Description

Technical Field

[0001] This utility model relates to a household item, specifically an umbrella and its clamping device. Background Technology

[0002] With the rapid development of society and the gradual improvement of people's lives, people's demands for daily necessities have also increased accordingly. For example, regarding umbrellas, traditional umbrellas are used for sun and rain protection. However, with the increasing prevalence of online shopping and the growing number of delivery riders, riders cannot hold umbrellas while delivering goods by bicycle. Similarly, construction workers and outdoor workers who need to operate their equipment by hand cannot use umbrellas, thus failing to solve the problem of sun and rain protection. In addition, existing umbrellas have long and weak shafts, requiring the user to hold them after opening, making them unsuitable for use by delivery riders or outdoor construction workers in the open or in wind and rain. I have previously filed patent applications with application numbers 2024100369471 and 2024200688114, both titled "An Umbrella and its Combination Device," proposing technical solutions to address the above problems. This application is an improvement on the aforementioned claims. For example, in the umbrella structure of the aforementioned application, manual operation makes it difficult to accurately locate the opening position; and when closing the umbrella, the button is located on the lower extension of the upper ring and is blocked by the umbrella frame, making it inconvenient to insert fingers into the umbrella frame to operate the button; furthermore, the umbrella pole has poor strength; this application proposes an improved solution. This application also proposes a new improved solution for the clamping device. Utility Model Content

[0003] The umbrella described in this utility model can be used together with the clamping device. The umbrella of this application includes an umbrella pole assembly, an upper ring, a lower ring, a frame, and a handle. The frame is installed between the upper and lower rings. The umbrella pole assembly is characterized by: an umbrella pole and a positioning sleeve fitted onto it; the upper end of the umbrella pole is fixedly integrated with the lower end of the upper ring; the upper end of the handle is fixedly integrated with the lower end of the lower ring; the lower end of the umbrella pole passes through the lower ring and the handle, forming a vertically sliding connection; the lower end of the positioning sleeve 12 is fixedly integrated with the upper end of the lower ring 30, or the upper end of the positioning sleeve 12 is fixedly integrated with the lower end of the upper ring 20; a button 52 for opening or closing the umbrella is located on the handle 50.

[0004] There are two methods for fixing the positioning sleeve: one is to fix the lower end of the positioning sleeve to the upper end of the lower ring as one piece, which is the first type of umbrella; the other is to fix the upper end of the positioning sleeve to the lower end of the upper ring as one piece, which is the second type of umbrella. Additionally, the button for controlling the opening and closing of the umbrella is moved to the umbrella handle for easier operation. The above two umbrella types are basic structural umbrellas with the same function. Furthermore, this umbrella is placed on a clamping device above the rider's head, and the umbrella shaft is shorter and stronger than existing umbrella shafts.

[0005] The main function of the positioning sleeve is to position the umbrella when it is open. When operating this umbrella, the upper and lower rings move towards each other along the umbrella shaft to open the umbrella, and move in opposite directions to close it. When opening the umbrella, the upper or lower ring moves towards each other and contacts the positioning sleeve, which is exactly the opening position (no need to slowly move to find the opening position), opening the umbrella and fixing it in the working position; when closing the umbrella, press the button located on the handle (no need to insert fingers into the umbrella ribs), release the umbrella, and under its own restoring force, the umbrella tends to close.

[0006] This umbrella has a simple structure, using a short umbrella pole and a positioning sleeve, which allows the umbrella pole to slide inside the handle for opening and closing. This not only enhances the strength of the umbrella pole but also solves the problem of difficulty in accurately finding the opening position, making the positioning accurate and the opening and closing of the umbrella quick. It is suitable for use on this clamping device.

[0007] Based on the two basic umbrella types mentioned above, the following umbrella structures are derived. The following examples, derived from the first type umbrella (where the lower end of the positioning sleeve is fixedly connected to the upper end of the lower ring to form a single umbrella shaft), are explained below:

[0008] The third type of umbrella, namely the umbrella with a core rod assembly, is characterized by: a core rod assembly installed inside the umbrella shaft, the core rod assembly including a core rod, a coil spring, and a stop plate; the coil spring is fitted onto the core rod, with its upper end pressing against the lower end face of the upper stop inside the umbrella shaft, and its lower end pressing against the upper end face of the lower stop inside the umbrella handle; the shoulder at the upper end of the core rod is located above the upper stop inside the umbrella shaft; the lower end of the core rod passes through the through hole of the upper stop and extends beyond the through hole of the lower stop at the bottom of the umbrella handle, and is fixed by the stop plate. This umbrella is operated manually to open, with spring tension as the primary force, pushing to close the umbrella. When opening the umbrella, hold the umbrella handle with one hand and pull the core rod downwards with the other hand until the upper ring presses against the upper end face of the positioning sleeve, which is the open position of the umbrella. The umbrella is then opened, and the button automatically positions it, ensuring accurate and quick opening operation; after positioning, push the pulled-out core rod upwards and seal it at the bottom of the umbrella shaft with the stop plate. When the umbrella needs to be closed, the positioning connection is disconnected using the button panel. Under the tension of the coil spring, the umbrella shaft and upper ring are pushed upwards, closing the umbrella. This structure features a positioning sleeve and core rod support, providing maximum rigidity and rapid positioning. The manual lever operation for opening the umbrella is convenient and quick, relying primarily on spring tension to push the umbrella towards closure.

[0009] The fourth type of umbrella is a dual-function umbrella. It can be used as a regular handheld umbrella or mounted on a clamping device. Its features include: an extension rod connected to the lower end of the umbrella shaft via a hinge shaft, and a locking assembly fitted onto the extension rod. The locking assembly includes a threaded sleeve fitted over the umbrella handle and the extension rod, and a locking nut fitted over the threaded sleeve. The lower end of the threaded sleeve has external threads and spaced clamping bars, while the locking nut has internal threads and a locking lug. A notch is located on the right side of the lower end of the umbrella handle. When the umbrella is mounted on the clamping device in the working position, the extension rod can rotate counterclockwise from bottom to top around the hinge shaft, through the notch on the right side of the lower end of the umbrella handle, to a horizontal position, and is clamped by a clip below the bend on the clamping device. When used as a handheld umbrella, the umbrella is removed from the clamping device, and the locking assembly is used to connect the umbrella handle and the extension rod together, thus increasing the length of the umbrella shaft and creating a handheld umbrella. This umbrella can be used on a clamping device and also handheld, offering two uses in one. The umbrella is operated by pulling down the extension rod to open it and pushing it up to close it. The umbrella pole is supported by a positioning sleeve, ensuring good rigidity and accurate positioning. The manual lever operation for opening the umbrella is convenient and quick.

[0010] The following is a first type of umbrella clamping device: comprising a horizontal connecting rod assembly and a vertical connecting rod assembly; characterized in that: a bend assembly is further connected between the horizontal connecting rod assembly and the vertical connecting rod assembly; the horizontal connecting rod assembly includes a horizontal connecting rod and an umbrella holder mounted at its front end; the bend assembly includes a bend with a connecting clamp at the front of the bend; the vertical connecting rod assembly includes an inner vertical connecting rod and an outer vertical connecting rod fitted thereon.

[0011] There are also upper and lower mounting buckles attached to the vertical outer extension rod; the mounting buckles are used to install the clamping device on the delivery vehicle seat or on the rider (e.g., on the rider's backpack); the upper mounting buckle has a connecting clamp and a fixing clamp fixed to the upper end of the vertical outer extension rod, and fixing rings on both sides; the lower mounting buckle has a fixing clamp fixed to the lower end of the vertical outer extension rod and fixing rings on both sides. The connection between the components is as follows: the rear end (right end) of the horizontal extension rod is inserted into the elbow through the connecting clamp and clamped by the connecting clamp; the upper end of the vertical inner extension rod is fixed into the hole at the lower rear end of the elbow; the lower end of the vertical inner extension rod is inserted into the hole at the upper end of the vertical outer extension rod through the connecting clamp (of the upper mounting buckle) of the upper end of the vertical outer extension rod, and clamped by the connecting clamp.

[0012] The connecting clamp uses a butterfly cap bolt (i.e., a bolt with a butterfly wrench cap) and a concealed nut (i.e., a nut embedded in the recess of the clamping claw, the cross-section of the recess matching the shape of the nut) to clamp the two clamping claws of the horizontal connecting rod. Its advantages are that adjusting the clamping force of the clamping claws can be done by hand by turning the butterfly wrench cap, requiring no other tools; the structure is simple, the operation is reliable, and it is convenient and quick. The concealed nut will not fall off due to incoordination with the bolt's rotation, and it occupies little space and has a clean appearance. The connecting clamp is suitable for connection parts that frequently require disassembly or adjustment; for example, when using the connecting clamp to hold the horizontal connecting rod and the vertical inner connecting rod, the umbrella's horizontal and vertical position can be quickly adjusted to meet the usage requirements of different users; when not in use, the clamp can be loosened, and the connecting rod can be quickly removed from the connecting clamp for storage.

[0013] The fixing clip in the mounting buckle has a similar structure to the connecting clip, except that it uses bolts without butterfly caps and concealed nuts for fastening fixed parts that are not frequently adjusted; the fixing ring is used to fix the umbrella clamping device to the place of use.

[0014] This clamping device has a simple structure, is easy to adjust, has good rigidity, and strong wind resistance.

[0015] The second type of clamping device is a foldable clamping device derived from the first type of clamping device. Its features include: an added steering component located between the elbow and the vertical inner connecting rod; a through groove at the lower rear end of the elbow containing a stop block; a tongue-shaped plate at the upper end of the steering component inserted into the through groove; and a stop edge on the tongue-shaped plate; a butterfly cap bolt shaft fitted with a small coil spring and a positioning washer inserted into corresponding holes in both the elbow and the tongue-shaped plate; a positioning pin on the positioning washer inserted into the elbow and can be further inserted into the corresponding hole in the tongue-shaped plate to secure them together; a concealed nut connected to the other end of the butterfly cap bolt shaft located on the other side of the elbow; and the upper end of the vertical inner connecting rod inserted into the hole at the lower end of the steering component for secure connection. The operating sequence of this clamping device is as follows: When the horizontal connecting rod rotates clockwise from below around the butterfly cap bolt shaft to the horizontal position (working position), the stop block in the through slot is blocked by the edge of the tongue plate. At this time, the butterfly cap bolt shaft can be tightened, and the positioning pin on the positioning washer, which has been inserted into the elbow, can be further inserted into the corresponding pin hole on the tongue plate of the steering component to secure the elbow and the steering component together, ensuring that the horizontal connecting rod is stably fixed in the working position. In addition to the advantages of the above-mentioned connecting clamp structure, when not in use, after removing the umbrella, the butterfly cap bolt shaft can be loosened, and the small coil spring will push the positioning pin out of the tongue plate, thereby disengaging the elbow from the steering component. This allows the horizontal connecting rod to rotate counterclockwise around the hinge shaft and be folded down in place to a position parallel to the vertical outer connecting rod without removing the horizontal connecting rod, reducing the space occupied and facilitating storage.

[0016] The umbrella holder in this clamping device can have various structural forms. One example is characterized by: an umbrella holder body, an umbrella cover, a cover shaft, a locking bolt, and a bolt shaft. The umbrella holder body is an integral part of the middle and rear sections, and is hinged to the umbrella cover via the cover shaft. The bolt shaft is installed in a window in the middle section. One end of the locking bolt has a bolt sleeve fitted onto the bolt shaft, and the other end has a thread and a wing nut fitted onto it, located on the fork of the umbrella cover. The umbrella handle is placed in the umbrella holder, and the wing nut is tightened to fix the handle inside. The rear end of the umbrella holder body has a hole through which the front end of the crossbar is fitted.

[0017] In summary, this umbrella employs a shaft and positioning sleeve structure, reducing the shaft length and making it suitable for use with the clamping device. The positioning sleeve not only strengthens the shaft's rigidity but also serves to position the umbrella during opening, ensuring quick and accurate opening. Umbrellas with a metal core shaft further enhance shaft rigidity, and opening the umbrella only requires pulling the core shaft; a spring then pushes the umbrella to close, making operation convenient and quick. Umbrellas with an extension pole offer dual functionality; opening and closing the umbrella only requires pulling or pushing the shaft, making operation convenient and quick. The first type of clamping device has a simple structure and good rigidity. The connecting and fixing clamps used at the connection points are small in size, provide stable clamping, and are easy to operate. The second type of clamping device, in addition to the performance of the first type, also has a swivel function. When not in use, the crossbar can be folded down and retracted without removing it, reducing space occupation and facilitating storage. This umbrella and its clamping device can be carried on the body or attached to various vehicles, freeing up workers' hands. It is suitable for use by delivery riders, construction workers, and outdoor workers. Attached Figure Description

Detailed Implementation

[0047] Example 1. Type 1 and Type 2 umbrellas.

[0048] Figure 1 is a schematic diagram of the assembly of the umbrella and the clamping device. This umbrella includes an umbrella pole assembly 10, an upper ring 20, a lower ring 30, a frame 40, and a handle 50. The frame 40 is installed between the upper ring 20 and the lower ring 30. Its features are as follows: As shown in Figure 2, the umbrella pole assembly 10 includes an umbrella pole 11 and a positioning sleeve 12 fitted onto the umbrella pole 11. The upper end of the umbrella pole 11 is fixedly integrated with the lower end of the upper ring 20. The umbrella pole 11 has a positioning hole 11A. The upper end of the handle 50 is fixedly integrated with the lower end of the lower ring 30. The lower end of the umbrella pole 11 passes through the lower ring 30 and the handle 50, allowing for slidable up-and-down movement. The positioning sleeve 12 fitted onto the umbrella pole 11 has two fixing methods: one is that the lower end of the positioning sleeve 12 is fixedly integrated with the upper end of the lower ring 30, as shown in Figure 2, which is the first type of umbrella. Figure 2 shows its closed state, and Figure 3 shows its open state. The other fixing method is shown in Figure 4. The upper end is fixed to the lower end of the upper ring 20 and integrated with the umbrella shaft 11, forming the second type of umbrella (open umbrella state). During operation, the upper ring 20 and lower ring 30 move towards each other along the umbrella shaft 11 to open the umbrella, and move in opposite directions to close it. To open the umbrella, push the upper ring 20 downwards with one hand and push the umbrella handle 50 upwards with the other hand until the upper ring 20 (Figure 3) or lower ring 30 (Figure 4) contacts the positioning sleeve 12, i.e., the distance between the upper ring 20 and lower ring 30 is the height of the positioning sleeve 12, which is the open umbrella position. At this time, the umbrella is opened, and the strip-shaped button 52 located on the umbrella handle 50 (… Figure 3 Lock the open umbrella; when you need to close the umbrella, press button 52 to unlock and close the umbrella.

[0049] As shown in Figure 5, button 52 is mounted on a small shaft 53 on the outer surface of umbrella handle 50. When opening the umbrella, under the action of small spring 54, the claw 55 of button 52 presses against the outer surface of umbrella rod 11. When the upper ring 20 and lower ring 30 move towards each other at a distance equal to the height of positioning sleeve 12, button 52, under the action of small spring 54, inserts claw 55 into positioning hole 11A on umbrella rod 11, connecting umbrella rod 11 with umbrella handle 50. This position is exactly the opening position, opening and locking the umbrella. When closing the umbrella, pressing button 52 disengages claw 55, and under the restoring force of the umbrella structure, the umbrella tends to close.

[0050] As shown in Figure 6, there is also an axial guide portion between the umbrella rod 11 and the mating surface, that is: there is an axial protrusion 11B on the outer surface of the umbrella rod 11, and there is a matching groove in the hole of the mating surface such as the positioning sleeve 12 and the umbrella handle 50, so as to ensure that the umbrella rod 11 will not rotate when it moves axially.

[0051] Example 2. The third type of umbrella is an umbrella equipped with a core rod assembly, as shown in Figure 7. The umbrella shaft 11 contains a core rod assembly, which includes a core rod 13, a coil spring 14, and a baffle 15. The coil spring 14 is fitted onto the core rod 13. The upper end of the coil spring 14 presses against the lower end face of the upper sealing block 16 inside the umbrella shaft 11, and the lower end of the coil spring 14 presses against the upper end face of the lower sealing block 51 inside the umbrella handle 50. The shoulder 13A at the upper end of the core rod 13 is located above the upper sealing block 16 inside the umbrella shaft 11. The lower end of the core rod 13 passes through the hole in the upper sealing block 16, extends out to the screw hole of the lower sealing block 51 at the bottom of the umbrella handle 50, and is fixedly connected to the screw hole of the protrusion 15A of the baffle by the external thread of the lower end of the core rod 13. When the umbrella is opened, pull down the baffle 15 at the lower end of the core rod 13, causing the shoulder 13A to move downwards and press against the upper sealing 16, thereby causing the upper ring 20 to move downwards and press against the positioning sleeve 12. After the umbrella is opened and positioned, push the core rod 13 back upwards and screw the external thread of the baffle protrusion 15A into the screw hole at the bottom of the umbrella handle 51 to fix the baffle 15 to the bottom of the umbrella handle 51.

[0052] Example 3. The fourth type of umbrella is a dual-function umbrella that can be used in combination with a clamping device or held by hand as a regular umbrella. Its features are as follows: as shown in Figures 8 and 9, when the umbrella is in the working position, the lower end of the umbrella pole 11 extends to the bottom of the umbrella handle 50. An extension rod 17 connected to the lower end of the umbrella pole 11 via a hinge shaft 17A is installed (the tongue plate 17B at the upper end of the extension rod 17 is inserted into the corresponding groove at the lower end of the umbrella pole 11, and the extension rod 17 is hinged to the umbrella pole 11 by the hinge shaft 17A). There is a notch 56 on the right side of the lower end of the umbrella handle 50. A locking assembly is installed on the extension rod 17 as shown in Figure 10. The locking assembly includes a threaded sleeve 18 that is sleeved on the umbrella handle 50 and the extension rod 17 and a locking nut 19 that is sleeved on the threaded sleeve 18. The lower end of the threaded sleeve 18 has an external thread 18A and spaced clamping bars 18B (Figure 11). The locking nut 19 has an internal thread that mates with the external thread 18A and a locking lug 19A. When this umbrella is used on the clamping device (the structure of the clamping device is as described in Examples 4, 5, and 6), as shown in Figure 1A, the umbrella is in the open (working) position. In this position, the extension rod 17 is not working and must be retracted. At this time, the lower end of the umbrella pole 11 is in the position of passing through the lower end of the umbrella handle 50. The extension rod 17 can be rotated 90 degrees counterclockwise from bottom to top around the hinge axis 17A from the notch 56 on the right side of the lower end of the umbrella handle 50 to the horizontal position, and clamped by the elastic clip 72A below the bend 71 in the clamping device. When used as a handheld umbrella, remove the umbrella from the clamping device. As shown in Figure 10, place the threaded sleeve 18 over the umbrella handle 50 and the extension rod 17 (the threaded sleeve has an anti-rotation axial protrusion and a matching groove as shown in Figure 6 between it and the handle and extension rod 17, not shown here). Insert the lower end of the umbrella handle 50 into the threaded sleeve 18, and use the threaded sleeve 18 to connect the handle 50 and the extension rod 17 together. Place the locking nut 19 on the threaded sleeve 18, and turn the locking nut 19 upwards to tighten the clamping bar 18B shown in Figure 11 through the locking jaw 19A, locking the threaded sleeve 18, the umbrella handle 50, and the extension rod 17 together, increasing the length of the umbrella pole. At this point, the umbrella can be used as a handheld umbrella. This umbrella can be used for work on the clamping device, and after parking near the delivery location by bicycle, it can be removed and used as a handheld umbrella for sun and rain protection, allowing you to walk to the recipient's door. This solution offers two uses for one umbrella and is easy to operate.

[0053] Example 4 is a first type of clamping device for this umbrella, as shown in Figure 1, including a horizontal connecting rod assembly 60 and a vertical connecting rod assembly 80; characterized in that: a bend assembly 70 is also connected between the horizontal connecting rod assembly 60 and the vertical connecting rod assembly 80. The horizontal connecting rod assembly 60 includes a horizontal connecting rod 61 and an umbrella holder 62 mounted at its front end. The bend assembly 70 includes a bend 71 and a horizontal connecting rod connecting clamp 72 at the front end of the bend 71, as shown in Figure 12 as a DD enlarged cross-sectional view. The horizontal connecting rod connecting clamp 72 has two elastic clamping claws 75 fastened by a butterfly cap bolt 73 and a concealed nut 74. The butterfly cap bolt 73 has a butterfly wrench at its right end and a screw at its left end, which is screwed into the concealed nut 74 installed in the recess on the left side of the bend 71. The shape of the recess matches the shape of the nut. As shown in Figure 1, the vertical connecting rod assembly 80 includes an inner vertical connecting rod 81 and an outer vertical connecting rod 82 fitted over it.

[0054] Figure 1 also shows an upper mounting buckle 83 and a lower mounting buckle 86 fitted onto the vertical outer connecting rod 82, used to fix the clamping device at the place of use; as shown in Figure 13, the upper mounting buckle 83 has a vertical outer connecting rod connecting clamp 83A and an upper fixing clamp 84 fixed to the upper end of the vertical outer connecting rod 82, and upper fixing rings 85 located on both sides; as shown in Figure 14, the lower mounting buckle 86 has a lower fixing clamp 86A fixed to the lower end of the vertical outer connecting rod 82 and lower fixing rings 87 located on both sides.

[0055] The connection method between the components is as follows: As shown in Figure 1, the rear end (right end) of the horizontal connecting rod 61 in the horizontal connecting rod assembly 60 is inserted into the elbow 71 through the horizontal connecting rod connecting clamp 72 and is fastened by the connecting clamp 72. The upper end of the vertical inner connecting rod 81 in the vertical connecting rod assembly 80 is fixed in the hole at the lower end of the elbow 71. The lower end of the vertical inner connecting rod 81 is inserted into the hole at the upper end of the vertical outer connecting rod 82 through the vertical outer connecting rod connecting clamp 83A at the upper end of the vertical outer connecting rod 82 and is fastened by the vertical outer connecting rod connecting clamp 83A.

[0056] Example 5. A second type of clamping device is a foldable clamping device derived from the first type of clamping device, as shown in Figure 1A. Its characteristic is that a steering component 76 is added to the first type of clamping device. The steering component is located between the elbow 71 and the vertical inner connecting rod 81. The elbow 71 has a through groove 71A at its lower rear end, with a stop block 71B in the groove. A tongue-shaped plate 77 at the upper end of the steering component 76 is inserted into the through groove 71A. The tongue-shaped plate 77 has a retaining edge 77A, as shown in Figure 15 (a cross-sectional view of GG in Figure 1A). The elbow 71 and the tongue-shaped plate 77 are hinged together using a butterfly cap bolt shaft 79. A positioning washer 78 with a positioning pin 78A is fitted on the right end of the butterfly cap bolt shaft 79. The positioning pin 78A is inserted into the right side of the elbow 71 and can be further inserted into the corresponding hole in the tongue-shaped plate 77. A small coil spring 79B is also fitted on top. The left end of the butterfly cap bolt shaft 79 is a screw, which is screwed into the concealed nut 79A installed in the recess on the left side of the elbow 71; as shown in Figure 1A, the upper end of the vertical inner connecting rod 81 is then inserted into the hole at the lower end of the steering component 76 and fixed. When the horizontal connecting rod 61 rotates clockwise from below around the butterfly cap bolt shaft 79 to the horizontal working position, the stop block 71B in the through groove 71A is blocked by the stop edge 77A of the tongue plate; at this time, as shown in Figure 15, the butterfly cap bolt shaft 79 is screwed in, and the pin 78A on the positioning washer 78 is further inserted into the corresponding pin hole of the tongue plate 77, thereby fastening the elbow 71 and the steering component 76 in the working position. The advantages of this clamping device are: when not in use, as shown in Figure 15, the butterfly cap bolt shaft 79 can be loosened, and the tension of the small coil spring 79B pushes the positioning pad 78 together with the positioning pin 78A out of the tongue plate 77, disconnecting the connection between the elbow 71 and the steering component 76; as shown in Figure 1A, the horizontal connecting rod 61 can rotate 90 degrees counterclockwise around the butterfly cap bolt shaft 79 and hang down (at this time, the umbrella with the extension rod 17 in Figure 1A has been removed from the umbrella holder 62), and is folded together with the vertical outer connecting rod 82, without the need to remove the horizontal connecting rod 61, and can be stored on the spot.

[0057] Example 6. The umbrella holder 62 can take many forms; only one example is given here.

[0058] As shown in Figure 16 (the butterfly nut 66B is not shown in the figure) and its top view 17, the umbrella holder 62 is installed at the front end (left end) of the crossbar 61 and is used to hold the umbrella handle 50. The umbrella holder 62 is characterized by including an umbrella body 63, an umbrella cover 64, a cover shaft 65, a locking bolt 66, and a bolt shaft 67. The umbrella body 63 is an integral part of the middle part 63A and the rear part 63B. The umbrella body 63 is hinged to the umbrella cover 64 via the cover shaft 65. The bolt shaft 67 is installed in the window hole 63C of the middle part 63A. As shown in Figure 18 (the enlarged cross-sectional view of HH in Figure 16), the left end of the locking bolt 66 has a bolt sleeve 66A, which is fitted onto the bolt shaft 67. The right end has a butterfly nut 66B fitted at the threaded part, which is located on the fork 64A of the umbrella cover 64. As shown in Figures 16 and 17, the umbrella handle 50 is placed in the umbrella holder 62. As shown in Figure 18, the fork 64A is screwed in with a wing nut 66B to secure the umbrella handle 50 within the umbrella holder 62. The rear end 63B of the umbrella body 63 has a hole, which is fitted onto the front end (left end) of the crossbar 61 and secured. On the outer surface of the umbrella handle 50 and the inner surfaces of the umbrella body 63 and the umbrella cover 64, there are axial protrusions similar to those in Figure 6 and matching axial grooves (not shown) to prevent relative rotation between the umbrella clamp 62 and the umbrella handle 50.
