Abstract

A rope tightening device (1) adapted for mounting to a length of rope (5) used when a load or loads are loaded on a truck or the like. An upper gear (4) is provided on a top surface of a projection on a casing (2), and a lower gear (10), to which a coil spring (6) is mounted, is received in the projection of the casing (2). A rope winding wheel (7) provided with a rope insertion hole (7a) is received in the casing (2), and the upper and lower gears (4, 10) are interlocked with the rope winding wheel (7). Upper and lower latching members (3, 13) adapted to latch the upper and lower gears (4, 10) are pivotally mounted on a holding shaft (3c). Therefore, even if a load or loads shake at the time of running of a truck to loose the tightening rope (5), the loosened tightening rope (5) will automatically return to its original position due to a restoring force of the coil spring (6) whereby it is wound by the rope winding wheel (7) to be tightened. Also, rotating wheels (11, 12) are provided in the casing (2), so that winding of the tightening rope (5) around the rope winding wheel (7) is smoothly effected.

Description

Description Rope fastener Technical field

The present invention relates to an improvement in a clamp for attaching to a rope used when a load is loaded on a truck or the like. Technology background

Conventionally, when loading luggage on a truck or other luggage carrier, the luggage is manually tightened several times with ropes to prevent the luggage from falling during traveling.

However, the ropes for preventing the fall of luggage are tightened manually, but the luggage swings when the truck is running, so the tightened ropes are loosened and the luggage loaded on the luggage carrier such as trucks falls on the road. There is a drawback that there is danger. Disclosure of the invention

According to the present invention, an upper gear is provided on an upper surface of a projecting portion of a case, a lower gear having a coil panel mounted therein is housed in the projecting portion of the case, and a mouth-to-wheel winding vehicle having a rope insertion hole in the case is provided. The upper and lower gears are housed in a structure in which the rope take-up truck is interlocked by a shaft, and an upper and lower locking member for locking to the upper and lower gears is rotatably attached to the holding shaft. In addition, the structure of the rope tightening device is characterized in that a rotating wheel is installed in the case. BRIEF DESCRIPTION OF THE FIGURES

FIG. 4 is a cross-sectional view of a rope fastener, and FIG. 4 is a rope fastener according to the present invention. FIG. 5 is a cross-sectional view showing a state in which the rope is tightened by the applicator, and FIG. 5 is a longitudinal sectional view showing a state in which the rope is tightened by the rope tightener according to the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

Next, the incinerator according to the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a state in which the rope tightening device of the present invention is attached to a rope for tightening a load. The tightening rope 5 for tightening a load is a rope tightening device 1 of the present invention. , 1 are attached, and one end of the tightening rope 5 passed through the rope tightening device 1 is tied to the hooks 14, 14, 14 provided on the cargo bed.

FIG. 2 is a front view of the rope tightening device of the present invention.The rope tightening device 1 is attached to a case 2 having a projection 2a in which an upper gear 4 is housed and a holding shaft 3c. And upper and lower locking members 3, 13; upper and lower gears 4, 10; a coil panel 6;

On the surface of the case 2 of the lower gear 10 housed in the case 2b, there is a holding shaft 3c holding the upper locking member 3 and the lower locking member 3d. Upper and lower locking members 3, 13 are rotatably attached to 3c. A coil spring 3b is mounted on the holding shaft 3c, and the locking members 3, 13 are constantly moved by the coil spring 3b so that the distal end portions 3a, 13a of the upper and lower locking members 3, 13 are provided. Are the projections 4b of the upper gear 4 and the projections 10b of the lower gear 10 and the projections 4b of the upper gear 4 and the projections 10b of the lower gear 10 formed with the locking grooves 4a, 10b. It gets into a, preventing the upper and lower gears 4, 10 from rotating in the direction of arrow a. Reference numeral 5 indicates a fastening rope.

FIG. 3 is a partial cross-sectional view of the rope tightening device according to the present invention, and an upper gear in which a fitting groove 4 a and a locking projection 4 b are formed in a protruding portion 2 a of a case 2. 4 force As described above, it is fixed and housed on the shaft 8.

The lower gear 10 having the locking projection 10a and the fitting groove 10b formed on the outer peripheral surface is attached to the shaft 8 to which the upper gear 4 is fixed. Lower gear 1 A coil spring 6 is mounted in 0, one end of the coil spring 6 is fixed to the shaft 8, and the other end 6a is fixed to the inner peripheral surface of the lower gear 10. FIG. 4 is a partial cross-sectional view of the rope tightening device of the present invention, showing a state in which the tightening rope is tightened, and FIG. 5 is a longitudinal sectional view of the rope tightening device of the present invention. When the fastening rope 5 is loosened, the winding wheel 7 around which the fastening rope 5 is wound rotates due to the restoring force of the coil panel 6, and the fastening rope 5 is wound around the rope winding vehicle 7. The upper gear 4 and the lower gear 10 rotatably mounted on the shaft 8 on the case 2 and the projection 2a do not rotate in the direction of arrow b.

This is because the distal ends 3a, 13a of the locking members 3, 13 are fitted into the fitting groove 4a formed in the upper gear 4 and the fitting groove 10a formed in the lower gear 10. This is because the upper gear 4 and the lower gear 10 are prevented from rotating in the direction of arrow b. The rope winding vehicle 7 has an insertion hole 7a through which the fastening rope 5 can be inserted, and the fastening rope 5 is inserted through the insertion hole 7a.

FIG. 5 is a longitudinal sectional view of the rope fastener according to the present invention, and the operation of the rope fastener according to the present invention will be described with reference to the figure.

First, the front end of the fastener 9 is fitted into the fitting groove 4a formed in the head of the shaft 8, and the rear ends 3d, 13d of the upper and lower locking members 3, 13 are finger-pointed. And the projections 4b, 10 & and the projections 4 1), 10 on the outer peripheral surfaces of the upper and lower gears 4, 10. Remove from the locking grooves 4c, 10b formed between a, and rotate the clamp 9 in the clockwise direction while rotating so that the coil spring 6 is wound, and the coil spring 6 is tightened. After that, the tightening rope 5 is inserted into the tightening rope insertion hole 7 a formed in the winding vehicle 7, and one end of the tightening rope 5 is connected to the hooks 14, 1 provided on the truck bed. 4. Attach the rope clamp 1 as shown in Fig. 1.

Then, when the luggage swings while the truck is running and the tightening rope 5 wrapped around the rope winding vehicle 7 that winds up the tightening rope 5 in the case 2 b is loosened, it is wound. To return to the original position by the restoring force of the coil spring 6 The rope 5 is wound around the rope take-up vehicle 7 and the loosened rope 5 is tightened. Reference numerals 11 and 12 indicate rotating wheels. By installing the rotating wheels 11 and 12, the tightening rope 5 is not broken and cut by friction, and the rope winding of the tightening rope 5 is prevented. Take-up to take-up 7 becomes smooth. Industrial applicability

Since the present invention is a rope tightening device having the above-described configuration, even if the rope tightening the load loosened during traveling of the truck, the loosened rope is automatically tightened, so that the load may fall. The effect of not being obtained is obtained.
