Description

Description SPACER OF PAIR GLASS

Technical Field

[1] The present invention relates to a double-sheet glass spacer, and in particular to a double-sheet spacer in which a strength of a spacer and an adiabatic performance are enhanced by integrally forming a reinforcing material made of aluminum or aluminum alloy in an inner side of a spacer and by coating an adiabatic on one outer side of the same. Background Art

[2] A spacer is used for maintaining a certain space between the double sheets of glass.

The double-sheet glass is generally used in a window frame or chassis which separates an indoor and an outdoor of a building. The double-sheet glass is used for the purpose of an adiabatic function or a soundproof function. Since a spacer is installed between the double sheets of glass, an air layer is stably supported between the same. Here, the spacer is generally made of an aluminum material.

[3] Since almost spacers are made of an aluminum material having a high heat conduction rate, and heat is conducted between the double sheets of glass. So, an adiabatic effect may disadvantageously decrease. Since the spacer does not have an elastic force, it may be transformed by means of an external force during the construction, so that it makes it impossible to use the same.

[4] For overcoming the above-described problems, as shown in Figure 1, the Korean utility model number 1994-33373 discloses a double-sheet glass spacer(hereinafter referred to as cited invention 1).

[5] As shown therein, according to the cited invention 1, there is provided a double- sheet glass spacer 10 in which a cut portion 11 is longitudinally formed on an upper center portion of the same and which has a space portion for filling a moisture resistant material at an inner side. The above double-sheet glass spacer 10 is made by means of an extrusion by using a synthetic resin as a material. A plurality of pattern protrusions are formed on a slanted part 12 of both sides of a lower side. An adhesion layer 14 is formed on both sides of the same for an adherence with both glass sheets. An adhering sheet 15 is attached to the adhesion layer 14.

[6] The above-cited invention 1 has an advantage for obtaining a desired adiabatic effect with the help of a low heat conduction rate, but it is made of a synthetic resin. So, the spacer may be easily bent when a spacer is adhered to a glass surface, and a fixed shape is unstable. So, an adhering work is very hard. The construction work may be poorly performed, and workability is bad. Since a plurality of workers are needed for stably supporting a glass plate so that a spacer is not transformed during the installation. The cost for workers increases.

[7] For overcoming the above-described problems, the Korean utility model number

0402312 discloses a double-sheet glass spacer(herein referred to as cited invention X). A reinforcing material 10a made of aluminum or aluminum alloy is integrally formed in an inner side of a spacer 20a. The spacer 20a made of a synthetic resin is formed at an outer side of the same. Through holes 21a are formed on an upper surface of the spacer 20a at regular spaces as shown in Figure 2.

[8] As shown in Figure 2, the cited invention 2 has the following problems.

[9] First, moisture may occur on a surface with through holes, namely, on a surface of the spacer inserted into the interior formed by the sheets of the glass owing to a temperature difference between the inner and outer sides. The moisture may be absorbed by means of an absorption member provided in the interior of the spacer through the through holes of the spacer, so that transparent glass without moisture or dew formation is obtained. However, since the surface with through holes is made of a synthetic resin, corrosion occurs due to a long time contact with moisture. So, a whitening phenomenon may occur in the synthetic resin, so that the size of each through hole increases, and the thickness of the surface with through holes may decrease.

[10] Second, when a temperature difference between the inner and outer sides is high in winter, moisture and dew formations increase in the interior of the sheets of glass. At this time, the spacer has a function for that. Namely, the surface of the space with through holes is made of a synthetic resin, part of the moisture is observed by means of an absorption member through the through holes, but part of the moisture may be attached on the surface of the synthetic resin owing to the characteristic of the synthetic resin, so that the attached moisture may form large size water drops, whereby water is filled in the interior formed by the double sheets of glass.

[11] Third, since all the outer surface of the spacer is made of a synthetic resin, a certain adhesive such as sealant is used on both sides and a back side(opposite side to the side with through holes) and a back side contacting with a support case such as aluminum chassis, which supports the glass. Here, the adhesive has a certain property opposite to that of the synthetic resin, so that a peeling phenomenon occurs. So, the surface of the synthetic resin has corrosion. In this case, the above adhesive temporarily functions. The sealant, which is a kind of adhesive mainly used, does not well adhere with the synthetic resin, so that a separation occurs between a glass surface and a spacer or a separation occurs between a support casing and a spacer. Disclosure of Invention Technical Problem

[12] Accordingly, it is an object of the present invention to provide a double-sheet glass spacer in which a reinforcing material 10 made of aluminum or aluminum alloy is integrally formed, and an adiabatic material is coated on part of the surface for thereby overcoming a dew formation problem of moisture and a spacer separation problem which occurs in the conventional spacer.

[13] It is another object of the present invention to provide a double-sheet glass spacer in which an adiabatic cap is coated and integrally made depending on the structure of an outer portion of a double-sheet glass spacer for thereby enhancing an adiabatic performance, and an adhering force with glass or an adhesive is enhanced, so that it is possible to enhance a sealing effect for disconnecting an outer side and air.

Technical Solution

[14] To achieve the above objects, in a double-sheet glass spacer 100 which is formed of an upper surface 120, both sides 130, a slanted surface 140 and a bottom surface, and in which a space 110 is formed in the interior of the same, and the slanted surface 140 is vent at a portion in which the both sides and the bottom surface are connected with each other, and a reinforcing member 145 is protruded from both ends of the slanted surface 140, and a plurality of through holes 125 are formed on the upper surface 120 at regular intervals, there is provided a double-sheet glass spacer characterized in that an adiabatic cap 200 integrally coats the both sides 130, the slanted surface 140 and the bottom surface 150 except on the upper surface 120.

Advantageous Effects

[15] In the present invention, there is provided an adiabatic cap able to coat both sides, a slanted surface, a bottom surface or an upper surface and both sides of a double-sheet glass spacer, respectively, which is made of aluminum or aluminum alloy, so that it is possible to prevent a dew formation phenomenon occurring in the interior formed by the double sheets of glass owing to a temperature difference. In addition, the present invention makes it possible to prevent moisture generating on a metallic spacer from being attached to an inner surface and to enhance an adhering force for sealing air from the outside and to enhance an adiabatic effect.

[31] In the present invention, in a double-sheet glass spacer 100 which is formed of an upper surface 120, both sides 130, a slanted surface 140 and a bottom surface, and in which a space 110 is formed in the interior of the same, and the slanted surface 140 is vent at a portion in which the both sides and the bottom surface are connected with each other, and a reinforcing member 145 is protruded from both ends of the slanted surface 140, and a plurality of through holes 125 are formed on the upper surface 120 at regular intervals, there is provided a double-sheet glass spacer characterized in that an adiabatic cap 200 integrally coats the both sides 130, the slanted surface 140 and the bottom surface 150 except on the upper surface 120. Mode for the Invention

[32] In the present invention, as shown in Figure 3, in a double-sheet glass spacer 100 which is formed of an upper surface 120, both sides 130, a slanted surface 140 and a bottom surface, and in which a space 110 is formed in the interior of the same, and the slanted surface 140 is vent at a portion in which the both sides and the bottom surface are connected with each other, and a reinforcing member 145 is protruded from both ends of the slanted surface 140, and a plurality of through holes 125 are formed on the upper surface 120 at regular intervals, there is provided a double-sheet glass spacer characterized in that an adiabatic cap 200 integrally coats the both sides 130, the slanted surface 140 and the bottom surface 150 except on the upper surface 120. The double-sheet glass shaper is referred to the spacer hereinafter.

[33] As shown in Figure 1, the adiabatic cap 200 is integrally coated on both sides 130, a slanted surface 140 and a bottom surface 150 of the spacer 100 in the same shape as the both sides 130, the slanted surface 140 and the bottom surface 150 of the spacer 100. The adiabatic cap 200 is made of rubber or PVC and has the same shape as the both sides 130, the slanted surface 140 and the bottom surface 150 of the spacer 100, but accommodates the both sides 130, the slanted surface 140 and the bottom surface 150 of the spacer 100. The ends of both sides of the adiabatic cap 200 are extended for being engaged by means of the end of the upper surface 120 of the spacer 100. So, the spacer 100 is installed in the adiabatic cap 200 by means of a sliding method. The space of the adiabatic cap 200 is substantially small for accommodating the both sides 130, the slanted surface 140 and the bottom surface 150 of the spacer 100, so that it very tightly accommodates the both sides 130, the slanted surface 140 and the bottom surface 150 of the spacer 100, respectively.

[34] As shown in Figure 5, as the double-sheet glass spacer is installed like the assembling and disassembling view before the spacer of Figure 7 is installed, it is possible to obtain the detailed cross section view of Figure 8 according to the present invention as shown in Figures 3 and 5.

[35] As shown in Figure 8, the bottom surface 210 of the adiabatic cap 200 supports the spacer 100 as a certain adhesive line the sealant 700 is filed into a space surface- contacting with the glass 600 installed at both sides of the spacer 100. At this time, the sealant 700 may have a poor adhering force since it contacts with rubber or PVC. In the present invention, as shown in Figures 9 and 10, a plurality of ventilation holes 215 are provided on the bottom surface 210 of the adiabatic cap 200 at regular spaces, so that the bottom surface 150 of the spacer 100 is exposed through the ventilation holes 215 formed in the adiabatic cap 200 when coating the adiabatic cap 200 to the spacer 100. Namely, the bottom surface 150 of the spacer 100 made of aluminum or aluminum alloy is exposed, so that it can be strongly adhered with the sealant 700.

[36] So, the space 100 is not escaped with the help of a strong force and sealing operation with respect to the glass 600 installed at both sides of the spacer 100. In addition, it is possible to prevent external moisture from being inputted into the interior formed by the double sheets of glass.

[37] A reinforcing member 145 is protruded from both ends of the slant surface 140 of the spacer 100 for enhancing a tensional force owing to the adhering force with the sealant 700. An adhesive is coated on both sides of the adiabatic cap 200 including an adhering work along with the sealant 700, so that it is possible to enhance an adhering force with the glass 600.

[38] As shown in Figures 12 and 13, the adiabatic cap 200 is integrally coated on the upper surface 120 and the both sides 130 of the spacer 100 in the same shape as the upper surface 120 and the both sides 130 of the spacer 100, and a plurality of through holes 225 are formed on the upper surface 220 of the adiabatic cap 200 at regular spaces.

[39] As the adiabatic cap 200 is coated on the upper surface 120 and the both sides 130 of the spacer 100, a moisture absorption member 300 like a silica gel provided in the space 110 of the spacer 100 made of aluminum or aluminum alloy absorbs moisture generating on the surface of the glass 600. Owing to the moisture occurring due to a temperature difference of the spacer, micro moistures are attached on the upper surface 120 of the spacer 100. In this case, the moisture absorption member 300 is unable to remove the moisture. In the present invention, the adiabatic cap 200 covering the upper surface 120 of the spacer 100 is provided, so that it is possible to prevent the moisture absorbed by means of the moisture absorption member 300 provided in the space 110 of the spacer 100 from being outputted to the outside.

[40] Namely, as the moisture is absorbed by means of the moisture absorption member

300 accommodated in the space 110 of the spacer 100, a temperature difference occurs in the space 110, so that moistures are attached on the upper surface 120 of the spacer 100 because the spacer 100 is made of a metallic material. So, the adiabatic cap 200 is coated on the upper surface 120 of the spacer 100 for decreasing a short time temperature difference in the space 110 of the spacer 100 in order to prevent the moistures from being attached on the upper surface 120 of the spacer 100.

[41] As shown in Figures 4 and 12, a right- angle shape connection member 400 having a plurality of engaging shoulders 410 at both ends is inserted into the interior of the space 110 of the spacer 100, so that a rectangular spacer assembly 500 having the same size as the window frame or chassis is made. It is attached to both sides of the adiabatic cap 200 using an adhesive, and the glass 600 is attached to both sides of the same. An adhesive such as the sealant 700 is coated in the space formed between the double sheets of glass 600 being symmetrical to the bottom surface 150 of the spacer 100 for thereby finishing the double-sheet glass. Industrial Applicability [42] In the present invention, there is provided an adiabatic cap able to coat both sides, a slanted surface, a bottom surface or an upper surface and both sides of a double-sheet glass spacer, respectively, which is made of aluminum or aluminum alloy, so that it is possible to prevent a dew formation phenomenon occurring in the interior formed by the double sheets of glass owing to a temperature difference. In addition, the present invention makes it possible to prevent moisture generating on a metallic spacer from being attached to an inner surface and to enhance an adhering force for sealing air from the outside and to enhance an adiabatic effect.

[43] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
