Description
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.

62
is pulled to a releasing position, the handle bar
62
is maintained in a releasing state by the elastic force of the third spring
65
while the rubber pad
66
on the handle bar
62
is released from the bottom surface of the table to facilitate the separation of the baby seat and the table.
With reference to
FIG. 1
, the seat portion
70
includes a seat cushion
71
and a back portion
72
. The seat portion
70
is made of a soft cloth material and the back portion
72
is hanged on the U-shaped arm member
21
by sewing. Two ends of the back portion
72
passing over the soldered portions of the two ends of the longitudinal arm members
30
and
35
and the straight arm members
22
and
23
are fastened to the back portion
72
by buttons so that the seat portion
70
is secured to the U-shaped arm assembly
20
so as to prevent the seat portion
70
from sliding due to the action of a baby. A safety belt
73
is provided in the inner side of the seat portion
70
for fastening the baby so as to prevent the baby from falling to ground, which results in a dangerous situation. The rear side of the seat portion
70
is provided with a bag for a convenient purpose.
Such a baby seat achieves the following functions.
(1) An elevation adjusting function can be obtained for allowing the baby seat to be suitable for gripped objects with various thicknesses. This function can be carried out by using a self-lock action induced from the friction between the stop strip
58
and the longitudinal arm member
30
. When the elevation adjusting and locking portion
51
is in a normal state, the stop strip
58
is maintained at its operating position through the elastic force of the first spring
55
so that the elevation controlling and adjusting member
50
is fixed at a certain position. When the baby seat needs to be adjusted, the adjusting button
54
and the locking button
56
of the elevation adjusting and locking portion
51
are simultaneously pressed so that the longitudinal arm member
30
is released from the stop strip
58
and the elevation controlling and adjusting member
50
is allowed to be upwardly and downwardly movable in the elevation direction of the longitudinal arm member
30
.
(2) A function of securely locking the baby seat to prevent from misoperation is obtained so that the use of the baby seat is safer and more reliable. This function can be carried out by an allied operation of the adjusting button
54
and the locking button
56
of the elevation adjusting and locking portion
51
. When the locking button
56
is not pressed, the longitudinal arm member
30
cannot be released from the stop strip
58
by pressing only the adjusting button
54
, and the relative position between the locking button
56
and the adjusting button
54
is maintained by the second spring
57
.
(3) Functions of gripping, locking and releasing of the release-or-grip control portion
61
is obtained by applying a self-lock principle to keep the handle bar
62
more reliably tightly locked. When the handle bar
62
is in a locking state and the baby seat is tightly gripped and locked, a pre-pressing force is applied to the handle bar
62
by the third spring
65
. At this time, if the baby seat is pulled outside, the baby seat will be more tightly gripped since the relation between the handle bar
62
and the gripped object is in a self-lock state due to the friction therebetween. When the handle bar
62
is in a releasing state, the handle bar
62
is separated from the gripped object and will be kept in the releasing state due to the elastic force of the third spring
65
.
Therefore, as compared with the conventional baby seat, the operation of the hook-on type baby seat in accordance with the present invention is simple and labor-saving. The baby seat can be adjusted so as to be suitable for gripped objects with various thicknesses, as long as the adjusting button and the locking button are pressed at the same time. The gripping and releasing operations of the baby seat can be realized by only pulling the handle bar forwardly and backwardly. In addition, the baby seat is comfortable in use and pleasant to the eyes since the baby seat is made of soft cloth. Further, the additional bag makes the use of the baby seat more convenient, and the compact retracting size is in favor of the carry and the portability of the baby seat.
While the present invention has been described in detail and pictorially in the accompanying drawings, it is not limited to such details since many changes and modifications recognizable to those skilled in the art may be made to the invention without departing from the spirit and the scope thereof.
