Description

  The present invention relates to furniture with a top plate used in an office.

Conventionally, in a furniture with a top plate, as an aspect of assembling the top plate to the furniture main body in the assembly process, an engagement claw is formed near each corner on the back side of the rectangular top plate, and the engagement claw on the furniture main body side A mode is proposed in which an opening is provided at a position corresponding to, and the engaging claw and the opening are engaged by a sliding operation of sliding the top plate and the furniture body relatively to fix the vicinity of each corner of the top plate. (For example, refer to Patent Document 1).
No. 7-13543

  However, in the furniture with a top plate provided with engaging portions in the vicinity of each corner of the rectangular top plate as in Patent Document 1 described above, the top plate is always subjected to a force pressing the four corners of the top plate downward. In other words, a state in which a force that bends the portion between the engaging portions upward is always applied. Therefore, if you use furniture with a top plate for a long time. Depending on the material of the top plate, the top plate may actually be bent in a mountain shape, so it is not possible to keep the top plate horizontal, especially on the side of furniture between the top plate and the furniture body. Since a gap is formed, it looks bad.

  This invention pays attention to such a malfunction, and provides the furniture with a top plate which has a structure which prevents the bending of a top plate effectively through long-term use.

  In order to achieve such an object, the present invention takes the following measures. That is, the furniture with a top plate according to the present invention includes a top plate and a furniture body that supports the top plate, and the top plate is moved by a sliding operation that relatively slides the top plate and the furniture body. A furniture with a top plate having a first engaging portion capable of engaging the top plate and the furniture main body in the vicinity of each corner, and is arranged at a position interposed in the first engaging portion. A second engaging portion that can engage the top plate and the furniture main body by the sliding operation is provided.

  Here, the top plate may have various shapes such as a rectangular shape, a circular shape, an elliptical shape, etc., but the vicinity of the corner here refers not only to the vicinity of the corner of the polygon, but to the circular shape. In the case of having a top plate with an elliptical shape, it shows an arbitrary plurality of locations that can favorably support substantially the entire surface of the top plate with respect to the furniture body. Further, the number of the second engaging portions is not limited, and for example, two or more second engaging portions may be provided between two first engaging portions.

  In such a case, the first engagement portion is interposed between the first engagement portions while ensuring the convenience of assembly in which the top plate is assembled to the furniture body by a sliding operation. It can be set as the structure which can avoid effectively that the top plate which each fixed each corner vicinity by the engaging part bent with respect to a furniture main body.

  Further, when the top plate is rectangular, in order to more effectively suppress the bending of the top plate, the second engaging portions are arranged at two locations arranged in the longitudinal direction of the top plate. It is desirable to interpose between the first engaging portions. In order to suppress the bending of the top plate more effectively, it is preferable to provide the second engagement portion at the longitudinal center portion of the top plate. In particular, if the second engaging portion is arranged along the edge of the top plate, the top plate and the furniture main body are not only suppressed by the top plate but also actually suppressed. It can also be effectively avoided that a gap is exposed between the two.

  Furthermore, in order to effectively prevent the bending and deformation of the top plate that can be caused by the external force of the user or the like, it is desirable to arrange the second engaging portion on the use edge side close to the user on the top plate.

  Then, the first engaging portion and the second engaging portion are constituted by a claw portion formed on the back surface side of the top plate and an opening portion formed on the upper surface side of the furniture body, and at the slide end position in the sliding operation. When the claw portion and the opening edge of the opening portion are engaged, the return prevention mechanism that prohibits the sliding movement in the return direction from the slide end position to the slide start end side at the slide end position is provided with the claw portion and the opening portion. If it is provided separately, it is possible to effectively avoid imparting a function such as elastic deformation to the claw part and to give the claw part maximum strength.

  Here, the return prevention mechanism includes, for example, a mechanism for screwing the top plate and the furniture body, but is not limited to screw fixing.

  Specifically, the return preventing mechanism is formed on the back surface side of the top plate and can be protruded in a direction perpendicular to the sliding direction in the sliding operation, and the locking portion provided on the furniture body side and capable of locking the elastic claw. And a configuration in which relative movement in the return direction is prohibited by causing the elastic claw to protrude from the furniture body at the slide end position and locking the elastic claw to the locking portion. be able to. By doing so, not only can the claw portion be configured to ensure maximum engagement strength, but the top plate is not used with a separate part such as a screw for the furniture body, that is, a tool is used. It can be assembled without doing. Therefore, the assembly process of the furniture with a top plate can be greatly simplified, and as a result, the manufacturing cost of the furniture with the top plate can be reduced. In addition, when removing the top plate, it is only necessary to slide the top plate in the return direction while releasing the contact state between the elastic claw and the contact portion. it can.

  And if such a furniture with a top plate is applied to a wagon, a wagon in which the top plate is not easily bent and easily assembled can be suitably configured. In particular, in the case of a wagon, by placing the second engagement part near the center in the width direction on the use edge side, the strength of the center part on the use edge side of the wagon that is most susceptible to external force is ensured, and the top plate is bent by the external force. It can be set as the structure which suppressed effectively.

  Moreover, in order to effectively realize the reduction of the number of parts constituting the entire furniture with a top plate and the reduction of the manufacturing cost relating to the mold creation, it is preferable to provide the top plate by integral molding of resin.

  According to the present invention, the first engagement portion is provided by interposing the second engagement portion in the first engagement portion while ensuring the convenience of assembly in which the top plate is assembled to the furniture body by the sliding operation. It can be set as the structure which avoids effectively that the top plate each fixed to each corner vicinity by the joint part will bend with respect to a furniture main body. And it can be set as the furniture with a top plate which can be used suitably over a long period of time by suppressing suitably the bending of a top plate.

  In particular, by arranging the side claw 13 and the notch 23 as the second engaging portion Y in the longitudinal direction of the top plate 1, specifically, in the central portion in the longitudinal direction, the bending can be performed at the place where the top plate 1 is most easily bent. It is supposed to be effectively suppressed. Further, since the side claws 13 and the notches 23 are arranged along the edge of the top plate 1, not only the top plate 1 is actually prevented from being bent, but also the top plate 1 and the wagon body due to the top plate 1 being bent. 2 is effectively avoided from being exposed to the gap.

  In addition, since the second engaging portion Y including the central claw 14 and the central hole 24 is disposed on the side of the use edge 1a close to the user in the top plate 1, the top plate 1 is easily subjected to external force by the user. Reinforcing the use edge 1a side effectively prevents the top plate 1 from being bent by an external force. In particular, in the wagon W according to the present embodiment, the engagement strength of the portion that is most susceptible to external force in the wagon W is effectively improved by being provided at the use edge 1a side of the top plate 1 and in the center in the width direction. .

  Then, at the slide end position in the slide operation when the top plate 1 is assembled to the wagon body 2, the return prevention mechanism Z that prohibits the sliding movement in the return direction from the slide end position to the slide start end side is provided with the claw portion 10 and the opening Since it is provided separately from 20, it is possible to effectively avoid giving the claw part 10 a function of reducing the strength such as elastic deformation, and to ensure the maximum engagement strength for the claw part 10. It is a possible configuration.

  In particular, in the present embodiment, the elastic claw 15 and the locking hole 25 serving as a locking portion constitute a return prevention mechanism Z, and the elastic claw 15 is protruded from the wagon body 2 at the slide end position so that the elastic claw 15 Since the sliding movement in the return direction can be suitably prohibited by bringing the locking surface of the locking plate into contact with the locking edge 251 of the locking hole 25 serving as the locking portion, it is configured separately. In addition to avoiding the provision of a configuration that reduces the strength such as elastic deformation with respect to the claw portion 10 that has been made, it is possible not only to have a configuration that can ensure the maximum engagement strength, but also to attach the top plate 1 to the wagon body 2 Thus, it is possible to easily and quickly assemble without using separate parts such as screws, that is, without using a tool or the like. Therefore, the assembly process of the wagon W can be greatly simplified. And it will contribute to the reduction of the manufacturing cost of the wagon W by greatly simplifying the assembly process.
