ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a baby seat and more particularly, to a hook-on type baby seat which is adapted to be used for gripped objects with various thicknesses. Such a hook-on type baby seat has an elevation adjusting and locking function and can be operated both in safety and in ease.
2. Description of the Related Art
FIG. 6
shows a conventional hook-on type baby seat
1
which comprises a seat portion
2
and a back portion
3
coupled to two forwardly projecting anchor members
4
and
5
. The anchor members
4
and
5
are adapted to overlie a table
8
. The conventional hook-on type baby seat
1
also comprises a grip means having a pair of free ends
6
and
7
below the anchor members
4
and
5
for gripping a bottom surface of the table
8
. The free ends
6
and
7
of the grip means are supported for movement toward and away from the elevation of the anchor members
4
and
5
. A latch means
9
extends between the grip means and the back portion of the baby seat
1
for latching the free ends
6
and
7
of the grip means in one of a plurality of positions.
However, the conventional hook-on type baby seat
1
cannot be securely hooked on the table. This is because that simply by the coordination between the free ends
6
and
7
of the grip means and the anchor members
4
and
5
, the resultant force generated therebetween is not sufficient to securely hold on the table due to a single-point contact. Therefore, the baby seat
1
is easily separate from the table by simply pulling the baby seat
1
in the horizontal direction.
In addition, since the conventional hook-on type baby seat does not have an elevation-adjusting function, the baby seat will be slanted in some angle. Consequently, the baby seat itself cannot be appropriately adjusted in accordance with the thickness of the table.
To overcome the defects of the conventional hook-on type baby seat described above, the present invention provides an implemented hook-on type baby seat which is simple and labor-saving in operation, comfortable and convenient in use and pleasant to the eyes. In addition, such a hook-on type baby seat has the following advantages, for example, it is convenient in carry and portability due to the compact retracting size and functions of elevation adjustment and safe locking can be achieved.
SUMMARY OF THE INVENTION
An object of the present application is to provide a hook-on type baby seat which makes a further implementation with reference to the defects of the conventional hook-on type baby seat in order to produce a safer and more convenient hook-on type baby seat.
The present invention provides a hook-on type baby seat primarily comprising a main body portion and a seat portion, in which the main body portion comprises a U-shaped arm assembly for supporting the baby seat on an upper surface of a gripped object; a pair of longitudinal arm members and one end of each of the longitudinal arm members is soldered to the U-shaped arm assembly; a pair of gripping arm members for gripping or releasing the gripped object in which one end of each of the gripping arm members is formed to become a gripping end bent upwardly, and the other end thereof is formed to become a C-shaped member for attaching to the corresponding longitudinal arm member; and a pair of elevation controlling and adjusting members combined with the pair of longitudinal arm members and gripping arm members for allowing the pair of gripping arm members to be upwardly and downwardly movable in the elevation direction of the longitudinal arm member so as to adjust and lock an elevation position of the pair of gripping arm members, and the seat portion comprises a seat cushion and a back portion hanged on the U-shaped arm member by sewing, in which a safety belt is provided in the inner side of the seat portion for fastening a baby.
The present invention provides a hook-on type baby seat in which the U-shaped arm assembly substantially comprises a U-shaped arm member, a pair of straight arm members, and a pair of positioning flexible members.
The present invention provides a hook-on type baby seat in which each of said pairs of elevation controlling and adjusting members comprises an elevation adjusting and locking portion, a release-or-grip control portion, a right cover and a left cover, and each of said elevation adjusting and locking portion comprises an adjusting button, a first spring, a locking button, a second spring, a stop strip and a joint block, and each of said release-or-grip control portion comprises a handle bar, a C-shaped movable component, a casing and a third spring. Each of said handle bar is further provided with a rubber pad, and a force is applied to said handle bar by the third spring so that the baby seat is further gripped the gripped object when said handle bar is pulled to a locking position, and the rubber pad on said handle bar is released from the bottom surface of the table to facilitate the separation of the baby seat and the table when said handle bar is pulled to a releasing position.
