the rotation lock.

The second, third and fourth plates 12b, 12c, 12d) are connected to each other by screws 12g, and the corresponding distance between the third and fourth plates 12c, 12d is provided by nuts 12h. The first and second plates 12a, 12b have a lug (i.e. a protruding part) 12a', 12b' on one side, in which a locking pin 12f is placed, so that the two plates are further connected to each other and the second plate 12b cannot rotate around the pivot 12e . If the locking pin 12f is pulled out or released, the first and second plates 12a, 12b are no longer connected and the second plate 12b together with the third and fourth plates 12c, 12d can be rotated around the pivot 12e to the desired position for extracting the chainsaw or other tool . Rotation around the pivot 12e enables an angle between the two mentioned positions (transport and extraction position) between 60 and 100, optimally around 90°. As shown in figure 5, the rotation around the pivot 12e is limited for safety to an angle of 90° with respect to the transport position by means of a cut-out 12a in the lower part of the first support plate 12a, which is designed in such a way that the screw is caught in it when the end position is reached, thereby preventing further rotation of the support plate 12. The support plate 12a has an additional, second cut-out 12a' in the upper part, namely on the same side as the cut-out 12a in the lower part of the support plate 12a, wherein said second cut-out 12a' in the upper part is intended for receiving of the 12g screw connecting the second, third and fourth plates when it reaches the second extreme position of the bracket.

Within the scope of the invention as described herein and defined in the claims, other embodiments of the tool carrier may also be possible, which are clear to a person skilled in the art, which does not limit the essence of the invention as described herein and defined in the claims.
