Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a gate installed at an entrance / exit of a parking lot or at an entrance / exit of a boundary between a site and a public road or a private road around the parking lot to indicate a boundary and prevent free traffic and passage. Regarding More specifically, the present invention is
The present invention relates to an arm-type gate including an arm portion that is foldable.

[0002]

[Prior Art] The entrances and exits of garages such as private land and the entrances and exits of the boundary between the site and the public roads and private roads around them show boundaries and hinder free traffic and passage.
Conventionally, gates and shutters have been used. On the other hand, the concept of an open exterior is to provide a boundary that gives an open image and enables effective use of space, while providing psychological deterrence as a boundary that is difficult to enter, rather than the conventional noisy boundary. Is being adopted in recent years.

By the way, there is a gate installed at an entrance / exit of a parking lot, for example, to give a psychological image as a boundary. Such a gate,
As shown in FIG. 11, the shutoff unit 102 is configured so that the shutoff unit 102 is rotatable between a shutoff position 103 and a retracted position 104, and a shutoff unit hung by a wire or the like as shown in FIG. There is an up-and-down type gate 106 configured so that 105 is retracted upward when it is not cut off and descends downward when it is cut off.

[0004]

However, the gate 101 of the breaker type requires a sufficient space above because the breaker 102 projects upward when it is not blocked. In addition, it cannot be said that the appearance of the blocking portion 102 protruding upward is aesthetically excellent, and it is not appropriate to apply the gate 101 to the boundary of a house or the like. In addition, in the lifting type gate 106,
Since the blocking unit 105 retreats upward and occupies the space when the circuit is not blocked, the upper space cannot be effectively used.

Therefore, the present invention provides an open image while providing psychological deterrence as a boundary that is difficult to enter.
Moreover, it is an object of the present invention to provide an arm-type gate capable of effectively utilizing a space.

[0006]

In order to achieve the above object, an arm type gate according to the invention of claim 1 is provided with an arm portion configured to be foldable, and a gate pillar for supporting the arm portion. The arm portion has a first link, a second link that connects the middle of the first link and a gate pillar by a rotating pair, and a crank portion. The crank portion rotatably supports the end of the first link and the gate pillar. And a third link rotatably connected to.

Therefore, when the second link is rotated away from the gate pole, the first link receives the movement of the second link.
The third link, which is connected via the link, also rotates away from the gate post. Further, due to the rotation of the second link and the third link, the first link is supported by the crank portion of the third link such that the tip of the first link projects from the gate pole, while the third link and the second link are supported. Rotate.
With the above operation, the arm portion extends horizontally from the gate pole. On the other hand, when the second link is rotated so as to approach the gate pole in the opposite direction to the case where the arm portion is extended, the third link also rotates so as to approach the gate pole via the first link. Further, in conjunction with the rotation of the second link and the third link, the first link rotates with respect to the second link and the third link so as to follow the gate post. As a result, the arm portion is in the retracted state while being folded. In this way, by extending the arm part to create a passage blocking state (when blocked) and by folding the arm part to create a passage permitted state (when not blocked), the space occupied by the arm-type gate is reduced. Minimize the space and effectively use the space.

According to a second aspect of the present invention, in the arm type gate according to the first aspect, the gate post is configured to have a space for accommodating the folded arm portion.
In this case, since the folded arm portion is housed in the gate pole, the arm portion does not occupy the space around the gate pole when the door is not blocked.

According to a third aspect of the invention, in the arm type gate according to the first or second aspect, the arm portion is provided with a drive source. In this case, the arm can be expanded and contracted by the function of the drive source without manual labor.

BEST MODE FOR CARRYING OUT THE INVENTION The structure of the present invention will be described below in detail based on the embodiments shown in the drawings.

1 to 4 show an embodiment of the arm type gate of the present invention. Arm type gate 1 of this embodiment
Includes an arm portion 2 configured to be foldable, and a gate post 3 that supports the arm portion 2. And the arm part 2
Has a first link 4, a second link 5 that connects the first link 4 and the gate post 3, and a crank portion 7.
Thus, the end of the first link 4 is rotatably supported, and the third link 6 rotatably connected to the gate post 3 is configured to be foldable.

The gate post 3 supports the arm portion 2. In the case of the present embodiment, the gate post 3 forms a box shape having a space 8 large enough to accommodate the folded arm portion 2 therein, and is constructed on a foundation or the like. Has been done. This box-shaped gate post 3 is closed on all the remaining surfaces except the surface that is opened to allow the arm section 2 to move in and out, and the folded and housed arm section 2 is exposed to wind, rain, and sunlight. To prevent. This gatepost 3
The material is not particularly limited, and may be formed into a rectangular column by sheet metal, or may be formed of an aluminum die-cut material, an extruded material, a cast product, or the like. Of course, when it is not necessary to house the arm portion 2, a pole-like support may be used. The gate post 3 may not only support the arm portion 2, but may also be provided with an external light, a mail / newspaper receiver, or the like, if necessary.

The arm portion 2 is constructed so as to be foldable by three links 4, 5, 6. Each link 4, 5, 6
Is constituted by a round pipe made of aluminum in the case of the present embodiment. The links 4, 5, 6 and the gate post 3 are connected by joints (connecting members) that form a rotating pair. Each link 4,
The members 5 and 6 are connected to each other by a connecting member (joint) forming a hinge so as to be connected to each other by a pair. As the material of the connecting member, it is preferable to use a weather-resistant material that does not rust, is lightweight and has excellent mechanical strength, such as polyacetal resin, polypropylene resin, or aluminum die casting. In the present embodiment, this joint is, for example, a male joint 27, 12 having one protrusion.
And a hinge connection comprising female joints 21 and 13 split into two forks for receiving the projections of the male joint, and shafts 11 and 14 serving as rotation centers that rotatably connect to each other through the overlapped portions. It is a structure.

The rotating pair that connects the second and third links 5 and 6 and the gate post 3 includes the upper link support portion 1 that includes the rotating shafts 17 and 20 and a bearing member that rotatably supports the rotating shafts 17 and 20.
6 and the lower link support portion 19. Here, the upper link support portion 16 is attached and fixed by a screw from the outside of the gate pole 3 so that the bearing portion 16 a projects into the gate pole 3 from a hole provided near the upper end of the gate pole 3. Further, the lower link support portion 19 is positioned below and slightly deeper than the upper link support portion 16 so that the bearing portion 19 a projects into the gate pole 3 from the hole provided in the gate pole 3. It is fixed with screws from the outside.

In the case of this embodiment, the joints can be disassembled as required by adopting bolt and nut fastening means as the shafts 11 and 14 of the hinge connection structure. For example, as shown in FIGS.
A female joint 13 fixed to the base end side of the link 4 with screws or the like and a male joint 12 at the tip of the second link 5.
And are connected by a bolt (shaft) 14 so as to be disassembled, and are rotatably attached. Further, the female joint 21 at the tip of the third link 6 and the male joint 2 at the base end of the first link 4
It is rotatably attached to 7 by a bolt (shaft) 11 so as to be disassembled. In this embodiment, in order to utilize existing structural materials such as pipes, each joint adopts a method in which it is configured with a separate member from the link, gate post, etc. and fixed with screws, etc. It may be done.

A cap 10 made of resin or metal is attached to the tip of the first link 4 so as to close the end of the pipe, for example, by pushing or pressing. A male joint 27 is fixed to the other end of the first link 4 by screwing or the like. This male joint 2
A joint 21 forming the crank portion 7 of the third link 6 is attached to the shaft 7 via a rotary shaft 11 so as to be freely rotatable in the XZ plane.

A joint 15 is fixed to one end of the second link 5 by screwing or the like. The joint 15 has a hole having a rectangular cross section, and penetrates a rectangular cross section shaft portion 17a of a rotary shaft (motor drive shaft) 17 rotatably supported by a first link support member 16 attached to the gate post 3. It is fitted so that it cannot rotate. Therefore, it is supported so as to be able to receive the rotation of the motor 22 and rotate together with the shaft 17 in the XZ plane. A male joint 12 is fixed to the other end of the second link 5 by, for example, screwing. This male joint 12 has a connecting member 13
Are mounted via a rotary shaft 14 so as to be freely rotatable in the XZ plane. The connecting member 13 is fixed to a portion of the first link 4 near the base end side by, for example, screwing. Note that the point at which the connecting member 13 is fixed on the first link 4 is, for example, in the present embodiment, when the arm portion 2 is folded, the rotating shaft 17 of the first link supporting member 16 and the first link 4 are. It is set so that the heights in the Z direction of the tips of the are the same (see FIG. 2).

A substantially L-shaped joint 18 is attached to the base end of the third link 6, and is rotatably supported by a rotary shaft 20 constituting a second link support member 19 via the joint 18. Further, a substantially L-shaped joint member 21 is provided on the tip end side of the third link 6 to configure the crank portion 7. For example, in this embodiment,
Although the substantially L-shaped joint member 21 is attached to the tip of the third link 6 by screwing or the like to form the crank portion 7, the present invention is not limited to this, and the crank portion 7 is formed in the third link 6 by, for example, integral molding. May be.

Further, in this embodiment, a motor 22 is provided as a drive source for rotating the second link 5 around the rotary shaft (motor drive shaft) 17. This motor 22
For example, it is preferable to use a geared motor having a reduction gear built therein. The motor 22 is installed outside the gate post 3 as shown in FIG. 9, and the tip end of the drive shaft 17 is attached to the wall surface of the gate post 3 facing the bearing portion 1 of the upper link support portion 16.
It is rotatably supported by 6a. The rectangular cross-section shaft portion 17a of the motor drive shaft 17 and the corresponding hole of the joint 15 are not limited to flat surfaces, and may be splines, gear shapes, connecting keys, or the like. The rotation of the motor 22 causes the joint 15 to rotate coaxially with the rotation shaft 17, and accordingly, the second link 5 connected to the joint 15 rotates about the rotation shaft 17. Since the arm-type gate 1 is generally used outdoors, it is preferable that the motor 22 be driven by a solar cell that can be charged by solar energy, for example.

Further, in this embodiment, the hole provided on the joint 12 side for passing the rotary shaft 14 is the elongated hole 23. Then, for example, as shown in FIG. 10, the inside of the joint arm 12 is hollowed out, and the piston member 24 and
A biasing member 26 such as a coil spring and a fixing member 25 are built in so as to rotatably support the rotary shaft 14 while constantly biasing it in one direction. The piston member 24 is
It is accommodated inside the hollowed out joint arm 12 so as to be linearly movable. The fixing member 25 is fixed by screwing or the like with the biasing member 26 interposed between the fixing member 25 and the piston member 24. The tip of the piston member 24 is formed into a curved surface so that it can contact the rotating shaft 14. As a result, the piston member 24 biases the rotary shaft 14 toward one end of the elongated hole 23. On the other hand, during the expansion and contraction operation of the arm portion 2, the rotation shaft 14 can be moved in the elongated hole 23 against the biasing force of the piston member 24, if necessary, due to the posture of the arm portion 2. As a result, when the angle between the first link 4 and the second link 5 is broken, relief is provided so as to easily pass over the dead point, and the arm portion 2 can be smoothly expanded and contracted. Since the sum of the distances / spacings of the rotation shafts (pins) 17 and 14 and 11 is longer than the distances / spacings of the rotation shafts (pins) 17 and 11, the second link 5 rotates to separate from the third link 6. However, a long hole that is as long as the above difference in distance is required.

The length of each link 4, 5, 6 and the rotary shaft 17,
The position of 20 and the position of the rotating shaft 11 in the crank portion 7 are set so that the arm portion 2 can be folded as compactly as possible. That is, in a state where the arm portion 2 is folded, the third link 6 is located near the gate post 3, the second link 5 is located near the third link 6, and the second link 5 is located near the gate post 3.
The first links 4 are set so as to be located near the links 5 (see FIG. 2).

Further, when the arm portion 2 of the joint 15 is folded, a stopper 15a, which is a concave portion that abuts against and supports the first link 4, is provided on the surface of the joint 15 that closely faces the tip of the first link 4. When the part 2 is folded, the distance between the second link 5 and the first link 4 is kept constant, and the first link 4 and the second link 5 are lateral (ZX).
It is considered to prevent the deviation in the direction orthogonal to the plane). Further, near the joint 27 at the base end of the first link 4, there is provided a stopper 9 that projects toward the second link 5 when the arm 2 is extended,
The recess 9a facing the second link 5 contacts the second link 5 so that the first link 4 and the second link 5 are kept at a constant distance and the first link 4 and the second link 5 are mutually separated. Care is taken to prevent lateral displacement (direction orthogonal to the ZX plane). Furthermore, although not shown, a stopper may be provided to keep the distance between the third link 6 and the second link 5 constant when the arm portion 2 is folded. In this way, the stopper portions 9a, 1
When 5a is installed, by applying power (for example, motor rotational force) to the shaft 17, the first link 4 and the second link 5 collide with each other due to, for example, the inertia of rotation accompanying the extension and contraction of the arm portion 2. This is avoided, and when the arm is extended, the stopper 9 near the shaft 11 hits the second link 5 to prevent rotation, and its shape is easily maintained.

Arm type gate 1 constructed as described above
Operates as follows, for example. First, in order to change the state shown in FIG. 2 in which the arm portion 2 is folded and the gate is opened to the state shown in FIG. 1 in which the arm portion 2 is extended and the gate is closed, the motor 22 rotates the rotary shaft 17 around the center. Second link 5
Is rotated away from the gate post 3. Due to the rotation of the second link 5, the third link 6 also rotates around the rotation shaft 20 and away from the gate post 3. Further, according to the movements of the second link 5 and the third link 6, the first link 4 is rotated about the shafts 11 and 14, respectively, and the distal end side is projected so as to be separated from the gate post 3. The second link 5 and the third link 6 while being supported by the crank portion 7 of
Rotate against. With the above operation, the arm portion 2 is in a state of extending horizontally from the gate post 3.

On the other hand, in order to change the arm extended state shown in FIG. 1 to the arm folded state shown in FIG. 2, the second link 5 is rotated by the motor 22 about the rotary shaft 17 so as to approach the gate post 3. Due to the rotation of the second link 5, the third link 6 also rotates about the rotation shaft 20 via the first link 4 so as to approach the gate post 3. Furthermore, the second link 5
The rotation of the third link 6 causes the first link 4 to rotate and move on the XZ plane such that the tip end of the first link 4 approaches the rotating shaft 17 (closer to the second link 5). By the above operation, the arm part 2 is folded and housed in the internal space 8 of the gate post 3.

As described above, in the arm-type gate 1 of the present invention, the arm portion 2 can be compactly folded when it is not cut off, and it does not occupy a large space. Therefore, it is possible to give an open image and effectively use the space while retaining the psychological image as the boundary. Further, since the folded arm part 2 is housed inside the gate post 3, the arm part 2 does not project from the gate post 3 and become an obstacle, and the appearance is the same as a normal gate post, so it has a beautiful appearance. It doesn't hurt.
In addition, the gate post 3 protects the arm portion 2 from wind and rain when the door is not cut off. Further, the bending and stretching of the arm portion 2 in the present embodiment can be operated by, for example, a switch that controls the motor 22 and is simple.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, the driving means is not necessarily limited to the one using the motor 22. The drive unit may be configured by, for example, a handle and a gear so that the second link 5 is manually rotated about the rotation shaft 17. Further, in the above-described embodiment, the second link 5 is rotated about the rotation shaft 17, but the present invention is not necessarily limited to this.
In some cases, the third link 6 may be rotated around the rotation shaft 20. In this case, for example, the first
A biasing means such as a spring is provided between the link 4 and the second link 5, or a weight is provided near the tip of the first link 4, so that the first link 4 is rotated before the rotation of the third link 6. It is preferable that the tip end projects from the gate post 3.
Thereby, the arm portion 2 can be surely bent and extended even by rotating the third link 6 with respect to the gate post 3.

It is needless to say that the function and decoration performed in a general gate post may be added to the gate post 3, for example, by providing an electric light above the gate post 3.

[0028]

As is apparent from the above description, according to the arm type gate of the first aspect, the first to third links are rotated in association with each other by the rotation operation of the third link or the second link. By doing so, the arm part is extended so that it projects horizontally from the gate post, or it is folded so that it is pulled toward the gate post, so the gate is opened and closed, so the arm part should be opened when the passage is not blocked and not blocked. It can be folded compactly and does not occupy a large entrance space. Moreover, the height of the arm portion when the arm portion is folded (when the gate is open) can be made to correspond to a link length that is about half of the required extended length of the arm portion, and each link is Since they are arranged in parallel with a minimum gap, they do not take up space in the depth direction (gate width direction), so the storage space can be made compact. Therefore, according to the present invention, it is possible to give an open image and effectively use the space while providing psychological deterrence as a boundary that is difficult to enter.

According to the second aspect of the present invention, when the passage is not blocked and is not cut off, the arm portion does not protrude from the gate pole and become an obstacle, and the appearance is the same as a normal gate pole. Since it is only the gatepost, it does not spoil the aesthetics. Moreover, when the arm portion 2 is housed in the gate pole, it also protects from wind and rain. Therefore, it is possible to further enhance the effect of the open exterior structure, which gives an open image and can effectively use the space.

Further, according to the third aspect of the invention, since the arm portion is provided with the drive source, the arm portion can be expanded and contracted, that is, the gate can be opened and closed by the function of the drive source without manual operation.
