## Background
BACKGROUND OF THE INVENTION
The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.
1. Field of the Invention
The present invention relates generally to the field of flooring installation and more specifically relates to flooring setting systems.
2. Description of Related Art
Flooring is a general term for a semi-permanent covering of an unfinished surface of the ground, such as concrete or unfinished wood. Flooring generally includes tile, wood, laminate, and/or synthetic materials. Each type of flooring often requires a different method of installation. Some types of flooring require being affixed to the unfinished surface or sub-floor by adhesives (e.g., glue, epoxy, etc.).
Wood flooring and related trim pieces are often installed by the “glue-down” method which is often used when wood is placed upon a concrete or other solid surface. Also, wooden stairs and trim is often affixed by adhesive. In many instances, the unfinished surface/sub-floor may not be completely flat and/or level. Additionally, many natural wood products are sometimes not fully uniform and may have a bow or be prone to warping when adhesive is applied. Environmental factors such as heat or humidity may affect the gluing of the flooring materials to the sub-floor. Further, gluing or affixing wooden materials by adhesive often requires adequate and/or continuous pressure to ensure proper setting while the adhesive is curing and/or drying. Therefore a suitable solution is desired.
Several attempts have been made to solve the above-mentioned problems such as those found in US and Foreign Patent and Publication Numbers: U.S. Pat. No. 6,796,049 to Claxton; U.S. Pat. No. 6,047,520 to Caraballo; U.S. Pat. No. 5,867,965 to Pitz et al.; U.S. Pat. No. 6,772,564 to Leon; U.S. Pat. No. 3,643,992 to Jaccobucci; U.S. Pat. No. 4,091,945 to Patterson; U.S. Pat.

DETAILED DESCRIPTION
As discussed above, embodiments of the present disclosure relate to a flooring installation system and more particularly to a system for setting flooring transitions or floor-transition-setting system as used to improve the installation of construction material that may require the use of constant pressure for set-up and/or curing.
The present disclosure may offer significant improvements and serve as a floor-transition-setting system. Preferably, a flooring installation should provide a modular system with adequate pressure during setup and curing of adhesive, or other installation methods requiring constant and continued pressure during installation, while being configurable to a wide range of applications, and yet, would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable floor-transition-setting system to avoid the above-mentioned problems.
Generally speaking, a floor-transition-setting system includes at least one assembly, having an adjustable width and height, that is configured to press and hold down flooring items such as floor transitions, trims, strips, end caps and other constructed sections in place while being set. The floor-transition-setting system or assembly may be constructed with an adjustable width and height, adjustable tension, and various sizes and/or lengths. The floor-transition-setting system may further include padding to prevent damage pressure points, and is preferably easily adjustable to fit the needs of a user. Once adjusted, the floor-transition-setting system may apply setting pressure to a plurality of spaced or distributed points to hold the flooring materials in place while being set, and prevent movement or other disturbance during setting. Beneficially, such an arrangement may solve the problem of setting flooring items rising out of position or being disturbed while its adhesive is curing.
Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4 various views of a system for setting flooring transitions and flooring (floor-transition-setting system 100) in an “in use” condition 150. As illustrated, the floor-transition-setting system 100 may include a connector-body 102, a plurality of extension-bodies 110, a plurality of leg-members 118, and a plurality of pressure-feet 126.
By way of example, and with reference to FIG. 1A, here a simplified floor-transition-setting system 100 includes a first 90 degree assembly, having at least one vertical leg member 118 that is each adjustably coupled to a downward pressing pressure-foot 126 at a bottom end, and rotatably coupled to an extension-body 110 at a top end. The extension-body 110 is then adjustably coupled to a sideways pressing pressure-foot 126 at an outward side (90 degrees from the vertical leg member 118) of the extension-body 110. The simplified floor-transition-setting system 100 further includes a second 90 degree assembly that is substantially the same as the first assembly. The first and second assemblies are then toollessly coupled to each other's inner side, opposite their outer side, respectively, via a connector-body 102. Functionally, in this particular configuration, floor-transition-setting system 100 is arranged to be inserted in a door jamb and apply pressure to a door threshold (saddle). In particular, while the two sideways pressing pressure-feet 126 apply pressure to the door jamb, they acquire sufficient opposing normal force to create sheer friction fit with the door jamb, locking the entire floor-transition-setting system 100 in place vertically. Against this friction force, the downward pressing pressure-foot 126 have a reaction force sufficient to apply the required curing pressure to the saddle. Removal would require adjusting each foot pressure-foot 126 away from their applied pressure direction. Accordingly, connector-body 102, plurality of extension-bodies 110, plurality of leg-members 118, and plurality of pressure-feet 126 may be in functional and structural combination with each other. Floor-transition-setting system 100 may be structured and arranged to allow a user to provide adjustable pressure to construction-materials 154, such that the user may provide increased pressure to construction-material 154 during assembly.
According to one embodiment, and with reference to FIG. 2, floor-transition-setting system 100 may be configured for toolless coupling. In particular, each connector-body 102 may include a plurality of female-push-button-couplers 104 and aconnector-tubular-body 106, with each connector-tubular-body 106 being in functional and adjustable combination with each female-push-button-coupler 104. Each extension-body 110 may include male-push-button-adjuster-coupler 112 and extension-tubular-body 114, with each extension-tubular-body 114 being in functional combination with each male-push-button-adjuster-couplers 112. Together, the female-push-button-couplers 104 of connector-body(s) 102 may be removably and slidably coupleable to each male-push-button-adjuster-coupler 112 of extension-bodies 110 in a telescopic fashion, so as to toollessly provide an adjustable (here, horizontal) length to floor-transition-setting system 100. It is understood, that other orientations (e.g., vertical, angled, etc.) are contemplated.
Each leg-member 118 may include connector-ring 120 and leg-tubular-body 122, with connector-ring 120 being in functional combination with each leg-tubular-body 122. Each pressure-foot 126 may be configured such that each pressure-foot 126 may be located adjacent to and contacting construction-material 154 (FIG. 1) during use.
Pressure-feet 126 may be removably and adjustably coupleable to an individual leg-tubular-body 122 of plurality of leg-members 118, respectively. Connector-rings 120 may be structured and arranged to encompass each extension-tubular-body 114 of each extension-body 110, to provide a rotatable affixation. Pressure-feet 126 may further include a threaded-connection configured such that the user may adjust a distance between each pressure-foot 126 and construction-material 154 via rotation, and provide the desired-pressure during use.
Referring to FIG. 4B, the pressure-feet 126 may further include a ball-point-pivot 164 configured to allow the user to variably affix floor-transition-setting system 100 at a variety of angles. Also, with reference to FIG. 4C, the pressure-feet 126 may further include a locking-pin-pivot 166 configured to allow the user to variably affix floor-transition-setting system 100 at a variety of angles.
Referring to FIG. 4F, the pressure-feet 126 may further include a quick-release or toggle-switch 168 configured to provide the user with a quick means for adjusting the desired-pressure during use. Additionally, and as shown, the pressure-feet 126 may also include a suction device such as suction-cup 170, which is configured to provide the user with additional resistance, grip, or friction against lateral movement between floor-transition-setting system 100 and construction-material 154 during use. The suction-cup 170 may advantageously replace a pressure-foot 126 on a smooth surface such as ceramic, for example. Similarly, the plurality of pressure-feet 126 may also include a construction based on a rubberized or other non-slip material configured for traction and durability during use.
Referring to FIGS. 4D and 4E, the floor-transition-setting system 100 may also include a tensioner-body 160 structured and arranged between one or more extension-bodie(s) 110 (FIG. 1) and/or at least one pressure-foot 126, tensioner-body 160 configured to provide the user with a wider operational use such that floor-transition-setting system 100 may accommodate wider and/or narrower uses.
Referring to FIG. 4A, the floor-transition-setting system 100 may include a multi-connector 134 that is structured and arranged to provide the user with a variable-length device. The multi-connector 134 may be configured to connect at least one of one or more extension-bodies 110 (FIG. 1), one or more tensioner-bodies 160 (FIG. 4D), and/or one or more extension-bodies 110. For example, the multi-connector 134 may include opposing threaded stud, separated by any convenient distance via structural member, where each stud is configured to engage via the same mechanism as a pressure-foot 126 (FIG. 1), for example. According to one embodiment, the floor-transition-setting system 100 may include multi-connector 134 configured to removably couple two or more systems during use to provide a modular and variable system, similar to the simplified system described above.
Referring to FIG. 4G, the floor-transition-setting system 100 may also be arranged as a c-press-adapter 172. The c-press-adapter may include a first-right-angle-member and a second-right-angle-member. The c-press-adapter 172 may additionally include one or more pressure-feet 126. C-press-adapter 172 may additionally include one or more leg-members. As illustrated, in addition to being modular and adjustable, the c-press-adapter 172 may beneficially be configured asymmetrically.
Floor-transition-setting system 100 may also be adaptable to accommodate the construction and installation of stair treads, by utilizing the riser of the stair, and/or the lower and/or upper stair tread (and/or riser), as well as the stair stringer. Also, floor-transition-setting system 100 may also be useful for the installation and/or repair of cabinetry (including but not limited to installations and/or repairs in bathrooms, kitchens, etc.), as well as providing a functional use for the construction and/or repair of furniture and finishing items.
Floor-transition-setting system 100 may be constructed from a ferrous-metallic material configured for durability during use, may be constructed from a non-ferrous-metallic material configured to be lightweight and provide durability during use, or may beconstructed from a plastic material configured for non-reactive properties during use, according to user requirements and preferences.
Referring to FIG. 2, it should be noted that floor-transition-setting system 100 may be arranged as a kit, for example, with the following parts: at least one connector-body 102, at least one extension-body 110, at least one leg-member 118, a plurality of pressure-feet 126, and at least one set of user instructions 142.
