Description

  The present invention relates to an opening device and a method for constructing the opening device.

  There are various performance requirements for opening devices such as windows and sashes. First, what is required is a so-called basic performance, which includes wind pressure resistance, water tightness, and air tightness. In addition to basic performance, enhancement of additional functions to enhance the comfort of living space is also required. Such additional functions include, for example, thermal insulation. Alternatively, heat and light shielding performance may be required.

  For example, a blind built-in sash may be provided in the opening device to provide heat or light shielding. A sash with a built-in blind is a sash that is specifically designed to have a blind.

  Further, Patent Document 1 proposes a double-glazed glass with a built-in blind. In the blind built-in type double-glazed glass, the blind is disposed in an intermediate air layer of the sealed double-glazed glass.

JP 2013-227802 A

  A dedicated sash such as a blind built-in sash has a higher manufacturing cost than a general-purpose sash.

  In addition, when the double-glazed glass with a built-in blind is directly exposed to the external environment such as outside air or solar radiation, the influence of the external environment continuously acts on the intermediate air layer. For this reason, the deterioration of quality due to the external environment tends to proceed more easily than general blinds used indoors. When it is necessary to replace the blind, it is customary to replace the double-glazed glass as a whole, but a difficult process may be included in the replacement work. For example, for double-glazed glass with a seal, it is particularly difficult to cut the seal on the outside of the higher floor of the building.

  The present invention has been made in view of such problems, and one of the exemplary purposes of an aspect thereof relates to the construction and maintenance of the opening device, and to improve the ease or safety of field work. is there.

  In order to solve the above problem, an aspect of the present invention relates to an opening device including an outer panel and an inner panel. The opening device includes an outer casing that houses the outer panel, and an inner casing that is detachably attached to the outer casing from the indoor side and that houses the inner panel. The inner casing is detachably supported on the inner peripheral surface of the outer casing on the indoor side.

  According to this aspect, the inner casing can be detached from the outer casing with respect to the outer casing. Since it is not necessary to remove the outer panel for attaching and detaching the inner casing, field work such as construction and maintenance of the opening device is facilitated. Since it is detachable on the indoor side, the safety of work particularly on the high floor of the building is improved.

  Here, the “outer casing” may be a casing of a shoji screen. In that case, the opening device is housed in the frame that is fixed to the building opening, the outer panel and the outer casing provided with the outer casing, and removable from the indoor side to the outer casing. It is equipped with the inner panel and the inner sword provided with the inner collar. Alternatively, the “outer fence” may be a frame fixed to the building opening. In that case, the said outer panel may be directly accommodated in the said outer casing, ie, a frame.

  A frame and an external panel are housed in the frame, and the frame of the internal frame is detachably supported on the inner peripheral surface of the outer frame of the outer frame or the inner peripheral surface of the frame. Therefore, the inner shoji can be attached to or removed from the indoor side with respect to the outer shoji or outer panel held in place by the frame. Since the inner shoji can be attached and detached from the indoor side without removing the outer shoji or the outer panel, field work such as construction and maintenance of the opening device is facilitated. Since it is detachable on the indoor side, the safety of work particularly on the high floor of the building is improved.

  The frame is fixed to the building opening, and the shoji or outer panel is placed in the frame. The outdoor part of such an opening device can also be regarded as one opening device constituted by a frame and a shoji or outer panel. As this outdoor portion, for example, an existing opening device can be adopted. An opening device with improved performance can be provided by additionally installing the indoor side part including the inner shoji. For example, a desired basic performance can be provided by the outdoor portion, and additional functions such as heat insulation and shielding performance can be provided by the indoor portion, thereby realizing a high-performance opening device as a whole. Further, by adding an indoor portion to the existing opening device, it is possible to improve the performance of the existing opening device or add a new function.

The outer panel may be sandwiched between an outdoor portion of the outer casing and an edge member attached to the indoor side. The inner collar may be detachably supported by the pressing edge member.
According to this aspect, the outdoor part of the opening device has a so-called edge structure. A pressing member is provided on the indoor side, whereby the outer panel is fixed. Therefore, not only the inner shoji but also the outer shoji or the outer panel can be built from the indoor side. Moreover, the support part for the casing of a shingles can be provided by a pushing edge member.

A latch receiving portion may be provided on the inner peripheral surface of the outer casing on the indoor side, and a latch may be provided on the outer peripheral portion of the inner casing. The inner casing may be attached to the outer casing by engaging the latch and the latch receiving portion, and may be removed from the outer casing by releasing the engagement.
According to this aspect, the inner frame of the inner casing or the inner inner surface of the frame is detachably supported by the latch mechanism. Therefore, it is possible to easily attach and detach the inner shoji to the outer shoji or the frame.

The outer panel may comprise single glass or double glazing. The inner panel may include double-glazed glass or double-glazed glass with a built-in blind.
According to this aspect, it is possible to select glasses having different performance, application, or design for each of the outer panel and the inner panel and combine them. Thus, various opening devices having various performances can be configured.
For example, an opening device having shielding performance can be provided by adopting a blind built-in type double-glazed glass as a panel for a naive child. The external environment acts on the outer shoji or outer panel, and thus the inner shoji is protected to some extent by the outer shoji or outer panel. Since the inner cot is not directly exposed to the external environment, the progress of deterioration of the blind over time can be suppressed.

  The other aspect with this invention is related with the construction method of an opening part apparatus. The method includes a step of fixing a frame body of the opening device to a building opening, and a step of placing a shroud of the opening device in the frame body from the indoor side or the outdoor side. The storing step includes a step of providing a support portion for the inner casing of the opening device on the inner peripheral surface on the indoor side of the outer casing.

  The construction method of the opening device may further include a step of detachably mounting the inner limb to the outer limb from the indoor side. The casing of the inner shoji may be detachably supported by the support portion.

  The other aspect with this invention is related with the construction method of an opening part apparatus. The method includes a step of fixing a frame body of the opening device to a building opening, a step of housing an outer panel of the opening device in the frame body from an indoor side or an outdoor side, and an indoor side of the frame body And a step of providing a support portion for the casing of the inner edge of the opening device on the peripheral surface.

  The construction method of the opening device may further include a step of detachably attaching the inner cot to the frame body from the indoor side. The casing of the inner shoji may be detachably supported by the support portion.

  The other aspect with this invention is related with the construction method of an opening part apparatus. The method includes the step of detachably mounting the inner impingement of the opening device from the indoor side to the outer impingement or frame of the opening device. The casing of the inner shingle is detachably supported on the inner peripheral surface of the inner casing of the outer casing or the inner peripheral surface of the frame.

  Another aspect of the present invention relates to a method for constructing an opening device for refurbishing an existing sash. The method includes a step of removing a shoji or panel from the existing sash, a step of housing the outer shoji or outer panel of the opening device in the frame of the existing sash from the indoor side or the outdoor side, Providing a support portion for the inner casing of the opening device on the indoor inner peripheral surface of the frame body or on the indoor inner peripheral surface of the frame body.
