Description

[Detailed description of the invention] Industrial application field This invention relates to a skylight lock for locking a skylight.

Prior Art Generally, skylights are always biased in the open direction by an opening means such as a gas damper, so they must be locked to a certain degree (the hook and lock catch are deeply engaged). If the lock is shallow, it will easily come off,
There is a risk that skylights may open unexpectedly due to vibrations and wind pressure during strong winds. This is even worse if the hook is worn out due to long-term use.

On the other hand, as a skylight lock for locking skylights,
A device described in Japanese Patent No. 58-47188 is disclosed. This invention extends the rear end of a rotatable hook provided on the skylight to an operating lever that is also rotatable,
Unlocking is accomplished by the rotation of the operation lever when it is pushed up, which causes the hook in contact with the lever to also rotate, and the hook to be released from the lock receiver provided on the ceiling.

Problems to be solved by this device If the device has the structure described above, the length from the rotation axis of the hook to the rear end of the hook is long, the length to the tip that hooks on the lock catch is short, and the operation lever is short. At the same time, even if the rear end of the hook is rotated greatly, the rotation of the tip will be reduced. Therefore, if the hook portion at the tip of the hook is made too large, even if the hook rotates, it will not be disengaged from the lock receiver, and the hook portion must be made smaller. In particular, with a skylight, the window glass is located above, which limits the amount of lift of the operating lever, which also makes it impossible to make the hooking portion at the tip of the hook larger.

The fact that the hook at the tip of the hook is small means that
This means that the engagement between the hook and the lock receiver becomes shallow, and the prior art does not meet the requirements for skylight locks described above.

Means for Solving the Problems In the skylight lock according to this invention, the hook consists of two integrated side plates installed parallel to each other, and a swingable connecting member connects the lever and the pivot shaft. is inserted between the two side plates of the hook, and the connecting member engages with a pin installed between the side plates at a position close to the pivot shaft of the hook to swing the hook in the unlocking direction. It is something.

The pivot shaft of the hook and the pin that engages with the connecting member are close to each other, and the hook at the end of the hook swings greatly even with a small swing of the connecting member, so even if the hook is large, it will not lock with the lock receiver. can be easily unlocked.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, 1 is a skylight, and 2 is an opening frame. A skylight lock A according to this invention is attached to the skylight 1, and a lock holder B is attached to the opening frame 2.

Lock A for a skylight includes a case 3, a hook 4 which is swingably pivoted to the case 3 by a connecting pin 8 which is a pivot shaft, and has a hook portion 6 which is engaged with a lock receiver B, and a pivot shaft. a connecting member 7 whose one end is swingably pivoted to the case 3 by a connecting pin 8 and connects the lever 9;
and a spring 1 which is stretched between the case 3 and the hook 4 and biases the hook 4 in the direction of locking with the lock receiver B.
It is equipped with 0.

The case 3 is fixed to a bracket 5 fixed to the skylight 1. Case 3 is two parallel plates 3
a, 3a, two plates 3
A connecting pin 8, a stop pin 11, and a spring locking pin 12 are installed between a and 3a. Case 3
A synthetic resin spacer 13 is interposed between two plates 3a on the opening frame 2 side.

The hook 4 is also composed of two side plates 4a, 4a, and a synthetic resin spacer 14 is interposed between the two side plates 4a, 4a. A hook portion 6 protrudes from the lower part of the hook 4 on the side of the opening frame 2. At the lower end of the hook 4, a spacer 14 slightly protrudes continuously from the lower surface of the hook portion 6. The upper part of the spacer 14 is formed by two side plates 4a, 4.
There are two parallel leg pieces 16, 16 extending along a. The connecting pin 8 installed between the two plates 3a, 3a of the case 3 also passes through the two side plates 4a, 4a of the hook 4 and the leg pieces 16, 16 of the spacer 14, so that the hook 4 is connected to the pin 8. It is possible to swing around the axis. two side plates 4a of the hook 4,
4a and between the leg pieces 16, 16, one end of the connecting member 7, which is a long plate, is inserted, and the connecting pin 8 passes through the end, and the connecting member 7 is inserted around the pin 8 as an axis.
can be swung. Connecting pin 8 of hook 4
The pin 17 is connected to the side plates 4a, 4 at a position close to
It is constructed between a. One side of the connecting member 7 can be engaged with the pin 17. A spring locking pin 18 is installed below the connecting pin 8 between the side plates 4a, 4a, and a spring 10 is hung between it and the spring locking pin 12 of the case 3. The spring 10 connects the hook 4 to the opening frame 2.
It is biased towards the side.

The skylight locks A as described above are fixed to the stile of the skylight 1 at appropriate intervals on the left and right sides. Lock A for both skylights,
A lever 9 is attached between the ends of the connecting members 7, 7 of A, and the connecting members 7, 7 are connected to the lever 9 and the connecting pins 8, 8.
are connected.

Lock holders B and B are fixed to the opening frame 2 in correspondence with skylight locks A and A. The lock receiver B consists of a bracket 19 bent into a U-shape and a locking pin 20.

Next, the state of use of the skylight lock A according to this invention will be explained.

When unlocking, the lever 9 is pushed up using the operating rod 21. The connecting member 7 having the lever 9 fixed to its end rotates around the connecting pin 8. A pin 17 is installed between the side plates 4a, 4a of the hook 4 in the vicinity of the connecting pin 8, and as the connecting member 7 rotates,
The hook 4 also rotates around the connecting pin 8. The connecting pin 8 and pin 17 are close to each other, and even if the connecting member 7 rotates slightly, the hook 4 will rotate greatly, and even if the hook 6 at the tip protrudes greatly, it can be easily removed from the locking pin 20 of the lock receiver B. It will come off.

When closing and locking the skylight 1, the operation rod 21 is hooked onto the lever 9 to lower the skylight 1. Connecting material 7,
7 comes into contact with the stop pins 11, 11 and is prevented from rotating. The lower end of the hook 4 is the locking pin 20 of the lock receiver B.
Then, the lower end surface of the spacer 14 contacts and slides, and the hook 4 swings about the connecting pin 8 against the biasing force of the spring 10. After passing the locking pin 20, the hook 4 is returned to its original position by the biasing force of the spring 10 and is locked.

Effects of the invention This invention has the above-mentioned configuration, in which a connecting member is inserted between the two side plates of the hook to connect the lever and the pivot shaft, and when the connecting member is close to the pivot shaft of the hook, the linking member is inserted between the side plates. The hook engages with a pin installed in the lock to swing the hook in the unlocking direction.

Therefore, even if the amount of lift of the lever is small, the amount of movement of the hook can be increased. Therefore, the engagement between the hook and the lock receiver is deepened, so that the skylight can be reliably locked.

It can be stored inside the case without the need to extend the rear end of the hook, making the lock itself compact.
The appearance is also good.

If the spacer of the hook is made of synthetic resin and its lower end protrudes slightly beyond the side plate, the spacer will come into contact with the locking pin of the lock receiver when locking, allowing smooth locking.
