Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fulcrum holding device for a vertically foldable window using a balancer, and is used for building construction, housing, etc.

[Prior art]

Conventionally, there is a structure as seen in Japanese Utility Model Application Publication No. 59-13574, for example, as a lift-down window that can be folded inwards. In other words, regarding the indoor shoji,
A guide pin that can be moved in and out of the guide groove is provided, and by recessing this guide pin, it is possible to tilt toward the indoor side around other guide pins. By making it possible to fold down such a vertical window, the advantages include not only ventilation but also the ability to easily clean the outside surface of the shoji room.

Furthermore, Japanese Utility Model Application Publication No. 59-13575 discloses a mechanism for raising and lowering windows that can be stopped at any position and folded inward using a balancer for a window in which only the lower shoji on the indoor side can be raised and lowered. .

However, in the case of such a structure, if the shoji and the balancer are tilted inward, the balance between the shoji and the balancer cannot be maintained, and there is a risk that the pivot position of the tilted inward position may be lifted.

[Purpose of the invention] The device of this invention was devised in view of the above-mentioned problems in the conventional technology. The purpose of this project is to provide a safe and multifunctional window that can be raised and lowered so that the fulcrum does not rise due to the tension of the balancer even when the window is folded inward.

[Structure of the idea]

The vertically foldable window 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 vertical frames, and the indoor shoji and outdoor shoji are It moves up and down along the indoor guide groove and the outdoor guide groove provided in the vertical frame of the frame.

These indoor-side shoji and outdoor-side shoji are suspended from the window frame or vertical frame by elastic balancers such as springs. The balancer is designed to balance the load of the shoji.
The shoji can be held at any height when raising or lowering it.

Moreover, at least one, preferably both, of the indoor-side shoji and the outdoor-side shoji can be folded inwards to the left and right. Considering an indoor shoji, a first sliding member that protrudes left and right and can be retracted and a second sliding member that serves as a fulcrum of rotation is formed, and it slides up and down in the guide groove of the vertical frame, and The first sliding member can be retracted at a height of , and the second sliding member can be tilted inward using the position of the second sliding member as a fulcrum. The same applies to the outdoor shoji, and both shoji can be configured so that they can be folded inward at any height.

The second sliding member, which serves as a fulcrum for rotation, consists of a sliding member main body and a widened piece whose upper portion is fixed to one side of the sliding member main body with a screw or the like. Moreover, a support shaft that rotates together with the shoji is fitted into this second sliding member, and a cam surface formed on this support shaft comes into contact with the lower part of the widening piece when the shoji is raised or lowered. When the shoji is folded inwards, it rotates together with the shoji to push out the widening pieces in the direction of the shoji. As a result, the widening piece is pressed against the wall portion of the guide groove, preventing the second sliding member from sliding, and when it falls inward, the balanced state is lost and the fulcrum of rotation is lifted by the balancer. is prevented.

〔Example〕

Next, the illustrated embodiment will be described.

Figures 1 to 5 show the functions of the vertical window in this embodiment. In the figures, 1 is the window frame, 1a is the upper frame, 1b is the lower frame, 1c is the left and right vertical frames, and 2 is the indoor side. Shoji, 2a, 2b, 2c, 2d are respectively the upper stile, lower stile, vertical stile, panel (glass etc.) of indoor shoji 2, 3 is outdoor shoji, 3a, 3b, 3c, 3d
are the upper stile, lower stile, vertical stile, and panel of the outdoor shoji 3, respectively.

Figure 1 shows the window closed. FIGS. 2 and 3 show the raised and lowered states. FIG. 2 shows a state in which only the indoor shoji 2 is raised and lowered, and FIG. 3 shows a state in which the outdoor shoji 3 is also raised and lowered.

Figures 4 and 5 show the state in which only the indoor shoji 2 is tilted inward;
FIG. 5 shows a case where the outdoor shoji 3 is also tilted inward.

FIGS. 6 and 7 show the inside of the upper frames 2a and 3a of the indoor shoji 2 and the outdoor shoji 3 when they are raised and lowered and when they are folded inward, respectively.

At the upper edge of the indoor shoji 2, a pair of arms 40 having an indoor first sliding member 31 at their tips are connected to a handle 3.
An upper Gremont device 37 that can be pulled freely by the operation of 8 is attached, and the guide case 39
An arm 40 slides within the interior, and a first indoor sliding member 31 that protrudes from side to side can move in and out. This indoor first sliding member 31 is the first indoor sliding member 31 of the vertical frame 1c.
It slides up and down in the guide groove 11.

At this time, the amount of pulling of the mounting base of the arm 40 is limited by the central trigger 43 to prevent the indoor first sliding member 31 from coming off the indoor guide groove 11. The amount of pulling by the trigger 43 is limited by pushing the knob 43a toward the outdoor side, thereby pulling the trigger 43 out of engagement with the end of the retraction arm 40.

For the outdoor shoji 3, there is a latch lock 56 on the upper edge.
By operating the knob 56a, the outdoor first sliding member 51, which can move in and out of the outdoor first guide groove 13 of the vertical frame 1c, protrudes left and right, and the outdoor first guide groove 13
It is designed to slide up and down along the

When folding inward, trigger 4 for indoor shoji 2
When the handle 38 of the upper Gremont device 37 is turned horizontally to the left while the knob 43a of No. 3 is pushed toward the outdoor side, the indoor first sliding member 31 is pulled out from the indoor first guide groove 11, and in this state it is moved under the shoji. It can be tilted inward using the position of the indoor second sliding member (not shown) on the side as a fulcrum.

Regarding the outdoor shoji 3, the knob 56a of the latch lock 56 is operated to pull out the outdoor first sliding member 51 from the outdoor first guide groove 13, and the second outdoor sliding member 52 is positioned as described later. It can be tilted inward using as a fulcrum.

Figures 8 and 9 show the lower stile 3b of the outdoor shoji 3.
This shows what it looks like inside.

A second outdoor sliding member 52 protrudes from the left and right sides of the lower end and slides vertically within the second outdoor guide groove 14 shown in FIG. 6. This outdoor second sliding member 52 is connected to the support shaft 5
It is attached to the outdoor shoji 3 via 5,
The outdoor shoji 3 is rotatable around this support shaft 55. In addition, one end is attached to the upper frame 1a or the vertical frame 1c.
An outdoor balancer 53 made of a spring or the like fixed to is connected to the second outdoor sliding member 52 via a connecting fitting 54 . This outdoor balancer 53 is designed to balance the load of the outdoor shoji 3, so that the outdoor shoji 3 can be held at an arbitrary height.
