DESCRIPTION OF THE PREFERRED EMBODIMENTS A grip scissors with a cap according to an embodiment of the present invention will be described below with reference to the drawings.

<Overview of grip scissors shown in FIG. 1> The grip scissors include a grip scissors body 1 composed of a pair of grip handles 2 and 3, and a plastic cap 4 (described in detail later).
The grips 2 and 3 can be separated from each other, and are composed of plastic grips 5 and 6 and metal blades 7 and 8, respectively. The grips 5, 6 are attached to the blades 7, 8 during molding. As shown in FIG. 2A, a rotation support 9 is formed on the grip 5 on the base end side of one handle 2 and the other handle 3 as shown in FIG. 2B. On the base end side of the gripping portion 6, a turning support portion 10 is formed, and these turning support portions 9, 10 are detachably inserted into each other. The blade 7 protrudes from the grip 5 on the tip side of one handle 2 and the blade 8 on the tip side of the other handle 3.
6 protrude from the grip portion 6, and as shown in FIG. 6 (b), the cutting edges 7a, 8a are formed at opposing inner edges of the blade portions 7, 8.

The grips 2 and 3 can be opened and closed with respect to their rotation supporting portions 9 and 10 respectively. Each of the grips 2 and 3 is provided with a lock mechanism 11 (described in detail later). As shown in FIG. 6B, the lock mechanism 11
Is in the unlocked state, both grip handles 2 and 3 are opened within a predetermined angle range by the elastic force of a spring (not shown) fitted in the rotation supporting portions 9 and 10. As shown in FIG. 6A, when the lock mechanism 11 is in the locked state, the grips 2 and 3 close each other against the elastic force of the spring (not shown).

The cap 4 covers the two blades 7, 8 as shown in FIG. 1 (a) in the locked grips 2, 3 in the locked state, and the two blades 7, 8 as shown in FIG. 1 (b). ,
8 is removed. Incidentally, the operation of the lock mechanism 11 accompanying the attachment and detachment of the cap 4 will be described later in detail.

<Locking mechanism 11 shown in FIG. 1> An operating knob 12 is provided at the inner edge of the grip 5 of one grip 2 among the opposing inner edges of the grips 5 and 6 of the grips 2 and 3. The (operation unit) is movably supported. As shown in FIGS. 2 (a) and 4 (a), the operation knob 12 includes a front contact finger 13 which is also exposed to the front side of the gripper 5, and a finger guide 13 which also serves as a front guide. As shown in FIG. 6, a back guide 14 exposed on the back side of the grip portion 5, and a locking plate portion 15 (locking portion) formed between the finger contact portion 13 and the back guide 14 as shown in FIG. have. This operation knob 1
2 is on a plane including the opening / closing movement direction X of both grip handles 2, 3;
It moves linearly along the longitudinal direction Y connecting the proximal end and the distal end of both grip handles 2 and 3, and can take a lock position P shown in FIG. 2 and an unlock position Q shown in FIG. On the other hand, as shown in FIG.
Grip portion 6 of the other handle 3 of the opposing inner edges of
On the inner edge side, a locking concave portion 16 (locking portion) is formed.

* Operation knob 1 at the lock position P
2 As shown in FIG. 2, the operation knob 12 moves to the base end side of one handle 2. The fingertip 1 of the operation knob 12
The unlocking portion 17 extending from the rotation support portion 3 is provided near the rotation support portions 9 and 10 of the grip handles 2 and 3.
It enters into a concave retreating portion 18 formed so as to surround 10. As shown in FIG. 6A, the locking plate 15 of the operation knob 12 is engaged with the locking recess 16.

* Operation knob 12 at the unlock position Q As shown in FIG. 4, the operation knob 12 moves to the tip end of one handle 2. The fingertip 1 of the operation knob 12
The lock portion 19 formed on the handle 3 and the back guide 14 protrudes toward the blades 7 and 8 of the grips 2 and 3. FIG. 6 (b)
As shown in FIG. 5, the locking plate 15 of the operation knob 12 is detached from the locking recess 16.

<The cap 4 shown in FIG. 1> The cap 4 has a case 20 and a pair of arms 21 projecting from an opening 20a of the case 20. As shown in FIG. 3A, one arm 21 of the two arms 21 is an unlocking portion that can contact the unlocking portion 17 of the operation knob 12. In addition, the arms 21
As shown in FIG. 5, is a lock portion that can abut both lock portions 19 of the operation knob 12.

<Operation of the lock mechanism 11 in connection with the attachment and detachment of the cap 4> * Non-use state A shown in FIG. 2 With the blades 7, 8 of both grip handles 2, 3 closed, the operation knob 12 is turned on. As described above, it is at the lock position P, and the opening and closing movement of both grip handles 2 and 3 is prevented. The lock release portion 17 of the operation knob 12 projects to the retreat portion 18 of the handle 2, and the lock portions 19 of the operation knob 12 retreat from the blades 7 and 8. The cap 4 is put on the blades 7 and 8, and the arms 21 of the cap 4 match the grips 5 and 6.

* The intermediate state shown in FIG. 3 (non-use state A →
Usage state B) In the non-use state A shown in FIG.
To release the two blades 7 and 8 and remove the cap 4
Is fitted into the retracting portions 18 of the grips 2, 3, and one arm 2 of the two arms 21 of the cap 4 that becomes the unlocking portion
1 contacts the unlocking portion 17 of the operation knob 12.

* Use condition B shown in FIG. 4 From the middle state shown in FIG.
Is completely fitted into and supported by the retracting portion 18 of the cap 4, the arm 21 (lock release portion) of the cap 4 operates the operating knob 1.
The second unlocking portion 17 is pushed, and the operation knob 12 is in the unlocking position Q as described above. Therefore, the opening and closing movements of the grips 2 and 3 can be performed in a state where the blades 7 and 8 of the grips 2 and 3 are open to each other. The lock release portion 17 of the operation knob 12 retreats from the retraction portion 18 of the handle 2, and the lock portions 19 of the operation knob 12 protrude toward the blades 7, 8.

* The middle state shown in FIG. 5 (use state B → non-use state A) In use state B shown in FIG.
When the cap 4 is disengaged from the evacuation portion 18 and the cap 4 is fitted into the two blade portions 7 and 8, both the arm portions 21 of the cap 4 contact the two lock portions 19 of the operation knob 12 while the two blade portions 7 and 8 close each other. Touch

Further, when the cap 4 is completely fitted into the blades 7 and 8, both the lock portions 19 of the operation knob 12 are pushed by the both arms 21 (lock portions) of the cap 4.
The operation knob 12 is at the lock position P. Therefore, FIG.
To the non-use state A shown in FIG.

<Characteristics of the above-described embodiment> The above-described embodiment has the following characteristics * (other than other technical ideas described later). * The cap 4 that covers the blade portions 7 and 8 of the grips 2 and 3 in the non-use state A can be supported by the retracting portion 18 of the grips 2 and 3 in the use state B. Therefore, cap 4
Can be prevented from being lost.

In the non-use state A, the locking mechanism 11 can prevent the opening and closing movement of both grip handles 2 and 3. Therefore, even if the cap 4 is detached from the blades 7 and 8 of the grips 2 and 3, the blades 7 and 8 will not be opened carelessly.

When the cap 4 is moved from the non-use state A to the use state B, the lock mechanism 11 pushes the lock release section 17 of the operation knob 12 with the arm mechanism 21 (lock release section) of the cap 4 to release the lock. be able to. Conversely, when the cap 4 is moved from the use state B to the non-use state A, the arm 21 (lock portion) of the cap 4 allows the lock mechanism 11 to push and lock the lock portion 19 of the operation knob 12. Therefore, the cap 4 can be unlocked by the cap 4 at the same time as the use state B, and the cap 4 can be locked by the cap 4 at the same time as the non-use state A. Therefore, the attachment / detachment operation of the cap 4, which normally has only the cover function, can also be used as the lock release operation and the lock operation in the lock mechanism 11, and the operation becomes easy.
