Abstract

In certain embodiments, a mounting apparatus includes one or more standoffs adapted to maintain two panels at a spaced apart distance from one another. The standoff includes a first end having a first threaded fastening member and a second end having a cavity in which a torque restraining member is disposed. The torque restraining member is coupled to a second threaded fastening member. The relative sizes of the torque restraining member and the cavity allow movement of the torque restraining member within the cavity.

Claims

1. A mounting apparatus comprising:

a standoff having an axis, a first end comprising a first threaded fastening member, and a second end comprising a cavity, wherein the first threaded fastening member comprises male threads configured to engage female threads of a nut; and

a second threaded fastening member coupled to a torque restraining member that is entrapped in the cavity such that the torque restraining member cannot move out of the cavity, wherein the second threaded fastening member is contained within the cavity and comprises female threads operable to engage male threads of a bolt, wherein the female threads of the second threaded fastening member extend through an interior portion of the torque restraining member;

wherein relative sizes of the torque restraining member and the cavity define a space that is configured to (i) allow a linear movement of the torque restraining member within the cavity and (ii) restrict the first threaded fastening member from rotating relative to the second threaded fastening member, the linear movement defined as movement of the torque restraining member in a lateral direction relative to the axis of the standoff; and

wherein the relative sizes of the torque restraining member and the cavity allow at least 0.030 inches of the linear movement of the torque restraining member.

2. The mounting apparatus of claim 1, wherein the torque restraining member and the cavity have a square-shaped periphery along their lateral extent relative to the axis of the standoff.

3. The mounting apparatus of claim 1, wherein the standoff comprises a notch extending around a portion of its periphery proximate the first threaded fastening member.

4. The mounting apparatus of claim 1, wherein:

the space is also configured to allow a second linear movement of the torque restraining member within the cavity, the second linear movement defined as movement of the torque restraining member in a parallel direction relative to the axis of the standoff, and

the standoff comprises a lip that extends around a periphery of the cavity and limits an extent of the second linear movement.

5. The mounting apparatus of claim 1, wherein the torque restraining member and the second threaded fastening member are integrally formed of one or more of:

plastic or metal.

6. The mounting apparatus of claim 1, wherein at least one of the first threaded fastening member and the second threaded fastening member comprises at least one self-locking thread.

7. A mounting system comprising:

a plurality of standoffs; and

an array of torque restraining components, each torque restraining component having at least one restraining surface and a hole, the array of torque restraining components adapted to;

engage the plurality of standoffs;

wherein each standoff comprises;

a base having;

an axis;

a first end comprising a first threaded fastening member, the first threaded fastening member comprising male threads configured to engage female threads of a nut; and

a second end comprising a cavity; and

a second threaded fastening member coupled to a torque restraining member that is entrapped in the cavity such that the torque restraining member cannot move out of the cavity, the second threaded fastening member contained within the cavity and comprising female threads operable to engage male threads of a bolt, the female threads of the second threaded fastening member extending through an interior portion of the torque restraining member;

wherein, in each standoff, relative sizes of the torque restraining member and the cavity define a space that is configured to (i) allow a linear movement of the torque restraining member within the cavity and (ii) restrict the first threaded fastening member from rotating relative to the second threaded fastening member, the linear movement defined as movement of the torque restraining member in a lateral direction relative to the axis of the standoff, wherein the relative sizes of the torque restraining member and the cavity allow at least 0.030 inches of the linear movement of the torque restraining member.

8. The mounting system of claim 7, wherein the array of torque restraining components are integrally formed with a chassis.

9. The mounting system of claim 7, wherein the array of torque restraining components are mounted to a chassis using a physical coupling technique comprising one or more of:

riveting, welding, brazing, swaging, press-fitting, soldering, and screwing.

10. The mounting system of claim 7, wherein the at least one restraining surface of each torque restraining component comprises an outer edge having a chamfered shape.

11. The mounting system of claim 7, wherein the at least one restraining surface of each torque restraining component comprises six walls having a hexagonal shape that extends around the hole of the torque restraining component.

12. The mounting system of claim 7, wherein:

at least one of the torque restraining components has a single restraining surface;

others of the torque restraining components have two restraining surfaces forming troughs for insertion of their respective standoffs; and

the single restraining surface of the at least one torque restraining component is perpendicular to the restraining surfaces of the other torque restraining components.

19. The mounting system of claim 7, wherein the torque restraining member and the cavity in each standoff have a square-shaped periphery along their lateral extent relative to the axis of that standoff.

20. The mounting system of claim 7, wherein each standoff comprises a notch extending around a portion of its periphery proximate the first threaded fastening member of that standoff.

13. A method comprising:

engaging, on an array of torque restraining components, a corresponding plurality of standoffs, each torque restraining component having at least one restraining surface; and

inserting or removing screws to or from, respectively, the plurality of standoffs through holes associated with the array of torque restraining components, each of the plurality of standoffs being restricted from rotating by abutment of its surface with the at least one restraining surface of its respective torque restraining component;

wherein each standoff comprises;

a base having;

an axis;

a first end comprising a first threaded fastening member, the first threaded fastening member comprising male threads configured to engage female threads of a nut; and

a second end comprising a cavity; and

a second threaded fastening member coupled to a torque restraining member that is entrapped in the cavity such that the torque restraining member cannot move out of the cavity, the second threaded fastening member contained within the cavity and comprising female threads operable to engage male threads of a bolt, the female threads of the second threaded fastening member extending through an interior portion of the torque restraining member;

wherein, in each standoff, relative sizes of the torque restraining member and the cavity define a space that is configured to (i) allow a linear movement of the torque restraining member within the cavity and (ii) restrict the first threaded fastening member from rotating relative to the second threaded fastening member, the linear movement defined as movement of the torque restraining member in a lateral direction relative to the axis of the standoff, wherein the relative sizes of the torque restraining member and the cavity allow at least 0.030 inches of the linear movement of the torque restraining member.
