Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a column-shaped upholstery article in which a bending motion is performed by swinging a swing frame by a drive mechanism housed inside a flexible cylindrical peripheral wall to bend the peripheral wall.

[Prior art]

This applicant is a utility model registration application (Practical application 1-7821)
No. 3) In the specification, in response to an external stimulus, as shown in FIG. 7, (b) → (b) → (b) → (c) → (b)
The columnar upholstery item A, which is designed to be flexed in the order of, was introduced. According to this prior application, as shown in FIG. 8, a motor 82, a reduction gear, and a pin-equipped cam 83 are mounted on a base 82 fixed to a bottom cover 81.
A drive mechanism including a drive mechanism is provided, and a pin of the cam 83 of the drive mechanism is inserted into a long hole of a plate 84a of a swing frame 84 which is swingably supported on a base 82 about a horizontal axis. A coil spring 86 is interposed between a tray 84b provided on the upper portion of 84 and an upper lid 85, and the bottom lid 81 to the upper lid 85 are formed in a tubular shape with a flexible material such as a vinyl chloride sheet. Inserted into the peripheral wall 87, and the outer periphery of the pan 84b of the swing frame 84 is locked to a stop ring 88 fixed to the intermediate portion of the inner surface of the peripheral wall 87,
The upper and lower ends of the peripheral wall are joined to the bottom lid 81 and the top lid 85.

[Technical problems to be solved]

As described above, by swinging the swinging frame 84 and locking the swinging frame and the stop ring 88, the side portions of the peripheral wall 87 are alternately pushed out to the left and right, and the can or the column makes a bending movement. First, the efficiency of converting the momentum of the swing frame 84 into the bending motion of the peripheral wall 87 is very low. That is, there are many movement losses. Second, the stop ring 88 on the inner surface of the peripheral wall
Is not easy to fix. Third, the saucer for the swing frame
84b slides on the inner surface of the peripheral wall, resulting in severe wear.
The fold-like bending of the peripheral wall 87 due to the bending tends to obstruct the movement of the swing frame 84. Fourthly, there is a problem that it is difficult to make a large bending motion of the can or the column as a whole. In view of the above points, the present invention reduces the loss of movement of the swing frame, eliminates the need for a retaining ring on the peripheral wall, and prevents the swing of the swing frame from being disturbed by the bending of the peripheral wall caused by bending. It is an object of the present invention to provide a column-shaped upholstery item that can be smoothly swung without being eliminated, and that is capable of performing a large bending motion as a whole.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a columnar upholstery having a bending motion according to the present invention is a lid provided above a rocking frame that is rocked by a drive mechanism attached to a base fixed to a bottom plate. And a columnar upholstery having an elastic member for urging the lid upward from the swing frame, the outer surface of which is formed of a flexible sheet material. A member that guides only the reciprocating movement of the lid in a direction substantially perpendicular to the axis is provided. (B) A connecting member that restricts the maximum distance between the lid and the swing frame is at least the lid and the swing frame. It is provided on one side.

[Action]

When the swing frame swings, the connecting member transmits the swing to the lid. That is, the lid moves back and forth or left and right with respect to the base along with the swing of the swing frame. Since the dimension of the peripheral wall in the height direction is always constant, the height and the inclination of the lid from the bottom plate change as the lid moves. With the movement of the lid, the distance between the lid and the swing frame expands and contracts due to the guiding action of the sliding member.
The lid is always biased by an elastic member in a direction away from the swing frame. Thus, the swinging of the swinging frame causes the upper half of the peripheral wall, which has the appearance of a can or a pillar, to make a bending motion by the movement of the lid.

【Example】

FIG. 1 shows an embodiment in which the construction of the present invention is the simplest. Reference numeral 1 denotes a swinging frame similar to the swinging frame 84 in FIG. 8, which has an interlocking plate 3 formed in a downward opening U-shape and having an elongated hole 2 into which a cam pin of a drive mechanism is inserted. However, the configuration for swinging the swing frame by the drive mechanism is not limited to the combination of the cam with a pin and the elongated hole, and any configuration that converts the rotational motion of the motor into the swing motion of the swing frame is used. Is also good. Reference numeral 4 denotes a fixed plate for fitting and fixing the lid 5, and the upper end of the peripheral wall 6 formed in a tubular shape is bent inside the outer peripheral wall of this fixed plate so as to project on the inner surface of the outer peripheral wall of the fixed plate. The lid 5 is tightly fitted to the fixed dish from above in a state of being locked to the small projection 4a, and the peripheral wall 6 is sandwiched and fixed between the outer peripheral edge of the lid 5 and the outer peripheral wall of the fixed dish 4. As a result, the lid 5 is joined to the peripheral wall 6. At the center of the upper surface of the oscillating frame 1 and the center of the lower surface of the fixed dish, there are interlocking members 7 that project to face each other, are telescopically slidably fitted in a telescopic manner, and guide only in a direction perpendicular to the oscillating frame. It is provided. The interlocking member 7 is fixed to the upper surface of the swing frame 1 and has a cylinder 7a that is opened upward, and a shaft 7b that is fixed to the center of the lower surface of the fixed plate 4 and that is slidably fitted in the hole of the cylinder 7a. Has become.
In order to reduce friction between the cylinder 7a and the shaft 7b, they are made of a material having a small friction coefficient. For example, the cylinder 7a is made of polyacetal and the shaft 7b is made of Duracon. In the illustrated example, the lid 5 is fitted on the fixed plate 4 for convenience,
The fixed dish 4 is omitted, the lid 5 is provided with a shaft 7b, and the lid 5 is provided with a peripheral wall 6a.
May be joined together. Since the cylinder 7a and the shaft 7b are slidably engaged with each other with a minimum amount of play, when the rocking frame 1 is rocked, the rocking motion is fixed.
Is faithfully transmitted to the lid 5 via. Therefore, when the swing frame 1 is swung around the horizontal axis 1 at the lower end thereof, the fixed plate 4 and the lid 5 rotate in conjunction with this, so that the lid 5 and the fixed plate 4 are rotated.
The upper half of the peripheral wall whose upper end is fixed to is bent. A coil spring 8 is provided on the outer periphery of the slidable cylinder 7a and the shaft 7b, and the lid 5 is always biased in a direction away from the swing frame 1, so that the swing frame 1 swings. In the upright state, the lid 5 is separated from the swing frame 1 by the maximum distance, and the peripheral wall is tensioned over the entire circumference, so that the upright state has a perfect shape. The embodiment shown in FIG. 1 can be adopted when the coupling strength between the lid 5 and the peripheral wall 6 is so great that the upper end of the peripheral wall is not torn. In this case, the elastic force of the coil spring 8 is exerted by the peripheral wall. In response to this, the lid 5 is maintained in a state of being separated from the swing frame 1 by the maximum distance. Also at this time, as shown in FIG. 2, the shaft 7b
Is left in a predetermined amount, and when the fixed platen 4 receives a force from the peripheral wall 6 in the swing frame direction, that is, when the can is bent, the shaft 7b is smoothly re-inserted into the cylinder 7a. It can be inserted. When the force of the coil spring 8 is large, the elastic force is applied to the peripheral wall 6
If it is received only by itself, the peripheral wall may tear due to repeated bending. Therefore, in place of the peripheral wall 6, it is desirable to attach a connecting member that regulates the maximum distance between the swing frame 1 and the lid 5. Such a connecting member may be formed of a vertically elongated hole in either one of the cylinder 7a and the shaft 7b, and a pin or the like slidably inserted in the elongated hole in the other. However, such processing is not easy and also causes a reduction in strength between the shaft and the cylinder. 7a and 4 show that both the swing frame 1 and the fixed plate 4 are
Outside of the cylinder 7a and the shaft 7b, each of which extends in the vertical direction, is slidably movable in a certain distance range, and is engaged at a predetermined maximum separation distance to prevent the cylinder 7a and the shaft 7b from coming off. An example in which the regulating member 9 configured to do so is provided will be shown. That is, the regulation member 9 has a locking edge 10 formed on the outer periphery of the upper end portion of the cylindrical regulation member 9a extending upward from the upper surface of the swing frame 1 and downward from the outer periphery of the shaft 7b on the lower surface of the fixed tray 4. A locking claw 11 that is bent inward is provided at the lower end of three or more plate-shaped restricting members 9b that extend to, and the latter restricting member 9b is vertically movably fitted to the outer peripheral surface of the former restricting member 9a. It is configured. With such a configuration, when the can or the pillar is in the upright state, the locking edges 10 and the locking pieces 11 of both the regulation members 9a and 9b are engaged with each other while the peripheral wall 6 is in a tensioned state, and the lid is closed. Since 5 is stopped at the maximum separation distance, the peripheral wall 6 is protected and the life is extended. Thus, in addition to the fitting connection between the cylinder 7a and the shaft 7b, the regulating member 9
If the restriction member 9 is provided, the effect of reinforcing the connecting member 7 can be obtained, so
It is possible to reduce the cost by using a thinner one than that in the illustrated embodiment. Further, when unfolded, the regulating member 9 is slid in a state in which the force from the swing frame 1 can be transmitted to the fixed plate 4 with a sufficiently large strength, and the same guiding action as that of the cylinder 7a and the shaft 7b is achieved. If configured to fulfill, the swinging frame 1 and the lid 5 or the fixed plate 4 may be connected only by the regulating member 9. 5 and 6 show an example in which the cylinder 7a and the shaft 7b in the previous embodiment are omitted and only the restricting member 9 is provided from the above viewpoint, and the restricting member is the fixed tray 4 Is provided so as to project downward on the lower surface of the rocking member, a locking piece 11 is provided at the lower end portion thereof, and a hole 12 through which the regulating member 9 is vertically movable is provided in the upper surface portion of the rocking frame 1. The restricting member 9 is inserted through and the coil spring 8 is held between the swing frame 1 and the fixed plate 4. In this way, when the regulation member 9 provided on the fixed dish side is simply inserted into the swing frame 1, the regulation member 9 reliably transmits the swing motion of the swing frame 1 to the lid 5, In order to secure the required strength, it is necessary to form the regulating member 9 and the upper surface of the swing frame 1 to be thick. Although the above embodiment has a circular can or column appearance, the appearance is not limited to this, and may be a polygon. In this case, the peripheral wall 6 , Fixed plate 4 and lid 5 may have the same polygonal shape. Further, in order to bias the lid upward, it is possible to use an elastic member having a similar action other than the coil spring.

[Effect of device]

As described above, in the columnar upholstery according to the present invention, the swinging movement of the swinging frame is directly transmitted to the lid, and the movement of the lid efficiently bends the peripheral wall of the can or the pillar. , The loss of movement of the rocking frame is reduced, and the peripheral wall does not require a stop ring, and the rocking of the rocking frame is not obstructed by the bending of the peripheral wall due to bending, and the rocking of the rocking frame is smooth. Further, it is possible to make a large bending movement as a whole because it is bent by the rotation of the lid at the uppermost position.
