Description

  The present invention relates to a furniture with a top plate that is configured to be movable between a use position and a storage position and that has a biasing mechanism that biases the top plate toward the storage position.

Conventionally, various types of furniture with a top plate have been conceived in which the top plate can be moved between a use position and a storage position. In such furniture with a top plate, when the top plate is suddenly moved from the storage position to the use position, there is a problem that a finger is caught in a gap between the top plate elements. In order to solve this problem, various modes have been considered in which a biasing mechanism for biasing the top plate toward the storage position and a mode in which a damper is provided between the top plate and the leg (for example, (See Patent Documents 1 and 2).
Japanese Utility Model Publication No. 40-20687 JP 2001-137049 A

  Incidentally, in the configuration described in Patent Document 1, the coil spring is exposed even when the top plate is arranged at the storage position. With such a configuration, when the furniture with the top plate is stored, the coil spring is damaged due to an impact from the outside, or a foreign object is caught in the movement path of the coil spring and the top plate cannot be moved to the use position. Can occur. Moreover, in the structure of patent document 2, since a damper is required, a mechanism becomes complicated compared with the aspect using a coil spring.

  The present invention is configured to solve the problems described above.

That is, the furniture with a top plate according to the present invention is provided with a leg, a top plate supported by the leg and rotatable between a use position and a storage position, and the top plate facing the storage position. And a biasing mechanism having a coil spring with a fixed end side supported by the leg body and a free end side supported by the top plate, and the top plate being retracted. The coil spring is stored in a space defined by a recess provided on the leg and the top plate when moved to the bottom, and the free end side of the coil spring is placed on the lower surface of the top plate. A supportable free end bracket is provided, and the width of the free end bracket is smaller than the width of the recess .

If it is such, a coil spring will be accommodated in the space defined by the said recessed part and a top plate in an accommodation position. That is, the coil spring is concealed from the external space by the leg and the top plate. Therefore, it is possible to suppress the occurrence of a problem that the coil spring is damaged by receiving an impact from the outside when the table is stored, or a problem that the top plate cannot be moved due to a foreign object caught in the movement path of the coil spring. Further, a free end bracket capable of supporting the free end side of the coil spring is provided on the lower surface of the top plate, and the width dimension of the free end bracket is smaller than the width dimension of the concave portion. The whole can be stored in the recess of the leg body without difficulty, and can be arranged in a space defined by the recess and the top plate.

  Further, as a preferred aspect when the coil spring is covered with a cover, a fixed end member for supporting the fixed end side of the coil spring is provided on the leg body, and the fixed end of the coil spring is provided on the fixed end member. And a positioning groove that can be engaged with the side. With such a configuration, the fixed end side of the coil spring can be positioned in the depth direction of the leg, so that the cover covering the coil spring is twisted when the fixed end side of the coil spring moves in the depth direction of the leg. It is possible to prevent the occurrence of defects that are damaged by the force of the direction.

  In particular, if the free end bracket is provided with a pair of legs that are spaced apart in the depth direction of the leg body and has a hanging portion that restricts the movement of the free end of the coil spring, the table is stored. The free end side of the coil spring can be prevented from shaking in the depth direction of the leg, and the coil spring can be securely stored in a space defined by the recess and the top plate provided in the leg. In addition, with such a configuration, when a cover that covers the coil spring is provided, it is possible to suppress the occurrence of a problem that the cover is caught between the leg and the top plate when the table is stored.

  In addition, as a configuration for facilitating the movement from the storage position to the use position to some extent, only when the top plate is on the use position side from a predetermined position between the use position and the storage position. The thing by which the free end side of the said coil spring is supported by a top plate is mentioned. In such a case, when the top plate is moved from the storage position to the predetermined position, the top plate does not receive a biasing force toward the storage position side from the biasing mechanism, and therefore the top plate is moved in this region. This is because there is no need to resist the biasing force.

  In particular, a free end bracket capable of supporting the free end side of the coil spring is provided on the lower surface of the top plate, and the free end bracket is located at a position where the free end side of the coil spring is separated from the lower surface of the top plate. As long as the top plate is moved from the predetermined position to the storage position, it is possible to secure room for the free end of the coil spring to move away from the top plate.

  Further, as an aspect in which the effect of the present invention can be suitably obtained, the top plate has a top plate element provided in a pair of left and right, and the left and right top plate elements have a use position and a storage position, respectively. The thing which can be rotated between is mentioned.

  In particular, if a link mechanism is provided between the left and right top plate elements to move the left and right top plate elements in synchronization, the action applied to one of the top plate elements via the link mechanism is Since it can be transmitted to the other top plate element, the top plate can be moved from the use position to the storage position or vice versa by acting only on one top plate element.

  According to the configuration of the furniture with a top plate according to the present invention, the coil spring of the biasing mechanism is stored in the space defined by the recess of the leg body and the top plate at the storage position, and therefore the biasing mechanism is the leg body. And because it is concealed from the external space by the top plate, the coil spring is damaged by receiving external shocks when storing the furniture with the top plate, and the top plate is moved to the use position due to foreign matter caught in the movement path of the coil spring. It is possible to suppress the occurrence of problems that cannot be performed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the table T which is a furniture with a top plate according to the present embodiment is used for a pair of left and right legs 1, 1 provided upright from the floor, and the leg 1.

The coil spring 31 is supported by supporting the end side (free end 313). In this embodiment, when the top plate 2 is moved to the storage position S, the coil spring 31 is placed in a space defined by the recess 1x provided on the leg column 12 of the leg 1 and the top plate 2. I try to store it. 4 is a perspective view of the biasing mechanism 3 from the free end 313 side, FIG. 5 is an enlarged perspective view of the vicinity of the fixed end 312 of the biasing mechanism, and FIG. FIG. 3 shows a front sectional view of the vicinity of the urging mechanism 3 in a state where the top plate 2 is disposed at the use position U.

  More specifically, the coil spring 31 is a fixed end that is supported by a coil spring main body 311 having a function as a coil spring and a spring support member 121 provided on one end of the coil spring main body 311 and provided on the leg support 12. A free end 313 that can be engaged with a spring support bracket 24 provided at the other end of the coil spring body 311 and provided at the top plate 2 is formed. The fixed end 312 has the same configuration as the end of a normal coil spring. On the other hand, the free end portion 313 is folded back from the coil spring body 311 to the coil spring body 311 side from the first extending portion 314 extending in the opposite direction to the coil spring body 311 and the protruding end of the first extension portion 314. It has the folding | returning part 315 and the 2nd extending | stretching part 316 extended | stretched further toward this side from the folding | returning part 315 toward the coil spring main body 311 side.

  The spring support member 121 is fixedly provided between both inner surfaces facing the depth direction of the recess 1x. The spring support member 121 has a fixed end 312 of the coil spring 311 and a positioning groove 121x that can be engaged to position the coil spring in the depth direction at the center in the longitudinal direction.

  The spring support bracket 24 includes a bracket body 241 having a contact portion 241a that contacts the lower surface of the top plate 2 and a hanging portion 241b that is suspended from both ends in the depth direction of the contact portion 241a, and the bracket. It has a support shaft member 242 that is erected between the vicinity of the lower end of the hanging part of the main body and that can be engaged with the free end 313 of the coil spring 31. The pair of hanging parts 241b serve as both ends of the movement of the leg 1 on the free end 313 side of the coil spring 31 in the depth direction. That is, the movement of the leg 1 on the free end 313 side of the coil spring 31 in the depth direction is restricted. On the other hand, the support shaft member 242 is provided apart from the lower surface of the top plate 2. The top plate 2 can be locked at the use position U by the lock mechanism 25. The spring support bracket 24 functions as a free end bracket in the claims.

  In addition, in the present embodiment, the spring support bracket 24 and the free end 313 of the coil spring 31 are located on the use position U side from the predetermined position between the use position U and the storage position S. Only when engaged. Specifically, the total length of the coil spring 31 in a state in which no action is applied to the coil spring 31 is changed from the spring support member 121 of the leg 1 when the top plate 2 is disposed in the storage position S to the spring support bracket 24. The top plate 2 is closer to the storage position S than the predetermined position where the distance from the spring support member 121 to the support shaft member 242 is equal to the total length of the coil spring 31. At this time, the engagement between the coil spring 31 and the support shaft member 242 is released.

  In the present embodiment, an auxiliary biasing mechanism 4 is further provided. This auxiliary biasing mechanism is formed by using a torsion coil spring 41 which is wound around the pivot shaft 232 and has one end supported by the top plate 2 and the other end supported by the leg 1. The top plate 2 is constantly biased toward the storage position S by the biasing force of the torsion coil spring 4.

  Here, the operation and the area relation of each part when the top plate 2 is moved from the use position U to the storage position S will be described below with reference to FIGS.

  When the top plate 2 is disposed at the use position U, as shown in FIG. 6, the fixed end 312 of the coil spring 31 is supported by the spring support member 121 and the free end 313 is supported by the support shaft member 242. ing. The coil spring 31 elastically biases the top plate 2 toward the leg 1 from the lower surface side, that is, toward the storage position S.

  Here, when the top plate 2 reaches a predetermined position between the use position U and the storage position S, as shown in FIG. 7, the distance between the spring support member 121 and the support shaft member 242 is affected by the outside. It becomes substantially equal to the total length of the coil spring 31 in the absence. When the top plate 2 is further moved from the predetermined position toward the storage, the engagement between the free end 313 of the coil spring 31 and the support shaft member 242 is released as shown in FIG. The free end 313 moves between the support shaft member 242 and the lower surface of the top plate 2. Here, the coil spring 31 is guided and moved in a state where the first extending portion 314 is in contact with the support shaft member 242. That is, the first extending portion 314 and the support shaft member 242 function as a guide mechanism that guides the moving direction of the coil spring 31.

  When the top plate 2 reaches the storage position S, as shown in FIG. 9, the width of the spring support bracket 24 is smaller than the width of the recess, so that the lower end of the spring support bracket 24 and the coil spring 31 The free end side is accommodated in the recess 1x of the leg 1, and the remaining part of the coil spring 31 is also arranged in a space defined by the recess 1x and the top plate 2.

  The spring support bracket 24 includes a bracket body having a contact portion 241a that contacts the lower surface of the top plate 2 and a hanging portion 241b that is suspended from both ends in the depth direction, and the hanging portion 241b includes: Since the movement of the leg 1 on the free end 313 side of the coil spring 31 in the depth direction is restricted, the free end 313 side of the coil spring 31 is prevented from shaking in the depth direction of the leg 1 when the table is stored. The coil spring 31 can be stored in a space defined by the recess 1x and the top plate 2 provided in the leg 1. In addition, with such a configuration, it is possible to suppress the occurrence of a problem that the cover 32 that covers the coil spring 31 is sandwiched between the leg 1 and the top plate 2 at the time of storage and is damaged.

  In addition, the free end 313 of the coil spring 31 is interposed via the spring support bracket 24 only when the top plate 2 is on the use position U side from a predetermined position between the use position U and the storage position S. 2, when the top 2 is moved from the storage position S to the predetermined position, the biasing mechanism 3 moves toward the storage position S until the top 2 reaches the predetermined position. No power. Therefore, in the region from the storage position S to the predetermined position, it is not necessary to resist the urging force when the top plate 2 is moved, and the movement from the storage position S to the use position U can be easily performed to some extent. .

  A spring support bracket 24 capable of supporting the free end 313 of the coil spring 31 is provided on the lower surface of the top plate 2, and the spring support bracket 24 connects the free end 313 of the coil spring 31 to the top plate. 2, the free end 313 of the coil spring 31 moves away from the top plate 2 when the top plate 2 moves to the storage position S side from the predetermined position. There is room for the occasion.
