Abstract

A pull exerciser includes two attachment members, two positioning devices respectively attached to the attachment members at a location opposite to a grip portion of an associated attachment member, and at least one resilient cord. Each positioning device includes a positioning block and a positioning plate removably received in the positioning block. Each of the positioning blocks and the positioning plates includes at least one positioning hole. The resilient cord has two ends extendible through the positioning hole of each positioning block and each positioning plate. An end piece is fixed to each end of the resilient cord. The end pieces of the resilient cord are mounted to at least one of the positioning plates.

Claims

1. A pull exerciser comprising:

two attachment members each having a grip portion;

two positioning devices respectively attached to the attachment members at a location opposite to the grip portion of an associated one of the attachment members, each said positioning device including a positioning block and a positioning plate removably received in the positioning block, each of the positioning blocks and the positioning plates including at least one positioning hole; and

at least one resilient cord having two ends extendible through said at least one positioning hole of each said positioning block and each said positioning plate, an end piece being fixed to each of the ends of said at least one resilient cord, the end pieces of said at least one resilient cord being mounted to at least one of the positioning plates.

2. The pull exerciser as claimed in claim 1, with each said positioning block comprising a compartment for fittingly receiving an associated one of the positioning plates.

3. The pull exerciser claimed in claim 1, with each said attachment member being a belt, and with the pull exerciser further comprising a tubular handle mounted around each said belt.

4. The pull exerciser as claimed in claim 3, with each said positioning block comprising two slots in two sides thereof, with each said belt extending through the slots of an associated one of the positioning blocks.

5. The pull exerciser as claimed in claim 1, with each said attachment member being adjustable in length.

6. The pull exerciser as claimed in claim 1, with said at least one positioning hole of each said positioning block having a diameter greater than that of the end pieces of said at least one resilient cord.

7. The pull exerciser as claimed in claim 1, with said at least one positioning hole of each said positioning block having a diameter smaller than that of the end pieces of said at least one resilient cord, said at least one positioning hole of each said positioning block being communicated with outside via a reduced opening having a width smaller than a diameter of said at least one positioning hole of each said positioning block, allowing said at least one resilient cord to be inserted into said at least one positioning hole of each said positioning block via the reduced opening of said at least one positioning hole of each said positioning block.

8. The pull exerciser as claimed in claim 6, with each said positioning block further comprising at least one second positioning hole having a diameter smaller than that of the end pieces of said at least one resilient cord, said at least one second positioning hole of each said positioning block being communicated with outside via a reduced opening having a width smaller than a diameter of said at least one second positioning hole of each said positioning plate, allowing said at least one resilient cord to be inserted into said at least one second positioning hole of each said positioning block via the reduced opening of said at least one second positioning hole of each said positioning block.

9. The pull exerciser as claimed in claim 6, with said at least one positioning hole of each said positioning plate having a diameter smaller than that of the end pieces of said at least one resilient cord, said at least one positioning hole of each said positioning plate being communicated with outside via a reduced opening having a width smaller than a diameter of said at least one positioning hole of each said positioning plate, allowing said at least one resilient cord to be inserted into said at least one positioning hole of each said positioning plate via the reduced opening.

10. The pull exerciser as claimed in claim 7, with said at least one positioning hole of each said positioning plate having a diameter smaller than that of the end pieces of said at least one resilient cord, said at least one positioning hole of each said positioning plate being communicated with outside via a reduced opening having a width smaller than a diameter of said at least one positioning hole of each said positioning plate, allowing said at least one resilient cord to be inserted into said at least one positioning hole of each said positioning plate via the reduced opening.

11. The pull exerciser as claimed in claim 8, with said at least one positioning hole of each said positioning plate having a diameter smaller than that of the end pieces of said at least one resilient cord, said at least one positioning hole of each said positioning plate being communicated with outside via a reduced opening having a width smaller than a diameter of said at least one positioning hole of each said positioning plate, allowing said at least one resilient cord to be inserted into said at least one positioning hole of each said positioning plate via the reduced opening.

12. The pull exerciser as claimed in claim 10, with said reduced opening of said at least one positioning hole of each said positioning plate facing in a direction opposite to that of an associated one of the reduced openings of an associated one of the positioning blocks.

13. A pull exerciser comprising:

two tubular handles;

two belts that are adjustable in length, each said belt extending through an associated one of the tubular handles;

two positioning devices respectively attached to the belts at a location opposite to an associated one of the tubular handles, each said positioning device including a positioning block and a positioning plate removably received in the positioning block, each of the positioning blocks and the positioning plates having a plurality of positioning holes, each said positioning hole of each said positioning plate being communicated with outside via a reduced opening having a width smaller than a diameter of each said positioning hole of each said positioning plate; and

a plurality of resilient cords each having two ends, each said end of each resilient cord being insertable into an associated one of the positioning holes through the reduced opening of the associated positioning hole, each said resilient cord being extendible through the positioning holes of each said positioning block, an end piece being fixed to each of the ends of each said resilient cord and having a diameter greater than the diameter of each said positioning hole of the positioning plates, at least one of said resilient cords being selectively attached to the positioning devices.

14. The pull exerciser as claimed in claim 13, with the resilient cords having different elastic coefficients.

15. The pull exerciser as claimed in claim 13, with each said positioning hole of each said positioning plate being aligned with an associated one of the positioning holes of an associated one of the positioning blocks.

16. The pull exerciser as claimed in claim 13, with each said attachment member being adjustable in length.

17. The pull exerciser as claimed in claim 13, with each said positioning hole of each said positioning block having a diameter greater than that of the end pieces of each said resilient cord.

18. The pull exerciser as claimed in claim 13, with each said positioning hole of each said positioning block having a diameter smaller than that of the end pieces of each said resilient cord, each said positioning hole of each said positioning block being communicated with outside via a reduced opening having a width smaller than a diameter of each said positioning hole of each said positioning block, allowing each said resilient cord to be inserted into the positioning holes of the positioning blocks via the reduced opening of each said positioning hole of each said positioning block.
