     FIELD OF THE INVENTION 
     The invention relates to a fitting for shower partition parts made of a flat material such as, glass, plastic or similar. More particularly, the present invention relates to a flat shower partition assembly having an innovative hinge mechanism, a stationary wall and a door pivotally, wherein the gap between the pivoting door and a stationary partition glass wall or an ordinary wall is sealed. 
     BACKGROUND OF THE INVENTION AND PRIOR ART 
     Bathtubs and showers stalls often include a partition to prevent shower water from spraying onto the surrounds of the bathtub/stall. Typically, at least a portion of the partition includes a pivoting door. 
     Often, the partition includes a stationary wall and a door pivotally attached thereto. In some embodiments there may be more than one stationary wall and more than one door. It would be advantageous for the pivotable door, when closed, to be situated such that the pivotable door panel is flush with the adjacent stationary portions of the partition. However, there exist a sealing problem between the stationary wall and the pivoting door. 
     In other embodiments the pivoting door is attached to an ordinary wall, wherein the ordinary wall may by any type of wall, including a glass wall, wherein in the closed state the pivotable door panel is substantially perpendicular to the ordinary wall, and wherein a gap is formed between the pivoting door and the wall. It would be advantageous for the pivotable door to be generally situated perpendicular to the wall. However, there exist a sealing problem between the wall and the pivoting door. 
     There is therefore a need for and it would be advantageous to have a shower partition assembly that includes a stationary wall and a door pivotally attached thereto, wherein the gap between the stationary wall and the pivoting door is sealed, and wherein the pivoting door may pivot in both directions, with respect to the stationary wall, typically, up to 90° in each direction. 
     SUMMARY OF THE INVENTION 
     The principal intentions of the present invention include providing a shower partition assembly that includes an innovative hinge mechanism, a stationary wall and a door pivotally attached thereto, wherein the pivotable door panel is flush with the stationary portions of the partition, and wherein the gap between the stationary wall and the pivoting door is sealed, and wherein the pivoting door may pivot in both directions, with respect to the stationary wall, typically, up to 90° in each direction. 
     According to the teachings of the present invention, there is provided a shower partition assembly, having at least one stationary wall and at least one pivotable door, wherein the stationary wall and the pivotable door are pivotally interconnected by at least one hinge mechanism, wherein the at least one hinge mechanism includes a first-section-mechanism having a shaft-hosting member, securely attached to the at least one stationary wall, and a second-section-mechanism that includes a pivoting-enabling-member. The pivoting-enabling-member includes a base section, securely attached to the at least one pivotable door, and a U-shaped arm-section. The U-shaped arm-section includes a base-arm, an embracing-arm and a bridge, interconnecting the base-arm and the embracing-arm, wherein an embracing-arm-gap is formed between the base-arm and the embracing-arm. 
     The shaft-hosting member and the pivoting-enabling-member are pivotally connected by a shaft, disposed proximal to the open end of said embracing-arm, to thereby facilitate pivotal motion of the at least one pivotable door about the shaft, with respect to the at least one stationary wall, when the at least one pivotable door is pushed or pulled. 
     When the at least one hinge mechanisms is in a closed-state, a wall-vertical edge of the at least one stationary wall is disposed substantially parallel to a door-vertical edge of the at least one pivotable door, forming a substantially parallel wall-door-gap, having a preconfigured width. 
     When the at least one pivotable door is opened in a first direction ( 37 , see  FIGS. 3 and 7 ) towards a first-open-state, the embracing-arm pivots about the shaft, and the bridge and embracing-arm move towards the wall-vertical edge, until the wall-vertical edge is accommodated inside the embracing-arm-gap. 
     When the at least one pivotable door is opened in the second direction ( 35 , see  FIGS. 4 and 6 ) towards a second-open-state, the embracing-arm pivots about the shaft and said bridge and the embracing-arm move away from the wall-vertical edge and towards the shaft-hosting member that serves as a stopper for the pivoting motion. The embracing-arm-gap facilitates the opening and closing of the at least one pivotable door in both directions with respect to the at least one stationary wall. 
     Preferably, the shower partition assembly further includes a sealer, that in some embodiments, is mounted over the open wall-vertical edge of the at least one stationary wall, wherein the sealer is preconfigured to seal the wall-door-gap when the at least one hinge mechanisms is in a closed-state. Optionally, in some other embodiments, the sealer is mounted over the open door-vertical edge of the at least one pivotable door and still is preconfigured to seal the wall-door-gap when the at least one hinge mechanisms is in a closed-state. Optionally, the sealer is made of elastic materials, wherein the sealer portion extending away from the wall-vertical edge is larger than the width of the wall-door-gap, by a preconfigured amount. 
     It should be noted that the at least one hinge mechanisms may be securely attached on either side of a stationary wall that is paired with a pivotable door. 
     In some embodiments of the present invention, the first-section-mechanism is securely attached to the pivotable door, while the second-section-mechanism is securely attached to the stationary wall. In variations of such embodiments, the least one stationary wall is an ordinary wall, wherein the ordinary wall may be any type of wall, including a glass wall, wherein in the closed state the pivotable door panel is substantially perpendicular to the ordinary wall, and wherein the wall-vertical edge is a virtual vertical line that is most proximal to the door-vertical edge, and wherein, in the closed state, the pivotable door is substantially perpendicular to the ordinary wall.

The following described attachment mechanisms are given by way of example only and other attachment mechanisms known in the art may be used within the scope of the present invention. It should be noted that in other embodiments of the present invention, first-section-mechanism  102  is securely attached to the pivotable door  30  and second-section-mechanism  104  is securely attached the stationary wall  20 . 
     Boreholes  22  are formed in preconfigured locations of stationary wall  20 , proximal to vertical edge  28  of stationary wall  20 . Hinge mechanism  100  further includes a wall clamping member  120 , having boreholes  122  formed in preconfigured locations of clamping member  120 , spaced apart to respectively overlap with boreholes  22  of stationary wall  20 . Boreholes  112  are also formed in preconfigured locations of shaft-hosting member  110 , spaced apart to also respectively overlap with boreholes  22  of stationary wall  20 . 
     In one embodiment of the present invention, the wall attaching mechanism are screws ( 170 ,  180 ) having threads that match threads that are formed inside boreholes  112  of shaft-hosting member  110 . When assembling, shaft-hosting member  110  is securely placed on one side of wall  20  (typically, with no limitation, adjacent to the external surface of wall  20 , with respect to the location of the shower stall), such that boreholes  112  of shaft-hosting member  110  overlap with boreholes  22  of stationary wall  20 . Symmetrically, clamping member  120  is placed on the other of wall  20  (typically, with no limitation, adjacent to the internal surface of wall  20 , with respect to the location of the shower stall), such that boreholes  122  of clamping member  120  overlap with boreholes  22  of stationary wall  20 . Then, screws  170  are inserted into respective boreholes  122  and boreholes  22 , and screwed into threaded boreholes  112  of shaft-hosting member  110  to secure first-section-mechanism  102  onto wall  20 .

Symmetrically, clamping member  140  is placed on the other side of door  20  (typically, with no limitation, adjacent to the internal surface of pivotable door  30 , with respect to the location of the shower stall), such that boreholes  142  of clamping member  140  overlap with boreholes  32  of stationary pivotable door  30 . Then, screws  180  are inserted into respective boreholes  142  and boreholes  32 , and screwed into threaded boreholes  132  of pivoting-enabling-member  130  to secure second-section-mechanism  104  onto pivotable door  30 . 
     Shaft-hosting member  110  has a generally elongated U-shape, wherein the flat external surface  111  of the U-shape base is the surface that, when assembled, is secured to wall  20 . Arms  118  of the U-shaped body of shaft-hosting member  110  extend away from external surface  111 , wherein a gap  116  (see  FIGS. 8 and 9 ) is formed between arms  118  and wherein gap  116  facilitates fittingly accommodating pivoting-enabling-member  130 . Boreholes  114  are formed in arms  118  at preconfigured locations of shaft-hosting member  110 , proximal to the edge of the side of shaft-hosting member  110  that is proximal to vertical edge  28  of wall  20 . 
     Pivoting-enabling-member  130  includes a base section  138  (see  FIGS. 8 and 9 ) and a U-shaped arm-section  139 . Base-section  138  includes a flat external surface  131  (see  FIG. 9 ) that, when assembled, is secured to pivotable door  30 . Arm-section  139  (see  FIGS. 8 and 9 ) extends away from base-section  138 , towards and beyond vertical edge  28  of wall  20  (when assembled), wherein the base of the U-shaped arm-section  139  is distally situated, with respect to pivotable door  30  and wall  20 , when pivotable door  30  is in a closed state, as shown in  FIG. 5   a , having a sealer  160  mounted over vertical edge  28  of wall  20 . In  FIG. 5   b , sealer  160  has been removed for illustrative purposes only. Without a sealer  160 , a wall-door-gap  165  must be formed between vertical edge  28  of wall  20  and vertical edge  38  of pivotable door  30 , which edges are disposed substantially parallel. 
     An embracing-arm-gap  136 , formed between the arms (base section  138 , base-arm  133  and embracing-arm  137 ) of the generally U-shape arm-section  139 , facilitates opening and closing of pivotable door  30  in both directions with respect to wall  20  (see  FIGS. 6 and 7 ), while sealing the substantially parallel wall-door-gap ( 165 ) between vertical edge  28  of wall  20  and vertical edge  38  of pivotable door  30 , in a closed state. 
     Boreholes  114  are formed in arms  118  at preconfigured locations of shaft-hosting member  110 , proximal to the edge of the side of shaft-hosting member  110  that is proximal to vertical edge  28  of wall  20 . Preferably, bearing-cylinders  152  are inserted in each borehole  114  in the respective arm  118 . A hollow cylinder  134  is formed through arm-section  139 , proximal to the typically round tip of embracing-arm  137  of arm-section  139 . 
     To complete the assembly of hinge mechanism  100 , a fitted shaft  150  is inserted through bearing-cylinders  152  and through hollow cylinder  134 , facilitating pivotal motion of second-section-mechanism  104  with respect to first-section-mechanism  102 . Shaft  150  may be a one-part or two parts shaft. Shaft  150  may be secured to embracing-embracing-arm  137  of arm-section  139  by various means. For example, by forcefully inserting shaft  150  into hollow cylinder  134 , or by an securing screw (not shown) screwed through the wall of the tip of embracing-arm  137  of arm-section  139 , wherein the tip of the securing screw is forced into a slit  154  formed generally at the center of  150 . Another option is to have a shaft  150  with a wider top end (top—with respect to the operative orientation of shaft  150 . 
     To facilitate sealing wall-door-gap  165  between vertical edge  28  (see  FIGS. 3 and 4 ) of wall  20  and vertical edge  38  of pivotable door  30 , a sealer  160  is mounted over vertical edge  28  of wall  20 . Typically, with no limitation, sealer  160  is removably mounted over vertical edge  28  of wall  20 . U-shape arm-section  139  facilitates opening and closing of pivotable door  30  in both directions with respect to wall  20  (see  FIGS. 6 and 7 ), while sealer  160  remains unharmed on vertical edge  28  of wall  20 . 
     When pivotable door  30  is in a closed state, as shown in  FIG. 5   a , vertical edge  38  of pivotable door  30  presses against sealer  160 , to thereby seal wall-door-gap  165  formed between vertical edge  28  of wall  20  and vertical edge  38  of pivotable door  30 . 
     When pivotable door  30  is opened in a second direction  35  towards a second-open-state (typically, with no limitation, outwardly, as shown in  FIGS. 4 and 6 ), embracing-arm  137  of arm-section  139  pivots about shaft  150  inside gap  116  of shaft-hosting member  110 , wherein vertical edge  38  of pivotable door  30  moves away from embracing-arm-gap  136 , and bridge  135  and embracing-arm  137  move away from wall-vertical edge  38  and towards shaft-hosting member  210  that serves as a stopper for the pivoting motion. 
     When pivotable door  30  is opened in a first direction  37  towards a first-open-state (typically, with no limitation, inwardly), as shown in  FIGS. 3 and 7 , embracing-arm  137  of arm-section  139  pivots about shaft  150  away from gap  116  of shaft-hosting member  110 , wherein vertical edge  38  of pivotable door  30  moves away from edge  28  of wall  20  towards a wall clamping member  120 , and wherein vertical edge  28  of wall  20 , including sealer  160 , are accommodated inside embracing-arm-gap  136  of the U-shape arm-section  139 .

It was further described that hinge mechanism  100  includes a first-section-mechanism  102  and a second-section-mechanism  104 , wherein first-section-mechanism  102  is securely attached to stationary wall  20 , and a second-section-mechanism  104  is securely attached to pivotable door  30 . For the sake of clarity, it should be noted that first-section-mechanism  102  may be securely attached to pivotable door  30 , while a second-section-mechanism  104  is securely attached to stationary wall  20 . It should be further clarify that the at least one hinge mechanisms  100  may be securely attached to either side of a set of stationary wall  20  and pivotable door  30 . 
     Typically, with no limitation two or three hinge mechanisms  100  are pivotally attaching second-section-mechanism  104  to first-section-mechanism  102 . 
     In variations of the present invention sealer  160  is attached to vertical edge  38  of pivotable door  30 , rather than to vertical edge  28  of wall  20 . 
     In variations of the present invention second-section-mechanism  104  is attached to pivotable door  30  by other conventional attaching means, and not by screws  180 . Similarly, first-section-mechanism  102  may be attached to wall  20  by other conventional attaching means, and not by screws  170 . 
     Optionally, a gasket is placed between clamping member  120  and stationary wall  20 ; between clamping member  140  and pivotable door  30 ; shaft-hosting member  110  and stationary wall  20 ; and/or between pivoting-enabling-member  130  and pivotable door  30 .

Thereby, when pivotable door  30  is pivoted, pivoting-enabling-member  230  pivots about shaft  250 . 
     Boreholes  22  are formed in preconfigured locations of pivotable door  30 , proximal to vertical edge  38  of pivotable door  30 . Hinge mechanism  200  further includes a door clamping member  220 , for securing second-section-mechanism  202  onto pivotable door  30 . In one embodiment, clamping member  220  includes boreholes  222  formed in preconfigured locations of clamping member  220 , spaced apart to respectively overlap with boreholes  32  of pivotable door  30 . Boreholes  212  are also formed in preconfigured locations of shaft-hosting member  210 , spaced apart also to respectively overlap with boreholes  32  of pivotable door  30 . 
     In one embodiment of the present invention, the door attaching mechanism are screws  270  having threads that match threads that are formed inside boreholes  212  of shaft-hosting member  210 . When assembling second-section-mechanism  202 , shaft-hosting member  210  is securely placed on one side of pivotable door  30 , such that boreholes  212  of shaft-hosting member  210  overlap with boreholes  32  of pivotable door  30 . Symmetrically, clamping member  220  is placed on the other of pivotable door  30 , such that boreholes  222  of clamping member  220  overlap with boreholes  32  of pivotable door  30 . Then, screws  270  are inserted into respective boreholes  222  and boreholes  32 , and screwed into threaded boreholes  212  of shaft-hosting member  210  to secure second-section-mechanism  202  onto pivotable door  30 . 
     When assembling first-section-mechanism  204 , pivoting-enabling-member  230  is securely attached to bathroom wall  40  at a preconfigured location, using for example boreholes  232 . 
     Shaft-hosting member  210  has a generally elongated U-shape, wherein the flat external surface  211  of the U-shape base is the surface that, when assembled, is secured to pivotable door  30 . Arms  218  of the U-shaped body of shaft-hosting member  210  extend away from external surface  211 , wherein a gap  216  (see  FIGS. 16 and 17 ) is formed between arms  218  and wherein gap  216  facilitates fittingly accommodating pivoting-enabling-member  230 . Boreholes  214  are formed in arms  218  at preconfigured locations of shaft-hosting member  210 , proximal to the edge of the side of shaft-hosting member  210  that is proximal to vertical edge  38  of pivotable door  30 . 
     Pivoting-enabling-member  230  includes a base section  238  (see  FIGS. 16 and 17 ) and a wall-arm-section  233 . Base-section  238  includes a flat external surface  231  (see  FIG. 17 ) that, when assembled, is adjacently secured to bathroom wall  40 . Wall-arm-section  233  includes an embracing-arm  237  and a bridge  235 . Bridge  235  extends generally perpendicular and away from base-section  238 , towards and beyond vertical edge  38  of pivotable door  30  (when assembled). Embracing-arm  237  extends away from base-section  238 , embracing pivotable door  30  proximal to vertical edge  38  of pivotable door  30  (when assembled), and substantially parallel to flat external surface  231  of base-section  238 . 
     An embracing-arm-gap  236  is formed between embracing-arm  237  and base-section  238 , facilitates opening and closing of pivotable door  30  in both directions with respect to ordinary wall  40  (see  FIGS. 10 and 11 ), while sealing the substantially parallel wall-door-gap ( 265 ) between ordinary wall  40  and vertical edge  38  of pivotable door  30 , as shown in  FIG. 5   a , with sealer  260  mounted over vertical edge  38  of pivotable door  30 . Parallel wall-door-gap  265 , formed between ordinary wall  40  and vertical edge  38  of pivotable door  30  varies in size as pivotable door  30 , wherein sealed  260  is designed to seal the minimally-sized wall-door-gap  265  formed between a virtual vertical line that is most proximal to door-vertical edge  38 , when pivotable door  30  is perpendicular to ordinary wall  40 , pivotable door  30  being in a closed state. In  FIG. 5   b , sealer  260  has been removed for illustrative purposes only. Without a sealer  260 , a wall-door-gap  265  must be formed between the surface of ordinary wall  40  and vertical edge  38  of pivotable door  30 , which edges are disposed substantially parallel. 
     Boreholes  214  are formed in arms  218  at preconfigured locations of shaft-hosting member  210 , proximal to the edge of the side of shaft-hosting member  210  that is proximal to vertical edge  38  of pivotable door  30 . Preferably, bearing-cylinders  252  are inserted in each borehole  214  in the respective arm  218 . A hollow cylinder  234  is formed through embracing-arm  237 , proximal to the typically round tip of embracing-arm  237 . 
     To complete the assembly of hinge mechanism  200 , a fitted shaft  250  is inserted through bearing-cylinders  252  and through hollow cylinder  234 , facilitating pivotal motion of second-section-mechanism  202  with respect to first-section-mechanism  204 . Shaft  250  may be a one-part or two parts shaft. Shaft  250  may be secured to embracing-arm  237  of bridge  239  by various means. For example, by forcefully inserting shaft  250  into hollow cylinder  234 , or by an securing screw (not shown) screwed through the wall of the tip of embracing-arm  237 , wherein the tip of the securing screw is forced into a slit  254  formed generally at the center of  250 . Another option is to have a shaft  250  with a wider top end (top—with respect to the operative orientation of shaft  250 . 
     To facilitate sealing wall-door-gap  265  between ordinary wall  40  and vertical edge  38  of pivotable door  30 , a sealer  260  is mounted over vertical edge  38  of pivotable door  30 . Pivoting-enabling-member  230  facilitates opening and closing of pivotable door  30  in both directions with respect to ordinary wall  40  (see  FIGS. 10 and 11 ), while sealer  260  remains unharmed on vertical edge  38  of pivotable door  30 . 
     When pivotable door  30  is in a closed state, as shown in  FIGS. 12 ,  13  and  5   a , the surface of bathroom ordinary wall  40  presses against sealer  260 , to thereby seal wall-door-gap  265  formed between ordinary wall  40  and vertical edge  38  of pivotable door  30 . 
     When pivotable door  30  is opened in a first direction  37  towards a first-open-state, as shown in  FIG. 10 , embracing-arm  237  pivots about shaft  250  away from gap  216  of shaft-hosting member  210 , wherein vertical edge  38  of pivotable door  30 , carrying sealer  260 , moves away from ordinary wall  40  into embracing-arm-gap  236 , wherein pivoting-enabling-member  230  accommodates vertical edge  38  of pivotable door  30  inside embracing-arm-gap  236 , including sealer  260 . 
     When pivotable door  30  is opened in direction  35  towards a second-open-state, as shown in  FIG. 11 , embracing-arm  237  pivots about shaft  250  inside gap  216  of shaft-hosting member  210 , wherein vertical edge  38  of pivotable door  30  moves away from embracing-arm-gap  236 , and bridge  235  and embracing-arm  237  move away from wall-vertical edge  38  and towards shaft-hosting member  210  that serves as a stopper for the pivoting motion. 
     Typically, with no limitation one, two or three hinge mechanisms  200  are pivotally attaching first-section-mechanism  204  to second-section-mechanism  202 . 
     In variations of the present invention second-section-mechanism  202  may be attached to wall  20  by other conventional attaching means, and not by screws  270 . 
     Optionally, a gasket is placed between clamping member  220  and pivotable door  30  and/or between shaft-hosting member  210  and ordinary wall  40 . 
     The invention being thus described in terms of embodiments and examples, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the claims.
