The present invention relates to a spacer for a multilayer glass, and more particularly to a spacer for a multilayer glass to be able to combine a plurality of glass at a predetermined interval.

Multi-layered glass is a combination of two or more pieces of glass at predetermined intervals, and a spacer is used to bond while maintaining the gap between the glass. The spacer is generally located along the edge of the glass between the two sheets of glass.

In general, since the laminated glass has a space formed between the inner and outer glass, not only does it minimize the loss of room energy compared to the single glass, but the surface temperature of the inner glass decreases relatively less even though the outer temperature is lowered. Dew condensation is suppressed. In addition, it is excellent in sound insulation performance can effectively block the transmission of noise between the indoor and outdoor. As a prior art for providing such a laminated glass there is Republic of Korea Utility Model No. 20-0296701.

However, the conventional multilayer glass has the following problems.

That is, in the conventional multilayer glass spacer, a desiccant is placed inside to absorb moisture generated in the space between the multilayer glass. To this end, the spacer is cut or punched to form a ventilation hole so that the space provided with the desiccant and the space inside the multilayer glass communicate with each other. However, performing the punching process or the cutting process in this way increases the manufacturing man-hours of the spacer, thereby increasing the manufacturing cost.

In addition, when the punching process or the cutting process is performed on the spacer as described above, the surface of the portion is not good. Therefore, there is a need to perform a separate surface treatment process after performing the punching process or the cutting process.

The conventional multilayer glass spacer is different in the case of combining two pieces of glass and in the case of combining three pieces of glass by placing one more glass in the middle. That is, in the case of manufacturing two sheets of laminated glass and in the case of manufacturing three sheets of laminated glass, the spacers are different in configuration, and the spacers must be manufactured separately.

On the other hand, the conventional multilayer glass spacer is mainly made of a metal material such as aluminum, it is relatively difficult to bond with the glass, there is also a problem that heat transfer easily occurs to reduce the thermal insulation performance of the laminated glass.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, by combining the intermediate bar formed by extrusion into a frame made by extruding synthetic resin in the longitudinal direction, the wet and dry formed on both ends of the frame in the longitudinal direction The communication slit is formed so that the space communicates with the outside.

Another object of the present invention is to provide a spacer capable of combining two pieces of glass and three pieces of glass by changing the direction in which the middle bar is inserted into the frame.

Another object of the present invention is to allow the spacer to elastically deform to some extent against the external force acting on the glass.

According to the features of the present invention for achieving the object as described above, the present invention is extrusion molded into a synthetic resin material, the glass is attached to both sides and the bar insertion portion is formed to be opened to the outside along the longitudinal direction therein and wet and dry inside The wet and dry space is formed between the frame formed by the wet and dry space, and is inserted into the bar inserting portion in the longitudinal direction of the frame to be extruded and inserted into the bar inserting portion and the wet edge is inserted into the bar inserting portion. And an intermediate bar forming a communication slit allowing the space to communicate with the outside.

When the inside of the frame is viewed in cross section, the wet and dry spaces are formed at both ends thereof, and the wet and dry spaces are partitioned from the bar insertion portion by the intermediate bar.

Hook ribs having a hooking jaw extending in the longitudinal direction of the frame are formed to face each other at both ends of the bar insertion part inside the frame, and both sides of the middle bar are selectively selected at the hooking jaw of the hooking rib at positions adjacent to the corners, respectively. The first and second locking ribs protruding from each other are formed to protrude.

The inside of the middle bar is formed so that the glass insertion portion is opened in one side in the longitudinal direction, and the inlet of the glass insertion portion is formed to protrude close contact with each other.

An inclined surface is formed along one end of the outer surface of the frame facing the glass, thereby forming a space in which a sealant is applied between the glass and the outer surface of the frame.

According to the present invention having such a configuration, as the frame and the middle bar are coupled, the wet and dry spaces formed at both ends in the longitudinal direction of the inside of the frame can communicate with each other through the communication slit. Moisture absorption is maximized by communicating with the space, and two or three pieces of glass can be selectively combined with one spacer, and a communication slit formed between the frame and the middle bar provides a space where the frame can elastically deform. There is an advantage that the frame can be flexibly absorbed by the external force acting on the glass.

 Hereinafter, exemplary embodiments of a multilayer glass spacer according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial cross-sectional perspective view showing the glass is bonded using a preferred embodiment of the spacer according to the present invention, Figure 2 is a cross-sectional view showing the glass is bonded using the spacer of the present invention, 3A and 3B illustrate cross-sectional views of the frame and the intermediate bar constituting the present invention.

As shown in these figures, the frame 10 forms the appearance and skeleton of the spacer of the present invention. The frame 10 is made by extrusion molding so that the cross-sectional shape is constant. The frame 10 is made of a synthetic resin material, a material having good thermal insulation performance is used. The material constituting the frame 10 may be polyamide. Of course, in addition to polyamide, various synthetic resins can be used as long as the insulation performance and strength can be maintained.

The shape of the frame 10 is roughly similar in cross section to a rectangle, and in practice, two adjacent corner portions are inclined so that the cross section is hexagonal. A portion in which the bar insertion portion 13 to be described below is formed in one side of the frame 10 is formed by opening the inside and the outside in communication with each other.

When the frame 10 is cut in the transverse direction with respect to the longitudinal direction, first and second wet and dry spaces 11 and 11 'are formed at both ends thereof. The cross-sectional shape of the wet and dry spaces 11 and 11 'is approximately trapezoidal. Of course, the cross-sections of the wet and dry spaces 11 and 11 'do not necessarily have to be trapezoidal and may have various shapes. The desiccant 12 is filled in the wet and dry spaces 11 and 11 '. Silica gel may be used as the desiccant 12. The silica gel, which is the desiccant 12, has a diameter of about 1.3 to 2 mm.

A bar insertion portion 13 is formed along the longitudinal center of the frame 10. The bar insertion portion 13 is formed along the middle of the frame 10 corresponding to between the wet and dry spaces 11 and 11 ', and an intermediate bar 20 to be described below is inserted.

A hook rib 14 protrudes in the frame 10 to insert the wet and dry spaces 11 and 11 ′ and the bar insertion portion 13 and the intermediate bar 20 to be described below. . The hook ribs 14 are formed to face each other so as to partition the bar insertion portion 13 and the wet and dry spaces 11 and 11 '. Hanging jaw 15 is formed at the tip of the hook rib 14 to protrude in a direction facing each other. The hanger 15 is for fixing the intermediate bar 20 to be described below.

Inclined surfaces 18 are formed along one end of the outer surface of the frame 10 facing the glass 30 and 32. The inclined surface 18 serves to form a space in which the sealant 36 can be applied between the glass 30 and 32 and the frame 10 to be described below. That is, a space having a triangular cross section is formed between the inclined surface 18 of the frame 10 and the glass 30, 32.

The intermediate bar 20 is also produced by extrusion. The material forming the intermediate bar 20 is preferably a synthetic resin such as polyamide. However, it can also be made of metal, such as aluminum.

The intermediate bar 20 is inserted into the bar insertion portion 13 of the frame 10 to shield the wet and dry spaces 11 and 11 '. Of course, most of the wet and dry spaces 11 and 11 'are shielded from the outside by the intermediate bar 20 is inserted into the bar inserting portion 13, but between the frame 10 and the middle bar 20 The gap, that is, the communication slit 21 is formed. The communication slit 21 serves to communicate the wet and dry spaces 11 and 11 'with the outside. The communication slit 21 is formed continuously in one direction such as the frame 10 and the middle bar 20. The opening width of the communication slit 21 should be smaller than the diameter of the desiccant 12, preferably about 0.3 to 0.7 mm.

The middle bar 20 has a substantially cross section of a quadrangular shape, more precisely, a 'c' shape in which one side is opened. Inside the middle bar 20 is formed a glass insertion portion 22 long in the longitudinal direction of the middle bar (20). The glass inserting portion 22 is opened through one surface of the intermediate bar 20. At both ends of the inlet of the glass inserting portion 22, the contact protrusions 24 are formed to face each other in the longitudinal direction of the middle bar 20. The close contact portion 24 is formed such that the width of the cross section becomes smaller toward the tip, making the inlet width of the glass inserting portion 22 relatively narrower than other portions. The adhesion protrusion 24 also serves to support the surface of the intermediate glass 34 in close contact.

First and second locking ribs 26 and 26 'are formed at positions adjacent to four corners in the cross section of the middle bar 20 to protrude outwardly. The locking ribs 26 and 26 'are formed to protrude in the direction of the wet and dry spaces 11 and 11' on both sides of the intermediate bar 20, respectively. The locking ribs 26 and 26 'are formed long in the longitudinal direction of the middle bar 20.

The locking ribs 26 and 26 'are hooked on the hooking jaw 15 of the hook rib 14 so that the intermediate bar 20 is not arbitrarily separated from the bar inserting portion 13 of the frame 10. Do it. To this end, the width of the locking ribs 26 and 26 'is preferably made equal to the height from the inner surface of the frame 10 to the hooking jaw 15.

In addition, the locking ribs 26 and 26 'may vary the width of the communication slit 21 by adjusting the projecting degree thereof. One of the first and second locking ribs 26 and 26 'is hooked on the hook rib 14, and the other is positioned to form a predetermined distance with one side of the frame 10 so that the communication slit 21 ).

As such, when the locking ribs 26 and 26 'are formed on both sides adjacent to the edges, that is, the locking ribs 26 and 26' are formed to extend in the longitudinal direction along the upper and lower ends of both side surfaces of the intermediate bar 20. When the intermediate bar 20 can be inserted into the bar inserting portion 13 in a different direction.

The outer glass 30 and the inner glass 32 are attached to both sides of the frame 10 by an adhesive 33, respectively. In addition, a sealant 36 is filled in the space between the outer glass 30, the inner glass 32, and the inclined surface 18 of the frame 10. Silicone may be used as the sealant 36. The sealant 36 simultaneously performs the bonding and sealing role between the frame 10 and the glass 30, 32. The edge of the middle glass 34 positioned between the outer glass 30 and the inner glass 32 is inserted into the glass inserting portion 22 of the middle bar 20.

Reference numeral 38 in the figure is a setting block.

Hereinafter, the effect | action of the spacer for multilayer glass by this invention which has a structure as mentioned above is demonstrated in detail.

First, it will be described to make a triple laminated glass using the spacer of the present invention. In order to combine the glass 30, 32, 34 in three, as shown in Figure 2, the middle bar 20 to the frame 10 so that the glass insert portion 22 of the middle bar 20 is visible from the outside (10) Should be inserted into the bar insert (13).

That is, the intermediate bar 20 is inserted into the bar insertion portion 13 of the frame 10 produced by extrusion. In this case, the first locking rib 26 of the intermediate bar 20 is hooked to the hooking jaw 15 of the hook rib 14, and the second locking rib 26 ′ is the bar insertion portion 13. The communication slit 21 is formed to face both ends of the inlet.

When the intermediate bar 20 is inserted into the bar insertion portion 13 of the frame 10, the wet and dry spaces 11 and 11 ′ are external only (eg, between the glass 30 and 32) through the communication slit 21. Communication with space). Of course, this is the case when a separate blocking process is applied to both ends of the frame 10.

In this way, in the state in which the middle bar 20 is inserted into the frame 10, they are cut to the desired length. However, before inserting the intermediate bar 20 into the frame 10, they can be cut to a desired length in advance. Next, the desiccant 12 is put into the wet and dry spaces 11 and 11 '. The desiccant 12 is put through one end of the frame 10 that is not blocked.

The spacer is cut to a desired length and made into a shape corresponding to the shape along the edges of the glass 30, 32. For example, it may be made into a rectangular frame shape.

As shown in FIG. 2, in order to bond the three glasses 30, 32, and 34, the intermediate glass 34 is inserted into the glass inserting portion 22, and the adhesive 33 is formed on both sides of the frame 10. Using the outer glass 30 and the inner glass 32 is bonded. A sealant 36 is applied to a space between the glasses 30 and 32 and the inclined surface 18 of the frame 10.

On the other hand, Figure 4 is shown to combine the two glass (30, 32) using the spacer of the present invention. To this end, when the intermediate bar 20 is inserted into the bar inserting portion 13 of the frame 10, the entrance of the glass inserting portion 22 faces the inner surface of the frame 10. That is, the second locking rib 26 'is hooked on the hooking jaw 15 of the hook rib 14, and the first locking rib 26 is of the bar insertion portion 13 of the frame 10. The inlet edge and the communication slits 21 are formed to face each other.

In this case, even when the intermediate bar 20 is coupled to the bar insertion portion 13 of the frame 10, only the communication slit 21 is visible and the glass insertion portion 22 is not visible to the outside.

When the outer glass 30 and the inner glass 32 are attached to the both sides of the frame 10 by using an adhesive 33, respectively, as shown in FIG. 4, the two glasses 30 and 32 are spacers. Can be combined using.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

For example, the shape of the wet and dry spaces 11 and 11 ′ may be variously formed, and may be configured to surround three surfaces of the bar insertion portion 13.

And, the width of both ends of the cross section of the frame 10 on the basis of the bar insert 13 may be configured differently. This is to relatively increase the cross-sectional width of the frame 10 on the side to which the outer glass 30 is attached. By doing so, it is possible to make the external temperature relatively less affected.

The shape of the intermediate bar 20 is not limited to that of the illustrated embodiment, but the first and second locking ribs 26 and 26 'are formed, and the bar inserting portion 13 of the frame 10 in the opposite direction. It can be anything that can be inserted into.

The shape of the space formed between the glass and the inclined surface of the frame is not limited to that of the illustrated embodiment, but may be in various shapes. That is, the inclined surface portion of the frame can be configured in various shapes.

According to the spacer for multilayer glass according to the present invention as described in detail above, the following effects can be expected.

In the present invention, the middle bar is longitudinally coupled to the frame made of synthetic resin so that the wet and dry space formed inside the frame communicates with the outside through a communication slit formed between the middle bar and the frame. According to such a configuration, since the communication slit is not formed through a separate processing process, but is formed by combining the intermediate bar and the frame, the manufacturing process of the spacer can be more easily performed.

In addition, since the frame is made of synthetic resin, the heat insulation effect is relatively higher, and the communication slit is formed longer in the longitudinal direction of the frame and the middle bar, so that the communication area between the wet and dry space and the outside becomes relatively large, and the moisture-proof effect is further increased. It becomes bigger.

In addition, in the present invention, two sheets of glass and three sheets of glass may be combined by changing the direction in which the middle bar is inserted into the frame. Therefore, the spacer of the present invention has an effect that the compatibility can be produced to be able to manufacture a relatively various types of laminated glass.

On the other hand, the spacer of the present invention, when the intermediate bar is inserted into the frame, the gap as much as the communication slit is formed between the middle bar and the frame, the gap of the communication slit can absorb the force when the force acts on the spacer by the glass. The frame can be elastically deformed so that it is elastic. Therefore, the durability of the adhesive state between the laminated glass and the spacer is relatively increased.

In addition, since the frame is made of synthetic resin, it is relatively easy to attach with glass using an adhesive, compared to the case of using a metal frame, and the effect of making a rugged multilayer glass at a relatively low cost is relatively low. have.
