JPH0512036U - Table saw cutting position pointer device - Google Patents

Abstract

(57) [Summary] [Purpose] The cutting position is adjusted simply by operating the pointer in the front-back direction in conjunction with the cutting operation. [Composition] A lower guard 1 rotatably connected to a bearing 14 and connected to an operating arm 17 via a link 18.
A pointer indicating the cutting position was provided at one end of No. 5. [Effect] By rotating the safety guard 4 up and down with the fulcrum shaft 5 as a fulcrum, the pointer provided at one end of the lower guard 15 linked to the safety guard 4 moves approximately horizontally. Therefore, the pointer above the work piece moves away from the work piece in conjunction with the cutting operation, and the position can be easily adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a pointer for indicating a cutting position of a table saw.

(Prior Art) Conventionally, there is no device for instructing the cutting position on the table saw, and since the position is confirmed by hitting the blade of the circular saw with the object to be cut, the safety guard 4 may be lowered or raised. The position had to be adjusted while performing a bouncing motion, and the rotation of the circular saw had to be stopped each time.

(Problems to be solved by the device) The technical problem of the present invention is to provide a pointer so that the cutting position can be easily adjusted even when the saw blade is rotating, and at the time of cutting work, the pointer does not interfere with the cutting. To move to.

(Means for Solving the Problem) In order to solve the above problems, the present invention allows the base end portion of the safety guard 4 to be vertically rotated on the hinge member 3 of the surface plate 1 for mounting and fixing the cut object. In addition, while holding the safety guard 4 in the upper movement position when the hand is released, the finger is held by the fulcrum shaft 5 with the spring 13 interposed therebetween, and the vicinity of the proximal end of the lower guard actuating arm 17 is set to the fulcrum described above. The lower guard 15 is rotatably rotatably supported by the spring 5 in a direction in which the lower guard 15 is rotatable about the shaft 5 and can shield the exposed portion 11b of the saw blade 11a by a spring 20, and is supported by the operating arm 17 via a link 18. The interlocked lower guard 15 is rotatably connected to the bearing 14 of the circular saw mounting drive shaft 9, and the lower guard 15 urges the operating arm 17 to rotate in such a direction as to shield the exposed portion 11b of the saw blade 11a. The spring 20 is attached to the operating arm 1 In the table saw provided between the lower guard 4 and the hinge member 3 so as to expose the saw blade by rotating the lower guard 15 when the safety guard 4 moves downward, the saw blade is cut at one end of the lower guard 4. A pointer 30 indicating a position for cutting an object is attached by a screw 33 stopper or a welding stopper, a rivet stopper or a magnet 31 for attraction.

 The pointer may be a one-piece plate-shaped one, or may be a pointer capable of adjusting the protruding amount as shown by 32 in FIGS. 1 and 5, and may be an articulated link-shaped one not shown. Of course, the good thing is that it is convenient to fix it at an arbitrary position according to the size of the workpiece and set the indicated position.

(Operation) The above technical means operates as follows.

 Since the pointer for indicating the cutting position is provided on the lower guard 15 that rotates in conjunction with the vertical movement of the safety guard 4, the pointer of the present invention is close to the workpiece when the safety guard 4 is positioned above. It acts to separate from the work piece as it is pushed down.

(Effect of the Invention) Therefore, the present invention has the following effects.

 That is, when the work piece is placed on the surface plate 1, that is, when the safety guard is above, the pointer of the present invention is near the top of the work piece, and the cutting position can be accurately visually observed. When the safety guard is rotated downward, it moves away from the work piece together with the lower guard to a position where it does not hinder cutting, improving work efficiency.

Claims (1)

[Scope of utility model registration request] On the hinge member 3 of the surface plate 1, the base end of the safety guard 4 is vertically pivotable and supported by a fulcrum shaft 5, and the vicinity of the base end of the lower guard operating arm 17 can be pivoted on the fulcrum shaft 5. In addition, the lower guard 15 which is rotatably urged in one direction by a spring 20 and pivotally supported, and which is interlocked with the operating arm 17 via a link 18 is rotated to the bearing portion 14 of the circular saw mounting drive shaft 9. The safety guard 4 is connected so as to be movable.
A cutting position pointer device for a table saw, characterized in that a pointer for indicating a cutting position of a saw blade is attached to a lower guard 15 configured to rotate in association with the vertical rotation of the saw.
