PREFERRED EMBODIMENTS

As shown in FIG. 1, a shower door assembly is installed between walls 1, 2 and the ground 3 by a vertical side frame 40 and a horizontal track 50. A glass panel 60 is fixed by the vertical side frame 40 and the horizontal track 50. A shower door 70 can slide along the horizontal track 50 so as to be opened and closed. Connecting devices of an embodiment of this invention can be mounted at the positions A, B, C and D shown in FIG. 1.

The shower door assembly of this invention shown in FIG. 2 only shows the structures related to the concept of the invention, and other structures may be the same as or similar to the prior arts. As shown in FIG. 2, the shower door assembly comprises the horizontal track 50, the vertical side frame 40 and the fixed glass panel 60. The fixed glass panel 60 is mounted to the horizontal track 50 and the vertical side frame 40. A connecting device for connecting the horizontal track 50 and the vertical side frame 40 comprises a retaining member 10, a connecting member 20 and a locking member 30, wherein the retaining member may be mounted to the horizontal track 50 by a screw, the retaining member 10 and the locking member 30 may be hinged together by a pin.

As shown in FIG. 3, a rectangular chamber 55 is defined by a front wall 51, a rear wall 52, an upper wall 53 and a lower wall 54 of the horizontal track 50. A screw hole 56 is provided to be close to the lower wall 54. The front wall 51 is provided with a slide channel 57 along which the shower door 70 may slide. The lower wall 54 is provided with an installation channel 58 for installing the fixed glass panel 60, a door seal and the like.

For clear illustration, a portion of a side of the vertical side frame 40 shown in FIGS. 4 and 5 is cut off. As shown in FIGS. 4 and 5, the vertical side frame 40 comprises a bottom wall 41 and two side walls 42 extending in a direction perpendicular with the bottom wall 41, so that an inner space 43 is defined by the bottom wall 41 and the two side walls. An intermediate portion of the bottom wall 41 is concaved toward the inner space 43 to form an installation channel 44 for installing the fixed glass panel 60, a door seal and the like. An end of the bottom wall 41 is provided with an opening 45 which is also disposed on a bottom wall of the installation channel 44. A locking hole 46 acting as a position-limiting structure is provided below the opening 45.

As shown in FIGS. 6 and 7, the retaining member 10 comprises a retaining plate 11 provided with a lug 12 extending in a direction away from the horizontal track, a protrusion 13 with a cross section area slightly smaller than that of the chamber 55 is provided at an opposite side, so that the protrusion 13 can extend into the chamber 55 of the horizontal track 50, thereby helping to fix the retaining member 10. The lug 12 comprises a base part 16 and an extending part 18 which is provided with a hole 15. The retaining plate 11 is provided with a hole 14, so that the retaining member 10 can be fixed on an end face of the horizontal track 50 by a screw. A periphery of the retaining plate 11 is provided with a bent wall 17 extending towards the horizontal track 50, so that the end of the horizontal track 50 can be inserted into the bent wall 17, thereby protecting the end of the horizontal track and hiding a connection slit between the horizontal track and the retaining member.

As shown in FIGS. 8 and 9, the connecting member 20 includes a main body 21 and reinforcing plates 22 extending from the two sides of the main body 21 to reinforce the strength of the connecting member 20. The main body 21 is provided with an opening 23 from which the extending part 18 of the lug 12 may extend out. A hook 24 as a position-limiting structure is provided below the opening 23, and may extend into the locking hole 46 of the vertical side frame 40 to restrict movement of the connecting member 20 in a direction perpendicular with the horizontal track.

As shown in FIGS. 10 and 11, the locking member 30 includes a connecting portion 32 to be hinged with the lug 12, a hand-held part 33 for applying with a force to rotate the locking member 30, and an intermediate part 31 between the connecting portion 32 and the hand-held part 33. The connecting portion 32 comprises an opening, and a width of the opening is basically identical with that of the extending part 18, so that the extending part 18 is clamped within the connecting portion 32. A hole 34 is provided to the connecting portion 32 at a position corresponding to the hole 15. Hinging between the connecting portion 32 and the lug 12 can be realized by a pin passing through the holes 34 and 15. That is, the locking member 30 can rotate around the central axes of the holes 34 and 15. The locking member 30 includes an arc part 35 and a projection 36. A distance L1 from the arc part 35 to the central axis of the hole 34 is smaller than a distance L2 from the projection 36 to the central axis of the hole 34. When the arc part 35 faces the connecting member 20, the locking member 30 is in the unlocked position; and when the projection 36 faces the connecting member 20, the locking member 30 is in the locked position.

A process of connecting the horizontal track 50 and the vertical side frame 40 using the connecting device of this invention is shown in FIGS. 12-14. The retaining member 10 may be fixed to an end of the horizontal track 50 by a screw in advance. The end of the horizontal track 50 extends into the bent wall 17, so that the extending part 18 of the lug 12 passes through the opening 23 of the connecting member 20 to form a protruding part protruding from the opening 23, and is hinged with the connecting portion 32 of the locking member 30. When the arc part 35 of the connecting portion 32 of the locking member 30 faces the connecting member 20, the locking member 30 is in the unlocked position and may be generally parallel with the horizontal track 50. When assembling on site, the fixed glass panel 60 may be installed in the installation channel 44 of the vertical side frame 40. Then, the horizontal track 50 is moved towards the vertical side frame 40, so that the base part 16 of the lug 12 of the retaining member 10 enters into the installation channel 44 from an end of the vertical side frame 40. At the same time, the connecting member 20 and the extending part 18 of the lug 12 enter into the inner space 43 of the vertical side frame 40 along the opening 45, and the reinforcing plates 22 of the connecting member 20 are positioned at outer sides of the two side walls of the installation channel 44. Then, the locking member 30 is rotated to move towards the locked position. The projection 36 moves accordingly. When the projection 36 faces and presses against the connecting member 20, the connecting member 20 is pushed to abut against the bottom wall of the installation channel 44. At the same time, the horizontal track 50 is pulled inversely to approach the vertical side frame 40, and the hook 24 of the connecting member 20 enters into the locking hole 46 of the vertical side frame 40. Thus, the locking member 30 is in the locked position, is basically perpendicular with the horizontal track 50 and is positioned within the inner space 43, thereby completing the connection between the horizontal track 50 and the vertical side frame 40. Therefore, the connection process is simple and convenient and does not need other auxiliary tools.

When detaching the horizontal track 50 from the vertical side frame 40, the locking member 30 is reversely rotated such that the arc part 35 of the locking member 30 faces the connecting member 20; the connecting member 20 may move until the hook 24 releases from the locking hole 46; then, the connecting device may move along the opening 45 and may be detached from the end of the vertical side frame 40. In such a way, the horizontal track can be detached from the vertical side frame easily and quickly without any auxiliary tools.

In other embodiments, connection between the retaining member and the horizontal track may realized by buckling or the like. The position-limiting structures of the connecting member and the vertical side frame may adopt other manners. The hinging manner between the locking member and the lug may be replaced by other known manners. For example, the lug may have a hooked shape and may be hooked to a connecting rod inside the opening of the connecting portion.

The above is preferred embodiments of this embodiment. The design concept of this invention is limited thereto, and non-substantive modifications to this invention using this concept shall also fall into the protection scope of this invention.
