Are brought into contact with each other so as to catch each other, and the cylinders are prevented from coming off. Similarly, the outer diameter Rn (o) of the outer circumferential rib of the n-th cylindrical body is set to be larger than the inner diameter of the second inner circumferential rib Rn + 1 (i2) of the (n + 1) -th cylindrical body. When the umbrella covers are contracted by stacking the cylinders, the outer ribs and the second inner rib of the adjacent cylinders abut each other to prevent the cylinders from coming off. Is made. As described above, by forming the ribs on each cylinder as in the present invention, there is an effect that each cylinder of the umbrella cover can be expanded and contracted while always maintaining the connected state.

Further, as described above, the ribs that are located at both ends of each cylindrical body and that prevent the respective cylindrical bodies from coming off are provided in a ring shape over the entire circumference of the cylindrical body. Function to help maintain the roundness of each cylinder. Therefore, even if each cylinder is made of a thin plastic to reduce its weight, the mutual connecting portion can maintain a high rigidity and maintain a reliable connecting state.

In addition, the umbrella cover of the present application is provided with a sword holding cylinder and a valve mechanism is provided in the sword holding cylinder, so that the umbrella is held by the sword holding cylinder.

Further, the inner diameters of the first inner peripheral rib 13 and the second inner peripheral rib 15 of the n-th cylindrical body 12 counted from the smaller diameter side are Rn (i1) and Rn (i2), respectively. If the diameter is Rn (o), the dimensions are set so that the following relationship is satisfied. Rn (o)> Rn + 1 (i1) (1) Rn (o)> Rn + 1 (i2) (2)

On the other hand, the stone-holding cylinder 20 is also made of polypropylene resin, and as shown in FIG. 3, is attached to the outer periphery near one end (right side in the figure) of the cylinder main body 21 having both ends opened. Are formed in the annular direction along the circumferential direction. The cylindrical body 21 is formed so that its outer diameter is smaller than the inner diameter R1 (i1) of the first inner circumferential rib 13 of the first cylindrical body 12a, and can be accommodated in the first cylindrical body 12a. The retaining projection 22 is formed such that its outer diameter is larger than the inner diameter R1 (i1) of the first inner circumferential rib 13 of the first cylindrical body 12a. When the state 10 is extended, the retaining projection 22 comes into contact with the first inner circumferential rib 13 of the first cylindrical body 12a so as to be hooked, and moves toward the distal end side (left side in the figure) of the stone push holding cylindrical part 20. To prevent slippage. A plurality of water drain holes 29 are formed on the peripheral wall of the cylindrical portion body 21 closer to the end than the retaining protrusion 22.

Further, an elastic body 30 is accommodated near the inner rear end of the cylindrical body 21. The elastic body 30 is formed with an insertion hole 31 for pressing and holding a stone butt of the umbrella along the axial direction of the tubular portion main body 21 so as to expand in a tapered shape toward the rear end side. A plurality of drain grooves 32 are also formed on the outer peripheral side along the axial direction (see FIG. 4). A support protrusion 23 is formed on the distal end side of the elastic body 30 so as to protrude annularly from the inner peripheral surface of the cylindrical body 21 to prevent the elastic body 30 from moving to the distal end side. A restricting projection 24 is similarly formed on the rear end side to restrict the elastic body 30 from coming off to the rear end side.

A cap 40 is detachably attached to the distal end opening of the tubular portion main body 21. The cap 40 has a disc-shaped bottom portion 41 that closes the opening of the tube portion main body 21, an outer tube wall 42 that rises vertically from an edge of the bottom portion 41, and a concentric inner wall of the outer tube wall 42. And an inner cylindrical wall 43 formed to stand up in a shape. A screw portion 44 is formed on the inner peripheral surface of the outer cylinder wall 42, and the screw portion 44 is screwed with a screw portion 25 formed on the outer peripheral wall at the distal end of the cylindrical portion main body 21, thereby forming the cap 40. Is detachably attached to the tubular body 21. The outer diameter of the inner cylindrical wall 43 is in contact with the inner peripheral surface of the distal end of the cylindrical main body 21 when the cap 40 is attached, and the outer cylindrical wall 42 and the inner cylindrical wall 43 sandwich the distal end of the cylindrical main body 21. Dimensions are set.

On the other hand, a support wall 26 is provided near the distal end of the tubular body 21 so as to close the inside of the tubular body 21, and a stopper extending toward the distal end of the tubular body 21 at the center thereof. The stopper 27 is formed so as to protrude, and a drain hole 28 is formed around the base of the stopper 27. The stopper 27 is set to have such a size as to close the drain port 45 formed at the center of the bottom 41 of the cap 40 when the cap 40 is attached.

The outer diameter of the cap 40 is formed so as to be larger than the first inner circumferential rib 13 of the cylindrical portion 12 a having the smallest diameter. Prevent dropout.

Next, a method of manufacturing the umbrella cover 10 will be described. First, the cylindrical body 12 as shown in FIG. 2 is formed to have dimensions satisfying the equations (1) and (2). Since the above-described ribs are formed on the respective cylinders 12, they cannot be connected as they are. Therefore, each cylindrical body 12 is immersed in hot water to be softened and deformed in a softened state, and the small-diameter cylindrical bodies 12 are inserted into the large-diameter cylindrical bodies 12 and connected in order. If the shape is adjusted and then cooled after the connection, each cylinder 12 is hardened again, so that the cylinders 12 can be connected so as not to come off from each other. Thereafter, the ram-holding cylinder 20 manufactured in advance is inserted from the rear end side of the umbrella cover 10 with the cap 40 removed. When the cap 40 is attached at the point where the tip of the butt holding cylinder 20 protrudes toward the tip of the cylindrical body 12a having the smallest diameter, the butt holding section 20 is prevented from coming off to the tip side by the retaining projection 22. At the same time, the cap 40 keeps the rear end from coming off, and is connected to the cover body 11.

The umbrella cover 10 of the present invention as described above is used as follows. When the umbrella cover 10 is attached to the umbrella, first, the umbrella butt is inserted from the rear of the umbrella cover 10 in which the respective cylindrical bodies 12 are overlapped and contracted as shown in FIG. The tip of the ram is inserted into the insertion hole 31 of the elastic body 30. At this time, since the insertion hole 31 is opened so as to taper toward the rear, the tip of the ram is set at the insertion hole 31. Smoothly along the perimeter of the wall, it is supposed to be centered at the correct position, and pushed into the back. Further, even if the elastic body 30 is pushed inward by the insertion of the ram, the elastic body 30 does not move because the movement of the elastic body 30 is restricted by the support projection 23. When the stone shovel is pushed far enough to the back, the elastic body 30 is brought into close contact with the stone shovel and the umbrella cover 10 is firmly fixed to the umbrella 12.

Thereafter, when the user grasps the outermost cylindrical body 12 located on the outermost side of the cover body 11 and moves it toward the handle of the umbrella, the cylindrical bodies 12 are aligned. The entire wet portion of the umbrella is covered by the cover body 11 (see FIG. 6). At this time, since the relationship of the above-described formula (1) is established between the first inner peripheral rib 13 and the outer peripheral rib of each cylindrical body 12, the first inner peripheral rib 13 and the outer peripheral rib 13 are formed. The cylinders 14 and 14 are in contact with each other, and the respective cylinders 12 are maintained in a connected state without coming off from each other. When the wet umbrella is covered with the umbrella cover 10 and the umbrella is carried with the umbrella handle facing down, the water droplets adhering to the umbrella and the umbrella and the wall of the cover main body 11 fall downward ( The water droplets first move through the drain hole 29 formed in the cylinder body 21 and enter the interior of the cylinder body 21. Then, the water passes through a water drain groove 32 formed on the outer periphery of the elastic body 30 and a water drain hole 28 formed in the support wall 26, and is stored at the lowermost part of the stone butt holding cylinder 20. If water accumulates in the stone-holding cylinder 20 as described above, if the screw portion 44 of the cap 40 is loosened to the position where the stopper 27 opens the drain port 45, the water accumulated inside can be removed. Drained to

When the umbrella cover 10 is to be removed from the umbrella, the user simply holds the sword holding cylinder 20 with one hand in a state in which the cover body 11 is contracted, and pulls the umbrella in the direction of the handle. Operation may be performed. Also, in the state where the umbrella cover 10 is contracted in this way, the relationship of the above-described formula (2) is established between the outer peripheral rib 14 and the second inner peripheral rib 15 of each cylindrical body 12, The outer ribs 14 and the second inner ribs 15 formed on the respective cylinders come into contact with each other, so that the respective cylinders 12 do not come off from each other, and the connected state is maintained.

As described above, according to the umbrella cover 10 of the present embodiment, when the umbrella cover 10 is expanded and contracted, the ribs formed on the respective cylinders 12 abut against each other so as to be caught on each other. Thus, the connected state is maintained without the cylinders 12 coming off from each other. In addition, since these ribs function as reinforcing ribs, each cylindrical body 12 can be formed thin to reduce the weight.

Further, the umbrella cover 10 is provided with the stone butt holding portion 20 so as to be accommodated in the cylindrical body 12. Therefore, when the umbrella cover 10 is in a contracted state, its length dimension is reduced. Is possible. Further, since the elastic body 30 is provided inside the umbrella cover 10 so as to expand in a tapered shape toward the rear end side, the umbrella cover 10 can be securely fixed to the stone butt of the umbrella. The attachment / detachment operation is also easy.

Further, since the drainage groove 32 is formed on the outer peripheral side of the elastic body 30, it is possible to increase the pressure contact area between the elastic body 30 and the shingle to make it more difficult to get out of the shingle, and to provide the umbrella cover 10. It is easy to collect water droplets inside (toward the tip), and since the support projection 23 prevents the elastic body 30 from moving to the back, the inside of the tip end holding cylinder 20 can be a water storage space. By opening the drain port 45, it is possible to easily discharge water inside the umbrella cover 10 to the outside.
