ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a frame, more particularly to a webbed frame for use in a piece of furniture.
2. Description of the Related Art
Referring to
FIGS. 1
,
2
A and
2
B, a conventional webbed frame for use in a piece of furniture, such as a bed, is shown to include a rectangular frame body
13
, a plurality of first and second straps
12
, a plurality of hooks
123
,
16
, and a plurality of strap adjuster units.
As illustrated, the first and second straps
12
are mounted on the frame body
13
, and extend in criss-cross manner to form a net
121
above the frame body
13
. Each of the first and second straps
12
has a first strap section
122
fastened to the frame body
13
via the hook
123
and a screw
133
, and a second strap section
124
fastened to the frame body
13
via the hook
16
and one of the strap adjuster units. Each of the strap adjuster units includes a threaded bolt
153
and a mounting plate
15
that is secured on the hook
16
, which is detachably mounted on the frame body
13
, and that has a lower portion
150
holding the second strap section
124
of each of the straps
12
which passes over a rear side of the mounting plate
15
. The threaded bolt
153
threadedly extends through the mounting plate
15
, and has an abutting end that abuts against the second strap section
124
of the strap
12
in such a manner that rotation of the bolt
153
relative to the mounting plate
15
results in pressing or non-pressing action on the second strap section
124
of the first and second straps
12
so as to change tension of the net
121
on the frame body
13
.
The conventional webbed frame is disadvantageous in that the mounting plate
15
tends to disconnect from the hook
16
due to a pulling force acting on the lower portion
150
via the second strap section
124
when the first or second strap
12
is pressed by the bolt
153
.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a webbed frame for furniture, the webbed frame having a specific structure such that the aforesaid disadvantage encountered during use of the conventional webbed frame can be avoided.
Accordingly, a webbed frame of the present invention is adapted to be used in a piece of furniture, and includes a frame body defining a frame space, a plurality of adjuster units, and a plurality of first and second straps which are mounted on the frame body and which extend in criss-cross manner to form a net that covers the frame space. Each of the first and second straps has two opposite end sections that are trained on and turned around the frame body and that have terminating ends disposed underneath the net. A plurality of spaced apart retainers are fixed on and along the length of the frame body, and extend into the frame space. Each of the adjuster units includes a connector and an adjusting bolt. The connector is mounted slidably on a respective one of the retainers and is connected to a respective one of the terminating ends of the first and second straps so that movement of the connector on the respective one of the retainers results in concurrent movement of the respective one of the terminating ends so as to tighten or loosen the first and second straps on the frame body and so as to adjust tension of the net. The adjusting bolt threadedly engages and extends through the connector, and has an abutting end that abuts against the frame body so that rotation of the adjusting bolt results in concurrent movement of the connector and the respective one of the terminating ends so as to permit adjustment of the tension of the net on the frame body.
