Abstract

This invention provides a simple inner window panel holder that can be easily attached to existing or newly installed curtain rails, and since it sags minimally and opens and closes smoothly, it can be installed in existing houses without double-glazed windows to provide good insulation at a low cost. [Solution] This is a simple panel holder for an inner window, having a holder 1 with a structure that holds a panel 8 at the bottom, and a pin 2 or hook 4 at the top for attachment to a curtain rail runner 5. An inner window using this invention has the advantage of preventing sagging due to its own weight by being suspended from a curtain rail runner attached to a curtain rail via a hook or pin. It also has the advantages of being able to open and close more smoothly than a roller-type inner window of the same area and weight, and being easy to install.

Description

Technical Field

[0001] This invention relates to a holder for easily creating an inner window mainly for heat insulation purposes, which is installed on windows such as those in residences.

Background Art

[0002] Currently, as a simple inner window using a panel such as hollow polycarbonate, products are on the market where a shoji screen with the four sides of the panel covered by a frame is installed between rails arranged vertically on the window frame.

[0003] However, for these products, especially when installed on windows with a certain height, a highly rigid frame or reinforcement is required to prevent the panel from sagging due to its own weight. Also, there are drawbacks such as a certain force being required for opening and closing, a large number of parts, and installation being time-consuming.

Summary of the Invention

Means for Solving the Problems

[0004] In this invention, a hook or pin for passing through the hole of a curtain rail runner is provided on the holder for suspending the panel constituting the inner window.

Effects of the Invention

[0005] The inner window using this invention has the advantage of preventing sagging due to its own weight by being suspended from the curtain rail runner attached to the curtain rail via a hook or pin. Also, it has the combined advantages of being able to be opened and closed more smoothly than a shutter-type inner window with the same area and weight, and being easy to install.

Brief Description of the Drawings

[0006] [Figure 1] It is an explanatory drawing showing a state where a plurality of Example 1 of this invention with a panel 8 attached is hung from a curtain rail runner main body 5 via a pin 2. [Figure 2]This is an explanatory diagram showing a panel 8 attached to Embodiment 1 of the present invention, which is equipped with multiple pins 2, and suspended from the curtain rail runner body 5 via the pins 2. [Figure 3] In the cross-sectional view of Embodiment 1 explained in Figures 1 and 2, the present invention is represented by upward-sloping hatching. [Figure 4] This is a cross-sectional view of one of the embodiments of Embodiment 1 in which the pin 2 and holder 1 are integrated. [Figure 5] This is an explanatory diagram showing multiple embodiments of the present invention (Embodiment 2) with panels 8 attached, suspended from the curtain rail runner body 5 via hooks 4. [Figure 6] This is an explanatory diagram showing a panel 8 attached to Embodiment 2 of the present invention, which is equipped with multiple hooks 4, and suspended from the curtain rail runner body 5 via the hooks 4. [Figure 7] In the cross-sectional view of Embodiment 2 described in Figures 5 and 6, the present invention is represented by upward-sloping hatching. [Modes for carrying out the invention]

[0007] The goal of installing inner windows in existing window frames of houses that do not have double-glazed windows was achieved with a small number of parts. [Examples]

[0008] The structure of Embodiment 1 of the present invention will be explained with reference to the cross-sectional view in Figure 3. The holder 1 has a structure in which the panel 8 is sandwiched in the gap at its bottom, but the method of sandwiching and holding the panel 8 is arbitrary, such as holding the panel 8 by compressing it with a spring function directed inward at the bottom of the holder 1, holding it using adhesive or glue, or fixing the holder 1 and the panel 8 with screws.

[0009] A hole for passing a pin 2 through is provided at the top of the holder 1, and a retainer 3 is attached to the pin 2, which passes through this hole and the curtain rail runner hook hole 7.

[0010] The upper structure of Embodiment 2 of this invention will be explained with reference to the cross-sectional view in Figure 7. The hook 4 attached to the main body 1 can be easily attached to the curtain rail runner hook hole 7 by rotating left and right. In the figure, the holder 1 and the hook 7 are connected by a ball joint, but other connection methods such as a pin joint can also be selected, as long as they allow for flexibility in attaching the hook 5 to the curtain rail runner hook hole 7 when the holder 1 with the panel 8 attached is in an upright position. [Industrial applicability]

[0011] The simple interior window using this invention can be easily attached to existing curtain rails or newly installed curtain rails, and opens and closes smoothly with minimal sagging. Therefore, by installing it in existing houses that do not have double-glazed windows, it can provide good insulation at a low cost. [Explanation of Symbols]

Claims

[Claim 1] A holder having a structure that holds a panel at the bottom, wherein a pin or hook for attaching to a curtain rail runner is provided at the top.
