Description

The present invention relates to a fastener that separably connects and holds a first part and a second part of an adherend.

Clothes such as pants and skirts are often provided with openings and closing parts that are opened and closed when putting on and taking off the clothes. In addition, the first part on one side (for example, the upper front part of the front body) and the second part on the other side (for example, the lower front part of the front body) of the opening/closing part of this garment generally have a slide fastener. is provided, and a fastener is provided for separably connecting and holding the first and second portions.

As one of the above-mentioned fasteners, for example, a fastener called hook and eye or hook hook is known. This hook-and-eye (key hook) usually has a hook member attached to the upper front part of clothing and an eye member (receiving member) attached to the lower front part, and the hook member is hooked onto the eye member. The upper front and lower front of the garment are connected by holding the garment in place.

An example of such hook-and-eye is described in Utility Model Registration No. 3204641 (Patent Document 1). For example, as shown in FIG. 13, the hook-and-eye 80 of Patent Document 1 includes a hook member 81 and an eye member (receiving member) 91. The hook member 81 has a U-shaped overall cross section. The hook member 81 is attached to the fabric 90 by the pair of legs 82 of the hook member 81 penetrating the fabric 90 and engaging with the lower washer 83. The eye member 91 is attached to the fabric 90 by a pair of legs 92 of the eye member 91 penetrating the fabric 90 and engaging with a lower washer 93. The eye member 91 is provided with a gap through which a portion of the hook member 81 can be inserted.

According to Patent Document 1, the hook member 81 is formed so that the length in the horizontal direction is longer than the length (dimension) in the vertical direction for inserting and extracting the hook member 81 into and from the eye member 91. It is said that the entire eye 80 can be made smaller. Further, in Patent Document 1, a temporary fixing means for fixing the hook member 81 to the eye member 91 is provided. He says he won't leave easily.

By the way, for example, Japanese Patent Publication No. 2016-505306 (Patent Document 2) describes a fastener as shown in FIG. A closure device) 100 is described.

The fastener 100 of Patent Document 2 has a magnetic mechanism (magnetic attraction force) between a first closure member 110 attached to one end of the belt and a second closure member 120 attached to the other end of the belt. ) is formed so that it acts. The magnetic mechanism of this magnet supports the sliding movement of the first closure member 110 when the first closure member 110 is slid and connected to the second closure member 120. This facilitates the closing operation (connection operation) of the fastener (closure device) 100.

Utility model registration No. 3204641 Special table 2016-505306 publication

In the conventional general hook and eye or the hook and eye 80 of Patent Document 1 as shown in FIG. In order to separate the eye member from the hook member, it is necessary to hold the hook member side and the eye member side with one hand, respectively, and to insert or remove the hook member into the eye member with both hands. However, in order to improve convenience and operability, it has been desired to be able to connect and separate the fasteners with only one hand.

For example, in nursing care settings, when the person in need of care changes their own clothes, or when an assistant changes the clothes of the person in need of care, elastic pants are often used. If there is a fastener that can be operated with only one hand, it will be possible to easily put on pants with a slide zipper, for example. This allows the person in need of care to have a wider range of clothes to choose from. In this case, the fasteners are not only connected so that they can be connected and separated with only one hand, but also so that the fasteners are not easily separated by the care recipient's movements when putting on clothes. It is also necessary that the current state be maintained stably.

Furthermore, for example, with conventional hook-and-eye systems, if the care recipient's clothes are somewhat large and loose, the hook member and eye member of the hook-and-eye system tend to separate due to loose clothing. was there. On the other hand, in the case of the hook and eye 80 of Patent Document 1, since the hook and eye 80 is provided with a temporary fixing means, the problem of easy separation of the hook member 81 and the eye member 91 is solved, but the temporary fixing means This has the disadvantage that it becomes more difficult to connect and separate the hook-and-eye with only one hand.

In the fastener 100 of Patent Document 2 shown in FIG. 14, when connecting the first closure member 110 and the second closure member 120, the first closure member 110 is aligned with the second closure member 120. Furthermore, the first closure member 110 is slid toward the second closure member 120 while being held down. Accordingly, the first closure member 110 can be connected to the second closure member 120, so that the operation of connecting the fastener 100 can be performed with one hand.

However, when separating the first closure member 110 from the second closure member 120 from the connected state of the fastener 100, the actuation mechanism 121 of the second closure member 120 is moved and the first closure member 110 is further slid. In order to separate the first closure member 110 and the second closure member 120, it may be difficult to separate the fastener 100 with one hand.

In addition, in the fastener 100 of Patent Document 2, the structure of the first closure member 110 and the second closure member 120 is very complicated, leading to an increase in the manufacturing cost of the fastener 100. Further, the fastener 100 of Patent Document 2 is thick due to its structure, so it can be used for products such as belts, but it cannot be used for openings and closing parts of clothing such as pants and skirts. In such cases, it is necessary to make improvements such as making the thickness thinner to the extent that no discomfort occurs when putting on clothes.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to make it possible to easily connect and separate the fasteners with one hand, and to make it possible to easily connect and separate the fasteners with one hand.

Accordingly, it is also possible to attach the plug member 10 and the socket member 20 to an adherend using rivets or the like.

In the fastener 1 of the first embodiment, in which the plug member 10 and the socket member 20 are respectively attached to the upper front part and the lower front part of the front body of the pants, for example, the upper front part of the pants can be grasped with one hand, and the upper front part By bringing the plug member 10 of the lower front part closer to the socket member 20 of the lower front part, the first magnet 6 of the plug member 10 and the second magnet 7 of the socket member 20 are attracted to each other, whereby the plug member 10 and the socket member 20 and can be overlapped and connected in the thickness direction of the fastener 1. Below, the connection operation between the plug member 10 and the socket member 20 will be specifically explained.

In the first embodiment, the top end surface of the hook portion 13 in the plug member 10 is provided with an inclined surface 13c that slopes downward toward the hook tip, and the top end surface of the locking portion 23 in the socket member 20 is provided with an inclined surface 13c that slopes downward toward the hook tip. An inclined surface 23d is provided that slopes downward toward the tip of the locking main body portion 23b. Therefore, the plug member 10 approaches the socket member 20 from the thickness direction due to the attraction force of the first magnet 6 and the second magnet 7, and furthermore, the hook tip of the hook portion 13 of the plug member 10 moves toward the socket member 20. By coming into contact with the locking portion 23, the position of the plug member 10 can be shifted in the vertical direction with respect to the socket member 20 along the slope 13c of the hook portion 13 and the slope 23d of the locking portion 23. Thereby, the hook distal end of the hook portion 13 can get over the distal end of the locking portion 23 and approach the second base portion 22.

Furthermore, after that, the plug member 10 moves vertically due to the adsorption force of the first magnet 6 and the second magnet 7 and returns to its original position, so that the hook tip of the hook part 13 is moved toward the back side of the locking part 23. can be inserted automatically.

For this reason, the plug member 10 becomes difficult to separate from the socket member 20 in the thickness direction, and the connection state between the plug member 10 and the socket member 20 can be stably maintained.

In addition, when the fastener 1 of this embodiment 1 is attached to the upper front and lower front of pants, the fastener 1 is attached to the upper front and lower front of the pants as shown in FIG. This makes it easier to apply a tensile force 8 along the vertical direction. In contrast, in the fastener 1 of the first embodiment, the hook portion 13 of the plug member 10 is locked to the locking portion 23 of the socket member 20. Furthermore, a gap is formed between the plug member 10 and the socket member 20 by the first gap adjustment rib 17 provided on the plug member 10 and the second gap adjustment rib 26 and raised portion 27 provided on the socket member 20. It's getting harder. Therefore, even if the tensile force 8 shown in FIG. 5 is applied, the connected state between the plug member 10 and the socket member 20 can be stably maintained. That is, the fastener 1 of the first embodiment is strong against the above-mentioned longitudinal tensile force 8, and is particularly suitable for use in products such as pants that are susceptible to such force.

On the other hand, when removing the plug member 10 connected to the socket member 20 from the socket member 20, for example, grasp the upper front part of the pants with one hand and move the plug member 10 against the socket member 20 in the circular direction shown in FIG. Turn it up and pull it up as shown by the arc-shaped virtual line arrow 9. Thereby, the locking of the hook part 13 by the locking part 23 is released, and the plug member 10 and the socket member 20 can be easily separated.
