Description

seam tape

The present invention relates to an adhesive strip, in particular to a seam covering adhesive strip suitable for screen windows.

As shown in FIGS. 1 , 2 and 3 , it is a conventional rubber strip 1 that can be installed on a screen window module 2 . The rubber strip 1 has a T-shaped cross-section and includes a horizontal plate portion 101 and a vertical plate portion 101 . The sheet part 102, the screen window module 2 is arranged on a window frame 3 fixed on the wall, the screen window module 2 includes an upper frame bar 201, a lower frame bar 202, and a left and right movable set on the upper frame The movable frame 203 between the frame strip 201 and the lower frame strip 202, the rubber strip 1 is installed on the movable frame 203, so, when the user installs an inner window on the window frame 3 and has a vertical edge 401 4. When opened, the movable frame 203 can be pulled horizontally to be aligned with the vertical edge 401, so as to unfold a gauze (not shown), and the vertical piece 102 of the rubber The vertical edge 401 is used to prevent mosquitoes from entering the room through the gap between the vertical edge 401 and the movable frame 203 .

However, as shown in FIG. 2 , since the commercially available rubber strip 1 is the most simplified design, once the gap between the vertical edge 401 and the movable frame 203 is large, the rubber strip 1 The vertical sheet portion 102 of the vertical sheet portion 102 is often unable to reach the vertical side strip 401, and a gap 5 that allows mosquitoes to invade is usually formed between the front edge of the vertical sheet portion 102 and the inner side of the vertical side rail 401. Furthermore, Even if the vertical piece 102 of the rubber strip 1 can abut against the vertical side strip 401 , the vertical piece 102 has a thin cross-section, so the bearing effect is not good. In addition, since the rubber strip 1 is installed on the movable frame 203 When it is installed, the top and bottom ends of the rubber strip 1 are usually flush with the design of the installation groove provided by the movable frame 203. The strip 1 cannot effectively block a first drop gap 6 formed between the upper frame strip 201 and the window frame 3, and the rubber strip 1 cannot effectively block two formed on the movable frame 203 and the upper frame strip 201. the second drop gap 7 between the movable frame 203 and the lower frame bar 202, so that mosquitoes may enter the room through the first drop gap 6 or the second drop gap 7, even if someone tries to respond to the surrounding environment The top and bottom ends of the rubber strip 1 are cut out by changing the space. Since the section of the rubber strip 1 is thin, the support force of the rubber strip 1 after cutting is not good, and the shielding effect is also poor.

In addition, as shown in FIG. 3 , in actual use, since the vertical sheet portion 102 of the rubber strip 1 is a long sheet-like structure, its structural strength is not good, so the vertical sheet portion 102 often produces wavy shapes. deformation, which affects the abutment and tightness of the vertical side strip 401, and cannot effectively prevent mosquitoes from invading the room.

Accordingly, it is an object of the present invention to provide a seam mask that overcomes at least one of the disadvantages of the prior art.

Therefore, the seam masking strip of the present invention includes a first substrate, a first neck strip, a second substrate, a second neck strip, and an open loop strip.

The top and bottom ends of the sealing strip 100 of the present invention are flush when they leave the factory. Before installing the sealing strip 100 on the movable frame 240, the user can view the surrounding environment space changes to the mask. The top and bottom ends of the seam tape 100 are cut.

For example, as shown in FIGS. 8 and 5 , when the top cutting operation is to be performed, the user can cut a first predetermined length with a knife against the rear side of the second substrate 30, so that the The part of the first neck strip 20 is separated from the second substrate 30, and then the part of the first substrate 10 corresponding to the first predetermined length and the part of the first neck strip 20 are transversely cut, so that the The top end 21 of the first neck strip is flush with the top end 11 of the first substrate in the up-down direction. Then, the user can cut a second predetermined length downward with a cutter against the front side of the second substrate 30. The part of the second substrate 30 is separated from the second neck strip 40, and then the part of the second substrate 30 corresponding to the second predetermined length is cut laterally, so that the top end 31 of the second substrate is The up-down direction is higher than the first neck strip top 21 and the first substrate top 11, and the flush second neck strip top 41 and the ring strip top 54 are higher than the second neck strip top 54 in the up-down direction Substrate tip 31 .

As shown in FIGS. 8 and 6 , when the bottom end cutting operation is to be performed, the user can first cut a third predetermined length with a cutter against the rear side of the second substrate 30 , so that the first The part of the neck strip 20 is separated from the second substrate 30, and then the part of the first substrate 10 corresponding to the third predetermined length and the part of the first neck strip 20 are transversely cut, so that the first The bottom end 22 of the neck strip is flush with the bottom end 12 of the first substrate in the up-down direction, and then, the user can first cut a fourth upper part with a knife against the rear side of the sheet part 51 of the open loop strip 50 A predetermined length, the second neck strip 40 is separated from the sheet portion 51 of the open loop strip 50, and then the portion of the second substrate 30 corresponding to the fourth predetermined length is separated from the portion of the second neck strip 40 Cut transversely, so that the flush bottom end 32 of the second substrate and the bottom end 42 of the second neck strip are lower than the bottom end 22 of the first neck strip and the bottom end 12 of the first substrate in the up-down direction, And the bottom end 55 of the ring strip is lower than the bottom end 42 of the second neck strip and the bottom end 32 of the second substrate in the up-down direction.

After that, as shown in FIG. 10 , when the masking strip 100 is installed on the movable frame 240 , the first substrate 10 will be located in the installation groove 241 of the movable frame 240 , and the first neck strip 20 will face toward the movable frame 240 . Passing through the front side opening of the installation slot 241, the second substrate 30 will abut against the front side of the movable frame 240. Furthermore, as shown in Figures 11, 12, and 13, the upper frame bar 210 and the window Between the frames 300, a first drop gap 500 is formed due to the assembly relationship, and the part of the second neck strip 40 (see FIG. 5) higher than the top end 31 of the second substrate (see FIG. 5) can block the first drop gap 500. A drop gap 500 is formed between the movable frame 240 and the upper frame bar 210 and between the movable frame 240 and the lower frame bar 220 due to the assembly relationship. Two second drop gaps 600 are formed. The second substrate The part of 30 (see FIG. 5 ) higher than the top end 21 of the first neck strip (see FIG. 5 ) can block one of the second drop gaps 600 above, and the second substrate 30 (see FIG. 6 ) is lower than the first drop gap 600 . A portion of the bottom end 22 of a neck strip (see FIG. 6 ) can block another second drop gap 600 below, so as to reduce the probability of mosquitoes entering the room through the first drop gap 500 or the second drop gaps 600 . 14, when the elastic hook portion 52 of the open ring strip 50 abuts against the rear side of the vertical side strip 410 of the inner window 400, since the elastic hook portion 52 will be forced to elastically deform backwards, Therefore, the elastic restoring force of the elastic hook portion 52 will make the elastic hook portion 52 abut against the rear side of the vertical side bar 410 of the inner window 400 to prevent mosquitoes from getting between the vertical side bar 410 and the movable frame 240 . into the room.

Through the above description, the advantages of the present invention can be summarized as follows:
