Abstract

A swim-in-place trainer having flow assist features incorporated into the pool design. The flow assist features may include a contoured bottom having a flow directional hump located in approximately the center of the swim area. The flow directional hump may extend laterally across the entire swim area and separate a deeper front portion of the pool from a shallower rear portion of the pool. Other flow assist features may include a front and rear ridge for directing water to and from the swim area, respectively. Interior side walls disposed on opposing sides of the swim area may each include an inner front portion for creating a flow improving vortex to reduce water friction. An optional propulsion means, such as a pump or impeller, may provide a variable water flow dependent upon the location of a swimmer in the swim area or other factors.

Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Application No. 60/535,417, filed on Jan. 9, 2004, which is hereby incorporated by reference herein in its entirety, including but not limited to those portions that specifically appear hereinafter, the incorporation by reference being made with the following exception: In the event that any portion of the above-referenced provisional application is inconsistent with this application, this application supercedes said above-referenced provisional application.
  • STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
  • NONE.
  • BACKGROUND
  • 1. The Field of the Invention
  • The present disclosure relates generally to swimming pools, and more particularly, but not necessarily entirely, to swim-in-place training pools.
  • 2. Description of Related Art
  • Swim-in-place pools allow a swimmer to engage in swimming, particularly aerobic swimming, without the need for a full-sized pool. Swim-in-place pools are advantageous over full-sized pools due to their reduced footprint, reduced water requirement, and lower installation and operating costs. Swim-in-place pools can be used for, among other things, exercise, training, and therapy. In the past, a swim-in-place pool typically comprised a small pool where one or more circulating means is used to circulate the water to simulate the swimmer moving forward in the water as the swimmer swims. Using a tether to simply hold a swimmer in place without a means to circulate the water has proven to be inadequately effective.
  • U.S. Pat. No. 2,035,835 (granted Mar. 31, 1936 to Raber) discloses a swim-in-place pool comprising a false bottom forming a chamber between a swimming area and the actual bottom of the pool. Housed in the chamber are one or more propellers used to circulate the water around the false bottom. The '835 patent also discloses a pool having a quadrangular shape and rounded corners. Two partition walls running parallel to the sides of the pool define a swim area and two circulating loops. Driving propellers are disposed between the partition walls and the pool sides in order to circulate the water through the swim area.
  • U.S. Pat. No. 2,875,528 (granted Mar. 3, 1959 to Garate) discloses a swim-in-place pool comprising a generally rectangular tank having a post with a U-shaped saddle for supporting the swimmer in the proper swimming position. Strategically placed mirrors are also located on the bottom of the tank to thereby allow a swimmer to observe and make corrections to the swimmer's stroke. No water circulation means is provided.
  • U.S. Pat. No. 3,534,413 (granted Nov. 6, 1967 to Plasseraud) discloses a swim-in-place pool having one or more water jets to circulate the water. Each of the water jets has an adjustable nozzle whereby the swimmer can move against the repelling action of the jets while performing swimming motions. The water jets are driven by electric pumps.
  • U.S. Pat. No. 4,001,899 (granted Jan. 11, 1977 to Mathis) discloses a combined swim-in-place pool and spa. A vertical divider is removably mounted between the spa area and the swim-in-place area to thereby allow separate heating of each area. Water jets are directed such that a user can swim in a substantially stationary position against the force of the water jets.
  • U.S. Pat. No. 4,577,859 (granted Mar. 25, 1986 to Gossett) discloses a swim-in-place pool with a restraining assembly to maintain a swimmer in place in the pool while swimming. The restraining assembly is configured to allow the swimmer to roll back and forth relatively freely while swimming.
  • U.S. Pat. Nos. 5,027,449 and 5,058,219 (granted Jul. 2, 1991 and Oct. 22, 1991, respectively, to Teratsuji et al.) disclose a swim-in-place pool having a curved front leading to a lower water return passage. The pool includes guide vanes to channel the water into and out of the lower water return passage. An impeller located in the lower passage circulates the water through the swim area.
  • U.S. Pat. No. 5,044,021 (granted Sep. 3, 1991 to Murdock) discloses a swim-in-place pool that comprises a swim area having two opposing side walls and a plurality of turning vanes in the return water paths. The turning vanes at the rear of the swim area direct the water into the return channels while the turning vanes at the front of the swim area direct the water into the main swim area. Dual impellers, one in each return channel, operate to circulate the water around the pool.
  • U.S. Pat. No. 5,315,720 (granted May 31, 1994 to Lior) discloses a swim-in-place pool that comprises an inner horizontal waterway and an outer circulating waterway. A plurality of impeller blades are advanced in unison through the outer waterway to thereby provide a constant flow of water through the swim area.
  • U.S. Pat. No. 5,787,519 (granted Aug. 4, 1998 to Smith) discloses a free-standing swim-in-place pool that includes a gutter for catching and retaining water that spills over the lip of the pool. The water from the gutter is emptied into drain pipes leading to a pump which recirculates the water back into the pool. Baffles located deep within the pool absorb waves caused by the swimming motion of a user.
  • In the previously available devices, there is also known a device as the Endless Pool®. This device includes a propulsion assembly that propels water against a swimmer. The propulsion assembly may be adjusted as needed to increase or decrease the strength of the flow current. Water return channels are located underneath benches aligned along the sidewalls of the pool. This device may also be used as a trainer and a hot-tub spa.
  • Another previously available device is known as the Swim Spa™. This device may also double as both a swim-in-place pool and a spa. This device includes swim jets to provide a water flow against a swimmer.
  • Each of the previously available apparatuses disclosed above has a distinct disadvantage due to either a lack of flow inducing features, or an inefficiency of flow inducing features incorporated into the design of the pools. First, in the above described devices, the circulating water does not correctly simulate real water flow as would be experienced by a swimmer swimming in a large body of water. The water flow is often turbulent or unnatural, which is discomforting to a swimmer. Next, the mechanical devices require a significant amount of energy in order to circulate the water. Finally, if users desire to use the swim-in-place pool as both a trainer and a hot-tub spa, they must repeatedly heat and cool the water to enable the cooler temperature for a workout, and the warmer temperature for hot-tub spa use.
  • The prior art is thus characterized by several disadvantages that are addressed by the present disclosure. The present disclosure minimizes, and in some aspects eliminates, the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.
  • The features and advantages of the disclosure will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the disclosure without undue experimentation. The features and advantages of the disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

  • DETAILED DESCRIPTION
  • For the purposes of promoting an understanding of the principles in accordance with the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the disclosure as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the disclosure claimed.
  • It must be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. In describing and claiming the present disclosure, the following terminology will be used in accordance with the definitions set out below.
  • As used herein, the terms “comprising,” “including,” “containing,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.
  • Applicant has discovered, inter alia, a swim-in-place trainer that utilizes a pool having flow directing features incorporated into its design to thereby improve water circulation and reduce water turbulence. The flow directing features reduce and in some cases eliminate the need for mechanical water propulsion devices. The flow directing features channel water displaced by a swimmer to circulate more evenly to create a swimming environment that feels more natural to the swimmer. Another aspect of the present disclosure includes a swim-in-place trainer that incorporates adjustable flow directing features to thereby control the water flow for any particular swimmer or condition. These and other features of the present disclosure will be further addressed below.
  • Referring now to FIG. 1, there is shown a swim-in-place trainer 20 pursuant to one embodiment of the present disclosure. The swim trainer 20 comprises a pool 22 of sufficient size to accommodate a user 50 to swim-in-place. The pool 22 may be free standing as shown if FIG. 1 for above ground installation or the pool 22 may also be installed in ground (not shown) as is well known in the art to thereby allow installation in almost any setting. When free standing, the pool 22 may be housed in a support structure 24 such as those structures utilized for free standing hot tubs and spas and the like. The support structure 24 for the pool 22 may comprise an access door 26 to allow access to any internal workings, such as pumps, motors, filters and heating systems.
  • The swim trainer 20 may be optionally disposed next to a detachable spa section 28. It will be appreciated that the separation of the swim trainer 20 from the spa section 28 is advantageous due to the fact that the water in the spa section 28 and the swim trainer 20 may be maintained at different temperatures.
  • The pool 22 itself may optionally be constructed in several modular pieces, as shown in FIG. 8, or as a single unit as shown in FIG. 1. Ideally, the pool 22 is formed using molds for fiberglass or vacuum forming. The pool 22 may also be formed using more traditional pool construction materials, such as cement. The pool 22 may also be formed of metal. Thus, it will be appreciated by those skilled in the art that the pool 22 may be constructed of various materials, and is not limited to any one particular composition.
  • The pool 22 may have a filtration system (not shown) as is standard in most pools and spas. The filtration system may serve to remove debris from the pool. The pool 22 may also have a heating system (not shown) to heat the water as desired. The heating and filtration systems may be shared in common with the adjacent spa 28. As mentioned above, it should be noted that it may be preferable to maintain the water temperature in the pool 22 at a temperature lower than that in the spa 28. This is due to the fact that some people may prefer a cooler water temperature in the pool 22 while exercising as opposed to that in the spa 28. As will be explained in further detail below, the pool 22 may also include a water circulation system such as an electric motor coupled to a water pump or an impeller (not shown). A control panel 108 may be used to control any attached systems, such as the heating system or the water circulation system, if present.
  • The pool 22 may comprise a swim area through which water may flow from a front portion 34 of the swim area to a rear portion 36 of the swim area. The swim area may be further defined by a pair of flow directing walls 38 disposed on either side of the swim area. The flow directing walls 38 may extend in an upward direction from the bottom of the pool 22 to a height sufficient to be near to or exceed the expected water level in the pool 22. The flow directing walls 38 may also extend in a longitudinal direction from about the front portion 34 of the pool 22 to about the rear portion 36 of the pool 22.
  • The flow directing walls 38 may be permanently affixed as shown in FIG. 1 or, as shown in FIG. 6 and 6A, the flow directing walls 38A may be removably attached to the bottom of a swim-in-place trainer 20A or to a cross member across the top of the pool. In FIG. 6, the flow directing walls 38A may each comprise a pair of downwardly extending posts 40. The posts 40 may be received into one of a set of front holes 42 and one of a set of rear holes 44. The front set of holes 42 and the rear set holes 44 are arranged such that the width between the flow directing walls 38A may be varied. In addition, the front holes 42 and the rear holes 44 may allow the flow directing walls 38A to be adjusted forward or rearwards in relation to the swim area.
  • The front set of holes 42 and the rear set of holes 44 may also allow the flow directing walls 38A to be positioned in a non-parallel orientation with respect to each other. The flow directing walls 38A may also be interchangeable with other flow directing walls of different sizes and shapes. The removable flow directing walls 38A may also allow the swim trainer 20A to be used as both a swim trainer and a spa. When configured as a swim trainer, the flow directing walls 38A may be installed, and when in the spa configuration, the walls 38A may be removed.
  • Referring now back to FIG. 1, a tether 46 and tether support 48 may be used to maintain the user 50 in the swim area while the user 50 is swimming. It will be appreciated that the tether 46 and the tether support 48 constitute one type of restraint device. One end of the tether 46 may be attached to the user 50 or to a harness 52 worn by the user 50. The other end of the tether 46 may be attached to the tether support 48. The length of the tether 46 may be adjustable. Also, the tether 46 may optionally comprise a load sensor 54, the function of which will be described in detail further below.
  • FIG. 5 illustrates the tether support 48 in more detail. The tether support 48 includes a pair of vertical members 58 spanned by a cross bar 60. A lower portion of each of the vertical members 58 may be pivotally mounted on a shaft 66 extending through both a vertical plate 64 and the vertical member 58. The pivotal mount of each of the vertical members 58 allows the tether support 48 to be angularly adjusted. Pins 68 may be inserted into holes 70 on each of the vertical plates 64 and through a hole 72 in each of the vertical members 58 to thereby lock the tether support 48 at discrete angles. The overall height of the cross bar 60 may also be increased or decreased by adjusting the individual height of each of the vertical members 58. The width of the cross bar 60 may also be varied. One method of accomplishing the above is to construct the vertical members 58 and the cross bar 60 such that they are telescopically adjustable as is known by those skilled in the art.
  • The tether support 48 may also be adjusted forward or rearward with respect to the swim area by the use of holes 56 located in the top of each of the flow directing walls 38 (see FIGS. 1 and 2). This may be accomplished by installing a post 62 into corresponding holes 56 located in the top of the flow directing walls 38.
  • Adjusting the tether 46 and the tether support 48 either individually or in combination may produce advantageous feature over the prior art. In particular, the pivotal attachment of the tether support 48 allows the angle between tether support 48 and the surface of the water in the pool 22 to be varied. A height adjustment of the tether support 48 may accomplish the same result. For beginning swimmers, the angle of the tether support 48 can be adjusted to provide more upward support for the swimmer. For more advanced swimmers, the angle can be adjusted and the tether 46 lengthened to provide less upward support for the swimmer. One embodiment of the present disclosure provides for the use of a flow meter to evaluate and display the estimated distance swam by the user 50.
  • Another embodiment of a tether support bar 48A is shown in FIGS. 5A and 6A. The tether support bar 48A includes a cross member 150 having a top piece 152. The cross member 150 further comprises a first set of holes 158 for mounting the cross member 150 to a swim-in-place trainer 20B using holes 160. The holes 160 may allow the cross member 150 to be adjustably positioned forward or rearward with respect to the swim area of trainer 20B. The cross member may comprise a second set of holes 156 for attaching flow directing walls 38B. The second set of holes 156 may allow the flow directing walls 38B to be laterally adjustable with respect to the swim area of trainer 20B. The top piece 152 may also comprises a third set of holes 154 for providing variable anchor points for a tether 46.
  • One of the primary benefits of the present disclosure includes the flow directional features incorporated into the design of the swim trainer 20. These flow directional features improve water flow and allow for a more natural feeling to the user 50. These flow directional features further greatly reduce and in some cases eliminate the need for a mechanical propulsion device, such as a pump or propeller. In the event that a mechanical propulsion device is employed, it will require less power because the flow directional features produce a smoother and less turbulent water flow. The flow directional features described in further detail below may be used separately or in combination with each other.
  • Referring now to FIGS. 2, 3 and 4, a flow directional hump 80 may be disposed in approximately the middle of the swim area. The flow directional hump 80 may extend laterally across the swim area from one of the flow directing walls 38 to the other flow directing walls 38. The flow directing hump 80 may separate the front portion 34 of the swim area from the rear portion 36 of the swim area as best seen in FIG. 3.
  • An apex 82 of the flow directional hump 80 is shallower than either the front portion 34 or the rear portion 36 of the pool 22. The hump 80 should not interfere with the swimming motions of the user 50 due to the fact that it should be located at about the waist of the user 50. It will also be appreciated that the front portion 34 of the pool 22 is deeper that the rear portion 36 of the pool 22. The deeper front portion 34 allows the user 50 to utilize the full range of motion of his or her arms while swimming, even when utilizing what is commonly referred to as a “front crawl” stroke and also the “butterfly” stroke. The rear portion 36, while shallower that the front portion 34, may be of sufficient depth to allow the user 50 the full range of movement of his or her legs while kicking. The motion of the user's 50 arms and legs is typically sufficient to create a current through which the user 50 may swim without the use of a mechanical propulsion device.
  • A front ridge 84 may bisect the front portion 34 of the pool 22 as seen in FIGS. 2, 3 and 4. The front ridge 84 may separate the front portion 34 into a left side and a right side. The depth of the front ridge 84 may be shallower than the depth of the left and right sides of the front portion 34, but deeper than the depth of the apex 82 of the hump 80. The front ridge 84 may extend from a front merge point 90 to about the rising slope of the hump 80. A rear ridge 92 may extend from a rear merge point 94 towards the hump 80.
  • FIG. 3A illustrates another embodiment of the present disclosure. In FIG. 3A, there is no flow directional hump separating the front and rear portions. Instead, there is a smooth transition between the front and rear portions.
  • A pair of water return channels 96 are each formed between an outer pool sidewall 98 and one of the flow directing walls 38. Each of the water return channels 96 forms a path to allow water to be returned from the rear portion 36 to the front portion 34 of the pool to thereby create a circulating current through which a user 50 may swim.
  • It should be noted that the outer pool sidewall 98 is also smoothly contoured to optimize the circulation of water. In particular, the outer pool wall 98 is rounded at the ends to direct the water appropriately into or out of one of the water return channels 96. The front ridge 84 and the rear ridge 92 may facilitate the merging or separation of the water flow, respectively.
  • The flow directing walls 38 may each comprises an inner front portion 104 and an inner rear portion 106. Referring now more particularly to FIG. 2, each inner front portion 104 may comprise an arcuate surface and taper inward to thereby narrow a water entrance 73. The inner rear portions 106 of the flow directing walls 38 extend relatively parallel to the swim area to a water exit 74.
  • Disposed within each of the water return channels may be jets 100 and inlets 101. The inlets 101 may supply a pump or impeller driven by a motor, neither explicitly shown, to create a water stream exiting through jets 100. The positioning of the inlets 101 and the jets 100 may be such to aid water circulation in the pool 22.
  • Jets 100 may comprise variable nozzles 102 and the output of the pump and motor may also be variable as will now be explained. The output of the jets 100 may be controlled by varying the nozzles 102 or the output from the motor running the pump or impeller(not shown). The swim trainer may comprise a control panel 108 and position sensors 110 as shown in FIG. 1. The position sensors 110 may include infrared, optical, laser or any other device known to those skilled in the art capable of determining the position of the user 50 in the pool 22.
  • The block diagram in FIG. 10 illustrates how the control panel 108, load sensor 54, and position sensor 110 may each control the water flow in the trainer 20. The control panel 108, load sensor 54 and position sensor 110 are all in communication with controller 112 which may control a variable speed motor 114 driving a pump or impeller 116. The controller may also control servos 118 which vary the output of nozzles 120.
  • In the case of the manual control panel 108, the user may select a flow rate or a preprogrammed routine. In the case of the load sensor 54, the water flow is determined by the load on the sensor 54. In the case of the position sensor 110, the position of the user 50 in the pool 22 determines the water flow generated by the pump 116 and/or nozzles 120. For example, in the event that the user 50 is moving rearwards in the swim area, the water flow may decrease in order to allow the user to return to an optimum position. In the event that the user 50 is moving forward in the swim area, the water flow may increase. In addition, information from the load sensor 54 may be fed to an electrical device such as a computer to record the workout. The load sensor 54, may for example, be able to measure and determine the swimmer's power.
  • As may be seen in FIG. 7, the flow lines show the flow of the water in the pool 22. As the user 50 begins swimming, the water is moved over the hump 80 and into the rear portion 36 of the pool 22. The rear ridge 92 directs the water into one of the water return channels 96. If present, the inlets 101 and jets 100 assist the flow of water through the water return channels 96 and into the front portion 34 of the pool.
  • The water enters the front portion 34 of the swim area from the water return channels 96. Some of the water from each of the water return channels 96 converges at the front merge point 90 and at the front ridge 84. These features direct the flow of water towards the swim area.
  • Small vortexes represented by the flow lines marked with the reference numeral 114 may form next to each of the inner front portions of the flow directing walls 38. These vortexes create an additional current to overcome friction losses and thereby contribute to the overall water flow. Once past the vortexes, the water then flows through the swim area and is recirculated. As best seen in FIG. 2, a rear portion 38A of each of the flow directing walls 38 may be wider than a front portion 38B of the flow directing walls 38. In one embodiment, the rear portion 38A is 50% wider than the front portion 38B.
  • The flow of the water through the swim area and around the water return channels 96 is further facilitated by a contoured bottom of the pool 22. Each water return channel 96 may be less than or equal to 50% of the width of the swim area. As shown in FIGS. 1-4, the front portion 34 of the swim area is deeper than the rear portion 36 of the swim area. The contoured bottom in the front portion 34 is further divided into two sides by the ridge 84 protruding from the bottom. These features, in conjunction with the flow directing hump 80, improve the natural flow of water in the pool 22. It will be appreciated that the contoured bottom pursuant to the present disclosure may be of any shape that improves the flow of water through the swim area.
  • In one exemplary embodiment, the pool 20 may have dimensions of 13′×10′×3′6″ (3.96 meters by 3.05 meters by 1.07 meters). The depth of the apex of the flow directional hump 80 may be about 2′ (0.60 meters) while the maximum depth of the front portion 34 and the rear portion 36 may be about 3′6″ (1.07 meters) and 2′6″ (0.76 meters), respectfully.
  • As previously mentioned, a swim trainer 20C pursuant to the present disclosure may be of modular design as shown in FIG. 8. Each of the modular pieces may include a flanged portion 130. When assembled, each of the flanged portions 130 be held together with a bolt and nut assembly. A gasket material (not shown) may be interposed between each of the flanged portions 130 to create a water tight seal.
  • In a separate embodiment shown in FIG. 9, a swim trainer 20D may comprise a removable insert module 120 that can be placed in a larger swimming pool as shown in FIG. 9. The removable insert module 120 may include weights or underwater tubes for holding the swim trainer 20D in place. Ports may allow water from the pool to enter the swim trainer 20D. The insert module 120 may also include leveling pads to level the swim trainer 20D in the pool.
