Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a flip-up door that is opened and closed by vertically pivoting the door body.

(Prior Art) Conventionally, doors such as gates have been commonly used, such as double-door doors, sliding doors that slide horizontally, and telescoping doors that can be opened and closed in the horizontal direction.

However, double-folding doors create an unusable space (dead space) for opening and closing the door.
In addition, sliding doors require a retracting space to pull the door in, and retractable doors leave a considerable folded width when the door is open, reducing the usable frontage. The problem is that the available space is limited.

On the other hand, among known doors, a flip-up type door as shown in FIGS. 6 and 7 is known (Japanese Patent Publication No. 57-53507). The flip-up door of this known example has a rectangular plate-shaped door face body 101 and a pillar 10.
It is fixed to the tip of a support arm 103 which is pivotally mounted (shaft 104) at a predetermined height position of 2, so that the door face body 101 can be pivotally opened and closed in the vertical direction together with the support arm 103.

However, in this known flip-up door, the fulcrum (shaft 104) supporting the support arm 103 is located at a fairly high position on the support 102, and when the door face 101 is opened or closed, the door face 101 (especially The lower end 101a) protrudes forward by a considerable width Z and pivots, so that the door face body 101 is positioned inward by the protrusion width Z from the outer surface of the entrance/exit component Y such as a gatepost or block wall. In that case, there is a problem that the effective space on the premises becomes smaller, and a gap S may occur between the inner corner of the entrance component Y and the front surface of the door face piece 101. The gap S must be filled with fillers X and X.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention is designed to prevent the door face body from protruding forward from the closed state of the flip-up type door when the door is opened/closed (when the door swings), or to The purpose is to make the width smaller.

(Means for Achieving the Object) The flip-up door of the present invention is provided with the tip of the main support arm which is pivotally connected to the support column so as to be able to pivot vertically at an appropriate height position. The tips of the auxiliary support arms juxtaposed along the main support arm are pivoted to two positions appropriately spaced apart in the door height direction on the door face body so as to be able to pivot relative to each other, while the main support arm and the an auxiliary support arm by a connecting rod at each proximal position of the main support arm and the auxiliary support arm, one end of the connecting rod and the main support arm also connecting the other end of the connecting rod and the auxiliary support arm. are pivotally connected to each other so as to be able to pivot freely relative to each other, and a pivot joint between the main support arm and the door face body, a pivot joint between the auxiliary support arm and the door face body,
The pivot portion between the main support arm and the connecting rod, and the pivot portion between the auxiliary support arm and the connection rod are connected to each other so as to be located at each top of the parallelogram, and the proximal end portion of the auxiliary support arm is connected. The auxiliary support arm is supported by a guide device so that it can pivot vertically and slide only in a direction perpendicular to the ground surface.

(Function) The flip-up door of the present invention has a door face, a main support arm, an auxiliary support arm, and a connecting rod so that their respective pivot points (four in total) are located at each top of a parallelogram. Since the joints are connected together, the parallelogram formed by connecting the respective pivot joints can be deformed.
Furthermore, the guide device allows the base end of the auxiliary support arm to slide only perpendicularly to the ground surface, so that when the door face body is pivoted upward from the downward closed state, the main support arm While the main support arm pivots upward around the column pivot point, the base end of the auxiliary support arm can only move in the vertical direction. The angle formed between the door face and the door face becomes smaller than the original angle, and the lower end of the door face is pulled inward and rotated.

(Embodiments) Several embodiments of the present invention will be described with reference to FIGS. 1 to 5. FIGS. 1 and 2 show the first embodiment, and FIGS. 3 to 5 show the first embodiment. The flip-up doors of second to fourth embodiments are shown, respectively.

The flip-up door of the first embodiment shown in FIGS. 1 and 2 is used for gates, etc., and has a horizontal door face plate 1 having a predetermined height (for example, about 100 cm).
The main support arms 3, 3 are pivotally connected to the left and right support columns 2, 2 at appropriate height positions so as to be able to pivot in the vertical direction, respectively, and The main support arm 3 and the auxiliary support arm 4 are connected by a connecting rod 5 at their proximal ends, and the auxiliary support arm 4 is The proximal end 4b of is pivotally connected (pivot part 16) to an elevating body 8 that is guided by a guide device 6 so as to be slidable only in the vertical direction.

The door face 1 is constructed by arranging a large number of vertical lattices 19 within a horizontally long rectangular frame 18.

The pair of left and right pillars 2, 2 are made of hollow square pipe-shaped material. Further, each of the pillars 2, 2 is erected at a position spaced from the door face body installation position by the length L of the main support arm 3 on the inside of the premises. still,
The distance between the two pillars 2, 2 is approximately the same as the horizontal length of the door panel 1.

Appropriate height position of each support 2, 2 (for example, ground surface F
The proximal ends 3b, 3b of the main support arms 3, 3 are pivotally attached (pivot part 15) to the upper and lower positions of the main support arms 3, 3, respectively. It can pivot freely in any direction. This main support arm 3
The length L (Fig. 2) is the length of the door face piece 1 as described later.
The height of the door face body 1' is designed to be slightly larger than the height of a person's back when it is turned upward as shown by the chain line 1' (the length L of the main support arm 3).
For example, about 90 to 100 cm is appropriate).

One reinforcing rod 31 is constructed and fixed at the tips 3a, 3a of each main support arm 3, 3, respectively.
When the tips 3a, 3a of the main support arms 3, 3 are connected and fixed together by the reinforcing rod 31 in this way, twisting becomes less likely to occur when the door face body 1 is turned up and down.

In this first embodiment, each of the auxiliary support arms 4, 4 has a length M that is slightly shorter than the length L of the main support arm 3.
(for example, about 80 to 90 cm).

The tips 3a, 3a of the main support arms 3, 3 are pivoted via brackets (pivot parts 11, 11) at positions near the upper end of the back side of each side frame of the frame 18 in the door face body 1. has been done. This pivot joint 11
is a position such that the height H from the lower end 1a of the door face body 1 to the pivot joint 11 is approximately the same as or slightly smaller than the length L (90 to 100 cm) of the main support arm 3 (for example, H= 80-90cm).
Note that if the height H from the lower end 1a of the door panel 1 to the pivot portion 11 is greater than the length L of the main support arm 3,
Door face piece 1 when the lower end 1a of the door face piece 1 is in the closed state when the door face piece 1 is turned upward (opening the door)
The possibility of protruding outward is greater than the position of
It is preferable that the height H is approximately the same as or slightly smaller than the length L. In addition, if the height H is extremely small (for example, about 50 cm), the function as a door will deteriorate, and if the length L of the main support arm 3 is made extremely large (for example, about 150 cm) with respect to the height H, then the door function will deteriorate. When the door face piece 1 is flipped upward as shown by the chain line 1', a problem arises in that the hand cannot reach the door face piece 1, so the height H is set to 80 to 90 cm and the length L is set to 90 to 100 cm. It is preferable to do so.

In this first embodiment, the tips 4a, 4a of each of the auxiliary support arms 4, 4 are connected to the main support arm tips 3a, 3a and the door panel 1 on the back side of each side frame of the frame 18 of the door panel 1. Appropriate height (for example, 10 cm) from the pivot joint 11
They are pivoted (pivot parts 12, 12) via brackets at a lower position by a certain degree.

Further, each of the main support arms 3, 3 and each of the auxiliary support arms 4, 4 are connected by a connecting rod 5 at their base ends 3a, 4a, respectively. That is, one end (upper end) 5a of the connecting rod 5 and a position near the proximal end of the main support arm 3 are pivotally connected by a shaft (pivot part 13), and the other end (lower end) 5b of the connecting rod 5 and the auxiliary support Base end 4 of arm 4
b is similarly pivotally mounted on a shaft (pivot portion 14). Also, the pivoting portion 1 between the main support arm tip 3a and the door face body 1
1. Pivot connection part 1 between auxiliary support arm tip 4a and door face piece 1
2. The pivot joint 13 between the upper end 5a of the connecting rod 5 and the main support arm 3, and the pivot joint 14 between the lower end 5b of the connecting rod 5 and the auxiliary support arm 4 are connected to the respective pivot joints 11, 12,
13 and 14 are positioned at the tops of the parallelogram, and by mutually shifting the main support arm 3 and the auxiliary support arm 4 in the length direction, the door face body 1 and the main support arm 3 (or auxiliary support arm 4)
It is now possible to change the angle between the two. Moreover, each of the four pivot parts 11, 12, 13,
In this first embodiment, the main support arms 14 are positioned at the tops of the substantially rectangular shape when the main support arms 3 are in a horizontal position. In this way, each pivot point 1
1 to 14 are positioned at the top of each substantially rectangular shape. When the door face 1 is rotated upward, the door face 1 will be in the closed state as shown in FIG. 2. It can be prevented from protruding outward beyond position 1. If, among the four pivot joints 11 to 14, the two pivot joints 12 and 14 that pivotally connect both ends of the auxiliary support arm 4 when the main support arm 3 is in a horizontal position, Two pivot joints 1 that are pivotally connected at both ends (the proximal end is closer to the end)
When the door face 1 is positioned deviated from the positions 1 and 13 toward the support column 2, when the door face 1 rotates upward, the lower end 1a of the door face 1 protrudes outward from the position of the door face 1 when the door face 1 is in the closed state. There is a possibility.

The base end 4b of the auxiliary support arm 4 is an elevating body 8 that can be slid only in the vertical direction by a guide device 6.
It is pivotally connected (pivot part 16) to the shaft. This first
In the embodiment, a pivot portion 16 between the base end 4b of the auxiliary support arm and the elevating body 8, and a joint portion 16 between the base end 4b of the auxiliary support arm and the connecting rod 5 are shown.
A common shaft is used for the pivot portion 14 and the lower end 5b. In other embodiments, the pivoting portion 14 between the auxiliary support arm 4 and the lower end 5b of the connecting rod 5 is connected to the auxiliary support arm 4.
It may be provided at a position separated from the proximal end 4b by an appropriate length toward the distal side (no problem will arise functionally even if a common shaft is not used for both the pivot parts 14 and 16).
Also, between the pivot joint part 16 which pivotally connects the base end 4b of the auxiliary support arm 4 and the guide device 6 (elevating body 8), and the pivot joint part 15 between the base end 3b of the main support arm 3 and the column 2. The horizontal distance W between the two pivot parts 16,1
It is set to be approximately equal to the vertical spacing T between 5 (for example, 10 cm each). In this way, as shown in FIG. 2, the main support arm 3 and the auxiliary support arm 4 can pivot up and down within an angle range of 90 degrees from the horizontal position to the vertical position.

In this embodiment, the guide device 6 that guides the elevating body 8 is constructed by forming a vertical guide groove 61 in the hollow support 2, and the elevating body 8 moves vertically within the vertical guide groove 61. It only allows it to slide.

The elevating body 8 is provided with a protruding rod 81 that protrudes diagonally upward on the side of the door face body 1.
The proximal end 4b of the auxiliary support arm 4 is pivotally attached to the distal end 81a of the auxiliary support arm 4.

Support devices 7, 7 capable of supporting the door face body 1, the main support arm 3, and the auxiliary support arm 4 at arbitrary height positions are provided in the spaces within the columns 2, 2.
In this embodiment, this support device 7 employs a telescopic cylinder (gas-filled damper) 71 that is always biased in the direction of extension, and the cylinder rod 71
The cylinder rod 71a is installed with its end a facing upward and the tip of the cylinder rod 71a fixed to the lower end of the elevating body 8. Further, this telescopic cylinder 71 is designed so that the urging force in its extension direction and the total weight of the door face body 1, main support arm 3, auxiliary support arm 4, connecting rod 5, etc. are balanced. By providing the support device 7 in this way, the door face 1 can be opened and closed (swiveled in the vertical direction) with a small operating force, and the door face 1 can be lifted to a desired height and then released. Even if the door face body 1 does not move up and down.

To explain the usage and function of the flip-up door of the first embodiment shown in Figs. 1 and 2, when closing the entrance/exit, the main support arms 3, 3 and the auxiliary support arms 4, 4 are moved downward to the horizontal position. to maintain the door face piece 1 in a closed state. In addition, when the door face piece 1 is in the closed state, the door face piece 1 is maintained in a vertical position with respect to the ground surface F, and the pivot joint 11 between the main support arm 3 and the door face piece 1, the auxiliary support arm 4, Pivot part 1 with door face piece 1
2. Pivot joint 13 between main support arm 3 and upper end of connecting rod 5;
and a pivoting portion 14 between the auxiliary support arm 4 and the lower end of the connecting rod 5
The four pivot joints are located at the four tops of a horizontally long rectangle, respectively. When opening this flip-up door, the door face plate 1
Alternatively, if you hold the main support arm 3 (or auxiliary support arm 4) and manually push it up by an angle of 90°, the door face body 1, main support arm 3, and auxiliary support arm 4 will be moved to the chain lines 1', 3', and 4, respectively. It is now maintained in an upwardly lifted position as shown by ''. At this time, the above 4
The two pivot parts 11 to 14 are respectively disposed at the tops of the parallelogram and are pivotable.
Furthermore, since the base end (pivot part 16) of the auxiliary support arm 4 is restricted by the guide device 6 so that it can move only in the vertical direction, a certain height can be maintained as the door face body 1 moves upward. Up to this point, the angle between the main support arm 3 and the door face piece 1 gradually becomes smaller (for example, when the main support arm 3 is at an angle of about 40° to 60° with respect to the ground surface, the angle between the main support arm 3 and the door face piece 1 becomes smaller). The angle formed by this becomes the minimum (approximately 60°), and the locus of movement of the lower end 1a of the door face 1 begins to retreat inward (toward the support column). In this way, when the door face body 1 rotates, if the forward protrusion width of the door face body 1 is small (in this embodiment, it does not protrude outward from the front surface of the door face body 1 in the closed state), the door face body 1 in the closed state It becomes possible to install the gate close to the doorway structure (block wall, gatepost, etc.) Y, and there is no large gap between the inner edge Ya of the doorway structure Y and the side edge 1b of the door face piece 1. (Therefore, there is no need to fill the gap.) Furthermore, as the upward tilt angle of the main support arm 3 with respect to the ground surface F becomes larger than a certain angle (for example, 60°), the angle between the main support arm 3 and the door face 1 gradually increases, and the main support When the arm 3 is raised to the vertical position, the angle between the main support arm 3 and the door face 1 returns to 90°. When the main support arm 3 is in the vertical position,
The door face 1 is maintained in a horizontal position at the height of the tip 3a of the main support arm 3, and the lower part of the door face 1 is left wide open. In addition, when the main support arm 3 is in the vertical position, the elevating body 8 can only move in the vertical direction. When rotating the main support arm 3 downward (lower the lower end 1a side), it can be operated relatively easily, but it is possible to rotate only the main support arm 3 downward without pulling down the auxiliary support arm 4. Even if an attempt is made to pivot, the action (moment) of pushing the elevating body 8 downward against the support device 7 is reduced, and the main support arm 3 is prevented from inadvertently pivoting downward (there is a locking effect). .

In this first embodiment, each dimension (symbols H, L, W, T, etc.) in FIG.
The four pivot joints 11 to 14, which mutually pivotally connect the connecting rod 5, are set so as to be located at the tops of the rectangle when the main support arm 3 is in the horizontal position. Dimensions and the four pivot parts 11~
The shape of the parallelogram formed by 14 can be changed. In that case, when the door face body rotates, a part of the door face body 1 may protrude outward by a slightly wider width than the position of the door face body 1 in the closed state. By adopting a configuration in which the auxiliary support arm 4 is positioned at each top of the parallelogram and the base end side of the auxiliary support arm 4 is movable only in the vertical direction, if this configuration is not adopted (for example, in FIGS. 6 and 7), The protrusion width can be made smaller than that of a flip-up type door.

In the second embodiment shown in FIG. 3, the flip-up door shown in FIG. 1 is used to open and close the entrance to the garage, and the pillars 2, 2 at the entrance of the garage are used.
The main support arm 3 and the auxiliary support arm 4 are projected forward from the front side of the support column 2, but in other embodiments, they are projected forward from the inner surface (surfaces facing each other) of the support column 2. It may be made to protrude.

In the third embodiment shown in FIG. 4, when the distal end 3a of the main support arm 3 and the distal end 4a of the auxiliary support arm 4 are pivotally connected to the door face body 1, the distal end 3a of the main support arm 3 and the distal end 4a of the auxiliary support arm 4 are attached without using a bracket. Pins 91 and 92 provided at the arm tips 4a are directly pivoted to the frame 18 of the door face 1. Note that the base end 4b of the auxiliary support arm 4 is also connected to the support column 2.
It is pivoted directly to the pin 93.

In the flip-up door of the fourth embodiment shown in FIG.
The support device 7 is installed so as to support the door face body 1, the main support arm 3, the auxiliary support arm 4, etc. from above, contrary to the case of the first embodiment. In addition, in the case shown in Fig. 5, the main support arm 3 is installed at the bottom and the auxiliary support arm 4 is located at the top, and furthermore, when the door face body 1 moves upward, the elevating body 8 moves downward. At the same time, the telescopic cylinder 71 of the support device 7 is adapted to extend downward. The usage and function of the flip-up type door shown in FIG. 5 are almost the same as those of the flip-up type door of the first embodiment.

(Effects of the Invention) In the flip-up door of the present invention, the four pivot points 11, 12, 13, 14 that pivotally connect the door panel 1, main support arm 3, auxiliary support arm 4, and connecting rod 5 to one another are located at the apexes of a parallelogram, and further the base end 4b of the auxiliary support arm 4 can only move in the vertical direction. This has the effect of reducing the protruding width of the door panel 1 (the width that protrudes outward from the position of the door panel 1 in the closed state) when the door panel 1 is opened or closed, and allowing the door panel 1 to be installed closer to an entrance structure.
