JP5420271B2 - Inner window with anti-scratch function at upper heel - Google Patents

Description

The present invention relates to a window frame and a fitting provided with a shoji that is supported by the window frame and can be opened and closed, and serves as a back plate for a shoji pulley mounting bracket that is exposed to the shoji and is opened and closed. The present invention relates to a preventer for preventing the upper end of the upper collar from being damaged when passing through the wire rope.

    In an inward window where the opening and closing means is performed by a wire rope operator, if the gap between the upper heel and the upper frame is wide, a concealable swing pulley and a concealable swing swing Roller shoji pulleys have been used. However, since the glass portion becomes wider and the gap becomes narrower and the pulley cannot be installed in the gap, both the frame pulley and the shoji pulley have to be provided as external windows.

Therefore, the conventionally used swinging type shoji pulley with roller cannot be used. As shown in FIG. 10, the roller 6 and the shoji pulley 3 are separately provided on one bracket 5, and the wire rope is opened in the middle. 8 has been regulated by an open damper (not shown) to a predetermined angle at which it does not contact the end of the upper collar. However, there are many requests from the need to fully open the window, and therefore the inventor further provided a fall window (see Patent Document 1) provided with a rotating roller for protecting the upper collar at the end of the upper collar. Successfully opened the window.

    However, compared to the conventional use of only a swinging-sliding pulley, the number of swinging pulleys, brackets, rollers, rotating rollers for protecting the upper end of the upper collar, and the number of parts are also increased, and the screws for fixing each are also increased. As a result, there has been a problem that the cost has been increased accordingly. The present invention has been provided for the purpose of solving such problems.

The present invention devised the back plate of the shoji mounting bracket, bent the end of the use part as the back plate into an L shape, and further bent the tip, so that the wire rope was the end of the upper arm when fully closed This problem has been solved by using a damage prevention tool having a predetermined height so as not to contact the part.
That is, the present invention provides a frame pulley and a shoji frame that are provided with the frame pulley and the shoji pulley exposed in the direction in which the shoji falls, and an opening / closing means is provided by the wire rope operator for attaching the exposed shoji pulley. The bracket is configured to be attached and fixed at a slightly higher level than the upper end on the inner side of the upper plate by the back plate, and in this back plate, the end of the back plate is bent into an L shape so as to extend toward the upper end on the outer side of the upper plate. It is extended, and its tip is bent , and the back plate is placed between the upper frame and the upper heel when the shoji is fully closed, and at the initial opening of the shoji and just before it is fully closed. without contacting the upper frame, Waiyaro the predetermined open from the angle to the angle of the full open external side upper end of the but wire rope contacts the processing unit the leading edge bent the shoji on stile of the shoji Flop is a window defeated in with protection scratch stile upper top, characterized by comprising configured so as not to contact.

The processing of the tip may be simply a bending process, or may be a shape in which a rotating roller is attached to the tip, and resistance is as much as possible when the end does not have an acute angle and contacts the wire rope. Smaller is better.

    The use of the product of the present invention has fewer parts than conventional ones, and the number of screws to be used is reduced, making inventory management easier, leading to cost reduction. Moreover, since this back plate has a simple shape, the cost per piece is low, and both the upper and lower ends of the shoji screen itself are not rubbed by the wire rope, thereby preventing damage.

    Embodiments of the present invention will be described based on examples. FIG. 1 is a perspective view showing the entire inside-down window provided with a back plate with a scratch-preventing function at the upper end of the upper eyelid in the shape shown in FIG. 6 of Embodiment 1 of the present invention, and FIG. Is a cross-sectional explanatory view showing the positional relationship between each part and a back plate with a function to prevent damage to the upper end of the upper collar when fully closed (A), halfway (B), fully opened (C), the upper collar end, and the wire rope FIG. 3 to FIG. 5 are enlarged cross-sectional views at positions A, B, and C, and FIGS. 6 and 7 are for preventing damage to the heel end of the present invention. FIG. 8 and FIG. 9 are enlarged cross-sectional views at positions A and C when using the back plate with an anti-damage function on the upper collar end of the shape shown in FIG. FIG. 10 shows an example of a conventional sample.

1 to 5, the configuration will be described. In the first embodiment, the shoji 4 is opened and closed by the wire rope operator 1 using the back plate 9 having the shape shown in FIG. The frame pulleys 2 and 2 and the shoji pulleys 3 and 3 are attached to the upper and lower armatures 7 and 7, respectively. The shoji pulleys 3 and 3 are attached to the Z-shaped brackets 5 and 5 attached to the shoji 4. The back plate 9 for attaching the brackets 5 and 5 to the shoji 4 is that of the first embodiment of the present invention, and is shown in FIG. The brackets 5 and 5 are attached and fixed slightly higher than the upper end portion in order to protect the upper end portion on the inner side of the upper collar. As shown at position A in FIG. 2, the back plate 9 is bent into an L shape, extended in the direction of the upper end on the outer side, and further bent at its tip, and when the shoji 4 is fully closed, the upper frame 11 and the upper collar 7, and does not come into contact with the upper frame 11 even when the shoji 4 is initially opened and just before it is closed. At the fully open position C, the wire rope 9 comes into contact with the bent end portion 10. It is comprised so that the edge part of the collar 7 may not be contacted.

Next, the operation will be described. In order to open the shoji 4 when fully closed, the winding lock of the wire rope 8 in the operator 1 is released by pushing the push button 12 provided on the operator 1, and both sides of the shoji are released. The shoji 4 is opened by the damper 13 provided in the door. 2A shows the fully closed position of the shoji 4, and the shoji 4 passes the B position and reaches the fully open position of the C position. This fully open position is determined by the fully open length of the dampers 13 provided at both ends of the shoji 4. The position indicated by the two-dot chain line in FIG. 2, that is, the two-dot chain line in FIG. 3 is the locus of the highest portion of the back plate 9 of the first embodiment, and is not related to the wire rope 8 at this A position. . Next, when the shoji 4 is gradually opened and reaches the position B in FIG. 2, the wire rope 8 contacts the upper end portion on the inner side of the upper collar by the tip bending portion 10 and the bracket 5 of the back plate 9 as shown in FIG. The wire rope 8 is not linearly tensioned and in contact with the frame pulley 2 and the tip bending portion 10 of the back plate 9 at the upper end portion on the outer side of the upper collar. Subsequently, the shoji 4 reaches the fully open position C. In FIG. 5, the upper end portion on the outer side of the upper collar is linearly stretched by the frame pulley 2 and the tip bending portion 10 of the back plate 9, and the distance is closer but not in contact with that in FIG. 4. The upper end on the inner side of the upper heel is also protected. Thus, the back plate 9 of the first embodiment of the present invention fixes the bracket 5 and becomes a back plate with a function of preventing damage to the upper end portion of the upper collar.

Next, the configuration of the second embodiment will be described. The back plate 9 of the second embodiment has the shape shown in FIG. 7, and the back plate 9 is bent into an L shape, extended, and further bent at its tip portion. When the sliding door 4 is opened and closed, it is attached without contacting the upper frame 11, and the mounting method is the same as in the first embodiment. Therefore, the description is omitted, and the situation is shown in FIGS. Since the operation is also the same, the description is omitted.
