MODE FOR INVENTION

[0018] The present disclosure propose a tape cutter that includes a cutter body configured to release rolled tape accommodated therein to the outside through a release hole formed on a bottom thereof and configured to be able to cut the tape by having a blade, wherein the cutter body comprises a taping guide disposed downward at a front side adjacent to the release hole, configured to make the tape be released with a non-adhesive surface of the tape in contact with a rear thereof, and configured to rotate forward after holding in order to prevent injuries of a user and improve work efficiency because a worker can work even without turning a box of bending an arm when taping adjacent taping-target surfaces making a predetermined angle to each other.

[0019] The right range of the present disclosure is not limited to the following embodiments and the present disclosure may be changed in various ways by those skilled in the art without departing from the scope of the present disclosure.

[0020] Hereafter, a tape cutter of the present disclosure is described in detail with reference to FIGS. 1 to 9.

[0021] A tape cutter of the present disclosure, as shown in FIGS. 1 to 3, includes a cutter body A that releases rolled tape 10 accommodated therein to the outside and has a blade 120 that can cut the released tape 10.

[0022] The cutter body A may be formed in various shapes, and as shown in FIGS. 1 to 3, may have a structure for mounting rolled tape 10 therein and may have case shape that can come in contact with a taping-target object on the entirety or a portion of the bottom so that the tape 10 released and attached to the taping-target object can be pressed.

[0023] As a detailed example, the cutter body A may have an empty case shape being open on the bottom and a first side except for the front, in which a mount ring 151 on which the tape 10 can be fitted may be formed on a second side and an anti-separation ring 152 may be coupled to a side of the mount ring 151 to prevent the tape 10 fitted on the mount ring 151 from separating in one lateral direction.

[0024] The tape 10 accommodated inside the cutter body A can be released outside through the open bottom. A release hole 110 may be formed on the bottom of the cutter body A so that the release point can be specified. For example, the release hole 110, as shown in FIG. 3, may be formed between the bottom of the non-open front of the cutter body A and a release guide pin 140 disposed in the width direction of the cutter body A at a predetermined distance rearward from the bottom. Accordingly, the tape 10 fitted on and unwound from the mount ring 151 can be released outside through the release hole 110 defined by the bottom of the front of the cutter body A and the release guide pin 140. However, the release hole 110 may be formed in various shapes, depending on the shape of the cutter body A, and is not limited to the example described above.

[0025] The blade 120 provided at the cutter body A, as shown in FIGS. 1 to 3, may be disposed at the front end of the cutter body A, and not only may be integrated with the cutter body A, but may be formed detachably from the cutter body A so that it can be replaced. Further, though not shown, the blade 120 may be configured to be disposed inside the cutter body A and to protrude outside and cut the tape 10 by operation by a user.

[0026] In the present disclosure, the cutter body A has a taping guide 200 to be able to tape easily at once adjacent taping-target surfaces making a predetermined angle to each other. The predetermined angle means the angle between adjacent taping-target surfaces of a plurality of taping-target surfaces constituting a taping-target object. For example, when a taping-target object is a box, the angle between adjacent taping-target surfaces is generally 900 and it is assumed that the predetermined angle is 90 in the following description for the convenience of description, but it is not limited thereto and may mean an acute angle or an obtuse angle.

[0027] The taping guide 200, as shown in FIGS. 1 to 4, is disposed downward at the front side adjacent to the release hole 110, so the non-adhesive surface of the tape 10 that is released through the release hole 110 can come in contact with the rear of the taping guide 200. For example, as shown in FIG. 6, when the taping guide 200 is vertically positioned, the tape 10 released outside through the release hole 110 can be vertically released in contact with the rear of the taping guide 200.

[0028] The taping guide 200 disposed downward can be rotated forward and is configured to be held before it is rotated forward so that the tape 10 released outside and positioned on the rear of the taping guide can be attached to a taping-target surface. Holding of the taping guide 200 may be performed in various ways, and for example, the taping guide 200 may be configured to be elastically held.

[0029] To this end, the taping guide 200 may include a rotary shaft 210 and a taping guide member 220. As shown in FIGS. 1 to 5, the rotary shaft 210 may be disposed in the width direction of the cutter body A around the bottom adjacent to the release hole 110 inside the cutter body A, and the taping guide member 220 is coupled to the rotary shaft 210 and disposed downward and can be rotated forward together with the rotary shaft 210. As a detailed example, the taping guide member 220 is formed in a U-shape to be open upward and can be coupled at both ends to both ends of the rotary shaft 210 protruding from both sides of the cutter body A.

[0030] A locking protrusion 211 protruding in a direction in which it does not interfere with rotation of the taping guide member 220, that is, protruding forward may be formed on the rotary shaft 210. When a force that rotates forward the taping guide member 220 is applied, the holding protrusion 211 is locked, and then when a force over a predetermined level is applied in the same direction, the holding protrusion 211 can be unlocked.

[0031] To this end, for example, the cutter body A may include a holding unit 300 therein that elastically locks the locking protrusion 211 therein. The holding unit 300 may include a holder 310 that is, as shown in FIGS. 1 to 5, disposed such that an end portion thereof is positioned over an end portion of the locking protrusion 211 for elastic holding when the taping guide member 220 is positioned downward.

[0032] As a detailed example, as shown in FIG. 4, a holder mount 130 for installing the holder 310 may be provided inside the front of the cutter body A. The holder 310 is positioned and the holder mount 130 and faces rear, so the other portion excluding the front can protrude from the holder mount 130. A guide flange 311 may be formed on both sides of the front of the holder 310 so that the holder 310 in the holder mount 130 can be moved up and down without being pulled out, and movement passages 133 in which the guide flanges 311 can be accommodated may be formed in the up-down direction inside the holder mount 130.

[0033] The holding unit 300 may include a first holding spring 320 and a second holding spring 330 that apply elasticity to the holder 310 so that the locking protrusion 211 can be elastically locked through the holder 310. For example, as shown in FIGS. 4 and 5, a first spring installation channel 131 connected with the movement passages 133 may be formed between the movement passages 133 in which the guide flanges 311 on both sides of the holder 310 may be formed in the holder mount 130, and a first holding spring 320 may be provided such that a first end thereof is in contact with the top of the first spring installation channel 131 and a second end thereof is in contact with the top of the holder 310. Further, a second spring installation channel 132 may be formed forward from the bottom of the first spring installation channel 131 in the holder mount 130, and a second holding spring 330 may be provided such that a first end thereof is in contact with the front of the second spring installation channel 132 and a second end thereof is in contact with the front of the holder 310. In this configuration, the holder 310 should be able to move forward and backward so that elasticity of the second holding spring 330 can act, so the first spring installation channel 131 and the movement passages 133 may be formed such that the lower portion thereof are wider in the front-rear direction than the other portion. For example, the lower portions of the first spring installation channel 131 and the movement passages 133 may be formed such that the width in the front-rear direction gradually increases downward.

[0034] Accordingly, elasticity is applied downward to the holder 310 by the first holding spring 320 and elasticity is applied rearward to the holder 310 by the second holding spring 330. Since the guide flanges 311 of the holder 310 to which elasticity is applied by the first holding spring 320 and the second holding spring 330, as described above, are accommodated in the movement passages 133, the holder 310 is not separated out of the holder mount 130.

[0035] The process in which the locking protrusion 211 is elastically locked and unlocked in the present disclosure described above is described. As shown in FIG. 6, the end portion of the holder 310 protruding from the holder mount 130 is positioned adjacent o and over the end portion of the locking protrusion 211 when the taping guide member 220 is positioned downward. When a force that rotates the taping guide 200 forward is applied, the holder 310 is not moved until a force larger than the elasticity of the first holding spring 320 and the second holding spring 330 is applied, so the locking protrusion 211 is elastically locked.

[0036] Thereafter, when a force larger than the elasticity of the first holding spring 320 and the second holding spring 330 is applied, as shown in FIGS. 7 and 8, the end portion of the locking protrusion 211 pushes up the end portion of the holder 310 while pushing forward the end portion of the holder 310, whereby the locking protrusion 211 is unlocked from the holder 310. The bottom of the end portion of the holder 310 may be formed to be inclined upward toward the rear so that the locking protrusion 211 can be easily unlocked from the holder 310. That is, when a force over a predetermined level is applied, the end portion of the locking protrusion 211 positioned under the holder 310 slides on the inclined bottom of the end portion of the holder 310 while pushing up the end portion of the holder 310, whereby the locking protrusion 211 can be unlocked from the holder 310. Accordingly, as the locking protrusion 211 elastically locked to the holder 310 is unlocked, the taping guide 200 is rotated forward, as shown in FIG. 9.

[0037] In order that the taping guide 200 rotated forward can press the tape 10 attached to a taping-target surface, the portion, where the forwardly rotated taping guide 200 is positioned, of the bottom of the front of the cutter body A may be recessed upward. Accordingly, the taping guide 200 rotated forward and accommodated in the recessed portion of the bottom of the front of the cutter body A presses the tape 10 attached to a taping-target surface together with the non-recessed portion of the front of the cutter body A.

[0038] That is, according to the present disclosure, as shown in FIGS. 6 to 9, for adjacent taping-target surfaces making a predetermined angle to each other, when the cutter body A is moved to move over a second taping-target surface with the taping guide 200, which is positioned downward, positioned close to a first taping-target surface, the taping guide 200 is held, so the tape 10 is attached to the first taping-target surface. Further, as the cutter body A keeps being moved, the taping guide 200 is rotated forward, so the tape 10 is attached to the second taping-target surface without interference by the taping guide 200. Accordingly, a worker can tape adjacent taping-target surfaces even without turning a taping-target object or bending his/her arm, so it is possible to prevent injuries of a worker and improve work efficiency.

[0039] Meanwhile, the taping guide 200 can be returned to the initial position by elasticity after rotated forward so that the taping guide 200 rotated forward can display its function again.

[0040] For example, the taping guide 200 can be elastically returned by a return spring 230 disposed on the rotary shaft 210, as shown in FIGS. 4 and 5, and, in this configuration, the return spring 230 may be a torsion spring. In order that elasticity is applied by the return spring 230 that is a torsion spring, the return spring 230 may be wound on the rotary shaft 210 close to the second side of the cutter body A. Further, a first end protruding from the wound part of the return spring 230 may be fixed by a first spring fixing protrusion 212 protruding from the rotary shaft 210 and a second end protruding from the wound part may be fixed by a second spring fixing protrusion 160 protruding inward from the second side of the cutter body A.

[0041] Therefore, when the force pressing the tape 10 attached to a taping-target surface is removed, the taping guide 200 rotated forward is rotated rearward by elasticity of the return spring 230, whereby the taping guide 200 can be returned to be positioned downward.
