Definitions
- EXERCISING APPARATUS TECHNICAL FIELD relates to improvements in and relating to exercising apparatus of the type adapted to be used by humans to exercise muscles and other body parts.
- the present invention has been devised with the aforementioned current deficiencies and disadvantages in mind, and it has for its principal object the provision of improved exercising apparatus having novel features whereby it will be safer and more effective than known types in relation to portability and adjustability in particular.
- the invention also aims to provide such novel forms of exercising apparatus which will use non-recoil principles and which can be adapted to use in different applications so that any desired muscle can be exercised, while infinitely variable resistance can be utilised as required.
- Other objects and advantages of the invention will be hereinafter apparent.
- the invention resides broadly in exercising apparatus including: an elongate frame; a longitudinal hydraulic main cylinder housed in or forming part of said frame, one end of said main cylinder being fixedly mounted relative to a mounting end of said frame; sealing means at the other end of said main cylinder through which a plunger rod is sealably slidable axially of said main cylinder; handle means associated with that end of said plunger rod which is external of said main cylinder; a main piston at the end of said plunger rod within said main cylinder and mounted in sealably slidable manner to define two opposite sides of said main cylinder; adjustable aperture means interconnecting said two sides of said main cylinder for adjustably varying the permitted flow of hydraulic liquid from one to the other of said opposite sides upon movement of said plunger rod and said main piston; a displacement cylinder mounted on said frame and having one of its ends in liquid communication with said main cylinder at one of said two opposite sides thereof, and a closure piston mounted in sealably slidable manner in the other end
- the displacement cylinder is preferably in spaced parallel relationship to the main hydraulic cylinder and suitably of smaller diameter, but if desired the displacement cylinder could be around and coaxial with the main cylinder.
- the adjustable aperture means is provided in and extending through said main piston between the two opposite sides of said main cylinder, there being provided adjustment-control means for said adjustable aperture means leading operatively from said main piston to said handle means.
- said main piston includes a fixed piston member secured rigidly to said plunger rod, and an adjustable piston member adjustably rotatable about the axis of said main piston and said plunger rod relative to said fixed piston member, there .being apertures through both said piston members adapted to be brought into selected degrees of register to vary the permitted flow according to the rotational disposition of said adjustable piston member, said adjustment-control means comprising a control rod passing rotatably through a bore of said plunger rod and extending from said adjustable piston member to said handle means, rotation-control means being provided at the handle means end of said control rod whereby the latter may be rotated to a desired extent to adjust the setting of said adjustable piston member relative to said fixed piston member.
- the fixed piston member and adjustable piston member are suitably of disc-like form with flat co-acting faces in normally-sealing rotatable contact
- the apertures may include part-circumferential peripheral slots in each disc-like piston member for registering to desired extent upon adjustment of said adjustable piston member.
- the apertures may include a series of cylindrical apertures arranged on an arc about the plunger rod axis through each piston member and inwardly of the periphery thereof, the apertures of the two piston members being arranged to register to desired extent upon adjustment of said adjustable piston member.
- the displacement cylinder has its said one end communicating with said main cylinder at the side of the latter having said sealing means through which said plunger rod passes, the parts being so made and arranged that liquid under pressure at said end of the displacement cylinder acts also to increase the sealing ability of said sealing means against leakage of liquid past said sealing means to the exterior of the main cylinder.
- the sealing means may include two spaced U- shaped sealing rings or buckets through which the plunger rod passes, the space between said rings having an entry port from the adjacent end of the displacement cylinder, a radially-apertured spacer sleeve being provided to surround the plunger rod and maintain spacing of the sealing rings.
- the closure piston may be operatively connected to said plunger rod by coupling means whereby movement of the plunger rod causes a corresponding predetermined movement of the closure piston while maintaining said liquid-filled condition of said main cylinder, the diameter of the closure piston and displacement cylinder being less than the diameter of the main cylinder and main piston so that said predetermined movement of the closure piston is over a lesser length than the movement of the plunger rod.
- the coupling means may include a single cable and pulley arranged so that withdrawal of the plunger rod causes movement of the closure piston in the direction towards that end of the displacement cylinder communicating with said main cylinder.
- the coupling means may include a single cable and plurality of pulleys arranged so that withdrawal of the plunger rod positively and instantly draws the closure piston in the direction towards that end of the displacement cylinder communicating with said main cylinder, while the return movement of the plunger rod positively and instantly draws the closure piston in the direction away from that end of the displacement cylinder communicating with said main cylinder.
- the coupling means may include rack and pinion means instead of the cable and pulleys.
- Fig. 1 shows in perspective view one form of exercising apparatus according to the invention, with the plunger rod and other movable components in inoperative or stored disposition;
- Fig. 2 is a similar perspective view to that of Fig. 1, but with the components in operative or withdrawn disposition, the plunger rod being withdrawn;
- Fig. 3 is a sectional front elevational view of the apparatus of Fig. 1, with outer coverings and certain lines denoting cables omitted for the sake of clarity;
- Fig. 4 is the same as Fig. 3, but showing the components in operative or withdrawn disposition
- Figs. 5 and 6 are side elevational views, corresponding to Figs. 4 and 5 respectively, but schematically showing the cable arrangements;
- Fig. 7 shows diagrammatically in sectional front elevation, a second embodiment of the invention in its simplest form, the plunger rod and other movable components being in inoperative or stored disposition;
- Fig. 8 is the same as Fig. 7, but showing the components in operative or withdrawn disposition
- Figs. 9A and 9B show diagrammatically the co- acting of the two piston members of the apparatus of Figs. 7 and 8, in inoperative and operative dispositions, respectively, of said piston members;
- Figs. 10 and 11 are views similar to Figs. 7 and 8 respectively, showing a third embodiment of the invention.
- Figs. 12A and 12B show diagrammatically the co- acting of the two piston members of the apparatus of Figs. 10 and 11, in inoperative and operative dispositions, respectively, of said piston members, and Figs. 13 and 14 are views similar to Figs. 10 and 11, but showing a fourth embodiment of the invention, employing rack and pinion means in lieu of the cable and pulleys system of the first embodiment of Figs. 1 to 6.
- FIG. 1 and 2 The various embodiments of the invention will illustrate that there is provided an adjustable damper-type exercising device designed for use in the conventional application of two-handed expander as apparent from Figs. 1 and 2 in particular, or for attachment to frames for exercising locations and/or to fixed brackets, or as the hydraulic part of elaborate exercising machines or the like.
- the simplest form of the invention will be clear from the embodiment illustrated second and shown in Figs. 7 and 8 where the elongate frame is indicated generally by the numeral 10 and houses a longitudinal hydraulic main cylinder 13 which in this construction forms part of the frame 10.
- the frame 10 in this instance has a fixed mounting end 11 and a movable or handle end section or assembly 12.
- the longitudinal main cylinder 13 defines a main chamber 14 to be filled with hydraulic oil as the necessary non-compressible liquid which is constrained to move only within the chamber 14.
- the end of the main cylinder 13 opposite the mounting end 11 has sealing means through which a hollow tubular plunger rod 15 is sealably slidable axially of the cylinder 13, being connected at its inner end to a main piston 18 which is able to be moved by the plunger rod 15 in sealably slidable manner to define two opposite sides of the main cylinder 13 at opposite ends of the main chamber 14.
- the main piston 18 comprises two piston members 16 and 17 which in this case are of disc-like form having machined faces in tight but relatively rotational contact.
- the lower end of the plunger rod 15 (when considered in the disposition illustrated) is secured to the uppermost piston member 16 which constitutes a fixed piston member, while the other piston member 17 is secured to the lower extremity of an innermost control rod 19 extending through an axial bore of the fixed piston member 16 and axially upwards through the plunger rod 15.
- the piston members 16 and 17 have identical part- circumferential peripheral slots 71 which can be out of register as shown in Fig. 9A to prevent through-flow completely, or by rotating the adjustable lower piston member 17 as shown by the arrow 72 of Fig. 9B, the apertures 71 may be brought into register to desired extent to allow flow of liquid through the main piston 18 at desired rate.
- the free end of the plunger rod 15 (which is the upper end as illustrated) extends through any suitable sealing means comprising both air and oil seal members, as illustrated, within an upper sealing cap 20, and it has handle assembly members secured to its upper end as illustrated at 21. It will be seen from Fig. 8 that the handle end may be moved to withdraw the plunger rod 15 or subsequently retract it, various pressures being experienced as resistance to movement of the piston during such movements, with different resistances according to the degree of register of the apertures 71 through the faces of the piston members 16 and 17 of the main piston 18 as the latter is moved at the inner end of the plunger rod 15.
- the end of the main cylinder 13 opposite the sealing cap 20 connects via a connector vessel 73 with the lower open end of a displacement cylinder 22 mounted in spaced parallel relationship to the main cylinder 13 but of lesser diameter as illustrated.
- a displacement cylinder 22 mounted in spaced parallel relationship to the main cylinder 13 but of lesser diameter as illustrated.
- oil will be displaced up the displacement cylinder 22 against a movable closure piston 23 mounted in sealably slidable manner, the piston 23 being biassed in this instance by spring loading in the form of a spring 24 held by retainer cap 74 arranged to urge the closure piston normally in the direction towards the connector vessel 73.
- the vacuum normally created is offset by oil moving back to the lower end of the main cylinder 13 under the pressure of the spring 24, ensuring that there is maintained a liquid-filled condition of the main cylinder 13 at all times regardless of the positions occupied by the main piston 18 and the plunger rod 15.
- Adjustment of the adjustable piston member 17 of the main piston 18 can be made from outside the apparatus and main chamber 14 by means of a dial 25 at the handle 21 permitting rotation of the control rod 19 which causes rotation of the adjustable member 17 relative to the fixed piston member 16.
- This adjustment at the dial 25 allows a desired flow of oil to pass through the main piston 18, resulting in pressure against movement of the plunger rod 15 in and out, with the amount of resisting pressure depending upon the size of the adjustable aperture means 71 through which the oil is forced. It will be noted that the resistance will remain constant through the full stroke in or out, and it works against the viscosity of the oil, and not through pressure of oil.
- the invention provides a system which is sealed with respect to the outer atmosphere, the inner spaces being filled with a non-compressible liquid which is displaced in either direction by the main piston through apertures in the main piston from one side of the main cylinder to the other on opposite sides of the main piston, while the force to be overcome in moving the main piston arises from controlled throttling of the non-compressible liquid when the latter is set into motion by the piston for passage through the apertures in the piston.
- the frame 10a is elongated to extend between a fixed mounting end 11a and a movable end 12a, there being a main cylinder 13a. defining a main chamber 14a to be filled with hydraulic oil. Axially within the main cylinder 13a . is a hollow plunger rod 15a.
- the adjustable piston member 17a has a series of cylindrical apertures 72 arranged on an arc traced out about its axis but inwardly of its periphery. These increase progressively in diameter and may communicate according to the degree of rotation with larger equally-spaced openings 73 partway through the upper fixed member 16a and leading from an extended arcuate slot 74 for ease of flow.
- alternative design details may be easily devised for the nature of the apertures of the two piston members and the methods whereby these are secured in relative rotatable manner to the plunger rod on the one hand and to the control rod on the other hand.
- the upper end of the plunger rod 15a extends through air and oil seal members held within an upper cap assembly 20a . and it has handle assembly members secured to its upper end as indicated at 21a.
- a varied pressure resistance is felt at the handle end 21a as the plunger rod 15a is moved thereby in and out of the chamber 14a, the different resistances being caused by changing the degree of rotation of the apertures, such as the apertures 72, through the piston members 16a and 17a. of the piston 18a. which is movable with the end of the plunger rod 15a.
- oil is displaced from and to a displacement cylinder 22a, the free end of which has a closure piston 23a arranged to follow the plunger rod 15a as later described.
- a freely rotatable pulley 29 at the free outer end of the guide rod 24a Passing round the pulley 29 is a flexible wire or inextensible cable 30 which has one end affixed at 31 to the displacement cylinder 22a while its other end is affixed at 32 relative to the plunger rod 15a . through its outer handle end 12a. Because of the pulley action, the long stroke of the plunger rod 15a is accompanied by a small proportional movement of the guide rod 24a . - suitably one-half or similar predetermined relationship according to the relative diameters of the cylinders.
- the dimensions are chosen so that the closure piston 23a. is in position to ensure that the oil volume is properly contained at the correct pressure while the flexible wire or cable 30 is both effective and taut at all times, with withdrawal of the plunger rod 15a . causing movement of the closure piston 23a towards that end of the displacement cylinder which communicates with the main cylinder.
- the withdrawn displacement section of the plunger rod 15a. has a total volume equal to the displacement volume in the displacement cylinder 22a. through resultant movement of the guide rod 24a. for the closure piston 23a.
- the adjustable piston member or plate or disc 17a. of the piston 18a . is rotated by the dial 25a., and to ensure efficiency 0-rings 41 and 42 can be provided around the piston members 16a . and 17a., as illustrated, allowing for sealing on axial sliding and turning of the movable piston member, but without the piston 18a. binding against the wall of the chamber 14a.
- the upper and lower sealing rings 34 and 35 are effective as an oil-leak seal, while the lower one is principally an air-stop seal.
- a further O-ring (not shown) is provided about the control rod 19a. to ensure sealing at its end adjacent the dial 25a.
- Figs. 1 to 6 The same general principles, together with further features, are illustrated in the refined embodiment of the invention shown in Figs. 1 to 6, in which similar parts are given the same numerals as before followed by the letter "b" .
- This is set up as a two-handed manual form in which the frame 10b has at its end 12b a handle 21b fitted with a dial 25b, the other end lib also being provided with a similar handle 43.
- the two handles 21b and 43 are secured to respective mechanism housings 44 and 45 which are slidable telescopically as the plunger rod 15b is moved in and out.
- main cylinder 13b, plunger rod 15b, displacement cylinder 22b, closure piston 23b and guide rod 24b are the same as in Figs. 10 and 11, except that the pulley and cable arrangements have been changed so that withdrawal of the plunger rod 15b positively and instantly draws the closure piston 23b in the same direction which is towards that end of the displacement cylinder 22b communicating with the main cylinder 13b, while return movement of the plunger rod 15b positively and instantly draws the closure piston 23b in the opposite direction.
- the said downward run 54 of the cable 52 extends down to and around another pulley 58 on the free end of the guide rod 24b (about the same axis as that of the pulley 57) and then upwards to have its end secured at 59 to the top cap 20b.
- the cable sections themselves are omitted from Figs. 3 and 4 for the sake of clarity but are shown diagrammatically in Figs. 5 and 6, where the cable 52 has its upward run 53 shown in full outline and its downward run 54 shown in dotted outline.
- the connection at 51 is the equivalent of a clamping arrangement for a continuous run so that the effective cable length remains continuous and taut at all times.
- this type of cable arrangement is to overcome possible disadvantages of the other embodiments of Figs. 7 and 8 and Figs. 10 and 11 so far as possible air- entry to the cylinders 13b and 22b might occur as a result of prolonged use. If air should enter, oil would be displaced resulting in less movement; the oil would became aerated resulting in movement which could be unsmooth, erratic or jerky, or even noisy; while additionally any air present would be subject to temperature change which might result in expanding air pushing some oil out, whereafter more air could be sucked in when the conditions cool. In such a case, the oil seals which are designed to keep the oil in would allow air to be sucked in past the oil seals when the air shrinks again.
- the plunger-follower rod 50 is replaced by a follower rack 60 parallel to the plunger rod 15c and movable therewith in spaced parallel relationship.
- the guide rod 24c. for the closure piston 23c. has its free end coupled to a follower rack 61, the two follower racks 60 and 61 meshing with two pinions 62 and 63 secured rigidly on a common axis of rotation on the frame adjacent the cap 2 ⁇ £ to rotate freely but in unison.
