Description

[Detailed description of the invention] This invention relates to an automatic lock for a gate installed between a gatepost and a gate.The purpose of this invention is to determine whether the gate opens to the right or the left. Another object of the present invention is to provide an automatic lock for a gate that can be used regardless of whether it opens inward or outward.

The structure of the present invention will be described below with reference to illustrated embodiments.

Figure 1 shows the external appearance of a gate 1 using the automatic lock of the present invention. As shown in the figure, one end of the gate 1 is rotatably supported on one gate post 2, A handle block 3 is attached to the free end side.

A rotatable latch bolt 4 is attached to the handle block 3, and the latch bolt 4 engages with a receiving block 6 attached to the other gate post 5.

FIG. 2 shows a mechanism for securing the handle block 3 and the receiving block 6, and the latch bolt 4 of the handle block 3 can be rotated as shown by the chain line A around the rotation axis 7. It is designed so that it can engage with the money receiver 8 of the money receiver block 6.

The receiver block 6 includes a receiver fixing fitting 9 attached to the gatepost 5 as shown in FIG. It is constructed with a force bar of 10.

The receiver fixture 9 is provided with a long hole 11 along the height direction, and the long hole 11 has two fixing bolts} 12.
13 can be installed.

However, when attaching the receiver fixing metal fitting 9 to the gatepost 5,
Adjust the height of the receiver fixing bracket 9 in the direction shown by arrow C to match the height of the handle block 3 attached to the side of the gate 1, and then fix the fixing bolt} 12.13. be.

The receiver fixing bracket 9 has a pair of tapped holes 14 and 15 in the vertical direction.
are provided, and the mounting screws 1 inserted into the screw insertion holes 16 and 17 of the holder force bar 10 are inserted into the screw holes 14 and 15.
8 and 19 are screwed together so that the receiver force bar 10 can be fixed to the receiver fixing fitting 9.

The receiver 8 is provided with a screw hole 20, and the receiver force bar 1
A pair of screw insertion holes 21 and 22 are provided in the left-right direction at a height corresponding to the tapped hole 20 of No. 0.

The mounting screw 23 is inserted into either one of the screw insertion holes 21 or 22 and screwed into the screw hole 20 of the receiver 8, thereby making it possible to adjust the position of the receiver 8 in the left and right direction. This is what I did.

Next, FIGS. 4a-d show four ways of opening and closing the gate 1, and FIGS. 5a-d show how to move the receiving block 6 to the gateposts 2 and 5 when each of the above-mentioned opening and closing methods is used. This shows how to install it on the house side.

First, Fig. 4a shows the right-hand inward opening method. In this case, the mounting screw 23 is screwed into the tapped hole 20 of the receiver 8 through the screw insertion hole 21, and as shown in Fig. 5a. The receiver 8 is made to protrude to the left side of the gatepost 5, and the inclined surface 24 of the receiver 8 is oriented toward the house.

Fig. 4b shows the left-inward opening method; in this case, the receiving block 6 used in the right-inward opening method is turned upside down and received on the right side of the gatepost 2 as shown in Fig. 5b. The metal 8 is made to protrude, and the inclined surface 24 of the metal receiver 8 is oriented toward the house.

Next, FIG. 4C shows the left outward opening method. In this case, the mounting screw 23 is screwed into the tapped hole 20 of the receiver 8 through the screw insertion hole 22, as shown in FIG. 5C. The receiver 8 is made to protrude to the right side of the gatepost 2, and the inclined surface 25 of the receiver 8 is oriented toward the outside of the house.

Furthermore, FIG. 4d shows a right-side opening method. In this case, the receiver block 6 used in the left-side opening method is turned upside down and placed on the left side of the gatepost 5 as shown in FIG. 5d. The receiver 8 is provided in a protruding manner, and the inclined surface 25 of the receiver 8 is oriented toward the outside of the house.

In this way, when the opening/closing method of the gate 1 is an inward-opening method, the sloped surface 24 of the receiver 8 is oriented toward the house, and on the other hand, when the opening and closing method of the gate 1 is an outward-opening method, the inclined surface 25 of the receiver 8 is oriented toward the outside of the house. By configuring it in this way, the inclined surface 4a provided on the latch bolt 4 of the handle block 3 is aligned with the receiver 8.
The latch bolt 4 rotates along the inclined surface 24 or 25 of the receiver 8 and returns to the horizontal direction, so that when the gate 1 is closed, the latch bolt 4 rotates along the inclined surface 24 or 25 of the receiver 8 and then returns to the horizontal direction. The gold block 6 and handle block 3 are automatically latched.

FIG. 6 shows the structure of the handle block 3. On the inner surface of the back body 26, there is a space 27 for attaching the latch bolt 4 to a pair of upper and lower support walls 28a, 28.
A recessed portion is provided at the lower right of the upper support wall 28a and at the upper left of the lower support wall 28b so that the latch bolt 4 can be rotated counterclockwise from a horizontal position. 28 C and 28 d are present.

Is latch bolt 4 a latch bolt for opening inward? 4, and a latch bolt 4 for outward opening, and either one of the latch bolts 4 or 42 is selectively used.

The latch bolt 4 is rotatably supported by a rotation shaft 7 passing through a back plate 29 and a front body 30.

When the front plate 33 to which the slide fitting 31 is fixed via the mounting screws 32 is lifted upward and the slide fitting 31 is slid upward along the front body 30, the drive protrusion 34 of the slide fitting 31 rotates. The arm 35 of the shaft 7 is rotated, whereby the latch bolt 4 is rotated and removed from the receiver 8.

In addition, when the front plate 33 is not lifted in this way, the latch bolt 4 is urged by the return spring 36 and is constantly returned to the horizontal position, which causes the latch bolt 4 and the receiver 8 to It is designed so that the two can be mutually guaranteed.

Note that 37 is a mounting screw for fixing the back body 26 to the front body 30.

The present invention is constructed as described above, and has a pair of sloped surfaces that are substantially parallel to each other on the front side of one longitudinal end of the prismatic receiver and the back side of the other end in the longitudinal direction. A receiver support is provided in which the receiver is slidably inserted in the longitudinal direction, and the receiver is attached to the receiver support at a position where one of the pair of sloped surfaces of the receiver protrudes from the receiver support. A receiver fixing means for fixing is provided, and one of the latch bolt support and the receiver support having a latch bolt that rotationally engages with the receiver is attached to the free end side of the gate, and the other is attached to the gate post. Therefore, depending on whether the gate opens and closes inward to the right, inward to the left, outward to the right, or outward to the left, the receiver is provided at both longitudinal ends of the receiver. By selectively protruding one of the inclined surfaces from the receiver support and selecting the vertical mounting direction of the receiver support,
This has the advantage that the same money receiving support can be used in common for four different gate opening/closing methods.
