Abstract

The present invention is an anchoring biscuit device for joining three boards. It includes, (a) an at least partially flat horizontal top element having an imaginary center line, having opposite side walls, and having a top view footprint adapted to be inserted into grooves of adjacent boards; (b) at least one substantially vertical support member attached to the underside of the top element and extending downwardly therefrom for a predetermined length for joinder of two adjacent boards which contain the grooves for receiving portions of the top into the grooves; and (c) at least one compressive element located on the device, with at least one portion of the at least one compressive element, from a top view footprint, being located away from the imaginary center line and away from the vertical support member, wherein the compressive element is adapted to at least partially collapse under a predetermined compressive force.

Claims

1. An anchoring device comprising:

a horizontally-extending top element having a center line and side portions extending from the center line in opposite lateral directions transverse to the center line;

a support member extending downwardly from the top element adjacent the center line, the side portions of the top element projecting in the lateral directions beyond the support member; and

one or more at least partially collapsible compression members projecting from the top element, the compression members defining engagement surfaces remote from the center line, the engagement surfaces being constructed and arranged to confront vertically-extensive surfaces of slotted boards engaged with the top element so that the top element extends into slots in the boards;

the anchoring device having an opening adapted to receive a fastener so that the fastener extends downwardly toward a joist.

2. The anchoring device according to claim 1, wherein the horizontally-extending top element has a shape selected from the group consisting of square, rectangular, circular, and oval.

3. The anchoring device according to claim 1, wherein the opening extends through the horizontally top element.

4. The anchoring device according to claim 1, wherein the opening is located adjacent the center line of the horizontally-extending top element.

5. The anchoring device according to claim 1, wherein the one or more compression members are attached to the support members.

6. The anchoring device according to claim 1, wherein the one or more compression members includes one or more hollow cylinders.

7. The anchoring device according to claim 1, wherein the one or more compression members include one or more fins projecting from the top element.

8. The anchoring device according to claim 1, wherein the support member includes at least two planar structures spaced from each other, the at least two planar structures being positioned substantially along a single plane.

9. The anchoring device according to claim 1, wherein the support member is a monolithic structure.

10. The anchoring device according to claim 1, wherein the opening has an elongated shape.

11. An decking system comprising:

at least two slotted boards adjacent to each other, each slotted board including a slot and at least one vertically-extensive surface and at least one horizontally-extensive surface; and

an anchoring device having an opening adapted to receive a fastener so that the fastener extends downwardly toward a joist, the anchoring device comprising;

a horizontally-extending top element having a center line and side portions extending from the center line in opposite lateral directions transverse to the center line;

a support member extending downwardly from the top element adjacent the center line, the side portions of the top element projecting in the lateral directions beyond the support member; and

one or more at least partially collapsible compression members projecting from the top element, the compression members defining engagement surfaces remote from the center line, the engagement surfaces being constructed and arranged to confront the at least one vertically extensive surface of each slotted board engaged with the top element so that the top element extends into the slots in the boards.

12. The decking system according to claim 11, wherein the horizontally-extending top element has a shape selected from the group consisting of square, rectangular, circular, and oval.

13. The decking system according to claim 11, wherein the opening extends through the horizontally top element.

14. The decking system according to claim 11, wherein the opening is located adjacent the center line of the horizontally-extending top element.

15. The decking system according to claim 11, wherein the one or more compression members are attached to the support members.

16. The decking system according to claim 11, wherein the one or more compression members includes one or more hollow cylinders.

17. The decking system according to claim 11, wherein the one or more compression members include one or more fins projecting from the top element.

18. The decking system according to claim 11, wherein the support member includes at least two planar structures spaced from each other, the at least two planar structures being positioned substantially along a single plane.

19. The decking system according to claim 11, wherein the support member is a monolithic structure.

20. The decking system according to claim 11, wherein the opening has an elongated shape.

21. An anchoring device comprising:

a horizontally-extending top element having a center line, side portions extending from the center line in opposite lateral directions transverse to the center line, opposite sidewalls and opposite end walls, the center line extending between the opposite end walls, at least a portion of one of the end walls being non-parallel relative to a corresponding portion of the other end wall directly opposite thereto;

a support member extending downwardly from the top element adjacent the center line, the side portions of the top element projecting in the lateral directions beyond the support member, the support member being constructed and arranged to be positioned between vertically-extensive surfaces of slotted boards engaged with the top element so that the top element extends into slots in the boards; and

the anchoring device having an opening adapted to receive a fastener so that the fastener extends downwardly toward a joist.

22. The anchoring device according to claim 21, wherein at least one of the opposite end walls has an arc-shape.

23. The anchoring device according to claim 21, further comprising one or more compression members projecting from the horizontally-extending top element.

24. The anchoring device according to claim 23, wherein the one or more compression members have an oval cross-section.

25. The anchoring device according to claim 21, wherein the opening has a beveled top.
