Description

  The present invention relates to a screwing structure for an assembly window frame, and particularly a screwing window frame structure with high tightness.

A general window frame includes an upper frame, a lower frame, a left frame, a right frame, and a middle frame, and these fixing methods fasten and fix the window frames with screws.
Japanese Patent No. 3479650

    The problem to be solved is that the conventional window frame structure fixing method has low tightness and the degree of tightening varies depending on the operator. For this reason, the fixing method using only screws is not good in tightness.

  The present invention includes an I-shaped frame, a right I-shaped frame, an upper U-shaped fitting frame, a lower U-shaped fitting frame, a fixed structure, and a middle frame. The middle frame, the left I-shaped frame, and the right I-shaped frame are fixed with a fixed structure. The upper and lower U-shaped fitting frames have the same structure, and are fitted with a U-shaped joining plate and an M-shaped fitting plate. The most important feature is that the four corners of the window frame are fixed with a fixed structure on both sides.

    The screwing structure of the assembly window frame of the present invention has an advantage that it has high tightness and is practical.

As shown in FIG. 1, the present invention comprises a left I-shaped frame 1, a right I-shaped frame 1 ', an upper U-shaped fitting frame 2', a lower U-shaped fitting frame 2, a T-shaped fixing piece 4, It is composed of a pointed screw 5 and a middle frame 3. Among them, the left I-shaped frame 1 and the right I-shaped frame 1 ′ have the same structure, the entire cross-sectional shape is I-shaped, and U-shaped engagement grooves 11 and 11 ′ are formed on both sides thereof. A T-shaped fixing piece 4 is arranged there. Further, the structure of the inner frame 3 is divided into inclined reinforcing plates 31, 31 'and U-shaped engaging grooves 32, 33 on both sides, and a hollow engaging groove 34 is formed in the center of the cross section, as shown in FIG. The T-shaped fixing piece 4 is inserted there. Further, as shown in FIGS. 2, 3, 4, 5, 6, and 7, the left I-shaped frame 1 or the right I-shaped frame 1 ′ and the middle frame 3 are combined with each other. The T-shaped head 42 of the T-shaped fixed piece 4 is first put in the U-shaped engagement groove 11 of the left I-shaped frame 1, and the other end of the T-shaped fixed piece 4 is hollowly engaged with the middle frame 3. Place in groove 34.
The pointed screw 5 passes through the engaging groove wall of the middle frame 3 and the pointed tip is inserted into the fixing hole 41 of the middle frame, and the screw is fastened and propelled to make the pointed tip into the conical inclined surface of the fixing hole. As shown in FIGS. 5 and 6, the T-shaped fixing piece 4 slides as the tip of the screw advances, and the left and right I-characters pass through the left and right T-shaped fixing pieces 4. Pull the formwork 1 or 1 'toward the center.
2, 4 and 9, the middle frame 3 and the left I-shaped frame 1 or the right I-shaped frame 1 ′ are firmly fastened and fixed to each other.
Similarly, as shown in FIGS. 3, 5, 7, and 9, the T-shaped head 42 at one end of the T-shaped fixing piece 4 is inserted into the U-shaped engagement groove of the left or right I-shaped frame 1, 1 ′. 11, and the other end of the T-shaped fixing piece 4 is inserted into the engaging grooves 24 on both sides of the upper U-shaped fitting frame 2 ′ and the lower U-shaped frame 2, and the pointed screw 5 is Two pieces of T are formed by passing through the U-shaped fitting frame 2 ′ and the lower U-shaped frame 2 into the fixing hole 41 formed with the conical slope of the T-shaped fixing piece 4 and fastening in the same manner as described above. The left or right I-shaped frame 1, 1 ′ is slid and tightened toward the center by the sliding action of the character-shaped fixing piece 4, and is fixed to the upper U-shaped fitting frame 2 ′ and the lower U-shaped frame 2. The four corners of the window frame are fixed.

As shown in FIGS. 1 and 9, the upper U-shaped frame 2 ′ and the lower U-shaped frame 2 have the same fastening structure, including the U-shaped joining plates 22, 2 ′ 2 and the M-shaped fitting plate 21. The sandwiching plate 6 constituting the wall surface is fitted and supported by the two members 2′1. Among them, an arc-shaped reinforcing plate 211 is formed below the U-shaped engaging groove 23 above the M-shaped fitting plate 21 of the lower U-shaped fitting frame 2 and reinforcing plates 212 are provided on both sides thereof. The engaging groove 24 is formed in the center. Separately, a hook lump 221 is provided at appropriate positions on both side bases of the U-shaped receiving plate 22 so that the lower portions of the lower U-shaped fitting frame 2 are fitted.
The same applies to the upper U-shaped fitting frame disposed above the same.

As shown in FIGS. 8 and 9, upper and lower U-shaped engagement grooves 32 and 33 are arranged in the middle frame 3, and the base portions of the triangular holding legs 7 and 7 ′ are fitted and fixed in the engagement grooves. The sandwiching plate 6 is sandwiched and supported (see FIG. 9).
The left I-shaped frame 1 or the right I-shaped frame 1 ′ is provided with a U-shaped engagement groove 11, and the base portion of the rectangular holding leg 8 is hooked and fixed to the engaging groove and is held between the rectangular holding legs 8. The plate 6 is sandwiched and supported. The support structure of these clamping plates is common to the lower U-shaped frame 2 and the upper U-shaped frame.

It is a three-dimensional exploded view of the present invention. It is sectional drawing which couple | bonded the inner frame and I-shaped frame of this invention. It is sectional drawing which fixed the lower U-shaped fitting frame and the I-shaped frame on this invention. It is sectional drawing before couple | bonding the middle frame and I-shaped frame of this invention. It is sectional drawing before fixing a lower U-shaped fitting frame and an I-shaped frame on this invention. It is sectional drawing after combining the middle frame and I-shaped frame of this invention. It is sectional drawing after fixing a lower fitting frame and an I-shaped frame on this invention. It is sectional drawing which couple | bonded the clamping board, square clamping leg, and I-shaped frame of this invention. It is sectional drawing which couple | bonded the inner frame of this invention, the up-and-down U-shaped frame, the clamping board, and the triangular clamping leg.
