The invention relates generally to the field of mechanical apparatuses, and more particularly, to a tattoo machine with a floating collet apparatus and system configured to accept multiple tattoo machine grip styles.
Tattoo machines generally use electric coils to drive a spring-loaded reciprocating needle structure in order to etch skin. This type of tattoo etching machine is heavy and cumbersome for the operator (the tattoo artist), is prone to overheating, and is inherently noisy during operation. Due to the nature of the prior designs, with exposed coils and electrical connections, it has not been possible to properly clean, much less sterilize or autoclave, the tattoo machine itself. This creates an inherent health and safety issue for the customer as well as for the artist.
Some solutions in the art have attempted to address the problem addressed above by separating the grip portion, which accepts the reciprocating needle, from the machine portion, which converts electrical energy into a reciprocating motion. However, this falls short in that many grip manufacturers create specific grip-machine interfaces that make it necessary to use their grip-machine combination. Tattoo machine users, being artists, prefer to have the flexibility to use various needle-grip-machine combinations in much the same way a painter utilizes different brushes.
Other solutions in this area are deficient in that: the components susceptible to be in contact with human fluids cannot be properly sterilized; the stroke of the reciprocating needle is not adjustable; the reciprocating needle driver has no give; the machines are not cross-compatible with other needle, grip, and cartridge systems; and the machines are cumbersome, noisy, and heavy.
It would, therefore, be desirable to have a tattoo machine with adjustable stroke, that is compatible with multiple tattoo needle cartridge systems and grip styles, with a self-aligning and sterilizable drive bar that has adjustable give, and is lightweight and virtually vibration free.
While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, Applicant in no way disclaims these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein.
In this specification where a document, act, or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act, or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge, or otherwise constitutes prior art under the applicable statutory provision; or is known to be relevant to an attempt to solve any problem with which this specification is concerned.
A preferred embodiment of the present invention is directed to a tattoo machine floating collet apparatus. The apparatus comprises a vise receiver, a vise receiver knob, and a vise collet. In this embodiment, the components of the apparatus are configured to accept a tattoo machine grip backstem. The components are arranged so that the vise collet is captured between the vise receiver and the vise knob. In use, the backstem portion of a tattoo machine grip is inserted into the vise receiver through the vise knob and vise collet. As the vise knob is tighten down onto the vise receiver, the vise collet tightens down on the backstem of the tattoo machine grip and holds it in place.
Another embodiment of the present invention is directed to an apparatus that satisfies the need for a tattoo machine that is designed to be compatible with multiple grips and grip styles. This embodiment comprises a drive bar, a dampener, a slider, a stroke module, a vise receiver, and a housing.
Further embodiments may also comprise a vise receiver collet and knob, a removable motor assembly, and adjustable stroke module stroke distance.
Yet another embodiment may comprise a collet vise system for accepting tattoo machine cartridge grips. Embodiments of such a system may comprise a tattoo machine apparatus, a collet apparatus, and a vise knob apparatus.
Certain embodiments of the present invention may be used for, but not limited to, the etching of human skin for tattooing. It is contemplated, however, that the use of certain embodiments of the present invention in other applications beyond traditional tattoo use, is within the scope of the present invention. For example, the invention may be used for cosmetic tattooing, use in applications other than on humans, or for other medical or industrial uses.
Embodiments of the present invention may include components manufactured from various materials based upon the contemplated use. For embodiments that are contemplated for human use, materials that are durable, autoclaveable, and sanitary are contemplated to be within the scope of the present invention. By way of example and not limitation, materials may be stainless steel, anodized aluminum, or polycarbonates.
The present invention may address one or more of the problems and deficiencies of the prior art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
In the Summary above, in the Description and appended Claims below, and in the accompanying drawings, reference is made to particular features of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and in the invention generally.
The term “comprises” and grammatical equivalents thereof are used herein to mean that other components, structures, steps, etc. are optionally present. For example, an article “comprising” (or “which comprises”) components A, B, and C can consist of (i.e., contain only) components A, B, and C, or van contain not only components A, B, and C, but also one or more other components or structures.
The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example, “at least 1” means 1 more than 1. The term “at most” followed by a number is used herein to denote the end of a range ending with that number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4, and “at most 40% means 40% or less than 40%. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number)-(a second number),” this means a range whose lower limit is the first number and whose upper limit is the second number. For example, 25 to 100 mm means a range whose lower limit is 25 mm, and whose upper limit is 100 mm.
The term “mechanical features” is used herein to mean features of a component, mechanical or geometric, which have a functional purpose of attaching or linking that component to one or more other components with compatible or corresponding mechanical features. An example of a mechanical feature is a slot in a component, where said slot is designed to accept a tab from another component and the union of the slot and tab from the two components effectively links, attaches, fixes, and/or locks the components together. The term “mechanical features” refers to, but is not limited to: hooks, hook and loop fasteners, slot and tabs, all male and female fasteners, screws, bolts, nuts, holes that have been tapped, latches, pins, etc.
While the specification will conclude with claims defining the features of embodiments of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the figures, in which like reference numerals are carried forward.

Tattoo Machine Floating Vise Collet Apparatus Embodiment 1000
Referring to the figures in general, and to
The drive bar 110 is a push rod that mechanically couples the motion from an attached motor or drive mechanism with an attached needle mechanism in order to translate the motor's motion into the needle's reciprocating motion. The drive bar 110 has a first end, a distal second end, and a body defining a central longitudinal axis extending between the first end and the second end. The drive bar 110 is made of a sufficiently rigid material to not buckle under ordinary loads. Materials that are easily sterilized and antimicrobial are preferred.
The dampener 120 is a compressible component capable of absorbing, partially absorbing, or completely translating an applied longitudinal load. Embodiments of the dampener 120 may be accomplished using a coil spring, a compressible closed cell foam, or other material or assembly of materials that are capable of performing the function of absorbing, partially absorbing, or completely translating a longitudinal load.
The slider 130 couples the stroke module 140 to the dampener 120, which is coupled to the drive bar 110. The slider 130 has a body portion with a central longitudinal axis, a first end, and a second end, where a section of the body portion at the second end has a first bearing surface, a section of the body portion at the first end has a blind bore coaxial with the central longitudinal axis extending from the first end into the body portion but not completely through the body portion so that the blind bore forms an opening in the body portion with a substantially cylindrical wall and a second bearing surface orthogonal to the central longitudinal axis and distal from the body portion first end, and the first bearing surface is in contact with the dampener 120 second surface. Although it is contemplated that the slider may be manufactured from various materials, a preferred embodiment of the present invention comprises a slider that is made of an acetal resin containing PTFE that will reduce friction and ensure the overall smooth operation and low vibration of the apparatus.
The stroke module 140 couples a motor to the slider 130. The stroke module has a cam portion and a receptacle portion. The receptacle portion is configured to be operably communicative with a motor such that motion from the motor is translated through the receptacle portion to the cam portion. In other words, as the receptacle portion is caused to rotate due to a motor, the cam portion likewise rotates. The stroke module 140 is assembled in relation to the slider 130 so that the cam is slidingly communicative with the slider first bearing surface.
The vise receiver 150 is configured to receive a tattoo needle cartridge. The vise receiver has a first end, a second end, and a body wall defining a one or more inner surface and a one or more outer surface extending between the first end and second end that has a central axis and varying cross-section, where the first end has an externally threaded portion and the second end is configured to receive the slider first end, at least a portion of the slider body. The vise receiver is further configured to allow the drive bar first end and at least a portion of the drive bar body to extend through the vise receiver and past the vise receiver first end. The vise receiver acts to constrain the slider to move only longitudinally along its central axis. The vise receiver further acts to accept standard screw-on adjustable grips.
The various components are constrained in relation to each other by a machine housing 160. The machine housing 160 has a first opening, a second opening, and a body. The first opening is configured to fixedly attach and constrain the vise receiver in translational and rotational relation to the machine housing. The second opening is configured to fixedly attach and constrain the stroke module in translational and rotational relation to the machine housing, but allowing the cam portion and receptacle portion of the stroke module to operate freely. The machine housing is further configured to maintain operable communication between the stroke module, the slider, and the vise receiver.
In this way, rotational motion of the receptacle portion is translated into rotational motion of the cam portion. The rotational motion of the cam portion is translated into longitudinal motion of the slider. Since the slider is longitudinally communicative with the drive bar, via the damper, the rotational motion of the receptacle portion is translated into reciprocating longitudinal motion of the drive bar. Furthermore, the second end of the drive bar is mechanically coupled to the dampener 120 such that it is free to pivot in relation to the central axis, but still reciprocate back and forth. This may be accomplished, for example, by making the drive bar second end terminate in a sphere. In this way, the pivoting drive bar self-aligns with the plungers of an attached needle cartridge, thus ensuring perfect rectilinear motion.
Variations on this embodiment are contemplated to be within the scope of the invention. For example, the dampener and the slider may be eliminated so that the drive bar is connected directly to the stroke module.
Other embodiments of the present invention may also comprise a vise receiver collet 170 and a vise receiver knob 180. In such an embodiment, the vise receiver collet is coaxially inserted into the vise receiver first end and the vise receiver knob is threaded onto the external threads of the vise receiver first end such that, as the vise receiver knob is rotated so as to tighten the vise receiver knob onto the vise receiver, the vise receiver knob pushes the vise receiver collet further into the vise receiver first end, thereby reducing the inner diameter of the vise receiver collet. In this way, the apparatus may be compatible with back stem style adjustable grips. In order to insert a standard back stem style grip, partially unscrew the vise receiver knob enough to loosen it but not fully remove it. Gently guide the back stem of the grip over the drive bar and insert it into the opening of the vise receiver knob, passing through the opening of the vise receiver collet. Once the back stem of the grip is inserted the desired distance, tighten the vise receiver knob in order to secure the grip in place. Embodiments of the invention contemplate the presence of ridges, or other protrusions, on the inside surface of the vise receiver collet, that are configured to interface with grooves in the back stem of a grip so as to counter or resist against any rotation of the back stem tube in the vise receiver collet.
Another embodiment of the present invention may further comprise a motor assembly. The motor assembly is comprised of a motor, an electrical connector, and a housing. The housing protects and encases the motor body, but allows the motor shaft and electrical connector to protrude from the housing. The motor assembly housing further has mechanical features that allow it to be removably attached to the machine housing second opening ensuring that the motor shaft and the stroke module receptacle portion are operatively communicative.
Yet another embodiment of the present invention may further comprise a stroke module where the stroke distance, the longitudinal displacement of the cam portion, is adjustable.
Yet another embodiment of the present invention may further comprise a dampener where the dampener resistance is adjustable. By way of illustration and not limitation,
Yet another embodiment of the present invention contemplates a two-part drive bar, where the drive bar body is separable by mechanical means into a first portion where the first end is removable from the system, and a second portion where the second end remains operably connected to the system. This two-part drive bar system allows for the portion of the drive bar that is in communication with the needle cartridge to be removed for sterilization. Additionally, this two-part drive bar allows for the ability to interchange the configuration of the drive bar first end in order to suit the requirements of a variety of grip styles.
An embodiment of the present invention in the form of a collet vise system for accepting tattoo machine cartridge grips comprises a tattoo machine apparatus, a collet apparatus, and a vise knob apparatus.
In this system embodiment, the tattoo machine apparatus has an externally threaded vise receiver, where said externally threaded vise receiver is substantially cylindrical with an internal bore having an internal bore diameter, and is configured to accept a screw-on style adjustable cartridge grip with internal threading.
The collet apparatus has a substantially conical outer surface with a central axis, an adjustable outer surface major diameter configured to be larger than the internal bore diameter of the tattoo machine apparatus externally threaded vise receiver, an adjustable outer surface minor diameter configured to be smaller than the internal bore diameter of the tattoo machine apparatus externally threaded vise receiver, a substantially cylindrical inner surface coaxial to the central axis of the conical outer surface with an adjustable inner diameter configured to accept a standard back stem style grip tube, a first bearing surface at the outer surface major diameter portion of the apparatus, a second bearing surface at the outer surface minor diameter portion of the apparatus, where the apparatus is coaxially inserted into the internal bore of the tattoo machine apparatus externally threaded vise receiver so that the first bearing surface protrudes outside of the tattoo machine apparatus externally threaded vise receiver.
The vise knob apparatus is substantially cylindrical, with a first end, an outer surface having a one or more grip features, a second end distal to the first end, a central bore extending from the first end to the second end defining an inner surface, where a portion of the inner surface extending inward from the second end is threaded such that the thread is configured to mate with the thread of the tattoo machine apparatus externally threaded vise receiver, and a portion of the inner surface extending inward from the first end has a one or more internal bearing surface configured to contact with the collet apparatus first bearing surface when the inner surface threads are engaged with the tattoo machine apparatus vise receiver external threads.
In light of the foregoing description, it should be recognized that embodiments in accordance with the present invention can be realized in numerous configurations contemplated to be within the scope and spirit of the claims. Additionally, the description above is intended by way of example only and is not intended to limit the present invention in any way, except as set forth in the claims.
