A protective case for a handheld electronic device is provided. The protective case can include a removable mounting system comprised of an interlocking member and a plurality of mounting bases. The protective case may further include a non-slip member to prevent the device from slipping on a surface and a magnet for attaching the device to a magnetic surface.

The polygonal part (1) has, on each side (C1 to C6), at least one of the following assembly elements: at least one lug (3), at least one recess (4), each of said lugs (3) and each of said recesses (4) of the part (1) having a trapezoidal shape, with in each case complementary shapes, the trapezium of each of said lugs (3) widening towards the outside of the part (1) and the trapezium of each of said recesses (4) widening towards the inside of the part (1), and each of said lugs (3) having a width, defined transversely with respect to a right bisector of the corresponding trapezium, which is greater than the width of each of said recesses (4).

A coupling structure for vehicle chassis members couples a ball joint member and an axle housing used for a vehicle to each other. The structure includes a socket that has a substantially columnar external shape, is provided in the ball joint member, and has a socket bolt groove throughout a circumference in an outer circumferential surface of the socket. The structure also includes a collar that has a substantially cylindrical shape and is disposed so as to surround an outer circumferential surface of the socket. The axle housing has a coupling hole having a substantially columnar internal shape into which the socket is inserted. The ball joint member and the axle housing are coupled to each other by disposing the socket in the coupling hole while the socket is surrounded by the collar.

An assembly configured to limit movement of an apparatus having a base that rests on a surface includes a body member and a gate. The body member is configured to be secured to the surface and has an opening configured to receive the base of the apparatus. The gate is configured to be removably coupled with the body member to open and close the opening. When the gate is coupled with the body member, the gate is configured to cooperate with the body member to limit movement of the base of the apparatus relative to the surface in directions that are parallel to the surface.
