Description

TECHNICAL FIELD The present invention relates to furniture with a rotating portion.

Tables disclosed in Patent Literatures 1 and 2 below are well known in fixtures with rotating parts in which main functional parts such as a top plate and a seat are supported so as to rotate with respect to a support structure that supports the relevant parts. is.
In these tables, the top plate, which is the main functional part, rotates from the use position, in which the wide surface is placed horizontally, to the non-use position, in which the same surface is upright, with respect to the legs as the support structure. is configured to By adopting such a configuration, a plurality of tables can be arranged side by side in the depth direction and organized.
In adopting such a configuration, in the rotating mechanism that rotatably connects the top plate to the legs, the angle of the top plate changes gradually. Apertures that shrink and expand with each other may occur.

Therefore, in the configuration disclosed in Patent Literature 1, the front cover 6 as a shielding member that is separate from the top plate support 32 is supported by the top plate support 32 at the upper portion of the non-use position. The front cover 6 has a free end portion at its lower end, and is inserted through an insertion hole 75 formed in an upper end portion of the support 23 that constitutes the leg and into the inner space of the support 23 . As a result, the opening that shrinks and expands as the top plate rotates can be shielded at all times.
Further, in the configuration disclosed in Patent Document 2, the point that the cover 34 separate from the top plate support 32 is supported by the top plate support 32 is the same. A portion 341 is pivotally supported, and this movable portion 341 functions as an extra length portion when the top plate is in the use position. As a result, the opening that gradually expands as the top plate switches from the use position to the non-use position can be effectively shielded.

Japanese Patent Application Laid-Open No. 2001-161446 JP 2014-079534 A

By the way, in order to always shield the opening that shrinks and expands, it is desirable to provide an accommodating portion that accommodates the shielding member in a detachable manner.
However, in the configurations disclosed in Patent Literatures 1 and 2, a hard shielding member is interposed between the top plate and the legs whose relative positions are gradually switched. Therefore, if the operation of the tabletop becomes disorderly or if there is a dimensional error between the tabletop and the legs, the smooth operation of the shielding member may be hindered. Moreover, it is likely to lead to breakage of the shielding member. In addition, there may be design restrictions such as the shape and size of the shielding member and the housing. Further, if the distal end portion of the movable portion 341 exposed to the outside is operated by hand, it easily returns to the state in which the opening is exposed.
The present invention has been made in view of the above technical problems, and ensures smooth operation of the shielding member that shields the opening of the rotating mechanism in a fixture with a rotating portion that is supported by a support structure. It is an object of the present invention to suppress breakage of the shielding member, improve the certainty of shielding, and increase the degree of design freedom.

As a means for solving the above problems, the present invention includes a rotating portion forming a wide surface and a support structure supporting the rotating portion, and a support structure between the supporting structure and the rotating portion. comprises a rotation mechanism that allows the rotation portion to rotate about a pivot that faces the surface, and the rotation mechanism includes a An opening that shrinks and expands is formed and includes a shielding member that shields the opening, the shielding member extends in a longitudinal direction crossing the axial direction of the pivot, and one longitudinal end side of the shielding member An accommodating portion is provided which is connected to one of the support structure and the rotating portion, and which detachably supports the other longitudinal end side of the shielding member in the other of the supporting structure and the rotating portion. and the rotating portion is rotatable between a first state in which the surface faces a first direction and a second state in which the surface faces a second direction intersecting with the first direction. and the shielding member secures an insertion margin with respect to the accommodating portion while the rotating portion rotates between the first state and the second state, and at least one of the shielding member and the accommodating portion is secured. provides a fixture with a rotating portion, comprising a deformation-permitting portion that elastically deforms as the rotating portion rotates, and enables the shielding member to be inserted into and removed from the accommodating portion.

According to this configuration, even if the opening of the rotating mechanism shrinks or expands as the rotating portion rotates around the pivot, the opening is shielded by the shielding member, so that articles or a body can be prevented from being caught in the opening. be done. Since the shielding member always secures an insertion allowance (overlap allowance) with respect to the accommodating portion while the rotating portion rotates between the first state and the second state, the opening of the rotation mechanism is always covered by the shielding member. As well as being shielded, the shielding member is prevented from falling out of the accommodating portion or being removed from the end portion exposed from the accommodating portion.
At least one of the shielding member and the accommodating portion is elastically deformed as the rotating portion rotates, allowing the shielding member to be inserted into and removed from the accommodating portion. Smooth operation of the shielding member is less likely to be hindered even if there is an error in the dimensional accuracy between them. Moreover, damage to the shielding member can be suppressed as compared with the case where both the accommodating portion and the shielding member are hard. Also, depending on the orientation and size of the storage portion, elastic deformation of the shielding member and the storage portion may not be necessary, but the designs such as the shape and size of the shielding member and the storage portion are likely to be restricted. On the other hand, since at least one of the shielding member and the accommodating portion is elastically deformed to enable insertion and removal of the shielding member, the design of the shielding member and the accommodating portion is less restricted.
As described above, according to the present invention, the smooth operation of the shield member that shields the opening between the support structure and the rotating portion is ensured, the breakage of the shield member is suppressed, the certainty of shielding is improved, and the design is improved. It is possible to provide fixtures with a rotating portion with a high degree of freedom.

In the present invention, the rotating portion is a top plate structure having a top plate, and the top plate structure has the first state in which the surface faces upward, and the first state in which the surface faces the first state. It may be configured to be rotatable between the second state of standing up and the second state.
In this case, it is possible to ensure the smooth operation of the shielding member that shields the opening between the support structure and the top structure, suppress the damage of the shielding member, and provide a fixture with a top with a high degree of freedom in design. .

In the present invention, the deformation permitting portion may be provided in a range extending from one longitudinal end side to the other longitudinal end side of the shielding member.
In this case, since the shielding member is elastically deformed over a wide range from one end side to the other end side, the overall elastic deformation of the shielding member makes the shielding member smoother than the configuration in which the shielding member is elastically deformed locally. It is possible to ensure a smooth operation and to suppress the local load on the shielding member to improve durability. The range extending from one end side to the other end side in the longitudinal direction of the shielding member is a range having a width extending to both end sides including the central portion in the longitudinal direction of the shielding member.

In the present invention, the accommodating portion is supported by the rotating portion, and includes a cover member that faces the first wide surface in the first direction when the rotating portion is in the first state, and the shielding The member is supported by the support structure, and when the rotating portion is in the first state, the second wide surface faces the first direction, and at least a part of the second wide surface faces the A configuration may be adopted in which an elastic plate member as the deformation-allowing portion is arranged so as to overlap the first wide surface of the cover member.
In this case, when the rotating portion is in the first state, the elastic plate member of the shielding member is arranged along the first wide surface substantially parallel to the surface of the rotating portion of the cover member of the housing portion. Therefore, the shielding member can be accommodated in the accommodating portion and can be inserted and removed in a compact manner without being bulky. In addition, the end portion of the elastic plate member, which is to be accommodated in the accommodation portion, is less likely to be exposed to the outside. can.

In the present invention, the cover member has a back wall facing the tip end portion of the elastic plate member on the side accommodated in the accommodation portion, and the elastic plate member is in the first state at the rotating portion. WHEREIN: The insertion length to the said accommodating part may become the maximum, and the structure may be elastically deformed by abutting the said front-end|tip part on the said inner wall.
In this case, when the length of insertion of the elastic plate member into the housing portion is maximized, the tip of the elastic plate member abuts against the back wall of the cover member and is elastically deformed. Also, the elastic plate member can be accommodated in the accommodation portion by avoiding an increase in size of the accommodation portion in the depth direction. Therefore, it is possible to prevent damage to the shielding member and increase the degree of freedom in designing the shielding member and the accommodating portion, while securing a sufficient length of the elastic plate member to reliably shield the opening.

In the present invention, the shielding wall may shield the shielding member from the width direction intersecting the longitudinal direction.
In this case, since a shielding wall that shields the shielding member from the side is provided, the end of the shielding member in the width direction is less likely to be exposed, and the shielding member may be removed from the accommodating portion due to the disturbance catching on the end of the shielding member. can be deterred.

According to the present invention, in a fixture with a rotating portion in which the rotating portion is supported by the support structure, the smooth operation of the shielding member that shields the opening of the rotating mechanism is ensured, the damage of the shielding member is suppressed, and the shielding is prevented. It is possible to increase certainty and increase the degree of design freedom.

As shown in FIG. Both ends of the pivot 2 pass through the pair of side walls 13b of the first metal fitting 13 to the outside thereof. A first hook 25 for locking a first locking pin 31, which will be described later, is formed at a portion of the pair of side walls 23b on the front side in the furniture depth direction relative to the support 22. As shown in FIG. A second hook 26 for locking a second locking pin 32, which will be described later, is formed at a portion of the pair of side walls 23b on the back side of the support 22 in the furniture depth direction and below the pivot 2. As shown in FIG.

In the first state A of the top plate structure 10, the lower surface of the upper wall 13a of the first metal fitting 13 contacts the upper surface of the upper wall 23a of the fixing metal fitting 23, and the load from the top plate structure 10 is input. . The fixing metal fitting 23 constitutes a top plate supporting portion of the support structure 20 and supports the supported portion (the first metal fitting 13 ) of the top plate structure 10 so as to be rotatable around the pivot 2 . A rotating mechanism 15 including a fixing metal fitting 23 , a first metal fitting 13 and a pivot shaft 2 is configured between the top plate structure 10 and the support structure 20 .

<Top plate lock mechanism 30>
6 to 8, the table 1 includes a top board lock mechanism 30 that locks the rotation of the top board structure 10 around the pivot 2 in each of the first state A and the second state B. As shown in FIG.
The top plate lock mechanism 30 is supported by the first hook 25 and the second hook 26 formed on the pair of side walls 23b of the fixing bracket 23 and the inside of the first bracket 13 so as to be slidable in the fixture depth direction by a specified amount. and the first locking pin 31 and the second locking pin 32 extending in the fixture width direction over a pair of side walls 33a on both sides in the fixture width direction of the slide fixture 33 . The first locking pin 31 penetrates the pair of side walls 13b of the first metal fitting 13 to the outside thereof.

The first hook 25 has a U-shape that opens toward the front in the depth direction of the furniture when viewed from the side, and forms a substantially horizontal first locking side 25a on the top. A first locking pin 31 is locked to the first locking side 25a from below. Due to this locking, upward movement of the furniture depth direction front side of the top plate structure 10 in the first state A is restricted. That is, the top plate structure 10 in the first state A is restricted from rotating to the second state B, and the top plate structure 10 is held in the first state A.

The second hook 26 has a U shape that opens upward when viewed from the side, and forms a substantially vertical second locking side 26a on the far side in the furniture depth direction. When the top plate structure 10 is in the second state B, the second locking pin 32 is locked to the second locking side 26a from the far side in the furniture depth direction. Due to this locking, the back side (lower side) of the top plate structure 10 in the second state B is restricted from moving to the back side in the furniture depth direction. That is, the rotation of the top structure 10 in the second state B to the first state A is restricted, and the top structure 10 is held in the second state B.

A pair of side walls 33a of the slide fitting 33 are formed with long holes 33b elongated in the furniture depth direction at positions overlapping the pivot shaft 2 in a side view. Both ends of the pivot 2 are inserted into the long holes 33b so as to be slidable in the fixture depth direction. The pair of side walls 13b of the first metal fitting 13 are formed with long holes 13c elongated in the fixture depth direction at positions overlapping the first locking pins 31 in a side view. Both ends of the first locking pin 31 are inserted into the long hole 13c so as to be slidable in the fixture depth direction. Large-diameter washers 13c1 are attached to both ends of the first locking pin 31 to prevent exposure of the long hole 13c.

A strip-shaped operation piece 34 extending toward the front side in the depth direction of the fixture along the lower surface of the upper wall 13a of the first metal fitting 13 is connected to the slide metal fitting 33 at the front end in the depth direction of the fixture. A handle 34a is provided at the end of the operation piece 34 on the front side in the furniture depth direction so as to protrude downward so that the user can put his or her finger on the handle 34a.

The operating piece 34 is formed with a long hole 34b elongated in the furniture depth direction, for example, in the middle part in the longitudinal direction. A shaft portion of a support bolt B2 is inserted through the elongated hole 34b so as to be slidable in the depth direction of the furniture. The slide fitting 33 is slidably supported in the fixture depth direction with respect to the first fitting 13 by a sliding amount defined by the lengths of the long holes 33b and 34b.

A handle 34a on the front side in the furniture depth direction of the operation piece 34 is provided so as to overlap the end portion of the first metal fitting 13 on the front side in the furniture depth direction in a side view. One end of a tension coil spring 35 is engaged with the end of the slide fitting 33 on the far side in the furniture depth direction. The other end of the tension coil spring 35 is locked by a locking piece 36 hanging down from the upper wall 13 a of the first metal fitting 13 on the far side of the furniture depth direction from the slide metal fitting 33 . In the figure, reference numeral 37 denotes a back side cover member that is attached to the back side of the fixture depth direction of the first metal fitting 13 and shields the tension coil spring 35 and the locking piece 36; fasteners for securing to the side wall 13b of the .

The slide fitting 33 is biased by the biasing force of the tension coil spring 35 toward the stroke end on the far side in the depth direction of the furniture within the stroke range defined by the long holes 33b and 34b. When the handle 34a is pulled forward in the fixture depth direction against the biasing force of the tension coil spring 35, the slide fitting 33 slides toward the stroke end on the fixture depth direction front side within the stroke range.

When the slide fitting 33 moves to the stroke end on the front side in the furniture depth direction, the first locking pin 31 retreats from the locking position with the first hook 25, and the top plate structure 10 rotates in the first state A. unlocked. Thereby, the top plate structure 10 can be rotated from the first state A to the second state B. As shown in FIG.

On the other hand, in the second state B of the top plate structure 10, when the handle 34a is pulled toward the front side in the depth direction of the top plate and the slide fitting 33 moves to the stroke end on the front side in the depth direction of the top plate, the second locking pin 32 retracts from the locking position with the second hook 26, and the rotation lock in the second state B of the top plate structure 10 is released. Thereby, the top plate structure 10 can be rotated from the second state B to the first state A. As shown in FIG.

<Shielding member 40>
With reference to FIGS. 6 to 8, between the fixing metal fitting 23 and the first metal fitting 13, the fixing metal fitting 23 and the first metal fitting 13 approach each other as the top plate structure 10 rotates about the pivot shaft 2. An opening K1 that shrinks and expands in the direction of rotation about the pivot 2 is formed by moving apart. The opening K1 expands when the top plate structure 10 rotates from the first state A to the second state B, and contracts when the top plate structure 10 rotates from the second state B to the first state A. do. The table 1 includes a shielding member 40 that shields the opening K1 in order to prevent the body or objects from entering the opening K1.

The shielding member 40 includes a rotating metal fitting 41 rotatably connected to the fixture depth direction front side of the fixing metal fitting 23, and a band plate to which one longitudinal end portion (base end portion 42a) is coupled to the rotating metal fitting 41. and an elastic plate member 42 having a shape. The elastic plate member 42 has a length corresponding to a change in the size of the opening K1 that shrinks and expands as the top plate structure 10 rotates, and is made of an elastic resin plate such as soft polypropylene. there is The elastic plate member 42 has a width direction parallel to the axial directions of the pivot 2 and the second pivot 43, a longitudinal direction perpendicular to the width direction, and a thickness direction perpendicular to the width direction and the longitudinal direction. ing. The elastic plate member 42 extends in the longitudinal direction with a constant band width.

The elastic plate member 42 has an initial shape extending in a generally linear shape (specifically, a shallow V shape) in a side view in the width direction (reference numeral 42' in FIGS. 7 and 8). indicated by a chain line), and can be bent by appropriately elastically deforming from this initial shape. The elastic plate member 42 is elastically deformed by slidably contacting an accommodation portion 50 described later as the top plate structure 10 rotates, so that it can be inserted into and removed from the accommodation portion 50 as the top plate structure 10 rotates. becomes. In other words, the elastic plate member 42 constitutes a deformation-permitting portion that is elastically deformed as the top plate structure 10 rotates to enable insertion into and removal from the accommodating portion 50 . The shielding member 40 is not provided with a deformation-permitting portion (elastic plate member 42) locally, but is provided over a wide range (including the central portion in the longitudinal direction) from one end side to the other end side in the longitudinal direction. It facilitates elastic deformation and suppresses local loads due to elastic deformation. A protrusion 42d (see FIG. 8) that protrudes downward in the first state A is provided at one end (tip 42b) of the elastic plate member 42 in the longitudinal direction. In the second state B, the convex portion 42d is elastically engaged with a concave portion 52d (see FIG. 8) formed on the upward surface of the guide member 52 in the first state A, which will be described later. As a result, the distal end portion 42b of the elastic plate member 42 is prevented from falling out of the housing portion 50 in the second state B. As shown in FIG.

The rotating metal fitting 41 is located on the side of the pair of side walls 23b of the fixing metal fitting 23 on the nearer side in the fixture depth direction than the support 22 and below the first hook 25 via a second pivot 43 parallel to the pivot 2. It is rotatably connected. The rotating metal fitting 41 and thus the shielding member 40 are connected to the fixing metal fitting 23 at a position opposite to the pivot 2 across the support 22 in the furniture depth direction (position away from the pivot 2).

The rotating metal fitting 41 has a U-shape opening upward, and is formed, for example, by bending a sheet metal. The rotating metal fitting 41 has a rectangular shielding wall 41a in plan view parallel to the second pivot 43, and a pair of side walls 41b bending upward and extending from both sides of the shielding wall 41a in the furniture width direction. Both ends of a second pivot shaft 43 extending between the pair of side walls 23b of the fixing bracket 23 are inserted and supported by the parts of the pair of side walls 41b on the far side in the furniture depth direction. The shielding wall 41a has a shallow bent shape that protrudes downward when viewed from the side in the width direction of the furniture. The shielding wall 41a has an inclined wall 41a1, which is located on the front side of the fixture in the depth direction of the bent portion formed substantially at the center in the depth direction of the fixture and is inclined upward toward the front of the fixture in the depth direction.

A base end portion 42a of the elastic plate member 42 is fixed to the upper surface of the inclined wall 41a1 by a pair of fasteners B3. That is, one end portion (base end portion 42 a ) of the elastic plate member 42 in the longitudinal direction is connected to the fixing metal fitting 23 and thus the support structure 20 via the rotating metal fitting 41 . The other end side (front end side) of the elastic plate member 42 in the longitudinal direction is inserted into and supported by a housing portion 50 provided in the top plate structure 10 so as to be removable in the longitudinal direction.

The shielding member 40 extends from the connection end 45 to the support structure 20 (base end near the second pivot 43 of the fixture 23) to the opposite end in the longitudinal direction (tip 42b of the elastic plate member 42). is longer than the maximum value of the length from the connecting end portion 45 to the opening K2 of the accommodating portion 50 (the length in the second state B). Therefore, the elastic plate member 42 always secures an insertion allowance for the accommodating portion 50 while the top plate structure 10 rotates between the first state A and the second state B. As shown in FIG. That is, the front end side of the elastic plate member 42 in the longitudinal direction is always inserted into and supported by the housing portion 50 of the top plate structure 10 .

The elastic plate member 42 is inserted into and removed from the housing portion 50 while being in sliding contact with the periphery of the opening K2 of the housing portion 50 and the inner wall surface thereof. When the top plate structure 10 rotates from the first state A to the second state B, the shielding member 40 rotates the rotating metal fitting 41 around the second pivot 43 so as to follow the rotation of the top plate structure 10. upwards. As a result, the shielding member 40 is oriented such that its longitudinal direction is along the depth direction of the housing portion 50 . Before the top plate structure 10 reaches the second state B, the rotating metal fitting 41 abuts on the first hook 25 and is restricted from rotating upward. After that, when the top plate structure 10 further rotates, the elastic plate member 42 is elastically deformed so as to bend in an S shape in a side view in the width direction (bend in the thickness direction), and the accommodation portion 50 is inserted/removed with respect to

In the first state A of the top plate structure 10 , the elastic plate member 42 has the maximum length of insertion into the housing portion 50 . In the first state A of the top plate structure 10 , the elastic plate member 42 abuts the end portion 42 b against the inner wall 51 b of the housing portion 50 , so that the elastic plate member 42 is elastically deformed so as to warp as a whole in a side view. In the figure, reference numeral 52 is a guide member that is fixed inside the housing portion 50 and regulates the position of the elastic plate member 42 when it is elastically deformed. fasteners, are shown. The guide member 52 also serves as a leg portion for fixing the cover member 51 (to be described later) to the first metal fitting 13 .

6 to 8, the housing portion 50 includes a first metal fitting 13 and a cover member 51 attached inside the first metal fitting 13. As shown in FIG.
The cover member 51 is arranged between the pair of side walls 13b of the first metal fitting 13, and is fastened (fastened) together with the first metal fitting 13 to the back surface 11b side of the top plate 11. As shown in FIG. The cover member 51 is formed, for example, by bending sheet metal.

The cover member 51 includes a band plate-like cover wall 51a extending obliquely so that the front side of the furniture in the depth direction is positioned on the top plate 11 side, and an upper end of the cover wall 51a on the front side of the furniture in the depth direction (the top plate 11 side) and a back wall 51b that is bent to stand up. The cover wall 51a forms a first wide surface 51c facing in the vertical direction. The inner wall 51b faces the distal end portion 42b of the elastic plate member 42 accommodated in the accommodation portion 50 in the furniture depth direction. The cover member 51 extends in the depth direction of the furniture along the back surface 11b of the top plate 11 together with the first metal fitting 13 having a U-shaped cross section that opens downward, and forms a storage part 50 that is closed on the near side in the depth direction of the furniture. ing. The longitudinal direction (depth direction) of the housing portion 50 faces the fixture depth direction. A pair of side walls 13b of the first metal fitting 13 constitute a shielding wall 13b1 rising downward from the back surface 11b side of the top plate 11 so as to shield the shielding member 40 from the fixture width direction.

The elastic plate member 42 forms a second wide surface 42c facing in the vertical direction. When the elastic plate member 42 is housed in the housing portion 50 , at least a portion of the second wide surface 42 c (the other end in the longitudinal direction) overlaps the first wide surface 51 c of the cover member 51 . The overlapping margin of the wide surfaces 42 c and 51 c in the longitudinal direction of the shielding member 40 corresponds to the insertion margin of the shielding member 40 into the accommodating portion 50 .

The accommodation portion 50 is at a height overlapping the pivot 2 in the vertical direction. The housing portion 50 is arranged on the near side in the depth direction of the fixture with respect to the pivot shaft 2 in the top plate structure 10 . When the top plate structure 10 rotates, the accommodating portion 50 does not approach or separate from the pivot 2 which is the center of rotation, but approaches or separates from the pivot 2 at a distance. Since the connecting end portion 45 of the shielding member 40 to the support structure 20 is separated from the pivot 2, the accommodating portion 50 approaches and separates from the connecting end portion 45 when the top plate structure 10 rotates. do.

The opening K2 of the housing portion 50 faces the opening K1 of the rotating mechanism 15, and the shielding member 40 (elastic plate member 42) is inserted into and removed from the housing portion 50 through the opening K2. At this time, the elastic plate member 42 is inserted into and removed from the accommodation portion 50 while being elastically deformed when viewed in the width direction by slidably contacting the periphery of the opening K2 and the inner wall surface of the accommodation portion 50 . The shielding member 40 is inserted into and removed from the accommodating portion 50, thereby absorbing changes in the distance between the connecting end portion 45 and the accommodating portion 50 when the top plate structure 10 is rotated. The opening K1 is kept closed.

If the accommodating part 50 is arranged so that the depth direction is along the longitudinal direction of the shielding member 40 or if the opening K2 side is widened, there is a possibility that the shielding member 40 can be inserted and removed without being elastically deformed. , the orientation and size of the accommodating portion 50 are restricted.

The storage unit 50 of this embodiment has a vertical dimension (thickness direction of the top plate 11) smaller than each dimension in the depth direction and the width direction of the fixture, and is flat with a reduced overall vertical dimension. shape. By forming such a flat housing portion 50, projection of the housing portion 50 to the back surface 11b side of the top plate 11 is suppressed, and the back surface 11b side of the top plate 11 is made compact (particularly, the top plate structure 10 is the first It contributes to compactness when it becomes two states B).

The shielding member 40 rotates around the second pivot 43 so as to follow the rotation of the top plate structure 10 . When the top structure 10 rotates from the first state A toward the second state B, the shielding member 40 is provided until the rotation of the rotating metal fitting 41 is restricted by contact with the fixing metal fitting 23. are arranged such that the longitudinal direction thereof extends along the depth direction of the accommodating portion 50 . Therefore, the elastic plate member 42 is inserted into and removed from the accommodating portion 50 without being elastically deformed.

When the top plate structure 10 further rotates toward the second state B after the rotation of the rotating metal fitting 41 is restricted, the longitudinal direction of the shielding member 40 and the depth direction of the housing portion 50 begin to deviate. Therefore, the elastic plate member 42 is pushed by the cover member 51 in the thickness direction and is elastically deformed into an S shape when viewed from the side, and is inserted into and removed from the accommodating portion 50 . In this manner, the elastic plate member 42 is appropriately bent to be inserted into and removed from the accommodating portion 50, thereby suppressing breakage and malfunction of the shielding member 40. FIG.

<Action>
Next, the action will be described.
First, when the top plate structure 10 is in the first state A, the elastic plate member 42 of the shielding member 40 abuts the end portion 42b against the inner wall 51b of the housing portion 50 so that the entirety is warped in a side view. elastically deformed. This makes it possible to reduce the dimension of the housing portion 50 in the depth direction while ensuring the length of the elastic plate member 42 . In addition, even if the insertion/removal stroke of the elastic plate member 42 into and out of the accommodation portion 50 increases, the lapping allowance between the elastic plate member 42 and the accommodation portion 50 is ensured, thereby preventing the shielding member 40 from falling out of the accommodation portion 50. be done. In addition, by securing the length of the elastic plate member 42, the elastic deformation of the elastic plate member 42 is facilitated. Even if it becomes rough or a dimensional error occurs between the top structure 10 and the support structure 20, the local load on the shielding member 40 and the housing portion 50 is suppressed. Therefore, damage to the shielding member 40 and the housing portion 50 is suppressed, and the rotation of the top plate structure 10 immediately before reaching the first state A becomes smooth.

When the top plate structure 10 is in the first state A, the shielding member 40 rotates so that the rotating metal fitting 41 is substantially horizontal, and the longitudinal direction is the depth direction of the housing portion 50 (furniture in the first state A). (which is also the depth direction). At this time, the rotating end portion of the rotating metal fitting 41 on the front side in the furniture depth direction is close to the open end portion of the cover member 51 on the back side in the furniture width direction. The elastic plate member 42 abuts the open end portion of the cover member 51 on the far side in the width direction of the fixture from above, thereby restricting the downward rotation of the rotating metal fitting 41 . When the top plate structure 10 is in the first state A, the upper surface of the upper wall 23a of the fixing bracket 23 and the lower surface of the upper wall 13a of the first bracket 13 are in contact with each other, thereby closing the opening K1 of the rotating mechanism 15. do.

When the top plate structure 10 is in the first state A, the rotation of the top plate structure 10 is locked by the top plate lock mechanism 30 . From this state, when the slide fitting 33 is pulled forward in the furniture depth direction, the first locking pin 31 retreats from the locking position with the first hook 25, and the top plate structure 10 in the first state A The rotation lock is released. Thereby, the top plate structure 10 can be rotated from the first state A to the second state B. As shown in FIG.

When the top plate structure 10 is rotated from the first state A to the second state B, the shield member 40 is rotated upward around the second pivot 43 by lifting the elastic plate member 42 by the cover member 51. and change the longitudinal direction upward. When the top plate structure 10 is rotated from the first state A to the second state B, the opening K1 of the rotation mechanism 15 opens and expands. 40, and is shielded from both sides in the furniture width direction by a pair of side walls 13b (shielding walls 13b1) of the first metal fitting 13. As shown in FIG. For this reason, the opening K1 is not exposed to the outside, and articles and the body are prevented from entering the opening K1.

As the upright angle of the top plate structure 10 increases, the accommodating portion 50 is gradually separated from the connecting end portion 45 of the shielding member 40 . Even if the accommodating portion 50 is separated from the connecting end portion 45 of the shielding member 40, the elastic plate member 42 is pulled out from the accommodating portion 50, so that the shielding member 40 shields the opening K1.

The top plate structure 10 further rotates even after the rotating metal fitting 41 abuts against the fixing metal fitting 23 and the rotation is restricted. At this time, the front end side of the elastic plate member 42 in the longitudinal direction is pushed by the cover member 51 toward the depth direction of the fixture, so that the front end side of the elastic plate member 42 in the longitudinal direction is pushed toward the depth direction of the fixture with respect to the base end side. elastically deformed so as to displace Since the elastic plate member 42 has a sufficient length, it is easily elastically deformed, and the rotation just before the top plate structure 10 reaches the second state B is smooth. Further, by providing the elastic plate member 42 with a long length, the local load on the shielding member 40 and the housing portion 50 is suppressed, and damage to these members is also suppressed.

As described above, the fixture with a rotating portion of the present embodiment includes the top plate structure 10 having the top plate 11 forming the wide surface 11a, and the support structure 20 supporting the top plate structure 10. , between the support structure 20 and the top plate structure 10, a rotation mechanism that allows the top plate structure 10 to rotate about two pivots that face the direction along the surface 11a. The rotating mechanism 15 is formed with an opening K1 that shrinks and expands as the top plate structure 10 rotates about the pivot 2, and a shielding member 40 that shields the opening K1 is provided. The shielding member 40 extends in a longitudinal direction intersecting the axial direction of the pivot 2, and one end side (base end side) of the shielding member 40 in the longitudinal direction is connected to the support structure 20 and connected to the ceiling. The plate structure 10 is provided with a housing portion 50 that detachably supports the other end side (front end side) of the shielding member 40 in the longitudinal direction. Between the first state A facing the direction (upward) and the second state B standing facing the second direction (furniture depth direction back side) intersecting the first direction with the surface 11a The shielding member 40 is rotatable, and secures an insertion allowance for the accommodating portion 50 while the top plate structure 10 rotates between the first state A and the second state B, The shielding member 40 includes a deformation permitting portion (elastic plate member 42) that elastically deforms as the top plate structure 10 rotates and allows the shielding member 40 to be inserted into and removed from the accommodating portion 50. .

According to this configuration, even if the opening K1 of the rotating mechanism 15 shrinks or expands as the top plate structure 10 rotates about the pivot 2, the opening K1 is shielded by the shielding member 40. It is possible to prevent objects or bodies from being caught. Since the shielding member 40 always secures an insertion allowance (overlap allowance) with respect to the housing portion 50 while the top plate structure 10 rotates between the first state A and the second state B, the rotation mechanism 15 The opening K1 of is always blocked by the shielding member 40, and the shielding member 40 is prevented from dropping out of the accommodating portion 50 or being removed from the end portion exposed from the accommodating portion 50.例文帳に追加
The shielding member 40 is elastically deformed as the top plate structure 10 rotates, allowing the shielding member 40 to be inserted into and removed from the accommodating portion 50. This makes the operation of the top plate structure 10 messy and difficult. Smooth operation of the shielding member 40 is less likely to be hindered even if there is an error in the dimensional accuracy between the members. In addition, damage to the shielding member 40 is suppressed as compared with the case where both the accommodating portion 50 and the shielding member 40 are hard. Moreover, although elastic deformation of the shielding member 40 may be unnecessary depending on the direction and size of the storage portion, the design such as the shape and size of the shielding member 40 and the storage portion 50 is likely to be restricted. On the other hand, since the shielding member 40 is elastically deformed so that the shielding member 40 can be inserted and removed, the design of the shielding member 40 and the housing portion 50 is less restricted.
As described above, according to the present embodiment, the smooth operation of the shielding member 40 that shields the opening K1 between the support structure 20 and the top structure 10 is ensured, the damage of the shielding member 40 is suppressed, and the shielding is prevented. It is possible to provide a fixture with a rotating portion (furniture with a top plate) that enhances certainty and has a high degree of freedom in design.

In addition, in the fixture with a rotating portion of the present embodiment, the deformation permitting portion is provided in a range extending from one end side to the other end side in the longitudinal direction of the shielding member 40 .
According to this configuration, the shielding member 40 is elastically deformed over a wide range from one end side to the other end side. , the smoother operation of the shielding member 40 can be ensured, and the local load on the shielding member 40 can be suppressed to improve durability.

In addition, in the furniture with a rotating portion of the present embodiment, the accommodation portion 50 is supported by the top plate structure 10, and when the top plate structure 10 is in the first state A, the first wide surface 51c facing the first direction, the shielding member 40 is supported by the support structure 20, and when the top plate structure 10 is in the first state A, the second wide width An elastic plate member serving as the deformation-allowing portion, in which the surface 42c is directed in the first direction and at least a part of the second wide surface 42c is arranged so as to overlap the first wide surface 51c of the cover member 51. 42.
According to this configuration, when the top plate structure 10 is in the first state A, the elastic plate member 42 of the shielding member 40 is approximately the surface 11 a of the top plate structure 10 in the cover member 51 of the housing portion 50 . Since the shielding member 40 is arranged along the parallel first wide surface 51c, the shielding member 40 can be compactly housed in the housing portion 50 and can be inserted/removed. In addition, the elastic plate member 42 does not easily expose the end portion 42b of the elastic plate member 42 on the side accommodated in the accommodation portion 50 to the outside, and the elastic plate member 42 may be removed from the accommodation portion 50 by being caught by disturbance at this end portion. can be deterred.

In addition, in the fixture with a rotating portion of the present embodiment, the cover member 51 includes a back wall 51b facing the tip portion 42b of the elastic plate member 42 on the side accommodated in the accommodation portion 50, and the elastic plate When the top plate structure 10 is in the first state A, the member 42 has the maximum length of insertion into the accommodating portion 50 and is elastically deformed by abutting the distal end portion 42b against the inner wall 51b. do.
According to this configuration, when the insertion length of the elastic plate member 42 into the accommodating portion 50 is maximized, the distal end portion 42b of the elastic plate member 42 collides with the inner wall 51b of the cover member 51 and is elastically deformed. Even if the plate member 42 is provided in a long length, the size of the accommodating portion 50 in the depth direction is avoided, and the elastic plate member 42 can be accommodated in the accommodating portion 50 due to the elastic contact of the elastic plate member 42 . Therefore, the length of the elastic plate member 42 is sufficiently secured so that the opening K1 can be reliably shielded, damage to the shielding member 40 is suppressed, and the degree of freedom in designing the shielding member 40 and the accommodating portion 50 can be increased. can.

In addition, the fixture with a rotating portion of the present embodiment includes a shielding wall 13b1 that shields the shielding member 40 from the width direction intersecting the longitudinal direction.
According to this configuration, since the shielding wall 13b1 that shields the shielding member 40 from the side is provided, the end of the shielding member 40 in the width direction is less likely to be exposed, and the shielding member 40 is accommodated by being caught by the disturbance on this end. Removal from the unit 50 can be prevented.
