五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係一種傘具，尤指一種自動開收傘安全結構。 【先前技術】 [0002] 自動開收傘由於只需重複按壓同一個按鈕，就可以完 成自動開傘及自動收傘的動作，省去了用雙手方能將傘 打開或收起的麻煩，使用起來非常方便’因此一經問世 就廣受大眾喜愛。 自動開收傘内部的典型結構可參閱2002年2月13曰授 權公告的，公告號為CN2476208Y的中國實用新型專利， 其公開了一種“自動開收傘的控制裝置”。該自動開收 傘的動作原理是：當欲將傘打開時，向下按壓按鈕60’ ’使傘中棒5 0 ’失去控制裝置的控制，傘中棒5 0 ’内部 的開傘彈簧51’釋放能量，將傘中棒50’向上彈伸，使 傘打開；而當欲將傘收起時，再次向下按壓按钮60’ ， 使傘中棒50’内的扣頭523’也失去控制裝置的控制，扣 頭523’呈釋放狀態，在傘面骨架上的收傘彈簧（圖中未 示出）的彈力作用下，使傘面呈收傘狀態，扣頭523，則 由拉繩522’拉回到傘中棒50’上方；此時還處於未完全 收傘狀態’要達到完全收傘，還要再用力將傘面部分向 握柄110，處推動，使傘中棒50’縮短，開傘彈簧51，重 新積蓄能量’傘中棒5〇，及扣頭523’重新受握柄11〇’ 内的控制裝置控制，這樣傘具才完全呈收折狀態。 現有的自動開收傘的動作原理，基本上與上述專利前 案相同，例如申請號為：〇121 7730 ·Χ、01237609.4、 表單編號Α0101 第3頁/共14頁 M383324 0 1 262761. 5、03267824. X等等中國實用新型專利，所 不同的大都是握柄内部的用於控制傘中棒及扣頭的控制 裝置。 然而，現有自動開收傘雖然操作方便，但卻存在安全 隱患。具體原因如下：由於傘中棒内安裝有開傘彈簀， 開傘彈簧負責在打傘時將傘自動彈開，因此其彈性力較 大。當傘面已收起，需要按壓傘面部位元元到握柄位置 時，必須克服開傘彈簧的彈性力，而且必須按壓到位方 能將傘完全收起。但是由於開傘彈簧的彈性力很大，在 按壓過程中常會出現由於無力而鬆開的現象，此時傘中 棒還會自動迅速地彈開，在傘中棒彈開的過程中，由於 開傘彈簧的彈力很大，很容易發生意外而傷人，國外就 出現過由於收傘時傘中棒還未復位就又自動彈開而傷人 的事故。為此如何解決在收傘過程中，防止伞中棒還未 復位又自動彈開的問題，成為目前業者需要研究的課題 ---- 【新型内容】 [0003] 本創作所要解決的技術問題在於提供一種自動開收傘 安全結構，而可防止自動開收傘在收傘時，伞中棒意外 彈開的現象。 為解決上述技術問題，本創作的技術解決方案是： 一種自動開收伞安全結構，其設置於傘具握柄内的主 體内部，包括轉轴、棘輪、發條、定位塊及拉繩；該轉 軸軸柩於主體底部，其一端固定棘輪，另一端固定發條 ，棘輪上設有若干棘齒，發條的外端固定在主體上；該 表單編號A0101 第4頁/共14頁 M383324 定位塊一端樞接在主體上，自由端與棘輪的棘齒相對， 定位塊内側設有凸塊，凸塊從主體側壁上的一側孔伸入 到主體的軸孔内，並與傘中棒内設置的扣頭縮回時的位 置相對；所述拉繩一端固定在轉軸上，另一端固定在傘 頂端的上巢上。 所述定位塊與握柄的内壁之間設有可令定位塊自由端 復位抵頂於棘輪棘齒上的復位彈片。 所述扣頭上開一通孔，拉繩由該通孔穿過。 採用上述方案後，由於本創作在傘具握柄的内部設置 了安全結構，當收傘而令傘中棒在縮短的過程中，拉繩 的下端在發條的彈性力作用下不斷繞於轉軸上，如果按 壓於傘中棒上的力量消失，拉繩將欲帶動轉軸反轉，此 時，由定位塊的自由端抵入棘輪的棘齒，以防止轉軸反 轉，從而使拉繩拉住傘上巢，防止傘中棒向外彈開。也 就是說本創作利用棘輪的單向性，當收傘時，傘中棒只 可向下回縮，一旦向下回縮的力消失，即可隨時由拉繩 拉住傘中棒，防止在收傘的過程中，因對傘中棒的下壓 力消失，而意外彈開傷人的事故發生，令自動開收傘的 使用更具安全性。 【實施方式】 [0004] 下面結合附圖和具體實施例對本創作作進一步詳述。 本創作所揭示的是一種自動開收傘安全結構，如第二 圖及第三圖所示，為本創作的較佳實施例。本創作所述 的安全結構是設置於傘具握柄11内的主體2内部，其主要 包括轉軸3、棘輪4、發條5、定位塊6、復位彈片7及拉繩 表單編號A0101 第5頁/共14頁 M383324 8。其中： 所述的握柄11及其内的主體2内設置控制裝置，由於 控制裝置不是本案重點，因此圖中未示出。所述的主體2 内開有軸孔21用以安裝傘中棒12，傘中棒12内設有扣頭9 〇 所述轉軸3軸樞於主體2的底部，其一端固定有棘輪4 ，一端固定有發條5，發條5的外端固定在主體2上。所述 棘輪4上設有若干棘齒41，所述發條5的作用是可使轉軸3 具有轉動的趨勢。 所述的定位塊6 —端樞接在主體2上，異於樞接端的自 由端61與棘輪4的棘齒41相對。該定位塊6内側設有凸塊 62，該凸塊62從主體2側壁上的側孔22伸入到主體2的軸 孔21内，並與扣頭9縮回時的位置相對。 所述的復位彈片7設置於定位塊6與握柄11的内壁之間 〇 所述的拉繩8—端固定在上述轉軸3上，另一端固定在 傘頂端的上巢（圖中未示出）上。為了防止拉繩8隨意走 動，可在扣頭9上開一通孔91，令該拉繩8穿過該通孔91 〇 當傘面被收起之後，所述扣頭9被拉入到伞中棒12的 上方。當進一步按壓傘中棒12，使其縮短以令傘完全收 起的過程中，如第三圖所示，傘中棒12在縮短的過程中 ，所述拉繩8的下端在發條5的彈性力作用下不斷繞於轉 軸3上，而一旦按壓於傘中棒12上的力量消失，拉繩8將 欲帶動轉軸3反轉，此時，定位塊6的自由端61在復位彈 片7的彈力作用下抵入棘輪4的棘齒41，防止轉軸3反轉， 表單編號A0101 第6頁/共14頁 從而使拉繩8拉住傘的上巢，防止傘中棒12在開傘彈簧（ 圖中未示出）的作用而彈開，因此可防止傘中棒因意外 彈開而傷人的事故。 當傘中棒12縮短到預期的長度，使傘處於完全收起狀 態時，如第四圖所示，所述的扣頭9處於回縮至握柄11内 部的狀態，並受控制裝置的控制（不是本案重點，圖中 未示出）。此時扣頭9與定位塊6的凸塊62相對並抵頂凸 塊62，將定位塊6向外推出，使定位塊6的自由端61脫離 棘輪4的棘齒41。同時，所述的拉繩8繞於所述轉軸3上。 由於此時，定位塊6受扣頭9抵頂不與棘輪4的棘齒41相接 觸，因此當開傘時，棘輪4不會限制拉繩8拉長，傘可順 利打開，如第五圖所示。 本創作利用自動開收傘内都有的結構，即扣頭9來解 除定位塊6對棘輪4的轉動限制，以防止出現由於棘輪4被 定位塊6限制而令拉繩8無法拉長，進而使傘不能打開的 現象。而本創作也可以通過其他的控制結構解除定位塊 對棘輪的轉動限制。 【圖式簡單說明】 [0005] 第一圖係現有自動開收傘握柄内結構示意圖。 第二圖係本創作的立體分解圖。 第三圖係本創作的組合剖視圖（收傘過程狀態）。 第四圖係本創作的組合剖視圖（傘完全收起狀態）。 第五圖係本創作的組合剖視圖（傘打開狀態）。 【主要元件符號說明】 [0006] 60’按鈕 50’傘中棒 51’開傘彈簧 表單编號A0101 第7頁/共14頁 M383324 523’扣頭 522’拉繩 110’握柄 11握柄 12傘中棒 2主體 21轴孔 22側孔 4棘輪 41棘齒 6定位塊 61自由端 7復位彈片8拉繩 3轉軸 5發條 62凸塊 9扣頭 91通孔 表單編號A0101 第8頁/共14頁V. New description: [New technology field] [0001] This creation is an umbrella, especially an automatic umbrella opening safety structure. [Prior Art] [0002] Since the automatic opening and closing umbrella only needs to repeatedly press the same button, the automatic opening and automatic umbrella closing operation can be completed, and the trouble of opening or closing the umbrella with both hands can be eliminated. It is very convenient to use, so it has been widely loved by the public. The typical structure inside the automatic opening and closing umbrella can be referred to the Chinese utility model patent of CN2476208Y, which is published on February 13, 2002. It discloses a "control device for automatic opening and closing of umbrellas". The action principle of the automatic opening and closing umbrella is: when the umbrella is to be opened, the button 60'' is pressed down to make the control rod 5 0 of the umbrella lose control of the control device, and the open umbrella spring 51' inside the umbrella rod 50' Release the energy, stretch the stick 50' upwards in the umbrella to open the umbrella; and when the umbrella is to be stowed, press the button 60' down again, so that the buckle 523' in the rod 50' of the umbrella also loses the control device. The control, the buckle 523' is released, and under the elastic force of the umbrella spring (not shown) on the umbrella frame, the umbrella surface is in an umbrella state, and the buckle 523 is pulled by the rope 522' Pull back to the top of the umbrella 50'; at this time, it is still in the state of not fully closing the umbrella. In order to reach the full umbrella, the force of the umbrella surface is pushed to the handle 110, and the rod 50' is shortened. The umbrella spring 51 re-accumulates the energy 'the umbrella rod 5 〇, and the buckle 523' is again controlled by the control device in the grip 11 〇 ', so that the umbrella is completely folded. The operation principle of the existing automatic opening and closing umbrella is basically the same as the above patent application, for example, the application number is: 〇121 7730 ·Χ, 01237609.4, form number Α0101, page 3/14 pages M383324 0 1 262761. 5,03267824 X and other Chinese utility model patents, the difference is mostly the control device inside the handle for controlling the rod and the buckle in the umbrella. However, although the existing automatic opening and closing umbrella is convenient to operate, it has a safety hazard. The specific reasons are as follows: Since the umbrella rod is installed in the rod, the umbrella spring is responsible for automatically opening the umbrella when the umbrella is hit, so the elastic force is relatively large. When the canopy has been folded and the element of the canopy is pressed to the position of the handle, the elastic force of the open spring must be overcome, and the umbrella must be pressed in place to completely close the umbrella. However, due to the large elastic force of the open-spring spring, the phenomenon of loosening due to the lack of force often occurs during the pressing process. At this time, the rod in the umbrella will automatically pop open quickly, during the opening of the rod in the umbrella, due to the opening The elastic force of the umbrella spring is very large, and it is easy to cause accidents and hurt people. In foreign countries, there have been accidents that caused the rods in the umbrella to be automatically opened and wounded when the umbrella was closed. For this reason, how to solve the problem of preventing the rod in the umbrella from being reset and automatically bounced in the process of collecting the umbrella has become a subject that the current industry needs to study----[New content] [0003] The technical problem to be solved by this creation lies in The utility model provides an automatic opening and closing umbrella safety structure, which can prevent the automatic opening and closing of the umbrella in the umbrella when the umbrella is unexpectedly opened. In order to solve the above technical problems, the technical solution of the present invention is: an automatic opening and closing umbrella safety structure, which is disposed inside the main body of the umbrella grip, and includes a rotating shaft, a ratchet, a spring, a positioning block and a pulling rope; The shaft is fixed to the bottom of the main body, and the ratchet is fixed at one end, the spring is fixed at the other end, and a ratchet is arranged on the ratchet. The outer end of the spring is fixed on the main body; the form number A0101 is 4/14 M383324 positioning block One end is pivotally connected to the main body, and the free end is opposite to the ratchet of the ratchet. The inner side of the positioning block is provided with a convex block, and the convex piece protrudes from a side hole on the side wall of the main body into the shaft hole of the main body, and is arranged inside the rod of the umbrella. The position of the buckle is reversed when the buckle is retracted; the one end of the pull cord is fixed on the rotating shaft, and the other end is fixed on the upper nest of the top end of the umbrella. A reset spring piece is disposed between the positioning block and the inner wall of the handle to reset the free end of the positioning block against the ratchet ratchet. A through hole is opened in the buckle, and the drawstring passes through the through hole. After adopting the above scheme, since the creation has a safety structure inside the umbrella grip, when the umbrella is closed and the rod in the umbrella is shortened, the lower end of the rope is continuously wound around the shaft under the elastic force of the spring. If the force on the rod in the umbrella disappears, the drawstring will drive the shaft to reverse. At this time, the free end of the positioning block is inserted into the ratchet of the ratchet to prevent the shaft from being reversed, thereby pulling the drawstring. The nest on the umbrella prevents the rod from popping outwards. That is to say, the creation utilizes the unidirectionality of the ratchet. When the umbrella is closed, the rod in the umbrella can only be retracted downward. Once the downward retracting force disappears, the umbrella can be pulled by the drawstring at any time to prevent In the process of collecting the umbrella, the accident of the accidental bouncing of the person due to the disappearance of the downward pressure on the rod in the umbrella makes the use of the automatic opening and closing umbrella more secure. [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The present invention discloses an automatic opening and closing umbrella safety structure, as shown in the second and third figures, which is a preferred embodiment of the creation. The security structure described in the present invention is disposed inside the main body 2 in the umbrella grip 11, and mainly includes a rotating shaft 3, a ratchet 4, a spring 5, a positioning block 6, a reset elastic piece 7, and a pull cord form number A0101. / Total 14 pages M383324 8. Wherein: the handle 11 and the main body 2 therein are provided with control means. Since the control device is not the focus of the present case, it is not shown in the drawing. The main body 2 has a shaft hole 21 for mounting the umbrella rod 12, and the umbrella rod 12 is provided with a buckle 9 〇 the shaft 3 pivots to the bottom of the main body 2, and a ratchet 4 is fixed at one end thereof. A spring 5 is fixed, and the outer end of the spring 5 is fixed to the main body 2. The ratchet 4 is provided with a plurality of ratchet teeth 41, which function to make the rotating shaft 3 have a tendency to rotate. The positioning block 6 is pivotally connected to the main body 2, and the free end 61 of the pivoting end is opposite to the ratchet 41 of the ratchet 4. The inner side of the positioning block 6 is provided with a projection 62 which projects from the side hole 22 in the side wall of the main body 2 into the shaft hole 21 of the main body 2 and is opposite to the position at which the buckle 9 is retracted. The reset elastic piece 7 is disposed between the positioning block 6 and the inner wall of the handle 11. The pull cord 8 is fixed on the rotating shaft 3 at the end, and the other end is fixed on the upper nest of the umbrella top (not shown in the figure). )on. In order to prevent the pull cord 8 from moving freely, a through hole 91 can be opened in the buckle 9 so that the pull cord 8 passes through the through hole 91. After the umbrella surface is taken up, the buckle 9 is pulled into the umbrella. Above the stick 12. When the umbrella rod 12 is further pressed to be shortened so that the umbrella is completely stowed, as shown in the third figure, the lower end of the pull cord 8 is in the spring 5 during the shortening process. The elastic force is continuously wound around the rotating shaft 3, and once the force pressed on the rod 12 in the umbrella disappears, the pulling rope 8 will drive the rotating shaft 3 to reverse, and at this time, the free end 61 of the positioning block 6 is in the reset elastic piece 7. The ratchet 41 of the ratchet 4 is pressed by the elastic force to prevent the rotation shaft 3 from being reversed, and the form number A0101 is 6 pages/14 pages so that the pull cord 8 is pulled over the upper nest of the umbrella, and the umbrella rod 12 is prevented from being open at the umbrella spring ( It is bounced off by the action of the figure, so that it can prevent an accident in which the rod in the umbrella is wounded by accidental bounce. When the rod 12 in the umbrella is shortened to the expected length so that the umbrella is in the fully stowed state, as shown in the fourth figure, the buckle 9 is in a state of being retracted to the inside of the grip 11, and is controlled by the control device. (Not the focus of this case, not shown in the figure). At this time, the buckle 9 is opposed to the projection 62 of the positioning block 6 and abuts against the projection 62, and the positioning block 6 is pushed outward to disengage the free end 61 of the positioning block 6 from the ratchet 41 of the ratchet 4. At the same time, the drawstring 8 is wound around the rotating shaft 3. At this time, the positioning block 6 is not in contact with the ratchet teeth 41 of the ratchet 4 by the buckle 9 so that when the umbrella is opened, the ratchet 4 does not restrict the extension of the drawstring 8 and the umbrella can be smoothly opened, as shown in the fifth figure. Shown. The present invention utilizes the structure of the automatic opening and closing umbrella, that is, the buckle 9 to release the rotation restriction of the ratchet 4 by the positioning block 6 to prevent the pulling rope 8 from being elongated due to the restriction of the positioning block 6 by the ratchet 4, and further The phenomenon that the umbrella cannot be opened. However, this creation can also remove the rotation limit of the positioning block to the ratchet through other control structures.
