Description

[Detailed description of the invention] Industrial field of application The invention relates to a belt stopper that can pull the belt in the tightening direction, but cannot loosen it unless a special operation is performed. When securing objects to the cargo bed of a car, motorcycle, etc., as well as fasteners for car seat belts, etc.
It can be used for fixing, bundling, etc. relatively heavy objects.

Conventional technology Conventionally, this type of belt stopper was
There have been various devices, such as No. 8745, that can tighten a belt with a small tightening force, but there has never been one that can secure a strong tightening force with a small device.

Problems to be Solved by the Invention The present invention is an attempt to solve the above-mentioned problems, and is an attempt to obtain a belt stopper that can ensure a strong tightening force with a small device.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A belt pressing tool is rotatably supported by a fixed shaft between both side walls of an outer frame having a U-shaped cross section, and an upper frame having a U-shaped cross section is rotatably supported by the belt pressing tool by a support shaft. The belt can be fixed by pressing between the pressing part and the inner surface of the upper frame by covering the pressing part of the belt pressing tool and forming the pressing part in a position biased to one side with respect to the axis connecting the fixed shaft and the support shaft. The upper frame is positioned so as to be able to abut against the inner surface of the top plate on the outer frame when tightening the belt.

Function Since the present invention is configured as described above, the belt is inserted between the upper frame having a U-shaped cross section and the pressing part of the belt pressing tool from a direction biased to the other side of the axis connecting the fixed shaft and the support shaft. When inserted, the belt presses the pressing part in the direction away from the inner surface of the upper frame, and the belt can be freely inserted and an appropriate object to be fastened can be fastened. After this tightening is completed, if the tension on the belt in the tightening direction is released, the belt will try to recover by its own restoring force, the restoring force of the object to be tightened, etc. Due to the frictional force, the pressing portion is pulled in the axial direction connecting the fixed shaft and the support shaft, and strongly presses the belt against the inner surface of the upper frame.
This pressure becomes stronger as the restoring force of the belt becomes stronger, but when the restoring force of the belt is strong, the upper frame also rotates in the axial direction using the support shaft as a fulcrum, and the upper frame is moved to the top of the outer frame. Since it is pressed against the inner surface of the plate, even if a strong restoring force is applied to the belt, the upper frame is firmly pressed and fixed to the inner surface of the top plate of the outer frame, and can sufficiently withstand the strong restoring force of the belt.

In addition, in order to remove the belt from the pressing part, if the upper frame is pressed in the above-mentioned axial direction, the pressing engagement relationship between the pressing part and the upper frame via the belt is also loosened, so that the belt can be easily removed. It is possible.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an outer frame, and both sides of a top plate 2 are bent to provide side walls 3 and 4 to form a U-shaped cross section. Between these side walls 3 and 4, a belt pressing tool 5 formed in an inverted L shape is rotatably fixed with a fixed shaft 6,
On the outer surface of one side of the L-shape of the belt pressing tool 5, unevenness for engaging the belt 7 is provided to form a pressing portion 8. An upper frame 1 having a U-shaped cross section is attached to this belt pressing tool 5.
0 is rotatably supported by a support shaft 11, and the upper frame 10 covers the pressing part 8, and the pressing part 8 is biased to one side with respect to the axis 9 connecting the fixed shaft 6 and the support shaft 11. The belt 7 can be fixed by pressing between the pressing portion 8 and the inner surface of the upper frame 10. The upper frame 10 is positioned so that its upper edge 12 can abut against the inner surface of the top plate 2 of the outer frame 1 when the belt 7 is tightened due to its restoring force. A horizontal bar 14 for pressing the upper frame 10 in the tightening release direction of 7.
is fixed. Further, a lower frame 16 is fixed to a part of the opening 15 of the outer frame 1 at a position facing the top plate 2, and a piece of a coil spring 17 wound around the fixed shaft 6 is engaged with the lower frame 16. By engaging the other piece of the coil spring 17 with the inner surface of the pressing portion 8 of the upper frame 10, the pressing portion 8 is urged to press against the inner surface of the upper frame 10.

In the configuration as described above, between the upper frame 10 having a U-shaped cross section and the pressing portion 8 of the belt pressing tool 5,
From the belt insertion opening 13 provided at a position biased to the other side of the axis 9 connecting the fixed shaft 6 and the support shaft 11,
When the belt 7 is inserted in the direction of arrow B, the belt 7 presses the pressing portion 8 in a direction away from the inner surface of the upper frame 10, and the belt 7 can be inserted freely. This insertion can be carried out more easily by pressing the horizontal bar 14 in the direction of the belt pressing tool 5, and can be used for securing luggage to the cargo bed of a car, motorcycle, etc., tightening a seat belt, etc.
Appropriate fastening objects can be fastened.

After this tightening is completed, if the tension on the belt 7 in the tightening direction is released, the belt 7 will try to recover due to its own restoring force, the restoring force of the object to be tightened, etc. Due to the accompanying frictional force, the pressing part 8
is pulled in the direction of the axis 9 connecting the fixed shaft 6 and the support shaft 11, and strongly presses the belt 7 against the inner surface of the upper frame 10. The stronger the restoring force of the belt 7, the stronger this pressing becomes. However, when the restoring force of the belt 7 is strong, the upper frame 10 also rotates in the direction of the axis 9 using the support shaft 11 as a fulcrum, Since the upper frame 10 is pressed against the inner surface of the top plate 2 of the outer frame 1, even if a strong restoring force is applied to the belt 7, the upper frame 10 is firmly pressed and fixed to the inner surface of the top plate 2 of the outer frame 1, and the belt It can withstand the strong restoring force of 7.

Further, in order to loosen the belt 7 or remove it from the pressing part 8, by pressing the horizontal bar 14 of the upper frame 10 in the direction of the axis 9, that is, in the direction of arrow B, the pressing part 8 and the upper frame 10 are Since the pressing engagement relationship via the belt 7 is also loosened, the belt 7 can be easily removed.

Effects of the invention Since the present invention is configured as described above, it is extremely easy to insert the belt between the upper frame and the pressing part of the belt pressing tool, and it is possible to easily tighten the appropriate object. can be worn. After this tightening is completed, as the belt and the object to be tightened are restored,
Due to the frictional force between the belt and the pressing part, the pressing part strongly presses the belt against the inner surface of the upper frame, and if the restoring force of the belt is strong, the upper frame also rotates in the above-mentioned axial direction using the support shaft as a fulcrum. However, since the upper frame is pressed against the inner surface of the top plate of the outer frame, even if a strong restoring force is applied to the belt, the upper frame will be firmly pressed and fixed to the inner surface of the top plate of the outer frame, and the strong restoring force of the belt will be sufficient. It becomes bearable. Therefore, it is possible to secure a strong tightening force with a small device, and it can be used to secure objects to the cargo bed of cars, motorcycles, etc., as well as fasteners for car seat belts, etc.
It can be used for fixing, binding, etc. relatively heavy objects.
