Description

  The present invention relates to a hinge used for a door in a house or the like, for example.

  As shown in FIG. 7, the hinge as in the above example is inserted into two blade members 101, 101 having bearing portions 101 a that mesh with each other, and the bearing portion 101 a of the blade member 101, and the blade member 101. It has a structure having shaft members 102 and 103 that are coupled to each other so as to be rotatable relative to each other, and is configured such that the opposing surfaces of the bearing portion 101a come into sliding contact with the rotation.

  The blade member 101 having the bearing portion 101a is manufactured by winding a stainless steel plate. Since it is made of stainless steel, it does not easily wear even if it slides on each other during rotation.

  However, the door is fixed like a hinge on the side of the door frame. For example, when the door knob is used to apply force from above, or when a roll occurs due to an earthquake, the hinge is Takes a tilting force.

  When such a force is applied, a load is easily applied to a portion where the bearing portions 101a of the blade member 101 are in contact with each other, and there is a problem that deformation occurs depending on circumstances.

  In particular, in the case of a house door, considering the door attachment and detachment, as shown in FIG. 7, each blade 101, 101 has a structure in which one bearing portion 101a is formed. Force is easy to act.

  Until now, a stainless steel ring (not shown) has been interposed between the bearing portions 101a. However, the ring is independent of the bearing portion 101a and does not eliminate the above-mentioned drawbacks. There is nothing that tried to eliminate. In addition, when a ring is used, only the portion that comes into sliding contact is increased, and care such as lubrication is indispensable.

  In addition, although it is a hinge used for a clean room, as disclosed in Patent Document 1 below, a flanged resin bush and a resin washer are provided between the bearing portions of the blade member, and a metal shaft and metal Proposals have been made in which metal blade members and metal blade members are not directly rubbed to generate metal powder. According to this hinge, the resin bush and the resin washer are formed of an oil-containing resin, and generation of dust can be suppressed.

  However, since there is no contact between the metals, the portion between the shaft member and the bearing portion is largely open at portions other than the resin bush, and therefore a large load is applied only to the resin bush portion. Further, since the load is supported by sliding contact with the resin bush portion, a resin bush and a resin washer must be provided between all the bearing portions. For this reason, the number of necessary members is large and the necessary cost is increased.

JP 2000-204832 A

  The main object of the present invention is to increase the strength against a load and to enable a stable rotation operation. It is also an object to enable manufacturing at low cost.

  Means for this is a hinge having a blade member having a bearing portion that meshes with each other and a shaft member that is inserted into the bearing portion of the blade member and is coupled to the blade member so as to be capable of relative rotation. A bearing portion interposed between the bearing portions at a thickness corresponding to the size of a gap provided between the bearing portions of the blade member to be coupled to the inner peripheral surface of one of the two bearing portions arranged in the direction. It is a hinge which has a hook part which makes the non-contact each other, and has a hooked bush having an insertion hole through which the shaft member passes, and is configured such that the blade members are not in contact with each other.

  The bush with a hook is a cylindrical member fitted into the bearing portion and is held by press-fitting or the like. One of the two bearing portions arranged in the length direction of the shaft member is provided with a flanged bush, and the flange portion of the flanged bush has a thickness corresponding to the thickness of the gap provided between the bearing portions. Since there are, only bushed bushes will be interposed. The hooked bush is formed with an insertion hole through which the shaft member is passed, and a rotatable coupling is performed in a state where at least the hooked bush portion in the bearing portion is in sliding contact with the shaft member.

  Thus, since the collar part of a bush with a collar is located between bearing parts, contact between blade members can be avoided and especially wear of a bearing part can be eliminated.

  Further, when a tilting force is applied to the hinge, the hooked bush held by the bearing portion receives a load integrally with one of the bearing portions, and reduces the load on the bearing portion and the shaft member. When the material of the bush with a hook is softer than the blade member or the shaft member, the deformation of the bearing or the shaft member is prevented by the deformation of the bush with a hook. As a result, the strength against the load is high, and a stable rotation operation can be realized over a long period of time.

  Further, since the strength against the load is high as described above, the blade member can be made of, for example, an aluminum alloy instead of the stainless steel that has been used so far. When the blade member is formed of an aluminum alloy, it can be manufactured by extrusion molding as well as winding from a plate material. Moreover, it can be manufactured at a lower cost in terms of material costs and manufacturing costs than using stainless steel.

  Here, each of the above-described components can be configured in the following manner.

In one of the modes, an annular stepped portion is formed on the inner peripheral surface of one of the two bearing portions arranged in the length direction of the shaft member, and opens to the end surface on the other bearing portion side. At the same time, the bush with the hook is held on the annular stepped portion.
That is, since the flanged bush is held in the annular step portion by press fitting or the like, the load applied to the flanged bush can be supported on many surfaces, and durability against a large load can be enhanced. In addition, if the blade member is made of an aluminum alloy, the annular step portion can be easily and inexpensively formed unlike the case of stainless steel.

In this case, the inner diameter of the insertion hole of the bushed bush and the inner diameter of the bearing portion may be set to be the same.
In other words, the shaft member is in sliding contact with the inner peripheral surface of the insertion hole of the flanged bush, and is also in sliding contact with the inner peripheral surface of the bearing portion. And can realize a stable rotation.

In another aspect, one bearing portion is formed on one blade member, and one bearing portion is formed on the other blade member.
That is, even in a door that can be easily attached and detached, the strength against a load can be increased to enable a stable turning operation.

Another aspect is that each of the blade members is formed with two or more bearing portions, and any one of the two bearing portions positioned on both end sides in the length direction of the shaft member in each blade member. On the other hand, the hooked bush is held, and a portion between the bearing portions interposing the hooked bush is configured to be non-contact without having the hooked bush.
That is, even a heavy hinge can increase the strength against a load and enable a stable turning operation. And since the site | part between the bearing parts which interpose a bush with a hook is comprised in non-contact, and it does not have a bush with a hook, the increase in a number of parts can be suppressed and it can manufacture more cheaply.

In another aspect, the blade member is formed of an aluminum alloy.
That is, as described above, it can be manufactured at a lower cost than stainless steel in terms of material cost, and the manufacturing can also employ extrusion in addition to the winding process, and the cost can be suppressed as a whole.

In another aspect, the bushed bush is formed of an oil-containing material.
That is, the bush with a hook is composed of a synthetic resin molded product or a powder molded product, and has a lubricity, so that a favorable rotation operation can be expected. In particular, when formed of a synthetic resin, the hardness can be made lower than that of a metal, so that the buffering action is enhanced.

  As described above, according to the present invention, it is possible to increase the strength against a load and enable a stable rotation operation. Further, even if the blade member is formed of, for example, an aluminum alloy instead of the stainless steel that has been used so far, high strength and a stable rotation operation can be realized, so that a good product can be obtained at a low cost.

An embodiment for carrying out the invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a hinge 11 suitable for use in a door, and FIG. 2 is an exploded perspective view thereof.

  As shown in these drawings, the hinge 11 is configured such that two blade members 21 and 22 meshing with each other, a bushing 31 held by one blade member 21, and the blade members 21 and 22 are rotatably coupled to each other. It consists of two long and short fixing pins 41 and 42. The blade members 21 and 22 are made of an aluminum alloy, and the bushed bush 31 is made of an oil-containing synthetic resin molded product or a powder molded product. The two fixing pins 41 and 42 are made of stainless steel.

  The blade members 21 and 22 have a cylindrical bearing portion 24 that is slightly shorter than half the length of the plate-like portion 23 on one side of the plate-like portion 23 having a rectangular plate shape. The bearing portion 24 is formed close to the end in the length direction. The internal insertion hole 25 is set to a thickness that allows the fixing pins 41 and 42 to be inserted. The blade members 21 and 22 can be manufactured by bending a plate material, or by punching the extruded product 51 as shown in FIG. In the example of illustration, the example manufactured by extrusion is shown. In the figure, 23a is a screw hole.

  An annular step 26 is formed on one of the two blade members 21 and 22 (the blade member 21 having the bearing portion 24 positioned below when coupled). The annular step portion 26 is a portion that holds the above-described flanged bush 31 and extends from the end surface 24a to an appropriate depth so as to open to the end surface 24a on the other bearing portion 24 side on the inner peripheral surface of the bearing portion 24 facing each other. It is formed. The lower end surface 26a of the annular step portion 26 is formed flat.

  The hooked bush 31 has a substantially cylindrical shape, and the inner diameter of the inner insertion hole 32 is the same as the inner diameter of the insertion hole 25 of the bearing portion 24. A flange 33 having a thickness corresponding to the size of a gap provided between the bearing 24 of the blade member 22 to be coupled is formed at one end in the length direction.

  The fixing pins 41, 42 are inserted into the bearing portion 24 and the insertion holes 25, 32 of the bushed bush 31 held by the bearing portion 24. As shown in FIG. 41 is inserted from the side of the bearing portion 24 of the blade member 22 that does not hold the bushed bush 31. The length is a length exceeding the hooked bush 31 portion when the insertion is completed. The shorter fixing pin 42 is inserted into the bearing portion 24 of the blade member 21 that holds the bushed bush 31.

  The hinge 11 made up of such members is first inserted into the blade member 21 having the annular step portion 26 by press-fitting the bushing 31 with the hooks and held together, and then the blade 11 using the fixing pins 41 and 42. The members 21 and 22 are joined together.

  FIG. 5 shows an example of a usage state of the hinge 11, in which the blade member 21 holding the bushed bush 31 is fixed to the door frame 61 and the other blade member 22 is fixed to the door 62. In such a use state, the bushed bush 31 is integrated with one blade member 21, and the flange portion 33 is interposed between the other blade member 22. Since the flanged bush 31 and the insertion hole 25 of the bearing portion 24 have the same diameter, a wide contact surface can be obtained, a stable turning operation can be expected, and the load can be supported in a well-balanced manner. Further, since the bushed bush 31 is oil-impregnated, the coefficient of friction is small, smooth rotation is possible, and maintenance can be simplified.

  And since the collar part 33 of the bushing 31 with a hook cuts off contact between the blade members 21 and 22, there is no fear that the blade members 21 and 22 and especially the bearing parts 24 will rub and wear each other over a long period of time. A good use state is obtained.

  In addition, when a tilting force is applied to the hinge 11 through the door 62 or the like, the load is supported by the wide contact surface as described above, and the hooked bush positioned between the two blade members 21 and 22 is provided. 31 acts as a buffer to prevent deformation of each part. As a result, the load applied to the bearing portion 24 can be reduced and high strength can be obtained. Moreover, since the hooked bush 31 is integrally held by one of the blade members 21, it is possible to reduce the portion that is in sliding contact with each other as much as possible. Suppresses and acts as a buffer. Further, since the number of parts when disassembled can be reduced, there is an advantage that operations such as assembly are easy.

  Further, since the strength is high and stable rotation is possible as described above, a sufficient function as a hinge can be obtained without increasing the strength of the blade members 21 and 22 themselves. For this reason, the blade members 21 and 22 can be formed of an aluminum alloy as described above. Aluminum alloys have advantages such as better processability and lower material costs than stainless steel, so that these advantages can be enjoyed. As a result, a cheap and good quality hinge 11 can be obtained.

  FIG. 6 shows a hinge 11 for a heavy article according to another example. That is, two or more bearing portions 24 are formed on the two blade members 21 and 22, respectively. Specifically, two bearing portions 24 and 24 are provided on one blade member 21, and three bearing portions 24... That mesh with the other blade member 22 are provided. And the said bush 31 with a hook is hold | maintained at either one of the two bearing parts 24 located in the both ends side of the length direction of the fixing pins 41 and 42 in each blade | wing member 21 and 22. The part between the bearing parts 24 that interposes is configured in a non-contact manner without a hooked bush. In other words, a gap is provided around the intermediate bearing portion 24 in the other blade member 22.

  Since the flanged bush 31 is preferably held by the bearing portion 24 positioned below at the time of coupling, the upper bearing portion 24 of the one blade member 21 and the lowermost bearing portion 24 of the other blade member 22 are used. In addition, an annular step portion 26 is formed.

  Other configurations are the same as those described above, and thus detailed description thereof is omitted.

  As described above, even the heavy hinge 11 having a large number of bearing portions 24 can increase the strength against the load and enable a stable rotation operation. And since the site | part between the bearing parts 24 which interpose the bush 31 with a hook is comprised in non-contact, and it does not have a bush with a hook, the increase in a number of parts can be suppressed and it can manufacture more cheaply.

In correspondence between the configuration of this device and the configuration of the above-described one form,
The shaft member of this device corresponds to the fixing pins 41 and 42 described above,
The present invention is not limited to the above-described configuration, and other forms can be used.
For example, the shaft member may be composed of a single member.
