JPS5916632B2 - Pulling device for single sliding soundproof shoji - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for reliably pulling shoji with a simple mechanism and high soundproofing performance.

As is well known, in order to improve the sound insulation performance of current soundproof shoji shoji, a pulling device built into the vertical stile of the shoji, commonly known as the Gremont pulling handle method, is operated by rotating the handle. By making the left and right sides adhere closely to the frame,
That is, the upper and lower ends of the shoji utilize the reaction of cams whose tips tip in the direction of indoor and outdoor directions, and the upper and lower cams up to the handle are connected with rods, and the upper and lower rods are connected downward and upward. It was equipped with a displacement mechanism such as a rack, pinion, or eccentric cam disc that was linked to the rotation of the handle in order to pull it.

The parts that make up the mechanism, such as stationery, must maintain considerable strength and corrosion resistance, and the dimensions of the mechanism that indirectly seals must also be accurate. It was not uncommon for internal failures to occur, and repairs that occurred internally required a lot of effort.

The present invention does not adopt an indirect method using a handle as a pulling method, and when the shoji moves along guide rails attached to the upper and lower frames, when it reaches the pulling closed position, the pulling roller and the pulling roller The present invention provides a method and device for automatically and reliably making an airtight window by moving the shoji in the drawing direction (indoors) by direct interlocking of the access blocks.

Embodiments will be described below with reference to the drawings.

FIG. 1 is a front view of the soundproof single sliding shoji screen seen from the indoor side.

FIG. 2 is a plan view taken from A to A in FIG. 1, with A indicating the indoor side and B indicating the outdoor side.

Note that this is a side view of the guide car and roller car.

FIG. 3A is a side view of FIG. 1 cut in a ro-ro view, showing the position of the shoji when it is closed, with A showing the indoor side and B showing the outdoor side.

The opening in Figure 3 is a side view of the door roller.

In the drawing, 1 is the upper frame t, 2 is the lower frame, 3 in FIG. 2 is the vertical frame, and 4 is the vertical frame of the shoji.

In addition, the upper and lower frames are used as the upper and lower frames of the shoji shoji, with approximately i on the indoor side.

5 is the upper stile of the shoji, 6 is the lower stile, and 7 is the vertical stile.

8 is glass and 9 is a door wheel.

The above are the frame constituent members of the shoji and the frame materials of the shoji.

As shown in the cross section of the upper frame 1 in Figure 3, the upper frame is equipped with a guide rail R1, which is a vertical wall hanging downward from the ceiling wall, and a guide rail R2, which is a vertical wall with a pocket, which are parallel to each other. The interval between the two guide rails R1 and R2 is approximately equal to the outer diameter of the guide wheel W, which will be described later (actually, there is a slight clearance).

Similarly, on the lower frame forming a step-like shape, a guide rail R1, which is a vertical wall, rises from the outside at a position opposite to guide rails R1 and R2 of the upper frame, and a guide rail is a vertical wall having a roller. R2 is provided in a hanging form, and the distance between them is naturally equal to the outer diameter of the guide wheel W, as in the case of the upper frame.

The second horizontal plane from the outside will be the running path for the single sliding shoji.

Next, guide rail R for both the upper frame and lower frame as shown in Figure 3.
1, that is, a small pulling block 11 made of hard synthetic resin or the like is attached and fixed to the inside of the guide rail on the outdoor side.

Further explaining with reference to FIG. 2, the drawing block on the right side in the figure is the small drawing block 11, and its shape (thickness) is such that it maintains a constant thickness from the left end and forms an inclined surface from the middle. The thickness approaches O at the right end.

In reality, there is no difference between 2 and 3 m/m.

In other words, the right half of the block has the shape of an isosceles triangle cut in half.

The planar shape of this pulling block small 11 is of course an upper frame,
Both the lower frames are the same (heights can be different), and the position where they are installed and fixed is the exit at the position where the single sliding shoji is fully opened and the sliding shoji overlaps with the shoji. If you look at it, it is on the left in a diagram of a shoji stile.

Next, to explain the pulling block dog 12, as shown in FIG. 2, compared to the pulling block small, the constant thickness part is 2.
The thickness is slightly less than that of the small block, and the inclined surface is also longer than that of the small block.
There is no need for the right end to be 0.

That is, the end may be formed with a thickness equal to the thickness of the large block than the small block (difference in thickness).

As for the mounting position, both the upper frame and the lower frame are fixedly attached to the right side of the inner end of the vertical frame 3 as shown in the figure.

In FIG. 3, only small blocks are shown, and large blocks are not shown.

Next, the guide block 13 will be explained.

The guide block is also made of a material such as hard synthetic resin, similar to the pulling block, and the guide rail R of the upper frame and lower frame
It is attached and fixed to the indoor side of the pocket 14 facing the pulling block, and when its shape is viewed from above in FIG. The right side of the pocket in the figure faces the inclined surface of the drawing block and is maintained at an equal distance (parallel) from each other.

It should be noted that a part of the guide rail R2 is cut out and fitted into the guide rail R2.

To explain the details further, 15 is made of elastic material such as synthetic rubber, which is inserted into the groove of each frame around the four circumferences including the upper frame, lower frame, vertical frame, and vertical frame of the shoji. It is formed in.

16 is removably attached to the outdoor side of the lower frame, that is, the upper surface of the bottom tier, and is described as a part of the lower frame, but it is only necessary to insert and install it when erecting the shoji or removing the shoji. In order to make it removable from the lower frame, it is assembled and fixed together with screws as a separate section, but there is no other functional significance.

Next, to explain the structure of the main parts of the shoji, Figure 3 shows the position of the shoji when it is in the closed and sealed state when the single-drawing shoji is drawn. A guide wheel W and a pulling roller 1 (each of which is shown to be freely rotatable and mounted in a conventional manner to a vertically mounted shaft 17).

As described above, the outer diameter of the guide wheel W is equal to the distance between the two guide rails R1 and R2, and the outer diameter of the roller 19 is slightly smaller than the outer diameter of the guide wheel W.

The mounting position when viewed from the front of the shoji is to the left of the right stile of the shoji and as close to the stile as possible as shown in the figure.

Similarly, a guide wheel W and a pulling roller wheel 20 are attached to shafts 17 that are fixed perpendicularly to the upper and lower surfaces of the upper and lower stile, respectively, at a position as close as possible to the right side of the left vertical stile of the shoji. Each is mounted rotatably.

However, the outer diameter of the pulling roller wheel 20 is small, and when expressed as a radius, it is equal to the radius of the guide wheel W minus the thickness of the small pulling block.

In other words, the radius of the guide wheel W is the sum of the thickness of the small pulling block and the radius of the single pulling roller.

The sizes of the guide wheels and roller wheels indicated by dotted lines in FIGS. 2 and 3 show the state in which the shoji has not yet been drawn.

Note that one door wheel 9 is attached to the lower surface of the lower stile of the shoji in the usual manner, one each on the left and right, and the door wheel 9 is preferably located inside the center of the guide wheel W attached to the lower surface of the lower stile.

It goes without saying that the door roller simply supports the load of the shoji, and does not run along the rail as a combination of a rail and door roller like a general door roller.

If a folding door roller, which has been developed as a prior art, is used, the sliding of the shoji will become even smoother.

In Fig. 3, lines C1 to C1 and lines 02 to 02 indicate the position of the shaft 17 when the shoji is closed, and the latter indicates the position of the shaft 17 when the shoji is closed (
The position of the shaft 17 is shown (when opened).

Next, to explain the operation, first, let's assume that the single sliding shoji starts from the fully open position, the load of the shoji is supported by the door roller, and the four guide wheels of the upper and lower stile are moved to the guide rail R of the upper frame.
1 and R2, and the shoji can run straight while being guided by the guide rails R1 and R2 of the lower frame.

Next, when driving further and approaching the closing time, the upper and lower pulling blocks are thicker as shown in Figure 2, so the pulling rollers move along the slope toward the indoor side. As the shoji is being changed, the shoji is pulled toward the indoor side, and at the same time, the pulling roller block that follows is thicker (the advancing roller block passed straight through), so it hits the inclined surface of the pulling block small and moves in the direction of travel. By changing the shoji, the shoji is pulled towards the indoor side, and the guide cars for the father and his wife follow the pull, and the guide cars run into the pocket, allowing the shoji to be smoothly pulled towards the indoor side in the completely closed position. Combined with the function of the gaskets provided on the top, bottom and vertical frames, it maintains a completely airtight state.

When opening from the closed state, the fully open state is reached by the reverse operation to the above.

As explained above, unlike the conventional mechanism, the parts for pulling are made simple in terms of material and shape, making them suitable for mass production, and making the single-pull sliding shoji reliable and trouble-free, which is extremely effective in practice.
