Description:
FIELD OF THE DISCLOSURE 
       [0001]    The present disclosure relates to mobility devices, and, in particular, mobility devices which may be removably mounted on one or more vehicle wheels, preferably on any wheel pair of a single axel, and which may be capable of transforming between a first position and a second position. In the first position, the mobility device may have as little as possible effect on the mobility of the vehicle associated therewith; in a second position, the mobility device may have a considerable effect on the mobility of the vehicle associated therewith; and, the mobility device may be continuously configurable throughout a range of position between the first and the second positions. 
       BACKGROUND 
       [0002]    Generally, simple means for enhancing the mobility, in particular traction, of a vehicle, are well-known. One such means for enhancing traction of the vehicle, particularly over ice and snow covered roads are removable chains (see, as an illustrative, nonbinding example, http://en.wikipedia.org/wiki/Snow_chains, disclosing, inter alia:
   “Snow chains, or tire chains, are devices which are affixed to the tires of vehicles to provide superior traction when driving through snow and ice.   Snow chains are attached to the drive wheels of a vehicle. Chains are usually sold in pairs and must be purchased to match a particular tire size (tire diameter and tread width). Driving with chains will reduce fuel efficiency and can limit the speed of the automobile to approximately 30 mph (50 km/h).   
 
       Deployment 
       [0005]    In snowy conditions, transportation authorities may require snow chains to be fitted upon vehicles. This can apply to all vehicles, or those that lack certain motive combinations such as fourwheel drive and/or specific classifications of tires. Local requirements may be enforced at checkpoints. Snow chains should always be fitted to one or more drive axles of a vehicle, with varying requirements for dualtire or multidrivenaxle vehicles that range from one pair of tires on a driven axle to all tires on all driven axles being required to have snow chains fitted when conditions and/or signage require it.” 
         [0006]    Further, the above cited reference teaches: 
       Common Chain Failures 
       [0000]    
       
         
           
             Driving too fast with chains. Maximum speed recommended in the chain&#39;s owner&#39;s manual is generally 30 to 50 km/h (2030 mph). 
             Driving on dry roads with chains for extended periods of time. 
             Not securing the chains tightly enough. Manuals recommend that the chains be tightened a second time after driving a short distance, and to check for tightness from time to time. Chains that come loose should be refastened or removed before they wrap around the vehicle&#39;s drive axle. 
             Tensioners or adjusters may be required. (Some tire chains do not require tensioners and may be damaged if tensioners are used.)

       Legality of Use 
       [0021]    Laws vary considerably concerning the legality of the use of snow chains. Some jurisdictions may require their use in certain weather conditions or during certain months of the year, while other states or jurisdictions may ban their use altogether to preserve the surface of the roads. 
         [0022]    Alternatives to snow chains are also known in the art. One such illustrative example may be seen in U.S. Pat. No. 2,765,199, illustrated here on  FIGS. 9 and 10  (Prior-art 1), and disclosing, inter alia, “This invention relates generally to vehicle wheel assemblies and is more particularly concerned with a novel antiskid wheel assembly wherein the vehicle upon which the novel assemblies are mounted is readily usable in snow, mud, etc. A primary object of the invention is to provide a novel antiskid wheel assembly including a wheel having a rim supporting thereon a tire assembly; a plurality of radially disposed antiskid lug assemblies reciprocably supported on the wheel rim, the lug assemblies including a friction increasing means on a terminal end portion thereof which may be extended beyond the outer periphery of the tire assembly, and fluid pressure means supported on the wheel and engageable with the lug assemblies effective to overcome spring means associated with the lug assemblies which normally urge the lug assemblies to a retracted position below the outer periphery of the tire assemblies. 
         [0023]    “A further object of the invention in conformance with that set forth is to provide in a novel antiskid wheel assembly of the character set forth a fluid pressure means comprising an annular inflatable or collapsible tube which is concentrically disposed within the inner periphery of the wheel rim of the novel wheel assembly, wherein the lug assemblies comprise a plurality of radially disposed support sleeves extending through the rim, said support sleeves reciprocably supporting a support shaft having on one end a friction increasing means extendable beyond the outer periphery of the tire assembly, the other end of said shaft being engageable by the annular force transmitting inflatable tube, said shafts having circumposed about an intermediate portion thereof a compression spring which engages the inner periphery of the wheel rim and a terminal abutment portion on the inner end of the support shaft.” 
         [0024]    Another alternative is shown by U.S. Pat. No. 5,788,335, illustrated here as  FIGS. 11 and 12  (Prior-Art 2) and disclosing, inter alia, “As shown in  FIG. 3 , the rim  22  of the traction device  10  is sandwiched between the rims  13  of the inner wheel  14  and outer wheel  12 . The rim  13  of the wheels  12 ,  14  and the rim  22  of the traction device  10  are mounted to the wheel assembly  16  and are secured by the mounting lugs or bolts  15 . The traction device  10  is thus rotatable with the wheels  12 ,  14 . The valve stem  28  extends through a conventional opening provided in the rim  13  of the wheels  12 . This provides access to the valve stem  28  for inflating and deflating the tire  24  of the traction device  10 . As shown in the figure, the tire  24  of the traction device  10  is illustrated in the deflated state (contracted) in solid lines and the tire  24  is shown in the inflated (expanded) state in dashed lines. In the contracted state, the tire  24  has been deflated to contract radially inward and thus the diameter of the tire  24  is less than the diameter of the wheels  12 ,  14 . In the expanded state the tire  24  has been inflated with pressurized air to expand the tire radially to exceed the diameter of the wheels  12 ,  14 . 
         [0025]    “The illustration of the tire  24  in the expanded state is exaggerated for illustrative purposes. The tire  24  is expanded such that the studs  20  will extend beyond the diameter of the wheels  12 ,  14  to engage the supporting surface (roadway). The wheels  12 ,  14  still supports the vehicle weight and the tire  24  provides the traction. 
         [0026]    “Referring to the dashed outline of the tire  24  of the traction device  10  of  FIGS. 3 and 4  (which shows the traction device  10  in the expanded state) the tire  24  has been inflated by pressurized air. The tire  24  has expanded radially such that the diameter of the tire  24  is greater than the wheels  12 ,  14 . The studs  20 , when the tire  24  is in the expanded state, will extend beyond the diameter of the wheels  12 ,  14  to engage the roadway R projected through an ice or snow covering S. The studs  20  in engagement with the roadway R will provide the necessary traction required when the vehicle encounters slippery surfaces caused by ice, snow and the like. (The representation of ice/snow covering S and the projection of the studs to the roadway R is illustrative only of the expandability function of the invention and is not intended to accurately depict the manner by which gripping occurs, e.g., the studs in packed snow or ice conditions will not necessarily penetrate through to the bare roadway.)” 
         [0027]    It would be desirable to have a mobility device which may be configurable, and may generally designed to be removably mounted on one or more vehicle wheels, and which may be capable of transforming between a position where the mobility enhancing device may have as little as possible impact on a mobility of the vehicle, and a second position, wherein the mobility device may have a considerable impact on the mobility of the vehicle associated therewith. This may be attained with the subject matter in accordance with the claims.

     DETAILED DESCRIPTION 
       [0041]    Attention is presently drawn to the figures.  FIGS. 1 and 2  show an outer and an inner perspective view, respectively, of a mobility device  100 . The term “outer” generally relates to a direction away from, while “inner” generally relates to a direction towards, a body (not shown) of a vehicle (not shown). The mobility device  100  has a generally cylindrically shaped device body  102  extending to an external radius R about a longitudinal axis L extending along a wheel axis. Parallel circular outer base  110  and an inner base  120  define a height H extending therebetween along the longitudinal axis L. 
         [0042]    Attention is further directed to  FIGS. 3 and 4 . The height H may be considerably shorter than the external radius R of the device body  102 , which further comprises a generally cylindrical apron  130  having a generally radially inwardly facing inside periphery  132  and an opposing, generally radially outwardly facing outside periphery  134 . The outer base  110  comprises a cover  140 , while the inner base  120 , together with the apron  130  which may be integrally formed and/or removably assembled therewith, define a cup  150 . The cup  150  and the cover  140  comprise a casing  155  which may accommodate a mechanism  160 . 
         [0043]    Attention is presently directed to  FIG. 6 . The mechanism  160  comprises a scroll plate  170  extending generally radially, parallel to outer base  110  and the inner base  120  and disposed generally therebetween. The scroll plate  170  comprises an inner plate face  210  and an outer plate face  215  extending generally parallel thereto. The mechanism  160  further comprises a plurality of stakes  180 . The mechanism  160  allows the plurality of stakes  180  to retract so that when retracted a significant portion of a stake extent E S  may be accommodated within the device body  102 . 
         [0044]    The scroll plate  170  extends generally radially outwardly from a plate center  240  to a plate periphery  260 . The scroll plate  170  may comprise at least one spiral groove  200  formed on the scroll plate  170 , sunken axially away from the inner plate face  210  thereof. The at least one spiral groove  200  may be continuous, extending from a groove start  230  adjacent the plate center  240  and spiraling out, or progressing generally radially outwardly as the at least one spiral groove  200  advances generally tangentially, to a groove end  250  adjacent the plate periphery  260 , to define a spiral-out direction S OD  of a rotation of the scroll plate  170 . The spiral groove  200  may comprise a plurality of groove wraps  202 , of which there may comprise a generally centrally disposed, inner wrap  204  and a peripherally outwardly disposed outer groove wrap  206 . 
         [0045]    The at least one spiral groove  200  may be closed, for example by a first wall  270  adjacent a first end  280  and by a second wall  290  adjacent a second end thereof. The first wall  280  and the second wall  290  may extend generally transversely away from a groove floor  300  to the inner plate face  210 . Generally, the at least one spiral groove  200  dips below the inner plate face  210 , but optionally may not penetrate through the spiral plate to open onto the outer plate face  215 . Potentially, the at least one spiral groove  200  may be further bounded by a curved inner flank  310  facing generally radially peripherally and by a curved outer flank  320  facing generally radially centrally. Optionally, the inner flank  310  and the outer flank  320  define a gap  330  therebetween. Possibly, there may be formed on the scroll plate  170  a plurality of spiral grooves  200 . In such a case, the plurality of spiral grooves may nest therebetween. 
         [0046]    Attention is presently directed to  FIG. 5 . Each of the plurality of stakes  180  comprises a stake body  340  extending generally radially outwardly to the stake extent E s  from a stake start  182  to a stake end  185  through a stake middle portion  350 . A stake peripheral portion  360  extends from the stake start  182  to the stake end  185 . The stake body  340  further extends generally radially inwardly away from the stake end  185 , along the stake middle portion  350  to the stake central portion  380  terminating in a stake root  385  adjacent the plate center  240 . 
         [0047]    Optionally, the stake end  185  may comprise the stake shoe  190 . The stake body  340  may be generally manufactured from any known or discovered tough, strong, and/or rigid yet durable composition, including as an illustrative example only, but not limited to, known and/or discovered type and/or alloy of steel, aluminum, titanium, and/or composites such as, but not limited to, carbon-fiber composites and/or other similar compositions. The optional stake shoe  190  may be manufactured of any known or discovered resilient and/or tough and/or durable material, including as an illustrative example only, but not limited to, any rubber or synthetic material and/or hard and tough compounds (such as, but not limited to, carbides, ceramics, ceramic-metallic compositions, metal-matrix composites, and/or alloys). The optional stake shoe  190  may be detachably associated with the stake end  185  of the stake body  340  to facilitate replacement thereof. 
         [0048]    The stake central portion  380  may comprise an upstanding pin  390  protruding axially outwardly away from the stake body  340 . Location of each of the pins  390  on its associated one of the plurality of stakes  180  may vary along the stake extent E s . The pin  390  associated with each of the plurality of stakes  180  may extend axially away from the stake body  340 . The pin  390  may slidingly fit within the gap  330  of the spiral groove  200 . Optionally, the pin  390  may be detachably secured to the stake body  340 , to facilitate adjustment. 
         [0049]    Attention is presently drawn to  FIG. 7 . The plurality of stakes  180  may cooperate with the inner base  120 . An outer face  400  of the inner base  120  may comprise a plurality of generally triangular, raised sections  410  extending away from an outer face center  420  to an outer face periphery  430  adjacent the apron  130 . Separating each two adjacent raised sections  410  is a chasm  440  extending generally radially away from the face center  420  towards the apron  130  to terminate in a breach  450  extending through the apron  130 . The breach  450  connects the inside periphery  132  and the outside periphery  134  of the apron  130 . Each one of the chasms  440  is associated with, and accommodates, one of the plurality of stakes  180 . Each one of the plurality of stakes  180  may converge and/or deploy through the associated breach  450 . 
         [0050]    Relating now to  FIGS. 3 to 7 , the scroll plate  170  may be assembled to the mobility device  100  with the at least one spiral groove  200  facing the outer face  400 . Pins  390  of the plurality of stakes  180  may be accommodated by, and distributed along, the at least one spiral groove  200 . Optionally, the pins  390  of a majority of the plurality of stakes  180  may be accommodated by, and distributed about the inner groove wrap  204 . When more than one spiral groove  200  are formed on the scroll plate  170 , different pins  390  associated with different stakes  180  may be accommodated by, and distributed along, different spiral grooves  200 . Optionally, alternating pins  390 , associated with alternating stakes  180 , may be accommodated by, and distributed along, alternating spiral grooves  200 , generally meaning that different but adjacent pins  390  may be accommodated by different, but adjacent, spiral grooves  200 . 
         [0051]    Attention is presently drawn to  FIG. 8 . The mobility device  100  may be generally associated with a vehicle wheel  500 . The wheel  500  may be a single wheel (one wheel mounted upon an end of an axle, not shown) or a dual wheel (two adjacent wheels mounted upon the end of the axle, not shown). With a single wheel, the mobility device  100  may be associated with an outer wheel side  510  (as may be seen on  FIG. 8 ) and/or on an inner wheel side (not shown), and/or two mobility devices  100  may be associated with each of the inner and outer sides of each wheel (not shown). With a dual wheel (see, as illustrative-only, non-limiting examples, U.S. Pat. No. 4,220,372, U.S. Pat. No. 2,132,029), there may be associated one mobility device  100  on either the inner or outer side of the dual wheel (not shown) or between an inner and outer wheel of the dual wheels (not shown). Alternatively, up to three mobility devices may be associated with the dual wheel. 
         [0052]    As an illustrative only, non-limiting in scope and/or spirit example,  FIG. 8 , schematically illustrating the mobility device  100  associated with the outer side opposite an inner side  510  of the vehicle wheel  500 , will be discussed herein below. However, alternatives as disclosed in the paragraph above may be obvious to a person versed in the art. The mobility device  100  may be associated with the wheel  500  by means of an adapter  520  (may be seen on  FIGS. 3 and 4 ). The adapter  520  may removably connects the cup  150  to the outer side  510  of the associated wheel  500 . 
         [0053]    Attention is currently directed to  FIGS. 5 to 12 . When the mobility device  100  is removably mounted on the associated wheel  500 , it is in a first, or converged, state. In the converged state, the plurality of stakes  180  are converged inside the casing  155 , either entirely or leaving a generally radially peripheral zone  365  adjacent the stake end  185  to project generally radially away through the apron  130  and away from the outside periphery  134  of the casing  155 , to a diameter smaller than a wheel external diameter D W . The scroll plate  170  may be rotated in the spiral-out direction S OD , to urge each of the plurality of pins  390  and, with these, each of their respective, associated stakes  180  gradually towards a second, or fully deployed, state. The deployed state may be considered any state of the mobility device  100  in which each of the plurality of stakes projects beyond the wheel external diameter D W . Deployment may vary from a minimal deployment, in which the plurality of stakes  180  may project only partially away or beyond the wheel external diameter D W  to a full extension thereof 
         [0054]    Prior to deployment of the mobility device  100 , at least one adaptor  550  (see  FIGS. 3 and 4 ) may be mounted upon an axle (not shown) on which the associated wheel  500  may be located. Although the particular at least one adaptor  520  is shown as if it may be removably mounted on an outer side opposite the inner side  510 , other embodiments may be removably mounted on the axle (not shown) at an inner side  510 . With dual wheels, as an illustrative, nonbinding example, various embodiments of similar adaptors, as may be obvious to a person versed in the art, may be removably mounted on either the outer side, the inner side, and/or between the dual wheels (not shown). 
         [0055]    When driven on a road not requiring enhanced mobility, the vehicle (not shown) may be driven with only the at least one adapter  550  removably mounted on the associated wheel  500 . With the at least one adaptor  550  mounted on the associated wheel  500 , the vehicle (not shown) may be driven substantially normally. 
         [0056]    Prior to going off-road, particularly where traction requirements may exceed what regular tires may provide, at least one mobility device  100  may be installed upon a corresponding at least one adaptor  550 . Installation may commence with the mobility device  100  in a first, or converged state, wherein the plurality of stakes  180  are accommodated mostly within the casing  155  with most of the stake extent E S  inside the apron  130 , as may be seen in  FIGS. 1 and 2  (albeit without the associated wheel). Installation of the at least one mobility device  100  may be facilitated by the at least one mobility device  100  having a converged diameter smaller than the wheel external diameter D W , so that installation may commence without requiring any lifting facilities, such as, but not limited to, jacks. 
         [0057]    Upon embarking off-road, or when increased traction may be called for, the at least one mobility device may be deployed by extending the plurality of stakes  180  so that at least the stake peripheral portion  360 , terminating in the stake shoe  190 , projects generally radially outwardly beyond the wheel external diameter D W . 
         [0058]    Deployment, or extension of the plurality of stakes  180 , of the mobility device  100 , is facilitated by rotation of the scroll plate  170  relative to the cup  150  in the spiral-out direction S OD  from a converging stance to an extending stance. In the converging stance, the majority of the plurality of stakes  180  may be accommodated by, and distributed about the inner groove wrap  204 , while in the extending stance, optionally a different majority of the plurality of stakes  180  may be accommodated by, and distributed about the outer groove wrap  206  (potentially because the outer length of the outer groove wrap  206  is larger than the inner length of the inner groove wrap  204 ). Depending upon how much added traction may be desired, deployment may gradually vary from a minimal deployment, in which only the stake ends  185  of the plurality of stakes  180  projects beyond the wheel external diameter D W , to a maximal deployment. 
         [0059]    Rotation may be facilitated in several alternative and/or combined manners of any applicable, known and/or discovered means, such as, but not limited to, manually (for example, by an external, handheld crank) electrically (as a nonbinding example, by an electric motor and any known and/or discovered drive means) or hydraulically and/or pneumatically, to name a few illustrative examples. 
         [0060]    In case that a higher density of stakes may be called for, more than one spiral groove  200  may be formed on the scroll plate  170 . In such designs, the spiral grooves may interfit one within the other, and the plurality of stakes may be arranged so that if one of the stakes is associated with one of the spiral grooves, the following one of the stakes will be associated with a second spiral groove. 
         [0061]    While a number of exemplary aspects and embodiments have been discussed above, those of skill in the art will recognize certain modifications, permutations, adaptations, additions and/or sub-combinations thereof It is therefore intended that the follow appended claims and claims hereafter introduced be interpreted to include all such modifications, permutations, additions and sub-combinations as are within their true spirit and scope. Such exemplary modifications, permutations, adaptations, additions and/or sub-combinations may include, but are not limited to, variations of the construction of the stakes, the pins, the number of spiral grooves, pitch of the spiral groove, and/or construction and attachment details of the mobility device. 
         [0062]    To provide some illustrative, nonbinding and/or non-limiting examples, variations, modifications, permutations, adaptations, additions and/or sub-combinations may include inverting the direction the scroll plate is installed in the mechanism, a spiral through-groove formed in the scroll plate, installing the pin of any of the plurality of stakes as a simple beam supported between split stake ends, and other variations, modifications, permutations, adaptations, additions and/or sub-combinations which may be obvious to a person skilled in the art. 
         [0063]    It is to be understood some features are shown or described to illustrate the use of the present disclosure in the context of functional elements and such features may be omitted within the scope of the present disclosure and without departing from the spirit of the present disclosure as defined in the appended claims. 
         [0064]    All directional references (such as, but not limited to, inner, outer, axial, radial, center and/or central, periphery and/or peripheral, upper, lower, upward, downward, left, right, leftward, rightward, top, bottom, above, below, vertical, horizontal, clockwise, and counterclockwise, tangential, axial and/or any other similar references) are only used for identification purposes to aid the reader&#39;s understanding of the embodiments of the present disclosure, and may not create any limitations, particularly as to the position, orientation, or use unless specifically set forth in the claims. 
         [0065]    Similarly, joinder references (such as, but not limited to, attached, coupled, connected, and the like) are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements. As such, joinder references may not necessarily infer that two elements are directly connected and in fixed relation to each other. 
         [0066]    In some instances, components are described with reference to “ends” having a particular characteristic and/or being connected with another part. However, those skilled in the art will recognize that the present disclosure is not limited to components which terminate immediately beyond their points of connection with other parts. Thus, the term “end” should be interpreted broadly, in a manner that includes areas adjacent, rearward, forward of, or otherwise near the terminus of a particular element, link, component, part, member or the like. 
         [0067]    Additionally, all numerical terms, such as, but not limited to, “first”, “second”, “third”, or any other ordinary and/or numerical terms, should also be taken only as identifiers, to assist the reader&#39;s understanding of the various embodiments, variations and/or modifications of the present disclosure, and may not create any limitations, particularly as to the order, or preference, of any embodiment, variation and/or modification relative to, or over, another embodiment, variation and/or modification. 
         [0068]    Similarly, adjectives such as, but not limited to, “articulated”, “modified”, or similar, should be construed broadly, and only as nominal, and may not create any limitations, particularly as to the description, operation, or use, unless specifically set forth in the claims. 
         [0069]    In methodologies directly or indirectly set forth herein, various steps and operations are described in one possible order of operation, but those skilled in the art will recognize that steps and operations may be rearranged, replaced, or eliminated without necessarily departing from the spirit and scope of the present disclosure as set forth in the claims. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative only and not limiting. Changes in detail or structure may be made without departing from the spirit of the present disclosure as defined in the appended claims.
