Sept. 13, 1955 A. L. HlNTZ EAR-PHONE HEAD SUPPORT Filed Feb. 25, 1952 United States Patent EAR-PHONE HEAD SUPPORT August L. Hintz, Altadena, Calif.
Application February 25, 1952, Serial No. 273,225
3 Claims. (Cl. 179-156) This invention relates to ear-phone head supports. Among the objects of my invention is to provide a readily removable padding over spring bows which are usually employed for supporting ordinary ear phones in place over the ears of the user. The present invention provides an improved structure which relieves objectionable pressure of the device on the head of the user during long continued use and which is readily removable and can be easily replaced after removal.
In the accompanying drawing forming part of this specification, Fig. 1 is a front elevation of an ear phone head set showing my improved padding applied thereto; Fig. 2 is an end elevation of a portion of the structure shown in Fig. 1, when my improved padding is partly' open and the spring bows exposed; Fig. 3 is a section taken approximately on the line 3-3 of Fig. 2, and Fig. 4 is a section showing an alternative construction of my invention.
In the drawing, A-A represent a pair of ear phones which are adjustably supported in the usual manner by the opposite pairs of yoke members 10, shafts 11 and clips 12, the latter being attached to the opposite ends of a pair of spring head bands 13.
In use the ear phones are adapted to be held tightly over the ears of the user by the spring head band members 13 which engage over the top of the head of the user in the usual manner.
Long continued direct contact against the head of a user by the spring head bands such as 13 has been found objectionable and it is the primary object of my improvement to provide improved cushioning means below the head band or bands and against the head of the user. To this end I employ a longitudinal strip of comparatively thick foam rubber B immediately below and throughout the length of the pair of head bands 13-13. This strip of thick foam rubber is encased or jacketed in a longi- 5 tudinal strip of cloth fabric 14, the side edge portions of the latter being folded inwardly and longitudinally and stitched at 15 through the side edge portions of the pad B 2,717,930 Patented Sept. 13, 1955 ice so as to form a pair of longitudinal seams 15-15 (Fig. 1), with a pair of adjacent closing flaps 17-17. In this manner the covering of fabric and the cushioning pad B becomes an integral structure.
The pad of soft material B is clapped by the cover laterally and longitudinally around the pair of head bands 13-13 by the lateral flaps 17-17, the latter having their adjacent edges 18-18 separably closed and secured together longitudinally by the slide fastener C. In this manner the foam rubber cushion B can be easily and quickly adjusted on or removed from the supporting bands. When adjusted it provides a soft cushion which overcomes previous objections resulting from long continued service.
In the modification shown in Fig. 4, the contiguous edges of the flaps 18-18 are secured permanently together by a seam of stitching 19 and the outer edge portions 20-20 of the flaps can be finished ornamentally as shown or with plain tailored edges.
Changes and modifications are contemplated within the spirit of the invention and the scope of the following claims.
1. An ear phone head set, comprising a transverse wire head band, a buffer composed of foam rubber engaged lengthwise below and on said head band and having side flaps closed inwardly over said buffer and engaged at their inward edges to hold the buffer on said frame, and slide fastener means between the contiguous meeting surfaces of said flaps by which the flaps are releasably engaged to retain the buffer on said head frame.
2. An ear phone head set support, comprising a transverse ear phone supporting frame, a buffer having inturned side flaps engaged over said frame, and slide fastener means separably engaged longitudinally between the contiguous inturned portions of said flaps by which the butfer is held in place on said supporting frame.
3. An ear phone head set, comprising, a flexible supporting head frame having united resilient supporting longitudinal side arms and ear phones at their opposite ends, a resilient pad engaged between said side arms, a cover folded over said pad and engaged around said side arms, and slide fastening means applied to the contiguous inward folded edges of said cover by which the pad is removably held on said arms.
