Qct..28 1952 R. E. MAXANT EAR MUFF FRAME AND MOUNTING Filed Feb. 23, 1950 INVEN TOR. $5925 BY -Z ATTORNEY.
Patented Oct. 28, 1952 EAR MUFF FRAME AND MOUNTING I Robert E. Maxant, Riverside, IlL, assignor to Maxant Button and Supply 00., a corporation of Illinois Application February 28, 1950, Serial No. 146,799
This invention relates to the supporting frame and the mounting whereby ear muffs are hinged and swiveled on a head piece, either a head band alone or one concealed in a cap.
Heretofore, ear muffs, of the type where the fur or pile fabric has been secured to a stamped metal frame, have not been provided with a frame and mounting which would appropriately coact to yieldingly hold the ear muff in a fixed angular relationship to the supporting head piece. Generally such frame and mounting has been so loose that the ear muff could not be made to press against the head of the wearer or be retained in a position away from the ears if the wearer desired. Such ear muffs, when worn in high wind, are quite likely to flap or stand out away from the ears of the wearer or flop down around the ears when the user did not want them on the ears, but wanted to reain the band or cap on the head. Moreover, the former manner of attaching the mounting to the frame presented a construction so weak that careless movements of the muff would often result in the distortion of the mounting or a breaking off of the muff from the head band.
The main objects of this invention, therefore, are to provide an improved form of frame construction for ear muffs which provides for a mounting that permits these muffs, when attached to a head piece, to be retained on the head piece in practically any position desired by the wearer; to provide an improved construction of this kind which insures a firm friction grip of the muff mounting on the muff frame so as to insure the retention of the muff in any angular disposition to which it might be set; and to provide an improved frame and mounting of this kind which is economical to manufacture and durable in use.
In the accompanying drawings:
Fig. 1 is a perspective view of a complete ear muff with the individual muffs assembled on the ends of an expansible spring head piece;
Fig. 2 is a perspective view of the improved frame and mounting on which the pile material or fur piece is assembled;
Fig. 3 is an exploded view of the several parts of an ear muff embodying this improved frame and mounting;
'Fig. 4 is an enlarged fragmentary sectional detail of an ear muff and this improved frame and mounting taken on the line 4-4 of Fig. 1.
An ear muff formed with a frame and mounting embodying this invention, comprises a pile fabric or fur pad 6 secured around the peripheries and between the frame member 9 and a retainer ring I, and with which is usually associated a liner 8.
These several parts are assembled on a machine such as shown in Patent No. 2,324,009.
This invention relates primarily to the construction of the frame 9 whereon is secured a wire it! to which is hinged the mounting mem ber II.
As clearly indicated in the drawings, particularly in Fig. 2, the frame member 9 is a ring-like sheet metal stamping, slightly elliptical, embossed circumferentially between the outer and inner peripheries or bounding edges 9a and 9b thereof so as to enhance its rigidity. Adjacent one of the lesser arcs of the frame there is formed an integral web I2 which is notched at I3 and bridged by the wire I0. The web I2 is formed by increasing the amount of metal between the outor and inner peripheries 9a and 9b. Preferably this web [2 is so formed that the inner bounding edge thereof constitutes a chord or free edge I2 located at one side of what generally may be termed the axis or center A of the frame member 9. The notch I3 extends inwardly from the chord or free edge I2 of the web toward the periphery 9a.
The wire is round and the ends extend through apertures I4 in the web I2 which ends, as herein shown, are bent outwardly to firmly secure the wire In in place. Obviously, the wire ends could be bent inwardly if desired. The wire In is thus in effect disposed in the plane of the web I2 and bridges the notch I3 thereby constituting a cylindrical bearing for the mounting member I I.
The mounting II is a strap of spring metal bent U-shaped with at least one of the leg parts [5 crimped as at I6, so that both leg parts are normally disposed close together and the bend I'I conforms to the shape of the wire and is in contact with the wire throughout the major periphery of the bend I'I. By virtue of this formation of the mounting member II it has a relatively large area of contact with the wire Ill, and even prior to the insertion of the fastener I8 will tend to maintain an angular position to which it is set. When the parts I5 are compressed together by the fastener I8 the mounting I I will positively retain any desired angular position with respect to the frame 9 to which it may be adjusted.
The fastener I8 is herein shown in the form of an eyelet I8 (see Fig. 1). It could be a rivet if preferred. Such a fastener also serves to, se-- cure the ear muff to the head piece and provide a swivel connection which permits the muff to be swung on the head piece I9 through 360 degrees in the plane of the frame 9 and yieldingly retained at any point in said 360 degrees of swinging.
The fastener I8 so disposes and holds these leg parts I5 that the bend I 'I will so firmly maintain its friction contact with the wire I0 and allows the muff to be disposed and yieldingly held at any angular position in which it may be placed with respect to the frame member 9 within the range of practically degrees. Accordingly, when an ear muff with a frame and mounting of this kind is attached to a head piece I9 the wearer is assured that the muffs will be held firmly in any desired position: against the ears or away from the ears, upwardly above the ears or rearwardly 'or forwardly of the ears.
Moreover, if Worn in a heavy wind there will be no flapping of the muffs. Furthermore, the wire l0, fixed as it is on the web l2 of the frame 9 affords a support for the mounting ll of such strength that it is not easily distorted or broken if one hurriedly or carelessly unfolds or folds the muffs and head piece or stores the device when not desired for use.
The head piece [9 may be either a pair of spring-metal, relatively-adjustable bands, as
shown in Fig. 1, or a single spring band concealed in the band of a cap.
Variations and modifications in the details of the structure and arrangement of parts may be restored; to within the spirit and coverage of the appended claims.
