Description

梯子 技术领域
本发明涉及一种梯子。
 背景技术
梯子作为日常生活、生产用具，在建筑、安装、消防、家庭等领域被广泛应用。梯子由两根位于两侧的杆件做边，中间连接两侧杆件的多根横杆用作攀爬。
梯子根据种类主要可以分为直梯、人字梯、伸缩梯等。直梯是最简单的梯子，仅包括两根杆件及多根横杆；人字梯相当于两组直梯，在使用时呈“人”字状；伸缩梯则可以在高度上进行伸缩，直梯、人字梯均可以做成伸缩梯。直梯结构简单，价格便宜；人字梯使用稳定，比较安全；伸缩梯收缩后，体积小，方便收纳。因此，每种梯子均具有各自的优缺点。
以直梯为例，使用时顶部是与高处的墙壁或者物品接触，底部是与低处的地面接触，由于顶部、底部都是接触式的支撑，因此在使用过程中，很容易出现移动、滑行、甚至是倾倒，造成安全隐患，这也使得在使用直梯时，往往需要有人在底下扶住，确保使用的安全性。

 具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
如图1所示的一种梯子，包括梯子主体1，梯子主体1可以为直梯，也可以为伸缩梯。无论是直梯、还是伸缩梯，梯子主体1均包括位于两侧的侧杆10、连接在两侧的侧杆10之间的横杆11，横杆11设置有多个，多个横杆11沿侧杆10的长度方向分布，形成供攀爬的踩踏杆。
在本申请的一个实施例中：梯子还包括定位结构，该定位结构即为提高其安全性的结构，定位结构连接在梯子主体1的顶部，本申请中的顶部是与高处的支撑物5接触的一端，支撑物5如墙壁或者物品，底部是与低处的地面接触的一端。
定位结构包括定位连接杆20、定位支腿21，定位连接杆20与梯子主体1连接，具体与梯子主体1顶部的横杆11连接，如顶部的第一个横杆、第二个横杆等，但与顶部的第一个横杆连接最优，且定位连接杆20、横杆11均为沿梯子主体1的宽度方向延伸；定位支腿21连接在定位连接杆20上，定位支腿21可以设置一个、两个或者更多，但是两个最优，分别连接在定位连接杆20的两端，可以确定定位的稳定性。
在本实施例中：定位支腿21包括定位连杆210、定位板211，定位连杆210连接在定位连接杆20与定位板211之间，定位板211用于与高处的支撑物5定位，定位可以是支撑、也可以是固定等。
具体的说：定位连杆210包括固定杆210a、一对转动杆210b，固定杆210a的一端与定位连接杆20的一端固定连接，并且固定杆210a与定位连接杆20相垂直，两者的垂直处还可以设置加强块22，提高两者之间的连接强度；一对转动杆210b呈“人”字形，一对转动杆210b的一端与固定杆210a的另一端三者之间通过同一转动连接件23可转动地连接，一对转动杆210b的另一端与定位板211可转动地连接，整个定位连杆210呈“Y”形。当然，一对转动杆210b的一端与固定杆210a的另一端也可以两两转动连接。
定位板211上还连接有垫块24，定位连杆210、垫块24分别连接在定位板211的相对两侧，垫块24可以增加定位板211与支撑物5之间的摩擦力。
定位板211根据支撑物5形状的不同，设置多种形态：
在一种形态下：如图2所示：定位板211为一块直板，然后通过紧固件4（例如螺钉、螺栓和螺母的组合灯）进行定位固定，如图4、图5所示，此时定位板211通过紧固件4固定在平面的支撑物5上。
定位板211可以根据支撑物5形状的不同进行变化。具体的：
如图6、图7所示，此时将定位板211折弯成一定角度，形成折弯板，图示以90°为例，折弯的定位板211与支撑物5的直角面贴合，并通过紧固件4固定在直角面上。当然定位板211折弯的角度可以视支撑物5外表面的形状而定。
如图8、图9所示，此时将定位板211弯曲呈弧形，形成弧形板，弧形的定位板211与支撑物5的弧面贴合，并通过紧固件4固定在弧面上。当然弯曲的弧度可以视支撑物5外表面的形状而定。
在另一种形态下：如图3所示：定位板211包括板主体211a、转动板211b，一对转动杆210b的另一端与板主体211a连接，转动板211b可转动地连接在板主体211a的至少一端，图示以板主体211a的两端都连接有转动板211b，转动板211b通过转动可以与板主体211a形成不同的角度，灵活的与支撑物5进行固定。
如图10、图11所示，此时板主体211a、转动板211b之间呈90°，两个转动板211b通过紧固件4分别固定在支撑物5的直角面上。当然板主体211a、转动板211b之间的转动角度可以视支撑物5外表面的形状而定，满足不同支撑物5不同角度的定位。
在本申请的另一个实施例中：梯子还包括支撑结构，支撑结构包括支撑支腿30、支撑连接杆31，支撑支腿30分别连接在梯子主体1下部的两侧，此处的下部指的是更靠近梯子底部一端的部位；支撑连接杆31连接在两侧的支撑支腿30之间。
在本实施例中：支撑支腿30包括第一支腿300、第二支腿301，第一支腿300的一端与梯子主体1可转动地连接，具体与梯子主体1的侧杆10的下部可转动连接；第一支腿300的另一端与第二支腿301可滑动地连接，具体为可在第二支腿301的长度方向上滑动；第二支腿301的一端与梯子主体1可转动地连接，具体与梯子主体1的侧杆10的下部可转动连接，但其与侧杆10的转动连接处高于第一支腿300与侧杆10的转动连接处，第二支腿301的另一端为支撑端，支撑连接杆31连接在两侧第二支腿301之间，可以提高梯子支撑的强度。
支撑结构在梯子的使用过程中与梯子主体1形成“人”字形的支撑，加强梯子底部的稳定性。
当然，支撑结构存在另一种简化结构，即支撑结构不包括第一支腿300，仅通过第二支腿301与梯子主体1形成“人”字形的支撑。
在本实施例中，定位结构还可以作为单独的配件，可拆装地连接在所需要的梯子上进行搭配使用，提高梯子在使用过程中的安全性。其结构与实施例一的定位结构相同，在此不再进行赘述。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
