1274564 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種塗布器裝置,其包括: 一殼體, 一儲存裝置,其用於儲存將被塗布之物品, 一塗布裝置,其包括一被可旋轉地保持於一球座中之球 體, 一密封裝置,其可沿著位在一相對於該殻體的第一位置 鲁及一相對於該殼體的第二位置之間的一預定路徑而移動,而 在該第一位置中,該密封裝置密封地抵住該球體,且在該第 二位置中’該密封裝置釋放該球體以利該物品之塗布,及 一增大壓力產生裝置,其用於在該儲存裝置中產生一增 大之壓力,其中 該密封裝置在該路徑之一預定部分中被耦接至該增大 壓力產生裝置。 【先前技術】 φ 該前述種類之塗布器裝置係習知的,例如由EP 1 44 5 121 A1。 當在前述第一位置上之該密封裝置密封地承抵住該球 體時’其將驅使該球體進入該球座內,如此使得在該球座及 該球體間可形成一間隙,而該欲被塗布的物品在該儲存裝置 中獲得一增大之壓力後便可立即經由該間隙而排出。在習知 之塗布器裝置中,當該密封裝置從該第一位置進入至該第二 位置內之路徑的該預定部分,亦即在其中該密封裝置被耦接 1274564 至該增大壓力產生裝置處之路徑的那部分直接地毗鄰該第 一位置時,一增大之壓力將產生於該儲存裝置中,同時該球 體仍由該密封裝置推進至該球座內,因此而存在該物品逃漏 之風險。 【發明內容】 本發明之目的在於發展出如本說明書開頭部分所提出 之該類塗布器裝置,如此使得將欲被塗布之物品洩流出之風 險可被降低。 I 根據本發明,將可達成有關發展出如本說明書開頭部分 所提出之該類塗布器裝置之目的,因爲在由該第一位置所限 定之路徑的一第一部分中,該密封裝置與該增大壓力產生裝 置係獨立無關的。 換言之,該密封裝置從該第一位置處進入至該第二位置 內之路徑的那部分將不會直接毗鄰該第一位置,而其中該密 封裝置將被耦接至該增大壓力產生裝置處。確切地說,該密 封裝置與該增大壓力產生裝置之相耦接僅發生在該運動路 II徑之較後部分,因此只要該球體仍被該密封裝置推進入該球 座內以致使一間隙開啓於該球體及該球座間,便不改會有增 大之壓力被產生於該儲存裝置中。確切地說,在該儲存裝置 中之壓力的增大僅發生在當該密封裝置已離開該球體且該 前述之間隙已閉合之時。此將降低該欲被塗布之物品洩流出 之風險。 根據本發明之一較佳實施例,其提供一用以相對於該殼 體移動該密封裝置之螺紋。那形狀可藉由機械方式而特別容 1274564 易地予以成形體現。 此外或可選擇地,其亦可提供一卡銷連接。 在另一較佳特徵中,其提供一用於在該運動路徑之該預 定部分中使該密封裝置耦接該增大壓力產生裝置之耦接裝 置。更具體言之,此一耦接裝置允許在那路徑之該第一部分 中脫離耦合狀態。 在那情形下,該耦接裝置較佳地具有一第一耦接元件於 該密封裝置處以及一第二耦接元件於該增大壓力產生裝置 • 處,該等元件可經由一磨擦嚙合及/或經由一正鎖定嚙合而 被轉接在一起。 在那情形下,該兩耦接元件可被整體地分別設置在該密 封裝置處及在該增大壓力產生裝置處,或可呈一分離部分之 型式並被連接至該等組件上。 該耦接裝置可具有一齒環於該增大壓力產生裝置處及/ 或在該密封裝置處。 換言之,那形狀本質上需配合一正鎖定連接而操作。 # 此一正鎖定連接以及一磨擦連接兩者可被設計成使得 整個該配置可提供作爲一滑動離合器,例如以便可限制該產 生於儲存裝置中之壓力。 特別是在該齒環之情況中,其可依據本發明而被設置成 使得該耦接裝置具有至少一齒狀突出部於該密封裝置上及/ 或該增大壓力產生裝置上。 該齒環及/或該齒狀突出部較佳地係被設置在一套筒狀 突出部上,而該套筒狀突出部較佳地具有至少一縱向槽孔。 1274564 那設計形狀與一例如具有三齒環的設計形狀相較係爲 較佳的,因爲耦接嚙合較容易發生。 根據本發明之一尤其較佳之特徵,其被設置成使得該增 大壓力產生裝置可藉由一方式予以控制,如此導致可使該儲 存裝置中之壓力得以降低。 如此,在有關無洩漏防護方面是有利的。 根據本發明之另一較佳實施例,其被設置成使得該增大 壓力產生裝置包括一具有至少一母螺紋元件及至少一公螺 • 紋元件之傳動裝置,其中該傳動裝置可採取至少兩個操作狀 態,其分別係: 一第一操作狀態,其中該兩螺紋元件彼此嚙合以產生該 增大之壓力,及 一第二操作狀態,其中該等元件不相互嚙合,因而導致 在該增大壓力上之下降。 換言之,根據本發明之此一較佳實施例,其被設置成使 得兩螺紋元件被耦合在一起以產生該增大之壓力,及被脫離 修耦合以減小該儲存裝置中之壓力。那將提供一種解決方法, 其從結構之觀點而言係特別地簡單、不昂貴且易於操縱。 可能發生該塗布器裝置之一使用者在工作已完成之後 忘記降低該儲存裝置中之壓力。在此一情形中,於某些狀況 下,該欲被予塗布之物品可能在該儲存裝置中遭受損壞。此 外,亦無法確保該物品將不會洩流出。 根據本發明之一特別較佳實施例,其因此而被設置成使 得該塗布器裝置可採取至少兩個操作狀態,分別係一止動狀 1274564 態及一使用狀態,及具有一'用於減小該儲存裝置中之壓力的 裝置,該壓力減小裝置將因應該塗布器裝置從該使用狀態至 該止動狀態中之運動而反應。 換言之,本發明之此一形狀將可使得該儲存裝置中之壓 力在該塗布器裝置已完成其工作而被移動至該止動狀態後 可隨即被自動地降低。 在那觀點中,將被設置成使得該塗布器裝置可藉由將該 密封裝置相對於該殼體置於該第一位置中而處於該止動狀 φ 態下。 換言之,本發明之此一形狀將使該密封裝置可被置於該 .第一位置中,亦即進入該位置中以便密封地承抵住該球體, 而此將導致該儲存裝置中之壓力得自動地降低。 【實施方式】 參照第1圖,該筆體具有一外軸10,其可當作一殼體且 於其上在如第1圖所示之該操作位置(止動位置)處旋接一 蓋件1 2。爲達此功能而設置有一以參考號碼1 4表示之螺 φ紋。該蓋件12具有一密封件16,其在如第1圖所示之操作 狀Sg下幣封地環圍一*筆尖18。在該筆尖18之自由端處’ 一 球體20被固定在一球座2 1中,而該密封件1 6則密封地承 抵住該球體2 0。 該筆尖18在其遠離該球體20之端部處被一筆心套筒22 所封圍。該蓋件1 2以一在下文中將予詳細說明之方式部分 地以可旋轉之型式被耦接至該套筒22。 該套筒22之內部空間形成一墨水儲存裝置24。一封閉 1274564 塊28被配置在該儲存裝置24中之遠離該球體20的該側上, 其可用以相對於周遭大氣而達成封鎖狀態。該儲存裝置24 之後邊界係由一柱塞3 0所構成。該柱塞3 〇被可滑動地設置 在該儲存裝置24內。當從該球體處觀看時’一柱塞座32被 設置在該柱塞30之後方。一控制推桿34伸入該柱塞座內。 一彈簧3 6之一方面承抵住該控制推桿34,而另一方面則承 抵住一封閉蓋件38。 如第2圖處可見,該柱塞30具有一突出部40,其在已 φ 組裝之狀態下將會嚙合入一位在該柱塞座32中之窗口 42 內。該柱塞座32在其遠離該柱塞30之一端處具有突出部44 及46,其嚙合入位在該筆心軸22中之相對應凹部內,以便 可達成旋轉耦接之目的。因此,該柱塞座3 2被可旋轉地耦 接至該筆心軸22,但其係被軸向可滑動地固定於其中。 再者,該柱塞座32在其遠離該柱塞30之一端處配置有 一大體上呈半球狀之母螺紋元件48於其內部,而該母螺紋 元件48可用於有時耦接該控制推桿34。 • 該控制推桿34上設置有若干公螺紋元件,其與該母螺 紋元件48係呈互補相配的,且其中之一公螺紋元件被標示 以參考號碼50以作爲範例。該等公螺紋元件50相當於一螺 旋凹槽之諸部分,並分別地伸展在一稍大於3 00°之角度範 圍。該等公螺紋元件50被一伸展在一大約27。角度範圍之縱 向凹槽52所阻斷。 該控制推桿34在其遠離該壁部20之一端處配置有若千 突出部54、56、58及60,其嚙合入位在該外軸10中之相對 -10- 1274564 應凹部內,以便可達成旋轉耦接之目的。然而,該控制推桿 34相對於該外.係軸向可滑動於該封閉蓋件38及一基座 6 2之間。該圖中所示之筆體的功能如下: 第4圖至第7圖顯示該蓋件12相對於當作一殼體之該 外軸1 0的各種不同操作位置。 如特別地從第4圖至第7圖可見的,一呈套筒形狀之突 出部66被設置在該蓋件12之內部空間中,且其伸展超過該 密封件1 6並具有至少一縱向槽孔6 8。一系列齒狀突出部被 φ 設置在該突出部66之內側上,且其中之一齒狀突出部被標 示以參考號碼7〇以作爲範例。 •該套筒22載有一齒環72,其可與位在該突出部66上之 、 該等齒狀突出部70相匹配。 如前已提及的,第1圖顯示該筆體之止動位置,亦即指 其中該蓋件12被擰合至該當作殼體之外軸1〇上的那位置, 更具體而言乃因此而使該密封件1 6可密封地承抵住該球體 20。相同之位置(止動位置)亦被顯示於第4圖中。當此刻 #該蓋件12被從該外軸1 0處旋開時,該蓋件移向第4圖中之 左邊。在該移動路徑之一第一部分74中(第4圖),該等 齒狀突出部70並不與該齒環72相嚙合,該套筒22因此亦 將不會被該蓋件1 2所轉動。更確切地說,該等齒狀突出部 70僅在該蓋件12從該止動位置進入至該操作位置中之路徑 的較後部分75時才會與該齒環72相嚙合。在該位置上,該 密封件1 6已被上舉而脫離該球體20。那情況被顯示於第5 圖中。由於該等齒狀突出部70與該齒環72間之嚙合,該套 -11- 1274564 筒2 2此刻將連同該蓋件1 2 —起旋轉。 一部分78毗連該部分76,且在其中該等齒狀突出部70 再度離開該齒環7 2,如第6圖及第7圖所示。在該操作位置 上,該蓋件1 2相對於該外軸1 〇之進一步旋轉並不會導致該 套筒2 2之任何進一步旋轉運動。 在如第1圖所示之該操作位置(止動位置)上,亦即當 該蓋件12被擰合至該外軸1〇時,該母螺紋元件48係位於 該凹槽52中。因此,在該操作位置上,該控制推桿34及該 φ 柱塞3 0間並未耦合。該柱塞3 0因此不會施加予任何壓力至 該封閉塊28或墨水26上。 當該蓋件1 2被相對於該外軸1 〇而旋轉以便將其鬆開 時,由於接著之旋轉耦合效應尙未呈現在該蓋件1 2及該套 筒22之間,故在該蓋件12之運動路徑的該第一部分74中, 該柱塞座32並不會旋轉。該柱塞座32之旋轉運動首先發生 在該蓋件12之運動路徑的該部分76中,更特定言之此乃藉 由該等齒狀突出部70與該齒環72間的嚙合所致。在該旋轉 ϋ運動之進一步進程中,該母螺紋元件48將離開該凹槽52並 且進入該公螺紋元件5 0之內。在那狀況下之進一步旋轉運 動意指該母螺紋元件48係沿著該公螺紋元件50而行進,藉 以使得此刻已被支撐抵住該基座62之該控制推桿34對著該 彈簧3 6而被移動。結果,該彈簧3 6之彈性回復力經由該控 制推桿34而作用在該柱塞座32上,並因而作用在該柱塞30 上,藉以使得該儲存裝置24中之壓力上升。該公螺紋元件 50在其端部處被一接界64所限制,而在進一步之旋轉運動 -12- 1274564 發生後,該母螺紋元件4 8將立即抵接該接界6 4。在該圖式 所示之實施例中,該等尺寸被選定成使得該母螺紋元件48 可抵接該接界64,以便使該蓋件1 2可到達該部分7 8,其中 該等齒狀突出部70將不再與該齒環72相嚙合。 然而’有可能因製造公差而導致在正確配合上之困難 性。該縱向槽孔68因此而被設置。更具體言之,如果該母 螺紋兀件4 8接合抵住該接界6 4且同時該等齒狀突出部7 0 仍與該齒環72相嚙合,則該突出部66由於該縱向槽孔68 • 而可伸展’以致使該等齒狀突出部70可滑動於該齒環上(滑 動離合器)且因而可使該等齒狀突出部70及該齒環72不致 -被損壞。 . 於是在該儲存裝置24中已被增進之增大壓力可被用以 將該墨水26排出。該筆體此時便處於操作之位置。 在該筆體使用後,當該蓋件12再度被擰合至該外軸10 上時,由於該已詳述於前文中之位在部分7 6中的耦合效應 之故,使得該母螺紋元件48接著沿該公螺紋元件50運行而 鲁再度回到該凹槽52內。結果,在該彈簧36之影響作用下, 該控制推桿34再度推進至該基座62,而該控制推桿34便被 支撐於此處。因此,該彈簧36將不再經由該柱塞座32及該 柱塞30而作用在該墨水26上。在那狀況下,該儲存裝置24 中將不再獲得任何被增大之壓力,而由此所產生之重大優點 在於可藉由和緩作用而保護該墨水26及該封閉塊28以及在 於抗漏防護方面。 當該蓋件1 2被旋接至該外軸1 0上時,該柱塞座32被 -13- 1274564 移動遠離該球體20,直到該母螺紋元件48進入該凹槽52 內爲止。該柱塞3 0係呈一後置柱塞之型式,以致在此情況 下使得該柱塞30不會將該墨水從該筆尖18處吸出。更具體 言之’該柱塞座32可依據該窗口 42之軸向長度且在不承載 該柱塞30下移動遠離該球體20。 除了在該窗口 42中之突出部40外,或者爲取代在該窗 口 42中之突出部40,將亦可在該柱塞座32及該柱塞30之 間提供一彈性耦接裝置。 φ 然而’該彈性耦接裝置及/或該餘隙亦可被連接在該控 制推桿34及該用以限定儲存裝置24之柱塞表面間的其他 處。 第1圖至第3圖所示之旋轉傳動裝置可補償該儲存裝置 24中於塡充高度上之減低。更具體而言,由於一減低之塡充 高度,該柱塞座32將連同該柱塞30 —起逐漸地移入該儲存 裝置24之內,而該控制推桿34依據該塡充高度並不會改變 其相對於該彈簧3 6之位置,因此使得相等之回復力總是可 •獲得以甩於產生該增大之壓力。 該封閉蓋件3 8可以一減震器方式被彈性地固定。該彈 簧3 6可用以產生該彈性固定效應,亦即其回復力可用於產 生該儲存裝置24中之增大壓力的彈性元件者。此一形態從 而可將所涉組件之數量減至最少程度。 本發明揭示於前列說明、申請專利範圍及圖式中之特 徵,對於以單獨及任何組合型式實施該等不同實施例中之本 發明者而言,均係爲必要且不可或缺的。 -14- 1274564 【圖式簡單說明】 第1圖係一根據本發明之一特別較佳實施例所實施之一 筆體的縱向剖面視圖, 桌2圖顯不第1圖中之該筆體的一柱塞之諸視圖, 桌3圖顯不第1圖中之該筆體的一控制推桿之諸視圖, 第4圖至第7圖顯示該筆體與一蓋件間之配合狀態的諸 剖面示意圖,及 第8圖及第9圖顯示套有該蓋件之鉛筆的諸剖面示意 •圖。 【主要元件符號說明】 10 外軸 12 蓋件 14 螺紋 16 密封件 18 筆尖 20 球體 2 1 球座 22 套筒 24 儲存裝置 26 墨水 28 封閉塊 30 柱塞 32 柱塞座 34 控制推桿 -15- 12745641274564 IX. Description of the Invention: The present invention relates to an applicator device comprising: a housing, a storage device for storing articles to be coated, a coating device comprising a a ball rotatably held in a tee, a sealing device that is positionable between a first position relative to the housing and a second position relative to the housing Moving in a path in which the sealing device sealingly abuts the ball, and in the second position 'the sealing device releases the ball to facilitate application of the article, and an increased pressure generating device And for generating an increased pressure in the storage device, wherein the sealing device is coupled to the increased pressure generating device in a predetermined portion of the path. [Prior Art] φ This type of applicator device of the foregoing type is known, for example, from EP 1 44 5 121 A1. When the sealing device in the first position sealingly bears against the ball, 'it will drive the ball into the ball seat, so that a gap can be formed between the ball seat and the ball, and the The coated article is immediately discharged through the gap after obtaining an increased pressure in the storage device. In a conventional applicator device, when the sealing device enters from the first position to the predetermined portion of the path within the second position, that is, where the sealing device is coupled 1274564 to the increased pressure generating device When the portion of the path is directly adjacent to the first position, an increased pressure will be generated in the storage device while the ball is still advanced by the sealing device into the tee, thereby presenting the item to escape. risk. SUMMARY OF THE INVENTION It is an object of the present invention to develop such an applicator device as set forth in the opening paragraph of the present specification such that the risk of venting the article to be coated can be reduced. According to the present invention, it will be possible to achieve the object of developing such an applicator device as set forth in the opening paragraph of the present specification, because in a first portion of the path defined by the first position, the sealing device is The large pressure generating device is independent and independent. In other words, the portion of the sealing device that enters the path within the second position from the first position will not be directly adjacent to the first position, and wherein the sealing device will be coupled to the increased pressure generating device . Specifically, the coupling of the sealing device to the increased pressure generating device occurs only at a later portion of the path of the moving path II, so that as long as the ball is still pushed into the ball seat by the sealing device to cause a gap Opening between the sphere and the tee, no additional pressure is generated in the storage device. Specifically, the increase in pressure in the storage device only occurs when the sealing device has left the ball and the aforementioned gap has closed. This will reduce the risk of the item to be coated being vented. According to a preferred embodiment of the invention, a thread for moving the sealing device relative to the housing is provided. The shape can be easily formed by mechanical means and 1274564. Additionally or alternatively, it may also provide a bayonet connection. In another preferred feature, a coupling means for coupling the sealing means to the increased pressure generating means in the predetermined portion of the path of motion is provided. More specifically, the coupling device allows for the uncoupled state in the first portion of the path. In that case, the coupling device preferably has a first coupling element at the sealing device and a second coupling element at the increased pressure generating device, the components can be engaged via a friction / or transferred together via a positive locking engagement. In that case, the two coupling elements may be integrally disposed at the sealing device and at the increased pressure generating device, or may be in the form of a separate portion and connected to the components. The coupling device can have a toothed ring at the increased pressure generating device and/or at the sealing device. In other words, the shape essentially needs to operate in conjunction with a positive locking connection. # Both a positive locking connection and a frictional connection can be designed such that the entire configuration can be provided as a slip clutch, e.g., to limit the pressure generated in the storage device. In particular in the case of the toothed ring, it can be provided in accordance with the invention such that the coupling device has at least one toothed projection on the sealing device and/or the increased pressure generating device. Preferably, the ring gear and/or the toothed projection are provided on a sleeve-like projection, and the sleeve-like projection preferably has at least one longitudinal slot. 1274564 The design shape is preferred over a design shape such as a three-toothed ring because coupling engagement is more likely to occur. According to a particularly preferred feature of the invention, it is provided that the increased pressure generating means can be controlled in a manner which results in a reduction in the pressure in the storage means. As such, it is advantageous in terms of leak-free protection. According to another preferred embodiment of the present invention, the increased pressure generating device comprises a transmission having at least one female threaded member and at least one male threaded member, wherein the transmission can take at least two Operating states, respectively: a first operational state, wherein the two threaded members engage each other to produce the increased pressure, and a second operational state, wherein the components do not mesh with each other, thereby causing the increase The decline in pressure. In other words, in accordance with this preferred embodiment of the invention, it is arranged such that the two threaded members are coupled together to create the increased pressure and are disengaged to reduce the pressure in the storage device. That would provide a solution that is particularly simple, inexpensive and easy to manipulate from a structural point of view. It may happen that one of the applicator devices forgets to reduce the pressure in the storage device after the work has been completed. In this case, under certain conditions, the item to be coated may be damaged in the storage device. In addition, there is no guarantee that the item will not leak out. According to a particularly preferred embodiment of the invention, it is thus arranged such that the applicator device can assume at least two operating states, respectively a stop 1274564 and a use state, and have a 'for reduction A device that compresses the pressure in the device, the pressure reducing device reacting due to movement of the applicator device from the use state to the stop state. In other words, this shape of the invention will allow the pressure in the storage device to be automatically reduced immediately after the applicator device has completed its operation and moved to the detent state. In that regard, it will be provided that the applicator device can be in the stop state φ by placing the sealing device in the first position relative to the housing. In other words, this shape of the invention will allow the sealing device to be placed in the first position, i.e., into the position to sealingly bear against the ball, which will result in pressure in the storage device. Automatically lowered. [Embodiment] Referring to Figure 1, the pen body has an outer shaft 10 which can be used as a casing and is screwed onto the cover at the operating position (stop position) as shown in Fig. 1. Item 1 2. To achieve this function, a screw φ pattern indicated by reference numeral 14 is provided. The cover member 12 has a sealing member 16 which encloses a * nib 18 under the operation Sg as shown in Fig. 1. At the free end of the nib 18, a ball 20 is fixed in a ball seat 21, and the sealing member 16 is sealingly received against the ball 20. The nib 18 is enclosed by a core sleeve 22 at its end remote from the ball 20. The cover member 12 is partially coupled to the sleeve 22 in a rotatable manner in a manner that will be described in greater detail below. The interior of the sleeve 22 defines an ink reservoir 24. A closed 1274564 block 28 is disposed on the side of the storage device 24 remote from the ball 20, which can be used to achieve a blocked state relative to the surrounding atmosphere. The boundary of the storage device 24 is formed by a plunger 30. The plunger 3 is slidably disposed within the storage device 24. A plunger seat 32 is disposed behind the plunger 30 when viewed from the ball. A control push rod 34 extends into the plunger seat. One of the springs 36 bears against the control pusher 34 and on the other hand bears against a closure member 38. As can be seen in Figure 2, the plunger 30 has a projection 40 that will engage into a window 42 in the plunger seat 32 when assembled in the φ state. The plunger seat 32 has projections 44 and 46 at one end thereof away from the plunger 30 that engage in corresponding recesses in the pen mandrel 22 for the purpose of rotational coupling. Therefore, the plunger holder 32 is rotatably coupled to the pen shaft 22, but is axially slidably fixed therein. Moreover, the plunger holder 32 is disposed at one end thereof away from the plunger 30 with a substantially hemispherical female threaded member 48 therein, and the female threaded member 48 can be used to sometimes couple the control push rod 34. • The control push rod 34 is provided with a plurality of male threaded elements that are complementary to the female threaded element 48, and one of the male threaded elements is labeled with reference numeral 50 as an example. The male threaded elements 50 correspond to portions of a helical groove and extend respectively over an angular extent of slightly greater than 300°. The male threaded elements 50 are stretched at a level of about 27. The longitudinal extent of the angular extent is blocked by the groove 52. The control push rod 34 is provided at one end thereof away from the wall portion 20 with a plurality of protrusions 54, 56, 58 and 60 which are engaged in the recess -10- 1274564 in the outer shaft 10 so as to be Rotational coupling can be achieved. However, the control pusher 34 is axially slidable relative to the outer shaft between the closure member 38 and a base 62. The function of the pen body shown in the figure is as follows: Figures 4 to 7 show various different operating positions of the cover member 12 with respect to the outer shaft 10 as a casing. As can be seen in particular from Figures 4 to 7, a sleeve-shaped projection 66 is provided in the interior space of the cover member 12 and extends beyond the seal member 16 and has at least one longitudinal slot. Hole 6 8. A series of dentations are provided on the inner side of the projection 66 by φ, and one of the dentations is indicated by reference numeral 7 〇 as an example. • The sleeve 22 carries a toothed ring 72 that mates with the toothed projections 70 located on the projection 66. As already mentioned, Fig. 1 shows the stop position of the pen body, that is, the position in which the cover member 12 is screwed to the outer shaft 1 of the casing, more specifically The seal 16 thus sealably bears against the ball 20. The same position (stop position) is also shown in Figure 4. When the cover member 12 is unscrewed from the outer shaft 10 at this moment, the cover member is moved to the left in Fig. 4. In a first portion 74 of the moving path (Fig. 4), the toothed projections 70 do not engage the ring gear 72, and the sleeve 22 will therefore not be rotated by the cover member 12. . More specifically, the toothed projections 70 engage the toothed ring 72 only when the cover member 12 enters the rearward portion 75 of the path in the operative position from the detent position. In this position, the seal 16 has been lifted off the ball 20. That situation is shown in Figure 5. Due to the engagement of the toothed projections 70 with the ring gear 72, the sleeve -11-1227464 cylinder 2 2 will now rotate with the cover member 12. A portion 78 abuts the portion 76 and wherein the toothed projections 70 again exit the ring gear 7 2 as shown in Figures 6 and 7. In this operative position, further rotation of the cover member 1 2 relative to the outer shaft 1 并 does not result in any further rotational movement of the sleeve 2 2 . In the operating position (stop position) as shown in Fig. 1, that is, when the cover member 12 is screwed to the outer shaft 1 ,, the female thread member 48 is located in the recess 52. Therefore, in this operating position, the control push rod 34 and the φ plunger 30 are not coupled. The plunger 30 therefore does not apply any pressure to the closure block 28 or the ink 26. When the cover member 12 is rotated relative to the outer shaft 1 to release it, since the subsequent rotational coupling effect is not present between the cover member 12 and the sleeve 22, the cover is In the first portion 74 of the path of motion of the member 12, the plunger seat 32 does not rotate. The rotational movement of the plunger seat 32 first occurs in the portion 76 of the path of movement of the cover member 12, more specifically by the engagement of the toothed projections 70 with the ring gear 72. In the further progression of the rotary motion, the female threaded member 48 will exit the recess 52 and enter the male threaded member 50. Further rotational movement in that condition means that the female threaded member 48 travels along the male threaded member 50 such that the control pusher 34, which is now supported against the base 62, faces the spring 36. And being moved. As a result, the elastic restoring force of the spring 36 acts on the plunger seat 32 via the control push rod 34, and thus acts on the plunger 30, whereby the pressure in the storage device 24 rises. The male threaded element 50 is bounded at its end by an interface 64, which will immediately abut the junction 64 after further rotational movement -12-1274564 occurs. In the embodiment illustrated in the drawings, the dimensions are selected such that the female threaded member 48 can abut the interface 64 such that the cover member 12 can reach the portion 7 8, wherein the teeth are The projection 70 will no longer mesh with the ring gear 72. However, it is possible to make it difficult to properly fit due to manufacturing tolerances. This longitudinal slot 68 is thus provided. More specifically, if the female thread member 48 is engaged against the interface 64 and while the toothed projections 70 are still engaged with the ring gear 72, the projection 66 is due to the longitudinal slot 68 • It is extendable so that the toothed projections 70 can slide over the toothed ring (slip clutch) and thus the toothed projections 70 and the ring gear 72 can be prevented from being damaged. Thus, the increased pressure that has been enhanced in the storage device 24 can be used to discharge the ink 26. The pen is now in the operating position. After the pen body is used, when the cover member 12 is once again screwed onto the outer shaft 10, the female thread member is made due to the coupling effect in the portion 76 in the foregoing. 48 then travels along the male threaded member 50 and returns to the recess 52 again. As a result, under the influence of the spring 36, the control pusher 34 is again advanced to the base 62, and the control pusher 34 is supported there. Therefore, the spring 36 will no longer act on the ink 26 via the plunger seat 32 and the plunger 30. In that condition, any increased pressure will no longer be obtained in the storage device 24, and the significant advantage resulting therefrom is that the ink 26 and the closure block 28 can be protected by a gentle action and in the protection against leakage. aspect. When the cover member 12 is screwed onto the outer shaft 10, the plunger seat 32 is moved away from the ball 20 by -13-1274564 until the female threaded member 48 enters the recess 52. The plunger 30 is in the form of a rear plunger such that in this case the plunger 30 does not draw the ink from the nib 18. More specifically, the plunger holder 32 is movable away from the ball 20 in accordance with the axial length of the window 42 and without carrying the plunger 30. In addition to the projection 40 in the window 42, or instead of the projection 40 in the window 42, an elastic coupling means may be provided between the plunger 32 and the plunger 30. Φ However, the resilient coupling means and/or the clearance may also be coupled to the control push rod 34 and the other portion between the surfaces of the plungers for defining the storage means 24. The rotary transmission shown in Figures 1 to 3 compensates for the reduction in the charge height of the storage device 24. More specifically, due to a reduced charge height, the plunger holder 32 will progressively move into the storage device 24 along with the plunger 30, and the control pusher 34 will not depend on the charge height. The position relative to the spring 36 is changed so that an equal restoring force can always be obtained to produce the increased pressure. The closure cap 38 can be elastically fixed in a shock absorber manner. The spring 36 can be used to create the elastic fixation effect, i.e., its restoring force can be used to create an increased pressure elastic element in the storage device 24. This form thus minimizes the number of components involved. The invention disclosed in the foregoing description, the scope of the claims, and the features of the drawings are essential and indispensable to the present invention in the various embodiments.
