Description

ROLLER ASSEMBLY FOR WINDOW AND METHOD OF USING SAME BACKGROUND OF THE INVENTION [001] Glazing frames that are made to be moved along installation frames, e.g. for windows or doors, typically require involving means for decreasing the friction developing between the glazing frame and the installation frame. Such friction increases as the weight of the window increases and as the contact area between those frame increases. In order to ease the movement of windows along their installation frame, a well-known solution uses rollers that are installed on the bottom side of the glazing frame such that the weight of the window leans on rollers. The rollers are made to roll on a mating part of the installation frame. Some prior art solutions teach use of roller with flat face that are made to run on a mating flat face of a respective window installation frame. Such solutions suffer of drawbacks, such as low rolling factor (i.e. extended roller-frame friction factor), and tendency of accumulating of dirt on the rolling surface. All known solutions demonstrate use of rollers that are installed on the bottom side of the glazing frame prior to the insertion of the window into its installation frame. Such solutions suffer of a common drawback – in order to enable insertion of the window into its installation frame a large installation space needs to be reserved so that the total height of the window, with its glazing frame and the rollers installed on the bottom side of the glazing frame will have spared installation free space to allow insertion of the window into its frame, as demonstrated in Fig. 1A, which depicts a schematic cross section of window 102 and window installation frame 104. id="p-2" id="p-2" id="p-2" id="p-2"

[002] Window 102 comprises window frame 102B having top element 102BT and bottom element 102BB within which window glazing 102A is installed. On the bottom side of window bottom element 102BB roller 102BR is installed or disposed. In View "A" of Fig. 1A window 102 is shown disposed within a mating window installation frame 104. As shown, roller 102BR is leaning on the bottom element 104B of installation frame 104 and the upper side of window 102 is kept within upper element 104T of installation frame 104. View "B" of Fig. 1A depicts how window 102 may be inserted into installation frame 104. First window 102 is tilted sideway (so that its top element 102B is moved to the right of the page) and then top element 102B is inserted into upper element 104T of installation frame 104and is lifted up until the lower end of roller 102BR may pass over the edge of bottom element 104B and then bottom element 102BB of window 102 may with roller 102BR may be inserted into bottom element 104B of installation frame 104. id="p-3" id="p-3" id="p-3" id="p-3"

[003] As seen in Fig. 1A, view "A" in order to enable this method of insertion of window 102 into installation frame 104 window 102 must have enough space, denoted 104FS (free space), left within upper element 104T to enable roller 102BR to pass over the edge of bottom element 104B of installation frame 104. The magnitude of the required free space is dictated by the dimension 104AH – the height of the side face of bottom element 104B of installation frame 104. It will be noted that when all sides of installation frame 104 are made of the same profile (which is the common case), the magnitude 104AH substantially equals to magnitude 104FS, which in turn dictates even greater magnitude of 104FS due to the extended height 104AH. It is noted that roller 102BR adds to the basic dimension 102basic measured from external face of top element 102BT to the external face of bottom element 102BB. id="p-4" id="p-4" id="p-4" id="p-4"

[004] Some similar known solutions spare a space for the rollers within the bottom element of the window frame. Reference is made now to Fig. 1B, which schematically demonstrates a cross section of a window assembly 150 with rollers installed within its window frame 170. Window assembly comprises window frame 152 which comprises net-frame part 1adapted to accommodate glazing 156 and roller hide part 158 comprising (in this crosssection view) bottom part 158B and top part 158T. bottom part 158B is designed to accommodate roller 150R. The height of bottom part 158B is dictated by the size of roller 150R and the height of top part 158T is equal to that of bottom part 158B. as seen in Fig. 1B, the net size required to provide a supporting frame for the glazing, i.e. part 154, is extended by bottom part 158B and top part 158T, which leads to a bulky window frame, due to the inclusion of roller 150R inside the window frame profile. id="p-5" id="p-5" id="p-5" id="p-5"

[005] There is a need for toller assembly and method of using that assembly, that will allow keeping the side faces of upper element 104T and bottom element 104B of a window installation (Fig. 1A) or the height of window frame elements 158B and 158T (Fig. 1B) as low as possible, while maintaining the option of installing and removing window 1into/from installation frame 104 when needed.
