Protective cases for mobile electronic devices and related methods
A protective case for a mobile electronic device may comprise a first frame member, a second frame member, and a first lap joint configured for joining the first frame member to the second member. An aperture may extend through the first lap joint and a pin may be sized and configured for positioning within the aperture and locking the lap joint together. Additionally, an elastic material may be sized and configured for positioning between the pin and a wall defining a portion of the aperture, the elastic material being elastically compressed between the wall and the pin when the pin is positioned within the aperture.
1. A method of providing a protective case for a mobile electronic device, the method comprising:
overlapping fingers extending from respective ends of a first frame member and a second frame member, the first frame member comprising a first aperture and a second aperture, the first and second apertures being aligned with each other, the first aperture having a first inner diameter, the second aperture having a second inner diameter, the first inner diameter being different than the second inner diameter, the second frame member comprising a third aperture;
coaxially aligning the first, second, and third apertures of the first and second frame members within the fingers of the first and second frame members;
applying an axial force to a first pin and pushing the first pin into the first, second, and third apertures with the axial force, the first pin comprising a first axial region having a first axial region diameter and a second axial region having a second axial region diameter, the first axial region diameter being different than the second axial region diameter, the first axial region being positioned in the first aperture and the second axial region being positioned in the second and third apertures; and
compressing an elastic material between a radially internal surface of the first aperture and the first axial region of the first pin.
2. The method of claim 1 , further comprising positioning the elastic material within a circumferentially extending recess of the first pin.
3. The method of claim 2 , wherein positioning the elastic material at least partially within the circumferentially extending recess of the first pin comprises positioning an O-ring at least partially within the circumferentially extending recess of the first pin.
4. The method of claim 1 , further comprising applying the axial force to the first pin manually and without a tool.
5. The method of claim 1 , further comprising:
overlapping fingers extending from respective ends of a third frame member and a fourth frame member;
coaxially aligning apertures within the fingers of the third frame member and fourth frame member;
applying an axial force to a second pin and pushing the second pin into the coaxially aligned apertures of the fingers of the third frame member and fourth frame member; and
compressing an elastic material between a wall of an aperture of the coaxially aligned apertures of the fingers of the third frame member and fourth frame member and the second pin.
6. The method of claim 5 , further comprising removing the protective case from the mobile electronic device by:
removing the first pin from the coaxially aligned apertures of the fingers of the first frame member and second frame member by applying an axial force to the first pin with a tip of a fine-tipped instrument, the tip being configured to push the first or second pin through the coaxially aligned apertures; and
removing the second pin from the coaxially aligned apertures of the fingers of the third frame member and fourth frame member by applying an axial force to the second pin with the tip of the fine-tipped instrument.
7. The method of claim 6 , wherein:
applying the axial force to the first pin with the tip of the fine-tipped instrument comprises applying the axial force to the first pin with at least one of a toothpick, a paper clip, and a ball-point pen; and
applying the axial force to the second pin with the tip of the fine-tipped instrument comprises applying the axial force to the second pin with at least one of a toothpick, a paper clip, and a ball-point pen.
