Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an interlocking device for a gate handle and a drop lock.

[Conventional technology]

The gate is equipped with a handle for opening and closing, and a lock for securing the gate when it is closed.
Conventionally, the handle and the lock have been provided completely separately, with no interaction between them in particular.

[Problems to be solved]

In the case of conventional gates such as those mentioned above, from the state where the gate is locked with a drop lock and the position of the gate is fixed,
In order to open a gate, it is necessary to perform two separate operations: pulling up the lever of the lock to unlock it, and removing the handle from a latch or other means of latching, which is cumbersome. Moreover, since the lock was located at a low position, the lock had to be operated by bending down each time.
The present invention aims to solve these conventional problems.

[Means for solving problems]

The present invention, as a solution to the above problems, connects a rack made of a separate member to the top of the lock lever of a drop lock housed in a vertical stile, and operates in conjunction with the rotation of the gate handle. A gear mechanism for moving the lock up and down through the rack is provided in easy engagement with each other, the gear mechanism and the rack are housed in a case to form a unit, the unit case is installed inside the vertical stile of the gate, and the The gear mechanism constituting the unit amplifies and easily transmits the rotation of the handle, providing interlocking operation of the gate handle and drop lock.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially sectional front view showing an embodiment of the present invention, in which a gate 1 is assembled into left and right vertical frames 2, 3 and upper and lower frames 4, 5, and a plurality of decorative panels 6 are attached inside. A lock rod 7 for fixing the position when the gate 1 is closed is housed inside one vertical stile 2 to form a drop lock.

The lock lever 7 has an interlocking device 11 at its upper end that includes a rack 8, a gear mechanism 9, and a handle 10.
is installed. Of these, the rack 8 consists of a substantially trapezoidal mounting portion 12 and a rack portion 13.
The upper end of the locking rod 7 is connected and fixed to the lower end of the rack part 13, and is configured to move up and down integrally as will be described later.

As shown in FIGS. 2 and 3, the gear mechanism 9 has a plurality of gears housed in a case 14 fixedly installed inside the vertical stile 2. The gear mechanism 9 includes a first large gear 15 coaxial with the handle 10; It consists of a gear 16 and a second large gear 18 coaxially equipped with a small gear 17. The first large gear 15 meshes with the idle gear 16, and the idle gear 1
6 meshes with a small gear 17, and a second large gear 18 meshes with a rack portion 13 of the rack 8. Further, openings 19 and 20 are formed in the case 14 at upper and lower corresponding positions, and the rack part 13 of the rack 8 allows the inside of the case 14 to be opened through these openings 19 and 20 as the lock lever 7 moves up and down. It is now possible to move.

That is, a part of the rack 8 and the gear mechanism 9 are housed in the case 14 to form a unit,
This unit case 14 is attached to the vertical stile 2 of the gate.

The vertical frames 2, 3, upper and lower frames 4, 5, decorative panel 6, etc. in the figure are mainly made of extruded materials such as aluminum. Further, in the figure, 21 is a guide member, 22 is a drop tray, 23 is a gatepost, and 24 is a partner gate, which is equipped with a latch 25 for receiving the handle 10, and the handle 10 and the latch 25 form an inner latch. .

Next, the operation in this embodiment will be explained. lock rod 7
When the door 1 is to be raised and pulled out from the drop tray 22 and the gate 1 can be rotated to open and close, the handle 10 held by the latch 25 is rotated in the direction of arrow A in the figure. Then, the first large gear 15 coaxial with the handle 10 also rotates in the same direction, causing the idle gear 16 to rotate in the opposite direction as shown by the arrow in the figure. The small gear 17 that meshes with the idle gear 16 rotates in the opposite direction to the idle gear 16, that is, in the same direction as the handle 10 and the first large gear 15. Then this small gear 1
A second large gear 18 coaxial with 7 also rotates in the direction of arrow A, and the rack portion 13 meshing with this large gear 18 rotates in the direction of arrow A.
is pushed upward, and the lock rod 7 is pulled upward from within the drop tray 22 as the rack 8 rises. After the operation is completed, the handle 10 maintains its stopped position due to the balance between the frictional force caused by the meshing of the gears 15, 16, 17, 18 and the rack portion 13, and the weight of the locking lever 7 and rack 8. That is, the force applied to the handle 10 is applied to the two large gears 15 and 18.
It is amplified by the small gear 17 linked to these and is used to pull up the lock rod 7 without any force.

Of course, when the lock lever 7 is lowered, the operation is the opposite to the above, so a description thereof will be omitted. In addition, easy 8
The shape of the gear mechanism 11 and the structure of the gear mechanism 11 are not limited to the illustrated example, and various shapes can be adopted.

[Effect of idea]

As explained above, in this invention, the rack to which the locking rod is attached is moved up and down by a gear mechanism linked to the handle, so by operating the handle of the inner latch, etc., you can drop the lock without bending down. can be operated at the same time, and since the gear mechanism is built into the case together with the rack and has a unit structure, multiple gears can be easily incorporated, and the rotation of the handle can be amplified and easily transmitted. , it is possible to achieve the effect as an amplification unit.
