Description:
BACKGROUND OF THE INVENTION 
     This invention relates, in general, to security devices, and, in particular, to a security device for a lap top computer 
     DESCRIPTION OF THE PRIOR ART 
     In the prior art various types of security devices have been proposed. For example, U.S. Pat. No. 5,757,616 to May et al discloses a locking bar for locking a display and system unit together. The device also prevents removal of peripheral devices and disables input from the keyboard and mouse. 
     U.S. Pat. No. 5,709,110 to Greenfield et al discloses a lap top security system comprising mounting plate affixed to the monitor housing and a cable which attaches to a table or counter top. 
     U.S. Pat. No. 5,787,738 to Brandt et al discloses a security lock for a computer comprising a blade which passes through the gap between the monitor and keyboard and which is fastened to a fixed object. 
     U.S. Pat. No. 5,595,074 to Munro discloses a desktop security locking station comprising a box and a clamping mechanism for securing the box to the computer. The box is then secured to a table top. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to a lap top security device which has two adjustable arms and two fixed arms which engage with a lock and which adjust to fit different size computers to lock the computer closed. In addition one of the fixed arms has a loop so the security device can be attached to a fixed object. 
     It is an object of the present invention to provide a new and improved computer security device. 
     It is an object of the present invention to provide a new and improved computer security device which will secure a lap top computer in a closed position. 
     It is an object of the present invention to provide a new and improved computer security device which has provisions to secure the security device to a fixed object. 
     These and other objects and advantages of the present invention will be fully apparent from the following description, when taken in connection with the annexed drawings. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a top view of the present invention attached to a lap top computer. 
     FIG. 2 is a bottom view of the present invention attached to a lap top computer. 
     FIG. 3 is a top view of the locking device of the present invention. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings in greater detail, FIG. 1 shows the locking device  1  of the present invention as it would be attached to a lap top computer, as seen from the top  2  of the computer. The locking device, as more clearly seen in FIG. 3, comprises four arms  4 ,  5 ,  6 ,  7  which slide into a lock casing  3  and are lockingly retained therein. It should be noted that the arms  4 ,  5 ,  6 ,  7  as shown in FIG. 3 are turned 90° from their operating position for clarity. 
     As seen in FIG. 1, the arm  4  is offset slightly from the arm  6 , which is directly opposite arm  4 . Likewise, arm  5  is offset slightly from the arm  7  which is directly opposite arm  5 , in order to prevent any interference between the arms as they enter the lock casing  3 . Also, arms  4  and  6  will be offset slightly from the arms  5  and  7  for the same reason. 
     The lock casing  3  is a conventional lock having a top, bottom and a plurality of sides with the arms extending from the sides which has projections inside which will engage the grooves  13  on the arms  4 ,  5 ,  6 ,  7  and hold the arms within the casing  3 , therefore, no further description of the lock casing is necessary. The lock casing can have an aperture  14  to receive a key for unlocking the arms  4 ,  5 ,  6 ,  7  so they can be disengaged from the casing  3 . It should be noted that it is not critical that the key hole  14  be on the top of the lock casing in order to work. It could also be placed on one of the sides of the lock casing  3 . 
     As shown in FIGS. 1 and 2, when the lap top computer is closed, the security device of the present invention can be secured to the closed lap top by positioning the arms  4 ,  5 ,  6 ,  7  as shown and sliding the arms into the lock casing  3  where they will be secured against removal. The hook portions  8  of the arms will engage beneath the lap top, and will prevent any one, without a key from opening the lap top. Therefore, even if a thief takes the lap top they will be unable to open and use it. This will make it undesirable for someone to take the lap top. Also, securing the lap top in this manner will prevent anyone from accessing any information stored on the lap top. 
     As shown in FIGS. 2 and 3, at least one of the arms has a loop  9  attached thereto. As shown in FIG. 2, this loop, along with a cable  11  and a lock  12  can be used to secure the lap top  2 ,  3  to a fixed object, such as a desk, by looping the cable around a portion of the desk and securing it by means of the lock  12 . This will increase the security of the lap top. 
     Although the Lap Top Lock and the method of using the same according to the present invention has been described in the foregoing specification with considerable details, it is to be understood that modifications may be made to the invention which do not exceed the scope of the appended claims and modified forms of the present invention done by others skilled in the art to which the invention pertains will be considered infringements of this invention when those modified forms fall within the claimed scope of this invention.
