Description

[Detailed description of the invention] (Field of industrial application) This invention relates to scissors that can be folded when not in use.

(Prior art) Conventionally, as this type of scissors, for example, the 9th and 10th scissors
There is one shown in the figure. In this scissor, both blades 1 are supported by an opening/closing center shaft 6 so as to be able to open and close with respect to each other in the direction of the arrow A, and a handle 10 is attached to the base end of the blade 1 in the direction indicated by the arrow B, which is the same as the opening/closing direction A of the blades 1. They are connected by a support pin 21 so as to be rotatable in the direction. Then, from the usage state shown in Fig. 9, both handles 10
When the handles 10 are rotated in the direction of arrow B, both handles 10 are folded against the blade 1, as shown in FIG.

In the case of such scissors, since the opening/closing direction A during use is the same as the rotation direction B when folding, it is necessary to restrict the rotation of the handle 10 with respect to the blade 1 by some means during use. In this example, a presser foot 22 is provided on the handle 10, and the tip of the presser foot 22 presses the vicinity of the support pin 21 of the blade 1 to restrict rotation.

(Problem to be solved by the invention) However, since the presser foot 22 is required to have a strong elastic force that can withstand the opening and closing operations of the scissors during use, the presser foot 22 must resist the elastic force of the presser foot 22 when folding. It was necessary to rotate the handle 10 with great force, making it difficult to fold.

Furthermore, since it is dangerous to hold the blade 1 in your hands when folding the scissors, if you try to fold it by holding only the handle 10, both blades 1 will inevitably open as shown in Figure 11. If the handle 10 was rotated in this state, there was a risk of injury due to the blade 1.

Therefore, by making the rotation direction when folding the handle perpendicular to the opening and closing direction of both blades,
The present invention allows for safe and easy folding.

Structure of the invention (means for solving problems) That is, the invention consists of a central axis 6 for opening and closing the double blade 1, as shown in FIGS. 1 to 5 in the drawings of the embodiment described later.
The handle 10 is connected to the base end of both blades 1 so as to be rotatable in a direction B perpendicular to the opening/closing direction A, so that the blade 1 and the handle 10 are supported so that they can be opened and closed.
and foldable, and the blade 1
A locking tongue piece 7 is attached to either the base end of the handle 10 or the handle 10.
is provided on the other side, and locks with the locking tongue piece 7 to lock the handle 1.
A locking edge 12 is provided for regulating the amount of rotation of the blade 1, and the proximal end of the blade 1 and the handle 10 are fitted and fixed in an uneven relationship when the scissors are in use. The fitting concave and convex portions 14 and 9 are provided.

(Function) When both handles 10 are rotated in the direction B perpendicular to the opening/closing direction A of the blades 1 as shown in FIGS. 6 to 8, the handles 10 rotate around the proximal end of the blade 1. The scissors are folded.

In addition, the locking tongue piece 7 and the locking edge 12 provided on the proximal end of the blade 1 and the handle 10 allow the blade 1 of the handle 10 to
The amount of rotation is regulated.

Furthermore, the fitting uneven parts 14 and 9 provided on the base end of the blade 1 and the handle 10 prevent the handle 10 from inadvertently rotating in the direction B when the scissors are in use. . Furthermore, even when both handles 10 in this state are rotated in the direction B, one of the recesses 9
When the other protrusion 14 is removed from the handle 10, the handle 10 is rotated relative to the blade 1.

(Example) Examples 1 to 8 which embody the present invention will be described below.
This will be explained according to the diagram.

As shown in FIGS. 1 and 5, each of the pair of blades 1 consists of a blade body 2 and a support member 3. A fitting recess 4 is formed on the inner surface of the distal end side of the support member 3, and the base end portion of the blade body 2 is fitted into the fitting recess 4. An insertion hole 5 is provided in the fitting recess 4 of the support member 3 and the base end of the blade 2, respectively. As shown in FIG. 2, a pair of opening/closing central shafts 6 are fitted into the insertion hole 5 and can be fitted into each other. As a result, the double blades 1 are supported by the opening/closing central shaft 6 so as to be openable and closable in the direction of the arrow A in a mutually overlapping state. Further, a locking tongue 7 is provided protruding from the base end side of the support member 3, and a support recess 8 and an engagement recess 9 are formed on both side surfaces of the support member 3.

Both support arms 11 are protruded from the base ends of the pair of handles 10, and a locking edge 12 is provided between the base ends of both support arms 11.
is formed in a stepped shape, and a support protrusion 13 and an engagement protrusion 14 are formed on opposing inner surfaces of the support arm 11. Also, each pattern 10
A blade storage recess 15 is formed on the outer surface of the support arm 11, and the blade storage recess 15 is open between the base ends of both support arms 11. The support member 3 of the blade 1 is fitted between both support arms 11 of the handle 10, and the support protrusion 1 of the support arm 11 is fitted as shown in FIG.
3 is fitted into the support recess 8 of the support member 3.
As a result, as shown in FIG.
They are rotatably connected so as to be separated from each other in the direction of the arrow.

Now, when the scissors are in use, the locking edge 12 of the handle 10 comes into contact with the locking tongue 7 of the blade 1, as shown in FIG. This prevents the blade from rotating in the direction of arrow B with respect to the blade 1. In addition, as shown in FIG. 3, the engagement convex portion 14 of the handle 10 engages with the engagement recess 9 of the blade 1, so that the handle 10 is in the above-mentioned state of use.
prevents the blade from rotating inadvertently in the direction of arrow B relative to the blade 1.

In this way, the handle 10 is rotatable relative to the blade 1 only in the direction of the arrow B perpendicular to the opening/closing direction A, and cannot be rotated in the opening/closing direction A. Therefore, unlike the conventional folding scissors shown in FIGS. 9 to 11, there is no need to restrict the rotation of the handle 10 by the presser foot 22 during use, and the structure of the scissors is simplified.

Next, when folding these scissors, first
When one handle 10 is rotated as shown in FIGS. 7a and 7b from the usage state shown in the figure, the engagement protrusion 14 of the handle 10 is disengaged from the engagement recess 9 of the blade 1, and the handle 10 is rotated as shown in FIGS.
is rotated 180 degrees in the direction of arrow B, and one blade body 2 is stored in the blade body storage recess 15 of the handle 10.

Then, as shown in FIG.
When is similarly rotated 180 degrees in the direction of arrow B, this handle 10 overlaps the already folded handle 10, and the other blade body 2 is stored in the blade housing recess 15 of this handle 10. Therefore, the double blade bodies 2 are stored in the blade housing recesses 15 of both handles 10 while being held between the handles 10.

In this way, since the blade body 2 is stored by the handle 10 when not in use, it is safe even when carried.

Particularly, in this embodiment, unlike the conventional example shown in FIGS. 9 to 11, there is no need for a large force to resist the elastic force of the presser foot 22 when folding, making it easier to fold. Furthermore, since the blades 1 can be easily folded by holding only the handle 10 without opening, there is no risk of injury from the blades 1.

Conversely, from this folded state, turn both handles 10
When it is rotated in the direction of the arrow, it enters the usage state shown in FIG. 6.

Note that in this embodiment, the blade body 2 and the support member 3 in the blade 1 are separated, but they may be integrated.

Effects of the invention In short, according to the invention, since the rotation direction B when folding the handle 10 is made perpendicular to the opening/closing direction A of the double blade 1, unlike the conventional example, there is no need for a presser foot, and the folding Sometimes, a large force to resist the elastic force of the presser foot is no longer required, making it easier to fold, and furthermore, the blade 1 can be easily folded by holding only the handle 10 without opening both blades 1.
It is very safe with no risk of injury.

In addition, the locking tongue piece 7 and the locking edge 12 provided on the proximal end of the blade 1 and the handle 10 allow the blade 1 of the handle 10 to
Since the amount of rotation relative to B is regulated, the handle 10 is
Rotation in the direction can be reliably prevented.

In addition, by providing the proximal end of the blade 1 and the handle 10 with fitting uneven parts 14 and 9 that fit and fix these in an uneven relationship when the scissors are in use, the handle 10 is fixed in the use condition. This prevents careless rotation in the B direction and greatly improves the operability of the scissors. Furthermore, even when both handles 10 are rotated in the direction B, the handle 10 can be rotated with respect to the blade 1 by removing the protrusion 14 from the recess 9 of one side. The folding process does not become a hassle.
