JP5975275B2 - A stepladder for a photographic camera loaded on a cane - Google Patents

Description

  The present invention combines a cane and a stepladder for a photographic machine.

  The feature of the cane is that the weight shifts when a human is walking, but if the cane is used, the weight shift is supported by the support of the cane and the walking can be performed more safely. On the other hand, a stepladder for a photographic machine is desired to be used in order to prevent camera shake at the time of shooting, but the current situation is that it is very troublesome to carry around. Here, there exists the following patent document 1 as what made the cane and the tripod compatible.

JP 2003-52428 A

However, although patent document 1 is a method of accommodating three legs in a cane, there are the following problems.
(1) The thickness of the portion of the cane that houses the legs is not particularly specified, but if it is thick, it is unsuitable for use as a cane.
(2) Although the material of the leg portion is steel wire, the steel wire is too hard to handle if it is 0.8 mm. If you turn it, it stays bent. Stainless steel is harder and cannot be bent by hand. If it is about 0.3 mm, it can be folded with both hands, but if it is bent it will not be restored. Even thin steel pipes cannot be bent and stretched. The H-shape is an umbrella bone, but as is well known, it is curved but is vulnerable to lateral forces. When used as a stepladder, it must be able to withstand the weight and lateral movement from above. Since the weight of the cane body and the weight of the camera are added by the weight of the action of a human hand, stability and fixing are the most important when a camera is set. If you use it on a cane and immediately set a camera and take a picture, you need simplicity. However, none of this necessary requirement is met. Therefore, it seems that such technical ideas are not realistic.

  Therefore, in addition to the above-mentioned features of the cane, the inventor of the present application can carry a staggered camera stepladder, a cane that is lightweight, and a camera stepladder that is light and not bulky. Recognizing this as an important issue, the present invention has been completed.

The first invention of the present invention is a cane and a pillar part constituting the cane, and is provided with three tripod legs provided along the longitudinal direction of the pillar part, and slid in the longitudinal direction of the pillar part. A conical or pyramidal guide for opening the tripod foot, a fixing member for bundling and holding the upper end of the tripod foot, and a tripod foot closed and opened on the upper side of the fixing member It is a stepladder for a photographic machine that is loaded on a cane, characterized in that it is provided with a deformed cap nut that sometimes regulates the movement of a foot for a tripod.
According to a second aspect of the present invention, when the tripod foot is closed, the deformed cap nut is screwed with the pillar portion of the cane so that the tripod foot is sandwiched between the tripod foot and the leg of the tripod. It is a stepladder for a photographic machine that is loaded into the cane, which is sometimes screwed with a guide.
According to a third aspect of the present invention, there is provided a stepladder for a photographic machine loaded on the cane, characterized in that a groove is formed in the guide for guiding a tripod foot portion along the guide.
According to a fourth aspect of the present invention, there is provided a stepladder for a photographic machine, which is charged in the same cane, characterized in that a chain or a string-like member for restricting the open / close state is communicated with a foot for a tripod.
According to a fifth aspect of the present invention, there is provided a stepladder for a photographic machine, wherein the upper end and the lower end of the tripod foot and the fixing member are provided with magnets in contact with the tripod foot. .

The prototype was made of aluminum and magnet (synthetic resin, FRP, UV, iron, carbon, bamboo, wood). It is very light and durable, and can achieve its purpose without causing any problems with carrying. By attaching a small magnet to the required place, the tripod is fixed without coming off the cane. If it is time to shoot, shift the tripod, and set it on a fixed part to stabilize the tripod. Remove the vault hidden behind the cane grip and secure it to the camera. Change from horizontal to tilted neck can be adjusted with a knob-type male screw.
It seems to be useful for preventing camera shake from close-up shooting to telephoto shooting by attaching a camera for shooting while using the product of the present invention as a walking stick for walking, etc. when going on a trip.
Each member and dimensions are not limited because they can be selected at any time depending on the size of the human being used and the height of the person's height, but they were set according to the average height of Japanese people (see Fig. 1). The features of this product are limited to the present invention.

According to the said invention, it has the following effects.
The functions of recent small and light digital cameras have been improved to incorporate the performance of large models. In particular, when taking a picture using a telephoto lens device, camera shake tends to occur, and it is difficult to take pictures well. This invention of the present application quickly changes from a cane to a stepladder, so you can set it up and take a photo. Therefore, it is possible to set a large size model. The invention is designed to be lightweight and compact.

FIG. 3 is a detailed view of the grip portion of the cane.
1 is the grip part of the cane, the grip of figure a is horizontal. Reference numeral 3 denotes a dial for raising and lowering a camera mounting screw, with reference to a detailed view of the handle. In other words, it is a fixing screw for a camera in which 2 comes out when 3 is twisted. On the other hand, when 2 is twisted, 2 fits in the handle and does not get in the way when it is used as a cane. 4 is a male screw that can finely adjust the direction of the camera. 5 is a cap nut which fixes the grip part of 1 to the pillar of 6.
7 is a hole for connecting the handle and the pole of the cane. 8 is a washer for smoothly rotating the vault 2. 9 is a part connecting the handle and the column of the cane, and is for making an arbitrary tilt angle from the horizontal, but the shape is an arc. Since the surface is rough so that friction occurs, tightening 4 will fix it at an arbitrary angle.
FIG. b is an explanatory diagram in which the grip is moved up and down.

(Fig. 4)
FIG. 4 is an explanatory diagram of the pillar portion of the cane. 2-1 The upper 20 pie of the pillar, 3-1 can be used by adjusting the height of the pillar and looking at the camera during shooting, 3-2 is a screw for fixing the 5-1 cap nut, 4-1 is 2- Adjustment hole 4-2 when 1 is extended and used, 5-2 is fixed to prevent lifting of the cap nut screw tripod attached to 4-4. 4-3 is an iron material. When the tripod is in the cane state, it will be in the way if it is left open, so fix it to 4-4. In that case, the strong magnets 6-1 (see FIG. 5) are attached to the bottom of the tripod 4-3 and fixed by magnetic force. In addition, when set on a tripod, the upper part of the tripod has a magnet 6-1 (see FIG. 5), so it cannot be removed by magnetic force. 5-3 is a tripod fixed and stable component, that is, a guide. Since the 5 mm groove is dug, the tripod stick can easily fit into the triangular groove and be secured. 5-4 is a lower part of the cane, and the height of the cane can be finely adjusted by taking out the expansion / contraction pipe contained inside by adjusting the part 5-6. 5-5 is a sticking rubber cover for the cane.

(Fig. 5)
FIG. 5 is a detailed explanatory view of a tripod. The thickness of the feet was 12 mm pie, but this is not the limit. 6-1 magnets, 6-2 legs, and the same length are three. 6-3 Built-in telescopic legs that can be extended for the set leg length, and extending the legs can increase the overall height of the stepladder, making it possible to handle places with poor scaffolding. . The 6-a chain is passed through the 6-4 hole and fixed when the leg is opened. Pass 6-b through 6-5 hole and let the fixed chain that the leg does not open too much pass. No. 2-5 has a tripod fixed stable part triangular pyramid with a groove having a depth of 5 mm in a triangular position on a plane, and a tripod is set along the groove.

(Fig. 6)
FIG. 6 is a detailed view of 2-5. A groove is dug in the conical member so as to be triangular from the plane. This is a guide in which the three tripod members are correctly triangular. When the tripod is pressed with 5-2 in FIG. 4 and tightened with the cap nut of 5-1, the tripod is fixed by this guide, so the entire stepladder is stabilized. . Note that FIG. 6a is a detailed view because two plate-like members can be considered without using conical parts.

(Fig. 7)
FIG. 7 is a detailed view of 5-1 to 5-7. Reference numeral 5-1 denotes a modified cap nut. When the role of the upper groove is a cane, it is fixed to the pillar 2 in FIG. When setting a tripod, push down the leg and fix the tripod with 5-2. The lower part of the cap nut is added to the male screw 2-6 in FIG. 6 and fixed with a screw, whereby 5-2 is fixed against the pressure from the bottom of the tripod, and the stepladder is kept stable. A strong magnet is attached up and down by attaching an iron plate to the inner base of 5-2. When a cane is attached with a 5-3 magnet, even if the three tripods are pushed upward, they are attached to the magnet of 5-2 by magnetic force, so they cannot be easily removed even if they are used as a cane.

  The products according to the present invention have considered the necessity of stepladders for camera shake prevention measures such as telephoto in the increasingly developing camera industry and photography that requires stepladders. However, how convenient it is to shoot without the idea that the stepladder is bulky, and the current aging of the human society, the camera is becoming a very popular hobby for the elderly, especially for travel. The wand has a stepladder role to help the inexperienced photographers and elderly people as much as possible.
