Description

  The present invention relates to a stand for standing and holding an article.

  When placing a thin rectangular parallelepiped object upright, there is no stability and it will fall over quickly. Further, it is impossible to stand when the bottom surface of the article is curved.

  The TV remote control and mobile phone have a stand, but the seating surface is made wide so that it doesn't fall down, or it becomes a large box shape. If you try to put a thin bag or a soft case for a laptop computer upright, it will be very unstable.

  There are many stands that hold these items in between, but when the items are removed, there is no one that opens the upper part by its own weight.

  Provided is a stand that can place a thin rectangular parallelepiped-shaped article in a stable manner, has a simple mechanism, is compact, and does not take up space.

  An article is placed in the center with a W-shaped stand having a structure in which an L-shaped plate and an inverted L-shaped plate having a rounded corner can be bent at the center.

  When an article is placed in the central part of the W shape, the central part that can be bent becomes the power point, and the lower part (two places) becomes the fulcrum.

  The upper ends of the W-shape serve as action points, and the force is directed inward so that the article is sandwiched.

  By this clamping force, the article is balanced and can be placed stably. The same effect can be obtained even if the bottom surface of the article is curved.

  The clamp-type stand of the present invention is usually W-shaped, and since the upper part is widened, it is easy to put an article therein, and it is sandwiched while balancing at the upper part of the W-shape by the gravity of the article, so It is stable and can be made compact.

  Further, when the article is lifted up a little, it is in an unclamped state, and thereafter, the upper part naturally expands by its own weight and returns to the original W shape.

  Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  A clamp-type stand with a cross-sectional shape as shown in Fig. 1, and a W-shape that can be bent by connecting an L-shaped plate with an R-shaped corner and an inverted L-shaped plate at the center with tape 6 or hinge 11 etc. Place an article 2 that is easy to tip over. The L-shaped plate is a rigid body such as metal or plastic. When the hinge 11 is used, the overall shape is as shown in FIG. The tape 6 or the hinge 11 in the central part only needs to be bent because the L-shape and the inverted L-shape are connected.

  In the case of the tape 6, it is necessary that the L-shape and the inverted L-shape can be bent freely, and if the tape 6 has a spring effect, it cannot be clamped when the light article 2 is inserted. Therefore, the tape 6 is preferably made of a soft material such as vinyl tape.

  Further, as shown in FIG. 13, even if holes are formed in an L-shape and an inverted L-shape and are connected with several places with a thread 12 or the like, it is only necessary that the central portion can be freely bent and connected.

  The center part of the W-shape that can be bent by the gravity of the article 2 is the force point 4, the lower part (two places) is the fulcrum 3, the action point 5 is contracted inward, and the article 2 is sandwiched from the side as shown in FIG.

  This action makes it possible to easily stand the article 2 that is balanced and easily falls.

  When the article 2 is lifted up, the upper part of the clamp-type stand is opened and the shape is naturally returned to the W shape shown in FIG.

  If the bending angle of the L-shape is an obtuse angle (90 degrees or more), even if it is placed as shown in FIG. 7A, it naturally falls down as shown in FIG.

  When the bending angle of the L-shape is an acute angle (90 degrees or less), if the end point (fulcrum 3) of the corner R is on the left side of the L-shaped center of gravity as shown in FIG. Falls by its own weight as shown in FIG. When the end point of R at the corner (fulcrum 3) is on the right side of the L-shaped center of gravity, R does not fall down by its own weight, so R is increased or Claim 2 is adopted.

  When the bending angle of the L-shape is a right angle (90 degrees), the corner R falls if it is larger than the plate thickness, but if there is no R, it cannot fall.

  The smaller the bend angle of the L-shape (the more acute the angle), the larger the corner R must be. Further, if the weight on the right side of the center of gravity is made heavier as shown in FIG. 14 (b), the entire center of gravity is shifted to the right side than in FIG. 14 (a). .

  Regardless of whether the L-shaped bending angle is an acute angle, a right angle, or an obtuse angle, as shown in FIG. 9, as shown in FIG. When it is inserted, it is clamped and balanced, and when the article 2 is taken out, it becomes a clamp type stand characterized by being naturally opened by its own weight and being in an unclamped state. It is characterized in that the upper part is naturally open in an unclamped state.

  When the article 2 is put into the clamp-type stand, the upper part is open so that the article 2 is easy to put in, and the width of the article 2 has a certain degree of tolerance and can be prevented from falling.

  Further, as shown in FIG. 4, it is possible to bend by making the center of the W-shape made of plastic thin. In this case, the upper part is not opened in a W shape, but the center can be easily bent so that clamping and unclamping can be easily performed. It must be able to bend as if a hinge 11 is attached at the center. This is because if the shape (W-shape) having an open top is held at this central portion (spring effect), it cannot be clamped when a light article 2 is inserted. Also, as shown in FIG. 14B, if the weight outside the center of gravity is increased, it becomes easier to open naturally.

  Also, as can be seen from FIG. 9, the opening angle is determined by the gap when the L-shape and the inverted L-shape are joined, and at the time of opening, this clearance becomes 0 and becomes a stopper, which holds the W-shape. it can.

  Depending on the L-shaped bend angle (acute angle) and its length, the upper portion may be difficult to spread. At this time, if the L-shaped bottom is curved as shown in FIG. 10 (a), the fulcrum 3 moves to the position of FIG. 10 (b) due to its own weight, and the center of gravity also moves to the right. ) Is easy to fall down.

  As shown in FIG. 11, a clamp-type stand that opens more naturally can be obtained by connecting the inverted L-shape with the tape 6 or the hinge 11 and making the cross-sectional shape W-shaped. When the bottom of the L shape is curved, the R shape of the corner of the L shape may not be necessary.

  When the article 2 is put into the clamp-type stand, the upper part is open so that the article 2 is easy to put in, and the width of the article 2 has a certain degree of tolerance and can be prevented from falling.

  As can be seen from FIG. 9 and FIG. 11, the clamp-type stand of the present invention clamps the article 2 by sandwiching the article 2, so when the article 2 is placed, the upper part is slightly opened from the phantom line. Clamp.

  Without this clamping allowance, the article 2 is inclined and falls down, but this clamping allowance can give a certain degree of tolerance to the width of the article 2.

  9 and 11, the fulcrum 3 is slightly closer to the center when clamped than when it is unclamped, but there are two symmetrical centers so that a sufficient balance can be achieved.

  If R at the corner of the L-shape is too large, the upper part will open easily during unclamping, and it will be easier to return to the original W-shape, but at the time of clamping, the fulcrum 3 will be closer to the center, making it difficult to balance. .

  This is not due to the shape of the article 2, but due to the shape of the clamp-type stand itself. That is, it is determined by the L-shaped plate thickness, length, and bending angle of the L-shape, satisfies the conditions of FIG. 8 or FIG. 10, minimizes the R-shaped corner R, and maximizes the curvature of the L-shaped bottom. R (ultimately, the straight line of claim 1) is desirable.

  When the clamp-type stand of the present invention is installed on the bottom between the outer cover 7 and the lining 8 of the bag 9 or the soft case, as shown in FIG. Because it can be clamped and balanced by its gravity, the bag 9 and soft case can be prevented from falling.

  Depending on the shape of the bag 9 or the soft case, the clamp-type stand of the present invention is installed in the bag 9 or the soft case, even if the article 2 to be put in the shape cannot be raised by itself. Both can stand up.

  FIG. 6 shows an example in which the clamp-type stand of the present invention is installed at both ends (two places) on the bottom of the bag 9 or the soft case.

  Similarly to the first embodiment, when the article 2 is taken out, the upper part of the clamp-type stand opens and returns to the original W shape.

  In Example 3, the clamp-type stand of the present invention is installed between the outer material 7 and the lining 8, but the inner side of the lining 8 may be used.

  In addition, although a rectangular parallelepiped object has been targeted so far, a cylindrical article 2 such as a tire can be held upright and held by the stand 1 as shown in FIG.

  Generally, when a thin rectangular parallelepiped article is placed upright, a stand is necessary because it is easy to fall down, and is usually a box-shaped seat with a wide seating surface.

  Since the clamp-type stand of the present invention has a simple mechanism and is compact, it has a high utility value in all fields.
