Description

  The present invention relates to a glazing channel, a glazing with a glazing channel and a sash.

  A plate-like body such as a glass plate or a resin plate is attached with a glazing channel interposed in order to securely fix it to a groove in a sash (frame) while maintaining watertightness.

  The glazing channel disclosed in Patent Document 1 is integrally formed into a substantially U-shaped cross section by a hard resin portion having a shape-retaining property and a soft resin portion having a sealing property. It is. When assembling the sash, first, the glazing channel is attached to the peripheral portion of the plate-like body, and then the peripheral portion of the plate-like body is fitted into the groove of the ridge through the glazing channel. As a result, the sash is assembled. The glazing channel is made of a resin such as vinyl chloride resin or urethane resin, and also has a function as a buffer material for the plate-like body.

  On the other hand, Patent Document 2 discloses a wrinkle with a glazing channel in which a glazing channel and a wrinkle are integrally formed. In the glazed channel-attached ridge, a soft resin glazing channel is integrally formed on the opposing inner wall surface of the ridge made of hard resin. According to the scissors with glazing channels, the sash can be assembled simply by fitting the peripheral portion of the plate-like body into the trough groove, so that the sash assembly workability is improved compared to the glazing channel of Patent Document 1. Has been.

  The glazing channel of Patent Document 2 is a soft elastic body called a fin portion, and a contact portion with the plate-like body is formed in an arc shape. A base end portion of the fin portion is fixed to the inner wall surface of the flange, and a tip portion of the fin portion is suspended toward the bottom wall surface of the flange. Note that the glazed channel-attached bag is known in Patent Documents 3 and 4 in addition to Patent Document 2.

JP 2007-211152 A JP 2007-224565 A JP 2008-274605 A Japanese Utility Model Publication No. 57-52562

  The glazing channel that is separate from the ridge disclosed in Patent Document 1 and the glazing channel that is integrated with the ridge disclosed in Patent Documents 2 to 4 (fin portion) are both fin portions ( In Patent Literature 1, a plate-like body is sandwiched and held by a soft lip). Since the fin portion has an arc shape at the contact portion with the plate-like body, the contact form between the plate-like body and the glazing channel is a line contact along the edge of the plate-like body. For this reason, the plate-like body holding force of the glazing channel cannot be said to be strong, and the glass plate may wobble with respect to the ridge during the sash opening operation.

  Therefore, in the conventional glazing channel, the gap between the pair of opposing fin portions is narrowed in order to increase the plate-like body holding force.

  However, when the gap is narrowed, a large force (hereinafter referred to as a fitting force) is required when the plate-like body is fitted into the glazing channel, so that there is a problem that the assembling workability of the sash is deteriorated. In addition, when the plate-like body is fitted into the glazing channel, the plate-like body holding force of the glazing channel can be obtained only by line contact as described above. Become smaller.

  In other words, the conventional glazing channel requires a large fitting force, so that the assembly workability of the sash is poor, and the pull-out force is small, so that the plate-like body wobbles against the wrinkles. was there. In addition, although the said pulling force can be raised, so that the thickness of a glazing channel is thickened, there existed a problem that the said fitting force became still higher by this.

  The present invention has been made in view of such circumstances. The glazing channel in which the assembling workability of the sash is improved and the plate-like body holding force is improved, the scissors provided with the glazing channel, and the scissors An object of the present invention is to provide a sash having a plate-like body attached thereto.

  In order to achieve the above object, the present invention provides a glazing channel which is attached to the opposite inner wall surfaces of a saddle having a concave cross section provided with an insertion groove into which an edge of a plate-like body is inserted. In a glazing channel of a soft material, the end portion of which is fixed to the inner wall surface and the front end portion of the glazing channel is disposed to face the bottom wall of the ridge, the glazing channel includes a plane portion that is in surface contact with the plate-like body. A glazing channel is provided.

  According to the present invention, the plate-like body is formed by the flat portion provided in the glazing channel without unnecessarily reducing the gap between the pair of fin portions and without unnecessarily increasing the thickness of the fin portion. Hold in surface contact. Thereby, according to this invention, the fitting force of the plate-shaped object with respect to the glazing channel with which the collar was equipped becomes smaller than before, and the drawing-out force of the plate-shaped body with respect to the said glazing channel becomes higher than before.

  In other words, when the plate-like body is fitted into the heel, the contact surface of the glazing channel with the plate-like body receives a force in the direction of compression toward the base end portion of the glazing channel, and the repulsive force strengthens the plate-like body. Hold on. On the other hand, the fin portion of the conventional glazing channel has an arc-shaped contact portion, so that when the plate-like body is fitted into the flange, the fin portion is pushed by the plate-like body and bent into the arc shape. It ’s just that. Therefore, the conventional glazing channel does not receive the force in the compressing direction, and the force applied from the fin portion to the plate-like body is only the elastic restoring force of the fin portion. For this reason, the pulling force by the glazing channel of the present invention is larger than that of the conventional glazing channel. Therefore, according to the glazing channel of the present invention, the assembling workability of the sash is improved and the plate-like body holding force is improved as compared with the conventional case.

  In addition, the glazing channel of the present invention has an advantage that the holding power of the glazing channel with respect to the plate-like body does not decrease due to the effect of the surface contact even when the heel is twisted.

  According to the present invention, the planar portion comes into surface contact with the plate-like body so that a pulling-out load becomes larger than a fitting load of the plate-like body with respect to the glazing channel provided in the heel.

  According to the present invention, the fitting force is evaluated as the fitting load, and the pulling force is evaluated as a pulling load. In this case, the flat portion of the glazing channel is in surface contact with the plate-like body so that the pulling load is larger than the fitting load.

  According to the present invention, in the surface contact portion between the flat portion of the glazing channel and the plate-like body, the length of the surface contact portion in a plane perpendicular to the longitudinal direction of the glazing channel is 2 mm or more. It is desirable. If the length of the contact portion is 2 mm or more, a good plate-like body holding force can be obtained.

  The glazing channel of the present invention is preferably made of resin or rubber having a Shore A hardness of 50 to 90 degrees. If the Shore A hardness of the glazing channel is less than 50 degrees, it is too soft to obtain a sufficient plate-like body holding force, and if the Shore A hardness exceeds 90 degrees, it becomes too hard and the fitting force increases. This is because the assembly workability of the sash is hindered.

  The back surface of the contact surface of the glazing channel of the present invention is preferably provided with a notch at a position facing the stepped portion. According to the present invention, since the glazing channel is easily bent by providing the notch, the assembly workability of the sash is further improved.

  It is preferable that a reinforcing member harder than the glazing channel is provided on the back surface of the contact surface of the glazing channel of the present invention. According to the present invention, the soft glazing channel can be reinforced by the hard reinforcing member, and creep of the glazing channel can be suppressed.

  In order to achieve the above-mentioned object, the present invention provides a glazed channel-attached kite characterized in that the glazing channel of the present invention and the kite are integrated. The sash can be assembled simply by fitting the plate-like body into the glazed channel-equipped bag of the present invention.

  The bag of the present invention is preferably made of resin or metal. As long as it can be integrated with the glazing channel of the present invention, the material of the bag may be made of resin or metal. Further, the glazing channel (fin portion) may be integrated with the ridge, or may be integrated by adhering the fin portion to the inner wall of the ridge. Further, a glazing channel having a portion (wall surface, bottom surface, etc.) other than the fin portion may be integrated with the ridge. In this case, the configuration in which the base end portion of the fin portion is fixed to the inner wall surface of the flange is that the base end portion of the fin portion is indirectly fixed to the inner wall surface of the flange through a portion other than the fin portion of the glazing channel. It means to do.

  In order to achieve the above object, the present invention provides a sash characterized in that a plate-like body is attached to the glazed channel-equipped saddle of the present invention.

  According to the sash of this invention, the assembly workability | operativity of a sash and a plate-shaped body holding force improve.

  The plate-like body of the present invention is not limited to a glass plate such as a single plate glass plate, a multi-layer glass, and a laminated glass, but also includes resin and wood panel materials.

  Further, the glazing channel of the present invention is not limited to the glazing channel integrated with the bag, and may be a glazing channel separate from the bag. In the case of a glazing channel separate from the heel, the fin portion corresponds to the glazing channel of the present invention.

  According to the glazing channel, the scissors with glazing channel and the sash of the present invention, the assembly workability of the sash is improved and the plate-like body holding force is improved.

  FIG. 1 is a conceptual diagram showing the configuration of the glazing channel 1 of the present invention, and FIG. 2 is a diagram of a sash 4 in which the edge of a plate-like body 3 is fitted in a ridge 2 having the glazing channel 1 of FIG. It is sectional drawing.

  As shown in these drawings, the glazing channel 1 of the present invention is formed on the opposing inner wall surfaces 2A and 2A of the opposite-side ridge 2 having an insertion groove into which the edge of the plate-like body 3 is inserted. The base end portion 1A is fixed to the inner wall surface 2A, and the distal end portion 1B is disposed so as to face the bottom wall 2B of the flange 2. The glazing channel 1 includes a flat portion 1 </ b> C that makes surface contact with the plate-like body 3. That is, the planar portion 1C is in surface contact with the plate-like body 3 so that the pulling load becomes larger than the fitting load of the plate-like body 3 with respect to the glazing channel 1 provided in the flange 2. Further, in the surface contact portion formed by the flat surface portion 1C, the length L of the surface contact portion on the surface perpendicular to the longitudinal direction of the glazing channel 1 is set to 2 mm or more in order to increase the plate-like body holding force. .

  Next, a preferred embodiment of the glazing channel, the glazed channel-attached bag and the sash according to the embodiment will be described.

  FIG. 3 is a cross-sectional view of the ridge 12 in which the glazing channels 10 and 10 of the embodiment are integrated. The glazing channels 10 and 10 are arranged along the longitudinal direction of the ridge 12.

  FIG. 4 is a cross-sectional view of a sash 16 in which a thin glass plate (plate-like body) 14 (for example, a thickness of 3 mm) 14 is fitted in the ridge 12 shown in FIG. 3, and FIG. 4 is a cross-sectional view of a sash 20 in which a glass plate 18 having a thickness (for example, a thickness of 5 mm) thicker than that of the glass plate 14 of FIG. 4 is fitted, and FIG. 6 is a cross-sectional view of FIG. 12 is a cross-sectional view of a sash 24 in which a glass plate 22 having a thickness (for example, a thickness of 6.8 mm) thicker than that of the glass plate 18 of FIG. That is, the glazing channels 10, 10 and the ridge 12 of the embodiment can correspond to three glass plates 14, 18, 22 having different thicknesses.

  In addition, although the glazing 12 with which the glazing channel 10 was integrated is illustrated in embodiment, the glazing channel 10 and the heel 12 may be a separate form. The glazing channel is preferably made of a resin having a Shore A hardness of 50 to 90 degrees (for example, vinyl chloride resin or urethane resin) or rubber. If the Shore A hardness is less than 50 degrees, it is too soft to obtain a sufficient holding force for the glass plates 14, 18 and 22, and if the Shore A hardness exceeds 90 degrees, the glass becomes too hard. This is because it is difficult to fit the plates 14, 18 and 22 into the flange 12. Moreover, it is preferable that the collar 12 is resin or metal. That is, the ridge 12 may be made of any material that can be integrated with the glazing channel 10 and can obtain the strength of the ridge 12.

  Hereinafter, the glazing channel 10 configured to be compatible with the three glass plates 14, 18, and 22 will be described.

  As shown in FIGS. 3 to 6, the flange 12 is configured to have a concave cross-sectional shape with an insertion groove into which the edge of the glass plate 14, 18, 22 is inserted. The glazing channel 10 is integrated with the wall surfaces 26 and 26. That is, the base end portion 10 </ b> A of the glazing channel 10 is fixed to the inner wall surface 26, and the distal end portion 10 </ b> B is disposed so as to face the bottom wall 28 of the flange 12. And the plane part which is the contact surface 30 (refer FIG. 3) with the glass plates 14, 18, and 22 of the glazing channel 10 is comprised in the step shape which has several step parts toward the front-end | tip part 10B from 10 A of base end parts. Has been.

  That is, in the glazing channel 10 of the embodiment, the contact surface 30 with the glass plates 14, 18, and 22 is configured in a three-step shape including the tread surfaces 32 and 34 and the kick surfaces 36, 38, and 40. Therefore, the thickness of the glass plates 14, 18, and 22 can be followed.

  As shown in FIG. 4, when the edge of the glass plate 14 is fitted into the flange 12, the glazing channels 10, 10 are elastically deformed so that the gap between the glazing channels 10, 10 is expanded. The kick surface 36 is brought into contact. Further, as shown in FIG. 5, when the edge of the glass plate 18 is fitted into the ridge 12, the glazing channels 10 and 10 are elastically deformed so that the gap between the glazing channels 10 and 10 is expanded, whereby the glass plate 18, the tread surface 32 and the kick surface 38 are brought into contact with each other. Furthermore, as shown in FIG. 6, when the edge of the glass plate 22 is fitted into the flange 12, the glazing channels 10, 10 are further elastically deformed so that the gap between the glazing channels 10, 10 is more widely spread. The tread surface 34 and the kick surfaces 38 and 40 are in contact with the glass plate 22. As described above, the glass plates 14, 18, and 22 are held by the ridge 12 in a state of surface contact with the glazing channels 10 and 10. Reference numeral 42 denotes a setting block on which the end surfaces of the glass plates 14, 18 and 22 are placed.

  As described above, in the glazing channel 10 of the embodiment, the contact surfaces 30 with the glass plates 14, 18, and 22 are formed in a stepped shape, and therefore the glass plates 14, 18, and 22 are treads according to their thicknesses. It is held in surface contact with the surfaces 32, 34 or the kick surfaces 36, 38, 40. Further, the contact form between the contact surface 30 of the glazing channel 10 and the glass plates 14, 18, 22 is not a conventional line contact but a surface contact, so that the glass plates 14, 18, 22 are held on the ridge 12 with a good holding force. it can.

  Further, the glazing channel 10 of the embodiment has an advantage that the holding force of the glazing channel 10 with respect to the glass plates 14, 18, and 22 does not decrease due to the action of the surface contact even when the ridge 12 is twisted due to wind pressure or the like. There is.

  Furthermore, in the glazing channel 10 of the embodiment, the glass plate 14, 18, 22 from the ridge 12 rather than the force (fitting force) to fit the glass plates 14, 18, 22 into the ridge 12 by the stepped configuration. Since the force for pulling out (the pulling force) becomes larger, the assembling workability of the sashes 16, 20, and 24 and the holding force of the glass plates 14, 18, and 22 are improved.

  That is, since the contact surface 30 with the glass plates 14, 18, and 22 is configured in a step shape, the glazing channel 10 of the embodiment has a glass plate when the glass plates 14, 18, and 22 are fitted into the ridges 12. 14, 18, 22 contact surfaces (tread surfaces 32, 34, kick surfaces 36, 38, 40) receive a force in the direction of compression toward the base end portion 10 </ b> A of the glazing channel 10, and the repulsive force causes glass to The plates 14, 18, and 22 are firmly held. On the other hand, the fin portion of the conventional glazing channel has an arc-shaped contact surface, so when the glass plate is incorporated, the fin portion is pushed by the glass plate and only bends in the arc shape. . Therefore, the conventional glazing channel does not receive the force in the compressing direction, and the force applied from the fin portion to the glass plate is only the elastic restoring force of the fin portion. For this reason, the pulling force by the glazing channel 10 of the embodiment is larger than that of the conventional glazing channel.

  In addition, in the conventional glazing channel, in order to obtain a large elastic restoring force, the gap (interval) between the opposing fin portions has been reduced as much as possible, or the thickness of the fin portions has been increased. For this reason, the fitting force is larger than necessary. On the other hand, since the glazing channel 10 of the embodiment is configured to hold the glass plates 14, 18, and 22 in surface contact with a stepped surface, it is necessary to make the gap between the glazing channels 10 and 10 smaller than necessary. There is no need to make the glazing channel 10 thicker than necessary. For this reason, the fitting force is smaller than that of the conventional glazing channel.

  In the glazing channel 10 of the embodiment, the contact surface 30 is formed in a three-step shape, but this is not restrictive.

  Further, the glazing channel 10 of the embodiment is manufactured so that the thickness decreases from the base end portion 10A toward the tip end portion 10B. When the thickness of the glazing channel is the same from the base end to the tip, the fitting force increases as the thickness of the glass plate increases, but the glazing channel 10 of the embodiment is Coupled with the step-like shape, the fitting force can be made substantially uniform regardless of the thickness of the glass plates 14, 18, 22.

  On the other hand, the sash 16, 20, 24 can be assembled only by fitting the edges of the glass plates 14, 18, 22 into the heel 12 according to the heel 12 in which the glazing channel 10 of the embodiment is integrated. Therefore, the assembling workability of the sashes 16, 20, and 24 is improved.

  FIG. 7 is a cross-sectional view of the ridge 12 showing a first modification of the glazing channel 10.

  The back surface of the contact surface 30 of the glazing channel 10 shown in the figure is provided with a notch 44 at a position facing the boundary between the tread surface 32 and the kick surface 36, which is a step portion of the contact surface 30. A notch 46 is provided at a position facing the boundary between the surface 34 and the kick surface 40.

  According to the glazing channel 10 shown in FIG. 7, by providing the notches 44 and 46, the glazing channel 10 is easily bent, so that the fitting force can be reduced, and the sash 16, 20, and 24 can be assembled more easily. Further improvement.

  FIG. 8 is a cross-sectional view of the ridge 12 showing a second modification of the glazing channel 10.

  On the back surface of the contact surface 30 of the glazing channel 10 shown in the figure, a plate-like reinforcing member 48 that is harder than the glazing channel 10 is provided. Accordingly, the soft glazing channel 10 can be reinforced by the hard reinforcing member 48 and creep of the glazing channel 10 can be suppressed. It is preferable in manufacturing that the reinforcing member 48 is made of resin and is integrally formed on the back surface of the glazing channel 10 by extrusion molding together with the extrusion molding of the glazing channel 10.

  FIG. 9 is a cross-sectional view of the ridge 12 showing a third modification of the glazing channel 10.

  The glazing channel 10 shown in the figure is obtained by adding the reinforcing member 48 shown in FIG. 8 to the glazing channel 10 with the notches 44 and 46 shown in FIG. Further, notches 50 and 52 are provided at positions facing the notches 44 and 46 of the reinforcing member 48. That is, the glazing channel 10 shown in FIG. 9 has the effects of the glazing channels 10 and 10 shown in FIGS.

[Comparison experiment of mating load and pull-out load]
The following comparative experiment is to determine the index of the fitting force and the pulling force (plate body holding force) by evaluating the fitting force as the fitting load and evaluating the pulling force as the pulling load. is there. In addition, as an evaluation device, a glazing channel evaluation device disclosed in Japanese Patent Application Laid-Open No. 2009-156616 was used, and the fitting force and the pulling force were simply measured. Furthermore, all the sash samples used have a total length of 300 mm. Further, the Shore A hardness of the glazing channel 10 of the example was 70 degrees.

  In addition, the thickness of a glass plate means the thickness prescribed | regulated to JISR3202-1996. The following maximum fitting load and maximum pull-out load are average values of five samples each.

〔Example〕
In the sashes 16, 20, and 24 of the embodiment shown in FIGS. 4, 5, and 6, the maximum fitting load and the maximum pull-out load of the glass plates 14, 18, and 22 with respect to the ridge 12 having the glazing channel 10 are set. It was measured. The results are shown in Table 1.

  In all three examples, it was confirmed that the maximum pulling load exceeded the maximum fitting load.

  In the glass plate 14 of FIG. 4 having a thickness of 3 mm shown in Example 1, the assembling workability of the sash 16 is greatly improved because the maximum fitting load is as small as 11N. Further, since the maximum pulling load was as large as 95 N, the holding power of the glass plate 14 was also good. In addition, the length L of the surface contact portion with the glass plate 14 in the plane perpendicular to the longitudinal direction of the glazing channel 10 was 2 mm or more.

  In the glass plate 18 of FIG. 5 having a thickness of 5 mm shown in Example 2, the maximum fitting load is 25 N, and the maximum fitting load is larger than that of the glass plate 14 having a thickness of 3 mm. It did not hinder the assembly workability. Further, the maximum pulling load is substantially halved compared to the glass plate 14 having a thickness of 3 mm, but it does not hinder the holding force of the glass plate 14. Further, the length L of the surface contact portion with the glass plate 18 on the surface in the direction orthogonal to the longitudinal direction of the glazing channel 10 was 2 mm or more.

  In the glass plate 22 of FIG. 6 having a thickness of 6.8 mm shown in Example 3, the maximum pulling load is considerably large as 132 N, and thus the holding force of the glass plate 22 was good. Moreover, although the maximum fitting load was quite large as 97N, it was a value small enough compared with the maximum extraction load (132N). In addition, the length L of the surface contact portion with the glass plate 22 in the plane perpendicular to the longitudinal direction of the glazing channel 10 was 2 mm or more.

[Comparative Example]
4, 5, and 6 of the sashes 16, 20, and 24 of the embodiment shown in FIG. 6, and the fitting load of the glass plate G in the ridge 62 having the conventional glazing channel 60 shown in FIG. 10, and The pulling load was measured. In this ridge 62, when the thickness of the glass plate was set to 3, 5, and 6.8 mm, glazing channels for the respective thicknesses were required. Moreover, also in the glass plate of each plate | board thickness, the length L of the contact part with the glass plate in the surface of the direction orthogonal to the longitudinal direction of a glazing channel was less than 2 mm, and was almost line contact. Table 2 shows the results of the fitting load and the drawing load.

  As a result of the above comparative experiment, according to the sashes of Examples 1 to 3, the size of the fitting load with respect to the pull-out load was significantly reduced as compared with the sashes of Comparative Examples 1 to 3. Since the pull-out load was significantly increased, the holding power of the glass plate was improved.

  The maximum fitting load is preferably about 10 to 100 N from the viewpoint of improving the assembly workability of the sash, and the maximum pulling load is preferably 45 N or more from the viewpoint of improving the plate-like body holding force.
