I 'IAND COVERING Filed Oct. 17, v11.942

Patented Jan. 15, 1946 HAND oovEmNG Carroll P. Krupp, Akron, Ohio, assignor to The B. F. Goodrich Company, New York, N. "Y., a corporation of New York Application October 17, 1942, Serial No.' 462,346

(ci. z -166) 16 Claims.

This invention relates to flexible hand coverings and especially to inflatable gloves suitable, for example, for use by aviators with inflatable suits during flight at high altitudes.

The personnel of the high flying aircraft may be protected against the harmful physiological eiects, such as benda of low pressure and oxygen deficiency by inflatable suits having flexible walls and which completely incase the wearer. Heretofore, it has been difficult to secure desirable freedom and flexibility of movement of the hands of the wearer of such suits; since the flexible Walls of the hand covering, portions resist bending and flexing when distended through inflation, the inflated article tending to approach a spherical shape.

Objects of the invention are to provide for effectively protecting the hands together with extensive freedom of movement while the covering is inflated, to provide a covering which is flexible and adapted for bending at lines of natural flexure of the palm of the hand, and to provide for simplicity of construction and convenience and ease of operation.

Other objects of my invention are to provide for resisting movement of the flexible hand covering away from the palm while permitting bending of the hand, and to provide for reinforcing the covering at the hinging zone between the finger and the palmar portions.

Specific objects of the invention are to provide for detachably connecting a glove to an inflatable suit, to provide for convenience in donning the glove, and to provide for ease of bending the glove, when under inflation, while preventing bulging of the dorsal and palmar portions of the same.

These and other objects and advantages of the invention will be apparent from the following description.

In the accompanying drawing which forms a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a plan View of the back of a left hand glove constructed in accordance with and embodying the invention, parts being broken away and in section,

Fig. 2 is a plan view of the front of the glove, parts being broken away and in section,

Fig. 3 is a sectional view taken along line 3-3 of Fig. 1, and

Fig. 4 is a sectional view taken along line 4 4 of Fig. 2.

In the attainment of the objects of the invention a flexible hand covering I0 or glove is provided, suitable" for use with an inflatable suit, and which conforms to the surface of the hand without undue outward bulging While under inflation. The glove Ill is also manipulatable without objectionable effort by the wearer, when the hand isl bent while performing sundry operations such as manipulating the controls of an aircraft.

To these ends, in the arrangement shown in the illustrative embodiment of the invention in Figs. land 2, the hand covering I0 is of flexible, fluid-tight material, such as rubber or other rubber-like material which may have a fabric reinforcement or lining. Bracing elements II to I4 inclusive, preferably of wire, disposed in a palmar portion l5 of the glove I0 in the manner shown prevent undue outward bulging and movementvof the flexible material away from the palm while permitting bending of the hand.r

In Figs. 1 and 2 the glove IQ comprises linger 2I to 25, palmar I5, dorsal, I6, and gauntlet I1 portions interconnected in a fluid-tight manner, and, preferably, so formed that when in normal position, the hand assumes a naturally bent condition thus facilitating further bending of the glove by the hand while grasping an oblect. These portions may have a stockinet fabric lining I8 and I9 for greater strength to resist tear and expansion, when under internal pressure.

For convenience of manufacture the gauntlet portion I1 may be attached to the other portions I5, I6 of the glove at the wrist or carpal area Ila by an overlapping joint and a suitable adhesive like rubber cement, as shown in Fig. 4. The gauntlet may, for greater strength, be made of square woven fabric coated or impregnated with a rubber or rubber-like material and having a stockinet fabric lining I9 adhered thereto as by a rubber cement.

,The operation of bending an inflatable glove,

, when distended under internal pressure, is rendered-especially difcult by bulging of the palmar and dorsal portions. My invention providesrfor desirable freedom of manipulation by'means of reinforcing strip elements II to Ill which prevent objectionable bulging of the palmar and dorsal portions I5 and I6 of the glove I0 and which co-nfine bending of the palmar portion I5 'to lines of natural exure of the palm of the hand. The reinforcing elements II to I4, preferably of steel wire, are disposed in the palmar portion I5 at the hinging zone between the finger 2| to 25 and palmar I5 portions in the manner shown in Figs. 1 and 2.

The spaced-apart wires II and I2 extend from the margin of the dorsal portion IE at the radial side of the hand adjacent the second metacarpalphalangeal or index finger joint, and along the palmai portion I5 at points corresponding. t0 the second to the fth (little finger) metacarpalphalangeal joints and at points corresponding to the distal third of the sec-ond to the fifth metacarpal bones of the palm, and v.continue to the margin of the dorsal portion I6 at the ulnar :side of the hand adjacent the fifth metacarpalphalangeal joint.

A third wire I3 extends along the dorsal p0rtion I 6 at the radial side of the hand following the interosseous area between the rst (thumb) and the second metacarpal-phalangealjoints, and along the palmar portion I5 at the base of the thenar eminence of the thumb, and continues to the dorsal portion I6 at the radial side ofthe hand adjacent the rst metacarpal joint.

For preventing bulging of the hypo-thenar area of the palmar portion I5, it is desirable to provide the wire I4 which is hingedly connected at 28 to vthe wire I3 at the base of the thenar eminence in the region of the interosseous areabetween the rst and the second metacarpal bones ofthe hand. This wire I4 extends along the palmar portion I5 diagonally across the hypo-thenar area -of the palm and continues along the dorsal portion I6 to the fifth metacarpal joint at the ulnar side of the hand.

Preferably, the wires I I to I4 are shaped to conform generally to the contour of the handat the lines of fleXure, before attachment to the glove IIJ. The wires are disposed between a rubber covering V2l) and the fabric lining I8 `of the palmar and dorsal portions I5 and I6 and are sewed as at 29 to the lining, although the wires may be cemented in-place by a rubber cement, for example.

Fabric patches 25 and 21 which are adhered .to

the lining I8 by a suitable adhesive such as rubber 40 cement. prevent abrasion of the lining I8 by curved ends IIa, i211, I3a, and VMaof'the wires I I to I4 and by a hinged connection 28 between the wires I3 and I4. Retaining strips 30, 3l 'and Y32 of rubber or rubber-like materialrare superimposed upon the wires as Ashown in Figs. 1, 2, and 4ancl are adhered in place as by a rubber cement.

From the foregoing description, it will beapparent that the arrangement of the bracing wires `II to I4 effectively prevents undue bulging -and movement of the palmar portion I5 away from the palm of the hand while permitting, bending of the hand. These wires also assistin resisting undue bulging of the dorsal portion I6 by virtue of their end portions being disposed in the Amargins ofthe dorsalportion I 6.

Additional resistance to bulging ofthe dorsal portion I6 is provided by a bellows structure V35 which seals and closes a slit 36 in the dorsal and gauntlet Vportions I6 and I'I. Furthermore, the slit and the bellows structure permit outward extension of the walls of the glove I0 at the wrist enabling the admittance of the vhand therethrough Whileproviding for a snugfit at the wrist I 1a.

As illustrated in Figs. 1 and 3, abellows element 31- .of rubber or rubber-like .material 31a :having a stockinet lining 31h and a separable :fastener 38, preferably ofthe slide fastener type, are -attached at theLmargins of the slit 3E by 'a suitable adhesive, such as rubbercement. A reinforcing cover strip 39 of rubber or woven fabric coated or impregnated with rubber-like .material is superimposed upon the margins o'f 'the bellows element 31 and the fastener 38 at the margins fof the slit 35, and adhered in position by a rubber inflatable suitin a manner-such as is disclosed zinmy copending application Serial No. 445,016.

In donning the glove I0 with the slide fastener .38 being in the disengaged condition, the hand is Vinserted in the opening 4i) and the glove is drawn toward the elbow, the hand sliding freely through at the wrist or carpal area Ila into position in Vthe palmar, dorsal, and finger portions I5, IE, 2I

to thereby assuming a naturally bent condition. The slide 'fastener is then closed by moving a runner 38a. to the position shown in Fig. 1 thus causing the walls of the glove to snugly llt the wrist of the wearer. The glove I0 is next atvtachedtothe elbow joint mechanism Ail asnoted above.

When `the `glove IIJ is united with the inatable suit and under internalpressure, the walls .of the lglove. are distended; nevertheless manipulation by the wearer is easily accomplished. The yfinger portions 2*.I -to 25 may be vflexed `without objectionable resistance; since they -are of relatively small extent as compared to that of the palmar and dorsal vportions I5 and I6.

Maximum freedom -of bending of the palmar portion Yl5 with a minimum of yeiortis achieved lthrough the disposition of the reinforcing or bracing wires 'I -to i4 vin the palmar Yportion at lines of natural-ilexure of the palmof the hand. These wires function to prevent Vundesirable bulging and movement of the palmarportion I5 away from the palm while permitting easy bending of vthe hand. Coincidentally, the wires II -to -III -together with the bellows-structure `35 resist Vbulging of the .dorsal portion.

Variations may be made without departing from .the scope of the invention as vit is defined in the following claims.
