Description

The present invention relates to a fixing device, and more particularly to a fixing device for fixing a device to a long object.

Conventionally, cameras such as video cameras and digital cameras capable of shooting moving images have been provided. Further, in recent years, the recording medium has changed from magnetic tape or disk to semiconductor memory, and due to the drastic miniaturization and large capacity of semiconductor memory, lightweight and compact cameras capable of shooting moving images for a long time have rapidly become widespread.

Using these cameras, for example, fixing the camera to the handlebar of a bicycle using a fixing device, shooting a video image while driving, and playing the video image later to enjoy it. Is coming to be done.

However, while the bicycle is running, it receives vibration due to unevenness of the road surface and impact when overcoming a step, and the fixing device needs to have sufficient grip force to withstand this vibration and impact. Therefore, in order to firmly fix such a fixing device to a handle or the like, a large force is required for tightening. For these reasons, a fixing device that can obtain a strong grip force even with a light force has been desired.

In addition, there is a demand for a fixing device that allows the same camera to be used even when going by bicycle. In other words, the camera is fixed to the fence of the park or the pipe of the playset where you went, and the pipe is thicker than the pipe such as the handle of the bicycle so that you can take a commemorative photo with yourself or your friends. There has been a demand for a fixing device that can be stably fixed in response to the above.

As these conventional fixing devices, there is one disclosed in Patent Document 1. This fixing device is a belt-type camera stand in which a base with screws for fixing a camera is provided on a fixing belt and an adjuster is attached. Then, when taking a picture with a camera, the shape of a fence, a handlebar of a stroller, a frame of a bicycle, a playset in a park, or the like can be attached to and fixed to a rod-shaped object without a tripod.

Further, as these conventional fixing devices, there is one disclosed in Patent Document 2. This fixing device has a base member made of a metal plate that is bent at the center and has a mounting surface for pipe material on the bent inner part and a pan head mounting surface on the outer part, and a clamp mechanism for mounting the pan head. It is equipped with a camera platform mounted on the surface. Then, the camera can be easily and quickly installed on the pipe material.

Further, as these fixing devices, the fixing device shown in FIG. 15 is generally known. The fixing device 1001 is made of highly rigid metal, and the camera 1110 is fixed to one end 1003 of the fixing device main body 1002 so that the camera 1110 can be fixed to the pipe 1210 by using the other end 1004 and the fixing piece 1005. Is. The rubber sheet 1006 is first wound around the pipe 1210, and then the pipe 1210 is sandwiched between the other end 1004 and the fixing piece 1005, and the two screws are tightened with the handle 1007. In this way, the camera 1110 can be fixed to the pipe 1210 via the fixing device 1001.

However, with the technique described in Patent Document 1, when vibration or impact is applied, such as when a bicycle is run, the grip force is not sufficient and the shooting with the camera becomes unstable. There was an inconvenience.

Further, in the technique described in Patent Document 2, since the long object is directly gripped by using the metal fittings, it is possible to fix the long object only in several places on the outer circumference of the long object with a strong force. However, there was an inconvenience that the grip force against vibration and impact was not strong. In addition, there is a disadvantage that the diameter range of the pipe to be attached is narrow.

Further, the technique shown in FIG. 15 has a disadvantage that the mounting is complicated, the tightening screw needs to be tightened firmly, and the mounting requires time and a large force. In addition, there is a disadvantage that the diameter range of the pipe to be attached is narrow.

By allowing the camera 110 to be screwed into the tripod screw hole, the camera 110 is fixed to the device fixing base 2.

As shown in FIG. 5, a square recess 7b is provided in a substantially central portion of the lower surface 7a of the device fixing base 2, and a pressure-welded rubber leg connecting portion 7 is configured. Here, the lower surface 7a is composed of two surfaces 7c and 7d having a slightly protruding central portion downward, which looks like a shallow substantially V-shape when viewed from the side surface. As shown in FIG. 4, the recess 7b is formed so that the lower surface of the dial 11 is closed by tightening the upper portion of the square through hole formed in the substantially central portion of the lower portion of the device fixing base main body 10.
Further, as shown in FIGS. 4 and 5, wide through holes 8a and 8b penetrating the lower parts of the front surface and the rear surface of the device fixing base 2 are provided to form the tightening belt mounting portion 8.

As shown in FIGS. 2 to 5, the pressure-welded rubber legs 3 have a predetermined width, and have a substantially inverted Y-shaped and symmetrical shape with an open leg angle of about 80 to 90 degrees when viewed from the side surface. None, it is integrally molded with a flexible material such as rubber, such as urethane rubber. A wide square convex portion 13b protrudes from the center of the upper surface 13a of the upper portion of the pressure contact rubber leg 3, and a wide through hole 13c is provided in the convex portion 13b in the front-rear direction to form a device fixing base connecting portion 13. Here, it is composed of two surfaces 13d and 13e having a slightly recessed central portion downward, which looks like a shallow substantially V-shape when viewed from the side surface of the upper surface 13a.

As shown in FIG. 5, the bifurcated lower portion of the pressure contact rubber leg 3 forms the pressure contact portion 14. Each branched pressure contact portion 14 is separated by a substantially V-shaped groove from the outer surface side, and is a portion near the root that branches into two branches and has a first predetermined thickness, and a base pressure contact portion 14a and a base portion. It is composed of two auxiliary pressure-welding portions 14c connected by a thin-walled portion 14b from each end of the pressure-welding portion 14a and having a second predetermined thickness. The two auxiliary pressure welding portions 14c are connected by a thin portion 14b. Here, the inner surface side of the pressure contact portion 14 is formed in a continuous substantially planar shape.

It is composed. The buckle portion 4b has a square frame shape and is fixed to one end of the belt portion 15. The other end of the belt portion 4a is inserted into the buckle portion 4b, folded back, and the hook-and-loop fasteners are overlapped and engaged with each other. Here, since the belt portion 4a is folded back and pulled, the tightening belt 4 can be tightened with a strong force by the principle of the moving pulley.
As shown in FIG. 2, dots are arranged on the surface on which the engaging element is located in order to clarify which surface of the belt portion 4a has the engaging element. The same applies to the drawings after FIG. 2.

How to assemble the device fixing base 2, the pressure contact rubber leg 3, and the tightening belt 4 will be described with reference to FIG. As shown in FIG. 5, first, the convex portion 13b of the device fixing base connecting portion 13 is aligned with the concave portion 7b of the pressure contact rubber leg connecting portion 7 on the device fixing base 2 so that the directions of the through holes 8a and the through holes 13c are aligned. , Insert and connect. In this state, the through hole 8a of the tightening belt mounting portion 8 and the through hole 13c of the device fixing base connecting portion 13 form a communication through hole 15 that penetrates each other. Then, as shown in FIG. 5, the assembly is completed by passing the other end of the belt portion 4a through the communication through hole 15. Therefore, the fixing device 1 can be easily assembled and the number of parts is small.

Here, as shown in FIG. 6, the size of the communication through hole 15 is such that the belt portion 4a in a state where the engaging element is provided on one surface and is raised is movable but does not easily come off. It is formed in the belt.

Further, as shown in FIG. 5, the lower surface 7a of the pressure-welded rubber leg connecting portion 7 is composed of two surfaces 7c and 7d having a slightly protruding central portion downward, and the upper surface 13a of the pressure-welded rubber leg 3 is also similarly. Since it is composed of two surfaces 13d and 13e whose central portion is recessed downward, when assembled, the two surfaces are positioned so as to overlap each other and align their centers in the front-rear direction with each other. Then, when the device fixing base 2 is pressed against the pressure contact rubber leg 3 by the tightening belt 4, the pressure contact rubber leg 3 is pressed by the device fixing base 2 without shifting the positions in the front-rear direction of each other.

The operation of the parts constituting the fixing device 1 when the fixing device 1 is wound around the long object 200 will be described below with reference to FIGS. 1 to 9.

As shown in FIG. 7, when the long object 200 is a small diameter pipe 210 having a smaller diameter than the open leg angle of the pressure contact rubber leg 3, the open leg of the pressure contact rubber leg 3 is narrowed to reduce the diameter of the small diameter pipe 210. It is pressure-welded so as to wrap around the outer circumference. That is, when the tightening belt 4 is tightened, the device fixing base 2 is pressed downward and the base pressure contact portion 14a is pressed against the small diameter pipe 210, and the base pressure contact portion 14a protrudes from the lower part of the device fixing base 2. The outer surface is pressed by the tightening belt 4 and deformed, and is pressed against the small diameter pipe 210.

As shown in FIGS. 1 and 7, the outer surface of the auxiliary pressure contact portion 14c is pressed by the tightening belt 4 and bent at the thin portion 14b, and at the same time, the auxiliary pressure contact portion 14c is deformed and pressure contacted along the outer surface of the small diameter pipe 210. At this time, since the auxiliary pressure contact portion 14c has a second predetermined thickness and its cross-sectional shape is formed into a substantially triangular shape or a substantially trapezoidal shape, the tightening belt 4 is used from the tip portion of the auxiliary pressure contact portion 14c. It is crushed and crimped.

As shown in FIGS. 1 and 7, simply by applying the fixing device 1 to the small diameter pipe 210 and tightening the tightening belt 4, the outer surface of the pressure contact rubber leg 3 is pushed, and the outer circumference of the small diameter pipe 210 is approximately 4 minutes. Wrap around a wide range of 3 angles. That is, since the pressure contact portion 14 is wound over a half circumference of the outer circumference of the small diameter pipe 210, the fixing device 1 obtains a strong grip force.

As shown in FIGS. 1 and 7, the pressure contact rubber leg 3 has a base pressure contact portion 14a and an auxiliary pressure contact portion 14c, and in addition to the pressure contact by the base pressure contact portion 14a, the auxiliary pressure contact portion 14c also has a small diameter pipe 210. It is pressed against the outer circumference. That is, the base pressure-welding portion 14a and the auxiliary pressure-welding portion 14c of the pressure-welding rubber leg 3 share each of the pressure-welding portions 14a over a wide angle of the outer circumference of the small-diameter pipe 210, and the inner surface of the pressure-welding portion 14 is continuously and strongly pressure-welded. A strong grip can be obtained.

As shown in FIGS. 1 and 7, the inner surface of the pressure-welded rubber leg 3 is formed in a continuous substantially flat shape including the thin portion 14b, and is continuous with the small-diameter pipe 210 having a smooth outer surface over a wide area. The grip is even stronger because it is in close contact with the rubber.

Further, as shown in FIGS. 1 to 7, when the fixing device 1 is applied to the small diameter pipe 210, the pressure contact portion 14 of the pressure contact rubber leg 3 has a substantially inverted Y shape, so that the bifurcated portion serves as a guide. , Centering can be done just by placing the fixing device on a long object. Further, when the tightening belt 4 is tightened, the tightening belt 4 can be smoothly bent along the outer circumference of the small diameter pipe 210, and the tightening belt can be tightened as it is. That is, the fixing device 1 can be easily and quickly attached to the small diameter pipe 210 long object.

Here, in FIG. 1, the position of the buckle portion 4b of the tightening belt 4 is set to the front, but since the belt portion 4a is configured to be movable in the communication through hole 15, it can be arbitrary such as rearward or downward. The buckle portion 4b can be arranged there. Further, the belt portion 4a can be inserted from the opposite direction of the communication through hole 15. That is, the buckle portion 4b can be arranged and tightened with respect to the long object 200 in a direction and a direction in which it is easy to tighten.

Next, as shown in FIG. 8, when the long object 200 is a large-diameter pipe 220 having a diameter larger than the opening angle of the pressure-welded rubber leg 3, the open leg of the pressure-welded rubber leg 3 is widened. It is pressure-welded so as to wrap around the outer circumference of the large-diameter pipe 220. That is, when the tightening belt 4 is tightened, the device fixing base 2 is pressed downward, and the base pressure contact portion 14a spreads its open legs and is pressed against the large diameter pipe 220.

As shown in FIG. 8, the outer surface of the auxiliary pressure-welding portion 14c is pressed by the tightening belt 4 and slightly bent at the thin-walled portion 14b, and is deformed and pressure-welded along the outer surface of the large-diameter pipe 220. At this time, the cross-sectional shape of the auxiliary pressure contact portion 14c is formed into a substantially triangular shape or a substantially trapezoidal shape, and is crushed and crimped from the tip portion of the auxiliary pressure contact portion 14c by the tightening belt 4.

As shown in FIG. 8, since the pressure-welded rubber legs 3 are pressure-welded to the large-diameter pipe 220 having a smooth outer surface over a wide area of the inner surface, the fixing device 1 is stably fixed corresponding to the large-diameter pipe 220. Further, a stronger grip force can be obtained by increasing the number of auxiliary pressure contact portions 14c so as to wrap the large-diameter pipe 2 over a wide angle of the outer circumference, for example, over a half circumference of the outer circumference. In this case, a large number of auxiliary pressure-welding portions 14c of the pressure-welding rubber legs 3 are provided from the beginning, and the user appropriately cuts off the excess auxiliary pressure-welding portions 14c according to the size of the outer circumference of the long object 200. May be good.

Here, since the outer circumference of the large-diameter pipe 220 is large, one tightening belt 4 is insufficient. Therefore, as shown in FIG. 8, the two tightening belts 4 are connected and tightened to be fixed. The connection of the tightening belt 4 is extremely easy because the other end of the one belt portion 4a is simply inserted into the other buckle portion 4b, folded back and engaged. By preparing a plurality of tightening belts 4 in this way, it is possible to cope with a large outer circumference of a long object.

As shown in FIG. 9, when the fixing device 1 is attached to the substantially flat portion of the square lumber-shaped member 230 having a square cross section, the pressure-welded rubber legs 3 are widely opened and pressed against the flat surface portion of the square lumber-shaped member 230. NS. Further, since one tightening belt 4 is insufficient, three tightening belts 4 are connected and used here.

As shown in FIG. 9, when tightened by these three tightening belts 4, the equipment fixing base 2 is pressed downward, and the base pressure contact portion 14a is further opened and pressed against the square lumber-like member 230. Then, the auxiliary pressure-welding portion 14c is bent outward at the thin portion 14b between the base pressure-welding portion 14a and the auxiliary pressure-welding portion 14c. The outer surface of the auxiliary pressure contact portion 14c at the end is pressed by the tightening belt 4 and is pressed against the flat surface portion of the square lumber-like member 230.
