Description

  The present invention relates to a winch, a vehicle equipped with the winch, and a method for operating the winch, and a method for fixing a load to the vehicle with a tether strap corresponding to the winch. The winch is particularly useful for various types of transport vehicles such as flat bed trucks, rail vehicles.

  It is well known in the industry that a trailer with a platform is a road vehicle with a loading platform. There are various types of luggage that can be transported in such a platform-equipped vehicle carrier, generally heavy, palletized, and / or other types that require the use of a traction mechanism such as a hoist for handling. The object is typically taken in and out from either the side or top of the vehicle.

  It is also well known in the industry that transport vehicles of the type described above are generally equipped with lateral fixing devices, which are typically arranged in corresponding horizontal rails or trucks along the longitudinal axis of the loading platform. It is. The users of these vehicles meet the safety standard requirements regarding the use of fixing devices with sufficient load capacity, i.e. whether the required number is determined according to the maximum load to be carried and the length of the load to be fixed. There must be.

  As a typical fixing device, it is fastened and fixed by a winch which is very well known in the industry. In practice, this type of winch is typically attached to a trailer, and more specifically fitted into rails on each side of the trailer and placed in the desired location. The winch is used to tighten fastening belts and chains, also known as straps, and other fastening aids used to secure various loads carried by the trailer.

  There are several types of rails known in the industry. Most trailers have a winch fitted into the rail by a corresponding groove in the winch. Other trailers have the winch fitted into the rail by an optional plate that is typically welded to the top of the winch. Still other trailers may use other suitable attachment means.

  Conventional tie-down winches generally have a slit for receiving one end of a tether strap, a reel for winding the strap, and a hole for receiving the take-up bar so that the strap can be wound onto the reel and tightened. Or it has an opening. Generally, the belt is attached to the conventional winch as follows. First, the belt is inserted into the slit or opening of the winch reel. This step is only performed when the belt is first attached to the winch. Next, the belt is further wound on a winch reel. The belt is generally wound manually. Pass the belt further to the load, fasten it to the other side of the trailer with its hook, and tighten it properly on the reel with the take-up bar. Conventional tie-down winches are typically provided with a ratchet safety mechanism to maintain constant tightening of the strap and prevent it from unraveling.

  A problem associated with this type of tie-down winch and tightening method is that the winch cannot be tightened to some degree with certainty when not in use. In fact, this can be explained by the fact that the winch moves in the same direction as the force applied during tightening and induces premature wear of the trailer rails caused by vibrations as the vehicle moves.

  It is also well known in the industry that the operation of a conventional winch and the corresponding belt is typically performed with a take-up bar that is typically inserted into a corresponding hole on the right side of the winch. Loosen the belt by pressing down on the bar. However, in order to rotate the reel freely, the latch must be raised. This process is difficult because the driver needs to use both hands to operate the bar and latch simultaneously. The belt is then unwound to the desired length by simply pulling. Then, hook the belt on the baggage and pass it to the other side of the trailer. The belt is then fastened to the trailer support (or rail) on the opposite side of the trailer with its hook.

  Then, as described above, the remaining belt is manually wound on the winch reel to adjust the length. Insert the bar into the hole or opening on the right side of the winch. Then push the bar down to tighten the belt. This tightening method is well known in the industry that the user needs to exert a great deal of force on the bar, so that various body parts of a typical tie-down winch user are scratched, i.e. strained and burdened. It is known to occur. Also, since the tightening force transmitted to the tightening belt is directly proportional to the force applied by the user using the bar, the physical force required by the user and the resulting fatigue are generally different. It has also been found that there is an adverse effect on the tightening tension applied to (such as non-uniform or non-uniform).

  In addition, since the belt is rolled up several times, the part where the belt is wound loosens, and the belt tension is lost. I know I need to re-tighten.

  Another type of securing device known in the industry is typically known as a chain vendor. A typical chain vendor generally includes a vendor and a clamping bar. The chain corresponding to this chain vendor is often stored in the rear of the vehicle when not in use. Similar to a tether strap, the chain is typically hooked on a load and fastened to the trailer support (or rail) on the opposite side of the trailer with the hook.

  It is well known in the industry to hook the vendor to the chain link and trailer support. Chain vendor hooks must be transferred to the link and tightened. Furthermore, the tightening bar is fitted into the handle of the chain vendor, and the chain is tightened with the tightening bar.

  It is well known in the industry how often the link used does not sufficiently tighten the chain. As a result, it is very difficult to obtain an appropriate tightening force. Also, in order to avoid having to open the vendor itself or retighten the vendor (waste time), the chain vendor handle is often doubled with an elastic belt provided on the hook.

For patents and patent applications disclosing various winches and various accessories for use therewith, the applicant is aware of the following:
Canadian Patent No. 2230620 Canadian Patent No. 2354934 U.S. Pat. No. 4,823,443 US Pat. No. 5,156,506 US Pat. No. 5,295,664 US Pat. No. 5,346,653 US Pat. No. 5,466,030 US Pat. No. 5,853,164 US Pat. No. 6,102,637 German Patent Application No. 4226083

  Various disadvantages associated with the various conventional winches described above are also well known in the industry. In fact, with regard to strap or chain tightening, conventional winches use the lever principle to allow strap or chain tightening. In fact, a winch user must apply a great deal of force to push the bar down to insert the bar (typically 3 feet long) into the corresponding hole in the winch reel and tighten the fastening strap. Don't be. A substantial disadvantage of the tightening method described above is that it is very forceful and can cause serious injury and / or injury to the user. Furthermore, due to the poor design and parts of the typical tie-down winch described above and the corresponding strap, tightening is often uneven due to the different winch of the trailer. This is because the fatigue level of the user increases from the tightening of the first winch to the tightening of the next winch. In fact, it has been found that there is a big difference in the tightening tension between the first winch tightened by the user and the last winch tightened by the user, which in turn leads to an unbalanced tightening of the load supported by the vehicle. As can be easily understood, it is highly undesirable for reasons of stability.

  Another major drawback associated with conventional winches is that the clamping force is not constant and uniform. As mentioned above, the fastening strap does not have a sufficient clamping force and / or there is a difference in the clamping force depending on the strap, which increases the possibility of the baggage slipping or sliding down during transport Not desirable.

  Another disadvantage associated with conventional winches is that the tension applied to the belt is maintained by a latch attached to the winch frame, which interferes with the reel. For this reason, when the trailer is retracted, pressure is distributed to the winch frame by latches, which further distorts the winch by impact and makes it easier to unpack the load, which is highly undesirable for obvious reasons well known in the industry.

  Another problem associated with conventional winches is undesirable because the tightening tension is lost by being wound on the reel of the winch while the belt is being tightened and the belt itself is compressed. This also results in uneven tightening of the trailer with different winches, which further induces trailer deformation and premature wear. Furthermore, as a result of the above, belt tension is lost due to vibrations during transport, so the driver must stop the vehicle frequently and re-tighten the belt several times during movement. Also, if sand, dust and / or other foreign matter enters between the belts, the belt wears quickly.

  Another problem associated with conventional winches is that the belt must be manually wound up to its full length on a winch reel and then securely tightened with a take-up bar. This is undesirable because it is a time-consuming procedure. Furthermore, since the winch moves in the same direction as the clamping force, the winch cannot be securely fastened to the trailer rail. Furthermore, when the vehicle moves, the winch vibrates, and the trailer rail to which the winch is attached wears. In fact, in some cases, the rails must be replaced every year, which is very expensive.

  Another problem associated with conventional winches is that the user must raise the latch so that the reel does not get in the way while trying to loosen the belt with the take-up bar. Since the user must use both hands to operate the latch and the take-up bar at the same time, it is very undesirable because the winch is difficult to operate.

  Another problem associated with conventional winches and the chain vendors used with them is that again, the principle of leverage is required to tighten the chain, and eventually the same drawbacks associated with conventional winches and their straps. Is to occur. In fact, this method is physically burdensome and can cause serious injury and / or injury to the user of the winch. In addition, the user often has to straddle the load to operate the chain vendor, which can cause the user to fall off the load or be seriously injured. Further, since the tightening process is performed based on the length of a link of a certain chain, the tightening is often insufficient or excessively tightened, which results in inappropriate tightening or damage to the equipment.

  Thus, in view of the above, there is a need for an improved winch that can overcome some of the problems of the prior art described above based on design and parts.

  The object of the present invention is to provide an improved winch of other related winches that meets some of the above needs and is therefore well known in the prior art.

Preferably, the winch 1 can work with a crank ratchet provided with a hex socket fitted to the corresponding head to transmit the required force and turn the corresponding component in a given direction or in the opposite direction. . For this reason, it is preferable that the head has a shape that can be operated with the same tool. Some heads (eg, the head of the clamping reel 13 or the take-up reel 29, etc.) may be manipulated by other suitable means, such as by hand, as will be apparent to those skilled in the art.

  In accordance with an embodiment of the present invention, the gear assembly 5 can include a ratchet wheel 65 and a pawl lever 67. The pawl wheel 65 is preferably fixedly attached to the tightening reel 13, and the pawl wheel 65 includes a plurality of outer edge teeth so that the pawl wheel 65 can rotate together with the reel. The pawl lever 67 has an end portion that is preferably disposed adjacent to the pawl wheel 65, the end of the pawl lever 67 being spaced from the pawl wheel 65, and the pawl lever 67 end portion being pawl. It can operate between a second configuration inserted into the corresponding tooth of the wheel 65, thereby preventing the pawl wheel 65 and the clamping wheel from rotating further along a given direction.

  Preferably, as shown in FIG. 26, the pawl lever 67 can be separated so that the pawl wheel 65 can be rotated in both directions. However, as shown in FIG. 27, when engaging with the pawl wheel 65, the pawl lever 67 blocks the wheel so that the rotation is only possible in the tightening direction so that the belt cannot be unwound. The pawl lever 67 is shaped and sized to be biased by gravity to bias it to the second configuration, and the first configuration is such that, for example, only when the user operates by hand. May be. Further, according to the present invention, the presence of the pawl wheel 65 is not necessarily required. Due to the nature of the interaction between the gear 17 and the worm 19, the gear assembly 5 is adapted to maintain the clamping assembly 3 in a corresponding clamping configuration so that the worm 19 meshes with the gear 17, so that the clamping reel 13 Can also be viewed as a locking and / or driving configuration that engages.

  Preferably, the winch 1 includes a rod 69 attached to the take-up reel 29 so that the slit is positioned between the rod 69 and the take-up reel 29 so that the slit can receive the end of the strap 15. Shape and size. That is, this makes it possible to easily wind the remaining portion of the strap 15 around the winding assembly 27.

  As can be readily appreciated from the foregoing, the optimal embodiment of the winch 1 shown in the accompanying drawings is preferably to minimize the components and assembly process, while the winch 1 and the corresponding strap 15 carry the load. The aim is to provide an appropriate method for anchoring to a transport vehicle easily, quickly and safely.

  In addition, according to another aspect of the present invention, there is also provided a transport vehicle comprising a winch 1, such as that described and illustrated herein, as illustrated in the accompanying drawings.

  According to yet another aspect of the present invention, there is also provided a method for operating the aforementioned winch 1, that is, a method for anchoring a load to a transport vehicle with the strap 15 corresponding to the winch 1, the method comprising a) the aforementioned B) attaching the winch to the corresponding side track of the carriage, c) attaching the first end of the strap 15 to the tether, and d) the strap 15. And a step of rotating to tighten the strap 15 on the tightening reel 13.

  Preferably, step e) comprises the step of f) operating the worm 19 in the second configuration and rotating the clamping reel 13 via the gear 17. Also preferably, the method further comprises: g) attaching the take-up assembly 27 to the fastening assembly 3 of the winch 1; and h) taking up the remaining portion of the strap 15 on the take-up reel 29 of the take-up assembly 27. It has.

  The winch 1 of the present invention is preferably inserted into a corresponding rail on the appropriate side of the trailer and placed in a suitable location for securing cargo to the trailer. Preferably, a plurality of winches 1 are used, as will be apparent to those skilled in the art. The winch 1 can be inserted into the rail by a groove or by an optional plate welded to the top of the winch 1 and by other suitable means apparent to those skilled in the art as described above.

  As an optimal embodiment of the present invention, as shown in detail in FIGS. 8 to 13, it is preferable to attach the strap 15 to the winch 1 and to anchor the strap 15 to a load fixed to the vehicle by the winch 1. Do as follows. First, the strap 15 is passed through the slit or opening of the fastening reel 13. FIG. 8 shows that the end of the strap 15 from the vehicle is inserted into a slit located between the sandwich plate 53 and the fastening reel 13, and the worm 19 of the winch 1 is preferably 1 position. As shown in detail in FIG. 9, the strap 15 is then passed through the slit of the take-up reel 29. Actually, this figure shows the winch 1 in which the end of the strap 15 is wound around a part of the tightening reel 13 and is inserted into a slit located between the rod 69 and the take-up reel 29. Is shown. These steps are generally only performed when the strap 15 is first attached to the winch 1. Preferably, the belt is further wound up by a handle (or head) on the take-up reel 29 of the winch 1, as can be easily understood from FIG. Actually, this figure shows the winch 1 in a state where the remaining portion of the strap 15 is wound around the take-up reel 29. This winding process is easily and quickly performed with a tool when the handle (or head) of the winding reel 29 is manually or preferably provided with a head (not shown) at the end of the winding reel 29. Because it can be turned, it takes much less time than what is possible with a conventional winch. Furthermore, the strap 15 can be wound up in an aligned state.

  Next, put the strap 15 on the cargo to be secured and pass it to the other side of the trailer, or attach the strap 15 to the end of the chain used to secure the cargo and attach the belt to its hook or appropriate device At the corresponding anchor point. Further, the strap 15 is securely tightened through the winch 1. FIG. 11 shows the winch 1 in a state after the tightening reel 13 is rotated to eliminate play of the strap 15 and a part of the strap 15 is fastened between the clamping plate 53 and the tightening reel 13. Yes. As can be readily understood with reference to FIGS. 14 and 15, the worm 19 of the winch 1 is then preferably moved by simply pushing the worm 19 into the hole, rotating the worm 19 and screwing it into the gear 17. 2, the strap 17 is further tightened by driving the gear 17, that is, the tightening reel 13. FIG. 13 shows the winch 1 in a state where the strap 15 is fastened to the fastening reel 13 by the worm 19 and the winding assembly 27 is pulled back to the position retracted in the horizontal direction.

  In accordance with the present invention, some of the steps described above may be reordered without affecting the proper operation of the winch 1 and without departing from the scope of the present invention, as will be apparent to those skilled in the art. Actually, for example, the step of winding the remaining portion of the strap 15 around the take-up reel 29 can be performed before or after the strap 15 is fastened to the fastening reel 13.

  Furthermore, as can be easily understood from the above, in order to wind up the portion of the strap 15 that is not used to secure the cargo with the take-up reel 29, the strap 15 is appropriately fixed and the necessary tension is applied thereto. In other words, it is only necessary to wind the fastening reel 13 only a few times according to the present invention, that is, about 2 to 4 turns around the fastening reel 13. This tightening method can prevent the winch 1 from vibrating when the vehicle moves because the winch 1 can be securely fastened to the side of the trailer when the cargo is not used to fix the cargo to the vehicle.

  The operation of the winch 1 according to the invention is also advantageous in that the strap 15 can be loosened by the worm 19 by turning it several times in a given direction, preferably counterclockwise.

  Preferably, the strap 15 can be tightened with the worm 19 by turning it several times in the direction given by its head 61, preferably in the clockwise direction. This tightening method does not require much force because the user amplifies the force applied to the crank so that the ratio of the worm 19 to the gear 17 according to the present invention becomes significant. This tightening method can also obtain a more uniform tightening on all winches 1 since the user's fatigue and physical ability (ie physical strength) are no longer important factors affecting the tightening of the strap 15.

  Preferably, as described above, it is sufficient to wind the strap 15 around the fastening reel 13 about 2 to 4 times. The winch 1 is securely fixed and takes up itself (i.e., on the clamping reel 13 rather than the majority of the strap taken up), so that the belt tension can be maintained. Actually, the portion of the strap 15 used for anchoring the load is wound up by the individual take-up reel 29, not by the fastening reel 13.

  Alternatively, a conventional socketed ratchet key can be used for tightening. Further, the key is inserted into the tightening head 59 of the tightening reel 13, and the strap 15 is tightened by operating in the clockwise direction, for example.

  As described above, the present invention is a substantial improvement over other related winches known in the prior art, and by virtue of its design and components, the winch 1 of the present invention overcomes some of the problems of the prior art. To do.

  More specifically, with respect to tightening, the winch 1 preferably uses a worm 19 that drives a gear 17. The worm 19 is preferably driven by a crank ratchet, and since the coupling ratio between the worm 19 and the gear 17 is critical, the required force is greatly reduced and virtually no longer exists. The advantages obtained from this are that the use of this type of system eliminates the risk of injury to the user of winch 1, does not require the user's physical strength to tighten, and tightening is performed on all winches 1 of the entire trailer. It becomes more uniform. Alternatively, as described above, a ratchet key with a standard socket can be used for tightening. Preferably, the key is inserted into the fastening head 59 of the fastening reel 13 and operated in the clockwise direction to fasten the load. Also preferably, when the worm 19 is turned in the corresponding release and tightening directions of the strap 15, it is automatically triggered to the corresponding first and second configurations. Preferably, once the load is tightened, the tension of the strap 15 is maintained by the gear assembly 5, and only the element of the pawl wheel 65 is provided instead as a fail-safe mechanism.

  With respect to the clamping force, the winch 1 of the present invention has a more constant clamping force than that obtained with the prior art winch, as can be easily understood from the above description and the accompanying drawings. It turns out that it is uniform. In fact, a greater clamping force can be obtained and the risk of movement of fixed loads occurring during transport can be reduced.

  With respect to maintaining the tightening tension of the fastening strap 15s, the winch 1 of the present invention is also advantageous in that the tightening tension is maintained at a pressure acting between the gear 17 and the worm 19. The advantage obtained therefrom is that the casing 21 is located in the vicinity of the fastening reel 13 and is independent of the frame of the winch 1. For this reason, for example, the ease of distortion of the winch 1 can be reduced while the trailer is retracting.

  Regarding the winding of the belt during tightening, the winch 1 of the present invention is preferably wound on the tightening reel 13 by only winding the belt about 2 to 3 times, and can provide an appropriate tension to the belt. Advantageous compared to The remaining part of the belt is wound up on the take-up reel 29. The advantage of this is that the strap 15 is less pressured by itself and the tightening force is increased, the tightening is more uniform in all of the winches 1, and the user stops the vehicle during transport and the belt It is not necessary to retighten the belt, and the wear of the belt is reduced.

  It is also recognized that the winch 1 of the present invention is advantageous over the prior art with respect to winding the belt when the winch 1 is not used to secure cargo to the vehicle. In fact, it is only necessary to wind the belt around the fastening reel 13 of the winch 1 about 2 to 4 times in order to secure the belt. Furthermore, the remaining part of the belt not used for fixing is wound up on a take-up reel by a crank. The benefits obtained from it are as follows. The quick procedure, the clamping principle that allows the winch 1 to be securely fastened to the trailer rail, and the elimination of rail wear due to vibrations that occur during the movement of the trailer.

  With respect to loosening the belt, the winch 1 of the present invention is also advantageous if the user only has to lift the pinch plate 53 and loosen the belt if the worm 19 is disconnected (ie, the first configuration). . In fact, the winch 1 of the present invention can loosen the belt with only one hand.

  The winch 1 of the present invention is also advantageously provided with an optional dynamometric socket. In fact, according to the present invention, it is possible to obtain exactly the same tightening tension for all winches 1, preferably using a crank or key with a hexagonal dynamometer socket, which is the same as that described above for conventional winches. It is impossible.

  The multi-functional tie-down winch 1 according to the present invention can be used with a flatbed trailer, or it can be used with other types of transport vehicles such as rail vehicles, maritime transport.

  The winch 1 of the present invention meets the requirements of most safety standards with respect to the use of a fixing device with a suitable loading capacity, i.e. with respect to the required number determined according to the length of the cargo to be carried and anchored. It is preferable to be provided.

  Preferably, the components of the multi-functional tie-down winch 1 of the present invention are sufficient to withstand various metallic materials such as steel or various loads envisioned for the winch 1, as will be apparent to those skilled in the art. Manufactured from other suitable materials.

  As will be apparent to those skilled in the art, the take-up reel of the winch 1 can be eliminated. In this way, winch 1 resembles a conventional winch, but still provides all the advantages of using a worm-gear assembly instead of a take-up bar.

  As will be apparent to those skilled in the art, the winch 1 can also be provided with a take-up reel locking system. In fact, instead of a toothed wheel and a latch that is fastened to the take-up reel 29 after tightening the load, it is also possible to use, for example, two rotating arms attached to the lower part inside each frame. The two rotating arms preferably serve as an aid for the clamping reel 13 and the worm-gear assembly. During tightening, the arm is rotated up by the applied force and locks the take-up reel 29 at the end of its movement.

  According to the present invention, the winch 1 can also be used as a chain vendor by hooking the hook at the end of the strap 15 to the chain and performing the same tightening procedure as described above.

  As you can now understand, the winding assembly 27 can be placed in various positions relative to the clamping assembly 3 to avoid obstacles such as chests, wheels or lights that are located under the trailer. It can be avoided.

  As will be well understood, the quick removal of the winch 1 support allows the belt to be removed from the winch 1 and, if applicable, can be adjusted as necessary. Some users may simply remove the belt to protect it from falling and / or theft.

  As will be appreciated, as briefly described herein, due to its design and components, the winch 1 of the present invention a) suffers from accidents or serious injuries associated with the use of conventional winches. B) Eliminating the risk of incurring, b) The physical strength required to operate the winch 1 is very small, making it easier for people who have recently been injured (eg, back or other body parts) to return to work, c) Since it is easy for people who do not have physical strength to enter the transportation market using flatbed trailers, for example, the doors are opened for female drivers, and d) tightening of more powerful luggage without requiring the user's physical strength. E) that a uniform winch can be obtained with all the winch 1 of the trailer, and f) that the vehicle is frequently stopped during the transportation of the cargo and the load is not retightened many times. G) The time required for tightening the load is shortened, h) the conventional chain vendor need not be used, and i) the risk of falling or shifting of the load during transportation is reduced. This increases road safety, j) reduces belt wear, k) reduces operating costs in terms of time and materials used, and l) reduces the probability of injury associated with the use of winch 1. , The owner may benefit from the reduction of insurance costs and premiums paid to the insurance companies included in the management of transportation; m) preferably provided to meet the requirements of safety standards; Thus, the present invention is a substantial improvement over prior art winches.
