Description

  The present invention relates to a joinery, and more particularly, to a joinery in which a face material is held on a frame-like member via a pressing member.

  In order to hold a face material such as a window glass on a frame-like member such as an opening frame or a ridge, it is common to apply a ledge member. The pushing edge member is bent in a substantially right angle direction from an engagement plate portion arranged along the prospective surface of the frame-shaped member, and a base end portion of the engagement plate portion, and is frame-shaped along the direction of finding from the prospective surface of the frame-shaped member. A face material support plate protruding inward of the member, and the first engagement portion and the second engagement portion of the engagement plate portion are used as the first engagement receiving portion and the second engagement receiving portion of the frame-like member. It is detachably attached to the frame-like member by being brought into contact with the portion.

  The first engaging portion of the pushing edge member is a distal end portion of the engaging plate portion along the longitudinal direction, and the second engaging portion is defined as a portion that is located on the proximal end side of the engaging plate portion from the first engaging portion. It is the part which protruded toward the direction which leaves | separates. The first engagement receiving portion and the second engagement receiving portion of the frame-shaped member are each projected from the prospective surface of the frame-shaped member and then bent toward the directions close to each other. A storage space along the longitudinal direction is formed between each.

  When attaching the pressing edge member to the frame-like member, first, the first engaging portion of the pressing edge member is inserted into and brought into contact with the first engagement receiving portion of the frame-like member.

  In recent joinery, what applied the frame-shaped member which consists of two parts mutually connected through the heat insulating material is provided. According to this type of joinery, heat transfer along the prospective direction of the frame-shaped member is limited by the heat insulating material, and therefore there is an advantage that it is possible to prevent the occurrence of condensation on the surface of the frame-shaped member. .

  In the joinery to which the frame-like member that restricts heat transfer is applied, it is needless to say that it is preferable to provide the edge member so that it does not become a heat transfer element. In other words, if both the first engagement receiving portion and the second engagement receiving portion are provided only in one part of the frame-shaped member and the pressing member is not disposed so as not to cross the heat insulating material, the heat insulation of the frame-shaped member is performed. There is a risk that the sex will be impaired.

  However, when both the first engagement receiving portion and the second engagement receiving portion are provided only in one part of the frame-shaped member, a large distance between these cannot be ensured. The inclination angle of the pressing member when the first engaging portion of the pressing member is inserted between the prospective surface and the first engagement receiving portion must be increased. When the inclination angle of the pressing edge member increases, the amount of movement of the face material support plate portion in the direction of approaching the face material also increases. Therefore, mutual interference between the face material support plate portion and the face material is caused, and the frame member There is a possibility that the attaching / detaching operation of the pressing edge member becomes difficult.

  In addition, when it is considered to apply an injection type as a heat insulating material disposed in the housing portion of the frame-shaped member, a frame shape is formed between the opening edge of the housing portion and the first engagement receiving portion. It is necessary to secure a partition surface extending along the prospective surface of the member. This is because, when the first engagement receiving portion is provided so as to have a continuous plane with respect to the opening edge portion of the accommodating portion, the heat insulating material injected into the accommodating portion causes the first engagement receiving portion to be affected by the surface tension. Therefore, a situation of leakage to the outside is caused, so that a partition surface is secured between the opening edge portion of the housing portion and the first engagement portion to block the movement of the heat insulating material. However, when a partition surface is secured between the opening edge of the housing portion and the first engagement receiving portion, the distance between the first engagement receiving portion and the second engagement receiving portion is further shortened. This leads to a situation in which the inclination angle of the pressing member is further increased when the first engaging portion of the pressing member is inserted between the prospective surface of the frame-shaped member and the first engagement receiving portion. Connected.

  In view of the above circumstances, the present invention facilitates the attaching and detaching operation of the pressing member with securing the heat insulating property to the frame-like member in which one part and the other part are connected via the heat insulating material. And it aims at providing the fitting which can be performed reliably.

In order to achieve the above object, a joinery according to the present invention has one part and the other part connected to each other via a heat insulating material, and the first engagement receiving part and the second engagement are provided in the one part. It has a frame-like member provided with a receiving portion, an engagement plate portion and a face material support plate portion, a first engagement portion on one edge of the engagement plate portion, and the other of the engagement plate portions A second engaging portion at an edge of the frame-like member, and the second engaging portion is rotated by rotating the first engaging portion in contact with the first engaging receiving portion of the frame-shaped member. A fitting including a pressing member for holding a face material between the frame-like member and the frame-like member via the face material support plate by contacting the second engagement receiving portion. if the receiving part, the direction found from a position securing the partition surface extending along the expected direction of the frame-like member between the opening edge of the accommodating portion in which the heat insulating material is arranged A first base piece that protrudes inward along the inner periphery, and a first inclined piece that inclines in a direction of gradually separating from the second engagement receiving portion as it protrudes from the protruding end portion of the first base piece toward the inner peripheral side. And a first tip piece extending inward from the protruding end of the first inclined piece along the direction of finding, and a proximity of the second engagement receiving portion from the protruding end of the first tip piece. And a first engagement receiving piece which is bent in the direction and abuts the first engagement portion of the pressing member .

According to this invention, since the partition surface extending along the prospective direction of the frame-like member is secured between the opening edge of the housing portion and the first engagement receiving portion is provided, the injection type heat insulation Even when the material is applied, there is no risk of incurring a leakage to the outside of the housing portion. Moreover, the first engagement receiving portion has a first inclined piece and a first tip piece between the first base piece and the first engagement receiving piece with which the first engaging portion of the pressing member abuts. Therefore , a distance can be secured between the first engagement receiving piece and the second engagement receiving portion .

Further, according to the present invention, in the joinery described above, the second engagement receiving portion protrudes toward the inner peripheral side along the finding direction from a position in which an interval in the prospective direction is secured with respect to the first engagement receiving portion. A second base piece; and a second engagement receiving piece bent in a direction approaching the first engagement receiving portion from the protruding end portion of the second base piece, and the partition surface in the frame-shaped member The distance from the prospective surface which becomes the same plane is configured such that the first engagement receiving piece and the second engagement receiving piece are the same.

  According to this invention, it is possible to further suppress the inclination angle of the pressing member that is required when the first engagement portion is attached and detached between the prospective surface of the frame-shaped member and the first engagement receiving portion.

Further, according to the present invention, in the joinery described above, the face material support plate portion is the same as the partition surface in the frame-shaped member in a state where the pressing edge member is attached to the frame-shaped member via the engagement plate portion. After extending in a direction away from the prospective surface that is a flat surface, it is bent toward the direction approaching the face material, and the front end supports the face material at a position beyond the heat insulating material of the frame-shaped member. When the mounting surface is attached to the frame-shaped member with the prospective surface facing upward, the engagement plate portion abuts the prospective surface of the frame-shaped member through the tip portion, and is from the center of gravity. The barycentric position is set so that the perpendicular passes through the base end side of the engagement plate part from the contact position with the prospective surface of the frame-shaped member.

  According to this invention, when it attaches with respect to the frame-shaped member in which the prospective surface faced upwards, a pressing edge member can be made self-supporting.

According to the present invention, since the provided first engagement receiving portion to secure the partition surface that extends I along prospective direction of the frame member between the opening edge of the accommodating portion, the injection-type Even in the case of applying a heat insulating material, there is no possibility of incurring a situation of leakage to the outside of the housing portion. Moreover, the first engagement receiving portion has a first inclined piece and a first tip piece between the first base piece and the first engagement receiving piece with which the first engaging portion of the pressing member abuts. and for that, it is possible to prevent the mutual distance between the first engagement receiving piece and the second engagement receiving portion is greatly shortened. Thereby, the inclination angle required when attaching and detaching the ledge member to the frame-like member can be kept small, and there is no possibility of causing interference between the face material support plate portion of the ledge member and the face material, The operation can be easily performed.
