Description

[Detailed description of the invention] This invention relates to a tape pasting device, and more specifically, it is mainly used for pasting tape on the floor for indoor sports such as volleyball, basketball, etc., for dividing courts, marking lines, etc. indoors such as gymnasiums. The device used is capable of accurately depicting the target attachment line, such as a straight line or arc.

Conventional line drawing tape adhering devices of this type include, for example, the one disclosed in Japanese Utility Model Application No. 57-200260, in which rolling wheels and press rollers are installed on a frame so that they can touch the floor when in use, and a tape supply roller is wound around the tape. is installed in front of and above the holding roller, and a steering handle is set upright on the frame, and the adhesive tape wound around the supply roller is pressed and adhered to the floor surface by the pressure roller while the steering handle is pushed forward by hand with the steering handle. There is a known method in which lines are drawn using tape.

However, with such conventional devices, the steering handle cannot be operated as desired, making it difficult to accurately draw the desired attachment line, such as a straight line or an arc. It is extremely difficult to maintain a constant deflection angle when Furthermore, because the pressure roller is only pivotally mounted to the frame, there remains the problem that when the floor surface is sloped or uneven, the pressure roller presses the tape unevenly, resulting in incomplete tape adhesion. .

The present invention was devised to solve these conventional problems, and its gist is to facilitate the operation of the steering handle and to enable the steering handle to be held at a constant turning angle. Tape adhesion by making it possible to easily and accurately draw the adhesion line, and by making it possible to press the tape by adapting the pressure roller to the floor surface even if the floor surface is sloped or has depressions. The main point is that it can be carried out reliably.

To explain the following with reference to the attached drawings, a frame 1 has a front height, and one or more driven wheels 2 are attached to the rear part of the frame 1 so as to be able to rotate independently, for example, on a rear axle 3 that is integrated with the frame 1. A shaft 5 connected to a steering handle 4 is rotatably attached to the front part of the frame. That is, as shown in FIG. 5, a base cylinder 7 integrally fixed to the upper surface of the support member 6 by welding or bolting is projected upward through a hole 8 in the front part of the frame, and the shaft 5 is fitted into the base cylinder 7. By tightening the set screw or bolt 9 provided on the base cylinder 7, the steering handle 4 and the support member 6 are fixed relative to the frame around the rotation of the base cylinder 7 in the hole 8. It can be rotated horizontally. Further, as shown in FIGS. 2 and 4, a steering fixing plate 10 having a hole 11 that matches and communicates with the hole 8 and having a disk shape or the like in plan view is integrally welded or bolted to the lower surface of the front part of the frame. Install this steering fixing plate 1.
0 has a circular arc-shaped long groove 12 concentric with the hole 11 and a scale 13
, and is screwed into a screw hole (not shown) in the center of the upper surface of the support member 6 in the width direction.
By fitting the threaded shaft 14 with a knob into the arcuate long groove 12 so as to be able to slide in the groove and tightening the threaded shaft 14 with a knob, the steering handle 4 support member 6 is fixed as shown in FIGS. The horizontal rotation angle, that is, the steering angle, of the pressure roller 15 attached to the support member 6 relative to the frame 1 can be kept constant. In this case, by using an appropriate position such as the center of the knob 14' as a marker for the scale 13, the steering angle can be numerically determined using the scale 13. It is also possible to form a wide part in the front part of the frame 1 and form it directly on this wide part, or further, to provide a screw shaft 14 facing upward on the upper surface of the support member 6 and fit the screw shaft into the arc-shaped long groove 12. project upward through the
It is also possible to screw the knob 14' into the protrusion.

Thus, if the support member 6 is integrally fixed with the flat plate 16 on its upper surface by welding or other means, the flat plate 1
By connecting the upper smooth surface of the support member 6 to the front part of the frame or the lower surface of the steering fixed plate 10, the support member 6 can be smoothly rotated with respect to the frame 1. In addition, the support member 6 has a weight of more than a predetermined value in order to generate the necessary pressing force for tape adhesion without applying too much load to the handle 4 when adhering the tape by pressure using the pressure roller 15 installed below the support member 6. In addition, a mounting bracket 17 that pivotally supports the pressure roller 15 is provided at the center of the width direction of the front and rear walls 6', 6'' of the support member 6.
is mounted so that it can be rotated in the lateral direction, that is, swingable around the pivot shaft 18 in the front-rear direction. By rotating the metal fitting 17 in the lateral direction, it can be used along an inclined or uneven surface, and tape adhesion can be performed reliably.

On the other hand, the supply roller 19 for winding and supporting the tape and feeding it toward the pressure roller 15 includes arms 20 fixed or rotatably pivoted to both sides of the support member 6;
The arm 20 is rotatably supported by a pivot 21 that is detachably provided between the arms 20 and 20.More specifically, as shown in FIG. The pivot 21 can be prevented from coming off by removably hooking a stopper 22 which is formed and rotatably pivoted to the outer surface of the arm 20 on the stepped portion 21'. The rotating cylinder 23 is fitted into the rotating cylinder 23, and the two-part body 19' is attached to the rotating cylinder 23.
A supply roller 19 consisting of a screw 24 is fitted and fixed to be rotatable integrally with the rotary cylinder 23, and a stepped portion 25, 2 is provided at the proximal end of both the divided bodies 19' as shown in the figure.
6 and both steps 2 according to the inner diameter of the tape T.
5 or 26 to tightly fit and support a large diameter tape or a small diameter tape.

In the figure, 7' is a base cylinder for changing the mounting position of the steering handle 4.

According to the present invention as described above, the supply roller 19
The steering handle 4 provided at the front of the frame 1 and the pressure roller 1 are used to attach the wound tape T to the floor surface using the pressure roller 15 as the device moves forward.
Since the supporting member 6 supporting the steering wheel 5 is integrally attached to the frame 1 so as to be horizontally rotatable, the pressing roller 15, which is located at the front of the frame and also serves as a steering wheel, can be moved by operating the steering handle 4. The tape application line can be easily steered, and the tape application line of the present invention can be arbitrarily selected to be a straight line or a curved line such as an arc.

Further, as an effect based on other embodiments of the present invention, first, the mounting bracket 17 that supports the pressing roller 15 is
By attaching it to the support fitting 6 so that it can rotate laterally, even if the floor surface to which the tape is applied has an inclined or uneven surface, the pressing roller 15 can be moved along the inclined or uneven surface to continue the tape application. This eliminates the drawback of incomplete adhesion due to one-sided pressing of the tape, and the steering fixing plate 10 is fixed to the lower surface of the front of the frame, and the arc-shaped long groove 1 formed in the steering fixing plate 10 can be fixed to the front lower surface of the frame.
2 and a steering fixing means consisting of a screw shaft 14 with a knob fitted in the long groove, the curvature of a straight line or an arc can be arbitrarily determined when applying the tape.
By moving the device straight or fixing it at an angle, the desired tape application line can be easily drawn by simply moving the device forward.
