JP 2011-5224 A

  However, in the above-described reverse closing umbrella, the second support frame is formed so as to be slidable in the support insertion groove of the first support frame. The movement of the main shaft in the axial direction of the main shaft is limited by the slot into which the first shaft is inserted into the main shaft, and a large force is required before and after the main bone is positioned perpendicular to the axis of the main shaft. There is a possibility that the opening / closing operation cannot be performed smoothly, and further improvement has been desired.

  In view of the above circumstances, the present invention is a reverse closing that can smoothly open and close the bulk fabric (the waterproof cloth in Patent Document 1) while ensuring the strength of the first bone (the first support frame in Patent Document 1). Umbrellas are provided.

  In the first aspect of the present invention, an intermediate rod having a handle on one end side, a first wheel portion fitted to the outside of the intermediate rod and slidably disposed with respect to the intermediate rod, and a first wheel portion A second shaft portion that is fitted to the outside and is slidably disposed with respect to the first wheel portion, and is configured in a triple-shaft structure, with one end rotatably supported with respect to the first wheel portion And a first support bone that is rotatably supported at one end with respect to the second potter's wheel and supported at the other end rotatably with the main bone. In the closed state, the main bone is folded toward the center rod side together with the umbrella fabric, and the surface of the umbrella fabric is housed inside, and the first wheel part is placed on the center rod with respect to the intermediate rod. While sliding to the other end side, center the first wheel part against the second wheel part. This is a reverse closing umbrella that supports the base bone with the first receiving bone to act in a fully opened state by sliding it to the other end side, and is fitted outside the first wheel portion. And a portion that is slidably disposed with respect to the first wheel portion, has a third wheel disposed on one end side of the center rod from the second wheel portion, and one end supports the first rib of the parent bone. It has the 2nd receiving bone supported by the front end side so that rotation is possible, and the other end is rotatably supported with respect to the 3rd wheel.

  According to this, in a series of operations of the master bone from the time when the umbrella fabric is closed to the time when the umbrella fabric is fully opened, the trajectory of the movement of the support portion of the secondary bone to the master bone is the first receiver. Unlike the trajectory of the movement of the support portion of the bone with the main bone, the rotation of the parent bone is hindered, and it is necessary to adjust the movement of both by some means. That is, the framework portion of the reverse closing umbrella is added to the second wheel portion that is movable along the axial direction of the middle rod, and the second wheel that is movable along the axial direction of the middle rod, As the slider crank structure that adjusts the movement of the support portion of the bone receiving bone with the support bone and the movement of the support portion of the first bone receiving bone, the rotation of the parent bone is made smooth.

  Therefore, since it is not necessary to form a groove in the first receiving bone (the first support frame in Patent Document 1), the rotation of the main bone is made smooth while the strength of the first receiving bone is secured, and the opening and closing of the bulk material is performed. The operation can be performed smoothly.

  Further, the master bone has a master bone base portion whose one end is rotatably supported with respect to the first potter's wheel portion, and a master bone main body portion whose one end is rotatably supported by the other end of the master bone base portion. The length of the main bone main body is not longer than the length from the center rod to the outer peripheral edge of the bulk fabric when the bulk fabric is fully opened as viewed from the axial direction of the middle rod, and the second wheel The cylinder is provided with a cylindrical working cylinder portion that extends in the direction of the other end of the center rod and can accommodate the main bone base portion. When it is closed, it is located inside the working cylinder, and when it is fully opened, it is located outside the working cylinder.

  According to this, while the portion supported by the first wheel portion of the main bone base portion is located in the operation cylinder portion when the umbrella cloth is closed, in other words, the main bone base portion is applied inside the operation cylinder portion. During the contact, the rotation of the base part of the master bone is restricted and only the main body part of the master bone is rotated and opened. The opening of the master bone is restricted only to the main bone main body, and the part supported by the first potter's wheel part of the master bone moves to the outside of the working cylinder, so that the master bone turns and the bulk fabric is completely To open.

  Especially when the main bone exceeds the length from the center rod to the outer peripheral edge of the bulk fabric when the bulk fabric is fully opened, and the main bone is bent back toward the handle when the bulk fabric is fully opened. In the case of the umbrella, the opening / closing operation can be smoothly performed by adopting a configuration in which the parent bone is subjected to a step of opening only the main bone main body portion and a step of opening the parent bone base portion.

Also , the end of one end of the center rod of the first wheel portion can come into contact with the third wheel when the first wheel portion is slid to the other end of the center rod with respect to the second wheel portion. An abutting portion is provided, and the second bone or the main bone is formed to be extendable and contractible.

According to this, the contact portion abuts on the third wheel, and the third wheel is slid to the other end side of the intermediate rod and the second rib is reduced to a length corresponding to the operation, or the master bone Is extended to a length corresponding to the operation, so that the rotation of the main bone becomes smooth, which contributes to the smooth opening and closing operation of the bulk material.

  Furthermore, when the contact portion receives and pushes up the third wheel, the second receiving bone pushes in and supports the parent bone, and tension is applied to the bulk fabric so that the tension of the bulk fabric can be improved.

  In addition, the bulk fabric is formed into a bag shape having a primary bulk fabric and an auxiliary bulk fabric, and the secondary bulk fabric is opened in a state where the bulk fabric is completely opened as viewed from the axial direction of the center rod. It overlaps with the main bulk material at a predetermined range from the rod, and is sewn with the main bulk material at the outer peripheral edge. The main bulk material is attached to the end of the other end side of the center rod, and the auxiliary bulk material is the first wheel part. It is attached to the other end of the middle rod, or the main bulk material is attached to the other end of the first rod portion of the middle rod, and the auxiliary bulk material is attached to the other end of the middle rod. It is set as the structure attached with the edge part.

  Thereby, when closing the bulk dough, when the first potter's wheel part is slid to the handle side, the main paddle cloth or the auxiliary paddle cloth to be attached to the end of the other end side of the center rod of the first potter's wheel is The main bulk material and the auxiliary bulk material which are pulled into one end side of the middle bar along the axial direction of the middle bar and formed into a bag shape are perpendicular to the axis of the middle bar, in other words, toward the middle bar. Thus, the main bone is urged to close toward the center rod, and the appearance of the bulk material can be improved. In this case, when closing the bulk fabric, the bulk fabric becomes W-shaped by bending at the stitched portion of the main bulk fabric and the auxiliary bulk fabric as seen from the direction perpendicular to the axis of the center rod. The rainwater can be received at the portion, and rainwater can be prevented from entering the handle.

  Also, if the handle is extended from the end on one end side of the center rod so that the handle portion of the handle is located away from the axis of the center rod, the sliding range of the first wheel portion is increased. It becomes possible to approach the edge of the one end side of the middle bar, and the length of the whole middle bar of the reverse closing umbrella in the axial direction can be shortened.

  In addition, if the handle is detachably formed and can be attached to both ends of the center rod, the handle is replaced with the other end of the center rod when the umbrella is closed, and the handle is stored inside when carrying the umbrella. Rainwater can be prevented from falling.

  The functional action of the bulk dough 100 will be described and described.

  In a series of operations for closing the umbrella cloth 100, when the first wheel part 40 is slid toward the handle 30 from the state shown in FIG. 21B, the main umbrella cloth 101 is moved to the upper end of the middle rod 20. The auxiliary bulk material 102 is attached and fixed at the upper portion of the main bone support portion 48 of the body portion 41 of the first wheel portion 40, and is therefore pulled downward along the axial direction of the intermediate rod 20. .

  At this time, as shown in FIG. 21A, the main bulk material 101 and the auxiliary bulk material 102 formed in a bag shape are directed in a direction orthogonal to the axis of the middle bar 20, in other words, toward the middle bar 20. Gravitate. Then, the main bone 70 attached to the main bulk fabric 101 and the auxiliary bulk fabric 102 is urged so as to be closed toward the middle rod 20, and the appearance of the bulk fabric 100 is improved. . When closing the umbrella cloth 100, the umbrella cloth 100 is bent at the stitched portion between the main umbrella cloth 101 and the auxiliary umbrella cloth 102 when viewed from the direction orthogonal to the axis of the center rod 20, so that the umbrella cloth 100 becomes W-shaped. It becomes possible to receive rainwater at the part of the valley.

  In the reverse closing umbrella 10 having the above-described configuration, the middle rod 20 having the handle 30 on one end side, and the first wheel portion 40 that is fitted to the outside of the middle rod 20 and is slidable with respect to the middle rod 20. And a second wheel portion 50 that is fitted to the outside of the first wheel portion 40 and is slidably disposed with respect to the first wheel portion 40, and is configured in a triple-axis structure, with one end at the first end The main bone 70 that is rotatably supported with respect to the potter's wheel 40 and that is equipped with the umbrella cloth 100, and one end that is rotatably supported with respect to the second potter's wheel 50 and the other end that rotates with the main bone 70. And a first rib 80 that is supported.

  In the state where the bulk fabric 100 is closed, the main bone 70 is folded together with the bulk fabric 100 toward the middle stick 20 side, and the surface 101a of the main bulk fabric 101 of the bulk fabric 100 is housed inside. The first wheel portion 40 is slid to the other end side of the middle rod 20 with respect to the middle rod 20, and the first wheel portion 40 is slid toward the other end side of the middle rod 20 with respect to the second wheel portion 50. By being moved, the umbrella is a reverse closing umbrella that supports and fixes the main bone 70 with the first receiving bone 80 to act on the umbrella cloth 100 in a fully opened state.

  Further, the third wheel 60 is fitted on the outer side of the first wheel part 40 and is slidable with respect to the first wheel part 40, and is disposed on one end side of the center rod 20 from the second wheel part 50. A second bone receiving end that is pivotally supported on the distal end side relative to a portion of the main bone 70 that supports the first bone receiving bone 80 and is pivotally supported on the third wheel 60. 90.

  According to this, in a series of operations of the main bone 70 from when the bulk fabric 100 is closed to when the bulk fabric 100 is fully opened, the locus of movement of the support portion of the second receiving bone 90 with the main bone 70 is moved. Unlike the trajectory of the movement of the support portion of the first receiving bone 80 with respect to the main bone 70, the rotation of the main bone 70 is hindered. Therefore, it is necessary to adjust both movements by some means. That is, in addition to the second wheel portion 50 that is movable along the axial direction of the intermediate rod 20, the third wheel portion 60 that is movable along the axial direction of the intermediate rod 20 is added to the frame portion of the reverse closing umbrella 10. As a slider crank structure that adjusts the movement of the supporting portion of the second receiving bone 90 with respect to the main bone 70 and the movement of the supporting portion of the first receiving bone 80 with respect to the main bone 70, the rotation of the parent bone 70 is smooth It is supposed to be.

  Therefore, since it is not necessary to form a groove in the first receiving bone 80, the rotation of the main bone 70 can be performed smoothly while the strength of the first receiving bone 80 is ensured, and the opening and closing operation of the bulk fabric 100 can be performed smoothly. Can do.

  Further, a master bone portion 71 whose one end is rotatably supported with respect to the first wheel portion 40, and a master bone main body portion 72 whose one end is rotatably supported by the other end of the master bone portion 71. And the length of the main body 72 is equal to or less than the length from the middle rod 20 to the outer peripheral edge of the bulk fabric 100 in a state where the bulk fabric 100 is completely opened as viewed from the axial direction of the middle rod 20. The second handle portion 50 is provided with a cylindrical working cylinder portion 56 that extends in the direction of the other end of the intermediate rod 20 and can store the master bone base portion 71. The portion supported by the first potter's wheel portion 40 is located in the working cylinder portion 56 when the bulk dough 100 is closed, and is located outside the working cylinder portion 56 when the bulk dough 100 is fully opened. .

  According to this, while the portion supported by the first wheel portion 40 of the master bone base portion 71 is located in the operation cylinder portion 56 when the umbrella cloth 100 is closed, in other words, the master bone base portion 71 is operated. While abutting on the inner side of the cylindrical portion 56, the rotation of the main bone base portion 71 is restricted, and only the main bone main body portion 72 is rotated and opened. The opening of the main bone 70 is restricted only by the main bone main body portion 72, and the portion supported by the first wheel portion 40 of the main bone base portion 71 moves out of the operating cylinder portion 56, whereby the main bone base portion 71 rotates. Then, the umbrella cloth 100 is completely opened.

  In particular, when the master bone 70 exceeds the length from the middle rod 20 to the outer peripheral edge of the umbrella fabric 100 in a state where the umbrella fabric 100 is completely opened, and when the umbrella fabric 100 is fully opened, the master bone 70 is on the handle 30 side. In the case of the reverse closing umbrella that curves in a straight line, the opening and closing operation can be performed smoothly by adopting a configuration in which the main bone 70 is subjected to a stage in which only the main bone main body 72 is opened and a stage in which the main bone base 71 is opened. Can do.

  Further, a stopper member 23 that is formed so as to be able to go in and out of the middle rod 20 and that positions the second wheel portion 50 at a predetermined position of the middle rod 20 is disposed, and the first wheel portion 40 has a groove along the axial direction. 41 a is formed, the stopper member 23 is disposed so as to be able to run in the groove 41 a, and the second wheel portion 50 is formed to be engageable with the stopper member 23, and is one end side of the middle rod 20 of the first wheel portion 40. An abutting portion 46c that can come into contact with the third wheel 60 when the first wheel portion 40 is slid toward the other end of the center rod 20 with respect to the second wheel portion 50 is disposed at the end of the first wheel portion. Has been.

  According to this, the second wheel portion 50 is positioned at a predetermined position of the middle rod 20 by the stopper member 23, the abutting portion 46 c is brought into contact with the third wheel 60, and the third wheel 60 is moved to the other portion of the middle rod 20. Since the second receiving bone 90 is reduced to a length corresponding to the operation while being slid to the end side, the rotation of the main bone 70 becomes smooth, which contributes to the smooth opening / closing operation of the bulk material 100.

  Further, when the abutting portion 46c receives and pushes up the third wheel 60, the second receiving bone 90 pushes in and supports the main bone 70 and applies tension to the umbrella cloth 100, thereby improving the tension of the umbrella cloth 100. It can be.

  Further, since there is a time difference between the step of reversing the bulk fabric 100 and the step of applying tension to the bulk fabric 100, a series of operations when opening the bulk fabric 100 is made smooth and necessary for the bulk fabric 100. It is possible to apply a proper tension.

  In addition, a guide portion 42 that protrudes in a direction orthogonal to the direction in which the groove 41 a is formed when viewed from the axial direction of the middle rod 20 is disposed on the outer peripheral surface of the first wheel portion 40. At the end of the rod 20 on the other end side, a locking portion 42a for restricting the movement of the second wheel portion 50 to the one end side of the middle rod 20 is disposed. A release portion 43 formed so as to be able to push the stopper member 23 into the middle rod 20 is disposed at the end located on the end side, and the second wheel portion 50 is orthogonal to the axial direction of the middle rod 20. A lock portion 52 that is movable in the direction and a lock plate portion 55 that can be engaged with the stopper member 23 are disposed, and the lock portion 52 is locked to be locked with the locking portion 42 a of the guide portion 42. A portion 52b is provided.

  And when the latching | locking part 42a and the to-be-latched part 52b latch and the bulk cloth 100 is in the closed state, it restrict | limits that the 2nd wheel part 50 moves to the one end side of the center rod 20, and is bulky. When the dough 100 is opened, the stopper member 23 is pushed into the intermediate rod 20 by the release portion 43 and enters the groove 41a of the first wheel portion 40 and engages with the lock plate portion 55, whereby the second wheel portion 50. Is positioned at a predetermined position of the intermediate rod 20, and the stopper member 23 comes into contact with the lock portion 52 to release the lock between the locking portion 42a and the locked portion 52b. Further, when the bulk dough 100 is closed from the fully opened state, the guide portion 42 and the locked portion 52b slide to guide the second wheel portion 50 to the locked state and the release portion. 43 abuts against the stopper member 23 to release the engagement between the stopper member 23 and the lock plate portion 55, thereby releasing the stop at the predetermined position of the second wheel portion 50.

  According to this, when opening the bulk dough 100, the stopper member 23 is pushed into the intermediate rod 20 by the release portion 43 and is moved into the groove 41a of the first wheel portion 40, whereby the stopper member 23, the lock plate portion 55, Can be engaged, and the locking of the locking portion 42 a and the locked portion 52 b can be released, and the first wheel portion 40 can be slid with respect to the second wheel portion 50.

  In addition, when the umbrella cloth 100 is closed, the locking portion 42 a of the guide portion 42 and the locked portion 52 b of the locking portion 52 are engaged by sliding the first wheel portion 40 with respect to the second wheel portion 50. Since it is stopped and the second wheel portion 50 can be restricted from moving to one end side of the intermediate rod 20, the operability of the opening and closing operation of the bulk dough 100 can be enhanced.

  In addition, when closing the umbrella cloth 100, the engagement between the middle rod 20 and the first wheel portion 40 is released, and the first wheel portion 40 is slidable with respect to the second wheel portion 50 from the second wheel portion 50. The operation at the closing of the bulk dough 100 can be smoothly and stably performed by guiding the potter's wheel portion 50 to the locked state and releasing the stop at the predetermined position of the second potter's wheel portion 50 by the release portion 43.

  Further, if the handle 30 is extended from the end portion on one end side of the center rod 20 so that the handle portion 32 of the handle 30 is located away from the axis of the center rod 20, the first wheel portion The sliding range of 40 can be brought close to the edge on one end side of the middle bar 20, and the length of the whole middle bar 20 in the reverse closing umbrella 10 in the axial direction can be shortened.

  Further, the bulk fabric 100 is formed into a bag shape having a main bulk fabric 101 and an auxiliary bulk fabric 102, and when viewed from the axial direction of the center rod 20, the bulk bulk fabric 100 is completely removed. In the open state, the main bulk material 101 is overlapped with the main bulk material 101 within a predetermined range from the middle rod 20, the main bulk material 101 is attached to the end portion on the other end side of the middle rod 20, and the auxiliary bulk material 102 is attached to the first wheel portion. 40 is configured to be attached to the other end of the middle bar 20.

  As a result, when closing the umbrella cloth 100, the first umbrella portion 40 is slid toward the handle 30, whereby the auxiliary umbrella cloth 102 is pulled toward one end side of the intermediate rod 20 along the axial direction of the intermediate rod 20. Thus, the main bulk material 101 and the auxiliary bulk material 102 are urged so as to be pulled toward the middle bar 20 in a direction orthogonal to the axis of the middle bar 20, in other words, to close the main bone 70 toward the middle bar 20. In addition, the appearance of the umbrella cloth 100 can be improved. Further, when closing the umbrella cloth 100, the umbrella cloth 100 is bent at the stitched portion between the main umbrella cloth 101 and the auxiliary umbrella cloth 102 when viewed from the direction perpendicular to the axis of the center rod 20, and the umbrella cloth 100 becomes W-shaped. Rainwater can be received at a portion that becomes a valley of the fabric 100 and rainwater can be prevented from entering the handle 30 side.

  Further, if the handle 30 is formed so as to be detachable and can be attached to both ends of the center rod 20, when the umbrella is closed, the handle 30 is replaced with the other end of the center rod 20 to carry the umbrella. It is possible to prevent rainwater that has accumulated inside from falling.
