Description

[Detailed description of the invention] [Technical field to which the invention pertains] This invention relates to a structure for supporting a rotary plate having a support shaft near one end against external force.

[Prior Art and its Disadvantages] The conventional support structure for a rotary plate having a spindle near one end against external forces is such that, for example, taking the lid of a storage device as an example, as shown in Fig. 6A, it is difficult to remove the lid by hand. When rotating the cover 1, there is a support member 2 such as a wall below the end on which force is applied by hand, but a support member 2 such as a wall is provided at the other end so that the rotation of the lid does not get in the way. Not yet.

Therefore, as shown in A and B of the same figure, when a load P ₁ is applied to the center of the support shaft ax, the center part of the support shaft deflects downward, and the load P is applied to approximately the center part of the lid. ₂ , the center portion bends downward and the rear end of the lid warps upward. For this reason, the material of the lid is brittle, and the support shaft
If the distance or the distance in the width direction of the lid is long, it will not be strong enough to withstand the load and the tip of the spindle will come off the bearing, the bearing will be destroyed, or a crack will develop in the center of the rotating plate. As a result, the functions (appearance, strength, etc.) of the rotary plate are significantly deteriorated. Therefore, the user cannot safely place objects on the rotary plate, such as the lid.

[Purpose of this invention] In view of the above points, this invention provides a rotary plate that can support a rotary plate having a spindle near one end without causing deflection or warping even when a load is applied to the rotary plate. The purpose is to provide a support structure for

[Embodiment of this invention] Next, an example in which the support structure according to this invention is applied to the lid of a doll's sofa toy with a storage box will be described with reference to the drawings.

A is the above-mentioned sofa toy, with base 3 (second
It consists of a front plate 4, a backrest 5, and an armrest 6 that stand vertically from a base, and a storage section 7 surrounded by them.

The storage section 7 is divided into upper and lower sections by a partition plate 8, with the upper part being a lid opening/closing type storage part 7a, and the lower part being a drawer type storage part 7b.

The lid 9 of the storage section 7a corresponds to a rotary plate according to this invention, and a support shaft 1 is provided near one end of the backrest side on both the left and right sides.
0, and by rotatably fitting the support shaft 10 into a hole 11 provided in the armrest 6, the storage space of the storage portion 7a can be opened and closed.

The storage section 7b can be pulled out using a handle 13 provided on the front surface of the drawer 12.

The two protrusions B ₁ and B ₂ protruding from the backrest 5 are
This is a support member according to this invention. The protrusion _B1 is provided at the longitudinal center of the backrest 5 and in the rotation range of the rear end 9a of the lid, and its upper surface becomes a concave curved surface along the trajectory drawn by the rear end 9a as the lid 9 rotates. There is. The projection _B2 is provided on the backrest 5 at a position close to the rear upper surface of the lid 9 in the closed state.

Therefore, even if a load is applied to the central portion of the support shaft of the closed lid, the lid is supported by the support shaft and the protrusion _B1 , and therefore has high strength against the load. Further, since the upper surface of the protrusion _B1 is a concave curved surface, it does not get in the way when opening and closing the lid.

However, the support provided by protrusion B ₁ on the rear end is limited to a small area where the protrusion and the rear end contact each other, so if a large load is applied, such as when pushing with a finger, the support provided by protrusion B 1 will be broken and the rear end will be supported by protrusion B ₁ . The end 9a tends to sink along the concave curved surface 14 of the protrusion. In particular, when the front end of the lid is free in the forward direction, such as when it is only placed on the front plate 4, the sinking is not suppressed, and the support shaft 10 may be destroyed due to the sinking. , the lid 9 may sometimes pop out forward. Therefore, by providing a stopper 4a on the upper surface of the front plate that supports the front end of the lid, the sinking can be prevented and sufficient strength can be ensured.

Further, as shown in FIG. 4, if a fan-shaped protrusion 15 whose radius is the distance between the support shaft and the rear end of the lid 9 is provided on the rear lower surface of the lid 9, with the arc facing toward the backrest, the lid can be supported. When a load is applied between the shafts, the arc of the protrusion 15 and the concave curved surface 14 of the protrusion _B1 come into surface contact.
The strength is further increased compared to the previous example. Therefore, the lid 9 can be supported with sufficient strength without providing the stopper 4a on the upper surface of the front plate 4 supporting the front end of the lid 9.

In addition, the protrusion B ₂ prevents upward warping of the rear end 9a of the lid when a load is applied to the center portion of the lid 9.
Alternatively, it is possible to suppress the rear end 9a of the lid 9 from jumping up due to a fall of the soft toy A or a sudden closing operation of the lid 9, and it is possible to prevent the support shaft 10 from coming off from the hole 11.

C is for carrying the sofa toy, etc. with the lid 9.
and a locking member for preventing the drawer 12 from opening or jumping out unnecessarily. This locking member C has a rectangular shape on the front and a substantially L-shape on the side, has a bent portion 18 on the upper part into which the handle 17 of the lid 9 is fitted, and has a rising piece 19 on the lower part.

To attach this locking member, fit the rising piece 19 into the recess 20 provided on the bottom of the base.
Thereafter, the handle 17 of the lid is fitted at the bent portion 18 to fix the lid and the drawer 12. If the protrusion 21 is provided on the inner surface of the bent portion and the handle 17 is provided with a recess 22 corresponding to the protrusion 21 so that they fit elastically, the locking member C will not easily come off.

Furthermore, when removing the locking member, the locking member C can be easily removed by lifting the upper end of the locking member with a finger and disengaging the projection 21 from the recess 22.

The above embodiment is an example in which the support structure according to this invention is applied to a doll sofa toy with a storage box, but this invention is not limited to the above, and the support structure according to this invention is not limited to the above. Applicable to all devices equipped with a board. Further, the protrusion supporting one end of the rotating plate may have a shape extending parallel to the longitudinal direction of the one end.

[Effects of this invention] As described above, this invention has a vertical wall on the one end side of a rotating plate having a spindle near one end, and a vertical wall on the lower side of the one end when the rotating plate rotates. Since a protrusion having a concave curved surface along the trajectory to prevent downward deflection is provided, and a protrusion to prevent upward deflection is provided above the one end, even if a load is applied to the rotary plate, the rotary plate will not bend. Since it is supported by the protrusion, deflection and warping are prevented, so that the support shaft will not come off from the bearing, the bearing will not be destroyed, and the rotating plate will not be destroyed.
Moreover, since the protrusion has a concave curved surface having the above-mentioned shape, there is no problem in the rotational operation of the rotary plate.
