Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shielding device, and more particularly to a shielding device or a sun visor for shielding the space between the vehicle and the door of the vehicle, when the vehicle door is opened.

2. Description of the Prior Art

Typically, while opening the vehicle doors or the doors of the buildings, a widely opened space will be formed between the door and the vehicle or the building. These problems particularly trouble or bother the vehicle drivers or passengers or various people, during the raining days, while opening the door of the vehicle or the building.

Particularly, while opening the door of the vehicle, the vehicle drivers and/or the passengers have to prepare one or more umbrella devices with them and have to open the umbrella devices right after the door of the vehicle has been opened.

The vehicle drivers and/or the passengers may still have a good chance to be wetted by the rain right after the door of the vehicle has been opened.

U.S. Pat. No. 6,213,137 to Wang discloses an umbrella automatically openable and extendible toward and above the widely opened space located between the door and the vehicle or the building, for shielding the space between the door and the vehicle or the building. However, the umbrella also may not be completely or fully shield or cover the widely opened space located between the door and the vehicle or the building. In addition, a complicated configuration is required for opening the umbrella. Furthermore, the vehicle drivers and/or the passengers may still have a good chance to be shut by the other people from the upper portions of the buildings.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional door opening problems of the vehicles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. [0032] 1-8, a shielding device in accordance with the present invention is provided for attaching or securing onto the door panel and for covering or shielding the widely opened space located between the door and the vehicle or the building, particularly while opening the door of the vehicle or the building, or while the vehicle drivers or the passengers are getting off the vehicle or while the persons are going out of the housing buildings.
The shielding device includes a pair of [0033] seats 4, 5 spaced away from each other and secured onto an object, such as the roof of the vehicle 7 (FIG. 1), or the wall 8 of the housing or building (FIG. 9), with fasteners 50 or locks or the like. The seats 4, 5 each includes a cavity 41, 51 formed therein and preferably having a non-circular cross section. A shaft 2 includes two ends 22, 23 engaged in the cavities 41, 51 of the seats 4, 5 and secured to the seats 4, 5 with fasteners 42, 52. It is also preferable that the ends 22, 23 of the shaft 2 include a non-circular cross section for engaging with the corresponding non-circular cross sectional cavities 41, 51 of the seats 4, 5 and for preventing the shaft 2 from rotating relative to the seats 4, 5.
The [0034] shaft 2 includes a peripheral bulge 21 extended radially outward from the middle portion thereof, and includes a hole 211 formed in the shaft and located beside the bulge 21, and includes two apertures 241, 251 formed in the end portions for receiving a stop pin 24, 25 therein. A spring 3, such as a coil spring includes one end portion 30 engaged onto the peripheral bulge 21 with such as a force-fitting engagement, and an end member 31 engaged and secured into the hole 211 of the shaft 21, and includes the other end member 32.
A roller or a [0035] spool 1 includes a bore 15 formed therein for receiving the shaft 2 and for rotatably securing the spool 1 onto the shaft 2, and includes a recess 16 formed in one end thereof for receiving one or more bearings 17 therein which may be secured onto the spool 1 with fasteners 170 and rotated in concert with the spool 1. The stop pins 24, 25 are engaged with the ends of the spool 1 for limiting the rotational movement of the spool 1 relative to the shaft 2 and for preventing the spool 1 from moving along the shaft 2.
The [0036] spool 1 or the bearing 17 includes an orifice 171 formed therein for receiving the other end member 32 of the spring 3, such that the spool 1 may wind up the spring 3 when the spool 1 is rotated relative to the shaft 2, and the spring 3 may then apply a spring biasing force to recover the spool 1 when the spool 1 is released. The one end portion 30 of the spring 3 is forced fitted onto the peripheral bulge 21 of the shaft 2, such that the force of or against the spring 3 may be partially released or dissipated by the peripheral bulge 21 of the shaft 2.
The [0037] spool 1 preferably includes a hollow structure having a peripheral chamber 10 formed therein and having one or more reinforcing stays or partitions 14 formed or provided therein for reinforcing the spool 1, and includes a substantially frustum-shaped configuration having one end 101 of a smaller outer diameter, and the other end 103 of a greater outer diameter (FIGS. 4-6), and includes one or more peripheral ribs 13 formed around the outer peripheral portion thereof for further reinforcing the spool 1.
The [0038] spool 1 includes a longitudinal passage 191 formed therein and parallel to the bore 15 thereof and communicating with the recess 16 of the spool 1 and having a blind or enclosed end 192, for receiving a rod 19 therein, and includes a slit 18 formed radially through about one half (½) of the spool 1 and communicating with the longitudinal passage 191 of the spool 1, for receiving one side or one edge of a cover or a shield 6. For example, as shown in FIG. 8, the shield 6 includes a longitudinal sleeve 62 formed in the one edge thereof and having an open end 621 for receiving the rod 19 and an enclosed end 622 for preventing the rod 19 from being disengaged from the sleeve 62 of the shield 6.
As best shown in FIGS. [0039] 4-7, the rod 19 and the sleeve 62 of the shield 6 may be engaged into the longitudinal passage 191 of the spool 1 before the bearing 17 is secured into the recess 16 of the spool 1, such that the bearing 17 may stably retain the rod 19 and the sleeve 62 of the shield 6 within the longitudinal passage 191 of the spool 1. The shield 6 includes a substantially sector-shaped configuration for allowing the shield 6 to be suitably wound around the spool 1 (FIG. 3) or unwound from the spool 1 (FIGS. 1, 2, 7, 9), when the spool 1 is rotated relative to the shaft 2.
The other side or [0040] edge 60 of the shield 6 may be detachably secured onto the door panel 71 of the vehicle 7 (FIG. 1), or onto the door panel 81 (FIGS. 9, 10) of the housing or building, with such as the hooks, the locks, the latches, the catches, or with the ears 61 that has a hook and loop device provided thereon which may be engaged with the corresponding hook and loop device provided on the door panel 71, 81, for allowing the other edge 60 of the shield 6 to be detachably secured onto the door panels 71, 81. The shield 6 may be made of cloth materials, plastic materials, or even bulletproof materials for acting as a sun visor, or a rain shield, or a shield for resisting bullets.
The [0041] spool 1 preferably includes a peripheral bead 11 extended radially outward from the one end 101 of the spool 1, and a peripheral stop 12 provided or formed or extended radially outward from the other end 103 of the spool 1 for limiting or retaining the shield 6 around the spool 1 and for preventing the shield 6 from being disengaged from the spool 1. A peripheral groove 121 is preferably formed and provided beside the peripheral stop 12 of the spool 1, for receiving the outer peripheral portion 69 of the shield 6 and for further positioning the shield 6 relative to the spool 1.
In operation, as shown in FIGS. 1 and 9, when the [0042] door panel 71, 81 is rotated and opened outward of the object, such as the vehicle 7 or the housing or wall 8, the shield 6 may be pulled outward or unwound from the spool 1, and may thus cover or block or shield the widely opened space formed between the door panel 71, 81 and the vehicle 7 or the wall 8 of the building. The shield 6 may thus be used or acted as a sun visor for shielding the sun shine, or a rain shield for preventing the users from being wetted by the rain, or a shield for resisting bullets.
It is to be noted that the [0043] seats 4, 5 may also be attached or secured onto the door panel 71, 81, and the other edge 60 of the shield 6 may be secured onto the object or the vehicle 7 or the wall 8, such that the shield 6 may also be opened to cover or block or shield the widely opened space formed between the door panel 71, 81 and the vehicle 7 or the wall 8 of the building when the door panel 71, 81 is opened relative to the object or vehicle 7 or wall 8.
Accordingly, the shielding device in accordance with the present invention may be provided for shielding the space between the vehicle and the door of the vehicle, when the vehicle door is opened, and for preventing the vehicle drivers or passengers from being wetted by rain while opening the vehicle door, or for using as a bulletproof device while the vehicle door is opened. The shield may be automatically opened to shield the space between the building and the door of the building, while the door of the building is opened. [0044]
