the radio communication receiver represented in fig1 a and 1b which is a portable telephone here denoted device in the following text comprises a main body 1 with an antenna 2 for receiving ( or transmitting ) radio waves from ( to ) a transmitter which is not shown . the device also includes a support mechanism 3 which is formed by a clip 4 and a tilting member 5 . the clip 4 is of a known type similar to that of a cap of a fountain pen except for the fact that its width in proportion to that of the device is larger . the clip 4 made of an elastic material is fixed by its upper end 6 to the top of the back face of the receiver . the clip may be fixed for example by means of a screw , or by a possible insertion into a casing of the body 1 provided for this purpose . the second end 7 of the clip 4 which presses against the body 1 in a state of rest is elastically movable and comprises a shaft 8 which passes through one end of the tilting member 5 . the tilting member 5 may pivot around the shaft 8 between a folded position represented in fig1 a wherein it coincides with the clip 4 and a completely unfolded position such as represented in dotted lines in fig1 b . the added lengths of the clip 4 and of the member 5 are such that the device is in upright position , fig1 b , on a horizontal plane 9 in a direction close to the vertical , there being provided that the device is supported by a lower stop and the second end 18 of the member 5 , while these two segments form a trapezium ( not shown ) inside which the vertical projection of the center of gravity of the device is found . it will be noted that in this substantially vertical position the device is easy to fetch in the present state and then put it back in the same position on a table . for that matter , it will be noted that because the battery of the device is placed in the lower part , the center of gravity of the device is advantageously situated lower than the shaft 8 . in fig1 b are also represented in broken lines other rotational positions of the member 5 around the shaft 8 which make it possible to obtain , for example , inclinations of 75 , 52 , 41 °. in the position of fig1 a , the receiver may be clipped in known fashion to a coat pocket or shirt pocket or also to a belt or a swimsuit . a support mechanism for a receiver as shown in fig1 a and 1b is represented in fig2 . the actual clip 4 is formed by a fork having two prongs between which there is a space in the form of an interstice 11 which ends at its upper part in a bell - shaped portion 12 . the tilting member in the form of a tab 5 is designed to fill the space 11 in folded position , except for the bell - shaped portion 12 . preferably , the clip and the tilting member are made of a thermoplastic resin , of polyamide such as nylon or rilsan or polypropylene which gives them a slight elasticity and a large robustness with their thickness of the order of 2 to 3 mm . clip and tilting member may be obtained by hot injection molding . the shaft 8 which is coupled to the parts 4 and 5 is preferably made of metal ; of steel , for example . at one end it may have a head 13 . for mounting the mechanism , the shaft 8 is driven with a slight force through the free end of the first prong of the clip 4 then through one end of the tilting member 5 and through the end of the other prong of the clip 4 until the head 13 is in contact with the first prong and the other end 14 ends up on the outside of the second prong . the mounting is completed by riveting the end 14 of the shaft , which creates a slight flare of the end 14 . this ensures a slight allowance between the parts 4 and 5 and thwarts the shaft 8 to leave its housing . for obtaining the various positions of the support member represented in fig1 a and 1b , there may be provided that the allowance between the parts 8 and 4 , 5 on the one hand and the allowance between the parts 4 and 5 on the other is sufficiently small to maintain the device in stable manner with the inclinations that correspond to these positions , the mutual frictional forces between the elements 8 , 4 and 5 being clearly higher than the weight of the device . however , to mitigate a possible reduction of the frictional forces with time and use , the embodiment of fig3 a and 3b is preferred which represents enlargements of the parts referenced a and b in fig2 . in fig3 a the side face 15 of one prong of the clip 4 has surface irregularities 16 which are either recesses or ridges respectively , regularly arranged in a circle around the hole for the shaft 8 . in a manner not shown the member 5 has opposite complementary surface irregularities on its side face after being mounted , that is to say , ridges or recesses which correspond , for example , to 30 degrees of rotation from each other ( 12 surface irregularities around the shaft ) for providing as many stable positions for the device . this arrangement may be provided on one side of the tilting member and the prong or , preferably , on two sides . in fig3 b is shown a similar arrangement to that of fig3 a to ensure a slight locking of the member against the clip in folded position of the member , while this locking may already have been ensured by the device shown in fig3 a . the side face 15 has on or in its upper part a ridge or a recess 17 intended to cooperate with a complementary recess or ridge of the member 5 situated opposite thereto , when the latter fills the space formed by the opening 11 . in the latter position , the movable end of the tilting member referenced 18 in the fig1 a - 1b fits in the bell - shaped opening 12 while leaving a small recess . this recess is used for putting a finger or a nail in to catch the end 18 of the member 5 so as to make it pivot around the shaft 8 and place it in one of the positions represented notably in fig1 b . while examining the fig2 and 3b , it may be noted that the recessed part 12 reveals a substantially circular form . this form may be benefitted from to form a button hole 19 which is represented in fig4 . in this figure is shown in a broken line the end 18 of the member 5 accommodated in the opening 11 and which has a slightly concave form to fill up the circular form of the recessed part 12 . a button 21 which may be fixed by any known means to a belt ( not shown ) is provided to be sunken into the recessed part 12 after which the support 22 of the button 21 engages with an extended recess referenced 23 at the top of the opening 11 beyond recessed part 12 so as to catch the button 21 between the clip and the body 1 of the device . it will be noted that the recessed part 12 and the button hole 19 could be separate , the button hole then being placed highest in the clip near the end 6 at which the clip is fastened to the body 1 of the device . openings such as 12 or 19 locally diminish the width of the prongs of the clip 4 which may render the clip more fragile and at any rate too elastic at this spot . for compensating this fragility , the prongs of the clip may locally be thickened at the spot of the functional recess ( es ) of the clip 4 , as shown in fig5 where a reinforcement 25 may be noted at the level of the flare 12 of the opening 11 . the invention is not restricted to the example described above . the clip could notably comprise only a single branch in which case the support member would be put beside it in folded position and the recessed part 12 would no longer be necessary .
