Abstract
A system configured to anchor a cover plate over an interface formed between substantially coplanar substrates includes a sleeve capable of being anchored in a first substrate; a spring located in the sleeve; a post located in communication with the spring; and a fastener secured onto the post. A head of the post is located in the sleeve, and an end of the post opposite the head of the post extends out of the sleeve to receive the fastener. The fastener is secured onto the post over the cover plate located on the first substrate such that the cover plate extends over the interface formed between the first and second substrates when they are positioned to be substantially coplanar.
Claims16
A system configured to anchor a cover plate over an interface formed between a first substrate and a second substrate which are substantially coplanar with each other, the system comprising:
- a sleeve comprising a center channel and anchorable in the first substrate, wherein the sleeve has a first end and a second end;
- a collar comprising a pin, wherein the center channel of the sleeve receives the collar;
- a spring located in the sleeve and positioned on the collar;
- a post located in communication with the spring, the post configured to screw down into the collar through the spring to effect a tightening of the system, wherein a lower end of the post is received in the sleeve and an upper end of the post comprises a hemispherical head extending out of the sleeve and configured to be received in an opening in the cover plate;
- a first end stop configured to attach to the first end of sleeve;
- and
- a second end stop configured to attach to the second end of the sleeve, the second end stop comprising a center channel which receives the post.
A covering system configured to cover a gap between a first substrate and a second substrate which are substantially coplanar with each other, the covering system comprising:
- a cover plate locatable over the gap defined between the first substrate and the second substrate substantially coplanar with the first substrate;
- and an anchoring system configured to anchor the cover plate over the gap, the anchoring system comprising:
- a sleeve comprising a center channel and anchorable in the first substrate, wherein the sleeve has a first end and a second end;
- a collar comprising a pin, wherein the center channel of the sleeve receives the collar;
- a spring located in the sleeve and positioned on the collar;
- a post located in communication with the spring, the post configured to screw down into the collar through the spring to effect a tightening of the anchoring system, wherein a lower end of the post is received in the sleeve and an upper end of the post comprises a hemispherical head extending out of the sleeve and configured to be received through an opening in the cover plate;
- a first end stop configured to attach to the first end of sleeve;
- and
- a second end stop configured to attach to the second end of the sleeve, the second end stop comprising a center channel which receives the post such that the hemispherical head of the post is configured to rest on a portion of the cover plate.
An anchor configured to anchor a cover plate over a gap formed between a first substrate and a second substrate which are substantially coplanar with each other, the anchor comprising:
- a sleeve comprising a center channel and anchorable in the first substrate, wherein the sleeve has a first end and a second end;
- a collar comprising a pin, wherein the center channel of the sleeve receives the collar;
- a spring located in the sleeve and positioned on the collar;
- a post located in communication with the spring, the post configured to screw down into the collar through the spring to effect a tightening of the anchoring system, wherein a lower end of the post is received in the sleeve and an upper end of the post comprises a hemispherical head extending out of the sleeve and configured to be received through an opening in the cover plate;
- a first end stop configured to attach to the first end of sleeve;
- and
- a second end stop configured to attach to the second end of the sleeve, the second end stop comprising a center channel which receives the post.
A method of anchoring a cover plate over a gap formed between a first substrate and a second substrate which are substantially coplanar with each other, the method comprising:
- locating the cover plate over the gap defined between the first substrate and the second substrate substantially coplanar with the first substrate;
- providing an anchoring system in the first substrate to anchor the cover plate over the gap, the anchoring system comprising:
- a sleeve comprising a center channel, the sleeve being anchored in the first substrate, wherein the sleeve has a first end and a second end;
- a collar comprising a pin, wherein the center channel of the sleeve receives the collar;
- a spring located in the sleeve and positioned on the collar;
- a post located in communication with the spring, wherein a lower end of the post is received in the sleeve and an upper end of the post comprises a hemispherical head extending out of the sleeve and received in an opening in the cover plate;
- a first end stop attached to the first end of sleeve;
- and
- a second end stop attached to the second end of the sleeve, the second end stop comprising a center channel which receives the post such that the hemispherical head of the post rests on a portion of the cover plate;
- and
- tightening the post to screw the post down into the collar through a portion of the cover plate and through the spring to effect a tightening of the anchoring system.
