Description

[Detailed description of the invention] [Field of industrial application] The present invention is used to stably seat an infant in a seat, particularly a baby chair or a stroller, to prevent the infant from falling or moving. This relates to a buckle that is attached to the tip of a fixing belt used for this purpose, and in particular relates to the structure of the buckle that allows two fitting bodies fitted to the buckle body to be easily and accurately removed with one touch. It is.

[Technology background]

The use of seat belts as a means of safely securing a person seated in a seat is extremely common.

The most basic known structure of these seat belts is that a buckle body (female body) and a fitting body (male body) that fits into this buckle body are attached to the tips of two belts, respectively. After the two belts are worn across the user's abdomen, the buckle body attached to the tip of the belt and the fitting body are fitted together and tightened, thereby tightening the buckle body of the user, the infant. One example is a so-called "single harness" type, which is constructed so that the body is stably held without falling off or falling off the seat.

However, when an infant whose body is not yet fully grown and whose feet do not reach the floor surface is seated in a high chair or stroller, a single harness type belt is placed around the infant's abdomen. If the seat is tightened, the child's body may gradually move forward from the waist as the child moves his or her body on the seat surface of the chair or as the stroller swings. It has been pointed out that this reduces the stable gripping effect of the belt.

For this purpose, in addition to the above-mentioned single harness type belt structure, a crotch belt made of a band-shaped body of an appropriate length is raised from the center of the infant's crotch, and the upper end of this crotch belt is attached to the buckle part of the single harness type belt. A structure has been proposed in which the belt is connected so that the belt tightens in a front T-shape, thereby preventing the infant's body (particularly the lumbar region) from moving from the seat surface.

In the case of a structure that uses the above-mentioned crotch bar,
A structure in which a buckle body having fitting holes for fitting bodies at both ends is fixed to the upper end of the crotch belt, and fitting bodies attached to the tips of two waist belts are fitted on both sides of the buckle body. When taking the infant out of the stroller or infant chair (if you want to release the belt), the two waist belts can be connected by releasing the fitting between the fitting body and the buckle body. The crotch belt is separated from the crotch belt, thereby achieving the purpose.

In the case of the above-mentioned structure, if the two fitting bodies are configured so that they can be removed simultaneously with a one-touch operation when releasing the fitting body from the buckle main body, the infant's body can be quickly removed from the seat surface. Therefore, it was desired that such a buckle structure could be created.

In addition, in conventional buckles, the ends of the waist belt and crotch belt are connected to the ends of the buckle body, leaving the buckle body exposed, but recently, due to design requests, buckles have been A buckle mechanism was proposed in which the main body was covered by the upper end of the crotch belt, and a buckle mechanism was proposed in which the two operating bodies could be simultaneously released by one-touch operation. More proposals are needed.

[Purpose of invention]

In view of the above-mentioned circumstances, the present invention is intended to address these problems.In the belt structure in which a crotch belt and a waist belt are combined in a front T-shape, the central part of the top surface of the buckle body is By one-touch pressing operation, the two operating plates mounted facing each other open simultaneously, thereby causing the two fitting bodies fitted to both ends of the buckle body to fit together. The object of the present invention is to provide a buckle configured to be able to reliably release the buckle.

[Key points of the idea]

The present invention consists of a buckle body attached to the tip of a crotch belt that stands up from the seat floor, and a buckle body that is attached to the tip of a waist belt that is separated into two pieces, each of which is detachable from both ends of the buckle body. The buckle main body has fitting holes at both ends for removably fitting the above-mentioned fitting bodies, and a hole bored in the center of the upper surface. The through hole has two operating bodies for engaging and releasing the two removably fitted bodies from both ends of the buckle body.
The key point of the invention is a buckle structure in which front end portions facing each other are close to each other and are pivoted so that they can swing independently.

', and thereby the locking part 33 formed on the rear half of the operating body 3 that sandwiches the support shaft part is always maintained in a horizontal state, and the locking hook formed on the lower surface of the locking part 33 is always maintained in a horizontal state. The portion 33' is designed to maintain engagement with the fitting hole 21' formed in the fitting portion 21 of the fitting body 2.

The fitting body 2 is formed into a substantially concave-convex planar shape by a fitting part 21 that fits into and locks the buckle body 1 and a base part 22 that is exposed to the outside of the buckle body 1. The locking hook portion 33' formed at the base end of the operating body 3 is configured to be removably locked in the fitting hole 21' formed in the center of the fitting portion 21, and the is waist belt B1
It is configured so that the tip can be locked.

Reference numeral 23 denotes a shoulder belt locking portion that is formed to protrude above the base portion 22 so as to have an L-shape in plan, and the elongated rod portion forming the belt locking portion 23 is parallel to this above the buckle body 1. It is formed so that it becomes.

The shoulder belt locking portion 23 described above is used when the locking belt structure is formed into a double harness type, and is pulled out from near the upper end of the backrest of an infant chair, stroller, etc., and placed on the shoulder of the wearer. Shoulder belts B2 and B2, which are brought into contact with each other, are inserted into a loop portion B3 formed at the tip of the shoulder belt B2. (See FIGS. 5 and 6) 4 in the figure is a crotch belt, and the buckle body 1 is attached to the tip.

The means for attaching the buckle main body 1 to the crotch belt 4 is, as illustrated in FIG. Alternatively, a method may be adopted in which a crotch belt locking portion (not shown) is formed on the lower surface of the buckle body 1, and the tip of the crotch belt is inserted and locked into this locking portion.

[Use of invention]

The present invention configured as described above is used in the following manner.

Although the illustrated example shows an example of an infant chair as furniture, the usage method is exactly the same for a stroller or the like.

As illustrated in FIG. 7, the buckle main body 1 wraps the tip of the crotch belt 4 around its circumference to fix and integrate the two so that they will not easily separate.

Further, the tip portions of the waist belts B1, B1 are inserted and locked into the base portions 22, 22 of the fitting bodies 2, 2, respectively.

*Operation for putting on the belt When the infant is seated on the seat, the crotch belt 4 is erected along the crotch of the infant so that the buckle body 1 is positioned on the front abdomen of the user (infant).

Next, tighten the waist belts B1 and B1 from both sides of the infant's back.
are pulled toward the buckle body 1, and then the fitting bodies 2, 2 attached to the tips of the two waist belts are fitted into the fitting bodies 11, 11, respectively, to integrate the two.

The fitting bodies 2, 2 inserted into the backing body 1 are locked in place by a fitting hole 21' formed in the fitting portion 21, and a locking hook portion 33' formed on the underside of the locking portion 33 of the operating body 3 fits into the fitting hole 21', thereby preventing the fitting body 2, 2 from coming loose.

In this case, the operating portion 32 formed at the tip of the operating body 3 is constantly biased upward by the resilient plate 15 that is resiliently erected from the bottom plate of the buckle body 1. As a result, the locking portion 33 located on the opposite side is biased with downward force, and as a result, the locking portion 33
The engagement between the locking hook portion 33' formed on the lower surface of the locking hole 21' and the fitting hole 21' can be maintained even more firmly. (See Figures 3 and 4) *Operation for opening the buckle When opening the fitted body, push down the entire central part of the buckle body 1 downwards with your fingertips.

The two operating bodies 3, 3, which are attached so as to close the through hole 12 formed in the buckle main body, are pivoted so as to be able to swing freely so that their opposing front edges are close to each other. When you perform the operation,
The two opening operation parts 32, 32 are pushed down at the same time, and as a result, the buckle body 1
The mating bodies 2, 2, which were mated and locked from both sides, are instantly released from the locking, and the mating bodies 3, 3 are locked in one-touch.
The lock can be released.
