[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shoulder pad for holding and holding a commercial video camera on a shoulder, and more specifically, the shoulder pad is composed of three members, an epidermis, a cushion material, and a bone member, so that it is difficult to slip and is durable. In addition to improving the fit to the shoulder, each component can be separated and reused.
[0002]
[Prior art]
FIG. 11 shows a side view of the professional video camera, and FIG. 12 shows a perspective view of the shoulder pad.
This type of video camera is provided with a shoulder pad 50 on the bottom surface of the main body 1, and the shoulder pad 50 is made of a member having a cushioning property so that a cameraman can shoot a relatively heavy video camera on the shoulder. Yes.
[0003]
In general, there is a conventional shoulder pad produced by foaming a urethane foam material and integrally molding a skin 50a and an internal cushion 50b as a surface material. When foaming the shoulder pad, an aggregate 51 such as a metal material is insert-molded, and the aggregate 51 is attached to the main body 1 of the video camera with a screw 53 from a recess 52 formed in a part of the shoulder pad surface of the shoulder pad. It is fixed by screwing.
[0004]
[Problems to be solved by the invention]
By the way, when such a shoulder pad is set to be soft enough to enhance the flexibility of the skin 50a and fit the shoulder, there is a problem that the durability of the skin 50a is impaired. In addition, the defects of the skin 50a at the time of molding increase and the product yield also decreases.
[0005]
In addition, if the skin 50a is molded hard in order to enhance the durability of the skin 50a, the fit to the shoulder is impaired. Moreover, since the surface of the skin formed of urethane foam is slippery, there is a problem that the holdability to the shoulder is not good.
[0006]
Furthermore, since the shoulder pad in which the aggregate 51 is insert-molded becomes difficult to separate at the time of parts collection, it is impossible to reuse resources.
[0007]
The present invention has been made to solve the above-described problems, and when a cameraman carries a video camera, the shoulder pad is less slippery, and the fit can be improved and the durability can be enhanced. An object of the present invention is to obtain a shoulder pad of a video camera in which each component can be separated and reused.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the shoulder pad of the video camera according to the present invention is composed of a skin whose outer surface is hard to slip and has flexibility and durability, and a cushion material whose deformation speed is slow against the external pressure is accommodated in the skin. And a separable bone member for screw fixing to the camera body.
[0009]
By being configured in this manner, it is possible to select and use a skin member that is not slippery and has flexibility and durability as a skin, so that the fit of the shoulder pad to the shoulder can be improved, and the appearance and Durability can be increased. Further, since the epidermis, the cushion material, and the bone member are separable, it is possible to separate them when they are discarded, so that resources can be reused.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a shoulder pad of a video camera according to the present invention will be described with reference to the drawings.
[0011]
[First Embodiment]
1 is a side view of the entire business video camera according to this example, FIG. 2 is a plan view of a shoulder pad, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 5 and 6 are perspective views of the main members separated from each other.
[0012]
In FIG. 1, a shoulder pad 2 according to this example is provided on the bottom surface of a video camera main body 1. The shoulder pad 2 includes an outer skin 3, a cushion 4 accommodated in the outer skin 3, and an aggregate 5 that fixes the shoulder pad 2 to the video camera main body 1.
[0013]
Hereinafter, the detail of each structural member mentioned above is demonstrated.
The outer skin 3 constitutes the outer skin of the shoulder pad 2 and is molded from, for example, soft vinyl chloride, a rubber material, a plastic material, or the like which is not slippery and has flexibility and durability. The skin 3 is molded by rotational molding or other blow molding, and is held in a bag shape on the outer shape of the shoulder pad 2.
[0014]
A rectangular opening 6 is opened on the upper surface of the skin 3 formed in this way (surface on the side in contact with the video camera body 1), and screws are inserted into both side edges of the opening 6. A plurality of small holes 7 are formed. In addition, an elongated hole-like concave portion 8 is formed at a substantially central portion of the bottom portion of the skin 3 (the surface portion that contacts the shoulder of the photographer). The concave portion 8 reaches the opening 6 of the skin 3, and small holes 8 a and 8 a through which screws are inserted are formed in the surface portion.
[0015]
As the cushion 4, foamed soft urethane foam having a slow deformation speed against a sudden load is used. The cushion 4 is housed in the above-described skin 3 so as to conform to the shape. For this reason, the cushion 4 has an opening 9 that avoids the raised concave portion 8 of the skin 3 at the center.
[0016]
On the other hand, the aggregate 5 is made of a plastic material or a metal sheet metal, and includes two lower bone plates 10 and 11 housed in the epidermis 3 and an upper portion assembled to the lower bone plates 10 and 11 from above the epidermis 3. And a bone plate 12.
[0017]
The lower bone plates 10 and 11 are arranged separately on the front and rear portions of the shoulder pad 2, and are inserted along the flat portions 10a and 11a located corresponding to the openings 6 of the epidermis 3 and the back surface of the epidermis 3, It has curved surface portions 10b and 11b that retain the shape of the skin 3. Further, a part of the flat portions 10a and 11a has cutout portions 10c and 11c for escaping the raised concave portion 8 of the skin 3, and a plurality of bolts 13 and 13 are planted on both flat portions 10a and 11a. .
[0018]
The upper bone plate 12 is a flat plate that is assembled to correspond to the flat portions 10a and 11a of the lower bone plates 10 and 11, and holes 12a into which the bolts 13 are inserted are formed at both side edges. Further, a hole 12b that coincides with the small holes 8a and 8a of the concave portion 8 of the skin 3 is formed in the central portion.
[0019]
Next, the assembly procedure of the shoulder pad 2 will be described including FIG. 7 and FIG. First, the cushion 4 is housed in the skin 3 shown in FIG. 7 formed by rotational molding or the like. Since the cushion 4 is made of soft foamed urethane, the opening 9 of the cushion 4 is aligned with the raised concave portion 8 and stored in the outer skin 3 while being compressed and contracted into a small body. Thereafter, the stored cushion 4 is restored to its original shape by its own restoring force and is stored in the outer skin 3 with the same shape. At this time, the cushion 4 is molded from soft foamed urethane, but can be easily stored without being damaged.
[0020]
After the cushion 4 is stored, the two lower bone plates 10 and 11 on the front side and the rear side are respectively inserted between the epidermis 3 and the cushion 4 (see FIG. 8), and the bolts of both bone plates 10 and 11 are inserted. 13 is inserted into the small hole 7 of the epidermis 3. Thereafter, the holes 12a of the upper bone plate 12 are passed through the bolts 13 to overlap the upper bone plate 12 from above the skin 3, and the nuts 14 are tightened and fixed to the bolts 13 (see FIG. 3). Thereby, the edge part of the opening part 6 of the epidermis 3 is pinched | interposed by the lower bone plates 10 and 11 and the upper bone plate 12, and integration of both the bone plates 10 and 11 and the epidermis 3 can be aimed at. Moreover, the shape of the entire shoulder pad 2 is not lost by the attachment of the bone plates 10 and 11.
[0021]
Thus, the shoulder pad 2 assembled as described above is assembled to the recess 1a formed at the bottom of the video camera main body 1, and the small holes 8a and 8a and the upper bone plate 12 are formed from the recess 8 of the epidermis 3. The screws 15 and 15 can be fixed to the video camera main body 1 through the holes 12a and 12a.
[0022]
The shoulder pad according to the present invention configured as described above is a separate member from the cushion 4 and uses the skin 3 which is not slippery and has good flexibility and durability, so that when the video camera is carried by the cameraman on the shoulder, The shoulder pad can be held stably without slipping. In addition, since the cushion 4 is elastically deformed and is well-familiar with the shape of the shoulder, a comfortable fit can be obtained, so that the shoulder is not burdened even during long-time camera photography.
[0023]
For example, 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 has a portion where the cushion 4 is deformed as indicated by the dotted line depending on the position of the shoulder. Since it changes freely like 2a, 2b, it becomes a shoulder pad that is very easy for a photographer to carry.
[0024]
Furthermore, the shoulder pad of the present invention can be removed from the video camera body 1 by removing the screw 15, and the shoulder pad 2 can be removed from the skin 3, the cushion 4, and the upper and lower bone plates 10, 11 by removing the nut 14. Therefore, the shoulder pad 2 can be easily separated when collecting the parts, and as a result, the resources can be reused.
