K. EMDE FASTENING MEANS April 2, 1946.

Filed Dec. 31, 1943 r J l l HIS ATTORNEY 7 Prestressed coil spring 30 wound around pivot v 1 pin 25 has one of its ends 3| engaging lever member l9 and the other one of its ends 32 engaging member It so that the end 2| of lever member 1 H! is normally pressed into engagement with member It or presses in a clamping manner the wearers clothing against the wall l5 upon which the fastening device I is mounted.

Whenmounted on the wall or apertured support or closure member It, the pivoted'lever member or wearing apparel engaging member apparel or other supporting means which is inserted between spring biased pivoted lever l9 and V the wall or closure member l5.

Springbiased end ill of lever 19 is displaced from normal engagement with wall l by press- I9 is normally in the position shown in Fig. 51;; I wherein end 2! is pressed against any wearing be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects,

and therefore the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.

I claim: 7 r I i. In a clasp supporting arrangement a member having integrally formed thereon a pair of oppositely extending projections, one of said projections being resilient and extending from a point intermediate the ends of said member on one side thereof at an acute angle therewith in the direction of. one end of said member, the other projection extending from said one side at theother end of said member and being L-shaped, with the vertical portion of the L extending substaning end 22 to the right in Fig. 4, in which case member l9 pivots around pivot pin 26 against the V action of prestressed coil spring 38 and ultimately assumes the position shown in Fig. 5 where end' 22 engages the supporting member i5.

One of the particular features of the present i invention is the ease with which the fastening device or cliplt may be removed from the hearing aid or other device to which it is attached. For example, in the hearing aid apparatus shown in Figs i l and 2, the clip Iii may be removed from the front as shown in Fig. 1, wherein it is eiTective to secure the hearing aid apparatus within the users pocket without interfering with sound transmitted to'a microphone located behind panel and be fastened to the back of the same hearing aid apparatus provided with the same type of apertures l3, l4 and 27, 28 respectively on the front and back sides of such hearing aid apparatus.

The clip or fastening device, shown in Fig. 7

;' detached from the structure it is arranged to support, is readily and easily mounted on the wall f or closure member l5 by (1) inserting projection I2 into opening l4, 2) pressing the composite clip in the downward'direction in Fig. 4 until the projection is in position to be inserted Q through'opening l3, (3) passing projection ll throughopening l3, and (4) then releasing the composite clip id in whichcase the upstanding portion of projection H is pressed upward due to the resilient nature of projection 12 to assume the position shown in Fig. 4.

The fastening device or clip in is easily detached from Wall iii in Fig. 4 by (1) moving the device l6 downward relative to wall" I5, in which case projection i2 is deformed within its resilient limits to a'point where projection'll may be passed through opening [3 and then by (2) pivj o'ting the entire clip I0 at the contact point between projection l2 and wall l5 so as to pass projection ll through opening l3 and then (3) sliding projection l2 out of opening l4. 7 1 7 'It is noted that opening I3 is slightly larger 7 than the upstanding portion of projection II in Fig. '4 so as to allow passage of projection H therethrough. Opening l lis defined by a curved upper wall lllfor guiding projection 12 in the process of mounting clip ill on wall t5 and by a portion 4! of reduced wall thickness for engagement between resilient projection l2 and wall I5.

It is noted further that the openings l3, M on the one hand and openings 21 and 28 on the other hand are spacedvapart a distance slightly less than the distance between the ends of projections II and I2.

While particular embodiments of the present 1 invention have been shown and described, it will shaped.

tially perpendicular to the plane ofsaid thin sheet member and the horizontal portion of the L extending substantially parallel to the plane of said sheet member inadirection opposite to the direction in which .said resilient projection extends. v 2. In a clasp supporting arrangement a thin sheet member having integrally formed thereon a pair of oppositely extending projections, one of said projections being resilient and extending from a point intermediatethe ends of said member on one side'thereof at an'acuteangle therewith in the direction of, one end'of said member, the other projection extending from saidone side at the other end of said member and being hook shaped, said one projection being integrally formed withsaid sheet memberandforming therewith a resilient clamp whereby said sheet member may be clamped resiliently and releasably to a supporting wallor the like.

4. The combination of a clasp supporting member with an apertured support havin an inner and an outer wall surface, said clasp supporting 1 member being of thin sheet material andhaving integrally formed thereon a pair of oppositely extending projections, one of saidprojections being resilient and extending from a point intermediate the ends. of said member on one side thereof at an acute angle therewith in the direction of one end of said member, the other projection extending from said one side at the Other end of saidmember and being L -shaped with the vertical portion of the L extending substantially perpendicular to the plane of said. thin sheet member and the horizontal portion of the Lextending substantially. parallel to the plane of said sheet member in a direction opposite to thedirection in-which said resilient projection extends, said support having a pair of apertures spaced a distance slightly less than the distance betweentheends of said projections, oneof said apertures having its opening area and shape slightly greater than the projected area and shape of said horizontal portion ofsaidL and the other one ofsaid-apertures having its opening area and shape slightly greater than the projected ,area ofsaid resilient projection, said'acutqangle and the wall thickness of said apertured support and the other one of said apertures having its being so dimensioned that insertion of said resilient projection through its corresponding opening from the outer wall of said support to engagement with the inner wall of said support results in stressing of said resilient projection, whereby said clasp supporting member may be attached to said apertured support by initially inserting the free end of said resilient projection from the outer side of said support into its corresponding opening into sliding resilient engagement with the inner wall surface of said support thereby stressing said resilient projection until said L-shaped projection comes in registry with its opening, then inserting said L-shaped projection through its corresponding opening and then moving said horizontal portion of the L into sliding engagement with said inner wall surface wherein it is held in spring biased condition due to the stressed condition of said resilient projection.

5. The combination of a clasp supporting member with an apertured support having an outer and an inner wall surface, said clasp supporting member having formed thereon a pair of projections, one of said projections being resilient and extending from one side of said member at an acute angle therewith in the direction of one end of said member to form a resilient clamping memher, the other projection extending from said one side near the other end of said member and being hook-shaped, said support having a pair of apertures spaced a distance slightly less than the distance between the ends of said projections, one of said apertures having its opening area and shape slightly greater than the projected area and shape of said hook-shaped projection opening area and shape slightly greater than the projected area of said resilient projection, said acute angle and the wall thickness of said apertured support being so dimensioned that insertion oi said resilient projection through its corresponding opening from the outer Wall of said sup.- port to engagement with the inner wall surface of said support results in stressing of said resilient projection, whereby said clasp supporting member may be attached to said apertured support by initially inserting the free end of said resilient projection from the outer side of said support into its corresponding opening into sliding resilient engagement with the inner wall surface 01 said support thereby stressing said resilient projection until said l1ook-shaped projection comes into registry with its opening, then inserting said hook-shaped projection through its corresponding aperture and then moving said hook-shaped projection into sliding engagement with said inner wall surface wherein it is held in spring biased condition due to the stressed condition of said resilient projection.
