Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to an opening frame used for attaching glass to an opening in a door body.

Recently, it has been used as glass for areas where it is not possible to install lattices or shutters, such as entrance doors of houses.
Products using laminated tempered glass have appeared. By using such tempered glass, it will not be easily broken by external impact.
It is ideal for crime prevention. However, even if such tempered glass is used, no effect will be obtained if the glass itself comes off due to an external impact. For example, FIG. 1 shows such a conventional example, in which the mounting plate 2 is attached to the end face of the opening of the door 1 in FIG. 2 with screws 3, and the space between the side edge of the opening and the glass 4 is Inner and outer frames 5, 6 for holding glass that are installed across
Two clamping pieces 7 and 8 are respectively provided protrudingly, and the gaps between the clamping pieces 7 and 8 are fitted to both ends of the mounting plate 2, respectively, and the glass 4 side edges of each frame 5 and 6 are fitted into the gaps between the clamping pieces 7 and 8. The glass 4 is supported by a bead 9 attached to the section. However, in such a configuration, each of the frames 5 and 6 is supported only by the elastic clamping force of the clamping pieces 7 and 8, so when a strong impact from the outside is applied, the inner frame There is a drawback that 6 is off.
Therefore, in order to prevent such inconvenience, conventionally, as shown in the figure, a screw 10 is screwed in from inside the inner frame 6 through the inner frame 6 and the mounting plate 2. However, if this is done, the heads of the screws 10 are exposed to the outside of the inner frame 6, which impairs the design.

Conventionally, when attaching a mirror plate to a door opening, the mirror plate and a support plate are both fixed with screws to an outer frame fixed to the end of the door opening, and the inner frame is engaged with the support plate. There is one that can be attached (see Utility Model Application Publication No. 54-92628). According to this conventional structure, the head plate is fixed to the outer frame with screws, so there is less risk of it coming off due to external impact. Although screws can be inserted and fixed in this way, such a mounting structure cannot be adopted because screws cannot be inserted into glass. Additionally, in the unlikely event that the glass breaks or the design of the glass changes, the glass must be removed and replaced, and in such cases it is necessary to be able to easily remove the glass. It is. That is, in the past, there has been no glass that does not easily come off even when a strong impact force is applied to the glass from the outside, and that also allows the glass to be easily removed for replacement.

This invention was made with the aim of eliminating such drawbacks of the prior art.

In order to achieve the above object, the present invention includes an outer frame body that spans the outer edge of the opening and the outer edge of the glass, and is provided with an attachment piece to the end face of the opening, and an outer frame body that is screwed to the attachment piece. and an inner frame body extending over the inner edge of the opening and the inner edge of the glass, and the supporting member is formed with an engaging piece that protrudes toward the inner edge of the opening and the inner edge of the glass, Grooves are formed on the inner side of the opening of the inner frame body and on the inner side of the outer edge of the glass, respectively, to engage with the engagement portions of the tips of the engagement pieces, and grooves are formed on the inner edge of the opening of the inner frame and on the inner side of the outer edge of the glass, and grooves are formed to engage with the engagement portions of the tips of the engagement pieces, and It is characterized in that a glass bead is sandwiched between the stepped portion at the tip of the joining piece and the end face of the inner frame.

Hereinafter, the configuration of the present invention will be explained based on an illustrated embodiment. In FIGS. 3 and 4, 11
2 is an outer frame body that is attached across the outer edge 40 of the opening of the door 1 and the outer edge of the glass 4 shown in FIG. A concave groove 13 into which the holder is fitted is formed. Reference numeral 14 denotes a mounting piece integrally provided inwardly from the inner surface of the approximately central portion of the outer frame 11, and the mounting piece 14 has two pieces on one side thereof that abut against the opening end face 15. legs 16, 16
It is fixed to the opening end surface 15 with a screw 17 inserted from the glass 4 side. Similarly, a groove 18 is formed on the side surface of the mounting piece 14 on the glass 4 side, as shown in FIG.

Reference numeral 19 denotes a support member provided with a mounting main body portion 20 that is attached to the mounting piece 14, and the main body portion 20 is joined to the side surface of the mounting piece 14, and the glass 4
It is fixedly supported by screws 21 inserted from the side. Furthermore, an engagement protrusion 23 that protrudes toward the opening end surface 15 is formed at the outer end of the opening 22 of the attachment body 20, and the groove 18 of the attachment piece 14
is engaged to. Further, at both ends of the opening 22 of the mounting main body 20 in the inner and outer directions, engaging pieces 26 and 2 are provided which protrude toward the glass 4 and the inner edge 25 of the opening, respectively.
7 are connected integrally at right angles, and the tips of these engaging pieces 26, 27 are engaging portions 26a, 27a facing in a direction substantially perpendicular to the opening end surface 15. Of these, the engagement piece 28 protruding toward the inner edge 25 of the opening has a foot piece 29 that comes into contact with the inner edge 25, and two engagement protrusions 3 on the opposite side surface.
0 and 30 are integrally formed.

In addition, an engagement piece 2 protruding toward the inner edge of the glass 4
7 faces the inner edge of the glass 4.

The inner frame 31 has an end on the inner edge 25 side of the opening and an end on the inner edge side of the glass 4 which are each bent inward in a U-shape, and engagement grooves 32 and 33 are formed at each end. is formed inside. These engagement grooves 32,
33 are the engaging parts 26a and 2 of the support member 19, respectively.
7a, thereby supporting the inner frame 31. Further, the engagement piece 27 of the support member 19 that protrudes toward the inner edge of the glass 4 is bent in the vicinity of the tip engagement portion 27a at a right angle inward of the opening via a step, and this bent portion 34 and the inner side A groove 35 into which a glass bead 36 is inserted is formed between the frame body 21 and the end surface thereof.

The glass bead 36 is fitted into the groove 35 and is securely held between the end surface of the inner frame 31 and the step portion. On the other hand, at the end of the inner frame 31 on the side of the inner edge 25 of the opening, the inner edge 25 of the opening
A foot piece 37 is formed which comes into contact with the foot piece 37, and a stepped portion 38 is formed on the outside of this foot piece 37. 3

30 is an engagement groove formed on the inner surface of the inner frame 31.

In addition, as shown in FIG.
The leg piece 41 that comes into contact with is formed by bending.

In the above configuration, first, even if the glass 4 receives a force inward from the opening 22 due to an impact from the outside, the impact force is transmitted from the glass bead 36 to the support member 19, and this support Part 19
is fixed to the outer frame 11 by screws 21, so that the glass 4 will not come off inward. When attaching this inner frame 31, after attaching the support member 19, for example, the engagement groove 33 on the glass 4 side is engaged with the engagement portion 27a of the support member 19, and then the opposite end By pushing in from the inside of the opening 22, that is, from the outside of the inner frame 31, the engagement groove 32 in this part is engaged with the engagement portion 26a due to its elastic action. vice versa,
To remove it, use the step 38 formed at the end on the inner edge 25 side of the opening and pry it up using appropriate metal fittings.

To replace the glass 4, the groove 35 is opened by removing the inner frame 31.
By moving the glass bead 36 to the right in FIG. 3 or 4, it can be easily removed, or by simply loosening the screw 21 fixing the support member 19 if necessary. Glass 4 can be easily removed.

42 is a filling member interposed between the glass 4 and the opening end surface 15.

As described above, according to this invention, since the glass is supported by the support member through the bead,
There is no risk of it coming off even if it receives a strong impact from the outside, and the disadvantage of having screws on the inner frame as in the past, which spoils the design, is eliminated. Also,
Since the bead supporting the glass is securely held between the engaging piece and the inner frame, there is no risk of it coming off. On the other hand,
When the inner frame is removed, the groove supporting the glass bead is opened, so the glass bead can be easily removed, and the glass itself can be removed by removing the glass bead or by removing the supporting member. This has the advantage that it can be done by simply loosening the supporting screws.
