Description

[Detailed description of the invention] This invention relates to a double-barrel swinging gate.

For gates with large frontage, double-barreled gates are used, in which one side is pivoted to a gatepost, the other side is rotatably connected to the other side by a hinge. There is. If the gate is made of metal, especially cast metal, it is heavy, so wheels are attached to the lower part of the other gate and the wheels are grounded to support the load of the gate. However, in the conventional double-opening gate, the two gates connected to the hinge are only capable of relative rotational movement around the vertical axis, and are fixed to each other in the vertical direction. On the other hand, the ground in the rotation area when the gate opens and closes is usually sloped upward toward the inside of the site, taking drainage, sweeping, etc. into consideration. Therefore, when opening and closing the conventional double-barrel gate, the wheels come into pressure contact with the sloping ground surface, increasing running resistance, which has the disadvantage that opening and closing operations may become difficult. In order to ensure that the wheels are firmly on the ground and support the gate load in the closed position of the gate, and that the opening/closing operation is not excessively heavy, the wheel mounting position must be selected at the gate installation site.
The wheels are pre-mounted in position, since the selection and wheel mounting operations are extremely tedious. Therefore, it was inevitable that the slope of the ground at the gate entrance would make it difficult to open and close the gate.

The purpose of this invention is to provide a double-opening gate that can be opened and closed easily and smoothly regardless of whether or not the ground at the gate entrance is sloped.

Next, one embodiment of this invention will be described based on the drawings.

G ₁ is a double-barrel swinging gate based on this idea,
One side of the gate 3 is rotatably attached to the gate post 1 with a hinge 2 on one side, and on the other side of the other gate 4, at least two upper and lower hinges 5 can be rotated. A swivel wheel 6 is protruded from the lower end of the other gate 4 and is connected to the ground at least on the hinge 5 side.
In this invention, the hinge 5 holds the door end side gate 4 movably up and down with respect to the gate post side gate 3.

An example of the structure of the hinge 5 that connects the gate 4 to the gate 3 in a rotatable and vertically movable manner will be described with reference to FIGS. 2 and 3. Hinge 5 has two leaves
It consists of L ₁ , L ₂ and pin P. One leaf L ₁
It integrally has a plate part 7 fixed to the gate and a knuckle part 8 provided on one side of the plate part. The knuckle portion 8 is provided in the lower half of the plate portion 7.
The other leaf _L2 has the same shape as the one leaf _L1 , and is used by arranging it in a direction rotated by 180 degrees with respect to the latter leaf. Therefore, the parts corresponding to the respective constituent parts of one leaf _L1 are indicated by adding e to the former symbol. Then, by aligning the knuckle portion 8 of one leaf _L1 and the knuckle portion 8e of the other leaf _L2 in a straight line, and inserting the pin P into these knuckle portions 8, 8e from above, the hinge 5 is It is configured.

The head 9 at the upper end of the pin P is connected to the upper knuckle portion 8e.
is held by one leaf _L2 . Also, the length of the shaft of this pin P is the length of the above two leaves.
The length is longer than the total length of the knuckle portions 8, 8e of L ₁ and L ₂ , and a stopper 10 made of a split pin or the like is protruded from the lower end. Therefore, the other leaf _L2 protrudes downward by an amount l from the leaf _L1 of _the pin P in the state shown in FIG.
The two leaves L ₁ and L ₂ can rotate relative to each other around the pin P.

The hinge 5 has the two leaves L ₁ and _{L 2} at the same height as shown in FIG. The leaf L ₂ is fixedly attached to one side end of the other gate 4 by a plurality of screws 11 at the plate portions 7 and 7e, respectively, and connects the two gates 3 and 4.

In the illustrated example, the plate portion 7 is preferably bent into an L-shape in plan, and a protrusion 12 is provided on the back surface of the front portion 7a, and the protrusion is inserted into a groove provided on the other side of the gate 3. The screws 1 are fitted together, and the back surfaces of the front surface portion 7a and side surface portion 7b are brought into contact with the front surface and the other end surface of the other side of the gate 3, and the screw 1 is inserted from the side surface portion 7b.
By screwing L 1 into the gate 3, the connection of the leaf L ₁ to the gate 3 is made solid. The connection of the other leaf _L2 to the gate 4 is also the same.

Note that the hinge 5 shown in the figure is for ease of manufacturing.
The left and right leaves L ₁ and L ₂ have the same shape, and therefore the knuckle parts 8 and 8e are half the length of the upper and lower parts of the plate parts 7 and 7e, but the hinges used in this invention are the same as those mentioned above. The shapes of the plate part and the knuckle part are not limited to those shown in FIG. in short,
It is sufficient that one leaf is supported so as to be movable up and down and rotatable relative to the other leaf using a pin longer than the length of the knuckle portions of the two leaves.

Reference numerals 14 and 14e are drop bars that are attached to the lower ends of the free end sides of each of the gates 3 and 4 so as to be movable up and down.

Since the structure is as described above, when the gate is closed, if the ground 16 below the gate is horizontal, each of the hinges 5 is
As shown in FIG. ₂ , the leaf L2 fixed to the other gate 4 is supported or in contact with the leaf _L1 fixed to the one gate 3 at the knuckle parts 8, 8e. The left and right gates 3 and 4
are at equal height to the ground. Moreover, the adjustable wheel 6 also supports the load of the front door side gate 4 in an auxiliary manner.
When the gate entrance ground is horizontal within the rotation range of this double-opening gate, the reaction force (running resistance) received from the ground by the swivel vehicle 6 does not change at any position during the movement of the gate. The gate can be opened and closed smoothly and easily.

On the other hand, when the gate entrance ground 16 slopes upward toward the inside of the site, as shown in FIG. 4, the grounding point of the movable vehicle 6 becomes gradually higher when opening the gate, When one gate 3 becomes perpendicular to the closed position shown in FIG. 1 as shown in FIG. 4, it reaches its highest level, and thereafter gradually decreases. Therefore, the leaf L ₂ of the hinge 5 on the other gate 4 side moves up and down with respect to the leaf L ₁ of the gate post side gate 3 via the pin P, depending on the height of the grounding point of the adjustable wheel 6. move. Therefore, if the protruding length l of the pin P is made longer than the head difference h between the highest grounding point and the lowest grounding point of the movable wheel 6, when the gate is opened or closed, the other gate 4
freely moves up and down according to the inclination of the gate entrance ground 16 (the amount of movement is equal to the head), and the movable wheel 6 does not apply a force greater than the load of the other gate 4 to the ground. In other words, even if the ground at the gate entrance is sloped, excessive running resistance will not be applied to the freewheeling vehicle.
The gate can be opened and closed smoothly and easily.

Further, since the swivel wheel 6 is provided below the hinge 5 side of the gate 4 which moves up and down, the vertical movement of the swivel wheel due to the slope or unevenness of the ground is directly caused by the hinge 5 side.
Since the leaf _L2 is moved in a direction parallel to the axis of the pin P (that is, in the vertical direction), the gate can smoothly move up and down along the inclined surface.
When the gate 4 moves up and down, the load of the gate is applied only to the swivel wheel 6, and the swivel wheel disperses this load onto the ground.
This prevents excessive load from being applied to the hinge 5 or the hinge 2 on the gatepost side, causing premature deterioration of these hinges.

In addition, when the slope of the ground at the gate entrance is small, even if the two gates 3 and 4 are opened and closed in a straight line, the lower end of the other gate 4 will hit the ground and prevent the gate from rotating. Never.

In addition, in FIG. 1, _G2 is a side gate, which is pivoted to the gatepost 1e by a normal hinge 2e similar to the hinge 2 described above.

As mentioned above, in the double-swing gate according to this invention, firstly, the front side gate can be moved up and down according to the slope of the ground, so even if the ground is sloped, there is no need for excessive movement on the freewheeling vehicle. Since no running resistance is applied, the gate can be opened and closed easily and smoothly.
Second, since a swivel wheel that supports the gate auxiliary is installed below the hinge side of the gate on the front side of the gate, changes in the height of the sloping ground can be effectively applied to the hinge directly above it via the swivel wheel. This allows the gate to move up and down smoothly,
In addition, the load caused by the vertical movement of the gate is distributed to the ground by the swivel wheel installed directly below the hinge, so the hinge connecting the two gates and the hinge on the gate post side will not deteriorate.
