Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sliding gate that opens and closes in a horizontally extending manner.

Conventional technology A gate that opens and closes sideways from side to side is supported by passing through a gate-shaped post to prevent it from falling down. A sliding door bar m, which supports a gate by means of a sliding door bar, is related to the applicant's application and is widely used throughout the country (publication of Utility Model Publication No. 13148/1983).

This device prevents the gate from collapsing and controls the direction when opening and closing, using a gate-shaped support and a rail extending behind the gate to guide the hanging wheel. Therefore, not only can the gate be finished in a thin and sleek shape, but there is no need to install any special guide rails on the ground, so it can be installed in places such as factories where heavy vehicles often come in and out. In addition, it is suitable for opening and closing operations at all times without causing problems when opening and closing due to gravel, dirt, etc. getting caught on one side of the ground. It is something.

Problems to be Solved by the Invention However, since this gate is supported by the entire gate, the bottom wheel at the front end, and the hanging wheel at the rear upper end, the force required to open and close the gate is particularly light. When necessary, it is common practice to make the width of the groove provided in the suspension wheel sufficiently larger than the thickness of the rail so that the suspension wheel can be smoothly transferred at the upper edge of the rail. Therefore, when adopting such a structure, during strong winds, the wind pressure may cause the entire gate to shift or shift in the direction perpendicular to the direction of opening and closing. As a result of abnormally high contact pressure between the upper and lower frames and the guide roller built into the portal column,
This creates a problem in that opening and closing the gate may become extremely difficult.

Therefore, in view of the problems of the prior art, an object of the present invention is to increase the wind pressure by devising the shapes of the bottom of the hanging wheel and the upper edge of the rail, instead of increasing the width of the groove of the hanging wheel. To provide a sliding door that can be easily opened and closed at all times, since the risk of the entire opening being misaligned can be minimized even if the gate is opened.

Means for Solving the Problems The structure of the present invention to achieve the above object includes a portal column with a kite roller, an imago at the front end, and
A bar m that has a hanging wheel at the rear end and opens and closes horizontally.
and a rail extending behind the gate, the radius of curvature of the upper edge of the rail is smaller than that of the groove of the hanging wheel, and the contact position of the hanging wheel and the rail is adjusted throughout the entire stroke of the gate. The gist is that a means for adjusting the mounting position of the rail is provided so as to match the deepest part of the groove of the hanging wheel.

In the case of the above configuration, the radius of curvature 1 of the upper edge of the rail is smaller than the radius of curvature of the groove of the hanging wheel.
°The upper edge of the rail can penetrate to the deepest part of the groove of the hanging wheel that is transferred over it, and the load on the hanging wheel is approximately 1/2 of the total weight of the gate, so there is strong wind pressure. Even in the presence of
In general, a means for adjusting the mounting position of the rail is provided to ensure the above-mentioned relative relationship throughout the entire stroke of the gate, which eliminates the inconvenience of partially opening/closing the bar or making it heavy. It acts in such a way that there is no risk of this occurring.

Example Examples will be described below with reference to the drawings.

Sliding gates are gates that open and close sideways @10 and gates 10
The main members are a portal support 20 and a rail 31 for guiding the vehicle (Fig. 1).

The gate 10 has a rectangular frame made up of front and rear vertical frames 11, 12, an upper frame 13, and a lower frame 14, and has a large number of lattice bars 15, 15 inside. In addition to standing J2, a pass-through door 16 is assembled via hinges 16a, 16a. A bottom wheel 17 is provided at the front end of the gate 10, while a hanging wheel 18 is provided at the rear end from the center of the vertical frame 12 above the ball.

The bottom wheel 17 is a large door wheel fixed to the lower surface of the front end of the lower frame 14. The bottom wheel 17 can be a standard one made of metal or with rubber tires. It is possible to run on the ground surface GL, which has undergone finishing work. On the other hand, the hanging wheel 18 is a grooved wheel that rolls on a rail 31 (Fig. 3), and the wheel 18a is pivoted to a bracket 18b, and is attached to the back side of the vertical frame 12 via this bracket 18b. It is screwed on. Further, the upper half of the hanging wheel 18 is covered with a cover 18c to protect it from rain.

The gate-shaped support 20 has two support supports 21 and 21 erected so that it can support the gate 10 from both sides (Fig. 2). In order to sandwich and support the frame 13 and the lower frame 14 on both the front and back sides,
A total of four guide rollers 22, 22, 2 g each on the upper and lower sides, are rotatably mounted. Kiteroller 22.22・
It is preferable that the periphery of the contact surface (A) with the gate [O] be formed into a circular cross section.In addition, the base of the support column 21.210 is formed through the foundation concrete 21a. The top part is connected in a gate shape with a connecting plate 23.The portal support 20 is erected near the rear end of the bar tTi 10 when closed. (Fig. 1), the gate] O passes through this gate-shaped support 20, and is held by guide rollers 22, 22, etc. throughout the entire opening and closing process. .

The rail 31 is an angle member that is supported by a plurality of supports 32, 32, and extends behind the back side of the gate ``O'' (Figs. 1 and 3). The fixation of is to the long holes 31a, 31a provided in the rail 31,
Insert the ports 32b and 32b set up on the top of the support column 32, and tighten the nuts 32C132C, spring washers 32d,
32d and washers 32e, 32e, by screwing the rail 31 in a direction perpendicular to its longitudinal direction so as to be adjustable (FIG. 4). Here, the bolts 32b, 32b are
The base of the column 32 is erected via a base plate 32a fixed to the tip of the column 2, and the base of the column 32 is buried in the soil similarly to the portal column 20.

At the rear end of the rail 31, a release stopper 33 is provided.
Closing stoppers 34 are respectively attached to the front ends (FIG. 1), and the former stopper 34 is attached to the vertical frame 12 of the bar m10.
The latter is fixed so as to protrude from the rail 31 toward the gate @10 so that it can come into contact with it, while the latter is provided so as to protrude above the rail 31 so as to act as a stopper for the hanging wheel 18.

A kite post 35 having substantially the same configuration as the gate-shaped support 20 is installed at the reach 1 of the front end of the gate n10 when closed, and when the gate 10 is closed, at least the vertical frame 1
A part of the guide post 35 is designed to enter the guide post 35.

The relative relationship between the hanging wheel 18 and the rail 31 can be explained as follows (FIG. 5). First, use it for the hanging wheel 18.
The turret 18a has a radius of curvature R1 symmetrical about its center 18e.
It is a grooved groove formed by forming a groove 18d having an arcuate cross section on the periphery. On the other hand, the rail 31 is made of a well-known angle material, and the edge of the - side is left as is.
It is used as the upper edge 31b of the rail 31 on which the hanging wheel 18 rolls, and its radius of curvature is R31. Therefore, between the radii of curvature R18 and R31, R
18>R31 is established.

When installing a sliding gate with such a configuration, the rail 31
For each support column 32 that supports, elongated holes 31a, 31a,
The relative positional relationship between the rail 31 and the hanging wheel 18 of the gate R10 is adjusted using means for adjusting the mounting position of the rail 31, which is comprised of the bolts 32d, 32d and the nut 32C132G. In other words, the entire stroke of the gate] O (after kneading, the upper end of the rail 31 is 31b, and the upper end of the rail 31 is the deepest part of the groove 18d formed in the wheel 18a of the hanging wheel 18, and the rail 31
After setting the mounting position of the rail 31 so that the rails are aligned in a straight line, the tightening of the nuts 32C132c is completed.

In this state, the groove 18d of the hanging wheel 18 is
Since it is formed in an arc shape symmetrical with respect to the center 18e, the position of the deepest part of the groove 18d coincides with the position of the center 18e, so that the suspension wheel 18 and the rail 3
1 means that the former groove 1 is always used throughout the entire process of the gate 10.
The upper edge 31 of the latter on the line corresponding to the deepest part of 88
b can realize a relationship in which point contact is made.

Furthermore, the hanging wheel 18 is provided with approximately 1// of the total weight of the gate 10.
' Since F[ of 2 is acting, the above rail 31
The relationship in which the upper edge 31b contacts the deepest part of the groove 18d of the hanging wheel 18 is the most stable state, and therefore, this relationship can be maintained for a long period of time even after the sliding gate is placed in the 3Q position. It's something. As long as the above-mentioned relative relationship is maintained between the hanging wheel 18 and the rail 31, the traverse path of the gate 10 during opening and closing can always be maintained at a constant position. Therefore, the guide rollers 22, 22... incorporated in the portal support 20...
Since there is no fear that the relative positional relationship between the gate m10 and the gate m10 will change, the contact pressure against the guide rollers 22, 22, etc. will increase, and the opening and closing of the gate m10 may be unexpectedly heavy. There is a market for products that can effectively eliminate the risk of causing problems such as bending.

The mounting position of the hanging wheel 18 to the gate f11Q is as follows:
The contact position of the rail 31 and the height of the bolt Jn10 (
The position can be selected to be 50 to 100% from the lower end of the gate 10 with respect to the length dimension of the vertical frame 12. However, here, 50% refers to the center position of the vertical frame 12,
100?6 shall refer to the upper DjT position.

Increasing the mounting position of the hanging wheel 18 when the height of the gate 10 is large is a strong 71 construction [when wind pressure acts on the gate 10 below, the gate 10 is suspended by the hanging wheel 18]. As a result of the increased shaking at the lower end of the rear, the guide roller 22.2 has sunk into the portal support 20.
2...The contact pressure against the object below becomes abnormally high,
Therefore, this is a problem that may impede the ease with which the gate 10 can be opened and closed. Therefore, the height dimension of gate @10 is 1
000a++ or less, the mounting position of the hanging wheel 18 is 10
Although it may be set to 0%, it has been found that it is better to set it to approximately 70% or less when the distance is from 150C to 2000 mm, and to approximately 60% or less when the distance exceeds 2000 m.

However, if the hanging wheel 18 is installed at a position lower than the hand center position of the gate 10, there is a risk that the stability of the gate fW: 10 will be essentially lost. It goes without saying that % or more is better. In addition, since the pressure receiving area for wind pressure changes depending on not only the height dimension of the gate 10 but also its total length, when the total length of the gate and guard 10 is long, it is better to install the hanging wheel 18 at a lower position. .

Further, as means for adjusting the mounting position of the rail 31 with respect to the support column 32, a bolt 32b installed upright at the top of the support column 32;
32b and the elongated holes 31a, 31a formed in the rail 31, the base plate 32a fixed to the tip of the support 32 is formed sufficiently large so that it protrudes from the support 32. Two parallel long holes are provided in the base plate 32a, and bolt holes corresponding to these long holes are provided in the rail 31, and bolts are inserted through these long holes and the bolt holes to screw them. In this case, the elongated hole is formed in the column 32 of the base plate 3'2a.
It shall be provided on the protruding part from the
As before, it goes without saying that the direction is perpendicular to the longitudinal direction of the rail 31. Since it can be fastened using standard bolts and nuts, on-site installation and adjustment work is easier.

Roughly speaking, both sides of the upper half of the rail 31 can be rounded to a radius of curvature R31 (FIG. 6). Since the center 18e of the wheel 18a of the hanging wheel 18 and the center of the rail 31 in the thickness direction can be set apart from -i, the hanging wheel 1
8 and the rail 31 can be kept more stable relative to each other.

In addition, when driving along the gate R10, existing concrete 1, 1, IF' or a building, the bracket 36 is attached to the concrete 1mF etc. via the embedded bolt 36a.
It is also possible to fix the rail 31 to the bracket 36 and screw the rail 31 onto the bracket 36 (FIG. 7). Since the pillars 32, 32, etc. are not required, manufacturing costs can be reduced. In this case as well, the rail 31 is provided with elongated holes 31a, 31a@ in the front j as a means for adjusting the mounting position of the rail 31 with respect to the bracket 36.

As described in detail, according to the present invention, a gate that opens and closes horizontally is supported by a bottom wheel at the front end and a hanging wheel at the rear end, and is also supported by passing through a gate-shaped support. On the other hand, a rail is extended to the rear to guide the hanging wheel, and the radius of curvature of the upper edge of the rail is smaller than half the curvature of the groove formed in the hanging wheel, and over the entire stroke of the gate, Once the relative positional relationship between the hanging wheel and the rail is set, by providing a means for adjusting the mounting position of the rail so that the connecting position of the hanging wheel and the rail coincides with the deepest part of the groove of the hanging wheel, Since the load of approximately 1/2 of the total weight of the gate is applied to the hanging wheel, there is extremely little risk that the relative relationship will shift due to wind pressure even in strong winds, thus ensuring easy opening and closing operations at all times. It has the disturbing effect of being able to do something.
