Description

  The present invention relates to a gate which is installed in front of a house and can be opened and closed by moving up and down. However, the use of the gate is not limited, and can be installed as an entrance of a parking lot, for example.

A space (space) where a car can be parked is provided in the house, but there are various forms of this parking space.
For example, in the case of a garage configured as a covered space, an entrance is provided with a shutter that opens and closes. Therefore, the covered garage becomes large and the construction cost is considerably increased, and the rear house is hidden by being located in front of the house. Many garages have only a roof and no shutters on the front.

A telescopic gate may be installed as the entrance gate of the parking space. The telescopic gate employs a link mechanism so that it can be expanded and contracted in the horizontal direction, and must be opened and closed by hand when entering and leaving the vehicle, which is cumbersome to operate. And it is difficult to install this telescopic gate in areas where it snows in winter and there is snow.
Of course, it is not as large as a large garage with a roof, but when the gate is extended, the front of the house is blocked, and the scenery is damaged especially if the house has a garden.

On the other hand, sliding door gates are also known, but like the above-mentioned telescopic gates, they must be opened and closed by hand when entering and exiting the vehicle, and in areas where there is snow to slide open and close along the floor rails It cannot be installed.
Also known is a flip-up type gate with a grid-like door mounted so that it can swing around an axis provided at the upper end of each side and configured to swing upward when the car enters and exits. Yes.
Even with this flip-up type gate, the front of the house is blocked, and as a result, the appearance of the house is impaired.

“Extensible gate” according to Japanese Patent Application Laid-Open No. 2015-63844 is an extendable gate capable of adjusting the inclination of a moving vertical frame despite a plurality of pantograph mechanisms arranged vertically.
A plurality of pantograph mechanisms that are configured to be stretchable by combining a plurality of right-up and down-right inclined links arranged in the left-right direction are arranged vertically so as to straddle the moving side ends of the plurality of pantograph mechanisms. It is a telescopic gate with a moving vertical frame.

The “sliding door gate” according to Japanese Patent Application Laid-Open No. 2006-191220 is a sliding door that can simplify the tilting operation of the door body relative to the suspension base and the adjustment operation of the front and rear position.
The sliding door includes a suspension support, a guide roller, and a door. The guide roller is rotatably supported by the suspension support through a shaft-shaped attachment member. The door body has a fitting portion that can be fitted to the guide roller, and the guide roller is supported by the suspension support body so as to be movable when the guide roller is fitted to the fitting portion. The attachment member is provided on the hanging support so that the amount of protrusion to the door body can be adjusted. And the protrusion amount is comprised so that adjustment is possible from the opposite side of a door body on both sides of a suspension base support body.

  Thus, even if it is called a gate, there are various forms, and the above problems remain. The problems to be solved by the present invention are these problems, and provide a gate that can be lifted and lowered that does not impair the landscape of a house and that is simple in structure and can be constructed at low cost.

  The gate according to the present invention is composed of a vertical frame standing upright from the ground, a portal frame that frames the upper frame, and a lifting plate. The elevating plate is a horizontally long rectangle and is mounted across both vertical frames, and can be moved up and down along the vertical frame. Therefore, guide rollers are attached to both ends of the elevating plate, and a guide groove is provided in the vertical frame. The guide roller can move in the vertical direction along the guide groove.

  A motor is attached to the upper frame, and when the motor is driven to rotate, the elevating plate can be moved up and down along the vertical frame. Therefore, a belt extends along the vertical frame and is connected to the lifting plate, and the belt is wound around a pulley that is rotated by a motor. Therefore, the elevating plate can be moved up and down through the belt by the rotation of the motor. However, the lifting means is not particularly limited.

  In the lift gate of the present invention, the lift plate can be moved up and down along both vertical frames of the gate-shaped frame. The elevating plate is normally lowered and is in contact with or close to the ground so that it can be raised when a car or the like enters or exits. The elevating plate is a rectangular shape that is elongated to the left and right. Therefore, when the elevating plate is lowered, a large space is formed between the upper frame of the frame, and when the elevating plate is raised, A large space is formed between the ground.

Therefore, the house and the garden are not blocked by the gate, and there is no possibility that the scenery is damaged. In addition, the gate has a simple structure in which an elevating plate is simply attached to the frame. Therefore, the construction cost is low, and it can be easily installed even in a narrow residential land.
The gate lift plate does not need to be moved up and down by a motor and manually lifted and lowered, and can be used as a garage gate because it can be operated by a remote controller while on the vehicle.

The gate front view of the state where the raising / lowering plate is falling. The gate front view of the state where the raising / lowering plate is rising. The example which shows the raising / lowering means for raising / lowering the raising / lowering plate. The example which shows the guide means of a raising / lowering plate. The AA cross-sectional enlarged view of FIG.

  FIG. 1 shows an embodiment of a gate that can be raised and lowered according to the present invention. In FIG. 1, 1 denotes a frame, and 2 denotes a lifting plate. The frame 1 has a gate shape that frames both the vertical frames 3 and 3 and the upper frame 4, and the elevating plate 2 can move up and down along the vertical frames 3 and 3. The lifting plate 2 shown in the figure has a structure in which a plurality of horizontal bars 5, 5... Are connected by vertical bars 6, 6,. Considering the balance with the house, it is configured to have an appropriate design.

  Since the gate shown in FIG. 1 is disposed at a position where the elevating plate 2 is lowered, a large space 7 is formed between the gate and the upper frame 4. Therefore, when the gate is installed in front of the house, the space 7 does not block the house, and the house does not become shaded by the gate. Furthermore, there is no loss of ventilation.

  FIG. 2 shows a case where the elevating plate 2 is raised to the position of the upper frame 4. If the gate is used for a parking lot, the elevator plate 2 is in the raised position as shown in the figure when the vehicle enters and exits. Therefore, a large space 9 is formed between the lifting plate 2 and the ground 8 and does not block the house. Thus, even if the raising / lowering plate 2 is descending or rising, the formed spaces 7 and 9 are large and the landscape of the house is not impaired, and the house is shaded at the gate. There is no such thing as that, and there is no worse ventilation.

By the way, the raising / lowering plate 2 is not lifted by hand, but a motor is attached, and the raising / lowering plate 2 can be moved up and down by driving the motor. FIG. 3 shows a specific example of the lifting means of the lifting plate 2. A motor 10 is attached to the upper frame 4, and a belt 12 is wound around a pulley 11 that is rotated by the motor 10.
The belt 12 is connected to a guide member extending from the elevating plate 2. When the belt 12 is wound around the pulley 11, the elevating plate 2 is raised, and conversely, the elevating plate 2 is unwound from the pulley 11. You can descend.

  A coil spring 13 is attached to a shaft extending from the motor 10. The coil spring 13 can manually move the lifting plate 2 up and down when the motor 10 does not start due to a power failure. The coil spring 13 is urged by a spring force in the direction in which the elevating plate 2 is raised, and the elevating plate 2 can be easily lifted by hand by using the spring force urged by the coil spring 13.

FIG. 4 is a specific example showing a case where the tip of the elevating plate 2 is guided by the vertical frame 3. A guide portion extends outward from the tip of the lift plate 2, and a guide roller 14 attached to the tip is loosely fitted in a guide groove formed in the vertical frame 3.
The belt 12 extends from above, and the lower end of the belt is connected to the guide portion of the elevating plate 2.

FIG. 5 shows an AA cross-sectional enlarged view in FIG. An arm 15 is attached to the tip of the elevating plate 2 and extends to the back side, and a guide portion 16 that extends outward is attached to the tip of the arm. A guide roller 14 is rotatably supported at the tip of the guide portion 16.
The vertical frame 3 is provided with a partition wall 18 to form a guide groove 17, and the guide roller 14 is loosely fitted in the guide groove 17.

  Further, a guide groove 20 is also provided on the inner wall 19 of the vertical frame 3 having a quadrangular cross section and extends in the vertical direction, and the guide portion 16 is loosely fitted in the guide groove 20. As described above, since the elevating plate 2 is guided by the vertical frame 3 at the two locations of the guide roller 14 and the guide portion 16, it can be restrained without causing bending stress to the arm 15. Moreover, since the elevating plate 2 is provided with guide rollers 14 and 14 at the lower end portion and the intermediate portion thereof and is guided by the vertical frame 3, the elongating elevating plate 2 is not inclined to the left and right.

Since the guide roller 14 is not provided at the upper end of the tip of the elevating plate 2, the upper edge 22 of the elevating plate 2 can coincide with the upper surface of the upper frame 4 when it is raised, and below the elevating plate 2. The formed space 9 becomes larger.
Further, the vertical frame 3 has a two-piece structure, and in order to make it easy to loosely fit the guide roller 14 in the guide groove 17, a separable auxiliary wall 21 is provided on the front side, and the guide roller 14 is loosely fitted. It is configured so that it can be attached later.
