The lower end of the side upper edge 320d is formed at a position lower than the lower end of the glass side upper edge 320g. Further, in the vertical inner peripheral surface facing portion 32a, the portion 320j on the surface material side with respect to the engagement notch 320 is formed higher than the portion 320k on the glass side.

  As shown in FIGS. 6 and 10A, the connecting member 5 has a flat, substantially rectangular parallelepiped shape having a low height, and is provided on one side in the longitudinal direction of the connecting member 5. The projecting portion 50 protruding from the inner peripheral surface facing portion 32a to the outer peripheral side of the frame forming frame 3 and the connecting member inserted portion 31f of the lateral frame member 31 are provided on the other side in the longitudinal direction. An insertion portion 51 that is inserted along the longitudinal direction in a press-fit state, and the insertion portion 51 is formed longer than the protruding portion 50. An intermediate portion 52 that connects the protrusion 50 and the insertion portion 51 is provided between the protrusion 50 and the insertion portion 51.

  The connecting member 5 is provided 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 forming frame 3 and the projecting portion 50 is located on the outer peripheral side of the vertical frame member 32. 5 is rotated about a virtual axis 321 along the longitudinal direction, and the intermediate portion 52 is inserted into the engagement notch 320. In a state in which the intermediate portion 52 is inserted into the engagement notch portion 320 and the flat insertion portion 51 is substantially horizontal, the protruding portion 50 and the insertion portion 51 each have an opposing protrusion opposing the vertical inner peripheral surface opposing portion 32a. Parts 50a and 51a are provided, respectively.

  As shown in FIG. 10B, the opposing protrusions 50a provided on the protrusion 50 are provided at both sides in the anticipated direction than the intermediate portion 52 and at three places protruding below the intermediate portion 52. As shown in FIG. 10C, the opposed protrusions 51a provided on the insertion portion 51 are on both sides in the expected direction than the intermediate portion 52, and are opposed to the opposed protrusions 50a of the protrusion 50. And are provided at positions facing each other in the expected direction. The distance between the facing protrusion 50a of the protrusion 50 and the facing protrusion 51a of the insertion portion 51 in the expected direction, that is, the width W3 in the longitudinal direction of the intermediate portion 52 is substantially the same as the thickness t of the vertical frame member 32, or slightly smaller. It is formed large.

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

  As shown in FIG. 6, when attaching the connecting member 5 to the engagement notch 320, the longitudinal direction of the connecting member 5 is set so as to be along the left-right direction orthogonal to the expected surface of the vertical inner peripheral surface facing portion 32a. At the same time, it is arranged so that the intermediate portion 52 is located above the engagement notch portion 320 above the vertical inner peripheral surface facing portion 32a in the left-right direction. At this time, the connecting member 5 is oriented such that the opposing projections 50a of the projections 50 are located on both sides in the expected direction and on the lower side.

  Next, as shown in FIG. 11, the connecting member 5 is inserted around the virtual axis 321 into the engagement notch 320 while being tilted so that the glass side is lower than the surface material side. At this time, the opposing projection 50a of the projection 50 is located on the left side of the vertical inner peripheral surface opposing portion 32a, and the opposing projection 51a of the insertion portion 51 is located on the right side of the vertical inner peripheral surface opposing portion 32a. Insert.

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

When the insertion portion 51 is substantially horizontal, the connecting member 5 has the vertical inner peripheral surface facing portion 32a located between the facing projection 50a of the projection 50 and the facing projection 51a of the insertion portion 51. The three opposing protrusions 50a and the two opposing protrusions 51a of the insertion portion 51 restrict the movement in the left-right direction. Further, in this state, the movement of the intermediate portion 52 in the expected direction is restricted by the surface material side lower edge 320e and the glass side lower edge 320h of the engagement notch 320, and the intermediate portion 52 is controlled by the bottom edge 320c and the glass side connection edge 320i. Vertical movement is restricted. In particular, in the case of the present embodiment, since 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 expected direction and rotation is restricted, the connecting member 5 is Even if a gap is created between the fore-edge 31j of the horizontal frame member 31 and the vertical frame member 32 in a direction in which the horizontal frame member 31 is removed from the member 31, the horizontal frame member 31 and the vertical frame member 32 are not immediately separated.
It does not come off from the joint notch 320.

  In the state where the connecting member 5 is engaged with the engagement notch 320 of the vertical frame member 32, as shown in FIGS. 12 and 13, the fore end 31j of the horizontal frame member 31 is moved to the right side of the vertical inner peripheral surface facing portion 32a. Join so as to make 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-fit 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 member 31 and the vertical frame member 32 are joined by the connecting member 5, the horizontal glass of the horizontal frame member 31 is positioned between the remaining vertical glass facing portion 32c and the overhang portion 32e of the vertical bonding portion 32d. The facing part 31c is inserted. At this time, the width W4 (FIG. 7) from the surface on the surface material side of the horizontal glass facing portion 31c to the tip of the horizontal glass contact piece 31i is equal to the glass side surface of the vertical glass facing portion 32c and the surface of the overhang portion 32e. It is almost the same as 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 of the vertical glass facing portion 32c where the vertical glass contact piece 32g is cut off, and the horizontal glass contact piece 31i of the horizontal frame material 31 is attached to the vertical frame material 32. Abuts on the surface material side of the protruding portion 32e that protrudes on the inner peripheral side of the vertical bonding portion 32d.

  The end of the horizontal bonding portion 31e of the horizontal frame member 31 is inserted into the concave portion 32h provided in the vertical frame member 32, and the horizontal bonding portion 31e of the horizontal frame member 31 and the vertical bonding portion 32d of the vertical frame member 32 are inserted. Are connected in a rectangular shape. In this manner, the horizontal frame member 31 and the vertical frame member 32 are joined, so that the horizontal frame member 31 moves in any of the prospective directions and the vertical direction with respect to the vertical frame member 32. Is regulated, and rotation about the virtual axis 321 is also regulated. At this time, rotation of the connecting member 5 in which the insertion portion 51 is inserted into the connecting member inserted portion 31f of the horizontal frame member 31 is also restricted around the virtual axis 321. In particular, since the clockwise rotation of the connecting member 5 as viewed from the insertion portion 51 toward the protruding portion 50 is regulated, the horizontal frame member 31 and the vertical frame member 32 joined by the connecting member 5 Securely joined.

  Two frame forming 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 from both sides of the door body 1c so as to sandwich the outer peripheral portion 20a of the glass plate 20 provided in the opening 1e. The door 1 is formed by attaching the outer peripheral portion 20a of the glass plate 20 to the horizontal glass abutting piece 31i of the horizontal frame material 31 and the vertical glass abutting piece 32g of the vertical frame material 32 with the adhesive 4 while attaching. I do.

  According to the connection structure and the door 1 of the present embodiment, the connection member 5 that connects the horizontal frame member 31 and the vertical frame member 32 is engaged with the engagement notch 320 of the vertical frame member 32 and the horizontal frame. The horizontal frame member 31 and the vertical frame member 32 are connected by being inserted into the connecting member inserted portion 31f of the member 31. Therefore, the horizontal frame member 31 and the vertical frame member 32 can be easily connected without using a tool or the like.

  The connecting member 5 is releasably engaged with the engagement 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 in which the horizontal frame member 31 and the vertical frame member 32 are connected, the rotation of the connecting member 5 is restricted and does not come off from the vertical frame member 32. For this reason, the connecting structure which can easily connect the horizontal frame member 31 and the vertical frame member 32 in a state where the horizontal frame member 31 and the vertical frame member 32 are hard to separate, and the connecting structure in which the horizontal frame member 31 and the vertical frame member 32 are hard to separate. It is possible to provide the door 1 having the frame configuration frame 3 provided.

  In a state in which the horizontal frame member 31 and the vertical frame member 32 are connected, the horizontal frame member 31 into which the connecting member 5 is inserted is locked by the vertical frame member 32, and the rotation of the horizontal frame member 31 is restricted. Therefore, the rotation of the connecting member 5 can be more reliably restricted.

  The horizontal frame member 31 is locked to the vertical frame member 32 by a 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 made of glass. Since it has a width enough to face the outer peripheral portion 20a of the plate 20, it is possible to more reliably restrict the rotation than when the edges are engaged with each other. In particular, in the case of the present embodiment, since the horizontal glass facing portion 31c of the horizontal frame material 31 overlaps the vertical glass facing portion 32c of the vertical frame material 32 in the expected direction and rotation is restricted, the connecting member 5 is Even if a gap is generated between the fore-edge 31j of the horizontal frame member 31 and the vertical frame member 32 in a direction in which the horizontal frame member 31 is removed from the member 31, the horizontal frame member 31 and the vertical frame member 32 are not immediately separated.

  In the above embodiment, the engagement notches 320 provided in the left and right vertical frame members 32 are formed in an overlapping shape when the respective vertical inner peripheral surface opposing portions 32a face each other, and the connecting members are in the same direction. Although the example in which the engagement is performed when the rotation is performed and the engagement is released is described, the invention is not limited thereto. For example, as shown in FIG. 14, if the left and right vertical frame members 32 are provided with engagement notches 320 having shapes in which the surface material side and the glass side are reversed in the expected direction, the engagement of the connecting member 5 is prevented. 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. For this reason, the left and right vertical frame members 32 and the connecting members 5 engaged with each other restrict the rotation in the direction in which the engagement is released, so that the vertical frame members 32 are connected to both sides of the horizontal frame member 31. By simply doing so, the horizontal frame member 31 and the vertical frame member 32 can be connected to each other more easily without providing a rotation restricting portion on the vertical frame member 32 and the horizontal frame member 31. Also in this case, as in the above-described embodiment, if the vertical frame member 32 and the horizontal frame member 31 are provided with a restricting portion that restricts the rotation of each other, the horizontal frame member 31 and the vertical frame member 32 can be formed. Can be connected more easily.

  In the above-described embodiment, an example has been described in which the protrusion 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. The horizontal frame member 31 and the vertical frame member 32 may be connected by engaging the protrusion 50 with the horizontal frame member 31 and inserting the insertion portion 51 into the vertical frame member 32.

  In the above-described embodiment, the door to which the frame unit 2 is attached has been described by taking a door as an example. However, the door is not limited to the door, and may be a sliding door or a sliding door. The frame unit may be provided directly on a wall or the like. In addition to the frame, if the two frame members are joined by a connecting member, for example, as shown in FIG. 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 member 12a is inserted and connected to the horizontal frame member 12b, the horizontal frame member 12b is inserted between the fin portions 12c of the vertical frame member 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 regulated 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-described embodiment, a glass plate has been described as an example of the face material. However, the present invention is not limited to this. For example, a polycarbonate plate may be used.

  Note that the above embodiment is for facilitating the understanding of the present invention, and is not for limiting and interpreting the present invention. The present invention can be changed and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.

This embodiment includes at least the following inventions.

The other frame material of the two frame materials has an inserted portion into which the connecting member is inserted along the longitudinal direction at an end in the longitudinal direction, and the connecting member has The rotation is restricted by being engaged with the cutout portion of the one frame member and being inserted into the inserted portion of the other frame member. .

  According to such a connection structure, the connection member that connects the two frame members is engaged with the cutout portion of one of the frame members and is inserted into the inserted portion of the other frame member so that the two frame members are connected. Are connected. Therefore, it is possible to easily connect the two frame members without using a tool or the like. The connecting member is releasably engaged with the notch portion of one of the frame members by being rotated, and the rotation is regulated by connecting the two frame members. In a state where the members are connected, the rotation of the connecting member is restricted and does not come off from one of the frame members. For this reason, it is possible to provide a connection structure that can easily connect the two frame members in a state in which the two frame members are less likely to come off.

  In such a connection structure, in a state where the one frame material and the other frame material are connected, the other frame material is locked to the one frame material, and rotation of the other frame material is restricted. It is characterized by having been done.

  According to such a connection structure, in a state where one frame member and the other frame member are connected, the other frame member into which the connecting member is inserted is locked by the one frame member, and the other frame member is locked. Since the rotation of the member is restricted, it is possible to more reliably restrict the rotation of the connecting member.

  In such a connection structure, the one frame member forming the pair and the other frame member forming the pair are connected to each other to form a frame body capable of contacting an outer peripheral portion of the face material, And the other frame material has a face material facing portion facing the outer peripheral portion of the face material along a longitudinal direction of each of the frame materials, and the other frame material is the other frame material of the other frame material. The face material facing portion is locked to the one frame material.

  According to such a connection structure, the other frame material is locked to the one frame material at the face material facing portion facing the outer peripheral portion of the face material along the longitudinal direction. Has a width enough to face the outer peripheral portion of the face material, so that it is possible to more reliably restrict the rotation than when the edges are engaged with each other. Further, since the two frame members are locked at a portion having a predetermined width, even if the relative positions of the two frame members are shifted, it is possible to prevent the two frame members from being immediately separated.

  In such a connection structure, the notch portion is provided in each of the pair of the one frame members with which the connection member is engaged, and the cutout portions are provided in the facing portions facing each other with an interval therebetween, and The connecting members respectively engaged with the notches have opposite rotation directions when the engagement with the notches is released.

  According to such a connection structure, the pair of one frame member and the other frame member whose both end portions are connected by the connection member are connected to the notch portion in the two connection members respectively inserted into both end portions. Since the directions of rotation at the time of disengagement are opposite to each other, simply connecting the pair of one frame member and the other frame member causes the two connecting members to be disengaged from the notch. To regulate each other. For this reason, it is possible to more reliably regulate the rotation of the connecting member, and to form a more securely connected frame.

  In this connection structure, the one frame member forming a pair and the other frame member forming a pair are connected to form a frame, and the pair of one frame members are engaged with the connection member. The notch is provided in each of the facing portions facing each other at an interval, and the connecting member engaged with the notch of the facing facing portion is engaged with the notch. The directions of the rotations when released are opposite to each other.

  According to such a connection structure, one of the pair of frame members and the other frame member whose both ends are connected by the connection members are connected to the notch portions in the two connection members inserted at both ends. Since the directions of rotation when the engagement is released are opposite to each other, the two connecting members are released from the engagement with the notch portions only by connecting the pair of one frame member and the other frame member. The rotation in the direction is regulated by each other. For this reason, the connection member can be more reliably connected only by engaging the connecting member with one of the frame members and inserting it into the other frame member without providing a portion for restricting the rotation of the two frame members. is there.

Further, the door body includes the frame body connected by the connection structure, and a door body to which the frame body is attached.
According to such a door body, it is possible to provide a door body provided with a frame body in which two frame members are hardly detached.
