. 29 Claims.

This inventionrelates-to mountings for acoustic devices and more particularly to mountings for handset telephones adapted "to be-supported on a vertical surface.

One object of the invention is to provide a mounting unit-for a handset telephone which will enable easy removal of the handset from the mounting by the user thereof while preventing accidental removal therefrom under extraordinary adverse conditions.

Another object of the invention is to provide a mounting unit for ahandset telephone which will maintain the handset in position on the mounting unit under severe conditions such as encountered at battle stations or in gun turrets of fighting units in actual combat.

It is a further object of the invention to provide a mounting unit of the type described which is extremely rugged in construction and which embodies a new and improved arrangement for facilitating replacing and removing of the handset telephone from the mounting unit.

The foregoing objects and features thereof will be described hereinafter with reference to the accompanying drawings, in which:

Fig. 1 is a front view of the mounting unit with the telephonehandset omitted in order to more clearly illustrate the interior of the mounting unit;

Fig. 4 is a cross-sectional view of the mounting unit illustrated in Fig. 1 taken along line 4-4 thereof with the handset unit mounted thereon as is illustrated in Fig. 2, and also shown in section; t

Fig. is a cross-sectional view of the mounting unit illustrated in Fig. ltaken along line 5-5 thereof with the handset 'unit mounted thereon asillustrated in Fig. 2, .and also shown in section.

Referringnow to the drawings, there isshown a mounting unit or support illustrative of this invention, for 'a telephonehandset 32, which mounting unit comprises a supporting base plate 6 and a casing or well-shaped member generally indicatedas 1 which is preferably made of cast brass formed inthe shape indicated to conform.

with the general contour of the handset "32. .A plurality of ,mounting holes .36 are .providedIin the base plate 6 forv securing the mounting ,unit to a vertical wall or support notshown. The casing 1 is securely fastened to the base plate 6 by means of a plurality of screws 8 threaded into the casing I and comprises two parallel side wall portions -S'and i0 (Fig. 1), an upper curved wall portion H joining the two parallel sides, and a lower curved wall portion l2 joining the parallel sides, thereby forming a cavity portion within the confines of thecasing.

The upper curved wall portion ll continues outwardly away from the base plate 6 and converges into an inverted cup-shaped member l3 provided with two shoulder portions l4 and I5 joined by a bridge portion I6 thus forming a receiver receptacle. Shoulder portions l4 and I5 are formed or moulded to fit the general contour of the receiver end I! of the telephone handset 32 as is shown in Fig. 4, to thereby provide retaining members for the receiver end of handset 32 when it is in place in the mounting unit. The bridge-shaped'member 16 is slightly raised from the general contour of the inverted cup-shaped member 13, between the shoulders I4 and 15, to provide sufficient clearance for the raisedpart of the handle portion where it joins the receiver end I! of the telephone handset 32 when it is removed from or inserted in place upon the mounting unit in the manner shown in Fig. 3.

The lower curved wall portion I2 also continues outwardly from the base plate 6 and con verges into anupright c p-shaped member l8 provided with two shoulder portions l9 and forming a transmitter receptacle. Shoulderportions I9 and 20 are formed or moulded to fit the general contour of the transmitter end 2| of the telephone handset 32, as is shown in Fig. 5, to thereby provide the retaining members for the transmitter end of the handset ,32 when it is placed in the mounting unit. The central portion of the upright cup-shaped member l8 between the shoulders 19 and 20'has been left open to permit the coupling unit 23 and the cord 24, which extend from the transmitter end of the handset 3 2, to protrude through the rather close fitting shoulder portions [9 and 20 of the upright cup-shaped mfi ber I8.

Referring to Fig.2, thespring member 24 and th L-shaped stop-bracket 2,5, are secured to the supporting base 6 by means of a plurality of screws .35 threaded into the base 8, Upper portion26 of the spring member 24is tensioned outwardly away from base 6 to engage the tip end ofthe receiver cap i2! of the telephone handset 32 and the eby tends to force the receiverend l? thereof into engagement with the shoulder portions l4 and 1.5 (Fig. 4 of the invertedcup shaped member [3 when the handset is mounted in place on said mountinggunit. It should be noted that the shoulder portions l4 and 31.5, which are formed toflt the general contour of thei near surfaces of thetransmitter 17, as is shown in Fig. 4, prevent the upper portion 26 of the spring member 24 from forcing the raised part of the handle portion where it joins the re ceiver end ll of the handset 32 into the space shown in Fig. 2 between the raised handle portion and the bridge portion I6. Spring 24 at end 26 thereof, also tends to force the handset 7 v vibration of the portion 28 of the spring member 24. The spring member 24 is also bent back upon itself at 29 and extends upward and over the L- shaped end of stop bracket 25 to provide an engaging spring portion 30, which portion is tensioned away from stop member 25 to engage the mouthpiece portion 3| on the transmitter end 2| of the handset 32 and thereby tends to force the transmitter end 2| thereof into engagement with the shoulder portions I9 and 20 of the upright cup-shaped member I8 when the handset is mounted in place upon said mounting unit.

- In order to prevent the receiver end I! of the handset 32 from overcoming the tension of the upper portion 26 of the spring member 24 by inertia resulting from a severe shock or blow either on the mounting or on the handset a stop member 31 is provided which is adapted to be engaged by the receiver cap 21 of the receiver unit I I. -Ifhe stop member 31 comprises a rod 38, preferably made from screw stock material, covered by a tube 39, preferably made from a phenol fabric product, which will withstand severe shocks or blows. The stop member 31 is suitably secured between the walls 9 and I0, respectively, for example, by means of washers 33 and screws 34 passing through the wall portions 9 and ID, and threaded into the rod 38. H a

As is clearly shown in Fig. 2, the receiver end I! of the handset 32 fits into the inverted cupshaped member I3 and the rear surfaces of the receiver I'I are held into engagement with the shoulder portions I4 and I5 by means of the upper portion 26 of the spring member 24. In addition, the transmitter end 2| of the handset 32 fits into the upright cup-shaped member I3 and the rear surfaces of the transmitter 2| are held into engagement with the shoulder portions I9 and 2|] by means of the engaging spring portion 30 of the spring member 24.

. It should be understood that a force, such as caused by a bomb exploding in the vicinity of the front or rear of th mounting unit, might cause the handset unit to momentarily overcome the tension of the end portions 26 and 30 of the spring member 24 but that the extent of movement of the handset 32 is limited at the receiver end H by stop member 31 and is limited at the transmitter end 2| by stop member 25. Furthermore, the shoulder portions I4 and I5 of the inverted cup-shaped member I3 and the shoulder ,portions I9 and 20 of the upright cup-shaped member I8 prevent the handset 32 fromfbeing dislodged from the mounting unit. Although the force or explosion may be as high as 2000 foot pounds, the handset unit 32 will neither become dislodged from the mounting unit nor will any'of the parts thereof, including the handset, become broken, distorted or unusable. i Since the opening for placing the handset unit 32 upon the mounting unit and for removing the handset unit therefrom is limited by the distance between the shoulder members I4 and I5 and the shoulder members I9 and 20 and since this distance is considerably less than the overall length of the handset unit 32, the handset can only be placed upon-and removed from the mounting unit by a series of definite predetermined movements, as will be described hereinafter.

Referring now to Fig. 3, a description will be given of the placing of the handset 32 upon the 'mouhting unit.

In order to place the handset 32 upon the mounting unit the receiver end I! of the handset 32 is inserted at an angle of approximately 45 degrees into the cavity of the mounting unit formed by the upper curved wall portion II, the parallel side walls 9 and It), and the inverted cup-shaped vmember l3, above the stop member 31. After they tip end of the r eceiver cap 21 has engaged the upper portion 26 of the spring member 24 and the tension thereof has been overcome by manual pressure exerted upon the handset 32 so that the spring member 24 is flat against the base 6, as is clearly shown in Fig. 3, the transmitter end 2| of the. handset 32 is in a position to passiclea'r of the shoulders I9 and 23. Usingthe inner surfaces of the spring 26 and the uppercurved wall portion I I as and with continued manual pressure against the portion'ZB of spring 24, the transmitter end, 2| of the handset 32 1s manually rotated into the casing I until the mouthpieceportion 3| on the transmitter end of the handset 32 engages the spring portion 36 of thespring member 24 and compresses the'same. It is to be noted that during this rotation of the handset 32 in the above described movement the transmitter end 2| passes clear of the shoulder portions I9 and 20 of the upr ght cup-shaped member I8. Upon engagement with the spring portion 33 of the spring member 24, and, as manual pressure is relieved on the'receiver end I1 of the handset 32, the tension in the spring portion 3|] and that of spring portion 26 causes the mouthpiece portion 3| to slide downwardly on the slanting surface of spring 30. Thus, when the pressure is applied to the transmitter end 2|, the pressure is simultaneously released fromthe receiver end I'I of the handset 32, consequently, the tension in the upper portion 23 of the spring member 24 exerts a force upon'the tip end of the receiver cap 21 forcing the receiver end I! of the handset outwardly away from the base 6 and causes the rear surfaces of the receiver end I! to engage the shoulder portions I4 and I5 of the inverted cup-shaped membe I3. Simultaneous with the action of the upper portion 25 of the spring member 24 in'forcing the receiver end ll of the handset 32 outwardly, the pressure exerted upon the transmitter end 2| thereof on the slanting surface of the spring portion '30 together with the downward spring pressure ex-' erted on the tip of the receivercap 21 causes the transmitter end 2| to engage the lower curvewall portion I2. When the pressure on the trans mitter end 2| of the-handset 32 is removed, the tension in the spring portion 3|) forces the rear surfaces of the transmitter end 2| to engage the shoulder portions I9 shapedmember I8. The handset 32 is nowin position on th mounting unit and; cannot be dislodged therefrom even under extraordinary adverse conditions, however, the" handset 32 may be easily removed from the mounting unit by a series of movements along a predetermined path as willbe described hereinafter,

and 20 ;of the upright cup- 2,35 1,126 The handset 32 inay be easily removed rro'm be noted thatthe handset is-positioned inthe mounting unit with the transmitter end 2| thereof and the receiver end I"! engaging the shoulderp'ortions-IS and 20, and I4 and I5, respectively, under thepressure of spring portions 30 and 26, respectively. In order to remove the handset 32 from the mounting unit the handset is first moved in. a vertical direction with manual pressure applied to the receiver end I! thereof against the tension of spring 26. When the receiver cap 21 has been raised sufficiently to pass clear of the st'opmember 30, the tip end of the receiver cap, has compressed the spring portion 26 until it is fiat against the base 6. With the handset 32 raised to the maximum position, that is, with the top portion of the receiver end l1 thereof engaging the inner surface of the casing l at the upper curved wall portion II and with the spring portion 26v compressed against the inner surface of the. base 8, the transmitter end 2| of the handset 32' may be rotated about the bearings comprising the surfaces of the curved wall portion Hand the spring portionZG, and will pass clear of the shoulders I9 and 20, as is clearly shown in Fig; 3. When the handset 32 bat an angle of approximately 45 degrees with respect tothe base 6, the receiverend I 1 thereof may be removed from the cavity in the mounting unit,

While one embodiment of the invention has been disclosed, it will be understood thatvar ious modifications may be made therein which are within true spirit and scope of the invention.
