Description

  The present invention relates to a window fitting that projects a shoji to the outside of a frame and opens it, such as a sliding window, a rotating window, and a case window.

  Conventionally, in a window fitting that opens the shoji to the outside of the frame, if the shoji is moved to the fully open position and the window is fully opened, there is a risk of an accident such as a child falling accidentally. , Equipped with a restriction device that can be switched between a restricted state and a non-restricted state that restricts the opening angle of the shoji. Normally, the shoji can be moved only to the half-open position, and the window can be opened only to the half-open state. In the case of limiting the angle and cleaning the shoji, etc., a window fitting has been proposed in which the shoji is moved to the fully open position so that the window can be fully opened.

  For example, as disclosed in Patent Document 1, by restricting the movement of the arm attached to the upper arm of the shoji with a lock plate provided on the upper frame of the frame, the opening angle of the shoji is restricted, and the lock plate is made special. A window fitting (rotating window) has been proposed in which the movement of the arm is not restricted by moving with a tool, and the shoji is moved to the fully open position so that the window can be fully opened.

Japanese Patent Laid-Open No. 11-93491

In the case of the conventional window fitting described above, since a general person cannot open the window fully, it is possible to prevent an accident such as a child accidentally falling from the window.
In addition, since a specific person such as a building manager or a person who cleans the window can open the window using a special tool, the window can be easily cleaned and inspected.
However, when closing a window in the fully open state, the specific person mentioned above greatly leans out of the window, extends his hand, touches the handle of the shoji in the fully open position, and points the shoji toward the closed position. Since it is necessary to move, there is a risk that a specific person may fall from the window during the operation, and a feeling of fear may be felt. This is the same when moving the shoji to the fully open position.

  The present invention does not allow a general person to open the window fully open, but a specific person can open the window fully open, and a specific person can safely close the shoji in the fully open position without fear. It is to make it a window fitting that allows the shoji to be opened safely and without fear.

The present invention is a window fitting provided with a restricting device that restricts the opening angle of the shoji while opening the shoji to the outside of the frame and opening it,
With the window closed, an airtight space is formed between the vertical frame of the frame and the vertical fence of the shoji,

It is a partially broken enlarged interior view of the part to which the restriction device is attached. It is a front view of the state which developed a restriction device. It is AA sectional drawing of FIG. It is explanatory drawing of the state which opened the shoji half. It is a perspective view of a switching jig. It is explanatory drawing of a lower arm and a switching jig. It is a top view of operation | movement description of the rotation with respect to the lower arm of a switching jig.

As shown in FIG. 1, the frame 1 and the shoji 2 are used as window fittings.
The frame 1 has a rectangular shape with an upper frame 10, a lower frame 11, one left and right vertical frame 12, and the other left and right vertical frame 13.
The shoji 2 has an upper gutter 20, a lower gutter 21, a left and right vertical gutter 22, and a right and left other gutter 23 connected in a square shape, and a panel 24 is mounted therein.
The shoji 2 is attached to the frame 1 so as to protrude and open to the outside of the frame 1.
For example, the sliding arm 3 is attached to each of the upper frame 10 and the upper frame 20 and the lower frame 11 and the lower frame 21, and the shoji 2 is attached to the outdoor side with the handle 25 attached to the left and right vertical rods 22. It is possible to move between an open position projecting to a closed position and a closed position in the frame 1 to form a vertical sliding window.
However, the present invention is not limited to this, and a rotating window, an open window or the like may be used.

A limiting device 4 for limiting the opening angle of the shoji is attached to the frame 1 and the shoji 2. For example, the restriction device 4 that restricts the shoji opening angle is attached to the left and right vertical frames 12 and the left and right vertical rods 22.
The restriction device 4 is switched between a restricted state in which the opening angle of the shoji is restricted by a switching jig described later and an unrestricted state in which the opening angle of the shoji is not restricted.

When the restriction device 4 is in the restricted state, as shown in FIG. 2 (a), the shoji 2 can only be moved to the half-open position, and the window can only be in the half-open state.
When the restriction device 4 is in the non-restricted state, as shown in FIG. 2B, the shoji 2 can be moved to the fully open position to open the window.
2A and 2B, the above-described sliding arm 3 is not shown.

The switching jig can be freely attached to and detached from the shoji 2, and the shoji 2 in the fully open position can be moved toward the closed position by using the switching jig.
For example, as indicated by a virtual line in FIG. 2B, a person holds the switching jig 5 by hand, protrudes from the frame 1 to the outdoor side, and the engaging portion 5a of the switching jig 5 is the shoji 2 in the fully open position. The switching jig 5 is connected to the shoji 2 by engaging with the engagement receiving portion 2a.
In this state, the switching jig 5 is moved from the frame 1 toward the indoor side, and the shoji 2 is moved toward the closed position.
When the shoji 2 has moved the handle 25 from the frame 1 to a position where it can be easily gripped without protruding outside, the switching jig 5 is removed from the shoji 2, and the shoji 2 is held by grasping the handle 25. Close and move to the closed position.

The shoji 2 can be moved to the fully open position using the switching jig 2.
For example, in a state where the shoji 2 is slightly opened with the handle 25, the engaging portion 5a of the switching jig 5 is engaged with the engaging receiving portion 2a of the shoji 2, and the switching jig 5 is connected to the shoji 2. The shoji 2 is pushed and moved to the fully open position so that the switching jig 5 protrudes to the outdoor side.

As described above, the shoji 2 cannot be moved to the fully open position unless the restricting device 4 is switched to the non-restricted state using the switching jig 5, so that a general person cannot open the window to the fully open position. Can be fully opened.
Further, since the shoji 2 in the fully open position can be moved toward the closed position using the switching jig 5 described above, a specific person can safely close the shoji 2 in the fully open position without fear.
Moreover, since the shoji 2 can be moved to the fully opened position using the switching jig 5 described above, a specific person can fully open the shoji 2 safely and without fear.
In addition, other members are unnecessary, and the cost can be reduced.

As shown in FIGS. 3 to 6, the restriction device 4 includes an arm 40 attached to one vertical rod 22 of the shoji 2 and a guide 41 attached to one vertical frame 12 of the frame 1.
One end of the arm 40 in the longitudinal direction is attached to the vertical shaft 22 so as to be swingable in the indoor outside direction by a support shaft 42. A slider 43 is attached to the other longitudinal end of the arm 40.
This arm 40 assumes a posture parallel to the vertical rod 22 by its own weight, that is, a vertical posture if no external force is applied.

  The guide 41 guides the slider 43 of the arm 40 so as to be slidable in the longitudinal direction of the vertical frame 12, and the slider 43 can be inserted and removed when the arm 40 is in a vertical posture. The switching state can be switched between a guide state and a guide state in which the slider 43 cannot be pulled out.

Therefore, if the guide 41 is in the non-guide state, the sliding element 43 is inserted into the guide 41 by setting the shoji 2 to the closed position, and if the shoji 2 is moved toward the open position, the sliding element. Since 43 comes out of the guide 41, the opening angle of the shoji 2 is not restricted, and the restricting device 4 is in an unrestricted state.
Further, when the sliding element 43 is inserted into the guide 41 with the shoji 2 in the closed position, the guide 41 is switched to the guiding state by the switching jig 5 described above, and when the shoji 2 is moved toward the open position, the sliding element 43 is moved. Slides along the guide 41, and the arm 40 rotates in a horizontal posture, so that the opening angle of the shoji 2 is limited by the arm 40. That is, the restriction device 4 is in a restricted state.

  As described above, the restricting device 4 can be switched between the restricted state and the non-restricted state when the shoji 2 is in the closed position. Therefore, in order to fully open the half-open window, the shoji 2 must be closed once. Therefore, safety is further improved.

An embodiment of the guide 41 will be described.
The guide 41 has a fixed guide 44 attached to the vertical frame 12 and a movable guide 45.
The fixed guide 44 has a first guide groove 46, and the first guide groove 46 extends in the longitudinal direction of the vertical frame 12 and opens at the lower end surface 44 a.
The movable guide 45 has a second guide groove 47, and the second guide groove 47 extends in the longitudinal direction of the vertical frame 12 and opens in the upper end surface 45a.
The movable guide 45 is movable between a first position and a second position. When the movable guide 45 is in the first position, its upper end surface 45a is the lower end surface of the fixed guide 44 as shown in FIG. 44a, the first guide groove 46 and the second guide groove 47 are continuously in the above-mentioned guide state in the vertical direction, and the sliding element 43 slides to the upper end of the first guide groove 46 by opening the shoji 2. Thus, the arm 40 is in a horizontal posture.

  When the movable guide 45 is in the second position, as shown in FIG. 4, the upper end surface 45a is separated from the lower end surface 44a of the fixed guide 44, and the slider is located between the upper end surface 45a and the lower end surface 44a. 43 can be inserted and removed freely, and the above-mentioned non-guide state is established. By opening the shoji 2, the slider 43 comes out of the guide 41, and by closing the shoji 2, the slider 43 is inserted into the guide 41.

The fixed guide 44 is formed in a substantially U-shape having a one-side attachment piece 44b, an intermediate guide piece 44c, and an other-side attachment piece 44d by bending a plate material, and the one-side attachment piece 44b and the other-side attachment piece 44d are The vertical frame 12 is fixedly attached to the inner surface 12a of the vertical frame 12 facing the vertical rod 22 with a fixing tool.
A first guide groove 46 is formed in the intermediate guide piece 44b.
The movable guide 45 has a long hole 45b, and a guide pin 45c slidably fitted in the long hole 45b is fixed to the other side mounting piece 44d, and the movable guide 45 is movable to the other side mounting piece 44d. It is attached to.
The movable guide 45 is formed with a receiving portion, for example, a recess 48.

As shown in FIG. 5, the vertical frame 12 has an inwardly facing piece 12b on the inner side of the inner side surface 12a facing in the indoor exterior direction, and a longitudinal seal member 12c is mounted on the inwardly facing piece 12b toward the outdoor side. is there.
The vertical rod 22 has an indoor vertical plate 22a, an outdoor vertical plate 22b, and a connecting plate 22c. The arm 40 is connected to the connecting plate 22c (that is, the outer surface facing the vertical frame 12) as follows. It is attached.
As shown in FIGS. 3 and 4, a bracket 49 is attached to the connecting plate 22c, and one end of the arm 40 is swingable in the interior and exterior direction and swings in the left-right direction on a support shaft 42 fixed to the bracket 49. The spring 49a is pressed against the bracket 49 and held in a vertical posture.
The bracket 49 has a pressing piece 49b which prevents the arm 40 from swinging to the outdoor side.

The vertical sealing material 22d attached to the outdoor vertical plate 22b is in contact with the inner side surface 12a of the vertical frame 12, and the indoor vertical plate 22a is in contact with the vertical sealing material 12c.
In this way, when the shoji 2 is in the closed state, an airtight and watertight space portion is formed between the inner surface 12a of the vertical frame 12 and the outer surface 22c of the vertical rod 22, and the space portion Since the limiting device 4 is attached, the watertightness of the window can be maintained.

As shown in FIG. 7, the switching jig 5 includes a bent piece 51 in which a longitudinal end portion of a long main body 50 is bent in a direction substantially perpendicular to the main body 50, and the bent piece 51 is continuous. And a distal end piece 52 that is substantially parallel to the distal end surface 52a of the distal end piece 52 and is bent in a direction substantially perpendicular to the distal end piece 52. The distal end bent piece 53 is the operation portion 5 b that fits into the concave portion 48 of the movable guide 45.
A protruding portion, for example, a rising piece 54 is provided on the upper end surface 52b of the tip piece 52, and this rising piece 54 is the engaging portion 5a. In this embodiment, the bent piece 51 and the tip piece 52 have the same width (the same vertical dimension), and the above-mentioned rising piece 54 is provided by notching the upper part.

Thus, as shown in FIG. 5, the folding piece 51 of the switching jig 5 is brought into contact with the sealing material 12 c of the vertical frame 12 and the tip piece 52 is pressed against the movable guide 45 with the shoji 2 opened. In this way, the tip bent piece 53 is fitted into the recess 48.
Thereby, since the main body 50 of the switching jig 5 goes to the indoor side from the window, it is easy to perform an operation of moving up and down with the main body 50 as described later.
By closing the shoji 2 in this state, the indoor vertical plate 22a of the vertical rod 22 comes into contact with the bent piece 51, and the longitudinal end portion of the switching jig 5 can be positioned in the above-described space portion.
Since the movable guide 45 can be moved to the first position and the second position by moving up and down with the main body 50, the restriction device 4 can be switched between the restricted state and the unrestricted state with the shoji 2 closed. it can.

As shown in FIG. 8, the lower saddle 21 of the shoji 2 has an indoor vertical plate 21a, an outdoor vertical plate 21b, and upper and lower horizontal plates 21c and 21d. A hole 21e is formed in the lower surface 21), and the above-described engagement receiving portion 2a is formed so that the rising piece 54 of the switching jig 5 is fitted into the hole 21e.
The hole 21e of the lower collar 21 can be formed at an arbitrary position in the longitudinal direction. However, if the hole 21e is formed at a position near the one end in the longitudinal direction and closer to the outdoor side when the shoji is opened, it is necessary to step up. When the hole 21e is formed near the other end in the longitudinal direction and closer to the indoor side when the shoji is opened, a large force is required to close the shoji, so the above-described hole 21e is formed in the middle portion of the lower collar 21 in the longitudinal direction. Is preferred.

Thus, the rising piece 54 of the switching jig 5 is brought into contact with the lower surface of the lower arm 21 of the shoji 2 in the fully open position and is slid in the longitudinal direction, so that the rising piece 54 is fitted into the hole 21e. The switching jig 5 can be connected to the lower arm 21 of the shoji 2 with a simple operation.
And since the hole 21e was formed in the lower surface of the lower collar 21, the hole 21e is hard to see and the appearance is good.

If the engaging part 5a of the switching jig 5 and the engaging receiving part 2a of the shoji 2 are formed in a shape that allows the switching jig 5 to rotate in the left-right direction with respect to the engaging part, Since the switching jig 5 can be rotated in the direction in which it can be easily pulled toward the indoor side by the opening angle of the shoji 2, the shoji 2 can be easily closed.
For example, as shown in FIG. 9, a circular hole 21e is formed in the lower horizontal plate 21d of the lower collar 21 to form the engagement receiving portion 2a, and the rising piece 54 (projection) of the switching jig 5 is used as the hole 21e. And a shape that can be rotated in the left-right direction around the hole 21e.
In this way, the switching jig 5 can be rotated in the left-right direction with respect to the lower rod 21 to the posture shown by the solid line, the posture shown by the one-dot chain line, and the posture shown by the two-dot chain line in FIG.
It is preferable that a fall prevention strap is attached to the switching jig 5 and the switching jig 5 is not accidentally dropped by hanging the strap on a wrist or the like.

The engagement receiving portion 2a of the aforementioned shoji 2 and the engagement portion 5a of the switching jig 5 are not limited to holes and rising pieces, and the engagement receiving portion 2a may be a projecting protrusion, a recess, a notch, etc. The joint portions 5a are engaged with them so as not to move in the longitudinal direction.
Further, the engagement receiving portion 2a may be fixed to the shoji 2, for example, the lower arm 21, as a separate body from the shoji 2, and the engaging portion 5a may be fixed to the switching jig 5 as a separate body.

The switching jig 5 may be short when switching the control device 4 so that the length is adjustable, and may be long when the shoji in the fully open position is moved toward the closed position.
For example, the main body 50 is foldable and slidable.
In this way, even in the case of a window having a large opening width, the shoji 2 in the fully open position can be safely moved toward the closed position, and the restriction device 4 can be easily switched.
