Description

[Detailed Description of the Invention] [Industrial field of application] The present invention reduces the bulkiness of the hairdressing and cosmetic shampoo ball in the depth direction when it is stored, and when it is opened, it protrudes in the front direction of the main body frame to facilitate hair washing work. As well as
The present invention relates to an opening / closing device that has a simple structure and can be operated reliably and reliably.

[Conventional technology]

A folding washbasin is disclosed in Japanese Utility Model Publication No. 8-4298. This is composed of a door that can be opened and closed and a washbasin, and this washbasin is pivotally attached via support rods protruding from both ends of a bell crank pivotally attached to the body frame, and the washbasin is an open door. It is supported by being hooked on the upper edge.

[Problems to solve the invention]

In the above-mentioned opening and closing type basin, when the basin is closed, a door is required to cover the outer surface of the basin, and this door needs to be opened and closed separately from the basin, and the pivot point of the basin is movable. However, the basin cannot be projected so much toward the front of the body frame because it is always linked to the opening and closing of the door. Further, the link mechanism for supporting the washbasin becomes complicated.

Further, this method requires two operations of opening and closing the door and tilting the washbasin, and the washbasin is attached to the door, and the fulcrum for opening and closing the door is at the bottom, which makes it easy to perform work such as washbasin and hair washing. In order to allow the ball to protrude from the main body frame, the opening angle becomes large, which lowers the ball position, which is inconvenient for the work and is not preferable. As a solution to this, it is conceivable to provide the storage position of the ball upward, but this is not preferable because the position of the front mirror stand becomes high.

[Means for Solving the Problems]

The lower end of the link that pivotally supports the shamp ball on the side plate of the body frame is pivotally attached, and the guide roller projecting from the shamp ball is rollably fitted and supported in the arc-shaped guide groove formed on the side plate. Further, a tension spring is stretched between the spring stopper protruding from the link and the spring stopper protruding from the main body frame, and the spring is pivotally attached to the spring stopper on the main body frame side and the side plate of the link. The spring stopper so that the link spring stopper is deeper than the vertical line in the closed state of the shamp ball so that it is pulled to the maximum extent on the vertical line connecting the , The position of pivotal attachment of the link to the side plate is determined.

[Action]

When pulling out the shampoo ball, the lower guide roller and the side plate side of the link rotate about the fulcrum, and the link is rocked accordingly. Ascend along the groove. Therefore, the shamp ball ascends while rotating to the horizontal use position and projects from the main body frame.

When the shamp ball is opened and closed, the link also swings, and the spring tension supported by this link causes the spring pressure in the closing direction when the link is past the dead point and in the opening direction when the shamp ball is closed. This makes it possible to open and close the shamp ball smoothly.

〔Example〕

 The present invention will be described below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a main body frame such as a washbasin, a mirror stand, and a hair-washing stand, which are provided with a required shape and equipment so that they can be used in a barber shop, a beauty shop, etc., but it is necessary to omit the illustration above the main body frame. Equipment, such as a mirror, a certification tool, an accessory, a shelf, etc., is provided. Further, a shamp ball 2 is arranged between the inner wall surfaces of the left and right side plates 1a of the body frame 1, and the shamp ball 2 is tilted to open and close. This is the back end side when using shampoo ball 2 for washing hair,
Further, when the shampoo ball is closed and housed in the main body frame, a pivoting portion for tilting the shampoo ball is provided at a position which becomes the lower end side. This shampball pivot is the first
As shown in FIG. 2 and FIG. 2, guide rollers 3 and 3 are rotatably supported by shafts 4 and 4 on both outer sides of the inner end of the shamp ball, and the guide rollers 3 and 3 are attached to the left and right side plates. The guide grooves 1b, 1b formed in the arc-shaped long groove formed in 1a are rollably fitted and supported, and the guide grooves 1b are formed.
A lower end of a link 6 pivotally supported by a shaft 5 on a side plate 1a at a higher position is pivotally attached to an outer surface of a shamp ball via a shaft 7. When the strength of the side portion of the shamp ball 2 is weak, a reinforcing link 8 is arranged along the side surface of the shamp ball between the pivot shaft 7 of this link and the pivot shaft 4 of the guide roller 3 as shown in the figure. The shafts 4, 7 may be supported by the reinforcing link 8.

Reference numeral 9 denotes a spring stopper provided on the main body frame 1 and located above the shaft 5. A tension spring 11 is stretched between the spring stopper 9 and the spring stopper 10 provided on the link 6. . When the shamp ball 2 is closed, the spring stopper 9 and the shaft 5
Is on the same vertical line, and the spring stopper 10 is
The shaft 7 is positioned slightly to the right and the shaft 7 to the left. And when the shamp ball is opened, the spring stopper 10
Is to the left of the vertical line.

In the guide groove 1b, the guide roller 3 is located at the lower end position of the guide groove when the shamp ball 2 is housed (closed state), and at the upper end of the guide groove when the shamp ball 2 is in the horizontal opening state when the shamp ball is used. As shown in FIG.

The operation of the shampoo ball opening / closing device configured as described above will be described below.

As shown in FIG. 1, in order to pull out and use the shamp ball 2 from the state where the shamp ball 2 is stored, pull out the puller at the upper end of the shamp ball toward you, and the shamp ball 2 turns about the shaft 4 of the guide roller 3. Then, the upper end of the shamp ball projects toward the front surface of the main body frame, and the vertical state becomes the horizontal state and the state becomes usable. At this time, the guide roller 3 moves in the arc-shaped guide groove 1b from the lower part to the lower part. Since the side surface of the shamp ball is pivotally supported by the lower end of the link 6 pivotally supported by the side plate, the link 6 pivots about the shaft 5, and thus the pivoting of this link is restricted. When the link 6 pivots (swings) from the state shown in FIG. 1, the spring stopper 10 projecting from the link 6 draws an arc-shaped movement locus about the axis 5 as shown in the figure. When the shamp ball is opened and the spring stop 10 moves vertically from the closed position, the spring 11 is stretched. The position on the vertical line becomes the dead point of the spring, and if the spring stopper 10 of the link moves even further leftward from the vertical line, the spring will not shrink.
This force acts as a force for swinging the link 6 further to the left and acts in the opening direction of the shamp ball to smoothly open the ball and prevent it from accidentally closing.

By moving the spring stopper 10 to the left or right of this vertical position, the tensile force of the spring acts not only in the opening direction of the shamp ball but also in the closing direction, so that the spring stopper is closed when the shamp ball is closed. When 10 passes the dead point, the spring force acts in the direction of closing the shamp ball, and it does not deliberately open. FIG. 2 shows the opening / closing operation state of this shampoo ball.

[Effect of device]

According to the present invention, the lower end of the link that pivotally supports the shamp ball on the side plate of the body frame is pivotally mounted, and the guide roller protruding from the shamp ball can be rolled in the arc-shaped guide groove formed on the side plate. And a tension spring is stretched between the spring stopper projecting on the link and the spring stopper projecting on the main body frame, and this spring is connected to the spring stopper on the main body frame side and the link. The spring stopper of the link is deeper than the vertical line when the shamp ball is closed so that it is pulled to the maximum on the vertical line that connects to the axis pivotally attached to the side plate, and when it is open, it is on the front side of the vertical line. Since the spring stoppers and the links are pivotally attached to the side plates, the shampoo ball opening / closing device has a simple structure and a smooth opening / closing operation can be performed. In addition, the work area when opening the shampoo ball is large, and the pivot shaft can be lifted so that even a shampoo ball with a shallow bottom can be lifted to a height with good workability, so that it is easy to do work such as washing hair, and The depth area can be reduced, and the shampoo ball can be opened and closed easily and reliably with one operation.
