Description

Technical Field

[0001] The present invention relates to a box corner stapler, and more particularly to a box corner stapler that fixes the corner portion of a common box and presses the end portion of an iron core, and can minimize the protrusion of the iron core by double pulling a handle. Background Art

[0002] First, the conventional technology is described. Generally, a stapler is a stapler that uses A device used to bind multiple sheets of paper together using a shaped anvil.

[0003] The above-mentioned conventional stapler is formed by the following structure: a lower plate of a support disk that bends the anvil of the stapler is formed at the end of one side of the upper part; one end is hinged to the other side of the support disk formed with the lower plate and rotates, and an anvil storage portion is formed inside with an insertion space for inserting multiple anvils from a horizontal direction; one side is connected to the hinge and wrapped around the anvil storage portion, and when one side is selectively pressed, the upper plate of the anvil can be drawn out, thereby enabling multiple papers to be fixed.

[0004] However, the conventional staplers mentioned above are usually used to bundle overlapping sheets of paper. They are not only used for sheets of paper, but also for assembled boxes, where the overlapping portions can be easily fixed using a stapler or the like. However, the corner portions of the box are fixed by bolts and nuts made of synthetic resin. In order to fix the corner portions of the box, the ends are connected, and the portions protruding toward the ends are overlapped to form holes therebetween, and are fixed using the bolts and nuts.

[0005] Furthermore, conventional modular boxes have many inconveniences during assembly. Furthermore, if one of the bolts or nuts is damaged, it is not possible to purchase the bolts or nuts separately, and the entire modular box must be discarded, significantly reducing economic efficiency. Furthermore, when purchasing the modular box online or offline, if the bolts or nuts are missing or a defective product is found, the modular box cannot be used.

[0006] Therefore, this type of assembled box is formed with additional corner reinforcements to strengthen the corners and then fix them. However, this structure cannot be applied to all assembled boxes.

[0007] Therefore, Korean Patent Application No. 10-1508527 "Stapler" and Korean Publication No. 10-2010-0072120 "Stapler with Vertical and Angular Fixing Frame" have been disclosed in the past, but the above-mentioned problems have not been solved.

[0008] In addition, the Korean authorization number 10-2011344 applied for and authorized by the applicant, "A stapler for box corners and a method for fixing box corners using the stapler", is disclosed. However, when the iron core is nailed to the corner of the box, the protrusion of the end portion of the iron core folded inward causes the contents to be caught when the contents are put into the box, making it impossible to successfully complete the function of the box. In addition, there is a problem of reducing the aesthetic sense. Summary of the Invention

[0009] Technical issues

[0035] Hereinafter, with reference to the accompanying drawings, Figures 1 to 8 the preferred configurations and functions of the present invention for achieving the above object will be described.

[0036] First, before describing the present invention, a stapler authorized to the applicant will be described.

[0037] This stapler is formed of the following structure: a lower plate 100, which has a core support disk 110 formed at one end of the upper part for bending the core 201 of the stapler; a core storage part 200, which is formed of the following structure: one end is hinge-coupled to one side of the lower plate 100, and a plurality of cores are horizontally inserted therein, and a core discharge port for selectively discharging the inserted cores; a core pushing member for pushing the core 201; a fixing rod formed on the opposite side of the core pushing member; a first pushing elastic member having one side connected to the core pushing member and the other side connected to the fixing rod; an upper plate 300, one side of which is connected to the hinge and is formed above the core storage part 200, and a second pushing elastic member connected to one side of the core storage part 200 is formed therein. Among them, the core support disk is formed to gradually widen from the upper part to the lower part, and inclined surfaces are respectively formed on both upper side surfaces, and an insertion part extending downward from the end of the inclined surface is formed, and the outer shape of the part where the core discharge port of the core storage part 200 is formed corresponds to a part of the upper part of the core support disk 110 so as to accommodate a part of the upper part of the core support disk 110, and mutually different introduction spaces for introducing each surface of the assembled box are respectively formed between the core support disk 110 and the core storage part 200, and each different surface of the box is inserted into the respective introduction spaces, and then, opposite ends of the box are made to completely contact each other, and cores 201 are nailed into each surface to form the corners of the box.

[0038] The lower plate 100 substantially refers to the component of the lower part of the stapler, and a core support disk 110 of the stapler is formed at the upper end, and the side surface of the core support disk 110 is formed in a V-shape, and one inner side surface and another inner side surface of the assembled box are made to closely adhere to the inclined inclined surfaces, and the corners of the box are naturally and correctly formed by the part formed by the vertex of the upper part.

[0039] That is, the stapler is a technology for fixing the corner parts of a box, rather than fixing multiple sheets after overlapping them as in a conventional stapler. Therefore, different from the conventional assembly methods such as bolts and nuts, no additional components are required, and the corner parts of the box can be easily fixed only by one stapler, which provides convenience.

[0040] Furthermore, a stepped portion is formed integrally with the lower plate 100 or at a portion of the lower plate 100 where the core support plate 110 is located, so that the core support plate 110 can be inserted into the insertion portion and hung at the end, thereby enabling the core support plate 110 to be selectively inserted into and separated from the stepped portion.

[0041] Through the above-mentioned insertable and detachable structure, when the core support plate 110 is damaged, only the core support plate 110 can be replaced, thereby achieving significant effects in terms of maintenance and warranty and improving economic efficiency. In addition, in terms of the insertable and detachable structure, in order to provide a stronger fixing force, the lengths of both sides of the stepped portion are formed longer than the lengths of both sides of the core support plate 110, so that an interference fit method can be applied. In addition, a keyway can be formed on one side of the stepped portion, and a key can be formed on the side of the insertion portion of the core support plate 110, so that the key can be inserted into the keyway.

[0042] Furthermore, a groove is usually formed on the core support plate 110 so that the two ends of the stapler core 201 are connected and bent in opposite directions for terminal processing, thereby forming the above-mentioned groove.

[0043] An insertion space for inserting the iron core 201 is formed inside the iron core storage portion 200, which is hinged to the other side of the iron core support plate 110 formed with the lower plate 100, and is composed of a fixing rod, an iron core discharge port, an iron core pushing component and a first pushing elastic component.

[0044] In order to hook and fix one end of the first pushing elastic member, the fixing rod is vertically arranged inside the core receiving portion 200 and is located at the other side of the core receiving portion 200 where the core discharge port is formed.

[0045] The core discharge port 220 is located on the other side of the core storage portion 200 where the fixing rod is formed, and is a common structure for discharging the core 201 via the upper plate 300 described below.

[0046] The core pushing component is a structure for pushing the core 201 stored in the storage space for storing the core toward the core discharge port side. The first pushing elastic component has the characteristic of being connected to the core pushing component on one side and connected to the fixing rod on the other side, and can always push the core pushing component.

[0047] The above-mentioned core storage portion 200 is formed similarly to the structure of a conventional core storage portion. In order to fix the corners of the box, the core 201 is also formed similarly to the shape of the core support plate 110. In addition, in order to prevent the core from detaching, the lower part of the storage space for accommodating the core 201 is formed corresponding to the shape of the core 201, so as to fix the core 201.

[0048] Furthermore, the upper plate 300 is hingedly coupled to the portion where the core receiving portion 200 is hingedly coupled, and is located above the core receiving portion 200 . The upper plate 300 is composed of a second elastic pushing member, a support rod, and a hanging block.

[0049] The function of the upper plate 300 is to press the iron core 201 stored in the iron core storage part 200 and nail it to the various surfaces of the box for finally forming the corners of the box, and, on one side of the interior, a pulling elastic part is formed with the fixed part of the operating part described below as the center, and the other side is formed with a support rod connected to one side of the inclined part, and the other side of the interior of the upper plate 300 with the support rod is formed with a hanging block hung on the end of the pulling elastic part.

[0050] That is, the support rod is formed to support and fix the lower portion in order to prevent damage to the fixing member of the operation member described below, and the hook block is structured so as to hook the hook-pull elastic member.

[0051] The operating component is a core technical feature, and is composed of a handle 410 that can be directly pulled by the user, a fixing component, a movable pin, and a pulling elastic component.

[0052] One side of the upper part of the handle 410 is located inside the lower plate 100 and the upper plate 300, and the other side is located at the lower part of the lower plate 100. One side of the central part is hinged to the lower side of the lower plate 100 and rotates around the hinge. A hanging groove is formed on the upper side for selectively hanging on the movable pin 430. When the user selectively pulls it, the hanging groove wraps the movable pin 430. The movable pin 430 climbs the upper side of the fixed component and pushes to one side to naturally pull the upper plate 300 downward, thereby pressing the upper part of the iron core 201 to discharge it, thereby fixing the corners of the box.

[0053] As described above, the stapler for box corners, which is an unconventional stapler, has some difficulties in pressing the portion of the box corner that is located on the same line as the core support plate 110 of the upper plate 300 and the lower plate 100, just like a conventional stapler. Therefore, the handle 410 is formed so that there is no need to press the above-mentioned portion, and only the upper portion of the other side of the upper plate 300 where the handle and the core support plate 110 are formed needs to be pressed, thereby making the operation convenient.

[0054] Furthermore, although not shown, the handle 410 is formed in a continuously wave-shaped manner on the outer side of the lower portion, so that the user's fingers can be inserted to prevent slipping, and an anti-slip pad can be formed on the outer side as needed.

[0055] The fixing component is formed inside the upper plate 300, and the upper part is connected to the upper side of the interior of the upper plate 300. A connecting plate is formed on one side of the lower part to form a protrusion for inserting the second pushing elastic component, and an inclined portion is formed, which extends from the end of the connecting plate and is formed inclined downward, and a movable pin fixing plate is formed at the end in the same direction as the connecting plate, and the connecting plate is a component for connecting with the upper plate 300. The inclined portion has a channel function that allows the movable pin 430 to climb the inclined portion and move, and the other side of the movable pin 430 is supported by the support rod, and when the fixing component is pushed by pulling the handle 410, the fixing component can be prevented from being damaged.

[0056] In addition, in order to prevent the movable pin 430 from being separated from the original state after climbing the inclined surface, a fixing groove with a circular side is formed on the side of the movable pin fixing plate. Normally, the movable pin 430 is located in the fixing groove, and when the handle is in operation, it climbs the inclined portion and moves, and can be located in the fixing groove in its original state again by pulling the elastic component as described below.

[0057] The movable pin 430 is a structure located inside the upper plate 300 and in the fixing groove of the movable pin fixing plate. It is configured to move by selectively climbing the inclined portion through the handle 410, and pushing the fixing component to one side to move one side of the upper plate 300 downward.

[0058] The pulling elastic component is a structure like a conventional spring, which has a pulling characteristic. One side is connected to the inner side of the upper plate 300, and the other side is connected to the movable pin 430. After the movable pin 430 climbs the inclined part and moves through the handle 410, when the user releases the force applied to the handle 410, the movable pin 430 returns to its original state.

[0059] That is, when the operating member pulls and presses the handle 410 and one side of the upper plate 300 in opposite directions, the movable pin 430 is forcibly moved to eject the iron core 201 of the stapler.

[0060] Furthermore, a method for fixing the corners of a box using the above-mentioned stapler is described, which comprises a box shape forming step, a box introducing step, a corner forming step, and a corner fixing step.

[0061] The box shape forming step is a step of folding each side of the assembled box to form a corner. The box introduction step is a step of introducing each different side of the assembled box into the introduction space formed between the core support plate 110 of the lower plate 100 and the core storage portion 200, so that the inner side of each side of the box is completely in close contact with the core support plate 110.

[0062] The corner forming step is a step of bringing opposite ends of mutually different surfaces of the introduced box into contact with each other to form corners so that the ends are completely in close contact with each other.

[0063] The step of fixing the corners is to press the lower plate 100 and the upper plate 300 against each other from opposite directions or to pull and press the handle 410 and the upper plate 300 from opposite directions, and to nail the iron core 201 into each surface to fix each corner. Usually, if it is a multi-angle box, the above method is repeated at each corner to finally fix the corner part of the box.

[0064] The present invention is a stapler configured so that the user can double-pull the handle 410 to press the end 201 a of the core 201 in the above-mentioned stapler structure.

[0065] The present invention is a stapler for box corners that compresses the end of the iron core by double pulling of the handle, comprising: a lower plate 100, which is formed with an iron core support disk at the end of one side of the upper part, and the iron core support disk makes the iron core 201 of the stapler bend, and is gradually wider from the upper part to the lower part, and is formed with various inclined surfaces on the two side surfaces of the upper part, and extends from the end of the inclined surface to the lower part to form an insertion part; an iron core storage part 200, which is formed by the following structure: one end is hinged to one side of the lower plate 100, and multiple iron cores 201 are inserted horizontally in the interior, and an iron core discharge port for selectively discharging the inserted iron cores; an iron core pushing component that pushes the iron core 201; a fixing rod formed on the opposite side of the iron core pushing component; one side is connected to the iron The first pushing elastic component is connected to the core pushing component and the other side is connected to the fixing rod; the upper plate 300, one side of which is connected to the hinge and formed on the upper part of the core storage part 200, and a second pushing elastic component connected to one side of the core storage part 200 is formed inside; an introduction space is formed between the core support plate and the core storage part 200 for introducing introduction spaces in different directions of each surface of the assembled box; an operating component, one side of its upper part is located inside the lower plate 100 and the upper plate 300, and the other side is located at the lower part of the lower plate 100, and is composed of a handle 410, a fixing component, a movable pin 430, and a pulling elastic component. Thus, the user can operate the box corner stapler by pulling the handle.

[0066] The lower plate 100 is formed with: a pushing groove 1101 formed to form a predetermined angle, a sliding groove 1103 formed to be slidable forward and backward, a first rod 1100 formed with a fixing groove 1105 connected to a fixing pin, and a second rod 1200 connected to the fixing pin of the first rod 1100 and connected to the second rod 1200 through a fixing pin, and a third rod 1300 connected to the lower plate 100 is formed on the other side, and a rack 2100 that slides from the upper and lower parts through a sliding pin formed on the inner side of the core support plate 110 and connected to the sliding groove 1103 of the first rod 1100; a rotating gear 2200 that is meshed and rotated with the rack 2100 that slides from the upper and lower parts and is formed on both sides; and a pressing plate 2300 is formed on the outer side of the core support plate 110, connected to the rotating gear 2200 through a fixing pin, and formed on both sides.

[0067] The present invention described above will be described in more detail below.

[0068] The lower plate 100 , the core storage portion 200 , the upper plate 300 , the introduction space, and the operating member, which are basic components of the present invention, are omitted from the above description.

[0071] The pushing groove 1101 is formed through one side of the first rod 1100 at a predetermined angle, but an extension groove is formed at the lower portion thereof in a horizontal direction with a predetermined length so that the first rod 1100 can slide in a horizontal direction with a predetermined length.

[0072] The second rod 1200 is connected to the first rod 1100 via a fixing pin.

[0073] The second rod 1200 is provided with a second support member (not shown) for supporting the first and third rods 1100 and 1300 so as to prevent the first and third rods 1100 and 1300 connected to each other from deforming at a predetermined angle.

[0074] One side of the third rod 1300 is connected to the second rod 1200 via a fixing pin, and the other side is connected to the lower plate 100 .

[0075] A third supporting member (not shown) supported by the lower plate 100 is formed on the other side of the third rod 1300 to prevent the third rod 1300 from deforming at a predetermined angle.

[0076] A pulling member 1400 connected to the lower plate 100 is formed on one side of the first rod 1100 to return the first rod 1100 to its original position.

[0077] The pulling component 1400 is a structure that allows the first rod 1100 that slides toward the front of the stapler to return to its original position, and a connecting portion is formed on one side of the first rod 1100 to be connected to one side of the pulling component 1400, and a connecting portion is also formed on the lower plate 100 to be connected to the other side of the pulling component 1400.

[0078] The pulling member 1400 may be formed of a spring, or a component such as a cylinder may be applied to return the first rod 1100 to its original position.

[0079] The pressing portion includes a rack 2100 , a rotating gear 2200 , and a pressing plate 2300 .

[0080] The rack 2100 is formed inside the core support plate 110 and slides from the upper and lower parts via a sliding pin 2110 connected to the sliding groove 1103 of the first rod 1100 .

[0081] A through groove is formed at the center of the rack 2100 so that the first rod 1100 passes through. Sliding pin grooves are formed on both sides so that the sliding pin 2110 connected to the sliding groove 1103 of the first rod 1100 passes through.

[0082] Furthermore, a plurality of saw-tooth shapes are formed on both sides of the outer periphery of the rack 2100 .

[0083] The rotating gear 2200 is engaged and rotated with the rack 2100 sliding from the upper and lower parts, and is formed on both sides.

[0084] The rotating gear 2200 is formed with a sawtooth shape that meshes with the sawtooth shape of the rack 2100 , and is also formed with an extension shaft that extends long in the horizontal direction.
