  The extension member 29 attached to the vertical rod 22 is composed of one part, and has a fixed surface portion 29c fixed in contact with the bottom wall 24a, and two opposing surface portions 29d rising from the fixed surface portion 29c in the vertical direction. The two opposing surface portions 29d are connected by a connecting portion 29e.

  In the present embodiment, a communication hole 28 is provided in the bottom wall 24a for the summoning bar 22b of the vertical bars 22. The extension member 29 attached to the summoning bar 22b is formed with an extension member communication hole 29f that communicates with the communication hole 28 in the connection portion 29e. In addition, although the communication hole 28 is not provided in the frame side vertical rod 22a, since the extending member 29 also has a function of supporting the glass body 5, the frame side vertical rod 22a also has the same extending member 29 as the summoning rod 22b. Is installed.

  With such an extension member 29, in the upper collar 20, the lower collar 21, and the summoning collar 22b, a space having substantially the same cross-sectional shape as the communication hole 28 is formed continuously to the communication hole 28, and this slit-shaped space The communication hole 28 extends from the hollow portion 23 toward the gap region 5c.

  An airtight material 26 is provided between the indoor wall 24b constituting the opening groove 24 and the indoor surface of the first glass 5a, and between the outdoor wall 24c constituting the opening groove 24 and the outdoor surface of the second glass 5b. Also, an airtight material 26 is provided. Moreover, the airtight material 26 is also provided between the facing surface portion 29d of the extending member 29 and the outdoor surface of the first glass 5a and between the facing surface portion 29d of the extending member 29 and the indoor surface of the second glass 5b, respectively. Thus, the outer peripheral portion of the glass body 5 is sandwiched and fixed in the opening groove 24 of the housing 23 while the extension member 29 is sandwiched between the first glass 5a and the second glass 5b.

  Each of the first glass 5a and the second glass 5b constituting the glass body 5 is provided with a setting block 27 between the outer peripheral surface and the bottom wall 24a of the opening groove 24 of the lower collar 21, and this setting block 27 By being placed on top, it is arranged at a predetermined position in the housing 4.

  As described above, the hollow portion 23 of the housing 4 and the gap region 5 c are communicated by the communication hole 28 and the extension member 29. As a result, the air in and near the communication hole 28 vibrates strongly at a specific frequency, and the acoustic energy is converted into heat energy by friction between the inner wall surface of the communication hole 28 and the air, and consumed as frictional heat. Therefore, a sound absorbing action is generated and noise is absorbed. At this time, the width of the communication hole 28, the dimension of the extending member 29, and the volume of the hollow portion 23 may be set so that the resonance frequency becomes a desired value.

  Since the resonance frequency varies depending on the width of the communication hole 28, for example, a sash specialized for sound insulation in a specific frequency range can be used. In addition, by providing diversity in the width of the communication hole 28 on each side of the housing 4, a sash having excellent sound insulation performance over a wide frequency range can be obtained. In this way, it is possible to obtain a sash rich in variations by changing the width and installation form of the communication hole 28.

  The resonance frequency also varies depending on the length in the extending direction of the communication hole 28 by the extending member 29 (hereinafter referred to as the neck length). The longer the neck length, the lower the resonance frequency, and the shorter the neck length, the higher the resonance frequency. Thus, since the resonance frequency can be changed by adjusting the neck length, it is possible to obtain a sash according to the application.

The correlation equation between the structure of the housing 4 and the resonance frequency (f ₀ ) is shown below. Since the resonator according to the present invention has a structure to which a Helmholtz resonator is applied, the resonance frequency (f ₀ ) of the resonator is variable depending on the structure of the sash. The resonance frequency (f ₀ ) is calculated by the following factors using the following correlation formula, and high sound absorption performance is obtained in the vicinity of the resonance frequency (f ₀ ) calculated from the correlation formula.

b: width of the communication hole B: width of the air layer in the hollow portion (length in the left-right direction)
L: Thickness of the air layer in the hollow portion (length in the vertical direction)
A: Cross-sectional area of hollow part (= B × L)
t: neck length p: aperture ratio (b / B)
t ': opening end correction C: sound velocity f ₀ in the air: the resonance frequency

The opening end correction t ′ is a parameter for correcting the neck length. As described above, air in the slit space vibrates, but actually air slightly above the upper end and slightly below the lower end also vibrates, contributing to sound absorption. Therefore, when calculating the resonance frequency, it is necessary to correct this portion, so the neck length t is corrected by the opening end correction t ′.

  Each hollow portion 23 of the upper bowl 20 and the summoning bowl 22b is provided with a sound absorbing material 23a in the vicinity of the communication hole 28 so as to straddle the opening of the communication hole 28. Since the sound absorbing material 23a promotes the conversion from the acoustic energy of the vibrating air to thermal energy, the sound insulation performance of the window sash can be further improved. The type of the sound absorbing material 23a is not particularly limited, but fiber materials such as glass wool and rock wool are preferable. Further, an aluminum sound absorbing material such as aluminum fiber, aluminum cutting waste, and aluminum sintered body is preferable. The aluminum sound-absorbing material does not absorb moisture and thus hardly deteriorates and is excellent in recyclability.

  Thus, the hollow portion 23 of the housing 4 is used as a component of the resonator, the extension member 29 is fixed to the bottom wall 24a of the opening groove 24, and the communication hole 28 is formed in the first glass 5a and the second glass 5b. Since the glass body 5 is held by the extension member 29, the resonator can be easily configured while considering the design without exposing the constituent elements of the resonator. The sash can be provided with a sound insulation property with a simple structure and has a high design property.
