DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a sash protective material A according to an example of the present invention will be described with reference to FIGS.

[0007] The sash protective material A of this embodiment is suitable for the outer frame 1 of a pull-type sash. Protective material A for this sash
Is the outer frame 1 of the pull type sash as shown in FIG.
Are formed in an L-shape by a polyolefin-based bead foam.

The polyolefin bead foam constituting the sash protective material A is a foam using beads of polyethylene, polypropylene, or a copolymer containing at least 50 parts by weight thereof, and has an expansion ratio of 5%. ~ 45
It is necessary that the compressive strength is 0.069 to 1.08 MPa. The polyolefin-based bead foam has a smoother surface and a higher stiffness as compared to conventionally used polystyrene foam. Therefore, even if they rub against each other, the outer frame 1 is hardly scratched and hardly broken,
Can withstand repeated use. The inventors of the present invention have conducted experiments and confirmed that they can withstand dozens of repeated uses. Further, the expansion ratio and the compressive strength are for obtaining an excellent buffering performance and preventing a stop band (not shown) to be described later from digging into.

As another example, the sash protective materials B and C described later are also formed of the same polyolefin-based bead foam as described above.

As shown in FIG. 2, two narrow insertion grooves 2 are formed on the inner corner surface of the L-shaped sash protective material A on the side addressed to the outer frame 1. They are formed in parallel. The insertion groove 2 is for inserting and holding a mounting flange portion 3 projecting to fix the outer frame 1 to a building on the outer periphery of the outer frame 1.

The position of the mounting flange 3 on the outer frame 1 is slightly different depending on the manufacturer or the like. Further, the outer frame 1 of the sliding sash has a large width for holding the two window frames in a sliding manner, and the width of the sash protective material A is inevitably wide. One insertion groove 2
When the protective material A for sash provided with the sash can be used for a plurality of types of outer frames 1 in which the positions of the mounting flanges 3 are different, the outer frame is It is necessary to make the width of the sash protective material A wider so that 1 does not protrude from the sash protective material A. However, if two (three or more) insertion grooves 2 are formed corresponding to the difference in the position of the mounting flange portion 3 as in this example, the sash protective material is formed. A without widening the width of A
The same sash protective material A can be used for a plurality of types of outer frames 1 having different positions.

As is apparent from FIGS. 2 to 4, the insertion groove 2 has a V-shaped cross section, and a flat circular arc-shaped projection 4 projects inward along the length of the groove 2 alternately. ing. The projecting portion 4 has a front surface (insertion groove 2).
Of the insertion groove 2 stands vertically in the insertion groove 2 having a V-shaped cross section, and extends from the upper end of the insertion groove 2 to a middle portion in the depth direction (preferably 1/2 to 2 of the depth of the insertion groove 2). /
Projecting over 3). If the insertion groove 2 having such a protrusion 4 is used, even if the thickness of the mounting flange 3 is slightly different due to a difference in a manufacturer or the like, the mounting flange 3 inserted by the elastic deformation of each protrusion 4. Can be reliably pinched from the left and right.

As shown in FIG. 1, on the outer corner surface (opposite to the inner corner surface) of the sash protective material A,
With the book sash protective material A addressed to the four corners of the outer frame 1, a stop band (not shown) is wrapped around the book sash protective material A at the four corners in the circumferential direction of the outer frame 1. When fixing the sash protective material A to the outer frame 1, two band grooves 5 are formed for accommodating the stop band and preventing its displacement. One band groove 6 is also formed in a direction perpendicular to the band groove 5. The band groove 6 accommodates the stop band when the stop band is wound in the front-rear direction of the outer frame from above and below the left and right sash protection members A in the state of FIG.

FIG. 5 is a perspective view showing a sash protection material B according to another example of the present invention. The sash protection material A is suitable for the outer frame 1 of the pull-type sash. However, it is particularly suitable for the outer frame (not shown) of the door type sash. Figure 1
In the same manner as described above, the outer frame 1 in FIG. 1 may be replaced with the outer frame of the door type sash, and the mounting flange 3 may be replaced with the mounting flange of the outer frame of the door type sash. Therefore, like the sash protection material A described above, the sash protection material B also has the insertion groove 2 from which the protrusion 4 protrudes.
And band grooves 5 and 6. However, since the mounting flange portion of the door type sash protrudes at a substantially constant position even if the manufacturer or the like is different, the insertion groove 2 in the sash protection material B is one.

FIG. 6 is a perspective view showing a sash protection material C according to still another embodiment of the present invention, which is particularly suitable for a window frame (not shown) of a sliding type or door type sash. It has become something. That is, the protective material C for sash has a receiving recess 7 for accommodating a corner portion of the window frame on an inner corner surface addressed to the window frame. The corners of the window frame are inserted into the receiving recesses 7, so that the corners of the window frame can be addressed in a stable state. Also, since the corner portion of the window frame is inserted into the receiving concave portion 7 so that the window frame does not deviate in the front-rear direction, the outer corner surface has
Only a band groove 5 for accommodating a stop band wound in the circumferential direction of the window frame is provided.

[0016]

As described above, the present invention is not only capable of obtaining a high buffering effect, but also capable of withstanding repeated use, and possibly causing scratches even when the sash is rubbed against each part of the sash to be protected. There is no one.
