ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a net for fastening things, and particularly to one which is used to fasten luggage carried on the luggage rack of a station wagon, jeep, etc.
Station wagons or jeeps can carry luggage on the luggage rack on the top thereof, and nets are used to fasten the luggage; it is very convenient in travelling.
Referring to
FIGS. 10
,
11
and
12
, a heretofore known net for fastening things comprises a central ring
10
, several longitudinal ropes
11
, and transverse ropes
12
.
Each of the longitudinal ropes
11
is connected to the central ring from two ends thereof. Referring specifically to
FIG. 12
, the ends each forms a connecting loop
111
,
112
around the central ring
10
, and is fixed by a fixing element
13
.
The two connecting loops
111
,
112
of each of the longitudinal ropes
11
are arranged such that one connecting loop
111
′ of the adjacent longitudinal rope
11
′ is located therebetween.
The transverse ropes
12
are each arranged across the longitudinal ropes
11
, forming a circle around the central ring
10
; two ends of each of the transverse ropes
12
are fastened to each other by a fixing element
13
. The contact point between of the longitudinal ropes
11
and the transverse ropes
12
are also fastened with fixing elements
13
.
Each of the contact points between outward portion of the longitudinal ropes
11
are connected to a respective hooking element
14
.
Thus, the net can be used to fasten the luggage on the top of a station wagon with the hooking elements
14
connected to the luggage rack.
However, it is found that the above said fastening net has undesirable features as follows.
1. Being elastic, the longitudinal ropes and the transverse ropes will get thinner when pulled. So, when the net is used to fasten things, the ropes are thinner. Because all the contact points of the ropes are fixed by fixing elements, the fastening net cannot fasten the things any longer when the fixing elements become loose and fall off the ropes.
2. The fastening net is made of relatively many parts so the manufacturing thereof is a waste of labor, and the cost is relatively high.
SUMMARY OF THE INVENTION
It is a main object of the present invention to provide a fastening net for use on the top of a car, which is strong and can be manufactured cost-effectively.
The fastening net of the present invention comprises a rope, several fixing elements, hooking elements and a central fixing element.
In making the fastening net, the rope is firstly arranged to have a first “8” formed diagonally across a predetermined square defining the dimension of the net. Then, a second, a third, and a fourth “8”s are formed in a similar way to constitute the major part of the net. The rest of the rope is arranged across the intermediate portions of the “8”s, approaching the center of the net. The fixing elements are each coupled to a respective one of the intersections of all parts of the rope. The hooking elements are fixed to the part of the rope constituting the edge of the net.
The central fixing element consists of a cover and a base; the cover has engaging protrusions spaced apart on an edge. The base has engaging sockets spaced apart on an edge, and confining gaps adjacent to the engaging sockets. The parts of the “8”s near the center of the net are passed through the central fixing element, and fixed between the confining gaps and the cover. The engaging protrusions of the cover are passed into the engaging sockets of the base for the base and the cover to be firmly connected to each other.
The fastening net is made of a single rope so it is stronger and can be made relatively easily when compared with the prior art fastening net.
