Description
- 1. Field of the Invention
- This invention is related to a resistance device for an exercising device and in particular to one which can be readily adjusted and assembled.
- 2. Description of the Prior Art
- It has been found that the conventional resistance device for an exercising bicycle utilizes a cable to connect with an adjuster mounted on a front portion of the exercising bicycle. The adjuster includes an axle provided with a knob so that when the knob is turned, the axle will be rotated to tighten or release the cable thereby adjusting the resistance to the exercising bicycle. However, a relatively large effort is required for adjusting such an adjuster thereby making it unfit for practical use.
- Therefore, it is an object of the present invention to provide an improved resistance device for a physical exerciser which can obviate and mitigate the above-mentioned drawbacks.
- This invention is related to a resistance device for an exercising device and in particular to one which can be readily adjusted and assembled.
- It is the primary object of the present invention to provide a resistance device for a physical exerciser includes a cylindrical housing formed with two diagonally opposite chambers at two opposite sides thereof, a fastener fixedly mounted on an inner side thereof, and a groove formed on an inner side thereof and arranged under the fastener, a pair of actuating rods inserted into a respective one of the chambers and provided with a hook and connected with a spring by a pin, an upper end of the spring being connected with the fastener, a pair of buttons pivotally connected with a top of the cylindrical housing, a tubular axle fitted within the cylindrical housing and provided with a first set of teeth and a second set of teeth which are positioned together beside each other and operate in opposite circular direction, an axle formed with a spiral groove extending through an outer surface thereof, a core member fitted within the tubular axle and having a radial hole aligned with the spiral groove, a pin inserted through the spiral groove so that a lower portion of the pin is fitted into the radial hole of the core member, and a cover fixedly mounted on a cylindrical housing.
- The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
- FIG. 1 is an exploded view of the present invention;
- FIG. 2 is a perspective view of the present invention;
- FIG. 3 illustrates the engagement between the actuating rods and the teeth of the tubular axle; and
- FIGS. 4 and 5 illustrate the working principle of the present invention.
- For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
- With reference to the drawings and in particular to FIGS. 1 and 2 thereof, the resistance device for an exercising device according to the present invention generally comprises a cylindrical housing1, a pair of actuating
rods 2, a pair ofbuttons 3, acore member 5, atubular axle 4 and acover 8. The cylindrical housing 1 is formed with two diagonallyopposite chambers 11 at two opposite sides thereof. Each of thechambers 11 has anopen top 111, afastener 112 fixedly mounted on the inner side thereof, and agroove 113 formed on the inner side thereof and arranged under thefastener 112. The top of the cylindrical housing 1 has a raisedportion 12 formed with twoholes 121. The center of the cylindrical housing 1 is provided with acenter shaft 13. - Each of the actuating
rods 2 is inserted into a respective one of thechambers 11. - The actuating
rod 2 is provided with ahook 21 at the inner side and connected with aspring 23 at the lower end by apin 22. Thepin 22 is also fitted in thegroove 113 and the upper end of thespring 23 is connected with thefastener 112 of the cylindrical housing 1, so that the actuating rod can slide in thechamber 11. - Each of the
buttons 3 is provided with twolugs 31 at two ends thereof. The twobuttons 3 are pivotally connected with two sides of the raisedportion 12 of the cylindrical housing 1 byscrews 32 extending through theholes 311 of the lugs of thebuttons 3 into theholes 121 of theraises portion 12, so that thebuttons 5 can be moved with respect to the cylindrical housing 1. - The
tubular axle 4 is fitted within the cylindrical housing 1 and provided with a first set ofteeth 41 and a second set ofteeth 42 which are positioned together beside each other and operate in opposite circular direction. The first set ofteeth 41 is engaged with thehook 21 of a correspondingactuating rod 2, while the second set ofteeth 42 with thehook 21 of the other actuating rod 2 (see FIG. 3). Further, theaxle 4 is formed with aspiral groove 43 extending through its outer surface. - The
core member 5 has a center hole adapted to sleeve over thecenter shaft 13 and is fitted within thetubular axle 4. Thecore member 5 has aradial hole 51 aligned with thespiral groove 43. Apin 52 is inserted through thespiral groove 43 so that the lower portion of thepin 52 is fitted into theradial hole 51 of thecore member 5. An end of thecore member 5 is formed with ahole 53 having a slot adapted to receive anipple 61 of acable 6. - The
cover 8 is fixedly mounted on the cylindrical housing 1 to keep dust or the like from entering therein. - As the
button 3 is depressed, the correspondingactuating rod 2 will be forced to go downwardly thereby causing the actuatingrod 2 to push the corresponding teeth 41 (or 42) and therefore rotating thetubular axle 4. As thetubular axle 4 is rotated, thepin 52 will move along thespiral groove 43 thereby moving thecore member 5 within thetubular axle 4 and therefore tightening or releasing thecable 6 depending on the rotation direction of the tubular axle 4 (see FIGS. 3, 4 and 5). - Referring to FIG. 3, the
hook 21 of one of the actuatingrod 2 is engaged with the first set ofteeth 41, while thehook 21 of the other actuatingrod 2 with the second set ofteeth 42, so that when thebutton 3 is depressed, the actuatingrod 2 is forced to go downwardly to drive theteeth tubular axle 4. - When the
tubular axle 4 is rotated in the direction as show in FIG. 4, thepin 52 will move along thespiral groove 43 of thetubular axle 4 thereby moving thecore member 4 to go backward and therefore releasing thecable 6. However, as thetubular axle 4 is rotated in an opposite direction, thepin 52 will move along thespiral groove 43 of thetubular axle 4 in an opposite direction thereby moving thecore member 4 to go forward and therefore tightening thecable 6. Hence, the resistance to an exercising device can be easily adjusted by the present invention. - It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
- While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
