Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention is applied to external gates for buildings, particularly garage doors.

[Conventional technology]

A proposal to make the height of the door higher than the opening locus of a normal rotary elevator door for storage of high-roof vehicles, etc. has already been made in Japanese Patent Application No. 60-35131; The invention further discloses a separate embodiment that adds new improvements.

[Problems to be Solved by the Invention] When a rotating elevator door is closed, the horizontal distance between the center of gravity of a rotating part such as the door and the axis of rotation becomes long, and a strong gravitational moment is generated. For this reason, a biasing mechanism is provided to offset the gravitational moment of the rotating part when closing the door and during each step of the operation.
In reality, there are a wide variety of ways to store this biasing mechanism (spring, etc.), and it is difficult to select one, and it may be unsightly in appearance, and the safety of injury to the human body must also be taken into consideration. The present invention proposes a sophisticated spring mounting method and a new embodiment in a rotating elevator door for a high-roof vehicle.

[Means and Embodiments for Solving the Problems] The configuration of an embodiment of the shaft-lifting/rotating elevator warehouse according to the present invention will be described with reference to a drawing. An axis X, and two shaft fulcrums 41 and 42 arranged on the axis
, two support arms 21 and 22 whose one ends 21a and 22a are pivotally supported by the two pivot points 41 and 42, and which are rotatable in a plane intersecting the axis X; and the second support arm 21.・2
Between the open ends 21b and 22b of the second support arm 2,
Decorative board (door) 1 installed in a direction intersecting with 1 and 22, 2 pillars 31 and 32 that respectively support the 2 shaft supports 41 and 42 on the ground surface, the door 1, and the support arm. 2
Biasing members 61 and 6 that provide a moment in the anti-gravitational direction that counteracts the gravitational moment exhibited by rotating parts such as 1 and 22'.
2 and stoppers 51 and 52 that limit the rotation stroke of the second support arms 21 and 22 over a range of approximately 90° from approximately horizontal to approximately vertical directions, the second lid body 31a and 32a to the above two pillars 31 and 32
The two shaft supports 41 and 42 are fitted in and slidable along the longitudinal direction of the pillars 31 and 32, respectively, and the two shaft supports 41 and 42 are protruded from the upper parts of the lids 31a and 32a, and the biasing members 6
1 and 62 are the pillars 31 and 32 and the lids 31a and 3.
The ends 21a and 2a of the two support arms 21 and 22 are mainly loaded and engaged in the inner spaces of the support arms 31 and 32, respectively.
22a is slightly extended in the opposite direction to the open ends 21b and 22b, and the extended ends 21c and 22c are restrained to the ground surface with only slight horizontal arc-shaped swinging allowed. The structure is characterized by the following. Note that the direction of the unevenness of the horizontal arc-shaped swing does not matter; therefore, the arc shape includes a straight line.

Also, the short distance that is allowed to swing is the pivot point 41.4.
2 is the opening and closing of door 1 (therefore, the rotation of support arms 21 and 22)
This refers to the horizontal component of the locus drawn by the extending portion ends 21c and 22c when vertically moving up and down (depending on the extended length of the support arms 21 and 22).

). Furthermore, the second digit 2.1 used in this specification indicates the left and right sides of the support arm system, and although some are not shown, they are represented identically to those of other systems. .

[Effect]

Since the present invention has the above configuration, the support arms 21 and 22 are vertical when the door is opened (if the mounting angles of the support arms 21 and 22 with respect to the door 1 are oblique in the side view, they are vertical. ), the pivot point 41
・The lid bodies 31a and 32a that support the support columns 31 and 32
The door 1111 is at its maximum vertically elevated position, and is still slightly biased upward by biasing members 61 and 62 to prevent it from falling down by itself in the event of a gust of wind. At this time, the ends 21c and 22c of the extended portions extended at an obtuse angle to the support arms 21 and 22 (this is done in consideration of the fact that the extended portions do not come into contact with the lids 31a and 32a) are horizontally swingable. It is located near the most fulcrum points 41 and 42 of the locus.

When the door 1 begins to rotate in the closing direction from this state, the extension ends 21c and 22c begin to move along the horizontal swing locus in a direction away from the pivot points 41 and 42, and at the same time, the pivot points 41 and 42 are connected to the biasing member. 61/62 and was forced to fall. Continuing this state, the door finally reaches a closed state, and the shaft support 44
1 and 42 will receive the maximum upward force (of course, the extended portion ends 21c and 22c are furthest away from the pivot points 41 and 42 when the extended portion is horizontal). be.). Here, when rRl is rotated again in the door opening direction, since the extension portion ends 2lc and 22c are restricted to horizontal swing only, the pivot points 41 and 42 are moved vertically with the help of the biasing members 61 and 62. It begins to rise and reaches the open state mentioned at the beginning. The ground height of the door 1 when the door is closed is compared to the height of the opening 1 ft of a normal rotating elevator door in which the pivot points 41-42 do not rise vertically,
It is natural that the height is increased by the amount of the rise of the shaft supports 41-42, and it can be said that this is easily adapted to the storage of a high-roof vehicle. The biasing members 61-62 are attached to the pillars 31-32 and the lid 31.
a and 32a are completely waterproof, and the biasing members 61 and 62
It is unlikely that a person's fingers will get caught in it.

To restrict the horizontal swing of the extending portions 21c and 22C of the support arms 21-22, the lower portions of the columns 31 and 32 and the extending portion ends 21c
・This can be done by engaging 22c with the floating linking rods 71 and 7i.

[Other Examples]

Instead of the continuous rods 71 and 72, elongated holes matching the locus of the upper ends of the continuous rods 71 and 72 were provided integrally with the supports 31 and 32, and these elongated holes were planted at the ends of the extension parts 21c and 22c. The pin member may be restrained. Of course, we replaced it with a longer one and installed a pin member,
Reversed male-female engagement is also permitted (Figure 2).

The pivot points 41 and 42 are provided to protrude from the upper side surfaces of the lids 31a and 32a, and the lids 31 including the extending portion ends 21c and 22c are provided.
If included in a and 32a, the pivot points 41 and 42
The lower part can be configured as an IJ source with only the lids 31a and 32a and the pillars 31 and 32. In this case, the support arms 21 and 22 have pivot points 41 and 4 when viewed from the top view when the door is closed.
It will be extended in a crank shape through 2 (Figure 3)
.

As yet another embodiment, as shown in FIG.
&・Internal member 31b for inserting 32a into the inside of the pillars 31 and 32
・External material 3 that hides 32b and the outside of the pillars 31 and 32
It may be an integral member divided into 1c and 32c, or a connecting member formed by screwing together.

), the fitting between the pillars 31-32 and the lids 31a and 32a (fitting that maintains mutual rigidity mechanically) is performed by the pillars 31 and 32.
The inner members 31b and 32b can be used to do this as much as possible. The effects of such a configuration are as follows. (2) There is an advantage that high-strength, low-grade, and inexpensive members (such as iron) can be used for the internal materials 31b and 32b.

(2) The outer members 31c and 32c are part of the lids 31a to 32a, and protect the fitting portions of the inner members 31b and 32b and the pillars 31 and 32 from rainwater. (2) In a structure in which the external members 31C and 32c are in close sliding contact with each other, the sliding portions of the sliding portions come into the visual angle during operation, and an unfavorable appearance can be avoided. (2) Therefore, the outer members 31c and 32c are only meant as covers, and may be thin, low-rigid members.

Note that it is also possible to implement the configuration of the present invention in which the ground surface, the door, and the mounting surface are replaced within the technical scope of the present invention.

〔Effect of the invention〕

According to the present invention, it is possible to obtain the energy for reducing the gravity of a rotating part such as the door 1 and for raising the pivot points 41 and 42 using a single biasing member 61 and 62, and furthermore, Part 6
1 and 62 are reliably stored, the biasing members 61 and 62
It is possible to obtain a shaft-lifting/rotating elevator shed for a high-roof vehicle which can avoid wear and tear from rainwater and is highly safe for human bodies.
