[0013] Hereinafter, an embodiment of a punch assisting tool and a punch with an assisting tool according to the present invention will be described by way of example with reference to the drawings. In each drawing, the same reference numerals are used to designate the same components.

[0014] 1 is a diagram showing a punch with an assisting tool as one embodiment of the punch with an assisting tool according to the present invention, comprising a punch assisting tool 100 as a first embodiment of the punch assisting tool according to the present invention, and a punch 200. The punch assisting tool 100 comprises an assisting tool base 10, a handle 20, and an alarm unit 30. The punch assisting tool 100 may further comprise a container 40.

[0015] The punch auxiliary tool 100 can be fitted with the punch 200 and can assist in the operation of the punch 200. More specifically, when the punch 200 is supported by the auxiliary tool base 10, the handle 20 is rotated relative to the auxiliary tool base 10 to press an operating part 210 arranged in the center of the punch 200. When the operating part 210 is pressed, a pattern is cut out in the sheet to be punched 1000 inserted in the slit 250 of the punch 200 by the cutting blade of the punch 200. The cut piece 1100 (see FIG. 8 ) cut out by the punch 200 may drop and be stored in the container 40.

[0016] The auxiliary tool base 10 is configured to be able to support the punch 200. More specifically, the auxiliary tool base 10 of this embodiment includes a base body part 12 having a lower surface that can be placed on a horizontal surface such as the top surface of a desk, and two arm parts 11 that protrude from the upper surface side of the base body part 12 and are arranged opposite each other. The upper surface of the base body part 12 of this embodiment is provided with a positioning part 12a that can position the punch 200. The positioning part 12a of this embodiment is a recess that can accommodate the punch 200, but the form of the positioning part 12a is not particularly limited. In this way, the auxiliary tool base 10 of this embodiment can support the punch 200 by arranging the punch 200 in the positioning part 12a on the upper surface of the base body part 12.

[0017] The two arm portions 11 in this embodiment are arranged facing each other in the horizontal direction with the lower surface of the base main body portion 12 placed on a horizontal surface such as the top surface of a desk (hereinafter, sometimes simply referred to as the "used state of the punch auxiliary tool 100"). The two arm portions 11 in this embodiment extend in directions inclined relative to the vertical and horizontal directions when the punch auxiliary tool 100 is in the used state. However, the extending direction of the arm portions 11 is not limited to the direction in this embodiment.

[0018] When the punch auxiliary tool 100 is in use, the punch 200 is supported by the auxiliary tool base 10 so that it is supported at a position vertically above a horizontal plane such as the top surface of a desk on which the auxiliary tool base 10 is placed. Therefore, the punch 200 is located above the horizontal plane compared to when the punch 200 is used alone and placed on a horizontal surface such as the top surface of a desk. Therefore, the sheet to be punched 1000 can be easily inserted into the slit 250 extending horizontally in the punch 200 supported by the auxiliary tool base 10.

[0019] The handle 20 is rotatably attached to the assisting tool base 10. More specifically, the handle 20 of this embodiment is rotatably supported by the distal ends of the two arm sections 11 of the assisting tool base 10. The handle 20 of this embodiment has a substantially rectangular plate-like outer shape, and is attached to the distal ends of the arm sections 11 via a rotation shaft 25 provided at one end, i.e., the base end.

[0020] As described above, since the base end of the handle 20 is pivotally supported by the tip ends of the two arms 11, a gap is formed between the base body 12 of the assisting tool base 10 and the base end of the handle 20. The punch 200 is inserted into this gap, and is positioned at the position of the gap in a positioning portion 12a formed on the upper surface of the base body 12.

[0021] Moreover, the handle 20 can press the operation part 210 of the punch 200 supported by the aid base 10 by rotating relative to the aid base 10. Specifically, the handle 20 of this embodiment includes a protruding pressing part 21 (see Figs. 5 to 7) that protrudes toward the base body part 12 near the base end part. The protruding pressing part 21 of the handle 20 is configured so that the facing distance between the handle 20 and the base body part 12 can be changed by rotating the handle 20. Therefore, the protruding pressing part 21 of the handle 20 can press the operation part 210 of the punch 200 arranged at the positioning part 12a of the base body part 12 by rotating the handle 20 relative to the aid base 10.

[0022] Furthermore, the handle 20 of this embodiment is provided with a protruding portion 22 that protrudes toward the base body portion 12 near the tip end on the opposite side to the base end and is capable of coming into contact with the second sensor 32.

[0023] In the punch assist tool 100, when the user operates the vicinity of the tip of the handle 20, a large moment is generated in the handle 20. Therefore, by operating the handle 20 of the punch assist tool 100 and pressing the operating part 210 of the punch 200 via the handle 20, the user can press down the operating part 210 with a smaller force than when pressing the operating part 210 of the punch 200 directly. This allows the user to easily cut out a pattern or the like in the sheet 1000 to be punched.

[0024] 2 to 4 are diagrams showing three types of punches 200L, 200M, and 200S that can be used in the punch auxiliary tool 100 of this embodiment. The punch auxiliary tool 100 of this embodiment is configured to be able to switch between any of the three types of punches 200L, 200M, and 200S shown in FIGS. 2 to 4 as the punch 200. The three types of punches 200L, 200M, and 200S shown in FIGS. 2 to 4 are punches 200 that differ in at least one of shape and size. Specifically, the punches 200L, 200M, and 200S shown in FIGS. 2 to 4 have different cutout diameters for the punched sheet 1000, and therefore have different outer shapes. More specifically, the punch 200L shown in FIG. 2 is the largest, and the punch 200S shown in FIG. 4 is the smallest. That is, the punches 200L, 200M, and 200S shown in Figures 2 to 4 have a size relationship of "punch 200L>punch 200M>punch 200S". Hereinafter, in this embodiment, for convenience of explanation, the punch 200L shown in Figure 2 will be described as "large punch 200L", the punch 200M shown in Figure 3 will be described as "medium punch 200M", and the punch 200S shown in Figure 4 will be described as "small punch 200S". Note that when there is no particular distinction between the large punch 200L, the medium punch 200M, and the small punch 200S, they will simply be described as "punch 200".

[0025] As shown in Fig. 2, the large punch 200L consists only of the main body 220L. In other words, unlike the medium punch 200M and the small punch 200S, the large punch 200L does not include a base portion. The large punch 200L has a front-rear circular shape in a plan view seen from a direction perpendicular to the upper surface of the main body 220L. A slit 250 is formed slightly above the lower surface of the main body 220L, extending horizontally and opening to the side.

[0026] The main body 220L includes an operating unit 210L. The operating unit 210L is disposed in the center of the upper surface of the main body 220L. The operating unit 210L is connected to a cutting blade. The cutting blade has a shape corresponding to the pattern to be cut out in the sheet 1000 to be punched. When the operating unit 210L is pressed down, the cutting blade cuts out the pattern in the sheet 1000 to be punched. The operating unit 210L is biased upward by a spring. Therefore, when the operating unit 210L is not pressed down by an external force, the operating unit 210L protrudes from the upper surface of the main body 220L due to the bias. However, the operating unit 210L is not limited to a configuration protruding from the upper surface of the main body 220L, and may be configured to be flush with the upper surface of the main body 220L, for example.

[0027] As shown in FIG. 3, the medium punch 200M is composed of a main body 220M and a base 230M. The main body 220M is square in plan view from a direction perpendicular to the top surface of the main body 220M. The main body 220M is smaller than the main body 220L of the large punch 200L. The main body 220M includes an operating section 210M. The base 230M is formed with a recess 260M capable of accommodating the main body 220M. In other words, the recess 260M of the base 230M supports the main body 220M. In addition, the base 230M is formed with a through hole 240M near each of the two front corners. As will be described later, when the auxiliary tool base 10 supports the medium punch 200M (see FIG. 6), the position of the through hole 240M on the front right side corresponds to the position of the limit switch 33.

[0028] As shown in FIG. 4, the small punch 200S is composed of a main body 220S and a base 230S. The main body 220S is square in plan view from a direction perpendicular to the top surface of the main body 220S. The main body 220S is smaller than the main body 220M of the middle punch 200M. The main body 220S includes an operating section 210S. The base 230S is formed with a recess 260S capable of accommodating the main body 220S. In other words, the recess 260S of the base 230S supports the main body 220S. In addition, the base 230S does not have a through hole at the same position as the through hole 240M of the base 230M of the middle punch 200M.

[0029] Fig. 5 is a diagram showing the position of the handle 20 when the large punch 200L shown in Fig. 2 is set in the punch auxiliary tool 100 and cutting out a pattern or the like into the sheet to be punched 1000 (see Fig. 1) is completed. Fig. 6 is a diagram showing the position of the handle 20 when the medium punch 200M shown in Fig. 3 is set in the punch auxiliary tool 100 and cutting out a pattern or the like into the sheet to be punched 1000 (see Fig. 1) is completed. Fig. 7 is a diagram showing the position of the handle 20 when the small punch 200S shown in Fig. 4 is set in the punch auxiliary tool 100 and cutting out a pattern or the like into the sheet to be punched 1000 (see Fig. 1) is completed.

[0030] As shown in Fig. 5 and Fig. 7, when the auxiliary tool base 10 supports the large punch 200L or the small punch 200S, the handle 20 is fully tilted to complete cutting out the pattern or the like into the sheet 1000 to be punched. On the other hand, as shown in Fig. 6, when the auxiliary tool base 10 supports the medium punch 200M, the handle 20 is tilted to a certain extent (in Fig. 6, the handle 20 is slightly facing upward from the horizontal direction), and cutting out the pattern or the like into the sheet 1000 to be punched is completed. In other words, the position of the handle 20 at which the punch 200 completes cutting out varies depending on the type of punch 200 that differs in at least one of the shape and size. More specifically, the length l1 and width w1 of the main body 220L of the large punch 200L, the length l2 and width w2 of the main body 220M of the medium punch 200M, and the length l3 and width w3 of the main body 220S of the small punch 200S are all different. In addition, when the body of the punch is rounded, for example, when the body is circular in plan view, the diameter of the circle corresponds to the width and length. The height of the large punch 200L (the height of the body 220L), the height of the medium punch 200M in a state where the body 220M and the base 230M are combined, and the height of the small punch 200S in a state where the body 220S and the base 230S are combined may be different from each other, or two or more of these may be equal to each other.

[0031] The notification unit 30 can notify the outside that the cutting by the punch 200 has been completed, depending on the type of punch 200 that differs in at least one of the shape and size.

[0032] The notification unit 30 may include a light-emitting unit such as an LED 35. The notification unit 30 may light up a light-emitting unit such as the LED 35 to notify the outside that the cutting out by the punch 200 has been completed by light. The notification unit 30 may notify the outside that the cutting out by the punch 200 has been completed by sound using a speaker or the like.

[0033] The notification unit 30 of the present embodiment includes a first sensor 31 and a second sensor 32. The notification unit 30 can notify an outside party that cutting by the punch 200 has been completed based on the detection results of the first sensor 31 and the second sensor 32, depending on the type of punch 200 that differs in at least one of the shape and size.

[0034] Specifically, the first sensor 31 of this embodiment is a contact sensor that is attached to the arm portion 11 of the support base 10 and can detect the contact of the handle 20. As shown in FIG. 9, the contact sensor as the first sensor 31 of this embodiment is arranged so as to protrude to the side of the arm portion 11. The contact sensor as the first sensor 31 of this embodiment contacts the side of the handle 20 when the handle 20 rotates relative to the support base 10 and reaches a predetermined position. In this embodiment, the handle 20 is configured to contact the first sensor 31 at the position of the handle 20 shown in FIG. 6, that is, the position of the handle 20 in a state in which the punching into the punched sheet 1000 (see FIG. 1) is completed using the middle punch 200M. The notification unit 30 of this embodiment notifies the outside by light, sound, etc. when the handle 20 is detected by the first sensor 31.

[0035] The second sensor 32 of this embodiment is a contact sensor that is attached to the upper surface of the base body 12 of the support tool base 10 and can detect the contact of the handle 20. The contact sensor as the second sensor 32 of this embodiment contacts the protruding portion 22 of the handle 20 when the handle 20 rotates relative to the support tool base 10 and the tip of the handle 20 approaches the upper surface of the base body 12. In this embodiment, the handle 20 is configured to contact the second sensor 32 at the position of the handle 20 shown in Figs. 5 and 7, that is, the position of the handle 20 in a state where the large punch 200L and the small punch 200S are used to complete cutting into the punched sheet 1000 (see Fig. 1). When the handle 20 is detected by the second sensor 32, the notification unit 30 of this embodiment notifies the outside by light, sound, or the like.

[0036] As described above, the notification unit 30 of the present embodiment includes contact sensors as the first sensor 31 and the second sensor 32, but is not limited to this configuration, and one or both of the first sensor 31 and the second sensor 32 may be non-contact sensors. An example of a non-contact sensor is a magnetic sensor. The magnetic sensor as a non-contact sensor may be capable of detecting the position of the handle 20 by detecting a magnet arranged at a predetermined position of the handle 20. In other words, the notification unit 30 may include, as the first sensor 31 and the second sensor 32, a magnetic sensor as a non-contact sensor capable of detecting the position of each of the handles 20 in FIG. 5 to FIG. 7. Furthermore, the non-contact sensor is not limited to a magnetic sensor, and may be another non-contact sensor such as an optical sensor.

[0037] FIG. 10 is a top view of the punching aid 100 with the handle 20 omitted. As shown in FIG. 10, the notification unit 30 of this embodiment includes a limit switch 33. The limit switch 33 is arranged so that it can be pressed downward (in the depth direction of the paper of FIG. 10) when the punching aid 100 is in use. When the limit switch 33 is pressed, the first sensor 31 cannot detect the position of the handle 20. Note that the second sensor 32 of this embodiment is in a state in which it can detect the position of the handle 20 regardless of whether the limit switch 33 is pressed or not, but is not limited to this configuration. For example, the sensor capable of detecting the position of the handle 20 may be switched between the first sensor 31 and the second sensor 32 depending on whether the limit switch 33 is pressed or not.

[0038] 5 and 10, when the auxiliary tool base 10 supports the large punch 200L, the lower surface of the large punch 200L presses the limit switch 33. With reference to Figs. 6 and 10, when the auxiliary tool base 10 supports the medium punch 200M, the limit switch 33 is accommodated in the through hole 240M of the base portion 230M of the medium punch 200M. Therefore, the limit switch 33 is not pressed. With reference to Figs. 7 and 10, when the auxiliary tool base 10 supports the small punch 200S, the lower surface of the base portion 230S of the small punch 200S presses the limit switch 33.

[0039] As shown in Fig. 6, when the limit switch 33 is not pressed and the first sensor 31 (see Fig. 9) detects the handle 20, the notification unit 30 turns on the LED 35. In other words, the notification unit 30 can notify the outside when the middle punch 200M shown in Fig. 3 is set in the punch auxiliary tool 100 and cutting out a pattern or the like in the punched sheet 1000 (see Fig. 1) is completed.

[0040] 5 and 7, when the limit switch 33 is pressed and the second sensor 32 detects the handle 20, the notification unit 30 turns on the LED 35. That is, the notification unit 30 can notify the outside when either the large punch 200L or the small punch 200S shown in FIGS. 2 and 4 is set in the punch auxiliary tool 100 and cutting out a pattern or the like in the punched sheet 1000 (see FIG. 1) is completed. Since the limit switch 33 is pressed, the first sensor 31 is in a state where it does not detect contact with the handle 20 even if it comes into contact with the handle 20. Therefore, even if the handle 20 passes the position shown in FIG. 6 while rotating to the position shown in FIGS. 5 and 7, the LED 35 does not turn on at that time.

[0041] In this way, the punch assist tool 100 can switch the position of the handle 20 that the notification unit 30 notifies to the outside depending on the type of punch 200 (in this embodiment, the size of the punch 200) that differs in at least one of the shape and size.

[0042] So far, a configuration has been described in which the notification unit 30 identifies the type of punch 200 that differs in at least one of the shape and size by the limit switch 33. However, the notification unit may also identify the type of punch 200 by other configurations. For example, a laser, a camera, or the like may measure the shape or size of the punch 200. The size of the punch 200 may be identified by measuring the weight of the punch 200.

[0043] In this way, the notification unit 30 notifies the outside that the cutting out by the punch 200 has been completed in accordance with the type of the punch 200. Therefore, the user can immediately recognize that the cutting out by the punch 200 has been completed regardless of the type of the punch 200 used. Therefore, the user will not perform unnecessary operations after the cutting out by the punch 200 has been completed.

[0044] The handle 20 can be easily rotated with respect to the auxiliary tool base 10, for example, when the rotation resistance of the handle 20 with respect to the auxiliary tool base 10 is small. In this respect, the operability of the user can be improved. However, if the rotation resistance of the handle 20 with respect to the auxiliary tool base 10 is excessively small, for example, when carrying the handle 20, the handle 20 may rotate unintentionally with respect to the auxiliary tool base 10 due to its own weight or an external impact, which may result in a decrease in operability. In addition, if the user is not accustomed to operating the handle 20, the handle 20 may rotate at a large angular velocity by applying excessive force to the handle 20. Therefore, for example, the handle 20 may rotate in a direction away from the operating part 210 of the punch 200 (in a direction in which the pressing force is weakened), and the handle 20 may collide with the top surface of a desk on which the punch auxiliary tool 100 is placed. A loud noise is generated at the time of the collision. This may also damage the punch auxiliary tool 100.

[0045] Therefore, as shown in FIG. 9, the punch assist tool 100 may further include a maintaining mechanism 50 capable of maintaining the position of the handle 20 relative to the assist tool base 10. The maintaining mechanism 50 may be configured to include elastic bodies 51, such as two springs, wound around both ends of the rotation shaft 25 of the handle 20. The elastic bodies 51 press the handle 20 toward the arm portion 11 of the assist tool base 10. This pressing increases the frictional resistance between the handle 20 and the arm portion 11, making it easier to maintain the position of the handle 20 relative to the assist tool base 10. Therefore, unintended rotation of the handle 20 relative to the assist tool base 10 can be suppressed.

[0046] 1, when the punch assist tool 100 is in use, a container 40 that can be attached to and detached from the assist tool base 10 may be placed below the positioning portion 12a where the punch 200 is placed. As shown in FIG. 8, the user can easily collect the cut piece 1100 cut out by the punch 200 from the container 40.

[0047] The container 40 may be box-shaped. As shown in Fig. 1, the height of the container 40 may be lower than the base main body 12 of the aid base 10, and the container 40 may be configured to be able to be arranged below the positioning portion 12a. The container 40 may be attached to and detached from the aid base 10 in the horizontal direction from the vicinity of the punch 200 in a plan view of the punch aid 100. The container 40 may be formed with a handle 41. [Explanation of symbols]
