ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a fitting, more particularly to a fitting adapted for holding spacedly a support member, such as a transverse rod, a sheet plate, or a holding ring, on an upright wall.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional fitting
1
is shown to include a positioning plate
10
with two holes
100
for passage of two screw fasteners
13
to fix on an upright wall
2
(see FIG.
2
), and a cover
11
which has a major surface wall
115
with a rectangular central hole
110
and three protrusions
111
disposed thereon, and a surrounding wall
116
that extends from a periphery of the major surface wall
115
and that has a through hole
113
. The positioning plate
10
engages the cover
11
among the protrusions
111
. One of the protrusions
111
has a screw hole
112
to align with the through hole
113
such that a screw fastener
114
can pass through the through hole
113
and the screw hole
112
to anchor on the positioning plate
10
and fasten the cover
11
on the latter. A holding member
12
has a protrusion
120
at a proximate end thereof to be inserted into the central hole
110
. The protrusion
120
has a screw hole
121
such that a screw fastener
122
is inserted into the screw hole
121
so as to fasten the holding member
12
on the major surface wall
115
of the cover
11
. The holding member
12
has a holding portion in the form of ring
123
for holding a support member of a disk
23
.
In assembly, the two screw fasteners
13
are first inserted threadedly into two screw fixtures
22
in two predetermined holes
21
in the upright wall
2
so as to fasten the positioning plate
10
on the wall
2
. Then, the support member
12
is secured on the cover
11
by the screw fastener
122
. Finally, the cover
11
is fastener on the positioning plate
10
by the screw fastener
114
.
Referring to
FIG. 3
, another conventional fitting
3
is shown to differ from the above fitting
1
in that the holding portion
32
is in the form of an elongated shaft which extends transverse to the upright wall
2
. An elongated retaining groove
320
is formed in and extends along the shaft. As such, when two fittings
3
are mounted on the upright wall
2
, two side edges of a support member in the form of a sheet plate
33
can be held within the retaining grooves
320
.
The conventional fittings
1
,
2
require many screw fasteners during assembly, thereby resulting in inconvenience. Moreover, as shown in
FIG. 3
, since there is a relatively large clearance
20
formed between the sheet plate
33
and the upright wall
2
due to the surrounding wall of the cover
31
, there is a tendency for the objects placed on the sheet plate
33
to fall therefrom.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a fitting which is can be conveniently assembled on an upright wall.
According to this invention, a fitting includes a stem extending in an axial direction and having a threaded surface adapted to be screwed into an upright wall. An annular head portion is connected to the stem, and has an abutting surface wall proximate to the stem and extending in a transverse direction relative to the axial direction for abutting against the upright wall when the stem is fixed in the upright wall. A cylindrical anchored member extends from the head portion in the axial direction away from the stem, and has a distal end distal to the abutting surface wall. A holding member includes an anchoring portion which is elongated in the axial direction to be sleeved on and to cover the anchored member, and a holding portion which is formed integrally with the anchoring portion for holding a support member. A fastening member is disposed to fix the anchoring portion relative to the anchored member by tightening along a radial direction relative to the axial direction. Thus, the fitting is fastener on the upright wall only by screwing the stem into the upright wall, thereby facilitating assembly of the fitting.
