The present invention relates generally to paint rollers. More particularly this invention relates to bifurcated paint rollers and compatible bifurcated paint trays and stencil tubes.
The bifurcated roller shown in U.S. Pat. No. 5,713,095 includes several drawbacks. For example, the roller is manufactured from two conventional rollers, using two conventional frames. Prior to welding the two conventional frames together, one of the conventional frames is cut below the handle and such handle is thrown away, contributing to the expense of the bifurcated roller.
The bifurcated roller shown in U.S. Pat. No. 5,970,568 includes several drawbacks. This bifurcated roller always presents the roller covers in the same plane and the same orientation. Accordingly, the bifurcated roller is limited in the patterns and surfaces that it is capable of printing. Another drawback is that this bifurcated roller includes an excessively long open space or slot between the rollers. This length wastes the framing rods which form the slot. Further, the size of the slot is not adjustable such that the bifurcated rollers can be moved farther apart of closer together.
The disclosure of the '568 patent also includes a bifurcated paint tray. The drawback of this paint tray is that the wall or barrier that bifurcates the paint tray into two receptacles if permanently attached such that the paint tray is not compatible with non-bifurcated rollers. This permanence requires that a person have at least two paint trays—one that is compatible with a bifurcated roller and one that is compatible with a single roller. Accordingly, there is a need for an improved bifurcated paint tray that is compatible with both types of rollers.
In addition, paint stencils are known wherein a person may paint a pattern on a surface using a roller. In one form a person uses a flat stencil that has a cut-out corresponding to a positive image of the pattern to be printed. This stencil is secured to a surface and then painted over. Usually, such stencils must be moved around or repeatedly placed to form a desired pattern. In another form, rollers are presented with knap that is configured in the pattern to be painted, i.e., devoid of knap in the places of the pattern that are not to be painted. This configuration is limited in that a different roller cover needs to be purchased for each different pattern that a person may want to paint. Accordingly, there is a need for an improved pattern stencil for use with roller covers.
There exists, therefore, a continuing need for further improvements in and to paint rollers, paint trays and stencil patterns. The present invention fulfills these needs and provides further related advantages.
The present invention is directed to an improved paint roller. The inventive paint roller comprises first and second levers connected at a pivot point. Each of the first and second levers has a handle disposed at a first end thereof and a roller arm extending from a second end thereof. The pivot point is disposed at a point between the first and second ends of the levers.
The paint roller includes a pair of roller covers. Each roller cover is rotatably disposed on one of the roller arms of the first and second levers. The roller covers are preferably made from an absorbent material comprising fabric, foam, lamb's wool or mohair. The roller covers on the lever are replaceable with another roller cover.
The roller arms are independently pivotable about longitudinal axes of the respective first and second levers. Each roller arm is independently pivotable through a range of zero degrees to ninety degrees with respect to the first or second lever. A pivot lock is preferably included on the second end of each of the first and second levers. Each of the pivot locks firmly holds the roller arms on either the first or second lever at a particular angle of rotation. The roller arms are also independently extendable along the longitudinal axes of the respective first and second levers with the pivot locks configured to firmly hold the roller arms on either the first or second lever at a particular extension with respect to the first or second lever.
The first and second levers each comprise a first portion corresponding to the first end and a second portion corresponding to the second end. The first and second portions of each lever are functionally connected at the pivot point. The pivot point selectively allows for complementary or opposite movement of the first portion of each lever with respect to the second portion of each lever. A multi-position switch on the pivot point switches the pivot point between complementary or opposite movement. A spring between the first portions of the first and second levers biases the first portions of the first lever away from the second portion of the second lever.
The inventive paint roller may be combined with an inventive paint tray. The inventive paint tray comprises a main paint well having a deep end and a shallow end. The shallow end has an inclined bottom wall that slopes down toward the deep end. A channel is disposed on the back and bottom walls of the deep end and along an adjacent portion of the inclined bottom wall of the shallow end. A divider is configured to be selectively securable to an outside wall of the paint tray. The divider is also configured to be inserted into the channel such that the divider securely engages the channel and divides the deep end and the adjacent portion of the shallow end into two separate receptacles.
In the combination paint roller and paint tray, one of each of the roller arms of the paint roller is dippable into one of the two separate receptacles. The divider has a handle that functions as a spatula tool. The inclined bottom wall has a first pattern in one of the two separate receptacles and a second pattern in the other of the two separate receptacles. A paint tray liner having an integral divider is also configured to be inserted in the main paint well. The paint tray liner with integral divider divides the deep end and the adjacent portion of the shallow end into two separate receptacles.
The present invention is also directed to a stencil tube for use with paint rollers. The stencil tube comprises an elongated hollow tube configured for sliding engagement with a roller cover. An opening in a wall of the elongated hollow tube permits a potion of the roller cover to extend through the opening. The elongated hollow tube remaining around the opening forms a negative image of a pattern to be painted on a surface by the roller cover.
The elongated hollow tube is preferably made from a non-absorbent material comprising plastic or laminated paper. The elongated hollow tube is removable from the roller cover and replaceable with another hollow tube having a different pattern to the opening. The pattern preferably comprises letters, numbers, shapes, or a combination thereof.
Other features and advantages of the present invention will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
The accompanying drawings illustrate the invention. In such drawings:
As shown in the exemplary drawings, an inventive dual-roller paint roller referred to generally in
In a preferred embodiment, the pivot point 36 functions to have the first and second levers 32, 34 function together as would the levers of a pair of pliers. As the handles 38 are moved apart so too are the roller arms 40. Conversely, as the handles 38 are moved closer together so too are the roller arms 40. As with pliers, the farther the pivot point 36 is from the handles 38, the greater the leverage that is exerted on the second ends 32b, 34b and/or the roller arms 40.
In particularly preferred embodiment as shown in
The roller covers 42 a configured to be disposed onto the ends of the roller arms 40 as is known by those skilled in the art. The roller covers 42 may comprise “large”—type rollers configured to slide over a hollow frame structure 47 rotatably disposed on the roller arms 40, as shown in
The roller arms 40 are preferably fixed in their position with respect to the second ends 32b, 34b of the levers 32, 34, i.e., not extendable or retractable. However in an alternate embodiment, the roller arms 40 may be extendable and retractable along the longitudinal axis of the levers 32, 34. The extension/retraction of the roller arms 40 may be selectively fixed by the pivot locks 48, in a similar manner that the pivot locks 48 fix the angle of rotation.
The rotatable nature of the roller arms 40 allows for the paint roller 30 to be used to more conveniently paint certain types of surfaces. With the roller arms 40 in a perpendicular orientation (
In another configuration, the roller arms 40 may be positioned parallel or adjacent to one another (
In conjunction with the paint roller 30 described herein, the inventor has also invented a stencil tube 62 to be used with a roller cover 42, as generally illustrated in
The opening 66 and knap 68 of the roller cover 42 are preferably configured such that a sufficient portion of the knap 68 protrudes through the opening 66 to absorb and apply paint when in use. A person using the stencil tube 62 may use tape or other similar adhesive to “pull” the knap 68 through the opening 66. Obviously, roller covers 42 with a longer knap 66, i.e., mohair or similar, will function better than a roller cover 42 with a shorter knap 66, i.e., foam. The stencil tube 62 may comprise a pre-formed tube (
The stencil tube 62 may be used in conjunction with the inventive paint roller 30 or any prior art paint roller, such as those having a single roller cover.
In combination with the inventive paint roller 30, the inventor has also invented a paint tray 72 that includes two separate paint receptacles 74a, 74b. The receptacles 74a, 74b are configured to simultaneously receive the roller covers 42 of the inventive paint roller 30, as shown in
A divider 80 is disposed between the first and second receptacles 74a, 74b. The divider may be permanently affixed within the paint tray 72. In a particularly preferred embodiment, the divider 80 is removably disposed or “snapped” into a channel 82 that runs down the approximate center of the paint tray 72. The channel 82 runs along the back wall 76a, the bottom wall 76b, and at least a portion of the inclined bottom wall 78b. The divider 80 and channel 82 are configured such that the divider 80 is securely held in the channel 82 such that the first and second receptacles 74a, 74b are completely separated when the divider 80 is in position. Completely separating the first and second receptacles 74a, 74b allows for different colors or types of paint to be used in each receptacle 74a, 74b while maintaining their purity, i.e., they are not mixed. When the divider 80 is removed from the channel 82, it may be stored in a holder 84 positioned on the side of the paint tray 72. The divider 80 may also include a handle 80a and a spatula tool 80b, which can be used as a person of ordinary skill in the art would use a spatula tool.
The receptacles 74a, 74b preferably include patterns 86a, 86b disposed on the inclined bottom wall 78b. The patterns 86a, 86b may be same or may be different as illustrated. Different patterns 86a, 86b allow for different texturing of the paint on the roller covers 42. A person of ordinary skill in the art will appreciate the differences that result from the different texturing.
The inventive paint tray 72 may also comprise or come in the form of a paint tray liner 88 including two separate receptacles 74a, 74b, as illustrated in
Although several embodiments have been described in detail for purposes of illustration, various modifications may be made without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
