Description

槓鈴
本發明係有關於一種槓鈴。
習知的槓鈴如專利US 8,617,036所揭者,包含一桿體與設於桿體兩端的配重件,而使用者係抓握桿體中間部分,將槓鈴舉起而進行重量訓練,然而,此種結構使得使用者抓握的方向必須呈水平,較為吃力,此外,若要改變抓舉重量,必須拆換配重件,較為不便。
而專利US 8,672,815更揭露一種較新穎的槓鈴,其桿體上設有環狀的部分,環狀部分中央設有抓握桿,藉此,使用者能以鉛直方向抓握,舉起的動作較為容易,然而,要改變重量亦須拆換配重件,仍屬不便,且若要改變兩手抓握位置,必須調整彼此套接的兩桿體,調整不易且改變幅度有限。
專利US8,231,511則揭露一種多功能的槓鈴,係為一中空管狀本體上穿設穿孔而形成抓握部,以提供使用者進行抓握,然而,此類結構無法調整雙手抓握間距與位置,亦不可能調整重量。
本發明之主要目的在於提供一種槓鈴,具有可填充物體的本體與可調整位置且可拆的握持件,能依需求調整重量與握持位置。
為達成上述目的,本發明提供一種槓鈴,包含一本體與二握持件。
該本體概呈空心桿狀而圍構一容置空間,該容置空間供置入液體或固體,該本體定義一長度方向,該本體的外壁形成有至少一定位凹槽;各該握持件中央空心而可移動地套設於該本體上,該握持件具有一定位件,該定位件能選擇性地抵頂至該定位凹槽而使該握持件定位於該本體上,該握持件更具有至少一握持部可供握持。
藉此,使用者能藉由選擇性填充水或砂等物體於該容置空間中來調整重量,並可藉由選擇性抵頂於定位凹槽的定位件來調整握持件相對本體的位置,以符合實際使用需求。

於本發明的主要實施例中,該連結部23內設有一通道231,該通道231連通該外環21的外環壁與該內環22的內環壁,該通道231靠近該外環21的外環壁的一端定義為一第一端,該通道231靠近該內環22的內環壁的一端定義為一第二端,該通道231靠近該第二端的開口內徑小於該通道231其他部分的內徑而形成一階梯面2311,該定位件30包含一外殼31、一抵頂件32、一轉動件33、一齒件34、一按壓件35、一第一彈性件36與一第二彈性件37,該外殼31設於該通道231中且該外殼31內壁沿該通道231的延伸方向設有複數個彼此間隔排列的短槽311與長槽312,各該短槽311與長槽312靠近該第一端的一端為封閉狀,各該短槽311與長槽312靠近該第二端的一端具有一開口,任二相鄰的短槽311與長槽312開口之間形成一第一斜面313,各該短槽311的封閉端較各該長槽312的封閉端靠近該通道231的第二端,該抵頂件32具有一環緣321,該第一彈性件36套設於該抵頂件32且抵頂於該環緣321與該通道231的階梯面2311 之間,該齒件34較靠近該第二端的一端端面設有複數斜齒341,該齒件34能於該外殼31中沿該通道231的延伸方向滑動但無法相對該外殼31轉動(具體來說,該外殼31內壁凹設有至少一溝槽314,該溝槽314沿該通道231延伸方向延伸,該齒件34外壁設有至少一凸塊342,該凸塊342滑設於該溝槽314),該轉動件33設於該抵頂件32與該齒件34之間而能相對該抵頂件32與該齒件34轉動,該轉動件33外壁形成有複數個沿該通道231延伸方向延伸的縱肋331,各該縱肋331朝向該齒件34的端面形成一第二斜面3311,各該縱肋331滑設於其中一短槽311或長槽312且其第二斜面3311選擇性地受該齒件34的斜齒341抵頂,該按壓件35設於該通道231的第一端而與該齒件34連結並同動,該第二彈性件37設於該齒件34內部而彈設於該齒件34與該轉動件33之間,當該按壓件35受按壓而朝該第一端方向推迫該齒件34,該齒件34將該轉動件33的縱肋331推出該短槽311或該長槽312,該第二斜面3311沿該第一斜面313滑動而使該轉動件33轉動,該縱肋331便進入相鄰的短槽311或長槽312中,當該些縱肋331位於該短槽311中時,該抵頂件32凸出於該內環22的內環壁之外(如同圖3與圖3A所示),當該些縱肋331位於該長槽312中時,該抵頂件32位於該通道231中而不凸出於該內環22的內環壁之外(如同圖6與圖6A所示)。
必須說明的是,本發明主要實施例中,該本體10係具有二長溝12分別位於徑向上的兩端,各該握持件20亦具有二定位件30分別位於徑向上的兩端而與該二長溝12底部的長形滑槽121對應,當該二定位件30皆位於該第一位置時,該二定位件30抵頂於該二長形滑槽121而如同夾掣該本體10一般,使該握持件20無法相對該本體10滑動。
於本發明的其他可能實施例中,亦可具有複數個定位凹槽,該些定位凹槽沿該本體長度方向間隔排列,各該握持件的定位件可選擇性抵頂於其中一定位凹槽以達到多段式位置調整的效果而與本發明主要實施例類似。
實際使用時,使用者能以雙手分別握持該二握持件20的握持部,將該二握持件20連同該本體10舉起等,以進行訓練,而欲調整兩手握持間距時,可按壓各定位件30的按壓件35,使抵頂件32縮入,即可使握持件20沿該本體10滑動,將握持件20移動至適當位置後,再次按壓該按壓件35,使抵頂件32凸出抵頂於長形滑槽121,即可完成握持件20的定位,方便進行後續訓練工作。
特別要說明的是,由於該本體10具有容置空間11可選擇性地填充水或砂等物體,因此,使用者能依照需求調整本體的重量,十分便利。
綜上所述,本發明提供之槓鈴具有可填充物體的本體而能隨意調整重量且易於收納,並具有定位件能隨意調整、定位該握持件相對本體的位置,操作簡單,且握持件本身亦有配重效果,實為結構簡便、容易依需求調整,極具進步之效。
