[0002]The present invention relates to a strap mechanism, and more particularly, to a strap mechanism for drawing an electronic device from a cage conveniently.
[0004]A computer capable of being disassembled easily preferably corresponds to a user's demand in order to disassemble broken components from a computer for detecting and fixing or to disassemble old-type components for updating. A storage device, such a hard disk, is a necessary apparatus of the computer. Therefore, design of assembling and disassembling the storage device conveniently is an important issue.
[0005]Please refer to FIG. 1. FIG. 1 is a schematic diagram of a removable storage device 10 in the prior art. The removable storage device 10 includes at least one electronic device 12. The electronic device 12 can be a storage device, such as a hard disk, an optical disk drive, and so on. The removable storage device 10 shown in FIG. 1 includes two electronic devices 12 disposed as a stack. The removable storage device 10 further includes a cage 14 for holding the electronic devices 12. At least one hole 141 is formed on the cage 14. The removable storage device 10 further includes at least one handle 16 connected to the electronic device 12 so as to pull the electronic device 12 out of the cage 14. A hook 18 is disposed on the handle 16 for engaging inside the opening 141 on the cage 14. When a user presses two ends of the handle 16 inward, the hook 18 can separate from the opening 141 of the cage 14 so as to pull the electronic device 12 out of the cage 14. Due to spatial limitation of the removable storage device 10, dimensions of the handle 16 is small so that the handle 16 is operated constrainedly and uncomfortably, for example, the handle 16 can not be operated by one hand easily and pains the user when the user presses the handle 16 excessively.
[0006]Please refer to FIG. 2. FIG. 2 is a schematic diagram of another removable storage device 30 in the prior art. The removable storage device 30 includes at least one electronic device 32. The electronic device 32 can be a storage device, such as a hard disk, an optical disk drive, and so on. The removable storage device 30 shown in FIG. 2 includes two electronic devices 32 disposed as a stack. The removable storage device 30 further includes a cage 34 for holding the electronic devices 32. At least one hole 341 is formed on the cage 34. The removable storage device 30 further includes at least one handle 36 connected to the electronic device 32 so as to pull the electronic device 32 out of the cage 34. A hook 38 is disposed on the handle 36 for engaging inside the opening 341 on the cage 34. Difference between the removable storage device 30 and the removable storage device 10 is that the user directly draws the handle 36 outward for pulling the electronic device 34 out of the cage 34. The removable storage device 30 has a drawback that it is difficult to disengage the hook 38 from the opening 341 on the cage 34 and the handle 36 is broken easily at a point of force application.
[0007]As mentioned above, the conventional handle of the storage device is operated uncomfortably and constrainedly, unable to be operated by one hand, and broken easily at the point of the force application. Thus, design of a removable mechanism of a removable storage device having preferred structural strength and capable of operating easily is an important issue in the computer industry.
[0008]The present invention provides a strap mechanism for drawing an electronic device from a cage conveniently for solving above drawbacks.
[0009]According to the claimed invention, a strap mechanism includes a first rail including a first locking part for connecting with a lateral surface of an electronic device and disposed inside a cage in a slidable manner, and a first handle part connected to an end of the first locking part, a first slot being formed on the first handle part.

[0023]Please refer to FIG. 3, FIG. 4, and FIG. 5. FIG. 4 is a diagram of combination of the first rail 58 and the other components according to the preferred embodiment of the present invention. FIG. 5 is an exploded diagram of the first rail 58 and the other components according to the preferred embodiment of the present invention. A first slot 621 is formed on the first handle part 62 of the first rail 58. The first slot 621 can be an arc slot. A width in the middle of the first slot 621 is larger than a width of two ends of the first slot 621. A plurality of restraining components 622 is formed on the first handle part 62 and respectively disposed on two sides of the first slot 621 for restraining movement of an end of the strap 64. The strap mechanism 56 further includes at least one positioning component 72 for positioning the first locking part 60 on the lateral surface of the electronic device 52. The positioning component 72 can be a pin. An end of the positioning component 72 is fixed on the first locking part 60.

Due to an elastic force provided by the elastic component 74, the electronic device 52 can be disposed inside the cage 54 tightly. In addition, the elastic component 74 can be made of metal material so as to protect the electronic device 52 from electromagnetic interference. Combination of the second rail 66 and the other components can be the same as the above-mentioned embodiment, and detailed description is omitted herein for simplicity.
[0024]Please refer to FIG. 6 and FIG. 7. FIG. 6 is a diagram of combination of the electronic device 52, the first rail 58, and the second rail 66 according to the preferred embodiment of the present invention. FIG. 7 is an exploded diagram of the electronic device 52, the first rail 58, and the second rail 66 according to the preferred embodiment of the present invention. At least one hole 521 is formed on two lateral surfaces of the electronic device 52. Ends of the positioning components 72 are fixed on the first locking part 60 and the second locking part 68, respectively, and the other ends of the positioning components 72 are for inserting into the holes 521 on the electronic device 52 so as to combine the first locking part 60, the second locking part 68, and the electronic device 52. A second slot 701 is formed on the second handle 70 of the second rail 66. The second slot 701 can be an arc slot. A width in the middle of the second slot 701 is larger than a width of two ends of the second slot 701.

The positioning component 72 is for positioning the second locking part 68 on the other lateral surface of the electronic device 52. The positioning component 72 can be a pin. An end of the positioning component 72 is fixed on the second locking part 68. For example, a rack can be disposed on the end of the positioning component 72 so that the positioning component 72 can be fixed on the second locking part 68 firmly. The other end of the positioning component 72 is for inserting into the hole 521 of the electronic device 52 so as to combine the second locking part 68 and the electronic device 52. The elastic component 74 is connected to the second locking part 68 and disposed between the second locking part 68 and the cage 54. The elastic component 74 can be an elastic slice. When the electronic device 52 is disposed inside the cage 54, the elastic component 74 connected to the first locking part 60 and the second locking part 68 can be elastically deformed. Due to the elastic force provided by the elastic component 74, the electronic device 52 can be disposed inside the cage 54 tightly. In addition, a hook 63 is formed on the first rail 58, and a hook 71 is formed on the second rail 66. When the electronic device 52 is disposed inside the cage 54, the hook 63 of the first rail 58 and the hook 71 of the second rail 66 bounce outward and insert into the openings 541 on the cage 54 due to the first rail 58 and the second rail 66 made of elastic material, so that electronic device 52 can be fixed inside the cage 54 tightly.
[0025]Furthermore, the strap 64 includes a strap body 641, and a width of the strap body 641 is larger than each width of the first slot 621 and the second slot 701. The strap 64 further includes two passing parts 642 connected to two ends of the strap body 641 and for passing through the first slot 621 and the second slot 701 respectively, and a width of the passing part 642 is smaller than each width of the first slot 621 and the second slot 701. The strap 64 further includes two wedging parts 643 respectively connected to the passing parts 642, and a width of the wedging part 643 is larger than each width of the first slot 621 and the second slot 701 so that the strap body 641 and the wedging parts 643 are respectively installed on two sides of the first handle part 62 and the second handle part 70 when the passing parts 642 pass through the first slot 621 and the second slot 701. The strap body 641, the passing parts 642, and the wedging parts 643 can be integrated monolithically. The strap body 641, the passing parts 642, and the wedging parts 643 further can be separated components. Assembly of the strap 64, the first handle part 62, and the second handle part 70 is introduced as follows. First the strap 64 is disposed between the first handle part 62 and the second handle part 70 transversely so that two ends of the wedging parts 643 can pass through the first slot 621 and the second slot 701. Next, the strap 64 is turned from transverse placement to vertical placement. The widths in the middle of the first slot 621 and the second slot 701 are larger than the widths of the two ends of the first slot 621 and the second slot 701 so as to provide a space to rotate the passing parts 642 of the strap 64. Please refer to FIG. 8. FIG. 8 is a top view of the removable storage device 50 according to the preferred embodiment of the present invention. The wedging parts 643 are restrained between the restraining components 622 of the first handle part 62 and the restraining components 702 of the second handle part 70. That is to say, the restraining components 622 of the first handle part 62 and the restraining components 702 of the second handle part 70 restrain the two ends of the strap 64 from moving in the Y direction, respectively. Because the widths of the strap body 641 and the wedging parts 643 are larger than the widths of the first slot 621 and the second slot 701 and the widths of the passing parts 642 are smaller than the widths of the first slot 621 and the second slot 701, the strap 64 can be fixed between the first handle part 62 and the second handle part 70.
[0026]Please refer to FIG. 9 and FIG. 10. FIG. 9 is a diagram of the strap 64 being drawn in the Y direction according to the preferred embodiment of the present invention. FIG. 10 is a force diagram of the strap 64 being drawn in the Y direction according to the preferred embodiment of the present invention. Because the strap 64 is made of elastic material, the strap 64 is deformed as a curve when the middle of the strap 64 is forced toward the Y direction. The strap 64 is drawn in a direction by a force F, and the force F can be decomposed into a component force Fx in a X direction and a component force Fy in a Y direction. The X direction is perpendicular to the Y direction. The component force Fx can draw the first rail 58 and the second rail 66 close toward each other, so that the hook 63 of the first rail 58 and the hook 71 of the second rail 66 are moved inward and disengaged from the opening 541 on the cage 54. The component force Fy can pull the electronic device 52 connected to the first rail 58 and the second rail 66 out of the cage 54. Therefore, the electronic device 52 can be taken away conveniently. In addition, the restraining components 622 of the first handle part 62 and the restraining components 702 of the second handle part 70 can be designed as arc structures so as to guide the wedging parts 643 of the strap 64 to move along a track of the arc structure when being forced by the force F. It means the strap 64 is forced by the component force Fx first so as to disengage the hook 63 and the hook 71 from the opening 541 on the cage 54, and then the strap 64 is forced by the component force Fy so as to pull the electronic device 52 out of the cage 54.
[0027]Comparing to the prior art, the strap mechanism of the present invention can be assembled conveniently and the removable storage module can be removed easily. Because the strap is made of plastic material having stronger strength, a drawback of the conventional storage device that the handle is broken easily when being pressed excessively can be overcome, so as to increase the structural stability of the strap mechanism and to improve reliability of the removable storage module. Therefore, the present invention provides a strap mechanism capable of operating easily and having preferred structural strength.
