Description

  The present invention relates to a blocking bar and a blocking device that restrict the passage of vehicles at a toll gate on a toll road.

In recent years, automatic toll collection systems (hereinafter referred to as “ETC system”) are increasingly used for toll road tolls, and vehicles can pass without paying tolls to this toll. Therefore, the traffic jam of the vehicle at the toll gate is alleviated. This system communicates with the equipment installed in the vehicle that entered the toll gate by the toll gate antenna, and when allowing the vehicle to pass, the blocking bar, which is always horizontal, is rotated upward to become vertical. The passage is allowed. The main part of the blocking rod is usually made of a core material made of aluminum and foamed urethane (rigid urethane foam) wrapped around it, and is characterized by being a lightweight elastic material.
However, when the vehicle enters the toll gate at a high speed, the upward rotation of the blocking rod is not in time, and the vehicle may collide with the blocking rod. Since the material of the blocking bar is the above-described elastic material, the impact at the time of collision is moderated to some extent, but the blocking bar may be broken or the vehicle may be damaged.

In order to solve the above-mentioned problem, a blocking rod having a rubber tube formed by compressing and filling air has been proposed (for example, see Patent Document 1).
The blocking rod of Patent Document 1 includes a flexible cylindrical body made of a rubber-like elastic body and a rubber tube in which air is compressed and filled inside the cylindrical body.
For this reason, even if the vehicle collides with the blocking rod and the blocking rod is bent, the blocking rod is surely restored by itself, so that the blocking rod breakage accident can be reduced.

Hereinafter, the present invention will be described in detail with reference to FIGS. In addition, this invention is not limited to these figures, It can change into a various form.
The blocking bar of the present invention includes a long bag body compressed and filled with gas, and a support member that supports the long bag body, and the long bag body overlaps at least two bag bodies. It is characterized by being formed in a structure of two or more layers.

[1] Blocking bar The “blocking bar” is attached to a blocking machine installed at a toll booth on the toll road, and when allowing the vehicle to pass, it is in a vertical state to allow the vehicle to pass and to reject the vehicle When it does, it becomes a horizontal state and blocks | prevents passage and is provided with the elongate bag body formed by compressing and filling gas, and a support member.
For example, the blocking bar 10 shown in FIG. 1 includes a long bag body 11 and a support member 13.

(1) Long bag body For example, the long bag body 11 shown in FIG. 1 comprises the main part of the blocking rod 10, and is formed by compressing and filling gas. Since the inside of the long bag body 11 is hollow, the material cost of the blocking bar 10 can be kept low. Further, the shape of the long bag body is not particularly limited as long as it is a long bag shape having a function of preventing passage of the vehicle, and may be a cylindrical shape, a rectangular tube shape, or a combination thereof in appearance. However, it is preferable that it is cylindrical shape as shown in FIG. This is because the cylindrical shape can uniformly apply the gas pressure to the entire side surface of the long bag body, and can easily maintain a stable shape.
The elongate bag body is formed in a structure of two or more layers by superposing at least two or more bag bodies. “Two or more layers” means at least two layers, including three layers, four layers or more.
As shown in FIGS. 3 and 4, the long bag body 11 includes an inner long bag body 11 c having airtightness retention and an inner side long bag body that covers the inner long bag body 11 c and has shape retainability. 11b and the outer side long bag body 11a which covers the middle side long bag body 11b and has a low friction property, are formed in the three-layer structure.

The inner elongate bag body 11c constitutes the innermost part of the elongate bag body 11, and the inner side is in direct contact with the compressed and filled gas. The inner elongate bag body 11c has an airtight holding property so that the compressed and filled gas does not leak to the outside.
The material is not particularly limited as long as it has an airtightness retaining property, but is preferably a polyurethane sheet. A polyurethane sheet can be suitably used because it is excellent in airtightness retention and also excellent in flexibility and strength.

  The inner elongate bag body is preferably provided with a gas inlet for injecting gas. According to the gas injection port, it becomes easy to compress and fill the inner long bag body with gas. For example, the gas injection port 11 k shown in FIG. 1 is provided so as to protrude from the support member 13. The position of the gas inlet is not particularly limited, but is preferably provided on the side of the long bag body 11 closest to the support body 13 as shown in FIG. By doing so, contact with a passing vehicle can be prevented. The member of the gas inlet is not particularly limited as long as gas can be injected, but as shown in FIG. 1, a tire valve such as an automobile can be used normally.

The “gas” is not particularly limited as long as it can be compressed and filled into a long bag body, but it is preferable that it is excellent in safety and has a small volume change due to temperature. For example, nitrogen gas or air can be preferably used.
The gas pressure inside the long bag body only needs to play a role as a blocking bar. If the pressure is too high, there is a risk of breakage. If the pressure is too low, the shape of the blocking bar must be maintained. Is difficult. It is preferably 1.20 to 1.90 kg / cm 2, and more preferably 1.75 to 1.90 kg / cm 2.

The middle elongate bag body 11b constitutes an intermediate portion of the elongate bag body 11, covers the inner elongate bag body 11c, and is covered by the outer elongate bag body 11a. The middle elongate bag body 11b has shape retention so as to reliably retain the shape of the entire elongate bag body 11 and prevent deformation.
The material is not particularly limited as long as it has shape retention, but is preferably made of polyamide fiber, polyester fiber, polyurethane fiber, polyolefin fiber, or a mixed material thereof. More specifically, nylon (nylon 6, nylon 66), polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, polyurethane or a mixed fiber thereof can be exemplified.

The outer long bag body 11a constitutes the outermost part of the long bag body 11, and the outer side is in direct contact with the outside air. When the vehicle collides, the friction with the vehicle is reduced to prevent the outer long bag 11a from being damaged, and the vehicle has low friction so as to prevent the vehicle from being damaged.
The material is not particularly limited as long as it has low friction, but is preferably a polyurethane sheet. If it is a polyurethane sheet, since the surface is smooth and it is excellent in low friction property, it can be used conveniently.

  The long bag body preferably further includes a shock-absorbing cylinder that covers the middle long bag body and is covered by the outer long bag body. By providing this cylindrical body, even if the air pressure inside the long bag body decreases, the shape of the long bag body can be further stabilized, and the impact can be absorbed even if the vehicle collides. For this reason, for example, even if a mirror support member of a large vehicle collides with the long bag body, the long bag body can be prevented from being wrapped around the mirror support member.

  For example, as shown in FIG. 5 and FIG. 6, the long bag body 15 covers the middle long bag body 11 b and is covered with the outer long bag body 11 a in the long bag body 11. The cylindrical body 15d is further provided. The cylindrical body 15d is not particularly limited as long as it is a material that absorbs impact, but for example, a hard vinyl chloride material can be used. As shown in FIGS. 5 and 6, the hard vinyl chloride preferably has punching holes 15dh perforated over the entire cylinder 15d so as to have a mesh shape. By doing so, the elasticity can be increased and the shock absorption can be increased.

(2) Support Member The “support member” is a member that supports the long bag body. The support member supports the long bag body and is connected to the blocking device via a connecting member.
The support member includes an insertion part for detachably attaching the outer long bag body, a connection part connected to the insertion part, and an attachment part connected to the connection part and inserted into the blocking device. , Can be configured.
If it is this structure, although there is no limitation in particular, it can be set as the following 1st form-3rd form, for example.

(First form)
For example, as shown in FIG. 7, the support member according to the first embodiment is configured such that the support member 23 removably inserts the outer elongate bag body 21 and a connection connected to the insertion portion 23 c. It is comprised from the part 23b and the attaching part 23a which is connected to the connection part 23b and is attached to a blocking machine.
Here, the long bag body 21 has the same configuration as that of the long bag body 11 except that the gas injection port 21k is located at the center of the bottom surface.

It is preferable that the entire outer surface of the long bag body 21 abuts on the inner surface of the insertion portion 23c. In this case, even if an impact is applied to the long bag body, the impact force is dispersed throughout the insertion portion 23c. The impact on the support member is alleviated.
The material of the insertion portion 23c is not particularly limited, but is preferably a synthetic resin excellent in soft strength. In this way, the long bag body 10 can be inserted and fixed without damaging it. For example, vinyl chloride leather can be used.
In order to fix the elongate bag body 21 to the insertion portion 23c, the gas is injected into the elongate bag body 21 from the gas injection port 21k to some extent, or after being inserted into the insertion portion 23c, without being injected. The long bag body 21 can be compressed and filled with gas, and can be pressed and fixed by its internal pressure. Furthermore, the contact portion may be fixed by adhesion. Since the long bag body 21 can be detachably inserted into the insertion portion 23c, the long bag body 21 can be easily replaced even when one of the long bag body 21 or the support member 23 is damaged.

The attachment portion 23a is a member that attaches the support member 23 to the connecting member of the blocker, and can be a cylindrical shape, a rectangular tube shape, etc., as long as it can be attached to the connecting member.
The material of the mounting portion 23a is not particularly limited, and may be made of metal such as aluminum, hard synthetic resin, glass fiber, or wooden.
The attachment portion 23a shown in FIG. 7 has a cylindrical shape, and is connected to the insertion portion 23c through the connection portion 23b. The shape and the like of the connection portion 23b are not particularly limited. For example, as shown in FIG. 8, an outer surface connection material 23b2 that is in contact with the outer surface of the attachment portion 23a and an inner surface connection material that is in contact with the inner surface of the insertion portion 23c. 23b1 can be fixed by the fixing tool 24.
Note that the connecting portion is not necessarily required. For example, the inserting portion 23c and the attaching portion 23a may be directly connected by bonding, sewing, or the like.

(Second form)
As for the support member which concerns on a 2nd form, an insertion part and an attachment part are a straight cylinder shape, and the connection part is formed in the funnel shape which narrows gradually toward an attachment part from an insertion part. Although the bottomless cylindrical shape may be sufficient as the side facing the connection part of an attachment part, it is preferable that it is a bottomed cylindrical shape. If it is a bottomed cylindrical shape, while being excellent in intensity | strength, it can prevent that dust etc. penetrate | invade into the inside of a supporting member.
For example, as shown in FIG. 1, in the support member 13 according to the second embodiment, the insertion portion 13 c and the attachment portion 13 a have a right cylindrical shape, and the connection portion 13 b gradually increases from the insertion portion 13 c toward the attachment portion 13 a. It is formed in a funnel shape that narrows. If it is the support member 13, when a long bag body receives an impact, since an impact can be absorbed equally over the whole circumferential direction, damage to the whole blocking rod can be prevented effectively.
As shown in FIG. 2, the support member 13 is provided with a connecting member mounting hole 13ah in the mounting portion 13a and a gas inlet hole 13bh in the connecting portion 13b. The gas inlet 11k of the long bag body 11 protrudes from the gas inlet hole 13bh.
Moreover, as shown in FIG. 4, the attachment part of the support member 13 is formed in the bottomed cylindrical shape in the side facing a connection part.

The material of the support member is not particularly limited, and can be made of metal such as aluminum, hard synthetic resin, glass fiber, or wooden. Among these, a hard synthetic resin is preferable.
Furthermore, it is particularly preferable that the support member is integrally formed of a hard synthetic resin. By integrally forming with a hard synthetic resin, it is excellent in strength and can be easily manufactured by blow molding or the like.
The material of the hard synthetic resin is not particularly limited, and polypropylene, polyethylene, and the like can be suitably used.

As shown in FIGS. 1, 2, and 4, a cylindrical protective sheet 12 can be further provided between the support member 13 and the long bag body 11. The protective sheet 12 is preferably a synthetic resin excellent in soft strength, and plays a role of protecting the long bag body from the hard insertion portion 13c. In particular, when an impact is applied to the long bag body, the long bag body can be prevented from being bent at the distal end portion of the hard insertion portion 13c.

As a material of the protective sheet 12, for example, vinyl chloride leather can be used. The protective sheet 12 may be simply inserted into the insertion portion 13c and pressed and fixed by the internal pressure of the long bag body, but it is preferable to adhere to the inner surface of the insertion portion 13c to such an extent that it can be detached.
In order to fix the elongate bag body 11 to the insertion portion 13c via the protective sheet 12, the elongate bag body 11 may be inserted after injecting gas from the gas injection port 11k to some extent or without injection. It can be inserted into the portion 13c, and then the long bag body 11 can be compressed and filled with gas and pressed and fixed by its internal pressure. Furthermore, the contact portion between the protective sheet 12 and the long bag body 11 may be bonded and fixed.
In addition, since the fixing method to the supporting member 73 of the elongate bag body 11 is the same as that of a 1st form, the description is abbreviate | omitted.

(Third form)
In the support member according to the third aspect, the insertion portion and the attachment portion are formed in a straight cylinder shape, and the connection portion is formed in a funnel shape gradually narrowing from the insertion portion toward the attachment portion, and the longitudinal direction of the attachment portion Is eccentric with respect to the longitudinal center axis of the insertion portion. That is, the third embodiment is such that, in the second embodiment, the central axis in the longitudinal direction of the attachment portion is eccentric with respect to the central axis in the longitudinal direction of the insertion portion.
For example, as shown in FIGS. 9 and 10, in the support member 73 according to the third embodiment, the insertion portion 73c and the attachment portion 73a are cylindrical, and the connection portion 73b extends from the insertion portion 73c to the attachment portion 73a. It is formed in a funnel shape that gradually narrows toward the center, and the central axis in the longitudinal direction of the mounting portion 73a is eccentric with respect to the central axis in the longitudinal direction of the insertion portion.
By doing so, as shown in FIG. 14, even if the vehicle collides with the blocking bar 70 and the blocking bar 70 bends in the horizontal direction, the gap X can be secured. Contact with the sensor 90 and other devices can be prevented.

The support member 73 further includes a plurality of ribs 73d that protrude radially from the outer surface of the attachment portion 73a along the outer surface of the connection portion 73b as viewed from the central axis in the longitudinal direction of the attachment portion 73a. preferable. By carrying out like this, the intensity | strength from the attaching part 73a to the connection part 73b can be reinforced.
Here, since the material of the support member 73 is the same as that of the support member 23 according to the second embodiment, the description thereof is omitted. Similarly, it can be integrally formed in a form including the rib 73d by blow molding. According to blow molding, as shown in FIG. 11, a cavity 71dh is formed inside the rib 71d.

Furthermore, as shown in FIG. 12, a cylindrical portion 75a abutted and fixed to the inner surface of the attachment portion 73a and the cylindrical portion 75a are connected, and the radial extension extends from the cylindrical portion 75a along the inner surface of the connecting portion 73b. It is preferable to further include a reinforcing member 75 having a plurality of bent portions 75b provided and fixed in contact with each other. The material of the reinforcing member 75 is not particularly limited, but is preferably made of metal. If it is made of metal, as shown in FIG. 13, it is easy to process the end of the cylindrical body so as to be in contact with the inside of the support member by cutting radially. Examples of metals include aluminum, copper, and iron.
In order to attach the reinforcing member 75 to the inside of the support member 73, press fitting, fixing with a fixing tool, fixing with an adhesive, or a combination thereof can be used.

In addition, the said rib and a reinforcement member are not essential in the 3rd form, You may provide only one of these without these. Also in the second embodiment, ribs and / or reinforcing members may be provided.
Further, as an example of the long bag body, the example in which the long bag body 11 according to the three-layer structure is mounted is shown, but the long bag body may be one layer, two layers, or four layers or more. . However, there are usually two or three layers.

Moreover, since the protective sheet 12 can be provided like the 2nd form and the material, the effect, etc. about the protective sheet 12 are the same as that of the 2nd form, the description is abbreviate | omitted.
In addition, since the fixing method to the supporting member 73 of the elongate bag body 11 is the same as that of a 1st form, the description is abbreviate | omitted.

(3) Information display part It is preferable that the information display part for providing information with respect to a passing vehicle is provided in the surface part of the outer side elongate bag body of a blocking bar.
For example, by displaying the speed limit as “20 km”, the effect of prompting the vehicle to drive slowly and reducing the speed of entering the toll gate can be obtained. In addition, if you display “Welcome to 000”, you can express your welcome to visitors to the town, which can also be useful for revitalizing the town.
The display method of the information display unit is not particularly limited, and various methods can be employed. For example, characters or the like may be written or printed directly on the surface of the long bag body, or a method of attaching a label on which characters or the like are written may be used.

An information display part can also carry out light emission display by an LED element and / or a luminous film. By doing so, an effect of conspicuous information can be exhibited particularly at night.
If the LED element emits light, the light can be emitted with low power. Therefore, the electricity stored in the daytime can be used at night by using the solar panel. The LED element can be lit and displayed by attaching it to the surface of the long bag.
Moreover, it can also carry out light emission display with a phosphorescent coating film. The phosphorescent paint may be applied directly to the surface of the long bag body, or a label coated with the phosphorescent paint may be attached to the surface of the long bag body. Further, both the LED element and the phosphorescent coating film can be used in combination.

[2] Blocking device The blocking device includes the blocking rod and a blocking device that rotates the blocking rod via a connecting member and holds the blocking rod in a vertical state or a horizontal state.
Since the “blocking bar” described in [1] can be used as it is, the “blocking bar” will not be described.
For example, as shown in FIG. 15, the blocking device 1 includes a blocking bar 10 and a blocking device 50 that rotates the blocking bar 10 via a connecting member 51 and holds the blocking bar 10 in a vertical state or a horizontal state.
The “connecting member” is a member connected to a blocking machine that rotates the blocking bar and holds it in a vertical state or a horizontal state. For example, as shown in FIG. 9, the connecting member 51 attached to the blocking machine 50 is connected to the mounting portion 13 a of the blocking bar 10.

  When the vehicle 60 enters at a predetermined speed or less, the blocking bar 10 becomes vertical via the connecting member 51 and allows the vehicle 60 to pass. On the other hand, when approaching beyond a predetermined speed, the blocking bar 10 does not become vertical, and the vehicle 60 collides with the blocking bar 10. At that time, as shown in FIG. 10, the blocking member 10 a provided in the connecting member 51 rotates the blocking rod 10 in the traveling direction of the vehicle around the hinge portion (not shown) of the rotating member 51 a as a vehicle. Bend horizontally in the direction of travel. A collision with the blocking bar 10 can be notified to a toll staff by a sensor (not shown) that detects the rotation of the rotating member.

Hereinafter, the present invention will be described more specifically with reference to examples.
