BRIEF SUMMARY OF THE INVENTION
The object of the present invention to provide a saw bench, with which a large variety of material types to be cut can be sawn and for a user of the saw bench the sawing process is safe and trouble-free.
The above object is achieved by a saw bench comprising a first pair of legs; a second pair of legs; at least two cross members for material to be cut are arranged between the first pair of legs and the second pair of legs; a first abutting element and a second abutting element are provided with each cross member and being arranged at an angle with respect to each other; a kerf is defined between the cross members; and at least a first guide rail and/or at least a second guide rail for a sawing member is mounted on the saw bench in such a way that, during sawing of the material to be cut, the sawing member reaches through the kerf below a level of the material to be cut.
According to the invention each cross member comprises a first abutting element and a second abutting element is arranged at an angle with respect to each other. A kerf is defined between the cross members. In order to ease the sawing process, at least a first guide rail and/or at least a second guide rail for a sawing means is mounted on the saw bench in such a way that, during sawing of the material to be cut, the sawing means reaches through the kerf below a level of the material to be cut.
The first guide rail is mounted to the frame at the backside. For a safe cutting, a guide pin is attached to the sawing member, so that the sawing member is slidably guided in the first guide rail. The first guide rail is provides with a holding fork at which the sawing means can be parked after the sawing process. The second guide rail is mounted to the frame at the backside of a second abutting element. A guide pin which is connected to the sawing member, in which is slidably guided in the second guide rail. On the second guide rail, a holding fork is mounted, on which the sawing member is parked.
Furthermore, a rocking device can be mounted to the frame in a receptacle at a free end of the second abutting element. A guide pin is connected to the sawing member and is slidably guided in a guide channel of the rocking device. On the rocking device, a holding fork is provided at which the sawing member is parked.
At a free end of the first abutment element and/or at a free end of the second abutting element at least one take-up is provided in which the holding elements are pluggable for holding elements or the timber to be cut. Each holding element is provided at least one pin, which engages in a form-fitting manner in order to mount the holding element in the receptacle.
The legs of the first pair of legs and the legs of the second pair of legs are each rigidly connected together such that the legs of each pair of legs are arranged at an acute angle.
The two pairs of legs and the cross members for the pieces to be cut are rigidly fastened to a frame of the saw bench. The frame of the saw bench may be associated with four rigid base supports, which are not adjusted in height. The base supports have slides mounted at opposite ends, so that the saw bench can be moved easily. According to a further embodiment of the invention the four floor supports are height adjustable. This allows the equalizing on uneven ground.
At least one extension module is detachably connected to the frame of the saw bench. Depending on the type of the extension module two rigid, not height adjustable floor supports or two height adjustable floor supports are mounted.
To increase the comfort of use of the saw bench, a wheel can be attached to the saw bench. The wheel is adjustable in height by means of a mechanical crank. Similarly, two driving handles can be inserted into corresponding slots on the frame of both directions. The driving handles are parked in appropriate positions on the frame and do not disturb the working process when the saw bench is in use.
The first abutting element and the second abutting element have several securing elements for the material to be cut, so that any slipping of the material to be cut is avoided.
The basic idea of the inventive multi-functional saw bench is the expansion to several versions which have different working lengths. The model “beginner” measures 800 mm, the model “standard” measures 1000 mm and the model “professional” has a working length of 1300 mm. For example if firewood (maximum diameter 33 centimeters) or any other material which to be cut, the support has cross members that are welded on a sturdy frame made of square tube elements. The cross members have different widths and are separated kerfs (width about 10 centimeters). The user can saw the material to be cut with a motor chain saw or electrical saw vertically from above. The cut is directed to one of the kerfs. These kerfs are arranged so that the users saw the material to be cut completely through and the sawing member passes, due to the kerfs, substantially below the level of the on the cross members.
Thus, the wood or the material to be cut does not fall off the saw bench before or after the sawing process, on both sides of the support formed by the cross members, holding elements are provided, which are also made of a tube with rectangular form. These support elements are mounted to the framework of the saw bench. The support elements can also be arranged arbitrarily and can also be parked below the support surface in designated elements. So they always remain available on the saw bench, can be secured by bolts and do not get lost. The support elements are suitable not only for bundles of firewood, but also for the branches, round timber or boards. Also curved can be tamed with the inventive saw bench. Twist locks prevent a turn away especially of round wood at the time of sawing. Additionally, the cut wood remains on the saw bench as a package and can be removed from the saw bench as a whole.
So that the user does not have to cut freehand, the saw is used together with at least one guide rail on the frame of the saw bench. Thus, a tilting of the sawing member or a sawing into the cross members can be prevented. The guide rails are slightly inclined inwards, which facilitates the sawing process and supports the natural sawing motion. A guide pin, for example a chain cover nut of a chainsaw, provides the necessary guidance of the chain saw in the guide rail.
Another advantage is that the guide rails mark the respective cut at the position of the saw kerfs. The mounted or mountable guide rails, however, highlight the correct cutting position clear and unmistakable. For a better distinction all pluggable, i.e. removable parts on the saw bench are painted in the signal color orange. In addition, after each sawing, the saw can be suspended in a holder, which is connected downstream of the guide rail. The saw is then in a cleared position.
So that the saw bench can be easily moved, a chassis is provided, which consists of a wheel, which is adjustable in height by means of a mechanical crank. With the height adjustment of the wheel a ground clearance of up to 25 centimeters is be provided. The wheel can be attached at both sides of the saw bench. Also two handles can be attached in either driving direction and can be parked on the frame of the saw bench.
The length of the saw bench can be extended with extension modules. Each extension module can be docked bay at least three connectors to the saw bench to be extended. It is also possible that the saw bench is provided with four height-adjustable floor supports to compensate for uneven terrain. The sawing with a hacksaw, so with pure muscle power is also possible. The hacksaw can be guided by one of the guide rails during the cutting process.
According to a further embodiment the saw bench comprises a first pair of legs and a second pair of legs. At least two cross members for material to be cut are arranged between the first pair of legs and the second pair of legs. A first abutting element and a second abutting element are provided with each cross member and being arranged at an angle with respect to each other. A kerf is defined between the cross members. A rocking device for a sawing member is mounted to the second abutting element of the saw bench. The rocking device and a securing pin ensure a safe cutting process for motor, hydraulically or pneumatically driven sawing members. After cutting through the material remains on the saw bench and a slip off of the material is avoided. The securing pin is provided with the sawing member and is slidably guided in a guide channel of the rocking device. A holding fork is mounted to the rocking device in order to park the sawing member after the sawing process.
