Description

Technical Field

[0001] The present invention relates to scissors with a cutter function that are preferably used in offices, homes, and the like.

Background Art

[0002] Conventionally, there is a well-known scissors that opens and closes a first blade part and a second blade part having blades to cut an object to be cut disposed between the two blades, that is, from an open posture in which the blade lines of the two blades are exposed to a closed posture in which the blade lines of the two blades are not exposed, and cuts the object to be cut disposed between the two blades.

[0003] Furthermore, there has been proposed a scissors that operates the two blades beyond the closed posture from the open posture, and at least a part of the blade line of the blade of at least the first blade part is exposed on the blade peak side of the second blade part, and can also be used as a cutter (see, for example, Patent Document 1).

[0004] By the way, the scissors described in Patent Document 1 have a mode switching mechanism using an actuator provided on the handle, and by sliding the actuator, the mode of using it as a normal scissors and the mode of using it as a cutter are switched.

[0005] Here, there is a demand to enable switching between the mode of using it as a normal scissors and the mode of using it as a cutter, even in scissors other than the mode having a finger hook on the handle as described in Patent Document 1.

[0006] However, there may not be enough space on the handle side to provide the above-described mode switching mechanism, and a configuration for realizing the mode of using it as a cutter in such scissors is required.

[Modes for carrying out the invention]

[0020] One embodiment of the present invention is described below with reference to Figures 1 to 9.

[0021] In this embodiment, the scissors S with a cutter function has a scissor body B having first and second blades H1 and H2 supported by a case A which is a support.

[0022] This pair of scissors with a cutter function S comprises a case A and a pair of scissors B supported by case A.

[0023] The scissors body B is configured to slide in the front-rear direction relative to case A so that it can take on three positions: a first position (P) in which the first blade H1 and the second blade H2 can be opened and closed to cut an object to be cut between the first and second blades H1 and H2; a second position (Q) in which the tip portion H1a of the first blade H1 is exposed to the spine H2x side of the second blade H2, allowing the tip portion H1a to be used as a cutter blade; and a third position (R) in which the first and second blades H1 and H2 are retracted into case A. Here, the second position (Q) is set after the first position (P), and the third position (R) is set even further after the second position (Q).

[0024] The following details the components of the scissors S.

[0025] Case A is made of synthetic resin. Case A comprises left and right side walls a1, a bottom wall a2 connecting the lower ends of the left and right side walls a1, a rear wall a3 connecting the rear ends of the left and right side walls a1, and a front upper wall a4 and a rear upper wall a5 connecting the upper ends of the left and right side walls a1. Inside Case A, there is a storage space sp that can accommodate at least a portion of the scissor body B, including a part of the moving blade operating section 42 which will be described later.

[0026] The front of case A has a front opening k1 that opens forward, connecting the storage space sp with the outside space. The top of case A has an upper opening k2 that opens upward, connecting the storage space sp with the outside space. The front opening k1 is sized so that the first and second blades H1 and H2 can pass through, and so that the moving blade body 4 can intersect with the stationary blade body 3 when the scissor body B is in the first position (P) (so that the first and second blades H1 and H2 can open). The upper opening k2 extends in the front-rear direction, and is set to have approximately the same left-right width dimension from the front end to the rear end so that the moving blade operating part 42 can move in the front-rear direction within the upper opening k2. The upper opening k2 is sized so that the moving blade operating part 42 can move back and forth in the front-rear direction. The rear lower end of case A is provided with a hole k3 for inserting a string or the like.

[0027] Case A is formed by connecting a left case member 1 and a right case member 2, which have a roughly left-right split structure.

[0028] In this embodiment, the scissors S are manufactured by positioning the scissors body B on the inner surface of either the left case member 1 or the right case member 2, and then joining the other case member to the first case member.

[0029] Next, we will describe the left case component 1.

[0030] The left case member 1 is provided with a left guide portion 11 on its inner surface, which is a guide portion capable of guiding the movable blade operating portion 42 of the scissor body B in the front-rear and up-down directions relative to the case A. The left guide portion 11 has a groove shape into which the left protrusion e1 provided on the movable blade operating portion 42 can engage. The left guide portion 11 includes a vertical guide portion 11a that extends vertically so as to be able to guide the movable blade operating portion 42, which is in a first position (P) at its front end, in the up-down direction, a first front-rear guide portion 11b that extends substantially in a straight line while sloping downward and towards the rear from the lower end of the vertical guide portion 11a, and a second front-rear guide portion 11c that extends substantially in a straight line towards the rear from the rear end of the first front-rear guide portion 11b. The rear end portion 11be of the first front-rear guide portion 11b is set to have a wider vertical width than the other parts to allow for slight vertical movement of the moving blade operating portion 42 in order to smoothly lock or unlock the case A in the second position (Q). The rear end portion 11ce of the second front-rear guide portion 11c is also set to have a wider vertical width than the other parts to allow for slight vertical movement of the moving blade operating portion 42 in order to smoothly lock or unlock the case A in the third position (R). Furthermore, a stopper 11x is provided projecting upward from the lower edge of the boundary between the vertical guide portion 11a and the first front-rear guide portion 11b, thereby preventing the scissor body B from retracting from the first position (P) to the second position (Q) during use as scissors.

[0031] Furthermore, the left case member 1 is provided with a left guide groove 12 that extends linearly in the front-rear direction at a position below the left guide portion 11 on its inner surface. The left guide groove 12 is a portion that can engage with the left guided projection g1 provided on the stationary blade operating portion 32 of the scissor body B. By engaging the left guided projection g1 on the stationary blade operating portion 32 with the left guide groove 12, the stationary blade body 3 can slide stably in the front-rear direction relative to the case A.

[0032] Next, we will describe the right case component 2 in detail.

[0033] The inner surface of the right case member 2 is provided with a right guide portion 21, which is a guide portion capable of guiding the movable blade operating portion 42 of the scissor body B in the front-rear and up-down directions relative to the case A. The right guide portion 21 has a groove shape into which the right-side protrusion e2 provided on the movable blade operating portion 42 can engage. The right guide portion 21 includes a vertical guide portion 21a that extends vertically so as to be able to guide the movable blade operating portion 42, which is in a first position (P) at its front end, in the up-down direction; a first front-rear guide portion 21b that extends substantially linearly from the lower end of the vertical guide portion 21a while sloping downward and towards the rear; and a second front-rear guide portion 21c that extends substantially linearly towards the rear from the rear end of the first front-rear guide portion 21b. The rear end portion 21be of the first front-rear guide portion 21b is set to have a wider vertical width than the other portions to allow for slight vertical movement of the moving blade operating portion 42 in order to smoothly lock or unlock the case A in the second position (Q). The rear end portion 21ce of the second front-rear guide portion 21c is also set to have a wider vertical width than the other portions to allow for slight vertical movement of the moving blade operating portion 42 in order to smoothly lock or unlock the case A in the third position (R). Furthermore, a stopper 21x is provided projecting upward from the lower edge of the boundary between the vertical guide portion 21a and the first front-rear guide portion 21b, thereby preventing the scissor body B from retracting from the first position (P) to the second position (Q) during use as scissors. The right guide portion 21 and the left guide portion 11 have a symmetrical shape. In other words, these left and right guide sections 11 and 21 are positioned so that they overlap when the scissors S with a cutter function is viewed from the side.

[0034] Furthermore, the right case member 2 is provided with a right guide groove 22 that extends linearly in the front-rear direction at a position below the right guide portion 21 on its inner surface. The right guide groove 22 is a portion that can engage with the right guided projection g2 provided on the stationary blade operating portion 32 of the scissor body B. By engaging the right guided projection g2 on the stationary blade operating portion 32 with the right guide groove 22, the stationary blade body 3 can slide stably in the front-rear direction relative to the case A.

[0035] The right case member 2 has an engaging projection 23 on the front end portion of the part that constitutes the rear upper wall a5, which can engage with the L-shaped locking projection e3 that protrudes from the rear end of the movable blade operating section 42. In this embodiment, the scissors body B is such that the rear locking projection e3 and the engaging projection 23 can engage in the third position (R). By engaging the rear locking projection e3 and the engaging projection 23, the forward movement of the scissors body B in the third position (R) can be locked.

[0036] Furthermore, in this case A, when the scissors S with a cutter function is used as a cutter, that is, when the scissors body is in the second position (Q), a guide means G is provided to guide the direction of travel of the first blade H1. This guide means G has first and second guide surfaces s1 and s2 that can be brought into contact with two adjacent surfaces, respectively. These first and second guide surfaces s1 and s2 are orthogonal. With the scissors body B positioned in the second position (Q), the first blade H1 is positioned near the line L0 where these first and second guide surfaces s1 and s2 intersect.

[0037] The scissors body B comprises a stationary blade body 3 having a first blade portion H1, a movable blade body 4 rotatably supported relative to the stationary blade body 3 and having a second blade portion H2, with a movable blade operating portion at the rear of the second blade portion H2, a pivot shaft 5 that rotatably connects the stationary blade body 3 and the movable blade body 4, and a coil spring 6 which is a biasing member that biases the first and second blade portions in the direction of opening.

[0038] The stationary blade body 3 is supported so as to be slidable in the front-rear direction relative to the case A. The stationary blade body 3 comprises a metal stationary blade member 31 having a first blade portion H1 at its front end, and a synthetic resin stationary blade operating portion 32 attached to the rear end of the stationary blade member 31 by insert molding.

[0039] The stationary blade operating section 32 is located behind the first blade section H1. On both sides of the lower part of the stationary blade operating section 32, there are left and right guided protrusions g1 and g2 that can engage with the left guide groove 12 and the right guide groove 22 provided in the case A.

[0040] The moving blade body 4 is supported so as to be rotatable relative to the stationary blade body 3 via a pivot member 5. The moving blade body 4 is supported so as to be slidable in the front-rear direction relative to the case A together with the stationary blade body 3, which is pivotally attached by the pivot member 5. The moving blade body 4 comprises a metal moving blade member 41 having a second blade portion H2 at its front, and a synthetic resin moving blade operating portion 42 attached to the rear end of the moving blade member 41 by insert molding.

[0041] The blade operating section 42 is located behind the second blade section H2. The blade operating section 42 comprises a blade operating section body 42a that is block-shaped and extends in the front-rear direction, with its upper surface being a contact surface m for the user's fingers to contact; a left protrusion e1 and a right protrusion e2 that protrude from the lower part of the front end of the blade operating section body 42a and engage with the left and right guide sections 11 and 21 provided on the case A; and a rear locking projection e3 that protrudes in an L-shape from the rear end of the blade operating section body 42a toward the rear and can engage with the engaging projection 23 provided on the case A. In addition, a finger-holding projection 42a1 for gripping fingers is provided on the upper surface of the blade operating section body 42a.

[0042] The stationary blade body 3 and the moving blade body 4 are connected by a pivot shaft 5 at the rear of the first and second blade sections H1 and H2 so that they can rotate relative to each other. In other words, the portion of the stationary blade body 3 between the first blade section H1 and the stationary blade operating section 32 and the portion of the moving blade body 4 between the second blade section H2 and the moving blade operating section 42 are pivotally connected by the pivot shaft 5.

[0043] The coil spring 6 is located behind the pivot shaft 5 and is disposed between the stationary blade body 3 and the moving blade body 4. The lower end of the coil spring 6 is supported (by a retainer 32x) on the front upper part of the stationary blade operating section 32, and the upper end is supported (by a retainer 42x) on the front lower part of the moving blade operating section 42. The coil spring 6 constantly provides a biasing force that allows the first blade portion H1 and the second blade portion H2 to rotate in the direction of opening, that is, in the direction of moving away from each other.

[0044] Next, we will describe the manner of use of these scissors with a cutter function S and the operation of each part.

[0045] When using these scissors with a cutter function S as scissors, the scissor body B is moved to the first position (P) at the front end via the movable blade operating part 42.

[0046] At this time, the protrusions e1 and e2 of the moving blade operating section 42 are engaged with the front ends of the left and right guide sections 11 and 21, respectively. More specifically, when no external force is applied, the protrusions e1 and e2 are engaged with the front ends of the first front-rear guide sections 11b and 21b and the upper ends of the vertical guide sections 11a and 21a.

[0047] Then, when the moving blade operating section 42 is brought closer to the stationary blade operating section 32, the protrusions e1 and e2 of the moving blade operating section 42 move downward while sliding against the scissor cutting operation guide groove, and the second blade section H2 moves upward.

[0048] Then, when the second blade H2 strikes the paper sheets to be cut, the paper sheets are sandwiched between the first blade H1 and the second blade H2, and the paper sheets are cut.

[0049] When using these scissors with a cutter function S as a cutter, the scissor body B is moved to the intermediate second position (Q) via the moving blade operating unit 42.

[0050] At this time, the blade operating section 42 is biased by the coil spring 6, and the left and right guided protrusions g1 and g2 engage with the rear ends 11be and 21be of the first front-rear directional guide sections 11b and 21b on the left and right guide sections 11 and 21, respectively. In this state, the movement of the scissor body B in the front-rear direction is restricted.

[0051] Furthermore, in this state, almost the entire second blade portion H2 is located within the blade width of the first blade portion H1 (the blade width w1 of the stationary blade body), and the cutting edge portion H1a of the first blade portion H1 is exposed to the spine H2x side of the second blade portion H2, so that the cutting edge portion H1a of the first blade portion H1 can be used as a cutter blade.

[0052] This pair of scissors with a cutter function S is configured to cut a rectangular box BX along its edge BXe by bringing the first and second guide surfaces s1 and s2 of the guide means G into contact with the two faces BXa and BXb that make up the edge BXe. More specifically, when the first and second guide surfaces s1 and s2 are brought into contact with the faces BXa and BXb adjacent to the edge BXe to be cut, respectively, the first blade H1 is positioned near the line L0 where the first and second guide surfaces s1 and s2 intersect, so that the cutting edge of the first blade H1 strikes the edge BXe to be cut or its vicinity.

[0053] On the other hand, when using these scissors with a cutter function S as a cutter to cut sheet-like paper, the area near the boundary between the lower wall a2 of the case A and the front opening k1, and the cutting edge portion H1a of the first blade H1, should be brought into contact with the paper to be cut.

[0054] When the scissors S with the cutter function are not in use, the scissor body B is moved to the third position (R) at the rear end via the movable blade operating unit 42.

[0055] At this time, the blade operating section 42 is biased by the coil spring 6, and the left and right guided protrusions g1 and g2 engage with the rear ends 11ce and 21ce of the second front-rear directional guide sections 11c and 21c of the left and right guide sections 11 and 21, respectively. In this state, the forward movement of the scissor body B is restricted, and almost the entire scissor body B, excluding the upper part of the blade operating section 42, remains housed in the case A.

[0056] Furthermore, when moving the scissor body B from the second position (Q) to another position, prior to sliding the blade operating unit 42, the blade operating unit 42 is pressed downward to release the engagement between the left and right guided protrusions g1 and g2 and the rear ends 11be and 21be of the first front-rear directional guide portions 11b and 21b on the left and right guide portions 11 and 21. Also, when moving the scissor body B from the third position (R) to another position, prior to sliding the blade operating unit 42, the blade operating unit 42 is pressed downward to release the engagement between the left and right guided protrusions g1 and g2 and the rear ends 11ce and 21ce of the second front-rear directional guide portions 11c and 21c on the left and right guide portions 11 and 21.

[0057] Here, Figure 1 is an overall perspective view showing the scissors with cutter function S of this embodiment with the scissor body B in the first position (P) and used as scissors. Figure 2 is a right side view showing the same configuration. Figure 3(a) is a top view, and Figure 3(b) is a bottom view. Figure 4 is a right side view showing the scissors with cutter function S with the scissor body B in the second position (Q) and used as a cutter. Figure 5 is a right side view showing the scissors with cutter function S with the scissor body B in the third position (R) and stored in case A. Note that in Figures 2, 4, and 5, the portion of the scissor body B stored in case A, the ribs formed on the outer circumference of the rear and lower part of the right case member 2, and the right guide part 21 are shown with dashed lines. Figure 6 is an exploded perspective view of the scissors with cutter function S from the upper right. Figure 7 is an exploded perspective view from the lower right. Figure 8 is an exploded perspective view from the upper left. Note that the coil spring 6 is omitted in Figures 6 to 8. Figure 9 is a cross-sectional view along line XX in Figure 4.

[0058] As described above, according to the configuration of this embodiment, the scissor body B is configured to be movable relative to the case A between a first position (P) and a second position (Q). Therefore, even if the movable blade operating unit 42 used as a handle is small, it is possible to switch between a mode for use as normal scissors and a mode for use as a cutter.

[0059] Furthermore, the scissor body B is configured to be movable relative to case A, not only between the first position (P) and the second position (Q) mentioned above, but also to a third position (R) in which the first and second blades H1 and H2 are retracted into case A. Therefore, when not in use, the blades H1 and H2 can be stored inside case A for safe transport.

[0060] Furthermore, since the scissor body B is supported so as to be slidable in the front-rear direction relative to the case A, and the second position (Q) is set after the first position (P), and the third position (R) is set after the second position (Q), the scissor body B can be easily switched between being stored in the case A, being used as a cutter, and being used as scissors by sliding the scissor body B.

[0061] Since the blade width w1 of the stationary blade 3 is made larger than the blade width w2 of the moving blade 4, or in other words, the blade width w2 of the moving blade 4 is made smaller than the blade width w1 of the stationary blade 3, the stroke required from the position where the cutting edges of the first and second blade sections H1 and H2 overlap to the position where the cutting edge portion H1a of the first blade section H1 is exposed on the backbone side H2x of the second blade section H2 can be reduced.

[0062] Guide portions 11 and 21 are provided on the inner surface of case A, which can guide the movable blade operating portion 42 in the front-rear and up-down directions relative to case A. Since the guide portions 11 and 21 are groove-shaped so that they can engage with the protrusions e1 and e2 provided on the movable blade operating portion 42, the direction of movement of the scissor body B relative to case A can be guided by slidably engaging the protrusions e1 and e2 provided on the outer surface of the movable blade operating portion 42 with the guide portions 11 and 21 provided on the inner surface of case A, and the required space can be reduced.

[0063] Since the guide sections 11 and 21 are provided on the left and right inner surfaces of case A, the scissor body B can be stably guided in the direction of movement relative to case A.

[0064] However, the present invention is not limited to the embodiments described above.

[0065] For example, in the embodiment described above, the support is a case, and the scissors body can be housed inside the case. However, the support may be configured to hold only the stationary blade operating part and the moving blade operating part of the scissors body, and the present invention may be applied to scissors with a cutter function in which the scissors body can move relative to each other only between a first position and a second position.

[0066] Furthermore, the positional relationship between the first position and the second position can be set arbitrarily. For example, the present invention may be applied to scissors with a cutter function in which the second position is in front of the first position, in other words, the scissor body in the first position can be moved to the second position by moving it toward the blade tip from the blade operating part.

[0067] Furthermore, although the above-described embodiment includes a biasing member that biases the first and second blades in the direction of opening, the present invention may also be applied to scissors with a cutter function that do not have such a biasing member.

[0068] In addition, in the above-described embodiment, a guide portion is provided on the inner surface of the support (case) that can guide the blade operating portion in the front-rear and up-down directions relative to the support (case). However, the guide portion may adopt any configuration as long as it can guide the relative movement of the scissor body between a first position and a second position relative to the support (case). For example, in the above-described embodiment, the guide portion is groove-shaped into which a protrusion provided on the blade operating portion can engage, but the guide portion may be rail-shaped into a protrusion that can engage with a recess provided on the blade operating portion.

[0069] Furthermore, in the above-described embodiment, when the scissor body is moved to the second position while being guided by the guide, the movable blade operating part is positioned so that the cutting edge portion of the first blade is exposed to the spine side of the second blade. However, for example, the scissor body may be configured to be movable to a predetermined intermediate position while being guided by the guide, and by applying operating force to an operating part such as a separately provided push button, the cutting edge portion of the first blade moves to the spine side of the second blade and the scissor body takes the second position.

[0070] Furthermore, various modifications are permitted as long as they do not impair the spirit of the present invention. [Explanation of Symbols]
