Description

  The present invention relates to a hook-and-loop fastener including a large number of engagement pieces such as loops and hooks, and more particularly to a hook-and-loop fastener device that can be used to freely assemble or disassemble a plurality of housings, structures, or sheet bodies.

  Conventionally, a hook-and-loop fastener provided with a plurality of engaging elements and having a member that can be attached to the back side of the object as a means for easily engaging or disassembling an object between the engaging elements. Has been used. When this hook-and-loop fastener is used outdoors or in places where dust is likely to stand, the hook-and-loop fastener is in a clean state because it is attached to another hook-and-loop fastener when using the hook-and-loop fastener, but the hook-and-loop fastener is not used. In some cases, dust or dirt or the like adheres to the fastener surface in the plurality of engaging elements, and depending on the degree of adhesion of the dust or dust, the engagement function of the surface fastener is lowered. It was necessary to remove dust or the like every time dust or the like was caught in the combined element.

  As a countermeasure against such dust accumulated in the engagement element on the fastener surface, for example, as shown in Patent Document 1, a large number of engagement elements 7 are provided on the surface of the substrate 6 to form the surface fastener 1. The sheet material 4 was polymerized on the hook-and-loop fastener 1 so that the engaging element 7 was inserted into the gap 9 in the sheet material 4 provided with the gap 9, and when the sheet material 4 was peeled from the hook-and-loop fastener 1, it adhered to the engaging element 7. There is a technique for removing lint and the like together with the sheet material 4.

  EMBODIMENT OF THE INVENTION The form for implementing the hook_and_loop | surface fastener apparatus based on this invention is demonstrated below based on an Example.

  The hook-and-loop fastener apparatus according to the first embodiment will be described with reference to FIGS. 1 to 5. The hook-and-loop fastener device of the present invention has a hook-and-loop fastener function, and is mainly used when a plurality of casings, structures, and sheet bodies are freely assembled or fixed at predetermined positions and then disassembled. The hook-and-loop fastener devices 1 and 1 'are described as being applied when the curtain 3 that is a sheet body is assembled to the inner wall 2 of the automobile at a predetermined position in the present embodiment. To do.

  As shown in FIG. 1, two hook fastener devices 1 are arranged on a vehicle interior wall 2 on a ceiling side and a floor side, which are predetermined fixed portions, by fixing portions 4 described later. Further, in the curtain 3, the hook-and-loop fastener devices 1 ′ are arranged at a predetermined fixed portion corresponding to the hook-and-loop fastener device 1 by a fixing portion 4 at a total of four locations. The hook-and-loop fastener apparatus 1 is paired with the hook-and-loop fastener apparatus 1 ′, and the curtain 3 is fixed to the vehicle inner wall 2 by being able to engage and disengage with each other. The hook-and-loop fastener devices 1 and 1 'may be arranged in a desired quantity at a predetermined position and the sheet body, and can be appropriately set according to the mode. Hereinafter, only the hook-and-loop fastener apparatus 1 will be described because the hook-and-loop fastener apparatuses 1 and 1 'have the same configuration.

  The hook-and-loop fastener device 1 has a sheet-like base portion 5 configured to be foldable by a fold portion 10, and the sheet-like base portion 5 is a first engagement surface of the present invention and is formed on the inner surface of the sheet-like base portion 5. An engagement surface 6 that is a provided surface fastener, a cover surface 7 that is a second engagement surface of the present invention and is a surface fastener that is detachable from the engagement surface 6, and a fixing means of the present invention that is predetermined. The fixing part 4 for fixing to a to-be-fixed site | part is provided.

  First, the sheet-like base 5 will be described. As shown in FIG. 2A, the sheet-like base 5 includes one first sheet-like base 5 a where the engagement surface 6 is disposed by the folding portion 10, and two second sheets where the cover surface 7 is disposed. It is divided into two sheet-like base portions 5b and 5c. More specifically, the sheet-like base portion 5 has the folded portions 10 and 10 disposed at both ends of the first sheet-like base portion 5a that is the outer periphery of the first sheet-like base portion 5a, and one end portion of the first sheet-like base portion 5a. Has a second sheet-like base portion 5b, and has a second sheet-like base portion 5c ′ at the opposite end. Thus, the sheet-like base portion 5 is brought into a non-use state of the hook-and-loop fastener function by closing the second sheet-like base portions 5b and 5c toward the engagement surface 6 of the first sheet-like base portion 5a, and the first sheet-like base portion 5a On the other hand, the hook-and-loop fastener function of the engagement surface 6 can be used by opening the second sheet-like base portions 5b and 5c outward.

  That is, the folded portions 10 and 10 with the second sheet-like base portions 5b and 5c are arranged on the outer periphery of the first sheet-like base portion 5a, and the second sheet-like base portions 5b and 5c are inspected with respect to the first sheet-like base portion 5a. It can be opened and closed.

  Therefore, since the engaging surface 6 arranged on the inner surface of the first sheet-like base 5a is surrounded by the second sheet-like bases 5b and 5c from the circumferential direction via the folding parts 10 and 10, the hook-and-loop fastener function is not used. Thus, it is possible to reliably prevent dust and the like from adhering to the fastener surface.

  Furthermore, the fixing | fixed part 4 is provided in the back surface of this 1st sheet-like base 5a. The hook-and-loop fastener device 1 is used by being fixed to a fixed portion of the vehicle inner wall 2 by a fixing portion 4 provided on the back surface of the first sheet-like base portion 5a, and the second sheet-like base portions 5b and 5c are formed in a first sheet-like shape. The base 5a can be freely opened and closed (see FIGS. 4 and 5). The hook-and-loop fastener device 1 ′ is also used by being fixed to the fixed portion of the curtain 3 with the same configuration.

  The sheet-like base 5 is composed of a single elastic sheet material, and is biased so that the first sheet-like base 5a and the second sheet-like bases 5b and 5c are flush with each other.

  In this way, the first sheet-like base portion 5a and the second sheet-like base portions 5b and 5c are biased so as to be flush with each other, thereby engaging the engagement surface 6 and the cover surface 7 together. When unraveled, the second sheet-like base portions 5b and 5c are opened in the direction of 180 degrees with respect to the engaging surface 6 through the folding portion 10, and the engaging surface 6 'of the hook-and-loop fastener device 1' is opened on the engaging surface 6. The approach becomes easier.

  More specifically, the elastic sheet material is a sheet material constituted by an elastic member such as rubber or synthetic resin, and the sheet-like base 5 is flush with the elastic restoring force of the elastic sheet material. When the engagement surface 6 and the cover surface 7 are disengaged, they can be easily unwound. Further, since the sheet-like base portion 5 is made of an elastic sheet material, the folding portion 10 is formed with the engagement surface 6 and the fold line by the elastic restoring force of the elastic sheet material when the cover surface 7 is engaged. And has a substantially semicircular arc shape extending between the first sheet-like base portion 5a and the second sheet-like base portions 5b and 5c.

  In the present embodiment, the sheet-like base 5 is made of a single elastic sheet material, but is not limited to this, for example, the first sheet-like base and the second sheet-like base in the sheet-like base. Only the folding part 10 may be made of an elastic sheet material, and the first sheet-like base part and the second sheet-like base part may be urged to be flush with each other, and at least the folding part is elastic such as an elastic sheet material. What is necessary is just to be comprised by the member which has this.

  Furthermore, one first sheet-like base portion 5a where the engagement surface 6 divided by the folding portion 10 is arranged, and two second sheet-like base portions 5b where the cover surface 7 divided by the folding portion 10 is arranged, The second sheet-like base portion is arranged so that the engagement surface 6 is not exposed to the outside when the engagement surface 6 and the cover surface 7 are engaged with each other. 5b and 5c are covered.

  According to this, when the hook-and-loop fastener function is not used, the engagement surface 6 is not exposed to the outside, so that dust or the like does not adhere to the engagement surface 6 but is erroneously engaged with other members or the like. This makes it possible to prevent the work during movement or reuse from becoming complicated.

  Moreover, the handle 13 is extended in the edge part facing the 1st sheet-like base part 5a at the 2nd sheet-like base parts 5b and 5c, respectively. This facilitates opening and closing of the second sheet-like bases 5b and 5c. Note that the position of the handle 13 is not limited to the end of the second sheet-like base 5, and may be provided on the back surface of the second sheet-like base 5.

  Next, the engagement surface 6 and the cover surface 7 will be described. The engagement surface 6 and the cover surface 7 are engaged with each other by a hook-and-loop fastener composed of male and female mixed engagement elements in which hook type and loop type engagement elements are mixed. The combination elements are formed less than the engagement elements on the first engagement surface.

  Since the engagement elements on the cover surface 7 are formed to be smaller than the engagement elements on the engagement surface 6, the engagement between the engagement surface 6 and the cover surface 7 can be lightly fixed. When releasing from the engaging surface 6, it is possible to adjust so as not to affect the fixing state between the fixing portion 4 and the fixed portion of the vehicle inner wall 2.

  The cover surface 7 may be provided anywhere on the second sheet-like bases 5b and 5c as long as it is in a position corresponding to the engagement surface 6 when the surface fastener function of the engagement surface 6 is not used. The amount of the engagement element 7 is preferably about one third of the amount of the engagement element of the engagement surface 6, and it is preferable that the engagement element is not provided in the folding part 10. Note that the engagement surface 6 and the cover surface 7 are not limited to the male / female mixed engagement element, and may be a hook type engagement element and a loop type engagement element, or one type of engagement element. It may be composed of a hook-type engaging element that can be engaged with the bracket.

  Next, the fixing unit 4 will be described. As shown in FIG. 3, the fixing portion 4 of the present embodiment provided on the substantially entire back surface of the first sheet-like base portion 5a has a predetermined thickness, and has adhesiveness and elasticity. Yes. Thereby, the hook-and-loop fastener apparatus 1 is elastically deformed according to a to-be-fixed site | part according to the elasticity of the fixing | fixed part 4, and predetermined | prescribed thickness, for example, when the to-be-fixed site | part of the vehicle inner wall 2 is uneven | corrugated or curved, adhesive Since it sticks according to the nature, it can be firmly fixed to various fixed parts.

  In addition, the position which provides the fixing | fixed part 4 in the back surface of the 1st sheet-like base part 5a may be a periphery, may be provided partially in four corners, and can be set suitably. Alternatively, the first sheet-like base portion 5a may be opened and closed by being provided on the back surface of any one of the second sheet-like base portion 5b to the second sheet-like base portion 5c '. Further, the fixing portion 4 of the present embodiment has a predetermined thickness and has adhesiveness and elasticity. However, the fixing portion 4 is not limited to this, and for example, a double-sided tape or the like is attached to the back surface of the first sheet-like base portion 5a. The fixing part may be provided simply by sticking to.

  An affixing surface 4 a for adhering the fixing part 4 to the fixed part of the vehicle inner wall 2 is covered with a protective sheet 14 for protecting the fixing part 4. The procedure for fixing the hook-and-loop fastener device 1 to the fixed portion of the vehicle interior wall 2 is as follows. First, the protective sheet 14 is peeled from the sticking surface 4a so that the fixing portion 4 can be stuck, and the back surface of the first sheet-like base portion 5a is attached to the inside of the vehicle. The hook-and-loop fastener apparatus 1 is fixed by sticking toward the fixed part of the wall 2. Therefore, the hook-and-loop fastener device 1 can be freely positioned until the protective sheet 14 is peeled from the sticking surface 4a.

  As described above, the surface fastener device 1 is configured. Next, a detailed description will be given of switching from the state in which the surface fastener function of the engagement surface 6 is not used (see FIG. 2B) to the state in which the surface fastener function of the engagement surface 6 can be used (see FIG. 2A).

  As shown in FIG. 4, when the hook-and-loop fastener function of the engagement surface 6 is not used, the ends of the second sheet-like base portions 5b and 5c overlap on the longitudinal center line A of the first sheet-like base portion 5a. The second sheet-like base portions 5b and 5c are gradually peeled from the center line A of the first sheet-like base portion 5a in the outer peripheral direction of the first sheet-like base portion 5a. Therefore, the load at the time of peeling between the engagement surface 6 and the cover surface 7 is prevented from being applied to the periphery of the contact surface between the affixing surface 4a of the fixing portion 4 and the fixed portion, and the fixing portion 4 and the vehicle inner wall Since it is possible not to affect the fixed state with the two fixed parts, the state in which the hook-and-loop fastener device 1 is firmly fixed to the fixed part is maintained.

  Further, as described above, since the engagement elements of the cover surface 7 are formed to be smaller than the engagement elements of the engagement surface 6, the engagement between the engagement surface 6 and the cover surface 7 is lightly fixed. Therefore, it can be adjusted so as not to affect the fixing state between the fixing portion 4 and the fixed portion of the vehicle inner wall 2, and the engagement surface 6 and the cover surface 7 can be easily separated. Furthermore, as described above, the sheet-like base 5 is made of a single elastic sheet material and is biased so that the first sheet-like base and the second sheet-like base are flush with each other. Thus, the engagement surface 6 and the cover surface 7 can be easily peeled off.

  Next, the manner in which the hook-and-loop fastener device 1 'installed at the fixed portion of the curtain 3 is engaged with the hook-and-loop fastener device 1 installed at the fixed portion of the vehicle inner wall 2 will be described with reference to FIG. .

  The hook-and-loop fastener devices 1 and 1 'are in a state in which the hook-and-loop fastener function of the respective engaging surfaces 6 and 6' can be used, and are engaged with each other by bringing the engaging surfaces 6 and 6 'into contact with each other. The curtain 3 is fixed to the vehicle inner wall 2. In a state where the engagement surfaces 6 and 6 'are engaged with each other, the cover surfaces 7 and 7' are also engaged with each other, and the second sheet is formed by the engagement between the cover surfaces 7 and 7 '. The movement of the shape base portions 5b and 5c is relatively restricted, and not only can it be prevented from accidentally engaging with other members and the like during use, but also the engaging force of the hook-and-loop fastener devices 1, 1 'is improved.

  As described above, in the surface fastener device of the present invention, the sheet-like base portion 5 is configured to be foldable at least by the folding portion 10, and a hook-and-loop fastener is provided on the inner surface of the first sheet-like base portion 5 a divided by the folding portion 10. The engagement surface 6 is provided, and the inner surface of the second sheet-like base portions 5b and 5c divided by the folding portion 10 is provided with a cover surface 7 having a hook-and-loop fastener that can be engaged with and disengaged from the engagement surface 6. At least one of the first sheet-like base 5a and the second sheet-like bases 5b and 5c is provided with a fixing portion 4 for fixing the sheet-like base 5 to a predetermined fixed site. As a result, the hook-and-loop fastener device is first used by being fixed to the fixed portion by the fixing portion 4 of the sheet-like base portion 5. When the hook-and-loop fastener function is not used, the second sheet-like base portions 5b and 5c are folded inward along the folding portion 10 so that the fastener surfaces of the engagement surface 6 and the cover surface 7 are engaged with each other. The function of the fastener surface can be disabled. Therefore, dust and the like can be prevented from adhering to the fastener surface when the hook-and-loop fastener function is not used, and work during movement or reuse is not complicated. Further, when the fastener surface is used, the engagement function of the used fastener surface can be resumed only by releasing the engagement between the engagement surface 6 and the cover surface 7.

  Next, it attaches to the hook_and_loop | surface fastener apparatus 11 which concerns on Example 2, and demonstrates with reference to FIG. In addition, the same structure as the said Example and the overlapping structure are abbreviate | omitted.

  As shown in FIG. 6, the sheet-like base portion 15 of the hook-and-loop fastener device 11 includes one first sheet-like base portion 15 a on which the engagement surface 16 is disposed by the folding portion 10 and eight pieces on which the cover surface 17 is disposed. And a second sheet-like base portion 15b. Further, here, a fixing portion (not shown) is provided on the back surface of the first sheet-like base portion 15a, and the hook-and-loop fastener device 11 is fixed to the fixed portion by the fixing portion.

  The first sheet-like base portion 15a has a substantially octagonal shape in plan view, and the folded portions 10 with the eight second sheet-like base portions 15b are arranged on the outer periphery of the first sheet-like base portion 15a. . Thus, the second sheet-like base portion 15b can be opened and closed radially with respect to the center of the first sheet-like base portion 15a.

  Therefore, since the engaging surface 6 disposed on the first sheet-like base portion 15a is surrounded by the second sheet-like base portion 15b via the folding portion 10 from the circumferential direction, dust on the fastener surface is not used when the hook-and-loop fastener function is not used. It is possible to reliably prevent such adhesion.

  More specifically, since the second sheet-like base portion 15b can be opened and closed radially with respect to the center of the first sheet-like base portion 15a, the shape of one second sheet-like base portion 15b is the first sheet-like base portion 15a. It forms a substantially triangular shape that expands in the circumferential direction from the center. Therefore, when the cover surface 17 is peeled from the engagement surface 16, the engagement area between the engagement surface 6 and the cover surface 7 is reduced, and the load applied to the fixing portion during the separation is dispersed. It is possible to prevent the fixed state with the fixed site from being affected. In particular, since the second sheet-like base portion 15b divided from the center of the first sheet-like base portion 15a is opened outward, it does not affect the fixed state of the outer periphery between the fixing portion and the fixed portion. Can be.

  Next, it attaches to the hook_and_loop | surface fastener apparatus 21 which concerns on Example 3, and demonstrates with reference to FIG. 7 and FIG. In addition, the same structure as the said Example and the overlapping structure are abbreviate | omitted.

  FIG. 7 shows means for strongly installing the hook-and-loop fastener device 21 on a fixed part such as a wall at a predetermined position (not shown). The 1st sheet-like base 25a of the sheet-like base 25 in a present Example has the stabilization member 22 which is a metal flat plate inside, and the 1st sheet-like base 25a and the stabilization member 22 have the sheet-like base 25. Two through-holes 20 penetrating in the thickness direction are formed vertically in plan view. The through-hole 20 is provided at two locations in the upper and lower sides in the plan view of the first sheet-like base portion 25a and the stabilizing member 22, but 1 is provided at the periphery of the engaging surface 26 or the central portion of the engaging surface 26, etc. A location or a plurality of locations may be provided.

  After the hook-and-loop fastener device 21 is positioned at a predetermined position, the screw 23 or the like is inserted into the through-hole 20 and tightened toward the predetermined position to be firmly held between the screw 23 and the predetermined position. Installed.

  Thus, for example, even if the sheet-like base 25 is formed of a flexible member such as an elastic sheet material or cloth as in the above-described embodiment, the stability member 22 built in the first sheet-like base 25a is used. Since the first sheet-like base 25a maintains the shape of the stabilizing member 22, the engaging surface 26 is installed at a predetermined position without being bent. Further, since the through hole 20 is provided, the screw 23 can be easily fastened. When a heavy member is attached to the hook-and-loop fastener device 21, the hook-and-loop fastener device 21 is placed at a predetermined position with the screw 23. By being fastened, a heavy member can be strongly supported.

  Further, as shown in FIG. 8, the through hole 20 is formed so as to penetrate in the thickness direction of the sheet-like base portion 25, and is slightly larger than the tap portion of the screw 23 on the engagement surface 26 side of the through hole 20. The formed groove portion 24 is drilled.

  When the hook-and-loop fastener device 21 is installed at a predetermined position, the screw 23 is inserted into the through hole 20 so that the tap portion of the screw 23 is buried in the groove 24. Accordingly, the screw 23 does not protrude on the engagement surface 6 when the engagement surface 26 is in use, and the engagement function of the engagement surface 26 can be prevented from being lowered.

  In this embodiment, the stabilizing member 22 is built in the first sheet-like base portion 25a. However, the surface fastener device 21 and the stabilizing member 22 may be integrated, or the stabilizing member 22 may be integrated. The material is not limited to metal, and may be any material that is more rigid than the first sheet-like base 25a such as wood or plastic material.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the hook-and-loop fastener devices to be paired are engaged with each other, but a member that can be engaged with the engaging surface may be directly attached.

  The first sheet-like base portion and the second sheet-like base portion are not limited to the above-described embodiments, and may be appropriately set to a desired shape and quantity. In a state where the cover surface of the two-sheet base is engaged, it is preferable that the engagement surface is not exposed to the outside.
