BACKGROUND OF THE INVENTION
The present invention relates to an umbrella stand that individually holds umbrellas that are used or carried in rainy weather and the like, and particularly relates to an umbrella stand that has a function of holding an umbrella handle in a locked state.
[0002]
[Prior art]
Conventionally, for example, in public facilities used by an unspecified number of people such as hotels, an umbrella stand for individually holding umbrellas used or carried in rainy weather has been installed. In such an umbrella stand, there is one in which a plurality of umbrella holding devices configured to be able to hold an umbrella handle in a locked state are provided on an upper portion of a stand. As such an umbrella stand locking mechanism, there is a dial lock that is unlocked by rotating a plurality of dials to match a preset unlock number string. Does not have to carry a key for unlocking, and can prevent troubles such as loss of the key. Further, there are dial locks of a type in which an unlock number string can be arbitrarily set, and it is possible to prevent others from knowing the unlock number string and unlocking it illegally. FIG. 13 shows a typical configuration example of a conventional umbrella holding device using such a dial lock.
[0003]
As shown in FIG. 13, this umbrella holding device 100 is opened to the front surface of a body 110, and an umbrella handle H is inserted into an umbrella receiving portion 101 formed in a vertically penetrating manner so that a hook at the tip of the handle H By hooking F on the body 110, the umbrella is held upright. In addition, the umbrella holding device 100 includes a shutter 102 that opens and closes the opening 111 of the umbrella receiving unit 101 and a dial lock 103 that forms a locked state in which the movement of the shutter 102 is restricted. .
[0004]
As shown in FIG. 20, the shutter 102 includes a closing piece 121 for closing the opening 111, and a support 122 having a substantially cylindrical shape as a whole and having a flat surface 122a formed on a side surface. The shutter 102 can rotate around the support portion 122 supported by the support shaft 120. The shutter 102 can open and close the opening part 111 by rotating.
[0005]
As shown in FIGS. 14 and 15, the dial lock 103 is interposed between the three dials 31, the dial shaft 32 serving as the rotation center of the dial 31, and the dial 31 and the dial shaft 32. And three dial bushes 33 fitted onto the dial shaft 32.
[0006]
Each of the dials 31 is rotatable at a fixed position in the axial direction. As shown in FIG. On the other hand, three rectangular window portions 130 are formed on the upper surface of the body 110, and each dial 31 is arranged such that a part of the peripheral surface protrudes from each window portion 130. Yes. Thus, a three-digit number string can be displayed by matching one of the numbers on the peripheral surface of each dial 31 to a predetermined location. Among the number strings, the number string displayed when the dial lock changes from the locked state to the unlocked state is referred to as an unlocked number string.
[0007]
As shown in FIGS. 14 and 15, the dial shaft 32 can be reciprocated so as to take a forward position and a backward position in the body 110 and is always urged in the forward direction. Three protrusions 32b are formed on the peripheral surface. As shown in FIG. 16, a recess 33d that can be engaged with the protrusion 32b is formed on the inner periphery of each dial bush 33. In the dial lock 103, the locked state is formed by disabling the dial shaft 32 from the forward movement position to the backward movement position. More specifically, in the locked state, in FIG. 15, at least one of the three dial bushes 33 is not in the same phase as the projection 32b corresponding to the recess 33d of at least one dial bush.
[0008]
Here, forward (direction) refers to the right direction in FIGS. 14 and 15, and backward (direction) refers to the left direction in FIGS. 14 and 15.
[0009]
As shown in FIG. 16, an inner peripheral gear portion 31 c is formed on the inner periphery of each dial 31. Each dial bush 33 is reciprocally movable on the dial shaft 32, and an outer peripheral gear portion 33c that can be engaged with and disengaged in the axial direction is formed on the outer periphery of the dial bush 33. In the locked state, as shown in FIG. 15, each dial bush 33 is in a retracted position with respect to each dial 31, and the outer peripheral gear portion 33c is engaged with the inner peripheral gear portion 31c. Accordingly, if each dial 31 is rotated in this state, each dial bush 33 rotates with respect to the dial shaft 32. Here, when rotating the dials 31, if the concave portions 33 d of all the dial bushes 33 are in phase with the protrusions 32 b, the dial shaft 32 can be moved from the forward movement position to the backward movement position. Become. At this time, the number sequence displayed on the window 130 is an unlocked number sequence set in advance.
[0010]
From this state, as shown in FIG. 14, if each dial bush 33 takes the forward position with respect to each dial 31, the engagement between the outer peripheral gear portion 33 c and the outer peripheral gear portion 131 c is released, Each dial 31 can rotate relative to each dial bush 33, and the recess 133c of each dial bush 33 engages with each projection 32b, so that each dial bush 33 cannot rotate with respect to the dial shaft 32. . Therefore, it is possible to rotate only each dial 31 while each recess 33d and each projection 32b are in the same phase. Here, if the number sequence displayed on the window 130 is a desired number sequence, this number sequence can be set as an unlocked number sequence.
[0011]
After arbitrarily setting the unlocking number string, as shown in FIG. 15, if each dial bush 33 takes the retracted position again with respect to each dial, the inner peripheral gear portion 31c and the outer peripheral gear portion 33c The rotation position of each dial 31 with respect to each dial bush 33 is fixed by the engagement. As a result, the set unlock number string is stored.
[0012]
In this conventional example, as shown in FIGS. 14 and 15, the dial bush 33 is always urged in the forward direction as a whole, and is fitted onto the dial shaft 32 on the forward direction side. A first bush 134 is disposed. Therefore, when the unlocking number string set as described above is stored, the first bush 134 may be pressed in the direction of the dial bush 33.
[0013]
As shown in FIG. 17, the first bush 134 includes a flange portion 134 b that comes into contact with the dial bush 33 and a pair of tongue-shaped portions 134 a that extend in the axial direction. A shaft hole 134c for being fitted is formed through.
[0014]
As shown in FIGS. 13 to 15, the umbrella holding device 100 operates as a mechanism for pressing the first bush 134 by pressing an operation button 190 protruding from the upper portion of the body 110. 109 is provided. In addition, an operation mechanism 108 that restricts the movement of the shutter 102 in conjunction with the operation of the button mechanism 109 is further provided.
[0015]
In addition to the operation button 190, the button mechanism 109 includes an operation bar 191 disposed perpendicular to the axial direction of the dial shaft 32. The operation bar 191 is reciprocally movable so as to take up and down positions along a vertical groove 107 formed in the body 110 so as to extend in the vertical direction, and is always urged in the upward direction. ing. The operation bar 191 is provided with a second cam 193 that acts on the tongue 134 a of the first bush 134.
[0016]
As shown in FIG. 14, when the operation bar 191 is in the raised position, the second cam 193 comes into contact with the tip of the tongue-like portion 134 a of the first bush 134, and the dial bush 33 is in contact with the dial 31. When the operation bar 191 takes the lowered position as shown in FIG. 15, the tongue-like portion 134a of the first bush 134 is dialed by the linearly formed convex portion 193a. Each dial bush 33 is configured to take a retracted position with respect to the dial 31 by pressing in the direction 31.
[0017]
As shown in FIGS. 14 and 15, the operating mechanism 108 includes a link bar 181 a that protrudes from the side surface of the operation bar 191 and extends to the outside of the vertical wall 108 that forms the vertical groove 107, and FIGS. 18 and 19. As shown, the first link 182a is rotatably supported on the outside of the vertical wall 185, and the rotation is interlocked with the link bar 181a. The reciprocating horizontal movement is interlocked with the first link 182a. And a configured second link 182b.
[0018]
The vertical wall 185, the first link 182a, and the second link 182b are arranged in parallel to the flat surface 122a of the shutter 102 in a state where the shutter 102 closes the opening 111. As shown in FIG. 18, the first link 182a and the second link 182b are arranged so that the second link 182b does not contact the flat surface 122a of the shutter 102 when the operation bar 191 takes the raised position. As shown in FIG. 4, when the operation bar 191 takes the lowered position, the second link 182b is interlocked so as to come into surface contact with the flat surface 122a of the shutter 102.
[0019]
Further, the operation bar 191 is provided with a first cam 192 formed so as to restrict the movement of the operation mechanism 108 when the axial movement of the dial shaft 32 is disabled. .
[0020]
As shown in FIGS. 14 and 15, the first cam 192 contacts the tip of the dial shaft 32 both when the operation bar 191 takes the raised position and when the operation bar 191 takes the lowered position. When the operation bar 191 is in the intermediate position, the dial shaft 32 is formed in the retracted position by the convex portion 192a having a mountain shape. Therefore, when the dial shaft 32 cannot move from the forward movement position to the backward movement position, the operation bar 191 cannot rise from the lowering position toward the rising position.
[0021]
In such an umbrella holding device 100, the operation bar 191 is in the raised position when it is not in use. As a result, the second link 182b is not in contact with the flat surface 122a of the shutter 102 as shown in FIG. 18, and each dial bush 33 is in contact with each dial 31 as shown in FIG. The forward position is reached. Therefore, the shutter 102 can be rotated, the umbrella handle H can be received by the umbrella receiving portion 101, and an arbitrary unlocked number string can be set by rotating the dial 31. At this time, the recess 33d of each dial bush 33 is in the same phase as each projection 32b of the dial shaft 32, and the dial shaft 32 is movable in the backward direction.
[0022]
After setting the unlock number sequence, if the operation button 190 is operated so as to be pressed from above, the operation bar 191 takes the lowered position. At this time, as shown in FIG. 15, the tip of the dial shaft 32 is pressed by the convex portion 192a of the first cam 192 to temporarily take the retracted position, and then the tip thereof is the convex portion of the first cam 192. It moves out of 192a and takes the forward position again. At the same time, the tip of the first bush 134 is pressed by the convex portion 193 a of the second cam 193, and each dial bush 33 takes a retracted position with respect to each dial 31. Further, the second link 182b is in surface contact with the flat surface 122a of the shutter 102 as shown in FIG. Therefore, the inner peripheral gear portion 31c and the outer peripheral gear portion 33c are engaged, and the set unlock number sequence is stored. Further, the shutter 102 becomes non-rotatable and the umbrella handle H cannot be removed from the umbrella receiving portion 101.
[0023]
If each dial 31 is rotated in this state, that is, with the operation button 190 pressed (see FIG. 15), each dial bush 33 rotates with respect to the dial shaft 32, and at least one of the three dial bushes 33 is present. When the recesses 33d of the two dial bushes are out of phase with the protrusion 32b of the dial shaft 32, the movement of the dial shaft 32 is restricted. As a result, even when the operation button 190 is released and the operation bar 191 is urged upward by the coil spring 180, the tip of the dial shaft 32 cannot ride on the convex portion 192a of the first cam 192. The movement of the operation bar 191 is restricted in the lowered position. Therefore, since the second link 182b remains in surface contact with the flat surface 122a of the shutter 102, it is possible to form a locked state in which the state in which the shutter 102 cannot rotate is maintained.
[0024]
In order to set this in the unlocked state, if each dial 31 is rotated to form an unlocked number string, the operation bar 191 automatically moves so as to take the raised position by the urging force, and the second link 182b. When the surface contact state between the shutter 102 and the flat surface 122a of the shutter 102 is released, the shutter 102 can be rotated.
[0025]
Thus, in this conventional umbrella holding device 100, the button mechanism 109 and the operation mechanism 108 are interposed between the dial lock 103 and the shutter 102, so that one operation (pressing operation of the operation button 190) can be performed. The dial lock 103 can be stored in a state where the unlock number string can be stored, and at the same time, the movement of the shutter 102 can be restricted.
[0026]
[Problems to be solved by the invention]
However, the button mechanism 109 and the actuating mechanism 108 have a complicated configuration and a large number of parts, resulting in an increase in manufacturing cost. Further, in order to break the unlocking number string and enter the locked state, it is necessary to rotate the dial 31 while pressing the operation button 190, which makes operation difficult.
[0027]
The present invention has been conceived under the circumstances described above, and provides an umbrella holding device that can reduce the number of components and can be easily operated, and an umbrella stand using the same. That is the issue.
[0028]
DISCLOSURE OF THE INVENTION
  In order to solve the above problems, the present invention takes the following technical means.
  In other words, an umbrella holding device according to the present invention includes a body, an umbrella receiving portion that is open on the front surface of the body and is formed in a vertically penetrating manner so as to receive an umbrella handle, and an opening portion of the umbrella receiving portion. A shutter that slides in a horizontal direction so as to open and close and a dial lock for restricting the movement of the shutter are provided, and the dial lock cannot rotate and is orthogonal to the sliding direction of the shutter. Reciprocating movement is possible to take a forward position approaching the shutter and a backward position moving away from the shutter, and a plurality of protrusions are formed on the peripheral surface at predetermined intervals in the axial direction, and always urged in the forward direction. Dial shafts, a plurality of dial bushings fitted to the dial shafts corresponding to the number of protrusions, and fitted to each dial bush and rotated at a fixed position in the axial direction. Multiple and a dial that can be.
  Each of the dial bushes can take a forward position and a backward position with respect to the dial shaft, and is always urged in the forward direction as a whole, and has a recess that can be engaged with the protrusion. And when it is in the retracted position with respect to the dial shaft, it can rotate with respect to the dial shaft, whereas when it takes a predetermined rotational position with respect to the dial shaft, the concave portion and the protrusion are It can be engaged to take a forward position and cannot rotate.
  An inner peripheral gear portion is formed on the inner periphery of the dial, and an outer peripheral gear portion that can be engaged and disengaged in the axial direction with the inner peripheral gear portion is formed on the outer periphery of the dial bush. When the dial is in the forward position, the inner and outer gear portions are not engaged with each other, and the dial can rotate relative to the dial bush, while the dial bush is in relation to the dial. When in the retracted position, the inner peripheral gear portion and the outer peripheral gear portion are engaged with each other so that the dial cannot rotate relative to the dial bushing.
  On one side of the shutter, when the shutter is in the open position, both the dial shaft and the dial bush are engaged to assume the forward movement position so that an arbitrary unlocking number string can be set. When the shutter is in the closed position, when the shutter is in the closed position, only the dial shaft is engaged so that the unlocked number sequence set by storing the forward position is stored, and the shutter When taking an intermediate position between the open position and the closed position, a planar working surface is formed which allows both the dial shaft and the dial bush to take a retracted position.
[0030]
Here, the dial lock has a plurality of dials in which a plurality of numbers are written on the peripheral surface, and one of the plurality of numbers is indicated at a predetermined position for each dial. When this is done, the number of digits corresponding to the number of dials is formed by the instructed numerals, which includes the function of a general lock device. Further, the unlocking number string refers to a number string when the number of the number string is changed from the locked state where the movement of the shutter is restricted to the unlocked state where the shutter is released.
[0031]
  Invention of the present applicationaccording to, The shutter isMechanism to set unlock number sequenceAnd the locking mechanism is configured to directly regulate the movement of the shutter.Mechanism to set unlock number sequenceSince no other mechanism such as a button mechanism or an operating mechanism is interposed between the shutter and the shutter and between the locking mechanism and the shutter as in the conventional example, the number of parts can be reduced.
[0034]
In a preferred embodiment, the dial shaft has a distal end that is stepped to reduce a diameter of a shaft body having a predetermined outer diameter on the distal side with respect to the shutter. The plurality of dial bushes are always urged in the forward direction by a first coil spring fitted to the first shaft, and the plurality of dial bushes are fitted on the proximal side with respect to the shutter of the dial shaft. The first bush is sandwiched between a second bush that is fitted on the distal side with respect to the shutter, and the first bush cannot rotate within the body and has a forward position and a backward position on the dial shaft. The second bushing acts on a flange portion formed on the dial bushing side, and has an engaging groove on the inner periphery that can engage with the protrusion. 2 coil springs up The first bush is urged in the forward direction together with the dial bush, and the first recess is formed so that both the tip of the first bush and the tip of the dial shaft are engaged, and the second recess is Only the tip end of the dial shaft is engaged.
[0035]
In a preferred embodiment, the shutter has a knob portion formed so as to protrude from the other side surface facing the one side surface, and is manually operated by the knob portion.
[0036]
Further, in a preferred embodiment, the dial has a polygonal shape in plan view, and one number is written on each side surface.
[0038]
  Furthermore, the present inventionbyIn the umbrella holding device, since the shutter and the dial shaft are orthogonal to each other, the dial shaft does not apply a load to the shutter in the sliding direction when moving. Since the dial bush and the first bush reciprocate on the dial shaft, similarly to the dial shaft, no load is applied to the shutter in the sliding direction when moving. Therefore, the position of the shutter does not change unless it is manually slid. As a result, the operation on the umbrella holding device, that is, the rotation operation of the dial and the slide operation of the shutter can be performed independently, so that it is necessary to perform the rotation operation of the dial while pressing the operation button as in the conventional example. The umbrella holding device can be easily operated.
[0039]
  According to the present inventionThe umbrella holding device functions as follows.
[0040]
When the shutter is in the closed position, only the dial shaft is in the forward position. More specifically, the dial shaft takes a forward position with respect to the shutter, and the dial bushing takes a backward position with respect to the dial. At this time, the inner peripheral gear portion and the outer peripheral gear portion are engaged, and the dial bush can be rotated with respect to the dial shaft by rotating each dial. Here, when the recess of at least one dial bush among the plurality of dial bushes is not in the same phase with respect to the protrusion, the dial shaft cannot move from the forward position to the backward position. . Therefore, the shutter cannot take an intermediate position. That is, the shutter cannot slide and a locked state is formed. On the other hand, when the concave portions of all the dial bushes are in the same phase with respect to the respective protrusions, the dial shaft can be moved from the forward movement position to the backward movement position. That is, an unlocked state is formed. The number sequence at this time is an unlocked number sequence set in advance.
[0041]
When the shutter is in the open position, both the dial shaft and the dial bushing are in the forward position. More specifically, the dial shaft takes a forward position with respect to the shutter, and the dial bushing takes a forward position with respect to the dial. As a result, the protrusion and the recess are engaged, and the dial can rotate relative to the dial bush. Therefore, even when the dial is rotated, the state where the protrusion and the recess are engaged is maintained. As a result, if the displayed number string is a desired number string, it can be used as a new unlocked number string.
[0042]
After setting the unlocking number string, if the shutter is closed, each dial bushing takes the retracted position again with respect to each dial, so that the inner peripheral gear portion and the outer peripheral gear portion are engaged with each other. The rotational position with respect to the dial bushing is fixed. That is, the set unlock number string can be stored.
[0043]

[0051]
Further, the umbrella holding device A is provided with a shutter 2 capable of opening and closing the opening 11 and a dial lock 3 for restricting the movement of the shutter 2. The movement of the shutter 2 when the shutter 2 is in the closed position can be limited.
[0052]
The shutter 2 slides in the horizontal direction so as to open and close the opening portion 11. As shown in FIGS. 3 to 5, the body 10 has a linear shutter groove 12a having a shutter window 12b opened to the opening portion 11, and a concave shape disposed at a position facing the shutter window 12b. A shutter receiving portion 12c is formed. As shown in FIG. 3, the shutter 2 engages with the shutter groove 12a and is accommodated in the body 10 as a whole, thereby taking the open position in which the opening portion 11 is fully opened. Thereby, the handle H of the umbrella can be smoothly put in and out of the umbrella receiving portion 1. From this open position, as shown in FIG. 5, the shutter 2 moves along the shutter groove 12a, and then the tip protruding from the shutter window 12b engages in the shutter receiving portion 12c. As shown in FIG. 2, the open position 11b is fully closed. Thereby, the hook F of the umbrella cannot pass through the umbrella receiving portion 1, and it becomes impossible to remove the handle H of the umbrella from the receiving portion 1.
[0053]
Note that the shutter 2 includes a knob portion 21 formed so as to protrude outward from the side surface 2a, and can be easily reciprocated and moved manually.
[0054]
As shown in FIG. 2, the dial lock 3 has three dials 31 that can be manually rotated, and a plurality of numbers are written on the peripheral surface of each dial 31. More specifically, in the present embodiment, as shown in FIG. 7, each dial 31 has a regular decagon in plan view, and its ten side surfaces 31a.₁~ 31a_TenThe numbers from “0” to “9” are respectively described. On the other hand, as shown in FIG. 2, three rectangular window portions 30 are formed through the upper body 10 b, and each dial 31 protrudes partially from each window portion 30. Are arranged to be. Thereby, each dial 31 is rotated, and one of the numbers written on the peripheral surfaces of the three dials 31 is set to a predetermined position, so that a three-digit number string can be displayed. Of these number strings, the number string displayed when the movement of the shutter 2 is changed from the locked state to the unlocked state in which the movement is released is referred to as an unlocked number string.
[0055]
The dial lock 3 can be set to an arbitrary unlocked number sequence and an unlocked number setting mechanism for storing the set unlocked number sequence, and the unlocked number sequence can be stored by breaking the unlocked number sequence. And a locking mechanism to be formed. As shown in FIG. 3 to FIG. 5, the dial lock 3 includes a dial shaft 32 that is the center of rotation of the three dials 31, and between each dial 31 and the dial shaft 32. And three dial bushes 33 respectively interposed between them, and these members are configured so that the unlocking number setting mechanism and the locking mechanism function.
[0056]
Each of the dials 31 is configured to be rotatable at a fixed position in the axial direction. The dial shaft 32 is configured to be capable of reciprocating in the axial direction so as to take forward and backward positions with respect to the shutter 2. Each dial bush 33 is configured to be able to take a forward position and a backward position with respect to the dial shaft 32.
[0057]
The locking mechanism forms a locked state (FIGS. 4 and 12) by preventing the dial shaft 32 from moving from the forward movement position to the backward movement position with respect to the shutter 2. At this time, each dial bush 33 Is configured to be in a state (FIGS. 4 and 11) in which an unlocked state (FIG. 3) can be formed by rotating each dial 31 by taking the retracted position with respect to each dial 31. . Further, the unlocking number setting mechanism forms a setting state (FIG. 3) in which an arbitrary unlocking number string can be set when each dial bush 33 takes an advance position with respect to each dial 31. Thus, each dial bush 33 is configured to take a retracted position with respect to each dial 31, thereby forming a storage state (FIG. 4) in which the set unlock number sequence is stored.
[0058]
In the umbrella holding device A, the dial lock 3 is directly applied to the shutter 2 to be in the set state when the shutter 2 is in the open position and in the storage state when the shutter 2 is in the closed position. It is configured as follows. Further, when the shutter 2 is in the closed position, its movement (sliding movement) is directly regulated by the dial lock 3.
[0059]
That is, when the shutter 2 is in the open position, each dial bush 33 is in the forward position with respect to each dial, and when the shutter 2 is in the closed position, each dial bush 33 is in the retracted position with respect to each dial. And the dial shaft 32 takes a forward position with respect to the shutter 2, and the dial shaft 32 takes a backward position with respect to the shutter 2 when the shutter 2 takes an intermediate position between the forward position and the backward position. Has been.
[0060]
In the dial lock 3, the dial shaft 32 is always urged in the forward direction so that the dial shaft 32 and the dial bush 33 always interact with the shutter 2, and the dial bush 33 is always constantly moved as a whole. It is biased in the forward direction.
[0061]
Hereinafter, the configuration of the umbrella holding device A will be described in detail.
[0062]
As shown in FIGS. 7 and 8, each dial 31 has a shaft hole 31 d formed through the center thereof, and is fitted into each dial bush 33. On the other hand, as shown in FIG. 11, three dial grooves 14 having a groove width W equivalent to the thickness t of the dial 31 (see FIG. 8) are formed in the body 10. It is installed in each dial groove 14 so as not to move in the axial direction. In this way, each dial 31 can rotate at a fixed position in the axial direction as described above.

Each dial 31 is installed so that two engaging recesses 31e facing each other among the 10 engaging recesses 31e are sandwiched by the engaging protrusions 5a, and the rotation posture is set. Temporarily fixed. At this time, the side surface 31a is formed at the center of each window 30 of the body 10.₁~ 31a_TenOne of them is arranged so as to be parallel to the window portion 30. Thus, one of the numbers “0” to “9” is displayed on each window 30 so as to be easily read. When each dial 31 is operated to rotate, the pair of dial fixing springs 5 are elastically deformed in a direction away from each other, whereby the engagement between the engagement recess 31e and the engagement protrusion 5a is released. 31 becomes rotatable. Then, another number is displayed on each window portion 30 by the engagement convex portion 5a engaging with another engagement concave portion 31e again.
[0065]
As shown in FIG. 6, the dial shaft 32 has a substantially cylindrical shaft body 32 a, and three protrusions 32 b corresponding to the number of the dials 31 on the peripheral surface thereof.₁32b₂32b_ThreeAre formed at predetermined intervals in the axial direction. Each protrusion 32b₁32b₂32b_ThreeThe radial cross section has a predetermined uniform cross section, and the height from the peripheral surface of the shaft main body 32a is the same.
[0066]
As shown in FIGS. 3 to 5, the dial shaft 32 is arranged so as to be orthogonal to the sliding direction of the shutter 2 and is supported by the dial bush 33 and the dial 31, thereby, as described above. The shutter 2 can be reciprocated in the axial direction so as to take forward and backward positions.
[0067]
Further, as shown in FIG. 6, the dial shaft 32 is stepped so that a distal end 32c distal to the shutter 2 has a reduced diameter with respect to the shaft body 32a. As shown in FIGS. 3 to 5, a first coil spring 4a formed so that the distal end 32c can be inserted and the shaft body 32a cannot be inserted is fitted. In this manner, the dial shaft 32 is constantly urged in the forward direction with respect to the shutter 2 as described above.
[0068]
Further, the dial shaft 32 is not allowed to rotate within the body 10, and the protrusion 32b₁32b₂32b_ThreeThe rotational position around the dial shaft 32 is not changed. Specifically, in the present embodiment, the dial shaft 32 has the protrusion 32b in an engagement groove 34c (see FIG. 10) of a first bush 34, which will be described later._ThreeThe shaft cannot be rotated by engaging. Further, in order to make the dial shaft 32 unrotatable, as shown in FIG. 6, the distal end 32 c is formed in a rectangular column shape, and a second bearing portion 13 b having a rectangular cross section is provided in the body 10. 3 to 5, the dial shaft 32 is installed in the body 10 so that the distal end 32c is engaged with the second bearing portion 13b.
[0069]
As shown in FIG. 7, each of the dial bushes 33 is formed in a substantially cylindrical shape as a whole, and the protrusion 32 b of the dial shaft 32 is formed on the inner periphery thereof.₁32b₂32b_ThreeA recess 33d that can be engaged with is formed in a groove shape having a uniform cross section. Further, the dial bush 33 has an end portion on the proximal side with respect to the shutter 2 as an outer peripheral gear portion 33c that can be engaged with and disengaged from the inner peripheral gear portion 31c of the dial 31 in the axial direction.
[0070]
More specifically, each dial bush 33 includes a collar portion 33a formed at a distal end with respect to the shutter 2, and a dial bush main body 33b disposed between the collar portion 33a and the outer peripheral gear portion 33c. The outer diameters of the collar portion 33a and the dial bushing body 33b are equal to the inner diameter of the shaft hole 31d of the dial 31. The inner diameter of the outer peripheral gear portion 33c and the inner diameter of the dial bushing body 33b are equal to the shaft diameter of the shaft body 32a of the dial shaft 32, and the inner diameter (radius) of the collar portion 33a is from the center of the shaft body 32a. Projection 32b of dial shaft 32₁32b₂32b_ThreeIs equal to or slightly larger than the distance to the apex. The concave portion 33d of the dial bush 33 is formed from the outer peripheral gear portion 33c to the dial bush body 33b.
[0071]
Each of the dial bushes 33 is fitted onto the dial shaft 32 so as to be in contact with each other, so that the forward and backward positions can be taken with respect to the dial shaft 32 as described above.
[0072]
Each dial bush 33 is configured to be rotatable with respect to the dial shaft 32 when in the retracted position with respect to the dial shaft 32. Therefore, as shown in FIG. 11 and FIG.₁Is located in the collar portion 33a of the dial bush arranged in the center, and the protrusion 32b₂Is configured to be located in the collar portion 33 a of the dial bush located closest to the shutter 2.
[0073]
At this time, the outer peripheral gear portion 33 c of each dial bush 33 and the inner peripheral gear portion 31 c of each dial 31 are engaged, and each dial 31 is not rotatable relative to each dial bush 33. That is, each dial 31 rotates with respect to the dial shaft 32 together with each dial bush 33 in a state where the rotational position of each dial bush 33 with respect to the recess 33 d is fixed.
[0074]
Further, when each dial bush 33 takes a predetermined rotational position with respect to the dial shaft 32, more specifically, as shown in FIG. 11, the recesses 33 d of all the dial bushes 33 are formed by the protrusions 32 b of the dial shaft 32.₁32b₂32b_ThreeAnd the respective recesses 33d are respectively formed on the projections 32b of the dial shaft 32.₁32b₂32b_ThreeAs shown in FIG. 3, the forward movement position can be taken with respect to the dial shaft 32. At this time, each dial bush 33 takes an advance position with respect to each dial 31.
[0075]
When each dial bush 33 takes an advance position with respect to the dial shaft 32, each of the concave portions 33d and the protrusion 32b of the dial shaft 32 are provided.₁32b₂32b_ThreeThe rotation with respect to the dial shaft 32 becomes impossible. In this case, the outer peripheral gear portion 33 c of each dial bush 33 does not engage with the inner peripheral gear portion 31 c of each dial 31. Therefore, each dial 31 can rotate relative to each dial bush 33. Thereby, each dial 31 can change the rotation position of each dial bush 33 with respect to the recess 33d.
[0076]
Further, in the present embodiment, on the distal side of the dial bush 33 with respect to the shutter 2, as shown in FIGS. 3 to 5, the second bush 35 fitted to the dial shaft 32 and the second bush 35 act. A second coil spring 4b is disposed. As shown in FIG. 6, the second bush 35 includes a cylindrical cylindrical portion 35 a and a flange portion 35 b that acts on the dial bush 33. The inner diameter of the cylindrical portion 35a is defined to be larger than the outer diameter of the first coil spring 4a and smaller than the outer diameter of the collar portion 33a of the dial bush 33, and is equal to the outer diameter of the shaft main body 32a of the dial shaft 32. It is considered equivalent. The second coil spring 4b has an inner diameter that is about the outer diameter of the cylindrical portion 35a, and is fitted into the cylindrical portion 35a of the second bush to urge the second bush 35 toward the shutter 2. As a result, the dial bush 33 is always urged in the forward direction as a whole as described above.
[0077]
In the dial lock 3 having the above-described configuration, the dial 31, the dial shaft 32, and the dial bush 33 operate as follows, whereby the locking mechanism and the unlock number setting mechanism function.
[0078]
The locked state is formed by making the dial shaft 32 immovable as described above. More specifically, in the locked state, as shown in FIG. 4, the dial shaft 32 takes an advanced position, and as shown in FIG. 12, the recess 33 d of at least one of the three dial bushes 33. Is the corresponding protrusion 32b of the dial shaft 32.₁32b₂32b_ThreeFormed when not in phase. That is, all the protrusions 32b of the dial shaft 32₁, Protrusion 32b₂, Protrusion 32b_ThreeCannot engage with the recess 33 d of each dial bush 33, and the dial shaft 32 cannot enter the retracted position with respect to the shutter 2.
[0079]
At this time, as shown in FIG. 4, if each dial bush 33 is set in the retracted position with respect to each dial 31, each dial 31 cannot rotate with respect to each dial bush 33. The dial bush 33 can rotate with respect to the dial shaft 32. Accordingly, by rotating each dial 31, each dial bush 33 rotates with respect to the dial shaft 32, and the phase of each recess 33d changes.
[0080]
Here, as shown in FIG. 11, the concave portions 33d of all the dial bushings 33 are respectively formed on the protrusions 32b.₁32b₂32b_ThreeIf the phase is the same as that of the dial shaft 32, the dial shaft 32 can be in the retracted position, and an unlocked state is formed. At this time, the number sequence formed by the numbers displayed on each window 30 is the unlocked number sequence set in advance.
[0081]
From this state, as shown in FIG. 3, if each dial bush 33 is moved in the forward direction with respect to each dial 31, the concave portions 33 d of all the dial bushes 33 correspond to the corresponding protrusions 32 b.₁32b₂32b_ThreeEngage with. Thereby, each dial bush 33 cannot be rotated with respect to the dial shaft 32. At this time, since the outer peripheral gear portion 33 c of each dial bush 33 is disengaged from the inner peripheral gear portion 31 c of each dial 31, each dial 31 can be rotated relative to each dial bush 33. Here, if the number string displayed on the window 30 is a desired number string, this number string can be set as the unlocked number string. In this way, the setting state described above is formed.
[0082]
After setting the desired unlock number sequence, if each dial bush 33 is set to the retracted position again with respect to the dial 31, all the dials are engaged by the engagement between the inner peripheral gear portion 31c and the outer peripheral gear portion 33c. The recess 33d of the bush 33 is a protrusion 32b.₁32b₂32b_ThreeThe rotation positions of the dials 31 with respect to the dial bushes 33 are fixed. In this way, the storage state described above is formed.
[0083]
  In the umbrella holding device A, as described above, when the shutter 2 is in the open position, the dial bushes 33 move forward with respect to the dials 31 and when the shutter 2 takes the closed position, the dials The bush 33 takes the retracted position with respect to each dial 31, the dial shaft 32 takes the advanced position, and the shutter 2Open positionWhenClosed positionThe dial shaft 32 is configured to take the retracted position when the intermediate position is taken.
[0084]
Further, in this umbrella holding device A, when the shutter 2 takes the intermediate position, the phase of each dial 31 and each dial bush 33 is shifted to prevent the set unlock number sequence from changing. Each dial bush 33 is configured such that it cannot rotate relative to each dial 31, that is, takes a retracted position with respect to each dial 31.
[0085]
Specifically, the shutter 2 has a first recess 22 that allows both the dial shaft 32 and the dial bush 33 to take forward positions when the open position is set, and the dial shaft 32 when the closed position is set. A second recess 23 that allows only the forward movement position and an action surface 25 that allows the dial shaft 32 and the dial bush to move backward when taking the intermediate position are formed on the side face 2b on the dial lock 3 side. Has been. Further, in the umbrella holding device A, a first bush 34 fitted to the dial shaft 32 is provided between the dial bush 33 and the shutter 2 in order to facilitate the axial movement of the dial bush 2 by the shutter 2. Is arranged.
[0086]
As shown in FIG. 3, the first recess 22 is formed so that both the first bush 34 and the dial shaft 32 are engaged when the shutter 2 is in the open position. Further, the wall surface 22b between the bottom surface 22a and the working surface 25 of the first recess 22 can easily move the first bush 34 axially with respect to the dial shaft 32 when the shutter 2 is slid from the open position to the intermediate position. It is formed to be inclined at a predetermined angle with respect to the working surface 25 so that it can be moved.
[0087]
As shown in FIG. 4, the second recess 23 is formed so that only the dial shaft is engaged when the shutter 2 is in the closed position. Further, the wall surface 23b between the bottom surface 23a of the second recess 23 and the action surface 25 easily moves the dial shaft 32 in the axial direction with respect to the shutter 2 when the shutter 2 is slid from the closed position to the intermediate position. In order to be able to do so, it is inclined with respect to the working surface 25 at a predetermined angle.
[0088]
As shown in FIG. 5, the working surface 25 is formed to be planar between the first recess 22 and the second recess 23. The distance between the bottom surface 22a of the first recess 22 and the working surface 25 depends on the stroke when each dial bush 33 moves from the retracted position to the advanced position with respect to the dial 32, as shown in FIG. It is defined so that the engaged state between the gear portion 33c and the inner peripheral gear portion 31c can be released. The distance between the bottom surface 23a of the second recess 23 and the action surface 23a depends on the stroke when the dial shaft 32 moves from the retracted position to the advanced position.₁, 32b₂32b_ThreeAnd the recesses 33d of the dial bushes 33 are defined so as to be released.
[0089]
As shown in FIG. 10, the first bush 34 includes a generally cylindrical tip portion 34 a as a whole and a flange portion 34 b disposed on the distal side with respect to the shutter 2. The tip end portion 34a has an inner diameter equal to the outer diameter of the shaft body 32a, and the protrusion 32b is formed on the inner periphery thereof._ThreeAn engagement groove 34c that can be engaged is formed. The flange portion 34b has a rectangular shape in plan view. On the other hand, as shown in FIG. 3, a second bearing portion 13 a having a rectangular cross section in plan view is formed in the body 10. The first bush 34 has a flange portion 34b in contact with the outer peripheral gear portion 33c of the dial bush arranged on the most proximal side, and the engaging groove 34c has the protrusion 32b._Three(See FIG. 11) so as to be engaged in the second bearing portion 13a. The first bush 34 becomes incapable of axial movement in the second bearing portion 13a by the engagement of the flange portion 34b and the second bearing portion 13a, and the engaging groove 34c and the protrusion 32b_ThreeCan be reciprocally slidable on the dial shaft 32.
[0090]
In the present embodiment, the protrusion 32b with respect to the engagement groove 34c._ThreeAre formed so as to engage with each other, but this protrusion 32b_ThreeAnother second protrusion may be formed on the peripheral surface of the dial shaft 32 so that the second protrusion engages with the engaging groove 34c.
[0091]
Next, the operation of the umbrella holding device A will be described.
[0092]
When the umbrella holding device A is not used, that is, when the shutter 2 is in the open position, the first bush 34 engages with the first recess 22 as shown in FIG. Is urged by the second coil spring 4b to take the forward position with respect to the dial 31. At this time, the tip of the dial shaft 32 comes into contact with the bottom surface 22a of the first recess 22 to take the forward position, and the protrusion 32b₁32b₂32b_ThreeAre engaged with the recesses 33d of the dial bushes 33, respectively. Therefore, since each dial 31 can be rotated relative to each dial bush 33, an arbitrary unlocking number string can be set.
[0093]
Next, after the umbrella handle H is received in the umbrella receiving portion 1, as shown in FIG. 4, if the shutter 2 is manually slid to the closed position, only the dial shaft 32 is placed in the second recess 23. The engaged state is established, and the first bush 34 is moved in the backward direction. As a result, the outer peripheral gear portion 33c of each dial bush 33 is engaged with the inner peripheral gear portion 31c of each dial 31, so that the set unlock number sequence is stored.
[0094]
Next, as shown in FIG. 12, if each dial 31 is rotated to break the unlocking number string, the protrusion 32b₁, 32b₂, 32b_ThreeOf these, at least one projection is out of phase with the corresponding concave portion 33d of the dial bush 33, so that the dial shaft 32 cannot move in the backward direction. Therefore, the shutter 2 cannot be slid. As a result, the umbrella cannot be taken out from the umbrella holding device A.
[0095]
Next, when the umbrella is taken out again from the umbrella holding device A, all the protrusions 32b are formed as shown in FIG.₁, 32b₂, 32b_ThreeAnd the recesses 33d of all the dial bushings 33 are in the same phase, so that the dial shaft 32 can move in the backward direction.
[0096]
When the shutter 2 is manually slid in the opening direction, the dial shaft 32 moves in the backward direction along the wall surface 23b of the second recess 23 as shown in FIG. 2 The engagement with the recess 23 can be released. Thereby, the shutter 2 can be made into an open position. Therefore, the umbrella handle H can be taken out from the umbrella holding device A.
[0097]
Thus, in this umbrella holding device A, since the shutter 2 directly acts on the unlocking number setting mechanism and the locking mechanism acts directly on the shutter 2, as in the prior art, No button mechanism or operating mechanism is required. Therefore, the number of parts can be reduced.
[0098]
Further, in this umbrella holding device A, the locking mechanism and the unlock number setting mechanism that directly act on the shutter 2 are arranged so that the dial shaft 32 is orthogonal to the sliding direction of the shutter 2. Do not apply force in the sliding direction. Therefore, the position of the shutter 2 does not change unless it is manually slid. As a result, as described above, when the unlocked number string is broken and the locked state is formed, there is no need to rotate the dial while pressing the operation button as in the conventional case, and the locked state is achieved only by rotating the dial. Is easy to operate.
[0099]
As described above, according to the present invention, the number of components can be reduced and the operation can be easily performed.
[0100]
Of course, the scope of the present invention is not limited to the embodiment described above. For example, although the umbrella holding device A is provided with three dials 31, the number of dials 31 can be changed. In this case, the number of dial bushes 33 and the number of protrusions on the dial shaft 32 may be the same as the number of dials 31.
[0101]
Further, for example, the dial bush 33 is configured to receive the action from the shutter 2 and the second coil spring 4b via the first bush 34 and the second bush 35, but the dial bush 33 is configured to receive the shutter 2 and the second coil spring. You may comprise so that it may receive an effect | action directly from 4b.
[0102]
Further, the tip end 34a of the first bush 34 has a cylindrical shape as a whole. For example, the tip end 34a is formed like the tongue-like portion 134a of the first bush 134 in the conventional example. It is good also as a pair of tongue-shaped part formed so that it might extend in an axial direction along a surrounding surface.
