Description

[0001]
[Industrial application fields]
The present invention relates to a connector having a length adjusting function by joining both ends of a belt-like body.
[0002]
[Prior art]
Materials intended for bundling and restraining things are flexible and take a thin and wide band shape in consideration of ease of use. Typical examples include strips for packing materials for consumables, belts for hanging materials for clothes such as belts and hangers, and lowering tools used for bags, etc. There are direct means that do not use a connection tool and indirect means that use it.
[0003]
In the case of a string mainly used for packing or the like, a direct means is used to apply tension so that the package of the object is not collapsed, to directly connect the strings without loosening, and to disconnect the knots and the subsequent parts. When the brace is the main purpose, it is used repeatedly over a long period of time, and in most cases, an indirect means is used through a fitting with a length adjusting function. The material is made by applying natural or synthetic fibers or leather to the belt and using metal or synthetic resin for the connection.
[0004]
[Problems to be solved by the invention]
A connection tool is indispensable for applications that require length adjustment in strips that are used repeatedly, but when the length adjustment structure of the connection tool is viewed in relation to the belt and connector, fine adjustment is effective using friction. There are some things that are not good, and there is no importance on versatility that uses a locking point and fine adjustment is not effective, but each has the following problems.
[0005]
The problem is that when a person operates a connector, it needs to be in a stationary state and use both hands, and if the combination of the structure of the connector and the material of the strip is not appropriate, the displacement will occur during use. It is difficult to wake up and adjust in the dark. This tendency is a problem common to connecting devices such as buckles, hook-and-eye stoppers, and adjusters, and the range of adjustment is limited particularly in the combination of a belt and a buckle.
[0006]
[Means for Solving the Problems]
An object of the present invention is to provide a connector with an adjustment function of a belt-like body that solves the above-described problems.
[0007]

It is a section function fitting.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The connecting device of the present invention is a separable type consisting of male and female members, the male member is a combination of a fixed member and a movable member, and has various functions for preventing the slack of the belt and adjusting the length. This is a structure in which a fitting portion that is easy to attach and detach and is surely integrated is formed.
[0009]
A male member consisting of both a fixed member and a movable member is formed with a plurality of holes in both members and pin-coupled to allow the movable member to rotate with respect to the fixed member. The structure is sufficiently wound around the periphery. When a tension is applied to the belt-like body by this structure, a synergistic effect between the tension cutting function generated at the folded portion of the belt-like body and the frictional force acting between the belt-like bodies is born, and the connector is given a strong locking function.
[0010]
When the movable member is opened in a V shape, the locking is released and the length adjustment is facilitated. At this time, if the protrusion around the hinge of the movable member is moved until it passes through the tongue of the fixed member, the movable member will not return to its original state by itself, and adjustment work such as passing and pulling out the belt-shaped body becomes easy. Of course, the adjustment is easy in the state where no tension is applied to the belt-like body.
[0011]
The male and female members of the connector are each provided with a fitting portion, and the fitting portion structure forms a bending / extending portion with a protrusion for engagement that gives elasticity to the male member, and guides this protrusion into the body of the female member. Thus, a groove for guiding the engagement to the notch is provided, and after the male and female members are fitted with one touch, the engagement of the protrusion can be confirmed. In addition, when the bent portion viewed from the side hole of the body is pressed inward and pulled in the fitted state, the protrusion is released from the cut and the engagement is released.
[0012]
With the structure described above, the operation of fitting the connector and adjusting the length of the band-like body has become easy regardless of light and dark. The material used for the connector may be a metal, but it is desirable to use a synthetic resin unless strength or heat resistance is particularly required. By doing so, the moldability reduces the manufacturing cost and the elasticity obtained after molding. The physical properties such as strength and weight can sufficiently satisfy the usage conditions.
[0013]
[Action]
The present invention relates to a male / female connector, in which a male member is connected to both a fixed member and a movable member by a hinge, a through-hole of a belt-like body with a locking function is provided on both members, and the female member is connected with a one-touch connection. To do.
[0014]
【Example】
FIG. 1 is an assembled perspective view of the connector 2, FIG. 2 is a perspective view of the connector with the strip 1 attached to both ends, separated into a male member 3 and a female member 31, and FIGS. 3A and 3B are in a fitted state. FIG. 4 (A, B) shows the front and back surfaces of the connection tool, and FIG. 5 (A, B, C) shows the engagement when the connection tool is fitted. The state is shown in three stages.
[0015]
As shown in FIG. 1, the connection tool 2 is composed of a male member 3 and a female member 31 each including a fixed member 4 and a movable member 21. As shown in FIG. 2, when the connecting tool pushes and pulls the back 16 of the bending / extending portion 15 of the male member protruding from the side hole 36 of the female member inward in the direction of the arrow and pulls it inward, as shown in FIG. The male and female members of the connector are easily separated.
[0016]
As shown in FIGS. 2 and 3 (A, B), the fixing member 4 forms a frame with a front end member 5, a rear end member 6, and a side member 7, and a bottom with a hole 8 and a tongue piece 9 in the frame. The material 10 has a recess and a pin hole 12, and the rear end member is provided with a fitting portion with the movable member 21. This fitting portion has a protrusion 13 on the rear end material, and an elastic bending portion 15 is extended from both ends of the protrusion 14 with an M-shape as a whole, and the tip V-shaped portion 17 has a strong elasticity. The end material inner lower end 18 is finished at an acute angle, and the prevention of loosening caused by bending the band 1 is improved.
[0017]
The movable member 21 includes a front end member 22, a center member 23, a rear end member 24, a side member 25, a front hole 26 between each member, a rear hole 27, and pins 28 at both ends. As shown in FIG. 3 (B), when the movable member is opened in a V-shape, the protrusion 29 on the lower surface of the rear end member pushes down the tongue piece 9 to move the movable member after passing. Therefore, the belt-like body 1 can be easily passed through the holes 8, 26 and 27. Edges of each material in contact with the belt-like body were in an edged state to prevent loosening.
[0018]
The relationship between the holes in the male member 3 is such that the central member 23 of the movable member 21 is positioned substantially at the center of the hole 8 of the fixed member 4 so that the strip 1 can be easily bent between the rear hole 27 and the bottom member 10. It is the structure which arranged the hollow in. As shown in FIGS. 2 and 3 (A, B), the female member 31 includes a body 32 having a cavity 34 therein, an opening 33 that fits with the male member at one end of the body, and a strip at the other end. The connection material 40 which connects is provided.
[0019]
The female member 31 is provided with a guide groove 35 directed upward and downward from the opening 33 toward the cavity 34 in the body 32, and the projection 14 of the male member 3 is guided to the notch 38 in the engagement position inside the body by the guide groove. Moreover, since the side hole 36 which leads to the cavity is formed in the portion where both sides of the body are recessed, when the male and female members are fitted, the bent and extended portion 15 of the male member is exposed from the side hole, and as shown in FIG. The back 16 of the bending portion is easy to push.
[0020]
The fitting operation of the male and female members 3 and 31 will be described. FIG. 5 (A) is before fitting, FIG. 5 (B) is being fitted, and FIG. 5 (C) is after fitting, and when the male member protrusion 14 is advanced to the vertical guide groove 35 of the female member, When the bent portion 15 is shrunk inward along the inclination of the guide groove and the V-shaped portion 17 is deformed until the protrusion 13 of the rear end member 6 and the opening 33 are in contact with each other, the protrusion falls on the notch 38 at the front end of the guide groove. When the joint is completed, the flexion and extension will return to its original shape. The completion time may be confirmed by checking the sound at the time of engagement or the observation window 37.
[0021]
To release the engagement of the male and female members 3 and 31 from the state of FIG. 5C, the back 16 of the bent portion 15 of the male member exposed from the side hole 36 of the body 32 of the female member faces inward (arrow). When the force is applied and pushed, the protrusion 14 is pushed out from the notch 38 as shown by the dotted line, and when the male and female members are pulled to the left and right, they are separated to return to the state of FIG. 5 (B) to FIG. 5 (A).
[0022]
The strip 1 is connected through the connector 2 as shown by the dotted line in FIG. That is, the belt-like body is bent at an acute angle by the front end member 5 of the fixed member 4, and then passes through the front hole 26 and the rear hole 27 of the movable member 21, and the center member 23 is obtained by the effect of the depression on the bottom member 10 on the fixed member side. Wraps in a loop shape, exerts frictional force with sufficient wrapping due to the tension acting on the belt, and exerts an excellent anti-loosening effect with the tension cut acting on the folded portion, so that no deviation occurs.
[0023]
The length of the strip 1 can be adjusted regardless of the state of the connector 2. When no tension is applied to the belt-like body, the movable member 21 is easy to open in a V shape, and when the movable member is opened, the belt-like body is also pulled out and easily adjusted. When the tension is applied, the belt-shaped body wound around the central member 23 of the movable member is pulled out in advance and the movable member 21 is opened to facilitate adjustment. In addition, the adjustment does not need to be stationary and can be sufficiently adjusted regardless of the surrounding light and darkness.
[0024]
【The invention's effect】
The following effects were obtained by using the connector with the function of adjusting the length of the band according to the present invention.
(1) The connection tool is a split type that can be attached and detached with a single touch, making it easy to handle.
