Description: OCKABLE SAFETY BOX FOR COMPUTERS Technical Field The present invention relates to a lockable safety box for a computer wherein the size of the safety box is adjustable to the size of the computer. Background and summary of the invention An increasing problem in today's computerized society is theft of the relatively small and light-weight personal computers. Not only are the personal computers valuable but they often contain information that is more valuable than the computer units themselves. Some computers contain information that is even irreplaceable should the computer be stolen. A variety of alarm solutions have been provided and developed in the past. However, one inherent drawback of all alarm systems is that they almost always must be powered with electricity and the alarms do not work properly if the electricity is cut off from the alarm unit. There is a need for a reliable device that prevents unauthorized removal of a computer from a work unit without relying on complicated alarm systems. The present invention is a lockable safety box for computers comprising a frame that has size adjustable side panels. A front rod is inserted through the front openings and has an outer end that has an opening defined therein. A back rod is inserted through the rear openings and has an outer end with an opening defined therein. A side bar has an outwardly protruding lock pin for engaging the front rod and an internal pin for engaging the back rod. The front rod and the back rod extend across the front and rear openings of the frame so that a computer disposed inside the frame may not be removed therefrom when the bars are locked together.

The components 18, 20, 22 and 24 may be assembled to form the box 10 that has an adjustable size. The component 18 may be pushed into the component 20, as shown by the arrows 144, so that the front edge 58 fits into the groove 34 of the component 18 and the back edge 38 fits into the groove 64 of the component 20. The height of the box 10 may be adjusted by sliding the component 18 toward the component 20 until the openings 36 are aligned with the openings 60 and the openings 40 are aligned with the openings 68. Similarly, the component 18 may be pushed into the component 22, as shown by the arrows 146, so that the front edge 42 is inserted into the groove 104 and the back edge 110 of the component 22 is inserted into the groove 52 of the component 18. The width of the box 10 may be adjusted by sliding the component 18 toward the component 22 until the openings 44 are aligned with the openings 108 and the openings 50 are aligned with the openings 112. In a similar way, the component 20 may be pushed into the component 24, as shown by the arrow 148, and the component 24 may be pushed into the component 22, as shown by the arrows 150, to form the rectangular shaped box 10. Because both the height and the width of the box 10 are adjustable, the size of the box 10 may be adjusted to the size of the computer to be placed inside the box. It is an important feature of the present invention to be able to adjust the size of the safety box 10 to fit the size of the computer disposed inside the safety box 10. The tighter the safety box 10 is around the computer to be protected, the harder it is to break into the computer. Fig. 3 shows a detailed view of an elongate round female rod 160 of the front rod 152. The rod 160 has a large diameter section 162 and a reduced diameter section 164 with a flat upper surface 165. The section 162 and a hole 164 defined therein that is adjacent to a short end 167 of the rod 160. The surface 165 of the section 164 has a plurality of cavities 166 defined therein. The distance between the cavities 166 may be about 14 millimeters or any other suitable distance. As best shown in Fig. 4, the front rod 152 also has a male rod 170 that has a large diameter section 172 and a reduced diameter section 174. A top stopper 176 is attached to the section 172 at an end of the rod 170 that is opposite the short end 167 of the female rod 160. The stopper 176 has a diameter that is greater than the diameter of the section 172 and the openings defined in the components of the safety box 10. The section 174 has a length that may be about the same as the length of the section 164 of the female rod 160. The section 174 has a flat bottom surface 178. A pair of pins 180 are attached to the surface 178 at an outer end 182 of the rod 170. It should be understood that the number of pins may be greater or fewer than two pins. For example, one pin may be used or a plurality of pins may be used. The distance between the pins 180 should be about the same as the distance between the cavities 166 so that the pins 180 may be inserted into the cavities 166. The length of the front rod 152 may be adjusted depending on which of the cavities 166 that the pins 180 are inserted into. This is an important feature because the width of the box 10 may be adjusted, as described above . To further improve the integrity and strength of the front rod 152, the assembled female rod 160 and the male rod 170 may be inserted into a sleeve 184, as best shown in Fig. 5, so that an opening 186 defined in the sleeve 184 is aligned with the opening 164 of the female rod 160. This means, that the male rod 170 may protrude outwardly from the sleeve 184. As best shown in Figs. 6-7, a sleeve 188, that has an inner diameter 189 that is greater than an outer diameter 190 of the sleeve 184, may be pulled over the sleeve 184. The sleeve 188 has a large diameter collar 192 at an outer end 194 of the sleeve 188 that is distal from the opening 186 of the sleeve 184. The collar 192 is intended to bear against the stopper 176 of the rod 170 and is sized not to undesirably penetrate the openings of the components of the safety box. The effective length of the sleeves 184, 188 may be adjusted by sliding the sleeve 184 relative to the sleeve 188 to make sure the sleeves cover the rods 160, 170 even though the rods 160, 170 are shifted to a maximum length. In other words, when the pins 180 are inserted into the cavities 166 that are adjacent to an outer end 196 of the rod 160. The lengths of the sleeves 184, 188 are such that the rods 160, 170 will never be exposed even though the rods are fully extended relative to one another. Fig. 7 shows the front rod 152 in almost a fully extended position. The back rod 158 is virtually identical to the front rod 152 and is not described in detail . Fig. 8 shows a rectangular or U-shaped side bar 198. It should be understood that the bar 198 may have any suitable shape including, but not limited to, round and oval shapes. The bar 198 has a front wall 200 and a back wall 202 and a U-shaped side wall 204 disposed therebetween so that an open side 206 is defined therein. The back wall 202 has an inwardly protruding locking pin 208 and the front wall 200 has an outwardly protruding locking pin 210 so that the pins 208, 210 extend in the same direction and the pin 208 extends into the chamber 212 that is defined in the bar 198. The pin 210 has a groove 214 extending across the pin 210. The bar 198 may be mounted to the front bar 152 and the rear bar 158. For simplicity, the safety box 10 is not shown in Fig. 8. The assembly of the locking mechanism is described in more detail below. Fig. 9 shows an alternative embodiment of a locking rod 234 that has a square or rectangular shaped sleeve 258 with an internally threaded inner wall 238. An outer end 240 of the sleeve 258 has an opening 242 extending therethrough for engaging a lock. A threaded male rod 244 may be screwed into the sleeve 258. An opposite end of the rod 244 has a square seat 256 and a square stopper 248. Because the sleeve 258 and the seat 256 are square or rectangular, they cannot be turned inside the square openings that may be defined in the box. Referring back to Fig. 8, the pin 210 is inserted through the opening 164 of the rod 160 and the opening 186 of the sleeve 184 when the opening 186 is aligned with the opening 164 when the side bar 198 is moved in the direction of the arrow 199. The pin 210 is then inserted into the opening 270 of the lock 154. A plate inside the lock 154 may engage the groove 214 by turning a key 272 inserted into the lock 154. Simultaneously, the pin 208 engages and extends through an opening 201 of the locking rod 158. The lock 154 has a groove 274 extending from a bottom side 276 to a top side 278 of the lock 154 so that the lock 154 may be attached to the safety box 10 and is very difficult to break away or remove from the safety box 10. As best shown in Fig. 1, a folded break protector 280 may engage the front end of the box 10. The protector 280 has at least two openings 282 defined therein. The size of the openings 282 are designed to receive the front lock rod 152. One function of the protector 280 is to further improve the strength of the box 10. Preferably, box 10 is equipped with similar protectors wherever the locking mechanism is engaging the box 10, as clearly shown in Fig. 1. With reference to Fig. 10, the box 10 may be attached to a furniture such as to an underside 284 of a table 286. The rear fastening mechanism 16 may be fastened to a metal frame 288 of the table 286 with one way screws. The box 10 may also be fastened to the underside 284 itself with a plurality of screws or other fasteners. The length of the mechanism 16 is adjustable. The front fastening mechanism 14 may, in a similar manner, be fastened to a metal frame 290 of the table 286. When the safety box is adjusted to the correct size, it may be attached to the underside of the table with the fastening mechanisms. The length of the fastening mechanism is adjusted to the size of the metal frame of the table. The computer to be protected is then inserted into the safety box 10 and the locking mechanism 12 is attached and locked to the safety box 10 as described above. If it is necessary to remove the computer from the safety box 10, the reverse procedure is used. The locking mechanism is unlocked with the lock 154 and the locking bars are removed so that the computer may slide out of the safety box. While the present invention has been described in accordance with preferred compositions and embodiments, it is to be understood that certain substitutions and alterations may be made thereto without departing from the spirit and scope of the following claims .
