Description

  The present invention relates to a screen door for a building opening.

It is known to install a screen door for insectproofing, blindfolding, decoration and the like inside a window frame such as an opening / closing window, for example, a window to be opened, a window to be opened, and a window to protrude.
When the screen door is opened for the purpose of cleaning the window frame or the like, there are some that open the entire screen and some of the screen door. Moreover, when opening a screen door, what is led out to the outside of a screen door is known in addition to what winds up or folds the net.

Regarding the screen door that leads the net to the outside of the screen door, for example, Patent Document 1 (Japanese Patent No. 5420291) describes the following screen device for a building opening (or screen door).
That is, one end of the screen is fixed to one of the upper, lower, left and right sides of the building opening frame, and an operation bar is attached to the other end of the screen. A pair of guide frames are provided along the building opening frame so as to face both sides of the screen and the operation bar, and both ends of the screen and the operation bar are slidably guided by the guide frames.
When a part of the guide frame is cut off at the maximum opening position of the screen in the guide frame and the screen is pressed in the longitudinal direction of the guide frame by the operation bar, the screen is led out of the guide frame from the cut-out portion of the guide frame. .

According to this building opening screen device, the screen can be opened by pushing the screen out of the guide frame by operating the operation bar.
However, this conventional screen device still has the following problems to be solved.
That is, when the operation bar is raised to the maximum opening position of the net, the net hangs down to 1/2 of the vertical height of the entire opening. For this reason, for example, when operating a handle provided in the center of the window lower frame in an opening window, the hand touches the hanging net and is difficult to operate.

The operation bar in the screen device cannot be fixed. Therefore, it is necessary to perform the opening operation of the screen while holding the operation bar.
If a gap occurs due to the tolerance of the net (screen) or the tolerance of the product (screen device for building opening), the net may wrinkle at the gap.
In order to remove the net, it is necessary to remove the operation bar from the notch in the guide frame. Therefore, it is necessary to enlarge the notch, and a cover material that hides the enlarged notch is required. Therefore, not only the cost increases, but when the net is led out from the notch, there is a possibility that the cover material hits the net and the net cannot be opened and closed smoothly.

It consists of a part (vertical frame connecting part) 54.

  The corner block 50 is a plate-like member provided with a substantially U-shaped notch in front view as shown in FIG. That is, the corner block 50 includes a portion (notch portion) cut out between a portion 52 connected to the end portion of the screen door upper frame 12 and a portion 54 connected to the upper end portions of the screen door vertical frame 14 and the vertical frame attachment 24. The cutout portion constitutes a net lead-out portion 53 in the vicinity of the upper end portion of the screen door vertical frame 14. Further, the center part is formed in a curved shape toward the net deriving part 53 side (herein, the indoor side) corresponding to the net deriving part 53 on the opposite side of the net 30 with respect to the net deriving part 53. A net derivation assisting unit 56 is provided.

As will be described later, the net derivation assisting portion 56 facilitates bending of the net 30 curved on the net derivation assisting portion 56 to the indoor side so as to be easily derived when lifting up the movable beam 16. Assistance in derivation for
The shape of the net derivation assisting portion 56 is not limited to the above-described one, and the net 30 is easily derived in a double folded state by the net derivation assisting portion 56 such as a bent surface or a tapered surface. It only has to be able to promote the shape.

Further, the upper frame connecting portion 52 and the vertical frame connecting portion 54 of the corner block 50 are provided with screw holes 52a and 54a, respectively. The screw holes 52a and 54a are formed as long holes as shown in the figure, and the processing holes of the vertical frame attachment 24 attached to the screen door vertical frame 14 are also formed as long holes. These screw holes 52a and 54a absorb construction errors and tolerances of the screen door upper frame 12 and the screen door vertical frame 14, and provide adjustment allowances in the width direction and height direction when they are thermally expanded and contracted. ing.
That is, the corner block 50 has a function as the net derivation portion 53 of the net 30 led out to the indoor side, and also has an adjustment function with respect to the length variation in the screen door vertical frame 14 and the screen door upper frame 12 to be connected. ing.

"Vertical frame cap"
As shown in FIG. 5, the vertical frame cap 60 has a plate-like body 62 that closes the edge portion of the lower end portion of the screen door vertical frame 14, and a protruding portion that is erected on the plate-like body 62 and inserted from the lower end of the screen door vertical frame 14. 64 and a portion extending from the plate-like body 62 are provided with a biasing means, for example, a pin 68 for fitting a coil spring 66 here.
Here, the coil spring 66 has a function of elastically energizing the lower end portion of the inner rail 20 accommodated in the screen door vertical frame 14 and always abutting the upper end portion of the inner rail 20 on the corner block 50.
With this function, even when the upper corner block 50 performs position adjustment, the inner rail 20 can always follow the position adjustment, and no gap is formed between the corner block 50 and the corner block 50.

"Stopper"
A stopper 70 is attached to the screen door vertical frame 14.
6A is a perspective view of the stopper 70 before being attached to the screen door vertical frame 14, and FIG. 6B is a perspective view showing a cross section of the stopper 70 after being attached to the screen door vertical frame 14.
The stopper 70 has a locking portion 72 that locks the movable rail 16 that protrudes and rises toward the passage of the movable rail 16 in the screen door vertical frame 14.
In the present embodiment, as shown in the figure, a protruding portion 64 fitted from the outer surface side of the screen door vertical frame 14 into a mounting hole 14a provided on one side surface of the screen door vertical frame 14, and formed integrally with the protruding portion 64, The passage of the movable bar 16 has a locking portion 72 that protrudes to the inner surface side of the screen vertical frame 14 through which the side end of the net 30 passes.

As shown in FIG. 6B, the stopper 70 includes a columnar portion 14b between the mounting hole 14a and a portion that is adjacent to the mounting hole 14a and is notched in a concave shape from the inner end of the screen door vertical frame 14. And is attached to the screen door vertical frame 14 so as to be held between the locking portions 72.
The locking part 72 is lifted when the screen door is opened, and the rising movable bar 16 is locked by placing it on the stepped portion, thereby preventing the movable bar 16 from further rising.

The mounting position of the stopper 70 is preferably set at about 2/3 of the length (height) between the upper and lower sides of the screen door vertical frame 14. Here, the meaning of “about” is not strictly 2/3 but includes the vicinity thereof, and it is sufficient that the net 30 can maintain three folds with substantially the same length.
That is, by installing the stopper at a position about 2/3 of the length (height) between the upper and lower sides of the screen door frame 14 in this way, the movable bar 16 is lifted with a handle 80 to be described later to lift the screen door 10. When the movable rail 16 is locked to the stopper 70, the net 30 led out indoors from the net lead-out portion 53 of the corner block 50 extends downward in a folded state to the indoor side, and is folded in half. Is substantially the same as the length of the net remaining in the inner rail 20.

In this state, the net 30 is folded in three as a whole, and the length of the net 30 extending downward on the outdoor side is such that the net 30 is fully opened as in the conventional case, that is, all the net 30 extends to the outdoor side. The length of the net 30 extending downward on the outdoor side (1 / 2-1 / 3 of the screen door vertical frame length) is shorter than that in the case of folding in two.
Therefore, the conventional inconvenience of operating the net 30 hanging down indoors as it is opened over the hand that handles the handle of the open window, for example, and supporting the net 30 with the hand separated by hand is eliminated. it can.

  The stopper 70 may be simply formed as a door stop if it is possible to maintain the state where the movable rail 16 is in contact with the stopper 70 due to the weight of the net 30 extending to the outdoor side. If there is a configuration such as snap catch. The stopper mounting means is not limited to the above-described one, and an arbitrary structure can be adopted.

"Toride"
A handle 80 is attached to the movable bar 16. This will be described with reference to FIGS.
FIG. 4 is a perspective view showing the handle 80 attached to the movable beam 16 and the movable beam cap 40 described above.
In the example shown in FIG. 4, the handle 80 is attached to, for example, the longitudinal center of the movable bar 16.
As shown in the figure, the handle 80 includes a handle portion 82 and a locking portion (not shown) that can be snap-locked to the movable bar 16 on the back surface of the handle portion 82.
As shown in FIG. 5, a pair of handles 80 may be provided on both sides of the movable bar 16. In this case, the handle 80 can be provided with the handle fore cap 84 which is also a gap adjusting means, thereby adding the above-described gap adjusting function of the movable crosspiece cap 40.

That is, in FIG. 5, the handle 80 is attached to both ends of the movable rail 16 in the lateral direction, and is structured to be screwed to the movable rail 16 on the bottom surface, for example. In that case, the screw hole is configured as a long hole, and the handle 80 is attached to the movable bar 16 so as to be laterally displaceable.
That is, the clearance (clearance) between the screen door vertical frame 14 and the handle edge cap 84 on the lateral side surface of the handle 80 is adjusted to be as small as possible and attached to the movable bar 16.
As a result, as in the case where the movable bar cap 40 is attached, there is a gap between the screen door vertical frame 14 and the movable bar 16, and there is no backlash and the vertical movement of the movable bar 16 is smooth. Is possible.

  In the present embodiment, the ascending position is set at about 2/3 of the vertical dimension of the screen door vertical frame 14. Therefore, at the position where the movable rail 16 is stopped, the vertical length of the half-folded net 30 led out to the indoor side is substantially equal to the vertical length of the net 30 in the screen door 10. That is, the raising (opening) of the net 30 is stopped at a position where the net 30 descending indoors and the lower end of the net 30 pushed up in the screen frame (the lower end of the movable bar 16) are substantially equal.

For this reason, the lower end position of the net 30 led out to the indoor side can be set higher than in the conventional screen door 10, and therefore the net 30 is opened to open / close the window on the outside, or to clean the net 30. When doing so, the troublesomeness that the net 30 led out indoors overlaps on the hand can be greatly reduced.
When closing the screen door, if the movable rail 16 is lowered, the net 30 led out from the net lead-out portion 53 of the corner block 50 is returned to the original state even if it is pulled back into the screen door frame.

Next, the case where the net 30 is replaced in the screen door 10 will be described.
