Description

  TECHNICAL FIELD The present invention relates to a highly durable general-purpose hinge having the same appearance as a commercially available metal hinge, and a brake-rotating general-purpose hinge attached to furniture, joinery, daily necessities, keyboard instruments, etc. having a rotating body such as a lid or an opening / closing door. About.

  There are many existing furniture, joinery, daily necessities, containers, electrical products, keyboard instruments or their accessories that have an opening / closing member such as a lid or window. For example, a keyboard lid as shown in FIG. A grand piano 100 having an open / close lid 102, a writing desk having an open / close front plate, a table with an open / close-type end plate, a jewelry box with a lid and a music box. In these products, a commercially available metal hinge 104 is attached to the opening / closing member, and the opening / closing member is configured to be rotatable by the hinge.

  In a conventional metal hinge, two leaves are rotatably connected to each other by a pivot inserted into a series of tube portions, and one of the leaves is fixed to a lid and the other is fixed to a main body with wood screws or nails. This kind of hinge cannot be stopped at an arbitrary opening angle if the load of the lid is applied to the leaf, and is fully opened when the hand is released with the lid partially opened, or the original So close. This opening / closing operation is performed shockingly, and the user may injure by stuffing his / her finger into the lid or may damage the lid or the main body.

Examples of the metal hinge for rotating the rotation include Japanese Utility Model Laid-Open No. 53-140857, Japanese Patent Application Laid-Open No. 9-217545, Japanese Patent Application Laid-Open No. 2003-248527, and the like filed by the present inventors. By attaching these hinges, lids such as furniture and joinery can be opened and closed, and the lid can be kept stationary at an arbitrary opening angle, and does not rotate slightly at the start of opening and closing. When these hinges are attached, the opening / closing operation is not shocked even when the load of the movable plate is applied to the leaf, and it is possible to prevent the user from stuffing the movable plate with fingers or damaging the main body.
Japanese Utility Model Publication No. 53-140857 JP-A-9-217545 JP 2003-248527 A

  Regarding the conventional metal hinge, the hinge disclosed in Japanese Utility Model Laid-Open No. 53-140857 tightens the rotating shaft with a metal member, so that the rotating shaft is not sufficiently braked, and an unpleasant metal sound is generated or durability is increased. There is a problem of lack of sex. On the other hand, the hinge disclosed in Japanese Patent Application Laid-Open No. 9-217545 or Japanese Patent Application Laid-Open No. 2003-248527 has sufficient braking force and durability, but has a braking member, a holding bracket and a tightening screw in the intermediate barrel portion. It is a protrusion from the leaf. Due to the presence of such protrusions, the closing angle of the hinge is somewhat limited, and there are some evaluations that the aesthetic appearance is impaired when the hinge attachment point is visible.

  The present invention has been proposed to improve the above-described problems associated with conventional metal hinges, and further improves the hinges attached to furniture, joinery, containers, etc., and allows the lid to stand still at any opening angle. However, it proposes a hinge that is similar in appearance to the conventional one. That is, the object of the present invention is to attach the rotating body to furniture, joinery, containers, etc. having a rotating body such as a lid or an opening / closing door, so that the rotating body can be stopped at an arbitrary opening angle and there are few parts and is relatively inexpensive. It is to provide a universal hinge. Another object of the present invention is to provide a general-purpose hinge that is highly durable and can be further miniaturized by simplifying the structure when incorporated in a notebook computer or monitor stand having a rotating body.

  A general-purpose hinge according to the present invention includes a first leaf having at least one intermediate barrel portion, a second leaf having at least both end barrel portions, and a plastic brake fitted into the intermediate barrel portion and rotatable with the first leaf. The sleeve includes a sleeve and a pivot that is fitted into the end barrel portion and is rotatable with the second leaf. By press-fitting a part of the pivot into the brake sleeve, the outer peripheral surface of the pivot and the inner peripheral surface of the brake sleeve become friction surfaces, and both the leaves can be stopped at an arbitrary opening angle.

  More specifically, the general-purpose hinge according to the present invention includes a first leaf having an intermediate barrel portion, a second leaf having end barrel portions, and both ends inserted from both end surfaces of the intermediate barrel portion and the first leaf. You may provide two plastic brake sleeves which can rotate, and two pivots which are inserted from the outer end surfaces of the barrel portions on both ends and can rotate together with the second leaf. In this case, both rear portions of both pivots are located in the intermediate barrel portion, and both rear portions are press-fitted into the brake sleeve, whereby the outer peripheral surface of the pivot and the inner peripheral surface of the brake sleeve become friction surfaces, Both leaves can be stationary at any opening angle.

  In the general-purpose hinge according to the present invention, it is preferable that the brake sleeve has a flange portion, and the flange portion is positioned between the end side barrel portion and the intermediate barrel portion. If desired, a notch is provided in the flange portion of the brake sleeve, and a protrusion is formed on the end surface of the intermediate barrel portion. The notch is fitted to the protrusion of the intermediate barrel portion, so that the brake sleeve is fitted to the first leaf. Rotate with. Further, serration processing is performed on the peripheral surface of the head portion of the pivot, and the pivot rotates together with the second leaf by driving this grooved head portion into the end side barrel of the second leaf.

  The present invention will be described with reference to the drawings. A general-purpose hinge 1 (FIG. 1) according to the present invention has one leaf 3 or 5 attached to a rotating body such as an open / close lid 102, similarly to the conventional metal hinge 104 shown in FIG. Attach the other leaf 5 or 3 to the piano body. In this specification, the first leaf and the second leaf are simply used to distinguish two leaves for explanation, the second leaf has an intermediate barrel portion, and the first leaf is a barrel on both ends. Of course, it is also possible to have a part.

  1 to 4, the general-purpose hinge of the present invention includes a case where the first leaf 3 having one intermediate barrel portion 7 and the second leaf 5 having two end-side barrel portions 8 and 10 are provided. Explains. The present invention is also applicable to the case where the number of first leaves is two or three or more and the number of second leaves is three or four or more. In this case, the two braking sleeves 16 are disposed on the end barrel portion. Fits into adjacent barrels. For example, in the modification shown in FIG. 9, if the first leaf has two barrel portions and the second leaf has three barrel portions, the two pivots and the brake sleeve can be used symmetrically, so that the balance is achieved. Will be better.

  The plastic braking sleeve 16 is preferably made of a wear-resistant plastic colored in an arbitrary color depending on the application. The brake sleeve 16 has a cylindrical shape as shown in FIG. 5, and the inner peripheral surface of the sleeve can slide on the outer peripheral surface of the rear portion 30 of the pivot 24 after assembly, and the outer peripheral surface of the sleeve rear portion 20 is an intermediate barrel. Close contact with the inner peripheral surface of the portion 7. For example, the brake sleeve 16 and the intermediate barrel portion 7 may be integrated by, for example, forming a vertical protrusion on the sleeve rear portion 20 in addition to the combination of the protrusion 14 (FIG. 3) and the notch 22 (FIG. 5 (1)). The longitudinal groove for fitting the protrusion may be provided from the end surface of the intermediate barrel portion 7, or the lower end surface of the sleeve flange portion 18 and the end surface of the intermediate barrel portion 7 may be both formed into a wave shape.

And a rear portion 30 to be press-fitted. The grooved head portion 26 is formed by serration processing by a die or rolling, and is driven into the end side barrel portion 8 at the time of assembly to be integrated with the barrel portion. In the pivot 24, the grooved head portion 26 is driven into the end barrel portion 8 to be integrated. Instead of this grooved head, for example, it is integrated by spline processing, or the pivot head part is formed in a deformed cross section such as hexagon, ellipse or semicircle, and molding or dent according to the shape of the deformed cross section May be applied to the end-side barrel portion 8 or may be fixed with an adhesive by forming a screw alignment structure or a key and a key groove.

  The general-purpose hinge according to the present invention can hold a rotating body such as a lid or an open / close door at an arbitrary rotational position, has high durability, and has the same appearance as a conventional metal hinge. For this reason, the general-purpose hinge of the present invention can be used as it is instead of the place where the conventional metal hinge is attached, and it is not evaluated that the place is detrimental to human eyes, and the closing angle of the hinge is also It is exactly the same as a conventional metal hinge.

  The general-purpose hinge of the present invention surrounds the outer peripheral surface of the brake sleeve by the intermediate barrel portion of the first leaf, so that the opening / closing operation of the rotating body is kept constant even when used for a long time. In addition, by receiving a load of about 3 to 15 kg acting on the opening / closing operation over the entire length of the two braking sleeves, it is possible to withstand an opening / closing test of several tens of thousands of times. The general-purpose hinge according to the present invention has an increase in the number of braking sleeves as a component compared to a conventional metal hinge, and the manufacturing cost is very low.

  The hinge according to the present invention may be attached to a connecting portion between the rotating body and the base material with a wood screw or a nail for furniture, joinery, containers, keyboard instruments, and the like having a rotating body such as a lid and an opening / closing door. With the hinge of the present invention, a lid such as furniture or joinery can be opened and closed, and can be stopped at an arbitrary opening angle. Therefore, with the hinge of the present invention, even if the load of the rotating body is applied to the leaf, the opening and closing operation is not performed shockingly, and it is possible to avoid the user from stuffing the rotating body with fingers or damaging the main body.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. The general-purpose hinge 1 according to the present invention is mainly made of metal, and is composed of two rectangular leaves 3 and 5 each provided with a countersink that is three mounting holes 2 as illustrated in FIGS. 1 and 2. .

  The first leaf 3 has an intermediate barrel portion 7 on its right side as shown in FIG. 3, while the second leaf 5 has its left side (right side in FIG. 4) as shown in FIG. Two barrel portions 8 and 10 at both ends are provided at predetermined intervals, and each barrel portion 7, 8 and 10 is formed by bending a rectangular metal piece into a circular shape. The intermediate barrel portion 7 has substantially the same inner diameter as the barrel portions 8 and 10. The length of the intermediate barrel portion 7 is smaller than the gap 12 (FIG. 4) between the barrel portions 8 and 10, and the length of the barrel portions 8 and 10 is added up. A rectangular flat protrusion 14 is formed below both end faces of the intermediate barrel portion 7.

  Two plastic braking sleeves 16 are normally used in the hinge 1 as shown in FIG. 7 and have a cylindrical shape as illustrated in FIG. 5B. The upper flange portion 18 and a rear portion having a smaller diameter than the flange portion. Part 20. The flange part 18 should just be an outer diameter substantially the same as the outer diameter of the intermediate barrel part 7, and is located between the end side barrel part 8 or 10 and the intermediate barrel part 7 at the time of an assembly. As shown in FIG. 5 (1), a notch 22 is provided on the peripheral wall of the flange portion 18, and the notch is fitted to the protrusion 14 of the intermediate barrel portion 7 during assembly. The rear portion 20 has an outer diameter that is substantially the same as the inner diameter of the intermediate barrel portion 7, and is fitted from the end surface of the intermediate barrel portion 7 during assembly (see FIG. 7). The brake sleeve 16 is an injection-molded product of wear-resistant engineering plastic (for example, polyacetal resin), and is colored black in this embodiment.

  On the other hand, two metal pivots 24 are normally used in the hinge 1 as shown in FIG. 7 and have an elongated cylindrical shape as illustrated in FIG. 6 (2). It has an intermediate portion 28 and a rear portion 30 having a smaller diameter than the head portion and the intermediate portion 28. For example, as shown in FIG. 6 (1), the grooved head portion 26 has twelve ridges in the circumferential direction by serration, and the ridge diameter is the outer diameter of the intermediate portion 28 and the first leaf 3. It is slightly larger than the inner diameter of the end barrel portion 8 or 10. The rear portion 30 has a diameter slightly larger than the inner diameter of the brake sleeve 16 and is press-fitted into the brake sleeve 16 located in the intermediate barrel portion 7 when assembled. The length of the rear portion 30 is determined such that the value obtained by subtracting the thickness of the two sleeve flange portions 18 from the two portions is slightly smaller than the length of the intermediate barrel portion 7.

  When assembling the hinge 1, as shown in FIG. 7, the two braking sleeves 16 are respectively fitted from the end surfaces of the intermediate barrel portion 7, and the notches 22 of the flange portions 18 are fitted to the protrusions 14 of the intermediate barrel portion 7.

Next, after aligning the axial centers of the intermediate barrel portion 7 of the first leaf 3 and the end side barrel portions 8 and 10 of the second leaf 5, the pivot 24 is pushed in from the end surface of the one end side barrel portion 8, When it is driven until the top surface of the head matches the barrel end surface, the grooved head 26 bites into the inner peripheral surface of the end barrel portion 8 and is integrated. Similarly, when another pivot 24 is pushed in from the end surface of the other end barrel portion 8 and is driven until the top surface of the head of the pivot matches the end surface of the barrel, the grooved head portion is inside the end barrel portion 10. It bites into and integrates into the peripheral surface, thereby completing the assembly.

  In the general-purpose hinge 1, the two pivots 24, 24 rotate and stop together with the second leaf 5 when the grooved head portion 26 bites into the inner peripheral surface of the barrel portion 8 or 10. On the other hand, the two brake sleeves 16 and 16 rotate and stand still together with the first leaf 3 when the notch 22 of the flange portion 18 is engaged with the protrusion 14 of the intermediate barrel portion 7. The rear portions 30 of the pivots 24 are respectively press-fitted into the brake sleeve 16 and are slidable on the inner peripheral surface of the brake sleeve. Therefore, the outer peripheral surface of both the pivot rear portions 30 and the inner peripheral surface of the brake sleeve 16 Becomes a friction surface, and both the leaves 3 and 5 can be stopped at an arbitrary opening angle.

  For example, when the general-purpose hinge 1 is used in place of the metal hinge 104 for the opening / closing lid 102 of the grand piano 100 in FIG. 9, the lid can be stopped at an arbitrary open position, and the same appearance as the metal hinge 104 can be obtained. Since it has, it is also aesthetically preferable. The general-purpose hinge 1 surrounds the outer peripheral surface of the two brake sleeves 16 with the intermediate barrel portion 7 of the first leaf 3 and can receive a load of about 5 to 15 kg depending on the size. The opening and closing operation is constant. The load acting during the opening / closing operation is received by the entire length of the two braking sleeves 16 so that the hinge 1 can withstand an opening / closing test of several tens of thousands of times.

  FIG. 8 shows a modification of the present invention, and the general-purpose hinge 40 is composed of two rectangular leaves 42 and 44. The first leaf 42 has an intermediate barrel portion 46 on the right side surface thereof. On the other hand, the second leaf 44 has two end barrel portions 48 and 50 at a predetermined interval. The barrel portion 48 is the same as the barrel portion 8 described above, and the barrel portion 50 is more than the barrel portion 48. It has a small diameter and a cross section of about 3/4 circle. The intermediate barrel portion 46 has substantially the same inner diameter as the barrel portion 48 and forms a rectangular flat protrusion (not shown) below the end surface on the barrel portion 48 side.

  The cylindrical plastic braking sleeve 52 has an upper flange portion 54 and a rear portion 56 having a smaller diameter than the flange portion. The flange portion 54 is located between the end side barrel portion 48 and the intermediate barrel portion 46 at the time of assembly. A notch (not shown) is provided in the peripheral wall of the flange portion 54, and the notch is fitted to the protrusion of the intermediate barrel portion 46 during assembly.

  On the other hand, an elongated cylindrical metal pivot 58 includes a grooved head portion 60, an intermediate portion 62 below the head portion, a rear portion 64 having a smaller diameter than the head portion and the intermediate portion 62, and a rear portion. Furthermore, it has the rear-end part 66 of a small diameter. The grooved head 60 has a crest having a diameter slightly larger than the outer diameter of the intermediate portion 62 and the inner diameter of the end barrel portion 48. The rear portion 64 has a diameter slightly larger than the inner diameter of the brake sleeve 52 and is press-fitted into the brake sleeve 52 located in the intermediate barrel portion 46 when assembled. The rear end portion 66 has substantially the same length as the end-side barrel portion 50, and the cross section thereof is 3/4 circle similar to the cross section of the barrel portion 50.

  When the hinge 40 is assembled, the braking sleeve 52 is fitted from the upper end surface of the intermediate barrel portion 46 of the first leaf 42, and the notch of the flange portion 54 of the sleeve is fitted to the protrusion of the intermediate barrel portion 46. Next, after aligning the axial centers of the barrel portions 48, 50 of the second leaf 44 and the intermediate barrel portion 46 of the first leaf 42, the pivot 58 is pushed in from the end surface of the end side barrel portion 48, and When the surface is driven until it coincides with the barrel end surface, the grooved head portion 60 bites into the inner peripheral surface of the end side barrel portion 48 and is integrated. At this time, the rear end portion 66 of the pivot 58 enters the other barrel portion 50, and both of them have the same deformed cross section, so that they can be rotated and stopped integrally.
