In order to achieve a waterproofing effect, thebottom jamb member 15 has aninner water baffle 151 which is twice as high as aninner rail 152 that, in turn, which is higher than anouter rail 153. A drawback results in that theouter window panel 13 must be loaded or unloaded before the inner panel 12 due to the higherinner water baffle 151. Thus, the operator has to work from the inside of the window through a limited passage opening of the window frame, due to the presence of theinner window panel 13. This results in inconveniences and can increase the risk of dropping of the window panel from the operator's hands. - The main aim of the present invention is to provide a sliding-type window frame which permits a window panel assembly to be installed conveniently while maintaining a good waterproofing effect.
- According to this invention, the sliding-type window frame includes a jamb frame assembly with a top jamb member, a bottom jamb member, and two upright side jamb members. The top jamb member has a top channel body with a space for receiving a top end of a window panel assembly and which has two opposites ends connected respectively to the side jamb members, and a sash cap plate which is mounted movably to the top channel body inside the space and which extends between the side jamb members. The sash cap plate has at least one top track member to slidably engage the top end of the window panel assembly when the sash cap plate is in a first position. The sash cap plate is movable upward from the first position to a second position so as to move the top track member away from the top end of the window panel assembly, thereby facilitating loading and unloading of the window panel assembly into and from the jamb frame assembly.
