Description

  The present invention relates to a vibration isolator for moving partitions.

  As a device that absorbs vibration generated when the moving partition moves on the hanger rail, a moving partition vibration isolator is known (for example, see Patent Document 1). As shown in FIG. 6, the vibration isolator for moving partition disclosed in Patent Document 1 also has a function of fixing the hanger rail 510 to a fixing member 520 fixed to a slab on an upper floor via a hanging bar 600. The spacer 540 is disposed between the mounting surface 511 that is the upper plate portion of the hanger rail 510 and the mounting surface 521 of the fixing member 520, and the soft rubber is provided on the opposite side of the mounting surface 521 of the fixing member 520. A flat plate 550 is disposed through a vibration isolating material 530 made of a bolt shaft 561 penetrating the mounting surface 511 of the hanger rail 510, the spacer 540, the mounted surface 521 of the fixing member 520, the vibration isolating material 530, and the flat plate 550. The nut member 570 is screwed and the bolt 560 and the nut member 570 are tightened.

  The moving partition vibration isolator configured as described above is assembled as follows. First, as shown in FIG. 6, a spacer 540 is disposed on the mounting surface 511 of the hanger rail 510, and a flat plate 550 is disposed on the opposite side of the mounting surface 521 of the fixing member 520 via a vibration isolator 530. Set up. The nut member 570 is screwed onto the bolt shaft 561 penetrating the mounting surface 511 of the hanger rail 510, the spacer 540, the mounted surface 521 of the fixing member 520, the vibration isolator 530, and the flat plate 550.

  Next, by tightening the bolt 560 and the nut member 570, as shown in FIG. 7, the hanger rail 510 is raised and the spacer 540 is brought into contact with the mounting surface 521 of the fixing member 520. Thereafter, the bolt 560 and the nut member 570 are further tightened to fix the hanger rail 510 to the fixing member 520. As a result, the flat plate 550 descends and comes into pressure contact with the vibration isolator 530. The anti-vibration material 530 is made of soft rubber, and is deformed by the press contact of the flat plate 550 to be thin. For this reason, according to the tightening of the bolt 560 and the nut member 570, the flat plate 550 is moved from the position shown by the alternate long and short dash line (position shown in FIG. 7) to the position shown by the solid line as shown in FIG. The vibration isolator 530 is lowered while being deformed. By adjusting the position of the flat plate 550 in this way, the hanger rail 510 is firmly fixed to the fixing member 520.

  As described above, by providing the vibration isolator 530 between the flat plate 550 and the fixing member 520, the fixing strength of the hanger rail 510 with respect to the fixing member 520 is changed by changing the degree of pressure contact of the vibration isolating material 530 by the flat plate 550. can do. Further, vibration generated by the movement partition moving on the hanger rail 510 is absorbed by the vibration isolator 530 when transmitted from the hanger rail 510 to the flat plate 550 via the bolt 560 or from the hanger rail 510 via the spacer 540. Or absorbed by the vibration isolator 530. Therefore, vibration transmitted from the hanger rail 510 to the fixing member 520 is blocked by the vibration isolator 530.

Japanese Patent No. 3660847

  However, in the vibration isolator for moving partition shown in Patent Document 1, the vibration isolator 530 disposed between the flat plate 550 and the fixing member 520 is made of soft rubber. Regardless of how the degree is set, the following problems occur depending on the degree of pressure contact.

  That is, if the degree of pressure contact of the vibration isolator 530 by the flat plate 550 is reduced at the time of construction so that the vibration isolator 530 can sufficiently exhibit the anti-vibration function, the weight of the moving partition is always applied to the flat plate 550. Therefore, the vibration isolator 530 is elastically deformed by the pressure contact from the flat plate 550. When the moving partition is suspended over a long period of time, the elastic deformation of the vibration isolator 530 proceeds and the flat plate 550 falls, so that a gap is generated between the fixing member 520 and the spacer 540 and the mounting height of the hanger rail 510 is lowered. Therefore, there is a possibility that the movement of the moving partition may be hindered if the height position is not aligned at the joint of the hanger rail 510 or if the hanger rail 510 rattles when the moving partition moves.

  On the other hand, such a change in the height position of the hanger rail 510 due to long-term use can be prevented to some extent by adjusting the tightening amount of the bolt 560 in accordance with the weight of the moving partition during construction. That is, when the vibration isolator 530 is pressed as much as possible by the flat plate 550 at the time of construction, the vibration isolator 530 is not further elastically deformed by the press contact from the flat plate 550 after the construction. Therefore, the change in the height position of the hanger rail 510 due to long-term use is eliminated. However, since the vibration isolator 530 is pressed as much as possible, there is a problem that the vibration isolating function of the vibration isolator 530 is lowered.

  Therefore, the present invention has been made in view of such problems, and the object of the present invention is to keep the hanger rail mounting height constant even in long-term use without deteriorating the vibration isolating function of the vibration isolating material. An object of the present invention is to provide a vibration isolator for a moving partition that can be kept at a low level.

  In order to solve the above-described problems, according to the present invention, a vibration isolating material provided between an attachment surface that is an upper plate portion of a hanger rail for moving partition and an attachment surface of a fixing member, and the fixing member The mounting surface of the hanger rail includes a flat plate provided via a spacer on the opposite side of the mounting surface to the vibration isolator, so that the bolt does not contact the mounting surface of the fixing member. The bolt shaft of the bolt is passed through the vibration isolator, the mounting surface of the fixing member, the spacer, and the flat plate, and the nut member is screwed to the bolt shaft, thereby tightening the bolt and the nut member. By pressing the mounting surface of the hanger rail against the vibration isolator, the distance between the flat plate and the fixing member is kept constant by the spacer, and the fixing of the hanger rail is performed. And adjusting the mounting height for the timber, for moving partition vibration damping device is provided.

  In the present invention, the vibration isolator can be composed of, for example, soft rubber having a Shore hardness of 60 or less, the spacer can be composed of, for example, hard rubber having a Shore hardness of 60 or more, and the Shore hardness of the spacer Is 20 or more harder than the anti-vibration material.

  According to the present invention, by providing the spacer that can keep the distance between the flat plate and the fixing member constant, the flat plate does not descend even when the weight of the moving partition is applied. Thereby, the attachment height of a hanger rail can be made constant. Further, since the height of the hanger rail can be kept constant by the spacer, there is no step in the rail joint, and the mounting state can be stabilized even for long-term use.

  Further, since the spacer is arranged between the flat plate and the fixing member, the pressure contact by the flat plate due to the bolt tightening is received by the spacer, so that the distance between the flat plate and the fixing member can be kept constant. Thereby, it is not necessary to adjust the tightening amount of the bolt in accordance with the weight of the moving partition on the flat plate, and can be made constant.

  In addition, since the vibration isolator is provided between the hanger rail and the fixed member, the flat plate that is heavy on the moving partition does not press the vibration isolator. For this reason, in order to eliminate the change of the height position of a hanger rail by long-term use, it is not necessary to press-contact a vibration isolator as much as possible. Therefore, the vibration isolating function of the vibration isolating material is not impaired.

  Furthermore, according to the present invention, vibration and noise in the hanger rail during traveling of the moving partition are provided by arranging a vibration isolator between the hanger rail and the fixed member and a spacer between the fixed member and the flat plate. Is absorbed by the anti-vibration material and hardly transmitted to the fixing member. For this reason, the vibration and noise at the time of travel of a movement partition can be eased. Further, since there is no direct contact between the flat plate and the fixing member due to the spacer, vibration and noise transmitted from the bolt shaft to the flat plate can be mitigated with respect to the fixing member.

  According to the present invention, it is possible to keep the mounting height of the hanger rail constant even in long-term use without deteriorating the vibration isolating function of the vibration isolating material. The other effects of the present invention will be clarified from the entire specification and drawings.

First, the whole structure of the vibration isolator 100 for moving partitions of this embodiment is demonstrated, referring FIG. The moving partition vibration isolator 100 is provided with a vibration isolator 130 between the mounting surface 111 that is the upper plate portion of the moving partition hanger rail 110 and the mounted surface 121 of the fixing member 120. The mounting surface 111 of the hanger rail 110 is provided on the opposite side of the mounting surface 121 of the mounting surface 121 to the vibration isolating material 130 via the spacer 140 so as not to contact the mounting surface 121 of the fixing member 120. The bolt shaft 161 of the bolt 160 is passed through the vibration member 130, the mounting surface 121 of the fixing member 120, the spacer 140, and the flat plate 150, and the nut member 170 is screwed into the penetrated bolt shaft 161. By tightening, the mounting surface 111 of the hanger rail 110 is brought into pressure contact with the vibration isolator 130 so that the distance between the flat plate 150 and the fixing member 120 is increased. While keeping constant by p o 140, configured to adjust the height position relative to the fixed member 120 of the hanger rail 110.

  Hereinafter, each component of the vibration isolator 100 for moving partitions of this embodiment is demonstrated.

(Hanger rail 110)
As shown in FIG. 2, the hanger rail 110 includes a rail portion 112 that accommodates the runner 220 so that the runner 220 can travel, and the upper end of the rail portion 112 is a mounting surface 111 that is a horizontal upper plate portion. A through hole 113 through which the bolt shaft 161 of the bolt 160 passes is formed in the mounting surface 111. As shown in FIG. 1, the end portion of the ceiling 20 is locked to the lower end portion 114 of the hanger rail 110.

(Fixing member 120)
As shown in FIG. 2, the fixing member 120 has a substantially U-shaped cross section with the upper side open, and is fixed to the above-described suspension bar 400 by welding. The lower plate portion of the fixing member 120 forms a horizontal attached surface 121. A through-hole 122 through which the bolt shaft 161 of the bolt 160 passes is formed in the attached surface 121 of the fixing member 120.

(Anti-vibration material 130)
The vibration isolator 130 absorbs vibration generated by the movement partition 200 moving the hanger rail 110 and has a function for adjusting the mounting height of the hanger rail 110. In order to achieve these functions, the vibration isolator 130 is made of a highly elastic member, and in this embodiment can be made of soft rubber. According to the inventor's knowledge, in the situation of use as in the present embodiment, the anti-vibration material 130 can use a soft rubber having a Shore hardness of about 60 or less, and according to the weight of the moving partition 200, It is preferable to use one having a Shore hardness of about 40-60.

  As shown in FIG. 2, the vibration isolator 130 has a thin cubic shape, and a plurality of irregularities are formed on the upper and lower surfaces. Each convex portion is configured so that the height thereof is appropriately different, and the vibration isolator 130 is easily elastically deformed by the convex portions having different heights. The vibration isolator 130 is formed with a through hole 131 through which a bush 142 of a spacer 140 described later passes.

  The anti-vibration material 130 configured as described above is disposed between the hanger rail 110 and the fixing member 120, and thereby absorbs vibration generated by the movement partition 200 moving the hanger rail 110. Further, as will be described later, the vibration isolator 130 is elastically deformed by being pressed against the mounting surface 111 of the hanger rail 110 by tightening the bolt 160 and the nut member 170, thereby allowing the hanger rail 110 to rise. For this reason, the mounting height of the hanger rail 110 is adjusted according to the elastic deformation amount of the vibration isolator 130.

  In addition, the material and shape of the vibration isolator 130 of this embodiment are examples, and are not limited to this. If the vibration isolator 130 has the function of absorbing vibration and the function of adjusting the mounting height of the hanger rail 110 as described above, for example, the specifications of the moving partition device 10 such as the weight of the panel 260. It can be appropriately changed according to the above.

(Spacer 140)
The spacer 140 has a function for constantly keeping the distance between the fixing member 120 and the flat plate 150 constant and reducing the transmission of vibration and noise from the flat plate 150 to the fixing member 120. In order to achieve these functions, the spacer 140 is composed of a member having low elasticity, and in this embodiment is composed of hard rubber. According to the inventor's knowledge, the spacer 140 can use a hard rubber having a Shore hardness of about 60 or more in the usage situation as in the present embodiment. It is preferable to use a material having a hardness of about 60 to 80, and a material having a Shore hardness of 20 or more than that of the vibration isolator 130 is preferable.

  As shown in FIG. 2, the spacer 140 has a thin cubic shape, and the upper and lower surfaces are formed in a planar shape. A through hole 141 is formed in the spacer 140, and a bush 142 extending from the periphery of the through hole 141 in the axial direction of the through hole 141 is formed. The bolt shaft 161 of the bolt 160 passes through the through hole 141 and the bush 142. The bush 142 is configured to be inserted through the through hole 122 of the fixing member 120 and the through hole 131 of the vibration isolator 130, whereby the bolt shaft 161 is not in contact with the fixing member 120.

  The spacer 140 configured in this manner is disposed between the flat plate 150 and the fixing member 120, so that it is substantially elastically deformed even with a pressing force from the flat plate 150 due to tightening of the bolt 160 and the nut member 170. Absent. For this reason, the space | interval of the fixing member 120 and the flat plate 150 can be always kept constant. As a result, the flat plate 150 does not drop even after long-term use, and the mounting height of the hanger rail 110 does not change. Furthermore, since the spacer 140 is made of hard rubber, the transmission of vibration and noise transmitted from the bolt shaft 161 to the flat plate 150 is reduced.

  In addition, the material and shape of the spacer 140 of this embodiment are examples, and are not limited to this. As described above, if the spacer 140 has a function of constantly maintaining the distance between the fixing member 120 and the flat plate 150 and a function of reducing vibration and noise transmitted from the flat plate 150 to the fixing member 120, for example, The weight of the panel 260 can be changed as appropriate according to the specifications of the moving partition device 10.

(Flat plate 150)
As shown in FIG. 2, the flat plate 150 has a flat bottom surface that contacts the spacer 140, and a through-hole 151 through which the bolt shaft 161 of the bolt 160 passes. A nut member 170 is welded to the position of the through hole 151 at the top of the flat plate 150.

  In the above, the structure of the vibration isolator 100 for moving partitions of this embodiment was demonstrated. Next, the assembly process of the vibration isolator 100 for moving partitions of this embodiment will be described with reference to FIG.

  First, as shown in FIG. 3, the vibration isolator 130 is disposed between the mounting surface 111 of the hanger rail 110 and the mounted surface 121 of the fixing member 120. At this time, the vibration isolator 130 and the mounted surface 121 of the fixing member 120 are separated from each other. A flat plate 150 is arranged on the opposite side of the mounting surface 121 of the fixing member 120 from the vibration isolator 130 via a spacer 140. At this time, the bush 142 of the spacer 140 passes through the through hole 122 of the fixing member 120, and the tip of the bush 142 is inserted into the through hole 131 of the vibration isolator 130.

  Thereafter, the bolt shaft 161 of the bolt 160 from below the hanger rail 110 is connected to the through hole 113 of the hanger rail 110, the through hole 131 of the vibration isolator 130, the bush 142 and the through hole 141 of the spacer 140, and the through hole 151 of the flat plate 150. Are inserted so that the tip of the bolt shaft 161 is screwed into the nut member 170. Then, the bolt 160 is rotated as indicated by an arrow a in the figure, and the bolt 160 and the nut member 170 are tightened.

  By tightening the bolt 160 and the nut member 170, the hanger rail 110 is raised as shown in FIG. 4, and the upper surface of the vibration isolator 130 comes into contact with the mounted surface 121 of the fixing member 120.

  Even after this, by tightening the bolt 160 and the nut member 170, the height position of the hanger rail 110 with respect to the fixing member 120 can be adjusted. That is, when the bolt 160 and the nut member 170 are further tightened, the soft rubber vibration isolator 130 is pressed against the mounting surface 111 of the hanger rail 110 and elastically deformed. For this reason, the hanger rail 110 is indicated by a solid line in FIG. 5 from the position (the position indicated by the chain line in FIG. 5) when the upper surface of the vibration isolator 130 is in contact with the mounted surface 121 of the fixing member 120. It can be further raised to a different position.

  As described above, since the soft rubber vibration isolator 130 is deformed by being pressed against the mounting surface 111 of the hanger rail 110, the position of the hanger rail 110 is adjusted to some extent according to the tightening of the bolt 160 and the nut member 170. Can be adjusted. On the other hand, since the hard rubber spacer 140 is disposed between the flat plate 150 and the fixing member 120, the distance between the flat plate 150 and the fixing member 120 is kept constant.

  With the configuration described above, the space between the flat plate 150 and the fixing member 120 is kept constant by the spacer 140 by pressing the mounting surface 111 of the hanger rail 110 against the vibration isolator 130 by tightening the bolt 160 and the nut member 170. Meanwhile, the height position of the hanger rail 110 with respect to the fixing member 120 is adjusted. As described above, when the bolt 160 and the nut member 170 are tightened, the vibration isolator 130 is pressed to a certain extent by the mounting surface 111a of the hanger rail 110, but the pressure contact from the flat plate 150 is received by the spacer 140. The rail 110 can be stably fixed and the height can be adjusted.

(Effect of this embodiment)
As described above, according to this embodiment, the weight of the moving partition 200 is provided by providing the hard rubber spacer 140 between the flat plate 150 and the fixing member 120 so that the distance between them can be kept constant. Even if it is applied, the flat plate 150 does not descend. Thereby, the attachment height of the hanger rail 110 can be made constant. Further, since the height of the hanger rail 110 can be kept constant by the spacer 140, there is no step in the rail joint, and the mounting state can be stabilized even after long-term use.

  Further, since the spacer 140 is disposed between the flat plate 150 and the fixing member 120, the pressure contact by the flat plate 150 by tightening the bolt 160 is a hard rubber spacer that can keep the distance between the flat plate 150 and the fixing member 120 constant. 140. Thereby, it is not necessary to adjust the tightening amount of the bolt 160 according to the weight of the moving partition 200 applied to the flat plate 150, and can be made constant.

  Further, since the vibration isolator 130 made of soft rubber is provided between the hanger rail 110 and the fixing member 120, the flat plate 150, which is heavy on the moving partition 200, does not press the vibration isolator 130. For this reason, in order to eliminate the change of the height position of the hanger rail 110 by long-term use, the vibration isolator 130 is not pressed as much as possible. Therefore, the vibration isolating function of the vibration isolating material 130 is not impaired.

  By arranging the vibration isolator 130 between the hanger rail 110 and the fixing member 120 and the spacer 140 between the fixing member 120 and the flat plate 150, vibration and noise in the hanger rail 110 due to the travel of the panel 260 are prevented. It can be absorbed and relaxed by the vibration isolator 130.

  Further, since the spacer 140 is disposed between the flat plate 150 and the fixing member 120, there is no direct contact between the flat plate 150 and the fixing member 120, and therefore vibration and noise transmitted from the bolt shaft 161 to the flat plate 150. Can be relaxed with respect to the fixing member 120.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above embodiment, the vibration isolator 130 made of soft rubber has been described as an example of the vibration isolator, but the present invention is not limited to this. Any vibration-proof material can be adopted as long as it can absorb and mitigate vibration and noise in the hanger rail 110 due to the travel of the panel 260.

  Moreover, although the said embodiment demonstrated the spacer 140 comprised with hard rubber as an example of a spacer, this invention is not limited to this. Any spacer can be used as long as the distance between the flat plate 150 and the fixing member 120 can be kept constant (for example, a thermoplastic resin having a low elasticity, a thermosetting resin, a general-purpose plastic, a composite material, etc.). Can be employed.
