Abstract

An exercise-cord anchored device is used to detachably secure an anchoring end of an elastic cord, and includes an anchored mount, a biasing member, and a tubular insert. The anchored mount has an inner tubular wall defining an insert opening and having an inserting route, a seat, and a rest wall. The biasing member is disposed in the insert opening. The tubular insert is coupled to the elastic cord, is insertable into the insert opening and is manually movable against the biasing force of the biasing member, and has a protuberance configured to be guided along the inserting route. When the mounting end is pushed manually to permit the protuberance to extend beyond the seat, the protuberance is turned angularly over the seat so as to abut against the rest wall, thereby retaining the tubular insert to the anchored mount.

Claims

an anchored mount having

upper and lower surfaces which are opposite to each other in a lengthwise direction

an inner tubular wall which extends from said lower surface along an axis oriented in the lengthwise direction toward said upper surface and which defines an insert opening,

an inserting route which is disposed on said inner tubular wall and which extends in the lengthwise direction from said lower surface toward said upper surface,

a seat which is disposed on said inner tubular wall and behind said inserting route in a clockwise direction, and

a rest wall which is disposed on said inner tubular wall and behind said seat in the clockwise direction, and which is disposed inwardly from said seat relative to said upper surface so as to cooperate with said seat to define a concavaity;

a biasing member disposed in said insert opening and having a connected end secured relative to said upper surface, and an urging end disposed to be movable between a partially extended position where said urging end is closer to said upper surface, and a fully extended position where said urging end is biased against said seat with a biasing force;

a tubular insert adapted to couple with the anchoring end of the elastic cord, having a mounting end which is configured to be insertable into said insert opening so as to permit said tubular insert to be manually moved toward said upper surface against the biasing force to as to displace said urging end to the partially extended position, and a protuberance disposed on said mounting end of said tubular insert, and configured such that, by virtue of guiding said protuberance a long said inserting route, said mounting end is pushed manually against the biasing force, and such that, once said protuberance is brought to extend beyond said seat by virtue of displacing said urging end to the partially extended position, said protuberance is turned angularly over said seat so as to be snapped into said concavity, thereby abutting against said rest wall; and

an abutment member which is disposed in and movable relative to said insert opening in the lengthwise direction between proximate and distal positions relative to said lower surface that correspond to the fully and partially extended positions, and which has an urged surface biased by said urging end of said biasing member, and a press surface disposed to abut against said seat when said abutment member is at the proximate position;

wherein said insert opening extends through said upper surface, said exercise-cord anchored device further comprising an end cap disposed to be engaged with said upper surface to cover said insert opening, and having a positioning protuberance that is formed on a bottom surface thereof and that engages said connected end of said biasing member, said abutment member further having a positioning protrusion formed on said urged surface for engaging said urging end of said biasing member.

2. The exercise-cord anchored device according to claim 1, wherein said anchored mount has a guideway which is disposed on said inner tubular wall and which extends in the lengthwise direction to terminate at the proximate and distal positions, said abutment member being configured to be guided by said guidway to non-rotatably move between the proximate and distal positions.

3. The exercise-cord anchored device according to claim 2, wherein said abutment member is configured to abut against said mounting end of said tubular insert and said protuberance when said protuberance abuts against said rest wall.

4. The exercise-cord anchored device according to claim 3, wherein said abutment member has a notch portion formed along a periphery of said abutment member and extending through said urged and press surfaces so as to be guided by said guideway to non-rotatably moved between the proximate and distal positions, said anchored mount having a barrier wall disposed on said inner tubular wall and extending from said lower surface toward said guideway and behind said rest wall in the clockwise direction such that, when said protuberance is snapped into concavity and abuts against said rest wall, said protuberance abuts against said barrier wall so as to be non-rotatably retained in said concavity.

5. The exercise-cord anchored device according to claim 1, wherein said anchored mount is formed with a notch adjacent to said upper surface, said end cap being formed with a projection disposed outwardly and radially of a periphery thereof for engaging said notch.

6. The exercise-cord anchored device according to claim 1, wherein said tubular insert has a flange spaced apart from said mounting end in the lengthwise direction and having an outer diameter larger than that of said inner tubular wall so as to abut against said lower surface when said protuberance is bought to extend beyond said seat.

7. The exercise-cored anchored device according to claim 1, wherein said biasing member is a coil spring, and has a dimension gradually increased from said connected end to said urging end.

8. The exercise-cord anchored device according to claim 1, further comprising a transverse rod extending in a direction transverse to the lengthwise direction, two of said anchored mounts being disposed on opposite ends of said transverse rod.

9. The exercise-cord anchored device according to claim 1, further comprising a grasp member having a grasp portion disposed to be spaced apart from said anchored mount in the lengthwise direction and a mounting portion disposed for mounting said anchored mount, and a connector interconnecting said grasp portion and said mounting portion.

10. An exercise-cord anchored assembly adapted for detachably securing thereto a plurality of anchoring ends of elastic cords, comprising:

a plurality of anchored mounts angularly displaced from one another about a mounting axis, each having

upper and lower surfaces which are opposite to each other in a lengthwise direction that is transverse to the mounting axis,
