Description

The present invention relates to an umbrella-like structure such as an umbrella, a parasol, a Japanese umbrella, a sunshade umbrella such as a beach umbrella or a garden umbrella, and the like.

When the umbrella is closed, the part stretched between the ribs of the umbrella cloth slackens and spreads out, which is an obstacle. Therefore, this slack portion is wrapped around the outside of the umbrella shaft, bundled, and further fastened with a wrapping string. Since this series of operations is performed by hand, if the umbrella cloth is wet due to use on a rainy day, the hands will get wet. As an umbrella for eliminating the annoyance of getting the hands wet, for example, there is one disclosed in Cited Document 1.

This umbrella is shown in FIGS. 11 and 12. The umbrella cloth 101 is provided with a plurality of elastic curved members 102. When the umbrella 100 is opened, the ribs 103 arranged radially stretch the umbrella cloth 101, so that the curved member 102 is elastically deformed into a flat shape. From this state, when the umbrella 100 is closed, the tension of the umbrella cloth 101 by the rib 103 is loosened, so that the curved member 102 is curved, and the slack portion 101a between the rib 103 and the rib 103 of the umbrella cloth 101 is outside the umbrella shaft 104. Wrap around. Then, by wrapping the curved winding string 105 on the outside of the slack portion 101a, the slack portion 101a can be prevented from spreading.

However, in the above-mentioned umbrella 100, since the slack portion 101a of the umbrella cloth 101 is wound around the outside of the umbrella shaft 104, the wet portion of the umbrella cloth 101 is exposed. Therefore, there is a risk of getting the hands and clothes of the user of the umbrella 100 wet.
The present invention has been made to solve such a problem, and an object of the present invention is to provide an umbrella-shaped structure capable of hiding a portion stretched between the ribs of an umbrella cloth by closing the umbrella-shaped structure. To do.

In order to achieve the above object, the umbrella-shaped structure of the present invention moves along the umbrella shaft in accordance with the core material provided in each of the stretched portions stretched between the ribs of the umbrella cloth and the potter's wheel. In addition, the center wheel that can rotate around the umbrella shaft is connected to the core material and the center wheel, and as the lower wheel moves toward the handle side, the ribs are pulled toward the umbrella shaft side and the tension of the umbrella cloth is loosened. A pulling member that pulls the stretched part toward the umbrella shaft side, and a rotating mechanism that rotates the middle wheel around the umbrella shaft as the lower wheel moves toward the handle side and winds the stretched part between the umbrella shaft and the ribs. , Is equipped.
Therefore, when the umbrella cloth is loosened by the ribs when the umbrella-shaped structure is closed, the stretched portion of the umbrella cloth is caught around the umbrella shaft inside the ribs. Therefore, the umbrella-shaped structure can be closed while accommodating the stretched portion of the umbrella cloth inside.

Further, in the umbrella-shaped structure of the present invention, at least a part of the potter's wheel is arranged inside the potter's wheel, and the rotation mechanism is either the inner peripheral surface of the potter's wheel or the outer peripheral surface of the potter's wheel. It has a spiral guide provided on one side and a slider provided on one of the other and movable relative to the spiral guide, and the lower wheel and the middle wheel as the lower wheel moves toward the handle side. If there is a difference in the movement distance between the wheel and the wheel, the slider may move relative to the spiral guide to rotate the potter's wheel around the umbrella axis.

Further, in the umbrella-shaped structure of the present invention, the rotating mechanism may rotate the potter's wheel around the umbrella axis at the final stage of the closing operation.
Further, in the umbrella-shaped structure of the present invention, one end of the pulling member is slidably connected to the core material, and when the middle wheel moves to the handle side to a predetermined position in accordance with the lower wheel, it is pulled by the stopper. The movement of one end of the member may be restricted so that the movement of the potter's wheel may be restricted.
Further, the umbrella-shaped structure of the present invention may be provided with an anti-rotation mechanism for preventing rotation of the potter's wheel around the umbrella axis.

According to the present invention, when the umbrella-shaped structure is closed, the stretched portion of the umbrella cloth can be pulled toward the umbrella shaft side and wound around the umbrella shaft. Therefore, the rain-wet portion of the umbrella cloth can be hidden, and the user's hands, clothes, and the like can be prevented from getting wet.
Further, according to the present invention, when the umbrella-shaped structure is closed, the stretched portion of the umbrella cloth can be accommodated inside the ribs, so that the umbrella cloth is fastened with a wrapping string after the umbrella-shaped structure is closed. It is no longer necessary, and it is possible to eliminate the need for a wrapping string.

Further, according to the present invention, when the umbrella-shaped structure is closed, the stretched portion of the umbrella cloth can be accommodated and hidden inside the ribs, so that the appearance can be refreshed and new. An umbrella-like structure of design can be provided. In this case, if the wrapping string is eliminated, the appearance can be further refreshed, and an umbrella-shaped structure having a more innovative design can be provided.

Further, according to the present invention, when the umbrella-shaped structure is closed, the stretched portion of the umbrella cloth is accommodated so as to be wrapped around the umbrella shaft, so that the stretched portion of the umbrella cloth is not crumpled and is gathered thinly. Can be done.

When the user moves the lower wheel 11 toward the stone tip 9 along the umbrella shaft 5 from the state where the umbrella 1 in FIG. 1 (D) is closed, the receiving bone 8 pushes up the rib 3. As a result, the rib 3 spreads radially (FIG. 2). That is, the umbrella 1 opens (FIG. 1 (A)). Then, when the user moves the lower wheel 11 toward the handle 15 along the umbrella shaft 5 from the state where the umbrella 1 is opened, the receiving bone 8 pulls the rib 3 toward the umbrella shaft 5. That is, the umbrella 1 closes.

Further, the umbrella 1 moves along the umbrella shaft 5 in accordance with the core material 4 provided in the stretched portion 2a stretched between the ribs 3 of the umbrella cloth 2 and the lower pillow 11, and around the umbrella shaft 5. The rotatable middle kuro 14 and the core material 4 and the middle kuro 14 are connected to each other, and as the lower kuro 4 moves toward the handle 15 side, the rib 3 is pulled toward the umbrella shaft 5 side and the tension of the umbrella cloth 2 is loosened. The pulling member 6 that pulls the stretched portion 2a stretched between the ribs 3 of the umbrella cloth 2 toward the umbrella shaft 5 side, and the middle rokuro 14 around the umbrella shaft 5 as the lower rokuro 11 moves toward the handle 15 side. It is provided with a rotation mechanism 16 for winding a stretched portion 2a stretched between the ribs 3 of the umbrella cloth 2 between the umbrella shaft 5 and the ribs 3.

As shown in FIG. 2, one core material 4 is provided between each rib 3. The core material 4 has a linear or rod shape, and is formed of, for example, plastic, resin, metal, or the like. In the present embodiment, the core material 4 is formed of glass fiber reinforced plastic, but the present invention is not limited to this. The core material 4 is provided at a position equidistant from two adjacent ribs 3. The inner end of the core material 4 is rotatably connected to the potter's wheel 10.

The length of the core material 4 is such that when the umbrella 1 is closed, when the middle wheel 14 rotates around the umbrella shaft 5, the stretched portion 2a stretched between the ribs 3 of the umbrella cloth 2 is placed between the umbrella shaft 5 and the ribs 3. It is long enough to be pulled in securely. In the present embodiment, as shown in FIG. 3, the length of the core material 4 is set so that the outer end thereof reaches the vicinity of the outer peripheral edge 2c of the umbrella cloth 2, but it does not necessarily have to be so long. .. The outer end of the core material 4 is attached to the inner side surface 2d of the umbrella cloth 2. A connecting slider 18, which will be described later, is attached to the core material 4.

The tension member 6 has a linear or rod shape, and is formed of, for example, plastic, resin, metal, or the like. In this embodiment, the pulling member 6 is made of glass fiber reinforced plastic. One end 6a of the pulling member 6 is slidably connected to the core material 4, and when the middle wheel 14 moves to the handle 15 side to a predetermined position in accordance with the lower wheel 11, it is fixed to the core material 4. The stopper 23 restricts the movement of one end 6a of the pulling member 6. In the present embodiment, one end 6a of the pulling member 6 is rotatably connected to a connecting slider 18 that can move along the core material 4, whereby one end 6a of the pulling member 6 slides with respect to the core material 4. It is possible and rotatable with respect to the connecting slider 18 (FIG. 4). When the umbrella 1 is opened and closed, the connecting slider 18 slides with respect to the core material 4, so that the connecting position between the core material 4 and the pulling member 6 changes, and the umbrella 1 can be opened and closed. Further, the other end 6b of the pulling member 6 is rotatably connected to the middle wheel 14. As shown in FIGS. 5 and 6, the other end 6b of the pulling member 6 is arranged inside the other end 8b of the receiving bone 8 (on the side of the umbrella shaft 5).

As shown in FIG. 1A, the pulling member 6 is housed in the inner space 12 on the side of the ridge 9 with respect to the receiving bone 8 with the umbrella 1 open. By doing so, when using the umbrella 1, it is possible to prevent the pulling member 6 from getting in the way of the user.

5 and 6 show the lower wheel 11 and the middle wheel 14. FIG. 5 corresponds to the state shown in FIGS. 1 (A) to 1 (c) of the umbrella 1, and FIG. 6 corresponds to the state shown in FIG. 1 (D) of the umbrella 1. The lower wheel 11 and the middle wheel 14 have a cylindrical shape, and at least a part of the middle wheel 14 can be accommodated in the lower wheel 11. In the state where the middle wheel 14 is housed in the lower wheel 11 shown in FIG. 5, the other end 6b of the pulling member 6 is rotatably connected to the head 14a of the middle wheel 14 exposed from the lower wheel 11. There is. As will be described later, the lower wheel 11 cannot rotate around the umbrella shaft 5, whereas the middle wheel 14 can rotate around the umbrella shaft 5. That is, a gap is provided between the middle wheel 14 and the umbrella shaft 5 and between the middle wheel 14 and the lower wheel 11, and the middle wheel 14 can rotate with respect to the umbrella shaft 5 and the lower wheel 11. ing.

The rotation mechanism 16 is provided on either one of the inner peripheral surface 11a of the lower wheel 11 and the outer peripheral surface 14b of the middle wheel 14 and the spiral guide 19 provided on the other. It has a slider 20 that can move relative to each other along the same direction, and when there is a difference in the movement distance between the lower wheel 11 and the middle wheel 14 as the lower wheel 11 moves toward the handle 15, the slider 20 moves. The potter's wheel 14 is rotated around the umbrella shaft 5 by moving relative to each other along the spiral guide 19. In the present embodiment, the slider 20 is provided on the inner peripheral surface 11a of the lower wheel 11, and the spiral guide 19 is provided on the outer peripheral surface 14b of the middle wheel 14. However, the spiral guide 19 may be provided on the inner peripheral surface 11a of the lower wheel 11, and the slider 20 may be provided on the outer peripheral surface 14b of the middle wheel 14.

In the present embodiment, the spiral guide 19 is formed by a spiral groove, and the slider 20 is formed by a convex portion that fits into the spiral guide 19 and slides. However, the present invention is not limited to these, and for example, the spiral guide 19 may be formed of a spiral convex portion, and the slider 20 may be formed of a member having a concave portion that fits into the spiral guide 19 and slides. ..

Two combinations of the spiral guide 19 and the slider 20 are provided at equal intervals in the circumferential direction, for example. If the number of combinations is too small, the middle wheel 14 may rattle with respect to the lower wheel 11, and the umbrella 1 becomes uncomfortable to use. On the other hand, if the number of combinations of the spiral guide 19 and the slider 20 is too large, the frictional force generated when the middle wheel 14 is rotated becomes large, the operability deteriorates, and the usability of the umbrella 1 may deteriorate. Therefore, it is desirable to determine the number of combinations of the spiral guide 19 and the slider 20 in consideration of these balances. In the present embodiment, the number of combinations of the spiral guide 19 and the slider 20 is set to two, but the number of combinations is not necessarily limited to two.

The umbrella 1 is provided with a rotation prevention mechanism 21 that prevents the lower wheel 11 from rotating around the umbrella shaft 5. In the present embodiment, the rotation prevention mechanism 21 is configured by the concave portion 5a provided on the umbrella shaft 5 and the convex portion 11b provided on the lower wheel 11. The recess 5a is provided on the outer peripheral surface 5b of the umbrella shaft 5 along the axial direction thereof. In the present embodiment, the recess 5a is provided by recessing the cylindrical umbrella shaft 5, but the present invention is not limited to this. The recess 5a is provided at least over a range in which the potter's wheel 11 moves. Further, the convex portion 11b is formed by partially projecting the inside of the partition wall 11c provided on the inner peripheral surface 11a of the lower wheel 11, but is not limited to this. By fitting the convex portion 11b into the concave portion 5a, it is possible to prevent the lower wheel 11 from rotating around the umbrella shaft 5 while allowing the lower wheel 11 to move along the umbrella shaft 5.

As for the combination of the concave portion 5a and the convex portion 11b, for example, two sets are provided at equal intervals in the circumferential direction. If the number of combinations is too small, the lower wheel 11 may rattle with respect to the umbrella shaft 5, and the umbrella 1 becomes uncomfortable to use. On the other hand, if the number of combinations of the concave portion 5a and the convex portion 11b is too large, the frictional force generated when the lower wheel 11 moves becomes large, the operability deteriorates, and the usability of the umbrella 1 may deteriorate. Therefore, it is desirable to determine the number of combinations of the concave portion 5a and the convex portion 11b in consideration of these balances. In the present embodiment, the number of combinations of the concave portion 5a and the convex portion 11b is set to two, but the number of combinations is not necessarily limited to two.

Next, it will be described that the stretched portion 2a of the umbrella cloth 2 is automatically wound between the umbrella shaft 5 and the rib 3 only by the user closing the umbrella 1.
In the state where the umbrella 1 of FIG. 1A is open, the middle wheel 14 is housed in the lower wheel 11, and the tip of the middle wheel 14 hits the partition wall 11c of the lower wheel 11 (FIG. 5). From this state, when the user moves the lower wheel 11 toward the handle 15 in order to close the umbrella 1, the receiving bone 8 pulls the rib 3 toward the umbrella shaft 5, and the umbrella cloth 2 stretched by the rib 3 is released. It begins to loosen. Further, the middle wheel 14 moves to the handle 15 side together with the lower wheel 11, and there is no difference in the moving distance between the lower wheel 11 and the middle wheel 14. Therefore, the potter's wheel 14 does not rotate at this stage.

As the lower wheel 11 and the middle wheel 14 move toward the handle 15, the rib 3 and the core 4 are pulled toward the umbrella shaft 5. Then, as the core material 4 is pulled toward the umbrella shaft 5, the connecting slider 18 that connects one end 6a of the pulling member 6 to the core material 4 slides with respect to the core material 4.

Then, as shown in FIG. 1C, when the umbrella 1 is closed to a certain extent, the connecting slider 18 hits the stopper 23 fixed to the core material 4. That is, when the middle wheel 14 moves to a predetermined position in accordance with the lower wheel 11, the movement of one end 6a of the pulling member 6 (slide of the connecting slider 18) is restricted by the stopper 23. Therefore, the middle wheel 14 that has been driven by the lower wheel 11 cannot move to the handle 15 side, and thereafter, it moves only by the lower wheel 11. Therefore, there is a difference in the moving distance between the lower wheel 11 and the middle wheel 14, and the middle wheel 14 is pulled out from the lower wheel 11 while rotating.

As described above, the potter's wheel 14 does not rotate in the states of FIGS. 1 (A) to 1 (C), but rotates in the states of FIGS. 1 (C) to 1 (D). That is, the rotation mechanism 16 rotates the middle wheel 14 around the umbrella shaft 5 at the final stage of the operation of closing the umbrella 1.

The rotation of the center wheel 14 causes the other end 6b of the pulling member 6 to rotate around the umbrella shaft 5, and the entire pulling member 6 is moved so as to be wound around the umbrella shaft 5 so that the core material 4 is connected to the umbrella shaft 5 and the rib 3. Pull into the space between. As a result, the stretched portion 2a of the umbrella cloth 2 to which the core material 4 is attached is pulled in and accommodated between the umbrella shaft 5 and the rib 3. That is, as shown in FIG. 10, the umbrella 1 can be closed while wrapping the stretched portion 2a of the umbrella cloth 2 around the umbrella shaft 5 inside the rib 3.

The rotation mechanism 16 rotates the middle wheel 14 by an amount sufficient to wind up the stretched portion 2a of the umbrella cloth 2.
Then, by stopping the lower wheel 11 at the lower repellent 22, it is possible to prevent the lower wheel 11 and the middle wheel 14 from returning to the stone tip 9 side and prevent the umbrella cloth 2 from spreading.

In this state, as shown in FIG. 6, a part of the middle wheel 14 remains in the lower wheel 11, and the middle wheel 14 does not completely come out of the lower wheel 11.

On the other hand, when opening the closed umbrella 1, the lower wheel 11 may be removed from the lower repellent 22 and moved to the side of the stone tip 9.
At the initial stage of opening, only the lower wheel 11 moves to the side of the stone tip 9, and the middle wheel 14 rotates in the return direction and is housed in the lower wheel 11. Further, the pulling member 6 and the core member 4 return to their original shapes in response to the rotation of the potter's wheel 14, and the stretched portion 2a of the umbrella cloth 2 is pulled out from the space between the umbrella shaft 5 and the rib 3. The middle wheel 14 rotates until it hits the partition wall 11c of the lower wheel 11, and after the hit, it moves together with the lower wheel 11 to open the umbrella 1.

In this way, when the umbrella 1 is closed, the stretched portion 2a of the umbrella cloth 2 is automatically wound around the umbrella shaft 5, so that the user needs to bother to handle the stretched portion 2a of the umbrella cloth 2 by hand. There is no. Therefore, the user's hands do not get wet.
Further, when the umbrella 1 is closed, the stretched portion 2a of the umbrella cloth 2 can be hidden inside. Therefore, the wet portion can be hidden by the rain, and it is possible to prevent the user's hands, clothes, and the like from getting wet.

In the state where the umbrella 1 is closed, the stretched portion 2a of the umbrella cloth 2 can be accommodated so as to be wound around the umbrella shaft 5. Therefore, the closed umbrella 1 can be put together in a thin manner.

Further, since the stretched portion 2a of the umbrella cloth 2 can be hidden in the state where the umbrella 1 is closed, the appearance can be refreshed, and the umbrella 1 having a new design that has never existed can be provided.
Further, when closing the umbrella 1, the stretched portion 2a of the umbrella cloth 2 can be rolled inward, so that it is not necessary to fasten the umbrella cloth 2 with a wrapping string after closing the umbrella cloth 1, and the wrapping string is unnecessary. be able to. And, since the wrapping string can be eliminated, the appearance can be refreshed, and from this point as well, it is possible to provide the umbrella 1 with a new design that has never existed before.

The present invention can be used for umbrella-shaped structures such as rain umbrellas, parasols, Japanese umbrellas, sunshade umbrellas such as beach umbrellas and garden umbrellas.
