[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the connection of a bridge and an eye cup in goggles, the connection of both cups of a bra, the connection of both bands such as a length-adjustable hair band composed of a plurality of bands, a headphone band, and the band of a band-type opening diameter adjusting hat. The present invention relates to a connection device for connecting two members of various articles, such as a connection, a belt fastening shoe, a belt such as sandals, and the like, so that the distance between the members can be adjusted.
[0002]
[Prior art]
Conventionally, for example, as a distance-adjustable connection device between a bridge and an eyecup in goggles, a plurality of locking projections are protruded from both ends of one bridge to a rectangular connection plate main body at intervals in the front-rear direction. Each of the rubber connecting plates is extended, and each of the other two eyecups has a bracket provided with a locking hole through which the connecting plate body can be inserted and removed. Forcibly press-deform the locking projection of the board and insert it into the retaining state, and a plurality of locking pieces projecting from both ends of one bridge to the narrow board in the horizontal direction in the front and rear direction A synthetic resin connecting plate formed at an interval extends from each other, and can be inserted into brackets projecting from the other two eyecups when the locking pieces of the connecting plate are oriented vertically. Pierced holes It is known that the locking piece portion of the connecting plate is vertically inserted into the locked hole, and then the locking piece portion is rotated 90 degrees in the horizontal direction to keep the locking piece from falling out. I have.
[0003]
However, the former conventional device has a drawback that when the connection plate is repeatedly engaged and disengaged from the above-mentioned locked hole for adjusting the distance between the two eye cups, the locking projection is worn and damaged, and the locking projection is liable to be locked. In addition, the latter conventional device has a drawback that the locking piece is easily detached from the locked hole when the goggles are not used, such as when the goggles are removed from the face. there were.

It includes one assembled in a predetermined position, or one in which an elastic locking plate is integrally formed with the locking means.
Hereinafter, the present invention will be described with reference to the drawings, in which an embodiment of a connecting device for connecting a bridge and an eyecup in goggles is implemented.
[0007]
【Example】
In FIG. 1, brackets (2) and (2) provided with locking means are respectively protruded from inner ends of two eyecups (1) and (1) of goggles, and both brackets (2) and (2) are provided. The connecting plates provided at both ends of the bridge (3) are inserted into the locking means of (3), respectively, so as to be detachably locked, whereby both eyecups (1) and (1) are connected by the bridge (3). It is.
[0008]
First, the connecting plate of the bridge (3) will be described. In FIG. 4, a bridge (3) is a rectangular plate made of a relatively hard synthetic resin. From both ends, a rectangular plate-like connecting plate of the same material having a smaller width and thickness than the bridge (3) is used. (4) and (4) are respectively extended substantially in the same plane as the bridge (3) in the direction of insertion into the locking means, and on the lower surfaces of the connecting plates (4) and (4), The locked grooves (5) and (5) of the book are formed at appropriate intervals along the insertion direction.
[0009]
The locking means of the bracket (2) is as follows. In FIGS. 5, 6 and 7, through-holes (6) which are formed in the bracket (2) and have a rectangular cross section that is long in a horizontal section and penetrate in a direction substantially parallel to the surface of the eyecup (1) and partially open at the center of the upper surface. ), The bottom plate of the through hole (6) is formed on the front bottom plate (8) and the rear bottom plate (9) at intervals (7) along the insertion direction, and both bottom plates (8), In the center of (9), the front bottom plate (8) is deep and the rear bottom plate (9) is formed with shallow recesses (10) and (11), respectively.
[0010]
The lock means of this embodiment is an example in which a lock assembly is formed separately and assembled in the through hole (6), and the assembly (12) is made of a relatively hard elastic synthetic resin plate. As shown in FIG. 3, an elastic lock plate (14) having a slightly smaller width than the recesses (10) and (11) extends from the center of the base (13) having a width slightly larger than the width of the through hole (6). At the same time, one locking ridge (15) which can be engaged with and disengaged from the locked grooves (5), (5) of the connecting plate (4) is provided substantially at the middle of the upper surface of the locking plate (14). And the holding plates (16) and (16) extend from both sides of the base (13) to both sides of the lock plate (14), and the holding plates (16) and (16) On the lower surface, claw pieces (17) which can be engaged with the above-mentioned space (7) are provided in a protruding manner.
[0011]
The lock assembly (12) as described above is inserted into the through hole (6) of the bracket (2) as shown in FIG. 8, and the holding plates (16) and (16) are attached to the front and rear bottom plates (16). 8), (9) and their pawls (17), (17) are respectively engaged in the space (7), whereby the elastic locking plate (14) and the holding plate (16) are engaged. ), (16) and the upper plate of the through hole (6), a connecting plate guide hole (6 ') is formed, and the lock plate (14) is supported in a cantilever state and its free end ( Front end) protrudes forward from the guide hole (6 ') in the direction of extension thereof.
[0012]
The operation of the above example will now be described. When connecting the bridge (3) to the eyecup (1), first, in the bracket (2), push the distal end of the lock plate (14) downward with a finger to put the cantilevered lock plate (14) into the recess ( 10) and (11), whereby the locking ridge (15) of the lock plate is retracted downward from the connection plate guide hole (6 '). In this state, the connecting plate (4) of the bridge (3) is inserted into the guide hole (6 ′), and one of the locked grooves (5) and (5) is inserted into the locking ridge (15). When the lock plate (14) is released from its corresponding position, the lock plate (14) is elastically restored to its original linear state, and its locking ridge (15) as shown in FIG. Is locked in the locked groove (5), thereby locking the connecting plate (4) immovably.
[0013]
When changing the distance between the two eyecups (1) and (1) connected by the bridge (3), the front end of the lock plate (14) is pressed to deflect the lock plate (14) downward, thereby locking. The protruding ridge (15) is disengaged from the locked groove (5), and in this state, the connecting plate (4) is advanced and retracted, and a new locked groove (5) is positioned at a position corresponding to the locking ridge (15). Then, the push of the lock plate (14) is released and the locking ridge (15) is locked in the new locked groove (5).
[0014]
FIG. 9 shows an example in which the elastic lock plate is formed integrally with the lock means. The base of the elastic lock plate (14a) is integrally fixed to the rear bottom plate (9a), and the distal end of the lock plate is connected to the connecting plate guide hole (6'a). ) Is an example which is substantially the same as the above example except that it protrudes forward in the extension direction of the above example and corresponds to the front bottom plate (8) of the above example. In this embodiment, substantially the same operation as in the above embodiment is performed.
[0015]
【The invention's effect】
According to the distance adjusting type connection device between the two members of the present invention, the locking portion or the locked portion is engaged without applying any forcible pressure deformation, so that they are mostly worn or damaged. Not only that, even when the product is not in use, the locking of the two members does not come off, so that reliable connection can be maintained. The distance can be easily adjusted by a simple operation of moving in and out, and the use is extremely convenient.
