Description

TECHNICAL FIELD The present invention relates to a hinged door fixture and a hinged door fixing structure.

There are various types of doors in buildings, such as sliding doors (double sliding doors, single sliding doors, single sliding doors), swing doors (single swing doors, parent-child swing doors), and folding doors (single folding doors, double folding doors). . Unlike the sliding door, the hinged door and the folding door have a common structure in which the door plate that constitutes the hinged door or the folding door rotates around a pivot hinge or the like on the hanger side.

Here, regarding the pivot hinge that fixes the edge of the door at the hinged door, the pivot that protrudes upward from the door is inserted into the base notch groove of the base plate and is rotatably attached to the screw of the base plate. A pivot hinge has been proposed in which the base plate and the shaft stop plate are fixed by a fixture at a position different from the screw that is the rotation shaft after the shaft stop plate is rotated to engage the notch groove with the support shaft ( For example, see Patent Document 1).

Utility Model Registration No. 2573573

However, in the pivot hinge described in Patent Document 1, the position of the fixing member that holds the locking posture of the shaft-stopping plate is different from the rotation axis (screw) of the shaft-stopping plate with respect to the base plate. There is a problem that it takes time and effort to align the holes for inserting the fasteners in both the shaft stop plate and the shaft stop plate.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a hinged door fixture and a hinged door fixture that can lock a pivot shaft protruding from the upper end of a door panel with a lock key without taking much time and effort. It is intended to provide structure.

In order to achieve the above object, one aspect of the hinged door fixture according to the present invention is
A hinged door fixture that is fixed to a rail attached to an upper frame member on the suspension side of the hinged door and rotatably positions a door plate that constitutes the hinged door,
a main body accommodated in the rail;
a lock key rotatably attached to the body;
The body is
a pivot bearing recess into which a pivot shaft attached to the upper end of the door plate is fitted;
In a state in which the pivot shaft body is fitted in the pivot bearing recess, the lock key is rotated about the shaft member and engaged with the pivot shaft body, and the lock key is tightened by tightening the shaft member. The engagement of the pivot shaft by is held.

According to this aspect, after the lock key is rotated about the shaft member and engaged with the pivot shaft, the shaft member, which is the rotation shaft, is directly tightened, thereby engaging the pivot shaft with the lock key. combination is preserved. Therefore, the shaft member that serves as the rotation shaft of the lock key and the shaft member that maintains the engagement posture of the lock key are not separate members, and the engagement state of the lock key with respect to the pivot shaft can be quickly maintained. Here, in the following description, the term "swing door" includes general swing doors (single swing door, parent and child swing door) as well as folding doors (single folding door, double folding door), but the fixture of the present invention is applied. The door to be installed is typically a folding door. This embodiment is a fixture for rotatably fixing a door plate on the suspension side. The folding door will be collectively explained as the hinged door.

A hinged door to which the fixture for a hinged door of this aspect is applied is fixed to the hanger side of the rail attached to the upper upper frame member of the opening frame attached to the periphery of the door opening. For example, the hinged door fixture is fitted from the hanger end of the rail, and at a predetermined position relative to the rail, the hinged door fixture is fixed to the rail or to the upper frame member via the rail. In the case of a single hinged door, the door is opened and closed by rotating the door around the pivot bearing recess and the pivot shaft attached to the upper end of the door, which constitute the pivot hinge on the hanger side. On the other hand, in the case of a folding door, for example, two door plates are relatively rotatably attached by hinges, the door plate on the hanging side rotates around the pivot hinge, and the door plate on the door tip side rotates around the pivot hinge. The door is opened and closed by sliding the running runner attached above it to the left and right while being guided by the rail.

On the hanger side, the door plate has pivot shafts attached to its upper and lower ends, and the pivots attached to the upper end of the door plate against the pivot bearing recesses of the hinged door fixture fixed to the upper rail. The upper end of the shaft is fitted. In this state in which a portion of the pivot shaft body is fitted into the pivot bearing recess, the lock key before being rotated is, for example, perpendicular to the longitudinal direction of the rail or inclined, for example, on the inside of the room. It is in a state of being overhanging. By fitting the upper end of the pivot shaft into the pivot bearing recess, in principle the door plate is attached in a non-removable manner. However, if the upper end of the pivot shaft body is only fitted in the pivot bearing concave portion, the door panel may come off when subjected to vibrations during an earthquake, for example. Therefore, by rotating the lock key to engage with the pivot shaft and tightening the shaft member, it is possible to engage and hold (lock) the pivot shaft by the lock key.

When the lock key is rotated to engage with the pivot shaft, the lock key is oriented along the rail and therefore does not protrude from the rail, for example, into the interior of the room. On the other hand, in the state before the lock key is rotated and locked, the lock key is perpendicular to the longitudinal direction of the rail or inclined so that it protrudes, for example, toward the inside of the room. A worker can confirm that it is not locked, and it is possible to prevent forgetting to lock the lock key.

Another aspect of the hinged door fixture according to the present invention is characterized in that the shaft member is formed of a headed bolt.

According to this aspect, since the shaft member is the headed bolt, the bolt can be easily tightened with a tool such as a wrench. For example, after the lock key that protrudes into the room before locking is rotated around the shaft member and engaged with the pivot shaft at the upper end of the door plate, the lock key is inserted into the gap between the upper end of the door plate and the rail. Locking can be completed by inserting a tool such as a wrench and tightening the headed bolt.

In another aspect of the hinged door fixture according to the present invention, the main body further has a fixing means insertion hole through which fixing means for fixing the main body to the upper frame member through the rail is inserted. It is characterized by

According to this aspect, the hinged door fixture can be fixed to the upper frame member via the rail at a desired position in the longitudinal direction of the rail. Here, the "fixing means" includes screws, nails, and the like. For example, a plurality of screw holes are provided at predetermined intervals in the longitudinal direction of the rail, the hinged door fixture is positioned at a desired position on the rail, and the screw is passed through the fixing means insertion hole and the screw hole at that position. The hinged door fixing member is fixed by screwing the fixing means such as the fixing means into the upper frame member from the main body side. In addition, as described above, since the rail has a plurality of screw holes, etc., there are a plurality of places where the fixing means is driven (screwed) into the rail, so the fixing position of the hinged door fixture is not desired. position can be set or adjusted.

In another aspect of the hinged door fixture according to the present invention, the main body has a rail engaging portion that is guided inward from an end portion of the rail while being engaged with the rail,
the lock key is rotatably fixed to the door plate-side surface of the rail engaging portion;
The main body has a door plate facing piece on the door plate side of the fixing means insertion hole,
The door plate facing piece has a pivot shaft restricting groove through which the fixing means can be inserted and through which the pivot shaft cannot be inserted. It is characterized in that it can be freely fitted into the pivot bearing recess.

According to this aspect, the hinged door fixture can be smoothly guided along the rail by the rail engaging portion of the main body. In addition, the main body has a piece opposed to the door plate, and the piece opposed to the door plate is provided with a pivot shaft restricting groove that allows the fixing means to be inserted but does not allow the pivot shaft to be inserted. While the body is slid along the pivot shaft restricting groove, the pivot shaft can be smoothly fitted into the pivot bearing recess without entering the fixing means insertion hole.

In another aspect of the hinged door fixture according to the present invention, the direction of rotation when the shaft member is tightened is opposite to the direction of rotation when the lock key is engaged with the pivot shaft. In one aspect, the lock key is provided with either a holding protrusion or a holding groove that are engaged with each other to hold the engagement attitudes of both when the lock key is engaged with the pivot shaft. , and the other is provided on the main body.

According to this aspect, the lock key is engaged with the pivot shaft even if the rotation direction when the shaft member is tightened and the rotation direction when the lock key is engaged with the pivot shaft are opposite to each other. When the lock key is engaged, the lock key and the holding protrusions and holding grooves respectively provided on the main body are engaged with each other, so that the lock key is released from the engagement posture when the shaft member is rotated to maintain the engagement. can be prevented. Note that the holding projection and the holding groove may be provided on either the lock key or the main body, respectively. In addition, in a configuration in which the direction of rotation when the shaft member is tightened and the direction of rotation when the lock key is engaged with the pivot shaft body are the same, when the shaft member is rotated to maintain engagement, Moreover, since the force is applied to the lock key in the direction to maintain the engagement posture, there is no fear that the engagement posture of the lock key will be released.

Further, one aspect of the hinged door fixing structure according to the present invention is
A hinged door fixing structure for rotatably positioning a door plate that constitutes a hinged door with respect to a rail attached to an upper frame member on the suspension side of the hinged door,

First, a hinged door fixture according to an embodiment will be described with reference to FIGS. 1 and 2. FIG. Here, FIG. 1 is an exploded perspective view of the hinged door fixture according to the embodiment, and FIG. 2 is an assembled perspective view of the hinged door fixture according to the embodiment. In addition, the hinged door fixture 100 shown in FIG. 2 has a posture in which the state shown in FIG. It can be installed with 1 and 2, "above", "upper surface" and the like used in the following description refer to the upper and upper surfaces in the state shown in Figs. is attached, the upper side becomes the lower side, and the upper side becomes the lower side. Further, in FIG. 1, each hole through which the shaft member 60 is sequentially inserted is indicated by a dashed-dotted line arrow. marked with an arrow.

As shown in FIG. 1, the hinged door fixture 100 is formed by stacking a plurality of members. A main body 40 composed of a base 10, a slide base 20, and a lock key pedestal 30, and a lock key 50 attached to the main body 40 with a shaft member 60 as a rotation center are arranged in order from the bottom of the laminated structure. have.

The base 10 is composed of a member formed by bending a steel plate and a resin block body fitted into a part of this member. The members formed by bending the steel plate are the first horizontal piece 11, the first vertical piece 12 extending downward through the bent portion at one end of the first horizontal piece 11, and the first horizontal piece 11. a second vertical piece 13 extending downwards through a bend at the end. Further, a second horizontal piece 14 horizontally extending from the second vertical piece 13 via the bent portion, and a third vertical piece 15 extending upward from the second horizontal piece 14 via the bent portion. have. As shown in FIG. 1, a member formed by bending a steel plate has a linear shape of the number 2 in side view. The lower end of the first vertical piece 12 and the lower surface of the second horizontal piece 14 are at the same height level, so that the base 10 can be placed on a flat surface in a stable posture.

A first elongated hole 16 extending in the longitudinal direction of the base 10 is formed in the first horizontal piece 11 , and a first shaft member insertion hole 17 is formed at a position away from the first elongated hole 16 . The first long hole 16 is a long hole into which the pivot bearing concave portion 23 of the slide base 20 is slidably fitted. On the other hand, the first shaft member insertion hole 17 is provided with a thread groove on the inner wall surface thereof, and is an insertion hole into which the bolt of the headed bolt, which is the shaft member 60, is screwed.

A guide runner stopper 19 made of, for example, rubber is attached to the front surface of the first vertical piece 12, and a hinged door fixture 100 is fixed to the rail, and is attached to the door plate on the edge side of a folding door, which is one form of a hinged door. It functions as a cushioning material when the attached guide runner side pivot shaft comes into contact.

On the other hand, a door plate facing block 18 made of resin is fitted into the recess formed by the second vertical piece 13, the second horizontal piece 14, and the third vertical piece 15, and is connected to each piece by, for example, an adhesive. there is The door plate facing block 18 of the illustrated example has a U-shape when viewed from the side, and a pivot shaft regulation groove 18b is formed in the upper door plate facing piece 18a, and a position corresponding to the pivot shaft regulation groove 18b in the lower piece 18c. is provided with a fixing means insertion hole 18d. When viewed from above, the pivot shaft restricting groove 18b and the fixing means insertion hole 18d communicate with each other. is established. Therefore, a fixing means such as a screw is inserted through the pivot shaft body regulation groove 18b, and an upper frame member (not shown) to which the base 10 is fixed through the fixing means insertion holes 18d and 14a. can be fixed by a fixing means.

In this way, the pivot shaft restricting groove 18b has an opening dimension that allows the tip of a fixing means such as a screw or a tool for tightening the fixing means to enter. By having an opening size that cannot be entered, it functions as a groove that restricts the insertion of the pivot shaft. The door plate facing block 18 may be made of steel instead of resin. may be integrally molded with

Further, in a state in which the door plate facing block 18 is fitted in the recess formed by the second vertical piece 13, the second horizontal piece 14, and the third vertical piece 15, the third vertical piece 15 is positioned closer to the door plate facing block 18 than the door plate facing block 18. It also has an overhanging portion 15a that overhangs sideways. As will be described later, when the hinged door fixture 100 is slid and attached to the rail, the side piece of the rail is engaged with the projecting portion 15a, so that the hinged door fixture 100 can be positioned relative to the rail. be done.

The slide table 20 has a slide table main body 21 formed of a steel plate and having a substantially rectangular shape in plan view. A mortar-shaped pivot bearing recess 23 is formed in the slide table main body 21 by press working. and a hole 24 .

A semicircular groove 22 for fixing means is formed in the longitudinal end face of the slide base body 21 . The pivot bearing recess 23 is a recess that is slidably fitted into the first elongated hole 16 of the base 10 and into which the tip of the pivot shaft attached to the door panel is inserted. On the other hand, the guide projection 25 is a projection that can enter into a guide groove 35 provided on the lower surface of the lock key base 30 to enable rough positioning of the lock key base 30 with respect to the slide base 20 .

Furthermore, the second long hole 24 is a hole through which the shaft member 60 is inserted. The second elongated hole 24 allows the pivot bearing concave portion 23 of the slide base body 21 to slide in the first elongated hole 16 of the base 10 with the shaft member 60 inserted therein. It is considered to be an elongated hole.

The fixing means groove 22 forms an insertion hole through which a fixing means such as a screw is inserted, together with the pivot shaft regulation groove 18b and the fixing means insertion hole 18d.

The lock key pedestal 30 is a pedestal made of resin, and has a pedestal body 31 which is a columnar body having a substantially T-shaped cross section perpendicular to its longitudinal direction. A second shaft member insertion hole 32 penetrating through the pedestal body 31 is formed at the central position of the pedestal body 31 . In addition, on the upper surface of the base main body 31, a first stopper 33 and a second stopper 34 are provided at one diagonal position of the rectangle in plan view so as to protrude upward.

A guide groove 35 extending from the end of the bottom surface toward the center is provided at the center position of the bottom surface of the pedestal body 31, into which the guide protrusion 25 of the slide base 20 is inserted. . By inserting and guiding the guide projections 25 into the guide grooves 35 , the base main body 31 can be roughly positioned with respect to the slide base 20 . After the lock key 50 is rotated to lock the engaged state of the pivot shaft, the shaft member 60 is inserted through the second shaft member insertion hole 32 and the second elongated hole 24 to maintain this locked attitude. By screwing the tip of the shaft member 60 into the shaft member insertion hole 17 , the lock key base 30 is fixed to the slide base 20 . Note that the lock key pedestal 30 may be a steel pedestal.

The lock key 50 has a lock key body 51 made of a steel plate. The lock key body 51 has a pivot engagement groove 52 that engages with the pivot shaft whose tip is fitted in the pivot bearing recess 23, and a lock key body that engages with the pivot shaft when the lock key body 51 is engaged with the pivot shaft. A first stopper engagement groove 53 that engages with the first stopper 33 of the lock key base 30 is provided to restrict further rotation of the lock key 51 . Further, a third elongated hole 54 is formed to extend in the longitudinal direction of the lock key body 51 and through which the shaft member 60 is inserted. Since the lock key 50 can slide with respect to the lock key pedestal 30 within the range of the length of the third elongated hole 54 with respect to the shaft member 60 to be inserted, the length of the first stopper engaging groove 53 is also the length of the lock key. It has a length corresponding to 50 slidable lengths.

The illustrated shaft member 60 inserted through the third elongated hole 54 of the lock key 50 is formed of a headed bolt having a Phillips hole on the upper surface thereof. A headed bolt 60 inserted through the third elongated hole 54 via a washer is screwed through the second shaft member insertion hole 32 and the second elongated hole 24 into the first shaft member insertion hole 17 of the base 10 . are designed to be combined. The illustrated headed bolt 60 is a bolt (bolt with a hexagonal hole) having a nut with a plus hole in the head, but it may be a hexagonal hole bolt with a minus hole or a hexagonal nut without a hole. It may be a hexagonal bolt or the like with a head. The screwing (tightening) of the headed bolt 60 into the first shaft member insertion hole 17 rotates the lock key 50 to engage with the pivot shaft body fitted in the pivot bearing recess 23 to lock it. This is done while maintaining engagement of the pivot shaft by the key 50 .

By laminating the various members shown in FIG. 1 and lightly tightening the shaft member 60 to the extent that the lock key 50 can be rotated, the hinged door fixture 100 shown in FIG. 2 is formed. In FIG. 2, the hinged door fixture 100 is shown with its longitudinal direction directed to the L direction, which is the longitudinal direction of the rail (not shown) to which the hinged door fixture 100 is attached. . As shown in FIG. 2, the pivot bearing concave portion 23 is slidably fitted into the first elongated hole 16, so that the slide base 20 is slidable in the X1 direction along the L direction with respect to the base 10. As shown in FIG. Fixing means (not shown) such as screws are inserted in the Z1 direction into the robot shaft regulation groove 18b, the fixing means insertion hole 18d, and the fixing means insertion hole 14a, and a rail or the like is inserted using a tool. A hinged door fixture 100 is fixed to the upper frame member to which the rail is fixed.

A gap formed between the lock key pedestal 30 having a substantially T-shaped cross section and the slide base 20 serves as the rail engaging portion 70, and the left and right rail engaging portions 70 are the left and right engaging projections of the rail (Fig. (not shown)), the hinged door fixture 100 can be movably locked to the rail in the L direction, which is the longitudinal direction thereof, without being disengaged from the rail.

The lock key 50 rotates about the shaft member 60 in the X3 direction, but the rotation range of the lock key 50 is restricted by the first stopper 33 and the second stopper 34, preventing the lock key 50 from rotating excessively. is suppressed.

Further, when the lock key 50 is rotated to engage with the pivot shaft fitted in the pivot bearing recess 23 and the engagement state of the pivot shaft by the lock key 50 is maintained, the lock key 50 is rotated. The lock key 50 is tightened by tightening the shaft member 60, which is also a shaft, in the X4 direction. In this way, since the pivot shaft of the lock key 50 and the tightening means of the lock key 50 are both the shaft member 60, the lock of the pivot shaft body by the lock key 50 can be achieved without much effort.

Further, when the lock key 50 is rotated and its longitudinal direction is at a position along the longitudinal direction of the base 10 or the slide table 20, the shaft member 60 inserted through the third elongated hole 54 is pushed into the third position. The lock key 50 is slidable in the X2 direction along the L direction within the length range of the three-long hole 54 . In this way, the plurality of members that constitute the hinged door fixture 100 are assembled so as to be mutually slidable in the L direction, which is the longitudinal direction of the rail, so that the door plate can be erected with good ease of installation. is obtained.

Specifically, when fixing the door plate to the suspension base of the rail attached to the upper plate frame, the pivot shaft at the lower end of the door plate must be attached to the rail against the pivot bearing (not shown) below the suspension base. After inserting it obliquely along the rail, the pivot shaft at the upper end of the door plate is similarly obliquely along the rail with respect to the pivot bearing recess 23 of the hinged door fixture 100 fixed to the rail above the hanging base. It is common to fit from the direction. In this installation, a plurality of members that constitute the hinged door fixture 100 slide in the longitudinal direction of the rail, so that the position of the pivot bearing recess 23 can be adjusted to a position where the pivot shaft can be easily fitted. . Therefore, it is possible to erect the door plate while easily guiding the tip of the pivot shaft body to the pivot bearing recess 23 from an oblique direction.

<Swinging door fixed structure>
Next, the hinged door fixing structure according to the embodiment will be described with reference to FIGS. 3 and 4. FIG. Here, FIG. 3 is a perspective view explaining how the pivot shaft body attached to the door plate slides and fits into the pivot bearing concave portion. Moreover, FIG. 4 is a perspective view explaining that the engagement state of the pivot shaft is held by the lock key, and the hinged door fixing structure according to the embodiment is formed.

The pivot shaft 200 shown in FIGS. 3 and 4 is attached to the upper end of a door plate (not shown) on the hanger side that constitutes the hinged door. The hinged door fixture 100 is shown upside down.

The pivot shaft body 200 has a steel shaft member 201 and a resin engagement ring 202 attached to the tip of the steel shaft member 201. The other end of the shaft member 202 is housed inside a resin door plate mounting cylinder 203. It is attached to a compression coil spring 204 housed in the . Therefore, for example, when the pivot shaft 200 is pressed from above in FIG. 3, the compression coil spring 204 contracts and the overall length of the pivot shaft 200 is shortened. Also, by releasing the pressure, the compression coil spring 204 returns to its original length, and the pivot shaft body 200 assumes its original length. In this way, the pivot shaft body 200 is flexible in its longitudinal direction in the Y2 direction. guarantees sex. In addition, since the engagement ring 202 made of resin and having a cushioning function is attached to the tip of the shaft member 201 made of steel, the tip of the shaft member 201 is There is no danger of damage to the pivot bearing recess 23. Furthermore, by fitting the door panel mounting cylinder 203 made of resin with a cushioning effect into the door panel, there is no danger that the door panel mounting cylinder 203 will damage the fitting portion of the door panel.

The main body 40 has a door plate facing piece 18a, and the door plate facing piece 18a allows insertion of a fixing means (not shown) such as a screw, and a pivot shaft having an opening size and shape that prevents the pivot shaft body 200 from being inserted. A body regulation groove 18b is provided. Therefore, when the tip of the pivot shaft body 200 at the upper end of the door plate is slid in the Y1 direction along the pivot shaft body restricting groove 18b, the tip of the pivot shaft body 200 does not enter the fixing means insertion hole 14a. It can be smoothly fitted into the bearing recess 23 . Therefore, as described above, when the tip of the pivot shaft body 200 protruding from the upper end of the door plate is to be fitted into the pivot bearing recessed portion 23 from an oblique direction, the pivot shaft body 200 cannot move along the pivot shaft body restricting groove 18b. The tip can be guided into the pivot bearing recess 23, which also ensures good installation of the door panel.

By fitting the upper end of the pivot shaft body 200 into the pivot bearing recess 23, in principle, the door plate is attached in a manner that does not come off. However, if the upper end of the pivot shaft body 200 is only fitted in the pivot bearing concave portion 23, the door panel may come off when subjected to vibrations during an earthquake, for example. Therefore, as shown in FIG. 4, the lock key 50 is rotated in the X3 direction to engage with the pivot shaft body 200, and the shaft member 60 is rotated in the X4 direction and tightened so that the lock key 50 rotates the pivot shaft body. 200 can be held (locked) in the engaged state.

In the illustrated example, the direction in which the shaft member 60 is rotated (clockwise) when tightening is the same as the direction in which the lock key 50 is engaged with the pivot shaft body 200. Therefore, when tightening the shaft member 60, Even if the lock key 50 rotates further, the engaging posture of the lock key 50 with respect to the pivot shaft body 200 is maintained. On the other hand, if the direction in which the shaft member is rotated when tightening is different from the direction in which the lock key engages with the pivot shaft, the lock key moves away from the pivot shaft when the shaft member is rotated. There is a risk that it will rotate and disengage. Therefore, in preparation for such a case, when the lock key is engaged with the pivot shaft body, a holding protrusion and a holding groove (both not shown) are engaged with each other in order to hold both engagement attitudes. ) is preferably provided on the lock key and the other is preferably provided on the main body.
