Description

Technical Field

[0001] This patent belongs to the field of stationery technology, specifically relating to a push-to-release pen. Background Technology

[0002] Currently, the conventional design of push-button pens on the market places the push-button switch at the top of the pen barrel. By pressing the top push-button switch, the pen tip is extended and retracted. Although this design is simple, it cannot differentiate itself and attract consumers.

[0003] Currently, there are fun writing instruments that enhance their visual appeal and entertainment value by adding decorative designs to the pen cap, such as a writing instrument with a lucky cat design on the cap. However, existing fun writing instruments have the following technical problems: they typically add fixed decorative designs to writing instruments with caps, and these fixed designs lack interactivity and are not very effective in increasing fun and reducing stress. Therefore, we urgently need to design a fun writing instrument that interacts with the pressing action and has a better effect on increasing fun and reducing stress for click-type writing instruments. Summary of the Invention

[0004] The purpose of this patent is to provide a push-to-expand pen with a better user experience, in order to solve this technical problem:

[0005] This patent provides a push-to-open pen comprising an axially extending pen shell and a pen refill housed within the pen shell. The push-to-open pen also includes a pen refill assembly and a rotational vision component. The pen refill assembly includes a pen refilling component and a positioning component. The pen refill has a writing state and a non-writing state. In the writing state, the pen refill protrudes from the front end of the pen shell; in the non-writing state, the pen refill is located inside the pen shell. The front end of the positioning component abuts against the pen refill, and the rear end abuts against the pen refilling component. The pen refilling component has an initial position and a first position. When the pen refilling component moves from the initial position to the first position, the pen refilling component drives the positioning component to switch the pen refill between the writing state and the non-writing state. The rotational vision component is disposed on the outside of the pen shell and is connected to the pen refilling component. When the pen refilling component moves axially, the rotational vision component rotates around a rotation axis perpendicular to the pen shell.

[0006] Furthermore, the core ejector includes a rotation drive unit, and the rotation vision unit includes a rotation transmission unit. The rotation drive unit and the rotation transmission unit cooperate to cause the rotation vision unit to rotate about a rotation axis perpendicular to the direction of movement of the core ejector when the core ejector moves axially.

[0007] Furthermore, the rotation drive unit includes a first drive tooth, and the rotation transmission unit includes a second drive tooth. When the rotation vision component rotates, the first drive tooth and the second drive tooth mesh with each other.

[0008] Furthermore, when the core ejector is in the initial position, the first drive tooth and the second drive tooth do not mesh.

[0009] Furthermore, it also includes an actuating element, which has an outer surface suitable for finger touch and is drively connected to the core ejector.

[0010] Furthermore, the actuator also includes a rotating mounting hole, in which the rotating vision component is movably disposed.

[0011] Furthermore, the trigger also includes a first rotating connection portion, the pen housing includes a second rotating connection portion, and the range of motion of the rotating visual component is limited by the first rotating connection portion and the second rotating connection portion.

[0012] Furthermore, the second rotating connection includes a connecting groove, the actuating element includes a limiting block, and the rotating visual element includes a connecting segment.

[0013] Furthermore, the connecting segment is installed in the connecting groove, and the front end of the limiting block abuts against the connecting segment.

[0014] Furthermore, the trigger element is mounted on the core-exiting element.

[0015] Furthermore, the trigger pen also includes a rear end cap, and the trigger component includes a rear end cap mounting portion for mounting the rear end cap, and the range of motion of the trigger component is limited by the rear end cap.

[0016] Furthermore, the rotating vision component includes a vision section; when the rotating vision component rotates, the movement trajectory of the vision section is easily detected.

[0017] Compared to existing technologies, the beneficial effects of this patent are at least as follows:

[0018] 1. A rotating visual element is located on the outside of the pen casing and is connected to the lead ejector. When the lead ejector moves axially, the rotating visual element rotates around a rotation axis perpendicular to the pen casing. By incorporating this rotating visual element, this patent achieves a visual effect noticeable to the user when the lead ejector moves to move the pen lead, as the rotating visual element rotates around a rotation axis perpendicular to the pen casing. This rotating visual effect reflects the movement of the lead, establishes a causal relationship between the movement of the pen lead and the rotation of the visual element, and provides a unique visual effect and sense of satisfaction.

[0019] 2. Rotating visual components also provide more design possibilities for the press-to-produce pen, such as incorporating the rotating motion of daily life into the design, bringing visual effects and novel user experience, and stimulating consumers' desire to buy.

[0020] 3. The rotating vision component provided by this patent has reliable connection and high motion efficiency, resulting in a compact structure for the push-to-release pen. This patent makes minimal changes to the traditional press-button structure, making full use of the press-button components and resulting in lower design costs. Attached Figure Description

[0076] This patent provides a press-to-expand pen, including a pen housing 600 extending axially and a pen refill 700 housed in the pen housing 600. The press-to-expand pen also includes an extension assembly and a rotating visual component 500. The extension assembly includes an extension component 100 and a positioning component 200.

[0077] The pen refill 700 has a writing state and a non-writing state. In the writing state, the pen refill 700 protrudes from the front end of the pen casing 600; in the non-writing state, the pen refill 700 is located inside the pen casing 600. The front end of the positioning member abuts against the pen refill 700, and the rear end abuts against the refill ejector 100. The refill ejector 100 has an initial position and a first position. When the refill ejector 100 moves from the initial position to the first position, the refill ejector 100 drives the positioning member to switch the pen refill 700 between the writing state and the non-writing state. The refill ejector assembly of this patent can adopt a snap-action structure acceptable in the prior art to move the refill ejector 100 between the initial position and the first position and to put the pen refill 700 into the writing state or the non-writing state.

[0078] A specific click structure, in addition to the lead ejector 100, includes a positioning element 200, a return spring 900, and a housing guide rib 620 on the pen housing 600. The housing guide rib 620 engages in the gap between the guide blocks 140, preventing the lead ejector 100 from rotating during axial movement. The positioning guide tooth 150 at the front end of the lead ejector 100 periodically abuts against the positioning guide rib 210 on the positioning element 200 or the gap between the positioning guide ribs 210. The inclined surface at the rear end of the positioning guide rib 210 allows the positioning element 200 to rotate relative to the lead ejector 100 under the return force provided by the return spring 900. When the lead ejector 100 moves to the first position, the positioning element 200 moves until the positioning guide rib 210 disengages from the positioning guide tooth 150, allowing the positioning element 200 to switch between the second and third positions. The front end of the positioning element 200 abuts against the pen refill 700, forming a writing or non-writing state for the pen refill 700.

[0079] A rotating visual element 500 is disposed on the outside of the pen housing 600 and is connected to the lead-out component 100. When the lead-out component 100 moves axially, the rotating visual element rotates around a rotation axis perpendicular to the pen housing 600. By providing the rotating visual element 500, this patent allows the lead-out component 100 to move, causing the pen lead 700 to move. The rotating visual element 500 rotates around a rotation axis perpendicular to the pen housing 600, creating a visual effect noticeable to the user. This rotating visual effect reflects the movement of the lead-out component 100, establishing a causal relationship between the movement of the pen lead 700 and the rotation of the rotating visual element 500, and providing a unique visual effect and sense of satisfaction. The rotating visual element 500 also allows for more design flexibility in push-to-produce pens, such as incorporating everyday rotating motions into the design, resulting in visual effects and a novel user experience, stimulating consumers' desire to purchase.

[0080] Specifically, the core-extracting component 100 includes a rotation drive unit; the rotational vision component 500 includes a rotation transmission unit; the rotation drive unit and the rotation transmission unit cooperate to cause the rotational vision component to rotate about a rotation axis perpendicular to the direction of movement of the core-extracting component 100 when the core-extracting component 100 moves axially. More specifically, the rotation drive unit includes a first drive tooth 120; the rotation transmission unit includes a second drive tooth 520, and when the rotational vision component 500 rotates, the first drive tooth 120 and the second drive tooth 520 mesh with each other. When the core-extracting component 100 moves axially, the rotational vision component 500 is driven to rotate by the meshing first drive tooth 120 and second drive tooth 520.

[0081] Preferably, when the core ejector 100 is in the initial position, the first drive tooth 120 and the second drive tooth 520 are not engaged. When the core ejector 100 is in the initial position, the user can manually rotate the rotating visual component 500 to any angle, and then perform the core ejection and return actions to switch the core ejector 100 to the initial or first position. In this way, the rotation angle of the rotating visual component 500 when the core ejector 100 is in the first position changes with the initial angle position.

[0082] Specifically, this patent also includes an actuating element 300, which has an outer surface suitable for finger touch and is drively connected to the core-ejecting element 100. When the actuating element 300 is touched by a finger towards its front end, it drives the core-ejecting element 100.

[0083] The trigger 300 also includes a rotating mounting hole 340, within which the rotating visual component 500 is movably disposed. The rotating mounting hole 340 limits the rotation of the rotating visual component 500. Simultaneously, the trigger 300 can be designed with a synergistic visual effect with the shape of the rotating visual component 500, simulating familiar rotating movements to further utilize design space to create novel visual effects and provide psychological satisfaction. For example, the trigger 300 can be designed as a cat's body and head, and the rotating visual component 500 as a cat's tail; the movement of the rotating visual component 500 when rotating resembles the swaying of a cat's tail.

[0084] Specifically, the actuating element 300 further includes a first rotating connecting portion, the pen housing 600 includes a second rotating connecting portion, and the movement range of the rotating visual element 500 is limited by the first and second rotating connecting portions. The rotating visual element 500 includes a connecting segment; the connecting segment is installed in a connecting groove, and the front end of the limiting block abuts against the connecting segment to limit the movement range of the rotating visual element 500 in the pen axis. More specifically, the second rotating connecting portion includes a first connecting groove 611b and a second connecting groove 611a, the actuating element 300 includes a first limiting block 310 and a second limiting block 320, the first connecting segment 540 of the rotating visual element 500 is engaged between the first connecting groove 611b and the first limiting block 310, and the second connecting segment 530 is engaged between the second connecting groove 611a and the second limiting block 320, respectively constituting the limiting of the two connecting segments of the rotating visual element 500. Preferably, to ensure the stability of the connection, the first rotating connecting part and the second rotating connecting part have corresponding dimensions. The first rotating connecting part can slide within the second rotating connecting part, and the second rotating connecting part guides the first connecting part. More preferably, for ease of installation and processing, the dimensions of the first rotating connecting part and the second rotating connecting part are adapted to the rotational vision component 500 to ensure accurate axial movement of the rotational vision component 500 and to prevent wobbling. For example, both the first connecting segment 540 and the second connecting segment 530 are cylinders. The diameter of the first connecting segment 540 is smaller than that of the second connecting segment 530. The dimensions of the first connecting groove 611b and the first limiting block 310 are smaller than those of the second connecting groove 611a and the second limiting block 320, respectively, to allow the first connecting segment 540 to slide with high precision.

[0085] To achieve a compact and efficient connection structure, the actuating element 300 is fitted onto the lead-extracting element 100. To limit the axial movement of the actuating element 300, the lead-extracting pen also includes a rear end cap 400. The lead-extracting element 100 includes a rear end cap mounting portion 100 for mounting the rear end cap 400. The movement range of the actuating element 300 is limited by the rear end cap 400, and it is abutted by the rear end cap 400 when it moves to its extreme rearward position. The actuating element 300 also includes an actuation limiting rib 331. The pen housing 600 includes a housing connecting portion 610 for forming a second rotating connection portion. When the actuating element 300 moves to its extreme position at its front end, the housing connecting portion 610 abuts against the actuation limiting rib 331.

[0086] The actuator 300 also includes a second material-stealing hole 351 for material removal during injection molding to prevent shrinkage and other injection molding problems. The second material-stealing hole 351 can be sealed by a plug 350 to avoid affecting the appearance. Similarly, the core ejector 100 may also include a first material-stealing hole 160.

[0087] Preferably, the rotating visual member 500 includes a visual section 510; when the rotating visual member 500 rotates, the movement trajectory of the visual section 510 is easily noticeable. For example, the visual section 510 may have a certain angle with the rotation axis, such as 60°~120°, for example 90°.

[0088] The push-to-eject pen may also include other push-to-eject pen structures in the prior art, such as a pen neck 800, which can be threaded to the pen housing 600 via an internal thread 630. The pen neck 800 is used to fix the return spring 900 and to facilitate gripping.
