Description

可拆卸式滚轮装置和移动式箱包 技术领域
本发明涉及一种可拆卸式滚轮装置以及一种具有这样的可拆 卸式滚轮装置的移动式箱包。 背景技术
现在人们的生活越来越丰富， 在工作、 运动、 休闲等活动中 经常会使用到箱包， 特别是带有万向角轮的移动式箱包。 然而， 当在工作或旅行结束的时候， 需要把包放好， 有轮子的箱包不易 固定； 当要外出运动， 如去健身、 打高尔夫、 游泳等带的行李不 多也不少， 但不想拎包， 就可以带着有轮子的包， 轻松的出行。 现有带有万向角轮的移动式箱包， 万向角轮是固定在箱体上的， 不管转动多少度， 都不能拆卸下来， 在使用时适应性差。 另外， 轮子是箱包中磨损最快的部件之一， 当一个箱包还很好， 而轮子 被磨损不能正常使用的时候， 想要自己轻松换上新的轮子， 但轮 子不能拆卸下来， 给使用者造成不便。
此外已知一种卡扣式的可拆卸式滚轮装置， 在这种滚轮装置 中， 卡扣连接结构必须设计得非常牢固， 以便防止滚轮因外部载 荷的作用而无意地脱落， 这使得通常需要借助于工具或者需要消 耗非常大的力气才能解除该卡扣连接结构。 而且这种卡扣连接结 构的牢固性随着拔出操作次数的增加而降低。 发明内容
本发明的目的在于， 提供一种可拆卸式滚轮装置以及一种具 有这样的可拆卸式滚轮装置的移动式箱包， 其中可拆卸式滚轮装 置不仅能持久地防止滚轮的无意的脱落， 而且允许容易的安装和 拆卸。
上述目的按本发明如下解决，即提出一种可拆卸式滚轮装置， 包括滚轮座和滚轮组件， 滚轮组件与滚轮座可拆式连接； 滚轮座 具有通孔， 滚轮座在上方具有与通孔成横向的、 尤其是与通孔垂 直的导向部， 弹簧预紧的按钮板在该导向部中引导， 该按钮板具 有一个穿过滚轮座中的按钮通孔的、 能从外部作用的按钮臂， 通 过操作按钮臂使得按钮板沿着导向部移动； 滚轮组件具有滚轮架 和绕滚轮轴可旋转地支承在滚轮架上的滚轮， 在滚轮架的上部设 置一个凸台和一个从凸台伸出的、 用于插入通孔中的轴， 在该轴 上设置上端卡位； 在安装状态时， 滚轮组件的凸台与滚轮座的底 部贴紧， 并且沿着轴的插入方尚看， 按钮板弹簧预紧地嵌入到滚 轮组件的上端卡位后面， 并且按钮板能克服弹簧预紧力脱离与上 端卡位的作用。
在本发明的可拆卸式滚轮装置中， 通过用一只手拨开按钮臂 和用另一只手插入滚轮组件， 然后松开按钮臂， 就能容易地安装 滚轮组件。 在安装状态时， 通过弹簧预紧的按钮板与上端卡位的 相互作用， 以及通过凸台与滚轮座底部的贴紧， 实现滚轮组件与 滚轮座之间的持久的牢固连接， 防止滚轮组件的无意脱落。 在需 要拆除滚轮组件时， 只需要用一只手拨开按钮板， 就可以用另一 只手毫不费力地取下滚轮组件。 在滚轮磨损时也可以容易地更换 滚轮组件。
在一种有利的实施形式中， 所述可拆卸式滚轮装置构成为可 拆卸式的万向滚轮装置， 其中滚轮架能绕一条纵轴线自由旋转。 滚轮装置的万向性， 即滚轮架能绕纵轴线的自由旋转性， 能通过 多种不同的方式实现， 而且由现有技术也是公知的。 例如， 滚轮 架能绕一条由所述轴确定的纵轴线自由旋转， 所述纵轴线特别是 基本上垂直于滚轮轴的轴线。 在一种有利的结构中， 凸台与所述 轴抗旋转地连接， 而滚轮架能绕所述轴旋转。 在另一种可选择的 结构中， 滚轮架与所述轴抗旋转地连接， 而所述轴能在通孔中自 由旋转。 此外， 滚轮架能绕纵轴线的有限转动性或者非转动性也 是可考虑的。
在一种有利的实施形式中， 轴具有一个沿其插入方向看位于 上端卡位后面的中间卡位， 并且上端卡位与中间卡位之间的间距 等于按钮板的厚度。 因此在安装状态时按钮板嵌入上端卡位与中 间卡位之间并同时与上端卡位、 中间卡位作用， 有利于轴的特别 可靠的轴向固定。
在一种有利的实施形式中， 在轴上构成一个环绕的凹槽， 该 凹槽的上下两个槽壁分别构成上端卡位和中间卡位， 并且按钮板 具有与凹槽的形状适配的弧形槽。
在一种有利的实施形式中， 滚轮座在其底部具有一个凹部， 滚轮组件的凸台与该凹部具有互补的形状， 并且在安装状态时相 互贴紧。
在一种有利的实施形式中， 滚轮组件的凸台与滚轮座的凹部 具有平面式的贴合表面， 并且具有非圆形的轮廓。 在该实施形式 中， 不仅实现轴的特别可靠的轴向定位， 而且实现凸台的抗旋转 的固定以及较小的结构尺寸。
在一种有利的实施形式中， 弹簧沿着导向部的方向布置， 弹 簧的一端与按钮板固定， 尤其是固定在按钮板的一个突起上， 该 弹簧的另一端与滚轮座上的、 优选构成为突起或凹陷的弹簧固定 装置固定。
在一种有利的实施形式中，在按钮通孔中设置一个按钮外件， 按钮外件与按钮臂连接或者构成一体， 通过操作按钮外件能使按 钮板沿着导向部移动。 通过按钮外件能够友好地操作按钮板。
在一种有利的实施形式中， 滚轮座的上表面设有可拆的、 尤 其是螺纹连接的外壳盖， 用于遮盖滚轮座中的零件。 可拆的外壳 盖有利于滚轮座中的零件尤其是弹簧的维护。 例如当弹簧失效时 或者异物进入到滚轮座中时， 可以通过打开外壳盖来更换弹簧或 者去除异物，避免滚轮座的失灵，从而避免整个滚轮装置的失灵。
在一种有利的实施形式中， 滚轮座与箱包可拆式连接， 尤其 是螺纹连接。
本发明的目的也通过一种移动式箱包达到， 所述移动式箱包 具有本发明的可拆卸式滚轮装置， 其中滚轮座安装在箱包上， 尤 其是螺纹连接在箱包上。
在一种有利的实施形式中， 在箱包的底部两侧分别设置一个 可拆卸式滚轮装置。 附图说明

下面结合附图和实施例对本发明作进一步说明。 在附图所示 的实施例中，本发明的滚轮装置构成为可拆卸式的万向角轮装置， 在箱体的两个角部上分别安装 个作为角轮装置的滚轮装置。 同 样可设想， 在箱体的其它部位上安装本发明的可拆卸式的滚轮装 置。 如图所示， 这种可拆卸式万向角轮装置， 主要包括滚轮座 1
(在此为角轮座）， 角轮座 1通过螺栓 1-5与箱体连接固定， 角轮 座 1下部设有滚轮 3， 角轮座 1与滚轮 3之间通过连接装置 2连 接， 角轮座 1的上表面设有外壳盖 1-6， 外壳盖 1-6设为弓形， 便 于内部弹簧 2-2的活动，外壳盖 1-6通过螺丝 1-7和螺丝孔 1-8固 定连接在角轮座 1上， 角轮座上设有通孔 1-1 , 角轮座 1的侧面 开有按钮通孔 1-3， 按钮通孔 1-3内设有按钮外件 1-4。 连接装置 2上设有凸台 2-5， 连接装置 2内设有旋转头装置 2-6， 旋转头装 置 2-6穿过通孔 1-1及凸台 2-5， 旋转头装置 2-6上设有轴 2-8， 轴 2-8上设有上端卡位 2-9和中间卡位 2-7， 轴 2-8的底部有圆盘 2-4， 轴 2-8将旋转头装置 2-6和滚轮 3相连接， 中间卡位 2-7位 于凸台 2-5上方。 按钮板 2-10可移动地设在角轮座 1中的一个与 通孔 1-1成横向的导向部中， 该导向部尤其是构成为直线导轨， 按钮板 2-10沿竖直方向位于上端卡位 2-9和中间卡位之间 2_7, 按钮板 2-10上设有弧形槽 2-1， 弧形槽 2-1与旋转头装置 2-6相 配合， 按钮板 2-10上连接有弹簧 2-2， 弹簧 2-2的一端与按钮板 2-10固定， 另一端与角轮座 1上的弹簧固定装置 1-2固定， 按钮 板 2-10上设有按钮臂 2-3， 按钮臂 2-3与按钮外件 1-4连接， 按 钮外件 1-4的设计便于操作。
本发明的滚轮装置大部分由塑料制成， 其中按钮板 2-10、 按 钮外件 1-4和轴 2-8特别是由不锈钢或者镀有防锈层的金属或其 它耐腐蚀的金属制成。
轴 2-8和通孔 1-1可以具有任意适宜的横截面形状， 例如圆 形或方形的横截面。 有利的是， 轴 2-8和通孔 1-1 的外形构造得 彼此配合， 由此通过轴 2-8和通孔 1-1的配合也能实现轴在通孔 中的径向定位。 轴 2-8和通孔 1-1的非圆形的横截面也能实现轴 在通孔中的抗旋转的固定。 如图 5所示， 本发明所述的可拆卸式角轮装置用于移动式箱 包上， 在移动式箱包的箱体 4底部两侧各装有一个如上所述的角 轮座 1。
在拆卸滚轮组件 （在如图所示实施例中为角轮组件） 时， 用 手向水平方向拨开按钮外件 1_4，由于按钮外件与按钮臂 2-3适配 连接， 使得与按钮板 2-10连接的弹簧 2-2收缩， 从而按钮板 2-10 上的弧形槽 2-1就和旋转头装置 2-6失去卡牢作用， 此时用另一 只手将滚轮 3往下拉出， 就能将滚轮组件从箱包上毫不费力地拆 卸下来。 当需要将滚轮组件安袭上去的时候， 一手拿滚轮组件对 准角轮座 1的通孔 1-1往上穿， 另一只手拨开按钮外件 1-4， 在滚 轮组件卡到位后， 松开按钮外件 1-4， 滚轮组件就安装在角轮座 1 上了。
可拆卸式的结构便于在使用过程中， 可根据需要随意安装或 拆卸滚轮组件， 当滚轮磨损时， 便于拆卸更换， 不妨碍箱体其他 部件的继续使用。
除上述实施例外， 凡采用等同替换或等效变换形成的技术方 案， 均落在本发明要求的保护范围。 例如不同于附图所示的实施 例， 在该实施例中按钮板 2-10和外壳盖 1-6等零件设置在滚轮座 1 的上侧， 同样可以考虑将它们设置在滚轮座 1 的下侧。 在这种 情况下， 滚轮座在上侧是封闭的， 而在下侧设置导向部和按钮板
2-10, 外壳盖 1-6朝下基本上封闭滚轮座 1， 外壳盖 1-6相应地具 有通孔 1-1并且在安装状态时直接与凸台 2-5贴紧， 并且例如也 在外壳盖 1-6的底部构造与凸台 2-5的轮廓对应的凹部。 另外， 导向部不设置在滚轮座的基体上而是设置在外壳盖上同样属于等 同的措施。 附图标记列表
