Abstract
Description
- This application claims the priority benefit of Taiwan application serial no. 107122610, filed on Jun. 29, 2018. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
- The disclosure relates to a retractable pen, and particularly relates to a retractable pen adapted for being accommodated in a portable electronic device.
- Currently, many portable electronic devices (such as tablet computers, smart phones, and laptop computers) all adopt touch display screens so that users may control the electronic products by directly inputting command on the display screens. In the existent touch display screen, the touch function is mostly performed by the user's finger or a stylus.
- However, in order to facilitate the user's operation, the portable electronic device is mostly provided with a groove to accommodate the stylus. But in the existent groove design, for the convenience of the user to take out and put back the stylus, the housing of the portable electronic device is mostly formed with a broken surface or a recessed portion so that the user may easily apply a force to the stylus in order to take out the stylus from inside the portable electronic device. Nevertheless, the broken surface or the recessed portion results in an unappealing appearance of the portable electronic device.
- The disclosure provides a retractable pen that is switchable between extending and retracting states, so that the retractable pen may be accommodated in or taken out from a portable electronic device easily.
- The retractable pen of the disclosure is adapted for being accommodated in the portable electronic device. The retractable pen includes a housing, a shaft, a cap, a driving member and an elastic member. The shaft is fixed in the housing and has a first ratcheting structure. The cap has a second ratcheting structure movably engaged with the first ratcheting structure. The driving member rotatably sheathes the shaft and is located in the cap. The driving member has a third ratcheting structure. The elastic member sheathes the shaft and leans against between the shaft and the driving member. The elastic member constantly drives the driving member toward the first ratcheting structure or the second ratcheting structure. In a first state, the third ratcheting structure leans against the first ratcheting structure. In a second state, the third ratcheting structure is movably engaged with the second ratcheting structure and leans against the first ratcheting structure so as to push the cap away from the housing.
- Based on the foregoing, regarding the retractable pen, owing to the cooperation between the driving member and the elastic member, and depending on whether the first ratcheting structure of the shaft, the second ratcheting structure of the cap and the third ratcheting structure of the driving member lean against one another or not, the cap of the retractable pen may be moved away from the housing so that the retractable pen is switched to the extending state, or the cap may be moved closer to the housing so that the retractable pen is switched to the retracting state. In this way, through the extending and retracting states of the retractable pen, the retractable pen may either be accommodated in the portable electronic device or be easily taken out from the portable electronic device.
- To make the aforementioned and other features and advantages of the disclosure more comprehensible, several embodiments accompanied with drawings are described in detail as follows.
- The accompanying drawings are included to provide a further understanding of the disclosure, and are incorporated in and constitute a part of this specification. The drawings illustrate exemplary embodiments of the disclosure and, together with the description, serve to explain the principles of the disclosure.

FIG. 1A andFIG. 1B are schematic views of a retractable pen and a portable electronic device according to an embodiment of the disclosure for illustrating extending and retracting states of the retractable pen and the corresponding relationship between the retractable pen and the portable electronic device.FIG. 1C andFIG. 1D are schematic views showing the extending and retracting states of the retractable pen. In this embodiment, aretractable pen 100 is a stylus, for example, and is adapted for being accommodated in a portable electronic device 20 (such as a tablet computer, but is not limited thereto), so that the user may conveniently take out theretractable pen 100 from the portableelectronic device 20 and use theretractable pen 100 to operate and control the portableelectronic device 20. Once theretractable pen 100 is no longer in use, it may then be accommodated in the portableelectronic device 20 to be carried around easily. Herein theretractable pen 100 includes ahousing 110, ashaft 120 and acap 130. As shown inFIG. 1A , theretractable pen 100, when accommodated in the portableelectronic device 20, is substantially completely hidden in the body of the portableelectronic device 20, so that structurally there is no exposed portion to which the user may apply a force for taking out theretractable pen 100. Therefore, to facilitate the user's taking out and putting back theretractable pen 100, theretractable pen 100 in this embodiment is structurally provided with thecap 130 that may be pressed by a force and be moved as in the state ofFIG. 1C , so that theretractable pen 100 may be switched from a first state (retracting state) inFIG. 1C to a second state (extending state) ofFIG. 1D . That is, thecap 130 is pushed away from thehousing 110 to achieve the desired extending state. If the foregoing process is explicated with reference toFIG. 1A andFIG. 1B , it can be clearly known that thecap 130 of theretractable pen 100 accommodated in the portableelectronic device 20 is pressed by the user (that is, provided with a force F1), so that theretractable pen 100 may be switched to the extending state as shown inFIG. 1B , and the user may then conveniently take out theretractable pen 100. After the retractable pen is used and needs to be put back into the portableelectronic device 20, the user only needs to press thecap 130 again to switch theretractable pen 100 to the first state, and theretractable pen 100 may then be completely hidden in the portableelectronic device 20 again as shown inFIG. 1A . -
FIG. 2A is an exploded view of some components of the retractable pen.FIG. 2B shows the cap from another perspective.FIG. 2C shows a first ratcheting structure from another perspective.FIG. 3A toFIG. 3C are schematic views showing some components of the retractable pen in the first state. HereinFIG. 3A andFIG. 3B are provided as cross-sectional views to facilitate identifying the state of the internal components. With reference toFIG. 2A toFIG. 2C andFIG. 3A toFIG. 3C , in this embodiment, theretractable pen 100 further includes a drivingmember 140 and anelastic member 150, and theshaft 120 is fixed in thehousing 110 and has afirst ratcheting structure 121. Thecap 130 has asecond ratcheting structure 131 movably engaged with thefirst ratcheting structure 121. The drivingmember 140 rotatably sheathes theshaft 120 and is located in thecap 130, and has athird ratcheting structure 141. Theelastic member 150 sheathes theshaft 120 and leans against between theshaft 120 and the drivingmember 140. Theelastic member 150 constantly drives the drivingmember 140 closer to thefirst ratcheting structure 121 or thesecond ratcheting structure 131. In the first state, the drivingmember 140 is driven by theelastic member 150, so that thethird ratcheting structure 141 leans against and is blocked by thefirst ratcheting structure 121. In the second state, the drivingmember 140 is driven by theelastic member 150, so that thethird ratcheting structure 141 is movably engaged with thesecond ratcheting structure 131 and leans against and is blocked by thefirst ratcheting structure 121 so as to push thecap 130 away from thehousing 110. - To be more specific, the
shaft 120 further includes ashaft member 122 and a fixingmember 123. Theshaft member 122 has a first end E1 and a second end E2 opposite to the first end E1. Thefirst ratcheting structure 121 is disposed at the first end E1. The drivingmember 140 rotatably sheathes theshaft member 122 to be positioned between the first end E1 and the second end E2. The second end E2 of theshaft member 122 is inserted through the fixingmember 123 and is fixed in thehousing 110 by the fixingmember 123. Theelastic member 150 sheathes theshaft member 122 and leans against between the fixingmember 123 and the drivingmember 140. As shown inFIG. 3A andFIG. 3B , the inner wall of the fixingmember 123 is formed with astep portion 123 a, so that one end of theelastic member 150 is received in the fixingmember 123 and leans against thestep portion 123 a, and the other end of theelastic member 150 leans against the drivingmember 140. Here, thefirst ratcheting structure 121, theshaft member 122 and the fixingmember 123 of theshaft 120 may be viewed as an integral structure fixed in thehousing 110. That is, there is no relative movement between thefirst ratcheting structure 121, theshaft member 122 and the fixingmember 123 and thehousing 110. - Moreover, the
retractable pen 100 further includes a blockingmember 160 fixed on the inner wall of thecap 130 to block and maintain the drivingmember 140 in thecap 130 so as to prevent the drivingmember 140 from sliding out of thecap 130 when it is actuated. - Besides, with reference to
FIG. 2A andFIG. 2C , thefirst ratcheting structure 121 in this embodiment has a plurality of first tooth portions G1 and a plurality of auxiliary tooth portions G1 a, and the first tooth portions G1 and the auxiliary tooth portions G1 a are alternately arranged around an axis X1 of ashaft 122. The auxiliary tooth portion G1 a is connected between two adjacent first tooth portions G1 to form an auxiliary groove portion L1 a. A first groove portion L1 is formed between two adjacent first tooth portions G1 to which the auxiliary tooth portion G1 a is not connected. Therefore, the first groove portion L1 and the auxiliary groove portion L1 a are also alternately arranged around the axis X1 at intervals. Here, with the axis X1 used as a reference standard, a radial thickness T1 of the first tooth portion G1 with respect to the axis X1 is greater than a radial thickness T2 of the auxiliary tooth portion G1 a with respect to the axis X1, so that the auxiliary groove portion L1 a may be formed between the two adjacent first tooth portions G1 connected to the auxiliary tooth portion G1 a. In other words, for thefirst ratcheting structure 121, the first groove portion L1 may be viewed as a through opening, but the auxiliary groove portion L1 a may not. - With reference to
FIG. 2A andFIG. 2B , thesecond ratcheting structure 131 in this embodiment has a plurality of second tooth portions G2 and a plurality of second groove portions L2, and the second tooth portions G2 and the second groove portions L2 are arranged around the axis X1. The second tooth portion G2 movably leans against the first groove portion L1 or the auxiliary groove portion L1 a along the axis X1. The first tooth portion G1 movably leans against the second groove portion L2 along the axis X1. Accordingly, thecap 130 and theshaft 120 may slide relative to each other along the axis X1. At the same time, thethird ratcheting structure 141 in this embodiment is constituted by three third tooth portions G3 (but not limited thereto). Depending on whether thecap 130 is pressed with a force or not, the third tooth portion G3 switchably leans against the first tooth portion G1 and the second tooth portion G2 due to the rotation of the drivingmember 140 along the axis X1, so that the drivingmember 140 may drive thecap 130 away from thehousing 110 or toward thehousing 110. -
FIG. 4 toFIG. 6 are schematic partial views respectively showing the retractable pen in different states.FIG. 7A toFIG. 7C are schematic views showing the retractable pen in the extending state. HereinFIG. 7B andFIG. 7C are illustrated as partial cross-sectional views to facilitate identifying the relationship among the internal components. First, please refer toFIG. 3A toFIG. 3C andFIG. 4 . As shown inFIG. 3A toFIG. 3C (also as shown inFIG. 1A andFIG. 1C ), at this time, theretractable pen 100 is adapted for being accommodated in the portableelectronic device 20, i.e., in the first state. The drivingmember 140 is driven by theelastic member 150, so that the third tooth portion G3 leans against and is blocked by the auxiliary tooth portion G1 a and the second tooth portion G2. - Therefore, in order to smoothly take out the
retractable pen 100, the user must apply the force F1 to thecap 130 first. As shown inFIG. 4 toFIG. 6 , when the force F1 is applied to thecap 130, thecap 130 is moved toward thehousing 100 first to deform (compress) theelastic member 150. At this time, the second tooth portion G2 leans against the third tooth portion G3 to push the third tooth portion G3 away from the auxiliary tooth portion G1 a. That is to say, at this time, the drivingmember 140 is driven by thecap 130 to be pushed away from thefirst ratcheting structure 121 of theshaft 120. At the same time, the first tooth portion G1, the second tooth portion G2 and the third tooth portion G3 are all abutting slopes inclined with respect to the axis X1, and these abutting slopes have a uniform inclination tendency and are all substantially oriented toward a direction D1. That is to say, in the direction D1, an axial length of one side of a previous first tooth portion G1 adjacent to a previous auxiliary tooth portion G1 a along the axis X1 is greater than an axial length of one side of the previous first tooth portion G1 adjacent to a previous first groove portion L1 along the axis X1, and a length of one side of a next first tooth portion G1 adjacent to the previous first groove portion L1 is greater than a length of one side of the next first tooth portion G1 adjacent to a next auxiliary tooth portion G1 a. Therefore, in the state in which the force F1 is continuously applied, the drivingmember 140 is rotated in the direction D1 and provides a blocking effect, so that the third tooth portion G3 passes through the first tooth portion G1 (as shown inFIG. 6 ) to rotate to a position aligned with the first groove portion L1. That is, as shown inFIG. 6 , the third tooth portion G3 at this time is also regarded as being blocked by the next first tooth portion G1. Here,FIG. 4 toFIG. 6 are defined as a third state in which the driving member undergoes the switching process. - Then, with reference to
FIG. 7A toFIG. 7C , when the third tooth portion G3 of the drivingmember 140 is aligned with the first groove portion L1 and when the force F1 is released, theelastic member 150 then drives the drivingmember 140 to move into the first groove portion L1 along the axis X1. As described above, thesecond ratcheting structure 131 of thecap 130 and thefirst ratcheting structure 121 of theshaft 120 are slidably engaged with each other. Therefore, when the third tooth portion G3 of the drivingmember 140 is moved in the first groove portion L1 of thefirst ratcheting structure 121, the third tooth portion G3 leans against the second tooth portion G2 of thesecond ratcheting structure 131 of thecap 130. That is, the third tooth portion G3 and the second tooth portion G2 are both moved in the first groove portion L1. In this way, when theshaft 120 and thehousing 110 are fixed to each other, the drivingmember 140 may then be driven by theelastic member 150 to push thecap 130 away from thehousing 110. Theretractable pen 100 is thereby switched to the second state (extending state), and as shown inFIG. 1B andFIG. 1D , the user may then take out theretractable pen 100 from the portableelectronic device 20 by gripping thecap 130. - With reference to
FIG. 2C ,FIG. 7B andFIG. 7C again, in this embodiment, thefirst ratcheting structure 121 of theshaft 120 also has a blockingportion 121 a positioned at one end of the first groove portion L1 away from one end of thehousing 110. In the second state, the third tooth portion G3 leans against the second tooth portion G2 to push thecap 130 away from thehousing 110 until an abuttingportion 142 of the drivingmember 140 leans against the blockingportion 121 a, thereby completing the action of moving thecap 130 away from thehousing 110. - On the other hand, when the
retractable pen 100 is to be restored to the first state (that is, when theretractable pen 100 is to be accommodated back into the portable electronic device 20), the user at this time only needs to apply the force F1 to thecap 130 again, so that the drivingmember 140 is rotated in the direction D1 again as shown in the foregoing process ofFIG. 4 toFIG. 6 , and the third tooth portion is switched and leans against the second tooth portion G2 and the auxiliary tooth portion G1 a. However, at this time, the third tooth portion G3 is moved from the first groove portion L1 to the next auxiliary groove portion L1 a, so that theretractable pen 100 may be restored to the first state as shown inFIG. 3A toFIG. 3C . - To summarize, in the retractable pen of the embodiment of the disclosure, owing to the cooperation between the driving member and the elastic member, and depending on whether the first ratcheting structure of the shaft, the second ratcheting structure of the cap and the third ratcheting structure of the driving member lean against one another or not, the cap of the retractable pen may be moved away from the housing so that the retractable pen is switched to the extending state, or the cap may be moved toward the housing so that the retractable pen is switched to the retracting state. In this way, through the extending and retracting states of the retractable pen, the retractable pen may either be accommodated in the portable electronic device or be easily taken out from the portable electronic device.
