Description

遮蔽物结构 技术领域
本发明涉及遮蔽物结构，如伞，特别涉及大型无需支撑物的伞。
背景技术
本发明涉及遮蔽物结构，如伞，特别是大型无需支撑物的伞。这样的伞通常通过将滑块在伞杆上下推动而展开并折叠。伞肋的长度通常取决于伞盖的大小。如果伞盖很大，伞肋会很长。这导致了大型伞不能在类似花园家具的物体旁边折叠或展开的不想要的情况，因为伞肋会与这些物品相撞。此外，这样的伞不能放置在桌子的中间，因为台面将会妨碍完全折叠或展开。此外，放置在桌面上的物品可能会在这样一次尝试被扫除。
简单地延伸杆并由此升高连接伞肋的伞的顶部将不能解决问题。这因此将导致滑块在伞的展开位置中的相应更高的位置，使得该伞不能由具有正常或甚至更矮的人处理。
大型无支撑物的伞的另一个问题是，伞盖的较大尺寸自动导致伞肋和/或伞盖的较高重量。伞的展开和折叠因此变得更加困难。
US4424824A公开了一种伞，其具有支撑管最上端部分，其中可伸缩地容纳有承载伞冠的伞轴，其可枢转连接有盖肋，套筒与支撑管成外伸缩关系，多个支杆可枢转地连接在套筒和盖肋之间，伞轴内的螺纹主轴相对于螺纹螺母固定到伞轴，以及具有固定到套筒和伞轴且被引导到由伞轴承载的滑轮上的端部的柔性元件，例如电缆、绳索或电线。结果是，打开和关闭伞盖的过程非常复杂。伞盖关闭，而伞轴伸长，换句话说，关闭或打开伞盖且同时延长或伸缩伞轴，即两个动作是同步的。从支撑管向外延伸的导向管的长度非常长，所以折叠的伞的顶部将会非常高。这是不利的，例如，当存放伞特别是在屋顶等处时。当用于运输而折叠时现有的伞需要更多的空间，其等于导致更高的运输成本。此外，为了便于打开和关闭过程，现有的伞的整体操作系统包括螺纹装置，以螺纹轴的形式的螺纹装置，其以不可取代或固定的方式通过斜齿轮形式的齿轮装置支撑在下端部分。这使得现有的伞的制造复杂、耗时且昂贵。
US8087420B1公开了一种用于促进伞的折叠和展开的更简单的系统，该系统公开了一种伞系统，其包括配重和滑轮系统，其中滑轮系统包括配置有配重的类1和类2滑轮以在伞的正常操作中获得机械优势。然而，这种现有技术未教导任何解决方案，甚至未讨论大伞盖的长伞肋的问题。
发明内容
本发明要解决的基本技术问题为提供一种可在其他物体附近操作或在桌子中部操作的伞，即使伞盖较大且伞肋较长。折叠的伞的高度应相对较低。伞的机构要简单易行且成本低廉。伞应容易打开和关闭。
根据本发明的伞解决该技术问题。上毂固定于导向管上，而不是像传统的伞那样固定于支撑管上。导向管可伸缩地设置在支撑管的最上端部分中并相对于支撑管的最上端部分可相互移动。导向管和滑块、套筒或转轮(runner)通过以柔性牵引构件的形式的柔性牵引装置互相连接在一起，例如绳子。优选地，牵引构件可以由固定到支撑管的上端部的滑轮形式的滑轮装置引导。柔性牵引构件的一端牢固地固定在滑块上，另一端牢固地固定在配重部件上。有利的是，如果柔性牵引构件，例如绳索，穿过支撑管中的配重部件，而柔性牵引构件的两端牢固地固定在滑块上。优选地，配重的重量以这样的方式确定，即配重支撑滑块的向上运动，从而有利于伞的打开。
根据本发明的遮蔽物结构的操作通过第二实施例更加方便。为了节省一些力量，增加了一个自由滑轮系统。该滑轮系统由附加的推杆组成，该推杆可伸缩地设置在支撑管和导向管中，并且其通过附加的牵引构件操作，例如绳索，其由安装在导向管和支撑管上的附加滑轮引导。当折叠伞时，配重部件致动推杆，推杆向上推动导向管。用于实施本发明的实施例在附图中示出，并且如下详细描述。
附图说明
图1示出了根据本发明的伞处于展开状态的优选实施例。
图2为图1中的该伞的细节1。
图3为图1中的该伞的细节2。
图4示出了根据本发明处于其关闭位置的伞。
图5示出了图4的细节。
图6示出了本发明的第二实施例.
图7示出了在打开/关闭过程中的细节。
图8示出了根据本发明的第二实施例处于关闭状态的伞。
具体实施方式
图1示出了根据本发明的伞处于展开状态的优选实施例。图2和图3显示了该伞的细节。伞具有肋9a，其一端可枢转地连接到上毂1。支杆9b支撑肋9a，且一端可枢转地连接到肋9a，并在另一端处连接到滑块3。滑块3可以朝向支撑管5上下移动。上毂1固定在导向管4的上端。导向管4的直径小于支撑管5的直径，使得导向管4可以在支撑管5内移动。由此，导向管4可伸缩地设置在支撑管5的最上端部分8中且相对于支撑管5的最上端部分8可相互移动。滑块3可以通过常规方式保持在其最高位置，例如，通过至少一个或多个可枢转地安装钩10，其在支撑管5中突出对应的开口。至少一个柔性牵引构件6的至少一端，例如绳索，固定在滑块3上。在支撑管5的上端部分8处设有引导牵引构件6的至少一个滑轮2。该柔性牵引构件6的另一端可以固定到配重7，其位于支撑管5内并在支撑管5内可移动。图1示出了本发明的优选实施例，其中单个牵引构件6的两端连接到滑块3，并且柔性牵引构件6由安装在支撑管5的上端部分8上的两个滑轮2的装置引导。在该优选实施例中，配重部件7具有滑轮2'，牵引部件6被引导到该滑轮上。因此，可以减小配重部件7倾斜的可能危险。
当关闭伞时，滑块3朝向支撑管5下方移动。由此，滑块3拉动柔性牵引构件6，使得连接到柔性牵引构件6的配重构件7向上提升。当配重部件7的上端与导向管4的下端相接触时，导向管4被配重部件7向上推动。由此，与导向管4连接的上毂1被提升。在这同时引起可枢转地连接到上毂1的肋8的提升。
图4示出了根据本发明处于其关闭位置的伞，并且图5示出了其中的细节。可以容易地看出，上毂1和相应的肋9a以在关闭过程中大大降低在伞的下面或附近的物体与伞特别是肋9a接触的危险的方式被提升。
应根据伞盖和其肋9a以及支杆9b的尺寸大小和重量来选择配重部件7的重量。通常可以以一种方式来确定配重部件的重量大小，即该配重可以自动地向上拉起互相连接的滑块。如果是这样，可能有利于在支撑管5中设置额外的开口，滑块3的钩10可能在伞关闭的位置中侵入到其中，以便将滑块固定在该位置中。
图6示出了本发明的第二实施例，并且图7示出了在打开/关闭过程中的细节。增加了一个自由滑轮系统来节省一些力量。绳索6的路径与第一实施例中相同。推杆11可伸缩地设置在支撑管5和导向管4中。有三个滑轮12、13和13'。滑轮12安装在滑轮架14上的推杆11上，并且滑轮13和13'安装在滑轮架14上的导向管4上。第二牵引构件的一端，例如绳15，牢固地固定到支撑管5上。通过由滑轮架14支撑的滑轮12和由滑轮架14支撑的滑轮13及 13'的绳索15的另一端也牢固地固定到支撑管5上。即，由滑轮架14支撑的滑轮12为自由滑轮。因此，当用户直接或间接地向下拉动滑块3时，绳索6将会拉动配重部件7向上移动。配重部件7将会接触并推动推杆11向上。导向管4由推杆11提升，然后伞盖将会缓慢关闭。
图8示出了根据本发明的第二实施例处于关闭状态的伞。
在此说明书中，本发明已参照其特定的实施例作了描述。但是，很显然仍可以作出各种修改和变换而不背离本发明的精神和范围。因此，说明书和附图应被认为是说明性的而非限制性的。
