Description
本創作與防墜器有關；特別是指一種具有緩衝功能的防墜器。This creation is related to the fall arrester; in particular, a fall arrester with a cushioning function.
一般在屋頂、工廠、電梯維修、造船、航太基地、建築工地等高空作業場所中，多半會籲請人員在作業時，配備防墜器（止墜器）等***品，該防墜器係供連接有一安全帶搭配使用，而該安全帶的一端係繫在工作人員的身上，藉此，當工作人員不慎從高空墜落時，其防墜器可對該安全帶作緊急鎖止或緩衝的動作，藉以防止人員繼續墜落或用來緩衝人員的墜落速度，進而確保工作人員的人身安全。Generally, in high-altitude work sites such as roofs, factories, elevator repairs, shipbuilding, aerospace bases, and construction sites, most people are urged to equip their work with safety parts such as fall arresters (fall arresters). The seat belt is connected with a seat belt, and one end of the seat belt is attached to the worker's body, so that when the worker accidentally falls from a high altitude, the fall arrester can urgently lock or cushion the seat belt. Actions to prevent personnel from continuing to fall or to buffer the speed of the person's fall, thus ensuring the personal safety of the staff.
目前市面可見的防墜器主要有以下幾種態樣，舉例來說，有一種設計係在防墜器之安全帶的結構上作可彈性拉伸的設計，藉此，當繫有安全帶之人員墜落時，其可彈性拉伸的安全帶可用來緩衝、減緩人員的墜落速度。然而，這樣的設計須考慮到安全帶的長度、彈性拉伸係數、所配合之高空作業的高度以及人員體重等因素，且假使作業高度與安全帶的理想作用長度配合不佳時，很有可能的是，安全帶回彈不及而人員卻已墜落至地面，而有所缺失。At present, the anti-dropping devices visible in the market mainly have the following aspects. For example, one design is designed to be elastically stretchable on the structure of the safety belt of the fall arrester, thereby being equipped with a seat belt. When the person falls, the elastically stretchable seat belt can be used to cushion and slow the falling speed of the person. However, such a design must take into account factors such as the length of the seat belt, the elastic stretch factor, the height of the aerial work to be matched, and the weight of the person, and it is highly probable that if the working height does not match the ideal length of the seat belt. The safety belt has rebounded and the personnel have fallen to the ground and are missing.
另外，有一種防墜器的設計在於，其安全帶的其中一段係作交疊地縫合，藉此，當人員墜落時，其安全帶交疊縫合的部位將因受力而被扯開，藉以吸收人員部分的墜落能量，來達到緩衝的效果。惟這樣的設計對安全帶會產生結構上的破壞，以至於安全帶的強度、承載力下降，而有危險之虞。In addition, there is a fall arrester designed such that one of the belts of the seat belt is stitched in an overlapping manner, whereby when the person falls, the portion of the seat belt overlapped and stitched is torn apart by the force, thereby Absorb the energy of the part of the person to achieve the cushioning effect. However, such a design would cause structural damage to the seat belt, so that the strength and bearing capacity of the seat belt are reduced, and there is danger.
除此之外，另有一種防墜器係採取快速鎖止的方式，亦即，當人員墜落而產生瞬間的拉力時，防墜器將緊急鎖止其安全帶以使安全帶不續落，其中，這樣的設計雖然可達到立即阻止人員墜落的效果，然而在其緊急停止的瞬間所產生的瞬間衝擊力（如G-Force）與反作用力，將可能導致人員得內傷甚至是有骨骼斷裂的意外情況發生，而有尚待改進之處。In addition, a fall arrester adopts a quick lock mode, that is, when a person falls and generates an instantaneous pulling force, the fall arrester will urgently lock the seat belt so that the seat belt does not continue to fall. Among them, although such a design can achieve the effect of immediately preventing the person from falling, the instantaneous impact force (such as G-Force) and reaction force generated at the moment of emergency stop may cause internal injuries or even bone fracture. Unexpected circumstances occur and there are areas for improvement.
有鑑於此，本創作之目的在於提供一種具緩衝功能的防墜器，可緩衝使用者的下墜速度。In view of this, the purpose of this creation is to provide a cushioning function of the fall arrester, which can cushion the user's falling speed.

本創作之效果在於，當繫有該安全帶的人員墜落時，該安全帶的一端所承受之拉力將大於一預定值，進而拉動該架體，使連接於該架體上的該緩衝件克服與該緩衝柱之間的最大靜摩擦力，使得該緩衝件與該緩衝柱之間產生摩擦滑動，而該緩衝件與緩衝柱之間所產生的滑動摩擦力可供緩衝、吸收人員的下墜衝力，並降低人員下墜的速度、降低對人員的傷害，以及降低回彈而造成二次傷害的機會。The effect of the present invention is that when a person wearing the seat belt falls, the tension of one end of the seat belt is greater than a predetermined value, thereby pulling the frame body to overcome the cushioning member attached to the frame body. The maximum static friction between the buffer column and the buffer column causes frictional sliding between the buffer member and the buffer column, and the sliding friction force generated between the buffer member and the buffer column can buffer and absorb the falling force of the person. It also reduces the speed at which people fall, reduces the damage to personnel, and reduces the chance of secondary damage caused by rebound.

In particular, the outer casing 70 includes a first half-shell 72 and a second half-shell 74. The first half-shell 72 is provided with a first partition 73, and the second half-shell 74 is disposed. A second partition 75 is opposite the first partition 73. The first half shell 72 and the second half shell 74 can be combined by a positioning member such as a bolt S, and when the first half shell 72 is docked with the second half shell 74, the first partition plate 73 and the first half shell 72 The second partition plate 75 is opposite to each other, and the accommodating space of the outer casing 70 is divided into two parts, so that the frame body 10 and the rotating member 20 are located on one side of the first partition plate 73 and the second partition plate 75. In the accommodating space, the braking device 50 is located in the accommodating space on the other side of the first partition plate 73 and the second partition plate 75. Therefore, the rotating member 20 is separated from the braking device 50 through the design of the first partition plate 73 and the second partition plate 75, so as to reduce and avoid the intrusion of foreign matter such as dust which may be caused by the safety belt 26 around which the rotating member 20 is wound. Or attached to the brake device 50, affecting the chance of the brake device 50 being actuated. Further, since the scroll spring 66 is housed in the first lid body 62 and the second lid body 64, it also has a function of preventing foreign matter such as dust from entering. Further, the cushioning device 30 is also provided with the effect of blocking the adhesion of foreign matter such as dust by the rotor 20 and the seat belt 26 by the isolation effect of the top plate 12. In addition, in an embodiment, the outer casing 70 may not cover the buffer device 30, so that the buffer device 30 is exposed outside the outer casing, and is not limited to the above description.
藉此，透過上述設計，於一般使用情境下，例如人員正常地在如一工作平台、棧板上行走時，該轉動件20、制動裝置50以及回捲裝置60同軸轉動（或稱同步轉動），且當安全帶26被拉伸且所承受的拉力小於一預定值時，例如：連接有安全帶200的工作人員遠離該防墜器100而使得安全帶200被拉伸時，該回捲裝置60的渦捲彈簧66將隨著安全帶200被拉伸而拉伸，而可隨之蓄積有一捲收成卷的回復力（或稱彈力）；另外，當工作人員接近防墜器100時，拉伸安全帶26的力將減弱而小於渦捲彈簧66的彈力，此時，渦捲彈簧66便會產生彈性回復而收納成捲，進而帶動安全帶26一併再度捲繞收回轉鼓24上。Thereby, through the above design, in a general use situation, for example, when a person normally walks on a working platform or a pallet, the rotating member 20, the braking device 50, and the rewinding device 60 rotate coaxially (or synchronously rotate), And when the seat belt 26 is stretched and the tensile force is less than a predetermined value, for example, when the worker connected to the seat belt 200 is away from the fall arrester 100 and the seat belt 200 is stretched, the rewinding device 60 The scroll spring 66 will be stretched as the seat belt 200 is stretched, and a recovery force (or elastic force) of a roll of the roll may be accumulated therewith; in addition, when the worker approaches the fall arrester 100, the stretch The force of the seat belt 26 will be weaker than the spring force of the scroll spring 66. At this time, the scroll spring 66 will elastically recover and be stored in a roll, and the belt 26 will be driven again and retracted onto the drum 24.
另外，於另一使用情境下，當安全帶26被瞬間快速拉伸時，例如：連接有安全帶26的工作人員不慎自高空墜落時，安全帶26將被急遽拉伸，且安全帶26所受的拉力將大於一預定值，而使得制動裝置50的制動塊54克服復位彈簧56的彈力而向外甩出，進而該制動塊54將卡掣於一設置於架體10的擋止件15上，而該制動盤52將受制動塊54與擋止件15相卡合的影響而固定不動，而與制動盤52相固接的軸桿22亦固定不動。請一併配合圖２及圖３所示，此時，由於受該制動裝置50卡掣固定的影響以及軸桿22固定不動的影響，該安全帶26所受之拉力將拉動該架體10以及與架體10相連接的支架32向下移動，而該支架32將牽動緩衝環36同步向下移動，使得該緩衝環36的第二摩擦面36a克服與定置於錨定點之緩衝柱34的第一摩擦面34a之間的最大靜摩擦力，而使得該緩衝環36與該緩衝柱34之間產生摩擦滑動而相對位移，進而形成如圖４所示的狀態，其中，該緩衝柱34之第一摩擦面34a與緩衝環36之第二摩擦面36a之間所產生的滑動摩擦力，將可供緩衝該安全帶26以及連接有該安全帶26之工作人員下降之作用力（或稱衝力），進而達到緩衝、吸收人員的下墜衝力，並降低人員下墜的速度，以及降低對工作人員之傷害的目的，除此之外，還可避免安全帶26的回彈，進而降低因安全帶26回彈而造成人員二次傷害的情況發生。In addition, in another use scenario, when the seat belt 26 is rapidly stretched in an instant, for example, when a worker attached to the seat belt 26 accidentally falls from a high altitude, the seat belt 26 will be rapidly stretched, and the seat belt 26 The tension received will be greater than a predetermined value, so that the brake block 54 of the brake device 50 is pulled outward against the elastic force of the return spring 56, and the brake block 54 will be clamped to a stop member disposed on the frame 10. 15 , the brake disc 52 is fixed by the engagement of the brake block 54 and the stopper 15 , and the shaft 22 fixed to the brake disc 52 is also fixed. Please refer to FIG. 2 and FIG. 3 together. At this time, due to the influence of the locking and fixing of the braking device 50 and the fixing of the shaft 22, the pulling force of the seat belt 26 will pull the frame 10 and The bracket 32 coupled to the frame 10 is moved downward, and the bracket 32 moves the pull-up buffer ring 36 downwardly so that the second friction surface 36a of the buffer ring 36 overcomes the first portion of the buffer column 34 disposed at the anchor point. The maximum static friction between the friction surfaces 34a causes the frictional sliding between the buffer ring 36 and the buffer column 34 to be relatively displaced, thereby forming a state as shown in FIG. 4, wherein the first of the buffer columns 34 The sliding friction generated between the friction surface 34a and the second friction surface 36a of the buffer ring 36 will serve to cushion the seat belt 26 and the force (or impulse) of the worker connected to the seat belt 26, In addition, it can buffer and absorb the falling force of the person, reduce the speed of the person falling, and reduce the damage to the staff. In addition, the rebound of the seat belt 26 can be avoided, thereby reducing the rebound of the seat belt 26 Causing people Case of a second injury occurs.
值得一提的是，請配合圖３及圖４所示，於本實施例中，在緩衝柱34與緩衝環36之間還可設置有彈簧38，而透過該彈簧38頂抵於緩衝柱34及緩衝環36之間的彈力，可與緩衝柱34和緩衝環36之間的滑動摩擦力配合，可更進一步提升緩衝、抵銷安全帶26和人員下降衝力的效果。例如，當安全帶26下墜而拉動轉動件20和架體10時，將帶動緩衝環36與緩衝柱34產生滑動之相對位移，以及壓縮於其間的彈簧38，從而壓縮該彈簧38的反向彈力便可緩衝該安全帶26的下墜衝力。另外，於一情況下，當下降衝力被消除後，該彈簧38的回復彈力亦可用來幫助緩衝柱34與緩衝環36回復至如圖３所示的初始狀態。此外，值得說明的是，於其他應用上，並不以設置有該彈簧38為限，於一實施例中，亦可不設置有彈簧38，而單靠緩衝柱34與緩衝環36之間摩擦滑動所產生的滑動摩擦力作為緩衝安全帶26下墜的衝力。It should be noted that, as shown in FIG. 3 and FIG. 4 , in the embodiment, a spring 38 may be disposed between the buffer column 34 and the buffer ring 36 , and the spring 38 is pressed against the buffer column 34 . The elastic force between the buffer ring 36 and the sliding friction between the buffer column 34 and the buffer ring 36 can further enhance the effect of cushioning, offsetting the safety belt 26 and the downward force of the person. For example, when the seat belt 26 is lowered to pull the rotating member 20 and the frame body 10, the relative displacement of the buffer ring 36 and the buffer column 34 is generated, and the spring 38 compressed therebetween is compressed, thereby compressing the reverse elastic force of the spring 38. The falling force of the seat belt 26 can be buffered. In addition, in one case, when the downward momentum is eliminated, the return spring force of the spring 38 can also be used to help the buffer column 34 and the buffer ring 36 return to the initial state as shown in FIG. In addition, it should be noted that, in other applications, the spring 38 is not provided. In an embodiment, the spring 38 may not be disposed, and the buffer column 34 and the buffer ring 36 may be frictionally slid. The resulting sliding friction acts as a force to cushion the seat belt 26 from falling.
此外，於一實施例中，所述的彈簧也可以是一拉伸彈簧，該拉伸彈簧連接於該架體10以及該緩衝柱34之間，用以提供該緩衝柱34回復至常態位置的彈力，而不以上述的壓縮彈簧為限。除此之外，於其他應用上，亦可使用其他種類的彈簧，而不以上述說明為限。In addition, in an embodiment, the spring may also be a tension spring connected between the frame body 10 and the buffer column 34 to provide the buffer column 34 to return to the normal position. Elasticity, not limited to the compression spring described above. In addition, other types of springs may be used for other applications, and are not limited to the above description.
另外，請參圖５所示，為本創作另一實施例的防墜器200，與前述實施例之防墜器100的不同之處在於：該防墜器200之緩衝裝置包括有一緩衝件80以及一緩衝柱90，該緩衝件80設置於該架體10上，且該緩衝件80具有一穿孔，該穿孔的孔壁構成第二摩擦面80a；該緩衝柱90設置於該架體10以及該緩衝件80之間，且該緩衝柱90的一端自該穿孔穿出，且該緩衝柱90的外周面構成第一摩擦面90a，與該第二摩擦面80a相配合，藉此，同樣可藉由緩衝件80與緩衝柱90之間的摩擦滑動來達到緩衝安全帶以及工作人員下墜的衝力以及下墜速度的效果。另外，於該緩衝裝置中同樣可設置有一彈簧92與緩衝柱90相連接，以提供緩衝柱90適當的彈力，例如，於本實施例中，該彈簧92為一壓縮攤簧，套設於該緩衝柱90上，且一端抵於緩衝柱90，另一端抵於緩衝件80上，而可額外提供良好的緩衝效果。此外，於一實施例中，所述的彈簧92亦可為其他種類的彈簧，例如為一拉伸彈簧，該拉伸彈簧連接於該緩衝柱90以及架體10之間，而不以上述說明為限。In addition, referring to FIG. 5, the fall arrester 200 of another embodiment of the present invention is different from the fall arrester 100 of the foregoing embodiment in that the buffer device of the fall arrester 200 includes a buffer member 80. And a buffering member 90 disposed on the frame body 10, and the buffering member 80 has a through hole, the perforated hole wall forming a second friction surface 80a; the buffer column 90 is disposed on the frame body 10 and Between the buffer members 80, one end of the buffer column 90 is pierced from the through hole, and the outer peripheral surface of the buffer column 90 constitutes a first friction surface 90a, and cooperates with the second friction surface 80a. The frictional sliding between the cushioning member 80 and the buffer column 90 achieves the effect of cushioning the seat belt and the force of the worker to fall and the speed of the falling. In addition, a spring 92 may be disposed in the buffer device to be coupled to the buffer column 90 to provide a suitable elastic force of the buffer column 90. For example, in the embodiment, the spring 92 is a compression spring, and is disposed on the buffer spring 90. The buffer column 90 has one end that abuts the buffer column 90 and the other end abuts against the buffer member 80, and additionally provides a good buffering effect. In addition, in an embodiment, the spring 92 may be another kind of spring, such as a tension spring, and the tension spring is connected between the buffer column 90 and the frame body 10, instead of the above description. Limited.
值得一提的是，前述安全帶所承受之拉力是否大於一預定值，其中所述之預定值是作為判斷是否啟動緩衝裝置之緩衝效果的參考之用，於實務的不同應用上，所述的預定值可能根據防墜器的不同配值而為不同的數值，例如，所述預定值的大小主要為緩衝柱與緩衝件之間的摩擦力，以及若緩衝裝置還設有彈簧時，則該預定值的大小還需考慮該彈簧所提供的彈力。另外，於一實施例中，並不以設置有制動裝置或回捲裝置為限，舉例而言，當轉動件上所捲繞之安全帶被拉出直到轉動件停止轉動，例如安全帶被拉到底或接近到底時，該安全帶施於該轉動件的作用力將會大於一預定值，而拉動該緩衝裝置的緩衝件，使得緩衝件與緩衝柱之間產生摩擦滑動，進而可緩衝所產生之下墜衝力。It is worth mentioning whether the tensile force received by the aforementioned safety belt is greater than a predetermined value, wherein the predetermined value is used as a reference for judging whether to activate the buffering effect of the buffering device, and in different applications of the practice, the The predetermined value may be different according to different values of the fall arrester. For example, the predetermined value is mainly the friction between the buffer column and the buffer member, and if the buffer device is further provided with a spring, the The size of the predetermined value also needs to consider the spring force provided by the spring. In addition, in an embodiment, it is not limited to the provision of the braking device or the rewinding device. For example, when the safety belt wound on the rotating member is pulled out until the rotating member stops rotating, for example, the seat belt is pulled. In the end or near to the end, the force applied by the seat belt to the rotating member will be greater than a predetermined value, and the cushioning member of the cushioning device is pulled to cause frictional sliding between the cushioning member and the buffer column, thereby being buffered. Under the impact.
以上所述僅為本創作較佳可行實施例而已，本創作之防墜器不僅可供繫在工作人員的身上，藉以在工作人員墜落時提供防墜的效果，亦可繫在施工材料、機具等的物體上，而同樣可達到防止急速下墜的效果，舉凡應用本創作說明書及申請專利範圍所為之等效變化，理應包含在本創作之專利範圍內。The above description is only a preferred and feasible embodiment of the present invention. The fall arrester of the present invention can be used not only to be attached to the staff member, but also to provide a fall prevention effect when the worker falls, or to be attached to construction materials and implements. For the same object, the same effect can be achieved to prevent the rapid fall. The equivalent change of the application specification and the scope of the patent application should be included in the scope of the patent.
