Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bracket for incorporating a damper mechanism, such as a piano keyboard cover and a toilet seat, in a hinge so as not to close with force due to its own weight when the hand is released.
[0002]
[Prior art]
As a part constituting the hinge provided with the damper mechanism, there is a damper member 1 shown in FIG. The damper member 1 includes a cylindrical main body 2 incorporating a damper mechanism and a shaft portion 3.
The damper member 1 exhibits a damping force when the shaft portion 3 is rotated in one direction with respect to the main body 2. The damper member 1 rotates clockwise depending on the damping force, that is, the rotation direction of the shaft portion 3 that exhibits a damper function. There is a damper (R) for left rotation and a damper (L) for left rotation.
Further, as shown in FIG. 5, the damper member 1 has a rotation stop protrusion 2 a at the rear end of the main body 2 and a stop surface 3 a in which both surfaces of the shaft portion 3 are flat.
When such a damper member 1 is attached, brackets 4 and 5 as shown in FIG. 6 may be used.
[0003]
The bracket 4 is a cylindrical bracket into which the main body 2 of the damper member 1 is inserted. Although not shown in detail, the bracket 4 has a stopper 4 that fits the rotation-stop protrusion 2a so that the main body 2 does not rotate. The part is formed.
On the other hand, the bracket 5 has the same outer shape as the bracket 4 but is a bracket into which the shaft portion 3 side of the damper member 1 is inserted. And in the bracket 5 , in order to control rotation of the said shaft part 3, the stop hole which corresponds to the outer periphery of the shaft part 3 which formed the stop surface 3a and was flattened is formed.
[0004]
That is, by fitting the bracket 4 and the bracket 5 from both sides of one damper member 1 and fixing them to, for example, a piano body and a keyboard lid, it can function as a set of hinges provided with a damper mechanism. it can.
In this case, one bracket 4 is integrated with the main body 2 of the damper member 1, and the other bracket 5 is integrated with the shaft portion 3 and rotates relative to each other.
[0005]
[Problems to be solved by the invention]
As described above, a set of hinges is composed of two brackets 4 and 5 and one damper member 1.
In order to support the torque determined by the weight and size of a rotating member such as a lid with such brackets 4 and 5, a damper member having a size corresponding to the torque must be used. For example, in order to cope with a large torque, a large damper member must be used, and in order to cope with a small torque, a suitable small damper member must be used.
[0006]
If it is too small, a sufficient damper function cannot be obtained, and if it is too large, the lid cannot be easily closed.
Thus, it is conceivable to use a plurality of hinges incorporating a damper member corresponding to a certain amount of torque to cope with a large torque. For example, if a pair of hinges as shown in FIG. 6 can cope with the torque of W, if N pairs of hinges are attached, a torque N times W can be accommodated.
[0007]
However, a pair of hinges requires two brackets. In other words, twice as many brackets must be attached to the damper member, and the larger the number of hinges, the larger the space for attaching them. Therefore, in order to cope with a large torque, the installation location is limited.
In addition, when a plurality of sets of hinges are individually arranged and attached, there is a problem that it is very difficult to align the axes of all the hinges.
SUMMARY OF THE INVENTION An object of the present invention is to provide a damper bracket that can be easily aligned with a shaft and can handle various torques.
[0008]
[Means for Solving the Problems]
The present invention is premised on a damper bracket that supports a damper member having a circular cross-section damper body and a shaft protruding from the damper body with a support cylinder.
According to a first aspect of the present invention, the support cylinder includes a pair of cylinder portions having openings at both ends thereof and having an inner diameter slightly larger than the outer diameter of the damper main body. each, to form a stop portion of both for damper body and the shaft portion, to insert the damper member to the support cylinder, by the stopper portion, the relative rotation between the damper body or shaft portion and the support cylinder It is characterized in that it is regulated .
[0009]
The second invention is based on the first invention, and the support cylinder holds an inner diameter for rotatably supporting the damper main body, and the support cylinder and the damper are arranged in a state where the shaft portion is fixed to the stop portion. It is characterized in that the dimensional relationship is maintained so that the main body is inserted into the support tube.
The third invention is premised on the first and second inventions, and is characterized in that the pair of cylindrical portions and the stopper formed on the bottom surface have the same shape .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of the present invention.
The damper supported by using the bracket of the present invention is the same as that of FIG. 5 described in the conventional example, and will be described using the reference numerals of FIG.
The external appearance of the bracket 6 of the present invention is the same as the conventional one, and the support cylinder 7 is provided with a fixing portion 8. Then, a screw or the like is inserted into the fixing hole 8a formed in the fixing portion 8, and is fixed to a necessary portion.
FIG. 1 shows a view of the bracket 6 as viewed from one end side, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG.
[0011]
As shown in FIGS. 1 and 2, in the support cylinder 7, cylinder parts 9 and 9 having dimensions capable of rotatably supporting the damper main body 2 are formed on both opening sides. That is, the inner diameters of the cylindrical portions 9 and 9 are slightly larger than the outer diameter of the damper main body 2.
A stop hole 10, 10 in which the rotation stop protrusion 2 a of the damper member 1 of FIG. 5 coincides is formed from the bottom surface of the tube part 9, toward the center of the support cylinder 7, and the shaft part 3 is formed at the center thereof. A stop hole 11 is formed that coincides with the outer periphery. That is, the stop hole 10 is a stop portion for the damper main body 2, and the stop hole 11 is a stop portion for the shaft portion 3. In this embodiment, the retaining holes 10 and 11 are both long holes and are formed so that their major axis directions are orthogonal to each other.
[0012]
The usage pattern of the damper bracket 6 is shown in FIG. As shown in FIG. 3, the damper for left rotation 1 </ b> L and the damper for right rotation 1 </ b> R can be connected and used by the damper bracket 6.
The left rotation damper 1L and the right rotation damper 1R are the same as the damper member 1 of the conventional example shown in FIG. The reference numerals of the respective parts of the left rotation damper 1L are indicated by L, and the reference numerals of the respective parts of the right rotation damper 1R are indicated by R. The left and right rotation dampers 1L and 1R have the same outer shape, but the rotation directions of the shafts 3L and 3R that exhibit the damper function with respect to the damper main bodies 2L and 2R are different.
[0013]
The damper bracket 6 configured as described above is bilaterally symmetric with respect to the plane including the axial center thereof, so that it is common even when attached to the fixed side and the rotating side, such as the main body and the lid. Can be used.
In FIG. 3, among the three brackets 6, separate damper members 1 </ b> L and 1 </ b> R are inserted into the cylindrical portions 9 and 9 on both sides of the central bracket 6, respectively, so that the rotation stop protrusions 2 a </ i> R and 2 a </ i> L Is fitted in the stop holes 10 and 10. Further, the shaft portions 3L, 3R of the damper members 1L, 1R are inserted into the retaining holes 11 of another bracket 6.
[0014]
As shown in FIG. 3, the two damper members 1 </ b> L and 1 </ b> R can be connected by the three brackets 6. For example, the brackets 6 and 6 at both ends are fixed to the lid, and the central bracket 6 is fixed to the main body, so that the lid can be used as a damper hinge. However, in the case of being connected and used as shown in FIG. 3, one must be the right-turn damper member 1 </ b> R and the other must be the left-turn damper 1 </ b> L.
[0015]
In this case, the two damper members 1L and 1R can cope with a torque twice as large as the corresponding torque provided in the conventional pair of hinges shown in FIG.
When two sets of conventional hinges are used, four brackets have to be attached. However, in the case of the bracket 6 of this embodiment, in order to cope with the same torque, the three brackets and the left and right rotations are used. One damper member is sufficient for each.
Further, in this embodiment, as shown in FIG. 3, the bracket 6 and the damper members 1L and 1R can be handled in an integrated manner. Therefore, it does not take time to align the axes as in the case where each hinge is attached individually.
[0016]
Note that the axial lengths L1 and L1 of the cylindrical portions 9 and 9 of the bracket 6 are slightly smaller than ½ of the axial length L2 of the damper main bodies 2L and 2R. For this reason, as shown in FIG. 3, when they are joined, there is no gap between the brackets 6 and they are not rubbed against each other during rotation.
Further, in FIG. 3, the damper main bodies 2L and 2R are also inserted partway into the brackets 6 on both sides to which the shaft portion 3 is fixed. A radial load such as a lid is not received by the shaft portions 3L and 3R, but can be supported by the main bodies 2L and 2R having higher load resistance. Accordingly, the shaft portions 3L and 3R can be prevented from being damaged due to the radial load applied to the shaft portions 3L and 3R.
As in the prior art, when only the shaft portion 3 is inserted and fixed to one bracket, the weight of the lid or the like must be supported by the shaft portion 3, so that the shaft portion 3 is easily damaged. It was.
[0017]
FIG. 4 shows a case where the bracket 6 is used and the plurality of damper members 1L and 1R are aligned in series and connected in series.
In FIG. 4, the shaft portions 3L, 2R and the main body are mounted on the bracket 6 alternately arranged for the fixed side and the rotating side with the shaft portions 3L, R of the damper members 1L, 1R on the left side and the main bodies 2L, 2R on the right side. 2L and 2R are inserted.
First, the shaft portion 3L of the damper main body 1L is inserted from one opening of the left end bracket 6 so that the main body 2L is supported by the cylindrical portion 9 and the shaft portion 3L is fixed in the retaining hole 11. The damper body 2L is inserted into the next bracket 6 on the side of the rotation stop protrusion 2aL, and the body 2L is supported by the cylindrical portion 9, and the rotation stop protrusion 2aL is fitted into the stop hole 10 and fixed. On the opposite side of the bracket 6, the shaft 3R side of another damper member 1R is inserted.
[0018]
FIG. 4 shows a state in which the three damper members 1L, 1R, and 1L are connected by the four brackets 6 as described above. In this case, it is possible to cope with a torque three times as large as when one damper member 1 is used. If the conventional hinge shown in FIG. 6 is used to cope with the same torque, three sets of hinges must be used. That is, six brackets must be attached, but if the bracket 6 of this embodiment is used, four brackets 6 are sufficient. In addition, there is no need to align the shaft center.
In this embodiment, the stop hole 11 as a stop for the shaft portion 3 passes through the support tube, but the central portion of the support tube 7 is the boundary wall of the present invention. In short, in this embodiment, the stop hole 11 penetrates the boundary wall. And the cylinder part 9 which supports damper main body 2L, 2R and the stop hole 10 which controls rotation of main body 2L, 2R are formed in both sides via this boundary wall.
[0019]
Furthermore, in the said Example, since the bracket 6 is right-and-left symmetrical, even if it arranges with the direction of damper member 1L, 1R reversed as shown in FIG. 3, it can connect. If the shape is not symmetrical, the side on which the damper main body 2 is inserted and the side on which the shaft portion 3 is inserted are determined, so two types of bracket shapes need to be prepared. Even in such a case, it is possible to cope with a smaller number of brackets than in the conventional example, and it is possible to obtain an effect that the labor for aligning the shaft center is not required.
Moreover, in the said Example, since the flat surface of the rotation stop protrusion 2a and the stop surface 3a of the axial part 3 are orthogonal, the major axis of the stop holes 10 and 11 is orthogonally crossed. However, the positional relationship between the retaining holes 10 and 11 must be changed depending on the positional relationship between the rotation-preventing protrusion 2 a of the main body 2 and the shaft portion 3.
[0020]
【The invention's effect】
According to the first invention , a plurality of damper members can be connected and used as a set of hinge units. As in the conventional example, the number of brackets to be attached can be reduced even when dealing with a large torque, compared to a pair of brackets forming a pair of hinges. Therefore, the degree of freedom of the installation location increases.
In addition, since a plurality of damper members and brackets can be integrated, the labor of alignment is saved.
In addition, since the pair of bottom surfaces are provided with both a stopper for the damper body and a stopper for the shaft, the shaft is inserted from either side of the bracket. Also, their rotation can be regulated and supported. Therefore, any type of connection of the damper member can be handled with one type of bracket.
Furthermore, since the corresponding torque can be adjusted by the number of damper members, there is no need to separately prepare a damper member according to the required torque, which is economical.
[0021]
According to the second invention, since the damper main body is inserted into the bracket for fixing the shaft portion of the damper member, the weight of the rotating member is supported not only by the shaft portion but also by the damper main body. There is no direct impact on the department. Therefore, the durability of the shaft portion is improved.
According to the third invention, it is possible to also Dochi et bracket coupling is attached takes a damper member of the same shape.
