The present invention relates to a grip member of an overturn preventing device and the overturn preventing device.
Patent Document 1 discloses a conventional overturn preventing device. This overturn preventing device includes a damper and a pair of bases. The damper is mounted between a top surface of a piece of furniture installed on a floor and a ceiling. The damper has two ends respectively supported by the paired bases to be rotatable about rotation axes. One of the bases abuts against the top surface of the furniture and the other base abuts against the ceiling. As a result, in this overturn preventing device, when the furniture is tilted by shaking of earthquake or the like in a direction parallel to a rotation direction of the damper, the damper is rotated about the rotation axes relative to the bases so that the bases can be maintained in abutment against the top surface of the furniture and the ceiling respectively. As a result, this overturn preventing device can apply a damping force of the damper to the furniture thereby to suppress the tilt of the furniture and prevent the furniture from
Patent Document 1: Japanese Patent Application Publication No. JP 2015-6330
Once the damper of the overturn preventing device of Patent Document 1 has been mounted between the top surface of the furniture and the ceiling, the ceiling side base is pressed against the ceiling by a strong force due to a spring property in a direction of extension by the gas pressure of compressed gas, with the result that the ceiling side base is held with a strong friction force. Therefore, when the ceiling side base is to be moved after the mounting for some reason, for example, when the installation position of the ceiling side base is to be finely adjusted, the ceiling side base needs to be moved downward against the biasing force of the damper so that a frictional force is prevented from being generated between the ceiling side base and the ceiling, and then the ceiling side base needs to be moved further. However, in the first place, it is difficult for a worker to directly hold and downwardly move the base installed at a high position near the ceiling. It is extremely difficult for the worker to accurately move the base to a desired location while carrying out such a burdensome work.
The present invention was made in view of the above-described circumstances in the conventional art and has an object to provide a grip member and an overturn preventing device provided with the grip member which can allow the ceiling side base to be relocated easily even after the overturn preventing device has been mounted between the top surface of an article and the ceiling.
A grip member in accordance with the present invention is attached to an overturn preventing device including a damper to be mounted between a top surface of an article installed on an installation surface and a ceiling, and a pair of bases respectively coupled to both ends of the damper. One of the bases abuts against the top surface of the article and the other base abuts against the ceiling. The grip member includes a locking part locked to the base at the ceiling side and a grip part connected to the locking part and drooping below the ceiling side base in a mounted state in which the ceiling side base is in abutment, against the ceiling.
In the grip member of the present invention, when the overturn preventing device is mounted so that one of the bases abuts against the top surface of the article and the other base abuts against the ceiling, the grip part connected to the locking part droops below the ceiling side base with the locking part being locked to the ceiling side base. Since the grip member is thus constructed, when having a desire to change the location of the ceiling side base, the worker can easily detach the base from the ceiling against the biasing force of the damper by pulling the grip part downward while gripping the grip part drooping downwardly. The ceiling side base can be moved to a desired location by moving the grip part while a frictional force is prevented from being generated by such a pulling operation. In particular, when the location of the ceiling side base is to be changed, the worker can operate a portion located nearer than the ceiling side base, and moreover, the worker can operate while gripping the drooping grip part. As a result, the worker can easily do the work in a posture allowing the worker to apply a strong force.
Accordingly, the grip member of the invention can allow the ceiling side base to be relocated easily even after the overturn preventing device has been mounted between the top
The ceiling side base may include a body and a rotating shaft member which is assembled to the body and rotatably holds one of the ends of the damper. The rotating shaft member may have two ends respectively protruding at both sides of a central axis of the damper along a direction intersecting with the central axis. A pair of the locking parts may be locked to the ends of the rotating shaft member respectively. In the case where the paired locking parts are respectively locked to both ends of the rotating shaft member which rotatably holds the end of the damper, when the grip part connected to the locking parts is pulled downward, the pull force efficiently acts for compression of the damper. Accordingly, the pull force applied to the grip part required to detach the ceiling side base from the ceiling can be reduced more, with the result, that the relocation operation can be carried out more easily.
The grip member may include connecting parts connected be caused to come close to each other so that a distance therebetween is shorter than a distance between the locking parts, thereby forming a narrowed part. The grip part may be formed into an annular shape while located below the narrowed part, in the mounted state in which the ceiling side base is in abutment against the ceiling. When the grip part is thus formed into an annular shape, the worker can easily grip the grip part and easily apply the downward pull force. Furthermore, the narrowed part is located between the paired locking parts and the grip part in the mounted state in which the ceiling side base is in abutment against the ceiling. Accordingly, when the grip part is pulled downward, the paired locking parts are subjected not only to the downward force but also to a force applied in the direction such that, the locking parts come close to each other. As a result, the paired locking parts are rendered less likely to be detached outwardly from, the respective ends of the rotating shaft member.
The grip member may be made of an elastically deformable material and be formed into an elongated, shape in an extended state. The grip member may be formed with one of the locking parts at a location near one of two longitudinal ends thereof and formed with the other locking part at a location near the longitudinal other end thereof. The grip member may be formed with a through hole part located between the locking parts. The grip member may such that, either connecting part is passed through the through hole part. According to this configuration, an annular grip part, which is easy to grip can be constructed with the simple structure such that the locking parts are respectively formed near both ends of the elastically deformable elongated material and the through hole part is formed therebetween. Furthermore, the paired locking parts can be rendered less likely to be detached.
The grip member may further include a first attachment member including the locking part and the grip part. The first attachment member may be attached to the ceiling side base. The grip member may further include a second attachment member including a second locking part locked to the article side base and a second grip part connected to the second locking part. The second attachment member may be attached to the article side base. Furthermore, the grip member may include a coupling member coupling the first and second attachment members. In the grip member thus constructed, the first and second attachment members and the coupling member may be connected to one another between the ceiling side base and the article side base, thereby holding the damper in a contracted state in which the damper has a desired length.
As the result of use of this grip member, the damper of the overturn preventing device can be held in the contracted state with a desired length. When the coupling member is loosened or cut after one of the bases of the overturn preventing device in the above-described contracted state has been placed on the top surface of the article, the damper is extended so that the other base abuts against the ceiling, whereby the mounting work can be finished. As the result of realization of such a mounting manner, the worker need not carry out the mounting work while contracting the damper above the article, so that the overturn preventing device can easily be mounted between the top surface of the article and the ceiling. Furthermore, when the respective bases are mounted at the ceiling side and the article side by loosening or cutting the coupling member, the grip part connected to the locking part droops below the ceiling side base. Accordingly, the ceiling side base can easily be relocated after the mounting by moving the grip part while holding and pulling the grip part. On the other hand, the second attachment member remains attached to the article side base. Accordingly, when the article side base is to be relocated. It is possible to operate while griping the second grip part of the second attachment member so as to pull up and move the article side base. Accordingly, the work of adjusting the location of the article side base can also be rendered easier. Furthermore, after the mounting has been carried out by loosening or cutting the coupling member, the first and second attachment members respectively remain attached to the ceiling side and article side bases. Accordingly, the overturn preventing device can be set again into the contacted state by coupling the first and second attachment members so as to come close to each other using the above-mentioned coupling member or a new member. In other words, the mounting work in reinstallation of the overturn preventing device can also be rendered easier.
Furthermore, an overturn preventing device may include the grip member in accordance with the invention, a damper and a pair of bases. According to the construction, the overturn preventing device which can allow the ceiling side base to be easily relocated can be realized.
Here, the article includes furniture, a bed having a plurality of beds connected to each other in the up-down direction, large sized televisions, refrigerators, bookshelves, showcases, server racks, and the like all of which have a possibility of being overturned by shaking of earthquake or the like.
A first embodiment of the overturn preventing device of the present invention will be described with reference to the drawings.
At least one overturn preventing device 1 of the first embodiment is mounted between a top surface of a piece of furniture F and a ceiling C, as illustrated in
The overturn preventing device 1 includes a damper 10, a pair of bases 30A and 30B, a fall preventing part 50, and an angle regulator 70, as illustrated in
The damper 10 has a cylinder 11, a rod guide (not illustrated), a piston (not illustrated), a rod 13, and two joints 15 respectively provided on both ends of the damper 10. The cylinder 11 is bottomed and has a cylindrical shape. The rod guide closes an opening of the cylinder 11. The piston is slidably inserted in the cylinder 11. The rod 13 has a proximal end connected to the piston. The rod 13 is inserted through the rod guide, so that a distal end thereof protrudes out of the cylinder 11. A hydraulic fluid and a compressed gas are enclosed in the cylinder 11. Each joint 15 is formed by bending a fiat plate-shaped metal fitting as illustrated in
The damper 10 is a compression damper in which a damping force generated during an extending operation is smaller than a damping force generated during a contracting operation. The extending operation of the damper 10 refers to an operation which increases an amount of protrusion of the rod 13 out of the cylinder 11 and the length of the damper 10. The contracting operation of the damper 10 refers to an operation which reduces an amount of protrusion of the rod 13 out of the cylinder 11 and the length of the damper 10. An expansion force of the compressed gas enclosed in the cylinder 11 works in an extension direction of the damper 10.
The following will describe a mechanism of generating a damping force by the damper 10. Since the mechanism has a known structure, diagrammatic representation is eliminated. The cylinder 11 has an interior divided by the piston into a rod side pressure chamber in which the proximal end of the rod 13 is housed and a counter-rod side pressure chamber. The piston is formed with an orifice which is a throttle valve communicating between both pressure chambers. The orifice functions as a damping force generator which applies resistance to a flow of the hydraulic fluid between the rod side pressure chamber and the counter-rod side pressure chamber with the extending/contracting operation of the damper 10. Furthermore, the piston is formed with a communication path communicating with both pressure chambers via a check valve. The check valve allows the hydraulic fluid to flow from the rod side pressure chamber to the counter-rod side pressure chamber and blocks reverse flow of the hydraulic fluid. Accordingly, the damper 10 has two flow paths of the hydraulic fluid from the rod side pressure chamber to the counter-rod side pressure chamber during the extending operation, that is, one flow path including the orifice and the other flow path including the communication path. On the other hand, the damper 10 has only one flow path of the hydraulic fluid from the counter-rod side pressure chamber to the rod side pressure chamber through the orifice during the contracting operation. Accordingly, the damping force generated by the damper 10 during the extending operation is smaller than the damping force generated by the damper 10 during the contracting operation.
The paired bases 30A and 30B are respectively a first base 30A to which the joint 15 connected to the bottom of the cylinder 11 is coupled and a second base 30B to which the joint 15 connected to a distal end of the rod 13 is coupled, as illustrated in
The base body 31 has a rectangular outer shape in a planar view as viewed from above in a state where the first base 30A is placed in abutment on the top surface of the furniture F. Hereinafter, a direction in which a long side in the outer shape of the base body 31 extends in this planar view will be referred to as “a long side direction” and a direction in which a short side extends will be referred to as “a short side direction”. Furthermore, in a side view of the first base 30A as viewed, in the short side direction in the state where the first base 30A is placed in abutment on the top surface of the furniture F, the base body 31 has a lower edge which extends straightforward in parallel to the top surface of the furniture F and an upper edge which upwardly bulges from, both sides of the lower edge thereby to have an arc-shaped outer shape (refer to
In the first base 30A placed in abutment on the top surface of the furniture F, the base body 31 has a groove 41 which is formed in an upper surface thereof and extends in the long side direction (a right-left direction as viewed in
The groove 41 has the paired convex portions 43 which are formed at a central part thereof in the long side direction to protrude from the bottom 41A and both inner wall surfaces 41B of the groove 41, as illustrated in
A pair of locked holes 49 is formed in the bottom 41A of the groove 41 as illustrated in
In the first base 30A placed in abutment on the top surface of the furniture F, the base body 31 has recesses 42 respectively formed in both sides of the groove 41 in the middle in the long side direction. The recesses 42 are each open upward and outward with respect to the short side direction. The recesses 42 each have a side, in which the insertion hole 43B formed through the convex portion 43 is open. A head 45A of the bolt 45 and the nut 47 screwed onto the bolt 45 which will be described, later are respectively disposed in the recesses 42. The recesses 42 are formed to be upwardly spread in the long side direction so that tools can be fitted with the bolt head 45A and the nut 47 from above.
The base body 31 is hollow as illustrated in
The rotating shaft member includes the bolt 45 inserted from one of the insertion holes 43B of the base body 31 and the nut 47 screwed onto the shaft part 45B of the bolt 45, as illustrated in
bush 35 is substantially cylindrical in shape as illustrated in
The central part of the bush 35 has an inner diameter slightly larger than an outer diameter of the shaft part 45B of the bolt 45. Both ends of the bush 35 have inner peripheral surfaces 35C the diameters of which are outwardly enlarged. Accordingly, the bush 35 is rotatable about the shaft part 45B of the bolt 45. Furthermore, the bush 35 is inclinable with respect to the shaft part 45B of the bolt 45 to the extent that the inner peripheral surfaces 35C of both ends thereof having enlarged diameters abut against an outer peripheral surface of the shaft part 45B of the bolt 45. In other words, the damper 10 with the bush 35 attached to the joint 15 is rotatable about the shaft part 45B of the bolt 45 and swingable in a direction intersecting the rotation direction. More specifically, the damper is swung due to the dimensional allowance and the enlarged diameters of the inner peripheral surfaces 35C. Furthermore, by the elastic deformation of the bush 35, the damper 10 can be swung more largely in the direction intersecting the rotation direction.
The slip preventing part 37 is made of rubber, for example, than the outer shape of the base body 31 (a rectangular shape), and is substantially fiat in shape, as illustrated in
At the portions where the damper 10 and the bases 30A and 30B are coupled, the bushes 35 are respectively rotatable in
The fall preventing part 50 is formed by bending a flat band-shaped metal, or formed of a resin, as illustrated in
The fall preventing part 50 is attached to the first base 30A placed in abutment on the top surface of the furniture F as illustrated in
In a state of being attached to the base body 31 of the first base 30A, the coupling part 51 of the fall preventing part 50 extends along the groove 41 formed in the base body 31 and the other end of the coupling part 51 is located outside an outer edge of the first base 30A (an outer edge of the slip preventing part 37 of the first base 30A). The drooping part 53 droops from the other end of the coupling part 51 and extends downward slightly outside the outer edge of the slip preventing part 37 of the first base 30A. The fall preventing part 50 is disposed between the wall surface W and the rear surface of the furniture F below the first base 30A.
The angle regulator 70 is detachably attached to the first base 30A placed in abutment, on the top surface of the furniture F as illustrated in Figs, 1, 2, and 6. As a result, the angle regulator 70 can be detached from the first base 30A during the packaging of the overturn preventing device or in other cases so that the overturn preventing device is prevented from bulking. In a state of being attached to the first base 30A, the angle regulator 70 has a regulating part 71 which, extends substantially vertically, and a support part 73 which is provided to be continuous from a lower part of the regulating part 71 and prevents the regulating part 71 from being inclined. The rectangular in shape. When the angle regulator 70 is attached to the first base 30A placed in abutment on the top surface of the furniture F, one of short side ends of the regulating part. 71 serves as a receiving part 71A located at an upper end. And, the other short side end is located at a lower end and serves as the insertion part 71B which is inserted into the locked hole 49 of the base body 31 located at the side away from the wall surface W.
The regulating part 71 causes the cylinder 11 of the damper 10 to abut against the receiving part 71A thereby regulating the damper 10 so as not to fall in excess of the inclined state. An inclination angle of the damper 10 preferably ranges from 15°to 25°. The receiving part 71A is upwardly open and curved so as to be downwardly recessed at a central part thereof so that abort one third of the outer periphery of the cylinder 11 abuts thereagainst. Thus, since the cylinder 11 is not held tightly by the receiving part 71A, the movement of the damper 10 is not restrained when the furniture F is tilted, or shaken by shaking of earthquake or the like. In other words, in this overturn preventing device, the damper 10 is rotatable about the rotation axes relative to the bases 30A and 30B and swingable in the direction intersecting the rotation direction, when the furniture F is shaken or tilted by shaking of earthquake or the like.
The insertion part 71B has inclined surfaces 71C respectively formed by cutting out both side corners of the short side in the long side direction so as to become thinner toward a distal end thereof, as illustrated in
The support part 73 includes a first support, part 73A and a second support part 73B. The first support part 73A has the same width as the regulating part 71 and is a flat plate extending in a direction perpendicular to the regulating part 71. The first support part 73A abuts against the bottom 41A of the groove 41 formed in the base body 31 when the insertion part 71B of the regulating part 71 is inserted into the locked hole 49 of the base body 31 of the first base 30A. The second support part 73B is a flat plate which has an isosceles right triangle shape and is coupled to a corner between the first support part 73A and the regulating part 71. In more detail, the second support part 73B has two sides having an equal length which are respectively coupled to a side surface of the first support part. 73A and a side surface of the regulating part 71, thereby supporting the regulating part 71 so that the first support part 73A and the regulating part 71 are perpendicular to each other.
Next, the fixing cord 119 will be described. The overturn preventing device 1 is provided with the fixing cord 190 which holds the damper 10 in a contracted state in which the damper 10 has a desired length, as illustrated in
The band member 110 serves as an example of the grip member and includes locking hole parts 112A and 112B serving as locking parts locked to the ceiling side second base 30B as illustrated in
As described above, the second base 30B located at the ceiling side includes a base body 31 serving as an example of the body, and a rotating shaft member (a bolt 45 and a nut 47) which is assembled to the base body 31 and rotatably holds the end of the damper 10. The head 45A of the bolt 45 and the nut 47 respectively serving as both ends of the rotating shaft member respectively protrude at both sides of the central axis of the damper 10 along the direction intersecting with the central axis of the damper 10. Here, the central axis of the damper 10 designates a center line serving as a center of an axis of the rod 13 and its extended line, and the head 45A of the bolt 45 and the nut 47 protrude in a direction perpendicular to the central axis. As illustrated in
The band member 110 is made of an elastically deformable and more specifically, a resin material such as polypropylene, or the like. The band member 110 is formed into a band member which is elongated in an extended state and has a thin plate shape with a predetermined thickness as illustrated in
When the band member 110 is to be fixed to the second base 30B as illustrated in
In the intersecting state of the band member 110 in which the connecting part 118B is passed, through the elongated hole part 114, the locking hole part 112A is fitted with the nut 47 thereby to be locked, and the locking hole part 112B is fitted with the head 45A of the bolt 45 thereby to be locked. Thus, the band, member 110 is attached to the second base 30B in the intersecting state.
The grip part 130 is formed into an annular shape while located below the intersecting part 16 (the narrowed part) in against the ceiling C. A center side part of the band member 110 when the band member 110 is extended into an elongated shape as illustrated in
The coupling part 120 of the fixing cord 190 at the article side is disposed so as to couple the annular part (the grip part 180) of the band member 110 disposed in the intersecting state and the first base 30A, as illustrated in
The following will describe a manner of mounting the overturn preventing device 1. In the overturn preventing device 1 constructed, as described above, the damper 10 can be held in the contracted state by the fixing cord 190 in advance. After the overturn preventing device 1 has been placed on the top surface of the furniture F with the damper 10 being held in the contracted state as illustrated in
When the overturn preventing device 1 has been mounted between the ceiling C and the furniture F, the band member 110 forming a part of the fixing cord 190 droops from the second base 30B, as illustrated in
In the case where the overturn preventing device 1 is mounted between the ceiling C and the furniture F as illustrated in
On the other hand, if the second base 30B is not in contact 20 with the ceiling C at a desired location in the mounted state and 9 and needs to be relocated, the worker, for example, pulls the annular grip part 180 downward while holding the grip part 180. When the grip part 180 is pulled downward against the biasing 25 force of the damper 10, the second base 30B can be moved downward thereby to be detached from the ceiling C, with the result that the second base 30B can be made into a state where no frictional force is generated between the second base 30B and the ceiling C. Thus, the second base 30B can be moved to the desired location by moving the grip part 180 back and forth or right and left while being detached from the ceiling C. When the pull of the grip part 180 is finished at a desired location, the second base 30B abuts against the ceiling C near the desired location thereby to be positioned.
As described above, when the overturn preventing device 1 is mounted so that the first base 30A abuts against the top surface of the furniture F (the article) and the second base 30B abuts against the ceiling C, the locking hole parts 112A and 112B of the band member 110 are locked to the second base 30B. In this locked state, the grip part 180 connected to the locking hole parts 112A and 112B droops below the second base 30B. Since the overturn preventing device 1 is thus constructed, when having a desire to change the location of the second base 30B, the worker can easily detach the second base 30B from the ceiling C against the biasing force of the damper 10 by pulling the grip part 180 downward while gripping the grip part 180 drooping downwardly. The second base 30B can be moved to the desired location by moving the grip part 180 while a frictional force is prevented from being generated by the above-described pulling operation. In particular, when the location of the ceiling side base is to be changed, the worker can operate a portion located nearer than the second base 30B, and moreover, the worker can operate while gripping the drooping grip part 18. As a result, the worker can easily do the work in a posture allowing the worker to apply a strong force.
Accordingly, according to the band member 110, the second base 303 located at the ceiling side can easily be relocated even after the overturn preventing device 1 has been mounted between the top surface of the furniture F (the article) and the ceiling C.
The second base 30B located at the ceiling side includes the base body 31 (the body) and the bolt 45 and the nut 47 (the rotating shaft member) which are assembled to the base body 31 and rotatably hold the end of the damper 10. The head 45A of the bolt 45 and the nut 47 respectively protrude at both sides of the central axis of the damper 10 along the direction intersecting with the central axis of the damper 10. The paired locking hole parts 112A and 112B (locking parts) of the band member 110 are locked to the head 45A of the bolt 45 and the nut 47 respectively. Thus, in the case where the paired locking hole parts 112A and 112B respectively locked to both ends of the rotating shaft member, when the grip part 180 connected to the locking hole parts 112A compression of the damper 10. Accordingly, the pull force applied to the grip part 180 required, to detach the ceiling side second base 30B from the ceiling can be reduced more, with the result that the relocation operation can be carried out more easily.
The band member 110 includes the connecting parts 118A and 118B connected to the respective locking hole parts 112A and 112B, and the connecting parts 118A and 118B are caused to come close to each other so that a distance therebetween is shorter than a distance between the paired locking hole parts 112A and 112B, thereby forming the intersecting part 116 (the narrowed part). The grip part 180 is formed into an annular shape while located below the intersecting part 116, in the mounted state in which the ceiling side base is in abutment, against the ceiling. When the grip part 180 is thus formed into an annular shape, the worker can easily grip the grip part 180 and easily apply the downward pull force. Furthermore, the intersecting part 116 (the narrowed part) is located between the paired locking hole parts 112A and 112B and the grip part 180 in the mounted state in which the ceiling side base is in abutment against the ceiling. Accordingly, when the grip part 180 is pulled downward, the locking hole parts 112A and 112B are subjected not only to the downward force but also to a force applied in the direction such that the locking hole parts 112A and 112B come close to each other. As a result, the paired locking hole parts 112A and 112B are rendered less likely to be detached outwardly from the head 45A of the bolt 45 and the nut 47 (both ends of the rotating shaft member).
The band member 110 is made of the elastically deformable material and formed into an elongated shape in the extended state. The band member 110 is formed with the one locking hole part 112A at a location near the longitudinal one end and formed with the other locking hole part 112B at a location near the longitudinal other end. The band member 110 is also formed with the elongated hole part 114 (the through hole part) located between the locking hole parts 112A and 112B. The band member 110 is attached to the second base 30B in the intersecting state such that the connecting part 118B is passed through the elongated hole part 114. According to this configuration, the annular grip part 180 which is easy to grip can be constructed with the simple structure such that the locking hole parts 112A and 112B are respectively formed near both ends of the elastically deformable elongated material and the elongated hole part 114 (the through hole part) is formed therebetween. Furthermore, the paired locking hole parts 112A and 112B can be rendered less likely to be detached.
Next, the overturn preventing device of a second embodiment will be described. A structure in which the article side coupling part 120 is eliminated from the overturn preventing device 1 of the first embodiment can be adopted as a configuration of the overturn preventing device of the second embodiment. The overturn preventing device of the second embodiment differs from, the overturn preventing device 1 of the first embodiment in that the article side coupling part 120 is eliminated and is the same in the other respects as the overturn preventing device 1 of the first embodiment.
In other words, the construction of the overturn preventing device of the second embodiment is the same as that illustrated in
When the overturn preventing device described above is to be mounted between the furniture F and the ceiling C, the paired bases 30A and 30B are moved in the approaching direction against, the biasing force of the damper 10 by one or more workers so that the damper 10 is put into the contracted state. While the damper 10 is maintained in the contracted state, the first base 30A is placed on the top surface of the furniture F, and the second base 30B is moved near a desired location on the ceiling C. Then, the bases 30A and 30B are caused to depart from each other so that the damper 10 is extended, with the result that the second base 30B can be caused to abut against the ceiling C. In this case, too, if the second base 30B is not in contact with the ceiling C at a desired location and needs to be relocated, the grip part 180 can be operated in the same manner as in the first embodiment.
The overturn preventing device of a third embodiment will be described with reference to
The overturn preventing device 301 also includes the damper 10 mounted between the top surface of the furniture F and the ceiling C and the paired bases 30A and 30B respectively coupled to both ends of the damper 10.
The band member 310 serving as an example of the grip member has a configuration such that a band-shaped member with a predetermined width and a predetermined thickness is formed into an annular shape. The band member 310 is made of an elastically deformable material, more specifically, a resin material such as polypropylene, or the like.
The slip preventing part 337 provided on the second base 30B is formed with a groove 337A extending in the short side direction and located near the central part of the second base 308 in the long side direction. A part of the band member 310 is disposed so as to be caught on the base body 31 while being housed in the groove 337A.
