CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/210,307, filed Aug. 26, 2015, which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to headache-relieving devices and methods, and more particularly, to a headache-relieving device which is attached to the hand and can apply pressure to a pressure point on the hand between the thumb and index finger of a user to relieve headaches. 
       BACKGROUND OF THE INVENTION 
       [0003]    A headache, or cephalalgia, is pain in the head or neck that can be a symptom of any of various conditions of the head and neck. Headaches can be caused by disturbance of pain-sensitive structures around the brain, due for instance to fatigue, sleep deprivation, stress, the effects of medications and recreational drugs, viral infections, common colds, head injury, rapid ingestion of cold foods or beverages, dental work or sinus issues. Headaches are one of the most commonly experienced of all types of physical discomforts. 
         [0004]    In the medical field, a number of different classification systems for headaches are currently used. For instance, headaches are broadly classified as “primary” or “secondary”. Primary headaches are benign, recurrent headaches which are not caused by underlying disease or structural problems. A migraine headache is a type of primary headache. Primary headaches may cause significant daily pain and disability. Secondary headaches are caused by an underlying disease such as an infection, head injury, vascular disorders, brain bleed or tumors. 
         [0005]    Treatment of headaches commonly involves the use of painkillers. However, many potential users of painkillers may be allergic to the painkillers and thus, unable to use them for relief. Furthermore, long-term use of some painkillers may have deleterious effects on health. 
         [0006]    Accordingly, there is an established need for a headache-relieving device which can be drug-free and is easily and conveniently usable by a person in order to relieve their headache. 
       SUMMARY OF THE INVENTION 
       [0007]    The present invention is directed to a hand-pressing, headache-relieving device which is worn on a hand of a user and can apply pressure on a pressure point on the hand to relieve headaches. The device provides an effective, convenient, easy-to-use and drug-free way of treating headaches. The headache-relieving device includes a device body having a first side, a second side and, preferably, a connecting portion connecting the second side to the first side. A hand space is formed between the first side and the second side. A pressing element is provided on the second side. The headache-relieving device can be applied to the hand of a user who suffers from headache by inserting the hand of the user in the hand space. The pressing element can be positioned over a pressure point typically between the thumb and index finger on the user&#39;s hand and, preferably, can be tightened against the pressure point to relieve the user&#39;s headache. 
         [0008]    In a first implementation of the invention, a headache-relieving device includes a device body and a pressing element. The device body has a first side and a second side arranged in a spaced-apart relationship with one another, thereby delimiting a hand space therebetween. The pressing element, in turn, is provided on the second side of the device body and protrudes into the hand space of the device body. The pressing element is configured to apply pressure against a pressure point on a user&#39;s hand positioned in the hand space. 
         [0009]    In a second aspect, the device body can be flexible and the hand space is size adjustable, to facilitate lacing the device body on a hand. In some embodiments, the device body can be elastically deformable, such as to recover a more opened position after ceasing a compression force which brings the first and second sides of the device body together to adjust to the hand. In other embodiments, the device body can be plastically deformable, to remain opened or closed as set by the user. 
         [0010]    In another aspect, the device can further include at least one strap connecting the first side and the second side of the device body, to secure the device body to the user&#39;s hand. 
         [0011]    In another aspect, the connecting strap can include two opposite ends, each end attached to a corresponding one of the first side and second side of the device body. In some embodiments, at least one of the ends is non-disconnectably attached to the corresponding one of the first side and second side of the device body. In other embodiments, at least one of the ends is disconnectably attached to the corresponding one of the first side and second side of the device body. 
         [0012]    In yet another aspect, the at least one strap can extend through registering first and second strap slots in the first side and the second side of the device body, respectively, reducing the footprint of the device on the user&#39;s hand. 
         [0013]    In another aspect, the device body can further include a connecting portion connected to the first side and the second side of the device body forming a C-shape, to embrace a side of the user&#39;s hand and more snugly adjust to the hand to guarantee pressure is exerted on the pressure point. In some embodiments, the first side, second side and connecting portion are formed into a single-piece unit. At least one length-adjustable connecting member (e.g., a strap) can connect the second side to the first side of the C-shaped device body. 
         [0014]    In another aspect, the pressing element can be adjustable to vary a protrusion depth of the pressing element into the hand space and thus vary the pressure of the pressing element against the pressure point in the user&#39;s hand. In some embodiments, the pressing element can be threaded into a pressing element opening on the second side of the device body, and the pressing element can be adjusted by selectively threading or unthreading the pressing element into or from the pressing element opening. Optionally, the pressing element can include a pressing element knob arranged on an outer side of the second side of the device body, and a pressing element shaft extending from the pressing element knob and through the pressing element opening in the second side of the device body. A tip of the pressing element shaft can protrude into the hand space to apply pressure against the pressure point on the user&#39;s hand positioned in the hand space. The tip can be rounded. 
         [0015]    These and other objects, features, and advantages of the present invention will become more readily apparent from the attached drawings and the detailed description of the preferred embodiments, which follow.

         [0029]    Shown throughout the figures, the present invention is directed toward a headache-relieving device which is attached to a user&#39;s hand and can apply pressure to a pressure point on the hand between the thumb and index finger of the user to relieve headaches. The headache-relieving device does not require drugs to relieve a person&#39;s headaches and can thus provide a drug-free and risk-free treatment of headaches. In addition, the user can normally operate and function with his hand while treating their headache. 
         [0030]    Referring initially to  FIG. 1 , a headache-relieving device  100  is illustrated in accordance with an exemplary embodiment of the present invention. The headache-relieving device  100  includes a device body  110 . The device body  110  may be fabricated of neoprene, plastic, rubber and/or other preferably flexible material. As illustrated in  FIG. 4 , the device body  110  may be generally C-shaped in side view and may include a first side  112 , a second side  114  and a generally curved and flexible or adjustable connecting portion  116  which connects the second side  114  to the first side  112  thereby forming a C-shape. Preferably, as shown, the first side  112 , second side  114  and connecting portion  116  are formed into a single-piece unit, such as made of plastic, rubber or the like and manufactured by injection molding. The first side  112  and second side  114  are spaced apart, a hand space  118  being delimited by and formed between the first side  112  and the second side  114 . The hand space  118  is adjustable, such as by the connecting portion  116  being flexible and adjustable to allow varying the distance between the first side  112  and the second side  114 . Alternatively or additionally, the first side  112  and second side  114  can be flexible and/or flexibly attached to the connecting portion  116 . In general, any part of, or the entire C-shaped device body  110  can be flexible to allow for an adjustment of the hand space  118  to a user&#39;s hand. 
         [0031]    In some embodiments, at least one connecting member may further connect the second side  114  to the first side  112  of the device body  110 . The connecting member may include at least one connecting strap  140 . In some embodiments, such as the illustrated embodiment, a pair of connecting straps  140  may connect the second side  114  to the first side  112  on respective sides of the connecting portion  116 . 
         [0032]    As best shown in  FIG. 2 , each connecting strap  140  may have a fixed end portion  142  which is permanently or non-disconnectably attached to one of the first side  112  and second side  114 , and an elongated, flexible connecting strap body  144  which extends from the fixed end portion  142 . At least one pair of a first strap slot  120  and a second strap slot  122  may extend through the first side  112  and the second side  114 , respectively. Accordingly, the fixed end portion  142  of the connecting strap  140  may extend through the first strap slot  120  in the first side  112  or, in alternative embodiments, through the second strap slot  122  in the second side  114 ; in the present embodiment, more specifically, the fixed end portion  142  of the connecting strap  140  is looped through the first strap slot  120  and is permanently or non-disconnectably attached to the first side  112 . The connecting strap body  144  of the connecting strap  140 , in turn, may extend through a remaining, registering second strap slot  122  or first strap slot  120  in the other side, i.e. the second side  114  or first side  112  of the device body  110 ; for instance, in the present embodiment, the connecting strap body  144  extends through the second strap slot  122  in the second side  114  of the device body  110  on the same side of the C-shaped device body  110  on which the fixed end portion  142  is attached. The connecting strap body  144  may be looped around and attached to the fixed end portion  142  of the connecting strap  140  and/or to the remainder of the connecting strap body  144  via hook and loop fasteners, snaps and/or other disconnectably-attachable attachment mechanism known by those skilled in the art. 
         [0033]    In some embodiments, the connecting strap body  144  of at least one connecting strap  140  may be length-adjustable using buckles, hook and loop fasteners and/or alternative adjusting techniques known by those skilled in the art, to allow the user to adjust the tightness of the connecting strap  140  to his/her desire. In some embodiments, the connecting strap body  144  of at least one connecting strap  140  can be elastic, such as made of or comprising rubber, an elastic fabric, or the like, allowing the connecting strap  140  to automatically adjust to the user&#39;s hand. 
         [0034]    As shown in  FIGS. 1 and 2 , a pressing element  150  may be provided on the second side  114  of the device body  110 . As best shown in  FIGS. 3 and 4 , the pressing element  150  can protrude from an inner surface  124  into the hand space  118 . Preferably, the pressing element  150  is movable with respect to the second side  114  in order to allow for adjustment of the protruding depth from the inner surface  124 . For instance, the pressing element  150  depicted herein is threaded to the second side  114  and can be threaded or unthreaded by the user in order to vary the depth of protrusion of the pressing element  150  into the hand space  118 . 
         [0035]    As illustrated in  FIG. 6 , in some embodiments, the pressing element  150  may include a pressing element knob  152 . A pressing element shaft  154  may extend from the pressing element knob  152 . Pressing element threads  156  may be provided on an exterior surface of the pressing element shaft  154 . As illustrated in  FIGS. 6 and 9 , the distal end of the pressing element shaft  154  may be rounded or blunted. A pressing element opening  126  may extend through the second side  114  in communication with the hand space  118 . In some embodiments, a pressing element collar  128  may protrude from the second side  114  in concentric relationship to the pressing element opening  126 . Pressing element opening threads  130  may be provided on an interior surface of the pressing element opening  126  and/or the pressing element collar  128 . In the present embodiment, both the pressing element opening  126  and the pressing element collar  128  are threaded. Accordingly, the pressing element shaft  154  may threadably engage the pressing element opening  126  and the pressing element collar  128 . The pressing element knob  152  can be selectively rotated in a clockwise or counterclockwise direction to advance the pressing element shaft  154  into the hand space  118  and in an opposite counterclockwise or clockwise direction, respectively, to retract the pressing element shaft  154  from the hand space  118  for purposes which will be hereinafter described. 
         [0036]    As illustrated in  FIGS. 7 through 9 , in typical application, the headache-relieving device  100  is placed on the hand  300  of a user who is suffering from a headache. In some embodiments, the flexible device body  110  can be slightly opened to facilitate insertion and fitting onto the hand  300 . The connecting strap body  144  of each connecting strap  140  may be selectively length-adjusted to facilitate movement of the second side  114  away from the first side  112  and selective enlargement of the hand space  118  for placement of the user&#39;s hand  300  in the hand space  118 . The hand  300  is placed in the hand space  118  between the first side  112  and the second side  114  of the device body  110 , with the tip of the pressing element shaft  154  of the pressing element  150  positioned in registration with a pressure point  310  between the thumb  320  and index finger  330  on the hand  300 . In some embodiments, once set place, the device body  110  may be elastically deformable, and allowed to recover a more closed position to snugly but comfortably adjust to the hand  300 ; in other embodiments, the device body  110  may be plastically deformable and the user may deform the device body  110  to a desired adjustment on the hand  300 ; in further alternative embodiments, the device body  110  may not be flexible or deformable. Once the device body  110  is fitted onto the hand  300  so that the tip of the pressing element shaft  154  is positioned in registration with the pressure point  310 , the connecting straps  140  may then be tightened and/or fastened typically according to the preference of the user, to secure the C-shaped device body  110  onto the hand  300  and maintain the tip of the pressing element shaft  154  in registration with the pressure point  310 . The pressing element knob  152  may then be rotated (typically in a clockwise direction) to advance the pressing element shaft  154  against the pressure point  310  and cause the pressing element shaft  154  to press the pressure point  310  as shown in  FIG. 9 . The tightness of the pressing element shaft  154  against the pressure point  310  may be selectively varied by rotation of the pressing element knob  152 , in accordance with user preference, the magnitude of the headache, or any applicable factor. The headache-relieving device  100  can be maintained in place on the hand  300 , or intermittently removed from the hand  300  and re-applied, as necessary, to reduce the magnitude of the headache or eliminate the headache. 
         [0037]    Referring next to  FIG. 10 , an alternative illustrative embodiment of the headache-relieving device is generally indicated by reference numeral  200 . Like features of the headache-relieving device  200  and the headache-relieving device  100  ( FIGS. 1 through 9 ) are numbered the same except preceded by the numeral ‘2’. 
         [0038]    The headache-relieving device  200  shown in  FIG. 10  includes a first connecting strap  240  which is the same as or similar to that of the headache-relieving device  100 . The headache-relieving device  200  includes a second connecting strap  260  having a first fixed end portion  262  connected to the corresponding first strap slot  220  which extends through the first side  212  of the device body  210 , and an elongated connecting strap body  264  extending from the fixed end portion  262 . Unlike the first embodiment, however, the second connecting strap  260  further includes an opposite second fixed end portion  266  which extends through the second strap slot  222  in the second side  214  of the device body  210  and is permanently or fixedly formed in the connecting strap body  264  and permanently affixed to the second side  214 , similarly to the first fixed end portion  262 . In some embodiments, the connecting strap body  264  of the second connecting strap  260  may be selectively length-adjustable and/or elastic. In other embodiments, the length of the connecting strap body  264  may be fixed. 
         [0039]    Further alternative embodiments are contemplated in which both ends of one or both connecting straps are non-permanently attached to the device body, and can be disconnected from the device body. In some embodiments, one or both connecting straps are entirely removable from the device body, for instance to facilitate washing the connecting straps and/or the device body, or to allow replacing either one of the connecting straps or the device body. 
         [0040]    With continued reference to  FIG. 10 , application of the headache-relieving device  200  may be as was heretofore described with respect to the headache-relieving device  100  of  FIGS. 1-9 . The connecting strap body  244  of the first connecting strap  240  may be selectively length-adjustable and/or detachable with respect to the second side  214  to facilitate selective enlargement of the hand space  218  for placement of the user&#39;s hand  300  in the hand space  218 . The pressing element  250  is then adjusted onto the pressure point  310  by selective user operation of the pressing element knob  252  with the other hand (not shown), or by a person assisting the user. 
         [0041]    Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
