Abstract:
A multi-purpose automatic handheld installation tool for installing and removing vinyl and plastic resilient bumper inserts into the channels of gunnel rails on the sides of boats, vehicles, motorhomes, trailers, and the like, as well as on the sides of tables, walls and shelves. The tool compresses sides of bumper inserts in order to be easily inserted to the channels of the gunnel rails. A base handle and a secondary handle allow for easy holding of the weight of the tool. The tool handle is oriented to run consistently parallel over the gunnel rails when being used. A guide member allows the tool to follow the path and direction of the gunnel rails, and allows the tool to be consistently maintained at an inclined position and where the handle is substantially parallel overlaying the gunnel rails without having to free-hand support the orientation of the tool. The tool can be powered by a battery or a wall plug power source or pneumatic source. A second embodiment allows the tool be used as a adapter having having a chuck head for attachment and detachment to conventional handheld power tools such as but not limited to power drills, power screw drivers, and the like. Bumper insert material can be removed from the gunnel rail/rub rail by prying up an edge of the insert material feeding it into the wheels of the tool and reversing the installation steps.

Description:
This invention relates to moldings, gunnel rails, and the like, and in particular to tools and methods that install, and removes resilient and compressible bumper materials into the rail channels on the sides of boats, vehicles, trailers, motor homes, and the like, and this invention is a Continuation-In-Part of U.S. application Ser. No. 09/976,541 filed Oct. 12, 2001 now U.S. Pat. Ser. No. 6,523,242, which is a Divisional Application of U.S. application Ser. No. 09/482,406, filed Jan. 12, 2000, now issued as U.S. Pat. No. 6,341,410, which claims the benefit of priority to U.S. Provisional Application Ser. No. 60/116,165 filed Jan. 15, 1999. 

   BACKGROUND AND PRIOR ART 
   Side moldings, gunnel rails and rub rails have been used over the years on boats to join hulls and decks together, where the gunnel rails have resilient materials inserted within their channels. See for example, U.S. Pat. Nos. 3,065,724 to Tritt; and 4,292,913 to Siebert et al. Other similar bumper assemblies have been proposed for vehicles, docks, and the like, that also use similar expandible resilient material inserts inside of channels. See for example, U.S. Pat. No. 3,473,836 to Halter. 
   Problems with these assemblies involve the labor, time and equipment that an installer must use to insert the resilient material into the gunnel rail channels. Typically, in the boating industry, an installer has been required to use multiple tools such as screwdrivers, hammer, pliers, hand spade, putty knives, duck-bill pliers, and the like, to jam, bang and push the resilient insert material into the channels. The current installation techniques are both time consuming and expensive projects in labor costs for the installation. These installation techniques cause scrapes, bumps, dents and tears in the insert material. Additionally, the installation tools often damage the channels and the surrounding surfaces on the boats and vehicles. 
   Under these conventional types of installation methods, the insert material strips often must be heated to soften the material in order for it to be used. The strip materials are generally heated in hot boxes or within hot water tanks. After heating, the strip materials are then installed with the tools described above. Problems occur from these heating techniques. The heating and subsequent cooling of the materials can cause non-uniform shrinkage and inconsistent expansion throughout the strip material within the gunnel rail channels resulting in unsightly bulges and depressions. Furthermore, the installers have received injuries such as damaged hands and other injuries that can and have resulted in workmen&#39;s compensation claims through the installation process. The above problems become compounded when the resilient insert materials need to be removed and replaced over time due to natural wear and use. 
   Over the years various patents have been proposed for the installation of resilient bumpers. For example, U.S. Pat. No. 3,897,967 to Barenyi describes a “protective strip for motor vehicles . . . ”, title, that uses resilient bumpers with backings having expandible plug inserts that pass into recesses in the base walls of the channels. However, this reference requires multiple parts and extra tooling of parts that would not be a practical substitute for existing gunnel rails and rub rails on boats, vehicles, and the like. 
   Other techniques known for inserting resilient bumper strips into channels have included machines. See for example, U.S. Pat. No. 5,758,400 to Miller et al. However, this type of machine would not be a practical alternative for a single user that needs to install the resilient insert bumpers into gunnel rails and rub rails that are already located on the sides of boats, vehicles, and the like. Clearly, this machine would be both expensive in cost and is incapable of being used for already mounted gunnel rails and rub rails. 
   Various handheld tools have also been proposed for installing resilient bumper type strips. U.S. Pat. No. 4,578,851 to Song describes a handheld tool in various embodiments that requires consistently bending the longitudinal length of the rubber molding into “a curve” that appears to approach up to one hundred eighty degrees in order to fit the rubber molding into the handheld tool. Song &#39;851 mentions that having some resilient strips being “bent too sharply, the molding could break, or the frictional resistance of the molding passing through the tool could make the tool hard to use”, column 7, lines 24-27. The embodiments also require having the user physically insert the strip into the initial bent configurations in order to use the tool. Song &#39;851 mentions a power tool version that also requires the user physically bend the resilient strip before running the tool. In addition to having to physically insert the strips, and having to continuously bend the strips, the user will still have to apply some pressure to use the tool as well as having to physically center these tools to be used, and the user will have to maintain a free-hand holding of the tool when being used which would be difficult for large insertion operations. 
   U.S. Pat. No. 5,940,950 to Galat describes an automated “crimping tool for progressively squeezing weather stripping on an elongated thin molding such as around the border of a vehicle door”, abstract. This tool would be difficult to use since it would require the user have to balance the tool in a substantially perpendicular orientation to the strip channel, and the user would have to maintain the position and orientation of the tool in a free-hand application. Additionally, this tool does not allow for the initial easy insertion of the strip into the channels. For example, this tool does not compress the strip for insertion into the channels. 
   Other techniques have been made but also fail to overcome all of the problems described above. See for example, U.S. Pat. Nos. 4,084,533 to Boyer and 4,903,629 to Mauldin et al. Thus, the need exists for solutions to the above problems. 
   SUMMARY OF THE INVENTION 
   The first objective of the present invention is to provide a multipurpose tool and technique to allow a single person the capability of automatically installing and removing resilient bumper insert materials into gunnel rails/rub rails on the sides of boats, vehicles, motorhomes, trailers and the like. 
   The second object of this invention is to provide an inexpensive and multipurpose tool and technique of automatically installing and removing resilient bumper insert materials into gunnel rails/rub rails already located on the sides of boats, vehicles, motorhomes, trailers and the like. 
   The third object of this invention is to provide a tool and technique of automatically installing and removing resilient bumper insert materials inside of gunnel rails/rub rails that does not excessively bend, mark up, scrape, dent, nor destroy the resilient bumper insert material. 
   The fourth object of this invention is to provide a tool and technique of automatically installing and removing resilient bumper insert materials into gunnel rails/rub rails, without marking up, scraping, denting nor destroying the gunnel rails/rub rails. 
   The fifth object of this invention is to provide a tool and technique of automatically installing and removing resilient bumper insert materials into gunnel rails/rub rails, without injuring the installer. 
   The sixth objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials that does not require the installer to have to hold and orient the tool in difficult postions to maintain orientations. For example, the tool handle does not have to be oriented to be substantially perpendicular to the gunnel rails/rub rails. 
   The seventh objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials that allows the user to hold the tool in an easy to use and maintain, and safe consistent orientation when being used that follows the longitudinal direction of the gunnel rails/rub rails. The novel tool allows the user to orient the tool handle body in a parallel orientation facing over the gunnel rails/rub rails during the installation. 
   The eight objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials that allows the user to consistently press a portion of the tool in an easy to use and maintain, and safe consistent orientation against the gunnel rails/rub rails when being used. The novel tool allows the user to further orient the tool body in a slightly angled (tilted/inclined) orientation of approximately 30 degrees when viewed from the side as the tool is positioned adjacent to the gunnel rails/rub rails. 
   The ninth objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials, that uses a guide to allow the user to consistently and automatically follow the longitudinal contour of the gunnel rails/rub rails. 
   The tenth objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials that consistently holds and supports the tool in a consistent orientation that does not require a free-hand holding of the tool itself. Once the tool is oriented in position, the user only has to follow the running tool until the insertion is completed or until the power is turned off. 
   The eleventh objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials that does not require the installer to have to physically insert the strip into the gunnel rails/rub rails prior to being used. 
   The twelvth objective of this invention is to provide a tool and technique for automatically installing and removing resilient bumper insert materials in the form of a versatile adapter for use with existing handheld power tools such as but not limited to power drills, power screw drivers and the like. 
   A first embodiment of the invention includes an automated multi-purpose handheld tool for inserting resilient bumpers into the channels on gunnel rails and rub rails that are located on the sides of vehicles such as boats, motor homes and trailers. The first embodiment automatic tool can include an adapter portion that can be used as a chuck head attachment for conventional power tools such as handheld drills, power screw drivers, and the like. 
   The tool has a first end for a handgrip and a second end with a rotatable rollers and wheels, where the second end is laid over the front portion of the elongated resilient strip and causes the rear portion of the elongated strip to be inserted into the channels on the side of the vehicles. Each of the channels have a rear wall for being attached to the side of the vehicle, and inwardly bending lips for surrounding an opening to the channel, wherein the rear portion of the elongated resilient strip is inserted into the opening of the channel. The elongated resilient strips have a backwall forming the rear portion, the backwall having an upper edge and a lower edge, wherein the upper edge and the lower edge become compressed towards one another when being inserted within the channel and expand when the rollers of the handheld tool passes over the channel. The rotatable wheels and rollers on the second end of the handheld tool have dual rollers separated from one another, wherein the rear portion of the elongated resilient strip is compressed together by the strip passing through the dual rollers. The motor in the conventional power tool base rotates the rollers/wheels. 
   The user simultaneously holds the tool against the channel openings of the gunnel rails and rub rails and slides the tool against the gunnel rails/rub rails at a tilt/inclination angle of approximately 10 to approximately 45 degrees to the gunnel rails/rub rails, while operating the power drill or power device causing the strip material to be inserted into the channel openings. A guide member allows for a selected inclination/tilt angle to remain consistent so that the installer merely has to support the weight of the tool. The longitudinal handle of the tool can be maintained to be substantially parallel to the longitudinal gunnel rail. 
   After the tool passes over a gunnel rail/rub rail base section, portions of the strip material that have been compressed by the action of the wheels, then it expands into the inside lip portions of the gunnel rail/rub rail locking the strip material in place. 
   The strip material can be removed by prying up an edge of the material from the channel of the gunnel rail/rub rail, and using the tool reversing the installation steps described above. 
   The gunnel rails/rub rails with resilient bumpers can be used with other objects such as but not limited to tables, shelves, walls, and the like. 
   A second embodiment of the automated multi-purpose tool has the head portion as being built onto a power tool base. 
   The motor that runs the wheels/rollers can be powered by batteries or be plugged into a wall receptical, or be powered by a pneumatic power supply, and the like. 
   Further objects and advantages of this invention will be apparent from the following detailed description of a presently preferred embodiment which is illustrated schematically in the accompanying drawings.

   Referring to  FIGS. 2A-2F , a first embodiment tool  100  includes a novel adapter head  105  that can be easily attachable and detachable to a conventional type power tool base  190 . Such as power tool base  190  can be a conventional battery operated handheld drill, power screw driver, and the like. The conventional power tool base can include a chuck end  192  having an opening  191  which can be adjustably opened and closed to tighten about a drive shaft  112  on the novel adapter head  105 , the latter of which will be described later. The chuck end  192  can be powered by a conventional motor  195  within longitudinal handle  194 , which can be powered by a conventional battery pack  193  within an end detachable member  198 , where a trigger type switch can be compressed to rotate the chuck end  192  in the direction of arrow R 1 . 
   Referring to  FIGS. 2A-2F , the novel adapter head  105  can include a drive shaft  112 , such as a hexagon shaped shaft, and the like, which protrudes from the head  105  and is attached at an opposite end to a main drive gear bearing  111  that is attached to a rotatable main gear wheel  113  having serrated teeth edges  114 . The exterior serrated teeth  114  of the main gear wheel  113  interconnect with the serrated teeth  116  of right interior gear wheel  117 . The serrated teeth  116  of right interior gear wheel  117  are interconnected with the serrated teeth  118  of left interior gear wheel  119 . A left exterior wheel  125  is connected by a narrower base portion  121  to left interior gear wheel  119  by fasteners  128 , such as screws and the like. Similarly, a right exterior wheel  127  is connected by a narrower base portion  129  to right interior gear wheel  119  by fasteners  128  such as screws, and the like. Left exterior wheel  125  can have knurled edges  124 , and right exterior wheel  127  can have knurled edges  126  for allowing enhanced gripping capability about the bumper insert material  40  which will be described in further detail later. A bottom cap portion  120  has dual openings for allowing the base portions  121 ,  129  to pass therethrough, and bottom cap portion  120  can be fastened to an upper cap portion  130  by fasteners  123  such as but not limited to screws, and the like. 
   Referring to  FIGS. 2A-2F , an anti-rotation bracket  140  can have a base rim portion  142  that can be attached to extend upwardly from upper cap portion  130 , and can be connected to upper cap portion  130  by fasteners  141  such as screws, and the like.

In a preferred embodiment that was reduced to practice, angles A 1  and A 2  can each be approximately 27 degrees. The angle A 2  can be better visualized by turning  FIG. 2E  upside down. Post faces  163 ,  167  can be formed from plastic, and the like. Alternatively, faces  163 ,  167  can include a material such as nylon, and the like, to aid in sliding the tool  100  over the gunnel rails which will be described later. Posts  162 ,  166  attach to a base portion  164  which can have a downwardly protruding triangular tip portion  168  underneath of which can be a slot opening  169  there-through which allows for a bumper insert strip  40  to be described later to pass therethrough. Underneath guide member  160  can be guide track  170  which runs between exterior wheel base portions  121 ,  129  having a longitudinal rounded indentation  175 , where the slot opening  169  is formed where track indentation  175  is adjacent to protruding tip portion  168  of the guide member. 
   The operation of the rotatable components of the first embodiment will now be described in reference to  FIGS. 2B and 2F . To connect the adapter head  105  to tool base  190 , drive shaft  112  is inserted into opening  191  of rotatable chuck end  192  in the direction of arrow I 1 . Operating the tool base  190  and causing the rotating of the chuck end  192  in a counter-clockwise direction as shown by arrow R 1  causes main gear wheel  114  to also rotate in a counter-clockwise direction as shown by arrow R 2 , which causes the right interior gear wheel  117  and exterior right wheel  127  to rotate in a clockwise direction as shown by arrow R 3 . Simultaneously, the clockwise rotating right interior gear wheel  117  causes the left interior gear wheel  130  and exterior wheel  125  to rotate in a counter-clockwise direction as shown by arrow R 4 . 
     FIG. 3A  is a bottom view of the first preferred embodiment  100  with adapter chuck head  105  attached to the power tool base  190 , and rub rail strip  40  inserted within the slot opening  169  of the guide member  160  and the dual exterior wheels  125 ,  127 .  FIG. 3B  is an end view of adapter chuck head  105  with rub rail strip  40  between the dual wheels  125 ,  127  of  FIG. 3A  along arrow  3 B.

   Referring to  FIGS. 3A-3C , an installer can hand insert an end of bumper strip insert  40  into the curved slot opening  169  in guide member  160 , where both the slot opening  169  along with the curved indentation  175  in guide track  170  directs the bumper insert  40  toward exterior wheels  125 ,  127 . When the tool  100  is running, the knurled edges  124 ,  126  of the rotating wheels  125 ,  127 (which can rotate in the clockwise and counter-clockwise directions as shown by arrows R 3  and R 4 , which were previously described) aid in pulling the bumper strip  40  therethrough. As the bumper strip  40  passes through the wheels  125 ,  127  in the direction of arrow P 1 , the upper backing edge portion  42 , a lower backing edge portion  44  which were previously compressed together by the knurled edges  124 ,  126 , can now expand outward(as shown in FIG.  3 A). 
     FIG. 4  is a side view of the first preferred embodiment multi-purpose tool  100  with inserted rub rail insert strip  40  of  FIGS. 3A-3C  separate from and ready to install the rub rail insert strip  40  into the channel within the surface mounted gunnel rail  30 (such as the boat mounted side gunnel rail  30  previously described in reference to  FIGS. 1A-1C . Referring to  FIG. 4 , the tool  100  can be simultaneously supported and held by a left hand  50  of a user about handle portion  155  of gripping handle  150 , and by a right hand  60  of a user about the longitudinal housing  194  of tool base  190  with the entire tool body oriented at an angle A 1 /A 2 . As previously described angles A 1 /A 2  can be between approximately 10 degrees and approximately 45 degrees for maximum ease for using the tool  100 . A working prototype of the invention was reduced to practice using an inclination angle A 1 /A 2  of approximately 27 degrees. A trailing edge portion of the tool  100  where the bottom most inclined edge of wheel  125  is lowered in the direction of arrow L 1  to be adjacent to mounted end member  12  of the channel  30  in order to allow a bumper insert end  49  which extrudes out from the wheels ( 125  is only shown) in the direction of arrow P 1  to be inserted into the channel opening within gunnel rail  30 . 
     FIG. 5A  is another side view of the tool of  FIG. 4  after the tool  100  has been lowered and the tool  100  is moving in the direction of arrow M 1  and is inserting the bumper strip  40  into the gunnel rail  30 . After installation, the raised tip edge portion  46  of the bumper insert  40  remains exposed above the gunnel rail  30 . The inclined bottom faces  163 (only one is shown) of the guide posts  162  of the guide member  160  are short enough to not contact any part of the deck shell  10 . 
     FIG. 5B  is a top view of the tool of  FIG. 5A  along arrow  5 B further showing the bumper strip  40  having been inserted into the gunnel rail  30 . The hands of the installer have been removed for showing clarity. Here it is clear that the longitudinal body  194  of the tool base  190  while being inclined remains in an overlapping arrangement that is not off-angle in relation to the longitudinal direction of the gunnel rail  30 . Unlike prior art devices previously described, tool  100  does not deviate side to side while installing the bumper insert strips  40 . Referring to both  FIGS. 5A and 5B , the user gripping the tool  100  maintains their hands  50 ,  60  in a consistent parallel position in relation to the gunnel rail  30  as the tool is moving in the direction of arrow M 1  over the gunnel rail  30 . 
     FIG. 5C  is a trailing end view of the tool  100  of  FIG. 5A  along arrows  5 C inserting the strip  40  into the gunnel rail  30 . As the bumper strip  40  is being inserted, the raised tip edge portion  46  of the bumper insert  40  while being extruded out from the tool  100  can continuously keep this portion of the tool  100 (such as the wheels  125 ,  127 , and guide track  170 ) from physically contacting the gunnel rail  30  directly, thus eliminating any scratches and scrapes that can damage the gunnel rail  30 , that often can occur with prior art methods and devices previously described. 
     FIG. 5D  is a leading end view of the tool  100  of  FIG. 5A  along arrows  5 D inserting the strip into the gunnel rail  30 . Here, the interior roof portion  165  and inwardly curved upper inside wall surfaces  161  of the guide posts  162 ,  166  can rest on and can hug against the upper exterior portions of inwardly bending lip portions  32 ,  34  of gunnel rail base  30 . As previously described using a plastic type guide member  30  would allow for the guide posts  162 ,  166  to slide over the gunnel rail lip portions  32 ,  34 . Furthermore, using short posts  162 ,  166  with bottom inclined faces  163 ,  167  that do not have to directly contact any other surface  10  of the boat, reduces any damage to the boat surface  10  that can occur with the prior art methods and devices previously described. 
   Referring to  FIGS. 2E ,  3 A,  3 B, and  5 A- 5 D, the guide member  160  can have an interior roof portion  165  along inwardly curving side walls  161  which together can be sized to conform about the exterior curved surfaces of the upper lip portion  32  and lower lip portion  34  of gunnel rail base  30  so that the guide member  160  with posts  162 ,  166  is raised above deck hull  10 . The grooved out indentation of roof portion  165  and inwardly curved walls  161 , formed between posts  162 ,  166  can have a continuous inclined angle A 2  of approximately 10 to approximately 45 degrees, so that the roof portion  165  and inwardly curved walls  161  keep the guide member  160  and tool  100  at a continuous inclined angle of A 1 /A 2 . The posts  162  and  166  wrapping down along the upper sides of upper lip portion  32  and lower lip portion  34  of the gunnel rail base  30  can prevent the tool  100  from moving side to side as it travels over the gunnel rail base  30 . 
   The subject invention can allow an installer to merely support the weight of the tool  100  when the strip insert material  40  is being automatically inserted by the motorized wheels into the gunnel rail base  30 , since the guide member  130  can help fix a consistent selected inclined angle for the tool  100 , and the guide member posts  162 ,  166  can help keep the tool  100  from easily shifting side to side when being used. The longitudinal handle portion  194  of the tool can be maintained to substantially overlap the longitudinal length of the rail base  30 , with the user&#39;s hands  50 ,  60  consistently moving substantially parallel to the moving direction M 1  of the tool  100 (FIG.  5 A). 
     FIG. 6A  is a perspective bottom view of a second preferred embodiment automatic multipurpose tool  200 .  FIG. 6B  is a perspective top view of the tool  200  of  FIG. 6A  along arrow  6 B.  FIG. 7  is an exploded bottom perspective view of the tool  200  of  FIGS. 6A-6B  with chuck head portion  205  detached from tool base  290  with interior components visible. 
   Referring to  FIGS. 6A ,  6 B and  7 , the second embodiment  200  shows a fixed type automatic multi-purpose tool  200  where the tool base portion  290  is generally not intended to be removed from the head portion  205 . Here the anti-rotation bracket  240  is similar to the anti-rotation bracket  240  of the previous embodiment except that a bottom wall portion  249  is included which restricts the head portion  205  from being easily detachable from the tool base portion  190 , and a locking fastener  241  such as a screw, and the like, can further fixably attach the head portion  205  to the tool base portion  290 . The remaining components shown such as handle  250 , guide member  260 , and wheels  213 ,  217 ,  219 ,  225 ,  227  correspond to similar arranged components in the first embodiment. The second embodiment functions and operates in an identical manner to that of the first embodiment when being used.
