Description

  The present invention relates to a joinery in which glass is provided in an opening formed by a frame framed in a rectangular shape.

  Conventionally, as a fitting having glass provided in an opening formed by a rectangular frame, for example, a fixed window in which a window glass is fitted in a quadruple frame-shaped window frame body is known (for example, Patent Document 1). The fixed window in which such a window glass is fitted is provided on the outdoor side surface of the presser frame by applying the peripheral inner surface of the window glass to the outdoor side surface of the presser bar protruding from the indoor inner peripheral edge of the window frame body. It is shown that the window glass is adhered to the presser bar by the adhesive filled in the recess without any gap.

Japanese Utility Model Publication No. 4-84696

  Because the window glass and the presser foot (window frame body) are made of different materials, the linear expansion coefficient is different. Therefore, the window glass and the presser foot are relatively displaced in the direction along the surface of the window glass due to temperature changes. A shearing force may act on the adhesive that bonds the glass and the presser foot. At this time, when the window glass is bonded with an adhesive filled in the recess of the presser bar without any gap as in the conventional fixed window, the window glass and the presser bar are relatively aligned in the direction along the surface of the window glass. When displaced, there is a problem that the adhesive may be damaged by the edge of the presser bar that forms the recess.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the fitting with which an adhesive agent is hard to be damaged even if glass and a frame displace relatively.

In order to achieve such an object, the joinery of the present invention is a joinery having a frame body that is rectangularly framed to form an opening, and glass provided in the opening, wherein the glass has a peripheral end portion. Covers the opening facing the frame over the entire circumference, and forms the opening, and is bonded to the frame with an adhesive at a position spaced from the edge of the frame to the outer peripheral side. The adhesive is not bonded to the peripheral edge of the glass, and the adhesive is started to be supplied from a predetermined position by the relative movement of the adhesive supply unit and the frame body. And the supply is terminated at the predetermined position after surrounding the opening, and the predetermined position is located at a straight line portion between a pair of corner portions in the rectangular frame. It is a joinery characterized by.

According to such a fitting, even if the peripheral edge of the glass is in contact with another member, it is possible to provide a gap on the peripheral side of the glass from the adhesive. For this reason, even if the adhesive is deformed to the peripheral side of the glass due to the shear deformation due to the difference in linear expansion coefficient, it is possible to prevent the adhesive from being damaged by the other member abutted.
Also, when the adhesive is circled so as to surround the opening and is supplied to the rectangular frame body, the relative movement speed is lower when the adhesive is supplied to the corner portion than the rectangular linear portion. The amount of adhesive supplied per predetermined area is greater at the corners. In addition, when the supply of the adhesive is started, the pressure in the supply unit may increase, and the supply amount of the adhesive may increase. For this reason, if the corner portion is set as the supply start position, the supply amount to the corner portion becomes excessive, and there is a possibility that no gap is provided between the supplied adhesive and the contact protrusion. Therefore, by making the supply start position a rectangular linear portion as in the above joinery, it is possible to prevent the concentration of the adhesive and to provide a gap between the supplied adhesive and the contact protrusion.

In the foregoing joinery, the frame body, the edge forming the opening, it is desirable from the one side toward the center projecting the glass in the expected direction is have a contact protrusion that contacts .
According to such a joinery, the adhesive that bonds the glass and the frame body and the contact protrusion are spaced apart from each other on the outer peripheral side with respect to the contact protrusion with which the glass is contacted. Even if a shearing force acts on the adhesive due to the difference in rate, the adhesive can be prevented from coming into contact with the contact protrusion or can be made difficult to contact. For this reason, it is possible to prevent the adhesive from being damaged by the contact protrusion. That is, it is possible to provide a joinery in which the adhesive is not damaged even when the glass and the frame are relatively displaced.

In this joinery, it is preferable that the linear portion of the frame body at the predetermined position is the linear portion on the long side of the rectangular shape formed by the frame body.
The deformation of the adhesive due to the difference in linear expansion coefficient is greatly deformed as the length of the member is long. For this reason, in the case of a frame having different vertical and horizontal lengths, the longer one in the vertical and horizontal lengths is greatly deformed. The adhesive is supplied along the longitudinal direction of each frame member constituting the frame, and when the adhesive is damaged by shear deformation, the shearing force acts in a direction crossing the supply direction. For this reason, since the shear deformation that may damage the adhesive is a case where the short side intersects in the vertical and horizontal lengths, a supply that is likely to be supplied with a large amount of adhesive on the shorter frame material side By setting the supply start position on the frame material side that is a long straight portion so that the start position is not arranged, it is possible to provide a joinery having higher durability against shear deformation.

  According to the present invention, it is possible to provide a joinery in which the adhesive is not easily damaged even when the glass and the frame are relatively displaced.

  Hereinafter, a fitting according to an embodiment of the present invention will be described with reference to the drawings.

  The joinery 1 according to the present embodiment is a joinery 1 that constitutes a raising and lowering window capable of opening and closing a space in which a shoji moves in the vertical direction and communicates indoors and outdoors as shown in FIGS. 1 and 2. In the following description, when the joinery 1 is viewed from the indoor side, the vertical direction is the vertical direction, the horizontal direction is the horizontal direction or finding direction, and the depth direction that is the indoor / outdoor direction is the prospective direction. In addition, even when the shoji and the frame are described as a single unit, the vertical direction, the indoor side, the outdoor side, the direction of the finding, and the prospect based on the state in which the shoji and the frame are attached to the frame. Indicates direction.

  The joinery 1 includes a window frame 3 attached to the housing 2, a fixed shoji 5 provided so as not to move by closing an upper region in the space inside the window frame 3, and a lower frame that moves vertically. It has the movable shoji 10 provided to open and close the area. In addition, the fixed shoji 5 is disposed in a region outside the room from approximately half of the window frame 3 in the prospective direction, and the movable shoji 10 is disposed in a region on the indoor side from approximately half of the window frame 3.

  The fixed shoji 5 and the movable shoji 10 are made of four eaves 6a and 11a, which are resin-made extruded members, by cutting both ends of each eaves 6a and 11a at 45 degrees, and different eaves 6a and 11a. The end portions of each other are butted and joined to form the casings 6 and 11 as rectangular frames. Glass 4 is provided in the openings 6b and 11d surrounded by the rectangular casings 6 and 11. Since the structure in which the fixed shoji 5 and the movable shoji 10 hold the glass 4 is the same, here, the case 11 of the movable shoji 10 will be described as an example.

  Each saddle member 11a that constitutes the casing 11 of the movable shoji 10 projects to the inner peripheral side in the inner region of the inner casing 12 on the inner peripheral side of the casing 11, and the main body 12 that forms a hollow portion communicating in the longitudinal direction. The glass abutting portion 13 where the glass 4 is abutted from the outside of the room, and the recessed portion in the inner peripheral side of the housing 11 and the region outside the outdoor, and the glass 4 facing the glass abutting portion 13. And a pressing edge mounting portion 14 to which a pressing edge 18 for holding is mounted.

  Then, the casing 11 in which the four casings 11a are framed in a rectangular shape is formed on the inner peripheral side of the casing main body 12 connected in a rectangular shape, and the glass contact portion 13 protrudes from the center to the indoor side in the prospective direction. Is formed over the entire circumference, and a groove-shaped pressing edge mounting portion 14 provided along the longitudinal direction of each collar member 11a is provided on the outer peripheral edge of the inner peripheral portion of the casing 11 on the entire periphery. It is provided across. In addition, the lower arm 10a is provided with a grip 15 for projecting inwardly and moving the movable shoji 10 up and down.

  In the glass 4, the peripheral portion of the surface 4 a facing the room is in contact with the glass contact portion 13 of the housing 11 over the entire circumference, and the peripheral portion of the surface 4 b facing the outdoor space is in contact with the pressing edge 18. At this time, a seal material 18a made of a soft resin is provided at a portion of the pressing edge 18 on the indoor side, that is, a portion facing the glass 4, and the glass 4 attached to the housing 11 is covered with the seal material 18a. It is pressed against the glass contact portion 13 by the pressed edge 18 and is held between the press edge 18 and the glass contact portion 13. Further, between the lower end 4c of the glass 4 and the upper surface 11b of the lower frame (lower frame) 10a, and the left and right end portions 4d of the glass 4 and the inner side surface of the left and right vertical frames (left and right frame) 10b. A setting block 19 for determining the position of the glass 4 in the vertical direction and the position in the direction of finding is interposed between the glass 11c.

  As shown in FIG. 3, the glass abutting portion 13 includes an abutting projection 13a with which the edge on the inner peripheral side of the opening 11d formed by the housing 11 is slightly projected outward and the glass 4 abuts. And an indoor side wall portion 13b that connects the bag main body 12 and the contact protrusion 13a. That is, the outdoor side surface 13c of the indoor side wall portion 13b is located slightly on the indoor side with respect to the outdoor side edge of the contact projection 13a, and the outdoor side surface 13c of the indoor side wall portion 13b and the glass 4 are bonded. The glass 4 is bonded to the housing 11 with the agent 20 interposed.

  The adhesive 20 is, for example, a moisture curable reactive hot melt adhesive or a UV combined reactive hot melt adhesive, and the adhesive 20 is supplied to the outdoor side surface 13c of the indoor side wall portion 13b of the rectangular casing 11. In this state, the glass 4 is brought into contact with the contact protrusion 13a and bonded thereto. For this reason, the thickness of the adhesive 20 in a state of being interposed between the glass 4 and the outdoor side surface 13c is aligned with the height at which the contact protrusion 13a protrudes from the outdoor side surface 13c of the indoor side wall portion 13b to the outdoor side. ing.

  In a state where the glass 4 is bonded to the housing 11, the adhesive 20 and the contact protrusion 13a are spaced apart in the vertical direction, and a gap 22 is provided between the adhesive 20 and the contact protrusion 13a. It has been. In addition, a non-bonded region 4 f is provided on the outer peripheral end of the glass 4 on the outer peripheral side of the adhesive 20, that is, on the outer peripheral side of the region 4 e bonded with the adhesive 20. For this reason, even if the setting block 19 or the like as an example of another member protrudes from the glass 4 to the indoor side, the gap 24 is also provided between the adhesive 20 and the setting block 19.

  As shown in FIG. 4, the adhesive 20 that bonds the glass 4 to the housing 11 has a nozzle 30 as an adhesive supply unit for supplying the adhesive 20 and the housing 11 while moving relative to each other. The adhesive 20 is discharged from 30 and supplied to the housing 11. Specifically, for example, the casing 11 formed in a rectangular shape is first arranged so that the outdoor side surface 13c of the indoor side wall portion 13b faces upward. Next, it arrange | positions so that the nozzle 30 may be located in the longitudinal direction of the housing | casing 11, ie, the longer outer material 13c (vertical rod in this embodiment) of the length of length and width, on the outdoor side surface 13c. At this time, the nozzle 30 is arranged near the center in the longitudinal direction of the vertical rod 10b. Further, the nozzle 30 is arranged so that the adhesive 20 supplied from the nozzle 30 is supplied to the inner peripheral edge of the casing 11, that is, the position away from the contact protrusion 13a of each casing 11a. At this time, the positions where the nozzles 30 are arranged are the supply start position and the supply end position (hereinafter referred to as supply start end position) X of the adhesive 20.

  Thereafter, while supplying the adhesive 20 from the nozzle 30 at a constant speed, the nozzle 30 is moved relative to the contact protrusion 13a while being spaced apart from the contact protrusion 13a. At this time, the nozzle 30 is moved at a reduced speed at the rectangular corner. When the nozzle 30 makes a round along the contact protrusion 13a and returns to the supply start end position X, the movement of the nozzle 30 is stopped and the supply of the adhesive 20 is also stopped.

  According to the fitting 1 of the said embodiment, the adhesive 20 which adhere | attaches the glass 4 and the housing | casing 11 in the outer peripheral side from the contact protrusion 13a with which the glass 4 is contacted, and the contact protrusion 13a are intervals. Therefore, even if the adhesive 20 is sheared and deformed as shown in FIG. 5, for example, due to the difference in linear expansion coefficient between the glass 4 and the brazing material 11a, the deformation of the adhesive 20 is bonded to the contact protrusion 13a. It is possible to absorb in the gap 22 between the agent 20. For this reason, even if the adhesive 20 is deformed to the contact protrusion 13a side, the adhesive 20 is difficult to contact with the contact protrusion 13a, so that the contact 20 can be prevented from being damaged by the contact protrusion 13a. Is possible. That is, it is possible to provide the fitting 1 in which the adhesive 20 is not easily damaged even when the glass 4 and the casing 11 are relatively displaced.

  Even if the peripheral edge of the glass 4 is in contact with another member such as the setting block 19 or the like, the gap 4 is provided on the peripheral side from the adhesive 20 of the glass 4. Even if the adhesive 20 is deformed to the peripheral side of the glass 4 due to shear deformation due to the difference in the linear expansion coefficient, it is possible to prevent the adhesive 20 from being damaged by other members that are in contact with each other. is there.

  As described above, the adhesive 20 goes around the opening 11d and is supplied to the rectangular casing 11, and the relative movement speed is slower when the adhesive 20 is supplied to the corner portion than the rectangular straight portion. The amount of the adhesive 20 supplied per predetermined area is larger in the corner portion as shown in FIG. Moreover, since the pressure in the hose (not shown) connected to the nozzle 30 and the nozzle 30 is often increased when the supply of the adhesive 20 starts, the supply amount of the adhesive 20 may increase even when the supply starts. is there. Furthermore, since the supply start position of the adhesive 20 is also the supply end position, the adhesive immediately before the end of supply is discharged onto the adhesive 20 discharged at the start of supply, and more adhesive 20 is supplied. There is a high possibility of being. For this reason, the supply start end position X is set as a linear portion located between the pair of corner portions in the rectangular casing 11 to prevent the adhesive 20 from further concentrating on the corner portions and supplied. It is possible to prevent the gap 22 between the adhesive 20 and the contact protrusion 13a from being filled.

  Further, the deformation of the adhesive 20 due to the difference in the linear expansion coefficient between the glass 4 and the brazing material 11a is greatly deformed when the length of the brazing material 11a is long. For this reason, in the case of the casing 11 having different vertical and horizontal lengths, the longer one in the vertical and horizontal length is greatly deformed. Since the adhesive 20 is supplied along the longitudinal direction of the respective ribs 11a constituting the casing 11, the shear deformation in which the adhesive 20 is damaged by the contact protrusion 13 intersects the supply direction. Occurs in the direction. That is, since the shear deformation of the adhesive 20 is greatly deformed in the shorter length and width, the supply start / end position X at which more adhesive 20 is likely to be supplied is not disposed on the shorter saddle member 11a side. Moreover, it is possible to provide the joinery 1 with higher durability against shear deformation by setting the supply start end position X on the side of the saddle member 11a which is a long linear portion. At this time, since the supply start end position X of the adhesive 20 is set near the center in the longitudinal direction of the vertical rod 10b having the longer vertical and horizontal lengths, the adhesive supplied to the supply start end position X It is possible to prevent the adhesive 20 supplied to the corner portion 20 from being mixed and spreading.

  In the said embodiment, although the joinery 1 was used as the joinery which comprises a raising and lowering window, it is not restricted to this, The peripheral edge part of glass is a frame-shaped member, such as a sliding window, a single-drawing window, a swing type window, a FIX window Any joinery can be used as long as it is bonded.

  Moreover, in the said embodiment, although the example in which glass was adhere | attached on the housing | casing as a frame was demonstrated, glass may be adhere | attached on frame bodies, such as a window frame.

  Further, when supplying the adhesive 20 for bonding the glass 4, the adhesive 20 may be supplied while fixing the nozzle 30 and moving the member such as the housing 11. Moreover, you may supply the adhesive agent 20 to the glass side, without supplying to frame-shaped members, such as a collar.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
