Description

  The present invention relates to a double sliding door gate that opens and closes freely.

  The double sliding door type gate has been conventionally used, and in this type of gate, the sliding doors are arranged side by side in the thickness direction of the panel. The top sliding door on the door-end side has a truck attached to the door-end side and the non-door-end side, respectively, and a pair of wheels provided on each carriage is guided by a pair of guide rails installed on the ground to gate the door. It is possible to run independently in the opening and closing direction. On the other hand, the sliding door adjacent to this is cantilevered via a slidable connection with the leading sliding door, and the carriage is provided only on the non-door end side. The sliding door adjacent to the adjacent sliding door on the opposite side is similarly configured. That is, a pair of wheels provided on the carriage are guided by the pair of guide rails and can travel in the opening / closing direction under the cantilever support by the adjacent sliding doors except for the leading door on the door side.

Therefore, when the front sliding door at the door end side is pulled, it moves in the closing direction while sliding with respect to the adjacent sliding door, and when it reaches the sliding limit, it moves further in the closing direction while pulling the adjacent sliding door. The adjacent sliding door draws the adjacent sliding door while moving in the closing direction by itself. In this way, the sliding doors are sequentially drawn, the overlapping sliding doors are expanded, the gate is extended, and the doorway is closed.
Conversely, when the sliding door at the front end of the door is pushed, it moves in the opening direction while sliding with respect to the adjacent sliding door, and when the own truck hits the adjacent sliding door, it further pushes the adjacent sliding door. Move in the opening direction. The adjacent sliding door is pushed and moves in the opening direction while pushing the adjacent sliding door. In this way, the sliding doors are sequentially pushed and overlapped, the gate is contracted, and the doorway is opened.

Since the conventional multiple sliding door gates are engaged and connected as described above, if the engagement, that is, the contact state is bad, a large rubbing noise is generated when the sliding door is moved, or the movement is It was getting heavier. For this reason, the installation site took a long time to fine-tune the contact between sliding doors and look for a compromise.
Thus, multiple sliding door gates are popular because they can be stored compactly so that they do not get in the way at the time of opening, and recently they are expected to be used as gates for large facilities such as distribution centers and water treatment plants. Has been.
When using as a gate of such a facility, increase the size by increasing the height of the gate in consideration of security, or increasing the number of sliding doors to close the wide entrance. However, if the specifications can be adapted to these, not only the weight of each sliding door increases, but also the number of sliding doors increases, so the weight of the entire gate increases.
Therefore, the conventional fine adjustment alone cannot cope with it, and there is a concern that a larger rubbing sound may be generated or the movement becomes heavy and cannot be opened and closed.

  The present invention has been made by paying attention to the above-mentioned conventional problems, and has a relatively simple configuration and the height of the gate than the conventional one, while taking advantage of the idea of expanding and contracting by the double sliding door type cantilever support. The purpose of the present invention is to provide a new and useful double sliding door type gate that can be smoothly opened and closed without generating a high rubbing sound even if the height is increased or the number of sliding doors is increased.

In the current design, as shown in FIG. 7, a guide roller 103 protrudes outward from the side surface of the panel 101, and a guide rail 105 is engaged and connected to the guide roller 103. The mating portion is loosely fitted so that the guide roller 103 and the guide rail 105 can smoothly slide relative to each other. In addition, the engaging portion is separated from the center line L of the vertical load of the panel 101 (= the center line in the thickness direction of the panel 101).
Therefore, when the panel 101 receives a force in the tilting direction, the guide roller 103 hits the inner corner of the guide rail 105 at the lower engagement portion, and this is indicated by an arrow F as a fulcrum (portion surrounded by a dotted line). A falling moment is generated. This falling moment is further increased if the sliding door is raised or the number of sliding doors is increased.
This is the main cause of a loud rubbing noise and a heavy movement when moving the sliding door.

The present inventor has paid attention to the above cause and succeeded in proposing a gate having a structure in which a large falling moment is hardly generated as a result of trial and error.
According to a first aspect of the present invention, there is provided a double sliding door gate in which sliding doors arranged side by side in the thickness direction are engaged and connected to each other in the opening and closing direction. The guide roller is attached to the sliding door at a position below or near the center of gravity of the panel in a posture in which the axial direction is the horizontal direction, and from the other sliding door, the guide rail of the mating partner is attached to the one sliding door. The double sliding door gate is characterized in that it extends in the direction and the guide rail supports the vertical load of the panel via the guide roller.

  According to a second aspect of the present invention, in the double sliding door gate according to the first aspect, the guide roller has a V-shaped groove, and a vertical load is applied to the groove bottom surface of the V-shaped groove. It is a characteristic double sliding door gate.

  According to a third aspect of the present invention, in the double sliding door type gate described in the first or second aspect, as an upper engagement connecting mechanism, a guide roller is attached to one of the sliding doors in a posture in which the axial direction is a vertical direction. The other sliding door is provided with a pair of guide rails to be engaged, and a pair of the guide rails are provided and the guide rollers are sandwiched in a direction perpendicular to the opening / closing direction, or a pair of the guide rolls are provided. A double sliding door gate characterized in that the guide rail is sandwiched in a direction perpendicular to the opening and closing direction.

  According to a fourth aspect of the present invention, in the double sliding door gate according to the third aspect, in the upper engagement connecting mechanism, the guide roller is attached to the inner side or the upper side of the panel of the other sliding door. This is a double sliding door gate.

  According to the double sliding door type gate of the present invention, even if the height of the gate is increased or the number of sliding doors is increased, generation of loud rubbing noise is suppressed and smooth opening and closing is ensured.

On the other hand, with respect to the remaining sliding doors 5B, 5C,..., The carriage 17 is provided only on the non-door end side, and can run under cantilever support by the adjacent sliding doors.
Also in the present invention, the cantilever support is realized by an engaging connection in which the adjacent sliding doors 5 and 5 are slidable with each other. In this gate door 1, as shown in FIG. The two are engaged and connected at the lower side and the upper side.

The enlarged view is an engagement connecting portion between the sliding door 5A and the sliding door 5B, and the mechanism will be described by taking this portion.
First, the lower engagement connecting mechanism will be described with reference to the enlarged view (2) of FIG. 2 and the schematic view of FIG.
Engaging partners are the guide roller 21 and the guide rail 37.

The guide roller 21 is attached to the sliding door 5B.
The roll surface of the guide roller 21 is a perfect circle having the same diameter in the cross section perpendicular to the axial direction, and an annular groove 23 is formed in the middle of the axial direction. The annular groove 23 is substantially V-shaped, and two groove inner surfaces 27, 27 surround a groove bottom surface 25 having a certain width dimension in a tapered shape. A cylindrical support shaft 29 is fixed in a penetrating manner in the axial direction of the guide roller 21.

The lower rail 15 of the sliding door 5B has a lower surface that is open on the non-door end side, and the shaft support holes 31, 31 at the same height on the side plate portions on both sides in the thickness direction facing each other across the opening. Are formed respectively.
The guide roller 21 enters from the opening. The support shafts 29 and 29 projecting on both sides communicate with the shaft support holes 31 and 31 in a straight line. Bolts 33 are inserted therein, and nuts 35 are screwed to be fastened and fixed.

With the above-described attachment, the lower portion of the guide roller 21 protrudes downward from the lower rail 15, and the rolling direction is parallel to the rolling direction of the wheels 19 of the carriage 17.
Further, the axial center direction of the guide roller 21 is a horizontal direction, and the center line L (= center line in the thickness direction of the panel 7) of the vertical load of the panel 7 of the sliding door 5B is the groove bottom surface 25 of the guide roller 21. It overlaps with the center line, and the vertical load of the panel 7 is applied to the groove bottom surface 25.

The guide rail 37 is extended to the sliding door 5A.
The guide rail 37 is formed by bending an elongated rectangular plate material in two places parallel to the long edge, and the cross-sectional shape in the short direction is the same. It is bent vertically toward the same side, and two vertical portions are raised with the horizontal portion interposed therebetween. Of these two vertical portions, the higher one is a mounting portion 39. The attachment portion 39 is in contact with the side surface of the lower rail 15 and is fastened and fixed to the lower rail 15 by bolts 40 and nuts 41. The lower one is a narrow rail section 43. An upper surface 45 (plate thickness surface) of the rail portion 43 is a flat surface.

The reinforcing member 42 is fastened and fixed to the lower surface of the lower rail 15 by bolts 40 and nuts 41. The reinforcing member 42 supports the horizontal portion of the guide rail 37, and the guide rail 37 is stably attached to the sliding door 5A.
With this attachment, the guide track of the guide rail 37 is parallel to the guide track of the rail 3.

The guide rail 37 on the side of the sliding door 5A wraps around from the lower side with respect to the panel 7 of the sliding door 5B using a lower clearance space. The rail portion 43 rises in the vertical direction, and its upper surface 45 is a horizontal surface, and is in full contact with the groove bottom surface 25 of the guide roller 21. The center line L of the vertical load of the panel 7 also overlaps with the center line of the upper surface 45. In addition, the groove inner side surfaces 27, 27 sandwich the rail portion 43 from both sides.
By such engagement connection, the guide roller 21 rolls on the guide rail 37 as the wheel 17 rolls. The rail portion 43 stably supports the vertical load of the panel 7 under the center of gravity line (L) through line contact on the upper surface 45, and the engagement fulcrum (portion surrounded by the dotted line) is the center of gravity line (L ) Because it is below, even if it receives force in the direction of falling, the falling moment will not increase.

In addition, what is shown in FIG. 4 is mentioned as a modification of the guide rail 37. FIG.
In FIG. 4A, the guide rail mounting portion 47 is horizontal and is attached to the lower rail 15 from below.
In FIG. 4B, the guide rail 49 is integrated with the shape member 51 of the lower rail.
In FIG. 4C, the horizontal portion of the guide rail 53 is long, and a U-shaped guide rail 55 is attached to the inside thereof to form a two-layer structure. The horizontal inner bottom surface 57 of the guide rail 55 is in contact with the roll surface of the guide roller 21, and the opposed inner side surfaces 59, 59 are disposed so as to sandwich the guide roller 21 from both sides. In this configuration, the inner side surfaces 59 and 59 have a function of preventing the lateral displacement of the guide roller 21 and are greatly increased by a large area.
In any case, similar to the guide rail 37, the vertical load of the panel 7 is supported under the center of gravity (L), and the same effect can be expected.

Next, the upper engagement connecting mechanism will be described with reference to the enlarged view (1) of FIG. 2 and the schematic view of FIG.
As the adjacent sliding doors, description will be made using the sliding door 5A and the sliding door 5B as representative examples.
Engaging partners are the guide roller 61 and the guide rail 75.

The guide roller 61 is attached to the sliding door 5B.
The roll surface of the guide roller 61 is a perfect circle having a cross section perpendicular to the axial direction and having the same diameter, and an insertion hole is provided in the axial direction.
A bracket 63 is used for attachment. The bracket 63 is formed by bending the plate surface to have an L-shaped cross section, and bolt through holes are formed in the pieces on both sides. The bracket 63 is arranged so as to have an inverted L shape. The vertical piece is abutted against the side surface of the upper rail 9 of the sliding door 5B and is fastened with bolts and nuts 65 from the outside, and the horizontal piece moves up and down the plate surface. Projecting outwards toward.

The bolt 67 has a function as a support shaft of the guide roller 61, and the guide roller 61 and a washer 69 are inserted therethrough. Then, it is inserted into the bolt through hole of the horizontal piece of the bracket 63 from above, and is fastened from above and below by a pair of nuts 71 and 73 and fixed to the bracket 63. The axis of the bolt 67 faces the vertical direction.
There is a gap between the upper nut 71 and the head of the bolt 67, and even if the washer 69 is inserted, the guide roller 61 can rotate and the bolt 67 serves as a support shaft. The core is in the vertical direction. The guide roller 61 protrudes upward from the bracket 63, and the roll surface faces in the lateral direction.
With the above-described attachment, the rolling direction of the guide roller 61 is perpendicular to the rolling direction of the wheels 19 of the carriage 17.

The rail member 75 is attached to the sliding door 5A.
The rail member 75 is formed by bending an elongated rectangular plate material in two places parallel to the long edge, and has the same cross-sectional shape in the short direction. Two vertical parts extend in the opposite direction across the horizontal part. One of the two vertical portions is an attachment portion 77, which is in surface pressure contact with the side surface of the upper rail 9 of the sliding door 5A by a fixing bracket 79, and the rail member 75 is stably attached to the sliding door 5A. Yes.

The other vertical portion is suspended and serves as a guide portion 81. A guide roller 61 is inserted into and engaged with a gap between the guide portion 81 and the outer surface of the upper rail 9 of the sliding door 5A facing the guide portion 81. That is, a guide rail is constituted by a combination of the upper rail 9 and the rail member 75, and the guide track is parallel to the guide track of the rail 3.
The upper engagement connecting mechanism is configured in this way, and is specialized in regulating lateral displacement.

Since the lower engagement coupling mechanism supports the vertical load of the panel 7, as described above, the upper engagement coupling mechanism can specialize in restricting the lateral displacement, By causing the engaging and coupling mechanisms to have specialized functions, it is possible to more effectively prevent the occurrence of a large falling moment.
Therefore, in order to ensure a smooth movement, even if the guide roller 21 and the guide rail 37 and the guide roller 61 and the guide rail 75 are engaged together in a loosely fitted state, it is difficult to fall down.
Since the gate 1 is composed of six sliding doors 5A, 5B, 5C, 5D, 5E, and 5F, the front sliding door 5A has a load of five sliding doors 5B, 5C, 5D, 5E, and 5F. However, as described above, the five sliding doors 5B, 5C, 5D, 5E, and 5F are each independently independent even under cantilever support, and can accommodate a large design of the gate 1.

In addition, what is shown in FIG. 6 is mentioned as an example of a change of the guide roller 61 and the guide rail 75. FIG.
In FIG. 6A, the guide rail 83 is provided as a concave portion on the upper side of the upper rail 9, and the guide roller 61 enters there.
In FIG. 6B, the guide rail 85 is provided as a concave portion on the side of the upper rail 9, and the guide roller 61 enters the guide rail 85.
If comprised in this way, since it becomes unnecessary to ensure the space for arrange | positioning a guide roller between sliding doors, it becomes possible to make the panel 7 more closely_contact | adhere.

It is also possible to configure the pair of guide rollers to sandwich the guide rail.
For example, in FIG. 6C, a guide rail 87 is attached to the upper side of the upper rail 9 in a flat bar shape, and the guide rail 87 is sandwiched between a pair of guide rollers 89 and 89.
In FIG. 6D, the upper rail 9 itself is used as a guide rail, and the upper rail 9 is sandwiched between a pair of guide rollers 91 and 91.
These modified examples have a structure specialized for preventing lateral displacement, and the same effect can be expected.

As mentioned above, although the embodiment of the present invention has been described in detail, the specific configuration is not limited to this embodiment, and other than the above description, the design can be changed without departing from the gist of the present invention. It is also included in the invention.
For example, the upper rail 9, the vertical rails 11 and 13, and the lower rail 15 are not limited to an aluminum extruded material, and may be formed of a steel or stainless steel tube-forming material.
