Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is mainly used to securely hold and secure infants in the seat of strollers, etc. This relates to a buckle used for a simple safety belt to keep the vehicle in place.

0002

[Conventional technology]

These simple safety belts keep infants safe when traveling on roads, etc. It has the role of holding and fixing it to the seat, but it depends on the infant's developmental state of wisdom. In some cases, the infant may unlock the buckle without permission. this Because of this, infants and toddlers may leave the stroller alone while their parents are not looking. Otherwise, you may lose your balance in the seat and cause an accident such as the baby stroller falling over. There is that.

0003

[Problem that the idea aims to solve]

However, if the locking means of the buckle is complicated, the cost will increase. Moreover, it is difficult for parents to attach and detach the belt, making it difficult to handle. The problem remains.

0004

[Purpose of invention]

This invention was developed based on the above circumstances, and normally the belt is locked in a simple lock state. can be attached and detached, and a secondary lock can be used when the parent leaves the stroller etc. By performing the buckle lock operation, infants and children will not be able to unlock the buckle by themselves. The aim is to provide an improved buckle.

[0005]

[Means to solve the problem]

Therefore, in the present invention, as shown in the illustrated embodiment, the engaging portion ( 1A) and insert the tip of the insertion connector (1) into the insertion opening (3A) of the buckle body (3). and insert the engaging piece (4) pivotally supported on the buckle main body (3) into the engaging part (1A ) and is removably engaged with the engagement piece (4) by the elastic force of the elastic support mechanism (6) against the engagement piece (4). In the buckle that maintains the engaged state, the buckle body (3) A secondary engagement piece (8) is slidably disposed on the engagement piece (4). 1A), the secondary engagement piece (8) is engaged with the engagement piece (4). and configured to prevent the engaging piece (4) from rotating around the pivot. There is.

[0006]

[Effect]

Therefore, normally, the insertion connector (1) is simply inserted into the insertion opening (3A) of the buckle body (3). ), and engages the engaging portion (1A) against the elastic holding force of the elastic holding mechanism (6). It is only necessary to engage the mating piece (4), but if necessary, secondary engagement may be performed in the above engaged state. The piece (8) can stop the movement of the engaging piece (4) and keep the buckle locked. Ru. For this reason, safety can be achieved without significantly increasing costs. In addition, the buckle can be easily engaged and disengaged under normal usage conditions.

【Example】

Hereinafter, the present invention will be specifically explained based on illustrated embodiments. In the figure, the code 1 is It is an insertion connector with an engaging part 1A at the tip, and an attachment part for the belt 2 at the base end. It is equipped with 1B. On the other hand, it is equipped with an insertion opening 3A for receiving the tip of the insertion connector 1. The buckle body 3 that has been inserted engages the engaging portion 1A at the final insertion end of the insertion connector 1. For example, a pivot pin 5 or other pivot lever is attached to the engaging piece 4 on both sides 3B, 3B. It is supported using steps. In this embodiment, the engaging piece 4 is the engaging portion 1A. The lid-shaped engagement piece main body 4B has a hook 4A on the back side that removably engages with the It is equipped with a prismatic secondary engagement part 4C around the pivot, and the engagement piece main body 4B has an upper The front surface of the buckle main body 3 is nicely covered. The above-mentioned engaging piece 4 is the engaging piece main body. A spring seat 4D is formed protrudingly on the back surface of 4B, and correspondingly, a spring catcher 4D is A tongue-shaped spring 6 as a structure is bordered by a U-shaped slit and is attached to the bag. It is integrally formed at the center of the back side of the vehicle main body 3.

[0008] In particular, in the present invention, the pivot pin is provided on one side 3B of the buckle main body 3. A slide guide 7 is formed extending in a direction perpendicular to the longitudinal direction of 5. A secondary engagement piece 8 is slidably provided so as to be able to move along this line. This two The next engagement piece 8 is located inside the buckle main body 3 and has an integral engagement elastic tongue piece 8A. It is formed in The engaging elastic tongue piece 8A is such that the engaging piece 4 is connected to its hook. 4A is engaged with the engaging portion 1A, the secondary engaging piece 8 engages with the slide guard. When sliding along the side of the pivot pin 5, it is guided below the secondary engagement part 4C and Secondary engagement with the engagement piece 4 is possible. In addition, if necessary, please contact the above person. The joint elastic tongue piece 8A is provided with a notch 8B on the back side of its tip, and correspondingly, the above-mentioned In the buckle body 3, the secondary engagement pieces 8 have come to both moving ends of the slide guide 7. At this time, an engagement slot 3C is formed which engages with the notch 8B. In addition, in the figure, No. 3D is a mounting part to which the end of the belt is attached.

[0009] In such a configuration, in order to safely hold and secure an infant in a stroller, etc., When attaching the safety belt, simply insert the tip of the insertion connector 1 into the insertion opening 3A. For example, the hook 4A engages with the engaging portion 1A due to the action of the spring 6, and the buckle is locked. state. To release this, pivot the engaging piece 4 against the spring 6. In order to rotate around the pin 5, if the engaging piece main body 4B is pushed from the front, the hook 4A releases the engagement with the engaging portion 1A. In this state, from the insertion port A to the above All you have to do is pull out the insertion connector 1.

0010 Also, when parents leave the stroller, please follow the slide guide 7 above. slide the secondary engagement piece 8, and place the engagement elastic tongue piece 8A under the secondary engagement part 4C. Induce. This prevents the engaging piece 4 from rotating around the pivot pin 5. Therefore, the engagement between the hook 4A and the engaging portion 1A is maintained. Therefore, even if , infants, with their developing wisdom, know how to release the buckle and engage it. Attempting to release the engagement between the hook 4A and the engaging portion 1A by pushing the piece 4 from the front. However, this can be prevented and the safety belt can be prevented from being accidentally removed.

[0011] Of course, the secondary engagement piece 8 can be slid in the opposite direction with respect to the slide guide 7. If so, the buckle can be easily returned to the previous simple engaged state.

0012 In the above embodiment, the secondary engagement piece 8 is formed on the one side piece 3B of the buckle main body 3. The movement of the engaging piece 4 is prevented by sliding along the slide guide 7 that has been However, in a different configuration, the buckle body 3 is configured to slide against the buckle body 3. Of course, it is also a good thing.

[0013]

[Effect of the idea]

As detailed above, the present invention has a secondary engagement piece that is slidably attached to the buckle body. The engaging piece arranged and pivotally supported on the buckle body connects to the connector inserted into the buckle body. In the state where the secondary engaging piece is engaged with the engaging portion, the secondary engaging piece is engaged with the engaging piece, and the Since the engaging piece is configured to prevent rotational movement around the pivot, the engaging shape is In this state, the secondary engaging piece stops the movement of the above engaging piece and double locks the buckle. to maintain a sufficient lock state. For this reason, there is no significant cost increase. It is possible to ensure sufficient safety without causing damage to the battery, and the battery does not deteriorate under normal usage conditions. You can easily engage and disengage the vehicle.
