Description

  The present invention relates to a multipurpose device for a vehicle that shields sunlight or the like from a windshield of an automobile, for example.

  Various proposals have heretofore been made in order to prevent the temperature in the passenger compartment from rising due to direct sunlight when a passenger car or work vehicle is parked outdoors in the daytime. For example, Japanese Patent Application Laid-Open No. 9-123752 discloses an automobile window curtain for use in a parked automobile. Japanese Laid-Open Patent Publication No. 11-208267 discloses a windshield shielding mechanism for blocking light entering from the windshield of an automobile. Further, Japanese Utility Model Laid-Open No. 7-31426 discloses an accordion-shaped awning that can be expanded and contracted in the vertical direction at the top of the glass window to shield the sun rays and secure the driver's field of view. A sunshade is disclosed that shields direct sunlight that is radiated into a vehicle when the vehicle is stopped and suppresses temperature rise in the vehicle.

  On the other hand, in the case of conventional sunshades for preventing a rise in the temperature inside the vehicle (the one in which a blur of blue or the like is inserted into a part of the windshield) and curtains are troublesome to mount and remove, for example, JP 2000 JP-A-198351 discloses a configuration in which a roll curtain is retractable and retracted inside an interior material provided in a vehicle, and the pulled roll curtain is fixed to a hook. The device which prevents the insertion of sunlight by covering the whole window of vehicles is indicated.

  Usually, the sun visor in the vehicle compartment is attached to a support member provided on the ceiling of the vehicle, but its attachment position (height from the driving seat) is set based on the average height of the driver. Yes. Therefore, depending on the height of the driver, there is an inconvenience that the light directly enters the eyes without being blocked by the sun visor. Therefore, the driver can cope with such an inconvenient situation by manually changing the height and angle of the sun visor and simultaneously raising the driving seat. However, adjusting the angle and position of the sun visor in accordance with traveling conditions during driving is not only troublesome but also not preferable from the viewpoint of safe driving. In addition, since the sun visor is located close to the driver's head, there are some drivers who feel that the sun visor itself is sparse and disturbs driving.

  The sunshade device according to the above-mentioned utility model No. 7-31426 is intended to obtain a sun visor and a sunshade for shielding while keeping the sunshade freely movable up and down from the upper end to the lower end of the glass window. Therefore, there is no adhesion between the glass window and the awning. Similarly, the sunshade device disclosed in Japanese Patent Application Laid-Open No. 2006-51925 also discloses an example of use as a sun visor, but the configuration is complicated and the blind seat and the front window do not come into close contact with each other. As a result, a gap or space is created between the windshield and the sunshade, and indoor air that moves as the vehicle travels or air from the air conditioner flows into the space, causing the sunshade to flutter, causing noise, or driving. There is a problem of hindrance. In addition, as a result of lack of adhesion with the windshield, it is possible to look inside the vehicle through a gap or the like. For example, there is a problem that it is difficult to ensure privacy in the vehicle during parking.

  The present invention has been made in view of the above-described problems. The object of the present invention is to realize a total or partial light shielding of the windshield with a simple configuration, and to suppress an increase in the temperature of the vehicle interior and externally. It is to provide a multipurpose device for a vehicle that can blindfold the interior of the vehicle.

As a means for achieving this object and solving the above-mentioned problems, for example, the following configuration is provided. That is, the multipurpose device for a vehicle according to the present invention is provided along a roll curtain disposed at the top of a vehicle window and capable of being drawn out and wound up inside the ceiling of the vehicle compartment, and each of the vertical end portions of the window. The roll curtain is composed of a light-shielding and flexible sheet-like member that covers the window across the vertical ends of the window and moves up and down while closely contacting the glass surface. By making it possible, while exhibiting a temperature rise prevention function and a blindfold function of the passenger compartment when the entire window is covered, it can be used as a sun visor when stopped at an arbitrary position.
For example, the guide portion has a groove portion, and the side end portion of the roll curtain is slidable while being fitted in the groove portion. In addition, for example, the groove is provided with a protrusion that extends to apply a pressing force to a side end portion of the roll curtain. Furthermore, for example, a long plate member having a predetermined weight extending in the horizontal direction is disposed at the lowermost end of the roll curtain. Further, the window is a front window, and a central guide portion of the roll curtain, which is integrated with a rearview mirror (back mirror), is disposed substantially at the upper center of the front window. It is characterized in that the close contact of the roll curtain with the front window is assisted.
For example, a solar power generation module is arranged on the surface of the roll curtain, and a configuration capable of storing electric energy obtained by the solar power generation module is provided. In addition, for example, the roll curtain is divided into two parts, a driver seat side and a passenger seat side.

  According to the multipurpose device for a vehicle of the present invention, it effectively prevents the driver from being dazzled by direct sunlight, etc. inserted from the vehicle window, and also exhibits a blindfold function in the vehicle, and also increases the temperature inside the vehicle even when parking in the hot sun. Can be suppressed.

  Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows a state when the multipurpose device for a vehicle according to the present embodiment is attached to a vehicle such as a private car, and FIG. 2 shows a cross-sectional structure of the attachment. The multipurpose device for a vehicle according to the present embodiment provides a roll curtain 3 that can cover the entire surface of the windshield 2 of the vehicle 1. A closed space between the ceiling lining 8 and the main body 6 of the roll curtain 3 wound in a cylindrical shape is arranged in the storage 5. And it is the structure which can raise / lower the roll curtain 3 to an up-down direction, making it closely_contact | adhere along the glass surface of the windshield 2. FIG.

  Here, as the roll curtain 3, a roll-up roll curtain that is widely used is used, but the vertical length of the windshield of the vehicle is usually much shorter than the height of a window of a house or the like. Therefore, in the case of the multipurpose device for vehicles according to the present embodiment, the length of the curtain to be used can be shortened. As a result, the main body 6 of the curtain roll can also have a small diameter, so that it can be easily incorporated into the curtain storage part 5, which is a space of the ceiling part of the vehicle, which is limited as a space. Further, even after installation, there is no inconvenience in appearance and uncomfortable feeling that the portion protrudes from the roof lining 8.

  When the light is shielded by the roll curtain 3, the operator pulls the roll curtain 3 downward in a manner that resists a winding mechanism (not shown) provided in the main body 6 as necessary, and pulls the roll curtain 3 at a desired position. Stop. Thereby, the whole or part of the windshield 2 can be covered with the roll curtain 3, and not only complete light shielding but also use as a sun visor is possible. Further, when releasing the light shielding state, for example, the roll curtain 3 in a stopped state is slightly pulled downward to operate the winding mechanism to wind up the curtain. The roll curtain 3 can be stopped at a desired position by stopping the operation of the winding mechanism by pulling downward to stop the roll curtain 3 from rising during winding.

  Curtain guides 7a and 7b that run vertically along the edge of the glass are disposed at the left and right ends of the windshield 2 on the vehicle compartment side. Furthermore, a curtain guide 7c having a length required when the roll curtain 3 is used as a sun visor is disposed at the center upper portion of the windshield 2 and also on the back surface of the rearview mirror 21, for example. The tip portion T of the curtain guide 7c is rounded to prevent the curtain from being caught. In the example shown in FIG. 2, the curtain guide 7 c and the rearview mirror 21 are integrated, and the curtain guide 7 c also serves as a support column for the rearview mirror 21. By doing so, the curtain guide 7c does not interfere with the driver's field of view.

  FIG. 3A schematically shows a state in which the roll curtain 3 is pulled down so as to cover the entire windshield 2, and FIG. 3B is a view taken along the line AA in FIG. 3A. FIG. As shown in FIG. 3 (a), the bottom end of the roll curtain 3 is a long plate-like member whose lateral length is slightly longer than the width of the curtain and whose vertical length is several centimeters. A certain thin iron plate 4 is arranged in a horizontal direction so as to be wrapped with a curtain. The curtain guides 7a and 7b are provided with grooves 10a and 10b that run continuously in the longitudinal direction.

As shown in FIG. 3A, the width of the windshield of the vehicle may be wider at the lower side width W ₂ than at the upper side width W ₁ . Therefore, in the vehicular multipurpose device according to the present embodiment, when the roll curtain 3 is lowered to the lowest position, the end portions on both sides of the curtain are in the grooves 10a and 10b as the curtain guides 7a and 7b move upward. In order to fit deeper. For example, on the upper side of the guide, the side edge of the curtain fits in the grooves 10a and 10b by about 1 cm. On the other hand, it is set as the structure which can accommodate the edge parts 4a and 4b of the thin iron plate 4 in the groove | channels 10a and 10b in the lower part side of the curtain guides 7a and 7b. By doing in this way, even when the entire windshield 2 is covered with a curtain, it is possible to cope with the dimensional difference between the upper side and the lower side of the windshield, so that the roll curtain 3 does not come off and the curtain guides 7a and 7b There is no gap between the roll curtain 3 and the roll curtain 3.

  Protrusions 15a and 15b extending inward are provided in the grooves 10a and 10b, and when the roll curtain 3 moves up and down in the vertical direction, the side end portions of the curtains have these protrusions 15a and 15b. Slid in the grooves 10a and 10b while receiving a pressing force. By providing such a protrusion, it is possible to prevent the curtain from being detached from the curtain guide and to maintain the sealed state between the curtain side end and the guide. There is no wind blowing.

  The roll curtain 3 has a light shielding property and flexibility, and a sheet-like member that can be wound into a cylindrical shape, for example, a film made of polyester resin or the like is used as a base material. When the roll curtain 3 is pulled downward to be positioned on the front surface (vehicle compartment side) of the windshield 2, the left and right ends of the roll curtain 3 move while being accommodated in the grooves 10 of the curtain guides 7a and 7b as described above. Since the curtain guide 7c acts as a guide for the central portion of the roll curtain 3, the roll curtain 3 is brought into close contact with the curved surface of the windshield 2 as shown in FIG. Such a close contact state is maintained even when the roll curtain 3 is raised and lowered and stopped.

  In addition, it can be set as the curtain which has a light-shielding function and a temperature-rise prevention function by performing aluminum vapor deposition on one surface of a film base material, or apply | coating a coating-type heat insulating material. The thin iron plate 4 disposed at the lowermost end of the roll curtain 3 has an appropriate weight to function as a weight of the curtain and has the same flexibility as the curtain. It deforms along the curved surface of the glass 2 and adheres to the glass. Further, in order to smoothly raise and lower the roll curtain 3, a U-shaped handle 9 that can be gripped is attached to the center of the thin steel plate 4, as shown in FIG.

  FIG. 5 is a view showing a vertical cross-sectional configuration when the roll curtain 3 is pulled down to the lowermost part of the windshield 2 and the entire windshield 2 is covered with the roll curtain 3. As shown in FIG. 5, an inverted L-shaped hook 30 is arranged almost at the center of the upper surface of the dashboard 25 of the vehicle 1, and the curtain handle 9 is hooked when the roll curtain 3 is lowered to the lowest position. By being hooked on 30, the entire windshield 2 is blocked (light-shielded) by the roll curtain 3 so as to be reliably maintained. As can be seen from FIG. 5, the roll curtain 3 pulled down to the lowermost part of the windshield 2 performs a light shielding function in a state of being in close contact with the glass surface of the windshield 2.

  Thus, in the multipurpose device for a vehicle according to the present embodiment, a roll curtain of a wrapping method based on a sheet having light shielding properties and flexibility is attached to the top of the windshield of the vehicle along the interior, The curtain can be moved up and down along the windshield. When the pulled out curtain is stopped at a desired position, the windshield on the upper side from that position is covered with a curtain from end to end without any gap. For example, a driver of a vehicle such as a passenger car or work vehicle can use the curtain as a sun visor to block sunlight, etc. by stopping the roll curtain at the position of his / her eyes, from the front window of the vehicle, etc. It is possible to prevent the driver from being dazzled by blocking sunlight and other vehicle lights. In particular, since the light can be shielded only by raising and lowering the curtain, the driver can use the curtain as a sun visor without adjusting the height of the driving seat, regardless of the height of the driver.

  Further, by using a roll-type roll curtain as the light-shielding curtain, the main body can be reduced in size and can be accommodated in a narrow space, and the take-up mechanism facilitates accommodation of the curtain in the ceiling portion of the vehicle. For this reason, it is possible to easily release the light shielding state completely or partially. Furthermore, by adopting a general roll-in type roll curtain, the roll curtain can be attached to the ceiling portion of an existing vehicle by simple construction.

  In addition, when using the roll curtain as a sun visor, any area on the top of the windshield can be shielded from end to end in the horizontal direction. It is possible to prevent it completely. Further, since the light can be shielded from the edge of the windshield, it is not necessary to adjust the angle of the sun visor each time in the driving state where the positional relationship between the vehicle and the sun is constantly changing. In addition, since the sun visor function can be realized by slightly moving the roll-up type roll curtain in the vertical direction, the fine adjustment thereof is easy, and there is no troublesome operation especially during driving of the vehicle.

  On the other hand, by lowering the roll curtain to the lowermost part of the windshield, the entire windshield can be covered with the roll curtain in close contact with the windshield. Therefore, for example, even when the vehicle is parked under hot weather, direct sunlight radiated into the vehicle can be shielded by a roll curtain to suppress an increase in the temperature inside the vehicle, and it can also be used for blinding the interior of the vehicle and protecting privacy.

  In addition, the roll curtain material is not only light-shielding but also flexible, and the left and right ends of the windshield are provided with slidable grooves that fit into the left and right ends of the curtain. Further, by arranging the curtain guide extending in the vertical direction and the curtain guide at the center of the windshield, the windshield and the roll curtain are brought into close contact with each other at the time of light shielding, and an unnecessary gap is not formed between them. Therefore, the curtain can be raised and lowered or stopped in close contact with the curved surface of the glass on the inner side of the windshield (vehicle compartment side). For example, when using the curtain as a sun visor, the window was opened to run Sometimes the roll curtain does not flutter or fluctuate due to wind entering the car or air rising along the windshield while the air conditioner is operating.

Modified example

  The present invention is not limited to the embodiment described above, and can be modified as described below without departing from the spirit of the invention. In the above-described example, the curtain roll is manually raised and lowered while using the existing roll curtain winding mechanism. For example, a small motor is arranged in a closed space of the vehicle ceiling, and the motor By interlocking with the curtain winding mechanism, an electric shading curtain that can be raised and lowered by a simple switch operation provided separately may be used. Furthermore, for example, an optical sensor that constantly monitors the direction and horizontal angle (elevation angle) of sunlight that is inserted from the windshield of the vehicle into an appropriate position of the vehicle is arranged, and the detection result and the position (height of the driver's eyes) ) By sending a control signal based on the information to the drive motor of the roll curtain, a configuration may be provided in which the roll curtain can be raised and lowered appropriately so that sunlight does not enter the driver's eyes directly.

  By adopting such a configuration, it is not necessary to adjust the angle of the sun visor according to the incident sunlight, which has conventionally been based on manpower, and it is comfortable and comfortable without being bothered by the incident light from the constantly changing sun while the vehicle is running. Can perform safe driving. In particular, in the present modification, the sun visor function can be realized only by controlling the raising or lowering of the roll curtain, so that the apparatus configuration for that purpose becomes very simple. In addition, when using the roll curtain of the above electric control systems as a sun visor, if a curtain falls to the lowest part of a windshield during driving | running | working, it will lead to a driving accident etc. and is dangerous. Therefore, a safety device may be added that controls so that the curtain does not fall below a predetermined position during traveling.

  Further, in view of recent energy saving, non-pollution, enhancement of environmental protection measures, etc., the light shielding curtain may have a power generation function. Specifically, with the configuration shown in FIG. 6, a film-type photovoltaic power generation sheet 51 in which a solar cell (solar power generation) module 53 is arranged on the surface thereof and which can be rolled up is used as a curtain. For example, when the solar power generation sheet 51 is pulled down to be used as a light-shielding curtain, or when the curtain is lowered for the purpose of charging a car battery, sunlight is applied to the curtain and power generation is performed by the solar cell module 53. Electric energy suitable for the module area and conversion efficiency can be obtained. And the obtained electrical energy is mounted in the vehicle etc. beforehand, or is stored in the storage battery 55 installed separately.

  By providing such a power generation configuration, the storage battery 55 can be charged not only during parking but also during traveling, and the electrical energy can be consumed by a load 57 including various lamps, electromagnetic components, and the like as necessary. As a result, it is possible to provide an energy-saving multipurpose device for a vehicle that has both a light shielding function and a power generation function.

  On the other hand, in the embodiment described above, the entire windshield of the vehicle is covered with a single roll curtain. For example, as shown in FIG. 7, the curtain on the driver's seat and the passenger's seat (passenger) side are provided. It is good also as a structure divided into 2 to the curtain. The configuration shown in FIG. 7 is a configuration suitable for, for example, a large vehicle such as a truck or a bus, and is provided between the ceiling portion R on the windshield 2 and the roof lining 8 on the driver seat side and the passenger seat side. Roll curtains 3a and 3b wound in a cylindrical shape are disposed in the curtain storage portions 5a and 5b, which are closed spaces. Curtain guides 7a and 7b are provided at both left and right ends of the windshield 2 on the passenger compartment side, and a curtain guide 7d having a thickness that does not hinder the driver's view is provided at the center.

  FIG. 8 shows a cross-sectional configuration when FIG. 7 is viewed in the direction of arrow BB. In FIG. 8, the curtain guides 7a and 7b have a structure having grooves that run continuously in the longitudinal direction as in the above-described embodiment, but the curtain guide 7d is symmetrical in the longitudinal direction. Are provided with two grooves 20a and 20b running continuously. A roll curtain 3a on the driver's seat side is arranged between the curtain guides 7a and 7d so as to be movable up and down along the glass surface of the windshield 2. Similarly, a roll curtain 3b on the passenger seat side is arranged between the curtain guides 7b and 7d so as to be movable up and down along the glass surface of the windshield 2.

  By dividing the roll curtain into two in this way, in a large vehicle or the like, light can be shielded individually on the driver's seat side and on the passenger seat side, and it can also be used as a sun visor by appropriately adjusting the pull-down position of the curtain. is there. Further, the entire surface of the windshield 2 can be covered by pulling down both the roll curtains 3a and 3b to the lowest position and hooking them on the hooks 30a and 30b. At this time, although the curtain guide 7d disposed in the central portion of the windshield 2 has the structure shown in FIG. 8, there is no gap between the roll curtains 3a and 3b without causing any trouble in a practical large vehicle or the like. Since it does not occur, complete shading, blinding, and prevention of a rise in the passenger compartment temperature can be realized.

  Furthermore, although the roll curtain which can cover the windshield of a vehicle was illustrated in embodiment mentioned above, the installation place of a roll curtain is not limited to a windshield side, Between the ceiling part of a vehicle and roof lining. If a predetermined space can be secured, the present invention can be applied to other vehicle windows such as a rear window and a side window.
