Without limiting the scope of the invention, its background is described in connection with tools and kits for paintless dent removal. More particularly, the invention describes a universal handle configured for attachment to a variety of tools with an option of rapid exchange of the tools when necessary. A kit containing the universal handle and a series of attachments suitable for paintless dent removal is also described.
Paintless dent removal tools are well known in the art and are effective means for removing dents from the body of a vehicle. Common paintless dent removal tools include rods of various shapes and lengths, wire tools, hook tools, hand tools, hammers, and whale tails. Although effective in most applications, conventional paintless dent removal tools have limitations. For example, a conventional tool is typically made with a manual handle which limits its use in certain working positions. One solution to increase a tool's versatility has been to remove the manual handle from a conventional paintless dent removal tool and place a ratcheting handle in its place. This, however, forces a user to constantly adjust and reposition the tool, thereby increasing user fatigue and discomfort.
The need exists therefore for a universal dent removal tool and a set of dent removal tips that can be easily attached and removed from the handle of the tool so as to expedite the speed of the dent removal process and reduce the physical efforts needed to perform such repair.
Accordingly, it is an object of the present invention to overcome these and other drawbacks of the prior art by providing a novel universal dent removal tool and corresponding attachment tips to facilitate rapid tool exchange during paintless dent removal.
It is another object of the present invention to provide a kit containing a universal dent removal tool with a handle and a variety of dent removal tips that can be removably attached to the handle in rapid succession.
It is a further object of the present invention to provide a novel dent removal tool allowing simple repositioning of the handle during the process of manipulating the dent removal tip in order to remove a dent without disturbing the existing paint layer.
It is yet another object of the invention to provide a kit for paintless dent removal having quick-connect couplings to make use of a plurality of other commercially available dent removal tools.
The novel dent removal tool features a tool head assembly with a handle extending therefrom in both directions. The tool head assembly includes a housing containing a toothed wheel and allowing the wheel to rotate inside the housing. The toothed wheel has an outer rim and a plurality of teeth extending outwards therefrom. The inner rim of the toothed wheel is configured to receive, replace, and removably retain any one of a plurality of sockets provided with the tool as a kit.
Each of the plurality of sockets may be attached to one of a corresponding plurality of dent removal tips, which come in various shapes necessary to achieve a complete repair of the dent.
A spring-loaded teethed lever is provided in the housing and is configured to be movable between a first released position and a second depressed position by pushing onto or releasing a first button attached thereto. When the teethed lever is in the first “released” position, the teethed lever is normally engaged with the plurality of teeth of the toothed wheel, thereby preventing the wheel from rotation in any direction.
Depressing the first button moves the teethed lever into a second “depressed” position, which disengages thereof from the plurality of teeth of the toothed wheel and allows the wheel to rotate in either direction. This makes it possible to freely rotate and adjust the position of the handle in relation to the dent removal tip.
Releasing the first button returns the teethed lever to be engaged with the toothed wheel once again—restoring the secure and fixed relationship between the handle and the tip of the dent removal tool such that the repair process may be resumed.
The present invention further features one or more quick-connect couplings to make use of commercially available dent removal tools, thereby making it convenient for owners of these tools to use them with the handle of the present invention.
Subject matter is particularly pointed out and distinctly claimed in the concluding portion of the specification. The foregoing and other features of the present disclosure will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the disclosure and are, therefore, not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through the use of the accompanying drawings, in which:
The following description sets forth various examples along with specific details to provide a thorough understanding of claimed subject matter. It will be understood by those skilled in the art, however, that claimed subject matter may be practiced without one or more of the specific details disclosed herein. Further, in some circumstances, well-known methods, procedures, systems, components and/or circuits have not been described in detail in order to avoid unnecessarily obscuring claimed subject matter. In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
Various types of dent repair tools have been used in automobile body repair for removing dents from body panels. Some of these devices require that holes be drilled in the body panel in order to attach the dent puller to the damaged area of the panel. Other devices are designed to remove small dents without causing further damage to the body panel. Use of these latter devices generally does not require repainting of the panel, and is thus referred to as “paintless” dent repair.
Some of the maneuvers with the handle require the handle to be fixed in relationship to the tip 10 so that turning and tilting the handle causes the tip 10 to impart a desired effect on the repair area. Access to the repair area may be limited in some circumstances and tool repositioning is frequently needed. To reposition the tool or just to turn and reposition the handle without shifting the position of the tip itself, the user needs a convenient way to allow rotation of the handle around the longitudinal axis of the tip 10. Rapid engagement and disengagement of the handle assembly 100 and the tip 10 as well as rapid exchange of one tip to another is advantageous in expediting the work of the user in removing the dent.
A typical kit may include several tips 10, all of which may feature a central shaft with a tip extending therefrom, One end of the shaft may have a standard coupler to the handle, such as a KIPP attachment, featured on all tool tips of the kit and allowing the user to utilize the same handle assembly with a variety of tips. Other than KIPP conventions for coupling of the tip to the handle may also be used as the invention is not limited in this regard.
The connector 40 may be pushed into the tool head assembly until it engages with thereof. Release of the connector 40 and the corresponding tool tip 10 may be accomplished by pushing on the second button 70 as described in greater detail below.
A broad illustration of the tool head and handle assembly 100 is seen in
Details of the tool head assembly 30 are now described in greater detail with reference to
A general side view of the back of the tool head assembly 30 is seen in
One key component of the tool head assembly is a teethed wheel 50, best seen in
The toothed wheel assembly is seen as an individual component in
The same view of the back of the tool head assembly 30 is seen in
Another view of that subassembly is seen in
The use of the device is now described in greater detail. Initially, the connector 40 is not present and the clips 74 are located in close proximity to each other inside the void formed in the toothed wheel 50. The teethed lever 62 is engaged with the teeth 52 of the wheel 50 thereby fixing its position inside the housing 32.
The user takes the desired tool tip 10 and inserts the tapered end 42 into the opening in the toothed wheel 50. The taper of the tapered end 42 causes the clips 74 to spread apart. Once the tapered end passed under the clips 74, springs 76 push the clips 74 closer together as they protrude inside the neck 43 of the connector 40. This motion causes engagement of the connector 40 with the tool head assembly 30 in a fixed position so that the user may use the handle to manipulate the end of the tool as required for the dent removal repair.
If an exchange of one tool tip for another is needed, the user presses the second button 70. That in turn causes the release pin 72 to move deeper inside the internal opening of the toothed wheel 50. Bars 73 engage with the clips 74 and cause their lateral movement apart from each other. This releases the tapered end 42 and the user may remove the tool tip 10 from the handle assembly 100, followed by insertion of another tool tip 10 using reverse series of steps.
If a repositioning or rotation of the handle is needed without a need to change the tool tip 10, the user presses on the first spring-loaded button 60, which causes disengagement of the teethed lever 62 from the plurality of teeth 52 of the toothed wheel 50. Once the lever 62 is disengaged, the toothed wheel 50 is free to rotate in any direction so that the user may reposition the handle of the tool in any way that is convenient. Release of the button 60 causes the teethed lever 62 to move back into a position of engagement with the teeth 52 of the wheel 50, thereby securely and fixedly retaining the dent removal tip to facilitate direct transmission of force and torque from the handle assembly 100 to the dent removal tip 10 during dent removal operations.
All components of the novel device may be made from metal or from other suitable materials. Handle portions 20, for example, may be made from a suitable polymer to reduce the overall weight of the tool.
The above-described first embodiment provides for the main use of the invention, namely the novel handle. It does have one limitation for the owners of existing commercially-available tips 10, in that each tip 10 has to be fitted with a corresponding bushing 13 to transition to the connector 40. For each tip 10, the owner of the tip would have to buy and permanently attach a corresponding bushing 13 with the dedicated connector 40.
The second and the third embodiments of the invention address this limitation by providing a quick-connect coupling 213 and 313 configured to work with the most popular commercially available tips 10. Using the quick-connect coupling allows the tool owner to attach the coupling to the handle once and then rapidly replace tips 10 during the repair process.
The quick-connect body 220, in turn, features a handle side 222 and a tool side 224 on the opposite side of the quick-connect body 220. The handle side 222 has one, two, or more spring seats 226 (two are illustrated in these figures) protruding outwards from the body 220 and configured to each have a cavity in which one end of the spring 260 may be placed. A plurality of spring seats 226 may be symmetrically located around the periphery of the quick-connect body 220 as the invention is not limited in this regard. Alternatively, other spring arrangements may be used, such as a singular circular spring positioned between the slider 230 and the handle side 222.
The tool side 224 of the quick-connect body 220 may be threaded and sized to accept the internally threaded cap 240 outside thereof. The internal diameter of the tool side 224 may be selected to accept inside the circular end 12 of the tip 10. A toothed opening 228 may be positioned in the middle portion of the quick-connect body 220, as better seen in
One, two, or more fixating balls 250 may be positioned about the periphery of the quick-connect body 220.
The spring-loaded slider 230 in combination with the two fixating balls 250 are seen in greater detail in
Each fixating ball 250 is placed inside a tapered groove 238 having an inclination angle oriented away from the tool side 224. Each groove 238 is shaped to urge the fixating ball into the corresponding opening in the quick-connect body 220 when the slider 230 is released—so as to lock the tool tip 10 in place inside the quick-connect coupling 213. At the same time, each groove 238 is also shaped to release the fixating ball and have sufficient space for the fixating ball 250 to move out of the groove 14 of the tool tip 10 when the slider 230 is moved towards the handles 20 and when the springs 260 are compressed.
The cap 240 is designed to retain the slider 230 over the quick-connect body 220. It has a threaded inner diameter and a threaded opening 242 for a set screw, which may extend into the corresponding opening 223 of the body 220 so as to retain the cap 240 in place.
The entire design of the quick-connect coupling 213 is made with smooth corners and no sharp edges so as to improve the safety of operation and avoid slips and cuts that may be caused during the forceful application of the paintless dent removal procedures.
In use, the quick-connect coupling 213 is first assembled with the connector 40 by inserting the first end 41 thereof into the corresponding opening of the handle side 222 and fixating it therein by a set screw placed into the threaded hole 225 of the handle side 222. The second end of the connector 40 is then inserted into the tool head assembly 30. Pushing on both slider handles 232 and 234 in a direction towards the tool head assembly 30 causes the springs 260 to compress, allowing the slider 230 to move to the release position, thereby allowing the fixating balls 250 to move outwards. A socket of the tool tip 10 is then inserted into the tool side 224 of the quick-connect body 220 until the toothed circular end 12 mates with the corresponding opening 228. Releasing the slider 230 causes the springs 260 to urge the slider 230 to move in the direction towards the tip 10, which causes the tapered grooves 238 to push on the fixating balls 250 and move them towards the center of the quick-connect body 220. At this point, the fixating balls 250 are located within the space defined by the groove 14 of the tool tip 10, thereby fixating the position of the tool tip 10 inside the quick-coupling 213 and the head assembly 30. The use of the entire combination of the head assembly 30, quick-connect coupling 213, and the tip 10 may now begin for the purposes of dent removal repair.
Once the tip 10 needs to be changed to another tip 10 with the same KIPP attachment, it can be accomplished by pulling the slider 230 again towards the tool head assembly 30, thereby allowing the fixating balls 250 to move outwards and releasing the previous tool from the quick-connect coupling 213. Positioning the next tool tip 10 inside the coupling 213 and releasing the handles 232 and 234 accomplishes firm fixation of the next tool tip in the tool head assembly, which facilitates the continuation of the repair process.
The design of the quick-connect coupling is advantageous in that it is symmetrical and provides for a longitudinal alignment of the dent removal tip with a center of the housing, thereby balancing the handles to be equally positioned on both sides of the dent removal tip, which makes the use of the handles 20 intuitive and natural.
A third embodiment of the invention is illustrated in
Further configurations of the quick-connect coupling are also envisioned and may be shaped to match the shape of other commercially-available tools in this field. Using the quick-connect coupling that is attached to the tool head assembly 30 makes the entire tool kit contain two quick-connect devices so as to make it convenient to use a broad variety of tools designed for paintless dent removal.
The tool kit, in this case, may comprise the tool head assembly 30 with the handles 20 put together with at least one or more quick-connect couplings to make the tool compatible with the tips 10 available commercially elsewhere.
