According to an embodiment of the present invention, the extracting module 25 comprises a handle 250, two springs 251, and an extracting piece 254, wherein the extracting piece 254 comprises one or more joining portion(s) 253 and a first contact portion 255. According to an embodiment of the present invention, the first contact portion 255 can be a cam member or an element that has an inclining plane. When user pulls the handle 250 out, the extracting module 25 is capable of allowing the first contact portion 255 to move toward right-hand side in response to the movement of the bracket 200, so as to apply force onto the driven module 24 and thus change the condition of the driven module 24. According to an embodiment of the present invention, the driven module 24 is disposed on the bracket 200 and comprises a driven piece 242. According to the embodiment of the present invention, the driven piece 242 further comprises one or more retaining portion(s) 244, a second contact portion 241, and one or more locking portion(s) 240. The driven module 24 is utilized for making the first contact portion 255 of the extracting module 25 apply a force onto the second contact portion 241 of the driven module 24, so as to change the condition of the driven module 24, so that the locking portion 240 moves from a locked position to an unlocked position, when the user pulls the handle 250 out.
According to an embodiment of the present invention, the release mechanism comprises the extracting module 25 and the driven module 24. According to an embodiment of the present invention, when the apparatus 120 is inserted into the enclosure 110, the connectors (not shown) on the apparatus 120 can be electrically connected to the connectors on the backplane (not shown).
According to an embodiment of the present invention, in the bracket 200, the side walls 210, the bottom plate 220, the front top plate 230, the rear top plate 235, and the front panel 260 are jointed one another, wherein there are a plurality of screw holes in the side walls 210, thus the screws 216 can be used to conjoin the front top plate 230 and the rear top plate 235 and the side walls 210 together through the screw holes.
According to an embodiment of the present invention, the side walls 210 have one or more passage hole(s) 215 therein. Please refer to FIG. 6 and FIG. 7. When the apparatus 120 is inserted into the enclosure 110 to be under a locked position (i.e., the first condition shown in FIG. 7), because there is no force that is applied onto the driven module 24, the locking portions 240 of the driven piece 242 stretches out of the passage hole 215 to get stuck in the corresponding locking holes 117 (as shown in FIG. 6) in the enclosure 110, and thus the apparatus 120 is fixed within the enclosure 110.
According to an embodiment of the present invention, there are a plurality of heat-dissipating holes 265 in the front panel 260. When the heat-dissipating fans 290 works, the heat generated from the system 100 can be dissipated to the air through the plurality of heat-dissipating holes 265. According to an embodiment of the present invention, the front panel 260 has one or more handle hole(s) 266, through which the handle 250 passes, so as to conjoin with the extracting piece 254.
According to an embodiment of the present invention, the majority of the elongated portion 250b of the handle 250 is located within the front panel 260 when there is no force that is applied onto the handle 250.
When drawing the apparatus 120 out from the enclosure 110, the elongated portion 250b of the handle 250 passes through the handle hole 266 to stretch out of the front panel 260 due to the pulling force.
Please refer to FIG. 5 again, according to an embodiment of the present invention, the handle 250 comprises a holding portion 250a and at least one elongated portion 250b. When assembling the extracting module 25, the two ends of the elongated portion 250b pass through the two handle holes 266 of the front panel 260 respectively, which allows the holding portion 250a to be positioned on an outer side of the front panel 260, and allows the elongated portion 250b to be positioned on an inner side of the front panel 260. Inside the apparatus 120 (i.e., the inner side of the front panel 260), the two joining pieces 252 sequentially and respectively pass through the joining portions 253 of the extracting piece 254 and the springs 251 so as to conjoin with the two ends of the elongated portion 250b. According to an embodiment of the present invention, the joining piece 252 can be a screw, the joining portion 253 can be a screw hole, and the ends of the elongated portion 250b can have screw threads corresponding to the screws; however, it is not limited to this embodiment of the present of invention, the joining piece 252 can be other coupling devices capable of conjoining the joining portion 253 and the elongated portion 250b together. Moreover, the spring 251 is placed between the front panel 260 and the extracting piece 254. When there is no force that is applied onto the handle, majority of the elongated portion 250b of the handle 250 is located within the apparatus 120 due to the elastic force of the spring 251, and only the holding portion 250a is exposed on the outer side of the front panel 260. According to an embodiment of the present invention, the extracting piece 254 is an L-shaped sheet member having two surfaces, wherein there is a hole 256 at the intermediate connecting portion of the L-shaped sheet member, that is to say, the hole 256 is located in the two surfaces of the extracting piece 254; however, it is not limited to this embodiment of the present invention, the extracting piece 254 can be other shapes, and the hole can be omitted.
Please refer to FIG. 5 again, when assembling the driven module 24, the driven piece 242 is placed into the apparatus 120 (i.e., the inner side of the side wall 210), so that the locking portion 240 of the driven piece 242 penetrates through the passage hole 215 of the side wall 210 and protrudes out of the side wall 210, and then a retainer 243 is used to secure driven piece 242 onto the side wall 210 by penetrating through the hole 212 of the side wall 210 and the retaining portion 244 of the driven piece 242 sequentially. According to an embodiment of the present invention, the retainer 243 can be a rivet, and the retaining portion 244 can be a rivet hole. However, if the bracket 200 of the embodiment of the present invention does not have to have the side wall 210, then the locking portion 240 does not need to pass through the passage hole 215. According to an embodiment of the present invention, the driven piece 242 is a long sheet member with elasticity, and the retaining portion 244 of the driven piece 242 is flatted on the inner side of the side wall 210 and is fixed by the retainer 243. Furthermore, according to an embodiment of the present invention, the second contact portion 241 is a sheet-like elastic member, is conjoined to a plane of the driven piece 242 at an angle, and obliquely extends toward the inside of the apparatus 120. According to an embodiment of the present invention, the locking portion 240 of the driven piece 242 is a triangular-like sheet member, protrudes from the outer side of the driven piece 242 (the opposite side of the location of the second contact potion 241) and has a leading edge and a trailing edge. According to an embodiment of the present invention, the locking portion 240 is perpendicular to the side wall 210, and the retainer 243 can be a screw.
Please refer to FIG. 6 which shows that the apparatus is secured into the enclosure, When the apparatus 120 is under a locked position due to securing the apparatus 120 into the enclosure 110, the locking portion 240 of the driven piece 242 protrudes out of the locking hole 117 of the partition plate 115 of enclosure 110, and meanwhile, because the leading edge of the locking portion 240 abuts against the leading edge of the locking holes 117, the apparatus 120 cannot move forward in response to the enclosure 110 (toward the right hand side in the FIG. 6), so that the apparatus 120 can be secured within the enclosure 110, wherein the majority of the elongated portion 250b is located within the apparatus 120, and only the holding portion 250a is shown on the outer side of the front panel 260.
Please refer to FIG. 7 to FIG. 10, FIG. 7 to FIG. 10 are the top views illustrating the apparatus 120 of the present invention under the first, second, third, and fourth conditions respectively.
FIG. 7 shows the top view illustration that the apparatus 120 is secured into the enclosure 110 (top of enclosure 110, front top plate 230 and rear top plate 235 are omitted) and is under the first condition. When the apparatus 120 is under the first condition, the locking portion 240 of the driven piece 242 may stretch out of the passage hole 215 to get stuck in the corresponding locking holes 117 of the partition plate 115, and further the locking portion 240 and the locking holes 117 abut against each other. And meanwhile, the end of the second contact portion 241 of the driven piece 242 protrudes into the hole 256 of the extracting piece 254, and the displacement stroke from the first contact portion 255 of the extracting piece 254 to the second contact portion 241 of the driven piece 242 is set to d.
Please refer to FIG. 8 which shows the top view illustration that the handle 250 of apparatus 120 is applied with a pulling force F1 thereon (top of enclosure 110, front top plate 230 and rear top plate 235 are omitted), and it is under the second condition. As shown in FIG. 8, when the handle 250 is applied with a pulling force F1 thereon, and the handle 250 moves forward in response to the front panel 260, the extracting piece 254 and the hole 256 of the extracting piece 254 move forward, too, so that the end of the second contact portion 241 further protrudes into the hole 256 of the extracting piece 254; meanwhile, the first contact portion 255 of the extracting piece 254 moves forward in response to the driven piece 242 according to the displacement stroke d, which makes a distance between the second contact portion 241 of the driven piece 242 and the first contact portion 255 of the extracting piece 254, gradually decreased from d to zero (the distance equal to zero means that the first contact portion 255 gets contact with the second contact portion 241); moreover, the elongated portion 250b of the handle 250 gradually stretches out of the front panel 260. During the process that the distance between the first contact portion 255 and the second contact portion 241 is gradually decreased from d to zero, the length which the elongated portion 250b of the handle 250 stretch out of the front panel 260 is further increased by d, and the length of the spring 251 is also gradually decreased by d due to the pulling force. However, the corresponding position between the locking portion 240 and the locking holes 117 remains unchanged, and the locking portion 240 and the locking holes 117 remain to abut against each other, so that the apparatus 120 cannot move forward in response to the enclosure 110; therefore, the apparatus 120 is still locked within the enclosure 110. Accordingly, under the first condition, the design of the present invention can prevent the apparatus 120 from being turned into the unlocked position due to an unexpected force or due to a force applied by user's carelessness, even though there is a force that changes the apparatus 120 from the first condition into the second condition. It should be noted that the pulling force F1 is not a constant and may increase gradually as the handle 250 moves forward.
Please refer to FIG. 9. FIG. 9 shows the top view illustration that the handle 250 of apparatus 120 is applied with a pulling force F2 thereon (top of enclosure 110, front top plate 230 and rear top plate 235 are omitted), and it is under the third condition After the second condition, when the handle 250 is applied with another pulling force F2 which is larger than the pulling force F1, so as to render the handle 250 and the extracting piece 254 move forward in response to the front panel 260, the first contact portion 255 of the extracting piece 254 moves toward the front panel 260, abuts against an inclined plane of the second contact portion 241 of the driven piece 242, and pushes the second contact portion 241 forward. According to an embodiment of the present invention, the first contact portion and the second contact portion have at least one inclined plane, and the orientation of the inclined plane is not perpendicular to the moving direction of the handle. Because the retaining portion 244 of the driven piece 242 is fixed on the side wall 210 by the retainer 243 to form a fulcrum, and the driven piece 242 is an elastic member, the driven piece 242 gradually deforms inward due to the fulcrum achieved by the retaining portion 244. At this moment, the locking portion 240 of the driven piece 242 gradually makes a displacement, because the driven piece 242 gradually deforms inward, and then the locking portion 240 that originally protruded into the passage hole 215 of the side wall 210 may return back into the passage hole 215 gradually. At this moment, the corresponding position between the locking portion 240 and the locking hole 117 will be changed, and further the locking portion 240 and the locking hole 117 do not abut against each other any more, the apparatus 120 can be drawn out of the enclosure 110 due to an external force, which is the third condition at this moment. Under the third condition, the first contact portion 255 of the extracting piece 254 further moves by a distance dt, and the first contact portion 255 has a total displacement of d+dt including addition of the displacement d under the second condition, and the spring 251 is also compressed by length of d+dt. Before completing the third condition, the force F2 applied onto the handle 250 is larger than F1, because the spring 251 needs larger force to be compressed from the second condition where the spring 251 is compressed by d, to the third condition where the spring 251 is compressed by d+dt, and it also needs to supply an additional force to bend the driven piece 242 to overcome a friction that is generated between the first contact portion 255 and the second contact portion 241, and to overcome another friction generated between the locking portion 240 and the locking hole 117. Upon reaching the third condition, because the strength of F2 will be changed again due to disappearance of force which is caused by losing the contact between the locking portion 240 and the locking holes 117, and due to the change of the corresponding forces applied onto each of elements, F2 is also not a constant, and will be changed again. The F2 will be increased and is finally larger than F1 as the handle 250 moves forward from the second condition, and F2 is also changed according to the corresponding position among each of elements, and is changed again upon reaching the third condition.
Please refer to FIG. 10. FIG. 10 shows the top view illustration that the handle 250 of apparatus 120 is applied with the pulling force F2 thereon (top of enclosure 110, front top plate 230 and rear top plate 235 are omitted), and then the fourth condition is reached. After reaching the third condition, because the locking portion 240 of the driven piece 242 and the locking hole 117 are separated and do not abut against each other any more, the apparatus 120 can be drawn from the enclosure 110. As shown in FIG. 10, the apparatus 120 is drawn from the enclosure 110 by a distance D.
In addition, while the apparatus 120 is drawn from the enclosure 110, and the force applied onto the handle 250 is disappeared, the elastic force generated by the spring 251 causes the extracting piece 254 to go back to its original position in a reverse direction, and the first contact portion 255 of the extracting piece 254 returns to its original position; furthermore, the driven piece 242 is also recovered to original condition, and the locking portion 240 of the driven piece 242 can stretch and protrude out of the passage hole 215 of the side wall 210 again at the same time, as shown in FIG. 4.
Please refer to FIG. 11. FIG. 11 shows a schematic diagram illustrating that the apparatus 120 applied by an external force thereon is being inserted back into the enclosure 110. As shown in FIG. 11, when the triangular-like locking portion 240 abuts against the partition plate 115 of enclosure 110, the oblique plane of the trailing edge of the locking portion 240 is pushed and temporarily returned back into the passage hole 215, and the driven piece 242 generates bending deformation due to the retraction of the locking portion 240. After completion of inserting the apparatus 120 into the enclosure 110, the locking portion 240 stretches out of the passage hole 215 and protrudes into the locking hole 117 of the partition plate 115 again, so that the locking portion 240 and the locking holes 117 abut against each other, and the apparatus 120 is secured within the enclosure 110.
With the example and explanations above, the features and spirits of the invention will be hopefully well described. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teaching of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
