Description

  The present invention relates to a telescopic guide structure that closes a gap formed by two adjacent housings and allows relative displacement of each housing such as an earthquake.

  In the case where a gap is interposed between the casings such as the two floors, the gap is closed by the cover body constituting the extendable guide structure in order to pass between the casings safely and smoothly. The telescopic guide structure can maintain a state where the gap is closed by allowing a relative displacement between the respective bodies due to an earthquake or the like.

  A floor joint cover body unit to which the first conventional technology of the telescopic guide structure is applied has a cover body that is mounted between two adjacent housings with a gap. One end of the cover body is locked to one housing, and the other end is supported to be movable to the other housing. The other end surface of the cover body is formed so as to be inclined upward as it separates from one housing. The other housing is formed with a guide surface that is inclined upward as it is separated from the other housing and is parallel to the other end surface of the cover. The floor joint cover device configured as described above avoids the floor surface by guiding the other end surface of the cover body upward by the guide surface when each housing is relatively displaced. Accordingly, the cover body can allow the relative displacement of the housing while maintaining the state where the gap is closed.

  The expansion joint device for floors to which the expansion / contraction guide structure of the second conventional technique is applied has a cover body that is mounted over two adjacent housings with a gap. To each housing, a support for supporting the both end portions in a movable manner is fixed. The cover body is provided with ball casters on the lower surfaces of both end portions thereof so that the cover body moves on the support body. A parting cover body projecting in a direction away from the cover body is provided at the upper ends of both ends of the cover body. Each support body is formed so that the vicinity of the parting portion is inclined so that the both end parts of the cover body can be guided to avoid the parting part of each case when the housings are relatively displaced in the direction of approaching each other. Since the cover body configured in this way can be moved on the support body by a ball caster, each casing is maintained while closing the gap when each casing is relatively displaced in the direction of approaching each other. Relative displacement can be tolerated.

  The floor joint cover device according to the first prior art is configured so that, when the respective housings are relatively displaced in directions close to each other, the other end portion of the cover body slides on the guide surface to avoid the parting portion. Since the other end portion of the body and the guide surface are opposed to each other, the contact area between the other end portion and the guide portion when sliding is large. When the contact area is increased, the small protrusions formed on the respective surface portions are caught and the sliding resistance of the cover body with respect to the guide surface is increased. For this reason, it becomes difficult for the cover body to move on the guide surface, the relative displacement of each housing is restricted, and it cannot be allowed smoothly. Further, a guide surface is formed on the other end surface of the cover body in parallel with the inclination. Therefore, problems such as difficulty in absorbing errors in adjustment and difficulty in adjustment occur.

  In the floor expansion joint device for floor according to the second prior art, ball casters are formed on the lower surfaces of both ends of the cover body in order to overcome the problems of the first prior art. Accordingly, the cover body can reduce the sliding resistance against the support body, but a large load is required when the inclined surface of the support body is raised by ball casting. For this reason, the relative displacement of each housing cannot be allowed smoothly. In the floor expansion joint device, the parting cover body is supported on the upper surface of the support body, and a level difference of the thickness of the parting cover body is generated between the upper surface of the parting cover body and the upper surface of the floor. When the height of the upper surface of the support is adjusted to eliminate this step, the parting cover body is caught by the parting part when the respective casings are relatively displaced in the direction of approaching each other. As a result, the relative displacement of each housing cannot be allowed smoothly. Moreover, it is necessary to provide a ball caster, and the structure is complicated.

  An object of the present invention is to provide a telescopic guide structure having a simple structure that can smoothly allow relative displacement of each housing.

The present invention includes a cover body that is mounted over two adjacent housings with a gap, one end portion is locked to one housing, and the other end portion is movably supported by the other housing,

A first guide surface that slopes upward as it separates from the first support surface with respect to the one housing, and a first guide surface that extends in a direction away from the one housing from an upper end of the first guide surface. 2 support surfaces, a rising surface rising from the second support surface, and a floor surface extending in a direction away from the one housing from the upper end of the rising surface,
At the other end of the cover body, a first auxiliary cover member is formed that protrudes in a direction away from the one housing and is supported by the second support surface,
The distance L1 between the end surface of the first auxiliary cover member that is farthest away from the other end portion of the cover body in the direction away from one housing and the rising surface, the end surface of the other end portion of the cover body, and the first guide The relationship with the distance L2 from the surface is selected as L1> L2 ,
The lower end of the other end portion of the cover body is a telescopic guide structure, wherein Rukoto formed to be inclined upward as it away from the skeleton of the one.

  According to the present invention, the cover body is mounted between two adjacent housings with a gap therebetween, one end portion is locked to one housing, and the other end portion is movably supported by the other housing. A first support surface, a first guide surface, a second support surface, a rising surface, and a floor surface are formed on the other housing. The first support surface extends in a direction away from the one housing from the upper end of the first opposing wall surface facing the one housing, and movably supports the other end of the cover body. The first guide surface is inclined upward as it separates from the first support surface with respect to the one housing. The second support surface extends from the upper end of the first guide surface in a direction away from the one housing. The rising surface rises from the second support surface. The floor surface extends from the upper end of the rising surface in a direction away from the one casing. A first auxiliary cover member that extends in a direction away from the one housing and is supported by the second support surface is formed at the other end of the cover body. The first auxiliary cover member is formed such that the relationship between the distance L1 and the distance L2 is selected as L1> L2. The distance L1 is the distance between the end surface and the rising surface that are the farthest away from the other end of the cover body of the first auxiliary cover member in the direction away from the one housing. The distance L2 is a distance between the end surface of the other end of the cover body and the first guide surface.

The cover body is mounted over two adjacent housings with a gap therebetween and covers the gap. One end of the cover body is locked to one housing, and the other end is movably supported by the other housing. Therefore, even if the two housings are relatively displaced, they follow the relative displacement of one housing. However, it is displaced relative to the other housing. Further, since the first guide surface that is inclined upward as it separates from the first support surface with respect to the one housing is formed, when the respective housings are relatively displaced in the approaching direction, the cover body is moved by the first guide surface. Guided upward. Since the relationship between the distance L1 and the distance L2 is L1> L2, when the cover body moves on the other housing, the first auxiliary cover member does not contact the rising surface and the rising surface can be avoided. it can.
Further, the lower end of the other end portion of the cover body is formed so as to be inclined upward as it separates from one housing. As a result, if the lower end of the other end of the cover body comes into contact with the upper end of the rising surface, the cover body is guided upward by the upper end of the rising surface and moved upward when the casings are relatively displaced in the direction of approaching each other. You will get on the surface.

In the present invention, the cover body includes a supported member that is formed at a position separated from the other end portion and is movably supported on the first support surface.
The supported member is formed such that a surface facing in a direction away from the one housing is inclined upward as the surface is separated from the one housing.

  According to the present invention, the cover body includes the supported member that is movably supported by the first support surface and is formed at a position separated from the other end portion. Therefore, the cover body includes the other end portion of the cover body. And the supported member are movably supported on the first support surface. The surface of the supported member that faces away from the one housing is formed so as to be inclined upward as it is separated from the one housing. As a result, when the surface of the supported member comes into contact with the upper end of the first opposing wall surface of the other housing and the respective housings are relatively displaced in a direction approaching each other, the supported member is moved upward by the upper end of the first opposing wall surface. You are guided and ride on the first support surface.

In the present invention, a second guide surface extending in a direction close to the one casing and rising upward is formed at one end parallel to the first opposing wall surface of the first guide surface and in a horizontal direction.
The cover body is a corner portion formed by the other end portion of the cover body, and an edge of the corner portion adjacent to the second guide surface is formed to be curved outward and convex toward the tip. It is characterized by that.

  According to the present invention, one end of the first guide surface in a direction parallel to and parallel to the first opposing wall surface is formed with a second guide surface extending in a direction adjacent to the one casing and rising upward. Is done. Therefore, a corner portion is formed by the first and second guide surfaces. Of the corner portion formed by the other end portion of the cover body, the corner portion close to the second guide surface is formed to be curved outward and convex toward the tip. When formed in this way, the corner of the cover body comes into contact with the position separated from the tip of the corner portion. Therefore, it is possible to prevent the so-called wedge effect that the corner portion bites into the tip of the corner portion.

In the present invention, a plurality of cover bodies are mounted adjacent to each other on the two casings,
The cover bodies adjacent to each other are characterized in that a second auxiliary cover member protruding in a direction approaching the adjacent cover body is formed at at least one of the opposing end portions facing each other. To do.

  According to the present invention, the plurality of cover bodies are respectively mounted adjacent to each other between the two housings. In the cover bodies adjacent to each other, a second auxiliary cover member that protrudes in a direction approaching the adjacent cover body is formed at at least one of the opposing end portions facing each other. The second auxiliary cover formed in this way interposes a gap between two cover bodies adjacent to each other. This suppresses contact between two cover bodies adjacent to each other.

  In the invention, it is preferable that the second auxiliary cover member is formed such that an edge facing the adjacent cover body is convex outward and curved in the vertical direction.

  According to the present invention, the second auxiliary cover member is formed such that the edge facing the adjacent cover body is outwardly convex and curved in the vertical direction. Since the edge of the second auxiliary cover member is formed in this way, the second auxiliary cover member can be avoided by guiding the member that contacts the edge upward or downward.

  According to the present invention, the cover body includes a cover body body formed in a lattice shape.

  According to the present invention, the cover body has a lattice-shaped cover body main body. Since the cover body main body is formed in a lattice shape, the cover body can transmit liquid such as rain and guide it to the gap.

  In the present invention, the other casing is a second opposing wall surface extending in a direction away from the first opposing wall surface from one horizontal end of the first opposing wall surface facing the one casing, An opposing second opposing wall surface, a third supporting surface extending in a direction away from one housing from the upper end of the second opposing wall surface, and continuing to the first supporting surface, and from one end of the third supporting surface to one housing A second guide surface that is inclined upward as it is separated from the first guide surface, and extends in a direction away from the upper end of the second guide surface with respect to one housing. The fourth support surface is further formed with a fourth support surface having a rising surface connected to one end thereof.

  According to the present invention, the other opposite wall surface, the third support surface, the second guide surface, and the fourth support surface are further formed on the other housing. The second opposing wall surface is a wall surface that extends from one horizontal end of the first opposing wall surface in a direction away from the first opposing wall surface and faces one of the casings. The first support surface is a surface that extends in a direction away from one housing from the upper end of the first opposing wall surface and movably supports the other end of the cover body. The second guide surface is a surface that is inclined upward as it separates from the third support surface with respect to one housing, and is discontinuous with the first guide surface. The fourth support surface is a surface that extends from the upper end of the second guide surface in a direction away from one housing and continues to the rising surface.

  In this way, the third support surface, the second guide surface, and the fourth support surface are formed, and the second guide surface is formed so as to be inclined. The other end of the body can move upward along the second guide surface. Thereby, the other end portion of the cover body can avoid the rising surface. Furthermore, since the first guide surface and the second guide surface are formed discontinuously, there are no corners formed when the first guide surface and the second guide surface are connected. This prevents the cover body from biting into the corners. This can prevent the wedge effect from occurring.

  According to the present invention, the cover body covers the gap formed between the two housings, and when each housing is relatively displaced in the direction of approaching and moving away from each other, the cover body follows the relative displacement of one housing and Relative displacement. When the cover body is displaced relative to the other housing, the other end of the cover body slides on the first guide surface, and the cover body is guided upward. Since the relationship between the distance L1 and the distance L2 is L1> L2, the first auxiliary cover member can be avoided without coming into contact with the rising surface when the cover body moves on the other housing. Thus, the cover body can cover the gap formed between the two housings. Since the first auxiliary cover member is prevented from coming into contact with the rising surface, the cover body can move smoothly on the other housing. Therefore, the telescopic guide structure can smoothly allow the relative displacement of each housing. Furthermore, since the first auxiliary cover member can be avoided without coming into contact with the rising surface, the first auxiliary cover member is not stretched and damaged even when a large load is applied to the cover body. With such a simple structure, the first auxiliary cover member can avoid the rising surface, so that the number of parts can be reduced as compared with the prior art. As a result, the manufacturing cost can be reduced.

In addition , since the lower end of the other end of the cover body is formed so as to be inclined upward as it separates from one housing, the lower end of the other end of the cover body should abut the upper end of the rising surface. Even when the respective casings are relatively displaced in the approaching direction, the cover body is guided upward by the upper end of the rising surface and rides on the upper end of the rising surface. Thus, the lower end of the other end of the cover body can be avoided by riding on the upper end of the rising surface. This prevents a problem that the lower end portion of the other end portion of the cover body is caught on the rising surface, and the relative displacement of each housing is allowed smoothly. Further, it is possible to prevent the lower end of the other end portion of the cover body from being damaged due to the above-described problem. Further, since the lower end of the other end portion of the cover body is formed to be inclined, it is not necessary to form the entire surface of the other end portion along the first guide surface as in the prior art. As a result, it is easier to absorb errors in the construction than in the past, and adjustment of the position of the cover body and the like is facilitated.

  According to the present invention, the cover body is movably supported on the first support surface by the other end portion of the cover body and the supported member, so that the first support surface is formed by the first and second conventional techniques. Small contact area. When the contact area is small, the small protrusions formed on the surfaces that come into contact with each other are less likely to be caught and the sliding resistance can be reduced. Therefore, the cover body can reduce the sliding resistance with respect to the first support surface as compared with the conventional case. Thereby, the relative displacement of each housing can be allowed smoothly.

  Further, a gap is partially generated between the cover body and the first support surface by the other end of the cover body and the supported member. Therefore, sand, dust and the like accumulated on the first support surface can be discharged into the gap through the gap. As a result, sand or the like accumulated between the cover body and the casing is quickly discharged into the gap, and clogging caused by deposits such as sand and dust is suppressed. As a result, the cover body can smoothly move on the first support surface, and the relative displacement of the two housings can be allowed smoothly.

  Furthermore, the supported member has a first opposing wall surface when a surface of the supported member facing away from one of the housings comes into contact with an upper end of the first opposing wall surface and the housings are relatively displaced in a direction approaching each other. It is guided upward by the upper end of the first board and rides on the first support surface. As a result, it is possible to prevent a problem that the supported member and the first opposing wall surface are caught, and the relative displacement of each housing can be allowed smoothly. Further, the surface can be prevented from being damaged due to the defect.

  According to the present invention, it is possible to prevent the so-called wedge effect from being generated when the corner portion of the other end portion of the cover body is engaged with the tip of the corner portion formed by the first and second guide surfaces. Thereby, even if the second guide surface is formed, the cover body can smoothly move the first guide surface. Therefore, the relative displacement of each housing can be allowed smoothly.

  According to the present invention, since the second auxiliary cover member is formed on the cover body, a gap is formed between the cover bodies adjacent to each other that are mounted between the two housings. This gap prevents the cover bodies from coming into contact with each other when the housings are relatively displaced in the direction of approaching and separating from each other. As a result, it is possible to prevent damage to the cover body and contact noise caused by contact between the cover bodies. It is possible to prevent a problem that the cover bodies are in contact with each other and get caught, and to allow the relative displacement of the respective housings smoothly.

  According to the present invention, the second auxiliary cover member is formed such that the edge facing the adjacent cover body is curved. Therefore, even when the member and the second auxiliary cover member are relatively displaced in the direction of approaching each other and the member comes into contact with the edge of the second auxiliary cover member, the member is guided upward or downward along the edge. Can be avoided. As a result, even if the plurality of cover bodies are relatively displaced in the direction in which they are close to each other, the second auxiliary cover member avoids by guiding the abutting member upward or downward, and is caught while the member is abutting. Prevent malfunctions. By preventing the problem of being caught, it is possible to smoothly allow relative displacement of the respective housings. Further, the end face of the second auxiliary cover member is prevented from being damaged due to the above problem.

  According to the present invention, since the cover body has the cover body body formed in a lattice shape, liquid such as rain can permeate and be guided to the gap. As a result, the cover body can guide the liquid to the gap while covering the gap, thereby preventing the human and the object from fitting into the gap and ensuring the drainage.

  According to the present invention, the other end of the cover body moves along the second guide surface, and the rising surface can be avoided. Since the first guide surface and the second guide surface are discontinuous in the other casing, the corner portion into which the corner portion of the cover body bites is not formed. This prevents the corner portion of the cover body from biting into the tip of the corner portion and prevents the wedge effect from occurring. Thus, when the other end of the cover body is displaced in the direction in which the two casings are close to each other, the rising surface formed at the upper end of the fourth support surface can be avoided and the first and second guide surfaces can be smoothly moved. can do. Therefore, the relative displacement of each housing can be allowed smoothly.

The guide member 9 is a plate-like member extending in the Y direction, and includes a guide portion 62 that is inclined upward as it goes rightward, and a support portion 63 that extends rightward from the upper end of the guide portion 62. . The guide member 9 has an end portion on the guide portion 62 side which is welded and fixed to the horizontal portion 58 of the second frame 51, and an end portion on the support portion 63 side is welded to the second rising portion 59 of the second frame 51. Fixed. The guide portion 62 is a swash plate that is inclined upward as it goes in the right direction. When the housings 3a and 3b are relatively displaced in directions close to each other, the guided portion 27 comes into contact. The guided portion 27 has a first guide surface 60 whose surface has an inclination angle with respect to the lower surface of the first supported member 21 and faces the guided portion 27 of the guide portion 62, that is, the first guide surface 64 which is the first guide surface. The two frames 51 are formed to have the same inclination angle θ with respect to the horizontal portion 58. However, the tilt angle is not limited to this, and the tilt angle of the guided portion 27 and the tilt angle θ of the guide surface 64 may be different from each other. The support part 63 is configured to support the first auxiliary cover member 6 on the upper surface in the mounted state, and to prevent a step between the upper surface of the first auxiliary cover member 6 and the floor surface 65 in this state. Specifically, the upper surface of the support portion 63 is disposed below the floor surface 65 by the thickness of the first auxiliary cover member 6 and is fixed to the second rising portion 59 of the second frame 51. A bent portion, which is a portion where the guide portion 62 and the support portion 63 are connected, is formed in parallel with the upper end of the second rising portion 59 of the second frame 51.

  In this way, the second housing 3b is formed with the opposing wall surface 36, which is the first opposing wall surface of the opposing wall portion 54 facing the first housing 3a, on the upper surface of the sliding plate 52 and the horizontal portion 58 of the second frame 51. A first support surface 73 is formed, a guide surface 64 that is a surface facing the first guided surface 60 of the guide portion 62 of the guide member 9 is formed, and a second support that is the upper surface of the support portion 63 of the guide member 9 is formed. A surface 75 is formed, and a rising surface 91 that is the surface of the second rising portion 59 of the second frame 51 is formed.

When the guide members 9 configured in this manner are relatively displaced in the direction in which the housings 3a and 3b are close to each other, the guided portion 27 slides to guide the cover body 5 upward to avoid the parting portion 66. Let The parting part 66 is synonymous with the parting part of the second casing 3 b formed by the second rising part 59 of the second frame 51. The guide member 9 is configured as follows in order to avoid the first auxiliary cover member 6 from coming into contact with the parting portion 66 when the casings 3a and 3b are relatively displaced in the direction in which they are close to each other. The first auxiliary cover member 6 in the mounted state has an end surface 26 (hereinafter sometimes referred to as “the front end 26 of the first auxiliary cover member”) (surface Q1) that is farthest from the cover body 5 in the first direction and a rising surface 91. The horizontal distance from the (surface Q2) is the distance L1, the horizontal distance between the lower end P1 of the first guided surface 60 and the guide surface 64 (surface P2) is the distance L2, and the second support surface 7 and the floor surface 65 are Is the distance ΔL. In order to avoid the first auxiliary cover member 6 without coming into contact with the parting part 66, the guided part 27 is in contact with the guide part 62 and the gap between the first auxiliary cover member 6 and the parting part 66 is avoided. It is necessary that a gap is formed. Therefore, the guide member 9 is formed such that the distance L1 is greater than the distance L2, that is, satisfies the relationship L1> L2. More specifically, in order to avoid the first auxiliary cover member 6 without coming into contact with the parting portion 66, the point Q1 is displaced by a distance L2 to the right with respect to the second casing 3b from the mounted state. In the state, that is, in a state where the cover body 5 is displaced from the attached state by the distance L2 in the right direction with respect to the second housing 3b, the first auxiliary cover member 6 needs to be displaced at least above the height ΔL. For this purpose, the cover body 5, the first auxiliary cover member 6 and the guide member 9 are
(L1-L2) sin θ> ΔL (1)
It is formed to satisfy. If comprised in this way, the guide member 9 can be avoided, without contacting the parting part 66 with the 1st auxiliary | assistant cover member 6. FIG. Furthermore, the first supported member 21 and the second supported member 28 are formed with a thickness equal to or greater than ΔL. As a result, the height of the guided portion 27 formed on the first supported member 21 is formed to be greater than or equal to ΔL.

  FIG. 10 is an enlarged cross-sectional view showing the relative displacement of the first and second supported members 21 and 28 of the cover body 5 with respect to the second housing 3b. In FIG. 8, the displacement in the vicinity of the second supported member 28 when the housings 3 a and 3 b are relatively displaced in the direction away from each other is indicated by a one-dot chain line, and the housings 3 a and 3 b are relatively displaced in the direction of approaching each other. The displacement in the vicinity of the first supported member 21 at this time is indicated by a two-dot chain line. When the casings 3a and 3b are displaced in directions away from each other, the cover body 5 is locked to the first floor 37a, and thus moves to the left with respect to the second casing 3b. The first and second supported members 21 and 28 slide leftward while being supported by the sliding plate 52. When the second supported member 28 slides leftward by the distance L3 or more from the mounted state, the second supported member 28 is detached from the sliding plate 52. The distance L3 is synonymous with the horizontal distance from the lower end of the second guided surface 29 to the left end in the X direction of the sliding plate 52 in the mounted state. When the second supported member 28 is detached to the left from the sliding plate 52, the cover body 10 is bent and the lower surface of the second supported member 28 is disposed below the first support surface 73. When the casings 3 a and 3 b are displaced from this state in the direction in which they are close to each other, the second supported member 28 comes into contact with the sliding plate 52. Since the second guided surface 29 is inclined, the second supported member 28 is guided to the first supporting surface 73 by the sliding plate 52 and can be smoothly run.

  When the casings 3a and 3b are relatively displaced in the direction in which they are close to each other, the cover body 5 is locked to the first floor 37a, and thus is displaced to the right with respect to the second casing 3b. The first supported member 21 slides rightward while being supported by the second support surface 73. When the second housing 3b is relatively displaced from the mounted state in a direction closer to the first housing 3a by the distance L2 or more, the guided portion 27 slides upward along the inclination of the guide surface 64. As a result, the first end portion 53 in the first direction moves upward and the cover body 5 is angularly displaced upward around the one end portion 8 in the first direction to be locked. When the cover body 5 is angularly displaced, the first auxiliary cover member 6 is formed so as to have a relationship of L1> L2, and thus can be avoided without contacting the parting portion 66. Further, when the second floor 37b is relatively displaced to the right by the distance L4 or more with respect to the first casing 3a from the mounted state, the guided portion 27 comes into contact with the parting portion 66. Since the first guided surface 60 is inclined in the cover body 5, the other end portion 53 in the first direction is guided upward by the parting portion 66, so that the part 5 can smoothly run on the floor surface 65 while avoiding the parting portion 66. Can do. The distance L4 is synonymous with the horizontal distance between the lower end of the first guided surface 60 and the upper end of the parting portion 66. In this way, when the cover body 5 and the first auxiliary cover member 6 are relatively displaced in the direction in which the housings 3a and 3b are close to each other, the parting portion 66 is avoided and the housings 3a and 3b are relatively displaced in the direction in which they are close to each other. Can be smoothly allowed to do.

  When the cover body 5 is angularly displaced upward about the first direction end portion 8 in this manner, the end plate 15 comes into contact with the first frame 41. Since the screw portion 40b is inserted into the bolt insertion hole 20 so as to be relatively displaceable, the cover body 5 is allowed to slide in the X direction with respect to the second housing 3b. Therefore, even when the end plate 15 is in contact with the first frame 41, the cover body 5 is allowed to be further angularly displaced upward by sliding displacement.

  Below, the effect which the expansion / contraction guide apparatus 1 comprised in this way has is demonstrated. According to the telescopic guide device 1 of the present embodiment, the cover body 5 covers the gap 4 formed between the two housings 3a and 3b, and when the housings 3a and 3b are relatively displaced in the direction of approaching and separating from each other. Then, following the relative displacement of the first housing 3a, it is displaced relative to the second housing 3b. When the cover body 5 is relatively displaced in the right direction with respect to the second housing 3b, the other end 53 in the first direction is guided upward along the guide surface 64 to avoid the parting portion 66. Since the relationship between the distance L1 and the distance L2 is selected as L1> L2, when the cover body 5 is displaced relative to the second housing 3b, the first auxiliary cover member 6 is brought into contact with the parting portion 66. Can be avoided without. The cover body 5 can cover the gap 4 formed between the two housings 3a and 3b. Since the cover body 5 prevents the first auxiliary cover member 6 from coming into contact with the parting portion 66, the cover body 5 can smoothly move on the other casing. Therefore, the relative displacement in the direction in which the respective housings 3a and 3b approach and separate from each other can be smoothly allowed. Further, since the first auxiliary cover member 6 is avoided without coming into contact with the parting portion 66, the first auxiliary cover member 6 is not stretched and damaged even when a large load is applied to the cover body 5. With such a simple structure, the first auxiliary cover member 6 can avoid the rising surface 91 and can smoothly allow the relative displacement of the two casings, so that the number of parts can be reduced as compared with the conventional structure. As a result, the manufacturing cost can be reduced.

  The first auxiliary cover member 6 is formed with a rising surface 91 rising from the support portion 63 so as to have a height approximately equal to the thickness of the first auxiliary cover member 6, thereby providing a step between the floor surface 65 and the upper surface of the first auxiliary cover member 6. Can be eliminated. As a result, the relative displacement of the respective housings 3a, 3b can be allowed smoothly, and the passage between the first auxiliary cover member 6 and the floor surface 65 can be performed more safely and smoothly.

  According to the telescopic guide device 1 of the present embodiment, since the first guided surface 60 is formed to be inclined upward as it goes rightward, the guided portion 27 should contact the parting portion 66 by any chance. Even when the respective casings 3a and 3b are relatively displaced in the approaching direction, they are guided upward by the upper end of the parting portion 66 and ride on the floor surface 65. Specifically, the first housing 3a is displaced upward relative to the second housing 3b, the first supported member 21 is supported by the support portion 63, and the housings 3a and 3b are displaced in a direction approaching each other. Then, the first direction other end portion 53 of the cover body 5 comes into contact with the parting portion 66. Since the guided portion 27 has a height of ΔL or more, the guided portion 27 comes into contact with the upper end of the parting portion 66, the cover body 5 is guided upward, and rides on the floor surface 65. In this way, the guided portion 27 is guided upward, and the parting portion 66 can be avoided. As a result, the problem that the guided portion 27 is caught with the parting portion 66 can be prevented, and the relative displacement of the respective housings 3a and 3b is allowed smoothly. Further, it is possible to prevent the guided portion 27 and the parting portion 66 from being damaged due to the above-mentioned problem. Further, since the first guided surface 60 is formed to be inclined upward, it is not necessary to form the entire surface of the other end portion 53 of the cover body 5 along the first guide surface 64 as in the prior art. As a result, it is easier to absorb errors in the construction than in the past, and adjustment of the position of the cover body 5 and the like becomes easier.

  According to the telescopic guide device 1 of the present embodiment, the guided portion 27 has a smaller contact area than the other end portion that slides on the guide surface of the floor joint cover device of the first prior art. When two objects slide, minute projections formed on the contact surfaces of the objects are caught and restrict sliding. Therefore, the contact area increases and the protrusions are caught more and the sliding resistance increases. In the telescopic guide device 1 of the present invention, the contact area is small and the sliding resistance is small compared to the floor joint cover device. Therefore, since the guided portion 27 slides on the guide portion 62 with a smaller force than the conventional floor joint cover device, the relative displacement of each of the housings 3a and 3b can be allowed smoothly. In addition, since the guided portion 27 can be easily constructed by welding the first supported member 21 and the end plate portion 24 and scraping the overlay, the telescopic guide device 1 is a second conventional type. The construction is simple compared to the technical floor expansion joint device, and the production cost can be reduced.

  According to the telescopic guide device 1 of the present embodiment, since the first supported member 21 and the second supported member 28 are movably supported by the sliding plate 52, the cover body 5 has a sliding plate than the conventional cover body. The contact area which contacts 52 is small. When the contact area is small, the sliding resistance can be reduced, and the relative displacement of each housing 3a, 3b is allowed smoothly. The second supported member 28 is guided upward by the sliding plate 52 when the second guided surface 29 comes into contact with the sliding plate 52 and the casings 3a and 3b are relatively displaced from each other, and the first supporting surface 73 is supported. Get on. As a result, the problem that the second supported member 28 and the sliding plate 52 are caught can be prevented, and the relative displacements of the respective housings 3a and 3b are smoothly allowed. Furthermore, the breakage of the second supported member 28 and the parting portion 66 based on the above-described problem can be prevented.

  Further, a gap is partially generated between the cover body 5 and the first support surface 73 by the other end portion 53 of the cover body 5 and the first and second supported members 21 and 28. Therefore, sand, dust and the like accumulated on the first support surface 73 can be discharged into the gap through the gap. As a result, sand or the like accumulated between the cover body and the casing is quickly discharged into the gap, and clogging caused by deposits such as sand and dust is suppressed. Accordingly, the cover body 5 can smoothly move on the first support surface 73, and the relative displacement of the first and second housings 3a and 3b can be allowed smoothly.

  According to the telescopic guide device 1 of the present embodiment, the cover body 5 has the cover body main body 10 formed in a lattice shape. Can lead to a drain. Accordingly, the cover body 5 can guide the liquid to the drainage groove that is the gap 4 while covering the gap 4, and can prevent a person and an object from fitting into the gap 4, thereby ensuring drainage. The cover body 5 is formed in the cover body main body 10 with the first and second supported members 21 and 28 being spaced apart from each other, and the plurality of sliding plates 52 are spaced apart from each other in the Y direction. As a result, the liquid guided to the cover body 5 can be prevented from accumulating on the first supported member 21, the second supported member 28, and the sliding plate 52, and the liquid can be drained into the drainage groove. Since the cover body 5 is grating, it is difficult to form the cover body body 10 by tilting the peripheral edge of the cover body body 10 upward as the cover body body 10 is separated from the cover body body 10. For this reason, an attachment piece 23 is provided at the end of the cover body 10 and the first auxiliary cover member 6 is attached to the cover body 5. With such a configuration, it is possible to easily realize the telescopic guide device 1 in which the other end portion of the cover body 5 can slide on the guide surface 64.

The third casing 68a includes a third floor 67a on which a protruding corner is formed and the locking means 2. A plurality of locking means 2 are provided on the peripheral edge of the protruding corner of the third floor 67a. Specifically, two locking means 2 are provided on two edge portions 92a and 92b respectively connected to the opposing wall surfaces.

  The fourth casing 68b includes a fourth floor 67b and support means 38A. On the fourth floor 67b, an opposing wall portion 54A, a horizontal portion 55A, and a rising portion 56A are formed. The opposing wall portion 54A, the horizontal portion 55A, and the rising portion 56A are formed in an L shape in plan view in the Z direction. The opposing wall portion 54A includes a first opposing wall portion 100 and a second opposing wall portion 101.

The sliding plate 52A supports each third supported member 32 so as to be able to move smoothly. Specifically, the sliding plate 52 </ b> A is disposed from the upper end of the portion where the first opposing wall portion 100 and the second opposing wall portion 101 are continuous to the lower end of the corner portion 76. The sliding plate 52A is formed in a symmetrical shape with respect to a line connecting the upper end and the lower end. The sliding plate 52A is composed of one member, for example, a single Teflon (registered trademark) processed rubber plate.

  When the cover body unit 69 is thus mounted between the two housings 68a and 68b, a gap can be formed at the portion where the first and second cover bodies 5a and 5b are abutted. Further, the auxiliary cover members 34 can be separated from each other by the second auxiliary cover members 7 that are abutted with each other.

  In the fourth casing 68b configured as described above, a first opposing wall surface 108 that is opposed to one opposing wall surface 109a of the third casing 68a is formed by the first opposing wall portion. A first support surface 73 extending leftward from the upper end of the first opposing wall surface 108 is formed by the second frame 51A and the sliding plates 52, 52A. A first guide surface 64 is formed by the first guide portion 104, and a second support surface 75 is formed by the first support portion 106.

A rising surface 65 rising upward from the second and third support surfaces 75 and 111 is formed by a part of the first and second standing portions 102 and 103.

  According to the telescopic guide device 1A of the present embodiment, the L-shaped gap 4 formed in the third floor 67a can be closed by the cover body unit 69. When the two casings 68a and 68b are relatively displaced, a force is applied to the cover bodies 5a and 5b in the direction in which the second auxiliary cover members 7 are close to each other, and the cover bodies 5a and 5b are relatively displaced in the direction. There is a case. At this time, since the third supported members 32 are separated by the second auxiliary cover member 7, the third supported members 32 are prevented from coming into contact with each other. As a result, it is possible to prevent damage to the cover bodies 5a and 5b and contact noise caused by contact between the cover bodies 5a and 5b. The problem that the cover bodies are brought into contact with each other and caught is prevented, and each third supported member 32 can smoothly move on the sliding plates 52 and 52A.

  According to the present invention, since a gap is formed between the second auxiliary cover members 7, it is possible to prevent the second auxiliary cover members 7 from coming into contact with each other even if the housings 68 a and 68 b are relatively displaced. it can. In addition, since the edge 33 of each second auxiliary cover member 7 is formed to be convex outward and curved in the vertical direction, each second auxiliary cover member 7 can be either upper or lower even if it abuts each other. Let one of them avoid each. As a result, even if the cover bodies 5a and 5b are mounted between the third and fourth casings 68a and 68b and the cover bodies 5a and 5b are relatively displaced in the direction of approaching each other, the second auxiliary cover members 7 are , And avoiding the problem of being caught by avoiding upward or downward respectively. Since the trouble which is caught can be prevented, relative displacement between each housing 68a, 68b can be permitted smoothly. Furthermore, the deformation and breakage of the second auxiliary cover member 7 based on the above-described problems are suppressed.

  Furthermore, since the second auxiliary cover members 7 are in contact with each other, the noise can be made smaller than the noise generated when the cover bodies 5 come into contact with each other as in the prior art. Furthermore, the second auxiliary cover member 7 closes the space formed by separating the third supported members 32, and can ensure safe and smooth passage on the cover bodies 5a and 5b.

  According to the telescopic guide device 1A of the present embodiment, when the housings 68a and 68b are relatively displaced in the Y direction, the first cover body 5a has the third supported member 32 extending along the second guide surface 112. It slides on the casing 68b. At this time, the guided portion 27 of the second cover body 5 b slides on the fourth casing 68 b along the second guide surface 112. Further, when the housings 68a and 68b are relatively displaced in the X direction, the guided portion 27 of the first cover body 5a slides on the fourth housing 68b along the first guide surface 64. At this time, in the second cover body 5 a, the third supported member 32 slides on the fourth casing 68 b along the first guide surface 64. Thus, since the first and second cover bodies 5a and 5b are relatively displaced, relative displacement in which the two-direction components in the X direction and the Y direction are combined can be smoothly allowed.

  According to the telescopic guide device 1A of the present embodiment, when the housings 68a and 68b are relatively displaced in the direction in which the two-direction components are combined in the X direction and the Y direction, the contact portions 77 of the cover bodies 5a and 5b are moved. In some cases, the corner portion 76 abuts. Even in this case, since the end surface of the contact portion 77 is formed to be curved outward and convex toward the tip, the end surface contacts the vicinity of the tip of the corner portion 76, and the tip However, it is possible to prevent the corner portion 76 from biting into the tip. Therefore, when the contact portion 77 is formed in a sharp shape, the first cover body 5a has its tip bitten into the tip of the corner portion 76, which causes a so-called wedge effect, but this embodiment prevents this. it can. Since the wedge effect can be prevented in this way, the first and second cover bodies 5a and 5b can be smoothly moved with respect to the other casing 68b. As a result, the relative displacement in which the two-direction components in the X direction and the Y direction of the respective casings 68a and 68b are combined can be allowed smoothly. Thus, it is possible to prevent the wedge effect from occurring and to prevent the contact portion 77 from being damaged. Further, since the contact surface 79 is curved upward, it is possible to prevent the wedge effect that the lower end of the contact portion 77 bites into the lower end portion of the corner portion 76.

  According to the telescopic guide device 1A of the present embodiment, since the third guided surface 78 is formed, the casings 68a and 68b are relatively displaced while the third guided surface 78 is in contact with the parting portion 66. Even so, the first and second cover bodies 5 a and 5 b are guided upward by the parting part 66. Thus, each third supported member 32 can avoid the parting portion 66. As a result, it is possible to prevent the third supported member 32 from being caught on the parting portion 66, and to allow the relative displacement of the respective casings 68a and 68b smoothly. Further, the third supported member 32 can be prevented from being damaged based on the above-mentioned problem.

  According to the telescopic guide device 1 </ b> A of the present embodiment, the top portion 35 of the auxiliary cover member 34 is formed to be curved outward and convex toward the tip, so that the fourth casing is similar to the contact portion 77. Biting into the tip of the corner 70 of the 68b can be prevented. Accordingly, even if the top portion 35 abuts the clear portion 662, the first and second cover bodies 5a and 5b can be smoothly moved, and the relative displacement of the third and fourth casing bodies 68a and 68b can be reduced. Smoothly acceptable.

  According to the telescopic guide device 1A of the present embodiment, the sliding plate 52A formed along the third supported member 32 allows the third supported member 32 to move smoothly. By configuring the sliding plate 52A with a single member, it is possible to eliminate the step formed when the sliding plate 52A is configured with a plurality of members. As a result, even if the respective casings 68a and 68b undergo relative displacement in which the two-direction components in the X direction and the Y direction are combined, the third supported member 32 moves smoothly on the sliding plate 52A without being caught by the sliding plate 52A. be able to. Thereby, the relative displacement of each housing can be allowed smoothly. Furthermore, the same effects as the telescopic guide device 1 of the first embodiment are obtained.
