Description

Flat stapler Technical Field

[0001] This application relates to the field of stationery, and more specifically, to a flat stapler. Background Technology

[0002] Flat staplers are commonly used for binding paper as a stationery item. Traditional flat staplers are curved staplers. After the staple penetrates the paper, the staple foot has an arc-shaped structure, which shortens the effective penetration thickness of the staple and thus affects the binding thickness. In addition, the arc-shaped staple foot occupies more space in the thickness direction of the paper. When multiple bound documents are stacked, the thickness of the documents on the stapled side will be significantly greater than the thickness of the documents on the other side.

[0003] To overcome the aforementioned shortcomings, a flat stapler has been designed in related technologies. The flat stapler includes a base, a pressure plate, a staple-driving structure, a flat staple structure, and a swinging component. The pressure plate, staple-driving structure, and flat staple structure are all connected to the base. The pressure plate transmits the pressure applied by the user to the staple-driving structure, which pushes the staples out of the staple slots. The flat staple structure carries the paper and the dispensing staples and provides the flat staple action. When the user binds documents, as the user presses the flat stapler, the flat staple structure sequentially passes through an initial state, a paper-threading state, and a flat staple state, thus achieving the flat staple effect. The swinging component connects to the staple-driving structure, driving the flat staple structure during the user's pressing of the flat stapler, enabling the flat staple structure to switch states and complete the flat staple action.

[0004] However, the current flat stapler has poor driving stability between the swinging component and the flat staple structure, which can easily cause jamming during the switching of the flat staple structure's shape, making it difficult to bind documents smoothly. Summary of the Invention

[0005] A primary objective of this application is to overcome at least one of the deficiencies of the prior art and provide a flat stapler. This flat stapler improves the smoothness of document binding by changing the structure of the oscillating component, thereby achieving stable driving of the oscillating component on the flat staple structure.

[0056] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0057] The features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0058] Currently, in related technologies, the swing component of a flat stapler has a connecting end and a swing end. The swing component is hinged to the staple structure or pressure plate through the connecting end. When the user presses the stapler, the pressure plate and staple structure are pressed downward, causing the connecting end of the swing component to move downward. At the same time, the swing segment of the swing component swings backward, thereby driving the flat staple structure to switch states.

[0059] The inventors discovered through research that since the swinging component is fixed only by hinge at the connecting end, the connection at the connecting end may loosen after long-term use of the stapler. This results in insufficient swing angle of the swinging end after the user presses the stapler, making it difficult to drive the flat staple structure into place. This causes the state switching of the flat staple structure to become stuck, affecting the flat staple effect of the stapler and even making it difficult to press the stapler.

[0060] This application designs a flat stapler and improves the structure of the oscillating component, making the oscillating component's drive on the flat staple structure more stable.

[0061] The embodiments of the flat stapler of this application are described below with reference to the accompanying drawings. For ease of explanation, the width direction of the flat stapler 10 is defined as the first direction D1, the length direction of the flat stapler 10 is defined as the second direction D2, and the height direction of the flat stapler 10 is defined as the third direction D3, wherein the first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0062] As shown in Figures 1 to 5, the embodiments of the flat stapler 10 of this application include: a housing, a base 210, a stapler structure 300, a pressure plate 410, a flat stapler structure 500, and a swinging component 600.

[0063] Specifically, referring to Figures 1 and 2, the housing includes a first housing 110 and a second housing 120. The first housing 110 is connected to the base 210 to enclose the base 210 and the flat staple structure 500, making the flat stapler more aesthetically pleasing. Simultaneously, the first housing 110 also increases the weight of the bottom of the flat stapler 10, making it more stable. Referring to Figure 3, the second housing 120 is connected to the pressure plate 410 to enclose the pressure plate 410, increasing aesthetics while providing a better grip for the flat stapler 10, making it easier for the user to apply pressure when stapled.

[0064] As shown in Figures 3 and 4, the pressure plate 410 and the nailing structure 300 are both hinged to the base 210, wherein the nailing structure 300 is located between the pressure plate 410 and the base 210.

[0065] The pressure plate 410 and the nailing structure 300 can be coaxially hinged to the base 210, or they can be hinged to the base using different hinge axes. For example, as shown in Figure 4, the nailing structure 300 is hinged to the base 210 via a first hinge axis 220. The pressure plate 410 can be hinged to the base 210 via a second hinge axis 420.

[0066] It should be noted that the second hinge shaft 420 is closer to the nail outlet end of the nailing structure 300 than the first hinge shaft 220. This arrangement makes the flat stapler 10 easier to use when nailing.

[0067] Referring again to Figures 3 and 4, the pressure plate 410 is used to drive the staple pressing structure 320 to press the staples. Specifically, the staple pressing structure 300 includes a staple track structure 310 and a staple pressing structure 320 hinged to the staple track structure 310. The staple track structure 310 has a staple groove 315 for receiving staples and a staple outlet 3125 communicating with the staple groove 315. The staple pressing structure 320 includes a staple pressing plate 321 for pressing the staples out of the staple outlet 3125.

[0068] As shown in Figures 3 and 5, the flat nail structure 500 is disposed on the base 210. The flat nail structure 500 has an initial form, a paper-threading form, and a flat nail form. The swing member 600 has a connecting end 601 and a swing end 602. The connecting end 601 is hinged to the pressing nail structure 320, and the swing end 602 is used to drive the flat nail structure 500 to switch from the paper-threading form to the flat nail form.

[0069] It should be emphasized that the swing member 600 also includes an abutment portion 640, which can abut against the nail track structure 310. The abutment portion 640 is located between the connecting end 601 and the swing end 602 of the swing member 600. The abutment portion 640 and the nail track structure 310 abut against each other, which adds a new abutment point at the center of the swing member 600, making the swing member 600 form a lever-like structure. That is to say, the position of the abutment portion 640 and the nail track structure 310 abut against each other is equivalent to the support point of the lever structure. When the connecting end 601 of the swing member 600 is driven, the other end of the swing member 600, namely the swing end 602, can swing, thereby achieving stable driving of the flat nail structure 500.

[0070] Further, as shown in Figures 3 and 4, the pressure nail structure 320 may include a pressure nail plate 321, a third side plate 322, a fourth side plate 323 (shown in Figure 4), and a top plate 324. The top plate 324 is opposite to the pressure plate 410. The third side plate 322 and the fourth side plate 323 are spaced apart along the first direction D1 and are angled to the top plate 324. The pressure nail plate 321 is located at the end of the top plate 324 away from the first hinge axis 220. The bottom edge of the pressure nail plate 321 protrudes beyond the bottom edges of the third side plate 322 and the fourth side plate 323. The third side plate 322 and the fourth side plate 323 are located outside the nail track structure 310 in the first direction D1. When the user nails, the pressure plate 410 moves the nail pressing structure 320 downward, the nail pressing plate 321 enters the nail groove 315 and knocks the staple out from the nail outlet 3125, the third side plate 322 and the fourth side plate 323 fall to both sides of the nail path structure 310 to avoid interference between the third side plate 322 and the fourth side plate 323 and the nail path structure 310.

[0071] The specific structure of the oscillating component 600 is described below with reference to the attached diagram.

[0072] Referring to Figures 3 and 5 in conjunction with Figure 6, in some embodiments, the swing member 600 includes a first swing arm 610, a second swing arm 620, and a connecting plate 630.

[0073] The first swing arm 610 and the second swing arm 620 are spaced apart along the first direction D1. The connecting plate 630 connects the first swing arm 610 and the second swing arm 620. The connecting plate 630 can fix the first swing arm 610 and the second swing arm 620, reducing the probability of the first swing arm 610 and the second swing arm 620 separating in the first direction D1.

[0074] Further, as shown in Figure 4, the nail track structure 310 is located between the first swing arm 610 and the second swing arm 620. The first end of the first swing arm 610 and the first end of the second swing arm 620 are both hinged to the pressure nail structure 320. The second end of the first swing arm 610 and the second end of the second swing arm 620 are both driven to engage with the flat nail structure 500.

[0075] Specifically, referring to Figure 4, the first end of the first swing arm 610 and the first end of the second swing arm 620 are hinged to the third side plate 322 and the fourth side plate 323 of the pressure pin structure 320 (shown in Figure 3). The first end of the first swing arm 610 and the first end of the second swing arm 620 form the connecting end 601 of the swing member 600.

[0076] As shown in Figures 3, 5, and 6, in some embodiments, the first end of the first swing arm 610 and the first end of the second swing arm 620 can be hinged to the third side plate 322 and the fourth side plate 323 via a third hinge shaft 650. Exemplarily, the third hinge shaft 650 can pass sequentially through the first swing arm 610, the third side plate 322, the fourth side plate 323, and the second swing arm 620 in the first direction D1, thereby ensuring the hinge stability between the connecting end 601 of the swing member 600 and the pressure pin structure 320.

[0077] Furthermore, as shown in Figures 3 and 5, the abutting portion 640 is disposed on the connecting plate 630 and abuts against the surface of the nail channel structure 310 facing the pressing nail structure 320.

[0078] Specifically, in some embodiments, the surface of the nail track structure 310 facing the pressure nail structure 320 is provided with a protrusion 3111, and the abutment portion 640 abuts against the protrusion 3111. The protrusion 3111 can achieve a tight fit with the abutment portion 640, thereby improving the abutment stability between the abutment portion 640 and the nail track structure 310, thereby achieving stable support for the swing member 600.

[0079] For example, as shown in FIG3, the abutment portion 640 is an arc-shaped plate located at the end of the connecting plate 630 away from the nail outlet 3125. When the user nails, the abutment portion 640 will slide as the user applies pressure. Setting the abutment portion 640 as an arc-shaped plate can improve the smoothness of the sliding of the abutment portion 640 and reduce the probability of jamming when the user nails.

[0080] For example, the abutment portion 640 can be integrally formed with the connecting plate 630. The abutment portion 640 can be formed from the connecting plate 630 by bending or stamping.

[0081] The specific structure of the spike track structure 310 is described below with reference to the attached diagram.

[0082] Referring to Figures 7 and 8 in conjunction with Figures 2 and 3, in some embodiments, the nail channel structure 310 includes a cover 311, a first box 312, and a nail pusher assembly 314.

[0083] Specifically, the cover 311 is hinged to the base 210 and has a receiving space. Furthermore, the cover 311 is hinged to the base via a first hinge shaft 220, and the cover 311 can provide stable support for the nail track structure 310.

[0084] It should also be noted that the protrusion 3111 can be provided on the cover 311. Specifically, the cover 311 has two side walls arranged opposite to each other along the first direction, and each side wall is provided with a protrusion 3111. The abutting part 640 abuts and cooperates with both protrusions 3111 at the same time.

[0085] As shown in Figures 7 and 8, the first housing 312 is disposed within the receiving space, and a staple slot 315 is provided inside the first housing 312. The staple outlet 3125 is disposed in the first housing 312 and communicates with the staple slot 315, and the staple outlet 3125 extends out of the cover 311. When staples are inserted, the user squeezes the flat stapler 10. At this time, the staple pressure plate 321 can enter the staple slot 315, and the staple opposite to the staple outlet 3125 is ejected from the staple outlet 3125. Pressure is continuously applied to the ejected staples, causing the staples to penetrate the paper. When the staple penetrates the paper and abuts against the flat staple slot 531, as the user's pressure continues, the staple foot bends under the stop of the flat staple slot, thereby achieving staple holding.

[0086] A staple pusher assembly 314 is disposed in the first housing 312, and at least a portion of the staple pusher assembly 314 extends into the staple slot to push the staple. The staple pusher assembly 314 is used to apply pressure to the staple, pushing the staple toward the staple outlet 3125 so that the staple presser plate 321 can eject the staple when it is stapled again.

[0087] For example, the staple pusher assembly 314 may include a pusher head, a pusher rod, and a return spring. A stop may be provided at one end of the pusher rod near the first hinge shaft 220. The pusher head is sleeved on the pusher rod and can slide along it. One end of the return spring abuts against the pusher head, and the other end abuts against the stop, thus pushing the pusher head towards the staple outlet 3125. The pusher head can push the staple towards the staple outlet.

[0088] Specifically, as shown in Figure 7, in some embodiments, the first housing 312 includes a first side plate 3121, a second side plate 3122, a bottom plate 3123, and a baffle 3124. The first side plate 3121 and the second side plate 3122 are disposed opposite each other along a first direction D1, and the bottom plate 3123 connects the first side plate 3121 and the second side plate 3122. The first side plate 3121 has a first end near the hinge axis of the staple track structure 310 and a second end away from the hinge axis of the staple track structure 310. The baffle 3124 is disposed at the second end of the first side plate 3121 and connected to the second side plate 3122. The baffle 3124 and the staple pusher assembly 314 are used to clamp staples. Specifically, staples can be clamped between the baffle 3124 and the pusher head of the staple pusher assembly 314, and the staple outlet 3125 is disposed on the bottom plate 3123 and adjacent to the baffle 3124.

[0089] When the flat stapler 10 is using a stapler, sometimes the staple gets stuck in the exit slot 3125 after the staple pressure plate 321 presses the staple out. The inventors discovered through research that the reason the staple gets stuck is that the first side plate 3121 and the second side plate 3122 exert a limiting force on the staple feet, making it difficult for the staple to fall out of the exit slot 3125.

[0090] Based on this, as shown in Figure 8, in some embodiments, a first notch 3126 can be provided on the first side plate 3121 and the second side plate 3122. The first notch 3126 is located on the edge of the first side plate 3121 near the staple outlet 3125 and adjacent to the baffle 3124. The provision of the first notch 3126 causes the first side plate 3121 and the second side plate 3122 to lose the limiting force on the staple feet, making it easier for the staple to fall from the staple outlet 3125.

[0091] In other embodiments, the first notch 3126 may be provided only on the first side plate 3121 and the second side plate 3122.

[0092] Furthermore, as shown in FIG8, in some embodiments, the size of the first notch 3126 is greater than or equal to the size of a staple in the extending direction of the staple path structure 310. That is to say, the first notch 3126 avoids at least the size of a staple, so that the staple pressed out by the staple presser plate 321 can fall smoothly from the staple outlet 3125.

[0093] Furthermore, as shown in Figures 7 and 8, in some embodiments, the staple path structure 310 further includes a second box 313 disposed within the first box 312, with a staple groove 315 formed between the second box 313 and the first box 312 to accommodate staples. Specifically, the second box 313 includes a fifth side plate and a sixth side plate spaced apart along a first direction D1. The fifth side plate is parallel to the first side plate 3121, and the sixth side plate is parallel to the second side plate 3122. The fifth side plate and the first side plate 3121 can be used to accommodate one staple leg, and the space between the sixth side plate and the second side plate 3122 is used to accommodate the other staple leg.

[0094] To further reduce the probability of staples getting stuck at the staple exit point 3125 during staple making, a second notch 3131 can be provided on the second box 313, and the second notch 3131 is provided in correspondence with the first notch 3126.

[0095] In some embodiments, the size of the second notch 3131 may be the same as that of the first notch 3126.

[0096] It should also be noted that a first reset member 330 is provided between the first housing 110 and the staple track structure 310. The first reset member 330 is used to apply a reset force to the staple track structure 310 so that after the user finishes stapleping, the stapler can return to the open state so that stapleping can be performed again next time.

[0097] As shown in Figures 5 and 9, in some embodiments, the flat stapler 10 can achieve staple loading through a pop-up staple path.

[0098] Specifically, the first box 312 can be configured to slide relative to the cover 311. The first box 312 can have an upper nail position and a retracted position. When the first box 312 is in the upper nail position, the nail groove 315 is exposed outside the cover 311; when the first box 312 is in the retracted position, the nail groove is inside the cover 311.

[0099] Furthermore, the flat stapler 10 can extend and retract the first cartridge 312 via the pop-out adjustment device 700.

[0100] Specifically, the pop-out adjustment device 700 is located at the hinge end of the nail track structure 310. The pop-out adjustment device 700 has a pop-out mode and a limiting mode. When the pop-out adjustment device 700 switches from the limiting mode to the pop-out mode, the first box 312 moves from the retracted position to the nail-up position.

[0101] The pop-out adjustment device 700 includes an adjustment button 710, a limiting member 720, a latch 721, and a fifth reset member 730. The adjustment button 710 is located at the first hinge shaft 220 and is drivenly connected to the limiting member 720. The fifth reset member 730 is located between the cover 311 and the first housing 312. The cover 311 is hinged to the first hinge shaft 220 and can apply a continuous pushing force to the first end of the fifth reset member 730. The second end of the fifth reset member 730 abuts against the first housing 312, pushing the first housing 312 in a direction extending out of the cover 311 (second direction D2). The limiting member 720 is provided with a hook 721, and the first box 312 is provided with a latch 3127. When the adjustment button 710 is in the normal position, the hook 721 of the limiting member 720 can engage with the latch 3127 of the first box 312, and the first box 312 can be stably in the retracted position. At this time, the fifth reset member 730 is compressed. When the adjustment button 710 is pressed, the limiting member 720 is lifted, and the hook 721 on the limiting member 720 loses its limiting effect on the first box 312. The first box 312 can move upward to the staple position under the action of the reset force of the fifth reset member 730, so that the staple groove 315 is exposed in the cover 311, and the user can insert staples into the staple groove 315. After staples are inserted, the user pushes the first box 312 to the retracted position, and the hook 721 can re-engage in the latch, thus limiting the first box 312.

[0102] It should be noted that the adjustment button 710, limit member 720, hook 721, and fifth reset member 730 of the pop-out adjustment device 700 are all existing technologies, and their structures will not be described in detail.

[0103] The specific structure of the flat nail structure 500 is described below with reference to the attached diagram.

[0104] As shown in Figures 3 and 5, in some embodiments, the flat nail structure 500 includes a support plate 510, a flat nail plate 520, and a flat nail block 530.

[0105] A support plate 510 is disposed on the base 210, and a flat staple plate 520 is disposed on the support plate 510. The flat staple plate 520 has a clearance opening 521, and a flat staple block 530 has a flat staple groove 531, through which the flat staple block 530 passes. Specifically, the flat staple plate 520 is used to support paper, and the flat staple block 530 is used to receive staples. The flat staple groove 531 on the flat staple block 530 can apply a resisting force to the staple feet, thereby bending the staple feet. The support plate 510 is used to adjust the height of the flat staple plate 520.

[0106] Specifically, the support plate 510 is slidably disposed on the base 210 along the second direction D2. The support plate 510 has a supporting position and a clearance position. When the support plate 510 is in the supporting position, it supports the flat nail plate 520, and the flat nail plate 520 cannot be pressed. When the support plate 510 is in the clearance position, it loses its support for the flat nail plate 520, allowing the end of the flat nail plate 520 with the clearance opening 521 to be compressed along the third direction D3. The flat nail block 530 is telescopically disposed within the clearance opening 521 along the third direction D3. Since the flat nail plate 520 has two states—compressible and incompressible—while the flat nail block 530 can always be compressed, the effect of flat nailing can be achieved through the mutual cooperation of their heights.

[0107] When the flat nail structure 500 is in its initial state, the support plate 510 is in the support position; when the flat nail structure 500 is in the paper-threading state, the support plate 510 is in the support position and the flat nail block 530 is lower than the flat nail plate 520; when the flat nail structure 500 is in the flat nail state, the support plate 510 is in the clearance position and the flat nail plate 520 can be compressed.

[0108] The following describes the state switching process of the nailing structure in conjunction with the user's nailing action. When the flat nail structure 500 is in its initial state, the support plate 510 is in the supporting position. At this time, the support plate 510 can support the flat nail plate 520, and the flat nail plate 520 cannot be compressed. Before nailing, the user places the paper between the flat nail plate 520 and the nail path structure 310.

[0109] When staples are inserted, the user presses the second housing 120. The pressure is transmitted to the staple pressing structure 320 via the pressure plate 410. The staple pressing plate 321 of the staple pressing structure 320 squeezes the staple, forcing it out from the staple outlet 3125. At this time, the staple feet can gradually penetrate the paper. After the staple feet penetrate the paper, the flat staple block 530 is further compressed, allowing as many staple feet as possible to penetrate the paper. When the flat staple structure 500 is in the paper-penetrating state, the support plate 510 is in the supporting position, thus supporting the main flat staple plate 520 and preventing it from falling. The flat staple block 530 is squeezed by the staple feet and is lower than the flat staple plate 520, ensuring that the staple can penetrate the paper.

[0110] As the user continues to squeeze the flat stapler 10, the flat staple structure 500 switches to flat staple mode. At this time, the swinging component 600 drives the support plate 510 to move to the clearance position. When the support plate 510 moves to the clearance position, the flat staple plate 520 can be compressed, and the paper cover is pressed downwards along with the flat staple plate 520. When the flat staple plate 520 is compressed to approximately the same height as the bottom of the flat staple groove 531, the staple feet can be bent. Due to the shape of the flat staple groove 531 and the approximately equal height of the flat staple plate 520 and the bottom of the flat staple groove 531, the staple feet form a straight structure, realizing the flat staple.

[0111] After nailing is completed, the support plate 510 is reset by the action of the second reset member 540, the flat nail plate 520 is reset by the action of the third reset member 550, and the flat nail block 530 is reset by the action of the fourth reset member 560.

[0112] It should be noted that the support plate 510, flat nail plate 520, flat nail block 530, as well as the second reset member 540, the third reset member 550 and the fourth reset member 560 of the above-mentioned flat nail structure 500 are all prior art, and their specific structures will not be described in detail.
