Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a tabletop tape cutter that rotatably supports cellophane tape, double-sided tape, etc., and is capable of cutting these tapes to a desired length. .

(Prior Art) In conventional tape cutters of this type, the blade for cutting the tape is exposed and fixed at the upper front of the tape cutter body placed on a tabletop.
When the tape cutter is not being cut, for example, when the tape cutter is being carried around, the blade may come into contact with fingertips and cause injury, which poses a safety problem.
Therefore, as a solution to this problem, Jitsukaiaki
Japanese Patent No. 55-82248 discloses a tape cutter body in which a cover body that covers the entire upper part including the tape and the blade portion is detachably fitted.

However, with such a device, the large cover body must be fitted over the entire upper part of the tape cutter body or removed from the tape cutter body, making operation very cumbersome. If you grab the tape cutter with one hand, the cover will come off and the tape cutter will fall.
There is the inconvenience of having to use both hands carefully when carrying and installing the tape cutter. Furthermore, since the cover body is detached from the tape cutter body, it is easy to lose the cover body when the tape cutter is used, and since it covers unnecessary parts such as the tape, the material cost of the cover body increases, resulting in an increase in cost.

In addition, as a means to prevent the tape cutter body from falling and the cover body from being lost, it is possible to attach the front or rear side of the cover body to the tape cutter body in a rotatable manner. For those that cover the entire upper part, if the front side of the cover body is attached to the tape cutter body, the opened cover body will get in the way when using the tape cutter, and if the back side of the cover body is attached to the tape cutter body, when opened. A problem arises in that the rear of the tape cutter body must be left wide open in consideration of the size of the cover body.

(Purpose) This invention was devised in view of the above problems.
When the tape cutter is not in use, it not only prevents the blade from coming into contact with fingertips, but also reduces the trouble of operating the cover body as mentioned above, inconvenience when carrying and installing it, loss of the cover body, and material costs. It is an object of the present invention to provide a tape cutter that can prevent the bulkiness of the tape cutter, and that the opened cover body does not get in the way when the tape cutter is used, and that does not cause the problem of having to leave a wide space at the rear of the tape cutter body. .

(Structure) The present invention has a blade section on the front side of the tape cutter body, and a pair of support sections on the rear side of the blade section that support the shaft of the reel on which the tape is placed. In order to achieve the above-mentioned purpose in a tabletop tape cutter that cuts the tape fed out by the blade, the tape cutter covers the blade and is fed forward by rotation with the blade covered. The cover body includes a cover part to which a tape can be adhered to the upper surface part, and a pair of legs extending downward from both sides of the cover part to straddle the front part of the tape cutter main body. The pair of legs of the cover body are attached to both sides of the front side of the tape cutter body so that the cover body can be rotated on the front side between a position that covers the blade part and a lower position that does not interfere with the tape that is fed out ahead of the blade part. It is pivotably attached to the.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The tape cutter main body 1 placed on a table is roughly divided into a side wall 11 at the rear, a bottom wall 12 at the bottom, and a support 13 for the blade 14 at the front. Book legs 12a, 12a
The bottom plate 15 is fixed to these legs 12a, 12a using snap springs 12b, 12b. Reference numeral 16 is a weight for stabilizing the tape cutter body 1, and reference numeral 17 is a non-slip member spread on the bottom plate 15. A reel holder 2 is placed on the upper end surface of the side wall portion 11, and a reel 3, in which the inner peripheral surface of the tape 4 is press-fitted and arranged, is rotatably supported on the reel holder 2. The side walls 21, 21 of the holder 2 have a double structure, and support parts 21b, 21b for the reel 3, which are cut out in a substantially rectangular shape, are formed at the front upper part of the inner side walls 21a, 21a.
The central shaft 31 of the reel 3 is mounted on b and 21b.
Further, a plurality of grooves 21d are formed on the outer surfaces of the outer side walls 21c, 21c, so that the reel holder 2 can be held stably, and the reel holder 2 is aesthetically pleasing.

A groove 13a is formed in the upper part of the support part 13, and a blade part 14 is inserted into the groove 13a as shown in FIG.
The blade portion 14 is press-fitted and fixed, and the blade portion 14 has a portion 14a having an arcuate cross-section formed in the press-fit portion in order to strengthen elasticity. In addition, a stepped portion 13b is formed on both front sides of the supporting portion 13 from the upper end to the middle portion, and the cover body 5 is held in contact with the stepped portion 13b.
Through holes 13c, 13c are bored in the lower part of both sides of b, and the cover body 5 is inserted into these through holes 13c, 13c.
The cover body 5 is pivotally attached to the support portion 13 by passing through the shaft portions 52a, 52a. On the other hand, the stepped portion 3b
Engagement grooves 13d, 13d are provided at the upper portions of both sides of the
an engaging protrusion 52b formed on the cover body 5,
52b, the cover body 5 is to be locked in a state covering the blade portion 14. Further, a rectangular notch 13e is provided at the lower end of the front surface of the support part 13, so that the cover part 51 of the cover body 5 can be accommodated so that the cover body 5 does not get in the way during tape cutting.

The cover body 5 covers the blade part 14 and covers the blade part 1.
A cover part 51 that can adhere to the upper surface part the tape 4 that is fed forward by rotation while covering the tape 4;
The front part (supporting part 13) of the tape cutter main body 1 extends downward from both sides of the cover part 51.
The cover part 51 has a cross-sectional shape as shown in FIG. It is formed into an L-shape, and the length in the front-rear direction at the inner diameter is made to match the length in the front-rear direction of the upper surface of the stepped portion. Therefore, when covering the blade portion 14 of the cover body 5, the cover body 5 does not protrude forward and become unsightly.

On the other hand, the cover body 5 of the leg parts 52, 52 is
4 is in an L-shape so that it is housed in the stepped portion 13b, and shaft portions 52a, 52a are protruded from the lower inner surfaces of the legs 52, 52. Wedge-shaped flange portions 52c, 5 are provided at the tips of these shaft portions 52a, 52a.
2c, and the through holes 13, 13 of the support part 13
Once the shaft portions 52a, 52a are inserted into the shaft portion c, they will not come out. In addition, the leg portion 52,
Engagement protrusions 52b, 52b are formed on the inner surface of the upper part of the cover body 5, and the engagement grooves 13d, 13d are elastically engaged using the elasticity of the cover body 5, and the cover body 5 is connected to the blade portion. It is designed so that it can be stably locked in the covered state of 14. Furthermore, a protrusion 52 having a sawtooth-like uneven surface is provided on the upper outer surface of the leg portions 52, 52.
d and 52d, making it easy to hold the cover body 5.

In the tape cutter configured as above,
At the time of tape cutting, the cover body 5 is rotated downward with one hand to store the cover part 51 in the notch 13e of the support part 13, so that the cover body 5 does not become an obstacle during tape cutting. On the other hand, when the tape is not cut, the cover body 5 is rotated upward with one hand, and the engagement protrusion 52
b, 52b are engaged with the engagement grooves 13d, 13d, and the cover body 5 is locked to the support part 13 with the blade part 14 covered by the cover part 51. It is safe and there is no risk of injury from contact with other objects.

Incidentally, as in the above embodiment, the cover body legs 52, 5
If the length of 2 is sufficient, even if the notch 13e is not provided and the cover part 51 is not housed, the cover body 5 will not get in the way when cutting the tape. The notch 13e may not be provided. In addition, the cover body legs 5
When the lengths of 2 and 52 are shortened, it is preferable to form the notch 13e so that the cover body cover part 51 can be accommodated when cutting the tape. Since the notch 13e is merely used to cover the tape 14, it does not interfere much with cutting the tape even if the notch 13e is not formed.

(Effects) As is clear from the above explanation, the tape cutter according to the present invention does not cause injury due to the blade coming into contact with fingertips, etc., except when cutting tape, making it safe. be able to.

Moreover, since the pair of legs of the cover body are pivotally attached to both front sides of the tape cutter body to be able to rotate forward with respect to the tape cutter body placed on a tabletop, the cover body can be rotated to cut the blades. When exposing the blade portion or covering the blade portion with the cover portion, this can be easily done with one hand.

Furthermore, when the blade part is exposed, the cover part of the cover body is located at a lower position where it does not interfere with the tape that is fed forward from the blade part, so when the tape is fed out forward from the blade part, When cutting with the blade, the cover part of the cover body does not get in the way, and with the cover part positioned at a lower position where it does not interfere with the tape, the tape can be continuously fed out and cut. It can be easily done many times.

In addition, when the cover is positioned at a lower position where it does not interfere with the tape, the pair of legs of the cover body are pivotally attached to both front sides of the tape cutter body, so there is no chance of losing the cover body. There isn't.

In addition, the cover part and the pair of legs of the cover body are rotated at the front where there is a space for feeding out the tape, so in order to rotate the cover body, the cover part and the pair of legs are rotated at the rear of the tape cutter or on the left and right sides of the tape cutter. There is no need to secure space on both sides, and the required space can be kept to a minimum.

In addition, the cover body of the present invention does not increase material costs and can be attached to the tape cutter body in a compact manner, and when carrying and installing the tape cutter, it can be carried and installed by holding the tape cutter body with one hand. .

In addition, in the case of the present invention, the cover part of the cover body is
Since the tape that is fed forward can be attached to the upper surface while the blade is covered,
When cutting tape that is fed out forward with scissors without using the blade, the tape can be easily cut with scissors by adhesively fixing the base side of the tape that is fed out to the top surface of the cover. There are advantages that can be achieved. Moreover, since the cut tape does not come into contact with the blade, it is not damaged by the blade.

Cutting the tape with such scissors is recommended if you do not like the jagged cut edges caused by the blade. In other words, jagged cut edges will significantly impair the appearance of the object to be adhered with the tape, or if you are cutting letters or other parts when repairing documents or drawings. It is often used when figures etc. become extremely difficult to see.

In addition, since the base side of the tape left after the cutting is adhered to the top surface of the cover part,
The tape is not wound around the tape body, and when the tape is fed out forward again, the base side is used as the feeding end of the tape, and the tape is peeled off from the upper surface of the cover part, and the tape can be easily fed out.
