Abstract
Description
[0001] This invention relates to a pen, comprising a pen refill with a working end, a housing, an electrical connection device, a cap device, and a first moving device for moving the pen refill relative to the housing between two positions, namely,
[0002] a) First position, in which the working end of the pen refill is located in the housing, and
[0003] b) Second position, in which the working end of the pen tip extends from the housing, and
[0004] The second moving device is used to move the cover device relative to the electrical connection device between two positions, namely
[0005] a) In the first position, the cover device exposes the electrical connection device, and
[0006] b) Second position, in which the cover device covers the electrical connection device.
[0007] The type of pen mentioned in the introduction is known. Electrical connections are used, for example, for data transfer or to charge a rechargeable battery housed within the pen. In many regions, a USB-C port is specified as the electrical connection in this case. For example, this applies to the European Economic Area from the end of 2024. On the electronic device side, the connection is a receptacle conforming to the USB 3.0 Promotion Group's "Universal Serial Bus Type-C Cable and Connector Specification" standard. This receptacle consists of a recess with a centrally located tongue on either side, bearing electrical contacts. Especially when the pen is stored in a bag with other items, this recess can become clogged with dirt and dust, hindering reliable electrical contact. Therefore, a cover device is provided. For pens with a locking tension mechanism for retracting and extending the refill—common in ballpoint pens, for example—the situation becomes more complex: actuation of the locking tension mechanism causes not only longitudinal displacement of the refill but also longitudinal displacement of other internally arranged components. If the associated circuitry or electronic circuitry is part of these internal components, and if the recess in the housing for inserting the charging plug into the socket is not large enough, for example, to allow such relative movement, the force applied when retracting and extending the pen refill may adversely affect or damage the circuitry or electronic circuitry.
[0008] In view of the above problems, the object of the present invention is to avoid such adverse effects on the internal components of the pen when the first moving device is actuated.
[0009] According to the present invention, for such pens mentioned in the introduction, the objective is achieved by locking the first moving device to prevent the pen tip from moving relative to the housing when the cap device is in a first position relative to the electrical connection device.
[0010] In other words, when the electrical connection device is not covered by the cover and is exposed, thus creating the possibility of cables or the like being connected to the electrical connection device, the purpose is to prevent the electrical connection device from shifting within the housing, and therefore to prevent parts of the housing from impacting the cables or the like connected to the connection device. This is because such an impact could cause a reaction force, adversely affecting or damaging the internal components of the pen.
[0011] According to the invention, locking the first moving device to prevent the pen refill from moving relative to the housing can be achieved in any manner. However, according to the invention, a second moving device is preferably provided, comprising a stop in a second position of the cap assembly, the stop being located in the path along which the detent travels when the pen refill moves from the first position to the second position, the detent being coupled to the pen refill in the longitudinal direction of the pen.
[0012] In other words, by impacting the stop, the locking member prevents the first moving device from being actuated to extend the pen tip, so that none of the internal components of the pen can be displaced.
[0013] The locking element can be attached to the insert, which is connected to the pen refill in the longitudinal direction of the pen but can be displaced relative to the housing.
[0014] Inserts can be used for a variety of additional purposes, such as holding pen refills, accommodating rechargeable batteries or accumulators, or housing circuits or electronic circuits.
[0015] According to the present invention, preferably, the housing includes a stop.
[0016] Therefore, there is no need to provide additional parts for the stop and locking mechanism.
[0017] According to the invention, the second moving device can be actuated in any manner. However, according to the invention, it is preferable to provide an actuating device for the second moving device that is rotatable relative to the housing about the longitudinal axis of the pen and is connected to the cap device in the direction of rotation.
[0018] When the actuating device rotates relative to the housing about the longitudinal axis of the pen, the cover device shifts between two positions: a first position (in which the cover device exposes the electrical connection device) and a second position (in which the cover device covers the electrical connection device).
[0019] According to another preferred embodiment of the invention, an actuating device is provided in which the locking member is coupled to the second moving device in the rotational direction about the longitudinal axis of the pen, and is displaceable relative to the housing in the longitudinal direction of the pen.
[0020] Thus, when the actuating device and therefore the second moving device are actuated, the locking member moves in the rotational direction such that—as seen in the longitudinal direction of the pen—the locking member is located in front of the stop and therefore cannot be displaced in the longitudinal direction of the pen; or the locking member is located beside the stop and therefore can be displaced in the longitudinal direction when the first moving device is actuated.
[0021] According to another preferred embodiment of the invention, a locking member impacts the cover device when the second moving device is actuated.
[0022] The rotational connection between the locking element and the cover device can therefore be achieved in a particularly simple way.
[0023] The first moving device can be a locking tensioning mechanism, as commonly found in ballpoint pens.
[0024] Finally, according to the present invention, the preferred electrical connection device is a socket.
[0025] The invention will now be explained in more detail based on preferred embodiments and with reference to the accompanying drawings, in which:
[0026] Figure 1 A schematic diagram of a pen in two different operating positions according to a preferred embodiment of the present invention is shown.
[0027] Figure 2 It shows that according to Figure 1 A partial sectional view of the pen.
[0028] Figure 3 It shows that according to Figure 1 The back shell component of the pen,
[0029] Figure 4 It shows that according to Figure 1 The pen's actuation mechanism.
[0030] Figure 5 It shows that according to Figure 1 The pen insert, and
[0031] Figure 6 The assembly state is shown according to Figure 4 Actuation device and according to Figure 5 Inserts.
[0032] The pen shown in the attached figure includes a front housing component 1, which is implemented as a grip; and a rear housing component 2, which is implemented as a tubular shaft. The two housing components 1 and 2 are securely connected to each other, for example by a threaded connection.
[0033] The pen also includes an actuation device 3, which is implemented as a stopper and is rotatable about the pen's longitudinal axis L relative to the housing components 1 and 2. The pen tip 4, having a working end 41, is arranged in the housing.
[0034] An insert 5 is also provided in the housings 1 and 2, which accommodates the pen refill 4 and the circuit (not shown). Both the pen refill 4 and the circuit can be moved along the longitudinal axis L inside the housings 1 and 2 together with the insert 5.
[0035] To move the insert 5 containing the pen refill 4 and circuitry in the longitudinal direction of the pen, a moving device 6 is used. In the case of the pen shown in the attached figure, this moving device 6 is implemented in the form of a locking tensioning mechanism. Locking tensioning mechanisms have long been used, for example, to move the pen refill in ballpoint pens, and therefore the moving device 6 will not be described in more detail.
[0036] Button 7 is used to actuate the moving device 6.
[0037] In order to connect the circuit to an external device, an electrical connection device 8 is used, which is implemented as a USB socket in the case of the pen shown in the attached figure.
[0038] The rear housing component 2 is formed with a stepped wall thickness, thereby forming a stop 21. This step is indicated by reference numeral 22 in the attached drawing.
[0039] In addition, the rear housing component 2 has ribs 23 for connecting to the actuator 3.
[0040] The opening in the rear housing component 2 is indicated by reference numeral 24.
[0041] The actuating device 3 is provided with a clip 31 and a rib 32, the rib 32 being adapted to the rib 23 of the rear housing component 2. Therefore, the actuating device 3 can be connected to the rear housing component 2 in the axial direction, but can remain rotatable relative to the rear housing component 2 about the longitudinal axis L.
[0042] A cover device 33 in the form of a protective cover is formed on the actuating device 3.
[0043] The insert 5 has a carrier 52 that carries a flanged locking member 51 and another flange 53. In the assembled state, the locking member 51 and the flange 53 connect the cover device 33 to the insert 5 in the rotational direction about the longitudinal axis L. The insert 5 is thus connected to the actuating device 3 in the rotational direction, but can still move longitudinally within the housings 1 and 2. The actuating device 3, the stop 21, the locking member 51, and the flange 53 form a moving mechanism for the cover device 33.
[0044] The insert 5 is biased in the rearward direction by means of an elastic element (e.g., a spring (not shown)).
[0045] Figure 1 A is shown as a pen with a moving device 6 in a first position, in which the working end 41 of the pen tip 4 is located in the housings 1 and 2. Figure 1In position a, the other moving devices 3, 21, 51, and 53 are also in the first position. In the first position, the cover device 33 exposes the opening 24 and thus exposes the electrical connection device 8. In this position, the moving device 6 cannot be actuated because when an attempt is made to press the button 7 and thus move the insert 5 in the direction of the longitudinal axis L, the locking member 51 strikes the stop member 21.
[0046] exist Figure 1 The situation is different at position b. Figure 1 The position shown in b, and Figure 1 Compared to the position shown in Figure a, the actuating device 3 rotates relative to the housings 1 and 2, such that not only is the clip 31 positioned above the opening 24, but the cover device 33 also covers the electrical connection device 8. Only in this position of the moving devices 3, 21, 51, and 53 can the insert 5, and therefore the pen refill 4 and the electrical connection device 8, be axially displaced, because the locking member 51 does not impact the stop member 21.
[0047] When the electrical connector 8 is exposed and a plug may therefore be connected to it, the above-described configuration prevents the electrical connector 8 from shifting relative to the opening 24 and prevents the plug or the like from potentially striking the edge of the opening—which could damage the plug, the electrical connector 8, or the circuitry in the insert 5. Conversely, the possibility of axial displacement of the electrical connector 8 exists only at the location where the cover device 33 covers the electrical connector 8, and therefore no plug or the like can be inserted into the electrical connector 8. The plug, the electrical connector 8, and the circuitry are thus protected from such adverse effects and damage.
[0048] The features of the invention disclosed in the foregoing description, claims and drawings, whether alone or in any combination, are essential for carrying out the invention in its various embodiments.
