Patent Application
20200256067
The present invention relates generally to repairing surfaces, and more particularly, relating to a surface repair tool for applying a repair compound and sanding the repair compound.
Holes, cracks, dents or other imperfections in walls, ceilings, and other surfaces are often repaired by a repair compound, such as spackle (spackling) or putty. Spackling is applied to the surface of a wall to fill a hole in the wall, for example, using a putty knife. In practice, the putty knife is dipped into a container of spackling to coat the knife and then the spackling is spread across the surface. After the spackling dries and hardens, it is sanded smooth by sandpaper or a sanding block, for example. This process has many drawbacks, such as needing multiple tools, and it can be messy by having to dip the putty knife into the container of spackling, which often results in wasted spackling and contaminated spackling.
Recognizing these problems, several compound dispensing and applying devices have been devised to repair surfaces. While these prior devices fulfil their respective objectives and requirements, there remains a need for an improved tool for repairing surfaces with a repair compound.
In view of the foregoing described and other inherent disadvantages in known surface repair devices, embodiments of the present invention provide a new surface repair tool for applying repair compound to a surface and sanding dried repair compound.
An object of embodiments of the present invention is to provide a single tool that can be used for both applying a repair compound to a surface and sanding the repair compound after it dries.
Another object of embodiment of the present invention is to provide a surface repair tool that holds a container of repair compound that is dispensed through an applicator blade and onto an application surface of the blade for spreading onto a surface to be repaired.
Another object of embodiments of the present invention is to provide a surface repair tool prevents repair compound waste and eliminates repair compound contamination.
In general, in one aspect, a surface repair tool includes a handle having opposite first and second ends, a length extending between the first and second ends, and first and second opposite sides. The handle has an internal receptacle for removably receiving a container therein and a passage extending from an end wall of the receptacle through an end wall of the handle at the first end of the handle. A blade is attached to and extends outwardly from the first end of the handle. The blade has a blade edge, an application surface, and a flow passage terminating at an orifice formed through the application surface. A collapsible container is removably positioned in the receptacle and has an opening through which a repair compound in the container can flow. The opening of the collapsible container is fluidically connected to the flow passage of the blade. A slide captively is held, for back-and-forth movement, in a longitudinal slot formed through the first side of the handle. The slide having a thumb button located on an exterior side of the handle and a curved bow located on an interior side of the handle within the receptacle. The curved bow pressing against the collapsible container when the slide is moved in a direction toward the first end to compress the container and dispense repair compound through the orifice and onto the application surface. And a sanding pad is attached to the second end of the handle and an abrasive is located on the sanding pad.

Identical reference numerals do not necessarily indicate an identical structure. Rather, the same reference numeral may be used to indicate a similar feature of a feature with similar functionality. In the drawings:
With reference first to
Handle 12 defines an interior receptacle 22 that is accessible through an opening 24 that is formed through side 20 of the handle. Receptacle 22 is configured to removably receive therein a container 26 containing a repair compound. Container 26 has a container body 28 that is made of a collapsible material, such as, for example foil, and neck 30 with an opening 32 through which repair compound can flow when the container body is compressed. Opening 32 may be sealed by a puncturable membrane. End wall 34 of the receptacle 22 defines an aperture 36 that is configured to removably receive neck 30 of the container 26 when the container is disposed within the receptacle. A cover 27 is removably attachable to handle 12 to close the opening 24 and hold the container 26 in the receptacle.
Tool 10 further includes an applicator blade 38 for applying and spreading repair compound on a surface. In the illustrated embodiment, blade 38 is removably attached to the handle 12 at end 14 and is configured to be fluidically connected to container 26 for dispensing and applying repair compound from the container onto a surface.
More particularly, blade 38 has a blade edge 40, an application surface 42, a neck 44, a flow passage 46 extending through the neck and terminating at an orifice 48 formed through the application surface, and a back edge 50 that is opposite of the blade edge. The neck 44 of the blade extends outwardly beyond the back edge 50 and terminates at a free end with an opening into the flow passage. Blade 38 is removably attached to handle 12 by inserting the neck 44 into passage 52, which is formed through end wall 15 of the handle and connects with aperture 36. As the blade is inserted into passage 52, the back edge 50 engages with a slot 54 formed across end wall 15 of the handle. When the back edge 50 of the blade 38 is fully seated in slot 54, a friction lock prevents the blade from being disconnected from the handle 12. The blade 38 can be disconnected from the handle by pulling on the blade with enough force to overcome the locking force. Side edges of the blade may have finger recesses 56 that allow one to grip the blade and pull it free of the handle.
With the blade 38 fully attached to the handle 12 the free end of the neck 44 extends through opening 32 of container 26, thereby fluidically connecting the container with the flow passage 46. In this manner, repair compound can flow from the container 26, through the flow passage 46, and then dispensed through orifice 48 onto the application surface 42 of the blade to be spread on a surface needing repair. If opening 32 of container 26 is sealed by a pierceable membrane, the free end of neck 44 may be configured to pierce such a membrane when inserted through the opening.
As discussed above, container body 28 is made of a collapsible material, such as foil, so the repair compound can be squeezed from container 26. To this end, tool 10 includes an ejector mechanism for compressing or squeezing the container body 28 to dispense the repair compound from the container. In the illustrated embodiment, the ejector mechanism includes a slide 58 that is slidably engaged with the handle 12 to be moved longitudinally back-and-forth along a length of the handle. Particularly, the slide 58 is captively held, for back-and-forth movement, in a longitudinal slot 60 formed through side 18 of the handle 12. The slide 58 includes a thumb button 62 that is located on the exterior side of the handle 12 and which is engageable by user's thumb to move the slide along the slot 60 when the user is holding the handle. The slide 58 also includes a curved bow 64 that is located on the interior side of the handle within the receptacle 22. The bow 64 is configured to press against the side of the container body 28 and compress or squeeze the container body against the receptacle wall as the slide is moved in a direction toward end 14 of the handle 12.
While not shown, slide 58 may be retained at incremental forward positions by a retaining mechanism, such as, for example a linear ratchet and pawl to prevent backward movement once the slide is advanced in a forward direction. In an embodiment, the slide may be fitted with a pawl that is engageable with a ratchet located along the length of the slot. The pawl can be disengaged from the ratchet to move the slide backward.
Tool 10 further includes a sanding block 66. As illustratively shown, the sanding block 66 may comprise a foam body having a working surface 68 that has an abrasive dispose therealong and an opposite mounting surface 70. The sanding block 66 is removably attachable to sanding pad 72 which is connected to end 16 of the handle 12 by neck 74. The sanding block 66 may be removably attached to sanding pad 72 by a touch fastener, such as, for example, a hook-and-loop fastener wherein the loop fastener material may be disposed on one of the mounting surfaces 70 or the sanding pad 72 and the hook material disposed on the opposite.
Alternatively, while not shown, the sanding block 66 could be replaced by sandpaper that is attachable to the sanding pad 72. Further, in other embodiments, it is contemplated the sanding pad 72 could be shaped to sand interior corners or shaped to sand exterior corners. In such an embodiment, the sand block 66 would be shaped to correspond to the shape of the sanding pad. In other embodiments, it is contemplated to provide tool 10 such that the sanding pad 72 may be detached from the handle and be provided with different shaped sanding pads and corresponding sanding blocks. In such an embodiment, the tool 10 could be configured such that the sanding pad 72 is removably attached to the neck 74 or the neck with the sanding pad is removably attached to the handle.
Several embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
