Description

  The present invention relates to an in-vehicle umbrella stand for suitably storing an umbrella in an automobile. In particular, it can be moved to any location on the floor of an automobile, can easily organize umbrellas of various lengths, and is stable when the car is running or in contact with the person on board In addition, the present invention relates to an in-vehicle umbrella stand including a telescopic shaft with a stopper that can prevent droplets from splashing from a wet umbrella and preventing the umbrella from opening.

  Patent Document 1 discloses an umbrella stand having a structure for storing umbrellas of various lengths. The umbrella stand disclosed in Patent Document 1 includes a tray body and a support column that is erected at the center of the tray body. The support for the umbrella stand is configured by connecting three pipes, a base pipe, an adjustment pipe, and a main body pipe. A connecting member is provided at the upper end of the base tube, and the length of the support column can be adjusted to at least three stages by fitting the ball portion of the pin end of the connecting member with the through hole of the adjusting tube. it can. The umbrella stand of patent document 1 can be accommodated without falling down umbrellas of various lengths by adjusting the length of the column in three stages.

  However, in recent years, umbrellas of various lengths have been distributed from short umbrellas for infants to long umbrellas for sports, and these various umbrellas have been adjusted by the three-stage length adjustment disclosed in Patent Document 1. It has become difficult to store securely. Moreover, since the umbrella stand of patent document 1 fits the hole of a connection member and an adjustment pipe when fixing the length of a support | pillar, when changing the length of a support | pillar next, the connection member is attached to an adjustment pipe | tube. It had to be removed from the hole and it was very difficult to adjust the height quickly.

  Furthermore, although the technique for attaching the weight to the saucer is disclosed in the umbrella stand of Patent Document 1, the attachment position and weight of the weight are not optimized for in-vehicle use. When placed, it was completely unknown how much load and impact it would cause to fall over. In addition to this, the top of the umbrella stand receiving body of Patent Document 1 has an open top surface, and when this is used by placing it in a car, water accumulated in the receiving body due to vibrations and impacts during traveling is stored. There was a possibility that the interior of the car and the shoes and feet of passengers would get wet.

  Patent Document 2 discloses an umbrella stand having a substantially inverted conical umbrella support hole for storing the tip of the umbrella, and a brick placed on the umbrella stand body as a weight. However, since the umbrella stand of Patent Document 2 supports only the tip of the umbrella in which the umbrella support hole is accommodated, when the umbrella is accommodated, the umbrella is in an extremely unstable state, and the interior of the automobile When used in, only the umbrella could fall out. Further, when the umbrella stand of Patent Document 2 is used in an automobile, there is a high possibility that the wet cloth is touched by people or the interior unless the umbrella is bundled with a name band. For this reason, when storing an umbrella, it was necessary to bundle it with a name band every time, and it took much time to store the umbrella.

  Furthermore, the umbrella stand of Patent Document 2 is configured such that the drops dropped from the umbrella are absorbed by the bricks, and the drops are dried over time. For this reason, after placing the umbrella stand of Patent Document 2 in the car and storing the wet umbrella, not only inside the umbrella stand but also the entire inside of the car will be in a high humidity state for a long time, causing discomfort in the car. In addition to bringing about this, there was a problem that mold was likely to occur.

Patent Document 3 discloses an in-vehicle umbrella stand in which an umbrella stand pipe is disposed obliquely on a storage base, and a stopper is attached thereto. The umbrella stand of Patent Document 3 discloses specifications suitable for stably storing umbrellas of various lengths. However, since the umbrella is housed in this umbrella stand so as to protrude obliquely, there is a risk of drops falling from the umbrella cloth protruding from the stopper, and there is a risk that the person on board will drop the umbrella by catching it. was there.

(Example 1) Hereinafter, the vehicle-mounted umbrella stand of this invention is demonstrated in detail, referring drawings. FIG. 1 is a perspective view of an in-car umbrella stand 1 of this embodiment. FIG. 2 is a perspective view of a state in which the shaft portion of the vehicle-mounted umbrella stand 1 of the present embodiment is contracted and housed inside. The in-vehicle umbrella stand 1 in this embodiment is provided with an umbrella storage base 2, a shaft portion 4, an umbrella stand pipe 6, a stopper 8, and a handle 10.

  The umbrella storage base 2 in this embodiment is formed by molding ABS resin so that the bottom surface has a diameter of 25 cm, the top surface has a diameter of 20 cm, the height from the bottom surface to the top surface is 17 cm, and the side surface is substantially hemispherical. Is formed. A rubber slipper (not shown) is attached to the entire bottom surface. A through hole 12 through which the shaft portion 4 passes is provided at the center of the upper surface of the umbrella storage base 2. A pair of through holes 14 for inserting a pair of umbrella stand pipes 6 are provided on the left and right sides of the through holes 12.

  The through hole 14 is formed in a circular shape having a diameter of 4 cm. The pair of through holes 14 are arranged so as to form a left and right pair with the through hole 12 therebetween, and the center of the through hole 14 is at a distance of 6 cm from the center of the upper surface of the umbrella storage base 2. The horizontal distance from an arbitrary location on the peripheral edge of the bottom surface of the umbrella storage base 2 to the edge of the through hole 14 is 4.5 cm or more. A cylindrical support portion 16 having a height of 4 cm for supporting the shaft portion 4 is molded at the peripheral portion of the through hole 14.

  The pair of umbrella stand pipes 6 accommodated in the through holes 14 includes a conical main body 24 having an upper end diameter of 3.5 cm and a depth of 20 cm, and a disc-shaped edge formed at the upper end of the main body portion. A portion 26 is provided. When the umbrella stand pipe 6 is accommodated in the through hole 14 of the umbrella storage base 2, the support portion 16 provided around the through hole 14 supports the edge portion 26, so that the umbrella stand pipe 6 penetrates. It is prevented from falling into the hole 14. The umbrella stand pipe 6 can be easily removed from the through hole 14 and the support portion 16, and can be quickly dried by throwing away the water accumulated therein.

  The shaft portion 4 is configured by concentrically arranging three stainless steel tubes having different diameters. That is, the first inner cylinder 20 is arranged inside the outer cylinder 18, and the second inner cylinder 22 is arranged further inside the first inner cylinder 20.

  The inner diameter of the lower end portion of the outer cylinder 18 is formed smaller than the outer diameter of the first inner cylinder 20, and the lower end portion of the outer cylinder 18 is always in pressure contact with the outer periphery of the first inner cylinder 20. On the outer periphery of the upper end portion of the first inner cylinder 20, a projection (not shown) that presses against the inner cylinder of the outer cylinder 18 is provided, and this projection is always pressed against the inner cylinder of the outer cylinder 18. Similarly, the lower end portion of the first inner cylinder 20 is always in pressure contact with the outer periphery of the second inner cylinder 22, and a not-shown protruding portion of the upper end portion of the second inner cylinder 22 is always in the first inner cylinder 22. The cylinder 20 is pressed.

  The shaft portion 4 is disposed perpendicular to the bottom surface of the umbrella storage base 2, and the lower end portion of the second inner cylinder 22 is fixed to the bottom surface of the umbrella storage base 2. By holding and lifting the spherical handle 10 provided at the upper end of the shaft portion 4, the first inner cylinder 20 and the second inner cylinder 22 are sequentially pulled out from the outer cylinder 18. Since the three cylinders are always in pressure contact with each other, the shaft portion 4 can expand and contract in a stepless manner as a whole, and can extend to a desired arbitrary height and maintain an upright state.

  In the extended state, the shaft portion 4 has a configuration in which the outer cylinder 18 located at the upper part is the thickest, and the first inner cylinder 20 and the second inner cylinder 22 are sequentially arranged at the lower part and become gradually thinner. Yes. For this reason, even when the water | moisture content of an umbrella falls to the axial part 4, water does not approach into the space inside the axial part 4. FIG. Further, no moisture remains at the joint between the outer cylinder 18 and the first inner cylinder 20 or the joint between the first inner cylinder 20 and the second inner cylinder 22, and the entire shaft portion can be easily dried. With this configuration, the shaft portion 4 is free from mold and bacteria, and a sanitary umbrella stand shaft portion is provided. Moreover, there is no fear that the shaft part 4 will rust or discolor, it is excellent in durability, and a beautiful appearance is maintained for a long time.

  A pair of stoppers 8 are fixed to the outer cylinder 18 of the shaft portion 4. The stopper 8 is bonded to the outer cylinder 18 so that the center thereof is located on the extension line of the central axis of each upper end opening of the umbrella stand pipe 6. The stopper 8 is made of ABS resin and is formed in an annular shape having an inner diameter of 6 cm.

    As shown in FIG. 2, when the first inner cylinder 20 and the second inner cylinder 22 are accommodated in the outer cylinder 18 and the entire shaft portion 4 is contracted, the lower surfaces of the pair of left and right stoppers 8. And the upper surface of the edge portion 26 of the pipe 6 for umbrella stand are in contact with each other. The lower part of the shaft part 4 is accommodated in the umbrella storage base 2. The umbrella stand 1 in a state in which the shaft portion 4 is contracted includes a substantially hemispherical umbrella storage base 2, a pair of cylindrical support portions 16, a pair of annular stoppers 8, and a spherical handle 10. In the unlikely event that the in-car umbrella stand 1 of the present invention falls due to an unexpected impact, the person on board may hit it and be injured, There is no risk of damaging the interior.

  Gypsum is poured into the bottom of the umbrella storage base 2 from the through hole 14 and hardened to form a weight 11. The amount of gypsum poured is adjusted so that the weight of the in-car umbrella stand 1 is 2 kg. The plaster in the present embodiment is poured into the bottom surface of the umbrella storage base 2 with a thickness of 2 cm. The position of the center of gravity of the umbrella stand in the height direction is about 10% from the bottom surface in a state where the shaft portion 4 is contracted.

  The on-vehicle umbrella stand 1 of the present embodiment having the above-described configuration stores the umbrella in both or either of the umbrella stand pipes 6 with the shaft portion 4 contracted, and then the shaft portion 4 is moved. By extending, the stopper 8 fixed to the outer cylinder 18 of the shaft portion 4 is pulled up along the outside of the umbrella. FIG. 3 shows a state in which the in-car umbrella stand 1 accommodates two umbrellas 31 having the same length. Since the inner diameter of the upper end of the umbrella stand pipe 6 is 3.5 cm and the depth is 20 cm, the umbrella 31 is accommodated along the umbrella stand pipe 6 substantially vertically.

  Since the inner diameter of the stopper 8 is 6 cm, sufficient space is secured between the umbrella 31 and the stopper 8 even when the umbrella 31 that is not bundled with the name band is accommodated and the shaft portion 4 is extended. . The shaft portion 4 can be smoothly extended along the umbrella 31 stored vertically, and the stopper 8 can be quickly pulled up to support the umbrella 31. When the inner diameter of the stopper 8 is smaller than 4 cm, it is very difficult to extend the shaft portion 4 when a large umbrella is stored. Further, when the umbrella 31 is taken out, the shaft portion 4 can be smoothly contracted if the inner diameter of the stopper is 6 cm.

  As a result of studies conducted using various umbrellas having a length of the main bone of 40 cm to 85 cm, it was found that the position where the stopper 8 is stopped is most preferably the same position as the name band of the umbrella 31. When the stopper 8 is disposed at this position, there is a minimum possibility that the umbrella 31 will be accidentally opened without being tied with a name band, and the umbrella cloth will come into contact with a car seat or a passenger and get wet. Can be effectively prevented.

  On the other hand, it is clear that if the stopper 8 can be arranged closer to the hand than the center of the umbrella, the umbrella can be stably stored. As a result of these various studies, it has been determined that the shaft portion 4 needs to be extended so that the position of the stopper 8 is at least 30 cm or higher from the edge portion 26 of the umbrella stand pipe 6. . That is, if the shaft portion 4 can be extended so that the position of the stopper 8 is 30 cm from the edge portion 26, even a very large umbrella having a length of the main bone of 85 cm is held at the center of the umbrella. It has been identified that it is possible to stably store umbrellas of various lengths including such very large umbrellas. Further, when the shaft portion 4 can be extended longer than that, even a very large umbrella can be held at almost the same position as the name band, and a more preferable storage state can be realized.

  If two umbrellas with different lengths are to be stored, both umbrellas can be stably stored by disposing the stopper 8 at a position closer to the hand than the center of the longer umbrella. It became clear as a result of examination that it was possible.

  Below, the stability evaluation result of the in-car umbrella stand 1 of the present embodiment will be described in detail. The stability was evaluated by two methods. First, in order to evaluate the stability of the in-car umbrella stand 1 during travel, the in-car umbrella stand 1 is applied to a vehicle traveling on a road with a sharp curve (minimum curve radius R = 100 m) at 40 km / h. The behavior was observed. Hereinafter, this stability evaluation is also referred to as running stability evaluation. In addition, in order to evaluate the stability when a person riding in an automobile comes into contact with the in-car umbrella stand 1, an impact load is applied to the grip of the umbrella standing on the in-vehicle umbrella stand 1. The behavior of the umbrella stand 1 and the entire umbrella was observed. Hereinafter, this stability evaluation is also referred to as contact stability evaluation. In contact stability evaluation, the impact load is applied to the umbrella grip by hanging a pendulum with a length of 50 cm on the umbrella, attaching a 1 kg weight to the tip of the pendulum, lifting the pendulum horizontally, and then lifting the weight. The evaluation was performed by adopting a method of allowing it to fall freely and collide with an umbrella grip.

  For the stability evaluation, three types of umbrellas were used: a child umbrella with a parent bone of 40 cm and a weight of 180 g, a gentleman / woman umbrella with a parent bone of 60 cm and a weight of 400 g, and a sports umbrella with a parent bone of 80 cm and a weight of 700 g. Then, after storing one of these three types of umbrellas in one umbrella stand pipe 6, the shaft portion 4 is extended so that the stopper 8 reaches the position of the name band of the umbrella. FIG. 6 shows the results of the running stability evaluation and the contact stability evaluation in the state pulled up. The in-car umbrella stand 1 of the present example was able to stably store all the umbrellas.

  Further, FIG. 7 shows the results of carrying out the stability evaluation during traveling and the contact stability evaluation by storing two umbrellas in the in-car umbrella stand 1 of the present embodiment. This evaluation was performed when two sports umbrellas were stored, and when a sports umbrella was stored on one side and a children's umbrella was stored on the other side. The in-car umbrella stand 1 of this embodiment is very stable even when two umbrellas having different lengths or two umbrellas longer than usual are stored, and safely stores the umbrella when the vehicle is running. It was clarified as a result of this experiment that it was possible.

  For comparison, five running stability evaluations and contact stability evaluations were performed for comparison with respect to five types of umbrella stand tools having different configurations from the in-vehicle umbrella stand tool 1 of this example. The configuration of these comparative umbrella stands will be described below. The comparative umbrella stand has the same configuration as that of the in-vehicle umbrella stand 1 except for a particularly specified configuration.

  In the umbrella stand of Comparative Example 1, the position of the weight disposed inside the umbrella storage base 2 is high. The position in the height direction of the center of gravity of the umbrella stand of Comparative Example 1 is about 30% from the bottom surface with the shaft portion 4 being contracted.

  In the umbrella stand of Comparative Example 2, the length of the umbrella stand pipe is as short as 15 cm.

  In the umbrella stand of Comparative Example 3, the inner diameter of the umbrella stopper is as large as 10 cm.

  The umbrella stand of Comparative Example 4 is configured such that the bottom surface of the umbrella storage base is not provided with a slip stopper, and the resin on the bottom surface comes into contact with the floor surface of the automobile.

  In the umbrella stand of Comparative Example 5, the umbrella storage base is cylindrical. The umbrella storage base of Comparative Example 5 is molded such that the bottom and top diameters are 18 cm.

  About the umbrella stand of these comparative examples 1-5, the result of having performed stability evaluation at the time of driving | running | working and contact stability evaluation is shown in FIG.6 and FIG.7. In particular, the umbrella stand having a high center of gravity of Comparative Example 1 and the umbrella stand having a bottom diameter of 18 cm of Comparative Example 5 are overturned during the evaluation, and are clearly inappropriate as an in-vehicle umbrella stand. It became. Moreover, the umbrella stand having a short pipe for the umbrella stand of Comparative Example 2, the umbrella stand having a large inner diameter of the stopper of Comparative Example 3, and the umbrella stand having no slip of Comparative Example 4 are The movement was confirmed and the stability was found to be insufficient. In addition, the “risk of falling” in this evaluation result was confirmed by visual observation that the umbrella stand and the umbrella in it vibrated or lifted during the evaluation, and there was a possibility of falling. State.

  As a result of all the stability evaluations, all of the comparative example umbrella stand tools are likely to fall over, or actually move or fall over under the condition that this embodiment stably holds the umbrella. It became clear to do. These unstable behaviors were particularly noticeable when a long sports umbrella was stored.

  The on-vehicle umbrella stand 1 of this embodiment is optimized for the bottom area and the center of gravity of the umbrella stand 2, the length of the umbrella stand pipe 6, and the diameter of the stopper 8. It has become clear that the synergistic effect is very stable and can safely store one or two umbrellas of various lengths. If even one of these characteristics is not optimized, the stability, which is an essential requirement for an in-car umbrella stand, deteriorates, and in the worst case, it falls over while running with the umbrella stored It was confirmed that

  In addition, it was possible to further improve the stability as an on-vehicle umbrella stand by further increasing the bottom area of the umbrella storage base 2. However, it has become clear as a result of various studies that the diameter of the bottom surface of the umbrella storage base 2 larger than 30 cm is not preferable because the position of the umbrella storage base 2 in a small automobile is very limited.

  Similarly, it was possible to improve the stability by increasing the weight of the weight 11 and increasing the weight of the entire in-car umbrella stand. However, it has become clear as a result of examination that if the total weight exceeds 2 kg, it is difficult to move in the vehicle, which is not preferable as an in-car umbrella stand.

  Similarly, by increasing the length of the umbrella stand pipe 6, it is possible to prevent vibration of the stored umbrella and improve the stability. However, the longer umbrella stand pipe 6 is difficult to dry at the bottom where it is closed and does not leak water, and it has been confirmed that mold has been generated over a long period of use. The result is clear.

(Example 2) Sectional drawing of the vehicle-mounted umbrella stand 41 of a present Example is shown in FIG. Those having the same configurations as those of the first embodiment are given the same reference numerals and redundant description is omitted. The height from the bottom surface to the top surface of the umbrella storage base 42 of the in-vehicle umbrella stand 41 of this embodiment is 25 cm. The inside of the umbrella storage base 42 is divided into an upper part 46 and a lower part 48 by a partition plate 44. The inside of the lower part 48 is formed in a substantially cylindrical shape having a height of 7 cm. The lower end portion of the second inner cylinder 22 of the shaft portion 4 is fixed to the center portion of the upper surface of the partition plate 44.

  An illuminating means 50 including an automatic lighting circuit and an automatic extending / contracting means 52 of the shaft portion 4 are disposed in the lower part 48 of the umbrella storage base 42. The illumination means 50 and the automatic expansion / contraction means 52 are both driven by a battery. The umbrella storage base 42 in this embodiment is formed so that a part of the resin plate on the bottom surface can be removed, and the battery can be replaced.

  The automatic extension / contraction means 52 of the shaft portion 4 in this embodiment includes a drive cord 54 that passes through the partition plate 44 and is inserted into the shaft portion 4 and connected to the upper end of the outer cylinder 18 of the shaft portion. And a retractable drive gear 56, a reversible motor 58 that rotates the drive gear, and a control means (not shown) that controls the amount and direction of rotation of the reversible motor 58. The automatic expansion / contraction means 52 of the shaft portion 4 is electrically connected to a switch (not shown) that inputs an expansion / contraction operation of the shaft portion 4 provided on the side surface of the umbrella storage base 42.

  The switch is an operator that can be moved up and down with a finger. While the switch is pressed upward, a signal for extending the shaft portion 4 is input to the control means and the switch is pressed downward. Inputs a signal for shortening the shaft portion to the control means.

  The control means includes a microcomputer and a motor driver for the reversible motor 58. When a signal from the switch is input, the control means controls the forward / reverse operation and stop of the reversible motor 58 by controlling the motor driver. A drive gear 56 is connected to the reversible motor 58, and the drive gear 56 rotates in conjunction with the rotation of the reversible motor 58.

  A rack is formed on one surface of the drive cord 54, and this rack meshes with the teeth of the drive gear 56. When the shaft portion 4 is extended, the drive cord 54 is fed into the shaft portion 4 according to the rotation of the drive gear 56. On the contrary, when shortening the shaft portion 4, the shaft portion 4 is pulled back from the shaft portion 4 and temporarily wound around the winding means 60. When the drive code 54 is sent and retracted, the outer cylinder 18 of the shaft portion 4 to which the drive code 54 is fixed also moves in accordance with the movement of the tip of the drive code 54. As a result, the shaft portion 4 can be automatically expanded or contracted by operating the switch.

  A window (not shown) is provided by a transparent acrylic plate on the side surface of the lower portion 48 of the umbrella storage base 42, and an illumination unit 50 including an automatic lighting circuit is fixed along the window.

  The automatic lighting circuit in the present embodiment is a daylight switch configured using a photoelectric cell whose resistance value changes depending on brightness. Since the resistance value of the daylight switch decreases when the periphery of the photoelectric cell becomes dark, it is possible to supply the current from the battery power source to turn on the illumination. On the contrary, since the resistance becomes high when the periphery of the photoelectric cell becomes bright, it is possible to turn off the illumination by stopping the supply of current from the battery power source.

  When the illumination of the illumination means 50 is turned on, the surroundings can be illuminated through the window of the umbrella storage base 42. A person on board can check the position of the on-vehicle umbrella stand 41 and the umbrella stored therein by using the illumination means 50. In addition, since the switch 62 for automatically extending and retracting the shaft portion 4 can be confirmed, the umbrella can be taken in and out more easily and reliably even in a dark car. Furthermore, it is possible to reduce in advance the risk of contacting an umbrella stand or umbrella in a dark car and defeating them.
