DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door pocket for storing a shutter, and more particularly to a structure for reducing the pulling force of the shutter from the door pocket.

[0002]

2. Description of the Related Art A conventional door pocket for storing a shutter has a lower frame formed in a horizontal plate shape. When pulling out and sliding, put your hand through the door opening provided at the middle height of the wife plate, and insert your finger into the grooved finger hook provided in the shutter to pull it out.

[0003]

When the shutter is to be pulled out from the door pocket as described above, the fingertip 1 is hung on the groove-shaped finger hook 2a of the shutter 2 as shown in the schematic cross-sectional view of FIG. Then, the outside surface of the door 2b side of the shutter 2 is brought into contact with the door 4 of the door pocket 3 and the abutment part p is used as a fulcrum.
The c-side must be moved in a lever-like manner as indicated by an arrow R so that the direction of the shutter 5 coincides with the direction of the rail 5 of the shutter frame, and then the door must be pulled out. In this case, since the distance from the contact portion p to the door bottom 2c is much longer than the distance from the finger hook portion 2a to the contact portion p, the innermost shutter 2 is pulled out when the number of stored shutters 2 is large. At times, it is necessary to swing the shutter largely as shown by the arrow R, so that there is a problem that it is difficult to smoothly pull out the shutter. As means for solving such problems, a spring is attached to the inner surface of the end plate of the door pocket and the shutter is urged by the force of the spring,
Although a door car is made to have a special structure, there is a problem that the structure is complicated and the price is increased.

The present invention has been made in view of the above-mentioned problems of the prior art,
It is an object of the present invention to provide a door pocket having a simple structure and capable of reducing the pulling force of the shutter without increasing the price.

[0005]

The door pocket of the present invention comprises an upper frame,
A lower frame, a side plate, a wife plate, and a mirror plate are configured to house a shutter inside, and the lower frame is provided with a horizontal portion on the indoor side,
The inclined portion where the outdoor side of the lower frame is raised on the outdoor side is the horizontal portion.
Between the horizontal part and the inclined part.
Is an R surface .

[0006]

In the present invention, since the lower frame is provided with a slope such that the indoor side is downward, when the shutter is pulled out, the door end side of the shutter easily slides down to the indoor side, which is necessary for pulling out the shutter. Power is reduced. Also, the horizontal part and the inclined part
Are formed integrally, and between the two is formed on the R surface.
Allows the shutter to slide smoothly between the slope and the horizontal
You.

FIG. 1 shows an embodiment of a door pocket according to the present invention.
It is EE sectional drawing of FIG. 5 mentioned later. FIG. 2 is a sectional view of FIG.
FIG. 3 is an enlarged cross-sectional view of the lower frame, and FIG.
FIG. 5 is a perspective view showing the door pocket and the entire sash frame. 4 and 5, 2 is a rain door, 3 is a door pocket, 6 is a sash frame, and the sash frame 6 is composed of an upper frame 7 and a lower frame 8 on which a shoji or a screen door (both not shown) are mounted so as to be freely movable. And these are connected to the vertical frame 9. The rail 5 of the shutter 2 is formed on the outdoor side of the upper frame 7 and the lower frame 8. The door pocket 3 includes an upper frame 10, a lower frame 11, a side plate 12, an end plate 13, and an end plate 14.
Are connected by a fixing tool 21 such as a screw.

The upper frame 10, the lower frame 11, the side plate 12, the end plate 13
Is made of an aluminum alloy shaped material, and the end plate 14 is composed of a flat plate 15 and a corrugated plate 16, and the end plate 14 is made of an aluminum alloy mounted on the upper frame 10, the lower frame 11, the side plate 12, and the end plate 13. Mounting plate 17-2 made of shaped material
0 is attached.

As shown in FIGS. 1 and 3, a lower frame 11 has
From the middle part in the indoor / outdoor direction to the outside of the room, an inclined part 11a with a high outside and a low inside is provided, and a horizontal part 11b from the middle to the inside is formed. Also, the inclined portion 11a
An R surface 11c is provided between the horizontal section 11b and the horizontal section 11b, so that the shutter 2 can smoothly slide between the inclined section 11a and the horizontal section 11b. Two door stop stoppers 22 are fixed to the side plate 12 with a space above and below by a fixing tool (not shown) such as a screw. These stoppers 2
2 has an inclined surface 22a that guides the door end 2c to the outside when the shutter 2 is stored.

As described above, by providing the lower frame 11 with the inclined portion 11a, when the shutter 2 is pulled out, the shutter 2 receives the force of sliding down the indoor at the inclined portion 11a. The movement shown by the arrow R of the door bottom 2c is easily performed, and the shutter 2 can be easily pulled out.

Here, the door pocket has a width of about 1 m and a height of about 1.
For the one that accommodates four 8m shutters 2, the slope 1
FIG. 6 shows the results obtained by measuring the door-in force and door-out force with a spring-type push-pull gauge when the inclination angle θ of 1a is variously changed. FIG. 6 shows the maximum force required to finish closing the most indoor-side shutter 2 as a relative value with the value when there is no inclination being 100, and the door-opening force is the innermost door. The maximum force at the time of drawing out is shown as a relative value when the value when there is no inclination is set to 100. As can be seen from FIG. 6, when the angle of the inclined portion 11a of the lower frame 11 becomes 2 degrees or less, the door opening force rapidly decreases. The door-opening force is reduced as the inclination angle of the lower frame 11 increases, while the door-opening force increases as the inclination angle increases. However, when the shutter is accommodated, a relatively large force can be directly applied to the shutter by pushing the shutter 2 with the palm, and there is no need to apply a lever-like force as described in FIG. Tojiri 2
Since the c side is guided by the inclined surface 22a of the stopper 22, the direction is automatically changed and the shutter 2 can be inserted,
Increasing the door power is not a major problem. However, when the inclination angle of the inclined portion 11a of the lower frame 11 exceeds 8 degrees, the door opening force is more than double as compared with the case where the entire lower frame is a flat surface. The angle is preferably set to degrees to 8 degrees, and more preferably the inclination angle is set to a range from 4 degrees to 5 degrees.

Further, in the present invention, the entire lower frame 11 may be inclined. However, as shown in the embodiment, if the outside of the room is made the inclined portion 11a rather than the intermediate portion, a large door-out force is required. This is preferable in that the door-opening force of the rain door at the back of the door pocket is reduced, and the door-opening force is made uniform as a whole.

In practicing the present invention, the specific shape and structure of the door pocket, its lower frame or the inclined portion can be variously changed.

[0014]

According to the first aspect of the present invention, since the inclined portion is provided in the lower frame of the door pocket, when the rain door is pulled out from the door pocket, the door bottom can smoothly slide down to the indoor side, and the door-out force can be reduced. The shutter can be easily pulled out. Further, the present invention can be carried out simply by changing the shape of the lower frame made of a shaped material, and therefore can be carried out at low cost without complicating the structure or increasing the number of parts. The lower frame has a horizontal portion on the indoor side, and has a horizontal portion on the outdoor side.
An inclined portion is provided, and a space between the horizontal portion and the inclined portion is provided.
Since the R-plane was used, it was possible for the shutter
You can slide.

According to the second aspect, the inclination angle of the lower frame is set to 4 degrees or more.
By setting it to a range of 5 degrees, you can reduce the door opening force
And without significantly increasing the door opening power,
Dispensing force and door opening force are equalized, making it more suitable for practical use.
Set to degree.

According to the third aspect, the side plate of the door pocket is vertically
Attach two door stop stoppers with an interval, and
Guide the door end to the outside when storing the shutter in the topper.
Because it has a sloping surface, the
The direction is automatically changed by being guided by the slope of the stopper.
And can put a shutter.
