Description

  The present invention relates to a fixture and a glass plate structure.

  For example, when a glass plate is fixed to a member to be fixed, such as a case where a window glass is attached to a window frame of an automobile, a fixture may be used to perform positioning, temporary fixing, etc. of the glass plate. . As an example of a fixture used in such a scene, for example, Patent Document 1 proposes a clip for temporarily fixing a glass plate.

  The clip for temporarily fixing a glass plate proposed in Patent Document 1 is provided on a member to be fixed, extending from an adhesive plate portion bonded to the glass plate by an adhesive, and an outer surface of the adhesive plate portion. And a locking leg portion that is inserted into the opening (mounting hole) and locked. A frame-shaped recess having a predetermined depth is formed along the periphery on the bonding surface of the bonding plate portion, and an adhesive is applied to the inside of the frame-shaped recess. Therefore, when the clip for temporarily fixing the glass plate is bonded to the glass plate, the adhesive that is pushed out and spreads into the glass plate enters the frame-shaped recess, thereby preventing the adhesive from protruding from the locking leg. Can do.

JP 2010-014147 A

  In the clip for temporarily fixing a glass plate proposed in Patent Document 1, a frame-shaped recess is provided in an adhesive plate portion bonded to the glass plate. Therefore, if a sufficient depth is secured to prevent the adhesive from protruding in the frame-shaped recess, there is a problem that the thickness of the adhesive plate portion increases. That is, when the plate thickness of the adhesive plate portion is not sufficient, it is difficult to form a frame-shaped recess that prevents the adhesive from protruding, and the degree of freedom in designing the glass plate temporary fixing clip is low. was there.

  Moreover, in the clip for glass plate temporary fixing proposed by patent document 1, the latching leg part is comprised by the hollow shape, and the said latching leg part is comprised so that elastic deformation is possible. This hollow portion is formed when the glass plate temporary fixing clip is integrally formed, and generally opens to the distal end side of the locking leg portion or the adhesive plate portion side.

  Here, in patent document 1, the hollow part of this latching leg part is opened to the front end side of the latching leg part. For this reason, it is difficult to make the tip of the locking leg thin, and when the opening provided in the member to be fixed is small, the locking leg of the glass plate temporary fixing clip is placed in the opening. It becomes difficult to introduce. As a result, it becomes difficult to attach the glass plate to the fixed member.

  On the other hand, a fixture 9 as exemplified in FIG. 15 is also used as a fixture used in fixing a glass plate to a member to be fixed. FIG. 15 illustrates a fixture 9 according to a conventional example. 15 includes a base 91 having an upper surface 911 directed toward the member to be fixed and a lower surface 912 bonded to the glass plate 8 by the adhesive 94, and an opening provided in the member to be fixed. And a pillar portion 92 to be inserted (not shown).

  The column portion 92 inserted into the opening of the fixed member is formed in a cylindrical shape by the hollow portion 921, and a locking piece 93 that can be elastically deformed so as to enter the hollow portion 921 is provided in the column portion 92. It has been. Therefore, when the column portion 92 is inserted into the opening portion of the fixed member, the locking piece 93 is elastically deformed in the direction of entering the hollow portion 921, thereby moving the column portion 92 to the back side of the opening portion. Can be inserted. And after inserting the pillar part 92 in the opening part of a to-be-fixed member, the latching piece 93 returns to the original position, and the level | step difference 931 of the latching piece 93 latches to the opening part periphery of a to-be-fixed member. That is, the glass plate 8 can be fixed to the fixed member.

  Here, in the fixture 9, the hollow portion 921 is open to the lower surface 912 side. That is, the opening region 913 formed when the fixture 9 is integrally formed is disposed on the lower surface 912 side of the base 91. Therefore, no opening is formed on the tip end side of the column part 92, and the tip of the column part 92 can be made thin. Thereby, the column part 92 can be easily introduced into the opening provided in the fixed member.

  However, the inventor of the present invention has found that such a fixture 9 has the following problems. That is, in the fixture 9, an opening region 913 exists on the lower surface 912 to which the adhesive 94 is applied. Therefore, the adhesive 94 applied to the lower surface 912 spreads by the force in the arrow S direction applied when the fixture 9 is bonded to the glass plate 8, and the adhesive 94 enters the hollow portion 921 from the opening region 913. End up.

  If a large amount of the adhesive 94 enters the hollow portion 921, the adhesive 94 reaches the locking piece 93, and the locking piece 93 may be solidified by the adhesive 94. If it does so, it will become difficult to elastically deform the latching piece 93, and it will become difficult to insert the pillar part 92 in the opening part of a to-be-fixed member. Thus, the inventors of the present invention have found that there is a possibility that an attachment failure that the glass plate cannot be fixed to the member to be fixed may occur.

  The inventors of the present invention have also found the following problems. That is, when the fixture 9 is bonded to the curved glass plate 8, a larger force is applied to the fixture 9 in the direction of the arrow S than when the fixture 9 is bonded to a flat glass plate. As a result, the base 91 of the fixture 9 is elastically deformed to match the shape of the glass plate 8.

  However, the adhesive 94 around the opening region 913 penetrates into the hollow portion 921 or spreads to other regions due to a large force in the direction of arrow S applied when the fixture 9 is attached to the glass plate 8. Therefore, the amount of the adhesive 94 that acts to adhere the fixture 9 (lower surface 912) and the glass plate 8 around the opening region 913 is reduced.

  In addition, since the adhesive 94 does not harden immediately, when the force in the arrow S direction is lost, the base 91 tries to return to the original shape and is slightly separated from the glass plate 8. Then, in the lower surface 912, particularly in the opening region 913, the amount of the adhesive 94 that acts to adhere the fixture 9 (lower surface 912) and the glass plate 8 is further reduced, resulting in a region having a low adhesive strength. End up.

  Here, the opening region 913 is formed at a position corresponding to the hollow portion 921. That is, the opening region 913 is basically formed immediately below the pillar portion 92. Since the column portion 92 is a portion to be inserted into the opening of the fixed member, the load of the glass 8 is supported by the column portion 92 when the glass plate 8 is fixed to the fixed member. That is, a relatively large load can act on the periphery of the opening region 913 that is directly below the column portion 92.

  However, in the conventional fixture 9, the adhesive strength is reduced around the opening region 913 due to the above-described reason. Therefore, the fixing tool 9 cannot support the load of the glass plate 8, and after attaching the glass plate 8 to a to-be-fixed member, there exists a problem that the attachment defect that the fixing tool 9 will come off may arise. The inventors of the present invention have found.

  In one aspect, the present invention has been made in view of these problems, and an object thereof is to provide a fixture that can satisfactorily fix a glass plate to a member to be fixed with a simple configuration.

  The present invention employs the following configuration in order to solve the above-described problems.

  That is, a fixture according to one aspect of the present invention is a fixture for fixing a glass plate to a member to be fixed, the first surface directed toward the member to be fixed, and the first surface. A base portion having a second surface facing and bonded to the glass plate by an adhesive; a column portion extending from the first surface so as to be inserted and locked into an opening provided in the fixed member; And one or a plurality of protrusions disposed around the opening region of the hollow portion on the two surfaces.

  In the fixture according to the configuration, when the fixture is bonded to the glass plate, the distance between the second surface of the fixture and the surface of the glass plate may be increased by the height of one or more protrusions. it can. Therefore, the second surface of the fixture is prevented from being pressed too much against the glass plate, and the height between one or more protrusions is between the second surface of the fixture and the surface of the glass plate. The distance can be kept moderate. Thereby, it is possible to prevent the adhesive applied to the second surface from being pushed out and spread too much, and to retain an appropriate amount of the adhesive between the second surface and the glass plate. That is, the fixing tool can be satisfactorily bonded to the glass plate with an appropriate amount of adhesive, and it is possible to prevent a mounting failure in which the fixing tool comes off after the glass plate is attached to the fixed member. it can.

  Moreover, the 1 or several protrusion part for preventing the protrusion of such an adhesive agent can be provided suitably, without depending on the shape of the base bonded to a glass plate. That is, it is possible to prevent the adhesive from protruding as described above with a very simple configuration in which one or a plurality of protrusions are provided on the adhesive surface (second surface) of the base.

  Therefore, according to the fixture concerning the said structure, a glass plate can be favorably fixed to a to-be-fixed member with a simple structure. The fixing of the glass plate by the fixture may be performed for reasons such as positioning the glass plate in order to temporarily fix (temporarily fix) the glass plate to the member to be fixed. Further, the member to be fixed is not particularly limited as long as the member can fix the glass plate. The member to be fixed is, for example, a vehicle body (window frame) of a vehicle such as an automobile. When the member to be fixed is an automobile body, the glass plate is, for example, a window glass such as a windshield of a vehicle.

  Moreover, as another form of the fixture according to the one side surface, the pillar portion may be formed in a cylindrical shape by a hollow portion opened to the second surface side. And when inserting the said column part in the opening part of the said to-be-fixed member, the said column part is elastically deformed in the direction penetrate | invaded into the said hollow part, and the said column part is inserted in the opening part of the said to-be-fixed member After that, a locking piece configured to lock to the periphery of the opening may be provided.

  In the fixture according to the configuration, the opening region formed by the hollow portion of the column portion is formed on the second surface side to which the adhesive is applied, and one or a plurality of protrusions are disposed on the second surface. Therefore, when the second surface of the base is bonded to the glass plate, the flow of the adhesive that is pushed and spread on the second surface by the one or more protrusions is suppressed, and the adhesive flows into the vicinity of the opening region. It can be reduced or prevented. Thereby, it is possible to prevent a large amount of adhesive from entering the hollow portion from the opening region. That is, it is possible to prevent a mounting failure caused by the locking piece being hardened by the adhesive. Therefore, according to the fixture according to this configuration, it is possible to satisfactorily fix the glass plate to the member to be fixed despite the presence of the opening region on the bonding surface side.

  As another form of the fixture according to the one aspect, the one or the plurality of protrusions may be arranged around an opening region formed by the hollow portion on the second surface. According to this configuration, one or a plurality of protrusions are arranged around the opening region. For this reason, when the second surface of the base is bonded to the glass plate, the one or more protrusions are made to act positively to prevent the adhesive spread out on the second surface from flowing into the vicinity of the opening region. Can stop. That is, according to this configuration, it is possible to efficiently reduce or prevent the adhesive from flowing into the vicinity of the opening region. Therefore, according to the fixture concerning the said structure, a glass plate can be favorably fixed to a to-be-fixed member.

  Moreover, as another form of the fixture according to the one side surface, the pair of protrusions may be arranged to face each other across the opening region. According to this configuration, the movement of the adhesive in the direction in which the pair of protrusions are arranged can be blocked by the pair of protrusions, and thereby a large amount of adhesive enters the hollow portion from the opening region. Can be prevented. Therefore, according to the fixture according to the configuration, the glass plate can be satisfactorily fixed to the member to be fixed.

  As another form of the fixture according to the one aspect, the protrusion may be configured to surround the opening region. According to this configuration, it is possible to satisfactorily prevent a large amount of adhesive from flowing into the opening region from a region other than the opening region, and thereby a large amount of adhesive enters the hollow portion from the opening region. Can be prevented. Therefore, according to the fixture according to the configuration, the glass plate can be satisfactorily fixed to the member to be fixed.

  Further, a glass plate structure according to one aspect of the present invention is a glass plate and a fixture bonded to the glass plate for fixing the glass plate to a fixed member. A fixture. According to the said structure, a glass plate structure provided with the fixing tool which can fix a glass plate favorably to a to-be-fixed member can be provided, although an opening area | region exists in the adhesion surface side.

  Further, a glass plate structure according to one aspect of the present invention is a glass plate and a fixture bonded to the glass plate for fixing the glass plate to a fixed member. A fixture. Then, when the second surface of the fixture is bonded to the glass plate, an adhesive is applied to the second surface of the fixture including the opening region.

  According to the said structure, when bonding a fixing tool to a glass plate, it reduces that the adhesive agent apply | coated other than near the opening area | region flows into an opening area | region by the 1 or several protrusion part provided in the opening area | region vicinity. Or it can be prevented. Therefore, even if an adhesive is applied including the opening region, it is possible to prevent a fixing device from being attached poorly due to a large amount of adhesive entering the hollow portion from the opening region.

  Further, according to this configuration, when the fixing tool is bonded to the glass plate, the adhesive applied to the vicinity of the opening area flows out to the other area by one or a plurality of protrusions provided in the vicinity of the opening area. Can be reduced or prevented. That is, a certain amount of adhesive can be retained in the region immediately below the pillar. Therefore, according to the said structure, it prevents that the adhesive strength of the area | region where the load of a glass plate tends to act is reduced, and the attachment defect that a fixing tool will come off after attaching a glass plate to a to-be-fixed member arises. Can be prevented.

  That is, according to the said structure, a moderate amount of adhesive agents can remain in the opening area vicinity, and this moderate amount of adhesive agents can be made to act on adhesion | attachment with the 2nd surface of a base, and a glass plate. Therefore, in the glass plate structure according to the configuration, the fixture can be appropriately bonded to the glass plate, and the glass plate can be favorably fixed to the member to be fixed by the fixture.

  As another form of the glass plate structure according to the one aspect, the glass plate is curved, and the base of the fixture is formed flat with an elastically deformable material, and the second surface of the fixture. May be pressure-bonded to the curved surface of the glass plate. According to the said structure, the glass plate which adhere | attaches a fixing tool is curving, and the base part of a fixing tool is formed in the flat shape which can be elastically deformed. Therefore, in this case, a larger force can act on the fixture when the fixture is bonded to the glass plate than when the glass plate is flat.

  However, according to the said structure, the 1 or several protrusion part is provided in the periphery of the opening area | region of the 2nd surface of a fixing tool. Therefore, even if the second surface of the fixture is pressed against the surface of the glass plate by a relatively large force, the movement of the adhesive applied to the second surface is blocked by the one or more protrusions, and the opening It is possible to prevent a large amount of adhesive from entering the hollow portion from the region.

  Moreover, the space | interval between the 2nd surface of a fixing tool and the surface of a glass plate can be vacated by the height of a projection part. For this reason, it is possible to prevent the second surface of the fixture from being excessively pressure-bonded to the surface of the glass plate, and to retain a certain amount of adhesive between the second surface of the fixture and the glass plate. As a result, after the second surface of the fixture is pressure-bonded to the surface of the glass plate, the base portion tries to return to the original shape until the adhesive is solidified, and the second surface of the fixture is the surface of the glass plate. Even if it is slightly separated from the above, it is possible to maintain the state where the second surface of the fixture is adhered to the surface of the glass plate by a certain amount of adhesive. Therefore, according to the said structure, it can prevent that the adhesive strength of a fixing tool and a glass plate reduces.

  Moreover, as another form of the glass plate structure according to the one side surface, both end portions of the second surface of the fixture may be bonded to the glass plate by a double-sided tape. According to the said structure, until an adhesive agent hardens | cures, fixing a fixing tool and a glass plate with a double-sided tape, and preventing that the 2nd surface of a fixing tool leaves | separates from the surface of a glass plate. it can. In addition, the distance between the second surface of the fixture and the surface of the glass plate can be appropriately maintained depending on the thickness of the double-sided tape. Thereby, the thickness of an adhesive bond layer can be ensured appropriately and the adhesive strength of a fixing tool and a glass plate can be improved. Therefore, since the fixture can be firmly bonded to the glass plate, the glass plate can be satisfactorily fixed to the member to be fixed according to the fixture according to the configuration.

  ADVANTAGE OF THE INVENTION According to this invention, although it has an opening area | region in the adhesion surface side, the fixing tool which can fix a glass plate favorably to a to-be-fixed member can be provided.

Hereinafter, each of these components will be described.

<Glass plate>
First, the glass plate 2 will be described. A glass plate 2 according to this embodiment illustrated in FIG. 1 is used as a window glass of an automobile and is configured in a shape corresponding to the window frame of the automobile to be attached. In the present embodiment, the glass plate 2 has a substantially trapezoidal shape in a plan view, and in a side view, the peripheral surface is such that the front side surface of FIG. 1 is concave and the back side surface is convex. It is formed in a curved shape from the center to the center. The curved glass plate 2 can be formed by, for example, a self-weight bending method, a press molding method, or the like.

  Such a glass plate 2 can have various configurations according to the embodiment. Further, a known glass plate for automobiles can be used for the glass plate 2. For example, the glass plate 2 may be heat ray absorbing glass, general clear glass or green glass, or UV green glass. However, such a glass plate 2 needs to realize visible light transmittance in accordance with the safety standards of the country where the automobile is used. For example, the solar radiation absorptivity and visible light transmittance can be adjusted to satisfy safety standards. Below, an example of a composition of clear glass and an example of a heat ray absorption glass composition are shown.

Al ₂ O ₃ : 0.6 to 2.4% by mass
CaO: 7 to 12% by mass
MgO: 1.0 to 4.5 mass%
R ₂ O: 13 to 15% by mass (R is an alkali metal)
Fe total iron oxide in terms of _{2 O 3 (T-Fe 2} O 3): 0.08~0.14 wt%

(Heat ray absorbing glass)
The composition of the heat-absorbing glass, for example, based on the composition of the clear glass, the proportion of the total iron oxide in terms of _{Fe 2 O 3 (T-Fe} 2 O 3) and 0.4 to 1.3 wt%, CeO ₂ ratio as 0-2 mass%, the proportion of TiO ₂ and 0 to 0.5 wt%, framework component of the glass (mainly, SiO ₂ and Al ₂ O ₃₎ to T-Fe ₂ O _3, CeO _The composition can be reduced by an increase of ₂ and TiO ₂ .

  In addition, the kind of glass plate 2 is not restricted to clear glass or heat ray absorption glass, According to embodiment, it can select suitably. For example, the glass plate 2 may be an acrylic or polycarbonate resin window.

  Moreover, the thickness of the glass plate 2 which concerns on this embodiment does not need to be specifically limited. However, from the viewpoint of weight reduction, the thickness of the glass plate 2 may be set in the range of 2.2 to 5.1 mm, or may be set in the range of 2.4 to 3.8 mm. You may set in the range of 7-3.2 mm. Furthermore, the thickness of the glass plate 2 may be set to be 3.1 mm or less.

<Fixing tool>

FIG. 3 is a right side view schematically illustrating the fixture 1 according to the present embodiment. FIG. 4 is a bottom view schematically illustrating the fixture 1 according to this embodiment. FIG. 5 schematically illustrates a cross section taken along line AA of FIG. FIG. 6 schematically illustrates a cross section taken along line BB in FIG. For convenience of explanation, the up and down direction in FIG. 2 is referred to as “up and down”, the left and right direction in FIG. 2 is referred to as “left and right”, and the direction perpendicular to the paper surface in FIG.

  As illustrated in FIGS. 2 and 3, the fixture 1 according to this embodiment includes a rectangular parallelepiped base portion 11 having an upper surface 111 and a lower surface 112 facing the upper surface 111, and an upper side from the upper surface 111 of the base portion 11. And a cylindrical column portion 12 extending in the direction. The fixture 1 is used to temporarily fix the glass plate 2 to the vehicle body.

  The base 11 of the fixture 1 is formed in a flat shape. Specifically, the base 11 extends in the left-right direction, and has a flat and horizontally long shape. The length of the base 11 in the left-right direction may be appropriately set to such an extent that the fixture 1 can be sufficiently bonded to the glass plate 2. For example, the length in the left-right direction of the base 11 may be set to about 70 mm.

  The upper surface 111 of the base 11 is a surface facing the fixed member (vehicle body) and corresponds to the first surface of the present invention. On the other hand, the lower surface 112 of the base 11 is a surface bonded to the glass plate 2 by an adhesive as will be described later, and corresponds to the second surface of the present invention. 2 illustrates a state in which the fixture 1 is placed with the lower surface 112 bonded to the glass plate 2 facing downward. That is, FIG. 2 illustrates the state of the fixture 1 as viewed from above in FIG.

  On the other hand, the column portion 12 of the fixture 1 extends upward from the upper surface 111 of the base portion 11 so as to be inserted into an opening provided in the vehicle body described later. However, the extending direction of the column portion 12 is not limited to such an example, and may be appropriately selected according to the embodiment as long as the column portion 12 can be inserted into the opening of the vehicle body. Moreover, the height (length in the vertical direction) of the column portion 12 may be appropriately set according to the embodiment as long as the column portion 12 can be inserted into the opening of the fixed member and locked. For example, the height of the column part 12 may be set to about 11 mm.

  The column part 12 has a cylindrical hollow part 121, and is formed in a cylindrical shape by the hollow part 121. Further, as illustrated in FIG. 2, the pillar portion 12 is provided with a rectangular opening groove 122 communicating with the hollow portion 121 from the front, and the locking piece 13 is provided in the opening groove 122. Is provided. The opening groove 122 extends in the vertical direction, and the locking piece 13 is connected to the column portion 12 at the upper end of the opening groove 122. The locking piece 13 extends along the opening groove 122 downward from the upper end of the opening groove 122. Accordingly, the locking piece 13 is configured to be elastically deformable in the direction of entering the hollow portion 121.

  Specifically, the locking piece 13 is configured as follows. That is, as illustrated in FIGS. 3 and 6, the locking piece 13 according to the present embodiment extends from the protruding portion 132 and a triangular protruding portion 132 that is connected to the column portion 12 at the upper end of the opening groove 122. A rectangular extending portion 133.

  In the vicinity of the boundary between the protruding portion 132 and the extending portion 133 in the vertical direction, the protruding portion 132 is wider than the extending portion 133 (the length in the left-right direction in FIGS. 3 and 6). Therefore, a step 131 due to the lower surface of the projecting portion 132 occurs at the boundary between the projecting portion 132 and the extending portion 133 in the vertical direction. Further, in the vicinity of the step 131, the protruding portion 132 protrudes from the column portion 12. Therefore, as will be described later, the step 131 of the locking piece 13 is configured to be locked to the periphery of the opening after the column portion 12 is inserted into the opening of the vehicle body.

  Further, as illustrated in FIGS. 2 and 5, the hollow portion 121 of the column portion 12 reaches the base portion 11 and opens to the lower surface 112 side of the base portion 11. As a result, a circular opening region 113 is formed on the lower surface 112 of the base 11. Then, on the lower surface 112 of the base 11, the pair of protrusions 14 are disposed around the opening region 113 formed by the hollow portion 121. In the present embodiment, as will be described later, the movement of the adhesive is blocked by the pair of protrusions 14, and the fixture 1 can be favorably bonded to the glass plate 2.

  Specifically, as illustrated in FIG. 4, the pair of protrusions 14 are disposed so as to face each other across the opening region 113 in the extending direction of the base 11. However, the arrangement of the protrusions 14 is not limited to such an example, and can be determined as appropriate in the peripheral region of the opening region 113. The peripheral region of the opening region 113, that is, the range in which each projection 14 can be installed is, for example, that the adhesive flows into the opening region 113 when the fixture 1 is bonded to the glass plate 2. 14 can be reduced or prevented.

  Moreover, each protrusion part 14 is extended in the front-back direction, and is formed in the elongate rectangular parallelepiped shape. That is, the extending direction of each protrusion 14 intersects the extending direction of the base 11. Furthermore, the width in the front-rear direction of each protrusion 14 (the length in the vertical direction in FIG. 4) is larger than the diameter of the opening region 113. And the height (length of the up-down direction of FIG. 2) of each projection part 14 is the grade which can block at least one part of the movement of the adhesive agent produced when the fixing tool 1 is adhere | attached on the glass plate 2. FIG. Configured at a height of

  Such a fixture 1 can be produced by any method. For example, the fixture 1 can be integrally formed of any material. The material of the fixture 1 may be appropriately selected according to the embodiment. The material of the fixture 1 may be an elastically deformable material or a material that is not elastically deformable. In the present embodiment, the fixture 1 is made of an elastically deformable material. Examples of the elastically deformable material include PBT (polybutylene terephthalate), nylon 6,6, polyacetal, and the like.

  Here, in order to form the hollow portion 121 of the column portion 12 when the fixture 1 is integrally formed, a portion that fills the hollow portion 121 is provided in a mold for molding the fixture 1. In this embodiment, since the hollow part 121 is opened to the lower surface 112 side of the base part 11, when the mold for molding the fixture 1 is composed of an upper mold and a lower mold, the hollow part 121 is filled. The part is provided in the lower mold. That is, since such a lower mold is used, the opening region 113 is formed on the lower surface 112 of the base 11 when the fixture 1 is integrally formed.

  In addition, when the opening region 113 is arranged on the lower surface 112 of the base portion 11 as described above, the hollow portion 121 can be formed by simply pulling the lower mold downward, so that the fixture 1 is formed. The upper and lower molds need only slide in the vertical direction. That is, for example, when the portion that fills the hollow portion 121 is pulled out from the side surface of the column portion 12, it is not necessary to slide the upper mold and the lower mold in the vertical direction, and the portion that fills the hollow portion 121 is slid in the left-right direction. It is necessary to provide a mechanism. On the other hand, since the fixture 1 according to the present embodiment can be integrally formed without such a mechanism, the cost of the apparatus for manufacturing the fixture 1 can be suppressed.

  Note that double-sided tape 31 is attached to both ends of the lower surface 112 of the base 11. Therefore, according to the said structure, the both ends of the lower surface 112 of the base 11 can be adhere | attached on the glass plate 2 with this double-sided tape 31. FIG. However, this double-sided tape 31 may be omitted.

  Moreover, the front-end | tip part 123 of the pillar part 12 has a taper so that it may taper to the front-end | tip (upward) side. Here, in this embodiment, the opening area | region 113 formed when the fixing tool 1 is integrally molded is arrange | positioned at the lower surface 112 side. For this reason, since such an opening region 113 is not formed on the distal end portion 123 side of the column portion 12, the distal end portion 123 can be made relatively thin. Thereby, the column part 12 can be easily introduced into the opening provided in the fixed member (vehicle body). That is, the glass plate structure 10 can be easily attached to the fixed member (vehicle body).

§2 Usage Method Next, a method for attaching the glass plate 2 to the vehicle body of the automobile with the fixture 1 will be described with reference to FIGS. Specifically, the step of attaching the glass plate 2 to the vehicle body with the fixture 1 includes the step of adhering the fixture 1 to the glass plate 2 (adhesion step), and the step of attaching the glass plate 2 to which the fixture 1 is adhered to the vehicle. It can be divided into a process of attaching to the vehicle body (attachment process). Hereinafter, each step will be described. However, each process described below is merely an example of a method of attaching the glass plate 2 to the automobile body with the fixture 1, and the steps described below are omitted as appropriate according to the embodiment. , Substitutions and additions are possible. Further, the following steps may be performed manually or automatically by an apparatus.

[Adhesion process]
First, the process (adhesion process) which adhere | attaches the fixing tool 1 to the glass plate 2 is demonstrated using FIG.7 and FIG.8. That is, the process of configuring the glass plate structure 10 including the glass plate 2 and the fixture 1 will be described. FIG. 7 schematically illustrates a state in which the adhesive 32 is applied to the lower surface 112 of the fixture 1 according to the present embodiment. FIG. 8 schematically illustrates a scene in which the fixture 1 according to this embodiment is attached to the glass plate 2.

  Adhesion of the fixture 1 to the glass plate 2 can be performed, for example, as follows.

  First, as illustrated in FIG. 7, the adhesive 32 is applied to the lower surface 112 of the fixture 1 in a bead shape. The type of the adhesive 32 to be used can be appropriately selected according to the embodiment. The adhesive 32 may be, for example, an epoxy resin adhesive, a urethane resin adhesive, a silicone adhesive, or the like.

  The amount and range of the adhesive 32 to be applied can be set as appropriate according to the embodiment. It is preferable to set the amount and range of the adhesive 32 so that the adhesive 32 does not protrude from the lower surface 112 of the fixture 1 even when the lower surface 112 of the fixture 1 is pressed against the surface of the glass plate 2. In the present embodiment, as illustrated in FIG. 7, an appropriate amount of adhesive 32 is applied to the lower surface 112 including the opening region 113. For example, 1.2 g of adhesive 32 is applied to the lower surface 112. However, the region to which the adhesive 32 is applied is not limited to such an example, and may be set so as not to include the opening region 113.

  Next, as illustrated in FIG. 8, the fixture 1 having the adhesive 32 applied to the lower surface 112 is pressed against the glass plate 2. In this embodiment, the glass plate 2 is curved. For this reason, the fixture 1 is pressed against the glass plate 2 with a stronger force in the direction of the arrow T than when the fixture 1 is bonded to a flat glass plate.

  Specifically, the fixture 1 is made of an elastically deformable material. Therefore, when a force in the direction of arrow T is applied to the fixture 1 with both end portions of the base portion 11 in contact with the surface of the glass plate 2, the base portion 11 is gradually deformed. The central portion of the base 11 approaches the surface of the glass plate 2 so as to be convex. Furthermore, when the lower surface 112 and the surface of the glass plate 2 approach each other beyond the thickness of the applied adhesive 32, the adhesive 32 is sandwiched between the lower surface 112 of the fixture 1 and the surface of the glass plate 2 and is applied. It gradually spreads outside. When the adhesive 32 is cured, the fixture 1 is bonded to the glass plate 2. In the present embodiment, as illustrated in FIG. 1, since the two fixtures 1 are bonded to the glass plate 2, the above process is performed for each fixture 1. Thereby, the glass plate structure 10 is completed.

  In addition, when the height (length in the vertical direction in FIG. 2) of each protrusion 14 is larger than the bending amount D of the region of the glass plate 2 to which the fixture 1 is bonded, the force in the direction of the arrow T is applied to the fixture 1. Even if is added, almost the entire lower surface 112 of the fixture 1 does not come into contact with the surface of the glass plate 2, and the fixture 1 may not be properly adhered to the glass plate 2. Therefore, the height of each protrusion 14 is preferably smaller than the amount of curvature D of the region of the glass plate 2 to which the fixture 1 is bonded. Here, as illustrated in FIG. 8, the bending amount D of the region of the glass plate 2 to which the fixture 1 is bonded is, for example, each protrusion when the both ends of the lower surface 112 are in contact with the glass plate 2. 14 can be defined by the distance between the lower surface 112 and the surface of the glass plate 2 corresponding to the position corresponding to 14.

[Installation process]
Next, the process (attachment process) of attaching the glass plate 2 to which the fixing tool 1 is bonded to the fixed member (vehicle body) will be described with reference to FIGS. 9 and 10. FIG. 9 schematically illustrates a scene where the glass plate structure 10 according to the present embodiment is attached to the vehicle body 5. FIG. 10 is a cross-sectional view schematically illustrating a state in which the glass plate structure 10 according to this embodiment is attached to the vehicle body 5. The vehicle body 5 is specifically a window frame to which a windshield is attached.

  Attachment of the glass plate 2 to which the fixture 1 is bonded to the vehicle body 5 can be performed, for example, as follows. First, as illustrated in FIG. 9, the glass plate structure 10 is held, and the held glass plate structure 10 is moved toward the vehicle body 5. An opening 51 corresponding to each fixture 1 is provided in the vehicle body 5. The openings 51 of the vehicle body 5 and the column portions 12 of the fixtures 1 are appropriately aligned. Therefore, the column portion 12 of each fixture 1 can be inserted into the corresponding opening 51.

  Next, the glass plate structure 10 is further moved, and the column portion 12 of each fixture 1 is inserted into the back side of the corresponding opening 51. At this time, the protrusion 132 of the locking piece 13 of each fixture 1 comes into contact with the periphery of each opening 51. Then, as the column portion 12 of each fixture 1 is inserted into each opening 51, the force acting on the protrusion 132 from the periphery of the opening 51 increases, and each locking piece 13 enters the hollow portion 121. Elastically deforms in the direction. Thereby, the column part 12 of each fixing tool 1 can be inserted in the back | inner side of each opening part 51. FIG.

  And after inserting the column part 12 of each fixing tool 1 in each opening 51 of the vehicle body 5, specifically, after the step 131 of each locking piece 13 passes through each opening 51, each locking piece 13 returns to the original position, and the step 131 of each locking piece 13 is locked to the periphery of each opening 51. That is, as illustrated in FIG. 10, the locking piece 13 is prevented from coming off, and the glass plate 2 can be fixed to the vehicle body 5. Thus, in this embodiment, the glass plate 2 to which the fixture 1 is bonded can be attached to the vehicle body 5. Note that the glass plate 2 may be permanently fixed to the vehicle body 5 with an adhesive or the like after the attaching step.

[Feature]
The fixture 1 described above can fix the glass plate 2 to the vehicle body 5 satisfactorily by having the following characteristics. That is, when the fixture 1 is bonded to the glass plate 2, the distance between the lower surface 112 of the fixture 1 and the surface of the glass plate 2 can be increased by the height of each protrusion 14. Therefore, in the bonding step, the lower surface 112 of the fixture 1 is prevented from being pressed too much against the glass plate 2, and the distance between the lower surface 112 of the fixture 1 and the surface of the glass plate 2 is determined by the distance between the projections 14. The height can be kept moderate. Accordingly, it is possible to prevent the adhesive 32 applied to the lower surface 112 from spreading too much due to the pressure applied by the lower surface 112 of the fixture 1 and the surface of the glass plate 2 during the bonding process. That is, the adhesive 32 can be prevented from protruding from the lower surface 112 of the fixture 1, and an appropriate amount of the adhesive 32 can be retained between the lower surface 112 of the fixture 1 and the surface of the glass plate 2. Thus, the fixture can be satisfactorily adhered to the glass plate with an appropriate amount of adhesive.

  Further, the protrusion 14 for preventing the adhesive 32 from sticking out can be appropriately provided without depending on the shape of the base 11 bonded to the glass plate 2. That is, the protrusion of the adhesive 32 can be prevented as described above with a very simple configuration in which the protrusion 14 is provided on the adhesive surface (the lower surface 112) of the base 11.

  In addition, in this embodiment, an opening region 113 formed by the hollow portion 121 of the column portion 12 is provided on the lower surface 112 side on which the adhesive 32 is applied. Therefore, in the bonding step, the adhesive 32 spreading by the lower surface 112 of the fixture 1 and the surface of the glass plate 2 can enter the hollow portion 121 of the column portion 12 through the opening region 113. If the amount of the adhesive 32 reaching the locking piece 13 enters the hollow portion 121, the locking piece 13 does not function during the mounting step for attaching the glass plate 2 to the vehicle body. There is a possibility that an attachment failure that cannot attach 2 to the vehicle body may occur.

  On the other hand, in the present embodiment, a pair of protrusions 14 are arranged around the opening region 113. Therefore, the pair of protrusions 14 can block the movement of the adhesive that is about to spread due to the pressure generated by the lower surface 112 of the fixture 1 and the surface of the glass plate 2. In particular, in this embodiment, the base 11 extends in the left-right direction, and the adhesive 32 is applied in a bead shape along this direction. Each protrusion 14 extends in a direction perpendicular to the direction in which the base 11 extends. Therefore, each protrusion 14 can particularly block movement of the adhesive 32 that tends to spread in the extending direction of the base 11. More specifically, the amount of the adhesive 32 that moves between the inside (the side where the opening region 113 exists) and the outside (the end of the base 11) of the pair of protrusions 14 can be reduced or prevented. .

  This can reduce or prevent the adhesive 32 from flowing into the vicinity of the opening region 113, and can prevent a large amount of the adhesive 32 from entering the hollow portion 121 through the opening region 113. That is, it is possible to prevent a mounting failure caused by the locking piece 13 being solidified by the adhesive 32. Therefore, according to the present embodiment, it is possible to prevent an attachment failure in which the fixture 1 is detached due to a load acting on the fixture 1 after the above-described attachment step of attaching the glass plate 2 to the vehicle body is completed. it can. In the present embodiment, the adhesive 32 may be allowed to enter the hollow portion 121 to such an extent that such attachment failure does not occur, that is, to the extent that the locking piece 13 does not harden.

  In the present embodiment, the glass plate 2 is curved. Therefore, when the force in the arrow T direction is lost after the lower surface 112 of the fixture 1 is pressed against the glass plate 2 and the adhesive 32 is cured during the bonding step, the base 11 of the fixture 1 is removed. Tries to return to the original shape, and the area near the opening area 113 on the lower surface 112 may be slightly separated from the glass plate 8. Then, when the adhesive 32 in the region near the opening region 113 is small, that is, when the thickness of the adhesive 32 is small, the surface of the lower surface 112 of the fixture 1 and the glass plate 2 are bonded. The adhesive 32 cannot be adhered, and the adhesive strength in the area near the opening area 113 is lowered. The area in the vicinity of the opening area 113 is an area immediately below the column portion 12, and is an area where a load such as the glass plate 2 is easily applied. Therefore, when the adhesive strength in this region is low, there is a possibility that a mounting failure occurs in which the fixing tool 1 is detached due to a load acting on the fixing tool 1.

  On the other hand, in the present embodiment, the adhesive 32 is applied including the opening region 113. The pair of protrusions 14 can reduce or prevent the adhesive 32 applied to this region from flowing to other regions. Further, the thickness of the adhesive 32 can be ensured by the height of the pair of protrusions 14. For this reason, a certain amount of the adhesive 32 can be retained in the region immediately below the column part 12, thereby increasing the adhesive strength in this region. Therefore, according to the present embodiment, it is possible to prevent an attachment failure in which the fixture 1 is detached due to a load acting on the fixture 1 after the above-described attachment step of attaching the glass plate 2 to the vehicle body is completed. it can.

  Moreover, in this embodiment, the base 11 of the fixture 1 is formed in a flat shape with an elastically deformable material. Therefore, in the bonding step, the base 11 of the fixture 1 can be deformed into the shape of the surface of the glass plate 2 by pressing against the surface of the glass plate 2. That is, the same fixture 1 can be bonded to the glass plate 2 having different curvatures. Therefore, by forming the base portion 11 of the fixture 1 in a flat shape with an elastically deformable material, the fixture 1 can be easily adapted to various glass plates having different shapes.

  Further, for example, when the fixture 1 is manually bonded to the glass plate 2, the operator may grip the base 11 when the elastically deformable base 11 is crimped to the curved glass plate 2. The column part 12 may be gripped. However, since the thickness of the base 11 is relatively thin, it is easier to press the lower surface 112 of the base 11 against the surface of the glass plate 2 than when the base 11 is gripped. It is hard to make a mistake in the bonding position.

  However, when the pillar portion 12 is gripped and the lower surface 112 of the base portion 11 is pressed against the surface of the glass plate 2, the operator's force is likely to act on the region immediately below the pillar portion 12. Therefore, the adhesive 32 is likely to be spread around the opening region 113 immediately below the column part 12, and the adhesive 32 may easily enter the hollow part 121 through the opening region 113.

  On the other hand, according to the above-described embodiment, each protrusion 14 disposed on the lower surface 112 is disposed around the opening region 113. That is, each protrusion 14 is disposed almost directly below the pillar 12. Therefore, even if the pillar portion 12 is gripped and the lower surface 112 of the base portion 11 is pressed against the surface of the glass plate 2, the peripheral portion of the opening region 113 on the lower surface 112 is brought into close contact with the surface of the glass plate 2 by each projection 14. Can be prevented. Thus, it is possible to reduce or prevent the adhesive 32 from flowing into the opening region 113 and to reduce or prevent the adhesive 32 from entering the hollow portion 121 through the opening region 113.

  Moreover, in this embodiment, the double-sided tape 31 is affixed on the both ends of the lower surface 112 of the fixing tool 1, and the both ends of the lower surface 112 are adhere | attached on the surface of the glass plate 2 with the said double-sided tape 31 in the said adhesion process. can do. Therefore, in the bonding step, after the lower surface 112 of the fixture 1 is pressed against the glass plate 2 and before the adhesive 32 is cured, the fixture 1 and the glass plate 2 are fixed by the double-sided tape 31. It is possible to prevent the lower surface 112 of the fixture 1 from being separated from the surface of the glass plate 2. In addition, the distance between the lower surface 112 of the fixture 1 and the glass plate 2 can be kept moderate by the thickness of the double-sided tape 31. Thereby, the thickness of the layer of the adhesive agent 32 can be ensured appropriately, and the adhesive strength between the fixture 1 and the glass plate 2 can be increased. Therefore, since the fixture 1 can be firmly bonded to the glass plate 2, the glass plate 2 can be satisfactorily fixed to the vehicle body 5 according to the fixture 1 according to the present embodiment.

  In this embodiment, since the glass plate 2 is curved, the lower surface 112 of the fixture 1 is pressed against the surface of the glass plate 2 with a relatively strong force. Therefore, in such a case, in particular, the adhesive 32 easily protrudes from the lower surface 112, and the adhesive 32 easily enters the hollow portion 121. Therefore, in the scene where the glass plate 2 is curved, the effect of preventing the above-described defect from occurring by providing the protrusions 14 on the lower surface 112 to which the adhesive 32 is applied is further expected.

§3 Modifications As described above, the embodiments of the present invention have been described in detail. However, the above description is merely an illustration of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Regarding each component of the glass plate structure 10, the component may be omitted, replaced, and added as appropriate according to the embodiment. Moreover, the shape and size of each component of the glass plate structure 10 may be appropriately determined according to the embodiment. For example, the following changes can be made.

<Glass plate>
For example, regarding the specific configuration of the glass plate 2, omission, change, replacement, and addition of components may be appropriately performed according to the embodiment. For example, the glass plate 2 has a shape curved forward, but may be a flat shape. Moreover, although the said glass plate 2 is utilized as a windshield of a motor vehicle, it may be utilized as a window glass attached to the other part of a vehicle, and may be utilized other than a vehicle.

  Moreover, the glass plate 2 which concerns on the said embodiment is comprised by the glass plate of 1 sheet. However, the glass plate 2 can have various configurations, and may be configured of laminated glass having a plurality of glass plates, for example. This laminated glass includes, for example, an outer glass plate and an inner glass plate. A resinous intermediate film may be disposed between the outer glass plate and the inner glass plate.

<Fixing tool>
For example, regarding the specific configuration of the fixture 1, the components may be appropriately omitted, changed, replaced, and added according to the embodiment. For example, the base 11 of the fixture 1 has a flat and horizontally long rectangular parallelepiped shape, but may be formed in other shapes. The column portion 12 of the fixture 1 is formed in a cylindrical shape having a taper at the distal end portion 123, but may be formed in other shapes. The opening region 113 formed on the lower surface 112 of the base 11 has a circular shape, but may have a shape other than this. The locking piece 13 may have any shape as long as it can be locked to the periphery of the opening of the fixed member. The shape of each component of the fixture 1 can be appropriately selected according to the embodiment.

  Further, for example, the column portion 12 extends straight upward. However, the pillar portion 12 may extend with an inclination. The extending direction of the column part 12 can be appropriately selected according to the embodiment.

  Further, for example, in the fixture 1, the pair of protrusions 14 are arranged so as to face each other across the opening region 113 in the extending direction of the base 11. However, the number of protrusions 14 is not limited to two, but may be one or three or more. Further, the arrangement of the protrusions 14 may be appropriately set according to the embodiment.

  For example, in the fixture 1, the width in the front-rear direction of each protrusion 14 is larger than the diameter of the opening region 113. However, the length of each protrusion 14 does not have to be limited to such an example. If the protrusion 14 can block the movement of the adhesive as much as possible, the diameter of the opening region 113 is not limited. May be smaller.

  Further, for example, in the fixture 1, each protrusion 14 is formed in a rectangular parallelepiped shape extending in the front-rear direction. However, the shape of the protrusion 14 is not limited to such an example, and can be appropriately selected according to the embodiment. For example, the protrusion 14 of the fixture 1 may be replaced with the protrusion 15 illustrated in FIGS. 11 and 12.

  11 and 12 schematically illustrate a fixture 1A according to a modification. FIG. 11 is a bottom view schematically illustrating the fixture 1A. FIG. 12 is a front view schematically illustrating the fixture 1A. This fixing tool 1A has the same configuration as that of the fixing tool 1 according to the above-described embodiment except for the protruding portion 15. Therefore, the same code | symbol is used about the component similar to the fixing tool 1 which concerns on the said embodiment, and description is abbreviate | omitted.

  In this modification, the protrusion 15 of the fixture 1 </ b> A is configured to surround the opening region 113. Specifically, since the opening region 113 is circular, the protrusion 15 of the fixture 1A is formed in a cylindrical shape. However, when the protrusion 15 is configured to surround the opening region 113, the shape of the protrusion 15 does not necessarily correspond to the shape of the opening region 113. Further, the inner diameter of the protrusion 15 corresponds to the diameter of the opening region 113. However, the inner diameter of the protrusion 15 may be larger than the diameter of the opening region 113.

  According to this configuration, it is possible to satisfactorily prevent a large amount of adhesive from flowing into the opening region 113 from a region other than the opening region 113, and thereby a large amount of adhesion from the opening region 113 to the hollow portion 121. It is possible to prevent the agent from entering. Further, by making the inner diameter of the protrusion 15 the same as the diameter of the opening region 113, the lower surface 112 of the base 11 can be divided into the opening region 113 and a region other than the opening region 113. Accordingly, it becomes easy to apply the adhesive while avoiding the opening region 113, and it becomes easy to adhere the region directly below the column part 12 to the surface of the glass plate 2 except for the opening region 113. Therefore, the adhesive strength in the region immediately below the column portion 12 can be increased. Therefore, according to the fixture 1A according to the modified example, the glass plate 2 can be satisfactorily fixed to the fixed member (vehicle body).

  Further, for example, in the fixture 1, the protrusions 14 are arranged around the opening region 113. However, the arrangement of the protrusions 14 is not limited to such an example, and may be set as appropriate within the lower surface 112 of the base 11.

  Even if the protrusions 14 are not arranged around the opening region 113, when the lower surface 112 of the base 11 is crimped to the surface of the glass plate 2, the protrusions 14 are arranged between the lower surface 112 of the base 11 and the surface of the glass plate 2. It can act to keep the distance. Thereby, even after the lower surface 112 of the base 11 is pressure-bonded to the surface of the glass plate 2, the adhesive 32 having an appropriate thickness can be kept on the lower surface 112. That is, the fixture 1 can be satisfactorily adhered to the glass plate 2 by an appropriate amount of the adhesive 32.

  Moreover, when the lower surface 112 of the base 11 is pressure-bonded to the surface of the glass plate 2, at least a part of the flow of the adhesive spread on the lower surface 112 can be reduced. Accordingly, each protrusion 14 can reduce the adhesive 32 from flowing into the hollow portion 121 through the opening region 113. That is, it is possible to prevent the attachment failure of the fixture 1 caused by the locking piece 13 being solidified by the adhesive 32.

  Moreover, in the said embodiment, the column part 12 has the hollow part 121, and is formed in the hollow cylinder shape. However, the column part 12 may not be limited to such a shape, and may be formed in a solid column shape. In this case, the opening region 113 may not be formed on the lower surface 112 of the base 11.

<Glass plate structure>
The glass plate structure 10 according to the above embodiment is used as a windshield. However, the use of the glass plate structure 10 is not limited to a windshield of an automobile, and can be appropriately selected according to the embodiment. Further, the member to be fixed is not limited to the body of the automobile, and any member that can fix the glass plate 2 can be appropriately selected according to the embodiment. Moreover, the number of the fixtures 1 bonded to the glass plate 2 is not limited to two, but may be one or three or more. Moreover, in the said embodiment, the fixing tool 1 is utilized in order to temporarily fix the glass plate 2 to a vehicle body. However, the purpose of using the fixture 1 is not limited to such an example, and may be appropriately selected according to the embodiment.

  Examples of the present invention will be described below. However, the present invention is not limited to this embodiment. In order to examine how much the adhesive 32 applied to the lower surface 112 of the fixture 1 penetrates into the hollow portion 121 of the column portion 12 when the fixture 1 is bonded to the glass plate 2 with an adhesive, Examples and comparative examples were prepared.

  First, the example which has the structure similar to the fixing tool 1 which concerns on the said embodiment was integrally molded with the polybutylene terephthalate resin (PBT resin). The length in the vertical direction (length in the left-right direction in FIG. 4) of the base of the fixture according to the example was 70 mm, and the length in the horizontal direction (length in the vertical direction in FIG. 4) was 11.5 mm. Moreover, the thickness (length in the vertical direction in FIG. 2) of the base of the fixture according to the example was 1 mm, and a rib illustrated in FIG. Furthermore, a column part was provided at substantially the center of the base part, and an opening region having a diameter of 3.8 mm was formed on the lower surface of the base part.

  And it comprised so that a pair of protrusion part might be provided so that this opening area | region might be pinched | interposed. The vertical length (vertical length in FIG. 4) of each protrusion of the fixture according to the example was 5 mm, and the horizontal length (horizontal length in FIG. 4) was 1 mm. The height of each protrusion (vertical length in FIG. 2) was 0.4 mm. Furthermore, the distance between each protrusion and the opening region was 3 mm.

  Next, the fixture according to the example was manufactured by the above method, and both the protrusions were scraped off by a known method, so that the fixture according to the comparative example was manufactured. That is, a comparative example having the same configuration as the fixture according to the example was prepared except that both protrusions were not provided.

  1.2 g of an epoxy-based adhesive was applied in a bead shape so as to include an open area on each of the lower surfaces of the fixtures according to Examples and Comparative Examples manufactured as described above. And the fixing tool which concerns on the Example and comparative example which apply | coated the adhesive agent was each pressed against the curved glass plate manually, and each fixing tool was adhere | attached on the glass plate. Then, the pillar part of each fixing tool was cut out and it was observed how much adhesive agent penetrate | invaded into the hollow part of each fixing tool. 13 and 14 show the results. In addition, the used glass plate was curving so that a curvature radius might be 1469 mm in the left-right direction and a curvature radius might be 1924 mm in the up-down direction.

  FIG. 13 shows the result of the fixture according to the example. FIG. 14 shows the result of the fixture according to the comparative example. As indicated by the arrow 20 in FIG. 13, in the fixture according to the example, the adhesive hardly penetrated into the hollow portion. On the other hand, as indicated by an arrow 21 in FIG. 14, a large amount of adhesive entered the hollow portion. Further, in the fixture according to the example, the adhesive did not protrude from the lower surface. On the other hand, as indicated by an arrow 22 in FIG. 14, in the fixture according to the comparative example, the adhesive protruded from the lower surface.

  Therefore, from the comparison between the example and the comparative example, by providing the protrusions around the opening region, in particular, by providing a pair of protrusions so as to sandwich the opening region, the amount of adhesive entering the hollow portion can be reduced. It was found that it can be greatly reduced. In addition, a gap can be provided between the lower surface of the fixture and the surface of the glass plate by the height of the protrusion, whereby the adhesive is pressed when the lower surface of the fixture is pressed against the surface of the glass plate. It was found that can be prevented from protruding from the lower surface. And as a result, it turned out that the glass plate can be satisfactorily fixed to the member to be fixed by the fixture according to the example.
