Description

一种手柄和锤击工具
技术领域
本发明涉及一种手柄和包含该手柄的锤击工具。
背景技术
一般常见的铁槌、木槌、斧头等槌击工具，其结构大都系由头部及握柄所构成，以金属一体锻造之槌击工具而言，为增加使用者握持该槌击工具之舒适性，该握柄上将套设有塑料、橡胶等塑性材质所制成之把套，该把套与该握柄间之接固接方式，除利用紧密配合之外，更同时利用黏着剂接着固定，但由于该把套为塑料或橡胶材质，而该槌击工具之握柄系为金属材质，由以往经验可知，二种不同材质之工件藉由黏着剂接合时，固接着界面之表面特性不同，其接着力往往不佳，因此，当该槌击工具长时间使用于碰撞的状态下，握柄与把套的接固便会因为挥击时之横向或直向抛力及撞击时之反作用力而有逐渐松脱之情形，轻者，则把套松动或脱落造成使用上不便，重者，则槌击工随使力方向抛出，造成无法预期的潜在危险。
其次，前述之槌击工具于使用时，因为衔接该头部之握柄系为密实之钢性结构，因此，当该槌击工具一端产生撞击时，其撞击所产生之部份反作用力，往往藉由连接该头部之握柄直接传导至使用者握持处，使得使用者之手部容易因震荡而产生酸痛、麻痹等不适。然多数的敲击工具为配合其作动的工件，皆有做其部分改良以提升效能或避免伤害，其中该些敲击工具以其握部做减震或系防滑功能为最甚者。鉴于多数的敲击工具并未对如何增加减震材料与金属握部之间的牢固结构有进一步的改善，实有不便。

具体实施方式
为了便于说明，图中所标示之 X 、 Y 、 Z 分别为第一方向、第二方向与第三方向，且第一方向、第二方向与第三方向系相互垂直。
本发明的第一个较佳实施例提供了一种锤击工具，其中该锤击工具包括手柄，如图 1~4 所示，手柄包括内芯 20 和围绕内芯 20 的外周设置的握持部，在内芯 20 和握持部之间形成有至少一个腔室 41 。 腔室 41 设置在手柄的至少一个侧边。
较佳地， 握持部包括外减震层 50 ，外减震层 50 与内芯 20 之间设置有内减震层 40 ，腔室 41 设置在内减震层 40 中。内减震层 40 通过先预制后再套在内芯 20 上，或是以射出成型方式直接被注塑在内芯 20 上。手柄还包括套件 30 ，内芯 20 上设置有组装孔 21 ， 套件 30 通过组装件 35 穿过组装孔 21 而固定在内芯 20 上。 外减震层 50 通过先预制后再套在内减震层 40 和 / 或套件 30 的至少一个部位上，或是以射出成型方式直接被注塑在内减震层 40 和 / 或套件 30 的至少一个部位上。
如图 1~4 所示，本实施例的 锤击工具还包括锤头 10 ， 锤头 10 设置于内芯 20 的前端且可为金属材质一体成型制成，但不以此为限。锤头 10 具有头部 11 及柄部 12 ，头部 11 的内部具有至少一个减震槽 13 ，可将减震材料 14 填入于减震槽 13 之中，减震材料 14 可以是硅胶材质或其他软性减震材料。较佳地，减震槽 13 可以开设在头部 11 的内部中央位置，以利头部 11 敲击后可以平均受力减震。头部 11 连接于柄部 12 的一端，柄部 12 的另一端则续接于内芯 20 。并在锤头 10 与内芯 20 之间设置有止挡部 15 ，以作为限制套件 30 位置。
内芯 20 具有组装孔 21 及定位孔 22 ，组装孔 21 开设在内芯 20 靠近止挡部 15 处，定位孔 22 则开设在内芯 20 的后端。
套件 30 具有套头部 31 及自套头部 31 延伸的套接部 32 ，并以一通孔 33 贯穿套头部 31 及套接部 32 。通孔 33 的形状与内芯 20 的横截面形状相匹配，以利套件 30 以通孔 33 套接在内芯 20 上。套接部 32 具有穿孔 34 ，穿孔 34 与组装孔 21 相互对应，以供组装件 35 穿设固定。
如图 3A 所示，当套件 30 沿着第一方向 X 套设在内芯 20 时，可通过通孔 33 将套件 30 沿着内芯 20 推到止挡部 15 处，使得套件 30 的套头部 31 被止挡部 15 限位止挡，以使套头部 31 与止挡部 15 相互组接，并使内芯 20 的组装孔 21 与套接部 32 的穿孔 34 相互对应。再将组装件 35 沿着第二方向 Y 穿设对应的穿孔 34 与组装孔 21 ，以此将套件 30 组接于内芯 20 上。如图 5C 所示，组装件 35 可以是一铆钉结构或一螺栓螺母结构，但不以此为限。以此结构设计，套件 30 沿着第一方向 X 组在内芯 20 后，通过组装件 35 以第二方向 Y 将套件 30 固定在内芯 20 后，因第二方向 Y 相异于第一方向 X ，可防止套件 30 沿着第一方向 X 脱离于内芯 20 。
如图 3B 所示，内芯 20 的定位孔 22 进一步包括定位槽 221 ，并将定位销 23 穿设在定位孔 22 内，定位销 23 由第一销件 231 及第二销件 232 轴向对接构成。在此基础上：第一销件 231 较第二销件 232 长，将凸块 233 设于第一销件 231 上，当第一销件 231 与地二销件 232 轴向对接并且穿设于定位孔 22 后，使得凸块 233 嵌入定位槽 221 中，以防止定位销 23 在定位孔 22 中轴向转动。
内减震层 40 形成有中空部位的腔室 41 ，并将内减震层 40 包覆住内芯 20 且避开套件 30 的位置，如图 5B 所示，在本实施例中，内减震层 40 可先预制后再套在内芯 20 上，或是直接将内减震层 40 以射出成型方式注塑在内芯 20 上。内减震层 40 的材料可以是但不局限于热塑性聚胺基甲酸酯 (Thermoplastic Polyurethane ； TPU) 。内减震层 40 的腔室 41 可 选择地设置有减震材料或气囊。若是气囊结构时，可进一步 填入有 压缩 空气 或是液态物质 ，利用腔室 41 内的 高压 气压 或液态物质 提供弹性，作为吸震减压之用，但不以此为限。 若是 腔室 41 填入有减震材料 时 ，减震材料 可选择地使用 液态硅胶或其他液态减震材料，但不以此为限。如图 5B 所示，内减震层 40 的 腔室 41 可设置在内芯 20 的 至少一个侧边 ，较佳地，内减震层 40 的腔室 41 可设置在内芯 20 的上下二侧。
如图 3B 所示，外减震层 50 包覆住内减震层 40 及套件 30 的套接部 32 。在本实施例中，外减震层 50 可先预制后再套在内减震层 40 及套件 30 的套接部 32 上，或是直接将外减震层 50 以射出成型方式注塑在内减震层 40 及套件 30 的套接部 32 上。外减震层 50 的材料可以是但不局限于热塑性聚胺基甲酸酯 (Thermoplastic Polyurethane ； TPU) 或热塑性橡胶材料 (Thermo Plastic Rubber material ， TPR) 。如图 6 所示，外减震层 50 进一步包括有至少一个检视孔 51 ，检视孔 51 对应内减震层 40 的至少一个部位，通过检视孔 51 可以观查内减震层 30 及其腔室 41 是否有破裂泄漏的情况。如图 7A 所示，通过检视孔 51 可看出内减震层 30 未有破裂泄漏之状态。如图 7B 所示，若内减震层 30 破裂泄漏，可由检视孔 51 看出，内减震层 40 因破裂而漏出于检视孔 51 之中。
如图 8A 及图 8B 所示，为本发明的第二实施例的减震锤击工具于组装的侧视剖面图，其具体实施方式与前述第一实施例大致相同，以下仅就相异之处加以说明，其余相同处不再赘述。
如图 8A 所示，当套件 30 组装于内芯 20 后，可通过组装件 35 将套件 30 固定于内芯 20 上，再将外减震层 50 先预制后再套设在套件 30 的套接部 32 上，或是直接将外减震层 50 以射出成型方式注塑在套件 30 的套接部 32 上。使得外减震层 50 与内芯 20 之间具有容置空间 52 。如图 8B 所示，再将内减震层 40 塞入容置空间 52 中并且包覆住内芯 20 。如图 9A 所示，较佳地，内减震层 40 的腔室 41 可设置在内芯 20 的上下二侧。
如图 8A~8B 所示，接着将一封盖 60 由外减震层 50 后端的开口 53 处塞入。封盖 60 具有盖部 61 及由盖部 61 延伸的至少一个插接部 62 。盖部 61 用以封闭外减震层 50 的开口 53 。插接部 62 通过开口 53 插设到容置空间 52 内，并且插接部 62 具有固定孔 63 。当插接部 62 组入于容置空间 52 后，使得插接部 62 的固定孔 63 对应于内芯 20 的定位孔 22 ，再将定位销 23 由第二方向 Y 穿设对应的定位孔 22 及固定孔 63 ，使得封盖 60 被稳固的组装在外减震层 50 后端，避免封盖 60 由外减震层 50 后端脱离。
综上所述，根据上述本发明所有实施例揭露的锤击工具，在使用敲击时，头部的内部减震槽可通过减震材料作为第一道缓冲和吸收锤头的震动和冲击力，再传递到手柄的内芯上，经过内减震层及其腔室作为第二道吸收缓冲手柄的内芯上传递过来的震动和冲击力，最后再由外减震层作为第三道缓冲和吸收由内减震层传递来的震动和冲击力，通过三道缓冲及减震的结构，大幅减少了使用者操作时的手感受到震动和冲击的感觉。
另外，套件相对于手柄的内芯的结合方向（第一方向）相异于组装件固定套件的固定方向（第二方向），再由外减震层包覆住套件的套接部及组装件，从而防止套件由组装方向脱离于手柄的内芯外。
以上的实施方式详细描述了本发明的几种具体实施例。应当理解，本发明所属技术领域的人员在了解了本发明上述的技术构思、具体实施例和功效，可以根据本发明的技术构思作出诸多的修改和变化。因此，依据本发明的上述技术构思在现有技术的基础上通过逻辑分析、推理或者有限的实验从而获得的技术方案，皆应在本发明的权利要求书所请求的保护范围内。
