The present invention relates to a sliding door assembly having a plurality of roller assemblies attached to a lower horizontal member to perform sliding movement along horizontal lines.

Conventional conventional roller assemblies are used on horizontal paths with cross-sectional topped paths so that the roller wheels are in contact with the horizontal base, or horizontal paths with elongated vertical flutes on the top surface. It is supposed to turn in contact. Roller assemblies of the type that can be used on both tracks are also known, in which the circumference of the roller wheels extends out of the roller frame, turning in contact with the horizontal base or the vertical plot. However, such roller assemblies have not been very satisfactory. This is because when the roller assembly is used on a track with an elongated vertical flue, the roller wheels are likely to move sideways while exiting the vertical plot while the door assembly is sliding along the track. Another drawback with conventional roller assemblies is their complexity because they use relatively many parts.

It is an object of the present invention to provide a sliding door assembly with a roller assembly, to safely guide the sliding motion of the door assembly, whether using an open passageway track or on a track with an elongated vertical flute. .

Another object of the present invention is to provide a roller assembly for use in the door assembly, to minimize the number of parts, to secure the structure, to reduce the manufacturing cost and to easily attach to the door assembly.

Other advantages and features of the present invention will become apparent from the following description with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention, but the present invention is not limited thereto.

The sliding door assembly 10 is partially shown in FIG. 1, which is installed in an outer window frame (not shown) to open and close horizontally. The sliding door assembly 10 here is a screen chassis. The screen chassis 10 includes a rectangular frame 11 having a lower horizontal member 12, a screen plate 13 installed in the frame 11, and a plurality of rollers installed at regular intervals along the length of the base plate 12. Assembly 14 or the like. In the accompanying drawings, one of the roller assemblies 14 is shown away from the base 12.

The body of the bottom stand 112 has a channel shape with a cross section down, and is made of synthetic resin. The base 12 has a pair of arms 15 and 15 spaced parallel to each other, and a C-shaped base 16 having an angled cross section connects the upper edges of these arms 15 and 15 to each other. . The underlayment 12 also has an integral channel portion 17 extending integrally along the base 16. The channel portion 17 supports to receive the lower edge of the screen plate 13. A plurality of pairs of cuts 18 and 18 having a U-shaped inverted shape are formed through the arms 15 and 15, so that several openings 19 are spaced apart from the bottom plate 12 by a predetermined distance. Formed.

Each of the roller assemblies 14 has a hollow frame 20 having a rectangular horizontal cross section, and the frame 20 has a pair of rectangular side walls 21, 21 and two ends thereof having a rectangular shape parallel to each other. It consists of a pair of end walls (22), (22) connecting the. Each of the end walls 22, 22 has a U-shaped cutout 23 formed by a pair of parallel side edges 23a, 23a and end edges 23b therebetween. The width between the side walls 21, 21 in the roller frame 20 is slightly larger than the width between both arms 15, 15 in the underlayment 12. The length of each of the side walls 21 and 21 is approximately the same as the length of the cut 18. The pair of supports 24, 24 extend integrally from the end walls 22, 22 in opposite directions. Each of the supports 24, 24 consists of a pair of laterally spaced rectangular portions 24a, 24a, the distal end of each rectangular portion being thickened to form a contact 24b. One edge of each of the rectangular portions 24a and 24a lies flush with the edge 23b of the cutout 23, and the other edge is cut off from the end wall 22 of the edge 23b. It is arrange | positioned in the middle with the edge on the opposite side to the part 23.

In each of the roller assemblies 14, roller wheels 25 are installed on the pins 26 between the side walls 21 and 21 so as to rotate. The pin 26 has a structure in which both ends of the rivet are axially connected to the side walls 21 and 21, and the roller wheel 25 has a circumferential groove 27 formed therein. As best shown in grips 2, 3 and 4, the circumference of the roller wheel 25 is one of the end edges 23b of the cutout 23 and one of the side walls 21, 21 in the roller frame 20. It is arranged in the middle with the edges 28 and 28. The circumference of the roller wheel 25 also extends out beyond the other edges 29, 29 of the side walls 21, 21. The bottom of the circumferential groove 27 is also arranged out of the plane formed by the end edge 23b.

When installing the screen chassis 10 in the outer window frame 30 (FIG. 5) with a horizontal threshold 31 of open channeled tracks 32, each of the roller assemblies 14 is recessed. We install from bottom to each). At this time, each of the side walls (21), (21) is fitted tightly to the corresponding cut portion 18, the end walls (22), 22 are both vertical edges of the cut portion 18 at the edges (22a), (22a) 22a, 22a, and each edge 28 of the side walls 21, 21 is in contact with the horizontal edge of the cut 18, which is formed as a distal edge of the passage-shaped base 16. Let's go. To attach each of the roller assemblies 14 to the base plate 12, press each pair of rectangular portions 24a, 24a with finger pressure to close the gap, and then between the arms 15, 15 on both sides. Push in. The thick contact portions 24b and 24b then come into frictional contact with the arms 15 and 15. Finally, when the screen chassis 10 is installed in the outer frame 30, each roller wheel 25 is turned in contact with the horizontal base 32a of the channel-shaped track 32. By making the width of each roller frame 20 only slightly smaller than the width of the track 32, the screen chassis 10 is minimized to move sideways with respect to the plane of the outer frame 30, and thus the sliding of the chassis 10 It makes movement easier and also kills the rattling noise while the chassis 10 is sliding.

When installing the screen 10 on the outer window frame 33 (FIG. 6) having an elongated vertical flue or horizontal threshold 34 of rails 35, each of the roller assemblies 14 is provided with a recessed portion ( 19) is generally the same as the above-described method for the outer window frame 30, except that the respective edges 29 of the side walls 21, 21 have a horizontal edge with the cut 18. Contact. Next, when the screen 10 is installed on the outer window frame 33, the roller wheel 25 is placed on the vertical flange 35. Since the pair of cutouts 23, 23 on both end walls 22, 22 accommodate the vertical flue 35, the roller wheel 25 moves sideways to exit the flute 35. It interferes with the exit, thus safely guiding the sliding movement of the screen chassis.

Those skilled in the art can make various minor changes, but such changes are also within the scope of the present invention.
