Description

  The present invention relates to a joinery provided in a building opening of a building, and more particularly to a joinery having a feature in a mounting portion between a vertical frame and a building constituting an opening frame.

When installing a fitting in the housing opening, an opening frame composed of a pair of left and right vertical frames and a pair of upper and lower frames is attached to the housing opening, and a hinged door or a sliding door is attached to the opening frame. As an attachment structure for attaching the opening frame to the housing, for example, there is an attachment structure in which a mounting screw is inserted from the opening surface side of the vertical frame toward the housing, and the inserted screw is screwed into a housing without a pilot hole and fixed. Known (see Patent Document 1 as an example).
By the way, the opening frame composed of the left and right vertical frames and the upper and lower frames is formed to have a certain size for each type of each opening frame, but the size of the opening of the housing may vary depending on the construction conditions. Therefore, an opening frame is set to the dimension which can be installed with a moderate clearance with respect to a housing opening part.

Therefore, when installing the opening frame in the housing opening, if the left and right vertical frames are arranged with reference to the housing opening, the distance (width) between the other vertical frame and the opposite housing is one. It becomes considerably longer (wider) than that of the side.
Therefore, when the vertical frame is screwed to the casing, a screw (tex screw) that is particularly long in accordance with a wide gap between the casings is used to attach the other vertical frame to the casing.

When using a tex screw, it is not easy to keep the tip of the screw in a stable state in a predetermined position when it is inserted through a hole (screw hole) in the vertical frame. In particular, when self-tapping is used to screw a housing without a pilot hole, it is laborious to position the screw to the correct position.
Therefore, conventionally, a screw guide member is attached to the vertical frame, and the tip end portion of the screw passed through the screw hole of the vertical frame is guided by the guide member to be positioned at a predetermined screwing position of the housing.

FIG. 6 is a perspective view showing a conventional vertical frame 10 and a guide member 20 as an example of attaching the vertical frame to the housing using a tex screw, although it is not described in the patent literature.
Here, the vertical frame 10 is formed in a cross-sectional groove shape including a pair of side walls 10a and 10b and a bottom wall 10c as shown in the figure. In addition, on the side wall 10a on the opening side of the vertical frame 10, two screw insertion holes 10d are provided, for example, on the top and bottom. The guide member 20 may be made of any material, but is an annular member made of, for example, plastic. The guide member 20 is formed from a notch 10e cut out from the open end side of the vertical side wall 10b of the vertical frame 10 to the vertical frame 10. Housed inside. In this state, a screw (text screw) 50A inserted from the side wall 10a is inserted. Thus, the guide member 20 is held by the hole 10d and the notch 10e.

A screw (text screw) 50 </ b> A that has passed through the guide member 20 is screwed into the housing 30 from the tip thereof, and the vertical frame 10 is fixed to the housing 30.
As described above, in the conventional method of attaching the vertical frame 10 to the housing 30, the vertical frame 10 can be easily attached and fixed to the housing 30 regardless of the length of the screw 50 </ b> A by using the guide member 20. .
However, in this attachment method, the guide member 20 must be prepared separately, and an operation of mounting the separately prepared guide member 20 on the vertical frame 10 is also required. Therefore, there is a problem in terms of cost and work burden.
Therefore, it is desired to reduce the cost by omitting the guide member 20.

On the other hand, in order to cover the gap between the vertical frame 10 and the housing 30, conventionally, panels (herein referred to as attachments) are mounted vertically and horizontally along the opening frame. Here, when the width of the gap between the vertical frame 10 and the housing 30 is different on the left and right sides of the opening frame, the left and right width (finding width) of the attachment attached to the left and right vertical frames is also different on the left and right. Is used.
The attachment is usually molded into a plate shape using a metal such as an aluminum alloy or a synthetic resin. Conventionally, in the manufacture of the attachment, different molding dies are used for molding attachments having different widths. Therefore, the cost and work burden for attachment processing are large, and suppression thereof is desired.

The opening frame that accommodates the folding door 1 is housed in an opening frame that is configured by combining a pair of left and right vertical frames 10 and an upper and lower frame (not shown). It is attached with screws 50A and 50B.

As shown in the cross-sectional view of FIG. 3, the right vertical frame 10 in FIG. 2 is provided on the flange portion 10 (2) following the hollow portion 10 (1) and on the outer side (upper side in the drawing) of the flange portion 10 (2). Two ridges 10 (3) each having a wedge-shaped portion for attaching the attachment 40 (1) on the wide side are provided integrally. The left and right vertical frames 10 are symmetrical with each other, and the left vertical frame 10 has the same structure.
As shown in FIG. 3, screws 50A and 50B are inserted into the screw holes 10 (4) from the opening side (left side in the figure) of the left and right vertical frames 10, and the distal ends of the screws 50A and 50B are the left and right housings 30. Screwed onto. The screw 50A is the tex screw already described, and is much longer than the normal screw 50B as shown in FIG.

  As shown in FIG. 3, the attachment 40 (1) is configured on the outside as a panel that covers the gap between the vertical frame 10 and the housing 30 when an opening frame (jointing device opening frame) is disposed in the opening of the housing 30. Has been. On the other hand, on the inside thereof, two ridges 40 (1 which engage with the ridge 10 (3) having a wedge-shaped end portion of the vertical frame 10 at one end portion (the left side in the figure, that is, the opening side end portion). ) A is provided. Further, the two protrusions 40 (1) a and the side wall surface 40 (1) b serving as a contact surface between the right end portion of the case 30 and the side wall surface 40 (1) b are protruded inwardly. A flange or guide piece 42b is provided.

FIG. 4 is a cross-sectional view showing a state in which the screws 50A inserted from the insertion holes of the vertical frame 10 are supported and guided by the guide pieces 42a and 42b provided on the attachment 40 (1). In FIGS. 4A and 4B, Different guide pieces 42a and 42b are shown.
That is, the guide piece 42a shown in FIG. 4A has a flat plate-shaped portion extending in the inner direction of the vertical frame 10, and passes through an intermediate position between the distal end portion and the proximal end portion in the inner direction. 44a is provided. The guide hole 44a guides and supports the mounting screw 50A when the vertical frame 10 is attached to the housing 30.
Further, the shaft portion of the screw 50A inserted from the opening side of the vertical frame 10 and passing through the guide hole 44b abuts on the edge portion of the guide hole 44b, and the edge portion supports and guides the screw 50A. Therefore, when the screw 50A is pushed in, the screw 50A is in a stable state, and the tip portion thereof advances straight and comes into contact with a predetermined position (attachment position) of the housing 30. In this state, the vertical frame 10 is fixed to the housing 30 by screwing the screws 50 </ b> A into the housing 30.

  As shown in FIG. 4B, the guide piece 42b shown in FIG. 4B has a tapered portion 46 having a concave surface facing the vertical frame 10 at an intermediate position between the inner end portion and the base end portion. In addition, a guide hole 44b made of a long hole similar to the guide hole 44a shown in FIG. 4A is provided at the center of the tapered portion 46. When the screw 50A is pushed in from the vertical frame 10 side, the guide hole 44b guides and supports the screw 50A in the same manner as the guide hole 44a in FIG. 4A.

4B, when the screw 50A is inserted from the opening side of the vertical frame 10, even if the tip of the screw 50A comes off the guide hole 44b, the tip of the taper 46 is guided. Guide to hole 44b. Therefore, according to this guide piece 42b, the screw 50A can be more easily inserted into the guide hole 44b in combination with the fact that the guide hole 44b is formed as a long hole.
After the screw 50A is inserted into the guide hole 44b, the screw 50A is supported at the two points of the screw hole 10 (4) of the vertical frame 10 and the guide hole 44b. It contacts the predetermined position of the housing 30. In this state, the vertical frame 10 is fixed to the housing 30 by screwing the screws 50 </ b> A into the housing 30.

FIG. 5 is a perspective view of the entire attachment 40 (1) described above as viewed from the inside.
As illustrated, the attachment 40 (1) has a guide piece 42b shown in FIG. 4B, and two guide holes 44b are provided at the top and bottom.

  As described above, the attachment 40 (1) on the right side in FIG. 2 has been described. However, since the interval between the left vertical frame 10 and the housing 30 is narrower than that on the right side as illustrated, the vertical frame 10 is attached to the housing 30. The length of the screw 50B is significantly shorter than that of the screw 50A, and the width of the left attachment 40 (2) (width in the direction of finding) is narrower than that of the attachment 40 (1), and no guide piece is formed.

However, in this case, different molds are required to mold the left and right attachments 40 (1) and 40 (2). Therefore, as already pointed out, there arises a problem that the molding cost of the attachments 40 (1) and 40 (2) increases.
Therefore, the attachments 40 (1) and 40 (2) according to the embodiment of the second invention are configured so that the width of the attachment molded with the same mold can be adjusted according to the fit.

The adjustment of the width of the attachment is here divided between the portion of the attachment 40 (1) where the two protrusions 10 (3) are integrally provided and the portion provided with the guide pieces 42a, 42b. In the present embodiment, the portion adjacent to the protrusion 10 (3) can be divided, but the dividing position of the attachment 40 (1) is not limited to this, and the left attachment 40 (2) in FIG. 2 is necessary. It suffices if it can be divided into
As a dividing method, for example, it is performed by cutting and dividing in accordance with a necessary width. The method of division is arbitrary, but for example, it is necessary to form a thin portion (weakened portion) extending in the longitudinal direction at a predetermined interval in the direction of finding the attachment 40 (1) so that the division is easy. Sometimes it may be cut at that part. Alternatively, a configuration may be used in which attachments divided in advance at a predetermined width in the finding direction (that is, the attachment width on the right side in FIG. 1 in the embodiment) are combined, and the combination is released and divided as necessary. Furthermore, you may just cut | disconnect with a cutter.
In this way, by forming the attachment 40 (1) in advance so that it can be divided, it is possible to manufacture the attachments having different widths in the direction of finding using the same mold, thereby reducing the equipment cost. Can do.

As mentioned above, although embodiment of this invention was described, according to this, the guide member which supports and guides the screw (text screw) for attaching a vertical frame to a housing to the attachment which covers the crevice between a vertical frame and a housing. Since they are provided integrally, the conventional screw guide member for mounting, which is configured separately, can be dispensed with, and the number of parts can be reduced and the cost can be reduced.
In addition, even when the left and right vertical frame shapes are different, the attachment is common, and the width in the direction of finding can be adjusted by simply dividing the attachment. That is, by dividing the common attachment, an attachment without a guide piece can be easily formed. Therefore, the investment for processing the attachment and the work load can be suppressed.
In the above description, the fitting is assumed to be equipped with an attachment having a guide piece on one side of the left and right vertical frames and an attachment not having a guide piece on the other side. Depending on the positional relationship with the left and right vertical frames, an attachment having guide pieces on either side of the left and right vertical frames may be used.
