Description

1 101207

The present invention relates to a method and apparatus for splitting trees and, more particularly, for splitting relatively short pieces of wood into smaller pieces.

Trees burned in the household, such as firewood, have traditionally been chopped using a suitable substrate, such as a raised piece of log and an ax.

10 However, an ax is a rather cumbersome tool, especially in unfamiliar hands, and for this reason accidents leading to various types of damage are twinkling when ordinary trees are picked with an ax.

In order to avoid the above risk, other types of splitting devices have been developed,. 15 for example, a rod-like device, now called a wedge ax and ';', by means of which the splitting takes place by moving a linearly moving impact rod.

The risk of accidents has been decisively reduced.

Cleavage with a wedge ax takes place in such a way that at the lower end of the rod - like device • ·. The blade 20 is placed in the desired position at the end of the raised piece of wood, after which the relatively heavy impact bar is raised to the up position and dropped to cause the blade to sink into the wood and the wood to crack. Impact bar: ‘·: usually accelerated by hand.

«· · • · ·. the head is sawn obliquely or the base surface is oblique. Cutting with both an ax and a percussion rod-type tool always involves moving the desired pieces of wood to a stack or other location, which is almost always a manual collection job.

The object of the present invention is to provide a method and an apparatus by means of which the above-mentioned drawbacks are solved and an easy, safe and fast felling of trees is achieved. A further object is at its best to provide a method and a device which also make it possible to move chopped trees easily and safely from one place to another and possibly to bundle them.

The above and other advantages and advantages of the present invention are provided as set forth in the appended claims.

The invention will now be described in more detail with reference to the accompanying drawings, in which various modifications of the device according to the invention are shown. The method will become apparent from the following description. Thus, in the drawings:

In addition, it is noted that the dimensions or other properties in the figures do not necessarily correspond to what is done in practice.

The method and apparatus of the invention will now be described with reference to the drawings, which show various embodiments of the apparatus. The course of the method becomes clear in connection with the description of the device.

Thus, Figure 1 shows an embodiment of the invention seen from two directions. Thus, the device 1 consists of a perimeter 2, inside which the trees 3 to be logged are assembled so that the inside of the perimeter 2 is loosely filled with them, whereby, if desired, the expanding parts of the trees have enough space to prevent their cracking. The arrangement of the trees can be done with the perimeter 2 on its side on the base or when it is in a vertical position. When the perimeter is filled, if desired, a suitable tightening loop 4 or more is used to place the trees as close to each other as possible.

15 The perimeter is then turned to the side on a sturdy base and the splitting of the trees with an impact bar type means can begin. When the splitting work is completed, the loops 4 are removed and the chips can be moved from inside the circumference to the stack, for example, or alternatively the circumference 2 is moved again to the vertical position and by gripping the handle ': it can easily be carried directly next to the stack.

If necessary, the device described above has supports 6, by means of which the device remains firmly in place when in an upright position.

«· ·» ··· Γ “: 25 In certain situations there is a clear advantage that the perimeter 2 has to be opened. For example. · · ·. trees are easy to tighten inside the perimeter if the perimeter circuit is expandable and then • ·: ·. ·. -down. Figures 2a-2b show a side view based on this and a top view, respectively. The circumference now consists, unlike the plate-like circumference described above, of rod-like parts divided into two halves 22 and 22 '. The halves are articulated to each other at 24. The handle 25 is mounted so that its first half is articulated to the first half at 26 and the second half at point 26 'to the second half 22', respectively. For example, the handle 25 has a rotatable portion 27, the rotation of which 4 101207 in one direction causes the handle portion to elongate and the rotation in the opposite direction to shorten it. Thus, shortening tends to open halves 22 and 22 'and lengthening tends to close it. In this way, the trees can be flattened into the circumference relatively firmly and the splitting with the impact bar 5 is performed with the tightened circumference in a horizontal position.

Figures 3a-3d show a third embodiment of a device according to the invention. The figure shows the model that can be opened and closed in the style described above. The circumference consists of circumferential halves 32, 32 'articulated around a point 35. The locking device 10 37, which may be of any suitable type, holds the halves together if desired.

A special feature of this model is that the legs 36 are attached, in particular, to the cross-sections 38, 38 'made of pipe, which when the device is turned to the side of the trees; 15 for splitting, correspond to the base and that the handle 34 is also located at the end of the loop-like part 39, whereby the outermost point of the loop 39 acts as a third support point. Also in this embodiment, suitable ties can be used to hold the trees firmly in place, as shown in Figure 3b.

Figures 4a-4b show another embodiment of a device according to the invention. This device differs from the previous embodiments in that it has two circumferences 42, 42 'and a connecting rod 43 which is preferably fixedly attached to the upper circumference 42 and the lower circumference of the lateral device "*: · it is in a hole 45 from which it can be easily lifted Rotation of the rod 43 about its axis is preferably prevented, for example by shaping the lower end of the rod and the corresponding hole at an angle.

• · · • · »• · ·« *

The loading of the device described above with trees takes place when both perimeters are in place and attached to each other via the rod 43. After loading 30, a tying loop 46 is preferably used to tighten the trees in place, as mentioned above in connection with other applications. The trees are halved using an impact bar, after which the halo bundle tied by the same or different loop is left on the bandage and the lower perimeter 42 'by lifting the upper perimeter 5 101207 42 and the bar 43 out of place. The handles 44, 44 'facilitate lifting. The circumference 42 and the rod 43 do rise slightly, as the relatively thin and smooth rod 43 causes quite a bit of resistance, even if the trees compress it to some extent. In addition, by using the loop-like seat 5 47 for the rod shown in Fig. 4b, space is reserved for the rod at the same time.

Fig. 4c shows an embodiment in which the mutual arrangement of the two perimeters 42, 42 'is different from the previous one. Thus, the perimeter 42 is articulated to pivot about the joint 48 so that at the stage when it is desired to remove the desired bundle of wood 10 or tie it with a bandage 46, the perimeter 42 can be pivoted out of the way as shown. The connecting arm 43 is preferably fixedly attached to the lower circumference 42 'and is located attached to the outside of the circumference 42'.

Figures 5a-5c show one way in which the top of the desired trees is released to remove or tie the trees. The circumferences 52 and 52 'are connected to each other by means of "legs" 55, 55' and 54, the latter comprising a handle part for moving and carrying the device. Hinges 56 are mounted on the legs, around which the legs are folded, whereby the upper circumference 52 descends against the folding. releasing the tops of the trees for the desired measures. The series of figures 5a-5c is probably self-explanatory in other respects.

Figures 6a-6b schematically show still some features of the invention. The figures show a perimeter 62 which is now placed on a base plate 63 having a handle 66 or the like at one edge and further having projections 65, the perimeter 62 being placed on the projections 65. The perimeter itself may, as shown, have a handle 64 to facilitate handling. Trees 67 can now be stacked and • logged into it. Thereafter, the perimeter 62 can be lowered substantially against the surface of the board by any means, as illustrated in Figure 6b, and the trees are now easy to remove or tie.

A suitable system can be built to calculate the perimeter. It is very convenient to use a telescopic system in a certain way, in which case the device can be locked in a suitable simple manner in the upper position and released from it for moving to the lower position.

The device according to the invention needs a suitable substrate for splitting. An exemplary substrate may be a substrate made of a sheet-like material, for example molded plywood, placed on a solid base. The slab-like substrate can be on concrete slabs, for example. As a detail that facilitates the work, the plate-like base can be made much larger than the perimeter and one of its edges facing the worker can be provided with, for example, a handle-type gripping means, whereby, after splitting, the plate is turned vertically easy to carry away by grasping its handle.

The base may also be provided with suitable means to facilitate the retention of the perimeter placed on it. For example, these means may be recesses in the plate 15. The intention is that when the device is turned sideways on the plate, the parts on which the device rests against the base press into the recesses and thus hold the device in place. Other types of "stoppers" are also easy to mount on the disc to keep the device in the desired position.

The preferred manufacturing material of the structure according to the invention is a metal plate, a metal rod or a metal pipe or a combination thereof. However, for example, many types of plastic are durable enough for the intended use, which is why parts of the devices or complete devices can be made of plastic-based materials. At least as part of the device, it is possible to use parts made of 25 wood. The choice of material is not critical.

The invention can be modified in many ways without departing from the scope of the invention. Thus, for example, the device according to the invention can be used to carry trees directly to a wood burning site, such as next to a fireplace or the like. For such use, in the vertical position of the circumference, a fixed or removable plate-like part, in particular a circumferential part, can be placed on the lower parts, which prevents debris from shrinking onto the target.

In the device according to the invention, it is possible to use as many different means as possible to achieve opening and closing. Dozens of such hinge and lock devices are known in various fields of technology.

5 It is clear that the shape of the perimeter is a very trivial matter. The perimeter may be constructed to be round or nearly circular as described above, but there is nothing to prevent the construction of a hexagonal, rectangular or triangular perimeter for the purpose indicated. If desired, a base can be added to the perimeter, which in certain situations can also act as a reinforcement for the splitting itself, in which case the actual base 10 does not have to be so strong.

The perimeter of the device according to the invention can be provided, in a side-folded position at its upper edge, with means, for example hook-type means, on which a reticulated "sock" or a bag can be hung inside the perimeter. This results in a neat package that is inside the coating, reticulated or otherwise, and thus easy to transport and store.
