Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gate that opens and closes a passageway through which people or vehicles enter and exit buildings, garages, grounds, etc., and particularly relates to a gate that can be opened and closed by remote control.

[Conventional technology]

Gates or shutters for the passage of goods and people can be opened and closed vertically, horizontally, and circularly (barriers), and can be powered by human power, mechanical power, electric power, or pneumatic power (for example, 6O-195495), etc.

Although each of these has its own characteristics, the issues that are of particular concern are the volume when opened, that is, when stored, and the convenience and safety when opening and closing.

[Problem to be solved by the invention]

In general, the following items are particularly required for general purpose gates.

(1) The opening/closing operation range is large: When open (when the gate is stored), K is the volume, especially when viewed from the front, @ is small.

When closed, the mechanical width of the gate shall be at its maximum.

(2) The front and back width (thickness) must be small when viewed from the front during opening and closing operations. In other words, opening and closing operations should not be an obstacle.

(3) Good appearance.

(4) Able to perform remote operation (remote control).

(5) There is no danger of falling, etc.

An object of the present invention is to provide a gate that satisfies the above requirements.

[Means to solve the problem]

(1) Multiple pairs of columnar bodies connected by beams are provided.

When the gate is open, it is folded to its minimum size, and when it is closed, external power is applied to the first column with the gate post as a support point, allowing multiple sets of columns to operate simultaneously to maximize the opening/closing range. be obtained. .

(2) All power transmission mechanisms should be housed inside beams or columns, taking care not to impair safety and aesthetics.

and the columnar bodies 3 to 1o.

The outer cylinder 21 is the outer cylinder of the first columnar body 3, and n is also the outer cylinder of the second columnar body 3.
This is the outer cylinder of the columnar body 4, and will be numbered in the same order as 32i below.

@Figures 4 to 6 show how the gate changes from the open state to the closed state. That is, Fig. 4 is fully open, Fig. 5 is half open, and Fig. 6 is fully open.
The figure is a schematic representation of the fully open position.

The inner cylinder 40 has bearing parts 41, 42, and 43, and has an inner cylinder 4o and an outer cylinder 4o. An upper bearing material and a lower bearing 45 are interposed between 1j and 21.

The inner cylinder 46 is housed inside the columnar body 4, and bearings 47 and 48 are also provided within the columnar body 4.

The output pinion 52 of the power 3ti50 is spline connected to the bearing portion 41. The bearings 53 and 54 support the pulley shafts, the pulley shaft 57 is provided within the inner cylinder 46 within the columnar body 4, and the pulley shaft 59 is provided within the inner cylinder 76 within the columnar body 5. The screws 13 are provided to connect the lower beams 11, 111 and the outer cylinder n.

The operation based on the above configuration will be described.

Figure 7 shows the pulleys 62, 64, belt 69, and pulley 65 as the lower beam 11 and 111 turn in Figure 1.
, 66.

67 is a simplified diagram showing the operation of 67. In other words, A is the pulleys 62 and 64, which cannot rotate because they are fixed by the outer cylinder 21 and the lower fixing portion 61 of the shaft 5G. B corresponds to pulleys 65, 66, and 67, which are connected by a bolt 69. On the other hand, at point B, the lower beams 11, 111 and the inner cylinder 40
．． The outer cylinder n is integrated with the screw 13 and rotates 90' to the left in the figure by the power source blade, so Boo! J65
J 66 + 67 causes the orientation to change as shown in 81. In other words, the shaft 57 of the pulley field 66.67 has moved parallel to the axis.

FIG. 8 similarly shows the movement of the boob I764, the bell) 68 and the small boob IJ 53 with respect to the 90' rotation of the lower beams 11, 111.

In this example, the pulley diameter of C is half that of A, so when the lower beam 11.111 turns, the axis of C rotates counterclockwise relative to the position of C1. That is, it can be seen that when A is fixed and C turns to the left, the axis of C further rotates 90' to the left.

Figure 9 shows the relationship shown in Figure 8 in a little more detail. When beam A in section A turns in the direction of 451 in the figure (the pulley in section A is fixed), rotation to the left occurs in section 0. This shows that beam B fixed to the C-axis rotates to the left. In Figure 9, if the diameters of pulley A and small pulley C are 2:1, α=4
It shows that β=45° when the angle is 5°.

FIGS. 10 to 13 are explanatory diagrams when the principle of FIGS. 7 and 8 is applied to the structure of a gate.

In FIG. 10, part A shows the first columnar body 3 of the gate, and part B shows the second columnar body 4. (1) Outer cylinder n is fixed, so just \90'9
0' left 2) Pulley fields 66 and 67 move in parallel (principle shown in Fig. 7) (3) Small pulley 63 rotates 90' to the left by means of a rotor (principle shown in Fig. 8) (4) Inner cylinder 46 (principle shown in Fig. 8) 1) is fixed to the small pulley 63, so the upper beam 12 connected to the inner cylinder 46 rotates 90 degrees counterclockwise (5).
゜121 changes from vertical direction to horizontal direction by turning left in the figure (work mark → - mark) In Fig. 11, part B is the second columnar body of the gate 4.0 part is the third columnar body 5 is shown. Since the inner cylinder 46 of section B rotates to the left as described above, section 0 rotates 90' to the left in the direction of arrow 81 with section B as the center via the upper beam 12 degrees 121.

(1) Since the inner cylinder 46 rotates 900 degrees to the left, the outer cylinder n is 90'
Rotate to the left and move to C1 (2) Pulley 73.75 moves in parallel (principle in Figure 7) (
3) The small pulley 74 is rotated 90' to the left by the belt 71 (principle shown in Fig. 8) (4) The small pulley 74 and the inner cylinder 76 are fixed together, so they can be rotated 90' to the left 5) As a result, the lower beam 77 connected to the inner cylinder 76
771 is a rotation from the vertical direction to the right and changes to the horizontal direction (I mark → - mark). FIGS. 12 and 13 also show a similar movement. Therefore, for all beams, the vertical direction at the time of installation is
In this figure, it rotates 90' to the right or left and changes in the horizontal direction, which indicates that the gate changes from open (reduced) to closed (extended).

In the above embodiment, an electric motor is used as the power source blade, but it is also possible to use circular arc movement of a cylinder or the like.

〔Effect of the invention〕

Consists of an outer cylinder having openings on the upper and lower cylinder surfaces, an inner cylinder rotatably supported within the outer cylinder, and a pulley shaft rotatably supported within the inner cylinder with respect to the outer cylinder or the inner cylinder. a plurality of columnar bodies, upper and lower hollow beams that protrude from the inner cylinder of one columnar body through an outer cylinder opening and are connected to the outer cylinder of an adjacent columnar body, and adjacent pulley shafts that pass through the hollow beams. an endless belt wrapped around an upper pulley, a power source for driving the inner cylinder is provided in the first columnar body fixed to a support, etc., and the pulley shaft of the first columnar body is fixed to the outer cylinder. A first-order effect is obtained.

(1) When the gate is open, the components are reduced to the geometrically possible extent, ie, the passageway can be utilized to the maximum. Also, when closed, it can be extended to its maximum length, making it extremely effective in terms of space utilization.

(2) Only the drive source is installed inside the first columnar body, and the rest of the power is transmitted mechanically and efficiently, which is superior in terms of equipment and aesthetics.

(3) Since a single driving source is sufficient, remote control is easy.
