Description

  The present invention relates to a sliding door door installed in a building opening such as a building entrance.

Conventionally, a sliding door type automatic door that automatically slides an open / close door when a person or an object is detected at a building entrance is known (for example, see Patent Document 1).
As disclosed in Patent Document 1, a general automatic door has an open / close door that is opened and closed by a drive unit and a fixed plate that is provided in parallel with the open / close door. The fixed plate is fixed, and the building doorway is opened by moving the open / close door along the fixed plate. Such an automatic door is known as a sliding door type automatic door. Further, the fixed plate is made of the same glass material as that of the open / close door, so that a feeling of opening can be obtained.

As disclosed in Patent Document 1, when the opening / closing door is opened and moved, if there is a person or an object in the moving area of the opening / closing door, there is a risk that the opening / closing door may collide with the person or the object. Therefore, in the conventional automatic door 60 shown in the example of FIG. 24, a guard fence 62 is provided at a position separated from the fix plate 61, and the open / close door 6 is provided between the fix plate 61 and the guard fence 62.
By adopting a configuration in which 3 is moved, occurrence of problems is prevented.

With regard to this point, in Patent Document 1, it is said that the installation of the protective fence has a design and cost problem, and a detection sensor for detecting the entry of the object into the moving area of the open / close door is provided, and at the time of detecting the object By reducing the drive power to the drive unit, the above problem is solved.

Japanese Patent No. 3847621

However, in the configuration in which an object is detected by a detection sensor as in Patent Document 1, the detection (recognition) of an object varies depending on the height, approach speed, reflection characteristics, and the like of the object to be detected. There is concern. If the presence of an object is not detected, the moving opening / closing door may collide with a person or an object. Regarding detection of this object, even in a detection sensor that detects an object for opening and closing the open / close door, the open / close door does not open due to variations in detection, and the detection sensor is made to recognize the presence by moving the body. There are many people who have experience. In this way, in the configuration in which the presence of an object in the moving area of the open / close door is detected by the detection sensor, variation in detection (recognition) of the detection sensor may occur, and thus a new configuration that does not use the detection sensor Was desired.

Further, in the configuration of Patent Document 1, there is a concern that the detection (recognition) of an object cannot be accurately performed due to a failure of a detection sensor, contamination of the sensor light emitting unit / light receiving unit, or the like, and periodic maintenance is necessary. Therefore, a new configuration that does not use a detection sensor has been desired.

On the other hand, in the structure using the conventional guard fence, since the guard fence is fixed to the floor, it becomes difficult to clean the moving area of the open / close door. In the example of FIG. 24, since the protective fence 62 having a substantially L shape in plan view is fixed to the floor surface 64, it becomes difficult to clean the floor surface 64a inside the protective fence 62. Further, in the configuration in which the protective plate 65 is arranged like the protective fence 62, it is necessary to insert a nozzle of a vacuum cleaner or the like through a slight gap 67 between the protective plate 65 and the floor surface 64. If this gap 67 is not formed, it is necessary to insert a nozzle of a vacuum cleaner between the upper frame 68 of the protective fence 62 and the fix plate 61.

Further, in the case of the guard fence 62 as shown in FIG.
When a person sits down or puts an object, there is a possibility that the open / close door 63 may collide with them, so a new offensive capable of improving this has been desired.

Further, in the case of the protective fence 62 as shown in FIG. 24, the protective fence 62 is disposed outside the range of the frame prospect 69 of the automatic door 60, so that it cannot be installed in a place where the installation space cannot be secured. turn into. Even if the installation space can be secured, the presence of the protective fence 62 reduces the indoor space that can be freely used.

Therefore, in view of the above problems, the present invention proposes a configuration of a novel protective body used for a sliding door type door.

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

Next, embodiments of the invention will be described using examples. In the following description with reference to the drawings, for the sake of convenience, the upper side of the page will be described as the upper side, the lower side of the page as the lower side, the left side of the page as left and the right side of the page as the right.

As shown in FIG. 1 (a), the sliding door 1 is installed in the building opening 10, and the building opening 10 can be opened / closed by sliding the door 2 horizontally. It has become. Further, a drive unit 3 is provided on the upper part of the sliding door 1, and the open / close door 2 is slid in the horizontal direction by a drive device (not shown) provided in the drive unit 3. The drive unit 3 is provided with a detection sensor 4. When the human body is detected by the detection sensor 4, the opening / closing door 2 slides to open the building opening 10. ing. Note that the detection sensor 4 can be provided in various places such as a ceiling in addition to providing the drive unit 3 invisible as in the present embodiment.

Further, as shown in FIG. 1 (a), the sliding door type door 1 is provided with a fixed plate 5, and a range of about half of the width direction of the building opening 10 by the fixed plate 5 (left half in the figure). Is supposed to be closed. Further, the fixed plate 5 is a fixed member that does not slide, and the open / close door 2 slides along the fixed plate 5. The sliding door type door 1 with a single opening is configured in such a configuration.

Further, as shown in FIG. 1A, the sliding door type door 1 is provided with a protective body 6 that is spaced from and faces the fixed plate 5 and is disposed so as to retract the open / close door 2 between the fixed plate 5. It has been. The protective body 6 of this embodiment has substantially the same width and height dimensions as the fixed plate 5, and substantially the entire opening / closing door 2 is accommodated between the fixed plate 5 and the protective body 6. And
As a result, a door pocket is formed by the fixed plate 5 and the protective body 6. And
Thus, by providing the protective body 6, the moving region 7 of the open / close door 2, that is, the fix plate 5 is provided.
The area into which the opening / closing door 2 enters when the opening / closing door 2 opens is closed by the protective body 6. And the malfunction which a person and an object approach into this movement area | region 7, and collides with the opening / closing door 2 is prevented, and safety | security can be ensured now.

Further, as shown in FIG. 1 (a), in this embodiment, the open / close door 2 and the fix plate 5 are constituted by glass doors that surround the four sides of the glass plate with a frame, and similarly, the protective body 6 is also a glass door. It is supposed to be composed. According to this, in the normal time shown in FIG. 1A, the outdoor space (or indoor space) can be visually recognized through the protective body 6 and the fixed plate 5, and almost the entire range of the building opening 10 is made of glass. It will be partitioned by, and a high open feeling will be obtained. Further, even when the open / close door 2 is fully open, the outdoor space (or indoor space) can be visually recognized through the protective body 6, the fixed plate 5, and the open / close door 2, and a high feeling of opening can be obtained. Become.

Further, when the fixed plate 5 is formed of a glass door as in the present embodiment, it is mistaken that the fixed plate 5 is opened, and a person enters the moving area 7 and opens and closes at that time. Since the door 2 may be opened, in particular, when the fixed plate 5 is configured by a glass door,
The installation of the protective body 6 is effective.

In the sliding door type door 1 shown in FIG. 1 (a), the height of the plate surface of the protective body 6 is substantially the same as that of the fixed plate 5, and the entire movement area 7 of the open / close door 2 is closed by the protective body 6. However, the height of the plate surface of the protective body 6 is, for example, half the height of the fixed plate 5 to reduce the cost, and the hand is placed on the back side of the protective body with the hand naturally lowered. Increase the prevention of insertion by setting the height so that it is difficult to insert (for example, 90 cm to 140 cm), or set the height of the protector 6 higher than 110 cm so that the child's hand does not reach It is also possible to design such that it is difficult to hang. Moreover, when covering a part of the movement area | region 7 with a protective body in this way, it is good also as providing a lattice frame etc. in parts other than the board surface in a protective body.

Further, the positional relationship between the fix plate 5 and the protective body 6 shown in FIG. 1A is not particularly limited, and the fix plate 5 may be the outdoor side, the protective body 6 may be the indoor side, and vice versa. It is not something. In addition, the open / close door 2, the fix plate 5, and the protective body 6 are all configured with glass doors, and some or all of them may be configured with shielding doors, and the design of each door is particularly limited. It is not a thing.

Further, as shown in FIG. 1B, the upper frame 6 a of the protection body 6 can be slid in the horizontal direction while being suspended by the drive unit 3. Thereby, when necessity arises, such as at the time of maintenance of the sliding door type door 1, the protective body 6 can be slid in the horizontal direction, and the moving area 7 of the opening / closing door 2 formed between the fixed plate 5 and the protective body 6. Is released, and this moving area 7
Can be easily cleaned.

With the above configuration, as shown in FIG. 2, when normally closed and normally opened, the protective body 6 is disposed at a position facing the fixed plate 5 to form a door pocket 9. Therefore, it is possible to prevent a person or an object from entering the moving area 7 of the open / close door 2. And
At the time of maintenance, the moving area 7 is opened by sliding the protector 6 to the right in the figure, and the floor surface of the moving area 7 and the inner surface of the fixed plate 5 (on the side of the open / close door 2). It is possible to clean the surface). Further, by sliding the open / close door 2 to the left in the figure, it is possible to clean the inner surface of the protective body 6 (the surface on the open / close door 2 side).

Next, the detail of each part of the sliding door type door 1 is demonstrated.
FIG. 3 is a longitudinal sectional view showing the configuration of the sliding door type door 1, and FIG. 4 is a transverse sectional view showing the configuration of the sliding door type door 1.
As shown in FIGS. 3 and 4, in this embodiment, the sliding door 1 is provided at the indoor / outdoor entrance of the building, the fixed plate 5 is disposed on the outdoor side, and the protective body 6 is disposed on the indoor side,
An opening / closing door 2 is arranged.

Further, as shown in FIG. 3, the drive unit 3 is disposed on the upper part of the sliding door 1, and the fixed plate 5, the opening / closing door 2, and the protective body 6 are parallel between the drive unit 3 and the floor surface 11. It is provided and the indoor / outdoor space is partitioned by these doors.

As shown in FIGS. 3 and 4, the fix plate 5 includes an upper frame 5 a (FIG. 3) and a lower frame 5 b (
3), a glass door is configured so as to surround the glass plate 5e by the vertical frames 5c and 5d (FIG. 4), and the upper frame 5a and the lower frame 5b are respectively connected to the drive unit 3 and the floor surface 11. It is fixed.

As shown in FIGS. 3 and 4, the open / close door 2 includes an upper frame 2a (FIG. 3) and a lower frame 2b (FIG. 3).
), The glass door is configured so as to surround the glass plate 2e by the vertical frames 2c and 2d (FIG. 4). Further, the upper frame 2 a of the open / close door 2 is connected to a drive device 12 installed in the unit case 3 a of the drive unit 3, and the open / close door 2 is slid by the drive device 12.

As shown in FIG. 3, the lower frame 2b of the opening / closing door 2 is formed with a substantially gate-shaped groove rail portion 2m for accommodating a guide roller 25 protruding upward from the floor surface 11, and the opening / closing door is formed. When 2 slides, the vertical wall surface of the groove rail portion 2m comes into sliding contact with the guide roller 25, and
At this time, the guide roller 25 is configured to rotate around a vertical rotation axis.
With this configuration, the open / close door 2 is slid by the driving device 12 while its lower frame 2 b is guided by the guide roller 25. As shown in FIG. 5 (a), a guided shaft 2f is projected downward on the lower frame 2b of the opening / closing door 2, and the guided shaft 2f is guided with respect to the guide groove rail 8 provided on the floor surface 11. By adopting a configuration that inserts
The lower frame 2b may be guided along the guide groove rail 8.

Further, as shown in FIGS. 3 and 4, the protective body 6 includes an upper frame 6a (FIG. 3) and a lower frame 6b (FIG. 3).
The glass door is configured so as to surround the glass plate 6e by the vertical frames 6c and 6d (FIG. 4). Further, the upper frame 6 a of the protection body 6 is suspended from a guide rail 3 b installed in the unit case 3 a of the drive unit 3 via a suspension type moving mechanism 13 so as to be slidable.

As shown in FIG. 3, a shaft-like stopper member 6 f is provided on the lower frame 6 b of the protection body 6 so as to protrude and retract in the vertical direction, and this stopper member 6 f is formed on the floor surface 11. It can be inserted into and removed from the floor hole 8a in the vertical direction. When the stopper member 6f is inserted into the floor hole portion 8a, the sliding movement of the protective body 6 is restricted by the engagement of the stopper member 6f and the floor hole portion 8a, and the stopper member 6f is removed from the floor hole portion 8a. In the case of
The sliding movement of the protective body 6 is allowed. With this configuration, under normal conditions,
By fixing the stopper member 6f in a state of being inserted into the floor hole portion 8a, it is possible to realize a fixed state in which the sliding movement of the protective body 6 is restricted. On the other hand, at the time of maintenance, by fixing the stopper member 6f to the position extracted from the floor hole portion 8a, it is possible to realize a fixed release state in which the sliding movement of the protective body 6 is allowed. The specific configuration for fixing / unlocking the protective body 6 is not particularly limited. For example, a configuration in which a French drop is installed on the protective body 6 to fix / unfix the floor 6 or the suspension is suspended. A configuration in which the moving mechanism 13 is fixed / unfixed to / from the guide rail 3b can be applied.

Further, in the configuration of the protective body 6 shown in FIG. 5A, a gap is formed between the lower frame 6b of the protective body 6 and the floor surface 11 in a state where the stopper member 6f is accommodated upward, and the protective body 6 6 is configured such that the lower frame 6b is not particularly guided during sliding movement.
As shown in the configuration of b), the guided shaft 6g protrudes downward from the lower frame 6b of the protective body 6, and the guided shaft 6g is inserted into the guide groove rail 88 provided on the floor surface 11. It is good also as a structure by which the lower frame 6b is guided along the guide groove rail 88 by setting it as a structure.
Further, as shown in FIG. 5C, the lower frame 2b of the open / close door 2 and the lower frame 6b of the protective body 6 may be guided by the guide rail grooves 8 and 88, respectively.

As shown in FIG. 3, the suspension type moving mechanism 13 is for sliding the protective body 6 along a long guide rail 3 b provided in the horizontal direction in the unit case 3 a of the drive unit 3. It is. In the present embodiment, the suspension type moving mechanism 13 includes the guide rail 3b.
A roller member 14 that rotates on the ridge 3c of the ridge, an upper stay 15 that rotatably supports the roller member 14, and a lower stay 16 that connects the upper stay 15 and the upper frame 6a of the protection body 6. It consists of and.

Moreover, as shown to Fig.6 (a), the suspension type moving mechanism 13 is provided in two places (it may be two or more places) in the width direction (movement direction of the protection body 6) of the protection body 6, As a result, the protective body 6 is supported in at least two places in the width direction of the protective body 6, and FIG.
(A) As shown in (b), the protective body 6 can be slid and moved while keeping the horizontal state of the protective body 6.

In addition, as shown in FIG. 3, in the suspension type moving mechanism 13, when the protective body 6 slides, the roller member 14 rotates, so that the protective body 6 can be moved with a light force. Thus, the workability when changing the position of the protective body 6 during maintenance can be improved. Further, the protective body 6 is a suspension type moving mechanism 13 (roller member 14).
), The sliding body can be slid with a light force without feeling the weight of the protective body 6, and the workability is improved. In particular, when the protective body 6 is composed of a glass door, the effect is great.

Further, as shown in FIG. 3, during maintenance, maintenance of the drive device 12 and the like can be performed by removing the case cover 3 d constituting the finding surface of the drive unit 3 from the unit case 3 a. Further, as shown in FIGS. 6A and 6B, during the maintenance, the protective body 6 is appropriately slid to shift the position of the suspension type moving mechanism 13 so that the driving device 12 and the control devices 17 and 18 are moved. It is possible to reach a state where the hand can reach. Thus, the structure excellent in maintainability is realizable by making the protection body 6 into the structure which can be slid. In view of this maintenance, as shown in FIG. 3, the guide rail 3b is Ru is installed at a position higher than the maintenance object such as drive 12.

In addition, instead of the form of sliding the protective body 6 as shown in FIGS. 6 (a) and 6 (b),
By supporting the upper frame and lower frame of the protective body with a rotating shaft, it is conceivable that the protective body is in the form of a one-sided hinge door. In this case, a bearing portion for rotating and supporting the protective body is provided in the drive unit. In addition, it is conceivable that the bearing portion has a high rigidity, and the presence of the bearing portion obstructs the maintenance of the drive device. Also from these viewpoints, the form in which the protective body 6 is slid as in this embodiment is excellent in maintainability.

Further, as shown in FIGS. 3 and 4, the protective body 6 is supposed to be accommodated within the range of the frame prospect 20 of the sliding door 1. In this embodiment, the frame constituting the outer periphery of the sliding door 1 is composed of a unit case 3a (FIG. 3) of the upper drive unit 3 and frame members of the vertical frames 21 and 21 (FIG. 4). The protective body 6 is accommodated within the range of the frame prospect 20 which is the depth dimension of these frame members, and the protective body 6 is configured to be slidable within the range of the frame prospect 20. . Similarly, the fix plate 5 and the open / close door 2 are configured to be within the range of the frame prospect 20.

With this configuration, as shown in FIGS. 3 and 4, in installing the sliding door type door 1, it is sufficient to secure only the dimension of the frame prospect 20 as an installation space. Thereby, it becomes possible to utilize effectively spaces other than the space where the sliding door type door 1 is installed. For example, it is possible to place an object in the space 22 facing the protective body 6 and to secure a wide width when the space 22 becomes a passage. At the time of maintenance, since the protective body 6 is slid and moved, the protective body 6 does not enter the space 22 facing the protective body 6, so there is no need to move the object, and the passage width, etc. It is possible to perform maintenance work in a state where is maintained.

Next, the retracting prevention structures 30 and 40 shown in FIG. 7 will be described.
The retracting prevention structures 30 and 40 are configured such that an object and a part of a human body (such as fingers) are opened and closed between the opening and closing door 2 and the protective body 6 and between the opening and closing door 2 and the fixing plate 5. 2 is provided to prevent the door 2 from being pulled into the door pocket 9 (see FIG. 2) (moving region 7 (see FIG. 2)).

Although it is well known that measures against pulling in such objects and parts of human bodies (such as fingers) are applied to automatic doors of trains, they are applied to automatic doors of buildings such as buildings and houses. Has not been. As for the application to the automatic door of the train, measures are taken on the assumption that people are leaning on due to the limited space in the vehicle, but the automatic door of the building is different from the environment in the vehicle, It is thought that no measures were taken because people could move freely.

However, it is also desirable to take measures to prevent retraction in automatic doors installed in buildings. However, when considering the structure of an automatic door installed in a building, there is nothing that can prevent the pull-in by a uniform design unlike an automatic door of a vehicle. That is, in automatic doors of buildings, the thickness of the opening and closing doors varies depending on the construction location, such as single glass door, pair glass door, soundproof glass door, etc. It differs depending on the construction location, and on-site adjustments such as narrowing the frame prospect according to the installation space are required. As described above, it is not easy to realize the anti-retraction measures for the automatic door installed in the building in consideration of the current state of the construction.

Further, in this embodiment, as shown in FIG. 7, in addition to the conventional measures for preventing the pull-in between the opening / closing door 2 and the fixed plate 5, the opening / closing door 2 and the protection body 6 provided with the protection body 6 It is desirable to take measures to prevent entrainment between

Therefore, in view of the above problems, as shown in FIG. 7, the anti-retraction structures 30 and 40 are provided.
First, the retracting prevention structure 30 provided on the protective body 6 side will be described. A long attachment frame 31 that is long in the vertical direction is fixed to the vertical frame 6 d of the protective body 6 by a fixing tool 37. In the attachment frame 31, a long packing member 32 that is long in the vertical direction is fitted on the side facing the opening / closing door 2. Further, engaging portions 33 and 33 projecting in the left-right direction in the figure are formed at portions of the packing member 32 that are inserted into the attachment frame 31, and the engaging portions 33 and 33 are formed in the attachment frame. It is adapted to be engaged with engaged portions 34, 34 that are formed on the inner wall surface of 31 and are long in the vertical direction.

Further, as shown in FIG. 7, the engaged portions 34, 34 are formed at a plurality of locations in the expected direction (thickness direction of the protective body 6), so that the packing member 32 protrudes from the attachment frame 31. The amount can be changed, whereby the gap 35 between the protruding end 32a of the packing member 32 and the surface of the glass plate 2e of the open / close door 2 can be adjusted.

Further, as shown in FIG. 7, since the glass plate 2e exists at a position deeper from the lower frame 2b of the open / close door 2, it is necessary to install the packing member 32 at a position higher than the height of the lower frame 2b. For this reason, in the present embodiment, the lower closing member 36 having a height substantially equal to the lower frame 2b of the opening / closing door 2 is inserted into the lower portion of the attachment frame 31 so that it is positioned higher than the lower frame 2b of the opening / closing door 2. The packing member 32 is arranged. Attachment frame 31
Similarly, the closing member is inserted in the upper part of.

Further, as shown in FIG. 7, the packing member 32 is made of a material such as flexible rubber or resin, and even if a finger or the like is likely to be drawn, the packing member 32 is bent. As a result, a time margin for releasing the hand from the open / close door 2 is created, and the hand can be released from the open / close door 2. Furthermore, in the packing member 32, by providing a long cavity portion 32b in the vertical direction, the above-mentioned time margin can be further ensured by increasing the flexibility.

As described above, as shown in FIG. 7, the pull-in prevention structure 30 is configured between the open / close door 2 and the protective body 6, and measures for preventing the pull-in between the open / close door 2 and the protective body 6 can be achieved. . Then, by appropriately adjusting the gap 35 by appropriately changing the amount of protrusion of the packing member 32 in the situation of the construction site, it is possible to take an optimal pull-in prevention measure according to the situation of the construction site.

Similarly, as shown in FIG. 7, a pull-in prevention structure 40 is configured between the open / close door 2 and the fixed plate 5. Here, the pull-in prevention structure 40 can be attached later to the existing fix plate 5. That is, as shown in FIG.
The attachment frame 41 and the packing member 42 are provided, and the attachment frame 41 is fixed to the vertical frame 5d with a fixture 47 by a retrofit. In this way, it is possible to install the pull-in prevention structure 40 later. Further, as can be seen from this example, it is also possible to install the pull-in prevention structure 40 on an existing automatic door as a retrofit.

In FIG. 8, the lower closing member 46 is attached to the attachment frame 41 by a fixture 48.
It is fixed to. Also in the anti-retraction structure 40, the anti-retraction structure 3
Similarly to 0, by changing the engagement position of the engagement portions 43 and 43 of the packing member 42 with respect to the engaged portions 44 and 44, the protruding amount of the packing member 42 having the cavity portion 42b can be changed. . The other functions of the pull-in prevention structure 40 are the same as those of the pull-in prevention structure 30.

The above is the configuration of the first embodiment.
That is, as shown in FIG.
A sliding door type door 1 having a sliding door type opening and closing door 2,

As shown in step F of FIG. 20, the assembly of the protective body 106 is completed, and FIG.
As shown in FIG. 8, the protective member 106 is moved by the movement restricting means 190 to the horizontal portion 1 of the frame member 181.
By engaging with 81b, the movement of the protective body 106 can be restricted.

And since the operation | work of the assembly | attachment of the protective body 106 shown by FIG.19 and FIG.20 demonstrated above is a simple work content, workability | operativity will become a very favorable thing. Sliding door type door 2
In the case of newly installing 00, the unit frame 210 and the locked member 220 are integrated in advance, so that at the construction site, the work is completed only by installing the floor side guide member 111n and assembling the protective body 106. can do.

Further, when the protective body 106 is installed on the existing sliding door type door 200, fixing the locked member 220 to the unit frame 210, installing the floor surface side guide member 111n, and assembling the protective body 106 are simple. Can be done by work. That is, it is possible to easily retrofit the protector 106 to the existing sliding door type door 200 in a short period of time, and as a result, it is extremely feasible as a form of safety measures for the existing sliding door type door 200. High configuration. Also,
As shown in FIGS. 13 and 14, the nut member 183 c and the bolt member 184 c that can be turned by hand without using a tool are compared with the case of working with a tool. As a result, the assembling work of the protective body 106 can be carried out easily in a shorter time. Further, regarding the fixing of the locked member 220 to the unit frame 210, the locked member 22
If a hole for inserting the bolt member 220b (see FIG. 13) is formed in advance at 0, a cut hole or the like can be processed on the unit frame 210 side using this hole as a guide. In addition, the measuring work for the hole processing in the unit frame 210 can be made unnecessary.

Further, as shown in FIG. 10, when the protective body 106 is installed on the existing sliding door type door 200, in the configuration of the second embodiment, the weight of the protective body 106 is the support means 170 (the door wheel 17.
1), the load of the protective body 106 is not applied to the locked member 220 on the unit frame 210 side. For this reason, the unit frame 210 is not required to have a special strength, and in particular, the existing sliding door type door 200 can be installed afterward without being limited by the weight of the protective body 106. It becomes possible to do.

Further, the assembling of the protective body 106 shown in FIGS. 19 and 20 is performed by raising the protective body 106 vertically from an inclined state, but other forms are also conceivable. For example, as shown in FIGS. 13 and 21, the second rail portion 182c in the connecting means 182 is pulled out from the first rail portion 182a and separated, and the second rail portion 182c is separated from the upper frame 1.
On the other hand, the frame member 181 and the first rail portion 182a of the connecting means 182 are locked to the locked member 220 side while being integrated with 06a. In this state, the protective body 106 is moved to the open / close door 1.
02, by inserting the second rail portion 182c into the first rail portion 182a,
The protective body 106 can be installed by assembling the protective body 106 to the connecting means 182 (first rail portion 182a) and the frame member 181.

Next, as shown in FIG. 22, the following property of the protective body 106 with respect to the gradient and unevenness of the floor surface 111 will be described.
As shown in FIG. 22, during the maintenance, the protector 106 is moved from the position PA to the position P.
Slide to B.
In this case, at the construction site where the protective body 106 is installed, there are cases where the floor surface 111 is uneven, or there is a gradient M with respect to the horizontal level L in the sliding direction of the protective body 106. In the thickness direction of the protective body 106, the horizontal level L
There may also be a gradient N for. In such a case, the door wheel 171 goes up the floor surface 111 along the gradient M. In this process, if there is unevenness, the door wheel 171 moves up and down, and the door wheel 171 also moves up and down unstablely due to the gradient N.

In this regard, in the configuration of the second embodiment, the shaft portion 183a of the locking means 183 provided in the guide means 180 on the protective body 106 side is inserted through the notch 220a of the locked member 220 so as to be movable up and down. Therefore, even when a situation occurs in which the door wheel 171 moves up and down due to the gradient of the floor surface 111 or the like, the vertical movement of the upper frame 106a of the protective body 106 is not restricted. It is like that. Thereby, even when the door wheel 171 moves up and down due to the gradient or unevenness of the floor surface 111, the protective body 106 can be slid and moved without any problem. In other words, the protective body 106 as a whole is allowed to move up and down,
The protection body 106 is locked to the locked member 220 on the unit frame 210 side, and thus the protection body 106 can be moved up and down following the gradient of the floor surface 111 and the like.

Note that the floor surface 111 having a gradient as shown in FIG. 22 is a particularly common situation on the floor surface 111 of an existing building, and the protector 106 is installed on an existing sliding door door as a retrofit. In this case, as in the second embodiment, the followability to the gradient and unevenness of the floor surface 111 is important. In other words, according to the configuration of the second embodiment, it can be installed without any problem without selecting the situation of the floor surface 111 at any construction site, and the protective body 106
It is possible to realize a smooth slide movement.

The above is the configuration of the second embodiment.
That is, as shown in FIG. 9 and FIG.
