Abstract
A support bracket is releasably attachable to a telescopically extendable and collapsible pole assembly at a side of one pole section of the assembly so that a support arm projects laterally outward from the pole section at an intermediate position of the pole assembly spaced from a ceiling-engaging end of the pole assembly. The support arm defines or carries a support surface on which a length of crown moulding can be seated. The pole assembly is extended to reach between the floor and ceiling at a short distance laterally outward from the wall so as to stand in a self-supporting upright position frictionally engaging the floor and ceiling with the support arm reaching toward the wall so that the crown moulding seated on the support surface is carried in a substantially installation-ready position at the wall/ceiling joint.
Description
SUPPORT APPARATUS AND EXTENDABLE POLE ACCESSORY FOR
SUPPORTING CROWN MOULDING OR OTHER ELONGATED WORKPIECES
ON A WALL SURFACE
FIELD OF THE INVENTION
The present invention relates generally to an apparatus for supporting crown moulding or another similar workpiece against a wall surface during installation, and more particularly to a support bracket mountable to a side of an extendable pole assembly for use in such context.
BACKGROUND OF THE INVENTION
It has been previously proposed in the prior art to address the difficulty of installing crown moulding at the corner joint between an upstanding wall and overlying ceiling without an assistant by using an elongated pole-like tool carrying one or more resilient pads thereon to brace the crown moulding up into this corner.
For example, U.S. Patent No. 7,603,817 and U.S. Patent Application Publication No. 2011/0303815 both teach use of a pole on which a spring-loaded end assembly is mounted, whereby the overall length of the tool can be compressed to a small degree by forcing the top-end assembly up against the ceiling near the corner between the ceiling and the wall so as to wedge the tool into a frictionally-maintained position angling upwardly toward the corner from a greater distance outward from the wall. This position is maintained by a floor engaging member frictionally gripping the floor at the lower end of the sloped pole and a ceiling engaging pad frictionally gripping the ceiling. A second pad is carried on a same pivotally mounted body of the top-end assembly as the ceiling pad for placement of this second pad against the wall. These pads are carried on support arms that join the pads to the pivotal body, whereby the support arms cooperate with the wall and ceiling to define four sides of a "box area" or "encapsulating space" in which the crown moulding is received, and thus supported in a position at or closely adjacent the corner defined between the wall and ceiling.
The sloped angle wedge-type fitting of the apparatus between the floor and ceiling may result in some concern over the possibility of the floor-engaged end slipping out of place and allowing the crown moulding to fall, potentially causing damage or injury.
The prior art also includes tools for supporting crown moulding from the ground to avoid the risk of potential fall from a ladder, which is often required in order to reach high enough to manually support a piece of crown moulding at the desired point of installation.
For example, U.S. Patent Application Publication No. 2007/0119062 teaches a crown moulding tool in which two pads are again provided at a top end of a pole-shaped handle, but the pads are both directly coupled to a pivot body attached the top end of the pole, and the crown moulding is held in place with these pads. As best understood, the tool appears to be manually held in place during use, and thus doesn't provide a self-supporting solution freeing up both hands of a single user to allow moulding installation without an assistant.
Elongated tools for supporting workpieces or objects other than crown moulding have also been proposed, as outlined below, but don't appear to be suitable for bracing crown moulding during installation of same due to the shape and corner-joint location of such moulding.
U.S. Patent No. US8376341 teaches a tool with a base member configured to engage a ladder or scaffolding rung at the bottom end of a length adjustable rod, which also carries a lateral brace projecting perpendicularly from the rod at an intermediate location to attach to a point of greater height on the ladder or scaffold. A top end of the adjustable rod carries a support member for holding up the object or workpiece in question.
PCT Publication No. WO 96/01353 teaches an extendable prop device for holding up construction materials. A central tube telescopically receives two smaller end-tubes in its opposing ends. One end tube is manually adjustable in its extension from the central tube, and lockable relative thereto by a cam mechanism, and the other end tube is spring biased to a position of maximum extension.
End caps of frictional material are mounted on the end tubes may engaging a floor at one end and the piece of construction material at the other. Different heads may be substituted for one cap depending on the type of material to be supported. The device is described as useful for temporarily supporting ceiling tiles and cabinets, U.S. Patent No. D592822 discloses a lifter that is commercially available from the A. Richard Tools Company, but is designed for lifting wall-finishing panel-shaped materials such as drywall, and not crown-moulding or other corner-finishing materials.

DETAILED DESCRIPTION
Figure 1 shows a support bracket 10 of one embodiment the present invention designed as an accessory for a commercially available, telescopically extendable and collapsible pole assembly marked as the Quick Support R0dTM by Task Tools ¨ Div. of Caplan Industries Inc. of Delta, British Columbia, Canada. The support bracket is used in order to convert the pole assembly into a suitable tool for supporting crown moulding or other elongated material at an elevated location at the corner joint between an upright wall and intersecting ceiling.
The support bracket features an elongated base member 12 of linearly extending vertical orientation, and a support arm 14 of linearly extending horizontal orientation fixed to and projecting perpendicularly from the base member 12 at the top end thereof. In the illustrated embodiment, each of these members is formed by a respective length of angle iron, but members of other shape and material may alternatively be employed to achieve similar result, as will be appreciated from the following further description of the structure and function of the support bracket. The base and support arm may be mitered at the corner joint between them, as shown Figure 1. A diagonal brace 15 spans obliquely between the base and support arm 12, 14 from near a distal end of the support arm that lies opposite the base to a distance partially down the base 12 from the joint of the base with the support arm.
The brace may be formed of a thin metal bar or strip of metal plate placed flush against coplanar faces of the angle iron base and support arm members 12, 14.
In other embodiments, sufficient joint strength between the base and support arm may omit the need for a reinforcing brace between the two.
A third piece of angle iron defines a right angle support rail 16 fixed to the support arm 14 at the distal end thereof in a horizontally extending position lying perpendicularly cross-wise to the support arm 14. A horizontal leg 18 of the angle iron support rail 16 has its top surface 18a flush with a horizontal top surface 19a of the support arm 14 in place of a cut-away end portion of the horizontal leg 19 of the support arm 14 from which the vertical leg of the support arm's angle-iron structure depends. The topside 18a of the support rail's horizontal leg 18 defines a support surface atop which the crown moulding is seated during use of the support bracket in the manner described herein further below. The vertical leg 20 of the support rail 16 depends downward from the horizontal leg 18 thereof at the edge of the horizontal leg lying furthest from the base member 12 just beyond the distal end of the support arm 14. The surface 20a of this vertical leg facing laterally away from the base member forms a wall engagement element for placement against the wall on which the crown moulding is to be placed at a height spaced downward from the ceiling.
Turning back to the base member 12 of the support bracket 10, a pair of slot-shaped openings 22 are respectively cut through the leg 24 of the angle iron base 12 that lies in a vertical plane perpendicular to the length of the horizontal support rail 16 and to which the diagonal brace 15 is flush mounted. Each of the two slots 22 has an elongated direction lying parallel to the vertical length of the base member 12, and is located nearer a respective one of the top and bottom ends of the base member. A respective strip of flexible material 26 having two opposing free ends and passes through each slot 22, and an intermediate portion of the strip is fastened to the base through the other leg 28 of the base's angle iron shape, which lies in a vertical plane perpendicular to the slotted leg 24 of the base so as to face away from the support arm and rail 14, 16. In the illustrated embodiment, the strip of material is fastened by a rivet 30 that is engaged through the leg 28 of the base, and onward through the flexible strip 26, where it engages a flat washer 32. The flexible strip is thus sandwiched in place between the washer and the leg of the base.
An area of hook material 26a is fixed to one face of the flexible strip to extend at least a partial length of the strip from one free end thereof, and a strip of 5 mating loop material 26b is fixed to the other face of the flexible strip to extend at least a partial length of the strip from the other free end thereof.
Accordingly, one end of the strip can be placed over the other in an overlapping manner to fasten these ends of the strip together via the hook and loop fastener formed by this arrangement, whereby the flexible strip forms a closed loop or ring passing through 10 the respective slot 22 in the base of the support bracket.
A short distance above each of the slots 22, a respective pin 34 projects perpendicularly from the leg 28 of the base to which the hook and loop fastener strips are riveted to form male protuberances that jut outward from the base to the side thereof opposite that to which the support arm 14 extends to carry the 15 support rail 16. The pins 34 of the illustrated embodiment are identical and each have a generally oblong cross-section that is horizontally wider than it is vertically tall.
Turning now to Figure 3, the forgoing support bracket is shown in an installed position on a Quick Support Rod 40 to form an assembled crown moulding support tool. The commercially available Quick Support Rod is a telescopically extendable and collapsible pole assembly featuring a first upper pole section having one end thereof slidably disposed within a second lower pole section 44 for telescopic extension and retraction of the upper pole section 42 through an open upper end of the lower pole section in order to increase and descrease the overall length of the assembly between opposing ends thereof that respectively engage the floor and ceiling during use of the tool of the present invention. The lower pole section 44 is of circular cross-section, while the upper pole section 42 of a hollow rectangular configuration of an outer diagonal measure that is less than the inner diameter of the lower pole section so as to fit slidably therein.
A ratchet mechanism 46 is mounted to the lower pole section at the open upper end thereof with a manual control member 46a for engagement and disengagement of a ratchet action of the mechanism. In a side of the rectangular upper pole section 42 that faces the side of the lower pole section on which the ratchet mechanism is mounted, a series of rectangular holes 48 are provided in a manner spaced apart equally from one to the next along the longitudinal axis of the linearly extending upper pole section. When the ratchet mechanism is engaged in its normal default state, the ratchet member is biased so as to automatically engage with one of the holes 48 in the upper pole section.
The shape of the ratchet member is such that it will resist, but not fully block, sliding of the upper pole section in the direction extending the same from the lower pole section, and on the other hand will fully prevent sliding of the upper pole section in the direction retracting the same further back into the lower pole section.
Accordingly, the user can pull upward on the upper pole section in order to draw more of the upper pole section from out of the lower pole section, and thereby increase the overall length of the pole assembly. The ratchet will retain this length via the biased default engagement of the ratchet member with one of the holes in the upper pole assembly. The automatic locking of ratchet mechanism prevents the tool from collapsing by blocking sliding of the upper pole section in the retracting direction back into the lower pole section,until such time as the user manipulates the ratchet control member out of its default position in order to disengage the ratchet and allow free sliding of the upper pole section back into the lower pole section.
At a free top end of the upper pole section 42 outside the lower pole section 44, the pole assembly features a pivot mount 50a atop which is carried a pad of resilient material 52a. The pivot mount supports the pad 52a in a manner pivotal about an axis perpendicular to the coincident axes of the linear pole sections 42, 44, whereby the pad is pivotal about a horizontal axis when the pole sections are vertically oriented. A similar pivotal pad configuration 50b, 52b is provided at the free bottom end of the lower pole section 44 opposite the open upper end of the lower pole section 44 from which the upper pole section 42 extends.
The support bracket 10 is installed on the pole assembly 40 by mating the pin-equipped side of the base member 12 against the hole-equipped side of the upper pole section 42 so that the two pins 34 of the support bracket engage into a respective non-adjacent pair of the holes in the side of the upper pole section 42, whereby the otherwise flat faces of these sides of the upper pole section and base member of the support bracket are placed flush against one another. The distance between the two pins 34 on the base member of the support bracket in the elongated length or height direction of the base member is an integer multiple of the equal distance between any two adjacent ones of the holes 48 in the upper pole section 42, whereby the user can install the support bracket on the pole assembly in any of a plurality of different positions along the upper pole section by engaging the pins 34 of the support bracket into a different pair of holes in the upper pole assembly. The installation of the support bracket onto the pole assembly is completed by securing bracket in place by closing the hook and loop fastener strips 26 around the upper pole section.
The engagement of the pins 34 of the support bracket into the holes of the upper pole section acts to block axial/vertical displacement between the two, and the embracing of the hook and loop fastener strips 26 around the upper pole section prevents lateral/horizontal separation between the base member of the support bracket and the upper pole section. While use of one pin would be sufficient to prevent axial displacement, use of two or more pins additionally prevents by the support bracket from tilting out of alignment with the pole assembly on a horizontal axis parallel to the pins, and thus is preferred over single-pin embodiments of the support bracket. The illustrated embodiment uses pins of rounded oblong, oval-like or elliptical shape to provide a notable filling of the elongated rectangular shape of the openings of the Quick Support Rod ratchet arrangement, while avoiding sharp corners that may make insertion more difficult. However, pins of other cross-sectional shape may be used.
The support bracket is installed in a position such that the support arm 14 and the support rail 16 are situated at an elevation below that of the pivot mount and pad assembly 50a, 52a at the top end of the upper pole section 42. The position of at which the support arm is installed, i.e. the pair of holes at which it is engaged to the upper pole section, is selected such that the difference in height between the top of the pad 52a and the topside of the support arm 14 and support rail 16 is sufficient to accommodate the height of the crown moulding that is to be installed using the tool.
The process of using the forgoing tool assembled from the support bracket and pole assembly begins with the pole assembly in a partially collapsed condition (i.e. an intermediate state between its fully collapsed state of minimum attainable length and its fully extended state of maximum attainable length).
In this partially collapsed state, the overall length of the tool is less than the vertical height measured between a floor surface and an opposing ceiling surface. The pole assembly is manually held in a vertical upright position with the lower pad 50b situated flat against the floor surface at a distance from the wall and with the wall contact surface 20a of the support rail 26 against the surface of the wall onto which the crown moulding is to be installed.
The pole assembly is telescopically extended by the user until the top pad 50a is brought into flush contact with the ceiling, at which point the ratchet mechanism automatically locks the pole assembly at this length, and frictional contact of the pads with the floor and ceiling maintain the extended pole assembly in this vertical orientation standing perpendicularly upright between the floor and ceiling. During this extension of the pole assembly, the wall contact surface 20a slides up the wall, and ends up at a distance below the ceiling as determined by the selected installation position of the support bracket relative to the ceiling-engaging contact pad 50a.
The support arm and rail of the support rod and the top portion of the pole assembly reaching upward past the support bracket to the ceiling cooperate with the ceiling surface and wall surface against which the upper ceiling contact pad 50a and laterally outer wall contact surface 20a are situated in order to define a "box 5 area" or "encapsulating space" like those described in the first two prior art references summarized in the background section of the present application.
Accordingly, one end of the crown moulding can be passed through this space so that the crown moulding sits atop the support arm and rail 14, 16 at a position adjacent to the ceiling/wall joint at which the crown moulding is to be installed. As 10 an alternative to extending the tool into this position prior to placing the moulding on the support bracket, an end-adjacent portion of the moulding may be placed onto the support arm and rail at the position of the support bracket against the wall before extending the pole assembly upward, whereby this end portion of the moulding is raised along with the support bracket during the extension of the pole assembly. A
second tool of the same type may then be used to raise a second end portion of the moulding up to the wall/ceiling joint, whereby both end portions of the moulding are supported by the tools so that both hands of the installer are free to make final manual adjustment of the crown moulding piece, and to fasten the same in place at such a finalized installation position.
According to a second aspect of the invention there is provided an accessory for an elongated pole assembly comprising telescopically mating pole sections extendable and collapsible along a longitudinal axis between a floor engagement end of the elongated pole assembly and an opposing ceiling engagement end of the elongated to increase and decrease an adjustable overall length of the pole assembly between the floor engagement end and the opposing ceiling engagement thereof so that the pole assembly can be extended into a self-supporting upright position frictionally engaging opposing floor and ceiling surfaces at the opposing ends of the pole assembly, the accessory comprising:

DETAILED DESCRIPTION
Figure 1 shows a support bracket 10 of one embodiment the present invention designed as an accessory for a commercially available, telescopically extendable and collapsible pole assembly marked as the Quick Support R0dTM by Task Tools ¨ Div. of Caplan Industries Inc. of Delta, British Columbia, Canada. The support bracket is used in order to convert the pole assembly into a suitable tool for supporting crown moulding or other elongated material at an elevated location at the corner joint between an upright wall and intersecting ceiling.
The support bracket features an elongated base member 12 of linearly extending vertical orientation, and a support arm 14 of linearly extending horizontal orientation fixed to and projecting perpendicularly from the base member 12 at the top end thereof. In the illustrated embodiment, each of these members is formed by a respective length of angle iron, but members of other shape and material may alternatively be employed to achieve similar result, as will be appreciated from the following further description of the structure and function of the support bracket. The base and support arm may be mitered at the corner joint between them, as shown Figure 1. A diagonal brace 15 spans obliquely between the base and support arm 12, 14 from near a distal end of the support arm that lies opposite the base to a distance partially down the base 12 from the joint of the base with the support arm.
The brace may be formed of a thin metal bar or strip of metal plate placed flush against coplanar faces of the angle iron base and support arm members 12, 14.
In other embodiments, sufficient joint strength between the base and support arm may omit the need for a reinforcing brace between the two.
A third piece of angle iron defines a right angle support rail 16 fixed to the support arm 14 at the distal end thereof in a horizontally extending position lying perpendicularly cross-wise to the support arm 14. A horizontal leg 18 of the angle iron support rail 16 has its top surface 18a flush with a horizontal top surface 19a of the support arm 14 in place of a cut-away end portion of the horizontal leg 19 of the support arm 14 from which the vertical leg of the support arm's angle-iron structure depends. The topside 18a of the support rail's horizontal leg 18 defines a support surface atop which the crown moulding is seated during use of the support bracket in the manner described herein further below. The vertical leg 20 of the support rail 16 depends downward from the horizontal leg 18 thereof at the edge of the horizontal leg lying furthest from the base member 12 just beyond the distal end of the support arm 14. The surface 20a of this vertical leg facing laterally away from the base member forms a wall engagement element for placement against the wall on which the crown moulding is to be placed at a height spaced downward from the ceiling.
Turning back to the base member 12 of the support bracket 10, a pair of slot-shaped openings 22 are respectively cut through the leg 24 of the angle iron base 12 that lies in a vertical plane perpendicular to the length of the horizontal support rail 16 and to which the diagonal brace 15 is flush mounted. Each of the two slots 22 has an elongated direction lying parallel to the vertical length of the base member 12, and is located nearer a respective one of the top and bottom ends of the base member. A respective strip of flexible material 26 having two opposing free ends and passes through each slot 22, and an intermediate portion of the strip is fastened to the base through the other leg 28 of the base's angle iron shape, which lies in a vertical plane perpendicular to the slotted leg 24 of the base so as to face away from the support arm and rail 14, 16. In the illustrated embodiment, the strip of material is fastened by a rivet 30 that is engaged through the leg 28 of the base, and onward through the flexible strip 26, where it engages a flat washer 32. The flexible strip is thus sandwiched in place between the washer and the leg of the base.
An area of hook material 26a is fixed to one face of the flexible strip to extend at least a partial length of the strip from one free end thereof, and a strip of 5 mating loop material 26b is fixed to the other face of the flexible strip to extend at least a partial length of the strip from the other free end thereof.
Accordingly, one end of the strip can be placed over the other in an overlapping manner to fasten these ends of the strip together via the hook and loop fastener formed by this arrangement, whereby the flexible strip forms a closed loop or ring passing through 10 the respective slot 22 in the base of the support bracket.
A short distance above each of the slots 22, a respective pin 34 projects perpendicularly from the leg 28 of the base to which the hook and loop fastener strips are riveted to form male protuberances that jut outward from the base to the side thereof opposite that to which the support arm 14 extends to carry the 15 support rail 16. The pins 34 of the illustrated embodiment are identical and each have a generally oblong cross-section that is horizontally wider than it is vertically tall.
Turning now to Figure 3, the forgoing support bracket is shown in an installed position on a Quick Support Rod 40 to form an assembled crown moulding support tool. The commercially available Quick Support Rod is a telescopically extendable and collapsible pole assembly featuring a first upper pole section having one end thereof slidably disposed within a second lower pole section 44 for telescopic extension and retraction of the upper pole section 42 through an open upper end of the lower pole section in order to increase and descrease the overall length of the assembly between opposing ends thereof that respectively engage the floor and ceiling during use of the tool of the present invention. The lower pole section 44 is of circular cross-section, while the upper pole section 42 of a hollow rectangular configuration of an outer diagonal measure that is less than the inner diameter of the lower pole section so as to fit slidably therein.
A ratchet mechanism 46 is mounted to the lower pole section at the open upper end thereof with a manual control member 46a for engagement and disengagement of a ratchet action of the mechanism. In a side of the rectangular upper pole section 42 that faces the side of the lower pole section on which the ratchet mechanism is mounted, a series of rectangular holes 48 are provided in a manner spaced apart equally from one to the next along the longitudinal axis of the linearly extending upper pole section. When the ratchet mechanism is engaged in its normal default state, the ratchet member is biased so as to automatically engage with one of the holes 48 in the upper pole section.
The shape of the ratchet member is such that it will resist, but not fully block, sliding of the upper pole section in the direction extending the same from the lower pole section, and on the other hand will fully prevent sliding of the upper pole section in the direction retracting the same further back into the lower pole section.
Accordingly, the user can pull upward on the upper pole section in order to draw more of the upper pole section from out of the lower pole section, and thereby increase the overall length of the pole assembly. The ratchet will retain this length via the biased default engagement of the ratchet member with one of the holes in the upper pole assembly. The automatic locking of ratchet mechanism prevents the tool from collapsing by blocking sliding of the upper pole section in the retracting direction back into the lower pole section,until such time as the user manipulates the ratchet control member out of its default position in order to disengage the ratchet and allow free sliding of the upper pole section back into the lower pole section.
At a free top end of the upper pole section 42 outside the lower pole section 44, the pole assembly features a pivot mount 50a atop which is carried a pad of resilient material 52a. The pivot mount supports the pad 52a in a manner pivotal about an axis perpendicular to the coincident axes of the linear pole sections 42, 44, whereby the pad is pivotal about a horizontal axis when the pole sections are vertically oriented. A similar pivotal pad configuration 50b, 52b is provided at the free bottom end of the lower pole section 44 opposite the open upper end of the lower pole section 44 from which the upper pole section 42 extends.
The support bracket 10 is installed on the pole assembly 40 by mating the pin-equipped side of the base member 12 against the hole-equipped side of the upper pole section 42 so that the two pins 34 of the support bracket engage into a respective non-adjacent pair of the holes in the side of the upper pole section 42, whereby the otherwise flat faces of these sides of the upper pole section and base member of the support bracket are placed flush against one another. The distance between the two pins 34 on the base member of the support bracket in the elongated length or height direction of the base member is an integer multiple of the equal distance between any two adjacent ones of the holes 48 in the upper pole section 42, whereby the user can install the support bracket on the pole assembly in any of a plurality of different positions along the upper pole section by engaging the pins 34 of the support bracket into a different pair of holes in the upper pole assembly. The installation of the support bracket onto the pole assembly is completed by securing bracket in place by closing the hook and loop fastener strips 26 around the upper pole section.
The engagement of the pins 34 of the support bracket into the holes of the upper pole section acts to block axial/vertical displacement between the two, and the embracing of the hook and loop fastener strips 26 around the upper pole section prevents lateral/horizontal separation between the base member of the support bracket and the upper pole section. While use of one pin would be sufficient to prevent axial displacement, use of two or more pins additionally prevents by the support bracket from tilting out of alignment with the pole assembly on a horizontal axis parallel to the pins, and thus is preferred over single-pin embodiments of the support bracket. The illustrated embodiment uses pins of rounded oblong, oval-like or elliptical shape to provide a notable filling of the elongated rectangular shape of the openings of the Quick Support Rod ratchet arrangement, while avoiding sharp corners that may make insertion more difficult. However, pins of other cross-sectional shape may be used.
The support bracket is installed in a position such that the support arm 14 and the support rail 16 are situated at an elevation below that of the pivot mount and pad assembly 50a, 52a at the top end of the upper pole section 42. The position of at which the support arm is installed, i.e. the pair of holes at which it is engaged to the upper pole section, is selected such that the difference in height between the top of the pad 52a and the topside of the support arm 14 and support rail 16 is sufficient to accommodate the height of the crown moulding that is to be installed using the tool.
The process of using the forgoing tool assembled from the support bracket and pole assembly begins with the pole assembly in a partially collapsed condition (i.e. an intermediate state between its fully collapsed state of minimum attainable length and its fully extended state of maximum attainable length).
In this partially collapsed state, the overall length of the tool is less than the vertical height measured between a floor surface and an opposing ceiling surface. The pole assembly is manually held in a vertical upright position with the lower pad 50b situated flat against the floor surface at a distance from the wall and with the wall contact surface 20a of the support rail 26 against the surface of the wall onto which the crown moulding is to be installed.
The pole assembly is telescopically extended by the user until the top pad 50a is brought into flush contact with the ceiling, at which point the ratchet mechanism automatically locks the pole assembly at this length, and frictional contact of the pads with the floor and ceiling maintain the extended pole assembly in this vertical orientation standing perpendicularly upright between the floor and ceiling. During this extension of the pole assembly, the wall contact surface 20a slides up the wall, and ends up at a distance below the ceiling as determined by the selected installation position of the support bracket relative to the ceiling-engaging contact pad 50a.
The support arm and rail of the support rod and the top portion of the pole assembly reaching upward past the support bracket to the ceiling cooperate with the ceiling surface and wall surface against which the upper ceiling contact pad 50a and laterally outer wall contact surface 20a are situated in order to define a "box 5 area" or "encapsulating space" like those described in the first two prior art references summarized in the background section of the present application.
Accordingly, one end of the crown moulding can be passed through this space so that the crown moulding sits atop the support arm and rail 14, 16 at a position adjacent to the ceiling/wall joint at which the crown moulding is to be installed. As 10 an alternative to extending the tool into this position prior to placing the moulding on the support bracket, an end-adjacent portion of the moulding may be placed onto the support arm and rail at the position of the support bracket against the wall before extending the pole assembly upward, whereby this end portion of the moulding is raised along with the support bracket during the extension of the pole assembly. A
second tool of the same type may then be used to raise a second end portion of the moulding up to the wall/ceiling joint, whereby both end portions of the moulding are supported by the tools so that both hands of the installer are free to make final manual adjustment of the crown moulding piece, and to fasten the same in place at such a finalized installation position.
Alternatively, a single tool of the present invention may be used to support the moulding near one end thereof, with the other end being subsequently lifted and supported manually during the final adjustment and fastening process.
However, use of two tools to support the moulding near both ends thereof may provide the most user-friendly experience and most accurate results.
As another alternative, more than two tools may be used, for example for notable lengths of moulding where one or more intermediate supports may be required between the tool-supported end portions of the moulding. Figure 5 illustrates a tool in use at an intermediate point along the wall/ceiling joint in order to provide intermediate support to a length of crown moulding 60 while an installer standing on a stepladder fine-tunes the position of the moulding within the joint and fastens the same in place with a nail gun, all without the aid of an assistant due to the support of the moulding by two or more of the tools at spaced apart positions along the length of the moulding.
While the illustrated embodiment uses rivets to hold the hook and loop fastener strips 26 in place and uses separate pins to engage the support bracket to the telescopic pole assembly, another embodiment features use of screws to perform both of these functions. In this embodiment, each fastener strip 26 still passes through a respective slot shaped opening 22, but is not held in place by a rivet. Instead, a screw is driven through the fastener strip and the pole-facing leg of the base from the side of this leg that faces away from the pole so that the head of the screw holds the fastener strip in place against this leg in order to secure the fastener strip to the base of the bracket. On the other side of this leg of the base, the shaft of the screw projects outward from this pole-facing side of the base so as to define a respective one of the pins 34 for insertion into the ratchet holes 48 that open into the upper pole section 42 of the pole assembly 40.
As another alternative, more than two tools may be used, for example for notable lengths of moulding where one or more intermediate supports may be required between the tool-supported end portions of the moulding. Figure 5 illustrates a tool in use at an intermediate point along the wall/ceiling joint in order to provide intermediate support to a length of crown moulding 60 while an installer standing on a stepladder fine-tunes the position of the moulding within the joint and fastens the same in place with a nail gun, all without the aid of an assistant due to the support of the moulding by two or more of the tools at spaced apart positions along the length of the moulding.
While the illustrated embodiment uses rivets to hold the hook and loop fastener strips 26 in place and uses separate pins to engage the support bracket to the telescopic pole assembly, another embodiment features use of screws to perform both of these functions. In this embodiment, each fastener strip 26 still passes through a respective slot shaped opening 22, but is not held in place by a rivet. Instead, a screw is driven through the fastener strip and the pole-facing leg of the base from the side of this leg that faces away from the pole so that the head of the screw holds the fastener strip in place against this leg in order to secure the fastener strip to the base of the bracket. On the other side of this leg of the base, the shaft of the screw projects outward from this pole-facing side of the base so as to define a respective one of the pins 34 for insertion into the ratchet holes 48 that open into the upper pole section 42 of the pole assembly 40.
The support bracket may be sold alone as an add-on accessory for a Quick Support Rod or other extendable/collapsible pole assembly. Alternatively or additionally, a complete tool kit including both the bracket and the pole assembly may be packaged or bundled together. It will be appreciated that the benefits of a support bracket that can be secured in place to the side of a extendable/collapsible pole assembly at different heights therealong may be gained regardless of the details of whether the support bracket is fully detachable, and how the bracket and pole assembly mates and fastens to the pole assembly if they are detachable from one another. Likewise, benefits of the support bracket and extendable collapsible pole can be gained regardless of whether the telescoping pole sections are locked together at the selected extended length by a ratchet mechanism like that of the Quick Support Rod, or by some other known mechanism for locking together telescopically mated members at a selected one of a plurality of different attainable lengths. However, the illustrated embodiment in which elements of the ratcheting mechanism double as elements of the fastening system for attaching the support bracket to the pole assembly may provide some added benefit or advantage over other embodiments.
In yet another embodiment, male-female engagement of male protuberances on one of the support bracket and the pole assembly with female openings in the other may be used as part of the attachment system between the support bracket and pole assembly regardless of whether either of the male or female features provides a secondary purpose, such as being part of a ratchet type mechanism for controlling telescopic movement of the pole sections. In such case, the male features may even be provided on the pole assembly instead of on the support bracket, provided they do not interfere with the telescopic extension and retraction of the pole assembly. While in the illustrated embodiment the upper pole section is the pole section of smaller cross-section that fits inside a lower pole section of larger cross-section, this arrangement may be reversed in other embodiments. Use of pole assemblies having more than two telescopic sections is also within the scope of the present invention, although the greater simplicity of the two section pole assembly may have benefits or advantages.
It will be appreciated that the terms horizontal and vertical are used above to denote the orientation in which the support bracket and pole assembly are illustrated, which correspond to the orientation of these elements when used in the context of a truly vertical wall disposed between truly horizontal wall and ceiling surfaces. However, it will be appreciated that such surfaces are not always completely true, and that the upright orientation of the pole assembly accordingly may not be 100% vertical during use. Use of pivotal contact pads at the ceiling and floor ends provides some accommodation for a substantially vertical pole orientation even where the floor or ceiling surfaces may deviate from truly parallel or truly horizontal orientations. However, embodiments lacking pivotal floor or ceiling contact or engagement elements are still contemplated within the scope of the present invention. Features other than generally flat pads may also be used at the points of the contact with the floor and ceiling, just as the particular shape and configuration of topside of the support bracket on which the crown moulding sits may depart from the illustrated configuration of a coplanar surfaces of a support arm reaching from the pole assembly and a perpendicularly rail at the distal end of this support arm.
Manual installation and repair of crown moulding can be difficult, time consuming, dangerous and often requires more than one worker. Lack of assistance in any installation, removal or repair of crown moulding can cause time delays, as well as potential fixture and structure damage. Users can also harm themselves and others if moulding is not properly installed. A safe and effective solution is needed for individuals who want to install or repair crown moulding without the help of someone else.
The Crown Moulding Support Bracket of the illustrated embodiment provides users with an easier way to install crown moulding when working alone. Briefly summarized, the illustrated embodiment includes a bracket attached to an adjustable pole braced between the floor and ceiling against a wall. It allows for the measuring, adjusting, installing, repairing and removing of crown moulding. The assistance of another user, or nails or screws to implement a temporary wall-mounted support are eliminated, as the bracket secures the crown moulding in place without causing damage or danger.
Professional carpenters, property restorers, DIY specialists or the everyday layman may also appreciate this time saving and handy tool.
The Crown Moulding Support Bracket can be used to aid one person in the installation, removal or repair of crown moulding. The resulting tool comprises a metal bracket (a gallows bracket with an extra perpendicular arm or rail) that can be attached to an adjustable or non-adjustable pole to be used in the fitting and fixing of crown moulding. With the assistance of two brackets, a user can easily fit and fix long lengths of crown moulding on his or her own without the aid of another user. The moulding can maneuver with ease within the devices to be marked for cutting internal or external miter joints, 5 eliminating the chance of falling or damaging the moulding. As described and illustrated, the support bracket may have a hook and loop fastener strip that could be woven through slits on the support bracket, which would then be attached to the pole.
The pole may be braced between the floor and the ceiling, against 10 the wall to allow for measuring, adjusting or fixing the crown moulding without causing damage to the moulding, walls or ceiling. No nails or screws would be required to support the moulding during the process. To prevent any damage to the surfaces that come into contact with the moulding, a thin soft vinyl or fabric may cover the sharp edges of the device. The invention may measure 14" high, 15 10" long and 5 1/2" wide in one embodiment, although these measurements are presented as examples only.
A person may use brackets to hang a long section of moulding.
One end may be slid into place along the ceiling using the bracket. Then the other end may be lifted into place and the pole then braced between floor and 20 ceiling. The brackets hold the moulding in place while the user secures it with a pin gun. The exact specifications, materials used, and method of use of Crown Moulding Support Bracket may of course vary.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
In yet another embodiment, male-female engagement of male protuberances on one of the support bracket and the pole assembly with female openings in the other may be used as part of the attachment system between the support bracket and pole assembly regardless of whether either of the male or female features provides a secondary purpose, such as being part of a ratchet type mechanism for controlling telescopic movement of the pole sections. In such case, the male features may even be provided on the pole assembly instead of on the support bracket, provided they do not interfere with the telescopic extension and retraction of the pole assembly. While in the illustrated embodiment the upper pole section is the pole section of smaller cross-section that fits inside a lower pole section of larger cross-section, this arrangement may be reversed in other embodiments. Use of pole assemblies having more than two telescopic sections is also within the scope of the present invention, although the greater simplicity of the two section pole assembly may have benefits or advantages.
It will be appreciated that the terms horizontal and vertical are used above to denote the orientation in which the support bracket and pole assembly are illustrated, which correspond to the orientation of these elements when used in the context of a truly vertical wall disposed between truly horizontal wall and ceiling surfaces. However, it will be appreciated that such surfaces are not always completely true, and that the upright orientation of the pole assembly accordingly may not be 100% vertical during use. Use of pivotal contact pads at the ceiling and floor ends provides some accommodation for a substantially vertical pole orientation even where the floor or ceiling surfaces may deviate from truly parallel or truly horizontal orientations. However, embodiments lacking pivotal floor or ceiling contact or engagement elements are still contemplated within the scope of the present invention. Features other than generally flat pads may also be used at the points of the contact with the floor and ceiling, just as the particular shape and configuration of topside of the support bracket on which the crown moulding sits may depart from the illustrated configuration of a coplanar surfaces of a support arm reaching from the pole assembly and a perpendicularly rail at the distal end of this support arm.
Manual installation and repair of crown moulding can be difficult, time consuming, dangerous and often requires more than one worker. Lack of assistance in any installation, removal or repair of crown moulding can cause time delays, as well as potential fixture and structure damage. Users can also harm themselves and others if moulding is not properly installed. A safe and effective solution is needed for individuals who want to install or repair crown moulding without the help of someone else.
The Crown Moulding Support Bracket of the illustrated embodiment provides users with an easier way to install crown moulding when working alone. Briefly summarized, the illustrated embodiment includes a bracket attached to an adjustable pole braced between the floor and ceiling against a wall. It allows for the measuring, adjusting, installing, repairing and removing of crown moulding. The assistance of another user, or nails or screws to implement a temporary wall-mounted support are eliminated, as the bracket secures the crown moulding in place without causing damage or danger.
Professional carpenters, property restorers, DIY specialists or the everyday layman may also appreciate this time saving and handy tool.
The Crown Moulding Support Bracket can be used to aid one person in the installation, removal or repair of crown moulding. The resulting tool comprises a metal bracket (a gallows bracket with an extra perpendicular arm or rail) that can be attached to an adjustable or non-adjustable pole to be used in the fitting and fixing of crown moulding. With the assistance of two brackets, a user can easily fit and fix long lengths of crown moulding on his or her own without the aid of another user. The moulding can maneuver with ease within the devices to be marked for cutting internal or external miter joints, 5 eliminating the chance of falling or damaging the moulding. As described and illustrated, the support bracket may have a hook and loop fastener strip that could be woven through slits on the support bracket, which would then be attached to the pole.
The pole may be braced between the floor and the ceiling, against 10 the wall to allow for measuring, adjusting or fixing the crown moulding without causing damage to the moulding, walls or ceiling. No nails or screws would be required to support the moulding during the process. To prevent any damage to the surfaces that come into contact with the moulding, a thin soft vinyl or fabric may cover the sharp edges of the device. The invention may measure 14" high, 15 10" long and 5 1/2" wide in one embodiment, although these measurements are presented as examples only.
A person may use brackets to hang a long section of moulding.
One end may be slid into place along the ceiling using the bracket. Then the other end may be lifted into place and the pole then braced between floor and 20 ceiling. The brackets hold the moulding in place while the user secures it with a pin gun. The exact specifications, materials used, and method of use of Crown Moulding Support Bracket may of course vary.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
