Abstract

The present disclosure provides an apparatus for adapting a first base to a double first base having a fielder base and a runner base. The apparatus may include a first plate. The first plate may define a top face, a bottom face, a first side, and a second side. The first plate may include an anchor aperture defined on the first side. The anchor aperture may be shaped to receive a ground anchor of a fielder base. The second side may be configured to be secured to a runner base. The first plate may further include one or more teeth protruding from the bottom face on the second side. The anchor aperture may be shaped such that the first plate mechanically engages and resists angular movement of the ground anchor relative to the first plate.

Claims (47)

1 . An apparatus for adapting a first base to a double first base having a fielder base and a runner base, the apparatus comprising:

a first plate defining a top face, a bottom face, a first side, and a second side, the first plate including an anchor aperture defined on the first side,

wherein the anchor aperture is shaped to receive a ground anchor of a fielder base advanced through the anchor aperture, and

wherein the second side is configured to be secured to a runner base.

2 . The apparatus of claim 1 , wherein the anchor aperture is shaped such that the first plate mechanically engages and resists angular movement of the ground anchor relative to the first plate.

3 . The apparatus of claim 1 , wherein the first plate further includes a first one or more connection apertures defined on the second side, and

wherein the first one or more connection apertures are shaped to receive a first one or more fastening elements, the first one or more fastening elements configured to mechanically engage the runner base.

4 . The apparatus of claim 3 , wherein the first one or more connection apertures are distributed in a square pattern.

5 . The apparatus of claim 3 , wherein the first plate further includes a second one or more connection apertures defined on the first side, and

wherein the second one or more connection apertures are shaped to receive a second one or more fastening elements, the second one or more fastening elements configured to mechanically engage the fielder base.

6 . The apparatus of claim 1 , wherein the first plate further includes one or more teeth protruding from the bottom face on the second side.

7 . An apparatus for adapting a first base to a double first base having a fielder base and a runner base, the apparatus comprising:

a first plate defining a top face, a bottom face, a first side, and a second side, the first plate including an anchor aperture defined on the first side; and

a runner base disposed above and secured to the second side,

wherein the anchor aperture is shaped to receive a ground anchor of a fielder base advanced through the anchor aperture.

8 . The apparatus of claim 7 , further comprising a second plate disposed between the first plate and the runner base, the second plate secured to the second side of the first plate and the runner base.

9 . The apparatus of claim 7 , wherein the anchor aperture is shaped such that the first plate mechanically engages and resists angular movement of the ground anchor relative to the first plate.

10 . The apparatus of claim 7 , wherein the first plate further includes a first one or more connection apertures defined on the second side, and

wherein the first one or more connection apertures are shaped to receive a first one or more fastening elements, the first one or more fastening elements configured to mechanically engage the runner base, such that the first plate is secured to the runner base.

11 . The apparatus of claim 10 , wherein the first one or more connection apertures of the first plate are distributed in a square pattern.

12 . The apparatus of claim 11 , wherein the first plate further includes a second one or more connection apertures defined on the first side, and

wherein the second one or more connection apertures are shaped to receive a second one or more fastening elements, the second one or more fastening elements configured to mechanically engage the fielder base, such that the first plat is secured to a fielder base.

13 . The apparatus of claim 12 , wherein the second one or more connection apertures are slots.

14 . The apparatus of claim 7 , wherein the first plate further includes one or more teeth protruding from the bottom face on the second side.

15 . The apparatus of claim 7 , wherein the anchor aperture is shaped such that the first plate mechanically engages and resists angular movement of the ground anchor relative to the first plate.

16 . A method of adapting a first base to a double first base having a fielder base and a runner base, the method comprising:

providing a first plate defining a top face, a bottom face, a first side, and a second side, the first plate including an anchor aperture defined on and vertically extending through the first side;

securing a runner base to the second side;

advancing a ground anchor of a first base through the anchor aperture; and

inserting the ground anchor into a ground surface.

17 . The method of claim 16 , wherein the anchor aperture is shaped such that the first plate mechanically engages and resists angular movement of the ground anchor relative to the first plate.

18 . The method of claim 16 , wherein securing the runner base to the second side of the first plate includes:

securing a second plate to the second side; and

securing the second plate to the runner base.

19 . The method of claim 16 , wherein securing the runner base to the second side further includes:

advancing a first one or more fastening elements through a first one or more connection apertures defined on the second side of the first plate; and

mechanically engaging the runner base with the one or more fastening elements.

20 . The method of claim 16 , wherein the first plate further includes one or more teeth protruding from the bottom face on the second side.

21 . An apparatus, comprising:

a fielder base including an anchor post;

a flat adapter plate disposed below the fielder base, the adapter plate having a first side positioned under the fielder base and a second side extending away from the fielder base;

an anchor aperture defined through the first side of the adapter plate, wherein the anchor post extends downwardly from the fielder base through the anchor aperture; and

a runner base disposed on the second side of the adapter plate beside the fielder base.

22 . The apparatus of claim 21 , wherein the anchor post extending downwardly through the anchor aperture includes a rectangular cross-sectional profile, and the anchor aperture defines a corresponding rectangular cross-sectional profile such that the adapter plate mechanically engages the anchor post.

23 . The apparatus of claim 22 , wherein the engagement between the anchor post and the adapter plate via the anchor aperture resists angular movement of the adapter plate relative to the anchor post when the adapter plate is attached to the anchor post.

24 . The apparatus of claim 23 , wherein the adapter plate further comprises a plurality of spikes extending downwardly from the second side of the adapter plate below the runner base.

25 . The apparatus of claim 24 , further comprising a concrete base having an anchor sleeve disposed below the fielder base, wherein the anchor post extends downwardly from the fielder base through the anchor aperture of the adapter plate and engages the anchor sleeve.
