H/5 A TTOENEX Patented July 13, 1948 This invention relates to so calledhead gear gogglsand is concerned primarily with-the mode of mounting a pair of goggles on a headgear.
v Aheadgear goggles-of the type with which this invention is concerned includes as essential elements-a headgear and a pair of goggles. The headgear is adapted forsnug fitting on the wearers head and is intended to constitute theanchor'age to which the goggles are attached. While the headgear is more or lesspermanently worn, that is, it will remain in position during the worldngtday, the gog les will, vfromtirme to time, bee-swung from a protective position into anout tv the way position above the wearer's forehead. In-providinga means for attaching the goggles to.,the headgear so as to permit of thenecessary manipulation-,it is desirable that a high degree of. simplicity. be achieved and the, number of partsheld down to anabso-lute minimum. This not. only assures of easy operation as thegogglesare" being,moved ,-,but eliminates any parts which might obstruct the vision.
V Accordingly, this invention has in view asiits foremostobjective, the provision of a headgear gogglesof-the type aforesaid in whichmeans is provided foroperatively attaching :the goggles to the headgear centrally of the goggles.
More in detail the inventionhas as its object theaprovision of ayheadgear goggles: of the type noted in whichthe attaching meansis secured to the bridge ofthe goggles.
In. order to-insure accurate fitting. of the goggles the goggle elements have been hingedly connected. In accordance with this invention a certain amount of relative pivotal movement between the" individual goggle elements is permitted by the attachment to the headgear.
Aiurther object of the invention isthe-provision',.in a headgear goggles of the character described,v of "attaching means comprising a link havinga pivotal connection at one end of the headgear and a pivotal connection at the other endjwith the bridge of the goggles. Associated with eachof the pivotal connections is meansfor generating friction which functions to maintain thergoggles in an adjusted position.
Another important feature ofthepresentinvention resides in the particular meansfor connecting the attaching means to; the goggles bridge.- In accordance with this invention, the link'is pivotallyjoined to a bracket-and-there is a pivotal connection between each individual goggle elementand this -bracket.;- Thus: each goggle element may! he pivoted slightlpwith respect? torthe bracket.=-= Thesrhinged connection between the The 1 men, therefore, comprises a head-- gear os'z', consisting" of aheadg'ear end a-pair or mean onriecte'djgog'g'l demerits which are gear. goggles made in accordance with'the precents: of this invention;

The latter may be provided with a sweat-band such as indicated at M, in accordance with common practice. It is evident that this frontpart i3 is intended to be snugly fitted over the front part of the wearers head. A rear headgear part is designated at I5 and as shown is pivotally attached to, the front part ill by the pivotal connections Hi, there being a pivotal connection on each side. This rear part i3 is rendered adjustable in length by adjusting means shown at H.
Adjusting devices of this type are well known in this field and any such means of adjustment which is found satisfactory may be employed. It is evident that by availing of the adjusting device 11, the headgear H in its entirety, may beaccurately fitted on the head of any particular wearer.
Th'e goggles G are shown as comprising the individual goggle elements 48 and I9. The actual assembly of each of these elements [8 and i9 is not a particular part of this invention. Ordinarily each will include an outer protective glass which is replaceable and the inner ray-filter, which will protect the users eyes from excessive light. The outer glass protects the ray-filter from flying particles of metal or other material which might damage the more expensive rayfilter. These glasses are removably contained in the circular frames illustrated. The frame of the goggle element [8 is shown as being provided with a lug carrying hinge ears 2|. The frame of the goggle element 89 is provided with a lug 22 which carries hinge ears 23 that are complemental and interfitted with the ears 2|. A hinge pin 24 passes through aligned openings in the ears 2| and 23 to establish the hinge connection. It is notable that there is a loose fit between this hinge pin and the ears. This looseness permits the adjustment which will later be described.
The connecting attachment C includes a bracket 25 which extends across the top faces of the lugs 23 and 22. At one end the bracket part 25 is pivotally joined to the lug 26 by the pivot screw shown at 26. At the other end the bracket 25 is pivotally joined to the lug 22 by the pivot screw shown at 21. It is evident that the pivotal connections 26 and 21 between the bracket 25 and the lugs 20 and 22 formed on the individual oggle elements, together with the looseness in the hinge joint defined by the hinge pin 24 and openings in the ears 2i and 23, permits a certain amount of angular adjustment between the individual goggle elements 18 and I3.
Included as a part of bracket 25 are a pair of spaced ears 28. Another bracket 29 is permanently secured to the headgear H by rivets shown at 30 which securely anchor the bracket 29 to the front part I!) of the headgear. This bracket 29 also carries a pair of spaced ears 3| and the spacing of these ears corresponds to the spacing of the ears 28.
A connecting link L is made up of two complemental halves 32 and 33. At one end the link L is positioned between the ears 3| and pivot pin 34 passing through aligned openings in the ears 3! and halves 32 and 33 establishes the pivotal connection. It will be noted that the openings through the link halves 32 and 33 are enlarged as shown at 35 to provide a counterbore which receives an expansion spring 36. This expansion spring tends to spread the link halves apart and press them against the inner faces of the ears 3| and thus create a required amount of friction. The other end of the link L is similarly positioned between the ears 28 and the pin 31 and establishes the pivotal connection in the manner above described. A spring 33 will also be located in a counterbore 35 and disposed about the pin 31 to generate friction at that end of the link.
With the device thus described, it is apparent that suitable provision is made for angularly adjusting the goggle elements so that they will snugly fit about the eyes of the wearer. The friction created at the pivots 34 and 31 serves to maintain the goggles either in a protective position in front of the wearers eyes or in an out of the way position above the wearers forehead.
The goggles may be moved by grasping them at any convenient part, such as one of the handles shown at 9, and the central location of the connection to the headgear renders such manipulation a matter which is easily carried out. Moreover, the anchorage to the headgear is firm and secure and will not be impaired by continued use of the device.
Figures 4 and 5 illustrate a modified form of the invention in which the connection between the headgear H and goggles G is shown as including an additional pivotal connection. Thus, the pivotal connection at 34 to the bracket 29 on the headgear remains the same as does the connection at 31 to the bracket 25 on the goggles G. However, between the pivots 34 and 31 the structure is changed from the form shown on Figures 1, 2 and 3. A link identified as l is secured at one end to the pivot pin 34 in the manner above described, and a second link I1 is connected at one end to the pivot 31. These links I and I1 are formed of complemental halves as above described in connection with the link L and are joined together intermediate the pivots 34 and 31 by another pivot pin 33. This pivot pin 38 may also be provided with a spring for creating friction as above described in connection with pivots 34 and W. The purpose of this additional pivotal joint in the connection C is to facilitate the manipulation of the goggles G with respect to the headgear H as it provides a variety as to adjustment and number of positions which are obtainable in excess of that provided by two pivotal joints.
While preferred specific embodiments of the invention are hereinbe'fore set forth, it is to be clearly understood that the invention is not to be limited to the exact construction illustrated and described because various modifications of the details may be provided in putting the invention into practice within the purview of the appended claims.
