Description

  The present invention relates to a hinge used for an opening / closing mechanism of various articles such as a door and a lid.

Conventionally, metal hinges are used for opening and closing mechanisms of various articles such as doors and lids. In such a general hinge, a shaft cylinder part including the axis of the rotating shaft is often formed (for example, Patent Document 1). In such a hinge, for example, both the blades of the hinge are configured to be rotatable with respect to the rotation axis by rotating the shaft tube portion.
In the case of a metal hinge, in a state in which both wings of the hinge are overlapped, that is, in a closed state of the hinge, the diameter of the shaft tube portion is generally formed larger than the thickness of the overlapped both wings.

Here, the first component 2 is attached to the side surface 50 a of the door 50 to be opened and closed and the side surface 52 a of the frame body 52 through the fastening member 40 inserted into the central through hole 35. At this time, after the rotation of the screw portion 41 of the fastening member 40 (FIG. 7) stops, the fastening reinforcement portion 42 further rotates and is pushed into the screw portion 41 side, and the circular protrusion 45 is around the central through hole 35. It engages with a recess 39 (FIG. 6) formed in the. In addition, illustration of the recessed part 39 is abbreviate | omitted in FIG.

  Next, as shown in FIG. 8B, the second component 3 is attached to the first component 2 and the object. Here, in the rotation axis direction X, the outer edge 2c of the first component 2 and the outer edge 3c of the second component 3 are aligned, and the first member 2 is inserted through the fastening member 40 inserted into the end through hole 34. The two constituent parts 3 are attached to the door 50 and the frame body 52 together with the first constituent part 2. At this time, as shown in FIG. 2, the entire surface of the second intermediate reinforcing portion 18 is in contact with the first intermediate reinforcing portion 7. Since the width L3 of the first component 2 is larger than the width L4 of the second component 3, the outer edges 2c and 3c of the first component 2 and the second component 3 are fixed. The second sheet-like portion 14 is pulled, and the first sheet-like portion 5 is bent at the bent portion 8, and the maximum value of the rotation angle θ1 of the hinge is determined. That is, by attaching the second component 3, the hinge 1 is prevented from opening beyond a predetermined angle. Thus, the 2nd structure part 3 has a function as a stopper.

  The closed state of the hinge 1 shown in FIG. 8 (b) is shown in FIG. 9 (a) and FIG. 9 (b). As shown in FIG. 9A, when the door 50 rotates in the closing direction F from the open position 55 indicated by the dotted line toward the door receiving portion 53 of the frame body 52, both ends 36a and 36b of the hinge 1 are accordingly moved. Approach. Then, as shown in FIG. 9B, the surfaces 17 e of the pair of second hinge reinforcing pieces 17 a and 17 b come into contact with each other, the hinge 1 is closed, and the door 50 is closed with respect to the frame body 52. At this time, the first sheet-like portion 5 is bent at the bent portion 8. As described above, in the hinge 1, the opening and closing operation of the hinge 1 is realized by bending the first sheet-like portion 5.

  Further, as the hinge 1 rotates in the closing direction F, the second sheet-like portion 14 is bent along the bending shaft portion 29. Since the bending shaft portion 29 protrudes toward the first sheet-like portion 5 in the open state, the bending shaft portion 29 is bent so as to approach the bending portion 8 when a rotational force in the closing direction F is applied. Will be. As a result, the third sheet-like portion 15 is extended. Accordingly, since the third sheet-like portion 15 and the adhesive layer 27 constituting the protruding portion 31 (FIG. 2B) are pulled radially outward, the protruding height of the protruding portion 31 is lowered in the closed state. Or zero.

  As described above, the rotation axis R of the hinge 1 is located on the first sheet-like portion 5. Since the hinge 1 is not provided with the shaft tube portion on the rotation axis R, the shaft tube portion is not exposed to the outside of the attachment target. 9A and 9B, in the closed state, the entire hinge 1 is accommodated between the side surface 50a of the door 50 and the side surface 52a of the frame body 52, and is located on the rotation axis R. The bent portion 8 does not protrude outside the door 50 and the frame body 52.

Next, a method for manufacturing the hinge 1 will be described.
The manufacturing method of the hinge 1 includes the steps of attaching the first hinge reinforcing part 6 and the first intermediate reinforcing part 7 to the first sheet-like part 5 to form the first component part 2, and the second hinge reinforcing part. A step of attaching the part 17 and the second intermediate reinforcing part 18 to the second sheet-like part 14 to form the second component part 3. The step of forming the second component part 3 includes the step of forming the third sheet-like part 15 of the second sheet-like part 14 in a state in which the second sheet-like part 14 is bent along the axis extending in the rotation axis direction X. It includes the step of forming the bending shaft portion 29 on the axis by spreading the second sheet-like portion 14 in the opening direction G with the third sheet-like portion 15 attached to the outside.

  Below, the step which produces | generates the 2nd structure part 3 is demonstrated in detail. As shown in FIG. 10A, the sheet-like carbon fiber material is cut into a predetermined size to form the second sheet-like portion 14. Further, the metal plate is cut into a predetermined size to form second intermediate reinforcing pieces 18a and 18b and second hinge reinforcing pieces 17a and 17b. In the second intermediate reinforcing pieces 18a and 18b and the second hinge reinforcing pieces 17a and 17b, honeycomb-shaped irregularities 37 and lateral grooves 38 are formed on the surface in contact with the second sheet-like portion 14 by pressing. Keep it.

  Next, the second intermediate reinforcing pieces 18a and 18b are arranged on one main surface 14a of the second sheet-like portion 14, and the second hinge reinforcing pieces 17a and 17b are arranged on the other main surface 14b. A resin functioning as an adhesive is applied to the second sheet-like portion 14. Next, the second sheet-like portion 14 is sandwiched between the second intermediate reinforcing pieces 18a and 18b and the second hinge reinforcing pieces 17a and 17b, and the second intermediate reinforcing pieces 18a and 18b and the second hinge reinforcing piece 17a are sandwiched. , 17b are pressure-bonded to the second sheet-like portion 14.

  Next, as shown in FIG. 10B, the second component 3 is bent at the center 56 in the width direction W so that both end portions 57 a and 57 b of the second component 3 approach each other. Then, as shown in FIG. 11C, the shaft core 30 is arranged at the center 56 on the main surface 14 a of the second sheet-like portion 14, and a resin such as epoxy is laminated to form the adhesive layer 27. . Thereby, the shaft core 30 is fixed to the adhesive layer 27, and the adhesive layer 27 including the shaft core 30 is laminated on the main surface 14 a of the second sheet-like portion 14.

Next, the sheet-like carbon fiber material is cut into a predetermined size to form the third sheet-like portion 15. At this time, as shown in FIG. 11C, the width dimension of the third sheet-like portion 15 is one second intermediate reinforcement on the adhesive layer 27 in a state where the second sheet-like portion 14 is bent. The dimension is set so as to cover from the inner edge 18d of the piece 18a to the inner edge 18d of the other second intermediate reinforcing piece 18b. Here, the third sheet-like part 15 is located outside the second sheet-like part 14. Therefore, the width dimension of the third sheet-like portion 15 is the width dimension of the second sheet-like portion 14 from the inner edge 18d of the second intermediate reinforcing piece 18a to the inner edge 18d of the second intermediate reinforcing piece 18b (that is, The width dimension L10) of the exposed region 25 of the second sheet-like portion 14 is larger.
The third sheet-like portion 15 is stuck on the adhesive layer 27. The third sheet-like portion 15 is bonded to the second sheet-like portion 14 by the adhesive layer 27.

  Next, as shown in FIG. 11 (d), both end portions 57 a and 57 b of the second component 3 are widened so that the main surface 14 b of the second sheet-like portion 14 is flush. Then, as described above, since the width dimension of the third sheet-like portion 15 is larger than the width dimension L10 of the exposed region 25 of the second sheet-like portion 14, the third sheet-like portion 15 is centered. At 56, it protrudes from the main surface 14 a of the second sheet-like portion 14 together with the shaft core 30. Thereby, the bending shaft part 29 which has the protrusion part 31 is formed. Since the bending shaft portion 29 protrudes from the main surface 14a of the second sheet-like portion 14, the bending shaft portion 29 moves in the protruding direction J when the hinge 1 is rotated in the closing direction F (FIG. 2A). Then, the second sheet-like portion 14 is folded.

The 1st structure part 2 is formed by the method similar to the manufacturing method of the 2nd structure part 3 demonstrated with reference to Fig.10 (a). That is, a resin functioning as an adhesive is applied to the first sheet-like portion 5, and the first hinge reinforcing portion 6 and the first intermediate reinforcing portion 7 are pressure-bonded.
In addition, a central through hole 35 and an end through hole 34 are formed in the first component 2, and an end through hole 34 is formed in the second component 3. At this time, in addition to the through holes 34 and 35, the side where the fastening member 40 is inserted around the end through hole 34 of the second hinge reinforcing portion 17 and the central through hole 35 of the first intermediate reinforcing portion 7. A recess 39 is formed on the surface of the substrate by pressing.

  In the present embodiment, in the manufacturing process of the hinge 1, the first sheet-like portion 5, the first hinge reinforcing portion 6, and the first intermediate reinforcing portion 7 have their respective length dimensions (rotation axis direction X). ) Is longer than the first component 2 to be finally formed. For example, a length of several meters is formed. And after crimping | bonding the 1st hinge reinforcement part 6 and the 1st intermediate reinforcement part 7 to the 1st sheet-like part 5, the 1st sheet-like part 5, the 1st hinge reinforcement part 6, and the 1st middle The reinforcing part 7 is simultaneously cut at a desired interval. Thereby, the some 1st structure part 2 is formed.

  The same applies to the second component 3, and in the manufacturing process of the second component 3 described with reference to FIGS. 10 and 11, the second sheet-shaped portion 14, the third sheet-shaped portion. 15. The length dimension of the 2nd intermediate | middle reinforcement part 18 and the 2nd hinge reinforcement part 17 is longer than the 2nd component part 3 finally formed. Then, the second component 3 shown in FIG. 11D is cut at a predetermined interval so as to have the same length as the corresponding first component 2. Thereby, a plurality of second constituent parts 3 are formed.

  The through holes 34 and 35 may be formed in a predetermined position before the cutting step, or the cut first component 2 and the cut second component 3 may be formed in the cut first component 2 and the cut second component 3. , Each may be formed.

  As described above, the hinge 1 according to the present embodiment is composed of a sheet-like fiber material and can be bent along the rotation axis R, and one of the first sheet-like parts 5. In the main surface 5a, a first hinge reinforcing portion 6 disposed so as to cover at least a part of the region excluding the region on the rotation axis R, and a sheet-like fiber material, the first sheet-like portion 5, the second sheet-like portion 14 disposed on the other principal surface 5 b side, the other principal surface 5 b of the first sheet-like portion 5, and one principal surface 14 a of the second sheet-like portion 14. The intermediate reinforcing portions 7 and 18 disposed between them and the second hinge reinforcing portion 17 disposed on the end portions 21a and 21b in the width direction W on the other main surface 14b of the second sheet-like portion 14 I have.

  Therefore, in the hinge 1, the opening / closing operation of the hinge 1 can be realized by bending the first sheet-like portion 5 while maintaining the strength of the hinge 1. Therefore, when the hinge 1 is attached, the shaft cylinder portion does not protrude to the outside and is not exposed. Therefore, according to the hinge 1 which concerns on this embodiment, it can suppress that a rotating shaft part protrudes from the surface of the articles | goods which attached the hinge, and can aim at the improvement of aesthetics and space saving.

  Moreover, since it is not necessary to process and form the shaft cylinder part which achieves a rotation mechanism, the formation process of the hinge 1 can be performed easily. In addition, for example, in the case of a conventional metal hinge, the rotation mechanism of the shaft tube portion is formed in accordance with the size of the hinge. Therefore, when the shaft tube portion is cut in the width direction, the rotation mechanism does not operate. There is a high possibility that On the other hand, in the hinge 1 according to the present embodiment, the opening / closing operation by bending the first sheet-like portion 5 is realized regardless of the position of the hinge 1 in the rotation axis direction X. Therefore, by forming the hinge 1 in a state longer than the length dimension of the hinge 1 finally formed (dimension in the rotation axis direction X), and then cutting it to a desired length, a plurality of hinges 1 are formed. A hinge 1 can be formed. Therefore, the forming process of the hinge 1 is further facilitated. Further, when the hinge 1 is attached, the hinge 1 can be cut in the width direction W in accordance with the size of the attachment location, and the length dimension of the hinge 1 can be adjusted.

  Further, the first sheet-like portion 5 and the second sheet-like portion 14 formed of the fiber material are reinforced by the first hinge reinforcing portion 6, the second hinge reinforcing portion 17, and the intermediate reinforcing portions 7 and 18. Therefore, the strength and durability of the hinge 1 can be increased.

  Moreover, in the hinge 1, the 1st structure part 2 and the 2nd structure part 3 are formed so that attachment or detachment is mutually possible. Therefore, since the 2nd structure part 3 can be attached after attaching the 1st structure part 2 to the attachment target object of the hinge 1, the attachment of the hinge 1 can be performed easily and firmly. On the other hand, when the first component 2 and the second component 3 are bonded in advance, it may be difficult to attach the portion where only the first component 2 is to be attached. For example, when the first component 2 and the second component 3 are bonded in advance when the first component 2 is attached via the central through hole 35 of the first component 2, The second sheet-like part 14 becomes in the way, making the attachment work difficult, and the risk of damaging the second sheet-like part 14 is also increased. However, according to the hinge 1, since only the 1st structure part 2 can be attached previously, attachment work can be performed easily. Further, since the attachment position of the first component 2 (for example, the formation position of the central through hole 35) can be determined without being limited to the positional relationship with the second component 3, the first The component 2 can be firmly attached to the object.

Moreover, since the 1st structure part 2 and the 2nd structure part 3 can be mutually attached or detached, the combination of the 1st structure part 2 and the 2nd structure part 3 according to the attachment target object of hinge 1 is possible. Can be adjusted. For example, a plurality of second components 3 having different width dimensions are prepared, and when the hinge 1 is attached, the second component 3 having a width corresponding to the desired maximum rotation angle of the attachment object is selected. Can be attached. Therefore, it becomes easy to adjust the maximum rotation angle of the hinge 1 according to the attachment object of the hinge 1.
In addition, when the hinge 1 is manufactured, the bonding process between the first component 2 and the second component 3 is not required, and therefore the hinge 1 can be manufactured more easily.

  In the hinge 1, the width dimensions of the first hinge reinforcing pieces 6a and 6b are the same as the width dimensions of the first intermediate reinforcing pieces 7a and 7b. Therefore, the first hinge reinforcing pieces 6a and 6b and the first intermediate reinforcing pieces 7a and 7b facing each other through the first sheet-like portion 5 can further increase the force for sandwiching the first sheet-like portion 5. it can. The width dimensions of the second hinge reinforcing pieces 17a and 17b are the same as the width dimensions of the second intermediate reinforcing pieces 18a and 18b. Therefore, the second hinge reinforcing pieces 17a and 17b and the second intermediate reinforcing pieces 18a and 18b facing each other through the second sheet-like portion 14 can further increase the force for sandwiching the second sheet-like portion 14. it can.

  As described above, when the hinge 1 is opened, the exposed second sheet-like portion 14 is pulled by the both end portions 36a and 36b of the hinge 1, so that the second hinge reinforcing pieces 17a and 17b have a radial direction. A bending force toward the outside is applied from the second sheet-like portion 14. In this regard, in the present embodiment, the second hinge reinforcing pieces 17a and 17b are configured such that the thickness dimensions of the second hinge reinforcing pieces 17a and 17b are larger than the thickness dimensions of the first hinge reinforcing pieces 6a and 6b. The strength of the hinge reinforcing pieces 17a and 17b can be increased.

  In the hinge 1, the width dimension L10 of the second sheet-like portion 14 from the inner edge 17d of one second hinge reinforcing piece 17a to the inner edge 17d of the other second hinge reinforcing piece 17b is one second hinge. The distance D is smaller than the distance D from the inner edge 17d of the reinforcing piece 17a to the inner edge 17d of the other second hinge reinforcing piece 17b via the rotation axis R. Therefore, the maximum rotation angle value of the rotation angle θ1 of the hinge 1 is less than 180 degrees, and the second sheet-like portion 14 can function as a stopper. Thus, for example, when the hinge 1 is used to open and close the door 50, the door 50 can be prevented from opening more than the maximum rotation angle of the hinge 1 without providing another member such as a door stopper on the floor surface or the like.

  Further, in the hinge 1, the width dimension L3 of the first sheet-like part 5 is larger than the width dimension L4 of the second sheet-like part 14. Therefore, when both the outer edges 5c and 14c in the width direction W of the first sheet-like part 5 and the second sheet-like part 14 are aligned, and the second component 3 is attached to the first component 2, The first sheet-like portion 5 is bent at a predetermined angle. Therefore, the 2nd sheet-like part 14 can be functioned as a stopper. Therefore, as described above, it is not necessary to provide another member such as a door stopper.

  In the hinge 1, a bending shaft portion 29 that protrudes from the main surface 14 a and extends in the rotation axis direction X is formed on one main surface 14 a of the second sheet-like portion 14. Thereby, when the hinge 1 is rotated in the closing direction F, the second sheet-like portion 14 can be folded along the folding shaft portion 29. Since the bending shaft portion 29 protrudes from the main surface 14a of the second sheet-like portion 14, when the rotational force is applied to the second sheet-like portion 14, the bending shaft portion 29 has a diameter rather than a radially outer side. The second sheet-like portion 14 is folded so as to go inward in the direction. Therefore, it is possible to avoid problems such as the second sheet-like portion 14 being folded in the opposite direction and being sandwiched between the pair of second hinge reinforcing pieces 17a and 17b.

  Further, an axial core 30 extending in the rotation axis direction X is attached to the bending shaft portion 29. Thereby, the intensity | strength in the bending part 8 of the 2nd sheet-like part 14 can be raised.

  In the hinge 1 according to the present embodiment, the third sheet-like part 15 is laminated on the main surface 14a of the second sheet-like part 14, and the second sheet-like part 14 and the third sheet-like part 15 are A shaft core 30 extending in the rotation axis direction X is attached therebetween. Thereby, the exposure area | region 25 of the 2nd sheet-like part 14 is reinforced, and durability of the 2nd sheet-like part 14 can be improved. Further, since the shaft core 30 is not exposed, the shaft core 30 can be prevented from peeling off.

  Moreover, in the hinge 1, the 1st hinge reinforcement part 6, the 2nd hinge reinforcement part 17, and the intermediate reinforcement parts 7 and 18 are formed in plate shape, and the 1st sheet-like part 5 or 2nd Concavities and convexities 37 are formed on the surface in contact with the sheet-like portion 14. Thereby, the frictional force between the 1st hinge part 6, the 2nd hinge reinforcement part 17, and the intermediate reinforcement parts 7 and 18 and the 1st sheet-like part 5 or the 2nd sheet-like part 14 increases. be able to. Therefore, the first hinge part 6, the second hinge reinforcement part 17, the intermediate reinforcement parts 7, 18 and the first sheet-like part 5 or the second sheet-like part 14 are more firmly joined. can do.

  In the hinge 1 according to the present embodiment, a lateral groove 38 extending in the width direction W is formed in the first hinge reinforcing portion 6, the second hinge reinforcing portion 17, and the intermediate reinforcing portions 7 and 18. Thereby, with respect to the bending force applied to each inner edge extending in the rotation axis direction X of the first hinge reinforcing portion 6, the second hinge reinforcing portion 17, and the intermediate reinforcing portions 7, 18, the first hinge reinforcing portion 6, The strength of the second hinge reinforcing portion 17 and the intermediate reinforcing portions 7 and 18 can be further increased. Accordingly, even when a bending force generated by pulling the first sheet-like part 5 or the second sheet-like part 14 is applied, the first hinge reinforcing part 6 and the second hinge reinforcing part 17 are applied. And deformation of the intermediate reinforcing part can be prevented.

  In hinge 1, it attaches to the 1st sheet-like part 5, the 2nd sheet-like part 14, the 1st hinge reinforcement part 6, the 2nd hinge reinforcement part 17, and the intermediate reinforcement parts 7 and 18. Through holes 34 and 35 are formed, and a recess 39 is formed around the through hole 34 formed in the second hinge reinforcing portion 17. Thereby, in addition to inserting the fastening member 40 into the through hole, the circular protrusion 45 of the fastening member 40 can be engaged with the recess 39, so that the attachment strength of the hinge 1 can be further increased.

  Further, as described above, in the threaded portion 41 of the fastening member 40, the width dimension L11 of the thread 44 in the radial direction is the same width on the upper surface 44a of the thread 44 and the lower surface 44b of the thread 44. Therefore, the screw portion 41 is less likely to be removed and the attachment strength of the hinge 1 is further increased as compared with a screw screw or the like in which the diameter of the screw thread gradually decreases from the upper surface of the screw thread toward the tip of the screw. Can do.

  In this embodiment, the 1st hinge reinforcement part 6, the 2nd hinge reinforcement part 17, and the intermediate reinforcement parts 7 and 18 are attached to the 1st sheet-like part 5 or the 2nd sheet-like part 14 by crimping | compression-bonding. By performing such pressure bonding, the thickness of the resin applied to the carbon fiber material can be further reduced. Therefore, since the buckling of the resin due to the tensile force can be prevented in the first sheet-like part 5 and the second sheet-like part 14, the first sheet-like part 5 and the second sheet-like part 14 are peeled off. The prevention effect can be enhanced.

  In the above embodiment, a carbon fiber material is used as the fiber material. Since carbon fiber is excellent in tensile strength and fatigue characteristics, the durability of the hinge 1 can be increased and the thickness dimension of the hinge 1 can be reduced.

  In addition, as described above, since the carbon fiber sheet knitted in both the vertical and horizontal directions and the diagonal 45 degrees is used for the first sheet-like part 5 and the second sheet-like part 14, durability against tensile force is provided. Can be increased. For example, even when the hinge 1 is attached so that the rotation axis R is positioned in the vertical direction like a general door, it is durable against a downward tensile force caused by the weight of the object to be attached. Can be increased. Therefore, it is possible to prevent the object to which the hinge 1 is attached from shifting downward.
