Description

[Detailed Description of the Invention] This invention relates to a hinge device for a gate, and more specifically, to a hinge device for a gate that allows the support position of a swinging gate with respect to a gate post to be arbitrarily adjusted.

Generally, it is impossible to adjust the amount of protrusion of the armrest on the gatepost side of an existing swinging gate (elbow hardware or pot hardware) from the gatepost, and especially for armrests buried in concrete gateposts, it is necessary to replace them. It is extremely difficult. Since the existing armrests on the gateposts are made of steel and have excellent durability and strength, it is desirable that the existing armrests on the gatepost side can be used as they are when replacing the gate with a new one. However, the dimensions of new replacement gates are determined by standards, so adjustments will be required when installing them.

Thus, this invention provides a gate hinge device that can support a replacement gate using the existing armrest hardware of the gatepost, and also allows for easy position adjustment. The purpose is to

An embodiment of the next invention will be described based on the drawings.

In Figure 1, P is a gatepost, 1 is an existing pot hardware protruding from the gatepost, and there is a pin receiving hole 2 at the tip.
has. Further, G is a replacement opening gate, and 3 is a pot hardware fixed to the gate, which has a pin receiving hole 4 at one end.

Reference numeral 5 denotes an armrest, which is one of the important components of this invention, which protrudes downward from one side of the horizontally extending pin holder 6 and rotates into the pin receiving hole 2 of the pot hardware 1 of the gate post. The first part can be inserted freely.
A pin 7 is fixedly provided, and a second pin 8 is fixed to the other side of the pin holder 6 so as to protrude upward and can be rotatably inserted into the pin receiving hole 4 of the gate G. The first pin 7 has a length such that its lower end protrudes below the pot hardware 1 when it is inserted into the pin receiving hole of the pot hardware 1, and the tip thereof is threaded.

Reference numerals 9 and 10 denote a spring washer and a nut, and the spring washer 9 is fitted to the lower end of the first pin 7 which is inserted into the pin receiving hole 2 of the pot hardware 1 and projects downward from the pot hardware 1. By loosely tightening, the elbow hardware 5 is rotated on the circumference around the first pin 7 until it forms a desired angle with respect to the gatepost, and then by strongly tightening the nut 10, the pin holder 6 is rotated. The gate can be fixed so that it does not rotate due to external force applied when opening and closing the gate. That is, the male thread of the first pin 7 and the nut 10
constitutes an example of a fastening means for fastening the elbow hardware 5 to the vase hardware 1 at a position where the pin holder 6 has a predetermined angle with respect to the gatepost P and preventing rotation thereof.

However, the frictional force caused by the tightening of the nut 10 alone cannot completely prevent the pin holder from being rotated by the strong force applied to the pin holder 6 through the vase hardware 3 when opening and closing the gate. There is a risk.

Numerals 11 and 16 are locking members provided to supplement the rotation-preventing force generated by tightening the nut 10. The first locking member 11 is formed into an annular shape having a hole 12 in the center through which the first pin 7 is inserted, and at least one protrusion 13 is provided on the upper surface thereof. When the first pin 7 is inserted into the hole 12 and the first locking member 11 is pressed against the lower surface of the pin holder 6, the protrusion 13 fits into the groove 14 provided in the pin holder. 1 locking member 11 is pin holder 6
cannot be rotated against. In addition, the first locking member 11
An uneven surface 15 in which radially extending grooves and peaks are alternately arranged is formed on the lower surface of the holder.

The second locking member 16 is formed by connecting a saddle-shaped attachment part 18 to the side surface of a cylindrical part 17, and the cylindrical part 17 extends from the lower surface to near the upper end, into which the pot part 1a of the pot hardware 1 can be inserted. A hole 2 is provided at the center of the upper end of the cylindrical portion, which communicates with the hole 19 and into which the first pin 7 can be inserted. An uneven surface 21 similar to the uneven surface 15 is formed.

The second locking member 16 is placed over the pot hardware 1 from above, and the second locking member 16 is inserted into the hole 19 of the cylindrical portion 17.
a, the arm portion 1b is fitted into the mounting portion 18, and the hole 2 is
0 is in communication with the pin receiving hole 2 of the pot hardware 1, and is fixed by screwing the screw 22 from the mounting portion 18 toward the pot hardware 1. Since the attachment part 18 is fitted into the arm part 1b of the vase hardware, the second
The locking member 16 cannot rotate relative to the pot hardware 1.

The first and second locking members 11 and 16 pass the first pin 7 inserted through the hole 12 of the first locking member 11 into the hole 20 of the second locking member 16 and the pin receiving hole 2 of the pot hardware 1. A washer 9 and a nut 10 are attached to the end projecting downward from the vase hardware 1, and the uneven surfaces 15 and 21 are engaged with each other.

With the above configuration, the second locking member 16 is first attached to the pot hardware 1, then the elbow hardware 5 with the first locking member 11 attached is temporarily fixed with the first pin 7 and nut 10, and the pot hardware 3 is attached to the second locking member 16. Support with 2 pins 8 and install the gate. If the position of the door end relative to other gate pillars in the case of a single-swinging gate, or the positional relationship between the door ends of both gates in the case of a double-swinging gate is not appropriate due to the width dimension of the gate, loosen the nut 10. , the position can be adjusted by rotating the pin holder 6 around the first pin 7,
After adjustment, tighten nut 10 again, and the first
Due to the engagement of the uneven surfaces of the second locking members 11 and 16,
Unnecessary rotation of the pin holder is completely prevented, and the installation condition of the gate will not be messed up.

As described above, according to this invention, the replacement gate can be installed in an appropriate state or the installation position can be easily adjusted by using the existing pot hardware 1 of the gate post as is. Since radial uneven surfaces are formed on the facing surfaces of the first locking member and the second locking member, the angle can be easily set to any desired angle, and the angle will change due to loosening after tightening. It stays in place.
