BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates to fasteners and more specifically to fasteners which provide adjustments in the use thereof.

Description of Related Art

Currently, there are several solutions to attach two or more pieces together but they do not allow to make changes in the level or height of one piece relative to the other without losing support and grip. Some of these solutions attempt leveling or height adjustments through introduction of small pieces for example as wood shims or other material that could fill the gap between the pieces to keep them separated and give them the required level but this is very time consuming and in many cases is not practical or possible to do, due to the impossibility or undesirability to access the back part of the piece. In many cases and the only way to reach the back of a panel to put an object behind the panel is to open a hole or make a cut in the piece or panel. These solutions fail to meet the needs of the industry because as was mentioned before they take much material are time consuming and required a certain level of skill to do.

Therefore, what is clearly needed is fastener and a method that solves the problems and deficiencies mentioned above.

SUMMARY OF THE INVENTION

It is desirable to have a fastener device that allows the user to make adjustments of level and position of various pieces without losing the attachment and grip of the piece to the structure or to the other piece, thus helping to quickly and easy obtain required leveling from each piece, joint leveling or other uses that requires the adjustments of level. The problem that this invention solves apply in situations such as: installations of panels, logs adjustment, seams and joints leveling, bones leveling and adjustments of positions and any other leveling need situations when various attached pieces. In many of these situation its not possible or desired to access the back part of the panel or piece, even when time is a crucial factor and the user needs to adjust the height for joints matching or other leveling requirements fast and securely. The current fasteners available just let the pieces stay together through adjacency and compression not permitting the user to separate pieces or adjust level without losing compression, thus loosing grip or attachment. The disclosed fastener device and associated method advantageously fill these need and addresses the aforementioned deficiencies by providing a fastener that through a locking system that makes the panels or pieces stay at certain desired height of the fastener allows the part of the fastener that its not blocking the panel or piece to continue work in its path to adjust height both up or down as the user requires. When obtaining the desired point or height of the panel or piece. The user have the possibility if required to inject through an internal channel that extends throughout the interior of the fastener a liquid for a definitive connection of the panel or pieces or any other material required to inject as the application requires.

Disclosed is a system together with an associated mechanical process. The system is made up of a fastener body comprised by a Fastener head with Phillips or other required screwdriver shape and body thread, flat body, internal liquid channel holes for liquid and height channels for extendable arms. The system includes extendable retractable arms. The body of the fastener have height channels in which the expandable retractable arms rest and are attached. This channel is located in the middle upper narrower without thread part of the fastener and delimitate a track for the expansion or contraction of the expandable retractable arms. The thread, the internal channel for materials, side recess holes for material expulsion through the internal channel, screw head and a serrated flange. The materials for the manufacturing of the fastener could vary depending on the application for which will be used as well as the distance and the size of the components. Some of the materials that can be used to manufacture the fastener could be but are not limited to are as example: Metals, Polymers, Ceramics, Composites, etc.

The system may also have one or more of the following components: dented flange washer for added grip, a protective cap for the retractable expandable arms for applications that require protection for the articulated arms and for the material on the back part of the piece, a fixed positioned washer channel in the fastener body, a flexible body attachment attached to the fastener body through a precision and thread mechanism, a pivotable and rotatable hinge, additional pivot point for the retractable arms for smaller gaps openings and a extra hole for material expulsion in the spring channel located in the fastener body.

The disclosed system is unique when compared with other known systems and solutions in that it provides a fastener that help the user to adjust level from two or more pieces and with its functions also permits to rotate and move its position without losing grip and attachment from one piece to the other, this help in many real situations life as example fascia leveling repairs, dry wall repairs, seams leveling, medical bone level adjustment and many other that require a fastener that holds and keep grip and let the user level and secured the pieces even when its impractical or impossible to access the back part of the piece also letting the user to insert liquids for multiple purposes.

The disclosed system is superior in that the overall architecture of the system is unique. More specifically, the system is unique due to the presence of the fastener blocked piece mechanism that hold in place the piece and let the fastener continue its way to the other piece to secure and leveled the height as desired by the user without having to access the back part of the pieces and also for insertion of liquids or other materials. This will lead in simplification and reduction of steps, money and time also getting a more secure way of leveling for users.

The present invention relates to a fastener device and a method associated with the device. The device holds various pieces together through a blocking mechanism which block one piece at certain desired height and allows the other part of the fastener that is not blocking to continue work in its path to adjust up or down the height as the user requires. When obtaining the desired point or height the user has the possibility if required or desired to inject through a internal channel such as used in a needle to inject liquids or materials for immobilization or for other applications required. This device fastener can be used for the need of leveling and adjusting two pieces such as panels, logs, pipes, bones or any other pieces that need to be leveled without losing attachment. The core components of the invention are, which are configured as follows: Fastener body and head with thread, internal channel and holes for internal channel, retractable arms. With respect to the associated method, In order to carry out the method the following core steps are followed: With a drill or a screw driver insert the fastener through the pieces that are desired to level, as the fastener pass the first piece the retractable arms will open holding and blocking from movement the first piece, the fastener will continue its path to the second piece going through the piece, the user at this moment will decide the height required, the user will inject through the channel of the fastener any liquid required or material. Ultimately, at the conclusion of these steps the fastener will allow to adjust the height of the pieces without losing attachment to the other piece or structure thus helping quickly obtaining the leveling of joints or other leveling needed adjustments between pieces and the spread of materials and liquid or pastes solutions easily through the fastener internal channel characteristic.
