Description

升降坐具 技术领域
本发明涉及一种坐具，尤其涉及升降坐具。
背景技术
升降椅主要由椅座、底座、升降定位装置和椅脚构成。由于升降椅的椅座可进行升降因此可以适应不同身高的人进行坐姿或站姿。但是升降椅结构较为复杂，外观上不够简洁美观。
墩椅是目前所流行的椅子种类，其具有外观简洁美观的优点，被广大民众所青睐。但是目前市场上的墩椅不具有升降功能，因此不同身材的人需要不同的墩椅，其适用性相对较低。
针对目前市场上的升降椅和墩椅的缺陷，申请人设计了一种新型的升降坐具，使得其具有墩椅简洁美观外形的同时具备升降的功能。
 技术解决方案
为了解决上述问题，本发明的目的在于提供一种外观简洁美观，同时具有升降功能的升降坐具。
为了实现上述的目的，本发明采用了以下的技术方案：
升降坐具，包括基座组件、升降组件以及座部组件，所述升降组件下端安装在基座组件内，升降组件的上端与座部组件连接，还包括环绕升降坐具侧面一周设置的弹性遮蔽罩，所述的弹性遮蔽罩上下两端分别与座部组件、基座组件接合，且弹性遮蔽罩在升降组件作用下随座部组件升降而伸缩。
通过在座部组件和基座组件之间设置升降组件，并且设置弹性遮蔽罩并使得其上下两端分别与座部组件和基座组件相接合，以使得基座组件和升降组件被罩设在弹性遮蔽罩内，外观简洁美观，同时由于弹性遮蔽罩在升降组件作用下随座部组件升降而伸缩，使得椅子同时具备了升降功能。
作为优选，所述弹性遮蔽罩由弹性橡胶、弹性塑料、弹性纤维、弹性织物中的一种或多种制成。
作为优选，所述的弹性遮蔽罩包括筒形本体及设置在筒形本体下端的连接件，筒形本体通过连接件与基座组件接合。
作为优选，所述筒形本体由弹性橡胶、弹性塑料、弹性纤维、弹性织物中的一种或多种制成。
作为优选，所述筒形本体上端缝制在座部组件的侧面。
作为优选，所述筒形本体罩设在座部组件并整体向下延伸。
作为优选，所述基座组件下端的外缘设置有多个倒扣，所述连接件与基座组件装配完成后，在筒形本体的弹性回复力作用下，连接件与倒扣抵接。这种连接方式，充分利用了弹性织物本身特性，其结构简单、安装快捷，有效限定了连接件在轴向上的运动。
作为优选，所述倒扣下端设置有第一卡齿，所述连接件设置有第二卡齿，连接件安装到基座组件上后第一卡齿和第二卡齿啮合。通过第一卡齿和第二卡齿的啮合，有效限定了连接件在周向上的运动，使得连接件与基座组件保持静止或同步转动。
作为优选，所述倒扣包括扣接部，所述扣接部沿基座组件的外侧斜向下设置，该扣接部为弹性件，可向内挤压。
在安装过程中，连接件与扣接部外侧的斜面相抵，不断将扣接部向内挤压，当连接件安装到位时，扣接部弹出回复原位，此时，扣接部上的第一卡齿和连接件上的第二卡齿啮合。
作为优选，所述连接件包括外侧由上至下呈逐渐向内凹陷的圆弧形的持握部、内侧竖直或倾斜设置的支撑部以及设置在支撑部上端的卡齿部，所述持握部与支撑部之间具有一定空间。
持握部的这种形状是为了在安装过程中便于手的持握，持握部与支撑部之间具有一定空间是因为在调高升降坐具的过程中，弹性面料会对持握部的上端施加一个向内的分立，该空间可以提供持握部向内形变的一个空间。其中支撑部的材料可以采用不具弹性不可压缩形变的材料，采用这种材料制成的支撑部，在连接件安装完，扣接部弹出回复原位后，由于支撑部不可形变，因此不可拆卸，连接件的使用寿命很长；支撑部的材料也可以使用具有弹性、可以压缩变形的材料，采用这种材料制成的支撑部，在连接件安装完，扣接部弹出回复原位后，由于支撑部可形变，因而连接件可以拆卸，但是由于在拆卸过程中会对连接件造成破坏，长久积累下来可能导致连接件松弛，不能与扣接部配合的情形发生。
作为优选，所述基座组件包括下底座和可绕下底座转动的上底座。
作为优选，所述上底座和下底座之间设置有转动机构，该转动机构包括基座盘以及与该基座盘轴接的转动盘，所述连接件固定在上底座上。通过设置转动机构，使得座部组件及弹性遮蔽罩可以360度转动。
作为优选，所述转动盘为方盘。
作为优选，所述基座组件包括下底座和上底座，在上底座的中心处设置有安装腔，在安装腔内设置有锥套组件，升降组件的下端固定在锥套组件内。
作为优选，所述锥套组件包括第一气杆锥套以及包裹在第一气杆锥套外侧的弹性套，所述弹性套与安装腔过盈配合，升降组件的下端固定在第一气杆锥套内。
通过设置弹性套，使得人体在调整坐姿过程中，升降组件受到一个弹性的回复力，且由于弹性套可压缩变形，使得升降坐具具备了调节人体坐姿的功能。
作为优选，所述第一气杆锥套的外侧一体成型地设置有固定环，该固定环嵌入弹性套内。
作为优选，所述弹性套为一整体。
作为优选，所述弹性套有两块，固定环位于两块弹性套之间。
作为优选，所述弹性套开设有多个竖直方向的蜂孔。通过设置竖直方向的蜂孔，使得升降组件在前后左右调整过程中，弹性套具有足够的压缩空间，使得调节的范围大大变宽。
作为优选，所述升降组件包括升降气杆、L型控制板和拉带，所述拉带一端与L型控制板连接，拉带另一端穿过筒形本体露于升降坐具外侧。
作为优选，所述座部组件包括底盘，所述底盘中心处设置有第二气杆锥套，升降组件的上端过盈插接在第二气杆锥套内。
 有益效果
1.通过在座部组件和基座组件之间设置升降组件，并且设置弹性遮蔽罩并使得其上下两端分别与座部组件和基座组件相接合，以使得基座组件和升降组件被罩设在弹性遮蔽罩内，外观简洁美观，同时由于弹性遮蔽罩在升降组件作用下随座部组件升降而伸缩，使得椅子同时具备了升降功能。
2.通过设置转动机构，使得座部组件及弹性遮蔽罩可以360度转动。
3.通过设置弹性套，使得人体在调整坐姿过程中，升降组件受到一个弹性的回复力，且由于弹性套可压缩变形，使得升降坐具具备了调节人体坐姿的功能。

以下结合附图对本专利作进一步说明。
实施例1：
如图1～图2所示的升降坐具，包括基座组件100、升降组件200、座部组件300以及弹性遮蔽罩400。其中，升降组件200下端安装在基座组件100内，升降组件200的上端与座部组件300连接，弹性遮蔽罩400环绕升降坐具侧面一周设置，且弹性遮蔽罩400在升降组件200作用下随座部组件300升降而伸缩。通过在座部组件300和基座组件100之间设置升降组件200，并且设置弹性遮蔽罩400并使得其上下两端分别与座部组件300和基座组件100相接合，以使得基座组件100和升降组件200被罩设在弹性遮蔽罩400内，外观简洁美观，同时由于弹性遮蔽罩400在升降组件200作用下随座部组件300升降而伸缩，使得椅子同时具备了升降功能。
如图2、图7所示，弹性遮蔽罩400包括由弹性织物构成的筒形本体410及设置在筒形本体410下端的连接件420，筒形本体410的下端通过连接件420与基座组件100接合，筒形本体410的上端可以缝制在座部组件300的侧面，或者在筒形本体410上端设置布罩，通过布罩罩设在座部组件300上，并整体向下延伸。连接件420包括外侧由上至下呈逐渐向内凹陷的圆弧形的持握部422、内侧竖直或倾斜设置的支撑部423以及设置在支撑部423上端的卡齿部424，卡齿部424上设有第二卡齿421，在持握部422与支撑部423之间具有一定空间。持握部422的这种形状是为了在安装过程中便于手的持握，持握部422与支撑部423之间具有一定空间是因为在调高升降坐具的过程中，弹性面料会对持握部422的上端施加一个向内的分立，该空间可以提供持握部422向内形变的一个空间。
如图2～图6所示，在基座组件100下端的外缘设置有多个倒扣121，倒扣的数量优选6个。倒扣121包括扣接部123，扣接部123沿基座组件100的外侧斜向下设置，该扣接部123为弹性件，可向内挤压，在扣接部123的下端设置有第一卡齿122。在基座组件100上还设置有容置槽124，用于在扣接部123向内挤压时容纳扣接部123。
弹性遮蔽罩400与基座组件100的装配过程如下：安装人手握住持握部422并将之向下拉，在此过程中，连接件420与扣接部123外侧的斜面相抵，不断将扣接部123向内挤压，当连接件420安装到位后，扣接部123弹出回复原位，此时，在弹性织物制成的筒形本体410的弹性回复力作用下，扣接部123上的第一卡齿122和连接件420上的第二卡齿421牢固啮合，使得连接件420在周向上的运动被有效限定，使得连接件420与基座组件100保持静止或同步转动，充分利用了弹性织物本身特性。
支撑部423的材料采用不具弹性不可压缩形变的材料。采用这种材料制成的支撑部423，在连接件420安装完，扣接部123弹出回复原位后，由于支撑部423不可形变，因此不可拆卸，连接件420的使用寿命很长。
如图4～图6所示，基座组件100包括下底座110和可绕下底座110转动的上底座120。为了减小摩擦，在下底座的下端设置有五个呈脚钉111，五个脚钉111呈正五边形分布。作为优选方式，在上底座120和下底座110之间设置有转动机构130，该转动机构130包括基座盘131以及与该基座盘131轴接的转动盘132，倒扣121设置在在上底座120的下部外缘上。为了节约材料，转动盘132设置为方盘。通过设置转动机构130，使得座部组件300及弹性遮蔽罩400可以360度转动。
在上底座120的中心处设置有安装腔125，在安装腔125内设置有锥套组件600。锥套组件600包括第一气杆锥套610以及包裹在第一气杆锥套610外侧的弹性套620，该弹性套620与安装腔125过盈配合。在第一气杆锥套610外侧还套设有橡胶压板630，橡胶压板630紧贴弹性套620上端面设置。在第一气杆锥套610的外侧一体成型地设置有固定环611，第一气杆锥套610与弹性套620装配好后，该固定环611嵌入弹性套620内。在弹性套620上开设有多个竖直方向的蜂孔621。通过设置弹性套620，使得人体在调整坐姿过程中，升降组件200受到一个弹性的回复力，且由于弹性套620可压缩变形，使得升降坐具具备了调节人体坐姿的功能。通过设置竖直方向的蜂孔621，使得升降组件200在前后左右调整过程中，弹性套620具有足够的压缩空间，使得调节的范围大大变宽。弹性套620可以为一整体也可以由两块构成。当弹性套620有两块构成时，固定环611装配与两块弹性套620之间。
如图2、图7所示，座部组件300包括底盘310以及设置在底盘上的软性坐垫320。底盘310包括底板311以及设置在底板311下端面中心处的第二气杆锥套312。第二气杆锥套312呈漏斗形，其下端为漏斗嘴。
如图2所示，升降组件200包括升降气杆210、L型控制板220和拉带230，拉带230一端与L型控制板220连接，拉带230另一端穿过筒形本体410露于升降坐具外侧。L型控制板220的一端与拉带230连接，L型控制板220的一端另一端与升降气杆210的开关键相连。升降气杆210的下端过盈插接在第一气杆锥套610内，与第一气杆锥套610内保持相对静止状态，升降气杆210的上端过盈插接在第二气杆锥套312的漏斗嘴处，与第二气杆锥套312内保持相对静止状态。当需要调节升降坐具高度时，拉动拉带230，带动L型控制板220与升降气杆210的开关键接触，此时，升降气杆210调节高度。通过向上提座部组件300或者向下压座部组件300，可以实现高度调节的目的，在放松拉带230后，高度固定。
实施例2：
本实施例与实施例1的区别技术特征在于：连接件420（包括支撑部423）的材料使用具有弹性、可以压缩变形的材料。采用这种材料制成的支撑部423，在连接件420安装完，扣接部123弹出回复原位后，由于支撑部423可形变，因而连接件420可以拆卸，但是由于在拆卸过程中会对连接件420造成破坏，长久积累下来可能导致连接件420松弛，不能与扣接部123配合的情形发生。
实施例3：
本实施例与实施例2的区别技术在于：扣接部123沿基座组件100的外侧竖直向下设置，且扣接部123的材料可以是弹性可压缩材料，也可以是非弹性不可压缩材料。
弹性遮蔽罩400与基座组件100的装配过程如下：安装人手握住持握部422并将之向下拉，当下拉到位后，将连接件420向外拉伸，使得其下端可以通过扣接部123，当连接件420下拉倒扣接部123之下后，松开将连接件420拉开的力，此时连接件回复原装，松开施加在连接件向下的力后，在弹性织物制成的筒形本体410的弹性回复力作用下，扣接部123上的第一卡齿122和连接件420上的第二卡齿421牢固啮合。
实施例4：
本实施例与实施例3的区别技术特征在于：连接件420为弹性圆环，扣接部123下端没有设置第一卡齿122。
上述实施例仅为本专利较佳的实施方式，其中实施例1为效果最佳的实施例。上述实施例并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
