[0011] First, an outline of the present invention will be explained. The present invention includes an upper runner 1 having a through hole 2 through which a center rod 3 passes and an insertion groove 17 on its lower end surface, a lower runner 16 having a through hole 2 through which the center rod 3 passes and an insertion groove 17 on its upper end surface, configured to be movable in the longitudinal direction of the center rod 3, a plurality of main ribs 6, connectors 8 connecting the plurality of main ribs 6 at predetermined intervals in a parallel direction, intermediate connectors 13 provided approximately at the middle of the plurality of main ribs 6 in the longitudinal direction, a plurality of support ribs 7, and support rib connectors 18 connecting the plurality of support ribs 7 at predetermined intervals in a parallel direction. The umbrella has a lower end connector 14 provided on a support rib 7 that connects to an intermediate connector 13 provided on the main rib 6, and a connecting wire 10 that connects the intermediate connector 13 and the lower end connector 14 in a bendable manner, and the connector 8 to which the main rib 6 is connected is inserted into the insertion groove 17 of the upper roller 1, and the support rib connector 18 to which multiple support ribs 7 are connected is inserted into the insertion groove 17 of the lower roller 16, so that the multiple main ribs 6 and support ribs 7 are attached integrally to the upper roller 1 or the lower roller 16 and can move in the direction of opening the umbrella.

[0012] The present invention will now be described in detail with reference to the embodiments shown in the drawings. Figure 1 shows a perspective view of the simple assembly one-piece molded umbrella constructed according to this invention. The simple assembly one-piece molded umbrella of this invention can be mass-produced easily and all at once using special molds, and the parts can be easily assembled. Moreover, the umbrella has excellent durability and strength.

[0013] 2 to 7 show the structure of the integrally molded umbrella rib group 5. As can be seen from the figures, the integrally molded umbrella rib group 5 according to the present invention is composed of multiple main ribs 6 and multiple support ribs 7. Furthermore, at the tips of the multiple main ribs 6 and multiple support ribs 7, connecting connectors 8 and support rib connectors 18 are molded integrally with the multiple main ribs 6 and multiple support ribs 7, and are inserted into the upper rung 1 or lower rung 16 to connect them.

[0014] That is, the connectors 8 and the receiving rib connectors 18 are used to connect a plurality of main ribs 6 and receiving ribs 7 at predetermined intervals beforehand in the manufacturing process.

[0015] 2, 4, and 6, the connector 8 or the receiving rib connector 18 is configured to include a long, thin sheet-like fitting body 20 formed so that the tip ends of a plurality of ribs 6 or a plurality of receiving ribs 7 can be arranged in parallel and connected at predetermined intervals, a flexible connecting wire 10 connected to the fitting body 20, and a connector body 9 connected via the connecting wire 10. The connector body 9 is formed to cover the tip ends of the plurality of ribs 6 or a plurality of receiving ribs 7. Furthermore, as can be seen from the figures, the long, thin sheet-like fitting body 20 is configured to include a hook member 11 having a hook portion 12 having a generally groove-like shape on one side thereof.

[0016] Furthermore, an intermediate connector 13 is formed at approximately the longitudinal center position of the main rib 6, which is made of a long bone, by molding it integrally with the main rib 6 so as to cover the main rib 6, and a lower end connector 14 is also provided at the lower end of the receiving rib 7, which is made of a short bone, by molding it integrally with the receiving rib 7 so as to cover the lower end of the receiving rib 7, and the intermediate connector 13 and the lower end connector 14 are molded integrally in a state where they are pre-connected by a connecting wire 10 made of a flexible material (see Figures 3 and 5).

[0017] However, by rolling the integrally molded rib group 5, particularly the elongated sheet-like fitting body 20 at the tip, into a roughly ring shape and inserting it in this state into the ring-shaped insertion groove 17 formed on the lower end of the top wheel 1, multiple ribs 6 can be attached to the top wheel 1 at once with the correct spacing.

[0018] The same is true for the support bone connector 18 integrally molded at the tip of the support bone 7; by rolling its fitting body 20 into an approximately ring shape and inserting it in this state into the ring-shaped insertion groove 17 formed in the runner 16, multiple support bones 7 can be attached to the runner 16 at once with the appropriate spacing (see Figures 9 and 10).

[0019] The configuration of the potter's wheel 1 according to the present invention is shown in Figures 7 and 8. As shown in Figures 7 and 8, the potter's wheel 1 according to the present invention is formed in a roughly cylindrical shape, and has a through hole 2 in the center through which a center rod 3 is inserted.

[0020] Further outside the through-hole 2, an insertion groove 17 is formed, which is a roughly ring-shaped recessed groove into which the hook portion 12 of the fitting body 20 of the connector 8, a component of the integrally molded umbrella rib group 5, fits and locks. In other words, the hook portion 12 provided on one side of the fitting body 20 of the connector 8 locks onto the locking protrusion 15 formed in the insertion groove 17, and multiple ribs 6 are attached to the upper wheel 1 all at once.

[0021] The wheel 1 is attached to the tip of the center rod 3 by simply fitting the tip of the center rod 3 into the through-hole 2 of the wheel 1. In other words, no adhesive such as glue or connecting members such as nails are required.

[0022] Next, the construction of the runner 16 according to the present invention will be described with reference to FIGS. Like the upper potter's wheel 1, the lower potter's wheel 16 also has a through hole 2 through which the center rod 3 passes, but unlike the upper potter's wheel 1, the lower potter's wheel 16 can move freely in the longitudinal direction of the center rod 3 that passes through it.

[0023] As can be seen from Figures 9 and 10, the upper end surface of the lower wheel 16 is provided with a roughly ring-shaped insertion groove 17 into which the elongated sheet-shaped insertion body 20 of the receiving rib connector 18 provided at the tip of the receiving rib 7 shown in Figure 6 fits, and a locking protrusion 15 is formed within the insertion groove 17.

[0024] Therefore, similar to the upper potter's wheel 1, when the fitting body 20 of the receiving bone connector 18 provided at the tip of the receiving bone 7 is made roughly ring-shaped and inserted into the insertion groove 17, the hook portion 12 provided on the fitting body 20 engages with the locking protrusion 15, and multiple receiving bones 7 can be attached to the lower potter's wheel 16 all at once.

[0025] 11 and 13 show the state in which the runner 16 and the plurality of support ribs 7 connected to the runner 16 move in the longitudinal direction of the center rod 3. In particular, FIG. 13 shows the state in which the lower wheel 16 has been moved up to above the center rod 3, and in this state the umbrella is opened and in the open position (see FIG. 1).

[0026] (Manufacturing of simple assembled integrally molded umbrellas using this invention) As mentioned above, in this device, multiple main ribs 6, multiple support ribs 7, connectors 8 and support rib connectors provided at the tips of the multiple main ribs 6 and multiple support ribs 7 for connecting to the upper rung 1 or lower rung 16, intermediate connectors 13 provided at approximately the middle position of the main ribs 6 in the longitudinal direction, lower end connectors 14 provided at the lower ends of the support ribs 7, and connecting wires 10 that flexibly connect the intermediate connectors 13 and lower end connectors 14 are molded as a single unit using a special mold.

[0027] In this embodiment, the ribs 6 and the support ribs 7 are formed in a round rod shape, but are not limited to a round rod shape. Also, the number of the ribs 6 and the support ribs 7 is eight, but are not limited to eight.

[0028] Figure 2 shows the structure of the integrally molded umbrella rib group 5 manufactured by the aforementioned integral molding. It is important that the elongated sheet-shaped fitting body 20 of the connector 8 at the tip of the main rib 6 and the elongated sheet-shaped fitting body 20 of the receiving rib connector 18 at the tip of the receiving rib 7 for the integrally molded umbrella rib group 5 as shown in Figure 2 are roughly ring-shaped, as shown in Figures 4 and 6. Making them roughly ring-shaped allows them to be inserted into the insertion groove 17 in one go, and multiple main ribs 6 or receiving ribs 7 can be accurately attached to the upper rung 1 or lower rung 16 at one go with a specified spacing.

[0029] (Assembly of the simple one-piece molded umbrella according to this invention) As described above, in this device, the elongated sheet-shaped fitting body 20 of the connector 8 at the tip of the ring-shaped main rib 6 as described above and the elongated sheet-shaped fitting body 20 of the receiving rib connector 18 at the tip of the receiving rib 7 can be assembled by inserting them into the insertion groove 17 of the upper turntable 1 or the lower turntable 16, respectively.

[0030] In other words, in this device, multiple main ribs 6 and support ribs 7 are fixedly connected to the elongated sheet-like fitting body 20 of the connector 8 or support rib connector 18 at predetermined intervals in advance, so that by folding this elongated sheet-like fitting body 20 into an approximately ring shape and inserting it into the insertion groove 17 provided in the upper turntable 1 or lower turntable 16, the multiple main ribs 6 or support ribs 7 can be attached to the upper turntable 1 or lower turntable 16 at once with the specified spacing.

[0031] Moreover, as mentioned above, the connecting wire 10 is extremely flexible, so it can smoothly follow the movement of the ribs 6 or the support ribs 7, for example, the opening and closing operation of the umbrella.

[0032] (Conclusion) The umbrella of this invention features an innovative structure called a one-piece molded rib group. That is, it uses an innovatively structured rib group that allows multiple ribs, such as main ribs 6 and support ribs 7, to be molded integrally with precise spacing. The umbrella is comprised of a top pulley 1, a bottom pulley 16, a center rod 3, a handle 4, a one-piece molded rib group 5, a connector 8 and support rib connector 18 with a long, thin sheet-like insert 20 molded integrally with the one-piece molded rib group 5, and an umbrella fabric 19.

[0033] Regarding the connection between the center rod 3 and the handle 4, the center rod 3 is configured so that the handle 4 can be attached to the center rod 3 by fitting the center rod 3 into the handle 4. Therefore, this connection does not require connecting members such as glue or nails.

[0034] The integrally molded umbrella rib group 5 is connected and integrated with the connector 8 equipped with the insert body 20, which is a long, thin sheet-like member, and the receiving rib connector 18, as mentioned above, and can be formed in one go using a special mold and special machine. This makes it possible to extremely efficiently omit the work required for the conventional processing of complex umbrella parts and the assembly of umbrellas.

[0035] In addition, the hook member 11 formed on one side of the fitting body 20 of the connector 8 and the receiving rib connector 18 is provided with a groove-shaped hook portion 12, and by inserting the hook portion 12 into the insertion groove 17 of the upper wheel 1 or the lower wheel 16, the umbrella is connected in a simple and stable structure, so that the umbrella can maintain its durability even when opened and closed repeatedly.

[0036] In other words, the structure of this invention is simple, but extremely easy to assemble, and at the same time, the strength of the umbrella is taken into consideration, making it possible to provide a lightweight, practical, and innovative umbrella.

[0037] As mentioned above, this device employs an innovative one-piece molded umbrella rib group 5, which includes an upper roller 1, a lower roller 16, a center rod 3, a handle 4, and umbrella fabric 19. The one-piece molded umbrella rib group 5 is composed of multiple long ribs 6, short ribs 7, long, thin sheet-shaped connectors 8, and connector rib connectors 18, which can be formed all at once using special molds and special machines.

[0038] A hooking member 11 having a groove-like hooking portion 12 is provided on one side of the elongated sheet-shaped fitting body 20 of the connector 8 and the receiving rib connector 18, and the hooking portion 12 is engaged with the engaging protrusions 15 in the insertion grooves 17 of the upper and lower wheels 1 and 16, respectively, to obtain a stable engaging state, which has the advantage of allowing multiple main ribs 6 or receiving ribs 7 to be smoothly attached while maintaining appropriate spacing.
