Description

  The present invention relates to a frame provided with a cover member that is attached to a frame in a state of being attached to a mounting portion of a frame material, and a fitting including the frame.

  BACKGROUND ART A frame body including a frame material and a cover member is widely used as a frame body of a fitting. The frame material is installed in the opening of the building and is arranged outside the frame. The cover member is attached to the attachment portion of the frame member and covers a portion between the frame and the frame member and a portion of the frame outside the room. Further, as a frame of a fitting, a sash frame member that attaches a resin frame member to a metal frame member by engaging a resin frame member (cover member) and a metal frame member on the outside of the frame has been conventionally known. (See Patent Document 1).

  However, in the conventional sash frame material described in Patent Document 1, the engagement ridge and the insertion groove of the resin frame material engage with the engagement groove and the insertion ridge of the metal frame material, respectively. Therefore, it may be difficult to engage the resin frame member with the metal frame member, and the resin frame member may not be easily attached to the metal frame member. Further, since the resin frame material and the metal frame material are engaged at two places, it is difficult to release the engagement between the resin frame material and the metal frame material, and when the resin frame material is replaced, the metal frame material is removed from the resin frame material. May not be easily removed. For example, by cutting a part of the resin frame material over the entire length of the resin frame material, the engagement between the resin frame material and the metal frame material is released. Therefore, it takes time to replace the resin frame material.

It is possible to reduce the friction generated in the. Further, the space 64 formed between the mounting piece 31 and the second projecting piece 52 can further reduce the friction generated between the second projecting piece 52 and the mounting piece 31. Accordingly, the mounting piece 31 of the cover member 30 can be slid smoothly in the engagement recess 60.

  According to the present invention, the second pressing portion 39 arranged on the inner peripheral side of the engagement recess 60 can surely press the second projecting piece 52 to the outdoor side and elastically deform it. Further, according to the present invention, the engagement projection 37 of the mounting piece 31 projects toward the second projecting piece 52, and when the cover member 30 is removed, the engaging projection 37 and the first pressing portion 38 move toward the first projecting piece 51 side. Displace. As a result, the engagement protrusion 37 is easily disengaged from the engagement portion 55 of the second protrusion 52, and the engagement between the engagement protrusion 37 and the engagement portion 55 can be smoothly released.

  According to the present invention, the void 63 formed between the first projecting piece 51 and the outdoor side surface 42 of the frame 40 allows the first projecting piece 51 to be easily elastically deformed toward the indoor side. Further, according to the present invention, by forming the space 61 between the first projecting piece 51 and the mounting piece 31, it is possible to reduce the friction generated between the first projecting piece 51 and the mounting piece 31. . Since the engagement protrusion 37 is easily displaced toward the first protrusion 51 side by the void 61, the engagement protrusion 37 and the engagement portion 55 can be smoothly engaged and disengaged.

FIG. 7 is a cross-sectional view of the cover member 10 of the upper frame 5 and the mounting portion 5D of the frame member 5A, and shows a part of FIG. 2 in an enlarged manner. Further, FIG. 7 shows the cover member 10, the mounting portion 5D and the like similarly to FIG.
As illustrated, the cover member 10 of the upper frame 5 is configured similarly to the cover member 30 of the vertical frame 7, and has a mounting piece 11 and a cover portion 12. The mounting portion 5D of the frame member 5A has the same structure as the mounting portion 7D of the frame member 7A, and has a first projecting piece 71, a second projecting piece 72, and an engaging recess 80.

  The attachment piece 11 of the cover member 10 is similar to the attachment piece 31 of the cover member 30 in that the shielding portion 13, the step portion 14, the two groove portions 15 and 16 (the first groove portion 15 and the second groove portion 16), and the engagement protrusion 17 are provided. , A first pressing portion 18 and a second pressing portion 19. The first projecting piece 71 has a restricting projection 74, like the first projecting piece 51, and the second projecting piece 72 has an engaging portion 75 and a housing portion 77, like the second projecting piece 52.
