This invention relates generally to paint rollers, and more particularly to paint rollers arranged to support the paint roller frame assembly for rotation on a supporting base of the paint roller arranged for mounting connection onto the end of an extension pole member.
Paint rollers have long been used for painting large, flat, expansive areas such as walls, floors and ceilings and when held in the hand of an operator, provide the user with great versatility in such painting operations. Specifically, rollers may be moved over the surface being painted in straight, vertical and horizontal directions of travel as well as arcuate directions of travel movement, without need of lifting the roller from the surface being painted, by normal and natural articulation of the wrist and arm, as is well known.
However, as is also well known, paint rollers are frequently used on the ends of extension pole members in order to provide greater reach of the painting operation without need of the operator standing on ladders or step stools, etc. However, as is well understood in the art, when paint rollers are mounted on the end of longitudinally elongated extension pole members, the aforementioned versatility of the painting operation offered by the articulation of the wrist and arm of the operator is entirely lost, and painting operations are typically then restricted to vertically extending directions of movement between which the roller is typically lifted off of the surface being painted for lateral movement of the assembly and placement back onto the surface for another vertical painting operation. Since the paint roller apparatus is mounted at the end of a long extension pole member, any arcuate travel of the roller requires wide angling of the long extension pole member or movement of the operator about the floor surface to accomplish angling of the roller for travel during painting. As will be appreciated by those skilled in the painting industries, when a roller is moved upwardly along a wall to a point near the juncture of the wall with the ceiling, upward travel is stopped and the roller lifted and moved to the left or right in order to paint another vertical stretch. This stopping and lifting the roller and replacing it on the surface being painted typically leaves a pooling of paint on the surface and requires follow-up detail painting with a brush to smooth out the pooling and to finish painting the wall surface to its juncture with the ceiling, as is understood.
U.S. Pat. No. 5,903,952 discloses an indexable paint roller frame arrangement that is supported rotatably on a roller handle member for indexing of the roller cage and cover of the roller to several different positions to permit the paint roller to reach difficult faces and angles of a painting surface identified as such things as railings, cabinets, pipes, trim and the like. In this regard, the indexable paint roller arrangement provides for indexed rotating movement of the roller cover on a plane that is spaced perpendicularly from and extends parallel to the longitudinal axis of the handle of the paint roller. This arrangement is generally similar, in terms identifiable to the layman, to the overall appearance and relationship of a helicopter main rotor rotating above the body of the helicopter.
Given the earlier discussed limitations imposed on paint rollers when mounted on the end of longitudinally elongated extension pole members, it is evident that a benefit would be derived by the provision of a paint roller apparatus which is arranged to generally simulate the general painting orientations achieved by the articulations of the wrist and arm when the paint roller is supported on the extension pole during painting operations.
In its basic concept, this invention provides a swiveling paint roller apparatus arranged for mounting on the end of a longitudinally extending extension pole for rotation of the roller cage-mounting roller frame assembly about an axis of rotation that extends at a predetermined, selected acute included angle of between 20 degrees to 80 degrees relative to the longitudinal axis line of extension of the base mount member supporting the roller frame, for swiveling movement of the roller cage on a plane disposed angularly forwardly of and intercepted by the longitudinal axis of extension of the supporting base mount member and an extension pole mounting the base mount member, in order to permit roller painting operations with an extension pole that substantially simulates paint roller operation afforded by hand and arm articulation movements when paint rollers are held in the hand of an operator.
It is by virtue of the foregoing basic concept that the principal object of this invention is achieved; namely, the provision of a swivel paint roller for use on extension poles and arranged to permit continuous rolling contact of the roller cover with a surface being painted in different directions of linear and arcuate travel of the roller over the surface, whereby to overcome the limitations and disadvantages of conventional extension pole-mounted paint rollers and their capabilities in painting operations provided heretofore.
Another object of this invention is the provision of a swiveling paint roller apparatus of the class described in which the rotational swiveling of the roller frame may selectively be substantially unrestricted or adjustably tensioned, whereby to selectively control the force required to effect swiveling of the paint roller on the end of an extension pole during painting operations.
Another object of this invention is the provision of a swivel paint roller apparatus of the class described in which the swiveling roller frame may if desired be releasably locked in selected positions of rotational orientation and against swiveling movement on its supporting base for substantially fixed, conventional use of the paint roller apparatus.
Another object of this invention is the provision of a swivel paint roller apparatus of the class described which provides the painter with more flexibility and mobility in roller painting operations using extension poles, including the ability to continuously roll in opposite directions involving compound angles and curves by simple twisting of the extension pole held in hand, giving the painter a broader range of painting from a single position or ladder placement, and further allowing the operator to “steer” around windows, doors and corners not normally possible with an extension pole-mounted conventional roller.
A further object and advantage of this invention is the provision of a swivel paint roller apparatus of the class described which is of simplified construction for economical manufacture and reliability of operation.
The foregoing and other objects and advantages of the present invention will appear from the following detailed description, taken in connection with the accompanying drawings of a preferred embodiment.

The earlier-mentioned and other objects and advantages of the swivel paint roller apparatus of this invention are accomplished by the provision of a paint roller assembly 10 as illustrated in
Many different types and forms of tool mount members have been provided heretofore for securing various painting and other tools releasably onto the mounting end of extension pole members. In this regard, the base mounting member 12 may be arranged as desired for mounting interconnection with any type of such extension pole tool mount. For purposes of illustration in this regard, and as shown best in
As also seen in
Critical to the present invention, as shown in the drawings and illustrated specifically in
This angular axis of rotation arrangement provides for rotation of the roller frame 30, roller cage 32 and roller cover 34 combination about the axis of inner frame rod end 30′ rotating within the bore 28, 28′ for swiveling, rotating movement of the roller frame, cage and cover assembly on a plane that is disposed forwardly of the front end 14 of the base mount member 12 and intersected angularly by an imaginary line 24″ (
As shown best in
In the particular embodiment illustrated, an end guide member 42 includes an internal, longitudinally extending bore 44 therethrough arranged for free reception of the threaded rod end portion 30″ and overlying tension spring 38 as shown in
An internally threaded end screw cap member 48 is provided to threadably engage the threaded end portion 30″ of the inner end 30′ of the frame rod member 30 as seen clearly in
As will also be readily understood in
As shown, the front end 14 may, if desired be provided with one or more annularly spaced frame rod seats 54 arranged to provide selected, positive stop points of rotation of the roller frame rod 30 relative to the base mount 12. Such frame rod seats may be provided in the form of shallow depressions as shown, or in any other suitable, alternative configuration as may be desired including shallow grooves, notches, surface knurling, or other forms of stops. Clearly with such rod seats provided and with the frictional abutment tension of the rod 30b against the front end 14 adjusted by end cap screw 48 adjustment of the spring tension as previously explained, and with the frame rod length 30b engaged by a rod seat 54, the rotational orientation of the roller frame and cover relative to the base mount body 12 will be maintained until and unless the relative rotational force therebetween exceeds the selected spring tension force, as is readily apparent to those skilled in the art.
From the foregoing therefore it is apparent that the purpose and operation of this invention is to provide an operator with more flexibility and mobility when a using a paint roller on the end of an extension pole. Typically, when an operator uses a conventional paint roller mounted on the end of an extension pole, he must paint in linear strokes, and loses the ability to paint compound angles and to turn and to manipulate the direction of the roller as can be done by virtue of wrist, elbow and shoulder functions when the paint roller is being held directly in the operators hand.
The swiveling paint roller apparatus thus described and illustrated herein thus effectively simulates the wrist and arm articulation movements, etc. of a hand-held paint roller to re-orient the roller and direction of roller movement by providing a swivel paint roller on the end of an extension pole that can change angles and directions of movement by simply twisting or rotating the extension pole member P held in the operators hands as the painting operation is being done, as is clearly reflected in the illustration of
As previously mentioned, the swivel tension is adjustable as desired by adjustment cap screw 48 in order to adjust a set degree of pressure against the painting surface that is required to change the angle or rotational positioning of the roller by twisting movement of the extension pole member. This swiveling or angle changing effect, by twisting the extension pole, is possible because of the difference in the plane in which the roller frame is rotating relative to the longitudinal axis on which the extension pole is being rotatably twisted. That difference of angle determines the degree of angle change.
In this regard, the lesser the angle, for example the 20 degree angle represented by center line 36′, the less and slower the angular change of the roller cage and roller cover against the work surface. The greater the angle difference, for example the 80 degree angle indicated by centerline 36″, the greater and more rapid the angle change. As indicated previously the optimum angle difference is approximately 30 degrees, but angular positioning of the frame rod body mount 26 of between 20 degrees to not more than 80 degrees is considered satisfactory.
a illustrate that the previously described structural arrangement of
As illustrated the notches are arranged with selected, declining depth wherein the depth of notch 56 is arranged to permit longitudinal movement of the frame rod sufficient for the frame rod section 30b to fully and freely move out of a seat 54 with minimal tension supplied by the preset tension of the tension spring 38. Notch 60 is arranged with a shallow depth which, as shown in
An intermediate notch 58 may be provided with an intermediate depth selected for abutment with tab 62 allowing for sufficient movement of the rod within the rod mount body to permit movement of the rod length portion 30b to move close enough to separation from the rod seat 54 with a slightly increased amount of force required to overcome the preadjusted spring tension set by the adjustment end cap 48. To facilitate identification of the rotational orientation of the end guide member and the aforementioned positioning of the respective notches 56, 58, 60 relative to the tab 62, a finger tab 64, seen best in
The operation and operational features of the swivel paint roller apparatus of this invention are well understood in viewing
From the foregoing it will be apparent to those skilled in the art that the invention thus described provides a swiveling paint roller apparatus that is arranged to provide a paint roller for use on the end of an elongated extension pole yet arranged to substantially duplicate the movements thereon that are otherwise only achievable by a paint roller being held directly in the hand of its operator. From the foregoing it will also be readily apparent to those skilled in the art that various changes, other than those already described may be made in the size, shape, type, number and arrangement of parts described hereinbefore without departing from the spirit of this invention and the scope of the appended claims. As an example, the longitudinally elongated base mount member may be configured if desired for convenient grasping in the hand of a user, for normal hand-held operation when the assembly is locked in the position of
