Description

Safety dumbbell set

本發明係與啞鈴有關，更詳而言之係指一種安全啞鈴組。The invention relates to dumbbells and, more particularly, to a safety dumbbell set.

按，啞鈴係一種常見而簡易之健身器材，主要用以供使用者之手部抓握並進行抬舉，以強健手臂及其周邊肌肉之肌力。惟，早期之啞鈴係一體成型，因此無法改變配重，導致使用者欲使用不同重量之啞鈴時，必須購買多種不同重量之啞鈴，以致有數量過多不易收納及花費金額過高等問題。因此，目前已有業者研發出一種可調整配重之啞鈴組，其主要係由一啞鈴把、二配重單元及一收納座所組成，該二配重單元分別具有多數個配重塊，該等配重塊係可選擇性地被放置在收納座上或被組接在啞鈴把上，進而達到調整配重之目的。然而，此種啞鈴組之配重塊與啞鈴把間之固定結構過於薄弱，導致配重塊容易在使用者之抬舉、晃動下與啞鈴把間產生鬆動，進而有安全上之疑慮。再者，被放置在收納座上之配重塊，由於與收納座間並未固定，而有容易被使用者錯位放置之情形，導致有重量不正確選擇之問題。Press, dumbbell is a common and simple fitness equipment, mainly used for the user's hand to grasp and lift, to strengthen the muscles of the arm and its surrounding muscles. However, the early dumbbells are integrally formed, so the weight cannot be changed. When the user wants to use dumbbells of different weights, he must purchase a plurality of dumbbells of different weights, so that the number is too large to be stored and the amount of money is too high. Therefore, at present, a dumbbell group capable of adjusting the weight is developed, which is mainly composed of a dumbbell handle, a two weight unit and a storage seat, and the two weight units respectively have a plurality of weights, The weights can be selectively placed on the storage base or assembled on the dumbbell handle to achieve the purpose of adjusting the weight. However, the fixing structure between the weight of the dumbbell group and the dumbbell handle is too weak, so that the weight is easily loosened under the lifting and shaking of the user and the dumbbell handle, thereby having safety concerns. Further, the weight placed on the storage base is not fixed to the storage compartment, and is easily placed by the user, resulting in a problem of incorrect weight selection.

有鑑於此，為改善先前技術中，習知可調整配重之啞鈴有著配重塊與啞鈴把間容易鬆動之安全性問題及容易被錯位放置在收納座上等問題；緣此，本發明乃提供一種安全啞鈴組，其主要包含有：一收納座，具有一座體及位於該座體頂面上之二收納區，該各收納區具有若干並排之收納槽，該收納槽內具有一第一固定部；一啞鈴把，具有一握柄及二分別設於該握柄兩端之選擇單元，該選擇單元具有若干依預定間距排列之選擇盤，該選擇盤之一側面上具有一壓迫單元及至少一釋放空隙，該壓迫單元具有至少一壓迫塊；二配重單元，各配重單元具有若干之配重塊，該配重塊具有二夾塊、一彈簧及一連桿，該二夾塊係相互樞接，而可受外力作用於一內夾位置至一外張位置間進行往復之夾合與展開，該二夾塊間具有一夾槽，該二夾塊之外周面上具有一第二固定部，該彈簧係抵接於該二夾塊間，以提供該二夾塊往外張位置展開之預力，該連桿樞接於該二夾塊間，該連桿之中段具有一樞轉點，可受外力作用於一內縮位置至一外撐位置間進行樞轉；當該配重塊之連桿與該啞鈴把之壓迫單元位置對應時，係由該壓迫單元抵接而將該連桿由內縮位置往外撐位置樞轉，以將該二夾塊夾合至內夾位置，而由該夾槽夾持於該握柄上，該收納座之第一固定部與該配重塊之第二固定部分離，而將該配重塊與該收納座分離並夾持於該啞鈴把之握柄上；當該配重塊之連桿與該啞鈴把之釋放空隙位置對應時，該壓迫單元未接觸連桿，而使該連桿位於內縮位置，使由該彈簧將該二夾塊往外張位置展張，該夾槽與該握柄分離，該收納座之第一固定部與該配重塊之第二固定部卡接，而將該配重塊與握柄分離並留置於該收納座上；藉以增進本發明之安全性。In view of the above, in order to improve the prior art, the conventional weight-adjustable weight dumbbell has the problem that the weight between the weight and the dumbbell handle is easy to loose and the problem that it is easy to be misplaced on the storage seat; therefore, the present invention is A safety dumbbell set is provided, which mainly comprises: a storage base having a body and two storage areas on the top surface of the base body, the storage areas having a plurality of side by side storage slots, the storage compartment having a first a fixing portion; a dumbbell handle having a handle and two selection units respectively disposed at two ends of the handle, the selection unit having a plurality of selection trays arranged at a predetermined interval, the selection tray having a compression unit on a side thereof At least one release gap, the compression unit has at least one compression block; two weight units, each weight unit has a plurality of weights, the weight has two clamps, a spring and a link, the two clamps The two members are pivotally connected to each other, and can be clamped and unfolded by an external force acting between an inner clamping position and an outer elastic position.
