Description

[Detailed description of the invention] [Industrial application field] This invention is based on the idea that the operating rod for operating multiple window fittings (hereinafter referred to as mounting pins) provided around the window sill is attached to the corner of the window sill. This article relates to corner fittings for window shoji frames that are connected together.

[Conventional technology]

BACKGROUND OF THE INVENTION Traditionally, there have been commonly known windows that are both casement windows and fold-down windows.

In this type of window, the mounting pins for opening windows and the mounting pins for folding windows slide in the circumferential direction of the window shoji stile on the vertical stile and horizontal stile of the window, and are attached to the pin receivers of the opening frame so that they can be engaged and removed. The mounting pins for casement windows and the mounting pins for folding windows are connected to handles via operating rods that are slidably mounted in the vertical stile and horizontal stile in the circumferential direction thereof. When opening and closing the window, the handle is turned to slide the mounting pins for casement windows and the mounting pins for folding windows in the circumferential direction of the window shoji frame, and selectively engage the pin receivers on the opening frame to open the window. It is opened and closed as a window or a folding window.

[The problem that the idea aims to solve]

By the way, in this type of window, the operating levers installed in the left and right vertical frames and the operating levers installed in the upper and lower frames are connected at each corner of the window, for example, by a wire.

The wire is passed through a guide groove formed in a roughly arc shape along the corner of the window shoji frame in a guide member, so that the wire can smoothly slide around the corner of the window (for example, −
(See Figure 2 of Publication No. 34274).

However, with this configuration, the wire slides around the corner of the window shoji frame due to friction between the wire and the guide groove, especially as the wire becomes rusted by rainwater over the years. In many cases, this was not possible, and the disadvantage was that the force could not be effectively transmitted to the corner of the window shoji stile of the operating rod.

This invention was proposed to solve the above-mentioned conventional problems, and it not only makes it possible to transmit the force of the operating rod extremely smoothly at the corner of the window shoji frame, but also makes it easy and inexpensive to manufacture. The purpose of this invention is to provide corner furniture for window shoji frames that is possible.

[Means to solve the problem]

In this invention, a guide member 16 is provided at each corner of a window shoji frame, a substantially L-shaped guide groove 19 is provided in the guide member 16 along the corner part of the window shoji frame, and the guide groove 19 is provided with a substantially L-shaped guide groove 19. A bendable and deformable slide member 18 is inserted therethrough, and operating rods 13, 1 are provided at both ends of the slide member 18 to operate a plurality of window metal fittings provided at the corners of the window shoji frame.
In the corner metal fittings 15 of the window shoji frame connecting the 4, the guide groove 1 on which the slide member 18 slides.
Curved laces 1 on the inside and outside of the corners of 9
7a, and a large number of rollers 17b are arranged on the opposite surface thereof.
The above object is achieved by having the rolling receiver 17 rotatably buried therein.

〔Example〕

This invention will be explained below based on an embodiment shown in the drawings.A mounting pin 4 for a casement window and a mounting pin 5 for a folding window are attached to the vertical stile 2 and lower stile 3 on one side of the window 1 in the longitudinal direction of each stile. It is attached to pin receivers 9 and 10 attached to the vertical frame 7 and lower frame 8 of the opening frame 6 so as to be able to engage and detach from each other, and one corner of the vertical stile 2 and the lower stile 3 has a Mounting pin that has the functions of both mounting pins 4 and 5 (figure omitted)
is attached, and this attachment pin is engaged with a pin receiver 12 at a corner of the opening frame.

Further, operating rods 13 and 14 are inserted into the left and right vertical stiles 2, 2 and the lower stile 3 so as to be slidable in the longitudinal direction of each stile. The operating rods 13 and 14 are connected in an arc shape by corner fittings 15 at each corner of the vertical stile 2 and the lower stile 3, and the mounting pins 4 and 5 are connected to the handle 11 by the operating rods 13 and 14. There is.

In this configuration, by turning the handle 11, the attachment pin 4 and the pin receiver 9 and the attachment pin 5 and the pin receiver 10 can be freely engaged and disengaged.

The corner fitting 15 is composed of a guide member 16, rolling receivers 17, 17 such as needle bearings or ball bearings, and a slide member 18.

The guide member 16 is formed of metal or synthetic resin into a substantially L-shape along the corner of the window sill, and has a substantially L-shaped guide groove 19 continuous along the longitudinal direction formed on the side thereof.

The corner portion of the guide groove 19 has a certain curvature, and the rolling receiver 1 is formed on the outside and inside of the corner.
7, 17 are attached. The rolling receiver 17 has substantially curved races 17a arranged on the inner and outer sides of the corner portions, and a plurality of rollers 17b are rotatably embedded in the opposing inner and outer surfaces of the races 17a.

Further, the guide member 16 is formed with mounting pieces 20, 20, and the guide member 16 is attached to the vertical stile 2 and the lower stile by screwing the mounting pieces 20, 20 to the groove bottoms of the vertical stile 2 and the lower stile 3. It is attached to each corner of 3. Furthermore, the guide groove 19 of the guide member 16
is closed by a closing member (not shown). The closing member is attached by screws or the like.

A bendable and deformable slide member 18 (a chain in the embodiment) made of a spring wire or a chain is inserted into the guide groove 19 of the guide member 16 in a substantially L-shape along its longitudinal direction, and both ends of the slide member 18 are inserted into the guide groove 19 of the guide member 16. It is connected to operating rods 13 and 14 that protrude by a predetermined length from the tip of 16 with pins or the like.

In such a configuration, the slide member 18 can be bent and slid into the guide groove 19,
In particular, the corner portion of the guide groove 19 is
7 allows smooth sliding, and in conjunction with this, the operating rods 13 and 14 can simultaneously slide along the longitudinal direction of the vertical stile 2 and the lower stile 3.

In such a configuration, turn the handle 11 and slide the mounting pin 4 for the casement window and the mounting pin 5 for the folding window in the longitudinal direction of the vertical stile 2 and the lower stile 3, and remove the vertical frame 7 and the lower frame of the opening frame. By selectively engaging the pin receivers 9 and 10 of 8, the window can be opened and closed as a casement window or a folding window.

[Effect of idea]

As described above, the corner fitting of this invention is provided with a guide member at the corner part of the window stile, a substantially L-shaped guide groove is provided in this guide member along the corner part of the window stile, and a slide that can be bent and deformed is provided in this guide groove. The slide member is inserted through the curved race, and a curved race is arranged on the inside and outside of the guide groove corner portion, and a plurality of rollers are rotatably embedded in the opposing surface to serve as a rolling receiver. can be smoothly slid in the corner portion of the guide groove by the rolling receiver, especially its opposing rollers, and the transmission of force at the corner portion of the window stile of the operating rod can be carried out extremely smoothly and without waste.

Further, since a conventional chain can be used as the slide member, it can be manufactured relatively inexpensively and easily. Furthermore, since the race of the rolling receiver is provided separately, repairs can be made extremely easily by simply replacing the rolling receiver.
