Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a rod structure according to the preamble of claim 1 and method of installing the same according to the preamble of claim 8, and in particular to a lifter rod structure and method of installing the same, utilized in bathing and sanitary sphere.

THE PRIOR ARTS

Presently on the market, the lifter rod is installed in the following approach. Firstly, a base seat is installed on a wall, then one end of the lifter rod is installed on the base seat; afterwards, another base seat is installed on the wall, then the other end of the lifter rod is installed on the other base seat, to finish installing the lifter rod. Such an approach of installation tends to be rather complicated, time consuming, and installation is liable to be not accurate and precise. In case large quantity of lifter rods are required to install, that could constitute quite a heavy load for the installation personnel.
Therefore, presently, the design of the lifter rod is not quite satisfactory, and it leaves much room for improvement.
From GB 2 404 186 A a package for a wall bracket is known with a template being comprised by the package and provided for easy installation of the wall bracket. Such wall brackets are used as towel racks, soap racks, ring hanger racks and so forth. The template comprises perforations at the position of the contact ends of the wall bracket and in particular at the position of mounting holes of back board plates to be mounted on a wall by means of screws and plastic rivets. So, the wall can be marked allowing for holes to be bored at the right positions and thus, for correctly installing the back board plates. The contact ends of the wall bracket are in turn arranged on the back board plates and fixed thereon also by means of screws.
From EP 1 892 339 A1 a lifter rod structure is known comprising a rod, two column heads, a movable shower seat and two back board plates ("locking members"). The back board plates are mounted on a wall by means of nails and nail plugs. The column heads consist each of an inner sleeve and an outer sleeve being movable with respect to each other such that the distance between the wall and the rod can be adjusted.
CH 658 586 A5 discloses a lifter rod structure comprising a rod, two column heads and a movable shower seat. The column heads are directly mounted on a wall by means of screws and screw anchors.
From DE 38 15 900 A1 a lifter rod structure is known comprising a rod, two column heads and a movable shower seat. The column heads are either directly mounted on a wall by means of screws or distance plates are arranged between the wall and at least one of the column heads. In case only one distance plate is used, different wall thicknesses due to tiles being put on the wall only up to a certain height can be leveled out. For allowing that a head column is arranged on a distance plate the former possesses a notch and the latter a tongue.
DE 696 12 942 T2 discloses a wall bracket to hold on for disabled persons, old persons or nursing personal assisting other persons. The wall bracket comprises a rod and two column heads. The column heads are directly mounted on a wall by means of an adhesive. The column heads can be provided with a suction cup so that the column heads can be fixed to the wall by a partial vacuum until the adhesive is cured completely.

(1) gluing a back side of a base seat 21 onto a wall;
(2) pressing a drill head of a drill onto a center of the base seat 21, to drill a hole on the wall;
(3) fixing the base seat 21 on the wall through using the inflatable tube 23 and the screw 22;
(4) placing one end of the paper tape 3 onto the base seat 21 through its positioning hole 31 (as shown in Fig. 8);
(5) placing the other base seat 21 through the other positioning hole 31 at the other end of the paper tape 3, then gluing the base seat 21 onto the wall;
(6) removing the paper tape 3, and repeating steps (2) to (3) once; and
(7) placing two column heads 13 of a lifter rod set 1 assembled in advance onto the two fixed base seat 21 respectively, to perform fixing and installation (as shown in Figs.10 to 11).

In the step (1) mentioned above, the back side of the base seat 21 can be provided with a double-sided tape; and during installation, the free side of the tape is torn away to facilitate easy installation.
In the step (2) mentioned above, the center of the base seat 21 can be provided with a through hole cut in advance, or the through hole can be drilled upon installation.
In the step (3) mentioned above, during installation, the inflatable tube 23 can be aligned with the central through hole 212 of the base seat 21, then the inflatable tube 23 is driven into central through hole 212 through using a tool. Afterwards, the screw 22 is aligned with the inflatable tube 23, and then a screw driver is used to drive the screw 22 tightly into the inflatable tube 23.
The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention.
