RELATED APPLICATIONS 
       [0001]    This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 62/213,306, entitled “BOSTON GATE,” and filed on Sep. 2, 2015, which is herein incorporated by reference in its entirety. 
     
    
     FIELD 
       [0002]    Embodiments herein relate to a safety gates which include a highly visible, color-coded locked/unlocked status indicator for use in household openings, such as doorways, to provide a barrier for a toddler or a small child, or for any other suitable use. 
       DISCUSSION OF THE RELATED ART 
       [0003]    Safety gates are used throughout households to prevent babies, children, and pets from accessing unsafe areas, such as landings, stairs, or non-childproofed furniture or rooms. These gates, provide lightweight, movable, and secure barriers to prevent children from accessing or entering potentially dangerous areas. 
         [0004]    One disadvantage of some safety gates is the requirement of two hands to open and close the gate. While this arrangement prevents unwanted openings from children, it also hinders adults who are often carrying children or household items in one of their hands. 
         [0005]    Another disadvantage of some safety gates is the uncertainty of knowing from a distance whether the gate is locked. Adults and older children, will sometimes accidentally close, but not lock, a toddler safety gate. Without the locking mechanism engaged, a toddler or small child may open the gate and access unsafe areas. 
       SUMMARY 
       [0006]    Embodiments disclosed herein may address one or more of these disadvantages by providing a safety gate that may be easily opened and closed with one hand, and/or that has a color-coded status indicator that shows someone within visual range whether the gate is properly locked.

     DETAILED DESCRIPTION 
       [0074]    Aspects of the invention are described herein with reference to certain illustrative embodiments and the figures. The illustrative embodiments described herein are not necessarily intended to show all aspects of the invention, but rather are used to describe a few illustrative embodiments. Thus, aspects of the invention are not intended to be construed narrowly in view of the illustrative embodiments. In addition, it should be understood that aspects of the invention may be used alone or in any suitable combination with other aspects of the invention. 
         [0075]    Embodiments disclosed herein relate to a safety gate for use in household openings, such as doorways, hallways, and stair landings to provide a safe barrier for a toddler or a small child. 
         [0076]    The gate assembly  1  comprises a lightweight frame  2  with a moveable door barrier  3 . The frame  2  includes two spaced apart lateral frame members  4  and  5 , joined together at their respective bases  6  and  7  to a base frame member  8 . The frame members  4 ,  5 , and  8  define an opening for the door barrier  3 . 
         [0077]    The door barrier  3  is hingedly movable forward and backward relative to the frame  2 . The door barrier  3  may hingedly move to one of two open positions relative to the frame  2 : the door barrier  3  may move forward relative to the frame  2  to an angle substantially 90 to 120 degrees, or the door barrier  3  may move backward relative to the frame  2  to an angle substantially 90 to 120 degrees. In either open position, passage through the door barrier  3  is possible. 
         [0078]    The closed position of the door  3  is substantially parallel relative to the frame  2 . In the closed position, passage through the door barrier  3  is prevented. 
         [0079]    As may be seen in  FIG. 7 , The frame  2  may be positioned within a doorway  9  or wall opening with removable pressure mounts  10 . The pressure mounts can be quickly released to move the gate assembly  1  to another desired location in the household. 
         [0080]    The door barrier  3  comprises a panel  11  having a base member  12 , a top member  13 , and a plurality of struts  14  at spaced intervals between frame members  4  and  5 . The door barrier  3  is hingedly joined to frame member  5  via a top hinge  15  and a bottom hinge  16 . 
         [0081]    The top hinge  15  comprises a top hinge panel  17  with a channel  18  that receives and holds one end  19  of top member  13  of panel  11 . The top hinge panel  17  comprises a rotatable front housing  20  and a fixed rear housing  21 . The rotatable front housing  20  and the fixed rear housing  21  are connected with a top hinge pin  22  inserted into a lower hinge pin  23 . The rear face  24  of the rotatable front housing  20  has a substantially complementary shape to the front face  25  of fixed rear housing  21 . The top hinge pin  22 , lower hinge pin  23 , and the complementary shape of the rear face  24  to the front face  25  permit the top hinge panel  17  and the door barrier  3  to fully rotate in either direction, backward and forward, with respect to the frame  2  along the axis of the top hinge pin  22  and the lower hinge pin  23 . 
         [0082]    The fixed rear housing  21  of the top hinge panel  17  further comprises a base member  26  for insertion into channel  27  on top end  28  of frame member  4 . Base member  27  and holds the rear housing  21  in a fixed position as the front housing  20  rotates relative to the frame  2 . 
         [0083]    The bottom hinge  16  of the door barrier  3  comprises a bottom hinge housing  29  with a channel  30  that receives and holds one end  31  of base member  12  of panel  11 . The bottom hinge housing  29  comprises a bottom hinge pin  32  that inserts into channel  33  in base frame member  8 . The bottom hinge pin  32  and the complementary shape of channel  33  permit the bottom hinge housing  29  and the door barrier  3  to fully rotate in either direction, backward and forward, with respect to the frame  2  along the axis of bottom hinge pin  32 . This bottom rotational axis is substantially the same rotational axis of the top hinge pin  22  and the lower hinge pin  23  of the top hinge panel  17 . 
         [0084]    The bottom hinge housing  29  and one end  31  of base member  12  of panel  11  also extend into an automatic gate closure stop  34 . Automatic gate closure stop  34  may include a compressible resilient material that comprises a bottom recess  35  which rests on the top surface  36  of base frame member  8 . Bottom recess  35  may be substantially elongate with a longitudinal axis that is substantially parallel to base frame member  8 . Automatic gate closure stop  34  also may include a narrow top recess  37  for removably holding bottom hinge housing  29  when the door barrier  3  is in the closed position. Top recess  37  may be substantially elongate with a longitudinal axis that is substantially parallel to base frame member  8 . Top recess  37  may have two sidewalls  38  composed of compressible resilient material and a channel  39  for receiving and holding bottom hinge pin  32  that inserts into channel  33  in base frame member  8 . Top recess  37  also may comprise a series of lateral protrusions  40  composed of compressible resilient material extending from sidewalls  38 . 
         [0085]    The non-hinged, swinging side of the door barrier  3  may include a top latch panel  41  with a channel  42  that receives and holds one end  43  of top member  13  of panel  11 . 
         [0086]    The top latch panel  41  may include a moveable front housing  44  and a fixed rear housing  45 . The moveable front housing  44  and a fixed rear housing  45  are connected with an internal latch  46  that inserted into a rear channel  47  (see, for example,  FIG. 20 ) on moveable front housing  44  and a front channel  48  (see, for example,  FIG. 19 ) on fixed rear housing  45 . The moveable front housing  44  comprises a channel  49  that receives and holds one of the door barrier struts  14 . 
         [0087]    The fixed rear housing  45  of the top latch panel  41  may further comprise a base member  50  for insertion into channel  51  of frame member  5 . Base member  50  and holds the rear housing  45  in a fixed position as the moveable front housing  44  is unlatched from frame  2 . 
         [0088]    The moveable front housing  44  comprises visual openings  52  on one or both sides of the housing. Visual openings  52  substantially align with the internal latch  46 . In the closed, latched position of the door barrier  3 , a first end  53  of the internal latch  46  is contained within channel  48  of fixed rear housing  45 . In this latched position, the portions of sidewalls  54  that are farther away from fixed rear housing  45  are visible through openings  52 . In  FIG. 19 , this portion is on the right side of sidewall  54 . The portion that is visible when the door barrier  3  is latched may have a first color, such as green, or any other suitable color. These portions of the sidewalls  54  of the internal latch  46  are visible, from a distance, through visual openings  52  on one or both sides of the moveable front housing  44 . Thus, with the door barrier  3  in the latched position, with internal latch  46  within channel  48  of the fixed rear housing  45 , a green color is visible on one or both sides of moveable front housing  44  through visual openings  52 . This green color indicates that the gate  1  is locked, as the first end  53  of the internal latch  46  is within channel  48  of the fixed rear housing  45 . This indication can be viewed from a distance. 
         [0089]    The moveable front housing  44  further comprises a top button  55  that contains an internal lever  56  which engages the internal latch  46  to move it out of channel  48  and fixed rear housing  45 . To open the door barrier  3 , a user grips moveable front housing  44  and slides button  55  away from fixed rear housing  45  using his or her fingers. Once the internal latch  46  is engaged by internal level  56  and removed from rear housing  45 , the moveable front housing  44  is disengaged from the rear fixed housing  45 , and the door barrier  3  may begin rotation in either direction relative to frame  2 . 
         [0090]    Once the internal latch  46  is in an unlatched position, the user lifts moveable front housing  44  using the same hand, thereby lifting automatic gate closure stop  34  out of the top recess  37  away from the sidewalls  38  and lateral protrusions  40 . With automatic gate closure stop  34  clear of top recess  37 , door barrier  3  may be moved to an open position. This movement permits the bottom hinge housing  29 , and the door barrier  3 , to fully rotate in either direction, backward and forward, with respect to the frame  2  along the axis of bottom hinge pin  32 . 
         [0091]    As door barrier  3  is opened, the bottom hinge pin  32  rotates within channel  33  of base frame member  8  and channel  39  of top recess  37  of the automatic gate closure stop  34 . This bottom rotational axis is substantially the same rotational axis of the top hinge pin  22  and the lower hinge pin  23  of the top hinge panel  17 . 
         [0092]    In this unlocked position, different portion of the sidewalls  54  of the internal latch  46  are visible through openings  52 . For example, the portions that are closer to the rear fixed housing  45  are visible through openings  52 . In the embodiment shown in  FIG. 19 , the left side of sidewall  54  would be visible through opening  52  when the internal latch is in the unlocked position. These portions of the sidewalls  52  have a second color that is different from the first color. For example, the second color may be red or any other suitable color. These portions of the sidewalls  54  of the internal latch  46  are visible through visual openings  52  on either side of the moveable front housing  44 . Thus, with the door barrier  3  in the unlatched position, and with internal latch  46  no longer within channel  48  of the fixed rear housing  45 , a red color (or other suitable color) is visible on either side of moveable front housing  44  through visual openings  52 . This red color indicates, from a distance, that the gate  1  is unlocked, as the internal latch  46  is not contained within channel  48  of the fixed rear housing  45 . 
         [0093]    From the door barrier  3  open position of the gate assembly  1 , the automatic gate closure stop  34  compresses against the compressible resilient material of the sidewalls  38  and the lateral protrusions  40 . This resilient force automatically pulls the automatic gate closure stop  34  and the attached the door barrier  3 , bottom hinge housing  29 , attached end  31  of base member  12  back toward top recess  37 . This pulling rotates bottom hinge pin  32  within channel  33  of base frame member  8  and channel  39  of top recess  41 . Once the door barrier  3  is proximate to the closing position, the automatic gate closure stop  34  is substantially aligned and drops down between sidewalls  38  and protrusions  40 . This dropping down of automatic gate closure stop  34  substantially aligns door barrier  3  with respect to frame  2  and moves the gate assembly  1  into a locked position. 
         [0094]    With the door barrier  3  in the locked position, the first color (e.g., green) of the internal latch  46  is visible on either side of moveable front housing  44  through visual openings  52 . This green color indicates, from a distance, that the gate  1  is locked, as the first end  53  of the internal latch  46  is within channel  48  of the fixed rear housing  45 . 
         [0095]    The bottom second end  57  of base member  12  of panel  11  is free to rotate with door barrier  3 . The gate assembly  1  comprises a gate stop  58  attached to frame  4 . The gate stop  58  comprises an a flat extension  59  for engaging a second end  57  of the base member  12  and preventing further rotation of panel  11  and door barrier  3 . In some embodiments of the present disclosure, the gate stop  58  is rotatable to stop the door barrier  3  in either direction for placement of the gate in either forward or backward orientation in any doorway  9 . 
         [0096]    Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description and drawings are by way of example only.
