Description

The present invention relates to a door mounting structure for an automatic door device .

Conventionally, as automatic door devices, there are known a built-in type (kamoi) built-in type, an external kamoi type, and a ceiling-mounted type depending on a place where an automatic door driving device (door engine) is installed.
For example, Patent Document 1 discloses an automatic door device having a door mounting structure in which a door hanger (hanger metal fitting) that holds a suspended door pulley that is horizontally driven on a suspension door rail portion is fastened to an upper end edge of a sliding door door with a bolt. Are listed.
In such an automatic door device, since the sliding door type door and the door hanger are directly bolted (screw fastening), workability such as bolt attachment / detachment is poor, especially when installed on the back of the ceiling. There was a problem that work efficiency during maintenance was not good.
In order to improve such workability as much as possible, an automatic door device having a door mounting structure in which a door mounting member is provided between the door and the hanger bracket so that the door does not have to be directly operated. It has been known. For example, as a door mounting member, a hanger spacer with an H-shaped cross section in which two parallel flat plates are connected by a support plate is provided, and the upper flat plate and the hanger fitting are screw-fastened, and the lower flat plate is screwed to the door Is known. As the hanger spacer, there are known one in which two parallel flat plates and a support plate are welded, and one in which a similar shape is manufactured by casting.
In this case, by appropriately setting the height and shape of the hanger spacer, it is possible to secure a work space such as screw fastening or facilitate the work.

It is set as the structure which provided the plate nut member which has the some internal thread part to which the external thread for 1 attachment is fastened .
According to the present invention, since the female screw portion is provided in the plate nut member, the female screw portion of the door mounting member can be omitted or reduced, so that the configuration of the door mounting member can be simplified.

According to this invention, the door mounting member, since the connecting apart from the vertical direction and the first mounting portion and a second mounting portion by the support portion, the lower of the first mounting portion and second mounting An empty space can be formed above each part. Therefore, it is possible to secure a space for fastening the mounting male screw.
In addition, since the first and second attachment portions and the support portion are integrally formed by press working, the structure is inexpensive and highly reliable as compared with the case where the first and second attachment portions and the support portion are separately formed, for example, by welding. can do.

According to this invention, in a state of fixing the second mounting portion and the door portion, only loosening the mounting male thread for fixing the first mounting portion and the hanger bracket, the door with a fixed door mounting member The part can be removed.

According to this invention, only loosening the mounting male thread for attachment to the door unit, since the door mounting member can be removed from the door portion is pulled out in a horizontal direction, attachment and detachment of the door mounting member from the door portion It becomes easy.

In the present invention, the first attachment portion and the second attachment portion are integrally formed by bending in different directions with respect to the support portion .
According to the present invention, for example, even if a manufacturing error occurs in the bending angle due to variations in a mold or a plate material for bending the door mounting member, the manufacturing error is caused by the symmetry of the generation direction and the first mounting portion. The two mounting portions cancel each other, and the parallelism between the first mounting portion and the second mounting portion can be maintained with high accuracy.
In this invention, it is set as the structure by which the notch is each formed in the both sides of a horizontal direction in the said vertical board part of the said hanger metal fitting.

It is intended to be able to move smoothly.
The schematic configuration is such that a door wheel 4c is fitted to a hanger fitting 5 and a support shaft 4a erected in the horizontal direction on the hanger fitting 5 via a bearing 4b.
Hereinafter, for convenience of explanation of the direction, the direction facing the front of the building orthogonal to the rail 8 (left direction in FIG. 2), that is, the direction of viewing the back surface of the front panel portion 23 from the ceiling back 19 is the P direction. The reverse direction is referred to as the Q direction.

  As shown in FIG. 3, the hanger fitting 5 is arranged in a horizontal direction and extends horizontally in the direction along the rail 8 (see FIG. 1), and a horizontal plate portion 5 </ b> A (attachment portion of the hanger fitting). It consists of a vertical plate portion 5B erected vertically on the plate portion 5A. For this reason, as shown in FIG. 2, the cross-sectional shape of the hanger metal fitting 5 is such that the vertical plate portion 5B is arranged in parallel to the rail 8, and the horizontal plate portion 5A extends in the P direction below the rail 8. It has a letter shape.

U-shaped grooves 5a and 5a (U-shaped grooves) penetrating in the thickness direction for inserting hanger fixing bolts 16 and 16 (male screws for mounting) from above are provided at both ends in the longitudinal direction of the horizontal flat plate portion 5A. Is extended in the P direction from the inside of the horizontal plate portion 5A.
Further, the vertical plate portion 5B has notches 5b and 5b formed at both ends in the horizontal direction so that work in the vicinity of the U-shaped grooves 5a and 5a can be easily performed from the Q direction side.
On the lower surface side of the horizontal plate portion 5A, the hanger spacer 6 (door mounting member) is screwed with the hanger fixing bolts 16 and 16, and the door portion 2 is hung with the hanger spacer 6 screwed with the door suspension bolts 17 and 17. Has been lowered.

As shown in FIGS. 3 and 4, the hanger spacer 6 extends in a range substantially overlapping the horizontal plate portion 5A of the hanger fitting 5 and has a U-shaped upper mounting portion 6A (door mounting member) that opens in the Q direction in plan view. First mounting portion) and a U-shaped lower mounting portion 6C (second mounting portion of the door mounting member) that opens in the P direction in plan view are arranged substantially in parallel, and each U-shaped This is a member connected by a support plate portion 6B (support portion) that extends in the vertical direction between the recesses.
For this reason, when it sees from the direction where the rail 8 is extended, it has comprised H shape. 4B, the upper mounting portion 6A, the support plate portion 6B, and the lower mounting portion 6C constitute a Z-shaped (inverted Z-shaped in the drawing) cross section. .

In order to insert the hanger fixing bolt 16 and the door suspension bolt 17 in the vertical direction at both ends sandwiching the U-shaped opening of the upper mounting portion 6A and the lower mounting portion 6C, respectively, the Q direction, P U-shaped grooves 6a and 6a (U-shaped grooves) and U-shaped grooves 6b and 6b (U-shaped grooves) extending in the direction and penetrating in the thickness direction are provided.
The arrangement interval of the U-shaped grooves 6a and 6a is equal to the arrangement interval of the U-shaped grooves 5a and 5a, and the arrangement interval of the U-shaped grooves 6b and 6b is the arrangement interval of the female screws 18 and 18 provided at the upper end portion of the door portion 2. To be equal to each other.
Although the vertical positional relationship between the U-shaped groove 6a and the U-shaped groove 6b can be set as appropriate, in the present embodiment, the positional relationship is set such that the vicinity of each groove side portion substantially overlaps.

Therefore, as shown in FIG. 4 (b), it has an H-shape when viewed from the Q direction, and on both sides of the support plate portion 6B, there is a door between the upper mounting portion 6A and the lower mounting portion 6C. Mounting spaces 6c and 6c in which the suspension bolts 17 can be taken in and out are formed.
On the lower surface side of the upper mounting portion 6A, a plate nut 15 (plate nut member) having a U-shape in plan view having an opening for fitting the support plate portion 6B in the horizontal direction is disposed. The plate nut 15 is provided with a female screw 15a (female screw portion) for screwing the hanger fixing bolt 16 at a position where the U-shaped grooves 5a and 6a are overlapped.

The hanger spacer 6 may be manufactured by, for example, welding three metal plates respectively corresponding to the upper mounting portion 6A, the support plate portion 6B, and the lower mounting portion 6C. One metal plate having rigidity for holding the load of the portion 2, for example, a mild steel plate, a stainless steel plate, an aluminum alloy plate, or the like is formed by pressing. For example, SS400 having a plate thickness of 6 mm can be employed.
FIGS. 5A, 5 </ b> B, and 5 </ b> C are process explanatory views for explaining a part of the manufacturing process of the door mounting member according to the embodiment of the present invention. FIG. 6 is a cross-sectional view for explaining the manufacturing variation of the door mounting member according to the embodiment of the present invention.

In order to manufacture the hanger spacer 6 by press working, first, a workpiece 30 (see FIG. 5A) in which the outer shape and the shapes of the U-shaped grooves 6a, 6a, 6b, 6b are formed is formed by a punching process. . In the bending step, the boundary between the upper mounting portion 6A and the support plate portion 6B is bent to 90 °.
That is, a plate-like workpiece 30 is placed on a die 32 on which V-shaped mold surfaces 32 a and 32 a forming an angle θ ₀ are formed, and pressed by a punch 31, and the workpiece 30 is attached to the die 32. The workpiece 30A is formed by bending along the mold surface 32a. When the workpiece 30A is detached from the die 32, an angle change Δθ of the bent portion due to the spring back occurs, so that the angle of the bent portion is θ ₀ + Δθ. Since the die 32 is designed in consideration of Δθ, θ ₀ + Δθ = 90 ° can be set.
Next, the workpiece 30B is turned upside down and placed again on the die 32 to perform a bending process, and the boundary between the lower mounting portion 6C and the support plate portion 6B is directed in the direction opposite to the upper mounting portion 6A. Bend to °.
In this way, as shown in FIG. 6A, the hanger spacer 6 having a bent portion with an angle θ ₁ = 90 ° is formed.

By the way, it is also conceivable that the spring back amount Δθ changes due to the plate thickness variation of the workpiece 30 or the lot variation of the metal plate, resulting in a manufacturing error in the angle of the bent portion. For example, it is assumed that a bent portion of θ ₂ > θ ₁ is formed as shown in FIG. In this case, the support plate portion 6B is inclined with respect to the upper attachment portion 6A and the lower attachment portion 6C. However, since the mutual inclination angles are canceled due to symmetry in the inclination direction, the upper attachment portion 6A and the lower attachment portion 6B The parallelism with the mounting portion 6C does not change. Therefore, the door portion 2 can be suspended from the hanger spacer 6 without tilting due to the change in parallelism.

  According to such a configuration, the door suspension bolt 17 is inserted into the U-shaped groove 6b of the hanger spacer 6 from above, and is fastened to the two female screws 18 at the upper end of the door portion 2 so that the hanger spacer 6 is attached. Fix on the door 2. Then, the hanger spacer 6 and the hanger fitting 5 are overlapped by aligning the U-shaped groove 6a and the U-shaped groove 5a of the upper mounting portion 6A, and the hanger fixing bolts 16 are inserted into the U-shaped grooves so that the plate nuts are inserted. It is possible to construct a door mounting structure in which the door portion 2 is suspended from the hanger fitting 5 by being fastened to the 15 female screws 15a.

In such a door mounting structure, for example, during maintenance, the door portion 2 can be removed as follows.
FIG. 7 is a cross-sectional explanatory view in the same direction as FIG. 2 for explaining the door portion removing step in the door mounting structure according to the embodiment of the present invention.
The operator opens the inspection port 20 (see FIG. 2), enters the ceiling 19 and inserts a tool such as a wrench from the Q direction to loosen each hanger fixing bolt 16. As a result, the fastening between the hanger fitting 5 and the hanger spacer 6 is released.
Here, since the notch 5b is formed in the hanger metal fitting 5, the hanger fixing bolt 16 can be easily visually recognized from the Q direction, and a tool such as a wrench can be inserted through the notch 5b.
Next, if the hanger spacer 6 is moved in the P direction together with the door portion 2, the door portion 2 can be removed from the hanger fitting 5. For example, the door part 2 can be exchanged or maintenance inspection work can be performed.

In such a case, if the distance h between the horizontal plate portion 5A and the angle 22 is shorter than the length of the hanger fixing bolt 16, the hanger fixing bolt 16 can be pulled out only in the upward direction. Disappear.
According to the present embodiment, the hanger fixing bolt 16 is pulled out in the horizontal direction through the U-shaped groove 5a, and pulled out in the Q direction along the U-shaped groove 6a in a state of being detached from the hanger fitting 5, thereby forming a two-dot chain line. Can be removed as shown.
If it is necessary to leave the hanger fixing bolt 16 on the horizontal plate portion 5A, the hanger fixing bolt 16 is not moved, but only the hanger spacer 6 is pulled out from the hanger fixing bolt 16 in the horizontal direction and moved in the P direction. You can also.
If it is necessary to remove the hanger spacer 6 from the door portion 2, insert a wrench or the like in the P direction toward the mounting space 6c to loosen the door suspension bolt 17, and pull out the hanger spacer 6 in the Q direction. 6 can be removed from the door 2.
Further, by following the reverse process, the disassembled members can be reassembled.

Thus, in the door mounting structure of the automatic door device of the present embodiment, both the hanger fitting 5 and the hanger spacer 6 are horizontally oriented by loosening the hanger fixing bolt 16 by the action of the U-shaped grooves 5a, 6a, 6b. Therefore, at least one of them can be pulled out in the horizontal direction as necessary. Therefore, the hanger fitting 5 and the hanger spacer 6 can be easily attached and detached even when the work space is not sufficient in the vertical direction. Moreover, it becomes easy to remove the hanger fixing bolt 16, the door suspension bolt 17, and the like.
Thus, according to this embodiment, the workability at the time of attachment of the door part 2 or a maintenance can be improved.

  Further, since the hanger spacer 6 of the present embodiment is manufactured by pressing, unlike the case of manufacturing by casting or welding, for example, the hanger spacer 6 is inexpensive and does not cause casting defects such as nests, welding defects, welding defects, etc. There is an advantage that it can be manufactured with high accuracy.

Next, a modification of this embodiment will be described.
FIGS. 8A and 8B are cross-sectional explanatory views in the same direction as FIG. 6 for explaining a schematic configuration of an example of a door mounting member according to a modification of the embodiment of the present invention.
As shown in FIG. 8A, the hanger spacer 60 of this modification has a bending direction with respect to the support plate portion 6B corresponding to the upper mounting portion 6A and the lower mounting portion 6C of the hanger spacer 6 of the above embodiment. An upper mounting portion 60A and a lower mounting portion 60C are provided in the same direction. That is, a U-shaped cross section bent at an angle θ ₁ = 90 ° is formed by the upper mounting portion 60A, the support plate portion 6B, and the lower mounting portion 60C.

In this case, since the bending process can be made into one process by channel bending, it can be manufactured at low cost.
However, as shown in FIG. 8B, when the spring back varies, the influence is doubled in the same direction, so the parallelism between the upper mounting portion 60A and the lower mounting portion 60C varies. It is easy to come out. In such a case, it is preferable to perform management so that variations in springback are reduced.

In the above description, the U-shaped groove has been described as an example provided in each mounting portion of the hanger fitting and the door mounting member. However, for the purpose of removing the door portion, at least one door mounting member is mounted. It is only necessary to provide a U-shaped groove on the surface.
For example, a U-shaped groove may be provided only in the first attachment portion of the door attachment member, and a round hole or a long hole may be provided in the second attachment portion of the door attachment member.
Moreover, a U-shaped groove may be provided only in the second attachment portion of the door attachment member, and a round hole, a long hole, or a female screw may be provided in the first attachment portion. Here, when a female screw is provided, the plate nut member can be omitted.
Moreover, in any case, the hanger fitting may have any of a U-shaped groove, a round hole, or a long hole.

In the above description, when the hanger fitting and the door mounting member are fastened with screws, the example in which a plurality of female screws for fastening the mounting male screws are provided on the plate nut member has been described. In this case, there are advantages that the number of parts can be reduced and the mounting operation is facilitated, but the plate nut member is not limited to one in which a plurality of female screws are formed. For example, a plate nut member in which one female screw is formed corresponding to each male screw for attachment may be used.
Further, instead of the plate nut member, for example, a nut member such as a hexagon nut may be adopted.

  In the above description, the U-shaped groove has been described as an example of the U-shaped groove. However, if the U-shaped groove has a shape that can be pulled out in the horizontal direction with respect to the mounting male screw by having an opening at the end, It is not limited to a groove. For example, it may be a rectangular groove or a V-shaped groove. Further, the direction in which the groove extends is not limited to a straight line, and for example, it may be formed in a dogleg shape, an L shape, a corrugated shape, or the like that refracts the drawing direction.

In the above description, the U-shaped groove is described as an example extending in the P direction or the Q direction. However, if the shape can be pulled out in the horizontal direction with respect to the mounting male screw, the drawing direction is 2 It is not limited to the direction. Moreover, the installation direction of the U-shaped groove | channel in each attaching part can also be changed suitably as needed, and can be implemented.
For example, in the above embodiment, if the opening direction of the U-shaped groove 6a is the P direction, the hanger spacer 6 can be pulled out in the Q direction, that is, in the direction of the operator behind the ceiling.
