  • US 7,981,015 shows a yet further similar leg stretching device.
  • Another leg stretching apparatus is shown in US 7,294,100 which relies on a track member and sliding platforms.
  • Another device that provides only one area of stretching is shown in US 6,468,192 which stretches the spine only.
  • stretching apparatus One problem with some existing stretching apparatus, such as those discussed above, is their lack of flexibility in that many stretching devices stretch only a few muscle groups. Ropes and restraints can be used for stretching, but these are also limited in their usefulness.
  • There are a number of types of apparatus that can be used for multiple different types of stretching such as stretching frames which are typically large tubular metal structures, and stretching stations which allow for the stretching of multiple muscle groups.
  • stretching apparatus particularly stretching stations, is the size of the apparatus and this is a particular problem in locations where space for equipment may be limited, such as in gyms. Examples of large non-portable stretching machines include US 5,277,681 and US 7,563,207,
  • a portable stretching apparatus comprising: a central support frame, the frame typically defining a top and legs extending from the top towards a relatively wider base, the legs forming part of the sides of the frame, and wherein the sides of the frame may preferably be folded towards each other, for transport or storage of the apparatus; a seat fixed on the top of the support frame which seat is arranged to be used by a person seated on the seat while seated in an upright position, hand grips which are provided on either side of the seat which may be grasped by a person using the stretching apparatus while in a seated position; first and second support arms pivotally mounted to opposite sides of the top of the central support frame; wherein the first arm is adapted to be fixed in a plurality of angular orientations with respect to the top of the frame; and wherein the angular position of the second arm with respect to the top of the frame is substantially continuously variable about an arc; at least one control means for moving the angular position of the second arm while the person is seated
  • the adjustability of the pivoted supports allows one to use the equipment in a number of different positions including seated facing forwards; seated facing sideways; laying down, both supine and prone.
  • Many different stretching exercises can be performed depending on the orientation of the two adjustable supports.
  • One support is predominantly used for raising and lowering limbs to be manipulated through the stretching actions.
  • the other is predominantly used to support the user in the seated position, supine and prone positions.
  • the supports can also be used to support one or both legs in a side split or front split movement.
  • the second arm defines a longitudinal axis and is telescopically adjustable in length along that longitudinal axis.
  • the second arm defines an end element in the form of a padded end restraint which extends to one side of the longitudinal axis of the arm in a direction which is perpendicular to the longitudinal axis of the second arm.
  • the padded end restraint may be pivotally mounted to the end of the second arm and may be rotated about the pivot and fixed to either side of the second arm.
  • the apparatus may include a ratchet mechanism controlling the position of the second arm and wherein the control means for moving the position of the second arm is a lever positioned adjacent the grips at the top of the frame.
  • the hand grips comprise arcuate rings and the lever is pivoted about the centre of one of the arcuate rings and its position relative to the ring serves as an indicator of the position of the second arm.
  • the first support arm is pivotally mounted on a stub element which projects from the top of the apparatus.
  • the first support arm may comprises two parallel elongate members, each parallel elongate members being pivotally mounted to a stud member and linked by a padded crosspiece.
  • the two parallel elongate members are telescopically extendible.
  • the foot restraint comprises a padded bar or brace fixed to a side of the frame.
  • the position of the padded bars on the sides of the frame may be adjustable.
  • the frame has an inverted V-shaped in use and includes a foldable crosspiece bracing the frame.
  • the apparatus may be folded with the adjustable supports generally parallel to the legs of the support frame when not in use so, that the apparatus occupies minimum space. In this position the compact apparatus is small enough to fit into a car boot or airline overhead locker and may be easily carried and transported or stored at home. In a gym several devices may be stacked one on top of another to reduce the floor space required for the apparatus.
  • the supports of the apparatus are adjusted so that they are at the correct orientation for the desired stretching exercise. They can be used to support the torso or leg or legs of the body depending on the particular stretching exercise being undertaken.
  • the pivoted support arms may be used dynamically (moving) or fixed. Mechanisms may be provided to fix the supports in a particular position, using spring and ratchet system or a hydraulic cylinder or the like.

  • the apparatus includes a central support frame 12 in the shape of an inverted V, and a cushioned seat 14 on the top 13 of the support frame.
  • First and second support members/arms 16 and 18 respectively are mounted to the top of the frame 12 on opposite sides of the frame and extend generally away from the support frame.
  • the support frame includes a generally rectangular top portion/frame 20 on top of which the seat 14 is mounted.
  • Two legs 22, 24 are pivotally mounted to one side of the top of the frame.
  • a further pair of legs 26, 28 are pivotally mounted to the opposite side of the top of the frame.
  • a first foot restraint 30 or support pad in the form of a bar covered in tubular padding extends between the legs 22 and 24, close to the feet of those legs.
  • a second foot restraint 32 also in the form of a bar covered in tubular padding extends between the legs 26 and 28, close to the feet of those legs.
  • a bracing element 34 extends between legs 22 and 26 and a second bracing element 36 extends between legs 24 and 28.
  • Each bracing element 34, 36 includes a central pivot 38 which allows the brace 34, 36 to be folded to allow the legs to be pivoted towards each other for storage or transport of the apparatus 10.
  • a semi-circular ring 50, 52 is defined at each side of the top of the support frame. These rings can be gripped by the hands of a person stretching on the apparatus, in use.
  • two short tubular stub members 60, 62 extend away from the top of the support frame.
  • the first support member 16 is pivotally mounted to the distal ends of the stub members 60, 62.
  • the first support member 16 comprises a first elongate tubular member 64 which is pivoted to the distal end of stub 60, a second elongate tubular member 66 which is pivoted to the distal end of stub 62 and a crosspiece 68 which extends between the distal ends of the tubular members and is covered in a padded tubular support 70.
  • the first support member may be pivoted about the distal ends of the stub members into different fixed positions such as lowered when not required or for storage, as shown in Figure 1, oriented generally vertically as a lower back support as shown in Figure 4 or in angled or horizontal positions as shown in Figures 2 and 3.
  • the tubular elements 64 and 66 are telescopic so that the length of the first support member and the distance of the crosspiece 68 from the stubs 60 and 62 may be adjusted.
  • a further elongate tubular element 70 which forms part of the second support arm/member 18 is pivotally mounted to the top of the frame as is best seen in Figure 3.
  • the tubular element is telescopic and may be extended and retracted.
  • Figure 3 shows that the tubular element 70 defines an outer tube 72 and an inner tube 74 which slides in the outer tube and which defines a series of apertures 76 for receiving a locking pin 78 to adjust the length of the tubular element 70.
  • the outer tube 72 is enclosed by a cylindrical pad 80.
  • a cylindrical pad 74 locates over the side tube 72.
  • the side tube may be rotated in an arc about the longitudinal axis of the tubular element 70.
  • the seat 14 defines a cut out or aperture 90 which allows the second support arm 18 to rotate upward until it is nearly vertical.
  • the second support arm 18 is mounted to a movable arm 91 which is mounted about a pivot axis 93 and can be rotated by handle 100, which is located adjacent the ring/grip 52, via connecting rods 94, 96. When the handle 100 turns through a particular angle, the arms 91 and 18 move through the same angle.
  • a fixed toothed ratchet type wheel 92 is fixed to the frame
  • a spring biased pawl or ratchet block 102 is mounted to the arm 9 land prevents the support arm 18 from moving when engaged with the toothed wheel 92 as shown in Figure 9.
  • the support arm 18 may thus be moved by simply moving the handle 100 while the stretching apparatus is in use. When the handle is released the pawl 102 re-engages in the ratchet wheel.
  • a person can use the apparatus in a number of different positions, as shown including seated facing forwards; seated facing sideways; lying down both prone and supine; standing; and suspended with the front of the thighs on the seat and the legs hooked under one moving arm, while doing a traction movement.
  • the equipment is designed to allow isometric (muscle not changing length) contractions throughout a number of positions throughout the range of motion and muscle lengths. This strengthens the muscle throughout the muscle length and importantly increases the strength of the muscle at the longest muscle length and end of motion. This greatly decreases the risk of muscle injury and increases the total amount of muscle force generated over the entire range of motion and muscle length
  • the apparatus also allows for prolonged static stretching without causing bending of the lumbar or thoracic vertebrae in the back. Static stretching has been shown through research to be less than effective if the stretch is held for only 15 to 20 seconds.
  • the machine allows the user to hold stretches for extended periods which allows for muscle fibre and tenderness elongation.
  • During traditional stretching to maintain tension on the muscle that will cause elongation requires the user to bend at the waist which causes improper strain on the vertebrae in the back. Also this compressed position impacts on the stomach and lungs which causes discomfort.
  • The may also enable the user to perform PNF stretching.
  • This type of stretching is highly effective in requires the leg to be moved to, and halted at, a number of positions throughout the range of motion and muscle length. At each of these positions and isometric contractions will be performed against the support of the device.
  • the apparatus allows for this PNF stretching to be performed on a large range of muscles in the body, including hamstrings, hip flexors, iliopsoas, gluteal, long adductors, short adductors, transverse adductors etc.
  • the apparatus also allows a user to perform eccentric stretching and strengthening which the user resists against the raising mechanism of the apparatus thereby contracting the muscles while they are lengthening.
  • the apparatus also allows the user to identify the differences in range of Motion from left to right side of the body. This is an important consideration as the differences are indicated to be prevalent in the development of back pain through the misalignment of the pelvis, and viscoelastic tension on the posture of the user. By identifying these differences, a plan can be put in pace that will correct these differences and in the long term assist in eh resolution of back pain and sciatica suffering.
  • the apparatus also allows for the identification of muscle imbalances.
  • Various type of stretches that may be carried out are shown in Figures 5 to 7.
  • Figure 5b illustrates a gluteal stretch
  • Figure 5c a long adductors stretch
  • Figure 5d an short adductors stretch
  • Figure 5e and inversion traction
  • Figure 5f advanced front splits
  • Figure 5g an assisted calf stretch (downward dog).
  • Figure 6a illustrates a standing soleus stretch
  • Figure 6b shows a hamstring gluteal stretch
  • Figure 6c shows assisted push ups
  • Figure 6d shows a front deltoid pectoral stretch
  • Figure 6e shows a standing gluteal stretch.
  • Figure 7a shows s front or side splits
  • Figure 7b shows a standing quadriceps stretch
  • Figure 7c shows a hamstring hip flexor
  • Figure 7d shows a seated hamstring hip flexor
  • Figure 7e shows a standing hamstring hip flexor
  • Figure 7f shows an advanced long adductors stretch
  • Figure 7f shows a beginners long adductors stretch.
  • the apparatus embodying the invention may give the user the benefit of stretching a large number of muscle groups in a device that is portable, foldable and easily transportable.
  • the device also allows the user to perform stretches without the need to flex their back to increase tension and induce stretch in the lower limbs.
  • the apparatus also allows the user to perform isometric contractions which both increase the strength of the muscles being targeted and decreased the impact of the stretch H reflex allowing deeper stretch with less discomfort. This function also realigns the myofascia of the muscles, which is currently addressed by either massage or the use of foam rollers.
  • the apparatus also, through the inventive positioning of foot restraints and the second swing arm, provides the user to perform contralateral stretches to the two separate muscle groups that are engaged in a person's stride. This is important in the rehabilitation of muscle strains and increases athletic performance through increases stride length and the increased muscle stretch at the end range of motion through the use of isometric contractions.
  • the apparatus also allows the user to change the position of the support arms without having to dismount from the apparatus. This allows for continuous use of the machine for numerous different muscle groups in a continuous operation.
  • both the first and second support arms could be operated by the lever and ratchet mechanism as the second support arm.
  • the lever on one side of the seat will move one arm and the lever on the opposite side of the seat will move the other arm.

Abstract

La présente invention concerne un appareil d'étirement portable (10) qui comprend un cadre de support central (12), le cadre définissant une partie supérieure et des pieds (22, 24, 26, 28) s'étendant de la partie supérieure vers une base relativement plus large, les pieds formant une partie des côtés du cadre. Les côtés du cadre peuvent, de préférence, être repliés les uns vers les autres, pour le transport ou le stockage. Un siège (14) est fixé sur la partie supérieure du cadre de support et le siège est adapté pour être utilisé par une personne assise sur le siège dans une position verticale. Des premier et deuxième bras de support (16, 18) sont montés de façon pivotante sur les côtés opposés de la partie supérieure du cadre de support central. Le premier bras est adapté pour être fixé dans une pluralité d'orientations angulaires fixes par rapport au cadre. La position angulaire du deuxième bras (18) est sensiblement variable de façon continue autour d'un arc. Des poignées (50, 52) sont disposées de chaque côté du siège et peuvent être saisies par une personne utilisant l'appareil d'étirement en position assise. Au moins un moyen de commande est disposé pour déplacer la position angulaire du deuxième bras par un utilisateur lorsqu'il est assis ou allongé sur l'appareil. L'appareil comprend au moins un moyen pour retenir ou bloquer une jambe d'un utilisateur sur un côté, et de préférence sur les deux côtés du cadre.
