DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring to FIG. 1 and FIG. 4, there is shown a portion of a door (20) with a glass frame (10) embedded therein, and the glass frame (10) is a two-part glass frame constituted by two frame parts (10A and 10B) to sandwich a piece of glass (11) between inner sides (30A) of the parts (10A and 10B) of the frame (10).
As shown in FIG. 4, inner edges (30A) of respective parts (10A and 10B) cooperate with each other to sandwich between them a piece of glass (11).
Outer edges (30B) of respective parts (10A and 10B) cooperate with each other to mount onto the edges of an opening of the door (20).
3a Preferably, the frame (10) is generally rectangular in shape and the shape of the frame (10) corresponds to that of the opening on the door (20).
An embodiment of coupler (100) is shown in FIGS. 4 to 6B. The coupler (100) includes a first part (101) and a second part (102) coupled to one another through an extension part (103). The first and second parts (101 and 102) both comprise an engagement means in the form of lock member (200 or 300).
In the preferred embodiment, the first part (101) has one end integrally formed with the frame parts (10B) while the second part (102) has one end integrally formed with the frame part (10A). The orientation of the first and second parts (101 and 102) on the respective frame parts (10B and 10A) are the same with the lock members (200 and 300) both facing away from the glass (11) and towards the door (20).
Alternately, the first part (101) may have its lock member (200) faces a direction opposite that of the lock member (300) of the second part (102).
In the preferred embodiment, the first and second parts (101 and 102) are substantially the same in construction; both have a generally rectangular body supporting the lock member (200 or 300). The lock member (200 or 300) has a base (201 or 301) and projection (203 or 303) sandwiching a detent (202 or 302). It also has a further projection (204 or 304) extending from a free end of the first and second parts (101 and 102). These features together define an engagement surface of the lock member (200 or 300).
The base (201 or 301), the projection (203 or 303) and the detent (202 or 302) are useful in and mainly for preventing movement of the first and second parts (101 and 102) relative to the extension part (103) along axis X which is substantially perpendicular to a neutral axis Z of the frame (10). The further projection (204) is useful in and mainly for preventing movement of the first and second parts (101 and 102) relative to the extension part (103) along axis Y which is substantially perpendicular to the neutral axis Z and the axis X.
In a preferred embodiment, there is at least one coupler on each side of the frame (10) for coupling the frame parts (10A and 10B). Once coupling has been established by each of the couplers (100), relative movement of the first and second parts (101 and 102) relative to the extension part (103) along axis Z will not be an issue. Of course, the first and second parts (101 and 102) and the extension (103) may have features that cooperate and prevent such relative movement. For example they may be a pair of protrusions extending from the free end in a direction generally perpendicular to and sandwiching the projection (204 or 304).
The extension part (103) is generally rectangular with two opposite coupling ends provided with a first retaining member (103A) and a second retaining member (103B). In the preferred embodiment, the first retaining member (103A) and the second retaining member (103B) are structurally different making them distinguishable from one another. The first retaining member (103A) includes a plate (401) extending from one of the coupling end and a tongue (402) extending perpendicular to the plate (401) at its lower end. This tongue (402) is insertable into the detent (202) of the first part (101). The projection (203) is retained in the space (403) defined by the tongue (402) and lower end of the extension part (103).
At the lower end of the extension part (103), there is a groove (404) digging into the lower end. This groove (404) accommodates the further projection (204) of the first part (101). The plate (401), the tongue (402), the space (403) and the groove (404) together defines a retaining surface of the first retaining member (103A).
To save costs and to minimize weight, the main body of the extension part (103) is hollow. Adjacent the other coupling end, on which the second retaining member (103B) is formed, there is a partitioning wall (405) that helps to maintain the shape of the extension part (103). The second retaining member (103B) has two oppositely extending legs (406 and 407). Each of the legs (406 and 407) has a foot part (406A
and 407A) that extends generally or substantially perpendicular to the legs (406 and 407). These foot parts (406A and 407A) abut an inner side of the frame part (10A) and fit inside grooves (50 and 51) of the frame part (10A) to lock themselves in. This prevents movement of the first part (101) in the direction along the axis Y
relative to the extension part (103). The leg (407) has a flange (407B) that abuts the projection (303) of the second part (102) which prevents the movement of the second part (102) in the direction along axis X relative to the extension part (103).
Preferably, the foot parts (406A and 407A) are vertically displaced.
In an alternative embodiment, the coupling ends of the extension part (103) have the same structure. In a further embodiment, the second part (102) does not have a base (301) or a projection (304).
As shown in FIGS. 6A and 6B, when assembled, the tongue (402) of the extension part (103) is inserted into the detent (202) and the space (403) accommodates the projection (203). The projection (204) of the first part (101) is inserted into the groove (404). The flange (407B) is accommodated in the detent (302) , and abuts the projection (303) to lock the first part (101) and the extension part (103) together. Also the foot parts (406A and 407A) are inserted into the grooves (50 and 51) which helps locks the extension part (103) to the second part (102).
The invention has been given by way of example only, and various other modifications of and/or alterations to the described embodiment may be made by persons skilled in the art without departing from the scope of the invention as specified in the appended claims.
FIG. 6A is a perspective view of the coupler in FIGS. 4 and 5; and FIG. 6B is an exploded perspective view of the coupler in FIGS. 4 and 5.

As shown in FIG. 4, inner edges (30A) of respective parts (10A and 10B) cooperate with each other to sandwich between them a piece of glass (11).
Outer edges (30B) of respective parts (10A and 10B) cooperate with each other to mount onto the edges of an opening of the door (20).
3a Preferably, the frame (10) is generally rectangular in shape and the shape of the frame (10) corresponds to that of the opening on the door (20).
An embodiment of coupler (100) is shown in FIGS. 4 to 6B. The coupler (100) includes a first part (101) and a second part (102) coupled to one another through an extension part (103). The first and second parts (101 and 102) both comprise an engagement means in the form of lock member (200 or 300).
In the preferred embodiment, the first part (101) has one end integrally formed with the frame parts (10B) while the second part (102) has one end integrally formed with the frame part (10A). The orientation of the first and second parts (101 and 102) on the respective frame parts (10B and 10A) are the same with the lock members (200 and 300) both facing away from the glass (11) and towards the door (20).
Alternately, the first part (101) may have its lock member (200) faces a direction opposite that of the lock member (300) of the second part (102).
In the preferred embodiment, the first and second parts (101 and 102) are substantially the same in construction; both have a generally rectangular body supporting the lock member (200 or 300). The lock member (200 or 300) has a base (201 or 301) and projection (203 or 303) sandwiching a detent (202 or 302). It also has a further projection (204 or 304) extending from a free end of the first and second parts (101 and 102). These features together define an engagement surface of the lock member (200 or 300).
The base (201 or 301), the projection (203 or 303) and the detent (202 or 302) are useful in and mainly for preventing movement of the first and second parts (101 and 102) relative to the extension part (103) along axis X which is substantially perpendicular to a neutral axis Z of the frame (10). The further projection (204) is useful in and mainly for preventing movement of the first and second parts (101 and 102) relative to the extension part (103) along axis Y which is substantially perpendicular to the neutral axis Z and the axis X.
In a preferred embodiment, there is at least one coupler on each side of the frame (10) for coupling the frame parts (10A and 10B). Once coupling has been established by each of the couplers (100), relative movement of the first and second parts (101 and 102) relative to the extension part (103) along axis Z will not be an issue. Of course, the first and second parts (101 and 102) and the extension (103) may have features that cooperate and prevent such relative movement. For example they may be a pair of protrusions extending from the free end in a direction generally perpendicular to and sandwiching the projection (204 or 304).
The extension part (103) is generally rectangular with two opposite coupling ends provided with a first retaining member (103A) and a second retaining member (103B). In the preferred embodiment, the first retaining member (103A) and the second retaining member (103B) are structurally different making them distinguishable from one another. The first retaining member (103A) includes a plate (401) extending from one of the coupling end and a tongue (402) extending perpendicular to the plate (401) at its lower end. This tongue (402) is insertable into the detent (202) of the first part (101). The projection (203) is retained in the space (403) defined by the tongue (402) and lower end of the extension part (103).
At the lower end of the extension part (103), there is a groove (404) digging into the lower end. This groove (404) accommodates the further projection (204) of the first part (101). The plate (401), the tongue (402), the space (403) and the groove (404) together defines a retaining surface of the first retaining member (103A).
To save costs and to minimize weight, the main body of the extension part (103) is hollow. Adjacent the other coupling end, on which the second retaining member (103B) is formed, there is a partitioning wall (405) that helps to maintain the shape of the extension part (103). The second retaining member (103B) has two oppositely extending legs (406 and 407). Each of the legs (406 and 407) has a foot part (406A
and 407A) that extends generally or substantially perpendicular to the legs (406 and 407). These foot parts (406A and 407A) abut an inner side of the frame part (10A) and fit inside grooves (50 and 51) of the frame part (10A) to lock themselves in. This prevents movement of the first part (101) in the direction along the axis Y
relative to the extension part (103). The leg (407) has a flange (407B) that abuts the projection (303) of the second part (102) which prevents the movement of the second part (102) in the direction along axis X relative to the extension part (103).
Preferably, the foot parts (406A and 407A) are vertically displaced.
In an alternative embodiment, the coupling ends of the extension part (103) have the same structure. In a further embodiment, the second part (102) does not have a base (301) or a projection (304).
