Description

  The present invention relates to a cord gripping device and a solar shading device for detachably fixing an end of a lifting / lowering cord to a lower end portion of a shielding material suspended from a head box.

  As a kind of solar shading device, a curtain is known. The scooping curtain is supported by a lifting / lowering cord in which the shielding material is suspended from the head box and the lower end of the shielding material is suspended from the head box.

  A plurality of the lifting / lowering cords hang down in the width direction of the shielding material on the back surface of the shielding material, and are wound or rewound by a winding device in the head box by operating the lifting / lowering device.

  And if a raising / lowering cord is wound around a winding device, a shielding material will be rolled up sequentially from a lower end part. Further, if the lifting / lowering cord is rewound from the winding device, the shield material that has been lifted is sequentially lowered.

  By the way, in the hoisting curtain, when the lifting / lowering cord moves on the back side of the shielding material, the lifting / lowering cord may be caught by the occupant and hinder its behavior. Also, if the lifting / lowering operation is performed while the lifting / lowering cord is hooked on the handle of the sash located on the back side of the shielding material, an excessive operating force acts on the connecting tool between the lifting / lowering cord and the shielding material, so that the connection or shielding The material may be damaged.

  Therefore, by connecting and holding the first connecting member attached to the lower end of the shielding member and the second connecting member attached to the lower end of the lifting and lowering cord, the lower end of the lifting and lowering cord becomes the lower end of the shielding member. A technique for configuring for attachment is disclosed (see, for example, Patent Document 1).

  The first and second connecting members in Patent Document 1 are configured as “code catches”, and the connecting and holding of the code catches is released by a tensile force exceeding the weight of the shielding material acting on the first connecting members. Retained. Thereby, the behavior of the occupants and the like can be prevented and inadvertent breakage of the lifting device can be prevented in advance.

  A ring tape 3 made of a plurality of tape-shaped fabrics is arranged and sewn on the outdoor surface of the shielding material 2 at a plurality of locations (three locations in this example) in the vertical direction. A plurality of guide members 12 are fixed on the ring tape 3 at substantially equal intervals in the vertical direction, and a pair of upper and lower mounting rings 21 are attached near the lower end of the ring tape 3 (see FIG. 2). The cord gripping device 11 is attached to the attachment ring 21. An annular bag stitch portion is formed at the lower end portion of the shielding member 2, and a weight bar 4 is inserted into the annular bag stitch portion.

  A plurality of lifting / lowering cords 5 are suspended from the head box 1 via a plurality of guide members 12, and a lower end portion of the lifting / lowering cords 5 inserted through the guide members 12 is locked to the cord gripping device 11. Further, the upper end portions of the respective lifting / lowering cords 5 are guided in the head box 1, led out from the one end side of the head box 1 to the outside inside the room, and are suspended and attached to the upper end portion of the equalizer 9. As long as the guide member 12 can guide the lifting / lowering cord 5, the guide member 12 can be configured as a C-shaped member that allows the lifting / lowering cord 5 to be detachable. When the load is applied, the lifting / lowering cord 5 is separated from the guide member 12.

  One end of the operation cord 10 is attached to the lower end portion of the equalizer 9, and the other end of the operation cord 10 passes through an annular bag stitch portion at the lower end portion of the shielding member 2 after passing through a predetermined separable connecting member.

(Cord gripping device of Example 1)
First, with reference to FIG.3 and FIG.4, the cord holding apparatus 11 of Example 1 in the solar radiation shielding apparatus of one Embodiment by this invention is demonstrated. FIG. 3 is a perspective view showing a schematic configuration of the cord gripping device 11 of Example 1 in the solar radiation shielding device according to the embodiment of the present invention. FIG. 4 is a side view showing the operation of the cord gripping device 11 of Example 1 in the solar radiation shielding device of one embodiment according to the present invention.

  The cord gripping device 11 according to the first embodiment includes a first connecting member 11a that is attached so as to follow the lower end portion of the shielding member 2 following the surface of the shielding member 2, and a first connection member 11a that attaches the lower end of the lifting cord 5. It is comprised from the 2 connection member 11b.

  The first connecting member 11a is located between the surface of the shielding member 2 and the second connecting member 11b. And it is comprised so that the 1st connection member 11a and the 2nd connection member 11b may mutually engage and be connected and hold | maintained always.

  On the other hand, when a predetermined tensile force acts on the lifting / lowering cord 5 in the direction in which the second connecting member 11b is pulled away from the surface of the shielding member 2 to which the first connecting member 11a is attached, the first connecting member 11a and the second connecting member. 11b is disengaged, and the first connecting member 11a and the second connecting member 11b are separated.

  More specifically, the first connecting member 11a has a substantially rectangular parallelepiped outer shape, and is hooked and fixed at two places on the upper and lower surfaces of the first connecting member 11a by the attachment ring 21 attached to the lower end portion of the shielding material 2, respectively. A substantially C-shaped hooking portion 111 is integrally provided (see FIG. 2). The attachment ring 21 may be annular or C-shaped, and can have any shape as long as it can be hooked and fixed by the hook portion 111. Thereby, the 1st connection member 11a is fixed so that the lower end part of the shielding material 2 may follow the surface of the shielding material 2, and may follow. In addition, although this example demonstrates the example which fixes the 1st connection member 11a so that it may follow the surface of the shielding material 2 with the attachment ring 21 and the hook part 111, the 1st connection member 11a is covered with the shielding material 2. Any other fixing method may be used as long as it can be fixed so as to follow the surface.

  For example, the first connecting member 11 a may be fixed on the ring tape 3 using the hook-and-loop fastener 6. More specifically, as shown in FIG. 5 (a), the ring tape 3 is provided with a hook-and-loop fastener (female) 6b, and a hook-and-loop fastener (male) 6a is provided over the entire mounting surface of the first connecting member 11a. The first connecting member 11a can be fixed to the ring tape 3 so as not to be relatively rotatable in the front-rear direction. Alternatively, while the upper end of the first connecting member 11a is attached by the mounting ring 21 and the hooking portion 111, a plate-like protruding portion 120 is provided at the lower end of the first connecting member 11a, and this protruding portion 120 is used as the shielding material 2. It can be fixed together with the weight bar 4 along the surface. More specifically, as shown in FIG. 5B, a protrusion 120 that can be inserted into the sewed portion of the weight bar 4 is provided at the lower end of the first connecting member 11a so as to follow the surface of the shielding member 2. It can also be supported.

  As shown in FIG. 5C, the lower end of the first connecting member 11a is fixed by the mounting ring 21 and the hooking portion 111, and a thin plate-like protrusion 121 is provided at the upper end of the first connecting member 11a. The locking portion 121a on the protruding portion 121 may be fixed by sewing to the ring tape 3 (or the shielding material 2). Furthermore, such a protrusion 121 can be provided on the upper and lower ends of the first connecting member 11a and sewn to the ring tape 3 (or the shielding material 2).

  As another fixing method, instead of providing a pair of upper and lower attachment rings 21 on the ring tape 3 in the vicinity of the lower end of the ring tape 3, a plurality of guide members 12 provided on the ring tape 3 at substantially equal intervals are used. Thus, the first connecting member 11a can be fixed to the shielding member 2. More specifically, as shown to Fig.6 (a), the 1st connection member 11a is fixed between the guide members 12 located up and down continuously in the lowermost end side of the shielding material 2. As shown in FIG. At this time, the lower guide member 12 is hooked with the hook portion 111 on the lower end side of the first connecting member 11a, and the upper end 124a of the string-like connection cord 124 is fixed to the nearest upper guide member 12 so that the connection cord 124 is suspended. The first connecting member 11a is fixed to the shielding member 2 by locking the lower end of the connection cord 124 with the locking hole 125 provided at the upper end of the first connecting member 11a.

  Here, in order to prevent the connection cord 124 from being loosened or forming a large loop, it is preferable to support the first connecting member 11a in a suspended state with the connection cord 124 stretched. Therefore, for example, as shown in FIG. 6B, the lower end of the connection cord 124 that connects the upper end to the nearest upper guide member 12 and hangs down is temporarily engaged through the insertion hole 126 provided on the ring tape 3. It can also be configured to be locked by the locking hole 125 of the first connecting member 11a. The connection cord 124 can be a ball chain instead of a string-like form.

  Here, the configuration will be described in detail with reference to FIG. Engagement protrusions 114 are formed on the non-fixed side edges of the upper and lower surfaces of the first connecting member 11a.

  Further, the second connecting member 11b is formed such that an engaging claw portion 115 that can engage with the engaging convex portion 114 of the first connecting member 11a extends from the upper and lower ends of the base portion 116 of the second connecting member 11b. Therefore, the first connecting member 11a and the second connecting member 11b are always engaged with each other and held.

  An insertion hole 113 through which the lifting / lowering cord 5 is inserted is provided on the upper end surface protruding from the upper end of the base portion 116 of the second connecting member 11b, and the winding extends from substantially the center of the base portion 116 of the second connecting member 11b. A disk is provided at the end of the shaft, and a reel-like cord locking portion 112 is formed as a whole. That is, the lifting / lowering cord 5 inserted through the insertion hole 113 can be locked to the winding shaft of the reel-shaped code locking portion 112 by winding. In addition, as long as it can attach the raising / lowering cord 5 with respect to the 2nd connection member 11b, you may fix with the other arbitrary fixing methods.

  Thus, in the state where the first connecting member 11a is located between the surface of the shielding member 2 and the second connecting member 11b, the first connecting member 11a and the second connecting member 11b The surfaces of the shielding material 2 are stably engaged with each other in a substantially parallel state, and the end of the lifting / lowering cord 5 is detachably fixed to the shielding material 2.

  On the other hand, a case where a predetermined tensile force acts on the lifting / lowering cord 5 in a direction in which the second connecting member 11b is pulled away from the surface of the shielding member 2 to which the first connecting member 11a is attached will be described with reference to FIG. As shown in FIG. 4, when the foreign object Ob is sandwiched between the shielding member 2 and the lifting / lowering cord 5, the first connection member 11 a and the second connection member 11 b are disengaged and the first and second connection members are immediately released. It is possible to respond so that the connecting members 11a and 11b are separated. That is, the first connecting member 11a is attached to the surface of the lower end portion of the shielding member 2 at two or more points in the hanging direction of the shielding member 2. The second connecting member 11b has the engaging claw portion 115 as a base. Since it extended from the upper and lower ends of the part 116 and engaged with the engagement convex part 114 of the 1st connection member 11a, it was attached to the 2nd connection member 11b from the surface of the shielding material 2 which attaches the 1st connection member 11a. When the predetermined inclination force is applied to the lifting cord 5 and the first and second connecting members 11a and 11b are immediately separated from each other.

  As described above, according to the cord gripping device 11 of the first embodiment illustrated in FIGS. 3 to 6, the safety when the foreign object Ob is caught between the lower end portion of the shielding member 2 and the lifting / lowering cord 5. Can be secured, and the separation response can be improved. Even when the foreign object Ob is caught on the lifting / lowering cord 5 on the guide member 12, the lifting / lowering cord 5 is separated from the guide member 12.

(Cord gripping device of Example 2)
Next, with reference to FIG.7 and FIG.8, the cord holding apparatus 11 of Example 2 in the solar radiation shielding apparatus of one Embodiment by this invention is demonstrated. FIG. 7: is a perspective view which shows schematic structure of the cord holding apparatus 11 of Example 2 in the solar radiation shielding apparatus of one Embodiment by this invention. FIGS. 8A and 8B are explanatory diagrams for explaining the structure and operation of the cord gripping device 11 of Example 2 in the solar radiation shielding device of one embodiment according to the present invention. In addition, the same reference number is attached | subjected to the component which functions similarly to Example 1. FIG.

  The cord gripping device 11 according to the second embodiment includes a first connecting member 11a that is attached to follow the lower end portion of the shielding member 2 along the surface of the shielding member 2, and a first connection member 11a that attaches the lower end of the lifting cord 5. The point comprised from 2 connection member 11b, the 1st connection member 11a is located between the surface of the shielding material 2, and the 2nd connection member 11b, and always the 1st connection member 11a and the 2nd connection member 11b are. A predetermined tensile force is applied in the direction in which the second connecting member 11b is pulled away from the surface of the shielding member 2 to which the first connecting member 11a is attached, and the point where the second connecting member 11b is separated from the surface. As in the first embodiment, the first connecting member 11a and the second connecting member 11b are disengaged when acting on each other, and the first connecting member 11a and the second connecting member 11b are separated. It is.

  However, in the cord gripping device 11 of the second embodiment, the shapes of the first connecting member 11a and the second connecting member 11b are different, and the first connecting member 11a has a substantially convex outline and the second connecting member. 11b has a substantially U-shaped outline.

  More specifically, as shown to Fig.8 (a), the 1st connection member 11a has the support part 116 which protrudes so that the base end part 117 of the 2nd connection member 11b can be supported, and the 2nd connection member 11b. An engagement receiving portion 118a that engages with the engagement portion 118b and acts as a base shaft 118 is provided.

  The second connecting member 11b has a base end portion 117 for attaching the lower end of the lifting / lowering cord 5 and a pair of arm portions extending downwardly in a bifurcated manner from the base end portion 117 and having an engaging portion 118b in the vicinity of the tip end thereof. 119.

  The first connecting member 11a and the second connecting member 11b are engaged with the engaging shaft 118b and the engaging portion 118b to form the base shaft 118, and the base end portion 117 is supported by the rotational engagement based on the base shaft 118. The portion 116 is supported.

  At approximately three locations above and below the first connecting member 11a, there are provided substantially C-shaped hook portions 111 that are hooked and fixed to the attachment ring 21 attached to the lower end portion of the shielding member 2, respectively. Thereby, the 1st connection member 11a is fixed so that the lower end part of the shielding material 2 may follow the surface of the shielding material 2, and may follow. In addition, although this example demonstrates the example which fixes the 1st connection member 11a so that it may follow the surface of the shielding material 2 with the attachment ring 21 and the hook part 111, the 1st connection member 11a is covered with the shielding material 2. Any other fixing method may be used as long as it can be fixed so as to follow the surface. For example, the fixing method shown in FIGS. 5 and 6 described above can be applied.

  A groove 117a is formed inside the base end 117 of the second connecting member 11b. The lifting / lowering cord 5 is inserted through an insertion hole that passes from the upper side to the lower side of the base end portion 117, and is then attached by the knot ball 5a. The knot ball 5a is accommodated in the groove portion 117a.

  Then, as shown in FIG. 7, when the first connecting member 11a and the second connecting member 11b are engaged with each other, the first connecting member 11a is connected so as to substantially receive the second connecting member 11b. Hold.

  Although the pair of arm portions 119 of the second connecting member 11b extend so as to be elastically deformable, as shown in FIG. 7, when the first connecting member 11a and the second connecting member 11b are engaged with each other. Further, the support portion 116 supports the base end portion 117 so as to prevent elastic deformation of the pair of arm portions 119.

  In this way, the first connecting member 11a and the second connecting member 11b are stably engaged with each other in a state where the hanging direction of the lifting / lowering cord 5 and the surface of the shielding member 2 are substantially parallel to shield the end of the lifting / lowering cord 5. It is detachably fixed to the material 2.

  On the other hand, when a predetermined tensile force acts on the lifting / lowering cord 5 by a foreign object Ob as shown in FIG. 4, when the relative rotation to a predetermined angle occurs, the support portion 116 is disengaged from the base end portion 117. Since the pair of arm portions 119 are in a state of being easily elastically deformed, the first receiving member 11a and the second connecting member 11a and the second connecting member are disengaged by being elastically deformed so that the engagement receiving portion 118a and the engaging portion 118b are disengaged. The member 11b is configured to be separated.

  The predetermined relative rotation angle is an inclination angle generated when the shielding material 2 is stacked on the cord gripping device 11 during folding (a tensile force perpendicular to the surface of the shielding material 2 is applied to the lifting / lowering cord 5 during folding). It is set larger than the inclination angle of the cord gripping device 11 itself with respect to the vertical direction. That is, when the shielding member 2 is moved up and down, the cord gripping device 11 itself is allowed to tilt, and the second connecting member 11b is not easily deformed easily with respect to the first connecting member 11a.

  Further, as shown in FIG. 8 (b), the engagement receiving portion 118a and the engagement portion 118b are in contact with each other when the first connection member 11a and the second connection member 11b are engaged and held together. When the predetermined pulling force is applied to the lifting / lowering cord 5 so as to stabilize the engagement, the first connecting member 11a and the second connecting member 11b are inclined so as to be separated. ing.

  Therefore, when the foreign object Ob is sandwiched between the shielding member 2 and the lifting / lowering cord 5, the first connection member 11a and the second connection member 11b are disengaged and the first and second connection members 11a and 11b are immediately released. Can respond to separation. That is, the 1st connection member 11a is hold | maintained along the drooping direction of the shielding material 2 with respect to the surface of the lower end part of the shielding material 2, follows the surface of the shielding material 2, and attaches the 1st connection member 11a. When the second connecting member 11b is inclined away from the surface of the shielding member 2 by a predetermined angle, elastic deformation is easily achieved, and when a predetermined tensile force acts on the elevating cord 5, the first and second connecting members are immediately applied. 11a and 11b come to separate.

  Moreover, since the 2nd connection member 11b is hold | maintained along the drooping direction of the shielding material 2 with respect to the 1st connection member 11a, and follows the surface of the shielding material 2, isolation | separation responsiveness improves. Since the support portion 116 is provided so that elastic deformation does not easily occur during the elevation, unnecessary separation during the elevation can be avoided.

  Thus, in the cord gripping device 11 of the second embodiment, the first connecting member 11a and the second connecting member 11b are engaged with each other so as to be relatively rotatable, and the first connecting member 11a is the second connecting member. The elastic deformation is prevented until 11b rotates by a predetermined angle, and when the predetermined angle is exceeded, the elastic deformation is allowed.

  According to the cord gripping device 11 of the second embodiment, since the angle for shifting to the separation state can be arbitrarily set, for example, when the shielding material 2 is wound (when the shielding material 2 is configured in a bellows shape) It is possible to easily configure the angle setting for shifting to the separated state so that the angle is not separated at the inclination angle associated with the convolution) and shifting to the separated state at an angle larger than that.

  As described above, according to the cord gripping device 11 of the second embodiment, it is possible to ensure safety when the foreign object Ob is caught between the lower end portion of the shielding member 2 and the lifting cord 5. Separation response can be improved.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. For example, in the above-mentioned embodiment and each example, although the example which has a specific shape was demonstrated, if it is a shape which produces the same effect | action and effect, it can be set as another shape. Further, the cord gripping device 11 of each embodiment can be applied to a pleated curtain or the like that allows the shielding material 2 to be folded, as well as a folding curtain that enables the shielding material 2 to be rolled up.

  According to the present invention, it is possible to ensure safety when a foreign object is caught between the lower end portion of the shielding material and the lifting / lowering cord, and to improve the separation response. It is useful for the application of a solar shading device that requires a holding device.
