Definitions

  • the present invention relates to a tool for caulking joints or fillets for example between building components such as bricks, tiles etc.
  • a nozzle the width of the extrusion aperture, which corresponds to the width of the joint to be caulked.
  • Such nozzles are generally made of a rigid synthetic material with the result that if the joints are not of uniform width or if the edges of the joint are jagged or broken, which is often the case, a satisfying caulking operation cannot be effected.
  • the joint may not become completely filled where it is wider than the extrusion aperture of the nozzle, or the edges of the joint may become smeared with the caulking material used, where the joint is narrower.
  • a tool such as a [caulking pen ? (DK: "Fuge pen”)?] is used to distribute the caulking material evenly and correctly in the joint after the application.
  • DK "Fuge pen”
  • attempts have been made to incorporate the caulking pen functionality into the nozzle of e.g. the caulking gun. The various attempts have resulted in tools that were good at performing certain operations but were not poor at others.

Description

CAULKING TOOL
The present invention relates to a tool for caulking joints or fillets for example between building components such as bricks, tiles etc.
BACKGROUND ART In the building industry, it is customary when e.g. caulking joints between building components, e.g. facing stones, to use a nozzle the width of the extrusion aperture, which corresponds to the width of the joint to be caulked. Such nozzles are generally made of a rigid synthetic material with the result that if the joints are not of uniform width or if the edges of the joint are jagged or broken, which is often the case, a satisfying caulking operation cannot be effected. For example, the joint may not become completely filled where it is wider than the extrusion aperture of the nozzle, or the edges of the joint may become smeared with the caulking material used, where the joint is narrower.
Typically, in order to correct the result after application of the caulking material to the joint, a tool such as a [caulking pen ? (DK: "Fuge pen")?] is used to distribute the caulking material evenly and correctly in the joint after the application. Thus, it is necessary for the operator to divide the procedure of caulking joints into several steps using different tools for each step, and where the operator needs to change back and forth between tools in order to provide a correct fillet or correctly caulked joint. In order to overcome this disadvantage, attempts have been made to incorporate the caulking pen functionality into the nozzle of e.g. the caulking gun. The various attempts have resulted in tools that were good at performing certain operations but were not poor at others. Such devices for performing various specialized caulking tasks are disclosed in e.g. British patent 1,026,463, US patent 5,017,113 and EP 0 106 387. It is a drawback of those devices that they are specialized for a particular task, e.g. corners or a special fillet shape. This means that the user must have wide spectrum of different types of tools, and change between them depending on the joint (gap, crack) , resulting an inefficient work process.
Therefore, there is a need for a tool that may be applied to a caulking gun or other another device for delivery of caulk/plaster, glue , silicone or the like that allows for efficient a application and distribution of the caulking material in one operation for all widths of joints/fillets and for all types of fillet shapes.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
In the following detailed description of the caulking tool, the invention will be described by the preferred embodiments .
However, first Figs. 1A and IB shows a standard prior art caulking nozzle 200. The caulking nozzle 200 comprises an elongate body portion 10 having a longitudinal axis A, an inlet 11 formed at an inlet end 11' , an outlet 12 formed at an opposed outlet end 12' , and a tapering tubular portion 13 stretching there between. At the inlet end 11' an attachment portion 14 typically is provided, the attachment portion 14 forming a straight cylinder formed part, being adapted for attachment to a source of caulking material (not shown) . The attachment portion 14 typically is configured for stable and releasable attachment to the source of caulking material, e.g. by being provided with an internal threading 15 adapted for cooperation with an external threading (not shown) on the source of caulking material. Such nozzles are well known in the art e.g. for cooperating with glue or silicone filler cartridges for us in a caulking gun. Typically such nozzles are formed in plastic. The tapering portion of the nozzle may be provided with markings or may be stepwise tapering. Thus the size of the nozzle outlet may be adapted by cutting a portion of the tip or outlet end of the nozzle.
Fig. 2A-C shows a first exemplary embodiment of a caulking tool 1, according to the invention. The caulking tool 1 comprises an elongate body portion 10 having a longitudinal axis A, a first opening 11 formed at a first opening end 11' , a second opening 12 formed at a second opening end 12' opposite to said first opening end 11' , and a tapering tubular portion 13 stretching there between. At the inlet end 11' an attachment portion 14 typically is provided, the attachment portion 14 forming a straight cylinder formed part, being adapted for attachment to a source of caulking material (not shown) . The attachment portion 14 typically is configured for stable and releasable attachment to the source of caulking material, e.g. by being provided with an internal threading 15 adapted for cooperation with an external threading (not shown) on the source of caulking material (not shown) .
A caulking vane component 20 comprising a caulking vane 20' is formed as an extension of said elongate body portion (10) at the outlet end 12'.
The vane 20' comprises a substantially straight front edge 21, and two side edges 22, 23, which are configured to extend from the outlet 12 to end points 21' , 21' ' of the straight front edge 21. The end points 21', 21'' may not be points as such (i.e. in the mathematical sense) but rounded end areas forming a smooth transition to the side edges 22 and 23. Preferably the vane 20' extends entirely in front of the said outlet. Thus, in this embodiment no portion of the vane 20' extends sideways of or behind the vane 20' . Thus, the vane 20' is preferably substantially triangular in shape. By substantially triangular, in this application is meant that thee vane 20' does not form a perfect triangle, in that transition between the vane 20' and the elongate body portion 10 is not a mathematically defined point, but a bridge 24 between the parts 10, 20' having a width. Further, as described above the transitions between the side edges 22, 23 and the front edge 21 may be rounded, and yet further the side edges 22, 23 may be curved. In any case preferably the vane 20' is as narrow as the outlet end 12', i.e. the width of the bridge 24 is the same or less than the width of the body portion 10 at the outlet end. This ensures a better view to the workplace for user of the caulking tool 1.
The vane 20' defines a plane, P. The surfaces of the vane 20' preferably further constitute closed planes in the sense that they are devoid of openings or holes through the vane 20' .
The plane, P, of the vane 20' forms an angle, VI, of 0- 10°, such as 1-8° or 1-5° relative to the longitudinal axis, A, of the elongate body portion 10
A first surface 25 of the vane 20' , facing the second opening 12 of the elongate body portion 10, and thereby the plane P of said vane 20' is arranged at the second opening 12 such that the first surface 25 is substantially flush with the second opening 12 forming an outlet for the caulking material in this embodiment. By substantially flush, in this patent application is meant that the surface is located and arranged such as to allow a flow of caulking material through the second opening 12 and directly out in the same plane as the first surface 25 of the vane 20' . However in order to allow for production irregularities and a step between the first surface 25 and the second opening as defined by the inner wall 12'' at the transition to the bridge 24 may be allowed, e.g. as shown in Fig. 3, if the step is confined to 1-3 mm or 1-3 times the material thickness wall thickness of the elongate body portion 10 at the second opening end 12' .
The straight front edge 21 of the vane 20' extends to two sides of the second opening 12. The straight front edge 21 forms a second angle, V2, relative to said longitudinal axis, A, in the interval of 95-110°.
Preferably, said vane 20' is formed in a rigid material. Preferably, the tapering tubular portion 10 is also formed in rigid material. The vane 20' is preferably rigidly connected to the tubular portion 10. By rigid, in this application is meant that the vane 20' and the connection or bridge 24 to the elongate body portion 10 are dimensioned and the materials are so chosen as to prevent bending of the vane 20' relative to the elongate body portion 10 under normal use with normal caulking material. Thus, the materials and the dimensioning may be adapted to different kinds of caulking material, depending on their viscosity etc. The vane 20' and/or said tubular portion 10 of the caulking tool 1 may be formed in a rigid polymer material.
Preferably, and as shown in Fig. 2, the vane 20' and said elongate body portion 10 of the caulking tool 1 are formed as one integral item. The caulking tool 1 may be formed in plastic, and may be injection molded in one piece. These embodiments will be especially suitable for cooperating with glue or silicone filler cartridges for use in a caulking gun. However in other embodiments the caulking tool 1 may be formed from separate parts and assembled to form a single unit.
In alternative embodiments said vane 20' and/or said tubular portion 10 may be formed in a metal, such as stainless steel. Preferably, both are formed in metal. Again the caulking tool 1 may be formed as a single unit, or the vane 20' and the tubular portion 10 may be formed separately, and assembled before use. The two parts, the vane 20' and the tubular portion 10, may be assembled by the vane 20' or the tubular portion 10 having a spike corresponding with a channel formed in the other part. E.g. a spike may preferably be formed on the vane 20' in extension of the bridge 24, the spike cooperating with a channel formed in the sidewall of the tubular portion 10. The pike and the channel may form an interference fit. Preferably, the spike and the channel may be configured with means to snap on to each other, e.g. a grating or bayonet fitting. These embodiments with the spike and channel are not shown in the figures. In other embodiments the vane 20' and body portion 10 are formed integrally in a metal. The embodiments, where the caulking tool is formed all in metal are particularly useful when mortar for caulking furrows in brick walls is to be used with the caulking tool 1.
In the above embodiments of the caulking tool 1, a vane component 20 comprising a vane 20' and a bridge 24 thus is fixed to a nozzle comprising an elongate body portion 10.
Figs .4A-C shows another embodiment of a caulking tool 1, where the caulking tool 1 has a separate caulking vane component 20, adapted e.g. for mounting on a standard caulking nozzle 200 or a slightly amended caulking nozzle. The separate caulking component 20 has a vane 20' generally as described for the embodiments above. The vane 20' extends from an elongate body portion 40 having a longitudinal axis B, a first opening 41 for receiving a caulking nozzle, the first opening 41 formed at a first opening end 41' of the elongate body portion, a second opening 42 formed at a second opening end 42' opposite to said first opening end 41', and a tapering tubular portion 43 stretching there between. The elongate body portion 40 is hollow, and the tapering tubular portion 43 is adapted to fit at least partially over a corresponding tapering tubular portion 13 of the standard caulking nozzle 200. Thus, the caulking vane component 20 may be attached to the standard caulking nozzle 200, e.g. by an interference fit.
However, in one embodiment and as shown in Figs. 4B and 4C, the caulking vane component 20 may be provided with an attachment portion 44 on an inner surface 43' of the tubular portion 43. The attachment portion 44 may be provided by a serrated or grated area that will increase the grip or friction between the caulking vane component 20 and the standard caulking nozzle 200. In other embodiments, the attachment portion 44 may be provided by a threading. The threading may in itself increase the friction, similar to the grated or serrated area described above. However, the threading may also be configured for cutting a threading into the relatively- soft plastic material of the outer surface of a standard caulking nozzle 200, e.g. by choice of a suitable hard material for the tubular portion 43 or at least the threaded part 44. The attachment portion 44 may extend over the entire length of the inner surface 43' of the tubular portion 43 or only over a portion thereof, as shown in Figs. 4B and 4C. In other embodiments the caulking nozzle may be a modified standard caulking nozzle 200. In such embodiments (not shown) , the caulking nozzle may be provide with a grating or serrated area (not shown) on the outer surface 13' of the tubular portion 13 corresponding to the inner surface 43' of the caulking vane component 20. In yet other embodiments the (not shown) , the caulking vane component 20 and the outer surface 13' of the tubular portion 13 may be provided with cooperating threading, grating or serrated areas.
In use, the caulking vane component 20 is placed over the calking nozzle such that the elongate axis B of the caulking vane component 20 is aligned with the elongate axis A of the caulking nozzle, as illustrated in Fig. 4A. Preferably, the dimensions of the caulking vane component 20 are chosen such that the outlet 12 of the caulking nozzle just barely passes the second opening end 42' of the caulking vane component 20. If necessary, and if the caulking nozzle is formed in plastic, then a suitable portion of the tip (outlet end 12' ) of the caulking nozzle may be cut off such that a caulking material may be delivered from the outlet 12 of the caulking nozzle and onto the surface 25 of the vane 20' of the caulking vane component 20. The vane 20' is connected to the elongate body portion 40 as an extension of the elongate body portion 40, and formed at the second opening end 42' thereof. A bridge 46 provides a transition from the elongate body portion 40 to the vane 20' . The caulking vane 20, and it's parts (the vane 20' , the elongate body portion 40 and the bridge 46) may in essence be formed in the same manner as described above for the caulking tool 1 in the Figs. 2A-C and 3 embodiments, i.e. where the elongate body portion 40 of the caulking vane 20 corresponds to the elongate body portion 10 of the caulking tool 1.
The length of the bridge 46 may vary such that the location of the vane 20' is aligned with the outlet 12 of the caulking nozzle 200, depending on the location of the attachment of the caulking vane 20 to the caulking nozzle 200. The length of the tapering tubular portion 43 may be varied to determine the location of the fitting to the tubular portion 13 of the caulking nozzle 200.
Figs. 5A-D show another embodiment of a caulking tool 1 with a separate caulking component 20. In this embodiment the caulking tool 1 also comprises a caulking nozzle 1' and a caulking vane component 20. The caulking tool 1 in this embodiment differs from the embodiments described in connection with Figs. 4A-C in that the caulking nozzle 1' is specially adapted for the caulking vane component 20, by having a vane connection portion 16 where at least an outer surface 16' thereof has a straight cylindrical shape, and wherein the outer surface 16' is configured for connection to the caulking vane component 20. An assembly of a caulking vane component 20 mounted on a caulking nozzle 1' is shown in Fig. 5A. A perspective view of the caulking nozzle 1' is shown in Fig. 5B and in Fig. 5C a sectional view of the caulking nozzle 1' is shown. Fig. 5 D shows a perspective view of the caulking vane component 20.
Thus, the caulking nozzle comprises an elongate body portion 10 having a longitudinal axis A, an inlet 11 formed at an inlet end 11' , a second opening 12 formed at an opposed outlet end 12' , and a tapering tubular portion 13 stretching there between. The tapering tubular portion 13 may be divided in two separate areas 13'' and 13''' (see Fig. 5B) by the vane connection portion 16.
At the inlet end 11' of the nozzle 1', an attachment portion 14 is provided, the attachment portion 14 forming a straight cylinder formed part, being adapted for attachment to a source of caulking material (not shown) . The attachment portion 14 typically is configured for stable and releasable attachment to the source of caulking material, e.g. by being provided with an internal threading 15 adapted for cooperation with an external threading (not shown) on the source of caulking material.
In this embodiment, an inner surface 13' may form the shape of an uninterrupted cone, which will ease the passage of the caulking material.
The elongate body portion 10 further comprises a vane connection portion 16 where at least an outer surface 16' thereof has a straight cylindrical shape. The outer surface 16' is configured for connection to the caulking vane component 20. This means that the caulking vane component 20 has an elongate body portion 50 which is correspondingly straight cylindrical in shape, at least at an internal surface 58 thereof. Thereby, the caulking vane component 20 and the vane connection portion 16 are adapted to cooperate. In a preferred embodiment said outer surface 16' is provided with a threading 17 configured for cooperating with a threading 57 on an inner surface of the caulking vane component 20. However, in other embodiments (not shown) , the connection between the outer surface 15' and the caulking vane component 20 may be provided by an interference/frictional fit, e.g. supplemented with a grating or serrating on either or both parts. Alternatively or additionally, the connection may be provided with e.g. one or more snap-locks to provide a stable connection.
The separate caulking component 20 has a vane 20' generally as described for the embodiments above. The vane 20' extends from an elongate body portion 50, the elongate body 50 having a longitudinal axis B, a first opening 51 for receiving the caulking nozzle 1' , the first opening 51 formed at a first opening end 51' of the elongate body part, a second opening 52 formed at a second opening end 52' opposite to said first opening end 51' , and a straight cylindrical tubular portion 53 stretching there between. The elongate body portion 50 is hollow, and the straight cylindrical tubular portion 53 is adapted to fit at least partially over a correspondingly straight cylindrical vane connection portion 16 of the caulking nozzle 1' .
A bridge 56 forms a transition from the elongate body portion 50 to the vane 20' . The length of the bridge may be adapted, according to the distance from the outlet end 12' of the nozzle 1' to where the elongate body portion 50 of the vane component 20 is connected to the vane connection portion 16 of the nozzle 1'. Preferably, the length of the bridge is adapted such that the outlet 12 of the nozzle 1' is positioned behind the vane 20' such that a caulking material may be delivered from the outlet 12 of the caulking nozzle and onto the surface 25 of the vane 20' of the caulking vane component 20. In other embodiments the, if the caulking nozzle is formed in plastic, then a suitable portion of the tip (outlet end 12' ) of the caulking nozzle 1' may be cut off such that a caulking material may be' delivered from the outlet 12 of the caulking nozzle and onto the surface 25 of the vane 20' of the caulking vane component 20.
In some embodiments, the caulking vane component 20 may be lengthwise adjustment on the vane connection portion 16 of the caulking nozzle 1' .
Fig. 6 shows another embodiment of a modified caulking nozzle 1' configured for cooperation with a separate caulking vane component 20. In this embodiment, the modified caulking nozzle 1' has a longer vane connection portion 16, which is of straight cylindrical shape, such that the vane connection portion 16 extend between a conical portion 13 and an attachment portion 14. Thereby the interior of the nozzle 1' does not form an uninterrupted conical shape as in the embodiments described in connection with Figs. 5A-D.
Figs. 7 A and 7B show alternative embodiments of vane component 20, 'where the vane 20' has different shapes. These shapes may be combined with any of the embodiments described above.
Fig. 8 shows an alternative embodiment of vane component 20, where the vane 20' has markings or weakened lines 60 adapted for aiding in cutting off a portion of the vane 20' to adapt the vane 20' width and/or area. This feature may be combined with any of the embodiments described above .
The invention according to the embodiments described above is suitable for caulking different widths of fillets and is suitable for performing the filling of the fillet and the adj ustment/pressing of the applied caulking material in one operation by a user. Further, it has been found that the shape and position of the vane 20' allows efficient caulking in places that usually considered inaccessible such as corners The invention according to the embodiments described above may be applied to caulking with e.g. mortar. Especially, the embodiments with a fixed vane may be used in this connection. The caulking tool according to the invention may work together with various delivering mechanisms for delivering caulking material. In particular a caulking tool could also be connected to a gun type unit which in turn could be connected via suitable tubing to a reservoir or source of caulking material. With a suitable delivery pressure such delivery to the nozzle may be applied over a considerable distance. Although the teaching of this application has been described in detail for purpose of illustration, it is understood that such detail is solely for that purpose, and variations can be made therein by those skilled in the art without departing from the scope of the teaching of this application.
