` PATENT Aoi-Ficlaz Wm I. RUTH, 0l' TORONTO, QNTABICLAIADL ma ran appimaon nea apra a, mi. semi n. 52u14.
The principal obects of this invention are to materially re uce the discomfort and injurious effects to persons occupy' a kneeling posture and to provide a pad oex 'tremely soft resilient material' which may be very readily placed in position for use and which may be secured to the knee over a dress or may be fastened securely around `the leg as may be desired.
he principal features of the invention consist in the novel construction of a pad of spon e rubber and in the arrangement therein o means to which external fastening members are adjustably secured.
In the accompanying drawing, Figure 1 isa rspective view of my improved pad showing`a pair of adjustable spring clips for securing the pad in position u n the knee. Figure 2 is a plan view of t e pad showin one of the spring clips swung parallel with the pad.
Figure 3 is a transverse sectional view o f the pad taken centrally through the holding members and showinga strap holding device arranged thereon.
Fi re 4 is an elevational view illustratin t e manner of using the pad.
umerous forms of pads for protecting the knees of persons when occupied in a kneeling position have been devised but the present invention-pro s the novel use of a well-knwn materia suchas sponge rubber which presents a marked degree of im provement in the art.
As illustrated in the accompanyin drawing the pad 1 is in plan substantia ly rectangular in rounded ends 3. This pad is formed in section, both transversely and longitudinally, with a rounded surface 4 thus providing the pad with a thick ta ring to comparatively thin edges 5.
e pad is moulded so that its exterior surfaces present a` smooth surface while the interior is filled with small gas-lilled cells which is the ordinary internal sectional feature of all sponge rubbers, the cells being formed by the gasifying of certain materials milled into the rubber. A
5 A metal plate 6 which is dished to conform, having parallel sides 2 and central cross-section length and the ends of these lugs are preferinward and are` provided ably bent slightly with slots 8 whic are adapted toreceive the end members of aY fastening strap 9, as illus- .trated in Figure 3.
Spring clip members 10 are secured to thev lugs 7 preferably by pivotal connections inthe formof rivets 11 and the clip.members are preferably formed each witli a slidable extension 12 which are curved inwardly at heir ends to fitaround the curvature of the eg. 1 y` The slidable adjustment enables the user to adjust the clips to the most comfortable position. These members are a snug slid fit but any suitable form of means for loc ing them in an adjustable position may be provided.
The pivotal arrangement of the clips 10 enables their being turned downwardly parallel with the pad sothat they will be out of the way if a strap fastener 9 as shown in Figure 3 is desired to be used and the pivotal arrangement also enables the pads being placed snugly together, both for packing and storing purses when not in use. It will be readily understood that the soft sponge rubber will provides. very resilient pad which will protect the knees from injury and discomfort when bearing the weight of the body upon a hard surface. The smooth vouter surface of the pad will not collect dirt,
as would the cellular interior structure and it will resist wear and in order to obtain the maximum wearing value, the bottom covering will preferably be made thicker than that of the top. Further, the curved bottom surface of the pad will allow freedom of movement in a rocking action, either sideways or longitudinally of the pad and the curved surface also keeps the edges clear ofthe oor so that they will not become marred or torn.l
gs 7 which project from the side 2 v :,soasel What I claim as my invention is: 1. A knee pad, comprising in combination a resilient adof moulded rubber, said pad bein rein orced bodily by a. reinforcing 5 meta plate embedded therein to impart body rigidity thereto, said late havinr attachment lugs projecting om the edges, and means secured to said lugs for securing the pad to the leg of the wearer.
2. A knee pad, com rising in combination,
a moulded pad of rub er, said pad bein reinforced bodily b a metal plate em ded therein to impart body rigidity thereto, said plate 'having lug extensions projecting from the sides of the pad, spring members pivotally secured to said lugs and extendin therefrom, and extension clip members slida ly mounted on said spring members at one end and being curved inwardly at the other end to grip the leg of the wearer.
3. A knee pad, comprising in combinationY a moulded pad of rubber, said pad bein re- Y inforced bodily by a metal plate embe ded in the pad to impart body rigidity thereto,
said plate havin lug extensions projecting from the sides o the pad, and spring metal clips secured to said lugs.
4. A knee pad, com rising in combination a moulded ad of rub r, said pad being relinforced bo ily by a metal plate embedded in the pad to impart body rigldity thereto, said plate having lug extensionsprojectin from the sides ofthe sad, and s ring met clips pivotallysecure to said ugs, the pivotal connection of saidclips to said 1u rmitting the pad to ivot relative to sai c 1 and the foldin of e clips into compact re ation to ,the-pa WILLIAMJ.
