To shown in Figure 4, the open-close lid S of embodiment 1 is provided with the support 10 that alongst is provided for supporting the load that is applied to open-close lid S with arranging, two supports 10 be attached at the articulated section 20 that the mode between the adjacent support 10 forms and be separately positioned on the end 10A place relative with guide rail L1 in each support 10 and the sliding supporting part 30,30 at another end 10B place relative with another guide rail L2 in each support 10 such as Fig. 1.And, the open-close lid S of embodiment 1 for the support 10, articulated section 20 and the sliding supporting part 30 that consist of open-close lid S by one type shaped material by the integrally formed formed parts of injection moulding mould.As shaped material, preferably adopt synthetic resin, for example hard polyethylene (PE) and polypropylene (PP), rather than thermoplastic elastomer.
In the open-close lid S of embodiment 1, amount to 18 supports 10 and alongst arrange the ground setting, and form symmetrically along Width.Shown in Fig. 1 (a) and Fig. 2 (b), each support 10 forms elongated shape to be suitable for the length in two gaps between guide rail L1, the L2 along Width, and forms from the articulated section 20 towards the outstanding shape of the dorsal part of open-close lid S.Each support 10 be provided with the front outside plate that consists of open-close lid S board 12, along the first beam section 14 that the Width of open-close lid S extends, along the length direction of open-close lid S spaced apart with the first beam section 14 and parallel with the first beam section 14 the second beam section 16 and with the first beam section 14 and the second beam section 16 interconnected a plurality of connecting portions 18.Each connecting portion 18 is arranged between the first beam section 14 and the second beam section 16 with each predetermined gap along Width, and comprises that the support 10 of the first beam section 14, the second beam section 16 and each connecting portion 18 is configured to be limited with the so-called ladder shape rib structure in space between the first beam section 14 and the second beam section 16.
Shown in Fig. 2 (b) and Fig. 3 (b), the first beam section 14 and the second beam section 16 form symmetric shape along the length direction of open-close lid S, and be designed to the height setting of thickness direction must be larger than the width of length direction.And, shown in Fig. 1 (b) and Fig. 3 (b), in the first beam section 14 and the second beam section 16, the width of length direction is 20 sides (outside plate 12 sides) maximum (G1) in the articulated section, and along with becoming minimum (G2) away from articulated section 20 diminishes gradually at the end relative with articulated section 20.And, the first beam section 14 and the second beam section 16 form, when being divided into four moieties for convenience's sake and along Width, height in the part corresponding with two centre portions is maximum (H1), and the height at end 10A of support 10 and 10B place, another end is minimum (H2).In addition, the part towards an end 10A in the first beam section 14 and the second beam section 16 forms tilted shape, so that along with diminishing highly gradually near an end 10A from central authorities.In addition, form tilted shape towards the part of another end 10B, so that along with diminishing highly gradually during near another end 10B from central authorities.Thereby, the rigidity of guaranteeing and having the rigidity in the situation of animi resin to be equal at the space-filling between two beam sections 14 and 16 at the support 10 as rib structure that is limited with the space between the first beam section 14 and the second beam section 16, even so that from the top to the pars intermedia applied load of Width, the also flexure deformation of unlikely generation Width or torsional deflection.
Shown in Fig. 1 (b) and Fig. 3 (b), the width that each support 10 that comprises the first beam section 14 and the second beam section 16 forms length direction is 20 sides (outside plate 12 sides) maximum (W1) in the articulated section.And it forms along with away from articulated section 20, and the width of length direction diminishes gradually, and becomes minimum (W2) at the end relative with articulated section 20.That is to say that support 10 to be forming towards the outstanding mode of the dorsal part of open-close lid S, the shape of observing from the outside of the Width of open-close lid S is along with forming trapezoidal shape away from articulated section 20 is tapered.
To shown in Figure 3, articulated section 20 forms with support 10 alongst adjacent one another are, 10 board 12, connects each support 10 with the position in the front of facing thickness direction transversely arrangedly such as Fig. 1.In addition, articulated section 20 forms thinner than support 10, to allow resilient flexibility distortion or flexural deformation.And, articulated section 20 be designed to dorsal part at positive isolated support 10 with it become approach and the second beam section 16 of the first beam section 14 of a support 10 adjacent one another are and another support 10 realize contacting with each other before deformable.As mentioned above, the gap that clips between two supports 10 adjacent one another are of articulated section 20 forms trapezoidal shape, and therefore under the flat condition of open-close lid S, 20 sides are the narrowest in the articulated section, and along with becoming gradually large away from articulated section 20.The thickness setting of articulated section 20 is about 0.5mm.Therefore, it is designed to, even it is formed by the shaped material with the hard synthetic resin that needs rigidity, before adjacent support 10,10 is realized contacting with each other, resilient flexibility distortion or flexural deformation also can be possible, and in addition, even when before adjacent support 10,10 is being realized contacting with each other, being bent, do not occur because the fracture that plastic deformation causes yet.
Next, with reference to Fig. 1 each sliding supporting part 30 that is arranged on an end 10A and 10B place, another end along the Width of each support 10 is described to Fig. 3.Be arranged on the sliding supporting part 30 of an end 10A of each support 10 and the sliding supporting part 30 that is arranged on 10B place, another end and form symmetrically along Width, and so will distribute identical reference marker to same section.Each sliding supporting part 30 is arranged on than the position of backrest side more, articulated section 20 along thickness direction, and is provided with the first abutting part 32 and is set to alongst and the first abutting part 32 isolated the second abutting parts 34.Each first abutting part 32 forms in the mode that the end horizontal of the first beam section 14 from support 10 ground stretches out, being positioned on the same axis along Width, and being provided with the arm 32A of the end that is connected to the first beam section 14 and being formed on the butt protrusion 32B of the end of arm 32A.Shown in Fig. 3 (a) and Fig. 3 (b), when alongst observing, butt protrusion 32B forms round-shaped around the axis J2 that extends along its length.And two end faces of the length direction of butt protrusion 32B form aspect, and its outer peripheral face forms curved shape in the mode that bulges, and allow them to reach diameter in the slot part 114 of guide rail L1, L2 so that they form to have.In addition, butt protrusion 32B is designed to, and outer peripheral face can carry out contacting with each of bottom surface 114A, the upper surface 114B of slot part 114 and side 114C.The longitudinal cross-section of arm 32A is shaped as about rectangle, and the size of the thickness direction of arm 32A is larger with the connecting portion place of the first beam section 14, so that for the first beam section 14, the flexure deformation of length direction and thickness direction occurs unlikely.
And the second abutting part 34 of each sliding supporting part 30 alongst forms the shape with the first abutting part 32 symmetries, and is provided with the arm 34A and the butt protrusion 34B that is formed on the end of arm 34A of the end that is connected to the second beam section 16.Each second abutting part 34 forms in the mode that the end horizontal of the second beam section 16 from support 10 ground stretches out, being positioned on the same axis along Width, and being provided with the arm 34A of the end that is connected to the second beam section 16 and being formed on the butt protrusion 34B of the end of arm 34A.Shown in Fig. 3 (a) and Fig. 3 (b), when alongst observing, butt protrusion 34B forms round-shaped around the axis J2 that extends along its length.And two end faces of the length direction of butt protrusion 34B form aspect, and its outer peripheral face forms curved shape in the mode that bulges, and allow them to reach diameter in the slot part 114 of guide rail L1, L2 so that they form to have.In addition, butt protrusion 34B is designed to, and outer peripheral face can carry out contacting with each of bottom surface 114A, upper surface 114B and side 114C.The longitudinal cross-section of the arm 34A of the second beam section 34 is shaped as about rectangle, and the size of the thickness direction of arm 34A is larger with the connecting portion place of the second beam section 16, so that for the second beam section 16, the flexure deformation of length direction and thickness direction occurs unlikely.
Shown in Fig. 3 (b), each sliding supporting part 30 and the trapezoidal shape that is formed with the support 10 of sliding supporting part 30 as one man form from the articulated section 20 sides towards the tapered shape of a side away from articulated section 20.That is to say that the inclination outer wall away from the part of articulated section 20 and the first beam section 14 of support 10 on the first abutting part 32 of sliding supporting part 30 end face relative with the second abutting part 34 as one man forms tilted shape.Similarly, the inclination outer wall away from the part of articulated section 20 and the second beam section 16 of support 10 on the end face that the second abutting part 34 of sliding supporting part 30 is relative with the first abutting part 32 as one man forms tilted shape.Thus, under the flat condition of open-close lid S, be arranged at the first abutting part 32 of a sliding supporting part 30 in the support 10 and be arranged between the second abutting part 34 of the sliding supporting part 30 in another support 10 adjacent one another are the gap away from a side of articulated section 20 than 20 sides are large in the articulated section.Thereby, in each sliding supporting part 30, even the gap between the first abutting part 32 and the second abutting part 34 is alongst set greatlyr, when adjacent support 10,10 since the elastic deformation of articulated section 20 and posture displacement near the time, prevented that also adjacent sliding supporting part 30,30 the first abutting part 32 and the second abutting part 34 from contacting with each other.
And, shown in Fig. 3 (a) and Fig. 3 (b), be provided with at the place, two ends of an end 10A and another end 10B sliding supporting part 30, each support 10 of 30 by four-point supporting by pair of guide rails L1, L2 supporting, four-point supporting is provided by the first abutting part 32 of a sliding supporting part 30 and the first abutting part 32 and the second abutting part 34 these four abutting parts of the second abutting part 34 and another sliding supporting part 30.That is to say that contact point P3, the P4 of the bottom surface 114A of the slot part 114 among contact point P1, the P2 of the bottom surface 114A of the slot part 114 among each abutting part 32 of a sliding supporting part 30, guide rail L1 of 34 butts and each abutting part 32 of another sliding supporting part 30, another guide rail of the 34 butts L2 has the relation that forms the line B that extends with quadrangle form.
Thereby, when from just when board 12 applied load, each the first abutting part 32 in each sliding supporting part 30 and four abutting part butt pair of guide rails L1, L2 of each the second abutting part 34, thereby prevented that this allows stably to support each support 10 around the rotation displacement of the axis J1 of broad ways extension.If each the first abutting part 32 of each sliding supporting part 30 and abutting part butt pair of guide rails L1, the L2 more than at least three that amount to four abutting parts of each the second abutting part 34, thereby prevented that then rotation displacement from allowing support 10 is stably supported.
In the open-close lid S of embodiment 1, be provided with at the board 12 as the support 10 of the front side of floor bracket FC and project upwards and along the grip part 46 that Width extends, this grip part 46 has the size approximately identical with the size of the length direction of support 10.Thereby, grip the slide that grip part 46 allows easily to carry out open-close lid S with the finger tip.
In the open-close lid S of the above embodiments 1, be arranged on first abutting part 32 of each sliding supporting part 30 at 10A place, an end of each support 10 and the second abutting part 34 reach respectively be arranged on a guide rail L1 in the bracket main body 100 slot part 114 to engage.And, be arranged in first abutting part 32 of each sliding supporting part 30 at 10B place, another end of each support 10 and the slot part 114 that the second abutting part 34 reaches respectively another guide rail L2 to engage.Allow thus open-close lid S to be configured in slidably in the bracket main body 100.When open-close lid S with in the face of the mode of the upper opening 104 of article container section 102 when slide in the place ahead of bracket main body 100, the sliding supporting part 30,30 of each support 10 becomes linear portion 110 places that are positioned at each guide rail L1, L2, so that the flat condition of picture one flat plate to be provided, this allows to cover fully upper opening 104(referring to Fig. 4).
In addition, under the flat condition that the upper opening 104 of article container section 104 is covered fully, even by upwards towards the front on placing articles or passenger's arm, place hand etc. thereon and apply to a certain degree load from the top to it, the open-close lid S of embodiment 1 also can suitably keep flat condition.That is to say, each support 10 that has received load along thickness direction from the front can stably keep its posture, and not having rotation displacement, this is because the abutting part more than at least three that amounts to four abutting parts of the first abutting part 32 of the first abutting part 32 of a sliding supporting part 30 and the second abutting part 34 and another sliding supporting part 30 and the second abutting part 34 is realized the bottom surface 114A of the slot part 114 among butt each guide rail L1, L2.In addition, each support 10 consists of and comprises the rib structure of the first beam section 14, the second beam section 16 and connecting portion 18, and has rigidity, even so that from the top applied load of board 12, also can reduce flexure deformation and the torsional deflection of Width.
On the other hand, as open-close lid S during towards the rear Slideslip of bracket main body 100, the support 10 of the rear side of length direction is designed at first move to the curve 112 of each guide rail L1, L2.When support 10 moved to the curve 112 of each guide rail L1, L2, the butt protrusion 34b that is arranged on the butt protrusion 32b of the first abutting part 32 of each sliding supporting part 30 of support 10 and the second abutting part 34 became the upper surface 114B of the slot part of butt each guide rail L1, L2.Thus, in the adjacent support 10,10 of the curve 112 that moves to each guide rail L1, L2, the articulated section 20 between two supports 10,10 flexibly is out of shape, and this allows another support 10 with respect to a support 10 displacement postures.Then, shown in Fig. 1 (b), open-close lid S has the case of bending of the curvature identical with the curvature of the curve 112 of each guide rail L1, L2 owing to the elastic deformation of each articulated section 20 is deformed into.
Like this, in the open-close lid S of embodiment 1, when from the front applied load of open-close lid S, each support 10 that consists of open-close lid S amounts to four at each first abutting part 32 and each second abutting part 34() the abutting part place more than three supported by pair of guide rails L1, L2, wherein for each the sliding supporting part 30,30 that is arranged at an end 10A and another end 10B two abutting parts are set, so that support 10 is not shifted rotatably around the axis J1 that broad ways is extended.And, the middle ground that the first abutting part 32 of sliding supporting part 30 and the second abutting part 34 clip the length direction of support 10 is arranged on an end 10A and another end 10B, even to support 10 applied loads, the axis J1 that support 10 also unlikely extends around broad ways is shifted rotatably so that in the position (position of the more close articulated section 20 of ratio central authorities) from central offset.That is to say that in the open-close lid S of embodiment 1, when from the front during at each support 10 applied load, stress unlikely concentrates on the articulated section 20 of connection support part 10, thereby more unfertile land forms articulated section 20.Thus, it is thin that articulated section 20 namely uses the shaped material identical with the shaped material that is used to form support 10 and each sliding supporting part 30 to form, and also can have flexible.Thereby, can use identical animi resin be shaped integratedly support 10, articulated section 20 and sliding supporting part 30.That is to say, because for open-close lid S, can only with the next open-close lid S that in a step, is shaped integratedly of a kind of shaped material, so material cost can be cheap, and can reduce the man-hour for shaping operation, thereby keep productive costs lower.
In addition, as mentioned above, open-close lid S is shaped integratedly by a kind of shaped material, and therefore this prevent that support 10 and articulated section 20 break away from from the boundary portion between them.Equally, each that also prevents support 10 and sliding supporting part 30 breaks away from from the boundary portion between them, thereby do not have the situation that can not use open-close lid S owing to break away from.
And, be arranged on sliding supporting part 30 first abutting parts 32 and articulated section 20 face relative to each other that clips that is arranged on sliding supporting part 30 second abutting parts 34 of another support 10 of a support 10, with along with away from articulated section 20 along direction of slip mutually away from mode form, one of them support 10 is adjacent one another are with another support 10.Thereby even the gap of direction of slip is set greatlyr, when open-close lid S was deformed into case of bending, the first abutting part 32 and the second abutting part 34 in the sliding supporting part 30 can not contact with each other yet, thereby do not prevent that open-close lid is deformed into case of bending.Therefore in addition, the first abutting part 32 in the sliding supporting part 30 and the gap of the direction of slip between the second abutting part 34 can be larger, even this when applied load under the flat condition of open-close lid S, also improves the stability of support 10.
And, each support 10 consists of the rib structure that has together the first beam section 10 and the second beam section 10 of alongst arranging and be used for linking two beam sections 14,16 connecting portion 18, and if therefore can have the rigidity that is subject to the load that can expect then unlikely causes flexure deformation or torsional deflection.Especially, the height design of the middle body of the first beam section 14 of each support 10 and the Width of the second beam section 16 makes it possible to suitably receive the load that is applied to open-close lid S from the front in the in check situation of flexure deformation for setting greatlyr.In addition, each support 10 forms the size of length direction along with through-thickness and articulated section 20 spaced apart and tapered trapezoidal shapes, thereby can not prevent that open-close lid S is owing to the distortion of articulated section 20 is deformed into case of bending.
And, each sliding supporting part 30, the first abutting part 32 of 30 and the friction drag between the second abutting part 34 and each guide rail L1, the L2 are restricted to lower, and therefore open-close lid S can move slidably with less power, thereby can improve the operability of opening and closing open-close lid S.
In addition, because be limited with the space between the first beam section 14 of each support 10 and the second beam section 16, reduce so can realize the weight of open-close lid S, and the use amount of shaped material is also less, this can keep productive costs lower.And, because the use amount of shaped material is less, so can also prevent when being shaped the position corresponding with support 10 on the outside face of open-close lid S the defective of shaping indenture occurs.
