Description

FIELD

The present disclosure relates to accessories of electronic device, particularly to a protection case for an electronic device.

BACKGROUND

The development of electronic devices has dramatically increased over the past decade, resulting in many new genres of battery-powered products such as so-called “smart phones,” or electronic readers. All such devices are relatively lightweight and portable, owing to the miniaturization of electronic components and circuitry. As opposed to carrying the phones in pockets, many people today use lanyards or cords to keep their phones in close proximity so that they may answer calls quickly.

Several definitions that apply throughout this disclosure will now be presented.

The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The present disclosure is described in relation to a protection case for an electronic device including a body shaped to receive and hold the electronic device, and a cover. A space is defined between the cover and the body, and an opening is defined in the cover. A lanyard passes through the opening and is partly received in the space, and an elastic element is accommodated in the space. The lanyard includes a first end fixed to the protection case, and a second end connecting to the lanyard.

FIGS. 1, 2 and 3 illustrate a protection case 100 for protecting an electronic device (not shown). The protection case 100 includes a body 10 and a lanyard 40. The lanyard 40 can be substantially circular in shape and can be elastic, although it does not need to be elastic. The body 10 is shaped to receive the electronic device. The body 10 includes a base panel 11 and a number of first side walls 12 surrounding and connected to the base panel 11, thereby forming a first space 13. The electronic device can be held in the first space 13. In this embodiment, the body 10 is substantially rectangular shaped, and includes four first side walls 12. At least one aperture 15 is defined in at least one of the first side walls 12 of the protection case 100. The at least one aperture 21 is configured to receive at least one button (not shown) of the electronic device. In an embodiment, the base panel 11 and the first side walls 12 are integrally formed together via an injection molding process.

FIG. 3 illustrates that the protection case 100 further includes a cover 30 coupled to an exterior periphery of the body 10. A second space 33 is formed between the cover 30 and the base panel 11.

In this embodiment, the second space 33 and the first space 13 are respectively located at two opposite sides of the base panel 11. In other embodiments, the second space 33 and the first space 13 can be respectively located at two opposite sides of one of the first side walls 12.

In this embodiment, the cover 30 is also substantially rectangular shaped corresponding to the body 10, and the cover 30 includes a panel 31 and a number of second side walls 32 surrounding and connected to the panel 31. The second side walls 32 are attached to the base panel 11. The second space 33 is surrounded by the panel 31, the second side walls 32 and the base panel 11.

FIGS. 1 and 2 illustrate that the protection case 100 further includes a coil spring 50, a button 60 and an elastic portion 70. The coil spring 50 is accommodated in the second space 33, the coil spring 50 includes a first end 51 located at a center of the coil spring 50, and a second end 52 located at a circumference of the coil spring 50. A fixing portion 34 is arranged on a surface 311 of the panel 31; the first end 51 of the coil spring 50 is fixed to the fixing portion 34. In this embodiment, the fixing portion 34 is a protrusion or a boss.

At least one opening 321 is defined in the second side wall 32, one end of the lanyard 40 passes through the opening 321 and is fastened to the second end 52 of the coil spring 50, the another end of the lanyard 40 is kept out of the protection case 100.

In this embodiment, two openings 321 are defined in one second side wall 32, the lanyard 40 is substantially circular formed by a cord connected head to tail. The head and the tail of the lanyard 40 pass through the two openings 321 respectively, and both are fastened to the second end 52 of the coil spring 50, to form a loop. In another manner, when the head and the tail of the lanyard 40 respectively pass through the two openings 321, the head of the lanyard 40 can be tied to the tail of the lanyard 40, then connect to the second end 52 of the coil spring 50 to finish the assembly.

FIG. 4 illustrates a button 60 of the protection case 100. The button 60 includes a button body 61 and a stopper portion 62, the diameter of the button body 61 is smaller than the diameter of the through hole 35; the diameter of the stopper portion 62 is larger than the diameter of the through hole 35. The button body 61 includes a third end 611 and a fourth end 612 opposite to the first end 51. The stopper portion 62 is connected to the fourth end 612. In this embodiment, the button body 61 is substantially cylinder shaped, and the stopper portion 62 is a flange extending from the fourth end 612. In other embodiments, the stopper portion 62 can be a protrusion protruding from a lateral surface of the fourth end 612.

FIGS. 2, 3 and 4 illustrate that a through hole 35 is arranged adjacent to the opening 321 on the panel 31 of the cover 30. The button 60 is accommodated in the second space 33, and the third end 611 of the button extends out of the protection case 100 in part, via the through hole 35. The stopper portion 62 is configured to stop the button 60 from dropping out of the through hole 35. In details, because of the diameter of the stopper portion 62 is larger than the diameter of the through hole 35, the stopper portion 62 prevents the button 60 from dropping out of the through hole 35.

The elastic portion 70 is held between the button 60 and the body 10. In this embodiment, the elastic portion 70 is a spring with an end resisting the button 60 and another end resisting the body 10. The button 60 further includes a recess 63 defined in the fourth end 612 to receive the spring 70.

The lanyard 40 is sandwiched between the stopper portion 62 and the surface 311 of the panel 31. In this embodiment, the lanyard 40 is circular, and the button body 61 is arranged in the loop formed by the lanyard 40.

Usually, when the lanyard 40 is unused, most of the lanyard 40 is received in the second space 33 under the force of the coiling spring 50.

When the button 60 is pressed, the space between the stopper portion 62 and the surface 311 of the cover 30 is increased, therefore the lanyard 40 is released. The lanyard 40 can be pulled to extend out of the protection case 100, and the coil spring 35 is stretched. When the force applied on the button 60 is removed, the stopper portion 62 moves toward to the surface 311 of the cover 30 under restoring force of the elastic portion 70 to sandwich the lanyard 40 again. User can get an appropriate length of the lanyard 40 via pressing the button 60 and lock the lanyard 40 by releasing the button 40.

When the button 60 is pressed as the coil spring 35 is being stretched; most of the lanyard 40 is automatically drawn into the second space 33.

In other embodiments, the coil spring 50 can be other elastic elements, such as a cylindrical helical spring having an end fixed on the protection case 100 and another end connected to the lanyard 40.
