Description

Detailed Description of the Invention The invention of this application is to operate a locking rod connected to the rotary handle on the inner seat by operating a rotary handle provided on an outer seat of a gate or the like. It is related to a gate lock for tightening and locking.

Special feature 1: The locking rod is configured to slide via a speed increasing gear mechanism by operating a rotating handle;
In addition, a gate lock is provided with a lock portion that can be engaged with a main gear interposed between the speed increasing gear mechanism and the rotating handle.

Conventionally, gate locks used to lock gates, etc., have an outer seat 21 of a gate 1, a rotating handle 3 in the shape of a hanging ring, and an inner seat 4t, as shown in FIG. This is provided with a hook-shaped locking rod 6 that can be rotated once parallel to the gate 1, and the locking rod 6 is inserted through the gate 11 through an operating rod (not shown). It is connected to the rotary handle 3, and rotates in accordance with the rotation operation of the rotary handle 3, so that a locking member such as a hook 8, etc., is engaged with the opposing gate γ, etc. It had been.

However, since gate locks need to be strong due to their security requirements, each part of the gate lock is designed to ensure sufficient strength, and in particular, the locking function is The locking rod 6, which is the main part of the locking rod, is generally made of a metal such as iron, which is strong, and therefore has a weight of one weight.

Therefore, when rotating the heavy locking rod 6, a considerable amount of rotational force is required to operate the handle 31, and the lateral extension of the locking rod 6 is Due to its shape, the center of gravity is eccentric and the rotation is not smooth, resulting in extremely poor operability, and the locking rod 6 has a weight moment of 1 when not merging with the mating hook 8. Since it has the property of rotating to the vertical position, in this state, the rotating bundle 3 connected to it stops in an eccentric state,
There was also the inconvenience of deteriorating aesthetics.

In addition, in this case (operation from inside the gate), the locking part 6 is manually rotated, but at the time of this operation, the finger may be caught between the locking part 6 and the hook 8 on the other side. There were also risks.

[This is a means of locking the gate lock based on the above-mentioned prior art (based on the above-mentioned conventional technology). Measures such as locking the lock were taken, but 1. This means that when the lock is not on, such as during the daytime, the above-mentioned lock is used.

Moreover, it not only has the disadvantage of requiring extremely complicated management such as the need to remove the small lock, but also has the disadvantage that it is difficult to unlock from the outside of the gate once it is locked, so it is difficult to operate it when going out. sex was inconvenient.

The purpose of the invention of this application is to solve the problem E of the gate lock based on the above-mentioned prior art 1, to make the lock body a sliding lock part, and to increase the number of main gears connected to one rotation bundle. By engaging the rack part of the locking part through a speed gear and converting the rotation of the rotating bundle into the sliding force of the locking part1, the disadvantages in operating the locking part based on the above-mentioned prior art can be overcome. In addition, the above-mentioned main gear can be locked with a trowel in the locking portion 1. This provides an excellent gate lock that eliminates the disadvantages of conventional lock operations. This is what I am trying to do.

The structure of the invention of this application in accordance with the above object 1 is that when a gate is closed and the gate is locked, after the gate is closed by gripping a rotary bundle provided with an outer seat. 1
When the rotary bundle is rotated, a locking portion provided with an inner seat in conjunction with the rotating bundle slides and extends once while increasing the stroke speed, and is inserted and locked against the mating locking mechanism. When the lock is in the locked state, and when the lock is to be unlocked, the rotating bundle must be rotated in the opposite direction (1), and the locking section can be pulled out from the locking mechanism on the other side to unlock the lock. Therefore, the above-mentioned locking and unlocking operations can also be performed by sliding the locking part from the direction of the inner seat. The lock cam should be locked so that the lock cam can be locked against the main gear 3 connected to the rotating bundle 1 by rotating the knob F or flip-flop using the key 1. The main points are as follows.

The frame body 22 is fitted into the frame body 22 so as to be rotatable, and square holes 50, 50' are formed as conical holes on both end faces of the frame body 22, and the tip 1 as shown in FIG. The lock 521 having the square hole engaging portion 51 can be viewed from the inside of the gate by engaging the square hole 50t, and from the outside of the gate by the lock 521 which is drilled downward through the rotary seat 1γf of the outside collapse 10. The square hole 50' is engaged with the square hole 50' through the insertion hole 53 so that the locking operation can be performed.

Reference numeral 54 54' denotes a locking body drilled at a predetermined angle from the circumferential side of the lock portion 49.

Each side of the inner wall 11 is provided with a small protrusion 55, 55', and correspondingly, the upper wall 111 of the inner wall 111 is provided with a small protrusion 55, 55'.
- Concave portion 56°56' that can be engaged with the protrusions 55, 55'
56"56"' is provided in the positional relationship shown in FIG. The lock portion 49 is bent so as to be able to flip-flop in conjunction with the urging action of a spring 58 interposed therein.

In the state shown in FIG. 10a, 55 of the small protrusions of the lock portion 49 are 56 of the concave portions of the inward collapse 11.
' and 55' engage with 56'', while in the state shown in FIG. 10b, only 55' engages with 56''.

Further, 59 is a triangular stopper protruding from the surface of the indentation 11, and is adapted to engage with the locking body 54 of the trowel locking portion 49, as shown in FIG. 10b.

Now, to explain the positional relationship between the lock portion 49 and the main gear 25, the lock portion 49 is connected to the central cylindrical portion 6.
0 is inserted through the semicircular slit 611 of the main gear 25, and regardless of the presence of the lock portion 49, the slit 1 is inserted so that the main gear can rotate. A space is provided within the notch 62 carved on the side of the folding part 11 so that the locking bodies 54, 54' of the locking part 49 can rotate.

Furthermore, two protrusions 6363' are provided within the notch 62 and are branched from each other at a predetermined angle.
10b. In the state shown in FIG.
In the state shown in Figure 0a, the protrusions 63 63' are the locking bodies 54 5
4'F is not restricted and the main gear 25 is rotated by 1 so that it can rotate freely.

Therefore, the relationship between the projections 63 and 63' and the stopper 59 is such that the stopper 59 and the projection 6363' are in the tenth position.
a The vertical dimension 1 in Figure 10b does not engage with each other, that is, the height dimension from the inner collapse 11 of the stopper 59 and the inner collapse of the protrusions 63 and 63' as shown in Figure 9. The passage gap amount H from 1 to 5 has a relationship of h<H, and on the other hand, the stopper 59 is
, 54' are bent once so that they can be engaged.

In addition, the protrusion 63 63', the locking body 5454' and the recess 5
6, 56', 56", and 56"' are provided in pairs, one symmetrically, in the so-called right-hand and left-hand designs.
This trowel has been carefully designed so that it can be used with the same parts.

In the above configuration 1, when performing the normal gate opening/closing operation, the rotation lock of the main gear 25 is released, that is, the lock portion 49 is operated by inserting the key 52 and the 1
As shown in Fig. 08, the slight protrusion 55 is inserted into the concave portion 5 of the inward collapse 11.
6///, this, also, the other small protrusion 55' is connected to the other concave part 56.
``F'' is brought into the engaged state so that the rotation of the main floor car 25 is not restricted.

Therefore, when the gate is locked and you are trying to close it as shown in Figure 3, stand up the rotating band 18 on the gate 1 side and rotate it approximately 180 degrees to the right, and this and the operating stick 28 will be connected. The main gear connected via the main gear rotates in the direction of
Driven gear 29. The driving gears 35 are also rotated once in the direction A with the engagement gear ratio 1, and the locking rod 38 is rotated through the engagement of the rack portions 43 on both sides of the driving gears 35.
This is done so that the door can be opened by sliding the locking mechanism 45 on the other side to disengage it.

The amount of rotation of the rotating bundle 18 is 18o0, but as described above, the necessary stroke of the locking rod 38 can be obtained from the speed increasing gear mechanism 1.

In addition, in the state shown in FIG. 10a, when the main gear 25 rotates, 1
The protrusion 6363' is the locking body 54 of the lock portion 49.
, 54' and a stopper 5 provided with 111 inward collapses.
91 is not restricted, therefore, there is no effect on single-tablet operation.

Next, when the gate is transferred from the closed state to the open state, when the rotating bundle is rotated approximately 180 degrees to the left, each gear rotates in the opposite direction to that described above, that is, in the direction B and E. The engaged locking rod 38 moves out in the direction h in a manner opposite to the above process and separates from the mating locking mechanism 45, thereby releasing the gate.

Note that the above-mentioned operation of the rotating bundle 18 is performed from the outside of the gate, but when the operation is performed from the inside of the gate,
If the locking rod 38 is directly slid using the operation pin 44, locking operations can be performed.

In this case, the rotary seat 1γ and the rotary handle 18 connected thereto are indirectly rotated once through the gears 25, 29, and 35, but the load in this case is It does not interfere with operation.

By the way, as mentioned above, the operation from the outside of the gate is performed from the rotating bundle IFh, but at this time, after the opening/closing operation is completed,
When the rotating bundle 18 that has been held in an upright position is released, the rotating bundle 18 rotates under its own weight. As described in the above-mentioned specification of Utility Model Application No. 53-022312, the engagement action is made such that the gate does not rotate in the direction of the gate f beyond the hanging position.

Next, when the gate is locked, when the gate is locked, the key 52 is engaged with the square hole 50 from the inside of the gate against the lock part 491, and From the outside of the gate, the square hole 50't is engaged through the key insertion hole 53 of the outer lock 10, and the lock part 49 is brought into the state shown in Figure 1'Ob, that is, in the clockwise rotation direction when viewed from the inside of the gate. Turn the key one turn to the position where the small protrusion 55 engages with the concave portion 5671 of the indentation 11, and then remove the key.

゛In this state 1, even if an attempt is made to rotate the main gear 25 in the inward direction from the rotating bundle 18f, the protrusion 63 of the main gear 25 will not engage the locking portion 6 of the lock portion 49.
Since the locking portion 63 is engaged with the stopper 591, the rotation in the inward direction is prevented, and the pushbutton is in the locked state.

Next, the key 521 is used to release the lock 49 from the key 521. As shown in FIG. By returning the portions 56", 56"' to the engaged position, the above-mentioned normal lock opening/closing operation can be performed.

It should be noted that this invention is not limited to the above-mentioned embodiment f, and it is possible to design various shapes of the one-rotation bundle or the shape of the key, and no key is used.

A single knob may be provided in the locking portion, and the combination of gears in the speed increasing gear mechanism may be other than the above-mentioned embodiment.For example, in the above-mentioned embodiment 1.

The driving gear 35 is omitted and the driven gear 29 is directly connected to the locking rod 38.
By engaging with the rack portion 43 of the rotary bundle 18, the direction of rotation of the rotary bundle 18 can be reversed, and it is possible to make the rotary bundle 18 in the opposite direction.

In addition, the application target is not limited to general gates, and can also be used for fence locks and the like.

According to the above-mentioned aspect 1, invention 1 of the present application, since the locking body is a sliding type locking rod, the locking rod can be made sturdy and heavy, compared to the conventional rotating type. It not only has the advantage of being extremely easy to operate because it can be operated with a small turning force compared to the one-turn type, but also has a smooth sliding action, but it also has the advantage of being extremely easy to operate. There is no danger of your fingers being pinched by the lock rod and the hook on the other side, and therefore,
It is possible to make a more robust plan than one made of iron, taking security into full consideration.

In addition, since the sliding drive of the locking rod is performed by a main gear and a clutch gear mechanism, the structure is simple, yet reliable and less prone to failure. Due to the small turning angle of the one-turn bundle, sufficient locking rod sliding stroke can be obtained.

Even if the locking rod is made longer depending on the conditions of various gates, etc., the locking function will not be impaired in any way.

Furthermore, by providing a flip-flop rotating locking portion that has an engaging portion that engages with the locking portion provided with the aforementioned main gear, it is possible to easily lock the lock using a key or the like. It is possible to lock the state and improve the security of the gate,
In addition, the operability is extremely superior compared to the conventional lock structure using a lock and a small lock, and depending on the design, the key can be inserted from inside or outside of the gate.

In addition, one lock part is connected to the main gear.

There is a recessed slit that faces the lock part q.
This makes it possible to reduce the wall thickness of the main gear and, as a result, to reduce its weight, resulting in less rotational force of the main gear and an excellent effect of extremely smooth operation.

In addition, the above slit is formed by one slit from the circumference of the main gear.
The force of breaking is reduced, and the lock is more durable against breakage.

Furthermore, the lock part is a lock part having an engaging part that engages with one locking part provided with the one main gear, and which rotates a flip-flop equipped with the one inner seat part. 1 From this, the 'lock part is fitted inside the main gear fζ,
The effect is that it does not take up much space.
