Abstract

A strap mechanism for drawing an electronic device from a cage in a first direction is disclosed. The strap mechanism includes a first rail. The first rail includes a first locking part for connecting with a lateral surface of the electronic device and disposed inside the cage in a slidable manner, and a first handle part connected to an end of the first locking part. A first slot is formed on the first handle part. The strap mechanism further includes a strap. A first end of the elastic strap is inserted inside the first slot. The strap is for contacting against the first handle part so as to provide a component force in the first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the elastic strap is generated by being pulled in the first direction.

Claims

1. A strap mechanism comprising:

a first rail comprising;

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; and

a strap, a first end of the strap being inserted inside the first slot, the strap being for contacting against the first handle part so as to provide a component force in a first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the strap is generated by being pulled in the first direction, the strap comprising;

a strap body, a width of the strap body being larger than a width of the first slot;

a passing part connected to the strap body and for passing through the first slot, a width of the passing part being smaller than the width of the first slot, and a width in a middle of the first slot being larger than a width of two ends of the first slot so as to provide a space to rotate the passing part; and

a wedging part connected to the passing part, a width of the wedging part being larger than the width of the first slot so that the passing part passes through the first slot and the strap body and the wedging part are respectively installed on two sides of the first handle part.

2. The strap mechanism of claim 1 further comprising:

at least one positioning component for positioning the first locking part on the lateral surface of the electronic device.

3. The strap mechanism of claim 2, wherein the positioning component is a pin, an end of the pin is fixed on the first locking part, and another end of the pin is for inserting into a hole on the lateral surface of the electronic device.

4. The strap mechanism of claim 1 further comprising:

an elastic component connected to the first locking part and disposed between the first locking part and the cage.

5. The strap mechanism of claim 4, wherein the elastic component is an elastic slice.

6. The strap mechanism of claim 1, wherein a plurality of restraining components is formed on the first handle part and respectively disposed on two sides of the first slot for restraining a movement of the first end of the strap.

7. The strap mechanism of claim 1, wherein a hook is formed on the first rail for engaging inside an opening on the cage, and the strap is for providing the component force in the second direction so as to separate the hook from the opening on the cage.

8. The strap mechanism of claim 1, wherein the strap is made of elastic material.

9. The strap mechanism of claim 1 further comprising:

a second rail comprising;

a second locking part for connecting with another lateral surface of the electronic device and disposed inside the cage in the slidable manner; and

a second handle part connected to an end of the second locking part, a second slot being formed on the second handle part;

wherein a second end of the strap is inserted inside the second slot, the strap is for contacting against the second handle part so as to provide the component force in the first direction and in the second direction perpendicular to the first direction to the second handle part when the deformation of the strap is generated by being pulled in the first direction.

10. A removable storage module comprising:

an electronic device;

a cage for holding the electronic device; and

a strap mechanism connected to the electronic device and for pulling the electronic device out of the cage in a first direction, the strap mechanism comprising;

a first rail comprising;

a first locking part for connecting with a lateral surface of the electronic device and disposed inside the 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; and

a strap, a first end of the strap being inserted inside the first slot, the strap being for contacting against the first handle part so as to provide a component force in the first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the strap is generated by being pulled in the first direction, the strap comprising;

a strap body, a width of the strap body being larger than a width of the first slot;

a passing part connected to the strap body and for passing through the first slot, a width of the passing part being smaller than the width of the first slot, and a width in a middle of the first slot being larger than a width of two ends of the first slot so as to provide a space to rotate the passing part; and

a wedging part connected to the passing part, a width of the wedging part being larger than the width of the first slot so that the passing part passes through the first slot and the strap body and the wedging part are respectively installed on two sides of the first handle part.

11. The removable storage module of claim 10, wherein the strap mechanism further comprises at least one positioning component for positioning the first locking part on the lateral surface of the electronic device.

12. The removable storage module of claim 11, wherein the positioning component is a pin, an end of the pin is fixed on the first locking part, and another end of the pin is for inserting into a hole on the lateral surface of the electronic device.

13. The removable storage module of claim 10, wherein the strap mechanism further comprises an elastic component connected to the first locking part and disposed between the first locking part and the cage.

14. The removable storage module of claim 10, wherein a plurality of restraining components is formed on the first handle part and respectively disposed on two sides of the first slot for restraining a movement of the first end of the strap.

15. The removable storage module of claim 10, wherein a hook is formed on the first rail for engaging inside an opening on the cage.

16. The removable storage module of claim 10, the strap mechanism further comprises:

a second rail comprising;

a second locking part for connecting with another lateral surface of the electronic device and disposed inside the cage in the slidable manner; and

a second handle part connected to an end of the second locking part, a second slot being formed on the second handle part;

wherein a second end of the strap is inserted inside the second slot, the strap is for contacting against the second handle part so as to provide the component force in the first direction and in the second direction perpendicular to the first direction to the second handle part when the deformation of the strap is generated by being pulled in the first direction.
