Description

  The present invention relates to a scissor with a case for accommodating a blade when not in use.

  Conventionally, what is described in patent documents 1 and 2 is known as this kind of bag. The scissors described in Patent Document 1 protect the blades by detachably attaching a cylindrical case having one end opened to the scissors. When the cylindrical case is attached, it houses the blade and restrains the blade so as not to open and close. However, when using a scissors, this case is removed from the scissors and is not always attached to the scissors. For this reason, when the case is required, there is a case where the case is not near the bag, which causes inconvenience in using the case.

  On the other hand, in the scissors described in Patent Document 2, the case is slidably attached to one of the pair of scissors pieces, and the blade can be accommodated by advancing the case toward the blade. It is possible. When the case moves forward, the case restrains the opening of the hook piece by engaging with the lock groove of the overlapping portion provided on the other side of the hook piece. Conversely, by retracting the case toward the gripping portion, the blade can be exposed and the engagement state with the lock groove is also released, so that the collar piece can be opened and closed. As described above, in the scissors disclosed in Patent Document 2, the case for protecting the blade is always attached to the scissors, thereby eliminating the inconvenience that the case and the scissors are separated from each other. It is expected that

  However, in the scissors described in Patent Document 2, by mistakenly applying a gripping force to the gripping part while the case is slightly advanced from the gripping part side to the blade side, When the lid is closed, the case and the overlapped portion come into contact with each other, and the contact portion is damaged by a large force amplified by the lever principle. .

  The present invention has been made in view of the above problems, and the case for housing the blade can be attached to the bag even when the bag is used, and the case is damaged by the gripping force to close the bag. The object is to provide a bag with a case that does not suffer from the damage.

  In order to solve the above-described problems and achieve the above-described object, the first aspect of the present invention is a bag with a case, and is a pair of doors that can be opened and closed by being rotatably connected to a rotating shaft. It has a sepal piece and a case. Each of the pair of hook pieces has a blade on one side with respect to the rotation shaft and a gripping part on the other side, and the other side has a trunk portion extending on an extension line of the one side, A finger hooking portion that protrudes from the trunk portion in the opening direction, and that approaches the trunk portion with a gap at a portion closer to the pivot shaft than the protruding portion. The case has a pair of case members that can be opened and closed by one end pivotably connected by a connecting portion, and is attached to the pair of scissors with the connecting portion facing the blade edge. . Further, the case is configured such that each of the pair of case members is guided by being sandwiched between the corresponding gaps so as to accommodate the blades of the pair of flange pieces and suppress the opening of the blades. It is slidable between a position advanced to the blade side and a position where the connecting portion overlaps the rotating shaft and retracted to the gripping portion so as to open and close together with the pair of hooks.

  According to this configuration, the case is guided by being sandwiched in the gap between the finger-hook portion and the trunk portion of the pair of hook pieces, along the trunk portion on one side and the other side of the pair of hook pieces, Can slide. When the scissors are not used, the blade can be accommodated and the opening of the blade can be suppressed by advancing the case toward the blade. Further, when using the scissors, the pair of scissors pieces can be opened and closed by retracting the case toward the gripping portion. In this way, the case that accommodates the blade can be attached to the scissors even when the scissors are used. In addition, when the case is displaced forward from the retracted predetermined position, the opening movement of the pair of hooks is prevented, but the closing movement is not prevented by the case. Therefore, the case is not damaged by the gripping force for closing the bag. In addition, although a case "accommodates" a blade also includes covering a blade completely, it is not limited to it. For example, the case may have a gap or a hole, and it is sufficient that the housing state is substantially realized so that the sharp part of the blade does not touch the hand from the outside.

According to a second aspect of the present invention, there is a scissor with a case according to the first aspect, wherein the case is further advanced from the position advanced toward the blade and further toward the blade edge from the blade. A first locking portion locked to at least one of the pair of gaps is provided so as to prevent the slipping out.
According to this configuration, the case can be prevented from coming out of the blade due to an erroneous manual operation.

  According to a third aspect of the present invention, there is provided a scissor with a case according to the first or second aspect, wherein the case does not retract from the position advanced to the blade side to the grip portion side. In addition, at least one of the pair of gaps has a second locking portion that is locked so as to be releasable by an elastic restoring force of the corresponding finger-hanging portion.

  According to this configuration, unless the force of a certain level is applied to the case, the case that has advanced toward the blade cannot be retracted toward the gripping portion, so that the blade accommodated in the case is not intended. It can be prevented from being exposed.

  According to a fourth aspect of the present invention, there is a case-attached scissor according to any one of the first to third aspects, and it is elastically bent and deformed to at least one of the trunk portions of the pair of scissors pieces. A beam-like spring provided in the form of a cantilever, further comprising a beam-like spring for locking the case so as not to retract from the position advanced to the blade side to the grip portion side. ing. The beam-like spring is fixed to the corresponding trunk portion so that the base end thereof is along the outer surface of the corresponding trunk portion and the distal end is directed to the rotating shaft side, and the case is When in the position advanced to the blade side, the tip springs up by an elastic restoring force so that the tip faces the end surface of the case on the gripping portion side, and the user presses the beam spring with a finger. The beam-like springs fall down and fit in the gap between the case and the corresponding trunk portion while lying down, thereby enabling the case to slide toward the gripping portion.

  According to this configuration, the case at the position advanced to the blade side is locked by the beam-like spring so as not to retreat to the grip portion side. For this reason, the blade accommodated in the case can be prevented from being unintentionally exposed. Further, when the case is retracted toward the gripping portion, the beam spring can be released from being locked by pressing the beam spring with a finger.

  According to a fifth aspect of the present invention, there is provided a scissor with a case according to the fourth aspect, wherein the case has an end face on the end face on the gripping portion side where the front end of the beam-like spring faces. A spring restraining portion for restraining the tip is provided so as to prevent the case from jumping off from the end face of the case.

  According to this configuration, it is possible to prevent the blade housed in the case from being unintentionally exposed due to the beam spring being detached from the end surface of the case.

  According to a sixth aspect of the present invention, there is provided a scissors with a case according to the fourth or fifth aspect, wherein the at least one trunk portion of the pair of scissors accommodates the fallen beam-like spring. It has a concave part.

  According to this configuration, the concave portion secures a gap for accommodating the fallen beam-like spring between the case and the flange.

  According to a seventh aspect of the present invention, there is provided a bag with a case according to any one of the fourth to sixth aspects, wherein the pair of case members are twisted together by the pressing force of the beam spring. In order to suppress the occurrence of the above, a holding member for holding one of the pair of case members is provided on the other side.

  According to this configuration, the pair of case members can be prevented from being twisted (twisted) by the pressing force of the beam-like spring.

  According to an eighth aspect of the present invention, there is provided a case-attached scissor according to any one of the first to seventh aspects, wherein the case is in the position retracted toward the gripping portion. A finger insertion cavity is formed on the inner side together with the finger hanging part of the pair of hook pieces, and the cavity is directed toward the finger hanging part and sandwiching the finger hanging part so that the outline of the cavity is smoothly connected from the case to the finger hanging part. It has a plate-like protrusion.

  According to this configuration, the contour of the finger insertion cavity has a smooth shape that is gentle to the fingers and easy to use at the joint from the case to the finger-hanging portion.

  As described above, according to the present invention, the case for housing the blade can be attached to the bag even when the bag is used, and the case is not damaged by the gripping force for closing the bag. A bowl with a case is realized.

  FIG. 1 is an external perspective view of a bag with a case according to an embodiment of the present invention, showing a form when the case is in an advanced position for accommodating a blade. This cased ridge 101 has a ridge 1 forming a main body and a case 3 attached to the ridge 1. The case 3 is slidable back and forth along the flange 1 as will be described in detail later. As an example, the case 3 has a cylindrical shape with an open front end (see FIG. 4 to be described later). As shown in FIG. 1, the case 3 accommodates the blade when it is advanced to the blade side of the heel 1. Function as. In this state, the blade of the ridge 1 is restrained by the case 3 so as not to open. When the scissors 1 are not used, the scissors 1 can be kept in a safe state by housing the blades in the case 3 as shown in FIG.

  FIG. 2 is an external perspective view of the bag 1. The scissors 1 have a pair of scissors pieces 13 and 15 that can be opened and closed by being pivotably connected to the pivot shaft 11. The flanges 13 and 15 have blades 17 and 19 on one side 16 with respect to the rotation shaft 11, and gripping portions 21 and 23 on the other side 20. On the other side (namely, the grip part side) 20, the collar pieces 13, 15 are connected to the trunk parts 25, 27 extending on the extension line of one side (namely, the blade side) 16, and the trunk parts 25, 27. Finger-holding portions 29 and 31 to be used. In the example of FIG. 2, the finger-hanging portions 29 and 31 protrude from the rear ends of the trunk portions 25 and 27 in the direction in which the trunk portions 25 and 27 open, and have gaps 33 and 35 near the rotating shaft 11. The trunks 25 and 27 are approaching. The finger hooks 29 and 31 have claw portions 37 and 39 at portions close to the trunk portions 25 and 27, and these claw portions 37 and 39 are opposed to the trunk portions 25 and 27 with gaps 33 and 35. ing. If an example of the material of each component is given, the blades 17 and 19 are made of metal such as stainless steel, and the trunk portions 25 and 27 are made of plastic in which the bases of the blades 17 and 19 are embedded, The finger hooks 29 and 31 are made of plastic molded integrally with the plastic portions of the trunk portions 25 and 27.

  A leaf spring 41 is further provided on the trunk portion 25. The leaf spring 41 has a proximal end embedded in the trunk portion 25 and fixed so as to be along the outer surface of the trunk portion 25 and so that the distal end is directed to the rotating shaft 11 side. The leaf spring 41 is a spring provided on the trunk portion 25 in the form of a cantilever that is elastically bent and deformed, and corresponds to a specific example of the beam spring of the present invention. The leaf spring 41 functions as a locking member that locks the case 3 in the forward position by having the front end thereof facing the rear end surface of the case 3. The leaf spring 41 stands slightly from the surface of the trunk portion 25 in a natural state, and can be easily laid down by finger pressure. On the surface of the trunk portion 25, a groove-like recess 43 for accommodating the fallen leaf spring 41 is formed. Further, a concave portion 44 having a cross-sectional arc shape for receiving the finger is formed on the surface of the trunk portions 25 and 27 so that the leaf spring 41 can be more easily laid down by the finger. The leaf spring 41 is made of metal as an example.

  3A is an external perspective view of the case 3, FIG. 3B is a cross-sectional view of a part of the case 3 along the AA cutting line, and FIG. 3C is a BB cutting. It is sectional drawing of a part of case 3 along a line. The case 3 has a pair of case members 7, 9, and one end of the case members 7, 9 is rotatably connected by a connecting portion 5, and can be opened and closed thereby. As illustrated in FIG. 3B, the pair of case members 7 and 9 are generally cross-sectionally “U-shaped” having surfaces that face each other (upper surface) and have a bottom wall and both side walls connected to both ends thereof. ”-Like long frame, and when it is closed, it becomes a cylindrical shape with a rectangular cross section that can be accommodated with the blades 17 and 19 closed. The connection part 5 has a pair of member arrange | positioned as an example at the both side walls of the edge part of a pair of case members 7 and 9, each of which is a board so that it may illustrate in FIG.3 (c). And a pin 51 protruding from one main surface of the plate-like body 50. The plate-like body 50 is connected to one end of the pair of case members 7, 9, for example, the end of the case member 7, and the pin 51 is inserted into the through hole 53 formed at the end of the other case member 9. By being loosely inserted, the pair of case members 7 and 9 are rotatably connected. These connecting members are made of plastic as an example, and the plate-like body 50 is fixed to the end portion of the case member 7 by adhesion, for example.

  4A and 4B are diagrams illustrating the structure of the case-equipped saddle 101 when the case 3 is in the forward position. FIG. 4A is a plan view of the case-equipped saddle 101 including a cross-sectional view of the case 3, and FIG. It is sectional drawing of a part of the collar 101 with a case along CC cutting | disconnection line. The case 3 is attached to the rod 1 in such a posture that the blades 17 and 19 pass through the case 3 and the connecting portion 5 faces the blade edge. The grip part side 20 of the pair of scissors pieces 13, 15 has trunk trunk parts 25, 27 extending on the extension line of the blade side 16, and a gap 33 is provided between the trunk trunk parts 25, 27 and the finger hook parts 29, 31. 35, the case 3 can slide back and forth along the blades 17 and 19 and the trunk portions 25 and 27 while being guided by the gaps 33 and 35.

  As illustrated in FIG. 4, when the case 3 is in a position advanced to the blade side 16 and accommodates the blades 17 and 19, the blade tip is retracted inward from the distal end portion of the case 3, but the connecting portion 5. It is near. For this reason, even if a force is applied to open the pair of hooks 13 and 15 by placing a finger on the finger rests 29 and 31, the cutting edge will come into contact with the inner wall surface of the case 3 near the connecting part 5. A large moment for opening 3 is not generated. Since the vicinity of the rear end portion that is the end portion of the case 3 to be opened and closed is suppressed by the claw portions 37 and 39 of the finger hook portions 29 and 31, the case 3 can be opened even if a force that is opened by the blade edge is applied to the case 3. I can't. That is, the case 3 functions to accommodate the blades 17 and 19 and suppress the opening thereof when in the forward position.

  In the vicinity of the rear end of the case 3, projections 55 and 57 that are locked to the claw portions 37 and 39 are formed in order to prevent the case 3 from moving forward further toward the cutting edge and coming out of the blades 17 and 19. ing. The protrusions 55 and 57 correspond to a specific example of the first locking portion of the present invention, and are formed on the outer surfaces of the bottom walls of the case members 7 and 9. The surfaces with which the claw portions 37 and 39 do not escape from the projection portions 55 and 57, that is, the rear end surfaces of the claw portions 37 and 39 and the front end surfaces of the projection portions 55 and 57 are both It is formed so as to be orthogonal to the sliding direction. Conversely, when the case 3 is mounted on the heel 1, the claw portions 37 and 39 are easily pushed open by the projections 55 and 57 (that is, the gaps 33 and 35 are increased) so that the case 3 can be easily mounted. In addition, the front end surfaces of the claw portions 37 and 39 and the rear end surfaces of the protrusions 55 and 57 are, for example, inclined with respect to the sliding direction of the case 3 or have a curved surface with an arcuate cross section. Since the finger-hanging portions 29 and 31 that form a kind of cantilever structure protruding from the trunk portions 25 and 27 can be elastically deformed to some extent, the protruding portions 55 and 57 that move from the blade side 16 to the gripping portion side 20 The claw portions 37 and 39 can be pushed open. Further, when the fingers of both hands, not the fingers of one hand, are hung on the finger hanging portions 29, 31 and a large force far exceeding the normal force when using the heel 1 is applied in the opening direction, the claw portions 37, 39 and The gaps 33 and 35 between the trunk portions 25 and 27 are opened, the locking by the claw portions 37 and 39 can be released, and the attached case 3 can be removed from the cage 1. Thus, the case 3 can be removed from the bag 1 by performing a special operation.

  Conversely, in order to prevent the case 3 from retreating unintentionally from the advance position on the blade side 16, the leaf spring 41 is provided on the trunk portion 25 as described above. As illustrated in the cross-sectional view of FIG. 4B, the leaf spring 41 locks the case 3 in the forward position by the front end of the leaf spring 41 facing the rear end surface of the case 3. In order to ensure a wide surface for receiving the front end of the leaf spring 41, projecting portions 63, 65, 67, and 69 that stand upright from the side walls are formed at the rear end portions of the pair of case members 7 and 9 (see FIG. 3). The four projecting portions 63, 65, 67, 69 are provided so that the orientation of the case 3 can be selected when the case 3 is attached to the bag 1, and symmetry is ensured in consideration of design. It is to do. It is also possible to provide the leaf springs 41 at a plurality of locations.

  Near the rear end of the case 3, other protrusions 59 and 61 that are locked to the claw portions 37 and 39 are formed. The protrusions 59 and 61 correspond to a specific example of the second locking portion of the present invention, and are formed on the outer surfaces of the bottom walls of the case members 7 and 9. The surfaces of the protrusions 59 and 61 are, for example, curved surfaces having a cross-sectional arc shape. Therefore, the nail | claw parts 37 and 39 can be pushed open by pinching the case 3 with a finger | toe and pushing back with a certain amount of force or more, and the latching by the nail | claw parts 37 and 39 can be cancelled | released. As described above, even if the leaf spring 41 is not provided, the case 3 can maintain the forward position by the protrusions 59 and 61. On the other hand, the leaf spring 41 causes the case 3 to move backward even when a force stronger than the force for releasing the locking state between the protrusions 59 and 61 and the claw portions 37 and 39 is applied to the case 3. To prevent. Further, the protrusions 59 and 61 also function to push and spread the claw portions 37 and 39 when the case 3 is advanced from the retracted position to the advanced position. When the case 3 reaches the advanced position, the claw portions 37 and 39 return to the original state. Accordingly, the finger that operates to move the case 3 forward is transmitted with a feeling of resistance by the claw portions 37 and 39 and a feeling that the resistance is canceled when the advance position is reached. Thereby, the user can recognize that the case 3 has correctly reached the forward position.

  FIG. 5 is an external perspective view showing the form of the case-attached scissors 101 when the case 3 is in a position retracted to the gripping part side 20 of the scissors 1. FIG. 6 is a view showing the structure of the case-attached scissors 101 when the case 3 is in the retracted position. FIG. 6A is a plan view of the case-attached scissors 101 including a cross-sectional view of the case 3. ) Is a cross-sectional view of a part of the case 101 with a case taken along the line D-D. As illustrated in FIGS. 5 and 6, when the case 3 is in the retracted position, the connecting portion 5 of the case 3 overlaps the rotating shaft 11 of the basket 1. Therefore, the pair of case members 7 and 9 can be opened and closed together with the pair of collar pieces 13 and 15. In order to prevent the opening blades 17 and 19 from interfering with the case 3, slit-shaped cuts 111 and 112 are formed at the tip of the case 3 (see also FIG. 4). The notches 111 and 112 are formed in the bottom walls of the pair of case members 7 and 9 to a certain depth from the tip portions.

  When in the retracted position, the pair of case members 7, 9 cover the trunk portions 25, 27, so that the user can move their fingers into the cavities 71, 73 formed by the case members 7, 9 and the finger hooks 29, 31. To open and close the basket 1. Thus, when the case 3 is in the retracted position, the case members 7 and 9 directly receive the force of the user's fingers instead of the trunk portions 25 and 27. That is, the case 3 forms part of the grips 21 and 23 when in the retracted position. Even when the case 3 is displaced forward from the retracted position, the case 3 is free to move in the closing direction, and there is nothing that prevents the movement. For this reason, unlike the prior art described in Patent Document 2, the case 3 is not damaged by the gripping force for closing the bag 1.

  As illustrated in FIGS. 5 and 6, the case members 7, 9 have a finger-hanging portion so that the contours of the cavities 71, 73 are curved smoothly connecting the case members 7, 9 to the finger-hanging portions 29, 31. Plate-like projections 75, 77, 79, 81, 83, 85, 87, 89 are formed so as to sandwich 29, 31. As a result, the contours of the cavities 71 and 73 are easily adapted to the user's finger. In the example of FIGS. 5 and 6, the plate-like protrusions 75, 77, 79, 81, 83, 85, 87, 89 are formed as extensions of the side walls of the case members 7, 9.

  As illustrated in FIG. 6B, when the case 3 is in the retracted position, the leaf spring 41 falls down and is accommodated in a groove-like recess 43 formed on the surface of the trunk portion 25. Thus, since the clearance gap which accommodates the fallen leaf | plate spring 41 is formed between the trunk | casing part 25 to which the case 3 and the leaf | plate spring 41 are attached, the leaf | plate spring 41 is fallen down and case 3 Can be slid from the forward position to the backward position.

  7A and 7B are views showing the structure of a bag with a case according to another embodiment of the present invention, wherein FIG. 7A is an external perspective view, and FIG. 7B is a partial cross-sectional view. In the case-equipped saddle 102, a recess 91 capable of accommodating the tip of the leaf spring 41 is formed on the rear end surface of the case 3 facing the leaf spring 41. As a result, even when an excessive compressive force is applied to the leaf spring 41, the tip end portion of the leaf spring 41 can be stopped in the recess 91 and prevented from jumping off the rear end surface of the case 3. In the example of FIG. 7, the ceiling portion of the recess 91 corresponds to a specific example of the spring restraining portion of the present invention that restrains the tip spring of the leaf spring 41 from jumping up. Instead of forming the recess 91, a protrusion that suppresses jumping of the tip of the leaf spring 41 may be formed on the rear end surface of the case 3. In this case, the protrusion corresponds to the spring holding portion of the present invention.

  FIG. 8 is an external perspective view of a case included in a bag with a case according to still another embodiment of the present invention. In the case 93 according to this embodiment, a restraining member 95 that suppresses lifting of the other side wall is formed on one side wall of the pair of case members 97 and 99. In the example of FIG. 8, the holding member 95 has a plate shape. As illustrated in FIG. 6, when the case 3 is in the retracted position, the leaf spring 41 exerts a pressing force that pushes up the one case member 7. As a result, a step may occur between the side walls of the pair of case members 7 and 9. That is, a kind of twist may occur between the case members 7 and 9. The restraining member 95 illustrated in FIG. 8 functions to restrain the case member 97 from floating with respect to the case member 99 and to align the side walls flush with each other.

  Only one of the protrusions 55 and 57 illustrated in FIGS. 4 and 6 may be provided. Similarly, only one of the protrusions 59 and 61 may be provided. The beam spring of the present invention takes various forms such as a metal wire like a piano wire, a plastic rod formed integrally with the trunk portion 25, as well as the illustrated leaf spring 41. obtain.

The bag with a case of Claim 1 which has a part.   The case is engaged with at least one of the pair of gaps so as to be releasable by an elastic restoring force of the corresponding finger-hanging portion so that the case does not move backward from the position advanced to the blade side to the gripping portion side. The scissors with a case according to claim 1 or 2, having a second locking portion. A beam-like spring provided in the form of a cantilever elastically bent and deformed on at least one of the pair of saddle pieces, wherein the case is moved from the position advanced to the blade side. A beam-like spring that is locked so as not to move backward toward the gripping portion;
The beam-like springs are fixed to the corresponding trunk portions so that the distal ends thereof are directed to the rotation shafts along the outer surfaces of the corresponding trunk portions, and the case is fixed to the blade. When it is in the position advanced to the side of the case, it springs up by an elastic restoring force so that the tip is opposed to the end surface of the case on the gripping part side, and the user presses the beam spring with a finger, 4. The beam-like spring is fallen down and fits in a gap between the case and the corresponding trunk portion while lying down, thereby allowing the case to slide toward the gripping portion. 5. A bag with a case as described in any of the above.   The case is provided with a spring restraining portion for restraining the tip of the beam-like spring so as to prevent the tip from coming off from the end surface of the case and further jumping to the end surface on the gripping portion side where the tip of the beam spring is opposed. The bag with a case of Claim 4 which has these.   The saddle with a case according to claim 4 or 5, wherein the trunk portion of the at least one of the pair of flange pieces has a concave portion that accommodates the fallen beam spring.   7. The case according to claim 4, wherein the case has a restraining member for restraining one of the pair of case members on the other side so as to restrain the pair of case members from being twisted with each other by the pressing force of the beam-shaped spring. A bag with a case described in any one of the above.   When the case is in the position retracted toward the grip portion, a cavity for inserting a finger is formed on the inner side together with the finger hook portion of the pair of hooks, and the outline of the cavity is hooked from the case. The hook with a case according to any one of claims 1 to 7, further comprising a plate-like protrusion that faces the finger hook and sandwiches the finger hook so as to be smoothly connected to a portion.
