Description

Technical Field

[0001] The present invention relates to a connection structure between a middle rod and an umbrella part.

Background Art

[0002] An umbrella generally includes an umbrella cloth, a framework, an upper runner, a lower runner, a middle rod and a handle, and several other umbrella parts. The upper runner and the middle rod are fixed on the upper end side of the middle rod by a pin. Also, a handle for holding the umbrella when using the umbrella is attached to the lower end side of the middle rod.

[0003] The framework of the umbrella is respectively connected and attached to the upper runner and the lower runner that slides in the vertical direction of the middle rod. By operating the lower runner up and down, the umbrella can be opened or closed. In addition, the umbrella cloth is attached on the framework and is configured to operate together with the framework so that the umbrella cloth expands when the umbrella is opened and shrinks together with the framework when the umbrella is closed.

[0004] However, it is very difficult to disassemble an umbrella with the conventional structure without tools, and when it is discarded, it is often discarded without being completely disassembled. However, in recent years, in all fields, there is a demand for promoting resource reuse, manufacturing products, or taking measures against environmental pollution caused by product disposal. In the umbrella manufacturing field, solving these two problems is also required.

[0005] That is, many of the parts of an umbrella use reusable raw materials. For example, umbrella parts made of plastic or the like can be reused, but discarding them not only wastes resources but also causes environmental pollution due to the disposal. Therefore, in the umbrella manufacturing industry, there is a demand for an umbrella structure that can be easily disassembled by hand without using tools, and the above problems are also urgent problems to be solved for the umbrella production industry.

Mode for Carrying Out the Invention

[0011] Hereinafter, modes for carrying out the present invention will be described with reference to the drawings. FIGS. 1 to 5 show a first embodiment of a connection structure between a middle rod and an umbrella part according to the present invention.

[0012] First, the present invention is configured to include an umbrella part 1 and a locking fixture 2. Here, the locking fixture 2 is composed of at least two parts in a cracked state and is configured to form a cylindrical shape when connected. However, it is not limited to this configuration, and it may be composed of two or more parts. In this embodiment, the umbrella part 1 will be described as an umbrella part having a part called an upper pulley.

[0013] The umbrella part 1 has a pulley forming part 11 having a substantially cylindrical shape. The pulley forming part 11 having a cylindrical shape is configured as a member whose inner diameter of the hollow part is substantially equal to the outer diameter of the middle rod (not shown). That is, the middle rod is configured to be inserted into the hollow part of the pulley forming part 11.

[0014] By the way, as described above, the locking fixture 2 is configured such that two locking fixture units 21 having a substantially semi-circular arc shape are connected to form a locking fixture 2 having a substantially cylindrical shape.

[0015] That is, as shown in FIG. 2, the locking fixture unit 21 has a substantially semi-circular arc shape, and the inner peripheral surface of the locking fixture unit 21 is configured with a curved surface 212 having a substantially semi-circular arc shape so as to substantially contact the outer peripheral surface of the pulley forming part 11.

[0016] However, the shape of the locking fixture unit 21 is not limited to the substantially semi-circular arc shape. For example, if the shape of the locking fixture 2 is angular, the shape of the locking fixture unit 21 may be configured to cover it.

[0017] In this embodiment, a mounting hole portion 214 protrudes from the center of the inner surface of one side of the locking fixture unit 21, and a connecting protrusion 216 that can be inserted into the hole of the mounting hole portion 214 to connect the two locking fixture units 21 protrudes from the inner surface of the other side of the locking fixture unit 21. Therefore, when the connecting protrusion 216 is fitted into the mounting hole portion 214, the two locking fixture units 21 are connected, and the locking fixture 2 having a substantially cylindrical shape covers the pulley forming part 11.

[0018] Moreover, even when the connecting protrusion 216 of the other locking fixture unit 21 cannot be inserted into the mounting hole 214 of the one-side locking fixture unit 21, that is, even when they are slightly separated, it does not matter. It is only necessary that the two locking fixture units 21 cover the outer peripheral surface of the locking fixture 2 to such an extent.

[0019] That is, the two locking fixture units 21 may be attached to the spool forming portion 11 in a state where they do not contact each other, as long as the outer peripheral surface of the spool forming portion 11 is substantially covered by the two locking fixture units 21.

[0020] Next, a method of connecting the spool forming portion 11 and the middle rod, which are components constituting the upper spool using the locking fixture 2, will be described.

[0021] As described above, the two locking fixture units 21 each having a substantially semi-circular arc shape that constitutes the locking fixture 2 are attached to the outer peripheral surface of the substantially cylindrical spool forming portion 11.

[0022] First, the connecting protrusion 216 of the locking fixture unit 21 and the mounting hole 214 of the other locking fixture unit 21 are respectively inserted through the first through hole 111 drilled in the side surface of the spool forming portion 11 and the second through hole of the middle rod (not shown) that penetrates the hollow portion of the spool forming portion 11, so that the spool forming portion 11 and the middle rod, in other words, the upper spool which is the umbrella part 1 and the middle rod can be connected and fixed. And by this connection, the locking fixture 2 also covers the outer peripheral surface of the spool forming portion 11.

[0023] Thereafter, a covering member 3 is placed to cover the locking fixture 2 covering the spool forming portion 11. Here, the covering member 3 has a screw hole 31, and by screwing the screw surface of the screw hole 31 onto the screw portion 211 provided on the outer peripheral surface of the locking fixture 2, the covering member 3 can be placed on the locking fixture 2 and firmly attached. And in this embodiment, the covering member 3 functions as the stone protrusion of the umbrella.

[0024] Incidentally, a ring-shaped upper pulley pad 4 is interposed between the umbrella part 1 and the covering member 3. The upper pulley pad 4 is provided with a third through hole 41 having a diameter through which the pulley forming part 11 penetrates and is formed in a ring shape, and has an upper flat surface part 42 to which the center side of the umbrella cloth is attached. Incidentally, it is preferable that not only one upper pulley pad 4 but a plurality of them are stacked and attached.

[0025] The upper pulley pad 4 is installed so that the upper surface part of the upper pulley, that is, the umbrella part 1, becomes flat, and the covering member 3, that is, the stone projection, is screwed and fixed to the outer peripheral surface of the locking fixture 2 and attached, and is used so that rain or the like does not leak from the upper surface of the umbrella cloth into the umbrella.

[0026] Referring to FIG. 4, the covering member 3 which is a stone projection has a cylindrical inner cylinder part 32, and the inner cylinder part 32 is arranged in the cover 34 of the covering member 3 by a connecting rib 33, and the screw surface in the screw hole 31 is screwed on the inner surface of the inner cylinder part 32.

[0027] Incidentally, what is indicated by reference numeral 5 in FIG. 1 or FIG. 5 is a main bone attachment body, one end of which is attached to the upper pulley so as to be swingable in the vertical direction, and a main bone member (not shown) is connected to the other end side to complete the main bone part.

[0028] And both the main bone attachment body 5 and the main bone member are structured to be easily removable by hand without using tools, which is also a major feature of the present invention.

[0029] However, in the first embodiment, an operation of disassembling the umbrella by hand without using tools will be described.

[0030] First, twist the stone projection of the umbrella, i.e., the covering member 3, by hand to remove it from the locking fixture 2. Next, without using tools, pull both locking fixture units 21 outward by hand from the spool forming portion 11 to remove the locking fixture 2. The locking fixture 2 is, for example, composed of a combination of two locking fixture units 21. By pulling these, for example, separating them into two from the outside of the spool forming portion 11 and peeling them off from the outer surface of the spool forming portion 11, the locking fixture 2 can be removed.

[0031] Next, remove the middle rod from the location that constitutes the upper spool of the umbrella part 1, i.e., the spool forming portion 11, without using tools, by hand. Finally, remove the upper spool pads 4 one by one while rotating them upward from the upper spool. (For the method of disassembling the upper spool pads 4 from the upper spool, reference can be made to the content disclosed in Chinese Patent Document CN204048404U.)

[0032] Thus, as described above, in the present invention, without requiring any tools for disassembling the umbrella, the upper spool, middle rod, and stone projection can be completely removed and disassembled by hand, constituting a very convenient umbrella structure.

[0033] Next, referring to FIG. 6, a second embodiment of the connection structure between the middle rod and the umbrella part that can be easily disassembled by hand without using tools will be described.

[0034] In this embodiment, the umbrella part 1 corresponds to the handle portion for holding the umbrella. And the umbrella part 1 (handle) is provided with a spool forming portion 11 that protrudes outward in a substantially cylindrical shape extending from its rear end. This spool forming portion 11 is a cylindrical member having a hollow portion with a diameter substantially equal to the outer diameter of the middle rod (not shown). This is because the middle rod must be able to penetrate into the hollow portion.

[0035] That is, for the attachment of the middle rod to the handle, i.e., the hollow portion of the spool forming portion 11 of the umbrella part 1, the middle rod is inserted and attached into the hollow portion of the spool forming portion 11. And in that case, the locking fixture 2 is used.

[0036] The structure of the locking fixture 2 is the same as that of the first embodiment, and it is composed of two locking fixture units 21. Note that the shape of the locking fixture unit 21 is not limited to the substantially semi-circular arc shape as shown in the figure. As long as a person can remove the locking fixture unit 21 by hand without using tools and the shape allows the locking fixture 2 to be disassembled by hand, it is acceptable.

[0037] In this embodiment, the locking fixture 2 is composed of at least two parts. A mounting hole portion 214 protrudes from the central portion of one side of the locking fixture unit 21, and a connecting protrusion 216 that is inserted into the mounting hole portion 214 and connects the two locking fixture units 21 protrudes from the other side of the locking fixture unit 21.

[0038] Note that the mounting hole portion 214 and the connecting protrusion 216 of the two locking fixture units 21 may not be able to be connected or joined to each other. As long as the two locking fixture units 21 are long enough to cover the spool forming portion 11, it is acceptable.

[0039] For the mounting hole portion 214 and the connecting protrusion 216 of the two locking fixture units 21, they respectively penetrate through the first through hole 111 of the spool forming portion 11 and the second through hole of the middle rod. Then, the umbrella part 1 including the locking fixture 2 and the middle rod are connected.

[0040] Note that a covering member 3 having a substantially cylindrical shape is attached to the outside of the locking fixture unit 21 attached to cover the spool forming portion 11 so that the locking fixture unit 21 does not detach from the spool forming portion 11. A threaded hole 31 is formed in the hollow portion of the covering member 3, and by screwing the threaded surface of this threaded hole 31 onto the threaded surface screwed onto the outer peripheral surface of the locking fixture 2, the locking fixture unit 21, in other words, the locking fixture 2 can be firmly covered.

[0041] With such an attachment, even after the covering member 3 is attached, the reel forming portion 11 and the locking fixture unit 21 can be removed by hand without using tools. The covering member 3 is in an attachment state where it can be removed simply by twisting it off the outer surface of the locking fixture 2 just by twisting.

[0042] The covering member 3 is composed of a member having a substantially cylindrical shape, and the inner wall of its hollow portion is configured as a threaded hole 31 as described above. Therefore, the threaded hole 31 of the covering member 3 can be easily attached by hand by screwing it onto the threaded portion 211 provided on the outer peripheral surface of the locking fixture unit 21, and the two locking fixture units 21 covering the locking fixture 2 can be covered and can also be easily removed.

[0043] By the way, an elastic piece 213 is provided at one end side in the longitudinal direction of the locking fixture unit 21, and a hook 2131 having a hook protruding outward is provided from the outer end of the elastic piece 213. The hook 2131 is configured to engage with the flange 61 of the lower reel 6 when the umbrella is closed, hook the lower reel 6 and stop its movement, so that the umbrella is not automatically opened without artificial operation.

[0044] In this embodiment, when disassembling by hand without using tools, first, the cylindrical covering member 3 is twisted and removed from the locking fixture unit 21.

[0045] Next, the two locking fixture units 21 are sequentially removed, and thus the middle rod is removed from the umbrella part 1, that is, the handle.

[0046] In this way, in the second embodiment, the handle and the middle rod can be completely disassembled by hand without using tools for disassembly, which is extremely convenient.

[0047] The above description is a partial introduction to the embodiments of the present invention and does not limit the scope of rights of the present invention. And it is considered that directly or indirectly applying the specific configurations shown in the present invention to other related technical fields is within the scope of the protection of the rights of the present invention.
