Description
BINDING DEVICE
BACKGROUND OF THE INVENTION
1.Field of the Invention
The present invention relates to a binding device, particularly to a binding device which has a roll with separable roll sectors, so that easy mounting and dismounting of a belt is achieved, and which allows for a wider range of applications.
2.Description of Related Art
As shown in Fig. 5, a conventional binding device la is used to pull tight a belt assembly for fixing and securing a load on a vehicle. More specifically, the binding device 1 a is used to pull together connecting ends of upper and lower belts 1 Oa, 1 2a, with engaging elements 14a, 16a on far ends thereof, e.g. hooks or rings, which engage with fixed counterelements, e.g. hooks on the vehicle. The binding device Ia comprises: two ratchet wheels 2a, surrounding central holes 21a; a roll 3a, mounted on two ends thereof in the central holes 21 a and having a longitudinal slit 31 a, into which the upper belt lOa is inserted; a lever 4a, shaped like the letter U, having a Lower end with an opening that is fixed on one of the ratchet wheels 2a and the roll 3a and having an upper end with a handle 43a for manually lifting the lever 4a, a frame 5a, shaped like the letter U, having a connecting end fixed on another of the ratchet wheels 2a and having a free end to which the lower belt I 2a is fastened; and upper and lower blocking assemblies 6a, 7a. The upper blocking assembly 6a comprises: an upper blocking element 61a, shaped like the letter U and mounted on a middle section of the lever 4a, transversally glidable thereon and in a first blocking position thereof t L-blocking one of the ratchet wheels 2a from turning back; a spring 63a, at a front end pushing the upper blocking element 61a towards the first blocking position; and a spring support 65a, mounted on the lever 4a and supporting a rear end of the spring 63a. The lower blocking assembly 7a comprises: a lower blocking element 71a, shaped like the letter U and mounted on a middle section of the frame 5a, transversally glidable thereon and in a second blocking position thereof blocking one of the ratchet wheels 2a from turning back; a spring 73a, at a front end pushing the lowper blocking element 71a towards the second blocking position; and a spring support 75a, mounted on the frame 5a and supporting a rear end of the spring 73a. For using the binding device Ia, the lever 4a is repeatedly pushed towards the frame 5a and pulled away therefrom, so that the belts I Oa, I 2a are pulled together with great force due to a lever effect and at the same time prevented from loosening, so that cargo on a vehicle is fixed and secured.
For securing cargo, binding devices as described above play an important role.
IS However, since the slit 31 a has to accommodate connecting ends of upper belts of various width, the latter are in many cases not laterally fixed. Furthermore, for binding cargos of great variety, long upper belts are usually used, so that often long connecting ends have to be pulled through the slit 3 la, while the upper and lower blocking elements 61a, 71a have to be kept from blocking the ratchet wheels 2a, wasting time.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a binding device which allows for fast and convenient mounting and dismounting of belts.
Another object of the present invention is to provide a binding device which has a wider range of applications.
Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in Figs. 1 and 2, the binding device of the present invention is used to pull together connecting ends of upper and lower belts 10, 12, comprising a lever 4, a frame 5, and upper and lower blocking devices 6, 7. The binding device of the present invention is characterized by fuither comprising ratchet wheels 2 with inner and outer peripheries, carrying inner and outer protrusions 23, 25, respectively, which form an axis of a movement of the lever 4 and the frame 5 against each other. A roll 3 of varying width is set on the inner and outer protrusions 23, 25, thereby readily being replaceable, so that the upper belt 10 is quickly inserted or pulled out. In the
following, a detailed description is given.
Each of the ratchet wheels 2 has a plurality of mount openings 21, 22, in which a first roll sector 33 and a second roll sector 35 are mounted. There are two or more mount openings and roll sectors, the present text uses two as an example.
The roll 3 comprises the first roll sector 33, the second roll sector 35, and a fixing assembly 8. The first roll sector 33 is mounted in the mount opening 21, having a free end, and is removable to allow for inserting of the upper belt 10. The second roll sector 35 is mounted in the mount opening 22, having a free end. A gap 31 lies between the first and second roll sectors 33, 35. The fixing assembly 8 comprises: a transverse hole 84, passing through the free end of the first roll sector 33; a first fixing hole 83, passing through the free end of the first roll sector 33, oriented perpendicularly to the transverse hole 84; a second fixing hole 81, passing through the free end of the second roll sector 33 and aligned with the first fixing hole 83 when the first roll sector 33 is inserted in the mount opening 21; two first pins 88, entering the transverse hole 84 from opposite ends thereof; a handle 87, shaped like the letter U and having ends to which the first pins 88 are respectively attached, so that the first roll sector 33 is readily manually moved, furthermore having lever holes 91 close to the ends thereof; a connecting piece 89, shaped like the letter U and having ends with end holes 93, through which second pins 95 pass, which in turn pass through the lever holes 91; and a bolt 85, passing through the first fixing hole 83 of the first roll sector 33 and having a free end with a mounting hole 86, passed through by the connecting piece 89. Moving the handle 87 towards the first roll sector 33 drives a movement of the connectmg piece 89, pushing the bolt 85 deeper into the first fixing hole 83 and finally into the second fixing hole 81 of the second roll sector 35. Then the first and second roll sectors 33, 35 are connected to each other. Moving the handle $7 away from the first roll sector drives an opposite movement of the connecting piece 89, pulling the bolt 85 out of the first fixing hole 83, so that the bolt 85 leaves the second fixing hole 81 of the second roll sector 35. Then the first roll sector 33 is longitudinally removable. Thereby, mounting and dismounting of the upper belt 10 is quickly and easily performed.
Since there is no need to pass the upper belt through the gap 31, engaging elements 14 (not shown) are attached without restriction, and mounting and dismounting times are reduced.
The present invention is also applicable to a single belt with engaging elements on opposite ends thereof. For usage, one end of the belt is fixed and wound around cargo to be secured, an opposite end is fixed, and a middle section is fold and inserted into the gap between the roll sectors and pulled tight by repeatedly moving the lever and the frame against each other (not shown).
Each of the roll sectors 33, 35 of the roll 3 is designable to be removable (not shown).
The roll sectors 33,35 are realizable with any cross-sections, the semi-circular cross-sections shown in the Figs. being examples.
Referring to Fig. 3, the present invention in a second embodiment has two ratchet wheels 2b and a roll 3b with first and second roll sectors 33b, 35b which are both removable. On both ends of the roll 3b, a fixing assembly 8 is attached. For mounting the roll 3b, each of the ratchet wheels 2b has a support 27 with a mounting hole 29 into which the bolt 85 is inserted, so that the roll 3b is fixed.
Referring to Fig. 4, for saving manufacturing cost and more convenient
F
production,the present invention in a third embodiment has ratchet wheels 2c, each comprising an inner half 20a with a circular inner protrusion 23c. and an outer half 20b with a circular outer protrusion 25c.
The present invention offers the following advantages: 1. Fast mounting and dism unting of belts; 2. an extended range of applications; 3. no need for passing a belt through a gap and pulling out a belt therefrom; 4. saving manufacturing cost.
While prefened embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
