Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a potter's wheel that slides on the handle of an umbrella when opening and closing the umbrella.

(b) Conventional technology When opening and closing an umbrella, it is necessary to insert the repellent that locks the sliding wheel into the umbrella handle. The repellent has a strong elasticity and protrudes, so it takes a considerable amount of force to directly immerse it with the tip of your finger, and the contact area is small because you press the thick side of the leaf spring with the tip of your finger. Unlocking the potter's wheel was a difficult operation for those with weak fingertips. In order to facilitate this, it has become known that the potter's wheel is indirectly unlocked via a lever that is swingably supported by a shaft of a bearing provided on the potter's wheel. For example, the potter's wheel shown in Fig. 6 is equipped with a lever 2 that is swingably supported by an eyelet 1 to indirectly operate the barb, while the potter's wheel shown in Fig. 7 has a lever 2 that is swingably supported by an eyelet 1. The umbrella is supported swingably by a pin 3, and pushed up by a spring 4 at one end of the lever 2, so that the tip of a repellent-shaped metal piece 5 provided at the other end of the lever passes through a through hole provided in the potter's wheel and the umbrella handle. The protruding end of the metal piece 5 fits into a fitting hole provided in the umbrella handle so as to protrude inside the handle, thereby locking the potter's wheel in a predetermined position.

(c) Problems to be solved by the invention In a sliding potter's wheel that indirectly releases the lock of the reel through a lever provided on the potter's wheel,
In the case of conventional sliding potter's wheels as shown in (b) above, attaching the lever to the potter's wheel body using eyelets or pins required skill and a great deal of effort, so this idea was developed. To provide a sliding potter's wheel that does not require skill and labor for assembling the sliding potter's wheel, and does not require extra materials.

(d) Means for solving the problem To explain the embodiments of this invention in Figures 1 to 5, it consists of a sliding potter's wheel body A and a lever B, both of which are made of elastic synthetic resin. A box-shaped part 7 having a U-shaped cross section is provided on the side surface of the cylindrical part 6 that slides along the umbrella handle C of the main body A, and protrudes along the cylindrical part 6. The U-shaped opening side of the shaped portion 7 communicates with the insertion hole of the umbrella handle.
The end of the box-shaped part 7 on the umbrella bone receiving side is closed, and the opposite end thereof is opened in a U-shape to form a penetrating long groove with both ends left in the side wall of the box-shaped part 7 on the opposite side of the cylindrical part 6. 8, and elastic barb-like elastic protrusions 9 are provided at the open end of the U-shape to face each other along the umbrella handle and protrude like shelf supports at the communicating end of the U-shape. ing.

The lever B has a total length equal to the distance from the closed inner surface of the umbrella bone receiving side of the box-shaped part 7 to the U-shaped opening end, and has a cube-shaped fixed part 10, an elastic part 11, and a free end part. 12, the fixing part 10 is fitted into the U-shaped opening end of the box-shaped part 7, and the lever B is inserted into the box-shaped part 7 through the umbrella handle insertion hole of the box-shaped part, so that the elastic protrusion 9 protrudes When forcibly press-fitting against the pressure, the restoring force of the elastic protrusion 9 causes both sides of the bottom of the umbrella handle side of the fixing part 10 to be elastically supported by the elastic protrusion 9 that protrudes like a shelf support, so that the potter's wheel main body A and the lever are supported. B are firmly connected together.

The elastic part 11 of the lever B is made thin, and its elasticity allows it to easily return to its original position even if it is bent.The elastic part 11 of the lever B is made thicker from the elastic part 11 to the tip, and the tip part is shaped like an umbrella handle. It has a shape suitable for immersing the repellent by bending it parallel to the direction of the arrow.

(e) Action When the lever B is inserted into the box-like part 7 through the cylindrical part 6, the fixing part 10 is automatically fixed by the elastic protrusion 9 at the U-shaped opening, and the long groove 8 As shown in FIGS. 1 and 2, the back surface of the free end 12 of the lever B protrudes, and the free end 12 is pressed with the tip of a finger to release the repellent.

FIG. 5 shows the state when the repellent 13 protrudes.

(f) Effects of the device This device is assembled by simply inserting the lever B into the box-shaped portion 7, and utilizes the elasticity of the elastic portion to hold down the free end and cause the repellent to appear and retract. Since there is no need to provide a bearing as in the conventional case, the skilled work of assembling with eyelets or pins is not required, and the structure is simple and there are few failures.

[Brief explanation of the drawing]

Figure 1 is a partially cutaway front view of the potter's wheel, Figure 2 is a plan view, Figure 3 is a perspective view of the main body, Figure 4 is a perspective view of the lever, and Figure 5 shows the state when the repellent is protruding. The partially cutaway front view, FIGS. 6 and 7 are front views of the conventional example.

Claims (1)

[Scope of utility model registration request] This device is designed to indirectly release the lock of the reel through a lever installed on the potter's wheel.It consists of a sliding potter's wheel body A and a lever B, both of which are made of elastic synthetic resin. A box-like part 7 having a U-shaped cross section is provided on the side surface of the cylindrical part 6 so as to protrude along the cylindrical part 6, and the open side of the U-shape of the box-like part 7 is used as an umbrella handle. The end of the box-shaped part 7 on the umbrella bone receiving side is closed, and the opposite end is opened in a U-shape, leaving both ends in the side wall of the box-shaped part 7 and forming a long through groove. 8, an elastic protrusion 9 is provided at the open end of the U-shape so as to face the communicating end of the U-shape and protrude like a shelf support, and the entire length of the lever B is connected to the box-shaped part 7. The distance from the closed inner surface of the umbrella bone receiving side to the open end of the U-shape is equal, and it consists of a cube-shaped fixed part 10, an elastic part 11 and a free end part 12,
The fixing part 10 is assembled by fitting into the U-shaped opening end of the box-shaped part 7 and forcibly press-fitting the lever B into the box-shaped part 7 against the protrusion of the elastic protrusion 9.
