Description
- This application claims priority to Taiwan Application Serial Number 97121582, filed Jun. 10, 2008, which is herein incorporated by reference.
- 1. Field of the Invention
- The invention relates to a mobile rack and, more particularly, to a mobile rack facilitating extracting or inserting thereof.
- 2. Description of the Related Art
- With the development of portable disk drives, to exchange the needed data quickly, many users only need take an extractable disk drive and install the extractable disk drive on a machine.
- Conventionally, machines mostly adopt locking devices in cooperation with extractable disk drives. To extract an extractable disk drive from the machine, one hand of a user presses a releasing button of the locking device to release the extractable disk drive, and the other hand extracts the extractable disk drive. However, according to the above design, a certain space on the machine has to be occupied, and two hands of the user are needed to extract the extractable disk drive. Similarly, the outer surface of the extractable disk drive has a dragging element. When the user is to extract the extractable disk drive from the machine, he or she uses the dragging element of the extractable disk drive to extract the extractable disk drive from the machine.
- However, considering the convenience of detaching and assembling the extractable disk drive, flatness and smoothness of the surface of the machine or the disk drive, or the material cost of the accessory (the button or the dragging element), the mechanism of detaching and assembling the extractable disk drive in the conventional machine still can be improved.
- This invention provides a mobile rack including a fixed bracket, a tray, a movable element, and a guiding groove. The fixed bracket has a containing part. The tray is disposed in the containing part for carrying an object, and it is capable of being slidingly extracted from or inserted into the containing part. At least one elastic element is connected between the fixed bracket and the tray. The movable element and the guiding groove correspond to each other and can be exchangeably disposed at the fixed bracket or the tray. The movable element is disposed at one surface of the fixed bracket and the tray and has a protrusion. The guiding groove is disposed at the other surface of the fixed bracket and the tray and opposite the movable element. The guiding groove includes a protrudent unit and a track. The protrusion is inserted into the track and slides along the protrudent unit. The protrudent unit has a first guiding portion and a stopping portion.
- When the tray is pushed to be inserted into the containing part, the elastic element is compressed and deformed to store a restoring force, and the protrusion driven by the movable element slides along the first guiding portion and the inner wall of the guiding groove and be against the stopping portion to stop the elastic element releasing the restoring force.
- When the tray is pulled to be extracted from the containing part, the protrusion driven by the movable element leaves away from the stopping portion to make the elastic element release the restoring force. Thus, the tray is extracted from the containing part.
- In one preferred embodiment of the invention, one end of the movable element may be pivotally connected to an inner side of the fixed bracket, and the guiding groove may be disposed at an outer side of the tray. At that moment, the first guiding portion may be at one end of the protrudent unit away from an opening of the containing part. When the tray is inserted into the containing part, the first guiding portion may drive one end of the movable element having the protrusion to rotate toward a first direction. The first guiding portion may be a convex corner of the protrudent unit protruding toward the direction away from the opening of the containing part. The stopping portion may be at one end of the protrudent unit adjacent to the opening of the containing part. The stopping portion may be a concave corner of the protrudent unit recessed toward the direction away from the opening of the containing part.
- In another embodiment of the invention, when the movable element may be pivotally connected to an outer side of the tray, and the guiding groove may be disposed at an inner side of the fixed bracket, the stopping portion may be at one end of the protrudent unit away from the opening of the containing part, and the first guiding portion may be at one end of the protrudent unit adjacent to the opening of the containing part.
- In addition, to make the tray slide smoothly, one surface of the fixed bracket parallel to the sliding direction of the tray has at least one long opening. The tray has a protrudent pole corresponding to the long opening. Thus, when the tray slides in the containing part, each protrudent pole passes through the corresponding long opening and slides along the long opening to successfully guide the tray in sliding.
- To sum up, the mobile rack of the invention can facilitate extracting or inserting the object on the tray without the dragging element or the locking device. The structure is simply, and it is convenient for users to operate the mobile rack.
- These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings.

FIG. 1 is an exploded diagram of a mobile rack according to a preferred embodiment of the invention.FIG. 2 is a reference diagram showing the operation of extracting atray 20 from afixed bracket 10 according to a preferred embodiment of the invention. Amobile rack 1 applied to a machine (such as a desktop computer, a notebook computer, or a server and so on) includes afixed bracket 10, atray 20, amovable element 30, and a guidinggroove 40. Thefixed bracket 10 is fixed to the machine and has a containingpart 11 for containing thetray 20. Thetray 20 is used for carrying anobject 21 and, more particularly, for carrying a disk unit (such as an optical disk drive or a hard disk drive). Thetray 20 can be slidingly extracted from the containingpart 11 to help a user extract the disk unit, or it can be slidingly inserted into the containingpart 11 to help the user insert the disk unit. At least one elastic element 50 (such as a tension spring or a compression spring) is disposed between thefixed bracket 10 and thetray 20. - In addition, the
movable element 30 and the guidinggroove 40 correspond to each other and can be exchangeably disposed at thefixed bracket 10 or thetray 20, respectively. One end of themovable element 30 is pivotally connected to one of thefixed bracket 10 and thetray 20, and the other end is a free end. Themovable element 30 has aprotrusion 31 at a place facing to the guidinggroove 40, and it can sway to and fro. The guidinggroove 40 is a recessed region and has anindependent protrudent unit 41. Atrack 42 is formed between aninner wall 400 of the guiding groove and theprotrudent unit 41. Theprotrusion 31 of themovable element 30 can be inserted into thetrack 42 and slide along thetrack 42. Two opposite ends of theprotrudent unit 41 have at least a first guidingportion 410 and astopping portion 414, respectively. In addition, theinner wall 400 of the guiding groove still has a plurality of guiding surfaces to guide theprotrusion 31 in sliding. The guiding surfaces of theinner wall 400 of the guiding groove are described hereinbelow in detail. -
FIG. 3 is a schematic diagram of the guidinggroove 40 of the mobile rack according to a preferred embodiment of the invention. When a user pushes thetray 20 to make thetray 20 and the disk unit inserted into the containingpart 11, theelastic element 50 is compressed and deformed to store a restoring force. At that moment, the end of themovable element 30 having theprotrusion 31 rotates around the end pivotally connected to the fixedbracket 10, to make theprotrusion 31 move along theprotrudent unit 41 in thetrack 42. Further, via thefirst guiding portion 410 and a part of guiding surfaces, theprotrusion 31 slides along thefirst guiding portion 410 until being against the stoppingportion 414 to stop theelastic element 50 restoring deformation further to store the restoring force. - When the user is to extract the disk unit in the containing
part 11, he or she pushes dietray 20 toward the containingpart 11. At that moment, theprotrusion 31 leaves away from the stoppingportion 414 to make theelastic element 50 release the restoring force. Via guiding of the stoppingportion 414 and the other parts of guiding surfaces in the guidinggroove 40, the end of themovable element 30 having theprotrusion 31 rotates around the end pivotally connected to the fixedbracket 10. Thus, theprotrusion 31 moves along thetrack 42 and returns to thefirst guiding portion 410 by the restoring force to make thetray 20 extracted from the containingpart 11. - In a preferred embodiment of the invention, the fixed
bracket 10 may include aU-shaped cover 13 and aplate 15 to form a hollow space as the containingpart 11. One end of themovable element 30 may be pivotally connected to the inner side of theU-shaped cover 13. Thus, the end of themovable element 30 having theprotrusion 31 can rotate around the end pivotally connected to the fixedbracket 10. - When the
movable element 30 is pivotally connected to the inner side of theU-shaped cover 13, the guidinggroove 40 is integrally formed at the outer surface of thetray 20 facing to theprotrusion 31. Thefirst guiding portion 410 is at the end of theprotrudent unit 41 away from the opening of the containingpart 11, and it may be a convex corner of theprotrudent unit 41 protruding toward the direction away from the opening of the containingpart 11. The stoppingportion 414 of theprotrudent unit 41 is at the end of theprotrudent unit 41 adjacent to the opening of the containingpart 11, and it may be a concave corner of theprotrudent unit 41 recessed toward the direction away from the opening of the containingpart 11. - Since the
movable element 30 and the guidinggroove 40 can be exchangeably disposed at the fixedbracket 10 or thetray 20, respectively, in another embodiment of the invention, one end of themovable element 30 can be pivotally connected to the outer side of thetray 20. Thus, the end of themovable element 30 having theprotrusion 31 can rotate around the end pivotally connected to the fixedbracket 10. The guidinggroove 40 is integrally formed at the inner side of the fixedbracket 10. Thefirst guiding portion 410 of theprotrudent unit 41 is at the end of theprotrudent unit 41 adjacent to the opening of the containingpart 11, and it may be a convex corner of theprotrudent unit 41 protruding toward the direction adjacent to the opening of the containingpart 11. The stoppingportion 414 of theprotrudent unit 41 is at the end of theprotrudent unit 41 away from the opening of the containingpart 11, and it may be a concave corner of theprotrudent unit 41 recessed toward the direction adjacent to the opening of the containingpart 11. Therefore, according to the description of the guidinggroove 40 inFIG. 3 , the features in another embodiment can be obtained by conversion from theFIG. 1 . - The convex corner in the above embodiments can be formed by a first
lateral surface 412 and a secondlateral surface 413 of theprotrudent unit 41. The firstlateral surface 412 is oblique, and the sliding length of theprotrusion 31 along the firstlateral surface 412 is greater than that of theprotrusion 31 along the secondlateral surface 413. When thetray 20 is pushed to be inserted into the containingpart 11, the firstlateral surface 412 stops theprotrusion 31 to drive the end of themovable element 30 having theprotrusion 31 to rotate toward a first direction (such as leftward or rightward). Thus, theprotrusion 31 can slide along the firstlateral surface 412 to guide theprotrusion 31 in moving in thetrack 42 relatively, such that theprotrusion 31 can be guided to relatively move to the stoppingportion 414 again. - The concave corner in the embodiments can be formed by a third
lateral surface 416 and a fourthlateral surface 417. The thirdlateral surface 416 is oblique, and the sliding length of theprotrusion 31 along the thirdlateral surface 416 is greater than that of theprotrusion 31 along the fourthlateral surface 417. When thetray 20 is pulled to be extracted from the containingpart 11, theprotrusion 31 contacts the fourthlateral surface 417 and is stopped by the fourthlateral surface 417. Then the end of themovable element 30 having theprotrusion 31 is driven to rotate toward a second direction (such as downward or leftward) and theprotrusion 31 is made to slide along the fourthlateral surface 417 and to relatively move in thetrack 42. Therefore, thetray 20 can be extracted from the containingpart 11 via the restoring force of the elastic element. - The structures of the
first guiding portion 410 and the stoppingportion 414 - The guiding surfaces are used to limit the route of the
protrusion 31, respectively, to drive themovable element 30 to properly rotate toward the first direction or the second direction. Thus, when thetray 20 is pushed to be inserted into the containingpart 11, theprotrusion 31 moves in thetrack 42, sliding from thefirst guiding portion 410 to the stoppingportion 414. When thetray 20 is pulled to be extracted from the containingpart 11, theprotrusion 31 moves in thetrack 42, leaving away from the stoppingportion 414 to make theelastic element 50 release the restoring force. Therefore, thetray 20 is extracted from the containingpart 11. -
FIGS. 4A-4J are exploded diagrams showing positions of theprotrusion 31 moving in thetrack 42 when thetray 20 is slidingly extracted from or inserted into the containingpart 11 according to a preferred embodiment of the invention. InFIG. 1 ,FIG. 3 , andFIGS. 4A-4J , theinner wall 400 of the guidinggroove 40 includes at least two first guiding surfaces 401, 401′ corresponding to each other up and down, two second guiding surfaces 402, 402′ corresponding to each other up and down, and asecond guiding portion 44. - In
FIGS. 4A-4B , the two first guiding surfaces 401, 401′ are oblique and form an angle outwards. The angle may be a positioningportion 43. When thetray 20 is pulled to be extracted from the containingpart 11, the positioningportion 43 can hold theprotrusion 31 before thetray 20 is inserted into the containingpart 11. In addition, according to the sliding direction of thetray 20, the angle of thepositioning portion 43 uprightly faces to the firstlateral surface 412 of the concave corner. Therefore, when thetray 20 is inserted into the containingpart 11, and theprotrusion 31 relatively moves according to the sliding direction of thetray 20, theprotrusion 31 can be prevented from contacting the secondlateral surface 413 and being incorrectly guided by the secondlateral surface 413. - In
FIG. 4C , the two second guiding surfaces 402, 402′ are parallel to each other, and they are disposed at two sides of theprotrudent unit 41, respectively. One end of the second guiding surfaces 402, 402′ is connected to one end of the first guiding surfaces 401 or 401′, and the second guiding surfaces 402, 402′ formparallel sections corresponding protrudent unit 41, respectively. Theparallel sections first guiding portion 410 and the stoppingportion 414. - Therefore, when the
tray 20 is pushed to be inserted into the containingpart 11, theprotrusion 31 is guided by the upper first guidingsurface 401 and relatively moves along the upperparallel section 45. According to the sliding direction of thetray 20, the uppersecond guiding surface 402 guides theprotrusion 31 in relatively moving in thetrack 42 continually to contact the upper portion of athird guiding surface 403. - Similarly, in
FIG. 4J , when thetray 20 is pulled to be extracted from the containingpart 11, theprotrusion 31 relatively moves along the lowerparallel section 45′ according to the sliding direction of thetray 20. The lowerparallel section 45′ can guide theprotrusion 31 in uprightly contacting the lowerfirst guiding surface 401′ to return to thepositioning portion 43. - The
second guiding portion 44 has the upper portion of thethird guiding surface 403, the upper portion of afourth guiding surface 404, and the lower portion of afifth guiding surface 405. InFIGS. 4D-4E , one end of thethird guiding surface 403 is connected to one end of the uppersecond guiding surface 402, and the other end extends toward the lowersecond guiding surface 402′ and away from the stoppingportion 414. Therefore, when thetray 20 is inserted into the containingpart 11, theprotrusion 31 guided by the uppersecond guiding surface 402 relatively moves, and then the thirdlateral surface 416 contacts and presses theprotrusion 31 to drive one end of themovable element 30 having theprotrusion 31 to rotate toward the second direction. Thus, theprotrusion 31 can face to the thirdlateral surface 416 of the stoppingportion 414, and the situation that theprotrusion 31 slides back to thepositioning portion 43 via the upperparallel section 45 since it fails to contact the thirdlateral surface 416 after the force of pushing thetray 20 disappears can be prevented. - In
FIGS. 4E-4F , thefourth guiding surface 404 is adjacent to thethird guiding surface 403 and the thirdlateral surface 416, and it is parallel to the sliding direction of thetray 20. Thefourth guiding surface 404 and thefifth guiding surface 405 form aprotrudent block 441 which faces to the stoppingportion 414. Thus, when theprotrusion 31 passes theparallel section 45 and thethird guiding surface 403 along thefirst guiding portion 410 to contact thefourth guiding surface 404, and after the force of pushing thetray 20 disappears, theprotrusion 31 is between the thirdlateral surface 416 and the fourthlateral surface 417 of the stopping portion 414 (as shown inFIGS. 4F-4G ) via the restoring force of theelastic element 50 and the limitation of theprotrudent block 441. - In
FIGS. 4H-4I , one end of thefifth guiding surface 405 is connected to one end of thefourth guiding surface 404 adjacent to the thirdlateral surface 416, and the other end extends toward the oblique direction of thefourth guiding surface 404. - Therefore, when the
tray 20 is pulled to make theprotrusion 31 leave away from the stoppingportion 414, thefifth guiding surface 405 contacts and presses theprotrusion 31 to drive one end of themovable element 30 having theprotrusion 31 to rotate toward the second direction until theprotrusion 31 can face to the lowerfirst guiding surface 401′. Theprotrusion 31 uprightly contacts the lowerfirst guiding surface 401′ and returns to thepositioning portion 43 via the restoring force of theelastic element 50 and the guiding of the lowerparallel section 45′. - In addition, the second guiding
portion 44 has asixth guiding surface 406 between thethird guiding surface 403 and thefourth guiding surface 404 and aseventh guiding surface 407 between thefifth guiding surface 405 and the lowersecond guiding surface 402′. Thus, theprotrusion 31 can smoothly cooperate with thethird guiding surface 403 or thefourth guiding surface 404 to relatively move. - In addition, according to the above, the fixed
bracket 10 has at least onelong opening 131 in one surface thereof parallel to the sliding direction of thetray 20. Thetray 20 has aprotrudent pole 201 corresponding to thelong opening 131. Thus, when thetray 20 slides in the containingpart 11, theprotrudent pole 201 passes through the correspondinglong opening 131 and slides along thelong opening 131 to successfully guide thetray 20 in sliding. - The connection between the
movable element 30 and the fixedbracket 10 or thetray 20 in the invention is not limited to the pivotal connection. Themovable element 30 may also be a metal sheet, and theprotrusion 31 is disposed at one edge of themovable element 30. Theprotrusion 31 can slide along thetrack 42 circularly via the restoring characteristic of the metal sheet. - Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
