Description

  The present invention relates to a silencer structure of a guide rail, for example, a silencer structure attached to a guide rail of an opening / closing device such as a shutter.

  Conventionally, a guide rail of an opening / closing device such as a shutter has a belt-like shape to suppress the opening / closing operation of the opening / closing body, but also to eliminate the impact sound during the opening / closing operation and the wind noise due to the wind of the opening / closing operation. A muffler with brushed mohair was attached to the base.

  However, in the case of this silencer with mohair structure, the mohair will be worn out in the process of repeated opening and closing work, or the mohair will be deformed or “sagging” due to long-term use. There was a risk that the effect could not be obtained.

The following patent document 1 and patent document 2 are proposed with respect to such a problem.
In Patent Document 1, a silencer band is formed of a synthetic resin member extending along a guide rail, and the synthetic resin member is extended from the base portion to a base portion that engages with the guide rail. A structure constituted by an elastic contact portion that comes into contact is disclosed.

  In this way, by constructing the silencer band with a synthetic resin member having an elastic contact portion, it is possible to avoid problems such as mohair wear and “sagging” that were problems with the mohair structure. When opening and closing the body, it is possible to prevent the generation of wind vibration sound due to the wind of the wind at the time of closing while exhibiting a sufficient sliding effect.

  On the other hand, in Patent Document 2, in order to facilitate attachment / detachment to / from the guide rail, a contact portion that contacts the opening / closing body is formed of a flexible member, and the contact portion elastically contacts the opening / closing body. Thus, the structure which provides an elastic protrusion piece in the back side of a contact part is disclosed.

  Also in this structure, the problem of the mohair structure is solved by forming the silencer band with a synthetic resin member or the like. Moreover, in this structure, it is suggested that a contact part and an elastic protrusion piece are comprised with another raw material.

JP 2001-182461 A.

Japanese Patent Laid-Open No. 7-293159.

  However, in the case of the silence band structure of Patent Document 1, the elastic contact portion is a sliding portion that contacts the opening and closing body and is an elastic means that generates an elastic force. There was a possibility that the material could deteriorate due to sliding with the body and could not exhibit an appropriate elastic force for preventing the generation of wind noise.

  In order to solve this problem, it is conceivable that the sliding portion and the elastic means are configured separately as in the silence band structure of Patent Document 2.

However, the silencer structure of Patent Document 2 also has the following problems.
In the case of the silence band structure of Patent Document 2, since the contact portion that contacts the opening / closing body is integrally formed with the claw that engages the guide rail, the contact portion is oscillated and displaced by contact with the opening / closing body. In addition, there is a risk that the engagement between the guide rail and the claw is easily disengaged.

  To solve this problem, it can be considered that the elastic force of the elastic protrusion is increased so that the contact portion is less likely to swing and displace. However, the sliding resistance increases accordingly, and the opening / closing operability of the opening / closing body is increased. There is concern about the decline.

  Therefore, the present invention has a silencer structure that is attached to a guide rail of an opening / closing body, and can stably mute even if the initial elastic force is exhibited for a long time without increasing the elastic force. An object of the present invention is to provide a silencer band structure for a guide rail in which a band can be attached to a guard rail.

  A silencer band structure of a guide rail according to the present invention is a silencer band structure of a guide rail that is attached to a guide rail of an opening / closing body, and extends along the guide rail, and a sliding portion that contacts the opening / closing body; An elastic means that is located on the back side of the sliding portion and that gives an elastic force to the sliding portion, and a base portion that is fixed to the mounting portion in the guide rail with the elastic means fixed It is.

  According to the above configuration, the sliding portion extends along the guide rail and comes into contact with the opening / closing body, and the elastic means is located on the back side of the sliding portion and applies an elastic force to the sliding portion. Even if the sliding portion deteriorates due to sliding with the opening / closing body, the elastic force of the elastic means is not affected. For this reason, the elastic force which prevents generation | occurrence | production of a wind vibration sound can be exhibited over a long period of time.

  In addition, since the base portion is provided via the elastic means separately from the sliding portion, even if the sliding portion is oscillated and displaced, the base portion is not affected and can be prevented from being detached from the guide rail.

  In one embodiment of the present invention, the sliding portion is configured to have a substantially semicircular cross section.

  According to the above configuration, since the sliding portion has a substantially semicircular cross section, the contact area with the opening / closing body can be reduced as much as possible, so that sliding resistance can be further reduced, and the opening / closing of the opening / closing body can be reduced. Operation can be performed more smoothly.

  Further, even when the opening / closing body is inserted into the guide rail from a direction orthogonal to the guide rail, for example, in a maintenance operation, the sliding portion can easily perform the insertion operation.

  In one embodiment of the present invention, the elastic means is fixed at the center of the back surface of the sliding portion.

  According to the above configuration, by fixing the elastic means at the center of the back surface of the sliding portion, the elastic means always applies a certain elastic force to the sliding portion even if the sliding portion tilts and swings left and right. be able to.

  For this reason, even when the sliding portion tilts and swings left and right following the movement of the opening and closing body, the sliding portion can be brought into contact with the opening and closing body with a certain elastic force. Therefore, an effective silencing effect can be obtained.

  In one embodiment of the present invention, swing range defining means for defining the swing range of the sliding portion is provided.

  According to the above configuration, since the swing range of the sliding portion is defined by the swing range defining means, if the open / close body changes greatly, the follow-up beyond the swing range of the sliding portion is limited. Thus, it is possible to prevent the base portion of the silencer from being detached from the guide rail mounting portion.

  In addition, since the swing range is defined, the elastic force applied to the opening / closing body by the sliding portion can also be adjusted.

  In one embodiment of the present invention, the sliding portion is made of a hard synthetic resin, and the elastic means is made of a soft synthetic resin.

  According to the above configuration, the sliding portion is made of a hard synthetic resin and the elastic means is made of a soft synthetic resin, so that wear of the sliding portion can be reduced as much as possible, and an appropriate elastic force by the elastic means can be obtained. Can be secured.

  In one embodiment of the present invention, the elastic means is constituted by a substantially square cross section.

  According to the said structure, since the elastic means can be comprised by the substantially square cross section, the stroke which elastically displaces a sliding part can be enlarged, Therefore The followability with respect to a motion of an opening-closing body can be improved more.

  In one embodiment of the present invention, a notch is formed in the bent portion of the substantially square cross section.

  According to the said structure, since the notch part was formed in the bending part of a substantially square cross section, since a deformation | transformation of an elastic means arises in a bending part reliably, an elastic means can be elastically deformed more smoothly.

  According to this invention, since the elastic means is provided separately from the sliding portion, the elastic force of the elastic means is not affected, and the elastic force for preventing the generation of wind vibration noise can be exhibited for a long period of time. it can.

  In addition, since the base portion is provided separately from the sliding portion, even if the sliding portion is oscillated and displaced, the base portion is not affected and can be prevented from being detached from the guide rail.

  Therefore, it is possible to provide a guide rail silencer structure that can stably attach the silencer band to the guard rail without increasing the elastic force while exhibiting the initial elastic force for a long period of time. be able to.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a front view of a shutter device S in which the silence band structure of the present invention is adopted. In this figure, reference numeral 1 denotes a guide rail body attached to both left and right edges of an opening A of a building frame (not shown). The opposite edges of the shutter curtain 3 drawn from the shutter case 2 are opposed to each other. Is guided in the sliding groove 11.

  As shown in FIG. 2, the guide rail body 1 has a substantially U-shaped cross section, and an edge surface portion 12 that extends outward is formed on one side of the open side of the sliding groove 11. .

  Further, on the sliding surface of the shutter curtain 3 in the sliding groove 11, that is, on the side of the opposed inner side surface 13, a silencer mounting portion for attaching a later-described silencer band 4 to the open side of the sliding groove 11 respectively. 5 is formed.

  This silencer mounting part 5 is provided with a first fixing part 51 for fitting and fixing the base part 41 of the silencer band and a second fixing part provided on both sides thereof and extending from the sliding part 42 of the silencer band. And a fixed portion 52.

  In addition, although the closed space 15 partitioned off by the standing wall 14 is formed in the closed side of the sliding groove | channel 11, since it is not directly related to this invention, detailed description is abbreviate | omitted.

The structure of the silence band 4 attached to the silence band attachment part 5 will be described in detail with reference to FIGS.
The sound deadening band 4 extends along the guide rail body 1, and as described above, the base portion 41 that is fitted and fixed to the first fixing portion 51, the engaging portion 43 that is fitted and fixed to the second fixing portion 52, The elastic deformation portion 44 extends from the center of the base portion 41 toward the shutter curtain 3 side, and the sliding portion 42 that contacts and slides on the shutter curtain 3.

  The aforementioned base portion 41 is formed of a flat plate member formed of HDPE (high density polyethylene), which is a hard synthetic resin material, and ensures rigidity that does not easily separate from the first fixing portion 51.

  The elastic deformation portion 44 is composed of a plate member having a substantially square cross section formed of EVA (ethylene vinyl acetate copolymer) which is a soft synthetic resin material. Unlike the base portion 41, the elastic deformation portion 44 is subjected to a load. Is set to deform easily.

  The elastic deformation portion 44 includes a notch portion 45a in a coupling portion 44a with the base portion 41, a bent portion 44b in a dogleg shape, and a coupling portion 44c between the sliding portion 42 and the base portion 41 so that the deformation can be performed more smoothly. , 45b, 45c. Of these, the notch 45 b provided in the bent portion 44 b functions to adjust the elastic force of the elastic deformation portion 44, and has an important function for obtaining the silencing effect of the silencing band 4. On the other hand, the notches 45a and 45c provided in the coupling portion 44a with the base portion 41 and the coupling portion 44c with the sliding portion 42 are used when the sliding portion 42 is displaced rearward (in a direction away from the shutter curtain 3). In addition, the sliding portion 42 has a function of preventing tilting under the influence of the deformation of the elastic deformation portion 44 so that the sliding portion 42 can be smoothly translated backward.

  The sliding portion 42 is composed of a plate member having a semi-elliptical cross section formed of HDPE, which is a hard synthetic resin material. Unlike the elastic deformation portion 44, the sliding portion 42 is not easily deformed even when it comes into contact with the shutter curtain 3. It is set as follows. Therefore, as shown in FIG. 3, even if it contacts the protrusion 31 of the shutter curtain 3, the sliding portion 42 itself is not deformed, and the load is transmitted to the elastic deformation portion 44. .

  Further, the sliding portion 42 is set so that the opening and closing operation of the shutter curtain 3 can be performed more smoothly by smoothing the sliding surface 42a that contacts the shutter curtain 3 and reducing the frictional resistance.

  Further, since the sliding portion 42 is made of hard synthetic resin as described above, there is little risk of wear.

  The aforementioned engaging portion 43 is also formed of HDPE, which is a hard synthetic resin material, like the sliding portion 42. The reason why the engaging portion 43 is made of a hard synthetic resin material is to secure rigidity that does not easily separate from the second fixing portion 52, as in the case of the base portion 41.

  The second fixing portion 52 to which the engaging portion 43 is fixed has a larger fitting space than the first fixing portion 51. This is to ensure the amount of rocking displacement of the sliding portion 42 described above.

  That is, a range in which the sliding portion 42 can be oscillated and displaced can be obtained by setting the range L between the lower base 52a and the upper wall 52b of the second fixing portion 52 (see FIG. 2) to a free movement range of the engaging portion 43. It is secured.

  By securing the swing range of the sliding portion 42 in this manner, even when the shutter curtain 3 fluctuates due to wind pressure, the sliding portion 42 reliably moves its displacement backward. It can be absorbed (see the dotted line state shown in FIG. 4) to prevent wind noise.

  Further, since the engaging portions 43 are provided on the left and right sides, when the shutter curtain 3 is inclined by receiving a certain load, the sliding portion 42 is inclined following the inclination of the shutter curtain 3. (Refer to the two-dot chain line state shown in FIG. 4). Therefore, it is possible to prevent the generation of noise such as an impact sound by following various movements of the shutter curtain 3.

  The reason why the sliding portion 42 can smoothly move in the inclined direction is that the elastic deformation portion 44 is fixed to the center 42b on the back side of the sliding portion 42 at one point as described above.

  Further, since the position of the engaging portion 43 is regulated by the lower bottom 52a and the upper wall 52b of the second fixing portion 52 as described above, it does not follow the movement of the shutter curtain 3 beyond a predetermined amount. Is set to For this reason, when the shutter curtain 3 moves greatly, the position of the silencer 4 is fixed, and the silencer 4 is configured not to be detached from the silencer attachment part 5.

Next, the operation and effect of the present embodiment configured as described above will be described in detail.
Thus, the silence band 4 of the present embodiment is a guide rail silence band 4 attached to the guide rail body 1 of the shutter curtain 3, extends along the guide rail body 1, and extends to the shutter curtain 3. The sliding portion 42 that comes into contact, the elastic deformation portion 44 that is located on the back side of the sliding portion 42 and applies an elastic force to the sliding portion 42, and the elastic deformation portion 44 is fixed, and the guide And a base portion 41 to be mounted on the silencer mounting portion 5 of the rail body 1.

  According to the above configuration, the sliding portion 42 extends along the guide rail body 1 and comes into contact with the shutter curtain 3, and the elastic deformation portion 44 is located on the back side of the sliding portion 42, and the sliding portion 42. Therefore, even if the sliding portion 42 deteriorates due to sliding with the shutter curtain 3, the elastic force of the elastic deformation portion 44 is not affected. For this reason, the elastic force which prevents generation | occurrence | production of a wind vibration sound can be exhibited over a long period of time.

  Further, since the base portion 41 is provided via the elastic deformation portion 44 separately from the sliding portion 42, no matter how much the sliding portion 42 is oscillated and displaced, the base portion 41 is not affected, and the guide rail main body is not affected. There will be no problem of leaving from 1.

  Therefore, according to this embodiment, it is possible to stably attach the silencer 4 to the guardrail body 1 over a long period of time while exhibiting the initial elastic force and without increasing the elastic force. it can.

  In this embodiment, the sliding portion 42 is configured to have a semi-elliptical cross section.

  According to the above configuration, since the sliding surface 42 has a semi-elliptical cross section, the contact area with the shutter curtain 3 can be reduced as much as possible, so that the sliding resistance can be further reduced. 3 can be opened and closed more smoothly.

  Further, even when the shutter curtain 3 is inserted into the sliding groove 11 from a direction orthogonal to the guide rail body 1 for maintenance work or the like, there is no possibility that the sliding portion 42 hinders the insertion work. Can do.

  Note that substantially the same effect can be obtained by using a semicircular cross section or a cross sectional shape with rounded rectangular corners instead of the semielliptical cross section.

  Further, in this embodiment, the elastic deformation portion 44 is fixed to the rear side center 42 b of the sliding portion 42.

  According to the above configuration, by fixing the elastic deformation portion 44 to the back side center 42b of the sliding portion 42, even if the sliding portion 42 tilts and swings left and right, the elastic deformation portion 44 always has a constant elastic force. Can be continuously applied to the sliding portion 42.

  For this reason, even when the sliding portion 42 tilts and swings left and right following the movement of the shutter curtain 3, the sliding portion 42 can be brought into contact with the shutter curtain 3 with a certain elastic force. Therefore, an effective silencing effect can be obtained.

  In this embodiment, the engagement portion 43 and the second fixing portion 52 are provided in order to define the swing displacement range of the sliding portion 42.

  According to the above configuration, the swinging displacement range of the sliding portion 42 is defined by the engaging portion 43 and the second fixing portion 52. Therefore, when the shutter curtain 3 changes greatly, the sliding portion 42 By limiting the follow-up beyond the swing displacement range, it is possible to prevent the base portion 41 of the silence band 4 from being detached from the silence band mounting portion 5 of the guide rail body 1.

  Further, since the swing displacement range is defined, the elastic force that the sliding portion 42 applies to the shutter curtain 3 can also be adjusted.

  In this embodiment, the sliding portion 42 is made of HDPE, which is a hard synthetic resin material, and the elastic deformation portion 44 is made of EVA, which is a soft synthetic resin material.

  According to the above configuration, the sliding portion 42 is made of a hard synthetic resin and the elastic deformation portion 44 is made of a soft synthetic resin, so that the wear of the sliding portion can be reduced as much as possible. An appropriate elastic force due to the deforming portion 44 can be ensured.

  The material is not limited to HDPE or EVA, and the same effect as in the present embodiment can be obtained as long as the elastically deforming portion is made of a soft material as compared with the sliding portion. be able to.

  Further, in the present embodiment, the description is made with the material made of different materials. However, even if the material is the same, the same effect can be obtained as long as the elastically deforming portion is more easily deformed than the sliding portion. be able to.

  Further, in this embodiment, the elastic deformation portion 44 is constituted by a substantially square cross section.

  According to the above configuration, by configuring the elastic deformation portion 44 with a substantially square cross section, the stroke of the elastic displacement of the sliding portion 42 can be increased, so that the followability to the movement of the shutter curtain 3 can be further improved. it can.

  Further, in this embodiment, the notched portion 45 b is formed in the bent portion 44 b of the elastically deformable portion 44.

  According to the above configuration, since the notched portion 45b is formed in the bent portion 44b of the elastic deformable portion 44, the elastic deformable portion 44 is surely deformed in the bent portion 44b, so that the elastic deformable portion 44 is elastically deformed more smoothly. Can be made.

That is, a silencer band 4A similar to the above-described embodiment is adopted for a guide rail body 1A having a general silencer mounting part 5A having no second fixing part.

  Since the sound deadening band 4A does not have an engaging portion, it is not possible to define a range in which the sliding portion 42 can be swung and displaced. However, since the structure of the guide rail main body 1A can be made simple and versatile, it can be said that the structure is effective when considering the production cost.

  In this embodiment, as in the above-described embodiment, the silencing effect can be maintained for a long time, and other effects can be obtained in the same manner.

FIG. 6 shows a silencer band 4B of a guide rail of still another embodiment.
