Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a lower guide device for an indoor shoji of a vertical window used in building construction or housing.

[Prior art]

Conventional lift-down windows are generally ones with the upper shoji placed on the outside of the room and the lower shoji placed on the inside of the room, such as the one seen in Japanese Utility Model Publication No. 59-13574, and each has a rigid frame guide. It is designed to be able to slide up and down within the groove. However, if one shoji is placed on the outdoor side and the other on the indoor side, even when the window is closed, there will be a level difference between the shoji on the indoor side and the shoji on the outdoor side, making it difficult to maintain sufficient watertightness. ,
There is a problem that airtightness cannot be achieved.

Further, Japanese Utility Model Publication No. 56-109386 discloses a single-side up/down window in which the lower part is a fitted window, the upper shoji slides in the vertical direction, and when the door is locked, it can be flush with the fitted window part. However, the shoji had to be raised and lowered without being attached to the window frame, making the appearance unsightly.
The operation is also complicated. Also, it cannot be applied to a raised/lowered window where two shoji screens go up and down.

[Purpose of invention]

The raised/lowered window in this invention was developed in view of the problems in the future, and this invention consists of two shoji screens suspended from the upper frame or the frame by a balancer, each mounted on the frame of the window. To provide a lower guide device for an indoor-side shoji of a lift-down window, which is movable up and down along a guide groove formed by the shoji and is capable of making the shoji on the indoor side flush with or almost flush with the shoji on the outside when locked. With the goal. Also,
This improves the watertightness and airtightness of the windows.

[Structure of the idea]

The hinged window used in this invention has an indoor shoji and an outdoor shoji built into a window frame consisting of an upper frame, a lower frame, and left and right frames. It moves up and down along the indoor guide groove and the outdoor guide groove provided in the frame.

The indoor shoji has a first sliding member and a second sliding member that protrude left and right, and the indoor shoji is raised and lowered by sliding in the indoor guide groove.

In addition, the first part of these indoor shoji screens is placed on the frame of the window frame.
A first horizontal guide groove and a second horizontal guide groove are formed to guide the sliding member and the second sliding member and horizontally move them to the outdoor side, and move the indoor shoji to the outdoor side and move the indoor shoji to the indoor side. It is designed to be flush or nearly flush with the shoji.

The indoor shoji and the outdoor shoji are suspended from the window frame or the frame by elastic balancers such as springs.

The balancer is designed to balance the load of the shoji, and allows the shoji to be held at a desired height when being raised or lowered.

The lower end of the balancer that suspends and supports the indoor shoji is connected to the second sliding member via a bending guide piece. This folding guide piece has both ends rotatably connected by pins or shafts, etc., and when the indoor shoji moves to the outdoor side with the balancer attached, the second sliding member moves to the second horizontal guide. This allows for smooth movement within the groove. In addition, by providing a protrusion that serves as a fulcrum for rotation on the outdoor side of the bending guide piece, the bending guide piece can be easily rotated and can be prevented from getting caught.
