Description

Protective member and laminated body Field of invention

The present invention relates to a guard member that is attached to the stroller in a width direction of the stroller. Further, the present invention relates to a stroller having a protective member.

Background of the invention

For example, as disclosed in JP06-037052U, in many strollers, a guard member (also referred to as a guard arm) extending in the width direction of the stroller is mounted in front of the infant in the stroller. From the viewpoint of ensuring the safety of the stroller while walking or not obstructing the folding operation, the protective member is required to have various characteristics such as strength, flexibility, and cushioning properties.

In order to meet such requirements, a protective member as shown in Fig. 8 has recently been used. The protective member 100 shown in Fig. 8 is composed of an outer covering fabric 99 and a laminated body 91 which is disposed in the outer covering fabric 99 and is composed of a plurality of cloth materials. The laminated body 91 has a core material 92 composed of a polypropylene belt 93 and two polypropylene sheets 94, and a foam material 96 which is overlapped on both outer sides of the core material 92. Further, each of the foamed materials 96 is covered with a protective cloth material 97.

According to the conventional protective member shown in Fig. 8, the protective member can be imparted with desired characteristics by adjusting the characteristics of the layers. On the other hand, It is necessary to prevent the positional deviation caused by the number of layers, and the protective member cannot perform the intended function. Therefore, the polyethylene tape constituting the core material and the two polypropylene sheets (for example, the sewn line L1) are to be sewn, and the outer portions must also be sewn at both ends (for example, the sewn line L2) so as to surround the core material. Therefore, not only the number of components of the laminated body is large, but also the manufacturing cost is increased from the viewpoint of the workability accompanying sewing.

Moreover, in the general state, the laminated structure of the protective member extends along the curved surface. Therefore, the shield member should have a three-dimensional shape so as to be along the curved surface in a state where no external force is applied. However, with the manufacturing method as described above, it is difficult to impart a fixed three-dimensional shape to the protective member.

Form for implementing the invention

An embodiment of the present invention will be described below with reference to the drawings. In addition, in the drawings of the present specification, for the sake of illustration and easy understanding, the scale ratio of the scale and the length and the width are appropriately adjusted, and the emphasis is placed on the actual object.

1 to 7 are views for explaining an embodiment of a baby carriage and a protective member of the present invention and a modification thereof. 1 shows the overall structure of the stroller. The stroller 10 shown in FIG. 1 includes a stroller body 11 having There is a frame portion 15 having a pair of forefoot 22 and a pair of rear legs 24, and a hand grip 13 that is slidably coupled to the frame portion 15. At the lower end of each of the front legs 22 of the stroller body 11, a front wheel 23 is rotatably held, and a rear wheel 25 is rotatably held at a lower end of each of the rear legs 24.

In the stroller 10 of the present embodiment, the operation can be performed by the operator 13 (the protector) holding the grip 13 from the back side of the infant to operate the stroller 10 by swinging the grip 13 against the frame portion 15. The infant is allowed to walk in front of the traveling direction so that the stroller 10 walks (the state shown in FIG. 1 and the two-dot line in FIG. 2); and the operator holds the foot from the front side before the face of the infant. The stroller 10 is operated by holding the grip 13, and the stroller 10 is moved to the front side of the stroller 10 to make the stroller 10 travel (the state shown by the solid line in Fig. 2). That is, the grip 13 is configured to be liberated from the opposite push position shown by the solid line in FIG. 2 and the back push position shown by the two-dot chain line in FIG. Further, the configuration in which the grip 13 can be rocked toward the frame portion 15 can be of a known configuration. Therefore, further detailed description is omitted in the present specification.

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

The stroller body 11 (stroller 10) as a whole has a substantially symmetrical structure with a lateral center plane extending in the front-rear direction as a center. As shown in Fig. 1, the frame body portion 15 of the present embodiment has a pair of front legs 22 disposed on the right and left sides, a pair of rear legs 24 disposed on the right and left sides, and a pair of armrests 28 disposed on the left and right sides; The pair of first link members 26 are disposed on the right and left sides, respectively. The upper end of the front foot 22 is rotatably (tiltable) coupled to the front end Place the elbow 28 on the corresponding side (left or right). Similarly, the upper end of the rear leg 24 is rotatably (tiltable) coupled to the armrest 28 disposed on the corresponding side (left or right side). Further, the upper portion of the first link member 26 is rotatably (shaken) coupled to the rear portion of the armrest 28 disposed on the corresponding side (left side or right side).

The frame portion 15 further includes a left second link member 18 that connects the left forefoot 22 and the left first link member 26, and a right second link member 18 that connects the right forefoot 22 to the right first link Rod 26. Each of the second link members 18 is rotatably coupled to the intermediate portion of the front leg 22, and its rear portion is rotatably coupled to the lower portion of the first link member 26. Further, the frame portion 15 further 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 member 16 that connects the right rear leg 24 and the right first. 1 link material 26. Each of the third link members 16 is partially rotatably (rotatably coupled) to the intermediate portion of the rear leg 24, and the other portion is rotatably coupled to the lower portion of the first link member 26.

With respect to the frame portion 15 composed of such a structure, the grips 13 are slidably coupled. The grip 13 is connected to the third link member 16 on the corresponding side so as to be rotatable (shakeable) at both ends of the U-shape. The grip 13 at the rear push position is rotatably coupled to the armrest 28 or the first link member 26. Further, the grip 13 may be related to the rotation axis (shaking center) of the third link member 16 and the third link member 16 and the first link member 26, and the first link member 26 and the second link member. The axis of rotation of the material 18 is uniform.

As shown in FIG. 11, as a member extending in the lateral direction (width direction) of the stroller 10, a pedal 17 is provided which is coupled between the pair of front legs 22, and a rear connecting member 19 which is coupled to the pair of rear legs 24. between. In other words, A pair of armrests 28 are detachably mounted with a guard member 40. This protective member 40 will be described later.

The stroller 10 having the above-described overall configuration can be folded by rotating the respective constituent members. Specifically, the grip 13 disposed at the rear push position is temporarily pulled up and then pushed downward, so that the third link member 16 is rotated clockwise toward the rear leg 24 in FIG. . With this operation, the armrest 28 and the second link member 18 are rotated in the clockwise direction in FIG. 2 with respect to the first link member 26. With this type of operation, the grip 13 is placed approximately parallel to the forefoot 22 from the side, and the position of the grip 13 is lowered. The stroller 10 can be folded as described above to be miniaturized along the front and rear directions of the stroller and the up and down direction. In addition, when the stroller 10 is to be unfolded from the folded state, the procedure opposite to the folding operation described above may be followed.

In addition, in this specification, the terms "before", "after", "upper" and "below" of the stroller mean that the stroller 10 is in the unfolded state unless otherwise specified. Infants and young children are based on "before", "after", "up" and "down". Therefore, the "front-rear direction" of the stroller 10 corresponds to the direction of the lower left and upper right sides of the connecting sheet of Fig. 1. Then, as long as there is no special instruction, "front" refers to the side facing the infant, and the lower left side of the paper of Fig. 1 is the front side of the stroller 10. The "up and down direction" of the stroller 10 refers to a direction orthogonal to the front-rear direction and orthogonal to the ground plane of the stroller 10. Therefore, when the ground plane of the stroller 10 is a horizontal plane, the "up and down direction" means the vertical direction. Further, "horizontal" refers to the width direction, which is orthogonal to the directions of both the "front-rear direction" and the "up-and-down direction".

Next, the protective member 40 will be described. As shown in Figure 1, protection The member 40, also referred to as a guard arm, extends in the width direction of the stroller 10 and is mounted to one of the pair of armrests 11 of the stroller body 11. As shown in FIGS. 1 and 2, the guard member 40 has a pair of mounting portions 40a that are attached to the stroller 10 in a width direction of the stroller 10, and a guard portion 40b that extends over a pair of mountings. Between the parts 40a. In the illustrated example, the mounting portion 40a on the right side is attached to the armrest 28 on the right side, and the mounting portion 40b on the left side is attached to the armrest 28 on the left side.

As a specific configuration, the shield member 40 has a right side holding member 41 attached to the right side armrest 28, a left side holding member 41 attached to the left side armrest 28, and a laminated body 50 extending from the pair of holding members Member 41. Both ends of the laminated body 50 in the longitudinal direction are held by the holding members 41 on the corresponding sides. In this configuration, the attachment portion 40a is constituted by a pair of holding members 41 and a portion of the laminated body 50 held by the holding member 41. Further, the guard portion 40a is constituted by a portion of the laminated body 50 that extends between the pair of holding members 41, and faces the front side from the infant that rides on the stroller 10. Also, at least one of the retaining members 41 can be removed from the elbow rest 28 on the corresponding side. Thereby, for example, when the infant gets on and off the vehicle, the pair of elbows 28 can be opened.

As shown in Fig. 5, the laminated body 50 is composed of a plurality of layers. The laminated body 50 is in a portion constituting the shield portion 40b, and is integrated in a compressed state in a cross section orthogonal to the longitudinal direction of the shield portion 40b (a cross section of FIG. 5), in other words, in the compressed state. In the compressed state, the layers constituting the laminated body 50 are joined to each other. That is, the end region of the laminated body 50 is formed as a relatively small thickness of the pressing edge portion 51 as compared with other regions. The laminated body 50 described here is integrated in a compressed state in a peripheral region as a peripheral portion. That is, the compressed pressure edge portion 51 is along the laminated body 50. The circumference is formed into a circumference.

As shown in FIG. 3, the width of the press edge portion 51 is widened at both end portions in the longitudinal direction of the laminated body 50. As shown in FIG. 3, the laminated body 50 is connected to the holding member 41 at the pressure edge portion 51 which is compressed and has increased rigidity. In the example shown in FIG. 3, a portion of the laminated body 50 constituting the mounting portion 40a is formed as a crimping portion 51. In the example shown in FIG. 3, a through hole 52 is formed in the press edge portion 51, and a holding portion (hub) 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 of the grip portion 42 with the through hole 52.

However, the present invention is not limited to this example. 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 pressure edge portion 51 is folded back, and is sewn along the sewing line Ld at a portion located inward in the longitudinal direction from the portion. The wheel portion 53 is formed at the end portion of the laminated body 50 in the longitudinal direction by the folded portion. Then, according to the example shown in FIG. 4, the wheel portion 53 of the longitudinal end portion of the laminated body 50 is inserted by the holding portion 42 fixed to the holding member 41 and composed of, for example, a pin or the like, so that the wheel portion 53 of the longitudinal end portion of the laminated body 50 is inserted. The laminated body 50 is held by the holding member 41.

Further, in the laminated body 50 described above, a plurality of layers constituting the laminated body 50 are joined to each other not only at the end portion to be compressed but also in the entire region of the opposing surface. More specifically, in the laminated body 50, the adjacent two layers are welded using a thermoplastic adhesive or by the thermoplasticity of the material constituting the layer (heat sealing, heat subsequent).

Further, as shown in FIGS. 3 to 5, the side end faces of the laminated body 50 are covered with an end cloth (twill) 45. The end cloth 45 is sewn to the pressing edge portion 51 of the laminated body 50 along the sewing line Lc, and extends circumferentially along the periphery of the laminated body 50.

The guard member 40 is mainly provided for preventing the infant who is riding on the stroller 10 from inadvertently dropping from the stroller body 11 as a main purpose. Therefore, the guard member 40 is required to have a certain degree of strength, and is typically required to be cut by a certain degree of force. Further, the guard member 40 is located in front of the infant who is seated on the stroller 10. Therefore, the infant sometimes comes into contact with the guard member 40 when the stroller 10 is walking. Therefore, in order not to deteriorate the ride comfort, the protective member 40 is also required to have flexibility or cushioning properties. Further, from the viewpoint of not impeding the folding operation, the protective member 40 is also required to have flexibility or cushioning properties. In order to meet the requirements of the class, the desired shape can be stabilized, and the laminated body 50 of the protective member 40 has the following layer structure.

First, the laminated body 50 has a core material 60, a first exterior material 71 provided on one side of the core material 60, and a second exterior material 72 provided on the other side of the core material 60. Further, the laminated body 50 further includes a first table cloth 73 joined to a surface of the first exterior member 71 opposite to the core member 60 (that is, a surface on one side of the first exterior member 71); and a second The surface cloth material 74 is joined to the surface of the second exterior material 72 opposite to the core material 60 (that is, the surface on the other side of the second exterior material 71). When the laminated body 50 is attached to the stroller 10 as one of the components of the protective member 40, the first table cloth 73 side of the laminated body 50 is disposed in the front side, and the second table cloth 74 side of the laminated body 50 is disposed in the rear side. It is opposite to the infant who rides on the stroller 10.

As described above, the adjacent two layers constituting the laminated body 50 are joined to each other. In other words, the first table cloth 73 and the second table cloth 74 are joined to each other, and the first outer member 71 and the core member 60 are joined to each other, and the core member 60 and the second outer member 72 are joined to each other, that is, the second member. The exterior material 72 and the second table cloth 74 are joined to each other. In the illustrated example, a thermoplastic is provided between the first watch fabric 73 and the first exterior member 71. The bonding layer 75 is welded to the first table cloth 73 and the first exterior member 71 via the bonding layer 75. Moreover, the surface of the core material 60 on the side of the first exterior material 71 has thermoplasticity, and the first exterior material 71 and the core material 60 are welded by the thermoplastic material of the core material 60. Further, a thermoplastic bonding layer 76 is provided between the core member 60 and the second exterior member 72, and the core member 60 and the second exterior member 72 are welded via the bonding layer 76. Further, a thermoplastic bonding layer 77 is provided between the second exterior material 72 and the second surface cloth 74, and the second exterior material 72 and the second surface cloth material 74 are welded via the bonding layer 77.

The core material 60 mainly functions as a layer that imparts a certain degree of strength to the shield member 40, more specifically, a certain degree of tensile strength or tensile strength. That is, the core material 60 functions as the core material 92 in the conventional protective member 100 shown in FIG. Further, the core material 60 has an appropriate volume and contributes to achieving a desired shape to be imparted to the laminated body 50.

In the laminated body 50 shown in the drawing, the core material 60 includes the first thermoplastic elastomer layer 64, the first thermal adhesive fiber assembly 61, the thermoplastic bonding layer 66, and the second in the following order from the first exterior material 71 side. The thermoplastic elastomer layer 62, the second thermal adhesive fiber assembly 65, and the third thermal adhesive fiber assembly 63. The thermoplastic elastomer layers 64 and 65 are layers which are softened by heating and exhibit fluidity, and if they are cooled, return to the properties of the elastomer. That is, the thermoplastic elastomer layers 64 and 65 maintain the flexibility of the laminated body 50 while imparting a predetermined strength to the laminated body 50. The thermoplastic elastomer layers 64, 65 may use a layer composed of a thermoplastic polyurethane.

Further, the thermal adhesive fiber aggregates 61, 62, and 63 are composed of a layer composed of heat-fusible heat-bonding fibers, and are formed of, for example, a non-woven fabric composed of heat-bonding fibers. Thermal adhesive fiber aggregates 61, 62, 63 has a certain volume and can be shaped into a desired shape by heat and pressure. That is, the core material 60 including the thermal adhesive fiber assemblies 61, 62, 63 can be imparted with a desired three-dimensional shape by heat and pressure. Further, the thermal adhesive fiber aggregates 61, 62, and 63 generally have high tensile strength (tensile resistance), whereby the laminated body 50 can be imparted with good strength. In other words, since the thermal adhesive fiber assemblies 61, 62, and 63 have a volume, the laminate 50 can be provided with a cushioning property different from that of the first exterior material 71 and the second exterior material 72 which will be described later.

In the illustrated example, the first thermal adhesive fiber assembly 61 and the second thermal adhesive fiber assembly 62 are perpendicular to the longitudinal direction of the laminated body 50 and do not extend to the laminated body 50. Both ends. Then, the first thermal adhesive fiber assembly 61 and the second thermal adhesive fiber assembly 62 do not extend to the pressure edge portion 51 of the laminated body 50. On the other hand, the third thermal adhesive fiber assembly 63 disposed on the rearmost side (mostly on the infant side) extends into the pressing edge portion 51 of the laminated body 50 and extends over both end portions of the laminated body 50. In other words, 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. Therefore, the core material 60 has an asymmetrical layer structure even if it is centered on either side of the stacking direction of the laminated body 50. With such a configuration, the laminated body 50 can be stabilized to impart a desired three-dimensional shape, such as a desired three-dimensional curved shape.

The exterior materials 71 and 72 mainly function as a layer that imparts a cushioning property to the shield member 40. That is, the external materials 71, 72 disposed at the position sandwiching the core material 60 having a higher strength serve the outer material 96 of the conventional protective member 100 shown in FIG. As an example, the external materials 71 and 72 can be formed as a urethane layer having a certain volume and exhibiting a desired cushioning property.

The table cloths 73, 75 constitute the outermost layer of the laminated body 50, which may be in contact with the infant sitting in the stroller or the protector of the infant. Therefore, the table cloths 73 and 75 can be constituted by a cloth material having a good touch or a cloth material which is easily decontaminated.

The bonding layers 75, 76, 77 and the bonding layer 66 in the core material 60 are layers composed of a thermoplastic adhesive, and function as a layer for welding adjacent layers. The bonding layers 75, 76, 77, 66 may 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, and 66.

As an example, the laminated body 50 composed of the above configuration can be produced extremely easily by the hot press processing shown in Fig. 6 .

In the hot press processing shown in Fig. 6, first, the above-described order is employed, and the laminates constitute the materials (cloth materials, materials) of the respective layers of the laminated body 50. Next, the molds 81 and 82 are pressed against the molds 81 and 82 in a shape corresponding to the shape to be applied to the laminated body 50, and the accumulated material group is pressed from both sides. At this time, the molds 81 and 82 are heated to a temperature equal to or higher than the temperature at which the material of each layer of the layered body 50 is softened. Thereby, the materials constituting the respective layers of the laminated body 50 are welded to each other. At the same time, the materials constituting each layer of the laminated body 50, in particular, the first thermal adhesive fiber assembly 61, the second thermal adhesive fiber assembly 62, and the third thermal adhesive fiber assembly 63 correspond to the molds 81 and 82. The shape of the cavity is deformed. Next, the laminate 50 can be obtained by trimming as needed.

The first member 56 is fixed to one end portion 56a of the stroller body 11 as a pressing edge portion 51, and the other end portion 56b of the first member 56 coupled to the coupling member 58 is also formed as a pressing edge portion 51. The first member 56 is formed between the first end portion 56a and the second end portion 56b, and can be configured in the same manner as the portion constituting the shield portion 40b of the laminated body 50. The first member 56 of this type can be stably fixed to the stroller body 11 and the coupling device 58.

Further, in the example shown in Fig. 7, the second member 57 is fixed to one end portion 57a of the stroller body 11 as a pressing edge portion 51, and the other end portion 57b of the second member 57 connected to the coupling member 58 is also It is formed as the press edge portion 51. Further, the second member 57 is formed between the first end portion 57a and the second end portion 57b, and can be configured in the same manner as the portion constituting the shield portion 40b of the laminated body 50, or the first end portion 57a and the first end portion 57a The two end portions 57b may be configured as the pressure edge portion 51 in the same manner. The second member 57 of this type can be stably fixed to the stroller body 11 and the coupling device 58.

Further, the structure of the stroller body 11 of the stroller 10 described in the above embodiment is merely an example. For example, the frame portion 15 may be configured to be unfoldable. Alternatively, the stroller disclosed in Japanese Laid-Open Patent Publication No. 2011-148454 is folded in the front-rear direction to be miniaturized, and further folded so as to be downsized in the width direction, so that the stroller body 11 of the stroller 10 can be constructed. Specifically, the member extending in the width direction of the stroller body 11, that is, the upper portion of the grip 13, the pedal 11 and the rear connecting member 19 have hinges (bending points) so that the members can be in the front-rear direction as described above.
