Description

Filling piece for window

The present invention relates to a peeling piece for windows and doors, and more particularly, to a peeling piece for windows and doors that can be fitted between at least a pair of rails provided on opposite surfaces of a window frame to prevent thermal bridges and improve waterproofing, thermal insulation, and soundproofing properties. is about

In general, double sliding windows are installed in an opening such as a window or a doorway to block the inside of a building from the outside to perform a function of blocking and opening from the outside.

The sliding window has a structure in which the windows installed on the window frame are opened and closed by sliding left and right. These sliding windows are generally installed in the window frame frame, consisting of 2 or 4 pairs depending on the number of windows, but structurally, there is always a gap between the window frame and the window.

Accordingly, in order to prevent rain, wind, and pests from entering the gap space, a windbreak device, also called a wind plate or a filling piece, is generally used in the gap space between the window frame and the window sill.

With respect to such a peeling piece, a prior application has been made as "Peeling piece for windows", etc. in Republic of Korea Utility Model Publication No. 20-0401750 (published on November 14, 2005).

According to the Republic of Korea Utility Model Publication No. 20-0401750 "Peeling piece for windows", the peeling piece 3 provided with a plurality of split pieces 3a is coupled to the groove 1a formed on the inner circumferential surface of the window frame 1 . (see FIG. 1).

However, such a conventional technique has a problem of generating contamination and odor by leaving the condensed water flowing down after forming on the indoor side glass window in winter without discharging it to the outside through a discharge hole provided on one side of the window frame frame.

In addition, in the process where the continuous pressurization of the changjak is continued for a certain period of time, the elasticity of the split piece that is in contact with the changjak and performs an airtight function is weakened and deformation occurs, so that water flows as it is along with the wind between the deformed split pieces. There is a problem in that the interior material cannot be damaged and confidentiality cannot be maintained.

KR 20-0401750 Y1 (2005.11.21.)

The present invention has been devised to solve the above problems, and it can improve the airtight performance by easily blocking the gap space between the window frame frame and the window sill. An object of the present invention is to provide a peeling piece for windows and doors that can prevent it.

In order to realize the object as described above, the present invention provides a peeling piece for windows and doors for blocking a gap between overlapping portions of a window frame frame and a sliding window sill, comprising: a base member fixedly disposed on an inner circumferential surface of the window frame frame; a cushion member formed in a lump on the upper surface of the base member to block the gap space; and a cover member surrounding the upper surface of the cushion member, wherein the cushion member has a moisture absorption rate of 10% or less.

The peeling piece for windows and doors of the present invention according to the configuration as described above is shaped in a single lump to block the gap space between the window frame frame and the window sill, thereby improving airtightness performance.

In addition, the peeling piece for windows and doors of the present invention can exhibit a low moisture absorption rate because the value of the closed cell ratio of the cushion member is large.

In addition, the peeling piece for windows and doors of the present invention can smoothly discharge the condensed water accumulated in the space between the rails and the rails to one side of the window frame by including a condensed water discharge passage on the lower surface of the base member.

Referring to FIG. 2 , the peeling piece 100 for windows and doors according to a preferred embodiment of the present invention is between at least one pair of rails 21 provided on opposite surfaces of the window frame 20 , that is, the groove portion 22 . By being fitted to the changjjak 10, when the changjjak 10 is completely closed, the changjjak 10 and the changjjak 10 are positioned opposite to each other at the top and bottom of the overlapping portion. That is, in the case of sliding windows, the overlapping portions of the windows 10 are designed to engage with each other, so that a certain amount of soundproofing and thermal insulation effects can be obtained.

In this case, as the upper and lower portions of the overlapping windows 10 are spaced apart from the inward surface of the window frame 20, a gap space S is inevitably created therebetween. Accordingly, when the changjjak 10 is completely closed, the peeling piece 100 is inserted and installed on the upper and lower sides of the portion where the changjjak 10 overlaps.

3 and 4, preferably, the peeling piece 100 includes a base member 110 fixedly disposed in the groove portion 22 of the window frame 20, and one on the upper surface of the base member 110. It may include a cushion member 130 formed of a mass of to block the gap space (S) and a cover member 140 surrounding the cushion member 130 .

Here, the base member 110 has a rectangular shape having a predetermined height, and a seating groove portion (not shown) so that the cushion member 130 is seated by forming the upper surface of the base member 110 to be stepped. By providing , the sliding phenomenon caused by the frictional force applied to the cushion member 130 during sliding opening and closing of the window sill 10 is prevented in advance. In addition, on the bottom surface of the base member 110, which is in contact with the window frame 20, an intaglio condensed water (W) discharge flow path 111 is formed to discharge the condensed water (W) existing in the groove portion 22 to one side. plays a role in making

Referring to FIGS. 5 and 6 , when described in more detail, water droplets are formed on the indoor window sill 10 due to dew condensation caused by a temperature difference between indoors and outdoors in winter. These water droplets are collected in the lower groove portion 22 of the window frame 20, and the dew water (W) generated by collecting water droplets is discharged to the outside through a dew water discharge hole (not shown) provided on one side of the window frame 20. is emitted

In this case, the base member 110 inserted into the groove portion 22 prevents the flow of the dew condensation water (W). Accordingly, the discharge passage 111 is formed on the bottom surface of the base member 110 so that the dew condensation water (W) can pass without clogging. Here, the condensed water (W) discharge passage 111 may be formed to be curved. As a specific example, the condensate water (W) discharge passage 111 is preferably formed in a 'C' or 'S' shape. That is, when the cold outside air including the dew water (W) is introduced through the discharge path (W) formed in the 'C' or 'S' shape, it has a certain stagnation time, and accordingly, the outside air and the dew water (W) Inflow can be reduced. Of course, the present invention is not limited thereto, and any shape that allows the dew condensation water (W) to pass through without clogging is possible.

The base member 110 is, for example, polyolefin including polyethylene, polypropylene, and copolymers thereof, acrylonitrile butadiene stryene copolymers (ABS), polybutylene terephthalate, nylon, poly It may be made of at least one material selected from the group consisting of carbonate, polyvinyl chloride, and an alloy. As a specific example, the base member 110 may be at least one selected from the group consisting of polypropylene, ABS, and polyvinyl chloride, which are materials mainly used for injection.

And the fixing plate 120 is coupled to the upper surface of the base member 110 by a fastening member (reference numeral not shown). At this time, concave-convex portions 121 are formed on both sides of the fixing plate 120 , and the concave-convex portions 121 protrude at least one, preferably two, respectively in the horizontal direction on both sides of the base member 110 . there is. As the concave-convex portion 121 is pressed and closely adhered to the inner wall of the groove portion 22 when the base member 110 is forcibly fitted, the base member 110 can be firmly positioned.

The fixing plate 120 may be made of a metal material, for example, a corrosion-resistant stainless steel material. Of course, the present invention is not limited thereto, and any material having excellent strength and water resistance may be substituted, and it is of course also possible to use the fixing plate 120 in a removed state depending on the circumstances.

7 is a bottom view showing a state before and after installation of another embodiment of the peeling piece for windows and doors according to the present invention.

As shown in FIG. 7 , the base member 110 ′ is formed so that both central portions 112 , which are in contact with the inner wall of the groove portion 22 of the window frame 20 , protrude more roundly than the width of the groove portion 22 . and, on the inside thereof, an arch-shaped elastic elongated hole 113 is formed to face. That is, the base member 110 ′ is configured in a state in which the fixing plate 120 is removed to enable flexible installation and disassembly when fitting into the groove portion 22 , and also scratch the inner wall of the groove portion 22 . It has the effect of preventing damage to the back.

The elastic long hole 113 is formed in the shape of an arc-shaped long hole, and is positioned so that curved portions face each other in the width direction.

As the base member 110' is pressed and closely adhered to the inner wall of the groove portion 22 of the window frame 20, the elastic elongated hole 113 is contracted, so that the base member 110' is firmly positioned. be able to

Meanwhile, the cushion member 130 is attached to the upper surface of the base member 110 . In this case, the cushion member 130 may be attached through one or more selected from the group consisting of, for example, ultrasonic welding, high-frequency welding, and thermal compression. As a specific example, the cushion member 130 may be attached to the upper surface of the base member 110 through high-frequency fusion, which can be quickly attached and have excellent airtightness to the attached portion.

The cushion member 130 is installed along the sliding opening/closing direction of the window sill 10, and the upper surface thereof is formed in a curved shape. In this case, when opening and closing the changjjak 10, the corner portion of the changjjak 10 rides on the curved part 131 and smoothly moves to reduce the jamming phenomenon of the changjjak 10 and to prevent the cushion member 130 from being damaged. get it In addition, while being pressed in contact with the upper surface or the lower surface of the window jjak (10), the gap space is blocked to maintain airtightness.

In addition, the cushion member 130 may be formed by foaming a composition containing a polyolefin resin, and the polyolefin resin is, for example, low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), polypropylene. (PP), ethylene propylene diene monomer (EPDM), may be at least one selected from the group consisting of ethylene butene copolymer and ethylene octene copolymer.

As a specific example in the present invention, the polyolefin resin can be EPDM having excellent durability and excellent friction resistance and restoration property, which can prevent the freezing phenomenon that may occur in winter by reducing the moisture absorption rate by minimizing the porosity during foaming, and includes it The cushion member 130 can be soft pressed and restored during sliding movement of the window sill (10).

The composition may further include one or more selected from the group consisting of, for example, a foaming agent, a flame retardant, and a nucleating agent as an additive.

The foaming agent may be one commonly used for foam molding of the polyolefin resin, for example, may be at least one selected from the group consisting of a thermal decomposition foaming agent and a capsule foaming agent, but if it is a foaming agent advantageous for forming closed cells, it is necessarily limited it is not

Here, the closed-cell is a space in which the exchange of gas such as air (or liquid such as water) is blocked (not ventilated) (that is, it is It means a structure having a bubble).

As a concept corresponding to this, the open-cell refers to a structure in which gases are exchanged in an adjacent space because a hole is formed in a part of the cell membrane.

The flame retardant may be, for example, at least one selected from the group consisting of aluminum hydroxide, magnesium hydroxide, a hydrate of magnesium oxide/nickel oxide, and a hydrate of magnesium oxide/zinc oxide.

The nucleating agent is, for example, talc, silica, alumina, mica, titania, zinc oxide, zeolite, calcium carbonate, magnesium carbonate, barium sulfate, aluminum hydroxide, such as oxides, complex oxides, metal carbonates, metal sulfates and metal hydroxides the group consisting of It may be at least one selected from

The closed cell ratio of the cushion member 130 may be 70-90%, or 75-85%. The closed cell ratio may be measured using an air comparison hydrometer (for example, type 1000 manufactured by Tokyo Science Co., Ltd.) according to procedure C of ASTM-D2856-70. Specifically, the closed cell rate of the cushion member 130 is a sample cut into a size of 25 mmХ horizontally 25 mmХ and a thickness of 20 mm from a total of three places near the central portion and both ends of the cushion member 130 in the width direction. It was set as a sample, the closed cell ratio was computed by following formula (1) with respect to each sample, and it calculated|required as the arithmetic mean value of the closed cell ratio of three places.

Closed cell rate (%)=(Vx-W/ρ)Х100/(VA-W/ρ) ?? (One)

However, Vx, VA, W and rho are as follows.

Vx: The true volume of the sample measured by the air comparison hydrometer (cm 3; the sum of the volume of resin constituting the sample of the cushion member and the total volume of the cells in the closed cell portion in the sample.)

VA: Apparent volume (cm3) of the sample calculated from the external dimension method of the sample

W: total weight of the sample (g)

ρ: Density of the styrene-based resin constituting the styrene-based resin extruded foam (g/cm 3 )

The cushion member 130 can fundamentally prevent the water dew condensation (W) accommodated between the rails 21 from being absorbed by the cushion member 130 by having an independent cell ratio within the above range. In addition, it is possible to improve the thermal insulation performance.

The moisture absorption rate of the cushion member 130 may be 10% or less, or 8% or less. The moisture absorption rate may be calculated by changing the weight of the cushion member 130 before and after immersion after immersing the cushion member 130 in water for 12 hours. When the moisture absorption rate of the cushion member 130 exceeds the above range, the interior material may be damaged due to moisture absorption, and freezing may occur in winter, making it difficult to open and close the windows.

The apparent expansion ratio of the cushion member 130 may be 1.0-10 cc/g, or 1.3-6 cc/g. The apparent expansion ratio may be one in which the apparent density is measured in accordance with JIS K6767, and the reciprocal number is used as the expansion ratio. Specifically, the apparent density of the cushion member 130 was calculated ^{by punching the cushion member 130 to a sample size of 15 cm 3} or more, measuring the thickness and weight, and calculating the apparent density according to the following equation (2). .

Apparent　density (kg/m3)=Sample weight (kg)/{Sample thickness (m)ХSample area (m2)} ?? (2)

Thereafter, the reciprocal of the apparent density was used as the expansion ratio.

The cushion member 130 may have good flexibility while having adequate mechanical strength by having a foaming ratio within the above range.

The cover member 140 is intended to improve friction resistance so that the surface of the cushion member 130 is not damaged due to frequent friction with the window sill 10 , and may be adhered to the outer circumferential surface of the cushion member 130 . there is. The cover member 140 may be adhered through one or more selected from the group consisting of, for example, an adhesive (not shown), a double-sided tape, and a heat-sealing method by high frequency. As a specific example, the cover member 140 has excellent fixing power and may be adhered to the outer circumferential surface of the cushion member 130 through an economical adhesive.

The cover member 140 may be made of, for example, a soft cloth containing synthetic fibers or synthetic resins as a component, and as a specific example, may be made of a linex fabric having excellent friction resistance.

It is preferable that the peeling piece 100 having such a structure is installed in at least the lower groove portion 22 of the window frame 20 in which the dew condensation water (W) formed on the indoor glass window flows down and collects.

The peeling piece 100 for windows and doors according to the present invention having the configuration as described above is a lower groove portion in which dew condensation water (W) mainly flows and gathers among a pair of rails 21 provided on opposite surfaces of the window frame 20, respectively. Installed in 22, the cushion member 130 having a closed cell rate of 70-90% is attached to the base member 110 to fundamentally block water absorption and improve functionality such as thermal bridge prevention, heat insulation, sound insulation, etc. provides an effect.
