KR20120066136A - Dumbbell shaft - Google Patents

Abstract

It relates to a dumbbell shaft designed to increase the convenience of the dumbbell replacement. A plurality of uneven parts 2 and fixing grooves 9 are formed around the iron bar 1 to which the fixed body 3 is coupled, and an elastic member 7 is formed on the inner surface of the elastic member 6 of the fixed body 3. ) And the elastic member 6, the key (10).
The present invention is automatically fixed by the key 10 and the concave-convex portion 2 when combining the iron bar (1) and the fixed body (3). Even when disassembling the coupling can be easily replaced by pressing the switch 5 of the fixed body (3).

Description

Dumbbell Shaft

The present invention relates to the shaft of the dumbbell when the fixed body (3) is fixed to the iron bar, the combination of the iron bar (1) and the fixed body (3) without a separate operation. The iron bar (1) is coupled to the weight body of the dumbbell in order up to the fixed jaw (11) and the fixed body (3) to be in close contact with the weight body. At this time, the key 10 of the fixed body (3) is combined with the concave-convex portion (2), the weight body is firmly coupled to the iron bar (1). When the switch 5 of the fixed body 3 is pressed, the elastic member 7 under the switch 5 is pressed and the key 10 is lifted from the elastic member 6 as a starting point. At this time, the coupling of the fixed body 3 and the iron bar 1 disappears and the weight can be easily separated.

The present invention relates to a shaft of the dumbbell, and adds the convenience of detachment to the fixed body for fixing the weight of the dumbbell.

Existing dumbbells will be combined with the iron rod and the fixed body through the means of fixing bolts or caps. In the usual way, the fixing body should be tightened to fix the weight to the steel bar. When dismantling the iron rod and the fixed body, it is a cumbersome process because dismantling is performed in the same way as before.

In the present invention, the fixed body is not flowed, and the work process is simplified and the price is concluded.

The present invention is intended to provide convenience in use by adding a structure that can be firmly coupled to the fixed body to the iron bar and the weight can be fixed and the hatchelle easily.

Dumbbell shaft to achieve the above object includes an iron rod having an uneven portion and a fixed body having a fixing function. In addition, the elastic member of the fixed body is characterized in that it is used to have a restoring force to its original state when the switch is pressed without pushing up the fixed shaft.

The present invention eliminates the hassle of removing and removing the weight and shorten the time because there is no inconvenience of coupling and dismantling the fixed bolt type or tightening cap type of the existing dumbbell structure.

1. Iron bar 2. Uneven part 3. Fixed body
4. Fixed body 5. Switch 6. Elastic member
7. Elastic member 8. Anti-slip 9. Fixing groove
10. Key 11. Jaw

Hereinafter, with reference to the accompanying drawings, the specific content of the present invention will be described.

 When the fixed body 3 is coupled to the iron bar 1, the key 10 of the fixed body 3 is pushed by the uneven portion 2 of the iron bar 1, and is closed by the elastic member 7 Has

 The elastic member 6 serves as a lever for moving the switch 7 and the key 10 in opposite directions and is a core structure of coupling and dismantling.

 The uneven parts of the bar should be placed at appropriate intervals to match the coupling length of the weight.

Claims (3)

Shaft of dumbbell with uneven shaft and fixed body
The shaft bar of the dumbbell according to claim 1, wherein the key rod 10 is fitted to the iron rod 1 to which the fixed body 3 is coupled.
 2. A shaft of a dumbbell according to claim 1, having an elastic member (6) between the key (10) and the switch (5).
