FIELD OF THE INVENTION
The present invention relates to adapters to existing tools designed to improve effectiveness, efficiency and user experience of existing wall finishing tools.
BACKGROUND OF THE INVENTION
Caulking is a process of applying a compound for ascetic or moisture sealant purposes. Caulking is done by extruding a bead of caulking compound from a tube or canister into a seam or joint. The procedure is then followed by leveling the spreading or brushing or scraping away of excess compound.
Presently, the caulking process is a three-step procedure. The first step is preparation of surfaces, which primarily is focused on placing protective masking or painter's tape on areas adjacent to the seam. After the taping is completed, actual caulking commences. After caulking, one uses a scraping tool, usually a spade trowel, to compact the compound into the seam and simultaneously scrape away excess material. There is also the fourth step of removing the protective tape and performance of other cleanup tasks.
The steps of taping, caulking and scraping are time consuming and labor intensive. Each process requires that a laborer performing the task, perform work on the same area at least three times, Furthermore, since placing of the tape on the seam is a separate process, a laborer tends to use more tape than necessary to achieve the desired result. Therefore, combining the first three steps of taping, caulking and scraping into one step greatly improves efficiency and reduces labor requirements and the tedium of the task.
SUMMARY OF THE INVENTION
It is an object of the present invention to reduce time spent on caulking projects.
It is another object of the disclosed apparatus to combine the steps of taping, caulking and scraping into one step.
It is another object of the disclosed invention to combine tools required in initiating and completing the caulking operation into a single apparatus.
The present disclosure describes an adapter apparatus that is intended to be used in combination with caulking cradle containing a caulking cannister. It is understood that the disclosed adapter can be used with a device having a similar use and purpose as a caulking frame.
The application discloses a base wall having a first end and a second end. A first attachment means, and a second attachment means are attached to the base wall. The first attachment means secured to the base wall near the first end. and the second attachment means secured at the second end of the base wall. The first and said second attachment means are intended to secure the base wall to a canister cradle of a caulking gun.
Further disclosed is an angle bracket the angle bracket attaching to the base wall at the first end. The angle bracket having a first wall. The first wall is attached to the base wall in a perpendicular orientation or direction with respect to the base wall. The overall angle bracket comprising of a first wall having a second wall and a third wall. The second and third walls extending downwardly from the first wall, in a parallel, spaced apart relation to each other.
In one embodiment of the disclosed apparatus, the second wall and a third wall contain openings that are co-axial. The openings supporting a first pivot mounted within the first openings. The first pivot rotatingly supporting a first roller.
The base wall further discloses a rear angle bracket. The rear angle bracket mounting along the length of the base wall. The rear angle bracket extending downward from the base wall and comprising a rear pivot that is at a right angle to the axis of the base wall. The orientation of the rear pivot is also parallel with the first pivot. The rear pivot rotatingly supporint a first back roller. When the first roller and the first back roller are lined up one behind the other, such as when looking directly at the front of the disclosed adapter, the first roller and the first rear roller are linearly one behind the other.
The back roller is intended to support a reel of tape. A user of the apparatus would then take a free end of this tape and extend it towards the first roller. The strip of tape so extended is then passed between the first roller and the work surface.
It is preferred that the disclosed adapter contain a supplemental pivot mounting between second and third walls behind the first pivot. The supplemental pivot is in a parallel and spaced apart configuration with the first pivot. The supplemental pivot may contain one wide or several narrower rollers. The purpose of the supplemental roller(s) is to guide the section of the tape being unraveled from the first rear roller over the supplemental roller, such that the free end of the unraveled tape will pass between the first roller and the work surface.
In a further embodiment, it is preferred that the disclosed adapter contain a second roller and a second rear roller. The second roller is mounted on the first pivot, adjacently, but in spaced apart configuration with the first roller. The second rear pivot is mounted on the rear pivot of the rear bracket in a parallel configuration with the first rear roller. The second roller and the second rear roller are positioned in the same linear orientation with one another.
The second roller is intended to support a reel of tape in addition to or instead of the tape being supported on the first rear roller. A free end of the tape on this tape roller is unraveled and passed over the one or more supplemental roller and then beneath the second roller, such that the tape is pressed by the second roller against the work surface.
In one embodiment of the disclosed adapter the space between the first and second roller is regulated using at least one third roller, which is mounted between the first and second rollers. Additional third rollers, or alternatively, fewer third rollers may be used to regulate the space between the first and second rollers. It is preferred that the third roller is of greater diameter than the first and second roller. The third roller is then placed into the groove being worked on by the disclosed device, and functions as a guide to ensure that the adapter remains directly over the seam being caulked as a user drags the disclosed adapter and the calking gun over the work surface.
Further disclosed with the present adapter and across all embodiments disclosed below is a scraping tool that is used to direct the caulking compound into the same and, to also clear away access caulking compound. The scraping tool is shown to be in the form of a spade, but other scraping tool variations may be easily adopted for use with the disclosed apparatus. The scraping tool is mounted to the angle bracket using forked support arms that are inserted onto slots on parallel supports. The parallel supports are mounted on the top surface of the first wall of the angle bracket.
In some embodiments the height and degree of extension of the scraping tool with respect to the front, of the adapter can be controlled using pinned slots that exist along the height of the parallel upright supports, to control elevation, and using pinned slots of the forked support arms, to control extension. The scraping tool is intended to be situated just ahead of an extruding nozzle, such that the compound being extruded by the nozzle, is then immediately leveled and trimmed by the scraping tool.
In another embodiment the first pivot does not directly rotatingly mount either the, first or the second rollers mounted thereon. Instead, the first and second rollers are mounted onto the first or second roller cradles, respectively. The first roller cradle is comprised of a first adjustment wheel is threadingly mounted onto the first pivot. A non-rotating sleeve is attached obliquely to the first adjustment wheel, the sleeve being in a parallel spaced apart configuration with the first pivot. The first roller is then rotatingly mounted and removable mounted onto the sleeve.
Similarly, the second, roller cradle is formed using a second adjustment wheel which is thredenegly mounted on the first pivot in an adjacent, spaced apart orientation to the first adjustment wheel. A sleeve extending from the second adjustment wheel in a direction opposite from the sleeve extending from the first adjustment wheel. The sleeve attaching to the second adjustment wheel being in a parallel, spaced apart and non-rotating relation to the first pivot. A second roller then rotatingly mounted onto the sleeve of the second cradle.
The space between first and second rollers in the first alternative embodiment being controlled by rotating the first and second adjustment wheels, thus spreading apart or drawing closer the gap between the first and second roller cradles along the length of the first pivot.
It is preferred that the tread of the first and second adjustment wheels extends beyond the surface of the first or second roller so as to dip into the seam being caulked and prevent the adapter slipping off of the seam. It is another preference of this embodiment to have a terminal wheel at the free end of the sleeves issuing obliquely from the first and second adjustment wheels. The terminal wheel is attached to the sleeve and thus rotates together with the shaft as the adjustment wheel to which the shaft is attached is rotated to change the position of the first or second cradle along the length of the first pivot
Plates protruding from between the first and second roller and between the first and second adjustment wheel, respectively, may extend into the seam being worked on, so as to function as guide measure to keep the disclosed adapter centered above the seam.
In the first two embodiments disclosed above, the first pivot is mounted through circular first openings by having the first openings being threaded, or by using lug or wing nuts to secure a section of the first pivot protruding through the first openings.
In another embodiment the first pivot is replaced by an assembled pivot dedicated to an individual first or second roller. In this embodiment, the first opening is shaped as a socket, such as a square or hexagonal socket. A first fastener having a head portion fitting within the socket of the first opening. Head being substantially flat or cup like. A threaded portion of the first fastener then extending into the angled bracket and threadengly jointed with a first horizontal sleeve. The first horizontal sleeve is terminated by a first horizontal flange.
Similarly, a second roller is rotatingly mounted over a second horizontal sleeve. The second horizontal sleeve is held in place by a second fastener, where the head of the second fastener is locked in the socket first opening of the third wall. The second vertical flange terminating the second horizontal sleeve. The central gap between the first and second rollers is then maintained by first and second vertical flanges Thus rotating the flange causes the horizontal sleeve to travel along the length the first or second hosteller, causing the distance between the first or second rollers to grow or decrease.
Two additional embodiments are possible. In one embodiment the upright supports and the forwardly extending scraping tool is not disclosed. Disclosed are only the first or second rollers, together with first or second rear rollers, with a supplemental roller being closely associated behind the first or second rollers.
In another embodiment, two parallel upright supports are used to mount support arms of a scraping tool. The support arms come together at a point just ahead of a nozzle of a cannister being retained with the caulking gun. Extending beyond this point is the scraping tool. In this embodiment, taping is either not needed or is performed as a separate step.
