Description

  The present invention relates to a structure of a curtain hook for suspending a curtain on a curtain rail.

  Generally, a curtain is hooked on a curtain rail via a curtain hook. The curtain hook is slidably attached to the curtain rail. Accordingly, the curtain is suspended from the curtain rail and is slid along the curtain rail in this state.

  FIG. 11 is a perspective view showing the structure of a conventional curtain hook 1.

  As shown in the figure, the curtain hook 1 includes an engagement portion 2 and a curtain support portion 3. The curtain support portion 3 supports the curtain, and the engagement portion 2 is engaged with the curtain rail. Accordingly, the curtain is suspended from the curtain rail via the curtain support portion 3.

  The curtain support part 3 has a clip structure as shown in FIG. 1 (see, for example, Patent Document 1 to Patent Document 10). The curtain is supported by the curtain hook 1 by sandwiching a curtain liner (also referred to as “interlining”) provided on the curtain by the curtain support portion 3 having such a structure. .

JP-A-8-317851 JP 2007-130497 A JP 2006-346057 A JP 2006-101977 A JP 2006-68490 A JP 2006-68323 A JP 2005-329032 A JP 2005-296329 A JP 2004-229949 A JP 2004-187726 A

  Generally, the curtain liner has a pocket into which the curtain support portion 3 is inserted. The curtain support part 3 has a main body part 4 and a sandwiching piece 5, and the sandwiching piece 5 is inserted into a pocket provided in the curtain liner. Thereby, the curtain support part 3 clamps the curtain liner, and as a result, the curtain is supported by the curtain hook 1.

  Incidentally, as described above, since the curtain hook 1 supports the curtain, there is a demand that the curtain hook 1 must be prevented from easily falling off the curtain. That is, the curtain hook 1 is required to be easy to insert into the curtain and to be difficult to remove from the curtain. The curtain hook 1 may be sold as an accessory part of the curtain, but in such a case, the demand is still stronger.

  Moreover, the curtain may be shipped in a state where the curtain hook 1 is attached to a curtain as a product. In such a case, even if the curtain hook 1 falls off the curtain, there is substantially no problem, but the situation that the curtain hook 1 is scattered randomly when the user opens the product is not preferable. If the hook 1 can reliably engage with the curtain, the quality of the curtain as a product is improved.

  Furthermore, the curtain liner has a plurality of pockets, which are arranged side by side. The clamping piece 5 of the curtain support part 3 is inserted into each pocket. When the sandwiching pieces 5 are inserted into the pockets, irregularities are continuously formed along the curtain liner. For this reason, there is a problem that the appearance of the curtain is lowered and the operation of engaging the curtain with the curtain rail becomes difficult.

  In addition, in a state where the sandwiching piece 5 of the curtain support portion 3 is inserted into the curtain liner, the curtain hook 1 is easy to rotate around the axial direction of the sandwiching piece 5 (the direction indicated by reference numeral N in the figure). , May become unstable. Therefore, it may be difficult to hook the curtain on the curtain rail while the curtain hook 1 is attached to the curtain.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a curtain hook that is reliably and stably fixed to a curtain liner and that does not cause large irregularities in the curtain liner even when fixed.

  (1) A curtain hook according to the present invention is a curtain hook for suspending a curtain in which a hanging pocket is formed by attaching a curtain liner to a curtain body on a curtain rail. The curtain hook includes a main body having a pair of shaft portions and a hook. Each of the pair of shaft portions has a proximal end and a distal end. The shaft portions are arranged to face each other so that the base ends are continuous and the tips are in contact with each other in the front-rear direction, and extend in the up-down direction (that is, the direction orthogonal to the front-rear direction). One shaft portion is inserted into the hanging pocket upward from the front end side so that the pair of shaft portions cooperate to sandwich the curtain liner. The hook is provided on the base portion and the base portion that are fitted to the other shaft portion in a slidable state from the distal end side to the proximal end side of the other shaft portion, and by engaging the curtain rail, the main body and It has a key part for hanging the curtain. The hook is attached to the other shaft portion via a slide mechanism, and the slide mechanism allows the hook to slide from the distal end side to the proximal end side of the other shaft portion, and Restricts sliding from the proximal side to the distal side.

  The slide mechanism is formed on the other shaft portion and includes a slide base including an engagement groove extending in the up-down direction, and a slider including an engagement protrusion formed in the base portion and fitted into the engagement groove. A plurality of check pieces juxtaposed on the slide base along the vertical direction and projecting symmetrically in the horizontal direction perpendicular to both the vertical direction and the front-rear direction, and provided on the left and right edges of the slider. And a pair of locking claws that can be engaged with the check piece. The check piece includes an inclined surface that gradually expands in the left-right direction from the distal end side to the proximal end side of the other shaft portion, and a contact surface that extends along the left-right direction continuously to the inclined surface. . The pair of locking claws can be elastically deformed so that they can come close to each other and abut against the abutting surface and can be separated from each other along the inclined surface when the slider slides relative to the slide base. Is formed.

  The facing surface of the one shaft portion that faces the other shaft portion is smoothly bulged toward the other shaft portion. The tip portion of the one shaft portion is formed in a bowl shape. The opposite surface of the one shaft portion opposite to the facing surface is formed as a flat surface.

  According to this configuration, the hook is attached to the other shaft portion of the main body. Specifically, the base portion of the hook is fitted into the other shaft portion from the distal end side of the other shaft portion. At this time, since the slide mechanism is provided, the hook can slide only from the distal end side to the proximal end side of the other shaft portion (that is, only downward in the vertical direction). When one shaft portion is inserted upward in the vertical direction into the hanging pocket of the curtain, the curtain body is sandwiched between the pair of shaft portions, and the curtain is hooked on the hook so as to be supported from below. The curtain is suspended from the curtain rail by engaging the key portion of the hook with the curtain rail.

  Since the opposing surface of one shaft portion bulges smoothly toward the other shaft portion, and the tip end portion of one shaft portion is formed in a hook shape, the one shaft portion is used for the suspension. Easily inserted into the pocket. In addition, the pair of shafts can securely hold the curtain liner. Furthermore, the one shaft portion once inserted into the hanging pocket does not easily come off. In addition, since the surface opposite to the facing surface of one shaft portion is a flat surface, the one shaft portion is prevented from rolling unstablely in the hanging pocket, and a curtain liner is provided. Large irregularities are not formed on the formed portion.

  Since the hook can slide in the vertical direction with respect to the main body, the height of one shaft portion with respect to the curtain rail is adjusted in accordance with the length of the curtain. That is, even if the curtain height changes, the curtain is always arranged at a constant height. In addition, when the hook base is inserted into the other shaft portion of the main body, the engagement groove provided on the slide base of the other shaft portion and the engagement protrusion provided on the slider of the base portion are fitted together. The hook is attached to the main body without rattling. In addition, since the hook is restricted from sliding upward and downward with respect to the main body, when the curtain is hooked on the other shaft portion, the other shaft portion is relatively vertically directed downward by the weight of the curtain. Movement is restricted. That is, the curtain does not shift downward. Such a slide regulation is realized because the base is slid only in the vertical direction downward with respect to the other shaft part by the contact of the locking claw of the slider with the check piece of the slide base, and therefore, There is an advantage that the structure for realizing the slide regulation is very simple. In addition, when the base portion moves downward in the vertical direction, the locking claw is elastically deformed and the contact with the contact surface is easily released, so that the operator intentionally slides the hook. It is very simple.

  (2) The tip portion of the one shaft portion includes a projecting surface that projects symmetrically in the left-right direction from the tip of the one shaft portion, and a horizontal plane that continues to the projecting surface and extends in the left-right direction, The overhanging surface is preferably curved in the left-right direction to form a concave surface.

  According to this configuration, one of the shaft portions can be more easily inserted into the hanging pocket, and is less likely to come off.

  According to the present invention, the operation of inserting the curtain hook into the curtain liner is extremely easy, and the curtain liner is securely clamped and the curtain is stably suspended. Moreover, there is an advantage that the curtain liner does not have large irregularities and the appearance of the curtain is improved.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

1. <General configuration and features>

  FIG. 1 is a perspective view of a curtain hook 30 according to an embodiment of the present invention.

  Generally, a curtain has a curtain body and a curtain liner formed in a strip shape. The curtain liner is sewed over the upper edge of the curtain body. A curtain pocket is superimposed on the curtain body to form a hanging pocket for hanging the curtain. The curtain is hooked on the curtain rail via the curtain hook 30 (see FIG. 1) according to the present embodiment. As will be described in detail later, the curtain hook 30 is inserted into the suspension pocket and engaged with the curtain rail, whereby the curtain is slidably suspended on the curtain rail.

  The curtain hook 30 includes a main body 31 inserted into the hanging pocket and a hook 32 that engages with the curtain rail. The hook 32 is attached to the main body 31 via a slide mechanism 33 described later. The features of the curtain hook 30 according to the present embodiment are as follows: (1) The shape of the main body 31 is devised so that the main body 31 is easily inserted into the hanging pocket and is not easily removed; (2) the main body 31 Is devised so that it can be stably placed in the state of being inserted into the hanging pocket, and (3) Curtain height adjustment is very simple and easy by the slide mechanism 33. It is a point that has come to be performed.

2. <Main body configuration>

  FIG. 2 is a perspective view of the main body 31. 3 to 6 are respectively a III-arrow view (side view), an IV-arrow view (plan view), a V-arrow view (rear view), and a VI-arrow view (bottom view) in FIG. ).

  The main body 31 is made of resin. As shown in FIG. 2, the main body 31 includes a front shaft portion 34 (the other shaft portion) and a rear shaft portion 35 (one shaft portion). The front shaft portion 34 and the rear shaft portion 35 are each formed in an elongated rod shape. The front shaft portion 34 and the rear shaft portion 35 are integrally formed, and the base end 36 of the front shaft portion 34 and the base end 37 of the rear shaft portion 35 are continuous. The front shaft portion 34 and the rear shaft portion 35 are disposed so as to face each other in the front-rear direction. The front end 38 of the front shaft portion 34 and the front end 39 of the rear shaft portion 35 are in contact with each other in the front-rear direction. In this specification, the “front-rear direction” is a direction in which the front shaft portion 34 and the rear shaft portion 35 face each other (the direction of the arrow 40 in FIG. 3). Therefore, the front shaft portion 34 is disposed on the front side in the front-rear direction, and the rear shaft portion 35 is disposed on the rear side in the front-rear direction.

  As shown in FIGS. 2 to 4, the front shaft portion 34 extends in the vertical direction. In this specification, the “vertical direction” is a direction orthogonal to the front-rear direction (the direction of the arrow 41 in FIG. 3). As shown in FIGS. 2 and 6, the front shaft portion 34 includes a substrate 42 and a slide base 43. In the present embodiment, the substrate 42 and the slide base 43 are integrally formed. The slide base 43 includes a pair of engagement grooves 44 and 45. The engagement grooves 44 and 45 are provided symmetrically on the right and left sides of the slide base 43, and extend in the vertical direction along the slide base 43. The engaging grooves 44 and 45 extend to the upper end and the lower end of the slide base 43.

  As shown in FIGS. 2 and 4, the slide base 43 includes a front plate 46. The front plate 46 is a flat member formed on the front side of the slide base 43 as a result of the engagement grooves 44 and 45 being provided in the slide base 43. The front plate 46 includes a plurality of check pieces 47. These check pieces 47 are juxtaposed along the vertical direction (the direction of the arrow 41 in FIG. 3). Each check piece 47 is provided in a pair so as to project symmetrically in the left-right direction. In this specification, the “left-right direction” is a direction orthogonal to both the front-rear direction and the up-down direction, and is the direction of the arrow 48 in FIG. In this embodiment, 13 pairs of check pieces 47 (26 check pieces 47) are provided along the vertical direction.

  As shown in FIGS. 2 and 4, each check piece 47 includes an inclined surface 49 and a contact surface 50. Each inclined surface 49 projects leftward and rightward from the left and right side surfaces of the front plate 46. The inclined surface 49 protruding leftward is inclined so as to gradually expand in the leftward direction from the distal end 38 side of the front shaft portion 34 toward the proximal end 36 side. Further, the inclined surface 49 projecting in the right direction is inclined so as to gradually expand in the right direction from the distal end 38 side of the front shaft portion 34 toward the proximal end 36 side. Further, the contact surface 50 is continuous with each inclined surface 49. Specifically, each contact surface 50 is continuous with the lower edge of each inclined surface 49 (the edge on the base end 36 side of the front shaft portion 34) and extends straight in the left-right direction (the direction of the arrow 48). . In short, the front plate 46 is formed in a “bamboo shoot” shape projecting left and right.

  As shown in FIGS. 2, 3, and 5, the rear shaft portion 35 is disposed behind the front shaft portion 34 and extends in the vertical direction. The rear shaft portion 35 is formed in a substantially L shape (see FIG. 3). As described above, the base end 37 is continuous with the base end 36 of the front shaft portion 34, and the tip 39 is the front shaft portion 34. It is in contact with the tip 38. Since the main body 31 is made of resin, the rear shaft portion 35 can be elastically deformed along the front-rear direction (the direction of the arrow 40 in FIG. 3). The rear shaft portion 35 is inserted into the hanging pocket of the curtain from the tip 39 side. Accordingly, the rear shaft portion 35 can sandwich the curtain liner together with the front shaft portion 34. That is, the main body 31 constitutes a clip that holds the curtain liner.

  FIG. 7 is an enlarged perspective view of a main part of the rear shaft portion 35.

  As shown in FIGS. 2, 3, and 7, the facing surface 51 of the rear shaft portion 35 is formed in a smooth curved surface, and the back surface 52 of the rear shaft portion 35 is formed in a flat surface. Here, the facing surface 51 is a surface facing the substrate 42 of the front shaft portion 34. The back surface 52 is a surface opposite to the facing surface 51 opposite to the back surface, that is, the rear surface of the rear shaft portion 35. The facing surface 51 may be formed in an arcuate curved surface. Moreover, the top part (namely, part which contact | abuts the front axial part 34) of this opposing surface 51 may be formed in the plane. In short, the facing surface 51 only needs to bulge smoothly toward the front shaft portion 34.

  As shown in FIGS. 5 and 7, the distal end portion 53 of the rear shaft portion 35 is formed in a bowl shape. That is, the distal end portion 53 includes a projecting surface 54 and a horizontal surface 55 projecting in the left-right direction. The projecting surface 54 is formed integrally and continuously with the facing surface 51 and projects symmetrically in the left direction and the right direction. As shown in FIG. 7, the overhang amount d is the largest at the left and right ends, and is zero at the top of the facing surface 51. The horizontal surface 55 is continuous with the edge portion of the overhanging surface 54, extends straight in the left-right direction, and continues to the rear shaft portion 35. That is, the projecting surface 54 and the horizontal surface 55 form steps on the left and right edge portions of the rear shaft portion 35. Furthermore, in the present embodiment, the overhang surface 54 is curved inward in the left-right direction. Thereby, the overhang | projection surface 54 is formed in the concave surface. The advantage of the protruding surface 54 being a concave surface will be described later.

3. <Hook configuration>

  FIG. 8 is a perspective view of the hook 32. FIG. 9 is an enlarged perspective view of a main part of the hook 32, and FIG. 10 is a cross-sectional view of the hook 32.

  The hook 32 is made of resin. As shown in FIG. 1 and FIG. 8, the hook 32 includes a base portion 56 and a key portion 57 formed in a block shape, which are integrally formed.

  The base 56 includes a core 58 (slider) and a pair of locking claws 59 and 60. The outer shape of the core 58 is substantially a cube. However, the core 58 includes a through hole 61. The through hole 61 has a rectangular shape and penetrates the core 58 in the vertical direction. A notch groove 62 is provided so as to be continuous with the through hole 61. The notch 62 is provided at the center of the rear surface 63 of the core 58 (that is, the surface facing the front plate 46 of the main body 31). The notch groove 62 is formed straight from the upper surface to the lower surface of the core 58 in the vertical direction. By providing the through hole 61 and the notch groove 62 in this way, a pair of engagement protrusions 64 and 65 are formed on the left side and the right side of the core 58.

  The locking claws 59 and 60 are respectively provided on the left and right edges of the upper surface of the core 58 and protrude upward. These locking claws 59 and 60 are formed in an elongated flat plate shape and are formed integrally with the core 58. The locking claws 59 and 60 are inclined so that their tips approach each other. Each of the locking claws 59, 60 can be elastically deformed. Since each of the locking claws 59 and 60 is elastically raised and lowered, the posture can be freely changed between a posture (first posture) in which the tips of the two are close to each other (first posture) and a posture in which they are separated (second posture).

  The core 58 is fitted into the slide base 43 of the front shaft portion 34, and can slide along the slide base 43. Specifically, the core 58 is fitted into the slide base 43 from above, whereby the front plate 46 is inserted into the through hole 61 and the engagement protrusions 64 and 65 are inserted into the engagement grooves 44 and 45. Is done. Accordingly, the core 58 functions as a slider that fits without sliding with the slide base 43 and slides relative to the slide base 43.

  When the core 58 is fitted into the slide base 43, the tips of the locking claws 59, 60 are always close to each other (see FIG. 8), so that the locking claws 59, 60 are as shown in FIG. It abuts against the abutment surface 50 of the check piece 47 provided on the slide base 43. That is, the locking claws 59 and 60 are in the first posture and come into contact with the contact surface 50. For this reason, the core 58 is restricted from sliding upward. When the core 58 is slid downward in this state, the locking claws 59 and 60 are relatively pressed against the inclined surface 49 of the check piece 47 and elastically displaced outward in the left-right direction. That is, the locking claws 59, 60 are displaced to the second posture, and the tips of the locking claws 59, 60 abut against the inclined surface 49. When the core 58 is slid further downward and the locking claws 59, 60 pass through the inclined surface 49, the locking claws 59, 60 are elastically returned to the first posture again and are adjacent to the contact surface 50. Contact the contact surface 50. That is, the check piece 47 and the locking claws 59 and 60 constitute a so-called ratchet mechanism, and therefore the core 58 can slide only from the distal end 38 side to the proximal end 36 side of the front shaft portion 34. It has become.

  As shown in FIG. 1, the key portion 57 is composed of an elongated rod-like member curved in a substantially U shape. The key portion 57 is integrally formed with the core 58. Therefore, when the key portion 57 is engaged with the curtain rail from above, the curtain hook 30 is hooked on the curtain rail. Although the shape of the key part 57 is not limited to such a substantially U shape, it is preferable that the key part 57 has a shape that can be hooked from above to below with respect to the curtain rail.

4). <Configuration of slide mechanism>

  The hook 32 is provided on the front shaft portion 34 via the slide mechanism 33. By providing the slide mechanism 33, as described above, the core 58 can slide only from the front end 38 side to the base end 36 side of the front shaft portion 34. As a result, the hook 32 is allowed to slide only from the distal end 38 side to the proximal end 36 side with respect to the front shaft portion 34, and the sliding from the proximal end 36 side to the distal end 38 side is restricted.

  The slide mechanism 33 includes the slide base 43, the core 58, a check piece 47 provided on the slide base 43, and locking claws 59 and 60 provided on the core 58. That is, the slide base 43, the check piece 47 provided on the slide base 43, the core 58 and the locking claws 59 and 60 provided on the core 58 also serve as a part of the slide mechanism 33. In addition, since the function of the slide mechanism 33 is as above-mentioned, the description is abbreviate | omitted.

5). <How to use curtain hooks>

  The curtain hook 30 according to the present embodiment is used as follows.

  First, the hook 32 is attached to the front shaft portion 34 of the main body 31. Specifically, the core 58 of the base portion 56 is inserted and fitted into the front shaft portion 34 from the front end 38 side of the front shaft portion 34. At this time, since the slide mechanism 33 is provided, the hook 32 can slide only from the distal end 38 side of the front shaft portion 34 toward the proximal end 36 side (that is, only downward in the vertical direction).

  The rear shaft portion 35 is inserted into the hanging pocket of the curtain upward in the vertical direction. Thus, the curtain liner is sandwiched between the front shaft portion 34 and the rear shaft portion 35, and the curtain is hooked on the hook 32 so as to be supported from below. Then, when the key portion 57 of the hook 32 is hooked on the curtain rail, the curtain is suspended on the curtain rail.

  As shown in FIG. 1 to FIG. 3, since the facing surface 51 of the rear shaft portion 35 swells smoothly toward the front shaft portion 34, the front shaft portion 34 and the rear shaft portion 35 reliably secure the curtain liner. Can be pinched. Moreover, since the front-end | tip part of the back axis | shaft part 35 is formed in hook shape, the operator can insert the back axis | shaft part 35 in the said pocket for suspension easily. Furthermore, since the front end portion of the rear shaft portion 35 is formed in a bowl shape, the rear shaft portion 35 once inserted into the hanging pocket does not easily come off. In addition, since the rear surface 52 of the rear shaft portion 35 is a flat surface, the rear shaft portion 35 is stably disposed in a state in which the rear shaft portion 35 is inserted into the suspension pocket, and is not contained in the suspension pocket. Stable rolling is prevented. In addition, since the back surface 52 of the rear shaft portion 35 is a flat surface, when the rear shaft portion 35 is inserted into the hanging pocket, large irregularities are not formed on the curtain.

  Since the hook 32 can slide up and down with respect to the main body 31, the height of the rear shaft portion 35 relative to the curtain rail is adjusted. That is, even if the length (length dimension) of the curtain body changes, the curtain is always arranged at a constant height. Moreover, when the base portion 56 of the hook 32 is inserted into the front shaft portion 34, as described above, the engagement grooves 44 and 45 provided in the front shaft portion 34 and the engagement protrusion 59 provided in the base portion 56, 60 and 60 are fitted together, the hook 32 is attached to the main body 31 without rattling. Therefore, the curtain is also supported stably.

  In addition, the slide mechanism 33 restricts the hook 32 from sliding upward and downward relative to the main body 31, so that when the curtain is hooked on the rear shaft portion 35, the front shaft portion 34 is caused by the weight of the curtain. Is restricted from moving downward relative to the hook 32. That is, the curtain does not shift downward. In such a slide restriction, the locking claws 59, 60 provided on the hook 32 abut on the check piece 47 of the main body 31, so that the base portion 56 only slides downward in the vertical direction with respect to the front shaft portion 34. Therefore, there is an advantage that the structure for realizing the slide regulation is very simple. Moreover, when the hook 32 slides with respect to the main body 31, the locking claws 59, 60 are elastically deformed to easily come into contact with the contact surface 50 of the check piece 47 provided on the main body 31. Canceled. Therefore, the operation for the operator to intentionally slide the hook 32 is very simple.

  In particular, in this embodiment, since the projecting surface 54 constituting the distal end portion 53 of the rear shaft portion 35 is curved in the left-right direction to form a concave surface, the operator can suspend the rear shaft portion 35 more easily. There is an advantage that it can be inserted into the pocket for use, and the rear shaft portion 35 is difficult to be removed from the pocket for suspension.

  The present invention can be applied to a curtain hook attached to a curtain.
