Description

[Detailed description of the invention] Industrial application field This invention is a double-sliding window in which multiple shoji doors are built in a window frame in a sliding manner in the same direction, or a single shoji door can be moved freely in the in-plane direction. This relates to sliding windows such as built-in single sliding windows.

Prior Art As shown in West German Patent Application No. 2926113, locking protrusions are fixed to the top and bottom of the vertical frame side of a window frame,
A locking receiving seat is provided on the door edge stile of the shoji door to be moved up and down by a handle and engaged with the locking protrusion, and a door wheel frame equipped with wheels is provided on the lower stile so as to be movable vertically and horizontally. The door roller frame is connected to the locking seat via a link mechanism, and a roller facing the arcuate groove of the block fixed to the lower stile is attached to the door roller frame, and when the locking seat is moved up and down, the door roller frame is moved. moves left and right, and the arc groove and roller move the door frame up and down, so that when the shoji door is closed, the shoji door moves downward relative to the window frame, and when the shoji door is opened and closed, the shoji door moves vertically. Sliding windows in which the door moves upward relative to the window frame are known.

Problems to be Solved by the Invention In such a sliding window, the vertical movement stroke relative to the lower stile of the door frame is determined by the shape of the circular arc groove, the roller, and the amount of left-right movement of the door frame. The amount of horizontal movement of the shoji door is determined by the vertical movement stroke of the locking seat, and when the locking seat does not move up and down, the door frame does not move left and right, so the shoji door cannot be moved up and down regardless of handle operation. Installation cannot be adjusted.

Means and action for solving the problem A driven roller of the door frame equipped with wheels is installed so that it can be moved up and down by a moving mechanism, and a cam that contacts this driven roller is fixed to the lower stile to move the door frame from side to side. The shoji door can be moved up and down with respect to the window frame by moving the driven roller up and down without moving the window frame.

Example Fig. 7 is an overall front view of a single sliding window, and the window frame 1
has a rectangular frame shape with an upper frame 2, a lower frame 3, and a vertical frame 4, and a large shoji door 5 is built in the window frame 1 so as to be movable in the in-plane direction. The door 5 has an upper stile 6, a lower stile 7, a door end stile 8, and a door end stile 9 framed in a rectangular shape, and a glass 10 is mounted inside the door.

A handle 11 is rotatably supported on the door frame 8, and bases of a pair of upper and lower bars 12 are connected to a rotating portion 11a of the handle 11 via a pinion and a rack or a link mechanism to rotate the handle 11. A pair of upper and lower locking rods 13 are respectively fixed to the tips of the upper and lower pairs of bars 12, and the locking rods 1
A pair of upper and lower receiving seats 14 are fixed to the upper and lower sides of the vertical frame 4, with which the tip ends of the vertical frame 4 engage.

A door frame 16 equipped with wheels 15 is provided on the left and right sides of the lower stile 7 so as to be movable left and right.
7 is fixed, and a driven roller 18 facing this cam 17 is attached to the door roller frame 16 so as to be able to move up and down by a moving mechanism 19. The left and right door roller frames 16 are connected by a connecting rod 20, and one The door wheel frame 16 is connected to the lower locking rod 13 via a link mechanism 21, and each wheel 15 is rotatable along the rail 3a of the lower frame 3.

As shown in FIG.
4a and the horizontal piece 14b form an L-shape, and the horizontal piece 14b has a locking hole 14c formed therein, the vertical piece 14a is fixed to the vertical frame 4, and the horizontal piece 14b
is located slightly above the rail 3a, and the locking rod 13
When the tip of the locking rod 13 engages with the locking hole 14c, the shoji door 5 is pulled toward the vertical frame 4, and the locking rod 13 is integrally formed with a protrusion 13a at its tip.

The link mechanism 21 includes an intermediate lever 24 and a connecting lever 25, which are pivotally connected with a pin 23 to a guide plate 22 fixed to the door frame 8 so as to be movable up and down, and one end of the intermediate lever 24 is connected to a locking rod. Pin 26 to 13
The other end is pivotally connected to a connecting lever 25 with a pin 27, and the connecting lever 25 is pivotally connected to the door roller frame 16 with a pin 28.
When the locking rod 13 moves up and down, the door wheel frame 16 moves left and right, and when the locking rod 13 moves upward as shown in FIG. 2, the other end of the intermediate lever 24 interferes with the projection 13a, causing the door wheel to move. The amount of movement of the frame 16 is regulated.

As shown in FIG. 3, the lower stile 7 has vertical walls 7 on both sides.
A, 7a and the connecting horizontal wall 7b form a downward opening 7', and a pair of protrusions 7c are formed in the downward opening 7' of both vertical walls 7a, 7a. The door frame 16 has vertical plates 16a, 16a on both sides.
are connected at predetermined intervals and housed in the downward opening 7' so as to be movable vertically and horizontally, and a protrusion 16b that engages with the protrusion 7c is formed on both vertical plates 16a, 16a. , the door frame 16 is opened at the downward opening 7'
Insert the protrusion 16b into the protrusion 7 from the longitudinal direction.
c, the door roller frame 16 is moved into the downward opening 7'.
The shoji door can be held more securely from falling, and there is no need to hold the door frame 16 by hand when erecting the shoji door, so the shoji door can be easily erected.

The vertical plates 16a and 16a are shown in FIGS. 1 and 4.
As shown in the figure, a long hole 30 in the vertical direction is formed,
A support piece 3 fitted into this elongated hole 30 so as to be slidable up and down
A support shaft 32 is horizontally supported between the support shafts 1 and 1.
2, a driven roller 18 is attached via a one-way clutch 33, and one end of a pair of arms 34 is supported, and the other end of the pair of arms 34 is supported by a shaft 36 projecting from both ends of a sliding piece 35. The protruding shafts 36 at both ends thereof face slidably into elongated holes 37 in the left and right direction formed in the vertical plates 16a on both sides, and the screw rods 39 screwed into the screw holes 38 of the sliding pieces 35. The intermediate flange 39a is the vertical plate 16a on both sides,
It is held so as not to move in the left-right direction by a pair of locking pieces 40 fixed between the threaded rods 39, and a disk 41 is provided at the end of the threaded rod 39. A large number of holes 42 are formed at intervals, and an opening window 43 facing the holes 42 is formed in the vertical wall 7a on one side of the lower stile 7, and a rod or the like can be inserted into the hole 42 through this opening window 43. Together, disc 4
1, the screw rod 39 can be rotated. When the screw rod 39 is rotated, the sliding piece 35 slides in the left-right direction along the elongated hole 37, and the pair of arms 34 swings up and down to rotate the support piece 31. moves up and down along the elongated hole 30, so the driven roller 18 moves up and down with respect to the door wheel frame 16, forming a moving mechanism 19.

On the other hand, the cam 17 is fixed to the connecting horizontal wall 7b of the lower stile 7, and has a straight slope surface 17a inclined in the vertical direction.
The linear blade surface 17a has a driven roller 18
As the door roller frame 16 moves, the door roller frame 16 moves up and down.

A block 50 is fixed to the end of the door roller frame 16, and the connecting rod 20 is fitted and fixed in the hollow part 51 of the block 50, thereby connecting the left and right door roller frames 16.

However, when the shoji door 5 is closed, the handle 1
1 is rotated 180 degrees, the bar 12 moves up and down, the tip of the locking rod 13 engages with the engagement hole 14c of the catch seat 14, and the shoji door 5 is pulled toward the vertical frame 4 and locked.

At the same time, the intermediate lever 24 swings counterclockwise about the pin 23 due to the downward movement of the locking rod 13 in FIG.
The door roller frame 16 is moved to the right via .

As a result, the driven roller 18 moves to the right along the linear slope surface 17a of the cam 17, and the driven roller 18 moves upward with respect to the cam 17, so that the door roller frame 16 is moved to the lower stile 7. Since the shoji door 5 moves upward relative to the window frame 1 and the shoji door 5 moves downward relative to the window frame 1, the lower frame 3 of the window frame 1 and the lower stile 7 of the shoji door 5
It is possible to maintain airtightness between the

At this time, the driven roller 18 cannot rotate relative to the support shaft 32 due to the action of the one-way clutch 33, so it slides along the linearly sloped surface 17a of the cam 17, and the driven roller 18 is made of a highly elastic material. Therefore, the shoji door 5 slowly descends to suppress drop acceleration, and the movement of the door wheel frame 16 causes the handle 1 to move through the link mechanism 21, locking rod 13, and bar 12.
1 is not rotated upward suddenly, so it is safe.

This state is the state shown in FIGS. 1 and 7.

When the handle 11 is rotated downward from the above-mentioned state, the bar 12 moves up and down and the locking rod 13 moves into the catch seat 14.
The shoji door 5 is released from the locking hole 14c, and the shoji door 5 is pulled and locked.

At the same time, the intermediate lever 24 in FIG.
swings clockwise around the pin 23 and moves the door roller frame 16 to the left via the connecting lever 25, so that the driven roller 18 moves against the linear slope surface 1 of the cam 17.
7a, and the door frame 16 moves downward along the lower stile 7a.
Since the shoji door 5 moves downward relative to the window frame 1, a large gap is formed between the lower frame 3 and the lower stile 7, and the shoji door 5 is moved by the wheels 15.
It is possible to run smoothly along the rail 3a of the lower frame 3 via the rail 3a of the lower frame 3.

At this time, the driven roller 18 can rotate with respect to the support shaft 32 by the action of the one-way clutch 33, so it moves while rotating along the linear slope surface 17a of the cam 17, and can be moved with a small force.
1. Operation force can be reduced.

Furthermore, as described above, by rotating the disk 41, the driven roller 18 can be moved up and down with respect to the door frame 16, so when the shoji door 5 is installed in the window frame 1, the door frame 16 can be moved to the lower stile 7. On the other hand, the shoji door 5 can be moved up and down with respect to the window frame 1 to adjust the installation.

It goes without saying that it can also be applied to double-sliding windows with a pair of shoji doors.

Effects of the invention: Since the driven roller 18 can be moved up and down with respect to the door frame 16 by the moving mechanism 19, the installation can be adjusted by moving the shoji door up and down with respect to the window frame 1, regardless of the handle 11. .

By moving the locking rod 13 up and down with the handle 11, the link mechanism 21 moves the door frame 16 left and right, and the driven roller 18 and cam 17 move the shoji door 5 downward relative to the window frame 1. It can be moved and moved upwards.
