Description

[Detailed description of the invention] [Industrial application field] This invention reliably supports a relatively long gate using a simple foundation, and prevents obstacles such as rails from being placed on the ground where the gate opens and closes. This invention relates to a sliding gate that can be installed without forming anything.

[Conventional technology]

Most of the gates installed in places with relatively wide frontage, such as factories and schools, are either sliding type gates as shown in Utility Model Application No. 115244/1983, or sliding type gates as shown in Figure 1. has been done.

The sliding gate shown in Utility Model Application No. 51-115244 supports the gate between a fixed gate post and an active gate post, and also supports the gate on the floor surface by fixed wheels and flexible wheels provided at the bottom of the gate. and roll it.

In addition, the sliding gate shown in FIG. 1 has a support 21 erected on a foundation 20 set on the ground, and a gate main body 23 is inserted into the space 22 of the support 21 in a penetrating state so as to be movable in the horizontal direction. Upper and lower, left and right guide rollers 24 are provided and protrude into the space of the support body 21.
This supports the main body of the gate.

[Problem that the invention attempts to solve]

The direction-changeable sliding gate of Utility Model Application Publication No. 51-115244 has fixed wheels and flexible wheels that touch the floor surface (ground) to support the load of the gate when opening and closing the gate. This reduces the burden on the gateposts to some extent, but in reality, fixed gateposts and working gateposts are used with a distance between them, and one of the two wheels and the working gatepost are used to move the gate. is supported.

In other words, when the gate is closed, the fixed wheels are held in a floating state by the working gate post, and when the gate is opened, the fixed wheels are grounded due to a change in balance, and the free wheels are lifted up. More than half of the weight is always borne by this working gatepost, and since the load of the gate is applied to the working gatepost, at least the foundation of this working gatepost must be strong.

In addition, the gate of this invention has a structure that rotates at a predetermined angle around the operating gate post,
The working gatepost must be erected on a particularly strong foundation.

On the other hand, in conventional sliding gates, the gate body 23
is supported by the upper, lower, left and right guide rollers 24, so when the gate main body 23 moves and protrudes relative to the support body 21, a large moment will act on it.

Therefore, the foundation 2 supporting the support 21
0 must be strengthened, and by doing so, the foundation 20
The construction cost is high, and the gate body 23 has to be strong enough to prevent it from bending under its own weight, which increases the weight of the gate body 23. In addition, the gate body 23 has to be strong enough to avoid bending due to its own weight. There are various drawbacks such as the requirement for dimensional accuracy of the gate body 23 in order to position the gate body 23, and these are particularly noticeable in the case of a gate body having a long overall length.

[Means for solving problems]

In view of the current situation, this idea not only simplifies the foundation, but also makes the gate body lightweight.
Moreover, this is a completed sliding gate that does not require high dimensional accuracy of the gate body.

In other words, the sliding gate of this invention consists of a single support body constructed by connecting the upper parts of four pillars erected on a foundation with beams, and a single support body constructed by connecting each pair of pillars standing upright on the foundation. the support body includes at least a pair of guide rollers that can rotate while abutting and holding both sides of the upper end of the gate body; The gate main body has casters that roll on the ground at the bottom of both longitudinal ends, and a rail with a chevron-shaped cross section in the longitudinal direction of the lower surface, and a rail with a chevron-shaped cross section at the top thereof. The present invention is characterized in that it is mounted facing downward, and that a pair of support rollers are provided on the foundation, which can rotate in contact with the inclined surfaces on both sides of the rail having a chevron-shaped cross section.

[Effect]

In the sliding gate of this invention, one of the supports 1 constituting the sliding gate is as shown in the figure.
A base plate 5 is fixed on the foundation 2 with anchor bolts 3, and the upper parts between four pillars 5 erected on the base plate 4 are connected with beams 6a and 6b to form a unit.

On the other hand, the gate main body 10 is passed through in an upright state between each pair of opposing columns of the columns 5, that is, between the columns 5, 5 connected by beams 6b, 6b, and the upper part thereof is connected to the support 1. It is abutted and supported by guide rollers 7, 7, 7, 7 provided on the constituent beams 6a, 6a.

Further, in the lower part of the gate main body 10, both side inclined surfaces of the rails 11 provided on the lower surface of the gate main body 10 are supported by support rollers 9 provided on the base plate 4, and the gate main body
The weight of the gate body 10 is supported by the two casters 13 provided at the bottom of both ends of the gate body 10 in contact with the ground.

Therefore, since the upper part of the gate main body 10 is held between the plurality of guide rollers 7, the gate main body 10 is prevented from tilting sideways (in the left-right direction), and at the same time, the directionality in opening and closing is maintained. In addition, an auxiliary roller 14 provided on one beam 6a restricts unnecessary upward movement of the gate main body 10, and supports rollers 9,
To prevent the rail 11 from coming off from between 9 and 9.

Further, since the weight of the gate main body 10 is received by the support rollers 9, 9 and the casters 13, 13 provided at both ends of the lower surface of the gate main body 10, the load of the gate main body 10 is borne by these support rollers 9, 9, 9 and the caster 13, a large moment does not act on the foundation 2.

〔Example〕

Hereinafter, embodiments of the sliding gate of this invention will be described in detail based on the attached drawings.

The sliding gate of this invention basically consists of a support 1 and a gate main body 10 supported by the support 1.

The support 1 has a rectangular planar shape and is erected at the four corners of a substrate 4 that is fixed to the upper surface of a foundation 2 whose lower part is buried in the ground via anchor bolts 3.
Consisting of a book support 5 and four beams 6a, 6b that connect adjacent support posts 5 at the upper part, the long beam 6a has two horizontally rotatable pairs on the opposite lower surface. Guide rollers 7 are provided facing each other.

Further, a support piece 8 made of a steel material having a chevron-shaped cross section is fixed to the center of the board 4 with both edges thereof in contact with the board 4, in other words, with the top thereof positioned upward. On the slopes on both sides,
One support roller 9 that can rotate in a direction parallel to this inclined surface is provided.

On the other hand, the gate main body 10 has a thickness slightly smaller than the thickness between the circumferential surfaces of the opposing guide rollers 7, 7 provided on the pair of beams 6a, 6a of the support body 1,
Further, on the lower surface, a long rail 11 having a chevron-shaped cross section is provided integrally with the top thereof facing down, and the roller surface of the support roller 9, which is provided on each side of the support piece 8, comes into contact with the long rail 11. At the same time, casters 13 are provided at the lower portions of both ends of the gate main body 10 via caster mounting pieces 12, respectively.

Also, one beam 6 provided above the support body 1
An auxiliary roller 14 is provided inside a at a position slightly apart from the top surface of the gate main body 10.

In such a configuration, the gate main body 10
The guide rollers 7, 7 are installed on the beams 6a, 6a of the support body 1 in an upright state, passing through each pair of opposing columns, that is, between the columns 5, 5 connected by the beams 6b, 6b. , 7, 7, and the lower part thereof is supported by the rails 11 provided on the lower surface of the gate main body 10.
The inclined surfaces on both sides of the gate body 10 are supported by support rollers 9 provided on the base plate 4, and two casters 13 provided at the bottom of both ends of the gate body 10 contact the ground to support the gate body 10. It is.

In this state, the auxiliary roller 14 is disposed on the upper surface of the gate main body 10 with a slight distance from it to prevent the rail 11 from separating from the support roller 9 during use.

In addition, in the drawing, the support roller 9 is
Although it is mounted on the upright board 4, it is not necessarily limited to this.Four pillars 5 are set up on the foundation 2, a board is attached to the inside of each pillar 5, and a support roller 9 is attached to this. If the outer surface of the pillar 5 constituting the support 1 is covered with a plate, the appearance of the sliding gate will be further improved.

[Effect of idea]

The sliding gate of this invention consists of a single support body constructed by connecting the upper parts of four pillars erected on a foundation with beams, and a structure that penetrates between the opposing pillars of the support body in an upright state. It is like a gate body that can be moved in the length direction, and the weight of the gate body is supported by support rollers installed on the foundation and casters installed on the left and right lower ends of the gate body, so there is a large amount of weight on the foundation. Moment does not act.

Therefore, compared to the installation of conventional sliding gates, there is no need for extensive foundation work, the foundation itself can be made smaller, and the support that supports the gate body does not require as much strength. , it is possible to simplify the installation of sliding gates and provide them at low cost.

Furthermore, since approximately half of the weight of the gate body is supported by the support rollers, the gate can be opened and closed very smoothly.

In addition, since the upper part of the gate body is held between multiple guide rollers, it is prevented from tilting in the left and right direction, so there is no risk of the gate body falling over, and the cooperation with the support rolls prevents the gate body from tilting in the left and right directions. Therefore, the directionality in the opening/closing direction can be maintained even more reliably.

In addition, an auxiliary roller is provided to prevent the gate body from moving upwards unnecessarily.
This has many practical advantages, such as being able to open and close stably without fear of the gate body coming off the rail.

Furthermore, by substantially consolidating the support function and opening/closing function of the gate body into the single support described above, it becomes an obstacle for forming the gate on the passage, regardless of the length of the gate body. It is also excellent in that there is no need to form anything like this.
