Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for connecting the ends of a sliding door, particularly a frame and a side frame of a screen door.

Traditionally, the solid stile and side stile of a screen door are connected by driving corner beads, but the stile is only supported by the friction between the corner bead and the side wall of the stile, and the tension of the net, so it can be used for a long time. The drawback was that the overall shape of the screen door was distorted.

Additionally, there are known devices in which the corner bead and the stile, or each stile are connected by tightening and fixing them with screws, but in this case, screw holes must be formed in the longitudinal direction of the stile. The screw holes require bulky material, resulting in high costs.

Therefore, a connection structure as shown in Japanese Utility Model Publication No. 45-6216 has been proposed.

That is, as shown in Fig. 1, a hole c is drilled in the horizontal wall b of the horizontal stile a, a member e having a screw hole d is press-fitted into this hole c, and a screw h is inserted through the vertical wall g of the rigid stile f into the screw hole d. Screw together the horizontal stile a and the rigid stile f.
are connected.

In this way, there is no need to form screw holes in the longitudinal direction of the frame, so material costs can be reduced, resulting in lower costs.

However, with this connection structure, when a force (arrow F ₁ ) that tries to distort the screen door acts, a tensile force F ₂ acts on the member e toward the rigid frame f, and this tensile force F ₂
is supported by the end portion b' of the horizontal wall b of the stile a, rather than the hole c.

For this reason, if the end portion b' is short, this portion b' will break due to the tensile force _F2 (in the case of a screen door, it is particularly easy to break because the wall thickness is thin).
The end portion b' must be made longer.

Therefore, the distance L between the member end face e′ and the vertical wall g
becomes longer, and when the screw h is tightened, the vertical wall g deforms and protrudes toward the horizontal stile a side. As shown in Fig. 2, both side walls f' and f' of the rigid stile f expand and deform to the side. Not only does this overhang the sliding door, it looks bad, but when the sliding door is opened and closed, the deformed part interferes with the other sliding door, making it impossible to open and close it smoothly. This is particularly noticeable in the case of screen doors because each wall of the stile is thin.

In addition, in the case of a screen door, the tensile force of the screen is strong, so this tensile force causes a rotational force to act on the stile, and when tightening the screws, the stile rotates as the screws rotate. Therefore, if the directions of the two rotational forces match, the stile will rotate and the above-mentioned expansion deformation will become even larger, making it impossible to open and close the screen door smoothly.

The present invention was developed in view of the above circumstances, and its purpose is to provide a stile connecting device that can be firmly connected to prevent the entire sliding door from being distorted, save materials, and prevent the stile from expanding and deforming. The goal is to provide the following.

Embodiments of the present invention will be described below with reference to FIG. 3 and subsequent figures.

Figure 3 is a front view of the screen door, with upper stile 1 and lower stile 2.
A mesh 5 is stretched over the surrounding frames 1, 2, 3, and 3 of a frame assembly 4 which is made up of a square frame and a pair of hard frames 3, 3.

A through hole 7 is formed in the horizontal wall 6 of the lower stile 2, and a fitting body 8 is fitted into the through hole 7 so as not to fall off and to be movable in the longitudinal direction.

The fitting body 8 includes a main body portion 10 having a diameter slightly larger than the width of the through hole 7 and having a screw hole 9;
A plate-like part 11 that is continuous with the plate-like part 11 and has the same width as the width of the through-hole 7 , and a plate-like base part 12 that is continuous with the plate-like part 11 and has a width wider than the width of the through-hole 7 . A flat portion 10a facing the plate-like portion 11 is formed.
A step 13 is formed by one end surface 11a in the longitudinal direction of the main body 10, and the distance _S1 between the step 13 and the one end surface 10b in the longitudinal direction of the main body 10 is parallel to the inner end surface 7a of the one longitudinal direction of the through hole 7. Distance from one longitudinal end surface 6a of wall 6
It is the same as S ₂ .

Further, one longitudinal end surface 10b of the main body portion 10 and one longitudinal end surface 12a of the base portion 12 are located at the same position.

Then, the main body part 10 is pushed into the through hole 7 while being elastically deformed, and the plate-like part 11 is fitted into the through hole 7, so that the fitting body 8 can be freely slid into the through hole 7 in the longitudinal direction as shown in FIG. Fit and install. In this state, the base 12 comes into contact with the horizontal wall 6, and the main body 10 is restored to its original state with a diameter slightly larger than the width of the through hole 7, so the fitting body 8 does not fall out of the through hole 7 and is temporarily fixed. This effect makes it easier to screw together the screws, which will be described later.

From this state, when the screw 16 is screwed into the screw hole 9 through the screw insertion hole 15 formed in the vertical wall 14 of the rigid frame 3, the tightening force of the screw 16 will cause the fitted body 8 to
is slid and drawn toward the vertical wall 14 side, so that one end surface 10b of the main body part comes into contact with the vertical wall 14, and the step part 13 comes into contact with the inner end surface 7a of one side of the through hole 7, so that the lower stile 2 and the hard stile 3 are brought into contact with each other.
and are tightened together.

As described above, since one end surface 10b of the main body part is connected with the screw 16 so as to be in contact with the vertical wall 14 of the rigid frame 3, the lower frame 2 and the rigid frame 3 can be firmly connected, and the entire screen band will not be distorted. .

Further, since there is no need to form screw holes in the longitudinal direction of the lower stile 2, materials can be saved and costs can be reduced.

Further, even if the screw 16 is strongly tightened, the one end surface 10b of the main body portion is in contact with the vertical wall 14, so the vertical wall 1
4 is not deformed, and both side walls 3a of the rigid frame 3,
3a (not shown) does not expand and deform, so it does not interfere with the sliding door when opening and closing the screen door, making opening and closing smooth and without damaging the appearance.

Also, the screw hole 9 becomes a loose hole and the screw 16
When it becomes impossible to screw the fitting body 8 into place, the fitting body 8 can be replaced.

In addition, as shown in FIG.
2'a, the fitting body 8 may be easily drawn toward the vertical wall 14, and the base portion 12 may extend up to the stepped portion 13 as shown in FIG.

In addition, in the above embodiment, the lower stile 2 and the hard stile 3 of the screen door are
Although a case has been described in which the two are connected, the present invention is not limited to this, and it goes without saying that a solid stile such as a shoji door and a horizontal stile may be connected.

The present invention is as described above, and the horizontal stile and the stile 3 are connected by the screws 16 so that the contact surface formed on the one end surface 10b of the main body part 10 abuts the vertical wall 14 of the stile 3. It can be firmly connected and the entire sliding door will not be distorted.

Furthermore, since there is no need to form screw holes in the longitudinal direction of the stile, materials can be saved and costs can be reduced.

In addition, even if the screw 16 is strongly tightened, the contact surface formed on one end surface 10b of the main body portion 10 is in contact with the vertical wall 14, so the vertical wall 14 will not be deformed and both side walls of the rigid frame 3 will expand. Since it does not deform, the sliding door does not interfere with other sliding doors when opening and closing, making opening and closing smooth and without damaging the appearance.
