  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product.

  FIGS. 1-7 is a figure for demonstrating one Embodiment and its modification of the stroller and guard member by this invention. Of these, FIG. 1 shows the overall configuration of the stroller. A stroller 10 shown in FIG. 1 includes a stroller body 11 having a frame portion 15 having a pair of front legs 22 and a pair of rear legs 24, and a hand handle 13 that is swingably connected to the frame portion 15. ing. A front wheel 23 is rotatably held at the lower end of each front leg 22 of the stroller body 11, and a rear wheel 25 is rotatably held at the lower end of each rear leg 24.

  In the stroller 10 according to the present embodiment, the handle 13 is swung with respect to the frame portion 15 so that an operator (guardian) holds the handle 13 from the back side of the infant and operates the stroller 10. The stroller 10 is caused to travel so as to face forward in the direction of travel (the state shown in FIG. 1 and the state shown by the two-dot chain line in FIG. 2), and the handle 13 from the position on the front leg side where the operator faces the infant The baby stroller 10 is operated by gripping the baby stroller 10 so that the rear leg side of the baby stroller 10 is in the forward direction (the state shown by the solid line in FIG. 2). That is, the handle 13 is configured to be releasably fixed at a facing pressing position indicated by a solid line in FIG. 2 and a back pressing position indicated by a two-dot chain line in FIG. In addition, a known configuration can be adopted as the configuration that allows the handle 13 to swing with respect to the frame portion 15. Therefore, further detailed description is omitted in this specification.

  In the present embodiment, the stroller 10 is configured to be foldable as disclosed in JP 2008-254688A, for example, so as to be widely used. As a specific example, the stroller 10 can be configured as follows.

  The stroller body 11 (stroller 10) has a generally symmetric configuration around a lateral center plane extending along the front-rear direction. As shown in FIG. 1, the frame portion 15 in the present embodiment includes a pair of front legs 22 arranged on the left and right sides, a pair of rear legs 24 arranged on the left and right sides, and a pair of left and right sides, respectively. The armrest 28 has a pair of first link members 26 arranged on the left and right respectively. The upper end portion of the front leg 22 is connected to an armrest 28 disposed on the corresponding side (left side or right side) so as to be rotatable (swingable). Similarly, the upper end of the rear leg 24 is connected to an armrest 28 disposed on the corresponding side (left side or right side) so as to be rotatable (swingable). Moreover, the upper part of the 1st link material 26 is connected with the back part of the armrest 28 arrange | positioned at the corresponding side (left side or right side) so that rotation is possible (oscillation is possible).

  The frame portion 15 further includes a left second link member 18 that connects the left front leg 22 and the left first link member 26, and a right second link member 18 that connects the right front leg 22 and the right first link member 26. Have. Each of the second link members 18 has a front portion thereof rotatably connected to an intermediate portion of the front leg 22 and a rear portion thereof rotatably connected to a lower portion of the first link member 26. The frame portion 15 includes a left third link member 16 that connects the left rear leg 24 and the left first link member 26, and a right third link that connects the right rear leg 24 and the right first link member 26. And a material 16. Each third link member 16 is pivotally connected to a middle portion of the rear leg 24 at a part thereof, and is pivotally connected to a lower portion of the first link member 26 at the other portion. Yes.

  The handle 13 is slidably connected to the frame portion 15 having such a configuration. The handle 13 is connected to the corresponding third link member 16 at both ends of the U-shape so as to be rotatable (swingable). The handle 13 in the back pushing position is rotatably connected to the armrest 28 or the first link member 26. The rotation axis (swing center) of the handle 13 with respect to the third link member 16 is the rotation axis of the third link member 16 and the first link member 26, and the first link member 26 and the second link member. 18 may be coincident with the rotation axis line of 18.

  As shown in FIG. 11, as members extending in the lateral direction (width direction) of the stroller 10, a footrest 17 that connects between the pair of front legs 22, a rear connection member 19 that connects between the pair of rear legs 24, Is provided. Further, a guard member 40 is detachably attached to the pair of armrests 28. The guard member 40 will be described later.

  The stroller 10 having the overall configuration as described above can be folded by rotating the constituent members with respect to each other. Specifically, the third link member 16 is rotated in the clockwise direction in FIG. 2 with respect to the rear leg 24 by once pulling the handle 13 arranged at the back pushing position upward and then pushing downward. . With this operation, the armrest 28 and the second link member 18 are rotated clockwise in FIG. 2 with respect to the first link member 26. By such an operation, the handle 13 and the front leg 22 approach each other and are arranged substantially parallel in a side view, and the arrangement position of the handle 13 is lowered. As described above, the stroller 10 can be folded, and the size of the stroller along the front-rear direction and the vertical direction can be reduced. On the other hand, in order to unfold the stroller 10 from the folded state, a procedure reverse to the above-described folding operation may be performed.

  In the present specification, the terms “front”, “rear”, “upper” and “lower” with respect to the baby stroller are based on “infant riding in the baby stroller 10 in the unfolded state” unless otherwise specified. It means “front”, “rear”, “upper” and “lower”. Therefore, the “front-rear direction” of the stroller 10 corresponds to a direction connecting the lower left and upper right of the paper surface in FIG. Unless otherwise specified, “front” refers to the side on which the infant who rides faces, and the lower left side in FIG. 1 is the front side of the stroller 10. On the other hand, the “vertical direction” of the stroller 10 is a direction orthogonal to the front-rear direction and orthogonal to the ground contact surface of the stroller 10. Therefore, when the grounding surface of the stroller 10 is a horizontal plane, the “up and down direction” indicates a vertical direction. The “lateral direction” is the width direction, and is a direction orthogonal to both the “front-rear direction” and the “up-down direction”.

  Next, the guard member 40 will be described. As shown in FIG. 1, the guard member 40 is also called a guard arm, and is attached to the pair of armrests 28 of the stroller body 11 so as to extend in the width direction of the stroller 10. As shown in FIG. 1 and FIG. 2, the guard member 40 includes a pair of attachment portions 40 a that are attached to the stroller 10 while being spaced apart from each other in the width direction of the stroller 10, and a guard portion that extends between the pair of attachment portions 40 a. 40b. In the illustrated example, the right attachment portion 40 a is attached to the right armrest 28, and the left attachment portion 40 b is attached to the left armrest 28.

  As a specific configuration, the guard member 40 includes a right holding member 41 attached to the right armrest 28, a left holding member 41 attached to the left armrest 28, and a stack extending between the pair of holding members 41. And a body 50. The laminated body 50 is held by the holding member 41 on the corresponding side at both ends in the longitudinal direction. In this configuration, the attachment portion 40 a is configured by a pair of holding members 41 and a portion held by the holding member 41 of the stacked body 50. On the other hand, the guard part 40a is configured by a portion extending between the pair of holding members 41 of the laminated body 50, and faces the infant seated on the stroller 10 from the front. Further, at least one holding member 41 is removable from the corresponding armrest 28. Thereby, for example, when an infant gets on and off, the pair of armrests 28 can be opened.

  As shown in FIG. 5, the laminated body 50 is comprised from many layers. The laminated body 50 is integrated in a compressed state at a position that becomes an end portion in a cross section (cross section in FIG. 5) orthogonal to the longitudinal direction of the guard portion 40b in a portion constituting the guard portion 40b. The layers constituting the laminated body 50 are bonded to each other in a compressed state. That is, the end region of the laminated body 50 is formed as a press portion 51 having a smaller thickness than other regions. The laminated body 50 demonstrated here is integrated in the compressed state in the circumferential area | region used as a peripheral part. That is, the compressed press portion 51 is formed in a circumferential shape along the periphery of the stacked body 50.

  As shown in FIG. 3, the width of the press portion 51 is wide at both end portions in the longitudinal direction of the stacked body 50. As shown in FIG. 3, the laminated body 50 is connected to the holding member 41 in the press portion 51 that has been compressed to increase the rigidity. In the example shown in FIG. 3, most of the portion of the laminate 50 that forms the attachment portion 40 a is formed as the press portion 51. In the example shown in FIG. 3, a through hole 52 is formed in the press part 51, and a holding part (boss) 42 that passes through the through hole 52 is provided in the holding member 41. The laminated body 50 is held by the holding member 41 by the engagement between the grip portion 42 and the through hole 52.

  However, the present invention is not limited to this example, and as an example, the laminated body 50 may be held by the holding member 41 as shown in FIG. In the example shown in FIG. 4, the longitudinal end portion of the laminated body 50 constituting the press portion 51 is folded back and sewn along the sewing line Ld to a portion located inward in the longitudinal direction from the portion. It has been. A ring-shaped portion 53 is formed at the end portion in the longitudinal direction of the laminated body 50 by the folded portion. Then, according to the example shown in FIG. 4, the grip portion 42 made of, for example, a pin fixed to the holding member 41 passes through the ring-shaped portion 53 at the end portion in the longitudinal direction of the stack 50, thereby 50 is held by the holding member 41.

  Moreover, in the laminated body 50 demonstrated here, many layers which comprise the laminated body 50 are mutually joined not only in the compressed edge part but in the whole region of the opposing surface. More specifically, in this laminate 50, two adjacent layers are welded (heat seal, heat using a thermoplastic adhesive or using the thermoplasticity of the material constituting the layer itself). Have been glued).

  In addition, as shown in FIGS. 3 to 5, the side end surface of the stacked body 50 is covered with an end fabric (bias) 45. The end fabric 45 is sewn to the press part 51 of the laminated body 50 along the sewing line Lc, and extends circumferentially along the peripheral edge of the laminated body 50.

  By the way, the guard member 40 is provided mainly for the purpose of preventing an infant riding on the stroller 10 from unintentionally dropping from the stroller body 11. For this reason, the guard member is required to have a certain level of strength, typically not to be cut with a certain level of force. Moreover, the guard member 40 comes to be located in front of the infant seated on the stroller 10. Therefore, the baby may come into contact with the guard member 40 when the stroller 10 is running. For this reason, in order not to deteriorate riding comfort, the guard member 40 is also required to have flexibility and cushioning properties. Further, from the viewpoint of not inhibiting the folding operation, the guard member 40 is required to have flexibility and cushioning properties. The laminated body 50 of the guard member 40 has the following layer configuration so as to meet such a demand and to stably give a desired shape.

  First, the laminated body 50 includes a core member 60, a first outer member 71 provided on one side of the core member 60, and a second outer member 72 provided on the other side of the core member 60. Yes. The laminated body 50 includes a first outer fabric 73 joined to a surface of the first outer member 71 opposite to the core member 60 (that is, a surface on one side of the first outer member 71), and a second outer member. And a second front fabric 74 joined to a surface opposite to the core material 60 of 72 (that is, a surface on the other side of the second outer material 71). When the laminated body 50 is attached to the stroller 10 as one component of the guard member 40, the first front fabric 73 side of the laminated body 50 is disposed forward, and the second front fabric 74 of the laminated body 50 is arranged. The side is arranged rearward and faces an infant who rides on the stroller 10.

  As described above, two adjacent layers forming the stacked body 50 are bonded to each other. That is, the first outer fabric 73 and the first outer member 71 are joined together, the first outer member 71 and the core member 60 are joined together, the core member 60 and the second outer member 72 are joined together, and the second outer member 72 and The 2nd table | surface dough 74 is mutually joined. In the illustrated example, a thermoplastic bonding layer 75 is provided between the first front fabric 73 and the first outer material 71, and the first front fabric 73 and the first outer material 71 are welded via the bonding layer 75. ing. Further, the surface of the core material 60 on the first outer material 71 side has thermoplasticity, and the first outer material 71 and the core material 60 are welded using the thermoplasticity of the core material 60. Further, a thermoplastic bonding layer 76 is provided between the core material 60 and the second outer material 72, and the core material 60 and the second outer material 72 are welded via the bonding layer 76. Further, a thermoplastic joining layer 77 is provided between the second outer member 72 and the second outer fabric 74, and the second outer member 72 and the second outer fabric 74 are welded via the joining layer 77.

  The core member 60 mainly functions as a layer that imparts a certain degree of strength, more specifically, a certain degree of tensile strength or tensile strength to the guard member 40. That is, the core material 60 plays the role of the core material 92 in the conventional guard member 100 shown in FIG. Moreover, the core material 60 has an appropriate volume, and contributes to the realization of a desired shape to be applied to the laminate 50.

  In the illustrated laminate 50, the core member 60 includes a first thermoplastic elastomer layer 64, a first thermal adhesive fiber assembly 61, a thermoplastic bonding layer 66, a second thermal adhesive fiber assembly 62, and a second thermal adhesive fiber assembly 62. A thermoplastic elastomer layer 65 and a third thermal adhesive fiber assembly 63 are included in this order from the first outer member 71 side. The thermoplastic elastomer layers 64 and 65 are layers that soften and exhibit fluidity when heated, and return to an elastic body when cooled. That is, the thermoplastic elastomer layers 64 and 65 impart a predetermined strength to the laminate 50 while maintaining the flexibility of the laminate 50. As the thermoplastic elastomer layers 64 and 65, layers made of thermoplastic polyurethane can be used.

  On the other hand, the heat-adhesive fiber assemblies 61, 62, 63 are configured as a layer made of heat-adhesive fibers that can be melted by heating, for example, a nonwoven fabric made of heat-adhesive fibers. The heat-adhesive fiber assemblies 61, 62, 63 have a certain amount of bulk and can be shaped into a desired shape by heating and pressing. That is, the core material 60 including the heat-adhesive fiber aggregates 61, 62, and 63 can be given a desired three-dimensional shape by heating and pressing. In addition, the heat-adhesive fiber aggregates 61, 62, 63 generally have high tensile strength (tensile strength), and thereby, excellent strength can be imparted to the laminate 50. Furthermore, since the heat-adhesive fiber assemblies 61, 62, and 63 have a bulk, a cushioning property different from that of the first outer member 71 and the second outer member 72 described later can be imparted to the laminate 50. .

  In the illustrated example, the first heat-adhesive fiber assembly 61 and the second heat-adhesive fiber assembly 62 extend all the way to both ends of the laminate 50 in a cross section perpendicular to the longitudinal direction of the laminate 50. Not. The first thermal adhesive fiber assembly 61 and the second thermal adhesive fiber assembly 62 do not extend to the press part 51 of the laminate 50. On the other hand, the third heat-adhesive fiber assembly 63 arranged at the rearmost (most infant side) extends to the press part 51 of the laminated body 50 and extends to both end parts of the laminated body 50. In addition, the first thermal adhesive fiber assembly 61, the second thermal adhesive fiber assembly 62, and the third thermal adhesive fiber assembly 63 have different thicknesses. For this reason, the core member 60 has an asymmetric layer configuration centered on any surface orthogonal to the stacking direction of the stacked body 50. According to such a configuration, a desired three-dimensional shape, for example, a desired three-dimensional bent shape can be stably imparted to the laminate 50.

  The outer members 71 and 72 mainly function as a layer that imparts cushioning properties to the guard member 40. That is, the outer members 71 and 72 arranged at positions sandwiching the relatively high-strength core member 60 serve as the outer member 96 in the conventional guard member 100 shown in FIG. For example, the outer members 71 and 72 may be configured as a urethane layer having a certain volume and capable of expressing a desired cushioning property.

  The front cloths 73 and 75 form the outermost layer of the laminated body 50, and are parts that can be contacted by an infant sitting in a stroller and a guardian of the infant. For this reason, the front fabrics 73 and 75 can be made of a fabric that is soft to the touch or a fabric that easily removes dirt.

  The bonding layers 75, 76, 77 and the bonding layer 66 in the core member 60 are layers made of a thermoplastic adhesive and function as a layer for welding two adjacent layers. The bonding layers 75, 76, 77, 66 can be composed of various layers having thermoplastic properties. As a specific example, a thermoplastic nonwoven fabric can be used as the bonding layers 75, 76, 77, 66.

  As an example, the laminate 50 having the above-described configuration can be manufactured very easily by the hot pressing shown in FIG.

  In the hot press processing shown in FIG. 6, first, materials (fabrics, raw materials) that form the layers of the above-described laminated body 50 are laminated in the order described above. Next, the laminated material group is pressurized from both sides with a pair of dies 81 and 82 having cavities corresponding to the shape to be applied to the laminated body 50. At this time, the molds 81 and 82 are heated to a temperature equal to or higher than the temperature at which the material forming each layer of the laminate 50 is softened. Thereby, the material which comprises each layer of the laminated body 50 is welded mutually. At the same time, the material forming each layer of the laminate 50, in particular, the first heat-adhesive fiber assembly 61, the second heat-adhesive fiber assembly 62, and the third heat-adhesive fiber assembly 63 are formed into cavities of the molds 81 and 82. Deforms corresponding to the shape. Next, the laminate 50 is obtained by trimming the periphery of the molded product as necessary.

  According to the above manufacturing method, the laminated body 50 can be molded and the layers constituting the laminated body 50 can be joined (welded) by a single hot press process. That is, the laminated body 50 can be produced with high productivity, and the manufacturing cost of the guard member 40 can be greatly reduced.

  In addition, by appropriately adjusting the cavity shape of the molds 81 and 82 and the type and amount of the material forming each layer of the laminate 50, a desired cross-sectional shape can be stably imparted to the laminate 50. It becomes. At this time, not only a planar shape but also a desired three-dimensional shape can be stably imparted to the laminate 50. Therefore, it becomes possible to stably produce the laminated body 50 with the same shape (bend) as when attached to the stroller 10 in the unfolded state, and in this case, the attaching and detaching work of the guard member 40 to the stroller body 11 is easy. become.

  Further, in the end region of the obtained laminated body 50, a press portion 51 in which the respective materials are joined (welded) to each other in a compressed state is formed. In the guard member 40 using such a laminated body 50, the lamination | stacking state of the laminated body 50 will be stabilized, without performing complicated sewing. That is, the guard member 40 that can be manufactured at low cost can stably exhibit the function expected of the guard member 40.

  In addition, according to the manufacturing method using the above-described hot press, the materials are not only joined to each other in the press part 51 of the laminate 50, but also included in the laminate 50 in regions other than the press part 51. Two adjacent layers are joined (welded) to each other. That is, the stacked state of the stacked body 50 is extremely stable. Therefore, even when the laminated body 50 is twisted during use of the guard member 40, the laminated state of the laminated body 50 is stabilized, and thus the guard member 40 is expected to the guard member 40. It is possible to continue functioning stably.

  According to the present embodiment as described above, the guard member 40 that can be manufactured at low cost is stably given a desired shape designed with a high degree of freedom.
