WEIGHT RA ISING EXERCISING APPARATUS Filed Jan. 26, 1951 2 Sheets-Sheet 2 A /6 \5 i i 4O F/G. 6 /7 inventor WIL LIAM HIINTER Attorney Patented Aug. 11, 1953 WEIGHT RAISING EXERCISING APPARATUS William Hunter, Edinburgh, Scotland Application January 26, 1951, Serial No. 207,903 In Great Britain February 16, 1950 12 Claims.

This invention relates to apparatus for exercising the limbs of the body by the active efforts of the operator against a resistance which commences from zero and increases to a maximum as the effort is increased, and in which the resistance is produced by the raising of a weight or weights.

The apparatus of the present invention comprises an upright frame structure supporting a series of pulleys on fixed axles, a movable weight suspended from a rope (which term is to be understood as including a belt or flexible cable) passed around the pulleys, an elongated base or platform, to the rear end of which said upright frame structure is secured, a guide pulley at the junction of said upright frame structure with said base or platform, said rope being passed around said guide pulley to provide a straight substantially vertical rope section and a straight substantially horizontal rope section, and a pulley block carrying a jockey pulley engaged with one of said rope sections and engageable with either of them, said pulley block being adapted for attachment to the person and to be movable to deflect the rope section with which it is engaged, the pull required to deflect the rope section increasing from zero to a maximum determined by the mass of the weight.

The rope may be anchored at both ends or it may be anchored at one end, or the rope may be endless. Where the rope is endless, the weight is suspended from the rope between a pair of fixed pulleys around which the rope passes. When the rope is anchored at one end, the weight is suspended from the other end of the rope. Where the rope is anchored at both ends, the weight may be suspended from the rope either between a pair of fixed pulleys around which the rope passes, or between one end of the rope and a succeeding fixed pulley around which the rope passes.

In order that the invention may be more clearly understood reference is hereinafter made to the accompanying drawings in which:

Figure l is a perspective view of one form of the apparatus, parts being broken away to facilitate illustration.

Fig. 5 is a diagrammatic view illustrating how the apparatus shown in Fig. 1 can be used.

view of the jockey Fig. 6 is a similar view to Fig. 5 showing another way in which the apparatus illustrated in Fig. 1 can be used. I

Figs. 7 and 8 are diagrammatic views illustrating simpler embodiments of the invention.

In Fig. 1 of the drawings, a base frame is constituted by a pair of spaced longitudinal horizontal frame members I 0 connected together at their front and rear ends by transverse support members II. The frame members H1 at their rear ends support four spaced vertical tubular or solid posts I2 rigidly connected together by web plates I3 and a top plate Hi to form an upright frame.

The structure comprising the base frame and upright frame supports a series of pulleys I549 mounted on fixed axles 20, namely a lower front pulley [5, a guide pulley I 6 at the junction of the base frame with the upright frame, a lower rear pulley ii, an upper front pulley l8 and an upper rear pulley l9. A movable weight support 2| is vertically slidable on the posts l2 and is suspended from a movable pulley 22 connected to the weight support 2| by means of a rod 24. A rope, belt or flexible cable 25 (shown in chain-dotted lines in Fig. 1) is passed around the fixed pulleys I 5, l6, l1, l8 and I9 and around the movable pulley 22. The ends of the rope 25 may be connnected together by means of a hook and eye fastening 26, or by any other suitable releasable fastening means. A jockey pulley 21 (Fig. 3) is engaged with the rope 25, the pulley 21 being rotatable in a provided with an eye member 28 for a purpose hereinafter stated.

A seat may be provided for the operator or patient. By way of example, a seat 34 is shown in Fig. 1 supported on rods 30 having lower extensions adjustably secured by bolts 33 to the front transverse support member II. The seat 34 may have a thigh support 3|. Any other form of seat may be provided.

The apparatus above described may be used in a number of ways for exercising any part of the body. For leg, ankle or stump exercises, the patient may be seated on the seat 34 which may be adjusted for height to suit the patients physique. As indicated in Fig. 5, the leg or stump to be exercised is harnessed to the pulley block 29 and the patient is encouraged to move the limb against the resistance of a weight 40 supported on the Weight support 2!. The pulley block 29 may be harnessed to any part of the person, and any convenient means may be used for attaching the pulley block to the part of the person to be exercised. For example,

pulley block. 29'

as shown in Fig. 4 a strap 32 having cross straps 35 and 36 may be strapped to the foot of the patient, the strap 32 having a hook or clip 31 which can be engaged with the eye member 25 of the pulley block.

As shown in Fig. 6, the pulley block 29 is engaged with the vertical section A of the rope 25 which extends between the upper and lower pulleys l8 and IE, but it may be engaged with the vertical rope section C. If desired, the hook and eye fastening 26 may be disconnected and the rope 25 anchored at its ends as at 3B in Fig. 8, or the ends of the rope may be anchored to any convenient fixed parts of the machine. It will be understood that Various weights 40 may be supported on the weight support 21.

On reference to Fig. 7 it will be seen that the apparatus may be simplified by suspending the weight 4|! from one end of the rope 25, which passes over fixed pulleys 49, 5E! and guide pulley 16 to a point 5! at which the other end of the the rope passing down and [6 so that the rope forms at and a horizontal secrope is anchored, around the pulley least a vertical section A tion B. The pulley block 29 can be engaged with the section B as in Fig. '7 and as in Figs. 5 and 8. Alternatively by passing the pulley block 29 between the rope and the pulley 16, the pulley block 29 can be slid along the rope and engaged with the vertical rope section A as indicated in It will be observed that in all cases, the aim of the patient is to deflect the rope section from its straight form, the pulley It being free to ride along the rope section A or B. The force required to deflect the rope gradually increases from zero to a maximum determined by the load imposed by the weight 40. Instead of the pulley block 29 being engaged with the vertical rope section A in Fig. 6, it may be engaged with the rear'vertical rope section C.

Although I have shown the foot of a patient harnessed to the pulley block 29, it must be understood that any of the limbs of the patient or the trunk, neck, shoulders or head of the patient may be harnessed to the pulley block. The construction of harness employed will vary according to the part of the body to be exercised.

By seating the patient as in Fig. 5 but with the lower part of his leg fastened against movement, for example, by fastening the lower part of. the patients leg to the seat frame so that he can only movehis ankle and attaching his foot to the pulley block 29, the patient can exercise hisankle;

Fig. 6 shows the apparatus in use for hip joint exercises. If the patient is seated instead of standing as in Fig. 6, the muscles controlling fiexion of the knee joint maybe exercised. Moreover, if the patient turns sideways from the frontal position shown in Fig. 6, the adductor muscles may be exercised by attaching the foot of the outstretched leg of the patient to the pulley block 29 and moving the outstretched leg sideways towards the other leg; alternatively, the patient may face in the opposite direction with both legs together and with one foot attached to the rope section A by. the pulley block 29, exercising the abductor muscles bymoving the at-.

tached leg sideways away from the other leg.

The apparatus above described may be come bined with auxiliary pulling apparatus for arm, shoulder, chest or trunk exercises. pose the rear end of the base platform may be extended laterally to either right or left thereof, or to both sides (as shown in Fig. 1) to carry an additional weight support. Platforms 4| secured Fig. 6.

For this pur-' to the frame members It support spaced upright auxiliary posts 42 which are rigidly connected to the main frame by members 43 joining the upper ends of posts I2 and 42. An additional movable support 44 for a weight 46 is guided for vertical movement on each pair of posts 42 and is suspended from an additional movable pulley connected to the platform 44 by means of a rod 41. The front posts 42 are provided, at their upper ends, with swivelling pulleys 48. A separate length of rope (shown in heavily dotted lines in Fig. 1) is passed around the pulleys 45 and 48. One end of the rope 55 may be anchored to the rear post 42 or, as shown in Fig. 1, the end of the rope may be provided with a weight 56'which is dropped through a slot 5'! provided in the rear post 42 which, for this purpose, is made tubular. The other end of the rope 55, after passing around the swivelling pulley 48, is secured to an arm, shoulder, trunk, chest, head or other harness, patient.
