SHEET 1 [1F 2 HI INN] i PAGING RECEIVER CIRCUITS- K DECODERS- ALERTING SIGNAL GENERATOR m! I m SHOLLY KAGAN RQSEN & slemnummim VilBlllATOlkY ALERTING DlE /llClES BACKGROUND OF THE INVENTlON This invention relates to vibratory alerting devices, for example to paging receivers of the kind which can be carried on the person of a user. Customarily, such receivers are small enough to fit into a shirt pocket, or to be clipped to the belt holding up a persons trousers.
Paging receivers are now in use employing an audible alerting signal. This has disadvantages when the user wants to avoid alerting or disturbing other persons. Substitution or addition of a visual alerting signal (e.g. a flashing light) does not entirely solve the problem, for the attention ofthe user cannot always be assured, nor can the user be certain to avoid alerting other persons. The present invention solves the problem with an alerting device employing an invisible vibratory alerting signal, which has unique advantages not afforded by audible or visible alerting signals.
According to the present invention a rigid supporting structure, which contains or supports means (eg. radio receiver) to provide an alerting signal, has affixed to it normally inactive vibrator means constrained to be movable only in a substantially linear path relative to the structure, and employs the alerting signal to activate the vibrator means. When the vibrator means is activated the entire structure is set into forced vibration in unison with the vibrator means, and if it is being carried on the person ofa user only the user feels the vibration and, therefore, only the user is alerted to the calling signal.
A feature of the invention is that the alerting signal may be provided by a battery-operated radio receiver, and battery can simultaneously be used as the vibrator means. In Lsuch a case, the battery holder is used to constrain the battery to be movable only in a linear path, and when activated it is caused to oscillate in that path against a resilient member, such as a spring. An independent oscillatable mass can otherwise be used. Another feature of the invention is that a linearly oscil- Iatable link can be used to rock a pocket clip about a hinge attachment to the supporting structure, so that the entire structure is oscillated relative to a person wearing it.
Several embodiments of the invention are described in this specification, illustrating a variety of preferred ways to practice the invention. The description, which follows, refers to the accompanying drawings, in which:
FIG. 1 shows two external views, A and B, of a paging receiver according to the invention;
FIG. 2 is a partly sectional schematic illustration showing the location of parts in FIG. l;
FIG. 3 is a fractional sectional view of another embodiment of the invention;
H0. 4 is a partial section along line d-d in FIG. 3; and
FIG. 5 schematically illustrates a partial end section of another embodiment of the invention.
Referring now to FIGS. llA and B and FIG. 2, the alerting device is a paging receiver, comprising a rigid supporting structure ll] (FIG. 2) which supports within its framework lit the prior art electronic and electromechanical components 12 which perform the radio receiver, filter and decoder, and alerting signal generator functions. Since these are prior art components, they will not be described. Also supported in the structure iii are a power source (i.e., battery) l3 and an antenna M. The top part id of the structure lit) is also an outer part of the housing of the receiver, and contains a phone jack l6, and a vibrator means l7. As is shown in FIG. 1A and B, a cover 118 fits slidably over the frameworklll to enclose the parts l2, l3 supported in it, and completes the outer housing of the receiver. A clip l9 hinged to the cover 16 is spring urged as by a spring 21 to hold the receiver in a pocket or to a belt (not shown).
The vibrator means 117 may, as shown in FlG. 2, comprise an electric motor 22 having a rotatable shaft 23 with an end cam 2- 5 on it. A cover l7.ll covers the motor 22, and a pair of wires 25 which carry the alerting signal from the alerting signal generator in the parts 12 to the motor 22 are connected to the motor under this cover. The motor is normally at rest; that is, inactive; and it is activated, that is, caused to spin the shaft 23, when the alerting signal is applied to it. A cam follower 26 engages the end cam and follows the cam in directions parallel to the axis of the shaft 23. The cam follower includes a contactor 27 for one electrode (the positive electrode as illustrated) at one end of the battery l3, which also fits piston fashion into one end of the battery compartment 28. The other electrode at the other end of the battery is contacted by a spring 29 which in turn makes negative electrode contact to the framework ii. A wire 30 connects the cam follower 26 to the parts 12, and the follower is obviously electrically conductive so that the battery can provide electric energy to the parts l2. A second wire 3 connects the parts B2 to the framework ill. The cam follower causes the battery 13 to vibrate in a linear path against the spring 113 at a frequency determined by the speed of rotation of the motor 22. As is taught in my copending application, Ser. No. 766,781 filed Oct. II, 1968, a low frequency of vibration, below audible, such as 5 cycles per second, may be advantageously used. The walls of the compartment 2% constrain the battery to be movable only in a substantially linear path relative to the structure it), or the framework ii. The battery forces the structure to vibrate in unison with it when the motor 22 is activated, and thus functions as not only the source of electric energy for the receiver, but also the mass of the alerting vibrator means 117. The motor 22 is rigidly engaged with the top part of the structure It); for example, the top part may be of a plastic material and the motor 22 press fitted into a bore l5]! in the top part.
H65. 3 and A show an alternative form of linear vibrator employing a mass 40, other than the battery, in a housing Al. The mass is a plate of flat material having projections 42 on opposite edges 43 for engaging grooves. 414 in walls lS of the housing ll, so that the mass can slide back and forth in these grooves, in the housing. The mass is thereby constrained to be movable only in a substantially linear path relative to the structure it). A motor 46 is mounted on a backwall 417 of the framework 11 (see FIG. d) and its shaft All drives an eccentric cam 49 in a yoke 50 in the form of an aperture in the plate A0; a yoke or positive-motion cam is thus provided linking the plate 40 with the motor 46. The motor thereby drives the plate 40 back and forth, as illustrated by the doubled-headed arrow 51, when the motor is activated. it will be understood that the motor 46 may be connected to electrical circuits in the same manner as the motor 22in H6. 2.
in FIG. 5 a clothespinlike clip 60, for attaching to the pocket or other part of the clothing ofa person, is connected near one end 611 via a hinge 62 to the top part l5 of the structure it). A spring 63 located between the end portion 61 and the top part 15, beyond the hinge, biases the clip so that the second end 64 is urged toward the structure it). As illustrated, the cover T8 (not shown) is removed and the framework it is exposed. A motor 70 mounted in the framework is fitted with an end cam 7i, and a push rod 72, engaged at one end in the clip near the second end 64 extends to the cam surface to function as a cam follower. When the motor is activated the clip is caused to oscillate about the axis of the hinge 62, against the spring 63, by the linear oscillation imposed upon the push rod 72 by the end cam 7i. The push rod is constrained to execute motion in a linear path. A hole (not shown) may be provided in the cover iii (shown in FIG. l.) for passage of the push rod 72 when the cover is in place on the embodiment of FIG. 5. To install or remove the cover it is necessary only to lift the second end 64 of the clip 66 away from the framework ll far enough so that the cover can pass by the free end of the push rod.
