New description: [New technical field] The new type is about curtains, especially a safety curtain that can prevent the rope from causing danger around the neck. [Prior Art] Conventional venetian blinds usually use two drawstrings to control the vertical and overlapping of the blades, but since the bottom end of the drawstring is a ring-shaped free end, it is not only easy to generate noise due to wind blows and collisions with the lower rails and blades. It is also possible that the danger of getting around the neck is caused by the young children playing. The invention patent of kUS68〇2356 B2 (China Mainland Bulletin No. cn2609456) is claimed by the inventor, and the invention patent mainly includes, the upper holder U, a lower holder 12 parallel to the upper holder, and one erected thereon. The curtain unit 13 between the rail i! and the lower handle 12. The shade unit 丨3 includes a plurality of parallel blades 131, two guide sheaves 132 mounted on the upper rail U at intervals, a pull cord locator 133 mounted in the upper rail u, and two The drawstring 1〇, each of the drawstrings W has a length of the pull-out section 1 穿1 passing through the drawstring locator 133, a section passing through the blades (3), one of the guide sheaves 132 and the lower rail 12 The wearing section 1〇2, and a section of the fixed section 1〇3 which is worn by the lower rail 2 and fixed at the bottom end. In use, the drawstring positioning 133 133 is made to adjust the vertical length of the drawstrings 1 to have an appropriate tension. When the user pushes or pulls down the lower rail 2, the lower rail 12 can be maintained at any position by the friction between the wearing straps 1〇2 and the lower rails. In addition to the function of arbitrarily positioning the vertical length, the aforementioned Maoyue patent has the effect of using 3 M430939 since the fixed section 103 of the pull cord 1 is fixed and cannot be played. Although the foregoing invention patent has the above advantages, the vertical elements of the lower rail 12 and the blade 131 are all controlled by the pull cord 1 ,, and since the aforementioned pull cord 1 〇 has no elasticity, when the pull cord 1 is adjusted When the degree of tightness is large, the operator is relatively tight when the lower rail 12 is moved up and down, and the operation is not smooth, and when the tension of the cords is relaxed by the cord locator 133, the operation is performed. Although the lower rail 12 is relatively smooth, the lower rail 12 and the vane 131 are likely to fall suddenly when placed vertically. Further, when the user adjusts the tightness of the drawstrings 10, the positional effect of the drawstring positioner (1) needs to be temporarily released. At this time, the lower rail 12 is also liable to suddenly fall down, resulting in unsafe use. [New content] The purpose of the novel is to provide a safety curtain with better safety for use. The safety curtain of the present invention comprises: an upper rail, a lower rail spaced apart from the upper rail, a blind soap element for lowering the lower rail to be mounted below the upper rail, and a lower rail Flexible cushioning mechanism. The shade unit includes a plurality of blades between the upper rail and the lower rail, a pull positioner mounted on the upper rail, and two through the blades and the lower rail and are pulled by the puller The rope is positioned at the length of the drawstring, and the cushioning mechanism includes a strip buffer cord, and an elastic stringer mounted on the upper rail and imparting a lifting force to the buffer cord, the buffer cord having a mounting The vertical end on the lower rail, and one can be retracted at the elastic end.耵卷 M430939 The beneficial effect of the present invention is that by adding the buffer mechanism between the upper rail and the lower rail, the lower rail can be prevented from falling down, and thus the safety of the safety curtain is improved. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 2' 3, 4, the preferred embodiment of the present invention comprises: an upper rail 21 adapted to be mounted at the upper edge of the window, and an upper and lower spacing of the upper rail 2 22 22, a The lower rail 22 is attached to the shade unit 3' below the upper handle 2! in a liftable manner, and a buffer mechanism 4 for imparting cushioning elasticity to the lower handle 22.
本實施例之上軌21包括兩片前後間隔之翼壁211，以 及-片垂直連接該等翼壁211的上軌基壁212，在該等翼壁 211及4上轨基壁212之間界定出—長條形的容置空間213 。本實施例之下軌22為一中空的管體’並具有一第一軌壁 220平行之第一軌壁221，以及一個連接該第一軌壁 220及該第二軌壁221的圍繞壁222，該第一軌壁221具有 兩個第-穿孔223,而該圍繞壁222具有兩個位在相反側的 第二穿孔224。 本實施例之遮簾單元3包括數個平行位於該上軌21及 該下執22之間的葉片31、_個安裝在該上軌21上的拉繩 定位器32、兩個左右間隔地安裝在該上軌21之上軌基壁 212上的導繩輪33，以及兩條拉繩34。該等拉繩34都具有 5 M430939 丰又穿過刖述葉片31並繞經其中一個導繩輪33及該下軌 22的穿β又段341 ' 一段穿出於該下轨22並固定在例如牆壁 上的固疋段342 ’以及一段穿出於該拉繩定位器32的拉权 •k 343，上述穿設段341在該下軌22内纏繞並垂直彎折， 使該下軌22可以卡靠在該等拉繩34之間。 本實施例之緩衝機構4是位在該等拉繩34之間，並包 括一條緩衝繩41，以及一個安裝在該上軌21之容置空間 213内並賦予δ亥緩衝繩41彈升力的彈性收繩器，該彈性 收繩器42具有-個收繩盒42()，此收繩盒㈣具有一盒壁 421，以及兩支由該盒壁421平行突出的導桿422,而該彈 性收繩器42還具有一個可轉動地安裝該等導桿422的其中 之-上的彈片捲收輪423、-個可轉動地安裝在該等導桿 422之另一個上的收繩輪424，以及一個捲收在該彈片捲收 輪423及收繩輪424上的彈性捲片425。 在本實施例，該收繩輪424及該彈片捲收輪423相嚙 合，且該收繩輪424具有一個供所述彈性捲片425之一固 定端426安裝的彈片捲收部427，以及_個供該緩衝繩w 之一捲收端411捲收的繩捲收部428，而該彈性捲月425是 具彈性地捲收在該彈#捲收輪423上，其固定端似並插 裝在該收繩輪424的彈片捲收部427上。 本實施例之安全窗簾在组裝時，是根據該遮簾單元3 的垂放重量來選擇具有適當捲收力的彈性捲片425,並利用 該拉繩疋位器32來調整該等拉繩34的緊度，調整後藉由 前述拉繩定位器32來定位該等拉繩34之穿設段341的長 6 M430939 度。當該安全窗簾位在圖3的一全展開位置時，由於該缓 衝織41之一垂放端412是安裝在該下軌上故該缓衝 繩41會因為該下軌22的下移而垂放在最大的長度，此時 該收鐵輪424也會受到緩衝繩41的拉動而旋轉，並將彈性 捲片425的大部分往該收絕輪424捲收，同時蓄積回轉的 作用力。當該下軌22被往上推動時，藉由該等拉繩34與 該下軌22之間的阻溫力，以及該緩衝繩41的拉動，可以 讓該下軌22制社移進行捲收，#該下執22被往下拉 動時的作動原理類似，不再說明。 當本實施例在調整該等拉繩34之緊度，而突然解除該 拉繩定位器32的定位功能時’雖然該下軌22及該尊葉片 31本身具有重量可以自動下墜，但由於在該等拉織μ之間 還安裝該緩衝繩4卜且該彈性收繩器42賦予該緩衝繩41 彈性捲收力，因此，即使該等拉繩定位器32突然解除定位 功能，該下軌22還是會緩緩的下降，並可避免下移的下軌 22打傷操作者。相同道理，假設本實施例之安全窗簾的拉 繩34 f度較鬆，而操控者操作該下軌22下移時，即使該 等拉繩34的阻溫力突纽變，也*會造該遮簾單元3及_^ 軌22突訂墜，故本新㈣安全窗簾的設計不僅構造新賴 ’亦具有較佳的使用安全性。 惟以上所述者，僅為本新型之較佳實施例而已，當不 能以此限定本新型實施之範圍，即大凡依本新型申請專利 範圍及新型說明内容所作之簡單的等效變化與修飾皆仍 屬本新型專利涵蓋之範圍内。 7 M430939 【圖式簡單說明】 圖1是US6802356 B2發明專利之一前視示意圖； 圖2是本新型安全窗簾之一較佳實施例的立體示意圖 9 圖3是該較佳實施例之一前視示意圖；及 圖4是該較佳實施例之一未完整的立體分解圖，單獨 顯示該安全窗簾之一緩衝機構。 M430939 【主要元件符號說明】 2 安全窗簾 21 上軌 211翼壁 212上軌基壁 213容置空間 22 下軌 220第一轨壁 221第二轨壁 222圍繞壁 223第一穿孔 224第二穿孔 3 遮簾單元 31 葉片 32 拉繩定位器 33 導繩輪 34 拉繩 341穿設段 342固定段 343拉執段 4 緩衝機構 41 緩衝繩 411捲收端 412垂放端 42 彈性收繩器 420收繩盒 421盒壁 422導桿 423彈片捲收輪 424收繩輪 425彈性捲片 426固定端 427彈片捲收部 428繩捲收部 9The upper rail 21 of the present embodiment includes two front and rear spaced wing walls 211, and an upper rail base wall 212 perpendicularly connecting the wing walls 211, defined between the wing walls 211 and 4 upper rail base walls 212. Out-long strip-shaped accommodation space 213. The lower rail 22 of the present embodiment is a hollow tubular body ′ and has a first rail wall 221 in which the first rail wall 220 is parallel, and a surrounding wall 222 connecting the first rail wall 220 and the second rail wall 221 . The first rail wall 221 has two first through holes 223, and the surrounding wall 222 has two second through holes 224 on opposite sides. The shade unit 3 of the present embodiment includes a plurality of blades 31 located in parallel between the upper rail 21 and the lower handle 22, and a pull cord locator 32 mounted on the upper rail 21, and two left and right spacers are mounted. A sheave 33 on the rail base wall 212 above the upper rail 21, and two drawstrings 34. The drawstrings 34 each have a 5 M430939 abundance and pass through the vane 31 and around one of the sheaves 33 and the lower section 22 of the lower rail 22 through a section of the lower rail 22 and are fixed, for example, The fixed section 342 ′ on the wall and a pulling extension k 343 passing through the cord locator 32, the wearing section 341 is wound in the lower rail 22 and bent vertically, so that the lower rail 22 can be stuck. Relying between the drawstrings 34. The cushioning mechanism 4 of the present embodiment is located between the drawstrings 34 and includes a buffer cord 41, and a spring that is mounted in the accommodating space 213 of the upper rail 21 and imparts a lifting force to the 亥海缓冲绳41. a rope collecting device, the elastic rope collecting device 42 has a collecting box 42 (), the collecting box (4) has a box wall 421, and two guiding rods 422 protruding in parallel from the box wall 421, and the elastic receiving The stringer 42 further has a shrapnel retracting wheel 423 on which the guide rods 422 are rotatably mounted, a take-up reel 424 rotatably mounted on the other of the guide rods 422, and An elastic web 425 is taken up on the shrapnel retracting wheel 423 and the collecting reel 424. In this embodiment, the take-up reel 424 and the shrapnel retracting wheel 423 are engaged, and the take-up reel 424 has a shrapnel retracting portion 427 for mounting the fixed end 426 of the elastic winding piece 425, and The rope winding portion 428 is wound up by the winding end 411 of the buffer cord w, and the elastic waist 425 is elastically wound around the elastic reel 423, and the fixed end is similar to the cartridge It is on the elastic piece winding portion 427 of the rope collecting pulley 424. When the safety curtain of the embodiment is assembled, the elastic winding piece 425 having an appropriate retracting force is selected according to the vertical weight of the blind unit 3, and the pulling cord clamp 32 is used to adjust the pulling rope. The tightness of 34, after adjustment, is positioned by the aforementioned cord locator 32 to length 6 M430939 degrees of the wearing section 341 of the cords 34. When the safety curtain is in a fully deployed position of FIG. 3, since one of the cushioning ends 41 is mounted on the lower rail, the buffer cord 41 may be lowered due to the downward movement of the lower rail 22. When the maximum length is reached, the iron collecting wheel 424 is also rotated by the pulling of the cushioning rope 41, and most of the elastic winding piece 425 is taken up by the collecting wheel 424, and the force of the turning is accumulated. When the lower rail 22 is pushed upward, the lower rail 22 can be moved and retracted by the temperature resistance between the pull cord 34 and the lower rail 22 and the pulling of the buffer cord 41. , # The operation principle of the lower 22 when it is pulled down is similar, no longer explained. When the present embodiment adjusts the tightness of the drawstrings 34 and suddenly releases the positioning function of the drawstring locator 32, although the lower rail 22 and the slatted blade 31 itself have a weight, they can automatically fall, but The cushioning rope 4 is also installed between the woven fabrics, and the elastic rope collecting device 42 imparts an elastic retracting force to the cushioning rope 41. Therefore, even if the cord locators 32 suddenly release the positioning function, the lower rail 22 is still Will slowly fall, and can avoid the lower rail 22 moving down to hurt the operator. By the same token, it is assumed that the pull cord 34 of the safety curtain of the present embodiment is relatively loose, and when the controller operates the lower rail 22 to move down, even if the temperature resistance of the drawstring 34 changes, The blind unit 3 and the _^ rail 22 protrude from the pendant, so the design of the new (four) safety curtain not only has a new structure but also has better safety in use. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the novel patent application scope and the new description content are It is still within the scope of this new patent. 7 M430939 [Simplified illustration of the drawings] Figure 1 is a front view of one of the US6802356 B2 inventions; Figure 2 is a perspective view of a preferred embodiment of the present invention; Figure 3 is a front view of the preferred embodiment FIG. 4 is an incomplete perspective exploded view of one of the preferred embodiments, showing a buffer mechanism of the safety curtain separately.
