Description

[Detailed Description of the Invention] This invention provides a hinged door mechanism that can be opened and closed in both a sliding door type and a hinged type. , relates to a locking device for a hinged door that is useful for preventing the free end of the door body from sagging.

A sliding door with a hinged door mechanism is constructed so that the door body that opens and closes as a sliding door can be opened and closed as a hinged door at any point along its opening/closing path. Half of the width of the opening is opened, and when the door pocket section 1 is opened as a swinging door, the frontage is opened over the entire width. Therefore, they are installed in buildings where the frontage needs to be opened wider than during times when there is no traffic or when a single person carrying a large baggage is out.

With such a sliding door mechanism, when the free end of the door body sags due to its own weight when the door body is opened and closed in a sliding style, the door body interferes with the floor surface and does not function smoothly as a sliding door. Since the door cannot be opened or closed, it is required that the free end of the door does not hang down when the door is opened or closed as a sliding door. In addition, it is extremely dangerous if the door body is opened and closed as a sliding door when it is opened even slightly, so it is necessary to ensure that the door body is in the closed state so that it does not operate as a hinged door in such a case. It is required to keep it in place.

In order to meet such demands, locking devices for hinged doors have been proposed.

For example, a locking device for a hinged door disclosed in Japanese Patent Application Laid-Open No. 57-151779 has a hole provided in the door body that fits into a support pin provided in a door wheel mechanism for opening and closing the door body. The weight of the door body is supported by the support pin, which prevents the free end of the door body from sagging, and the vibration that occurs when opening and closing the door body as a sliding door causes the hole in the door body to separate from the support pin, causing the door body to In order to prevent the door from being opened as a hinged door, a crank ratchet mechanism 71 is interposed between the door wheel mechanism and the door body, and this crank ratchet mechanism is inserted between the door wheel mechanism and the door body.
The mechanism used to hold the door body in a closed state by operating it as a hinged door.

However, the conventional locking device for swinging doors described above has a complicated structure such as a crank ratchet mechanism and requires a relatively large installation space. If it is not built-in, it will become thick and cause problems in appearance and use.2.It has the drawbacks of being heavy and having a value of 1rfJ.

This invention was made in order to improve the drawbacks of the conventional technology.Compared to the conventional technology described above, the structure is simpler and lighter, and even if it is built into the door body, the thickness of the door body does not become too thick. To provide an inexpensive locking device for a hinged door that does not require a large installation space.

A technical means for achieving this purpose is to open either a perforated shrine or a protruding member that is fitted into and removed from the hole of the perforated part and that is engaged with the hole in the fitted state to open the door. Mechanism
An elastically removable engagement that is provided on the door body of the sliding door and that is engaged with the protruding member that is fitted into and removed from the hole in the perforated part shrine in the turning direction in which the door body operates as a swinging door. This is because a mechanism has been established.

According to this technical means, one of the perforated part 4A and the protruding member is provided on the door body, and the other is provided on the fixed side, for example, the door i mechanism 4j. 0
The disadvantage of 1n can be solved.

In other words, it uses a perforated part and a protruding part +J instead of using a rank ratchet mechanism, which has a complicated structure like the conventional one, so the structure is simple and the installation space is small, and it can be built into the door body. Even if the door body is not built-in, the thickness of the door body is not so thick, there is no problem in appearance or use even when the door body is not built-in, and it is lightweight and can be manufactured at low cost. According to the above technical means, when the protruding part is fitted into the hole of the perforated part, the protruding part engages with the hole in the vertical direction, thereby reducing the weight of the door body. will be supported, and the door body 1 will not sag. In addition, in the above-mentioned mated state, the engagement mechanism prevents the door from operating as a swinging door and prevents the door from opening, creating a dangerous situation when the door opens as a swinging door. It does not produce any results.

Embodiments of the present invention will be described below with reference to the drawings.

The door body A of the swinging door mechanism (=J sliding door) illustrated in FIG. The passage section 2a can be opened and closed by being operated as a sliding door between the section 2b and the passage section 2a. It is superimposed on the door body B, which is attached to the frontage 2, and is rotated horizontally together with it to open and close as a hinged door.
It has a configuration that allows it to be fully opened.

Furthermore, details of the sliding door will be explained based on FIG. 2.A rail 3 is installed horizontally above the frontage 2, and a door roller mechanism 4 is supported on this rail 3 so as to be able to move forward and backward. In the illustrated example, the door roller mechanism 4 includes a pair of left and right hangers 4a provided with running wheels.

A hanging frame 4b is provided horizontally between 4a. Further, this door wheel mechanism 4 is connected to an endless traveling mechanism 5, and is configured to travel in the forward and reverse directions together with the endless traveling mechanism 5 by the forward and reverse driving of the door engine 6.

On the other hand, the door body A has a vertical shaft 8 provided at the top of one end.
When the support 4 is suspended from the suspension frame 4b of the second mechanism 4, the guide 1 is installed on one end of J(!f1(a)).
A cola 1] is movably locked on a guide rail 10, and the sliding door is opened and closed as a sliding door without causing lateral vibration by the forward and reverse movement of the door mechanism 4.

In addition, the upper part of the free end of the door body A, the suspension frame of the door wheel mechanism 4, and the I
A door locking device 100 is interposed between the opening door and the opening door locking device 100, which will be described further below.

On the other hand, the door pocket part 2b, σ door body B has one end upper part and -
1'lf:I It is constructed so that it can be opened and closed as a hinged door by means of a bearing mechanism 12 and a bottle provided at the lower part thereof, but normally it is kept in the closed state by a lathe 14 so that it does not open.

Next, the hinged door locking device 100 will be explained.

The hinged door locking device 100 illustrated in FIG. 3 includes a protrusion as a protrusion +A110 fixed to the door body Δ side,
It consists of a perforated part kA120 fixed to the hanging frame 4b side of the door roller mechanism. To explain specifically, the protrusion R1 (Shrine+1(N
The support fitting 130 is integrally fixed to a support fitting 130 made of L-shaped steel, and the support fitting 130 is inserted into a recess A formed on the upper edge of the free end of the door body A. ing.

Also, prominence i? The lI moon 110 is formed into a cylindrical shape, and is provided with an annular V-groove 111 at one location on its outer periphery as shown in FIGS. 4 and 5. On the other hand, the perforated part + Al
2O, the flanges at both ends thereof are attached to the lower surface of the hanging frame 4b by means of mounting bolts 140.
It is formed into a circular shape having approximately the same diameter as the outer circumferential diameter of 110. In addition, the perforated portion JA' 120 has one hole 122, 12 on both the left and right sides of the hole portion 121.
2 are formed, and an engagement mechanism 123 consisting of a plunger is fitted into each of these holes (=J holes 122).

The illustrated engagement mechanism 123 has a cylinder 123a with a built-in spring (not shown) and a spherical engagement claw 123b at one end.
is held, and the engaging claw 123b is always elastically biased in the projecting direction by the spring, and in the "removed" state, the engaging claw 123b projects into the hole 121.

In the above, when the door body A operates as a hinged door and is closed, the protruding portion +A110 is fitted into the hole 121 of the perforated portion 120 as shown in FIGS. 3, 4, and 5. Ru. In this case, as is clear from FIG. Therefore, if the door body A is made parallel to the hanging frame 4b in this state, the free 6111 will not sag due to its own weight when the door body A is opened and closed as a sliding door.

Further, as is clear from FIG. 5, when the protruding member 110 is fitted into the rear part 121, the engaging claw 123b of the engaging mechanism 123 is fitted into the V groove 111 of the protruding member 110, and the protruding part +All0 is They are engaged in the direction of removal from the hole 121, that is, in the direction of rotation during opening of the door that operates as a hinged door. At this time, since the engaging claw 123b is elastically pressed against the protruding member 110, the V/V
1111 is exerted, and as a result, the supporting metal fitting 130 is inserted into the perforated portion +, ('120 as shown in FIGS.
It can be pushed as shown in the figure. Therefore, when opening and closing the door body A as a sliding door, the door body A is reliably prevented from being opened as a hinged door.

Further, when opening the door body A as a hinged door, the door body A is pushed in the turning direction at the time of opening. In this way, the protruding member 11
0 pulls out the engagement claw 123b of the engagement mechanism 123 from the hole 121 while retreating against its elastic biasing force, and as a result, the door body A moves against the vertical shaft 8 and the guide roller 9 explained in FIG. It rotates around and opens.

Furthermore, when the door body A is operated as a hinged door to close it, the protrusion 91H material 110 is pushed toward the door body in the direction of rotation during closing movement around the vertical shaft 8 and guide roller 9 explained in FIG. Hole 01 (44'I) Fits into hole 121 of 20. That is, as shown by the imaginary line in FIG.
The protruding member 110 is pushed into the hole 121 as shown by the arrow from the state where the protruding member 110 is near its closed position 14 . In this way, the protruding members 1] and 0 are fitted into the holes 12 and supported by the holes 121, as shown by solid lines in the figure. at the same time,
As shown in FIG. 5), the engaging claw 123b of the engaging mechanism 123 fits into the V-groove 1], 1 of the protruding member 110, thereby preventing the door body A from opening. Note that the protruding member 110 is connected to the hole 12.
1, the free end of door body A hangs down (
Even if the parallelism with the hanging frame 4b is not maintained, the protruding member 11
Since the outer periphery of the tip of the protruding member 11 is a tapered surface 112, this tapered surface 112 comes into contact with the periphery of the hole 121 and acts as a guide surface.
0 is securely fitted into the hole 121. In the above, if the engagement mechanism 123 is screwed into the J hole 122, increasing or decreasing the amount of screwing in will increase or decrease the engagement, and the engagement force between the claw 123b and the protruding member 110. It has the advantage of being able to steplessly reduce J1/1 by 8111 nodes.

In the hinged door locking device 100 described in FIGS. 3 to 5, the protruding member 110 is provided on the door body A side, and the perforated portion 120 is provided on the hanging frame 4b side, but this point is Of course, the protruding member may be provided on the hanging frame and the perforated portion may be provided on the door body side.

Now, the locking device +00 for a hinged door is taken with its protruding part 0 accommodated in the recess A1 formed in the door body △, but this point is shown in Fig. 6. Even if it is attached so that it protrudes from the door body A, the same effects as those described above will be produced.In that case, the removal (=
i 4 () 1; The structure is, for example, as shown in the same figure, by drilling the door body A ('J'('L I 50) and inserting this mounting hole 15.
Take the proximal end of the protruding member 110 inserted through 0 (=J
It is fixed to the door body A using a pole l-151, a holding member 152, 153, etc.

In this way, when the protruding member 110 is protruded from the door body A (=J), the above-mentioned recessed part Δ1 (
There is no need to form a hole (see Figures 3 to 5), and it is sufficient to simply drill a hole 150 for the hole 150.
H is easy. In addition, since the protruding member 110 is extremely small compared to the door body A, even if the protruding member 110 protrudes from the door body A, it is not so noticeable, and the appearance and appearance are improved.
There is no decrease in usability.

FIG. 7 shows that the protruding member 110 has a rectangular prism shape, and the shape of the hole 121 of the perforated portion 120 into which the protruding member 110 is inserted and removed is rectangular. This also provides the same effects as those explained with reference to FIGS. 3 to 5.

In addition, in FIGS. 6 and 7, for convenience of explanation, elements corresponding to those explained in FIGS. 3 to 5 are designated by the same reference numerals, and their explanations are omitted.

Above 8゛r: As mentioned above, according to the present invention, the structure of the locking device for a hinged door is reduced in pH and is made smaller and lighter, so it can be easily removed even for a thin door body. ” can be removed. It also leads to lower prices. Despite this, the function of preventing the free end of the door body from sagging and the function of preventing the door body from opening accidentally as a hinged door work as reliably as conventional ones, and exhibit excellent effects. do.
