[0001] TRIPOD CLAMPING DEVICES FOR OPTICAL INSTRUMENTS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tripod clamping apparatus for an optical apparatus which can be used by being fastened to a tripod, more particularly, to a clamping apparatus for clamping a ball head fixed on a tripod, to be.

Figure 1 below is a quick shoe named JP05150352A published on June,

Figure 1

In the configuration of the present invention, the shoe plate 3, which is detachable with respect to the shoe main body 2, is formed with an engagement portion 3a having a circular tapered circumferential surface in the lower half of the shoe plate 3. On the other hand, in the shoe body 2, the engagement portion 3a of the shoe plate 3 is formed with an arc-shaped receiving portion 2b engaged with one side portion of the shoe body 3 so that the other side portion of the engagement portion 3a The locking lever 8 for locking the locking lever 8 is mounted.

Claim 1

Wherein a substantially arc-shaped receiving portion to which a lower engaging portion of the shoe plate is engaged is formed at a periphery of one side of a shoe plate on which at least a lower engaging portion is formed in a substantially circular shape and a mounting surface portion on which the shoe plate is mounted, And a shoe main body equipped with a locking lever for locking the lower engaging portion of the shoe plate against the support portion is completed.

As can be seen from the above document, in the clamping device used by being fastened to the tripod, at least the shoe plate having the lower engaging portion formed in a substantially circular shape and the side surface portion of the side surface of the mounting surface portion on which the shoe plate is mounted, Wherein a shoe main body having a substantially arc-shaped receiving portion engaging with an engaging lever for engaging the lower engaging portion of the shoe plate is provided on the other side of the mounting surface portion so as to be opposed to the receiving portion, It is a reality that it is manufactured and used only for the purpose of using the device purely when the image is stored.

The present invention is based on the development of science, and high-quality optical apparatuses developed at times are developed, and consumers' desire to use them is desired to include high-quality images quickly, accurately, and conveniently. However, When the plate is attached to the clamp, the clamping device is carried out only in one direction, either forward or backward, or leftward or rightward,

JP05150352A Jun. 18, 1993 Description of the invention The quick shoe is capable of attaching the plate to the clamp at either the front, the back, or the left or the right. However, when seen from the drawing, the fastening means can be used by fastening the plate to the right- Can be mounted and detached more quickly than other products. However, this invention is also designed to use an optical device only when the plate is fastened securely to the clamp while staying in a place for a long time, so that when a moving object or a place is moved occasionally, There are many inconveniences, so I avoided the use of a tripod and taken with my hand, I can not get the desired images or photos.

In order to overcome the above problems,

As well as existing products, not only can you stay in one place for a long time, fasten the plate to the clamp,

The plate is fast and easy to insert into the clamp and fastened to the inside of the clamp by the force of pulling the plate by hand while the plate is inserted without fastening with the fastener, In order to be able to take the plate out of the clamp,

A fastener constituting part 305a constituting a fastener capable of pressing the bottom part 1111 by driving the fastener when the plate is inserted into the clamp and fastened with the fastener is inserted into the fastening part entrance direction Is inclined in the direction of the plate contact portion (301)

The fastener constituting portion 305a constitutes a fastener 305b having a male thread portion 305b-1 by constituting a female thread portion mutually compatible with the male thread portion of the fastener.

Since the fastener 305b is formed on the lower surface,

In addition to being able to stay in one place for a long time, it is possible to take a picture by fastening a plate fastened to an optical device to a clamp,

When taking an emergency shooting or moving object on the move, the plate can be quickly inserted into the clamp without any direction in front, back, left, right, and fast,

Due to the structure in which the end portion of the fastener is inserted into the bottom groove 1111b even when the fastener is inadvertently inserted by mistake owing to the safe structure in which the clamp covers the plate at the time of photographing while moving the optical device by moving the short- The optics have been removed from the clamp to reduce the chance of damage to the optics,

The plate can be inserted into or removed from the clamp quickly, which makes it possible to reduce the inconvenience of moving the optical device to the tripod

The front portion of the opening has a safety surface (308a) formed by flattening the fingers so that the fingers do not hurt, and the corner portion is formed by rounding.

As shown in FIG. 5, the seating surface protecting portion 303-1 is formed on the surface of the seating surface to protect the seating surface and insert the plate into the clamp so that the plate can work better in the clamp when the optical device is handled A groove 303-1a, which is flat and has a shape similar to the surface of the seating surface, into which the end of the fastener and the tripod fastener can be inserted, and a safety pin A safety pin groove 303-1b into which a head portion of the safety pin groove can be inserted, and a pressure-sensitive adhesive having adhesive property is formed on the lower surface.

The following is illustrated in the figure.

Figure 4

 In FIG. 4, numerals in the inside of the rectangular part indicate numbers on the inner side, and the upper side inner side 1 (301) is a plate contact part. When the inserted plate is pulled or fastened with a fastener, the clamp contact part 1113 And the lower inner lateral side 2 is a portion constituted for inserting the hand-restraining portion 1112 and the bottom portion 1111 formed at the lower end of the hand-restraining portion And has a semi-cylindrical shape.

Next, the fastening method of the present invention will be described.

The plate 1000 having the optical device contact portion 1300 shown in Fig. 5 and the handle portion 1100 formed at the lower end of the optical device contacting portion is inserted into the clamp 300 in the front, back, left, When the fastener pushes the bottom part 1111 of the plate as shown in "part D " in Fig. 8,

As shown in "E part" of FIG. 8, the inside seating surface 303 of the hand-restraining portion groove in which the hand-restraining portion is inserted supports the end portion of the inner bottom surface 1111a of the inserted plate,

The bottom surface 1111a of the entrance surface in which the plate is inserted is at an angle to the seating surface 303 while the bottom portion is in contact with and presses the fastener,

 As shown in the "F part", the inner clamp contact part 1113 has a method of making the plate 1000 to be clamped to the clamp 300 while being in contact with the upper part while making an angle with the plate contact part 301 .

The present invention relates to a clamping apparatus and a method of clamping the same. [0001] The present invention relates to a clamping apparatus for clamping a workpiece, The contact portion of the lower portion of the contact portion 1300 is a contact portion of the optical device 1304 is convex portion 1 1305 is an optical device contact pad 1150 is a fastening portion 1170 is a bottom plate 1190 is a sliding plate 300 is a clamp 301 is a plate contact portion 302 is a plate- Hand-restraining groove 302a: clearance 303: seat surface 303- [0001] The present invention relates to an insertion surface protecting part, and more particularly, to an insertion surface protecting part, an insertion preventing part, an insertion preventing part, a fastening part, a fastening part, a fastening part,
