Description

  The present invention relates to a furniture with a flap top plate that can perform a flap operation between a use posture and a flip-up posture.

  Conventionally, a pair of left and right legs, top plates arranged on the legs, and a frame for connecting the legs to each other, both ends of the top board are jumped from the posture of use to each leg. There is known a flap table that is supported so as to be able to perform a flap operation until the raising posture (see, for example, Patent Document 1).

  In such a flap table, since the top plate is supported only at the left and right ends, the center portion may bend downward when a load is applied to the top plate. In order to suppress such bending, it has been considered that a projection for receiving the lower surface of the top plate is provided on the upper surface of the frame.

  However, in such a case, only when the top plate is in a use posture, the top plate and the projection come into contact with each other to prevent the top plate from being bent. On the way from the posture to the use posture, there is a possibility that a finger may be pinched between the top plate and the projection on the frame, and some countermeasure has been desired.

JP 2008-110148 A

  An object of this invention is to provide the furniture with a flap top plate which can suppress the bending of a top plate, suppressing the pinching of the top plate on the way from the raising position to the use posture.

The present invention employs the following configuration in order to solve the above-described problems. That is, the furniture with a flap top plate according to the present invention includes a pair of legs, a top plate arranged on the legs, and both ends of the top plate are flipped up from the use posture to each leg. A top plate support mechanism that forms a pair of left and right plates that are supported so that a flap operation can be performed between them, a connection beam that connects these two top plate support mechanisms or the legs, and a lower surface of the top plate, A top plate deflection preventing member having an abutment surface capable of abutting against the connection beam in a use posture, and the top plate support mechanism axially supports the top plate on the legs via a main shaft. The connecting beam is arranged with the main shaft different from the axial center, and the top plate deflection preventing member is located closer to the main shaft than the contact surface, and the contact surface In the motion region from the flip-up posture to the use posture. And characterized in that having a facing surface adjacent via the degree of clearance is not always user's finger from entering the outer peripheral surface of the connecting beam Te.

  Here, “proximity” means that the facing surface of the top plate deflection preventing member and the outer peripheral surface of the connection beam approach each other through a minute gap that does not allow the user's finger to enter. Further, “sliding contact” means that the opposing surface of the top plate deflection preventing member and the outer peripheral surface of the connecting beam are in contact with each other so as to slide.

  If it is such, in a use attitude | position, a top plate will be supported by a connection beam via the top-plate bending | flexion prevention member provided in the lower surface of the top plate other than the left-right top-plate support mechanism or a leg. Therefore, it is possible to suppress the downward deflection of the top plate, and at the same time, the top plate deflection member has an opposing surface. Finger pinching between the top plate deflection preventing member and the connecting beam can be suppressed.

  It is preferable that the top plate deflection preventing member is disposed at the center in the left-right direction of the top plate where the deflection in the use posture is most likely to occur.

  As a preferable aspect of the top plate deflection preventing member, a member provided with an abutting plate having the abutting surface and an opposing surface on an outer edge can be cited.

  Preferably, the top plate deflection preventing member is provided with a mounting portion for mounting on the lower surface of the top plate between two contact plates having the same shape.

  As a preferable aspect of the outer peripheral surface of the connection beam, one having a circular shape in cross section can be cited.

  Since the present invention is configured as described above, there is provided a furniture with a flap top plate that can suppress the deflection of the top plate while suppressing finger pinching on the way from the flip-up posture of the top plate to the use posture. be able to.

  Since the top plate deflection preventing member 8 is provided with a mounting portion 83 for mounting on the lower surface 21 of the top plate 2 between two contact plates 81, 81 having the same shape, the connection beam 4 is provided. The shape of the top plate deflection preventing member 8 can be variously set in accordance with the position and shape to be obtained.

  In the present embodiment, since the outer peripheral surface 41 of the connecting beam 4 has a circular shape in cross section, the shape of the contact surface 82 of the top plate deflection preventing member 8 and the shape of the facing surface 84 are designed. There is also an effect that it is easy.

  The present invention is not limited to the embodiment described above.

  The leg of the present invention is not limited to the above-described embodiment. For example, in addition to a leg body having a reverse Y-shape in side view as in the above-described embodiment, a support and a front leg and a rear leg extending from the lower end of the support to the use end side and the counter use end side, respectively In addition to a leg having an inverted T shape in side view and a leg having an L shape in side view provided with a support and a leg base extending from the lower end of the support to the opposite end side, Various changes are possible. Moreover, the leg which has not only what can stack the other furniture which makes the same structure but a structure which cannot be stacked may be sufficient.

  In addition, the top plate deflection preventing member has an opposing surface that is continuously in contact with the outer peripheral surface of the connection beam in the operation region from the flip-up posture to the use posture continuously to the contact surface, or the connection beam of the connection beam in the operation region. A part may be in sliding contact with the outer peripheral surface, and may be provided with an opposing surface close to the other part. If it is such, according to embodiment mentioned above, the finger pinching between the said top-plate bending | deflection prevention member and a connection beam can be suppressed.

  The top plate deflection preventing member is not limited to a single member, and a plurality of top plate deflection preventing members may be provided. Further, the place where the top plate deflection preventing member is provided is not limited to the center of the top plate and can be variously changed. Furthermore, the top plate deflection preventing member is not limited to a separate body attached to the top plate via an attachment portion, and may be provided integrally with the top plate.

  In addition to the abutment surface of the top plate deflection preventing member that abuts the connection beam in the use posture, the contact surface of the top plate deflection prevention member is applied only when the top plate provided with the top plate deflection prevention member receives a load. It may be in contact.

  The connecting beam is not limited to connecting the left and right top plate support mechanisms, and may be one that connects the left and right legs.

  Further, the shape of the connecting beam can be variously changed, and the shape of the top plate deflection preventing member can be variously changed correspondingly. The abutting surface and the opposing surface of the top plate deflection preventing member are not limited to those provided on the plate-like abutting plate, but are provided on a block shape or a plurality of three or more abutting plates. Also good.

  In addition, various changes may be made without departing from the spirit of the present invention.
