- ABSTRACT A self-latching security device for public coinoperated telephones includes spring-Biased latch pins which replace security mounting screws to simplify installation of such telephones with requisite security against theft of the telephone or the coin collection box of the telephone.
- the present invention relates generally to the installation of public, coin-operated telephones and pertains, more specifically, to a self-latching security device which enables simplified installation of such telephones with the requisite security against theft of the telephone or the coins collected therein.
- Another object of the invention is to provide a security device which can be installed in present telephone housings without modification of the housings.
- a further object of the invention is to provide a security device which can be installed at the factory, enabling the coin compartment of the telephone to be locked at the factory and eliminating the need for a coin collector at the installation site.
- a still further object of the invention is to provide a security device which is simple in design and construction and easily installed for virtually fool-proof operation.
- a telephone housing having at least one aperture therein communicating with the interior and exterior thereof at a predetermined location in the housing and a coin compartment therein which is lockable to close-off access to the aperture through the interior of the housing, is secured to a mounting board by fasteners which are affixed to the housing, extend longitudinally to enter the mounting board, and secure the housing thereto upon relative lateral movement between the housing and the mounting board, the mounting board having an opening at a position corresponding to the location of the aperture in the housing when the housing is secured by the fasteners to themounting board, a self-latching security device comprising at least one latch pin, and means for mounting the latch pin within the aperture of the housing for resilient deflection between an advanced position wherein the latch pin extends longitudinally from the housing for entering the corresponding opening in the mounting board, and a retracted position wherein the latch pin is

- FIG. 6 is a cross-sectional view taken along line 66 of FIG. 5;
- FIGS. 7, 8 and 9 are side elevational views of the telephone housing and mounting board, illustrating various stages of installation of the telephone housing with the security device.
- Housing 10 has a back wall 12 within which there are a plurality of upper apertures 14 and lower apertures 16.
- a coin compartment 18 is located in front of the back wall 12 and receives a coin collection box 20 which, by means of a cover plate 21 which carries a lock 22, can be locked in place within the coin compartment 18.
- cover plate 21 which carries a lock 22
- access to the lower apertures 16 is closed off.
- Housing 10 is to be installed upon a mounting board 24 which is a part of a fixed installation at the site of the installation.
- Mounting board 24 has a plurality of upper openings 26, corresponding in location to upper apertures 14, and lower openings 28, corresponding in location to lower apertures 16.
- Upper openings 26 have a slotted, key-hole" configuration including an enlarged upper portion 30 and a narrower lower portion 32.
- Fasteners in the form of step-bolts 34 are affixed in upper apertures 14 and project longitudinally outwardly from the back of the housing 10, each step-bolt 34 having a head 36 complementary to upper portion 30 of anopening 26 and a shoulder 38 complementary to lower portion 32.
- housing 10 would be installed upon mounting board 24 in the presence of two men; namely, a telephone installer and a coin collector.
- the installer would place the housing 10 against the mounting board 24, with the heads 36 of the step-bolts 34 passing longitudinally through corresponding upper portions 30 of openings 26 and then would move the housing 10 laterally downwardly relative to the mounting board 24 to pass shoulders 38 into lower portions 32, whereby the heads 36 of the step-bolts 34 would secure the housing against the mounting board 24.
- the installer would insert security screws (not shown) through lower apertures 16 into lower openings 28 to secure the housing 10 against lateral movement relative to the mounting board 24, thereby precluding removal of the housing from the mounting board without removal of the security screws.
- Access to the coin compartment 18, and hence to the security screws is closed off by the placement and locking of the coin collection box 20 in the coin compartment by the coin collector. For security reasons, the installer is not provided with a key to the coin compartment.
- the security device of the present invention enables the telephone housing 10 to be installed upon mounting board 24 without access to the coin compartment 18, yet with essentially the same measure of security.
- the coin collection box 20 may be placed within the coin compartment and locked in place in the factory. Since removal of the coin collection box is not required for installation of the housing 10 an installer can accomplish essentially the same secure installation without the presence of a coin collector. Savings in labor costs are thus realized.
- Security device 40 includes a body 42 constructed of a resiliently deflectable material such as spring steel, the body having opposite, essentially flat arms 44 terminating in opposite ends 46.
- a latch pin 48 is affixed to each arm 44 adjacent the end 46 thereof and projects generally perpendicular to the flat surface of the arm.
- tongue 50 extends downwardly, intermediate the ends 46 and carries a tab 52.
- housing 10 is provided with a plate 60 affixed to the inside of the back wall 12 of the housing, as by welding.
- Plate 60 includes a portion 62 spaced from the back wall 12 and having a hole 64 passing through portion 62, but not through the back wall.
- hole 64 is a blind hole in that access to the hole is gained only from the interior of the housing 10.
- a slot 66 is located in portion 62 of the plate 60, immediately below hole 64.
- Security device 40 is installed in housing 10 in the factory, before the coin collection box 20 is put in place, by locating the bushing 54 in hole 64, as seen in FIGS. 3 through 6.
- Bushing 54 and hole 64 are complementary in dimensions and configuration sothat the bushing is seated in the hole.
- the relative location of the bushing 54 and latch pins 48 is such that upon seating of the bushing in hole 64, latch pins 48 will enter lower apertures 16 and will project longitudinally from the back wall 12 of the housing 10, as seen in FIG. 7.
- tab 52 will be inserted into slot 66, as seen in FIGS. 3 and 4, and the eccentric 56 will be located adjacent the rear surface 68 of plate portion 62, surface 68 being the surface opposite to front surface 70, against which body 42 rests.
- Shaft 58 which carries the eccentric 56 at one end thereof, also carries a slotted head 72 which can be turned to rotate the shaft and move the eccentric between a first position, illustrated in FIG. 4, and a second position, illustrated in FIG. 6. In the first position,
- the eccentric 56 is aligned with the bushing 54 so that the eccentric can be passed through hole 64. Turning the slotted head 72 through a half-turn will rotate the eccentric 56 into the second position wherein the portion 62 of plate is clamped between the eccentric and the body 42 so that the body is locked in place in the housing 10.
- a visual indication of the position of the eccentric is provided by the word LOCK, as seen in FIGS. 3 and 5.
- the L is aligned with the OCK, as seen in FIG. 5, the eccentric is in the locking position illustrated in FIG. 6.
- means are pro-, vided for anchoring the body in place within the housing with the latch pins 48 mounted within lower apertures 16 so as to project from the back wall 12 of housing 10.
- FIGS. 7 through 9 an installer in the field follows a procedure similar to the initial steps of the current conventional installation procedure.
- the housing 10 is brought toward the mounting board 24 with the heads 36 of the step-bolts 34 aligned longitudinally with the upper portions 30 of upper openings 26 in the mounting board 24.
- the latch pins 48 in this position, are not aligned with the lower openings 28 of the mounting board.
- the housing 10 is then pushed against the mounting board 24, thereby passing the heads 36 of the stepbolts 34 through the upper portions 30 of upper openings 26. Because the latch pins 48 are not aligned with lower openings 28, the latch pins will abut the mounting board and will be deflected as the housing moves against the mounting board.
- the resilient property of the material of body 42 of security device 40 enables the body to serve as a leaf spring allowing resilient deflection of arms 44 and permitting the latch pins 48 to be retracted from the advanced position illustrated in FIG. 7 to the retracted position illustrated in FIG. 8.
- the security device 40 cannot be rendered ineffective prior to installation by attempts to force retraction of latch pins 48 beyond the retracted position and then to rotate the body 42 about the bushing 54. Such rotation is precluded by the engagement of tab 52 within slot 66.
- housing 10 upon mounting board 24 is accomplished by an installer without the presence of a coin collector and without a key to the coin compartment 18 since security device 40 is selflatching and access to the security device 40 by the installer is not required. Hence, the desired degree of security is attained.
- the coin compartment 18 is opened with the appropriate key, the coin box 20 is removed and access is gained to security device 40.
- the slotted head 72 need merely be rotated through a half-turn to unlock the eccentric 56 by aligning the eccentric with the bushing 54.
- the entire security device 40 may then be withdrawn from the back wall 12 of the housing, thereby retracting the latch pins 48 from the lower openings 28 and permitting removal of the housing 10 from the mounting board 24.
- a self-latching security device comprising:
- the latch pin means for mounting the latch pin within the aperture of the housing for resilient deflection between an advanced position wherein the latch pin extends longitudinally from the housing for entering the corresponding opening in the mounting board, and a retracted position wherein the latch pin is retracted from said opening, with said mounting means resiliently biasing the latch pin toward the advanced position whereby the latch pin will be deflected to the retracted position by contact with the mounting board until relative lateral movement between the housing and the mounting board aligns the aperture with the opening to permit advancement of the latch pin to the advanced position and concomitant locking of the housing against further lateral movement relative to the mounting board.
- said mounting means include:
- anchoring means for securing the leaf spring to the housing
- said latch pin being affixed to the leaf spring and said anchoring means being located remote from the latch pin.
- the housing includes a wall, a plate within the interior of the housing and having a portion spaced from the wall so as to lie between the wall and the coin compartment, and a hole passing through said portion of the plate, said anchoring means including:
- said self-latching security device includes:
- said mounting means include a leaf spring having opposite ends, one of said latch pins being affixed adjacent each of the opposite ends of the leaf spring;
- anchoring means mounted upon the leaf spring intermediate said opposite ends for securing the leaf spring to the housing.
- the housing includes a wall, a plate within the interior of the housing and having a portion spaced from the wall so as to lie between the wall and the coin compartment, and a hole passing through said portion of the plate, said anchoring means including:
- the housing includes a wall, a plate within the interior of the housing and having a portion spaced from the wall so as to lie between the wall and the coin compartment, and a hole passing through said portion of the plate, said anchoring means including:
- an eccentric positioned relative to said bushing such that the eccentric will be located between said portion of the plate and the wall upon seating of the bushing in the hole, said eccentric being mounted for rotation in the bushing between a first position wherein the eccentric is aligned with the bushing for insertion into the hole and a second position wherein the eccentric projects radially relative to the bushing to enable clamping of said portion of the plate between the leaf spring and the eccentric.
- the invention of claim 8 including means for rotating the eccentric between the first and second positions in the housing.
