Description

说明书方便折叠的自动开收伞技术领域 Description Automatic folding umbrella for easy folding

本发明涉及一种曰常使用的伞具，特别是涉及一种自动开收的多折伞。背景技术 The invention relates to an umbrella used frequently, and in particular to a multi-fold umbrella which is automatically opened. Background technique

现有技术中，有一种自动开收的多折伞，它通过在中棒内腔设置开伞弹簧提供伸展中棒的动力，在伞骨上设置拉簧等结构提供伞骨收折的动力，一个可被固定在伞头内或被释放的子弹头以及两端分别与该子弹头和下巢连接的拉线可以拉动下巢上滑开伞或者释放下巢收伞。如公告号为 CN2827075 的中国发明专利就公开了一种多折伞的自动开、收装置，通过按压伞头上的按钮就能实现开伞或收折伞骨的目的。但是现有的这种自动开收伞在收伞时只能是折叠伞骨，并不能折叠中棒，还需要使用者用力将中棒展开的各节管体压缩到位才能完全收伞，但因为中棒各节管体都伸展开来比较长，要完全压缩起来需要较大的力气才能完成，所以对于年老体弱者就感觉非常不方便。发明内容 In the prior art, there is a multi-folding umbrella which is automatically opened and closed, which provides power for stretching the rod by providing an open umbrella spring in the inner cavity of the middle rod, and a structure such as a tension spring is arranged on the rib to provide power for folding the rib. A bullet that can be fixed in the umbrella head or released and a wire that is respectively connected to the bullet and the lower nest at both ends can pull the lower nest to open the umbrella or release the nest. For example, the Chinese invention patent with the publication number CN2827075 discloses an automatic opening and closing device for a multi-fold umbrella, and the purpose of opening or folding the rib can be achieved by pressing a button on the umbrella head. However, the existing automatic opening and closing umbrella can only fold the rib during the umbrella collection, and cannot fold the middle rod. It also requires the user to force the tube sections of the middle rod to be compressed into position to completely close the umbrella, but because The tubes in the middle of the stick are stretched out for a long time. To be fully compressed, it takes a lot of effort to complete, so it is very inconvenient for the elderly and the weak. Summary of the invention

A latch 751 is provided in the umbrella head 3 in conjunction with the button 75, and a spring 752 urges the buckle 751 toward the middle rod 1. The end of the card member 77 is pushed inward by the return spring 78, thereby maintaining the tendency to snap the bullet 71 into the umbrella head 3. The above structures are all prior art, and are not described herein again.

下面分别以三折伞和四折伞为例对本发明的改进之处作详细说明。 The improvement of the present invention will be described in detail below by taking a three-fold umbrella and a four-fold umbrella as examples.

当为三折伞时，如图 2和图 3所示，所述中棒 2包括从内至外依次滑动套接的内管 21、第一外管 22和第二外管 23。本发明的特别之处在于：还包括设置在所述中棒 2内的拉簧 6和第二拉线 81。该拉簧 6的两端分别固定于所述第一外管 22和第二外管 23的顶部，由此使第一外管 22和第二外管 23保持收缩折叠的趋势。所述第一外管 22顶部固定有第一顶塞 91，该第一顶塞 91上开设有可供所述第一拉线 72穿过的通孔 93 , 且该第一顶塞 91上还安装有第一滑轮 27。所述第二拉线 81 —端固定在所述子弹头 71上，另一端绕经该第一滑轮 27 后与所述第二外管 23的底部连接。所述开伞弹簧 73安装在内管 21和第一外管 22内，保持一个将该第一外管 22和内管 21伸展开来的趋势。 When it is a three-fold umbrella, as shown in FIG. 2 and FIG. 3, the middle rod 2 includes an inner tube 21, a first outer tube 22, and a second outer tube 23 which are sequentially slidably sleeved from the inside to the outside. The special features of the present invention are: A tension spring 6 and a second wire 81 are disposed in the middle bar 2. Both ends of the tension spring 6 are fixed to the tops of the first outer tube 22 and the second outer tube 23, respectively, thereby keeping the first outer tube 22 and the second outer tube 23 in a tendency to shrink and fold. A first plug 91 is fixed on the top of the first outer tube 22. The first plug 91 is provided with a through hole 93 through which the first cable 72 passes, and the first plug 91 is mounted thereon. There is a first pulley 27. The second pull wire 81 is fixed at the end to the bullet 71, and the other end is connected to the bottom of the second outer tube 23 after passing through the first pulley 27. The open spring 73 is mounted in the inner tube 21 and the first outer tube 22, maintaining a tendency to extend the first outer tube 22 and the inner tube 21.

如图 2 , 所述第二外管 23的底部外固定套接有第一外管套 25，该第一外管套 25在与第二外管 23相接处设有一通孔，所述第二拉线 81的其中一端穿过该通孔并打结由此卡接于该第一外管套 25上。此结构能将第二拉线 81可靠地连接在第二外管 23的底部，且第一外管套 25的内壁阻挡在该第二拉线 81端部与第一外管 22之间，能防止第二拉线 81的端部打结处与第一外管 22摩擦而损坏。 As shown in FIG. 2, the first outer sleeve 25 is sleeved with a first outer sleeve 25, and the first outer sleeve 25 is provided with a through hole at a position adjacent to the second outer tube 23. One end of the second pull wire 81 passes through the through hole and is knotted thereby being engaged with the first outer sleeve 25 . This structure can reliably connect the second pull wire 81 to the bottom of the second outer tube 23, and the inner wall of the first outer sleeve 25 is blocked between the end of the second pull wire 81 and the first outer tube 22, thereby preventing the first The end knot of the second pull wire 81 is damaged by friction with the first outer tube 22.

所述第一拉线 72和第二拉线 81与子弹头 71连接的方法有多种，如图 7所示，可在子弹头 71内开两个孔 711 , 第一拉线 72和第二拉线 81分别穿过该两个孔 711后在该两孔的底部打结固定。或者，如图 8所示，在子弹头 71内腔中设一内塞 712，该内塞 712上开有两个孔分别供第一拉线 72和第二拉线 81穿过并打结固定。又或者，如图 9所示，在子弹头 71内腔中设一内塞 712 , 该内塞 712上开有两个孔分别供第一拉线 72和第二拉线 81穿过，并在内塞 712下方设一圆轴 713,所述第一拉线 72和第二拉线 81的底端呈圈状并套在该圆轴 713上固定。 There are a plurality of methods for connecting the first pull wire 72 and the second pull wire 81 to the bullet 71. As shown in FIG. 7, two holes 711 can be opened in the bullet 71, and the first pull wire 72 and the second pull wire 81 respectively After passing through the two holes 711, they are knotted and fixed at the bottom of the two holes. Alternatively, as shown in Fig. 8, an inner plug 712 is disposed in the inner cavity of the bullet 71. The inner plug 712 has two holes formed therein for the first pull wire 72 and the second pull wire 81 to pass through and be knotted and fixed. Or, as shown in FIG. 9, an inner plug 712 is disposed in the inner cavity of the bullet 71, and the inner plug 712 has two holes for the first pull wire 72 and the second pull wire 81 to pass through, respectively. A round shaft 713 is disposed under the 712, and the bottom ends of the first pull wire 72 and the second pull wire 81 are looped and sleeved on the round shaft 713.

当第一次按压按钮 75使伞处于完全打开状态时，如图 3所示，此时第二外管 23被释放，滑套 76失去第二外管 23的压制力后在复位弹簧 79的作用下上升至与按钮 75对应的位置，但子弹头 71仍然被卡制件 77锁定在伞头 3内，在开伞弹簧 73的伸展力作用下，所述第一外管 ₂₂向上弹升，使得子弹头 71与第一滑轮 27之间的距离变长，所述第二拉线 81便将第二外管 23的底部向上拉升至开伞的最高位，此时，第一拉线 72通过上巢 51滑轮 54和下巢 52滑轮 55将该下巢 51向上拉至最高位，使得伞骨总成 1完全张开，同时拉簧 6被拉长。当第二次按压按钮 75收伞时，如图 4所示，按钮 75通过滑套 76按动卡制件 77上端，使得该卡制件 77的下端抵抗复位弹簧 78的弹力而外移从而释放子弹头 71 , 该子弹头 71便会向上弹升至中棒 2 内腔中，此时，下巢 51失去第一拉线 72 的拉力，伞骨总成 1便会在收伞骨弹簧 11 的作用下自动收折起来，并推动下巢 52下移。同时，第二外管 23也失去了第二拉线 81的拉力，在拉簧 6 的拉力作用下，第二外管 23就会向下折叠于第一外管 22 外面，此时，中棒 1 需压缩的长度只有内管 21 和第一外管 22 两折，收伞所需的力量就大大减小，使用起来更加方便。 When the button 75 is pressed for the first time to bring the umbrella into a fully open state, as shown in FIG. 3, at this time, the second outer tube 23 is released, and the sliding sleeve 76 loses the pressing force of the second outer tube 23 and acts on the return spring 79. The lower portion is raised to the position corresponding to the button 75, but the bullet 71 is still locked in the umbrella head 3 by the engaging member 77. Under the extension force of the open umbrella spring 73, the first outer tube _{22 is} lifted upward, so that the bullet is made. The distance between the head 71 and the first pulley 27 becomes longer, and the second cable 81 pulls the bottom of the second outer tube 23 upward to the highest position of the open umbrella. At this time, the first cable 72 passes through the upper nest 51. The pulley 54 and the lower nest 52 pulley 55 pull the lower nest 51 up to the highest position, so that the rib assembly 1 is fully opened and the tension spring 6 is elongated. When the button 75 is pressed for the second time, as shown in FIG. 4, the button 75 pushes the upper end of the engaging member 77 through the sliding sleeve 76, so that the lower end of the engaging member 77 is moved outward against the elastic force of the return spring 78 to release The bullet 71, the bullet 71 will be lifted up to the inner cavity of the middle rod 2, at this time, the lower nest 51 loses the pulling force of the first pull line 72, and the rib assembly 1 will be under the action of the rib spring 11 Automatically folds up and pushes the lower nest 52 down. At the same time, the second outer tube 23 also loses the pulling force of the second pulling wire 81. Under the pulling force of the tension spring 6, the second outer tube 23 is folded downwardly outside the first outer tube 22, at this time, the middle rod 1 The length to be compressed is only two folds of the inner tube 21 and the first outer tube 22, and the force required for the umbrella is greatly reduced, which is more convenient to use.

当将中棒 2压缩折叠到位时，如图 5所示，弹簧 752推动卡扣 751 内移并卡在第二外管 23的收伞卡口位处从而将第二外管 23锁定，同时滑套 76被第二外管 23向下压。胶管 74则被第一外管 22顶部的第一顶塞 91 向下压由此将子弹头 71压入伞头 3内并被卡制件 77锁定，开伞弹簧 73被压缩，积蓄能量为下次开伞做准备。 When the middle rod 2 is compressed and folded into position, as shown in FIG. 5, the spring 752 pushes the buckle 751 to move inwardly and is caught at the position of the umbrella card slot of the second outer tube 23 to lock the second outer tube 23 while sliding. The sleeve 76 is pressed down by the second outer tube 23. The hose 74 is pressed downward by the first plug 91 at the top of the first outer tube 22, thereby pressing the bullet 71 into the umbrella head 3 and being locked by the locking member 77. The open spring 73 is compressed and the energy is stored. Prepare for the next open umbrella.

当为四折伞时，如图 6 所示，本发明的自动开收伞是在三折伞的基础上增加了：第三外管 24、第三拉线 82和第二滑轮 28。所述第三外管 24套接在第二外管 23外，所述第二外管 23顶部固定设置有第二顶塞 92 , 该第二顶塞 92上也开设有可供所述第一拉线 72 穿过的通孔，所述第二滑轮 28安装在该第二顶塞 92上，所述第三拉线 82—端固定于所述第一外管 22顶部的第一顶塞 91上，另一端绕经该第二滑轮 28后与所述第三外管 24 的底部连接。同样，该第三外管 24的底部外固定套接有第二外管套 26，第三拉线 82连接在该第二外管套 26上。 When it is a four-fold umbrella, as shown in Fig. 6, the automatic opening and closing umbrella of the present invention is added on the basis of a three-fold umbrella: a third outer tube 24, a third pulling line 82, and a second pulley 28. The third outer tube 24 is sleeved on the outside of the second outer tube 23, and the second outer plug 23 is fixedly disposed on the top of the second outer tube 23, and the second top plug 92 is also provided with the first top plug 92. a through hole through which the wire 72 passes, the second pulley 28 is mounted on the second top plug 92, and the third wire 82 is fixed to the first top plug 91 at the top of the first outer tube 22. The other end is connected to the bottom of the third outer tube 24 after passing through the second pulley 28. Similarly, the bottom of the third outer tube 24 is externally sleeved with a second outer sleeve 26, and the third cable 82 is attached to the second outer sleeve 26.

当按压按钮 75开伞时，第二外管 23被释放，但子弹头 71仍然被卡制件 77 锁定在伞头 3内，在开伞弹簧 73的伸展力作用下，所述第一外管 22向上弹升，使得子弹头 71与第一滑轮 27之间的距离变长，所述第二拉线 81便将第二外管 23的底部向上拉升至开伞的最高位，这样，第一顶塞 91与第二滑轮 28之间的距离也相应变长，所述第三外管 24 的底部便被第三拉线 82 向上拉升至开伞的最高位。此时，第一拉线 72通过上巢 51滑轮 54和下巢 52滑轮 55将该下巢 51 向上拉至最高位，使得伞骨总成 1完全张开，同时拉簧 6被拉长。收伞时，与三折伞相同，由于子弹头 71被释放，下巢 52失去第一拉线 72 的拉力而下移，伞骨总成 1 自动收折，同时，第二外管 23也失去了第二拉线 81 的拉力，在拉簧 6 的拉力作用下，第二外管 23就会向下折叠于第一外管 22外面，此时，第一顶塞 91 与第二滑轮 28 之间的距离也相应变短，在伞骨总成 1 自重及下巢 52 下移的推动力作用下，该第三外管 24也会向下折叠于第二外管 23外。可见，该四折伞也只需压缩内管 21和第一外管 22两折管体即可。 When the button 75 is opened, the second outer tube 23 is released, but the bullet 71 is still locked in the umbrella head 3 by the engaging member 77, and the first outer tube is under the action of the extension force of the opening spring 73. 22 is lifted upwards, so that the distance between the bullet 71 and the first pulley 27 becomes longer, and the second pull wire 81 pulls the bottom of the second outer tube 23 upward to the highest position of the open umbrella, so that the first top The distance between the plug 91 and the second pulley 28 is also lengthened accordingly, and the bottom of the third outer tube 24 is pulled up by the third pull wire 82 to the highest position of the open umbrella. At this time, the first pull wire 72 pulls the lower nest 51 up to the highest position by the upper nest 51 pulley 54 and the lower nest 52 pulley 55, so that the rib assembly 1 is fully opened, and the tension spring 6 is elongated. When the umbrella is closed, the same as the three-folded umbrella, since the bullet 71 is released, the lower nest 52 loses the pulling force of the first cable 72 and moves downward, the rib assembly 1 is automatically folded, and the second outer tube 23 is also lost. The pulling force of the second pulling wire 81, under the pulling force of the tension spring 6, the second outer tube 23 is folded downwardly outside the first outer tube 22, at this time, between the first top plug 91 and the second pulley 28 The distance is also shortened correspondingly, and the third outer tube 24 is also folded downwardly outside the second outer tube 23 under the driving force of the rib assembly 1 self-weight and the lower nest 52 moving downward. It can be seen that the four-fold umbrella only needs to compress the inner tube 21 and the first outer tube 22 to fold the tube body.

本发明的自动开收伞还可应用于四折以上的多折伞，只需在相应的外管上增加拉线和滑轮，必要时增加拉簧，同样可以达到收伞时自动折叠部分管体的目的。以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。 The automatic opening and closing umbrella of the invention can also be applied to the multi-folding umbrella of more than 40 folds, only need to add the pulling wire and the pulley on the corresponding outer tube, and if necessary, increase the tension spring, and also can automatically fold part of the pipe body when the umbrella is closed. purpose.
