ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an improved reel device, especially to a reel device capable of tight connection with a decorative piece or various modeling decorations. The interior volume of the reel can be enlarged to allow convenient rotation of 360 degrees of the reel.
The reel involved in the present invention is especially suitable for carrying on the waist of a person, and can be used as a measuring tape, a stretchable key collecting device, or a belt device carried on one's person for taking a pet outdoors. Such a reel is provided centrally and internally with a coil spring and a rope or a measuring tape which can be pulled outwardly and can be reeled back by the internal coil spring when a pulling force is removed.
2. Description of the Prior Art
FIG. 1
shows an analytic structure of such a conventional reel; the main housing of the whole reel is comprised of an upper lid
11
and a bottom lid
12
. The reel is further provided with a collar
13
, an upper cover
14
and a lower cover
15
to form together a reel axle. The collar
13
is provided therein with a coil spring
16
, the above mentioned members can be serially connected by means of a mandrel
17
.
Among the conventional reels, the reel which reels and releases a rope and a coil spring is comprised of an upper cover
14
and a lower cover
15
and a collar
13
. The covers
14
and
15
are provided respectively with spaced connecting holes
141
,
151
at the periphery of the collar
13
. The collar
13
is provided on both sides thereof with a plurality of insertion lugs
131
,
132
. The insertion lugs
131
on one side are inserted into the connecting holes
141
of the cover
14
, while the insertion lugs
132
on the other side are inserted into the connecting holes
151
of the other cover
15
. Then the insertion lugs
131
,
132
are bent in position, and a reel axle is completed, the coil spring
16
can be placed within the covers
14
and
15
and in the interior
133
of the collar
13
. The external peripheral surface
134
of the collar
13
is used for reeling thereon a pulling rope of desired length (not shown). The defect resided in such a conventional reel axle structure is that: the collar
13
must be of a size in pursuance of the diameter of the circles having the spaced connecting holes
141
,
151
thereon of the covers
14
and
15
respectively, thereby the interior
133
of the collar
13
is limited and smaller. The collar
13
can not receive a larger coil spring
16
, and the force for reeling back resiliently is smaller too. And more, the collar
13
must be provided with a plurality of insertion lugs
131
,
132
of suitable length for assembling the covers
14
and
15
, thereby the external peripheral surface
134
thereof for reeling and releasing a pulling rope is limited in width. In other words, the pulling rope can not be longer for measuring or pulling outwardly to a larger distance.
Moreover, the upper lid
11
must be provided with a central hole
111
for riveting an end
171
of the mandrel
17
. And the central hole
111
must be punching molded to form therearound a concave annular area
112
for mounting on the exterior surface of the upper lid
11
a decorative piece (not shown). The concave annular area
112
for mounting the decorative piece can obscure the rivet connection to form a more beautiful exterior surface
113
on the upper lid
11
of the reel. However, the concave annular area
112
provided on the exterior surface
113
is lowered to a certain depth which includes two defects. One is that the die for forming the concave annular area
112
will make the concave annular area
112
an arciform section, and a slit may form when the decorative piece closes it to create a less even and less aesthetic external decorative piece. While the other defect is that, if modeling of the concave annular area
112
for mounting the decorative piece is to be changed, the cost of a new die required is too expensive and is uneconomic.
Further as shown in
FIG. 2
, the reel proper
10
can be provided on one side thereof with a clamp
18
fixedly or movably riveted on the end
171
of the mandrel
17
. The clamp
18
is provided with a clamping mouth
181
. An exposing pulling control member
19
can be fixed on one end of a pulling rope
101
. The pulling rope
101
is extended through a central hole
191
provided in the top surface of the pulling control member
19
and is fixed in position by tying a knot. After the clamp
18
is clamped on a waist belt by the clamping mouth
181
, if it is fixedly riveted on the end
171
, the pulling control member
19
can only pull the pulling rope
101
out in a single direction; if it is movably riveted on the end
171
, the whole reel
10
can be controlled by pulling in the whole circle taking the movable riveting point as an axis. But the movable axis is formed from a rivet; it is not smooth in rotating and is subjected to getting jammed.
The structure assembled from the pulling rope
101
and the pulling control member
19
makes the pulling rope
101
subjected to damage and breaking by rubbing due to the friction induced at the periphery of the central hole
191
provided in the top surface of the pulling control member
19
. This is one of its defects. When pulling force is removed, the whole pulling rope
101
will be reeled back into the reel by a coil spring in the reel. However, such a conventional structure assembled from the pulling rope
101
and the pulling control member
19
cannot make the pulling control member
19
get back to its original position accurately and automatically.
SUMMARY OF THE INVENTION
The object of the present invention therefore is to provide a reel device portable with one's person. An upper lid of the reel device is provided therein with a lining sleeve which slightly protrudes for assembling with a bottom lid. A reel axle is provided between the reel device and the bottom lid; the reel axle is comprised of a male upper cover and a female lower cover. Wherein, the male upper cover is provided with a connecting bowl having a suitable diameter, while the female lower cover is correspondingly provided with a fitting-over collar matching with the connecting bowl. When the bowl and the collar are fittingly connected with each other, a larger space for reeling and releasing a coil spring and a pulling rope is formed therebetween. Thereby, reeling-back force of the reel portable with one's person and length of the pulling rope can be increased.
Another object of the present invention is to provide a reel device portable with one's person, wherein, the upper lid can be directly provided with a hole for a decorative piece. The hole can more tightly contact the decorative piece, so that the decorative piece can be gotten rid of non-elegant angular portions.
Another object of the present invention is to provide various modeling for the decorative piece on the upper lid in a more economic way.
A further object of the present invention is to provide directly a pad between the upper lid and the lining sleeve which is assembled with the upper lid. The pad can be used to directly form a decorative surface without providing an additional decorative piece.
In another preferred embodiment of the present invention, a clamp is provided on its connecting side with a protruding annulus having a hole therein and to be inserted into a corresponding concave portion provided on one side of the reel body. And a bolt is extended through the hole to lock with fittings in the reel body. The bolt is extended into the reel body and the clamp with its neck portion. The neck portion functions as an axis and can be rotated smoothly within 360 degrees. The pulling rope can be added on the end thereof with a ball which can be fitted in a pulling control member as a force bearing portion. Thereby, the assembly of the clamp and the reel body can be rotated conveniently in a whole circle, and the pulling control member can be pulled out in any
