BELT REEL ASSEMBLY FOR FASTENING GOODS ON A
TRUCK
The present invention relates to a belt reel assembly and, more particularly, to a belt reel assembly for fastening goods on a truck. The belt reel assembly can release the strain of the belt step by step.
A conventional belt reel assembly, as shown in Figs. 10 and 11 of the accompanying drawings, comprises an axle 81 extending through a main frame 82 and a lever 83 so as pivotally to connect the main frame and lever together. The axle 81 includes two opposite ends, each having a ratchet 84 engaged with the axle 81 and a diametrical slot 811 allowing a belt 9 to penetrate the axle 81 and be reeled on to the axle 81. A first stop plate 821 is slidably mounted in the main frame 82 and is selectively engageable with the ratchets 84 due to the restoring force of a spring 822 which is compressively mounted between the first stop plate 821 and the main frame 82. A second stop plate 831 is slidably mounted in the lever 83 and is selectively engageable with the ratchets 84 due to the restoring force of a second spring 832 which is compressively mounted between the lever 83 and the second stop plate 831. Consequently, the axle 81 is drivable to reel the belt 9 by the lever 83 when the lever 83 is turned backwardly relative to the main frame 82. The main frame 82 has a groove 823 for selectively receiving the second stop plate 831 and the second stop plate 831 is separated relative to the ratchets 84 when the second stop plate 831 is partially received in this groove. Furthermore, the lever 83 has a raised portion 833 which pushes the first stop plate 821 backwards to disengage the first stop plate 821 from the ratchets 84 when the second stop plate 831 is received in the groove 823. Then the axle 81 is in a free condition and the strain of the belt 9 is released.
<Desc/Clms Page number 2>
The foregoing belt reel assembly is usually provided to fasten the belt 9 for fixing goods on a truck. To operate the conventional belt reel, the belt has one end fixed on the truck and the other extending through the slot 811 of the axle 81 after passing over the goods and the main frame 82 is connected to a hook (not shown) which is detachably secured on the truck. The belt 9 is tightly reeled by the axle 81 to fasten the goods when the lever 83 is rocked back and forth to drive the axle 81. When releasing the belt 9, the lever 83 is turned to engage the second stop plate 831 partially received in the groove 823 and is separated from the ratchets 84. At the same time, the raised portion 833 of the lever 83 pushes the first stop plate 821 backwards to disengage the first stop plate 821 from the ratchets 84. Consequently, the axle 81 is in a free condition and the strain of the belt 9 is released to enable the operator to remove the goods from the truck.
However, the strain of the belt 9 is released in an instant such that the goods may fall from the truck at the time the strain of the belt (9) is released. This is very dangerous because the falling goods may hurt the operator.
An object of the present invention is to provide an improved belt reel assembly for fastening goods on a truck and which can release the strain of the belt step by step.
A belt reel assembly in accordance with the present invention comprises an axle extending through a main frame and a lever for pivotally mounting the main frame and the lever to each other, the main frame including two opposite sides each having an ear extending therefrom, the lever including two opposite sides each having an ear extending therefrom, the ears of the frame and the ears of the lever being parallel to and aligning with one another, the axle penetrating through the ears of the main frame and the lever, the axle including
<Desc/Clms Page number 3>
two opposite ends each having a ratchet mounted between the ears of the main frame and the lever for unidirectionally driving the axle, each ratchet having multiple teeth formed on an outer periphery thereof, the two opposite sides of the main frame each having a first slot defined therein and toward the ear of the main frame, a first stop plate laterally extending through the main frame via the first slots and partially received in the first slots, the first stop plate slidably mounted in the main frame and selectively engaging to a corresponding one of the teeth, a first spring mounted between the first stop plate and the main frame to provide a restitution force to the first stop plate, the two opposite sides of the lever each having a second slot defined therein and toward the ear of the lever, a second stop plate laterally extending through the lever via the second slots and partially received in the second slots, the second stop plate slidably mounted in the lever and selectively engages to a corresponding one of the teeth, a second spring mounted between the second stop plate and the lever to provide a restitution force to the second stop plate, the ear of the main frame having a sliding portion formed thereon, the sliding portion including first end connected to the main frame and a second end having a stopper radially extending from the ear of the main frame, a groove defined in the ear of the main frame opposite to the first slot and a raised portion extending from the ear of the lever to backward push the first stop plate, the groove having a width being approximately equal to a pitch between every two teeth, the groove including a limiting side formed adjacent to the stopper to prevent the second stop plate from escaping from the groove and a stopping side formed near the indentation, the second stop plate being separated relative to the ratchet when the second stop plate is limited by the limiting side, the raised portion of the lever backward pushing the first stop plate to be
<Desc/Clms Page number 4>
separated relative to the ratchet when the second stop plate abuts the stop side and is secured in the indentation.
The belt reel assembly of the present invention prevents the strain of the belt from being released instantaneously so that the goods may suddenly fall from the truck when the belt is released.
Consequently, unloading work is safer for the operator.

10 when the axle is in a free condition.
Referring to the drawings and initially to Figs. 1-6, the belt reel assembly in accordance with the present invention comprises an axle 3
extending through a main frame I and a lever 2 and pivotally connecting the main frame 1 and the lever together. The main frame 1 includes two opposite sides each having an ear 101 extending therefrom. The lever 2 includes two opposite sides each having an ear
201 extending therefrom. The ear 101 of the main frame I and the ear
201 of the lever 2 are parallel to and align with each other. The axle 3 projects through the ears 101, 201 of the main frame I and the lever 2.
It includes two opposite ends each having a ratchet 32 in the form of a wheel mounted between the ears 101, 201 of the main frame I and the lever 2 for driving the axle 3. Each ratchet 32 has multiple teeth 321 formed on a periphery thereof. Each tooth 321 has a sliding side 322 shaped to allow a first stop plate I I and a second stop plate 21 to be moved to an adjacent tooth 321 of the ratchet 32. The axle 3 has a diametrical slot 31 extending through the axle 3. The slot 31 is adapted to allow a belt 4 to penetrate the axle 3 and be wound on to the axle 3.
The two opposite sides of the main frame 1 each has a first slot 102 formed therein and directed towards the ear 101 of the main frame 1. The first stop plate 11 extends laterally through the main frame 1, via the first slots 102, and is partially received in the first slots 102.
The first stop plate 11 is thereby slidably mounted in the main frame 1 and is selectively engageable with to a corresponding one of the teeth 321 of the ratchet 32. A first compression spring 12 is mounted between the first stop plate 11 and the main frame 1 to apply a restoring force to the first stop plate 11.
The two opposite sides of the lever 2 each has a second slot 202 formed therein and directed towards the ear 201 of the lever 2.
<Desc/Clms Page number 6>
The second stop plate 21 extends laterally through the lever 2, via the second slots 202, and is partially received in the second slots 202. The second stop plate 21 is thereby slidably mounted in the lever 2 and is selectively engageable with a corresponding one of the teeth 321 of the ratchet 32. A second spring 22 is mounted between the second stop plate 21 and the lever 2 to apply a restoring force to the second stop plate 21.
The ear 101 of the main frame I has a sliding portion 13 formed thereon. The sliding portion 13 includes a first end connected to the main frame 1 and a second end having a stop 16 radially extending from the ear 101 of the main frame 1. A groove 15 is formed in the ear 101 of the main frame 1 opposite to the first slot 102.
An indentation 14 is formed in the ear 101 of the main frame I below the groove 15 relative to the stop 16. A raised portion 23 extends from the ear 201 of the lever 2 for pushing the first stop plate 11 backwards.
The second stop plate 21 is engaged with the ratchets 32 when the second stop plate 21 is moved within the sliding portion 13 and then the raised portion 23 is separated relative to the first stop plate 11. The stop 16 projects, relative to the axle 3, further than the outer periphery of the ratchet 32 such that the second stop plate 21 is separated from the ratchet 32 when the second stop plate 21 is moved over the stop 16. The groove 15 has a width approximately equal to the pitch between every two teeth 321 of the ratchet 32. The groove 15 includes a guiding side 151 formed adjacent to the stop 16 and a stopping side 153 formed near the indentation 14. A recess 152 is formed in the guiding side 151 near the top of the stop 16 to prevent the second stop plate 21 from escaping from the groove 15 along the guiding side 151. The guiding side 151 corresponds to one of the sliding sides 322 of the ratchets 32 and the distance between the recess
<Desc/Clms Page number 7>
152 and the axle 3 is greater than that between the top of a tooth 321 and the axle 3 such that the second stop plate 21 is separated from the ratchet 32 when the second stop plate 21 is engaged to the recess 152.
The raised portion 23 of the lever 2 pushes the first stop plate 11 backwards to separate it from the ratchet 32 when the second stop plate 21 abuts the stop side 153 or is secured in the indentation 14.
With reference to Fig. 2, the second stop plate 21 is engaged with the ratchet 23 when moved within the sliding portion 13 of the main frame 1 and the ratchet 23 is unidirectionally engaged with the first stop plate 11. Consequently, the axle 3 is driven and rotates to reel and tightly pull the belt 4 for fastening goods.
With reference to Figs. 3 and 4, when releasing the belt 4, the second stop plate 21 is pulled downwardly relative to the ratchet 32 and the lever 2 is turned to move the second stop plate 21 over the stop
16 and position it within the groove 15 where it abuts the sliding side 322 of the tooth 321 of the ratchet 32. Meanwhile, the first stop plate
I I remains engaged with the ratchet 32. The first stop plate 11 is pushed backward and separated from the ratchet 32 such that the axle 3 and the ratchet 32 are in a free condition. Consequently, the axle 3 and the ratchets 32 are reversed due the strain of the belt 4.
With reference to Figs. 5 and 6, the reversing of the axle 3 and ratchets 32 drives the lever 2 towards the recess 152 and the raised portion 23 is moved away from the first stop plate 11 such that the first stop plate 11 is engaged with an adjacent tooth 321 to prevent the strain of the belt 4 from being released instantaneously. At the same time, the tooth 321 pushes the second stop plate 21 along the guiding portion 151 until the second stop plate 21 engages the recess 152, whereupon the tooth 321 pushing the second stop plate 21 passes under the second stop plate 21. Repeating the steps illustrated in Figs 3-6, the releasing range
<Desc/Clms Page number 8>
of the belt 4 is equal to the pitch of the teeth 321 of the ratchet 32 such that the present invention mitigates and/or obviates the disadvantages of the conventional belt reel assembly which releases the strain of the belt 4 instantaneously.
With reference to Figs. 6 and 7, the operator can backward pull the second stop plate 21 backwards and turn the lever 2 so as fix the second stop plate 21 in the indentation 14 where the strain of the belt 4 is released. Then the ratchet 32 and the axle 3 are in a free condition so that the operator can pull the belt 4 from the belt reel assembly for conveniently unloading goods from a truck.
Figs. 8 and 9 illustrate another embodiment of the present invention, wherein the groove 55 has a limiting side 552 formed adjacent the stop 56 and the tooth 721 has a stop portion 723 along a diameter of the ratchet 72 and a guiding portion 722 obliquely connected to the stop portion 723 of an adjacent tooth 721 of the ratchet 72. A gap A is defined between the second stop plate 61 and the limiting side 552 of the groove 55 when the first stop plate 51 is engaged with the ratchet 72. The gap A is provided partially to receive the second stop plate 61 such that second stop plate 61 can drive the ratchet 72 and rotate the axle 3 tightly to reel the belt 4. Repeating the releasing steps of the above-mentioned embodiment of the present invention, the first stop plate 51 is engaged with the ratchet 72 and the second stop plate 61 is clamped between the limiting side 552 and the stop portion 723 of the tooth 721 when the ratchet 72 reverses to a pitch of each two teeth 721 of the ratchet 72. The second stop plate 61 is pulled backwards over the tooth 721 for the next releasing step.
As described above, the belt reel assembly in accordance with the present invention has been designed to mitigate and/or obviate the disadvantages of a conventional belt reel assembly and prevents the
<Desc/Clms Page number 9>
strain of the belt from being released instantaneously so that goods suddenly fall from the truck when the strain of the belt is released.
Consequently, unloading work is safer for the operator.
