Application filed November 1, 1924. Serial No. 347,168.
This invention relates to goggles and particularly to the construction of the cushlons, forming a part thereof, for engagement with the head of the wearer. Heretofore, such cushions have been formed in endless rings by joining together the ends of a str1p of rubber tubing, the abutting ends telescopmg over a short piece of tubing of smaller diameter in order to complete the continuous ring. Rubber tubing has been unsatisfactory for this purpose for the reason that the tubing hardened after standing for some tlme, and thus lost its resiliency and, if it Was held in a distorted position, such as by having creases therein, for any considerable length of time, such creases would remain 1n the tubing. Furthermore, the resiliency of the cushion was very materially decreased at the junction between the ends forming the endless ring by reason of the enclosed extra piece of tubing, and this was ob ect1onable because the pressure on the wearers head from the cushions was not uniform. It 1s also desirable that the cushions have a maximum contact surface at the portions engaging the sides of the nose, and to obtain this with a minimum of weight and obstructlon to vision was not possible with the cushions formed of tubing, since it is difiicult to manufacture tubing of non-uniform cross section.
An object of this invention is to provide improved cushions for goggles which Wlll have a minimum weight and a maximum effective cushion surface at the ends adjoining the nose piece; which will have uniform resiliency throughout; which will have longer effective life; and which will be less expensive.
Various other objects and advantages will be apparent from the following description of an embodiment of the invention, and the novel features will be particularly pointed out hereinafter in claims.
In the accompanying drawing .Fig. 1 is an inside elevation of a pair of goggles, having attached thereto cushions constructed in accordance with the invention;
Fig. 2 is a plan of the same with one of the eyepieces and cushions sectioned through the center; and
Fig. 3 is an elevation of one of the cushions before application to the eyepiece.
In the illustrated embodimentof the invention, the eyepiece frames 1, carrying the,
lenses or transparent elements 2, are connected by the usual extensible nosepiece 3, so that the pupillary distance may be varied vwhen the goggles are fitted upon different people. The free ends of the eyepiece frames are provided with the usual strap connections 4 by which the goggles may be supported from the head before the eyes.
The cushions are each provided with aflange 6 around one side, by means of which The cushions 5, in accordance with this in vention, are formed of What is known as sponge rubber, and are molded in integral continuous rings with the integral securing flange 6. WVhen so molded, the surface of the ring may be smooth and the interior of it, as in all sponge rubber, will be porous, so that the ring will have considerable elasticity and resiliency. Sponge rubber does not readily harden in use, and by reason of its texture, will retain its shape and resiliency, even though it may be held under pressure or distortion for considerable intervals. Inasmuch as it is molded in a continuous ring, it will have uniform resiliency throughout, so that the pressure upon the wearers head or face will be uniform.
The ring is preferably formed of greater cross sectional .area'at one point than at another, the cross section tapering between the points of major and minor cross sectional dimensions which are diametrically opposite one another. When viewed in the position of Fig. 3, the circles whichoutline the inner and outer elements or margins of the annulus are eccentric with respect to each other. The rings are connected to the eyepiece frames with the points of greater cross sectional area of the rings adjacent the nose bridge piece 3, so that the point'of maximum thickness is positioned at an an le from the vertical by an amount determined by trial and in accordance with the position of the wearers eye-hollows and so that they will fit snugly against the sides of the 'nose and in the eyehollows beside the nose, and form a more effective seal against the entrance of air or flying objects. At the outer ends of the eyepieces, it is not necessary to provide as effecshape for the purposes of simplicity, but will the faces of difierent users.
be elongated slightly when attached to the eyepieces so as to conform to the usual elliptical configuration thereof. Being molded in a circular form, and then being distorted by tension into an elongated form to match the outline of the goggle lens, the rings are readily adjusted with the larger section thereof in an advantageous position with respect to the-goggle lens, so as to obtain a maximum accuracy of fit and tightness of seal between the cushion and the wearers face.
Goggles of this-type are commonly worn by avlators, or others subjected to air moving at a considerable velocity directly in their face, and it has been found that goggles constructed in accordance with this invention, and with the large cushioI-al surface fitting at the sides ofthe nose, will more effectively and closely fit noses of different configurations. Consequently, the more perfect seal will revent the air or flying objects from reaching the wearers eyes. Goggles with such cushions are more comfortable to the wearer since there are no abrupt changes in resiliency, and the durability of the cushions is greater than in prior constructions.
When the cushions were made of tubin two operations were required, first the molding of the said tubing,'an'd then the converting of strips of the same into endless rings. In accordance with this invention but a single moldin operation is required for the finished article, which greatly reduces the cost and. at the same time provides a more perfect product. This construction is particularly advantageous because of the accuracy with which the cushion can be fitted to a wearers face, with the larger portion of thecircumference adjusted into the deeper hollows in the wearers face beside his nose. The construction has the further important advantage that it is readily adjustable to fit Among aviators, each, of course, likes to retain his own pair of go gles, however, it is readily possible, by the construction above disclosed, after transfer of the goggles from one user to another, for the second user to re-adjust the cushions to fit the particular location of the hollows in his own face. This he may do by simply removing the stitching, re-positioning the cushion to suit the contours of his own face, and then re-stitching in that position.
It will be understood that various changes in the details, which have been herein 1. A resilient cushion for attachment to 4 an eye-piece frame of a pair of goggles, comprisin an elongated integral ring member forme of sponge rubber and having a varying cross section, and means cooperating therewith, and comprising removable stitching, whereby the larger section of said cushion is adapted to be adjusted in a facial hollow, attached to a goggle frame.
