Description

一种帐篷
本申请要求2021年5月17日提交的申请号为CN 2021210535342的中国专利申请的优先权。
技术领域
本发明属于帐篷领域，具体涉及一种帐篷。
背景技术
帐篷在日常生活中十分常见，普遍用于户外。传统的帐篷遮阳面积较小，为了增大帐篷展开后的遮阳面积，设计出了带屋檐结构的屋檐式帐篷。具体为在帐篷的顶角处设有伸出的挑檐杆，通过设在挑檐杆上的围边达到增大遮阳面积的目的。现有的屋檐式帐篷，其挑檐杆通常随着帐篷架的展开而伸出，在帐篷展开后无法再对挑檐杆进行调节，例如不能将挑檐杆缩回或者调节其伸出的长度，使用不够灵活。
发明内容
为解决上述技术问题，本发明旨在提供一种帐篷，能够在帐篷展开后根据使用需求调节挑檐杆，使用较为灵活。

顶架2为可折叠的顶架，且设置在至少三个立柱3上。参照图1至图2所示，本实施例中的顶架2具体包括至少四个外顶杆组件和一个中心锁5，四个外顶杆组件的内端部通过枢轴可转动地连接于中心锁5上，从而使得四个外顶杆102构成分别沿帐篷顶架2的对角线向帐篷的四个顶角延伸的十字形结构，且彼此可以相对转动。每个外顶杆组件分别包括外顶杆102和内顶杆，外顶杆102的外端部可转动地连接于立柱3的上端部，外顶杆102的内端部和内顶杆的外端部相转动连接，内顶杆的内端部可转动地连接于中心锁5。帐篷架1还包括多个侧杆组件4，侧杆组件4由一或多个依次相转动连接的十字撑杆件41构成，每个十字撑杆件41分别包括分别具有上端和下端的第一连杆42和第二连杆43，第一连杆42的中部和第二连杆43的中部通过枢轴相转动连接而交叉构成十字形结构。具体到本实施例中，每个侧杆组件4由三个十字撑杆件41构成，其中，第一连杆42的上端与一个立柱3的上端部或另一个十字撑杆件41的第二连杆43的上端相转动连接，第一连杆42的下端与另一个十字撑杆件41的第二连杆的下端或另一个立柱3上的另一个滑块104相转动连接，第二连杆43的下端与一个立柱3上的滑块104或另一个十字撑杆件41的第一连杆43的下端相转动连接，第二连杆43的上端与另一个十字撑杆件41的第一连杆42的上端或另一个立柱3的上端部相转动连接。
本实施例中的挑檐杆101为扁管，其为至少部分中空的管状。挑檐杆101可沿其长度方向滑动地设置于外顶杆102上，挑檐杆101位于外顶杆102的旁侧。帐篷架1在展开状态时挑檐杆101具有缩回位置(如图3所示)和至少一个伸出位置。具体到本实施例中，挑檐杆101的伸出位置仅一个，具体为图4所示的位置。
参照图3至图6所示，帐篷还包括锁定装置6，锁定装置6具有能够至少在帐篷架1处于展开状态时将挑檐杆101锁定在伸出位置的锁定状态及将挑檐杆101释放的解锁状态。锁定装置6包括锁件107，锁件107设置于挑檐杆101上。具体到本实施例中，锁件为定位弹片，其具有弹性。锁件101具有能够与外顶杆102可脱离地接合的锁定部113，锁定部113具体包括凸起114，挑檐杆或顶架2的外顶杆102上设有可供 凸起114插入的锁孔115。凸起114插设于锁孔115中时锁定装置6处于锁定状态，凸起114脱离锁孔115时锁定装置6处于解锁状态。
参照图5和图6所示，顶架2的外顶杆102上设置有挑檐接头106，挑檐接头106通过挑檐接头拉钉108固定于外顶杆102上。挑檐杆101可滑动地连接于挑檐接头106，锁件107设置在挑檐杆101的管腔内，挑檐杆101的管壁上开设有通孔116，凸起114位于通孔116中，锁孔115设于挑檐接头106上。锁件107具有弹性且其中部折弯而具有相对的两端部，凸起114设于其中一个端部上，另一个端部抵在挑檐杆101的内壁的与通孔116相对的部位上。
如图6所示，顶架2上设有滑动座109，滑动座109通过滑动座拉钉110固定于外顶杆102上，挑檐杆101可滑动地连接于滑动座109，滑动座109具有上表面，上表面设有两个凹槽用于容置挑檐杆101和外顶杆102，且挑檐杆101相对于外顶杆102滑动。
顶架2上还设有连结座111，连结座111通过铆钉112固定于顶架2上，连结座111具有上表面，上表面设有凹槽，用于容置外顶杆102，且连结座111与外顶杆102可滑动地连接。连结座111具有下表面。斜杆103自连结座111的下表面伸入并与连结座111可转动地以铆钉连接。
结合图3和图6所示，立柱3的上端部设有上顶节105，用于连接立柱3与顶架2。每个立柱3上设有一个滑块104，滑块104可滑动地设置于立柱3上，斜杆103可转动地连接于滑块104。当帐篷架1在折叠状态时，挑檐杆101处于其缩回位置，且挑檐杆101的顶端低于立柱3的顶端，具体为立柱3上端的上顶节105。帐篷架在展开状态、折叠状态、展开过程中及折叠过程中，挑檐杆101的长度方向均平行或大致平行于外顶杆102的长度方向。
参照图1、图2及图6，当帐篷架1处于展开状态时，挑檐杆101向外拉伸至展开位置时，挑檐杆101上的通孔116和外顶杆102上的锁孔115相互对齐，锁件107的弹性复位力驱动凸起114向外运动而插设于锁孔115中，锁定装置6处于锁定状态而将挑檐杆101锁定在该伸出位置下。需要将挑檐杆101缩回时，按下凸起114，锁件107被挤压变形，凸起114退出锁孔115而退回至挑檐杆101内，锁定解除，挑檐杆101可相对外顶杆102滑动，进而可将挑檐杆101缩回。
本实施例中，挑檐杆101在其伸出位置和缩回位置之间的切换独立于帐篷架1的展开或折叠，可视具体需求(如需要屋檐或不需要屋檐)，而相应将挑檐杆101伸出或缩回，尤其是能够在帐篷展开后灵活选择将挑檐杆101伸出或缩回，且帐篷折叠后挑檐杆101可缩回，不额外占用空间。同时，挑檐杆101可被锁定在其伸出位置，能够稳定地保持在伸出位置。
实施例2:参照图8至图15所示，本实施例与实施例1的区别在于：锁定装置6的结构不同，且挑檐杆201采用轻便的实心玻纤杆，外径远小于实施例1所用的扁管。其他基本同实施例1。
本实施例中，如图12至图14所示，锁定装置6包括锁件202，锁件202具体为具有弹性的弹片，且其折弯而具有第一端部204和第二端部205，第一端部204抵在挑檐杆201的外表面上，第二端部205上开设有锁孔115。顶架2的外顶杆102上设置有挑檐接头106，挑檐接头106通过挑檐接头拉钉108固定于外顶杆102上。锁件107设置在挑檐杆201内，挑檐杆201可滑动地穿设在挑檐接头106中并自锁件107的锁孔115中穿过，挑檐接头106还具有可供手指伸入以拨动锁件107的空间。
锁孔115的截面面积大于挑檐杆201的截面面积。锁孔115的中心线和挑檐杆201的长度方向之间的夹角大于一临界值且挑檐杆201抵在锁孔115的孔壁上时，锁定装置6处于锁定状态；夹角小于或等于临界值而使挑檐杆201能够在锁孔115中滑动时，锁定装置6处于解锁状态。该临界值可以为5度，2度，甚至 可以为零，也就是说，当挑檐杆201的长度方向和锁孔115的中心线相互平行甚至重合时，挑檐杆201能够在锁孔115中移动；当锁孔115的中心线一旦偏离挑檐杆201的长度方向，挑檐杆201抵在锁孔115的相对两侧孔壁上而被锁定，不能够相对外顶杆102滑动。“锁孔115的截面”具体是指锁孔115在锁件202的第二端部205所处的平面内的截面，“锁孔115的中心线”垂直于锁件202的第二端部205所处的平面；“挑檐杆201的截面”具体是指挑檐杆201的垂直于其长度方向的截面。
如图13所示，挑檐杆201的的两端部还设有限位套203，限位套203套设于挑檐杆201的两端部上，限位套203的截面面积至少大于锁孔115的截面面积，以在挑檐杆201切换工作状态将挑檐杆201的工作行程限制于顶架2上而不至于脱落。
当帐篷架1处于展开状态时，按压锁件202的第二端部使其转动一定角度，直至其上的锁孔115的中心线和挑檐杆201的长度方向的夹角小于或等于临界值，挑檐杆201和锁孔115能够相对滑动，将挑檐杆201向外拉伸至任一位置(均视为伸出位置)，将锁件释放，锁件复位，锁孔115的中心线偏离挑檐杆201的长度方向的角度大于上述临界值，挑檐杆201抵在锁孔115的相对两侧孔壁上，从而被锁定。
本实施例中，挑檐杆201在其伸出位置和缩回位置之间的切换独立于帐篷架1的展开或折叠，可视具体需求(如是否需要屋檐、屋檐的大小)，而相应将挑檐杆201伸出或缩回，尤其是能够在帐篷展开后灵活选择将挑檐杆201伸出至任意长度或缩回，能够无极调节，且帐篷折叠后挑檐杆201可缩回，不额外占用空间。同时，挑檐杆201可被锁定在其任意位置，能够稳定地保持在伸出位置或缩回位置。
实施例3:参照图16至图19所示，本实施例与实施例2的区别仅在于：锁件的形状。其他基本同实施例2。
本实施例中，挑檐杆201采用实心的玻纤杆，外径远小于实施例1所用的扁管。锁件301整体呈U形，其中部折弯而具有相对的第一端部和第二端部，第一端部和第二端部上分别开设有锁孔115。锁件301设置在挑檐杆201内，挑檐杆201可滑动地穿设挑檐接头106中并自锁件107的两个锁孔115中穿过，挑檐接头106还具有可供手指伸入以拨动锁件107的空间。
两个锁孔115的截面面积大于挑檐杆201的截面面积，优选地，两个锁孔115的截面面积相等。各锁孔115的中心线和挑檐杆201的长度方向之间的夹角大于一临界值且挑檐杆201抵在锁孔115的孔壁上时，锁定装置6处于锁定状态。夹角小于或等于临界值而使挑檐杆201能够在锁孔115中滑动时，锁定装置6处于解锁状态。该临界值可以为5度，2度，甚至可以为零，也就是说，当挑檐杆201的长度方向和两个锁孔115的中心线相互平行甚至重合时，挑檐杆201能够在锁孔115中移动。其中一个锁孔115的中心线一旦偏离挑檐杆201的长度方向，挑檐杆201抵在该锁孔115的相对两侧孔壁上而被锁定，不能够相对外顶杆102滑动。两个锁孔115偏离挑檐杆201的方向相反。“锁孔115的截面”具体是指锁孔115在锁件301的第一端部或第二端部所处的平面内的截面，“锁孔115的中心线”垂直于锁件301的第一端部或第二端部所处的平面。
如图18所示，挑檐杆201的的两端部还设有限位套203，限位套203套设于挑檐杆201的两端部上，限位套203的截面面积至少大于锁孔115的截面面积，以在挑檐杆201切换工作状态将挑檐杆201的工作行程限制于顶架2上而不至于脱落。
当帐篷架1处于展开状态时，按压锁件301使其第一端部和第二端部相互靠近，直至其上的两个锁孔115的中心线和挑檐杆201的长度方向的夹角均小于或等于临界值，挑檐杆201和锁孔115能够相对滑动，将挑檐杆201向外拉伸至任一位置(均视为伸出位置)，将锁件301释放，锁件301复位，其第一端部和 第二端部而向外张开，锁孔115的中心线偏离挑檐杆201的长度方向的角度大于上述临界值，挑檐杆201抵在锁孔115的相对两侧孔壁上，从而被锁定。
本实施例中，挑檐杆201在其伸出位置和缩回位置之间的切换独立于帐篷架1的展开或折叠，可视具体需求(如是否需要屋檐、屋檐的大小)，而相应将挑檐杆201伸出或缩回，尤其是能够在帐篷展开后灵活选择将挑檐杆201伸出至任意长度或缩回，能够无极调节，且帐篷折叠后挑檐杆201可缩回，不额外占用空间。同时，挑檐杆201可被锁定在其任意位置，锁定更为牢固，能够稳定地保持在伸出位置或缩回位置。
实施例4:参照图20至图26所示，本实施例与实施例2的区别在于：解锁装置6。其他基本同实施例2。
本实施例中，挑檐杆201为实心的玻纤杆，外径远小于实施例1所用的扁管。参照图24至图26所示，锁件107包括一个锁片或多个层叠设置的锁片401。具体地，每个锁片401上分别设有一个锁孔115。锁片401均活动地设置于外顶杆102上的挑檐接头106内，挑檐杆201可沿其长度方向滑动地穿设在挑檐接头106中并自各锁片401的锁孔115中穿过。锁片401具有位于锁孔115的相对两侧的内端部403和外端部404，挑檐接头106具有位于锁片401的旁侧(如图中所示的右侧)的限位部405，锁片401的内端部403的一侧表面(如图中的右侧表面)抵在限位部405上。锁定装置6还包括用于使锁片401的外端部404朝向限位部405所处的一侧(即右侧)偏置的弹性件402。弹性件402具体为设于锁片401左侧的弹簧，弹性件402具有供挑檐杆201穿过的通孔，弹性件402和限位部405分别位于锁片401的左右两侧，弹性件402的左端抵在挑檐接头106的内壁上而右端抵在锁片401的外端部404上。
两个锁孔115的截面面积大于挑檐杆201的截面面积，优选地，两个锁孔115的截面面积相等。各锁孔115的中心线和挑檐杆201的长度方向之间的夹角大于一临界值且挑檐杆201抵在锁孔115的孔壁上时，锁定装置6处于锁定状态。夹角小于或等于临界值而使挑檐杆201能够在锁孔115中滑动时，锁定装置6处于解锁状态。该临界值可以为5度，2度，甚至可以为零，也就是说，当挑檐杆201的长度方向和两个锁孔115的中心线相互平行甚至重合时，挑檐杆201能够在锁孔115中移动。其中一个锁孔115的中心线一旦偏离挑檐杆201的长度方向，挑檐杆201抵在该锁孔115的相对两侧孔壁上而被锁定，不能够相对外顶杆102滑动。“锁孔115的截面”具体是指锁孔115在锁片401所处的平面内的截面，“锁孔115的中心线”垂直于锁片401所处的平面。
当帐篷架1处于展开状态时，向左拨动锁片401的外端部，直至其上的锁孔115的中心线和挑檐杆201的长度方向的夹角均小于或等于临界值，挑檐杆201和锁孔115能够相对滑动，将挑檐杆201向外拉伸至任一位置(均视为伸出位置)，将锁片401释放，锁片401的外端部在弹性件402的弹性复位力的作用下向右偏置，锁孔115的中心线偏离挑檐杆201的长度方向的角度大于上述临界值，挑檐杆201抵在锁孔115的相对两侧孔壁上，从而被锁定。
本实施例中，挑檐杆201在其伸出位置和缩回位置之间的切换独立于帐篷架1的展开或折叠，可视具体需求(如是否需要屋檐、屋檐的大小)，而相应将挑檐杆201伸出或缩回，尤其是能够在帐篷展开后灵活选择将挑檐杆201伸出至任意长度或缩回，能够无极调节，且帐篷折叠后挑檐杆201可缩回，不额外占用空间。同时，挑檐杆201可被锁定在其任意位置，锁定更为牢固，能够稳定地保持在伸出位置或缩回位置。
上述实施例只为说明本发明的技术构思及特点，是一种优选的实施例，其目的在于熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限定本发明的保护范围。
