ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a sliding door, and more particularly to a sliding door having a retaining device for retaining the door panel in place.
2. Description of the Prior Art
Typical sliding doors (
FIGS. 5-7
) include a number of door panels
10
slidably coupled to an upper track
12
with wheels or rollers
11
and include a free end portion having a beam
13
secured to the door panels
10
. A retaining device
15
is secured to a supporting wall or door frame
80
, or may be secured to the end beam
13
of the other sliding door (FIG.
8
). The retaining device
15
and the end beam
13
each has one or more magnetic devices
16
,
17
engaged therein for attracting with each other and for securing the end beam
13
to the retaining device
15
. A handle
14
is attached to the end beam
13
for moving the door panels
10
and for moving the beam
13
toward and away from the retaining device
15
. However, the retaining device
15
and the beam
13
are required to be excavated with a number of holes for engaging the magnetic devices
16
,
17
into the holes of the retaining device
15
and the beam
13
respectively.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional sliding doors.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a sliding door having a retaining device for retaining the door panel in place.
In accordance with one aspect of the invention. there is provided a sliding door assembly comprising a a first sliding door device including a plurality of door panels slidably coupled to a track and including an end beam, and a retaining device including a channel for receiving the beam, and the retaining device including a pair of opposite resilient stops extended inward of the channel and extended toward each other and each having a free end portion, the channel of the retaining device including a size greater than that of the beam for receiving the beam in the channel, a distance between the free end portions of the resilient stops being smaller than that of the beam for allowing the resilient stops to engage with and to retain the beam within the retaining device.
The retaining device is secured to a supporting member. A handle is secured to the beam for moving the beam toward and away from the retaining device.
A second sliding door device is further provided and includes a plurality of door panels slidably coupled to the track and movable along the track, the second sliding door device includes a first end having a beam provided thereon, and means for securing the retaining device to the beam of the second sliding door device. The retaining device includes a recess formed therein and opposite to the channel of the retaining device for receiving the beam.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
