Description

  The present invention relates to a bracket structure for attaching a surface lattice together with an intermediate member to a window frame.

  Screw screws have been used to attach face grids to window frames fitted in building openings, but when aluminum screws are used for window frames and face grids, screw screws are used for mounting. There was a concern about the durability of the parts, and countermeasures were required.

  Under such circumstances, the present applicant has proposed Patent Document 1 and Patent Document 2.

Patent No. 3095783 (Claims and drawings) Japanese Patent Application No. 2001-135794 (Claims and Drawings)

  Briefly explaining the above proposal, as shown in FIG. 5, a through-hole is formed in the folded portion U of the bracket 5 for supporting the surface lattice 30 in the ear portion 3 extending from the both side portions 2 of the window frame. The portion U is fitted on the ear 3 and the upper and lower jaws T2 and T1 of the crimping tool T provided with the punch P and the punch hole H are contacted. The punch P is driven toward the punch hole H and the ear of the bracket 5 and the window frame. 3 and “caulking”.

  With the above proposal, the bracket mounting work has been simplified, and the durability of the mounting part has been dramatically improved. However, from customers, insect frames, etc. between the window frame and the face lattice. In addition, there was a demand to install the insect nets and the face grid without increasing the number of man-hours.

  In order to solve the above-mentioned problems, the present invention provides a structure in which the surface lattice 30 together with the intermediate member 21 is attached to the ear portion 13 of the window frame 10 attached to the opening of the building via the bracket 40. A hook formed integrally with the end of the latching claw support arm 47 extending from the body portion 45 of the bracket 40 in a gap formed between the edge of the intermediate member 21 fitted to the ear 13 and the ear 13 of the window frame 10. The retaining claw 42 is inserted, and the bracket 40 is fixed together with the intermediate member 21 to the ear portion 13 of the window frame 10 with the back contact plate 43 and the side contact plate 44 extending from the main body portion 45 of the bracket 40. A surface lattice 30 is attached, and the bracket material is higher in strength and hardness than aluminum and does not cause electrolytic corrosion.

  In order to achieve the above configuration, the entire bracket 40 is turned into a gap between the edge of the intermediate member 21 fitted to the ear portion 13 of the window frame 10 and the ear portion 13 of the window frame 10, and the latching claw is turned. 42 and the latching pawl support piece 41 are inserted obliquely, and the bracket 40 is turned in the opposite direction from that state to position the latching pawl 42 at a right angle to the gap, and the latching pawl 42 is placed in the gap And a method in which the back contact plate 43 and the side contact plate 44 are brought into contact with the intermediate member.

  According to the present invention configured as described above, the intermediate member for attaching the frame of the insect screen when attaching the bracket to the ear portion of the window frame can be attached without increasing the man-hours, and the attachment state is solid and durable. Is also good.

  In addition, by adopting a specific bracket material, the mounting is solid and reliable, and there is no worry about electric corrosion, and durability is also good.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 to 3, a fixed piece A3 is welded A2 to a reinforcing bar A1 of a building opening to fix an anchor A, and a window frame 10 is attached to a mounting portion A4 of the anchor A. Sealing S is applied to the gap.

  An intermediate member 21 that supports the insect screen sash 20 is fitted to the ear portion 13 of the window frame 10, and a gap formed between the ear portion 13 and the intermediate member 21 at the end of the hooking claw arm 47 of the bracket 40. A hooking pawl 42 is fitted together with the hooking pawl support 41, and a surface grid mounting portion 46 for attaching the cross rail 31 of the surface grid 30 is formed at the end of the body portion 45 of the bracket 40 integral with the hooking pawl arm 47. Yes.

  The intermediate member 21 forms an arithmetical number “9” having an angular cross section (not limited to this shape). The end of the hook portion 22 is a ridge, and the window frame of the portion facing this The ten ears 13 are recessed to form a fitting groove 23, and an insect screen sash 20 is attached to the hollow part 24 by a screw 25. Reference numeral 27 denotes an insect net, and 26 denotes a bushing for attaching the insect net.

  Next, a procedure for attaching the bracket 40 to the ear portion 13 of the window frame 10 via the intermediate member 21 will be described in detail with reference to FIGS. 1 and 4. The hook portion 22 of the intermediate member 21 is fitted to the ear portion 13 of the window frame 10, and the end edge of the hook portion 22 forms a fitting groove portion 23 so that the fitting state does not go out of the way, and the gap of the fitting portion is set. The hooking claw support piece 41 and the hooking claw 42 of the bracket 40 are fitted and stuck together, and the window frame 10, the intermediate member 21, and the bracket 40 are fixed to each other.

  In order to insert the hooking claws 42 together with the hooking claw support portions 41 into the gaps between the ear portions 13 of the window frame 10 and the hook portions 22 of the intermediate member 21, the brackets are first attached to the ear portions 13 of the window frame 10. 4, the bracket 40 is turned upward by about 45 degrees as shown in FIG. 4, and the claw 42 is hooked in the gap between the ear portion 13 and the intermediate member 21, and the tip thereof is the above-mentioned ruled line. The bracket 40 is turned in the direction of the arrow with the contact point between the tip of the hooking claw 42 and the ear portion 13 as a fulcrum.

  By doing so, the hooking claws 42 are strongly fitted in the gap between the ear portion 13 of the window frame 10 and the intermediate member 21 by the action of the lever of the bracket 40, and the bracket 40 is inserted into the ear portion of the window frame 10. When positioned at a right angle to 13, the back plate 43 and the side plate 44 come into contact with the intermediate member 21 to stabilize the mounting state.

  Here, since the material of the bracket 40 supports the insect net sash and the surface lattice in this embodiment, it is necessary to adopt a material having a considerable strength and hardness, and the bracket 40 and the aluminum are used. It must not cause electrical corrosion between them. From that viewpoint, stainless steel (SUS-308) is adopted.

  Further, in FIG. 1A, the tip of the hooking nail 42 bites into the surface of the ear portion 13 of the window frame 10, and an enlarged cross section taken along the line AA of this portion is shown in FIG. ). That is, if the notch 13n is provided in the ear 13 of the window frame 10 in advance, the tip 42t of the hook 42 is brought into contact with the notch 13n, and the hook 42 is rotated in the direction of the arrow together with the bracket 40, the positioning and attachment are ensured.・ It becomes solid.

  Here, the fastening allowance of the hooking claw 42 that fits in the gap between the ear portion 13 of the window frame 10 and the intermediate member 21 is set to +0.2 mm, but this fastening allowance is experimentally determined by the size and material of each part. The Further, the strength between the hanging claw arm 47 and the hanging claw 42 needs to have a dimensional configuration and strength so as not to buckle while the bracket mounting operation is performed.

  As described above, according to the present invention, it is possible to easily attach the surface lattice by interposing the intermediate member in the window frame, and the durability of the attaching portion is also good.
