Description

  The present invention provides a compact surface that can be securely and easily aligned with the sensation of a fingertip at an overlapped portion attached to two base materials such as cloths of clothes and the like. The present invention relates to a fastener, an engagement tool comprising a concave engagement piece provided with a surface fastener portion and a cut portion on a plastic substrate, and a convex engagement piece provided with a surface fastener portion and a projection on the plastic substrate, and It relates to a manufacturing method.

  As a conventional means for joining at the overlapping portion of two base materials, there is a normal button system composed of a button and a button hole as an easily removable means. This method is said to have been developed in England in the middle of the 18th century. There is a relatively loose button string system that engages a button-like protrusion with a narrow string somewhat earlier than that. This is a technique that was applied to samurai costumes in Japan in the early 18th century. This was mainly used for the longitudinal engagement with heavy loads because the connection was loose.

  After these coupling means were developed, ultra-small metal snap hooks were put into practical use. However, there was difficulty in positioning and it was not popular. Since then, surface fasteners have been developed up to the 20th century, and have been used under the conditions that can be used by fixing a slightly larger size to two substrates with relatively rough positioning.

  In Japan, as a coupling means developed in recent years, there is a “Kohaze” method, which is a hooking method using a combination of a metal nail shape piece and a thick thread. This is currently only used to secure the buttocks of the tabi. This limited use is due to the difficulty of work and uncertain positioning. Specifically, in the overlapped portion of the tabi, the heel part fabric is fixed in such a way that a small piece of metal sewed on the upper fabric end is held in place on the lower fabric end, but both are small. It is a member, it is difficult to confirm the position by blind touch, this overlap part must be pressed sufficiently, and even if the engagement between both is not tight, there is a possibility that it will come off during use There are some.

  A fastener that has the most room for development is a hook-and-loop fastener. Although this material is unsatisfactory, it has a track record of being attached to clothes. One of the scenes in which this hook-and-loop fastener is used is the engagement of a short moving distance between hook-and-loop fasteners and the upper part of the chest where uncertainty of position determination does not become apparent. It is used where the displacement of engagement is not noticeable. These cases are relatively small pieces. Another scene is the engagement of the lid of the bag that opens widely, the pillow cover, etc., and even if there is a shift in this engagement, it is not so noticeable. The hook-and-loop fastener that is fixed to the overlapping portion of the two base materials is often large in size, with one side being several centimeters or more, even when one hook-and-loop fastener is small.

  There is a situation in which it is difficult to use a hook-and-loop fastener in a clothing or the like where the feeling when worn is important and the appearance is worrisome, causing a displacement of the engagement. In addition, there has been a problem of an annoying sound of merriness at the time of peeling, which has existed as a problem when this hook-and-loop fastener is used for clothes and the like. However, this problem has been improved by manufacturers and released as a sound-reducing surface fastener, which has been resolved. The development of a simple engagement technique by pressing this new material has attracted attention again.

  The only method disclosed in U.S. Patents is to engage the bases with hook-and-loop fasteners after positioning. According to this method, the position of the tip is determined using the relationship between the insertion hole provided at the end of the belt-like substrate and the insertion projection, and then the hook-and-loop fastener attached to the adjacent portion is pressed to detach the substrates. Can be easily fixed. This method has problems in that it is an invention aiming at the engagement between the substrates and that it is difficult to insert and fix the tips of the substrates. In the disclosed method, it is necessary to complete the insertion and fixation while visually confirming the positional relationship between the hole and the protrusion. Looking at the shape of the disclosed holes and protrusions, a semicircular portion is provided in the center of the groove-shaped hole, and a part of the groove is widened. This shape has no effect of facilitating the insertion and fixing of the bent projections. It is judged that it is for facilitating removal of a thin groove in a punching process with ruled lines.

After the present invention, there has not been a universal design engagement means that combines the certainty of connection, the ease of operation, and the ease of positioning in the world.
A universal design that has become a global trend in recent years, but wants to make it easier to combine the placket of clothes for people with disabilities in the fingertips as the number of elderly people increases (including people with disabilities including the visually impaired) Demands arise. Various developments have been made based on this requirement.
In such a stagnation of technical development, attention has been paid to a zipper that is expensive in processing cost. However, it has been difficult to insert the chuck fixing portion at the lower end portion of the placket, and has not led to a fundamental solution. Recently, news of the developed product was released, which was released in September 2010 as a cardigan fitted with new clothing fastening means from Aeon. Although this is a conventional button system, the buttonholes are arranged obliquely to improve the fastening workability. Thus, there is a demand for the development of universal design coupling means.

  US Pat. No. 3,873,051

The present invention has been made to solve the problems of the prior art as described above, and reliably superposes the base material where the positional relationship cannot be accurately confirmed visually such as a placket of clothes, and An object of the present invention is to provide a small hook-and-loop fastener with a position fixing function by fitting that can be easily performed. Specifically, a surface fastener is fastened as an engaging means to a small concave locking piece punched out of a plastic thin board and a convex locking piece, and a hole or protrusion fitting means is separately provided in the vicinity of this. It is formed so that the position can be determined by insertion by rough blind touch. Provided is a small engagement tool with a hook-and-loop fastener that can accurately and easily attach and detach two substrates by pressing both locking pieces in parallel while maintaining this mating state, and a method for manufacturing the same. It is.
Aging societies are advancing in developed countries, including Japan, and emerging countries, and in Japan, the proportion of elderly people over the age of 65 has exceeded 23%. In such a society, people who have difficulty in fine-fingered fingertips, and clothing used by people with disabilities, such as the visually impaired, can use a cheap and simple operation instead of buttons and zippers to set the base at the correct position. There is an urgent need to develop hook-and-loop fastener applications that allow engagement of materials. There is a social need especially in the field of nursing care.

  As of 2010, attaching a hook-and-loop fastener to a garment is being performed at homes and elderly care facilities. A pair of hook-and-loop fasteners that have been punched into a round shape with a diameter of 22 mm is set and sold as a “round magic”. When this is attached to clothes, the position confirmation of both hook-and-loop fasteners is insufficient for fingertip confirmation. In general, a decorative button is attached on the outer surface of the clothes as a mark so that the attachment position of the soft hook-and-loop fastener can be confirmed with a fingertip.

The present invention solves the above-described problems, and is a surface engaging tool with an engagement position determination function.
Here, the case where a hook-and-loop fastener is used as the engaging means will be mainly described. The means of the U.S. patent disclosed as a technique relating to the alignment of the surface engaging tool is accurate as in the conventional button type when used for clothes, as mentioned above. The position confirmation by visual observation is a prerequisite. In the case of clothes, the operation is performed directly under the eyes, and it is difficult to accurately confirm this positional relationship. In addition, there is a restriction that drilling in the substrate is practically impossible.
By using the surface engagement tool of the following invention content, it is possible to engage by a blind touch at an accurate overlapping position while pressing two substrates with one hand.

The invention according to claim 1 is a convex locking piece that is used by being fixed to one of the overlapping portions of two base materials, and has a convex portion that rises from the base material and a convex side surface engaging means. The engaging piece and the receiving portion that engages with the protruding portion and the convex side engaging means of the convex engaging piece are engaged with the convex engaging piece at the overlapping portion of the base material. And a concave engaging piece having a concave side surface engaging means. The present invention relates to a surface engaging tool with a position determining function.

  According to a second aspect of the present invention, in the state in which the protruding portion of the convex locking piece and the receiving portion of the concave locking piece are engaged, the convex side surface engagement in the convex locking piece 2. The position determination according to claim 1, wherein an arrangement order of the means and the protrusion matches an arrangement order of the concave side surface engaging means and the receiving portion in the concave locking piece. The present invention relates to a surface engaging tool with a function.

  The invention according to claim 3 is the surface with a position determination function according to claim 1 or 2, wherein the protrusion of the convex locking piece is formed in a hook shape that catches the receiving portion. The present invention relates to an engagement tool.

The invention according to claim 4 is characterized in that the protrusion is provided on the convex substrate and the receiving part is provided on the concave substrate. The present invention relates to a surface engaging tool with a definite function.

  The invention according to claim 5 is characterized in that the protruding portion of the convex locking piece is provided so as to rise from 15 to 150 degrees from the convex substrate surface of the convex locking piece. It is related with the surface engaging tool with a position determination function of Claim 4.

  The invention according to claim 6 is characterized in that the protruding portion of the convex locking piece is provided so as to bend and rise from the convex substrate surface of the convex locking piece. Or the surface engaging tool with a position determination function of any one of 5.

The present invention is configured using two types of locking pieces. One is a concave locking piece (1), and a surface fastener (2), which is a representative of the surface engaging means, is fixed to the plastic substrate (5), and the position is automatically determined in the vicinity of the surface fastener. It forms in the concave-shaped latching piece which provided the notch part (3) as a receiving part of the shape which can be formed. This notch part consists of an upper edge and a lower edge, and can be made into arbitrary shapes. In the embodiment of the present invention, the upper edge of the cut hole is represented by a curve, and the lower edge (4) is represented by a straight line. The lower edge of the cut hole functions as a bar for preventing disengagement during the engaging operation.
The other locking piece is a convex locking piece (6), and this convex locking piece used opposite to the concave locking piece is a plastic hook that has a function of engaging with the hook-and-loop fastener. It is composed of a convex locking piece provided with projections (7) of various shapes that are fixed to the substrate and inserted into the notch portion as the receiving portion in a portion adjacent to the substrate and automatically fitted.

The surface engaging tool with a position determining function configured by using two types of locking pieces is inserted into the notched hole portion and further brought into contact with the peripheral edge of the hole portion, and then one locking piece. Is rotated and moved to press the surface fasteners to reach engagement. Therefore, the axial direction of the arrangement of the surface engaging means and the protrusion in the convex locking piece and the axial direction of the arrangement of the surface engaging means and the receiving portion in the concave locking piece are matched. Is a prerequisite for smooth rotation.
In order to function effectively in the area used by the hook-and-loop fastener, it is designed to engage with each other without deviation. Incidentally, one or more surface fasteners can be arbitrarily used on the substrate surface regardless of the number of protrusions.

These concave locking pieces and convex locking pieces are superposed and fixed to the ends of the two base materials to be engaged with each other, and the base materials in the expanded state are inserted at rough mating portions. By the automatic position determination according to the above, the engagement that does not cause a shift by the subsequent pressing is completed.
This fitting is performed with the protruding part formed on the plastic substrate and the notch part formed on the plastic substrate, but the protruding part is easy to fit and can be surely prevented from coming off during the pressing operation. Are provided in a state of rising from a flat substrate surface.

  Hereinafter, a typical embodiment of a small surface fastener with a position determining function according to the present invention will be described in detail with reference to the drawings. The hook-and-loop fastener according to the present invention is fixed to a plastic substrate with a double-sided adhesive tape or the like, and a concave locking piece in which a notch hole is formed in the vicinity thereof, and a protruding portion in a standing state that is used facing the locking piece Each of the convex locking pieces provided with is shown as a set. FIG. 1 to FIG. 4 show plan views of four types of surface engaging tools as No. 1, No. 2, No. 3, and No. 4. The notches used here include bay-shaped holes and closed hole shapes.

The right figure in FIG. 1 is a convex locking piece having one protrusion that rises and has an angle. The figure on the left is a concave locking piece that houses a protrusion protruding from the flat plate and has one notch to be fitted.
FIG. 2 of the second is an engaging tool similar to that of the first embodiment, which is a type in which the protrusion is provided on the opposite side.
3 of FIG. 3 is an engaging tool in which the protruding portion of the rising edge of the substrate is formed in a U shape, and the lower edge portion of the hole to be fitted is formed into a thin bar shape so that the protruding portion can be easily rotated. Type.
FIG. 4 of No. 4 is an engaging tool in which the protruding portion of the rising edge of the substrate is formed in a U shape, and is a type having two protruding portions. There are also two holes to be fitted, and the lower edge is a thin bar.

  FIG. 5 to FIG. 8 schematically show the fitting operation of the above four types of engaging tools in cross-sectional views of both locking pieces. In the relationship between the protruding protrusion and the hole, the insertion method of the protrusion and the direction of rotation and pressing of the locking piece are the points. This rotation / pressing direction is related to which surface of the substrate the surface fastener is attached to.

In FIG. 5, both locking pieces are attached to the end portions of the two base materials, the hook-and-loop fastener portion is gripped with a finger, the raised protrusion is moved in the vicinity of the hole portion, and insertion and fitting are confirmed with a fingertip sense. Thereafter, the two holding pieces are pressed and overlapped while releasing the gripping finger. Actually press the hook and loop part strongly.
In this fitting, the protruding portion is brought into contact with the lower edge (4) of the hole portion and brought into contact therewith, and the fitting state is confirmed by sensing the contact between the plastic pieces.

A detailed configuration of the locking piece will be described. The present invention has been accomplished for the purpose of ensuring that the engaging pieces are engaged with each other more reliably and with an easy operation. The linear shape in which the cross section of the protrusion shown in FIGS. 1 and 2 is L-shaped is a typical shape in the case where the protrusion is provided in a bowl shape in order to ensure engagement. The raised protrusion formed on the convex locking piece can be bent by press-molding so as to protrude from the flat plate using a jig while heat-treating the portion of the substrate formed by punching.
By adding a device to make a cut (8) at the base of the bent part formed on this protrusion, a ruled line effect can be obtained, and even a small part can be angled relatively easily by light hot press molding. The shape can be changed. A jig having a complicated two-stage bending mechanism is used for the U-shape or U-shape.

As shown in FIGS. 3 and 4, the U-shaped protrusion including the rounded portion, or the intermediate “U-shaped” or “U-shaped” protrusion with the above-mentioned L-shaped protrusion is the engagement of the locking piece. And make the rotation more reliable. These protrusion shapes are formed so that the entire protrusion is bent to have a uniform plane with respect to the substrate surface.
One or a plurality of these protrusions may be provided. The number of holes corresponding to this may be the number corresponding to this, or the number of communication holes may be small. The protrusion may be a thick rod-shaped protrusion or a plate having a predetermined width. The former has a shape suitable for injection molding in which the thickness can be adjusted. An example of a flexible curved shape by molding is shown in FIG. By adopting this molding method, the base of the projection can rise linearly at an angle, and the combined complex shape of claims 5 and 6 can be provided with a small radius at the tip.

Further, the setting of the bending angle of the protrusion varies depending on the degree of fitting required. This angle is set to 15 degrees to 150 degrees as an angle on the side where the convex locking piece rises from the substrate surface and engages. Preferably it is in the range of 45 degrees to 120 degrees.
In the case of a locking piece that tends to warp as shown in FIG. 2, even if the protrusion has an acute angle of 30 to 45 degrees with respect to the lower edge of the notch hole portion to be fitted, the pressing pieces warp against each other. When used, the fit is actually easy to do.

  The lower edge part of the notch hole as a receiving part of a projection part is demonstrated. The protrusions in FIGS. 1 and 2 are formed in the vicinity of the central portion of the substrate, and the insertion and fitting directions of the protrusions with respect to the holes are the same as the pressing direction of the hook-and-loop fastener. And the fixation of the hook-and-loop fastener to the substrate is facing from the beginning. Therefore, the angle of rotation accompanying the movement of the latter convex locking piece to be pressed is an angle at which the hook-and-loop fastener portion of the engagement piece is gripped by the fingertip during fitting and opened for insertion, and is slightly It is.

On the other hand, in the fitting shown in FIGS. 3 and 4, the protruding portion at the edge of the substrate that has stood up is inserted into the hole, and is brought into engagement with the peripheral edge of the hole. Must rotate. The surface fasteners can be pressed / engaged by this slightly large reversal rotation. This is because the hook-and-loop fasteners do not face each other at the time of fitting as shown in FIGS.
Further, the protrusion shape in this case is curved, and in order to smoothly perform the reversal rotation, the lower edge portion of the hole portion to which the protrusion portion hits must have a narrow thin bar shape. If it is about 2 mm or 3 mm, the thin plate is finished by punching. And this curved projection part needs to be formed so that the space | interval more than the width | variety of a thin bar may be maintained.
In order to smoothly rotate the convex locking piece, it is preferable to make the fine bar round rather than square. Although the diameter is 1 to 4 mm, a diameter of 3 to 4 mm is suitable in consideration of strength such as washing resistance of the entire locking piece. In the case of this bar shape, the entire locking pieces are integrally formed by injection molding.

By making the protrusion stand up from the substrate surface as described above, even when fitting using a slippery plastic material, the protrusion is made difficult to come off during confirmation of the fitting position and rotation / press operation. be able to.
As a design technique for assisting the difficulty in detachment, there is a method in which the edge of the substrate related to the fitting is rough and jagged. In the case of a locking piece manufactured by punching, a corrugated blade with a corrugated tip is used as the punching die.

Next, the material and size of the locking piece will be described. Since the entire locking piece as shown in FIG. 1 is involved in improving the operability of the fitting, a polypropylene thin plate made of a plastic material is excellent in terms of cost performance. A sheet having a thickness of 0.5 mm or 0.75 mm made of the same material is suitable in terms of sewing and punching workability.
In the case of the shape of FIG. 1, the concave locking piece is about 40 mm × 70 mm in the 1-hole method, and the convex locking piece is about 40 mm × 90 mm, and the concave locking piece is 75 mm in the 2-hole design. × 70 mm, the convex locking piece is about 75 mm × 90 mm.

  The punching shape of the rising protrusion is shown as a trapezoid in FIG. 1, but it may be a semicircle. A shape in which the tip is narrower than the base is suitable for easy insertion into the notch. In the case of a trapezoidal shape, the base dimension is in the vicinity of 20 mm to 25 mm, and the rising height dimension is about 10 mm.

  In FIG. 1, the shape is assumed to be stamped and manufactured. However, in the case of injection molding, protrusions can be arbitrarily provided in various shapes in a state where no hole is formed in a flat plate as a substrate.

Next, the fitting operation of both locking pieces will be described. The space on the opposite side of the hook and loop fastener of the convex locking piece that is longer than the concave locking piece is used to press the concave locking piece by deflecting the space portion of the convex locking piece with a fingertip. If it is in this state, it will become easy to perform fitting of a projection part and a notch hole. This is an effect that the distance between the engaging surface fasteners can be taken. And it becomes easy to insert the tip of a solid projection.
In order to increase this effect, the distance between the hook-and-loop fastener and the protrusion and the distance between the notch and the cutout are set to 15 mm to 30 mm, respectively. As a result, the state in which the hook-and-loop fastener of the convex locking piece is gripped by the fingertip can be easily maintained. This is effective in engaging in a cramped place in the front part of the neck under the clothes.

  FIG. 3 shows a protrusion of a type in which the protrusion that rises three-dimensionally from the substrate of the convex locking piece and has a curved surface is formed. It is a curved surface shape for making it more difficult to come off when entering the pressing operation between the hook-and-loop fasteners. This includes a so-called hook shape with a turn portion provided at the tip of the protrusion. The illustration of the notch part shape corresponding to this and the overall shape of the concave locking piece is omitted. This curved surface shape can be designed into an arbitrary shape in consideration of the required catching state and other conditions.

FIG. 4 is an engagement work process diagram as a fastener when both locking pieces are actually attached to the base material. This figure is a diagram schematically showing how the locking pieces fit together at the overlapping portion of the base material ends such as clothing, by simplifying the shape of the locking pieces. Therefore, the protruding portion in FIG. 4 is not shown as the protruding portion of the present invention.
This figure shows a system in which the protrusion of the convex locking piece is fitted into the hole of the concave locking piece held on the body side by gripping the surface fastener side of the convex locking piece. On the other hand, a method of gripping the hook-and-loop fastener side of the concave locking piece and entering a fitting operation with respect to the protruding portion of the convex locking piece can also be adopted (not shown).
