DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoulder pad for holding a business-use video camera by holding it on a shoulder, and more particularly, to a shoulder pad comprising three members of a skin, a fluid such as powder, and a bone member. By constructing from
In addition to being durable and durable, the fitting to the shoulder is improved with good stability, and each component can be separated so that it can be reused.

[0002]

2. Description of the Related Art Conventionally, a handy-type professional video camera is relatively heavy, and therefore, the video camera is provided with a shoulder pad having a cushioning property for a photographer to carry on a shoulder to take a picture. .

FIG. 10 is a side view of a professional video camera, and FIG. 11 is a partially cutaway perspective view of a shoulder pad. This type of video camera is provided with a shoulder pad 50 on the bottom surface of the main body 1 and is made of a member having cushioning properties.

[0004] In general, a urethane foam material is foam-formed as a conventional shoulder pad, and a skin 5 as a surface material is formed.
0a and the inner cushion 50b are integrally molded. Also, during foam molding of the shoulder pad, an aggregate 51 such as a metal material is insert-molded, and the aggregate 51 is screwed into the main body 1 of the video camera from a recess 52 formed in a part of the shoulder contact surface of the shoulder pad. It is fixed by screwing.

[0005]

By the way, if such a shoulder pad is set to be soft enough to fit the shoulder 50a by increasing the flexibility of the skin 50a, the skin 50a
However, there is a problem that the durability of the device is impaired. In addition, the number of defects of the skin 50a at the time of molding increases, which causes a reduction in product yield.

In order to increase the durability of the skin 50a,
If it is molded harder, the fit to the shoulder is impaired. In addition, since the surface of the skin made of urethane foam is slippery, there is a problem that the holdability on the shoulder is not good.

[0007] Furthermore, the shoulder pad on which the aggregate 51 is insert-molded makes it difficult to separate the components when collecting the components, so that the resources cannot be reused.

Therefore, the applicant of the present invention proposed a shoulder pad of a video camera for solving the above-mentioned problems in Japanese Patent Application No. 9-318410. This shoulder pad has a skin that is shaped in the form of a shoulder pad having an outer surface that is less slippery and has flexibility and durability, and a cushion material made of urethane foam that is shaped in the shape of the skin and that has a low deformation rate with respect to external pressure. ,
And a bone member which retains the shape of the shoulder pad and is screwed to the camera body.

The shoulder pad thus configured is
The video camera can be stably held without the shoulder pad slipping from the shoulder, and the elastic deformation of the cushioning material gives a familiar feeling to the shape of the shoulder. Moreover, since the outer skin, the cushioning material, and the bone member are separable, there is a feature that separation at the time of component collection is easy and resources can be reused.

However, when urethane foam is used as the cushioning material, the cushioning material is deformed by the movement of the shoulder during video shooting even after the shoulder pad is placed on the shoulder, and the fit feeling is somewhat unstable. There was a problem that remained. Further, a cushion material using urethane foam may harden when used in a cold region or the like, and in this case, the cushioning property is impaired, and the function as a shoulder pad may be reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and further improves the sense of stability when a shoulder pad is placed on a shoulder. The aim is to obtain an unaffected video camera shoulder pad.

[0012]

In order to achieve the above object, a shoulder pad of a video camera according to the present invention comprises:
The outer surface is made of a skin that is non-slip and has flexibility and durability. This skin contains a fluid such as powder or gel, and holds the skin and separates it for screw fixing to the camera body. With a possible bone member.

[0013] With this configuration, the fluid can move freely with respect to the external pressure applied to the epidermis. Therefore, when the shoulder pad is placed on the shoulder, the fluid is moved and the epidermis is moved. The shape is deformed along with the shape, and the deformed shape does not lose its shape, and the state of being fitted to the shoulder can be maintained. Further, since the fluid does not harden or solidify in a low temperature environment, the flexibility of the shoulder pad is not impaired in a cold region or the like.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a shoulder pad of a video camera according to the present invention will be described with reference to the drawings.

[First Embodiment] FIG. 1 is a side view of an entire professional video camera according to this embodiment, FIG. 2 is a plan view of a shoulder pad, and FIG. 3 is a sectional view taken along line AA of FIG. 4 is a cross-sectional view taken along the line BB, and FIG. 5 is a perspective view of the separated state of the epidermis and the aggregate.

The shoulder pad 2 includes a skin 3, a fluid 4 contained in the skin 3, and an aggregate 5 for fixing the shoulder pad 2 to the video camera body 1.

Hereinafter, details of each of the above-described constituent members will be described. The outer skin 3 constitutes the outer skin of the shoulder pad 2, and is formed from, for example, soft vinyl chloride, a rubber material, synthetic leather, or the like, which is hard to slip and has flexibility and durability. The method for forming the skin 3 is performed by rotational molding or other blow molding, and the outer shape of the shoulder pad 2 is kept in a bag shape.

A rectangular opening 6 is formed on the upper surface (the surface in contact with the video camera body 1) of the skin 3 thus formed, and screws are formed on both side edges of the opening 6. A plurality of small holes 7 to be inserted are formed. Also,
An elongated hole-shaped protruding recess 8 is formed substantially at the center of the bottom of the epidermis 3 (the surface that contacts the shoulder of the cameraman). The concave portion 8 reaches the opening 6 of the skin 3, and small holes 8a, 8a through which screws are inserted are formed in this surface portion.

The fluid 4 is, for example, a flour-like powder. For example, the fluid 4 is made of a plastic material, carbon, or the like in the form of powder (about several μm to several tens μm), and is hardened (solidified) in a low-temperature environment. Is used that does not produce

The fluid 4 is, as another example, a relatively viscous gel, for example, silicone oil or fat. In the case of a gel, a gel that does not coagulate in a low temperature environment is used.

On the other hand, the aggregate 5 is made of a petitstick material or a metal sheet metal, and has two lower bone plates 10 and 11 housed in the skin 3 and lower bone plates 10 and 11 from above the skin 3.
And an upper bone plate 12 to be assembled with the upper bone plate 12.

The lower bone plates 10 and 11 are the shoulder pads 2
And flat portions 10a, 11a positioned corresponding to the opening 6 of the skin 3, and a curved surface inserted along the back surface of the skin 3 to maintain the shape of the skin 3. It has parts 10b and 11b. Also, the flat portions 10a, 11a
A notch 10 which escapes the raised recess 8 of the epidermis 3
c, 11c, and a plurality of bolts 13, 13 are erected on both flat portions 10a, 11a.

The upper bone plate 12 is a flat plate which is assembled in correspondence with the flat portions 10a, 11a of the lower bone plates 10, 11.
Holes 12a into which the above-mentioned bolts 13 are inserted are formed on both side edges. Further, a hole 12b is formed in the center of the skin 3 so as to correspond to the small holes 8a, 8a of the recess 8 of the skin 3.

Next, the procedure for assembling the shoulder pad 2 will be described with reference to FIGS. First, the fluid 4 is accommodated through the opening 6 in the skin 3 shown in FIG. 6 formed by rotational molding or the like. At this time, the fluid 4 is almost completely filled in the skin 3 regardless of whether it is a powder or a gel.

After the filling of the fluid 4, the two lower bone plates 10, 11 on the front side and the rear side are inserted into the upper back surface of the epidermis 3 respectively (see FIG. 7), and the two bone plates 10, 11 Each bolt 13 is inserted into the small hole 7 of the skin 3. Then, the holes 12a of the upper bone plate 12 are passed through the bolts 13 so that the upper bone plate 12 is overlaid on the skin 3, and the nuts 14 are attached to the bolts 13.
(See FIG. 3). Thereby, the opening 6 of the epidermis 3 is formed by the lower bone plates 10 and 11 and the upper bone plate 12.
Of the bone plates 10 and 11 and the epidermis 3 can be integrated. Further, the shape of the entire shoulder pad 2 does not lose its shape due to the attachment of the two bone plates 10 and 11.

Thus, the shoulder pad 2 assembled as described above is attached to the concave portion 1a formed at the bottom of the video camera main body 1, and the concave portion 8 of the skin 3 is formed.

Since it is closed by 11 and the upper bone plate 12, it is sealed so that the gel-like body does not leak from the gap between these bone plates.

The shoulder pad according to the present invention thus configured has a very high degree of freedom when the video camera is carried on the shoulder by the cameraman by filling the fluid 4 in the skin 3. Therefore, it is possible to precisely move along the shape of the shoulder of the photographer, and to maintain the state deformed to the shape of the shoulder. As a result, there is no feeling of instability as in the case of using the conventional cushioning material, so that it is possible to stably fit the shoulder, and the video camera can be stably carried on the shoulder, and also for a long time. There is no burden on the shoulders when shooting video. Further, even when the shoulder pad is used for a long time, the pad function such as the cushioning material does not deteriorate.

Further, the use of the skin 3 which is less slippery and has good flexibility and durability ensures that when the cameraman carries the video camera on his shoulder, the shoulder pad does not slip from the shoulder and the stability is good.

Further, since the fluid 4 does not harden or solidify even in a low temperature environment, the deformation speed of the fluid 4 does not decrease even in video shooting in a cold region or the like. There is no loss in pad flexibility.

Incidentally, even if the center of gravity of the entire video camera moves due to the difference in the weight of the lens of the video camera, as shown in FIG. 1, the shoulder pad 2 moves the fluid 4 as indicated by the dotted line depending on the position where the shoulder hits. The deformed part is 2a or 2b
Because it can be changed freely like this, it becomes a shoulder pad that is very easy for the photographer to carry,
Video shooting becomes extremely easy.

Further, the shoulder pad of the present invention has a screw 1
5 can be removed from the video camera main body 1, and by removing the nut 14, the shoulder pad 2 can be separated from the skin 3, the fluid 4, and the upper and lower bone plates 1.
Since the shoulder pad 2 can be separated into 0, 11 and 12, the shoulder pad 2 can be easily separated at the time of component recovery, and as a result, resources can be reused.
