Abstract:
In some embodiments, a hanger may removably mount a handpan to a wall. The hanger may comprise at least one elongate member, which may comprise a substrate-mounting-region disposed from a handpan-engagement-region. The substrate-mounting-region may mount to the wall so that the hanger may be mounted to the wall. The handpan-engagement-region may removably engage at least some portion of a cavity of the handpan. When the hanger may be mounted to the wall, the handpan-engagement-region may removably support the handpan so the handpan may be removably coupled to the wall. A length of the at least one elongate member may be of sufficient length to removably engage the cavity, but too long to pose dangers to passerbys. And a critical angle may not be too narrow, reducing the length and increasing a probability of the handpan falling; nor may the critical angle be too wide, providing an increased danger to passerbys.

       BACKGROUND OF THE INVENTION 
       [0005]    As musical instruments, handpans may be in of an idiophone class of instruments. Idiophone instruments may be any musical instrument that may create sound primarily by the musical instrument as a whole vibrating, without use of strings or membranes. 
         [0006]    A handpan may comprise an upper hemisphere and a lower hemisphere in integral communication with the upper hemisphere. The Upper hemisphere may be referred to as a “ding side.” The ding side may comprise a center note area, and a plurality of surrounding note areas (often elliptical). A boundary, e.g., a dividing rim, may divide the upper hemisphere from the lower hemisphere. 
         [0007]    The lower hemisphere may be known as the “gu side.” This gu side may comprise at least one bass cavity, hereinafter, a cavity. The cavity may comprise a cavity diameter. The cavity diameter, in various handpans, may vary from about 7 centimeters (cm) to about 9 cm. The cavity may comprise at least one externally accessible opening. The cavity may generally be cylindrical in shape, with side walls and closed at a distal end opposite of the at least one externally accessible opening. A depth of the cavity, in various handpans, may vary from about 18 cm to about 22 cm. The depth of the cavity, in various handpans, may vary from about 15.5 cm to about 26 cm. This depth of the cavity may extend into a volume partially circumscribed by the upper hemisphere. 
         [0008]    The handpan may comprise a total outside diameter, as measured from one side of the dividing rim to an opposing side of the dividing rim. In some handpans, this total outside diameter may be about 52 cm. In some handpans, this total outside diameter may be about 48 cm to about 60 cm. A total height, as measured from the lower hemisphere to a farthest point of the upper hemisphere, may be greater than the depth of the cavity. In various handpans, this total height may be about 24 cm to about 26 cm. In various handpans, this total height may be about 16 cm to about 29 cm. 
         [0009]    In terms of mass, various handpans may be about 5.44 kg (i.e., 12 pounds [lbs] in weight). In terms of mass, various handpans may be about 3.18 kg (7 lbs) to about 7.26 kg (16 lbs). 
         [0010]    Handpan musical instruments may also be known as: “hand pan,” HANG, HALO, BELLS, GUBAL, sound sculpture, and the like; and with various styles, dimensions, and design generations from sources such as PanArt, Pantheon Steel, BellArt, and the like. 
         [0011]    Currently such handpans may be stored by users in a traveling bag, such as a luggage piece configured to house one or more handpans. However, there is currently no hanging nor mounting means for removably mounting the handpan to a substrate such as a wall. It would be desirable to removably mount the handpan to the substrate, for a storage purpose and/or for an ornamental display purpose, as removably mounting the handpan to the substrate may present a natural beauty of the handpan, much in the way a three dimensional sculpture might be displayed upon a wall. 
         [0012]    Existing hooks and hangers have been attempted to be used for this removable substrate mounting purpose and found undesirable at best or a plain failure as more often the case. Existing art of hooks and hangers have several problems. 
         [0013]    First, many existing hooks and/or hangers are structurally configured to removably hold garments, such as jackets or hats. Such existing hooks and/or hangers do not extend far enough into the handpan cavity to provide a reliable mounting means, that is, the handpan either falls off of the existing hook and/or the existing hanger; or easily falls off the existing hook and/or the existing hanger. The reason such existing garment hooks and/or hangers do not extend sufficiently into the handpan cavity, is because a length of the existing garment hook and/or hanger arm is too short; and an angle of divergence (as measured from the arm of the existing hook or the existing hanger to the substrate) is too narrow, often being less than 50 degrees. 
         [0014]    Second, such existing hooks and/or such existing hangers generally comprise a transverse width that is so small (too narrow) as not to provide any side-to-side stability when the handpan cavity may be removably mounted or attempted to be removably mounted to the existing hook and/or the existing hanger. That is, because of the narrowness of the existing hook and/or the existing hanger, the handpan is easily knocked off of the existing hook and/or the existing hanger. This may damage the handpan and may also provide a dangerous and undesirable condition wherein the foreseeable and probable fall may injure someone, other property, and/or animals. 
         [0015]    Third, such existing hooks and/or such existing hangers are not made to continually sustain constant static loads of about 12 pounds (lbs) (or about 7 to 16 lbs for other handpans), a typical weight of handpans, and over a short time such existing hooks and/or hangers fail by breaking, fail by coming detached from the substrate, and/or bending or deforming out of shape to where the handpan may not be removably mounted to the existing hook and/or the existing hanger. For example, some such existing hooks and/or existing hangers have been tested and failed by snapping at about 6 months of use. 
         [0016]    Some existing hooks and/or existing hangers, e.g., those in use with various shelving systems, may have a sufficient arm length to removably engage a sufficient portion of the handpan cavity, but this class of existing hooks and/or hangers has at least two other problems. One, when such existing hook and/or hanger is not in use, this sufficient arm length often presents a danger to those passing nearby because the arm length is too long. And two, the angle of divergence of this sufficient arm length from the substrate is too wide, often around 90 degrees or more than 70 degrees, which contributes to problem of the arm protruding too far from the substrate. These existing longer shelving arms also suffer the problem with the existing garment hooks and/or the existing hangers of being too narrow in transverse width such that handpan is too wobbly when mounted on the too long and narrow shelving arm, easily falling off. Further, because of these existing longer shelving arms being too long and too minimal in transverse width, the handpan tends to hang with the upper hemisphere ding side facing more towards the ground and not parallel (or not close to parallel) with the substrate (e.g., wall), which detracts from displaying the natural beauty of the handpan. 
         [0017]    There is a need in the art for a means to removably mount the handpan to the substrate, i.e., a need for a specifically structured hanger for removably mounting of the handpan to the substrate or within a proximity of the substrate, wherein the arm length is not too short, nor too long, and the angle of divergence, a critical angle, may not be too wide, nor too narrow. 
         [0018]    It is to these ends that the present invention has been developed. 
       BRIEF SUMMARY OF THE INVENTION 
       [0019]    To minimize the limitations in the prior art, and to minimize other limitations that will be apparent upon reading and understanding the present specification, the present invention describes hangers, landing strips, systems of at least the hanger, and/or methods of using the hanger. 
         [0020]    In some embodiments, a hanger may removably mount a handpan to a substrate, such as a wall. In some embodiments, the hanger may comprise at least one elongate member, which may comprise a substrate-mounting-region disposed from a handpan-engagement-region. In some embodiments, the substrate-mounting-region may mount to the substrate so that the hanger may be mounted to the substrate. In some embodiments, the handpan-engagement-region may removably engage a cavity of the handpan. When the hanger may be mounted to the substrate, the handpan-engagement-region may removably support the handpan so the handpan may be removably mounted in proximity to the substrate. A length of the at least one elongate member may be of sufficient length to removably engage the cavity, but too long to pose dangers to passerbys when the hanger may not be in use, but still mounted to the substrate. And a critical angle may not be too narrow, reducing the length and increasing a probability of the handpan falling from the hanger; nor may the critical angle be too wide, providing an increased danger to passerbys when the hanger may not be in use, but still mounted to the substrate. In some embodiments, the hanger may comprise a transverse-width that may be larger than at least some existing hangers and at least some existing hooks, but still less than a cavity diameter of the cavity, wherein such a transverse-width may minimize wobbliness of the handpan upon the hanger. 
         [0021]    It is an objective of the present invention to provide a hanger for removably mounting a handpan to a substrate or within proximity of the substrate. 
         [0022]    It is another objective of the present invention to provide the hanger for removably mounting the handpan to the substrate or within proximity of the substrate, in manner which may be reliable and/or safe, such that falls of the handpan off of the hanger may be minimized. 
         [0023]    It is another objective of the present invention to provide the hanger for removably mounting the handpan to the substrate or within proximity of the substrate, such that the handpan is not too wobbly upon the hanger. 
         [0024]    It is another objective of the present invention to provide the hanger for removably mounting the handpan to the substrate or within proximity of the substrate, in manner that protects the handpan from impacts and/or scratches from the hanger. 
         [0025]    It is another objective of the present invention to provide the hanger and/or a landing strip for removably mounting the handpan to the substrate or within proximity of the substrate, in manner that protects the substrate from impacts and/or scratches from the handpan. 
         [0026]    It is another objective of the present invention to provide the hanger for removably mounting the handpan to the substrate or within proximity of the substrate, such that the handpan hangs by gravity upon at least some portion of the hanger. 
         [0027]    It is yet another objective of the present invention to provide the hanger for removably mounting the handpan to the substrate or within proximity of the substrate, such that the handpan removably mounts by frictional gripping between the hanger and the handpan. 
         [0028]    These and other advantages and features of the present invention are described herein with specificity so as to make the present invention understandable to one of ordinary skill in the art, both with respect to how to practice the present invention and how to make the present invention.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0116]    Various embodiments of a hanger may be described, disclosed, and claimed herein. Such hangers may be used to removably mount (hang) a handpan to a substrate or within proximity of the substrate. This disclosure may also describe, disclose, and claim method(s) for removably mounting the handpan to the substrate or within proximity of the substrate. This disclosure may also describe, disclose, and claim system(s) for removably hanging the handpan to the substrate or within proximity of the substrate. 
         [0117]    Note, hanging, including removable hanging, may be a sub-set of mounting, and of removable mounting. 
         [0118]    The handpan may be prior art and the handpan may be a musical instrument in the idiophone class of musical instruments. The various embodiments of the invention described, disclosed, and claimed herein all may operate upon handpans with at least one externally accessible cavity, wherein the various embodiments may access and use this cavity for removably mounting the handpan to the substrate or within proximity of the substrate. 
         [0119]    For example, and without limiting the scope of the present invention, the substrate may be a wall. The substrate may be substantially vertical, at least in a region wherein the hanger may be mounted (attached) to the substrate. The substrate may be substantially flat, at least in the region wherein the hanger may be mounted (attached) to the substrate. 
         [0120]    Note, such hangers, as described and disclosed herein, may also be used to removably mount (hang) other articles to the substrate or within proximity of the substrate. For example, and without limiting the scope of the present invention, tongue drums with a cavity may also be removably mounted (hung) like the handpan upon the hanger. Tongue drums may also be known as steel tongue drums. 
         [0121]    In the following discussion that addresses a number of embodiments and applications of the present invention, reference is made to the accompanying drawings that form a part thereof, where depictions are made, by way of illustration, of specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and changes may be made without departing from the scope of the invention. 
         [0122]    A  FIG. 1  series of figures may comprise  FIG. 1A  through  FIG. 1E . The  FIG. 1  series of figures may depict prior art, a musical instrument, often known as a “hand pan,” “handpan,” HANG, HALO, BELLS, GUBAL, sound sculpture, and the like; and with various styles, dimensions, and design generations from sources such as PanArt, Pantheon Steel, BellArt, and the like. Such prior art may be referred to herein as the “handpan.” As a musical instrument, handpans may be in the idiophone class of instruments. Idiophone instruments may be any musical instrument that may create sound primarily by the musical instrument as a whole vibrating, without use of strings or membranes. 
         [0123]    The various embodiments of the invention described, disclosed, and claimed herein all may operate upon handpans with at least one externally accessible cavity, wherein the various embodiments may access and use this cavity for removably mounting the handpan to a substrate or within proximity of the substrate. Similarly, such hangers may also operate upon tongue drums with an accessible cavity. 
         [0124]      FIG. 1A  may depict a handpan  100  (prior art), shown from a top perspective view.  FIG. 1B  may depict handpan  100 , but shown from a bottom perspective view.  FIG. 1C  may depict handpan  100 , but shown from a top view.  FIG. 1D  may depict handpan  100 , but shown from a bottom view.  FIG. 1E  may depict handpan  100 , but shown from a side view. 
         [0125]    As shown in  FIG. 1A  (and  FIG. 1E ) handpan  100  may comprise an upper hemisphere  101  and a lower hemisphere  102 . Upper hemisphere  101  may be referred to as the “ding side.” The ding side may comprise a center note area  103 , and a plurality of surrounding note areas  104  (often elliptical in appearance). A boundary, dividing rim  105 , may divide upper hemisphere  101  from lower hemisphere  102 . A plane dividing upper hemisphere  101  from lower hemisphere  102  along dividing rim  105  may be handpan-plane  106 . See e.g.,  FIG. 1E  (and  FIG. 2A ). 
         [0126]    Lower hemisphere  102 , better depicted in  FIG. 1B , may be known as the “gu side.” This gu side may comprise at least one bass cavity  110 , herein after, cavity  110 . Cavity  110  may comprise cavity diameter  111 . Cavity diameter  111 , in various handpans, may vary from about 7 cm to about 9 cm. Cavity  110  may comprise at least one externally accessible opening  112  (opening  112 ). Cavity  110  may generally be cylindrical in shape, with side walls  114  (e.g. a top cavity wall  113  shown in  FIG. 5A ), and closed at a distal end opposite the at least one externally accessible opening. For side walls  114  see  FIG. 5B  and  FIG. 5C . Continuing discussing the  FIG. 1  series of figures of prior art handpan  100 , a depth of cavity  110 , in various handpans  100 , may vary from about 18 cm to about 22 cm. Depth of cavity  110 , in various handpans  100 , may vary from about 15.5 cm to about 26 cm. This depth of cavity  110  may extend into a volume partially circumscribed by upper hemisphere  101 . 
         [0127]    The structure and/or geometry of cavity  110  may be critical, as the various embodiments of the hanger(s) may removably mount to cavity  110 , in order to mount handpan  100  to the substrate or within proximity to the substrate. 
         [0128]    A total outside diameter  120  of handpan  100 , as measured from one side of dividing rim  105  to an opposing side of dividing rim  105 , may be depicted in  FIG. 1C  and  FIG. 1E . In some handpans  100 , this total outside diameter  120  may be about 52 cm. In some handpans  100 , this total outside diameter  120  may be about 48 cm to about 60 cm. A total height  125 , as measured from lower hemisphere  102  to a farthest point of upper hemisphere  101 , may be depicted in  FIG. 1E . In various handpans  100 , total height  125  may be greater than the depth of cavity  110 . In various handpans  100 , total height  125  may be about 24 cm to about 26 cm. In various handpans  100 , total height  125  may be about 16 cm to about 29 cm. 
         [0129]    In terms of mass, various handpans  100  may be about 5.44 kg (i.e., 12 pounds [lbs.] in weight). In terms of mass, various handpans  100  may be about 3.18 kg (7 lbs.) to about 7.26 kg (16 lbs.). 
         [0130]    A  FIG. 2  series of figures, may depict handpan  100  removably mounted to a substrate  1001 , by use of various embodiments of the invention, which may not be visible (depicted) in the  FIG. 2  series of figures. The  FIG. 2  series of figures may demonstrate purposes and functions of the various embodiments of the hangers, i.e., to provide a removable hanging means and/or a removable mounting means for removably mounting handpan  100  to substrate  1001  or within proximity of substrate  1001 . While handpan  100  may be a musical instrument, upon removable mounting to substrate  1001 , such mounting may serve several purposes, including, but not limited to, providing a useful function of storing handpan  100  out of the way; and secondly, by removably mounting handpan  100  to substrate  1001  or within proximity of substrate  1001 , such removable mounting serves a display purpose, which may show off a natural beauty of handpan  100 , as a generally hand crafted three dimensional sculpture. The  FIG. 2  series of figures may comprise  FIG. 2A  through  FIG. 2D . 
         [0131]      FIG. 2A  may depict handpan  100  removably mounted upon substrate  1001 , shown from a side view. The means for mounting (e.g., the hanger) may not be depicted in  FIG. 2A .  FIG. 2B  may depict handpan  100  removably mounted upon substrate  1001 , shown from a front view. The means for mounting (e.g., the hanger) may not be depicted in  FIG. 2B . 
         [0132]    In some embodiments, structure of the hanger may be such that when the hanger may be mounted to substrate  1001  and an handpan-engagement-region of the hanger may be removably engaging at least a portion of cavity  110  of handpan  100 , such that handpan-plane  106  may be substantially parallel with a surface plane of the substrate, i.e., and an angle-off-from-parallel  207  between the handpan-plane  106  and the surface plane of the substrate may be about zero degrees. See e.g.,  FIG. 2A  (and  FIG. 5A ). For angle-off-from-parallel  207  see  FIG. 2C  and  FIG. 2D . 
         [0133]      FIG. 2C  may depict handpan  100  removably hung upon substrate  1001 , but where angle-off-from-parallel  207  may be greater than zero degrees, shown from a side view. The means for mounting (e.g., the hanger) may not be depicted in  FIG. 2C .  FIG. 2D  may depict handpan  100  removably hung upon substrate  1001 , but where angle-off-from-parallel  207  may be greater than zero degrees, shown from a side view. The means for mounting (e.g., the hanger) may not be depicted in  FIG. 2D .  FIG. 2C  and  FIG. 2D  may differ from each other, in that a tilt of angle-off-from-parallel  207  may be opposite, i.e., in  FIG. 2C , a top of handpan  100  may be tilted away from substrate  1001 ; whereas in  FIG. 2D , a bottom of handpan  100  may be tilted away from substrate  1001 —where top and bottom may be with respect to a floor (not depicted), where substrate  1001  may be substantially perpendicular to such a floor. 
         [0134]    In some embodiments the hanger structure may permit angle-off-from-parallel  207  between handpan-plane  106  and the surface plane of the substrate to be up to about 12 degrees. See e.g.,  FIG. 2C  and  FIG. 2D  (see also,  FIG. 5B  and  FIG. 5C ). 
         [0135]    Note, with respect to  FIG. 2A ,  FIG. 2C , and  FIG. 2D , the embodiments of the the hanger(s) which may permit substantially parallel removable mounting or a removable mounting with angle-off-from-parallel  207  at greater than zero degrees (e.g., up to about 12 degrees), may be different embodiments of the hangers. 
         [0136]    A  FIG. 3  series of figures may depict an exemplary embodiment of a hanger  300 . In the  FIG. 3  series of figures, handpan  100  may not be depicted and substrate  1001  may not be depicted. For example, hanger  300  may be the hanger used in  FIG. 2A  and  FIG. 2B , but that is not depicted in  FIG. 2A  and  FIG. 2B . The  FIG. 3  series of figures may comprise  FIG. 3A  through  FIG. 3F . 
         [0137]      FIG. 3A  may depict the exemplary embodiment of  300  hanger for removable mounting handpan  100  within proximity to substrate  1001 , shown from a perspective view. Handpan  100  and substrate  1001  may not be depicted in  FIG. 3A .

In some embodiments, hanger  300  may comprise at least one elongate member  301 . In some embodiments, at least one elongate member  301  may be substantially rigid. 
         [0139]    In some embodiments, at least one elongate member  301  may comprise a substrate-mounting-region  302  disposed from a handpan-engagement-region  303 . In some embodiments, substrate-mounting-region  302  may be configured structurally to mount to substrate  1001  so that hanger  300  may be mounted to substrate  1001 . In some embodiments, handpan-engagement-region  303  may be configured structurally to engage at least some portion of cavity  110  of handpan  100 . In some embodiments, when hanger  300  may be mounted to substrate  1001 , handpan-engagement-region  303  may removably support handpan  100  so handpan  100  may be removably mounted (e.g., hung) in proximity to substrate  1001 . See e.g.,  FIG. 5A . 
         [0140]    In some embodiments, “in proximity to the substrate” may mean at least some portion of handpan  100  may be either in removable physical contact with substrate  1001  (or a landing strip). Or at least some portion of handpan  100  may be within 4 cm of substrate  1001  (or the landing strip). See e.g.,  FIG. 2A ,  FIG. 2C ,  FIG. 2D ,  FIG. 5A ,  FIG. 5B , and  FIG. 5C .

In some embodiments, substrate contacting surface  311  may be substantially flat. In some embodiments, the substrate-mounting-region  302  may be designated as a “base” of at least one elongate member  301  or the base of hanger  300 . 
         [0142]    In some embodiments, substrate-mounting-region  302  may comprise a substrate-attachment. In some embodiments, the substrate-attachment may provide structure to mount substrate-mounting-region  302  to substrate  1001 .

Such a system of hooks and complimentary loops may be a VELCRO type of attachment (removable fastener) system. This substrate-attachment embodiment is not explicitly depicted in the figures. 
         [0145]    In some embodiments, the substrate-attachment of substrate-mounting-region  302  may comprise an adhesive located on the substrate contacting surface  311 . In some embodiments, such an adhesive may permit permanent (or near permanent) mounting of hanger  300  to substrate  1001 . In some embodiments, such an adhesive may be a removable adhesive, permitting removable mounting of hanger  300  to substrate  1001 . These adhesive substrate-attachment may not be explicitly depicted in the figures. 
         [0146]    In some embodiments, the substrate-attachment substrate-mounting-region  302  may comprise a suction means (e.g., at least one suction cup) located on substrate contacting surface  311  for when substrate  1001  may comprise a non-porous surface and substantially flat surface, such as, but not limited to glass, plastics, and/or metals. This substrate-attachment embodiment is not explicitly depicted in the figures. 
         [0147]    In some embodiments, at least one elongate member  301  may comprise a flat bar structure. For example, see generally, the  FIG. 3  series of figures. For example, and without limiting the scope of the present invention, the flat bar may be about ⅛ inch (0.32 cm) thick by about 1 inch (2.54 cm) in transverse width (e.g., transverse-width  308  shown in  FIG. 3B ). In some embodiments, at least one elongate member may comprise a round bar, see e.g.,  FIG. 7C .

In some embodiments, the hypotenuse-region  306  may be disposed between substrate-mounting-region  302  and handpan-engagement-region  303 . In some embodiments, hypotenuse-region  306  may be substantially linear. In some embodiments, hypotenuse-region  306  may be designated as an “arm” of the at least one elongate member  301  or the arm of hanger  300 . In some embodiments, hypotenuse-region  306  may be designated as at least a portion of the arm of the at least one elongate member  301  or the arm of hanger  300 ; wherein, that arm terminates in handpan-engagement-region  303 , specifically at a terminal-point  315 .

In some embodiments, first-bend  304  may be disposed between substrate-mounting-region  302  and hypotenuse-region  306 . In some embodiments, first-bend  304  may link substrate-mounting-region  302  to the hypotenuse-region  306 . In some embodiments of hanger  300 , first-bend  304  may be fixed, i.e., not variable. In some embodiments, when hanger  300  may be mounted to substrate  1001 , first-bend  304  may bend at least one elongate member  301 , e.g., hypotenuse-region  306 , away from substrate  1001 .

In some embodiments, when hanger  300  may be mounted to substrate  1001 , second-bend  305  may bend at least one elongate member  301 , e.g. handpan-engagement-region  303 , towards substrate  1001 . 
         [0151]    Continuing discussing  FIG. 3A , in some embodiments, at least one elongate member  301  may comprise an upper substrate facing surface  313  and an externally facing surface  314  disposed opposite of upper substrate facing surface  313 . Note, externally facing surface  314  may not be depicted in  FIG. 3A , instead see  FIG. 3C ,  FIG. 3D , and  FIG. 3E . In some embodiments, substrate contacting surface  311  may be a sub-set of upper substrate facing surface  313 . In some embodiments, external surface  312  may be a sub-set of the externally facing surface  314 . 
         [0152]    Continuing discussing  FIG. 3A , in some embodiments, handpan-engagement-region  303  may removably engage at least a portion of cavity  110  of handpan  100  by providing support structure for top cavity wall  113  of handpan  100  to rest by gravity upon some portion of handpan-engagement-region  303 . “Top” may be with respect to a floor associated with substrate  1001  (e.g., a wall). Top cavity wall  113  may be depicted in  FIG. 5A . In some embodiments, handpan-engagement-region  303  may be designated as a “head” of hanger  300 .

Transverse-width  308  may be larger than thickness  309 . Transverse-width  308  may be substantially perpendicular to thickness  309 . In some embodiments, at least one elongate member  301  may comprise a singular uniform transverse-width  308 ; e.g., as shown in the  FIG. 3  series of figures. In some embodiments, transverse-width  308  may be less than cavity diameter  111 , so that at least handpan-engagement-region  303  may fit removably within cavity  110 . In some embodiments, handpan-engagement-region  303  may comprise its own transverse width, which may differ from transverse-width  308  of a remainder of at least one elongate member  301 . In some embodiments, the transverse width (e.g., transverse-width  708 , see  FIG. 7A ) of handpan-engagement-region  303  may be less than cavity diameter  111 , so that at least handpan-engagement-region  303  may fit removably within cavity  110 ; but greater than transverse-width  308  of hypotenuse-region  306 .

         [0162]    Discussing  FIG. 4C , in some embodiments, hanger  300  when mounted to substrate  1001 , may comprise formation of a critical angle  401 . In some embodiments, critical angle  401  may be measured from substrate  1001  to upper substrate facing surface  313  of hypotenuse-region  306 . In some embodiments, a vertex of critical angle  401  may be centered in first-bend  304 . 
         [0163]    In some embodiments, critical angle  401  may be in a range of about 50 degrees to about 70 degrees. In some embodiments, critical angle  401  may be about 59 degrees to about 66 degrees. In some embodiments, critical angle  401  may be about 63 degrees to about 65 degrees. In some embodiments, critical angle  401  may be about 52 degrees to about 58 degrees. In some embodiments, critical angle  401  may be about 53 degrees to about 55 degrees. Factors affecting critical angle  401  may include whether hanger  300  may have covering  601 , e.g., as depicted in  FIG. 6 ; and/or whether or not a landing pad (e.g., landing pad  900  as depicted in the  FIG. 9  series of figures) may be disposed between substrate  1001  and substrate-mounting-region  302 . 
         [0164]    Continuing discussing  FIG. 4C , in some embodiments, a shortest distance from terminal point  315  to substrate  1001 , when hanger  300  may be mounted to substrate  1001 , may be an orthogonal distance  410 . In some embodiments, orthogonal distance  410  may be in a range of about 5.00 cm to about 9.00 cm. In some embodiments, orthogonal distance  410  may be in a range of about 6.30 cm to about 8.30 cm. Factor affecting orthogonal distance  410  may include whether hanger  300  may have covering  601 , e.g., as depicted in  FIG. 6 ; and/or whether or not a landing pad (e.g., landing pad  900  as depicted in the  FIG. 9  series of figures) may be disposed between substrate  1001  and substrate-mounting-region  302 ; as well as a linear run dimension of hypotenuse-region  306 . For example, and without limiting the scope of the present invention, the linear run dimension of hypotenuse-region  306  may be in a range of about 4.40 cm to about 8.00 cm. 
         [0165]    In some embodiments, a cavity protrusion distance may approximate orthogonal distance  410 , where the cavity protrusion distance may be defined as the shortest distance from substrate  1001  that terminal point  315  of handpan-engagement-region  303  may protrude into cavity  110  handpan  100  that may be removably mounted to hanger  300 , when hanger  300  may be mounted to substrate  1001 . In some embodiments, critical angle  401  may be defined (constrained) by a first-bend angle  404 . 
         [0166]    Continuing discussing  FIG. 4C , when hanger  300  may be mounted to substrate  1001 , at least one elongate member  301  may comprise a minimal length, such that terminal point  315  may be at least 5 cm from substrate  1001  (when a portion of substrate  1001  may be substantially flat). In some embodiments, this distance may be orthogonal distance  410 . This minimal length of at least one elongate member  301  may be constrained (defined and/or determinable) by: (1) an angle of first-bend  304  (hereinafter, first-bend angle  404 ) between substrate-mounting-region  302  and externally facing surface  314  of hypotenuse-region  306 ; (2), a different angle of second-bend  305  between upper substrate facing surface  313  of hypotenuse-region  306  and upper substrate facing surface  313  of handpan-engagement-region  303  (hereinafter, second-bend-angle  405 ); and (3) the linear run dimension of hypotenuse-region  306  and a length of the handpan-engagement-region  303  running from terminal point  315  to second-bend  305 . In some embodiments of hanger  300 , orthogonal distance  410  of at least 5 cm (e.g., 6.50 cm or 8.26 cm) (e.g., along with critical angle  401  of about 52 degrees), may provide for a minimum protrusion distance into cavity  110  required for hanger  300  to securely support handpan  100  from falling from hanger  300 , when handpan-engagement-region  303  may be removably engaging the least some portion of cavity  110  and hanger  300  may be mounted to substrate  1001 . 
         [0167]    Continuing discussing  FIG. 4C , in some embodiments, first-bend  304  may be defined by first-bend angle  404 . In some embodiments, first-bend angle  404  may comprise an angle as measured from external surface  312  of substrate-mounting-region  302  to externally facing surface  314  of hypotenuse-region  306 . In some embodiments, first-bend angle  404  may comprise an angle as measured from substrate  1001  to externally facing surface  314  of hypotenuse-region  306 . In some embodiments, first-bend angle  404  may be about 101 to 130 degrees. In some exemplary embodiments, this angle may be 103 to 128 degrees. This angle is almost (offset by thickness  309  of at least one elongate member  301 , which may also include covering  601  in some embodiments) complimentary to critical angle  401 , in a geometry terminology sense of “complimentary angle” wherein two such angles add to 180 degrees. 
         [0168]    Continuing discussing  FIG. 4C , in some embodiments, second-bend  305  may be defined by second-bend angle  405 . In some embodiments, second-bend angle  405  may comprise an angle as measured from upper substrate facing surface  313  of handpan-engagement-region  303  to upper substrate facing surface  313  of hypotenuse-region  306 , with a vertex at second-bend  305 . In some embodiments, this angle may be about 30 to 70 degrees. In some embodiments, this angle may be 30 to 50 degrees.

In the  FIG. 5  series of figures the dashed lines may indicate the outline of cavity  110  of handpan  100 . 
         [0171]      FIG. 5A  may depict the exemplary embodiment of hanger  300  while hanger  300  (or a portion thereof) may be removably inserted into cavity  110  of handpan  100  and while hanger  300  may be mounted to the substrate  1001 , shown from a side view, with transparency to show the outline of cavity  110  and how hanger  300  may removably engage at least a portion of cavity  110 . 
         [0172]    In  FIG. 5A , hanger  300  may be mounted to substrate  1001  and handpan-engagement-region  303  may be removably engaging the at least the portion of cavity  110  of handpan  100 , such that handpan-plane  106  may be substantially parallel with the surface plane of the substrate, i.e., and an angle-off-from-parallel  207  between the handpan-plane  106  and the surface plane of the substrate may be about zero degrees. See e.g.,  FIG. 5A  (and  FIG. 2A ).

For example, and without limiting the scope of the present invention, this some portion of handpan-engagement-region  303  may be terminal point  315 . 
         [0174]      FIG. 5B  may depict handpan  100  removably mounted upon substrate  1001 , where angle-off-from-parallel  207  may be greater than zero degrees, shown from a side view.

(See  FIG. 7C  discussion below for discussion of hanger  780 .) 
         [0176]      FIG. 5B  and  FIG. 5C  may differ from each other, in that a tilt of angle-off-from-parallel  207  may be opposite, i.e., in  FIG. 5B , a top of handpan  100  may be tilted away from substrate  1001 ; whereas in  FIG. 5C , a bottom of handpan  100  may be tilted away from substrate  1001 —where top and bottom may be with respect to the floor (not depicted); wherein this floor may be substantially perpendicular to substrate  1001 . Such a tilt of handpan  100  depicted in  FIG. 5B  and/or as depicted in  FIG. 5C  may be accomplished with either hanger  750  or hanger  780 . 
         [0177]    In some embodiments, hanger  750  or hanger  780  may permit angle-off-from-parallel  207  between handpan-plane  106  and the surface plane of the substrate to be up to about 12 degrees. See e.g.,  FIG. 5B  and  FIG. 5C  (see also,  FIG. 2C  and  FIG. 2D ). 
         [0178]      FIG. 6  may depict a side view of hanger  300 , wherein at least a portion of hanger  300  may be substantially covered by covering  601 . Also, in embodiments where covering  601  may cover the sides of hanger  300 , in addition to covering upper substrate facing surface  313  and externally facing surface  314 ,  FIG. 6  may depict a cross sectional side view of hanger  300 , wherein at least a portion of hanger  300  may be substantially covered by covering  601 . 
         [0179]    In some embodiments, hanger  300  may be replaced with hanger  750  or hanger  780  in  FIG. 6 . In some embodiments, hanger  300  (hanger  750  or hanger  780 ) may comprise covering  601 . In some embodiments, covering  601  may serve a protection function. Covering  601  may protect handpan  100  from impacts and scratches, such as, but not limited to, metal on metal scratches. Covering  601  may also protect at least one elongate member  301  from scratches and impacts. In some embodiments, covering  601  may protect a user from injury or undesirable physical contact with at least one elongate member  301 . In some embodiments, covering  601  may serve an ornamental function, by adding different finishes, colors, and looks to hanger  300  (or to hanger  750  or to hanger  780 ). 
         [0180]    In some embodiments, at least a portion of at least one elongate  301  may be substantially or completely covered by covering  601 . In some embodiments, covering  601  may cover any portion of at least one elongate member  301  that may come into removable physical contact with cavity  110 . In some embodiments, covering  601  may not cover substrate contacting surface  311 . In some embodiments, covering  601  may not cover sides of at least one elongate member  301 . 
         [0181]    In some embodiments, covering  601  may be selected from one or more of the following: a foam, an elastomer, a rubber (natural and/or synthetic), a plastic, an enamel, a paint, a powder coating, combinations thereof, and/or the like. For example, and without limiting the scope of the present invention, covering  601  may be applied as a dip and/or as an extruded material slipped over at least the portion of at least one elongate member, wherein subsequent heat shrinking may be used in some embodiments. For example, and without limiting the scope of the present invention, covering  601  may be a vinyl covering and/or vinyl coating. For example, and without limiting the scope of the present invention, covering  601  may be a plastisol coating. 
         [0182]    Note, including of covering  601  to a given hanger embodiment, increases the effective thickness of that hanger. For example, and without limiting the scope of the present invention, with some embodiments of covering  601  applied to hanger  300 , an effective dimension of thickness  309  may be about in a range of about 0.79 cm to about 1.30 cm. For example, and without limiting the scope of the present invention, with some embodiments of covering  601  applied to hanger  300 , an effective dimension of transverse-width  308  may be about 3.22 cm. 
         [0183]    A  FIG. 7  series of figures may depict three figures of additional embodiments of hangers. Each  FIG. 7  figure may depict a different hanger embodiment.

That is, terminal point  315  may terminate in cylindrical head structure  717 . In some embodiments, handpan-engagement-region (e.g.,  303 ) may comprise a dimension greater than transverse-width  308  of the flat rod portion of hypotenuse-region  306 , wherein this greater dimension is the transverse width of cylindrical head structure  717 , which is denoted as transverse-width  708 . In some embodiments, transverse-width  708  of handpan-engagement-region  303  may be less than cavity diameter  111 , so that the handpan-engagement-region  303  may fit removably within cavity  110 . Some handpan  100  cavities  110  may range in cavity diameter  111  of about 7 cm to about 9 cm. In some embodiments, transverse-width  708  may be about the same as cavity diameter  111 , in embodiments wherein handpan-engagement-region  303  removably engages cavity  110  by friction and not just by gravity. 
         [0185]    In some embodiments, handpan-engagement-region (e.g.,  303 ) may comprises a three dimensional shape. The three dimensional shape may be selected from the group comprising: regular polygons, irregular polygons, ovoids, cylinders, spheres, cones, combinations thereof, and/or the like.

         [0190]    In some embodiments (e.g., as depicted in  FIG. 7B ), the span may be sub-divided into a first-span  752  and a second-span  753 . In some embodiments, first-span  752  may be separated from second-span  753  by a fourth-bend  754 . In some embodiments, fourth-bend  754  may link first-span  752  to second-span  753 . In some embodiments, fourth-bend  754  may be disposed between second-bend  305  and third-bend  751 . In some embodiments, first-bend  304 , second-bend  305 , third-bend  751 , and fourth-bend  754  may angle in a way to form the spiral shape of the at least one elongate member.

See e.g.,  FIG. 5C . 
         [0193]    In some embodiments, the radial spiral  781  may approximate a three dimensional ovoid, sphere, disk, cone shape, or other similar shape. See e.g.,  FIG. 7C  and  FIG. 5C . 
         [0194]    In some embodiments, the at least one elongate member (e.g.,  301 ) may be substantially constructed of one or more of: a metal, a thermoformed plastic, a ceramic, a glass, a wood, a stone, a granite, a composite, a laminate, combinations thereof, and/or the like. 
         [0195]    In some embodiments, the metal may be selected from one or more of the following steel, stainless steel, aluminum, copper, brass, tin, combinations thereof, and/or the like. 
         [0196]    In some embodiments, the at least one elongate member (e.g.,  301 ) may be able to withstand (without any deformation affecting performance) a static load of 250 pounds (lbs.) or less. 
         [0197]    In some embodiments, the at least one elongate member (e.g.,  301 ) may be substantially constructed of one or more thermoplastics suitable for injection molding. For example, and without limiting the scope of the present invention, various exemplary embodiments of at least one elongate member  301  may be substantially constructed of one or more materials of acrylic, acrylonitrile-butadiene styrene (ABS), polyvinyl chloride (PVC), polycarbonate, nylon, polypropylene, polyethylene (e.g., HDPE), combinations thereof, and/or the like. Such thermoplastics may comprise fillers for additional structural strength such as glass fibers and/or the like. Such thermoplastics may comprise additional ribbing structures to add additional structural support. 
         [0198]    Note with respect to the materials of construction, it is not desired nor intended to thereby unnecessarily limit the present invention by reason of such restricted disclosure. 
         [0199]    A  FIG. 8  series of figures and a  FIG. 9  series of figures may each depict two different embodiments of “landing strip” structures, for use with various hanger embodiments (e.g.,  300 ,  750 , and/or  780 ). In some embodiments, these landing strips may be accessories to the hangers (e.g.,  300 ,  750 , and/or  780 ).

         [0211]    As noted, in some embodiments, landing strip  800  and/or  900  may function as a cushion, a separator, and/or a divider. In some embodiments, landing strip  800  and/or landing strip  900  may be substantially constructed of one or more of an elastomer (e.g., rubber, silicone, and the like), a metal, a thermoformed plastic, a ceramic, a glass, a wood, a composite, a fabric, a textile, a cloth, a laminate, combinations thereof, and/or the like. In some embodiments, raised edge  902  may be substantially constructed of one or more of an elastomer (e.g. rubber, silicone, and the like), a metal, a thermoformed plastic, a ceramic, a glass, a wood, a composite, a laminate, a fabric, a textile, a cloth, combinations thereof, and/or the like. 
         [0212]    In some embodiments, a method for removably mounting handpan  100  in proximity to a substrate  1001  may be disclosed, described, and/or claimed. In some embodiments, the method may, comprise the steps of: 
         [0213]    Step (a): mounting a hanger (e.g.,  300 ,  750 , and/or  780 ) to substrate  1001 . As noted, such hangers may comprise at least one elongate member  301 , wherein at least one elongate member  301  may comprise: substrate-mounting-region  302  disposed from handpan-engagement-region  303 . As noted, in some embodiments, substrate-mounting-region  302  may be structurally configured to mount to substrate  1001  so that the hanger may be mounted to substrate  1001 . As noted, in some embodiments, handpan-engagement-region  303  may be structurally configured to engage the at least some portion of cavity  110  of handpan  100 . 
         [0214]    Step (b): inserting all or a portion of handpan-engagement-region  303  into cavity  110 , such that handpan-engagement-region  303  may removably support (and/or frictionally engage) handpan  100  so handpan  100  may be removably mounted in proximity to substrate  1001 . 
         [0215]    In some embodiments, the method may further comprise a step of using a landing strip embodiment (e.g.,  800  or  900 ), such that at least a portion of the landing strip may be disposed between a portion of handpan  100  and a portion of substrate  1001 . 
         [0216]    In some methods of using landing strip  900  with the hanger, landing strip  900  may be placed against substrate  1001 ; then substrate-mounting-region  302  may be placed against landing strip  900 , such that holes  907  and holes  307  align, then screws or the like may be inserted into the aligned holes to thus mount the hanger to substrate  1001 , with some portion of landing strip  900  disposed between substrate-mounting-region  302  and substrate  1001 ; and then cavity  110  may be inserted onto handpan-engagement-region  303 , such that the hanger now removably has mounted handpan  100  to substrate  1001 . Receiving holes in substrate  1001  may need to be drilled and/or bored prior to such receiving holes receiving the screws or the like. 
         [0217]    Note, as used herein, the phrase, “substrate-mounting-region is mounted to the substrate” or the like, may mean substrate-mounting-region  302  may be directly mounted to and in physical contact with substrate  1001 ; or that substrate-mounting-region  302  may be directly in physical contact with a portion of a landing strip (e.g., landing strip  900 ); such that this portion of the landing strip may be disposed between substrate-mounting-region  302  and substrate  1001 ; but that screws or the like passing through holes  907  and  307  may be received into receiving holes in substrate  1001 . That is, it is expressly contemplated that concepts of mounting substrate-mounting-region  302  to substrate  1001 , may in some embodiments, include portions of the landing strip disposed between substrate-mounting-region  302  and substrate  1001 . 
         [0218]    Note, as used herein, the word, “about,” particularly when used to refer to measurements and/or dimensions may mean to include a tolerance of plus or minus 10% of the applicable measurement and/or units noted. 
         [0219]    Embodiments of handpan hangers have been described, including systems comprising a hanger and a landing strip, as well as methods of using the hangers and/or the landing strips. The foregoing description of the various exemplary embodiments of the invention has been presented for the purposes of illustration and disclosure. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching without departing from the spirit of the invention. 
         [0220]    While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
