JP2006170424A - Tripod opening method for functionally opening legs of tripod type stand with simple operation of leg opening bar connecting main leg body to two sub leg bodies and simply opened type tripod using the same - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide smaller and lightweight tripod capable of being opened/closed with simple operation and being quickly moved and stored. <P>SOLUTION: In general, tripod or a tripod type stand has leg portions in a semi-fixed form to be opened/closed only by applying certain force thereto. To open/close the legs with simple operation, operation and relative attachments are required for giving certain force thereto, eventually increasing the weight and outer shape and impairing portability and storage performance. So, considering a mounting method for linking the leg bodies to a base, the leg bodies are turnably journaled to the base and a stay mechanism with a leg opening bar is provided on one of the leg bodies for opening/closing the tripod, thus allowing the legs to be opened with a one-touch operation. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention is used for a tripod stand used for photography, various surveys, etc., a tripod easel used for sketching a painting, or for displaying various guides and menus in an office presentation or store. The present invention relates to a tripod stand opening method adapted to a general stand and a tripod for a guide plate, and a one-touch opening tripod using the same method.

  For work such as photography and terrain surveying, a tripod stand that is portable and movable is used, and it is usually common to stack each work while repeatedly moving and re-installing each work. It is. In addition, painting sketch easels and store signboards are often installed at the beginning of the work, and are often left for a certain period of time. In either case, installation and storage can be done with one touch, and they are compact and portable. What was easy to do was demanded.

  However, at present, the opening and closing of the legs relies on manual work each time, and it is very inconvenient for work with a lot of movement. Especially when taking a lot of work, such as taking a picture, it is often necessary to open and move the leg with a scissors on which the camera is mounted. It is extremely effective without impairing efficiency.

  For example, Patent Document 1 proposes a tripod opening / closing mechanism of a conventional technology that can be opened / closed with a single touch and the operability has been dramatically improved. However, in this method, the three legs constituting the tripod are operated separately without cooperation. Therefore, although the operability has been improved as a leg opening operation, it is not necessarily an effective one-touch leg opening means because the three legs cannot be opened at the same time. .

JP-A-8-121687

  Even without troublesome operations in this application, you can open the tripod's tripod at the same time with a single touch, and then just lift the tripod's body to automatically close the tripod when it leaves the ground. Incorporate a mechanism that can be easily operated by anyone when changing or moving frequently. A one-touch tripod opening method, and a mechanism for opening the leg, characterized by constructing a cooperative operation between the legs and arranging a movement knob linked to the opening bar so as to function easily. The challenge was to propose a one-touch tripod-type tripod that uses the camera.

  In this application, we considered two things and decided to solve the problem based on this. In other words, the first is to allow the legs of the three legs to be opened at the same time with a simple one-touch operation at one location. The second is to make the structure so that it can be converged instantly and safely when the legs are closed.

  The tripod of the present invention comprises a stay provided on the main leg of the tripod and two open leg bars connected to each auxiliary leg from the slit of the stay. Basically, the leg bar slides by simply operating the moving knob and pushes each leg to widen the gap between the main leg and the sub-leg to open the leg.

  The point of this kind of one-touch tripod opening method is to construct a simple operation mechanism and design it so that anyone can easily operate it. That is, as in Patent Document 1, each leg is individually operated and is not installed by stacking each operation, but is configured to be completed by one operation. Furthermore, here, the device for opening the leg is easily installed in the vicinity of the base, which is the mounting portion of each leg of the tripod, and is devised so that it can be applied to a conventional general tripod stand. .

  In addition, since each leg of the tripod linked to the base is freely opened and closed, when the grounding part of the leg moves away from the ground, each leg returns vertically with its tip portion directly below due to its own weight. The three legs are automatically closed and gathered in the center, making it easy to bind and storing and moving. In addition, since the operation unit can be reduced in size and weight, it is suitable for carrying an easel for painting.

  Therefore, the shape of the stay, the slit and the leg bar should be considered in accordance with the shape of each leg, but depending on whether each leg is cylindrical or prismatic, the slit of the stay It is desirable to consider so that the angle of the connecting pin that fits in and the attachment angle of the leg bar can be made to coincide with each other.

  In the present invention, it is configured so that both the opening leg and the closing leg can be completed with the minimum necessary operation as described above. Therefore, anyone can easily and quickly perform one-touch operation anytime, anywhere. It was assumed that it could be executed reliably by the operation of.

  If the tripod opening method of the present invention or the tripod is used, the tripod stand can be easily and flexibly installed with a single touch. Extremely high work efficiency can be obtained when installation is frequently performed.

  In addition, the present invention can reduce the size of the tripod stand and reduce the attachment parts for the legs and accessories for adjusting the angle, so that it is extremely effective for moving to a remote place where portability is important. . Moreover, the utility of downsizing can create a spare space for movement and storage space in a store or office, and promote effective use of a storage place or the like.

  The current tripod or tripod stand can be broadly divided into those with lightweight metal legs such as aluminum and those with natural materials such as wood. The body can be expanded and contracted, and many legs can be individually adjusted. In the implementation of the tripod opening method of the tripod according to the present invention, since it can be generally provided in the vicinity of the base, it is applicable to both regardless of the difference in the material of the leg and the presence or absence of elasticity as described above. Is something that can be done.

  In addition, the tripod using the same method as the one-touch type leg opening method of the present invention can be installed by opening the tripod with one touch just by sliding the movement knob. Because it closes at the moment when it leaves the ground surface, anyone can carry it easily and use it wherever it is.

FIG. 4 is a plan view showing the linkage between the stays representing the main functional parts of the present invention and the open leg bar, and FIG. 5 is an enlarged cross-sectional view taken along the chain line AA of FIG. is there.

  1 and 2, a movement knob 13 is located on the upper portion of the stay 7 provided on the main leg 1, and an opening leg bar 9 extends substantially horizontally from the movement knob 13 to the left and right. The tip is pivotally supported on the side surface of each sub-leg 3 by a support shaft b21, and each sub-leg 3 is pushed back by the open leg bar 9, and the main leg is retreated. It can be seen that the space between 1 and each subleg 3 is spread.

  That is, in the main leg 1, when the learning knob 13 fitted in the slit 11 of the stay 7 is slid along the slit 11 and moved to the upper part of the stay 7, Each open leg bar 9 attached to the provided connecting pin 15 functions as a piston and pushes each auxiliary leg 3 to open the leg.

  FIG. 3 shows a form after the legs are closed in FIG. 2, in which the learning knob 13 slides down to the lower part of the stay 7 provided in the main leg 1, and the left and right leg bars 9 are respectively shown. The figure shows that the sub-legs 3 are gathered in the center by closing the space between the legs, changing to a substantially vertical shape.

  FIG. 4 shows the stay 7 as the main functional part of the present invention, and FIG. 5 describes the function and role of the stay 7. In FIG. 4, a plurality of notches are provided in the slit 11 of the stay 7 to form the locking portion 17. In this case, when changing the leg angle of the tripod, the shape and its position may be determined appropriately so that the learning knob 13 can be locked at an appropriate position.

  Here, the upper end portion of each leg bar 9 is pivotally supported on the side surface of each sub-leg 3 by the support shaft b <b> 21, so that the movement knob 13 is moved along the slit 11 of the stay 7. When moved upward, each leg bar 9 corresponds to any angle, and the tripod having each leg can be installed with an appropriate leg width and adapted to the shape of the ground contact surface. Is.

  As described above, the tripod opening method by the stay 7 of the present invention is such that the movement knob 13 shown in FIG. 4 is set to (1), the upper part of the slit 11 is set to (2), and the opening bar 9 is pivoted to the auxiliary leg 3. When the supported part is (3), it can be described by a triangle having vertices (1), (2), and (3). That is, when the legs are closed, the sides (1)-(2) are substantially equal to the sides (1)-(3), and the sides (2)-(3) are smaller. When (1) is slid and moved to the upper part of the slit 11, the sides (1)-(2) become smaller and the sides (2)-(3) become larger, that is, an open leg state is indicated. It becomes.

  FIG. 5 is an enlarged cross-sectional view seen from the direction of the arrow with the chain line AA in FIG. 4 as a cut surface. Here, a learning knob 13 provided with a connecting pin 15 is fitted in the slit 11 of the stay 7, and an open leg bar 9 is pivotally supported on the connecting pin 15 by a support shaft a 19. In this case, it is preferable that the attachment angle of the open leg bar 9 on the connecting pin 15 is adapted to match the connection angle with respect to each auxiliary leg 3 so that the open leg bar 9 moves in parallel.

  In the one-touch open leg tripod according to the present invention, it is necessary that the legs 1 and 3 are connected to the base 5 so as to be freely opened and closed, but connected by a support shaft made of a general material. If it is sufficient to exhibit the characteristics of the present invention, and when the grounded portion of each leg 1 and 3 that is opened is in contact with the floor or the ground, contact friction due to the total weight of the tripod occurs, There is no need to worry about wobbling or tilting the tripod.

  As described above, according to the tripod opening method of the present invention shown in FIG. 1 or FIG. The attached leg bar 9 spreads each auxiliary leg 3 and opens the leg with one touch. Further, when closing the leg, the habit knob 13 fitted to the stay 7 is moved along the slit 11 only by lifting the vicinity of the base of the tripod and pulling the grounding portion of each leg of the tripod away from the ground or the like. As shown in FIG. 3, the three legs 1, 3 of the tripod are gathered vertically under the base so that they can be easily stored. Become. Thus, with the tripod of the present invention, installation and storage can be performed by one-touch operation.
