KR100246552B1 - Goggles with band adjustment one-touch buckle - Google Patents

Abstract

One-touch buckle (patent application number: 97-37774) of the patented water glasses uses two iron pins (7a, 8a) to combine the components, so the time required to produce the product decreases productivity and exposes the buckle. The appearance was complicated, and the surface of the band was flat, so it tended to loosen slightly by pulling the band strongly.

In order to solve the problem, the present invention provides a band support rod 18 integrated with a buckle instead of an iron pin, a band fixing hill 17b, and a band 19 to the band connecting portion 16, thereby improving productivity and design. The problem was solved, and a plurality of irregularities (15a) were formed on the surface of the elastic band at regular intervals, so that the irregularities pushed the band fixing hill to automatically close the lid, and at the same time, the band was not pulled out even when the band was pulled strongly.

Description

Goggles with band adjustment one-touch buckle

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to snorkels with easy adjustment of the length of the band, and more particularly, to snorkels with a band-adjustable one-touch buckle that can provide a user's most desired fit with one band operation.

In conventional water goggles, in order to adjust the length of the band, the elastic band is placed in the longitudinal opening formed in the outer surface portion of the lens frame integrally formed with the lens portion, or the band is more firmly in the longitudinal opening of the lens frame. The square tubular connecting fixture was attached to the lens frame and the connection portion of the band so as not to be fixed and removed so that the band was pressed into the opening of the lens frame by pressing the square tubular connecting fixture.

However, in a water goggle having a band adjusting device configured by adding a square tubular connecting fixture to the lens frame and the band connecting portion, the thickness of the elastic band worn around the head in actual use becomes thinner than the thickness before wearing, so that the pressure of the band of the square tubular connecting fixture is applied. Not only does the effect drop, but water acts as a lubricant between the bands, thereby reducing the coefficient of friction between the band and the lens frame, thereby introducing water into the lens after swimming for a long time. In addition, when wearing the conventional goggles, in order to achieve the optimal wearing state, the user has to inconvenience the need to adjust the band length of the goggles while repeatedly removing the goggles.

In order to solve such problems and inconveniences, the water glasses band adjustment one-touch buckle of the applicant's Korean Patent Application No. 97-37774 has a lens frame as shown in FIGS. 1 and 2 attached to the present specification. The band supporting iron pin 8a is fixed perpendicularly to the longitudinal direction of the band at the outer end of (2), and the band fixing clamp 7b is easy to press the band against the band supporting iron pin 8a. The slide groove 7 is formed at a point so that the band fixing claw 7b can travel along the slide groove.

The above-mentioned problems have been solved through such a configuration. However, assembling the buckle composed of the oyster and the iron pin takes a lot of time, so the productivity is low, and the interior of the buckle is exposed, which makes the exterior unsuitable for design-sensitive glasses. As well as forming, because the surface is using a flat band there is still a problem that the band is slightly loosened when the band is pulled strongly.

The present invention is to solve the productivity problems, appearance problems and functional problems of the water glasses band adjustment one-touch buckle of the Korean Patent Application No. 97-37774, specifically, shorten the time required to assemble the buckle of the glasses To increase productivity, and to cover the part of the complex buckle exposed in the conventional buckle to build a simple design of the glasses, while installing a large number of ridges on the surface of the band to automatically fix the band And at the same time it is an object of the present invention to provide a goggles with an improved band adjustment one-touch buckle does not loosen even when the band is pulled strongly.

Since the same band adjustment one-touch buckle is provided at both ends of the lens assembly 13, only one band adjustment one-touch buckle will be described below. The buckle is band-connected body 19a and a band-connected lid 19 that slides on the band-connected body to form a band fixed position or a first position and a band released position or a second position relative to the band-connected body 19a. It includes. The band connecting portion main body 19a and the band connecting lid 19 are each integrally formed of, for example, plastic.

As can be seen from FIG. 4, the band connection body 19a is an interlocking fixing piece (not shown) which will be described later with the lens frame 12 interposed on the outer end of the both lens portions 11. ) And the projections 30 are forcibly fitted. The band connection main body 19a is divided into three zones, that is, two long slide grooves 17 for sliding in which the band connection lid guide bars of the band connection lid described later are inserted in the longitudinal direction, respectively, and are spaced apart in parallel. A band connection section 24 having band supporting means connected to both side portions, for example, a band support rod 18 so that the side portions and the band can be worn, and the band connecting body 19a are the outer ends of the lens. A fastening section 26 having a fixing piece (not shown) formed at a bottom surface thereof so as to be fixed to the bottom surface, and a band connecting lid 19 which is located between the band connecting section 24 and the fastening section 26 and is described below so as not to be detached. Bar guide groove 20a to which the separation prevention bar 20 'of the band connection cap is coupled is configured as a separation prevention zone 25 formed along both sides.

The anti-separation zone 25 has a plate-shaped base plate and a ridge 25 " protruding narrower than the base plate along the center of the base plate, and guide grooves 20a are provided on both sides of the ridge. The transition portion between the band connection zone 24 and the departure prevention zone 25 and the transition portion between the departure prevention zone 25 and the fastening zone 26 will be described later. Each stop surface for preventing the sliding of 20 '), and thus, the anti-separation rod 20' of the band connection cap slides along the guide groove 20a of the anti-separation zone of the band connection body. Sliding movement is impeded by the stop surfaces to take the first position or the band fixing position and the second position or the band disengaging position The process of assembling the band connecting cap 19 to the band connecting body 19a is easier. In order to let the above guide One of the (20a) may be formed with cutouts (20a ').

On the other hand, the outer surface 16 of the fastening zone 26 is curved to form a smooth continuous surface with the outer surface of the lens portion 11 into which the band connection body is fitted (see FIG. 3). According to a preferred embodiment of the present invention, the band connection zone 19 and the separation prevention zone are prevented because the band connection cover 19 is covered only in the band connection body 24 and the separation prevention zone 25 among the band connection body 19a. The zone as a whole is lower than the highest height of the fastening zone. Thus, when the band connecting lid is fitted on the band connecting body, the outer surface of the fastening section of the band connecting body and the outer surface of the band connecting lid form a smooth smooth surface as shown in FIG. Provide the appearance of the design.

The band connection lid 19 is a generally flat rectangular top plate portion 27 that is generally sized to cover the band connection zone and the breakaway prevention zone, and an extension extending with a large curvature downwardly from the top plate portion 27 back and forth. It is composed of a portion 28. According to this preferred embodiment, the corners (first corners) of the corners of the upper plate portion 27 opposite the extension portion 28 extend downward from both corners thereof and face each other from the inner surface at the free ends. Two extensions 20 are provided with a breakaway bar 20 'extending vertically. Meanwhile, a band fixing means protruding downwardly along the entire edge from the bottom surface of the upper plate portion 27 at the corner (second corner) bordering the extension portion 28 among the corners of the upper plate portion, For example, ribs 17b are provided. Both sides of the rib 17b have guide bars 17a extending vertically outward therefrom. The rib 17b serves to squeeze and fix the band 15 against the band support rod 18 as will be understood from the operation description below. The band fixing rib 17b is directly perpendicular to the supporting rod 18 with the band supporting rod 18 interposed with the band supporting rod 18 when the band connecting lid 19 is in the band fixing position or the second position. Located on the upper side, it is formed on the band connection cap 19 so as to be spaced apart from the band support rod 18 at intervals for pressing at least half of the elastic band. The extension 28 protruding downwardly and rearwardly from the second edge of the upper plate portion 27 is bent slightly inward as shown in FIG. 4, so that the band connection lid 19 is formed with the band connection body ( When fitted on 19a), the band connection cap 19 is entirely streamlined. A triangular protrusion 21 is formed on the outer surface of the upper plate portion 27 of the band connecting lid 19 so that the band connecting lid 19 can be easily pushed and moved with a finger or the like.

By the configuration as described above, when the band connecting part cover 19 is fitted on the band connecting part main body 19a, the separation preventing rod 20 'is fitted into the guide groove 20a and the guide bar 17a slides. Fitted into the grooves 17, respectively, the band connecting portion 19 slides along the guide grooves and the slide grooves.

On the other hand, according to a preferred embodiment of the present invention, the band connecting body is forcibly fitted on the outer ends of both lens portions 11. To this end, two projections 30 are formed on the outer ends of both lens portions 11 to which the band connection body 19a is forcibly fitted. A fixing piece (not shown) which is forcibly fitted between the two opposing protrusions is provided on the bottom surface of the fastening section 26 of the band connecting body 19a. The opposite side surfaces of the two projections which engage the fixing piece when the band connection main body 19a is received form an inclined surface so that the cross-sectional area becomes narrow toward the lens surface. The fixing piece has a complementary shape that can be matched between the projections (30). In order to more firmly fix the band connection body 19a, a latch 29 may be further provided on the lens end surface. A locking jaw (not shown) on which the latch 29 is engaged is provided on the bottom surface of the fastening zone 26.

A plurality of ridges 15a are formed on the surfaces of the predetermined length portions of both ends of the elastic band 15 at regular intervals along the length of the elastic band and extending in the width direction of the elastic band. The band fixing means, that is, the ridge 15a of the elastic band which is installed to face the rib 17b, pulls the end of the band and at the moment the band contracts due to the elasticity of the band, the band ridge 15a is the band fixing rib. It has a height high enough to push (17b) in.

Hereinafter, the cooperative action of the band support rod 18 of the band connection unit body 19a and the rib 17b of the band connection cover 19, which plays an important role in adjusting the band length of the band adjustment one-touch buckle (band connection portion) of the present invention 5 and 6 will be described in more detail. The remaining configuration of the band connecting unit body 19a except for the support rod 18 is omitted for clarity.

When the goggle wearer wears the elastic band loosely and pulls both ends of the band from behind the head until the goggles are properly squeezed around the eyes, the closed band connector lid 19 is simultaneously retracted from the band 15 with the band. When the wearer feels the most appropriate condition, when the band is released, the band connecting lid is moved in the direction of the arrow E as the ridge 15a installed on the surface of the band is caught by the band fixing rib 17b. As the band fixing rib 17b is positioned just above the band supporting rod 18, the band is automatically pressed and fixed therebetween.

6 shows that between the support rod 18 and the rib 17b as the ridge 15a comes into contact with the rib 17b when both ends of the band 15 are pulled out so that the band connecting lid 19 moves in the direction of the arrow F. FIG. Shows the state in which the band is loosened (or the state where the band connecting cap is in the second position) with the distance of.

Alternatively, the band fixing rib 17b moves away from the band support rod 18 by pushing back the triangular projection 21 formed on the outer surface of the band connection cap with a finger without pulling both ends of the band. It is released from the crimp fixed state.

7 is an exploded perspective view of another embodiment of the band adjustment one-touch buckle to which the present invention is applied. A long spring accommodating groove 22 is formed along the center of the ridge provided in the separation preventing zone of the band connecting portion main body 19a of FIG. 5, and the spring 23 is installed therein. A spring pusher 22a is also provided which extends downward from the center between the two rods 20 'to the bottom face of the spring receiving groove at the leading end of the band connection lid. When the band connection body and the band connection lid are engaged, the back of the spring pusher 22a abuts against the left end of the spring, as seen in FIG. Accordingly, when the elastic band is pulled, the spring pusher 22a of the band connecting part lid 19 is pushed out together with the elastic band while pressing the spring 23, but if the elastic band is not pulled, the lid is automatically closed by the restoring force of the spring and the band. do. According to this configuration, in addition to the restoring force of the band, not only the band connecting portion lid 19 quickly moves to the band fixing position by the restoring force of the band, but also the band is more strongly between the band fixing rib 17b and the band supporting rod 18. It is compressed and fixed.

The present invention described above can obtain the following effects.

First, unlike the form of the band adjustment one-touch buckle of the conventional glasses goggles and iron pins, the components of the buckle are combined, the plastic formed integrally with the band connection body 19a and the band connection cap 19 to act as an iron pin Since the band support rod 18 and the band connecting portion lid guide bar 17a take its role, the time-consuming iron pin assembly work is eliminated, so that the effect can be greatly improved in productivity.

Second, the conventional band-adjustable one-touch buckle is not simple in appearance because it exposes a complex internal structure, the present invention was installed so that the design looks simple by installing a band connecting portion lid 19 so that this complex inside is not visible.

Third, by forming a plurality of ridges on the surface of the band, it is possible to obtain the effect of fixing the band firmly and automatically using only one hand.

Fourth, by installing a spring on the band-adjustable one-touch buckle of the goggles so that the band connection cap 19 is automatically closed when fixing the band, when fixing the band in the existing band-adjustable one-touch buckle by using the band to fix the band Discomfort to push (7b) toward the band support iron pin (8a) has been eliminated.
