This invention relates to improvements in beauty parlor chairs.

The general object of our invention is to provide an improved reclining ch'air for use in beauty parlors.

A more specific object of the invention is to provide a novel operating mechanism for a reclining beauty parlor chair.

Another object of the invention is to provide a reclining chair having a seat and a back and having a hair dryer thereon and wherein novel means is provided to cause the distance between the seat of the reclining chair and the hair dryer to remain substantially constant in all positions oi the chair back.

Another object of the invention is to provide novel control means for controlling the operating mechanism of a reclining chair back.

Referring to the drawings by reference characters we have shown our invention as embodied in a beauty parlor chair which is indicated generally at I0. As shown the chair includes a base II having a rear portion I2, sides I3 and a front I4. From the sides I3 arms I5 extend upwardly. The arms I5 are hollow and are provided with suitable inside and outside upholstered panels I6 and II, the latter of which extend downwardly to cover the sides I3 of the base. The base supports a seat member I8 which is suitably upholstered.

Mounted within each arm we show a vertically extending support member I9 secured at its lower end to the side members I3 as by bolts 2U. Each' support member at its upper end includes a bent end portion 2| secured by bolts 22 to the arms I5.

Pivotally mounted on a pin 23 on each support I9 we show a rearwardly extending link 23. Each link passes through a slot 24 in the back of the arms I5. Each slot 24 is covered with a soit rubber closure member 24 (see Fig. 6) which is `slitted as at 24a. The sides of the slits 24a are normally in engagement but since the rubber is soft the links 23 may move in their associated slots. Each slot thus remains closed preventing ready insertion of objects therethrough. The links 23 at their ends remote from the support I9 are connected to lianges 24" on a chair back 25 which is suitably upholstered. The chair back includes a tubular support 26 in which a hair dryer tubular supporting rod 2l is slidably mounted and is held in adjusted position by a thumb nut 28. A spring 29 serves to counterbalance the weight of the rod 2l and the hair dryer which will be presently described. The support 26 includes a longitudinal groove 33 which matches with a groove 3l on the rod 2l so that rotation of th'e hair dryer in the tubular support 26 is prevented.

Mounted within the base Il we show a transverse support l32. Secured to the support 32 we provide rearwardly extending

supports

33 and 34. The support 33 is disposed in a vertical plane and at its rear end is secured to a foot member 35 arranged on a member 36 mounted in the base and secured to the front and rear of the base.

The support 34 is horizontally disposed and at its rear end engages a transverse member 31 secured at one end as at 38 to one side of the base. The other end of the transverse member 31 is integral with the foot member 35 previously mentioned.

The

transverse members

bearings for an elongated screw 39 which includes a cylindrical portion projecting at one end beyond the transverse member 3l. The portion 4l) receives a worm wheel 4I which meshes with worm gear i2 on the armature shaft 43 of a reversible electric motor 44, and the construction is such that when the motor is operated the screw 55 will be driven.

The screw 59 receives a nut 45 .which is elongated and which at one end is provided with a ange 45. This ange t5 (Figs. 1 and fi) includes spaced ears 4l. The ears 41 are pivoted to one end of an arm 55 by a pin 49. The other end of the arm 48 is pivoted on a pin 5i] which is sup- The ears 5I are mounted on the back 25 at the lower end of the tubular supported in ears 5i.

port 25.

When the motor it!! is operated the screw 39 will be rotated and the nut will be moved along the screw thus moving the arm d8 and causing vthe back to be swung about the aXis of the pins 23 so that as the nut is reciprocated the back is raised or lowered depending upon the direction of rotation.

The axis of the pins 23 is disposed approximately in alignment with the axis of the pelvis of a person seated on the seat I8 so that as the back is moved the head of a person in the (hair dryer) to be presently described will remain substantially in the assumed position in the hair dryer.

4A hair drying unit 52 is pivotally supported at .53 on the upper end of the rod 27 which is adjustably supported in the tubular support 25 secured to the back portion 25 previously described. For further adjustment of the drying unit 52 we provide a thumb screw 55 threadedly engaging the arm 2l' and which includes a rubber covered inner end engaging the hair dryer. The drying unit 52 includes an outer shell 55 .(Fig. l) having an inner lower shell 5l' spaced therefrom and supported thereon by brackets 58. The inner shell 5l is provided with vents or louvers 5d through which air, warmed by a heating element 55 and blown by a fan or blower 5I driven by a motor 52 may flow. In order to further direet the air over the hair the outer shell 55 is provided with an inwardly and upwardly directed circumferential ange 53 which is preferabiy covered with a protecting rubber strip 86.

g Mounted in the dryer 52 we show our new combination shoulder and head rest 55 which includes a U-shaped support member 5S provided with a foot portion 5l. A substantially rectangular frame member 68 is superimposed on the member 56 and is held in place thereon by welding portions 'it (which are continuations of the frame 58) to the member 65. The frame 58 includes a central aperture 69 and is further provided with' leg members lll.

A clamp member Il which includes sides 'i2 is pivotally connected at 'i3 to the frame and the underside of the clamp is grooved as shown in Fig. .1.0. lThe clamp member is normally urged against the frame by springs 1li. Each springlfl includes an end 'lita secured to a looped portion The other end of each spring is secured as by a rivet Mc to the outer When the clamp like may be placed thereon. After the hair net is in place the clamp member is allowed to swing down to engage the frame 68 to thereby tightly secure the net in place as shown.

The portions 76 on the lower end of the frame 5% support a hinge 78 and. this hinge in turn supports a shoulder rest 'H which includes a cushion 7) of rubber or other suitable soft material which lserves to support the shoulder of a person in the chair. The shoulder rest cushion 19 tapers in thickness downwardly and is provided With suitable apertures S5 to provide increased resiliency.

. In use the legs 'i5 on the frame engage the inner shell 5l' of the hair dryer so that it is held in position. The foot portion 61 of the U-shaped member 55 also engages the inner shell 51 of the drying unit. The. legs 1l) and foot portion 51 are member is raised the springs 'I4 are .tensioned so that the clamp member 'Il is urged into engaged Aposition. by the springs.

When. the clamp member 'il is in the broken preferably so arranged as to support the head rest on the inner shell of the drying unit entirely free from contact with' the rubber 64 on the flange 53.

The construction of the beauty parlor chair Il is such that when the back portion 25 is lowered to the broken line position shown in Fig. l, the back portion and hair drying unit remain in the same relative position due to the fact that the movement is about the axis of the pivot 23 which axis corresponds substantially to the axis of the pelvic joint of the occupant of the chair so that the shoulder and head of a patron engaging the shoulder rest Il does not shift along the rest as the back moves up or down.

Referring to the wiringdiagram in Fig. 8 motor lift includes a lead Si! which communicates with a push button or circuit closure 8| located on one of the arms I5 and which in turn has a lead 32 communicating witha .suitable source of power The motor. includes a second lead 84 which communicates with' a reversing switch 85 which is operated by a nger tip control 86 located on one arm l5 of the chair. When the switch is in the position shown in Fig. S, the lead 84 communicates through a lead 81 with a switch .8d which is normally closed and communicating `with a suitable sourceA of current 8S through' a A third lead Si] from the. motor` 4t also communicates with the circuitclosure 8l previously .ward position as shown in Fig. 8, then when the push botten 8l is pressed causing the nut 45 to v.move rearwardly it lraises the back 25. The motor will continue'to `run as long as the button 8| is held down or until l a spring S5 on the nut 45 contacts the switch 88 and breaks the circuit.

For lowering the back 25 the switch 35 is reversed from the position shown thus when the button Si is pressed, the motor will be driven in reverse causing the nut 45 to move in the opposite direction to lower the back 25. The screw will continue to move as long as the button 8| is .held down or until-thespring contacts the switch 54 and breaks the circuit. .As soon as the .springsmoves from engagement with either the switch 88 or the switch 9d the switch from which the spring moves will immediately be moved by a spring (not shown) to closed position.

It will be noted that the operator may reverse the direction at any point, if desired, by reversing the switch B.

A lead 98 connects a time actuated circuit closing clock $30 on one of the arms l5 with the supply of current S9 and inturn communicates with the heating element ii through' a lead 09. The heating element 60 is in turn connected by a lead to a heat regulator |00 which is connected to the source of power B3. The lead 9S is further connected to the fan motor E2 by a lead l0 The motor includes a second lead |02 connected to speed regulator |03 on one of the arms l5 which is in turn connected by a lead |04 to the source of supply 83.

In use the operator sets the clock control 93 to the time the fan and heater is to run and then th'e intensity of the heat from the heating element 60 is regulated by the regulator |00 and the speed of the fan motor 62 regulated by the regulator |03.

In Fig. 11 is shown a modication of our invention wherein a screw 39 similar in all respects to the screw 39 is provided and wherein the cylindrical portion 40 has a pulley |05 keyed th'ereon and driven by a second pulley |05 through a V-belt |01. The pulley |06 is keyed to a shaft |08 which has a third pulley |09 keyed thereon. The pulley |09 is driven through a V- belt ||0 from a fourth pulley keyed on an arbor shaft 43' of a motor 44',

From the foregoing description it will be apparent that we have invented a novel beauty parlor chair which can be economically manufactured and which is highly efficient in use.
