う悲惨な事故の報告は後を断たない。(Prior Art) Safety standards regarding lumber are specified in detail by the Industrial Safety and Health Act. Regarding circular saws, strict standards are stipulated not only for the material strength of the circular saw itself, but also for the attached equipment that ensures the safety of workers when sawing lumber using a circular saw. Naturally, the circular saws and associated equipment that were being sold were supposed to be legal products that had cleared those regulations. However, despite this, there are still reports of tragic accidents in which workers accidentally drop their fingers while sawing.

関するものは特に規定がない。Among the provisions stipulated by the Industrial Safety and Health Act, regarding attached devices, there is a device for preventing the cutting of processed materials from collapsing. Only the safety standards to prevent it from being thrown up and the contact prevention device, i.e. the cover to prevent the circular saw from being left protruding on the workbench, are required for machining. There are no specific regulations regarding the safety of hands when pushing materials.

透視用窓に別り抜かれた構造とすることによって実現す
ることができる。The circular saw upper cover member 1 is formed in m-shape so that it can freely rotate above the circular saw S using the pivot portion 11 as a rotation fulcrum, as shown by the arrow in the side view of FIG. The state in which the contact member 2 is in contact with the workbench T is the lowest position, and other than the embodiments shown below, it may be formed by, for example, aluminum casting, press molding of a steel plate, or plastic molding. In order to ensure that the teeth, which are the machining and cutting parts of the circular saw stipulated by law, can be clearly seen during work, the top surface of the end opposite to the pivoting part 11 is divided into a viewing window of an appropriate size. This can be achieved by creating a simplified structure.

In addition to being formed through the batten members 5, 5, a special metal fitting may be prepared in place of the batten member 5.5, or the end of the circular saw upper cover member 1 may be adsorbed onto the upper end of the support plate 4 in advance. In the figure, 51 indicates a structure in which a batten member 5.5 is clamped to the upper end of the support plate 4. , shows a fixing fitting for fixing.
なお、丸鋸上方覆い部材1の中間部辺り、丸鋸Sの上方
適当範囲をカバーできる部分には、法規で規定されてい

れを受は入れ、枢着部11を回転軸として上方へ円滑に
持ち上けられていくような構造のものに形成される。The contact member 2 is in contact with the workbench T, as in the example shown in the side view of FIG. A side edge that remains at a predetermined height above the table T and does not obstruct the feeding of the workpiece W to be sawn into the direction of the circular saw S. In order to do this, the side edge shape must be arcuate at least on the side where the workpiece W is fed, so that when it comes into contact with the end of the workpiece W, it should be smooth. The structure is such that it can be inserted into the receiver and smoothly lifted upward using the pivot portion 11 as the rotation axis.

のものとして実現される。The descending angle adjusting member 6 is installed between the support plate 4 and the circular saw upper cover member 1 as necessary, and when the workpiece W is thick, the abutment member 2 is placed on the workbench T. If the type is in contact with the workpiece W, the angle change of the contact member 2 will be that large, which may cause trouble when feeding the workpiece W. It serves the function of stopping the lowest point of the member W and preventing it from descending below that point.
Place a wedge-shaped piece as appropriate on the wood member 5 and the circular saw 2-way cover member 1
As shown in the figure, the step-like notched members may be shifted and engaged as appropriate, so that the interval between the batten member 5 and the circular saw upper cover member 1 is adjusted to the workpiece to be sawn. It is realized as a W4 structure that can be adjusted to the optimal spacing according to the thickness of the W.

た木材加工用丸鋸の歯への接触予防装置である。(Example 1) In this example, unlike the basic structure exemplified above, the circular saw upper cover member 1 is arranged side by side and parallel to each other, as can be understood from the perspective view of FIG. It is formed from a pair of steel bars, and a scattering prevention plate 12 is attached between the steel bars located above the circular saw S, and the contact member 2 is also the same as the above-mentioned circular saw upper cover member 1. This is a contact prevention device for the teeth of a circular saw for wood processing, which consists of a pair of parallel arc-shaped steel rods supported by each J14 rod.

装置の例である。(Example 2) The following example uses a circular saw upper cover member 1 and an abutment member 2 whose appearance approximately matches the appearance formed by the skeleton formed using the steel rods described above. This is an example of a contact prevention device for the teeth of a circular saw for wood processing, both of which are made of a transparent flat plate material, such as a transparent plastic plate or a tempered glass plate.
透明素材を採用することにより、而によって形成されて
もその内部が透視でき、アルミニウム鋳物や鋼板等で形

。(Operation and Effect) The device for preventing contact with the teeth of a circular saw for wood processing according to the present invention having the above-described configuration is assembled above the circular saw S on the workbench T, and is used to normally cut the workpiece W to be sawn. Feed the saw into the circular saw in the S direction with both hands, as if you were sawing the wood. Then, the tip thread 1 of the workpiece W first hits the abutting member 2 of the device, or by continuing to push it as it is, the tip of the workpiece W hits the abutting member 2, which is formed in an arc shape. The abutting member 2 is pushed up naturally as it goes under along its outer edge, and finally the lowest point of the abutting member 2 is brought into contact with the surface of the workpiece W as shown by the two-point nod line in FIG. Proceed in the direction of circular saw S while letting it slide. Then, the tip of the workpiece W reaches the circular saw S and is sawn.
こうして製材が進行していく中、加工材Wの表面に押し
当てた先端側の手が、加工材Wを送り込むために加工材
Wと共に丸鋸S方向に移動していき、そのまま押し込ん
でいけば当然丸鋸Sに達してしまうため、これまでであ

向を遮るような形で存在することから、手の指は自然に
指移動停止案内部材3に絡まるような状態となって、そ
れ以上指が丸ili!S方向に近づくことを邪魔される
こととなる。While sawing progresses in this way, the hand on the tip side pressed against the surface of the workpiece W moves in the direction of the circular saw S together with the workpiece W in order to feed the workpiece W, and if the hand continues to push the workpiece W into the direction of the circular saw S, Naturally, it would reach the circular saw S, so in the past, the worker himself would have to look at the teeth of the circular saw S and put his hand on the circular saw S.
However, with this device, the lowest point of the contact member 2 was in contact with the surface of the workpiece W in front of the circular saw S. , the finger movement stop guide member 3 is arranged at the contact part, that is, the lowest point part of the abutment member 2, and exists in a shape that blocks the feeding direction of the workpiece W, so that the fingers of the hand are not moved naturally. My fingers became entangled with the finger movement stop guide member 3, and my fingers became curly! This means that they will be obstructed from approaching the S direction.
そこで、作業者は、先端側の手を指移動停止案内部材3
に絡ませたままの状態で加工材Wを押さえながら滑らせ
、残る後方のもう一方の手で加工材Wを送り込んでいく
ようにして作業を完了する。Therefore, the operator moves his/her hand on the distal end side to the finger movement stop guide member 3.
The work is completed by sliding the workpiece W while holding it while still entangled with the workpiece W, and feeding the workpiece W with the other hand remaining at the rear.
したがって、従前までのように、何かの拍子につい注意
が散漫となって先端側の手を加工材Wと共に移動してし
まって丸鋸SのViIまで達しさせてしまい、不測の事
態に至らせてしまうということが確実に防止されるしの
となる。Therefore, as before, my attention got distracted for some reason and my hand on the tip side moved along with the workpiece W, causing it to reach ViI of the circular saw S, leading to an unexpected situation. This will ensure that this is not the case.

証されるという利点を有するものである。In particular, in the circular saw in which the upper cover member 1 and the contact member 2 are formed into a skeleton shape using steel rods, in addition to being easy to manufacture, the view is almost obstructed. It is a knife that enables you to carry out work that is difficult to carry out, and can eliminate the discomfort during work to a large extent. This has the advantage of allowing work to be carried out in a stable condition, ensuring even safer lumber work.

を発揮できるものである。Furthermore, even if the circular saw upper cover member 1 and the abutment member 2 are made of a transparent material, they are more difficult to use than those made of other opaque aluminum materials, steel plates, etc.
It can also achieve substantially the same effect as the above in that it can be seen through.

ことか予想される。As mentioned above, the device for preventing contact with the teeth of a circular saw for wood processing according to the present invention is unprecedented in terms of safety, manufacturing, etc., as well as handling work. It has advantageous characteristics and makes it possible to carry out efficient and safe lumber work that was not possible with previous methods that simply cleared legal regulations and had little practical consideration. It is expected that this product will receive high praise from those involved in the lumber industry.
