As shown in the drawings there is further provided a bracket or support piece that is indicated generally by the numeral 48, and the support piece 48' includes spaced apart leg portions 49 that have end sections 50 for engaging openin-gsor recesses 51 in the end portion of the platform 35, and pins or securing elements are adapted to be used for maintaining the end portions 50 secured within the recesses 51. The support piece 48 further includes a cross element or crosspiece 52 which has a foot engaging element 53 connected thereto, and the foot engaging element 53 may be held in place by means of set screws 54, FIGURE 1.

The chair of the present invention further includes a pair of similar spaced apart inverted V-shaped support members that are indicated generally by the numeral 56, and each of the support members 56 includes a bight or horizontal portion 57 as well as generally vertical front and rear legs or depending

portions

58 and 59, and the lower ends of the

portions

58 and 59 are adapted to be snugly received in the apertures 46 of the platform 35, and securing elements 60- are adapted to be used for maintaining the lower ends of the portions 58 and *59 secured within the apertures 4-6.

Secured to or formed integral with the portions 59 and extending rearwardly therefrom are racks 61 which have a plurality of teeth 62 thereon, and pins 63 extend outwardly from opposite sides of an adjustable back rest 64 for coaction with the teeth 62 of the racks 61 where- 3 by the back rest 64- can be maintained immobile in its various desired adjusted positions. Stop members or elements 65 are formed on the rear ends of the racks 611 for limiting backward tilting movement of the back rest 64. As shown in the drawings the back rest 64 includes a frame 66 that embodies spaced apart side sections 69 and the lower portions of the side sections 69 are provided with slots or cutouts 67 for the projection therethrough of a pivot mounting rod 68, FIGURE 10. Hand grips or handles 70 are secured to or formed integral with the upper portions of the side sections 69 of the frame 66, and the numeral 71 indicates a cushion unit which is suitably secured within the frame 66.

There is further provided a pair of similar body members 72 which each have a generally L-shape in cross section, and each of the body members 72 comprises first and second portions or

sections

73 and 74 that are arranged at right angles with respect to each other, FI URE 2, land the portion 74 is longer than the portion 73. The portions '73 of the body members 72 are swivelly or hingedly mounted on the seotions 57 of the support members 56. The numeral 75 indicates a cushion element which is suitably secured to the second portion 74 of each body member 72, and a base piece 76 may be interposed between the cushion element 75 and the adjacent portion of the body member 72, FIGURE 6.

The band 41 is adapted to be held in place on the base by means of set screws or securing elements 77, FIG- URE 8.

The numeral 78- indicates a cutout or slot in the upper section 23 of the base 22, and the cutout 78 provides clearance for the tongue 38 to move through in order to engage a groove 34 in the standard 33.

From the foregoing, it is apparent that there has been provided a chair which can be used for various purposes, and in use with the parts arranged as shown in the drawings, it will be seen that for example an adult can sit on the chair when the parts are in the position of FIG- URES l, 2 and 3, and the cushion member 47 is adapted to he sat upon by the adult or other person. With the pants in the position of FIGURES 1 through 3, the portions 73 of the member 72 function as comfortable and convenient arm rests, and the feet of the person sitting in the chair can engage the element 53. The back rest 64 can be adjusted to a desired angle as desired or required. In addition the standard 33 can be adjusted up or down in the base 22 so that the platform and associated parts can be raised or lowered as desired or required.

To adjust the standard 33 and platform 35 and associated parts up or down, the barber or other person operating the chair need only step on the member '28 so as to move the actuator 27 which is operatively connected to the valve 26, whereby hydraulic fi-uid or other actuating medium such as compressed air can be supplied from a suitable source of supply such as a reservoir tank and such actuating medium can be pumped by means of a suitable pump from the conduit 36 into the conduit 25 whereby the actuating medium 32 will enter the chamber 24 to raise the standard 33 in the chamber 24 of the upstanding section 23 of the base 22. Since the platform 35 is rigidly affixed to the upper end of the standard 33, it will be seen that this upward movement of the standard 33 will result in corresponding movement of the platform 35 and associated parts. By moving the valve 26 to a dilferent position as for example by engaging the element 28 with the foot, the actuating medium 32 can flow outwardly from the chamber 24 through the conduit 25 and out through a conduit such as the conduit 31 in order to permit downward movement of the standard 33 in the chamber 24.

The keeper 36 is pivotally connected as at 39 to the ears 40 on the band 41, and the band 41 is held in place by means of the set screws 77, FIGURE 8. Thus, by stepping on the portion or element 37, FIGURE 1, the keeper 36 can be pivoted in a counter-clockwise direction in order to withdraw the tongue 38 from the particular groove 34 in which it is engaged, and the opening 78 in the upstanding section 23 provides clearance for the tongue 38 to work or move through in order to engage or disengage the corresponding groove 34. With the tongue 38 out of engagement with the groove 3-4, there will be no interference with rotation of the standard 33 in the chamber 24 so that with the tongue 38 out of en gagement with the grooves, the standard 33 can rotate and thus the platform 35 and associated parts can rotate in order to provide a means for conveniently positioning a person at a desired location, and the platform can be turned through three-hundred and sixty degrees. After the standard and platform have been rotated to a desired position, foot pressure on the element 37 can be released whereby the spring 42 will have a tendency to bias or urge the tongue 38 inwardly as for example as shown in FIGURE 1 whereby the tongue 38 will engage a corresponding or proper groove 34 in order to prevent inadvertent or unwanted rotation of the standard 33. Due to the provision of the elongated grooves 34 and the previously described tongue 38, it will be seen that the standard 33 can be adjusted up or down and this up and down adjustment can take place without any rotation of the standard since the tongue 38 will engage a groove 34 in order to maintain the standard in an aligned position as it is adjusted.

With reference to the adjustable back rest 64, the back rest 64 includes the frame 66 which has the slots 67 in the lower side portion 69, FIGURE 10, and the pivot mounting pin or rod 68 extends through the diametrically opposed slot 67 in the opposite side portion 69. Thus, with the parts arranged as shown in FIGURE 1 for example, it will be seen that to adjust the back rest 64 to a different angularly position, it is only necessary to grip the handles 70 and :lift up on the back rest 64 whereby the slot 67 will provide sufficient clearance for the back rest 64 to be raised upwardly a suflicient distance to permit the pin 63 to clear the teeth 62 of the racks 61, and with the pin 63 up out of engagement with the teeth 62, the back rest 64 can be pivoted in a forward or reverse direction to the desired location, and then when pressure on the handle 76 is released, the pins 63 will engage the teeth 62 to maintain the back rest 64 stationary or immobile =in its desired adjusted position. The portions 65 function as stop members to prevent the back. rest 64 from being tilted back too far.

When an adult or the like is using the chair 20 of the present invention, the parts are in a position such as that shown in FIGURES 1, 2, and 3 so that the person sits on the cushion member 47, and with the parts in this position the sections 73 function as comfortable and convenient arm rests for the person supported on the cushion member 47. However, when a child or small person is using the chair, the body members 72 are pivoted or swivelled inwardly from a position such as that shown in FIGURES 1, 2, and 3 to a position such as that shown in FIGURE 4, and this swivel action or movement of the body members 72 is brought about due to the pivotal connection of the sections 73 on the portions 67 of the support member 66. Thus, the members 72 can be moved to the position shown in FIGURE 4, whereby the cushion element will be arranged in aligned horizontally disposed relation so that the pair of cushion elements 75 would provide a raised seat for the child or other person. When the chair is to be used by an adult, the parts can be returned from the position shown in :FIGURE 4 to the position such as that shown in FIGURES 1, 2 and 3. With the parts in the position of FIGURE 4 the sections 74 are supported on the cushion member 47.

The cushion unit 71 is suitably afiixed to the frame 66 in order to comfortably and conveniently support or engage the back of the user of thechair.

The parts can be made of any suitable material and in different shapes or sizes.

It will be seen that according to the present invention the childs sea-t structure or body members can be applied to the arms of a chair such as a barber chair in such a manner whereby the body members or sections of the childs seat can be swung into and out of position in order to permit the chair to be utilized with equal facilities and for the accommodation of both adults and infants or children.

The chair of the present invention can be readily placed in a reclining position so as to function as an all purpose chair.

According to the present invention there is provided an improved folding arm type of chair wherein there is provided a pair of folding arms or body members that -Will fold over into the seat of the chair so as to raise the seat of the chair whereby it can be used for adults and children, and the present invention also includes a safety means for keeping the chair from turning, and this safety means which includes the keeper will operate independently from the hydraulic lift of the chair, and the hydraulic lift can be of any suitable construction. Thus, the chair of the present invention includes an improved and novel means for raising the seat of the chair together with the folding arm rests, and the chair also includes a means for preventing accidental inadvertent rotation thereof. The chair will not turn until foot pressure is applied to the element 37 and this functions as a safety locking arrangement.

The chair of the present invention thus includes the folding arm rests which are adapted to fold from the sides of the chair over into the seat of the chair, and wherein the seat can be raised or lowered and the chair can be used by adults or children, and the present invention includes the hydraulic lift and mechanical foot operated safety device which is independent of the hydraulic lift and which will keep the chair from turning until released. Back rests can be placed at any desired angle, as previously stated.

While certain embodiments of the invention have been illustrated and described in detail, it Will be obvious that the invention may be otherwise embodied and the di mensions and interrelation of parts changed so long as the objects of the invention are attained.
