The horizontal frame member 31 is provided on the outer peripheral side of the frame constituent frame 3 from the inner peripheral surface facing portion 32a and on the other side in the longitudinal direction. It has an insertion portion 51 that is inserted in a press-fitted state along the longitudinal direction, and the insertion portion 51 is formed longer than the protruding portion 50. An intermediate portion 52 connecting the protruding portion 50 and the inserting portion 51 is provided between the protruding portion 50 and the inserting portion 51.

The connecting member 5 is a connecting member at a position where the insertion portion 51 is located on the inner peripheral side of the vertical frame member 32 of the framed frame constituent frame 3 and the protruding portion 50 is located on the outer peripheral side of the vertical frame member 32. The intermediate portion 52 is inserted into the engaging notch 320 by rotating 5 around the virtual shaft 321 along the longitudinal direction. In a state where the intermediate portion 52 is inserted into the engaging notch 320 and the flat insertion portion 51 is substantially horizontal, the protrusion 50 and the insertion portion 51 each face a facing protrusion facing the vertical inner peripheral surface facing portion 32a.

The distance between the facing protrusions 50a of the protruding portion 50 and the facing protrusions 51a of the insertion portion 51 in the prospective direction, that is, the width W3 in the longitudinal direction of the intermediate portion 52 is substantially the same as or slightly equal to the thickness t of the vertical frame member 32. It is formed large in.

The connecting member 5 is rotated around the virtual axis 321 with the longitudinal direction of the connecting member 5 along the virtual axis 321 (FIG. 6) orthogonal to the prospective surface of the vertical inner peripheral surface facing portion 32a to form a vertical frame. It is attached to the material 32. The state in which the connecting member 5 is attached will be described with reference to FIG. 11 when the connecting member 5 is attached to the vertical frame member 32 on the left side. In FIG. 11, the connecting member 5 is visible when viewed from the cross section of the intermediate portion 52 when the connecting member 5 is cut by AA or BB in FIG. 10A and from AA or BB. It is shown only by the facing protrusions 50a and 51a, and other parts are omitted.

As shown in FIG. 6, when the connecting member 5 is mounted on the engaging notch 320, the longitudinal direction of the connecting member 5 is along the left-right direction orthogonal to the prospective surface of the vertical inner peripheral surface facing portion 32a. The intermediate portion 52 is arranged so as to be located above the vertical inner peripheral surface facing portion 32a and above the engaging notch portion 320 in the left-right direction. At this time, the connecting member 5 is directed so that the facing protrusions 50a of the protrusions 50 are located on both sides and the lower side in the prospective direction.

Next, as shown in FIG. 11, the connecting member 5 is inserted into the engaging notch 320 while being rotated and tilted around the virtual shaft 321 so that the glass side is lower than the surface material side. At this time, the facing protrusion 50a of the protruding portion 50 is located on the left side of the vertical inner peripheral surface facing portion 32a, and the facing protrusion 51a of the insertion portion 51 is located on the right side of the vertical inner peripheral surface facing portion 32a. I will insert it.

Next, after the upper edge 52a on the glass side of the intermediate portion 52 moves below the glass side connecting edge 320i, the virtual shaft 321 is used so that the portion of the connecting member 5 on the surface material side is lowered. Rotate it around and move it to the glass side while making it closer to horizontal. The rotation direction at this time is counterclockwise when viewed from the insertion portion 51 toward the protrusion 50.

In the connecting member 5, when the insertion portion 51 becomes substantially horizontal, the vertical inner peripheral surface facing portion 32a is located between the facing protrusion 50a of the protruding portion 50 and the facing protrusion 51a of the insertion portion 51, and the protruding portion 50 The movement in the left-right direction is restricted by the three facing protrusions 50a and the two facing protrusions 51a of the insertion portion 51. Further, in this state, the intermediate portion 52 is restricted from moving in the prospective direction by the surface material side lower edge 320e and the glass side lower edge 320h of the engaging notch portion 320, and the bottom edge 320c and the glass side connecting edge 320i. Vertical movement is restricted. In particular, in the case of the present embodiment, the horizontal glass facing portion 31c of the horizontal frame member 31 overlaps the vertical glass facing portion 32c of the vertical frame member 32 in the prospective direction to restrict rotation, so that the connecting member 5 is a horizontal frame. Even if a gap is formed between the edge 31j of the horizontal frame material 31 and the vertical frame material 32 in the direction of being detached from the material 31, the horizontal frame material 31 and the vertical frame material 32 are not immediately separated.
It does not come off from the joint notch 320.

With the connecting member 5 engaged with the engaging notch 320 of the vertical frame member 32, as shown in FIGS. 12 and 13, the edge 31j of the horizontal frame member 31 is placed on the right side of the vertical inner peripheral surface facing portion 32a. Join so that they are in contact with the prospective surface. At this time, the insertion portion 51 of the connecting member 5 is inserted into the connecting member inserted portion 31f of the horizontal frame member 31 in a press-fitted state along the longitudinal direction of the horizontal frame member 31. At this time, the connecting member 5 is engaged with the engaging notch 320 of the vertical frame member 32 and is inserted into the connecting member inserted portion 31f of the horizontal frame member 31.

When the horizontal frame material 31 and the vertical frame material 32 are joined by the connecting member 5, the horizontal glass of the horizontal frame material 31 is placed between the remaining vertical glass facing portion 32c and the overhanging portion 32e of the vertical adhesive portion 32d. The facing portion 31c is inserted. At this time, the width W4 (FIG. 7) from the surface material side surface of the horizontal glass facing portion 31c to the tip of the horizontal glass contact piece 31i is the glass side surface of the vertical glass facing portion 32c and the surface of the overhanging portion 32e. It almost coincides with the distance L3 (FIG. 7) from the surface on the material side. Therefore, the horizontal glass facing portion 31c is brought into contact with the portion where the vertical glass contact piece 32g of the vertical glass facing portion 32c is cut off, and the horizontal glass contact piece 31i of the horizontal frame member 31 is brought into contact with the vertical frame member 32. It comes into contact with the surface material side of the overhanging portion 32e overhanging on the inner peripheral side of the vertically adhering portion 32d.

Further, the end portion of the horizontal adhesive portion 31e of the horizontal frame material 31 is inserted into the recess 32h provided in the vertical frame material 32, and the horizontal adhesive portion 31e of the horizontal frame material 31 and the vertical adhesive portion 32d of the vertical frame material 32 are inserted. And are connected in a rectangular shape. By joining the horizontal frame material 31 and the vertical frame material 32 in this way, the horizontal frame material 31 moves with respect to the vertical frame material 32 in either the prospective direction or in the vertical direction. Is regulated, and rotation around the virtual axis 321 is also regulated. At this time, the rotation of the connecting member 5 in which the inserting portion 51 is inserted into the connecting member inserted portion 31f of the horizontal frame member 31 and the rotation around the virtual shaft 321 are also restricted. In particular, the horizontal frame member 31 and the vertical frame member 32 joined by the connecting member 5 are more likely to rotate in the connecting member 5 in a clockwise direction when viewed from the insertion portion 51 toward the protruding portion 50. It is securely joined.

Two frame constituent frames 3 in which the upper and lower horizontal frame members 31 and the left and right vertical frame members 32 are joined are used, and the outer peripheral portion 20a of the glass plate 20 provided in the opening 1e is sandwiched from both sides of the door body 1c. The door 1 is formed by adhering the outer peripheral portion 20a of the glass plate 20 to the horizontal glass contact piece 31i of the horizontal frame material 31 and the vertical glass contact piece 32 g of the vertical frame material 32 with an adhesive 4. do.

According to the connecting structure and the door 1 of the present embodiment, the connecting member 5 connecting the horizontal frame member 31 and the vertical frame member 32 is engaged with the engaging notch 320 of the vertical frame member 32 and the horizontal frame. The horizontal frame material 31 and the vertical frame material 32 are connected by being inserted into the connecting member inserted portion 31f of the material 31. Therefore, it is possible to easily connect the horizontal frame member 31 and the vertical frame member 32 without using a tool or the like.

The connecting member 5 is rotatably engaged with the engaging notch 320 of the vertical frame member 32 by being rotated, and is rotated by connecting the horizontal frame member 31 and the vertical frame member 32. Therefore, in a state where the horizontal frame member 31 and the vertical frame member 32 are connected, the rotation of the connecting member 5 is restricted and the connecting member 5 does not come off from the vertical frame member 32. Therefore, a connecting structure that allows the horizontal frame material 31 and the vertical frame material 32 to be more easily connected, and a connection structure that allows the horizontal frame material 31 and the vertical frame material 32 to be more difficult to come off. It is possible to provide a door 1 having a framed frame 3.

Further, in a state where the horizontal frame material 31 and the vertical frame material 32 are connected, the horizontal frame material 31 into which the connecting member 5 is inserted is locked to the vertical frame material 32, and the rotation of the horizontal frame material 31 is restricted. Therefore, it is possible to more reliably regulate the rotation of the connecting member 5.

Further, the horizontal frame member 31 is locked to the vertical frame member 32 by the horizontal glass facing portion 31c facing the outer peripheral portion 20a of the glass plate 20 along the longitudinal direction, and the horizontal glass facing portion 31c is the glass. Since it has a width sufficient to face the outer peripheral portion 20a of the plate 20, it is possible to regulate the rotation more reliably than when the edges are engaged with each other, for example. In particular, in the case of the present embodiment, the horizontal glass facing portion 31c of the horizontal frame member 31 overlaps the vertical glass facing portion 32c of the vertical frame member 32 in the prospective direction to restrict rotation, so that the connecting member 5 is a horizontal frame. Even if a gap is formed between the edge 31j of the horizontal frame material 31 and the vertical frame material 32 in the direction of being detached from the material 31, the horizontal frame material 31 and the vertical frame material 32 are not immediately separated.

In the above embodiment, the engaging notch portions 320 provided in the left and right vertical frame members 32 are formed in an overlapping shape when the respective vertical inner peripheral surface facing portions 32a face each other, and the connecting members are formed in the same direction. An example of engaging and disengaging when rotated to the above has been described, but the present invention is not limited to this. For example, as shown in FIG. 14, if the left and right vertical frame members 32 are provided with an engaging notch 320 having a shape in which the surface material side and the glass side are inverted in the prospective direction, the connecting member 5 is engaged. The direction of rotation to be released can be reversed between the left vertical frame member 32 side and the right vertical frame member 32 side. Therefore, since the left and right vertical frame members 32 and the engaging member 5 regulate the rotation in the direction in which the engagement is released from each other, the vertical frame members 32 are connected to both sides of the horizontal frame member 31. It is possible to connect the horizontal frame member 31 and the vertical frame member 32 more easily without disconnecting the vertical frame member 32 and the horizontal frame member 31 without providing a rotation restricting portion. Also in this case, as in the above embodiment, if the vertical frame material 32 and the horizontal frame material 31 are connected to each other and a restricting portion for restricting mutual rotation is provided, the horizontal frame material 31 and the vertical frame material 32 are provided. It is possible to connect them more easily.

In the above embodiment, an example in which the protruding portion 50 is engaged with the vertical frame member 32 and the insertion portion 51 is inserted into the horizontal frame member 31 to connect the horizontal frame member 31 and the vertical frame member 32 has been described. The protrusion 50 may be engaged with the horizontal frame member 31, and the insertion portion 51 may be inserted into the vertical frame member 32 to connect the horizontal frame member 31 and the vertical frame member 32.

In the above embodiment, the door body to which the frame unit 2 is attached has been described by taking a door as an example, but the door is not limited to the door, and a sliding door, a hinged door, or the like may be used as a shoji screen. Further, the frame unit may be provided directly on a wall or the like. Further, not limited to the frame, if the configuration is such that two frame materials are joined by a connecting member, for example, as shown in FIG. 15, the vertical frame material 12a of the frame body 12 that supports the single pulling shoji 11 suspended above is shown. And the horizontal frame member 12b may be connected by the connecting member 5. In this case, when the connecting member 5 engaged with the vertical frame material 12a is inserted into the horizontal frame material 12b and connected, the horizontal frame material 12b is inserted between the fin portions 12c of the vertical frame material 12a. The side wall portion 12d of the horizontal frame member 12b engages with the fin portion 12c of the vertical frame member 12a. Since the rotation of the horizontal frame member 12b is restricted by this engagement, the rotation of the connecting member 5 is restricted, and the vertical frame member 12a and the horizontal frame member 12b are more reliably connected.

In the above embodiment, a glass plate has been described as an example of the face material, but the present invention is not limited to this, and a polycarbonate plate or the like may be used.

It should be noted that the above embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.
