Abstract

An apparatus, having an elongated main body ( 102 ) with a dovetail shape, a top surface ( 104 ), a bottom surface ( 106 ), a side surface ( 108 ) connecting the top surface and the bottom surface, a first end ( 120 ), a second end ( 122 ), and a chamfer ( 124 ) at a corner ( 126 ) of the side surface and the bottom surface at the first end. A size and shape of the elongated main body matches a size and shape of a frustoconical section ( 520 ) of a dovetail slot into which the elongated main body slip fits. A bottom ( 522 ) of the frustoconical section is spaced apart from a bottom of the dovetail slot.

Claims (25)

1. An apparatus, comprising:

a main body comprising a dovetail shape, a top surface, a bottom surface, a side surface connecting the top surface and the bottom surface, a first end, a second end, and a chamfer at a corner of the side surface and the bottom surface at both the first end and the second end;

wherein the main body is elongated and configured to fit within a 0.4 inch deep dovetail slot comprising a ½ inch wide bottom and sidewalls that each taper inward at 14 degrees from a respective corner of the bottom, while being set apart from the bottom of the dovetail slot by a gap of at least 0.02 inches;

wherein the side surface comprises an oval shape comprising parallel side portions and rounded end portions;

wherein the rounded end portions are tapered inward from a top of the chamfer to the top surface; and

a female thread or a stud comprising a male thread and projecting vertically from the top surface.

2. The apparatus of claim 1 , wherein a length of the main body is at least one inch (1″).

3. The apparatus of claim 1 , wherein the chamfer extends fully around the main body.

4. The apparatus of claim 1 , wherein a length of the main body is at least twice a maximum width of the main body.

5. The apparatus of claim 1 , comprising the stud, wherein the stud is disposed at a middle of the main body.

6. The apparatus of claim 1 , wherein a width of the main body is 0.44 inches to 0.46 inches and a length of the main body is at least twice the width of the main body.

7. The apparatus of claim 1 , wherein the chamfer comprises a chamfer height of 0.025 inches to 0.030 inches.

8. The apparatus of claim 1 , further comprising the stud and a nut fastener configured to cooperate with the stud.

9. An apparatus, comprising:

an elongated main body comprising a dovetail shape, a top surface, a bottom surface, a side surface connecting the top surface and the bottom surface, a rounded first end, a rounded second end, and a chamfer at a corner of the side surface and the bottom surface that extends fully around the elongated main body;

a stud comprising a male thread projecting vertically from the top surface;

wherein the elongated main body is configured to fit entirely within a 0.4 inch deep dovetail slot comprising a ½ inch wide bottom and sidewalls that each taper inward at 14 degrees from a respective corner of the bottom while being set apart from the bottom of the dovetail slot by a gap of at least 0.02 inches;

wherein the side surface comprises a first side portion that extends parallel to and opposite a second side portion, a first end portion comprising a first radiused shape that is radiused about a first axis that bisects the dovetail shape, wherein the first radiused shape is directly connected to the first side portion to the second side portion, and a second end portion comprising a second radiused shape that is radiused about a second axis that bisects the dovetail shape, wherein the second radiused shape is directly connected to the first side portion to the second side portion;

wherein the first radiused shape and the second radiused shape are tapered inward from a top of the chamfer to the top surface, and

wherein a length of the elongated main body is at least twice a width of the elongated main body.

10. The apparatus of claim 9 , wherein the length of the elongated main body is at least one inch (1″).

11. The apparatus of claim 9 , wherein the stud is disposed at a middle of the elongated main body.

12. The apparatus of claim 9 , wherein the width of the elongated main body is 0.44 inches to 0.46 inches.

13. The apparatus of claim 9 , wherein the chamfer comprises a chamfer height of 0.025 inches to 0.030 inches.

14. The apparatus of claim 9 , further comprising a nut fastener configured to cooperate with the stud.
