Description

BACKGROUND OF THE INVENTION

This invention relates to security devices and more particularly for a security device for facsimile machines.

Security officials for departments of the government, companies, and the like have generally been concerned about the security of information sent and received through facsimile machines as facsimile or fax machines have become an integral part of sending and receiving information in every day business. The reason for the concern is that fax machines are generally located in secretarial or administrative areas of an office and usually are kept on at all times since many messages are received by the fax machines after working hours. Thus, major security concern arises when a fax containing sensitive information is received during these non-business hours. These communicating papers known as faxes sit on the machines during these non-business hours and are available to cleaning personnel, contractors, and even employees who may not be authorized to receive the particular information on the faxes. Moreover, the faxes received during the non-business hours can easily be stolen, copied or read without the knowledge of the sender or receiver of the fax transmission.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a security device for fax communications received by a facsimile machine.

Another object of this invention is to provide a security device for receipt of fax transmissions during non-business hours.

A further object of the present invention is to provide a security device for a fax machine which is relatively inexpensive and easy to operate.

Particularly, the present invention provides a security device for a facsimile machine comprising: a base member, a cover, and a locking bar engageable with the base member and the cover with a fax machine covered by the cover in a secured position. More particularly, the base member is provided with alternating tongue and groove sections along opposed sides of the base member in mating relation with alternating tongue and groove sections of the cover and the locking bar is provided with movable locking means engageable with channels or grooves in selected portions of said tongues of said base member and said cover.

Further objects and advantages of this invention will become apparent from the following description and appended claims, reference being had to the accompanying drawings forming a part of the specification wherein like reference characters designate corresponding parts into several views.

DESCRIPTION OF THE PREFERRED EMBODIMENT

As best shown in FIG. 1, a security device of the present invention is comprised of a cover 10, base member 14 and a U-shaped locking bar 12. The cover 10 is provided with alternating tongues 16 and grooves 34 along its lower terminating edge on opposed sides in mating relation with alternating tongues 36 and grooves 18 on opposed sides of the base member 14. The tongues 16 are provided with elongated through-bores 20 therethrough for receiving L-shaped arm portions 26 of the locking bar 12. The base member 14 is also provided with means to receive the L-shaped arms 26 and as shown in FIG. 1 the means to receive L-shaped arms 26 are channel-shaped portions 24 extending longitudinally from one end of tongues 22 a distance less than the width of the tongues 22.

The U-shaped locking bar 12 is also provided with a prior art key operated lock 28 and a movable latch member 32 operable in response to movement of a key (not shown) within the lock 28. Base member 14 is provided with a slot 30 therein to receive the movable latch member 32.

Also as shown in FIG. 1, the base member 14 is provided with a blower 40 which is actuated in response to switch 46 when the cover 10 is positioned onto the base member 46, a tab 48 (FIG. 4) engages the switch 46 and the fan 40 is energized. Moreover, an air vent 38 is also included in the cover 10 to provide an outlet for the air generated within the security device by the blower 40.

As shown in FIG. 2, the cover 10 is placed in a secured position over the facsimile machine shown in phantom lines. Moreover, the mating relationship between the tongue and groove portions of the cover 10 and the base member 14 are also shown.

As best shown in FIGS. 3 and 4, the back of the cover 10 is provided with a slot 44 therein which is used for easy access of electrical supply means to the fax machine when sealed under the cover 10. Moreover, as best shown in FIG. 4, the cover 10 is provided with the inwardly extending tab member 48 which is engageable with the switch 46 when the cover 10 is positioned onto the base member 14. The switch 46 closes the circuit to the blower for the blower 40. Moreover, as shown, a blower plug 42 is also provided for supplying the electrical energy to the blower motor.

As shown in FIG. 5, the cover 10 is placed securely upon the base member 14 wherein L-shaped engaging arms 26 of the latching bar 12 are partially received within the channels 24 of the base member 14 and the through-bores 20 of the tongues 16 of the cover 10.

As shown in Fig. 5A, cover 10 is removed and the L-shaped locking arms 26 are recessed further into the channels 24 so that the cover 10 and particularly the tongue portions 16 are no longer engaged by the L-shaped latching arms 26.

In the operation of the security device of the present invention, the base member 14 is placed upon a table, desk or the like upon which a fax machine is to be located. The fax machine is placed upon the base member 14 and used under normal operating conditions. The U-shaped latching bar 12 is placed upon the base member and the L-shaped latching arms 26 are positioned within the channels 24 as shown in FIG. 5A thereby leaving the grooved portions 18 unobstructed. At the end of the business day or at other times when an appropriate attendant is not available for the fax machine, the cover 10 is then placed onto the base member 14 with the tongues and grooves 16 and 34 of cover 10 being placed in mating relation with the tongues and grooves 22 and 18 of the base member 14. The U-shaped locking bar 12 is then pushed rearwardly so that the L-shaped arm 26 engages with the through-bores 20. With each locking arm 26 being held within a channel 24 of the base member 14 and an aligned through-bore 20 of the cover 10, the cover 10 is secured to the base member 14 thereby enclosing the fax machine. A key is then inserted into the lock 28 whereby the movable latch portion 32 engages with the slot 30 and the cover 10 is secured to the base member 14.

In the construction of a security device of the present invention, the cover 10 is generally made of a material which is non-transparent. For example, one preferred cover is made of a smoked plexiglass or other colored plastic material whereby the fax transmissions received on the fax machine are not reachable through the cover. Base member 14 may also be made of a hard plastic material and the U-shaped locking bar is generally made of a hard plastic or mild steel.

It is realized that various changes in the details, materials of construction, steps and arrangement of parts which have been described herein and shown in the drawings in order to explain the nature of the invention, may be made by those skilled in the art without departing from the principals and scope of the invention as expressed in the claims appended hereto.
