Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that the tip working piece for performing cutting and other operations is rotated about a pivot, as can be seen in manual tools such as scissors, plywood benches, and strippers. Regarding the hand-held opening/closing work tool that can be opened and closed as a device, its specific configuration includes a hand-held cover case with an elongated slide guide hole, and a cover case that can be rotated freely into the case and always protrudes from the case to open. The opening/closing operation lever is held in a state in which it is elastically biased in the direction, and the lever is operatively connected to the lever so as to receive the elastic force of the lever, and the lever rotates about the pivot for assembly into the case. The bar is made to lie down in the case while resisting its elastic force, and in this state, the pivot of the piece is slid along the guide elongated hole of the case. As a result, it is characterized by the fact that the piece is also stored in a immersed state within the case.

In general, a hand-held opening/closing work tool with a mechanism for cutting, pushing out, or contracting a certain item by means of an end-acting piece that opens and closes around a certain pivot point is ``specifically represented by various types of scissors.'' In practice, it is widely used as hand tools such as pliers and bench hair strippers, as well as hand tools such as pliers and bench hair strippers. Usually, the pins or jaws are made of metal material, so there is always a risk of getting your hands or fingers caught in the pins and getting injured. The cutting blade body, which is a piece, and its opening/closing operation lever, which also forms a keynote arm, are made into a continuous and rigid piece, and a pair of such shapes is thinly attached to be rotatable by a pivot in the middle. It becomes.

Although the pair of cutting blades remains closed during the inconvenience of using the scissors, there is no change in the fact that the scissors are left unchecked, and therefore it is still dangerous. It is also inappropriate to carry the scissors around in a bag, etc.In this respect, even if the scissors are equipped with a mechanism that locks the opened state, unless the sharp cutting blade is enclosed. ~ After all, it is difficult to say that it is safe.Therefore, when using or carrying the scissors, it is recommended to store the entire scissor completely in the case as in the store-bought condition, or to store only the cutting blade in a sheath. However, the case and other issues are completely separate from the scissors themselves, so it is necessary to specially manufacture and prepare them, and even if these are prepared as accessories. It is troublesome to take the scissors in and out of them, and they often get lost.Furthermore, even if you store them in a case or sheath, the overall size of the scissors will not be reduced in the slightest. On the contrary, the problem is that the scissors become loose and move around inside the case or sheath, making it especially inconvenient to carry.The present invention is a hand-held device that helps solve these problems. In particular, as seen in the hand tools such as the above-mentioned scissors and other hand-operated tools, there is a need for "tip-acting pieces that directly act on cutting and other operations." The object or starting point of the invention is a hand-held opening/closing tool that can be opened and closed about a certain pivot axis.

That is, the object of the present invention is to first create the tip-acting piece, which is embodied as the above-mentioned cutting blade, as a separate object from the opening/closing lever; By attaching silk so that it can be stored immersed in a hand-held cover case, it can be stored in an extremely safe and compact so-called folded state without the need for a separate special packaging case or sheath. The main point is to make it convenient to carry around.

The second purpose is to operatively connect the tip working piece and its opening/closing operation lever so that they are always pushed out from the cover case in an elastically biased state, and to be used for assembly into the case. By making the pivot of the piece slidable into the elongated slide guide hole of the case,
By simply sliding the axis of the piece in the front-back direction with the fingertips of the operator's hand holding the case, the state of the piece bar in relation to the case and the state of its extension can be easily and correctly changed. It is in.

Furthermore, the third objective is to use a pair of opening/closing operation levers for the piece that also serves as a cover case, and to partition a slide guide elongated hole between the opposing sides opened in the prone state, and to insert the slide guide elongated hole into the guide elongated hole. By sliding the axis of the piece along the axis, a separate cover case is not required in order to achieve the above object, and the mass production effect can be expected to be maximized.

Hereinafter, the present invention will be explained with reference to preferred embodiments shown in the drawings. The figures show the present invention applied to scissors, and in Figs. It is a cover or case that also has a grip function, and is made from metal or preferably synthetic resin, and is sometimes colored.

In this case, the two-part body is assembled virtually in a state of joining hands, and the tip acting piece, which will be described later, and its opening/closing operation lever can both be received and stored in the hollow interior. In other words, the turtle 2 is the case body that forms one of the two halves, and the wing 4 is the lid that forms the other, and both are detachably attached using a plurality of screws 6 (total of 3 in the figure). The silk attachment is integrated.

Each of the screw turtles 6 is screwed into a barrel tube group that projects horizontally inward from the case body 12 and the lid body 1. The two koji cylinder portions that are to receive a pair of upper and lower screws 16 also serve as a pivot shaft 18 of an operating lever, which will be described later. Therefore, even if the screw 6 is removed, the lever will not immediately fall off from this pivot angle 8, and therefore assembly and disassembly operations can be performed easily. Reference numeral 20 denotes a slide guide groove formed on the inner surface of the side wall of the case body 10, which extends in an elongated manner along the longitudinal line D of the case 10 itself.
Reference numeral 22 denotes a slide guide elongated hole penetrated through the side wall of the lid body 14, which also extends in the front-rear direction, and is parallel to and correctly faces the guide groove 20.

It goes without saying that the lengths of the guide grooves 29 and the guide slots 22 are sufficient to allow the working piece, which will be described later, to be inserted into the case Q. The case body 8, which is formed by attaching the case body i2 and the lid body 4, has two bar exit openings on both the upper and lower walls, and piece exit openings 26 on the front wall.・Ru. still"
In the figure, the case body 12 and the lid body 14, which are divided into equal parts, form the case 10 itself.The one to distinguish between them is called the case body weight 2, and the other one is named the lid body 1 turtle. ``For example, one could have a deep box shape, so to speak, and the other could have a simple flat plate shape, and finish with the same case wing roar.Also, both could be made to have the same symmetrical shape, and the guide grooves described above could be made. 20 may be opened in a penetrating state in exactly the same way as the guide elongated hole 22. In any case, the working piece and its operating lever, which will be described later, are similar to case 1.
Along with the 0 line, it is attached with silk, so that the case body 2 and the lid body 1 are sandwiched from both the left and right sides, so to speak.
Never falls off. Further, a pair of opening/closing operation levers made of metal or preferably synthetic resin are rotatably coupled to the bran 18 of the case turtle Q at their front ends. However, instead of using the pivot book 8 made of the barrel part of the case member Q, for example, the front end of the lever 28 can be formed into an arcuate surface. By rotating the lever 28, it is possible to pivot the lever 28 so that it can be rotated toward the case perspective.The pair of levers 28 have the same U-shaped cross section, and the levers 28 can be rotated to the case perspective. 8 are loosely attached to face each other.Therefore, the open portions of the U-shaped cross section are oriented downwardly as L on one lever 28, and upwardly as on the other lever 28.30' Lever 28
It is a piece receiving long rattan which is penetrated and closed in one side wall part of which has a U-shaped cross section, and extends along the longitudinal direction of the lever 28 itself.

The rear end of the piece is engaged with this in a detachable and slidable manner. Reference numeral 32 denotes a pair of metal tip working pieces that form the cutting blades of the scissors, and cut the object with the cutting edges machined on the front portions thereof.

Even though the axis for attaching the pair of pieces Eagle 2 to the cape turtle crab passes through the midway part where they intersect in a father-shaped shape, and around this point, piece 8 is spread around. . It is an engagement arm that is continuously bent in an L shape at the rear end of the 86-sama piece 32, and the above-mentioned receiving arm of the bar is attached to the rear end of the piece 32.
It is a helical spring that always presses the Q crab shoe and the S rate in the direction of closing the ship, which is inserted and engaged so that it can be inserted into the seal. At the same time, both ends of the separated pieces are individually locked to the rear ends of both pieces. This means that there is always pressure from Keyosu Kamewara in the direction of opening up rumors.

The pinch piece and its opening/closing control lever weight are both separate objects, but they are operatively connected in a sliding manner. The inside of the case electric light is also cut off by a screw fastening group consisting of the above-mentioned piece Kenbishi's pivot bolt turtle 8 with a sea bream, heron face, and a cap nut that fits with the bolt turtle 8.

In that case as well, the square head of the Bolt Kaoru Tai is slidably connected to the guide groove of the Case body Denro, and the synthetic resin tachibana-mami part of the Cap Puff Okina cod is the guide of the lid body Kimikame. By being guided out of the hole, it is possible to slide it back and forth from the boundary with the vermilion fingers, and also to rotate it with the fins of the small body. In other words, it is also the case of the Axis usurpation that the government's government sphere, Gabedo Choran, along with Funako, moves from the massage department to the government, and Merapihata, Hisatomi Katsuo, is in the middle of the day. It is wa which has been converted into . Even in each state, by tightening the cap nut against the bolt
Even if the bran-covered portion is pressed against the outer surface of the side wall of the case, it can be fixed and locked to prevent the sliding action. To explain the opening/closing action of the scissors based on the above-mentioned concept, ``In the usage condition, the T-piece 32 and its opening/closing operating lever 28 both exert the elastic force of the helical coil spring 38, as is clear from the figures No. 1 to Tomi. Since the case wing 8 is kept in an overhanging state from the case IQ, the lever 28 is operated with the hand holding the case wing 8. This opens and closes the piece 32 that overhangs the front and moves the object to the target object. When carrying or storing the lever, it is possible to cut it correctly.Then, when carrying or storing the lever, the fingertips of the hand that squeezes the second base lever can be used to change the state from the state shown in Fig. 5 to the state shown in Fig. 6. Slide the pivot of the piece base 2 along the guide long hole of the case turtle Q to the rear.

By doing so, the piece 3 ratio rich bar Maito's piece receiving piece will be engaged with the long groove Mitsukame, while maintaining the open state, it will slide immersively into the case Kamegiri, and here it will completely enter the case Tsubasa crab. It will be stored in. In this case, the ``peace lid'' and the bar weight crab are always engaged via the former's engagement arm 8 crab and the latter's guide Nagaiso Otoru, so that the immersed state of the lever dance crab in opposition to the game's lid is always engaged. Moko Peace Tooru 2
Therefore, the scissors themselves have a packaging case in advance so that they can be stored in an extremely safe state and can be stored in a pocket or bag of clothes. You can carry it around without danger.On the other hand, when converting from the inconvenient state of the first rumor - Guzu to the use state of the second official - horse mackerel picture, move the hazel scale turtle of the above piece 3 umbrella to the front. Just a slide operation is enough.

If this is done, both the liver bonito chicks and the Piss crab chicks will be subject to the force of the coiled spring Hōgiri, so they will be able to open at the same time with the tension from the case electric fins. In any case, even with a so-called one-touch light operation using the fingertips of one hand, it is possible to correctly convert the immersed state and the overhanging state of the pi-elbow groove board and the reba field honeysuckle, which are opposed to the rudder's full bones, into a circular turret. That's why ■Denkatsuo and Flea Illustration show deformed state (sami), and the difference is as follows, such as the basic form of the above-mentioned figure.

That is, in this ~11th edition, even if the cover case title is omitted, the function of the case rich bonito is combined with the lever bonito bonito fake. For this purpose, the contour shape of both levers W in the open state is set to be substantially the same as that of the case electric dovetail, and between the opposing sides there is a pivot 34A of piece 3 crab A.
The slide guide long hole 22A for sliding the
It is divided into a state of penetration. Therefore, the slide guide groove 2 of the case body 12 explained in the above basic form
However, in this modified form, the guide slot 20A is replaced with a through-closed guide slot 20A, but their functions are the same. Secondly, the bolt 40A that forms the pivot 34A of the piece 32A is exposed to the outside, and its head is shaped the same as the drip knob of the cap nut 42A, and is attached to the outer surface of the side wall of the lever 28A. I'm here so I can put it on.

Therefore, this modified Tachibana 34A is still made of a screw fastening body, and by tightening the nut 42A, the sliding action of the piece 32A can be fixed and locked. Thirdly, in this modified form, a pair of levers 28A that also serve as the case 10 are pivotally connected at their front ends by a leaf spring 38A,
Furthermore, the spring 38A always applies an elastic biasing force to both levers 28A in the direction of expansion.

In that case, the lever 28A and the piece 32A are engaged so that the latter can slide relative to the former, as in the above basic form, so the biasing force of the spring 38A is also received by the piece 32A. . In other words, lever 2
8A and the piece 32A are still operatively connected in motion, therefore, by sliding the pivot 34A of the piece 32A, the piece 32A and the bar 28A are moved.
can be expanded or closed at the same time, and mutual conversion can be performed. In this modified form, the other configurations and functions are self-contained and the same as those of the basic form shown in Figs. 1 to 9, so that in Figs. or a similar symbol (
1 to 9 with the suffix "A" added), and detailed explanation thereof will be omitted. In any case, according to the present invention, the above-mentioned objects can be achieved with a simple assembly made of parts that can be mass-produced. Since the invention can be easily applied to various work tools such as strippers, it can be said to be a practically useful invention.
