The present invention relates to a shield, more specifically, a rain shield having multiple porous configurations defined thereon as ventilators adapted for a window to achieve the benefit for ventilation and to avoid the permeation of rain.
A traditional tilt and slide window, as shown in
To achieve above objective, a rain shield which possesses feature of good ventilation and doesn't allow the permeation of water during a rainy day is consisted of a first face, and a second face disposed on an opposite side thereof, characterized in that a plurality of first pores are defined on said first face and a plurality of second pores are defined on said second face; each first pore is corresponding to a second pore and are connected by a slope passage.
Further, said first pore is connecting to an upper or higher end of the passage, and said passage is slanted downwardly to connect said second first pore at a lower end.
Said second pore has a curve rim.
Above-mentioned rain shield can also be adapted for a tilt slide window, which consists of a window frame and said rain shield is set freely therein for the sliding movement.
Moreover, a locking device is further included. Said locking device has a male and a female member, the male member has a hook provided freely therein, being able to move vertically. A resilient element is disposed in said male member and attached to an end of the hook. A detachable fixing member engages with said male member further to restrain the movement of the hook. Said female member has a groove for receiving said hook of the male member. Said male member is provided at a side of the rain shield approximating to the frame, and said female member is provided at the frame, corresponding to the location of the male member.
By installing the rain shield, the multiple angled passages can bring fresh air to the indoor, improving air circulation or ventilation, avoiding entry of the rain. Moreover, unlike the conventional screen window, which can be easily broken, the shield can be made of harden material to prevent damage from animal or human. With the additional locking device, it can also be served as a safety device to avoid children, elderly person or objects falling off from the window. The rain shield can also be installed onto a door of an automobile for the same purpose.
The preferred embodiments of the present invention are described in details hereinafter, according to the appended drawings.
Referring to
Said first pore (211) has a curve rim as circumference and is connecting to an upper or higher end of the passage (23), and said passage (23) is slanted downwardly to connect said second pore (221) at a lower end.
When using the rain shield (2), the second face (22) is facing indoor and the first face (21) is facing outdoor. Since pores (211) of the first face (21) are lower than pores (221) of the second faces (22), when said pores (211, 221) are connected by the passage (23), the fresh air from outside can be brought to the inside of the room but keeps the falling water, e.g. rain at outside, preventing it from wetting the furniture in the house. Even if the water enters the inside through the second pore (221) and the passage (23) by capillarity, the curve rim of the first pore (211) can lead the water to the passage (23) set under and guiding toward outside.
For the usage on a normal weather, said window may function equally as the conventional tilt and slide window. However, when it starts raining, the user can slide the rain shield (2) and leave the window opened.
For safety measure, a locking device (4) can be applied further to the window, locking the rain shield (2) when is closed.
As shown in
As shutting the rain shield (2), the hook (411) of the male member (41) engages the corresponding groove (421) on the female member (42). The resilient element (412) which is attached to the hook (411) can be a retracting spring, providing a force to retract the hook (411) to its original position and fixing the hook (411) and the groove (421).
The fixing member (43), as shown in the embodiment, can be a C-shape object, by using two extreme ends thereof against male member (41) and the hook (411) respectively, the fixing member (43) blocks the vertical movement of the hook (411) and avoiding the disengagement of the hook (411) from the groove (421).
In the second embodiment, by replacing the conventional screen window (13) with rain shield (2), the window can provide ventilation without worrying the interior of the room being wet on a rainy day, and with the installation of the lock (4) to gain additional safety measure to prevent any accident.
A third embodiment of the present invention is shown in
Referring to
The locking member (511) can be turned and engaged with the receiving member (52). The sliding member (513) is then inserted into the groove (512) and the stop (514) is lifted to fix the receiving member (513) in the groove (512), disabling the movability of the locking member (511) and fastening the rain shields (2).
By replacing the conventional glass with the rain shield (2), it provides a full-time ventilation to the building, reducing the usage of air conditioning device, and the locks (4) can fix the rain shields (2) to the frame (3), minimizing the risk of any accident.
Said two rain shields (2) can also be replaced by a single piece (not shown) and the installation locks (4) can be optional. The rain shield (2) can also be applied to other area where good ventilation or air circulation is required, e.g. stadium, gymnasium or recreation center.
Referring to
Since the inner side of the automobile is a confined space, driver usually turns on the air conditioning device to maintain the air circulation when car windows (61) are closed, but it consumes extra fuel, generating unnecessary waste. To reduce fuel consumption, some drivers may maintain the window (61) opened when stayed in a parked automobile, however, the risk of safety of the driver is increased. By adding said rain shield (2) to the car door body (6), driver can maintain the ventilation under a rainy day without using air conditioning device, reducing fuel consumption and further increase the safety of driver when stayed in a parked automobile.
