JP4904087B2 - Hinge structure of flip-up counter - Google Patents

Description

  In this application, in various counters such as cashier counters used at convenience stores (hereinafter referred to as convenience stores), the counter top plate is jumped up and used as an entrance so that it becomes a passage for people to enter and exit these counters. The present invention relates to a hinge structure of a flip-up counter.

  In the convenience store, various counters such as a cashier counter are used (see Patent Document 1). Some of these counters have a flip-up counter so that people can enter and exit the counter. This flip-up counter is provided as a part of a long counter, and one side of the counter top plate is rotatably connected to an adjacent counter (hereinafter, fixed counter) via a hinge. You can jump in and out of the top board. In addition, the lower side of the top plate is a swing door, and these swing doors and the top plate that can be flipped up can enter and exit.

In such a flip-up counter, a so-called piano hinge is generally used for the hinge of the top plate. The piano hinge 100 has a shape as shown in FIG. 19 and is typically used for an opening / closing part of a lid of a piano keyboard. When used for a piano lid, the hinge has the same length as the left and right width of the lid. As a conventional flip-up counter, a piano hinge having a length corresponding to the front and rear width of the top plate 110 is used. Further, in this case, the top plate is rotated 180 °, and as shown in FIG.
Japanese Patent Laid-Open No. 2005-211125

  However, in the counter using the piano hinge 100, the shaft 101 of the piano hinge 100 protrudes from the top surface of the top plate 110 even when the top plate 110 is closed, and the product is placed on the top plate 110. Sometimes it is a problem, such as getting caught.

  Further, since the piano hinge 100 is a hinge having the same length as the front and rear width of the top plate 110, the gap between the top plate 110 and the 120 fixed counter is closed with the piano hinge 100. There is no worry that small items will fall off. However, when using a device other than the piano hinge 100 and interspersed in two or three places in the front-rear width direction of the top plate 110, there is a gap between the top plate 110 and the fixed counter 120. This is a problem because small items fall from this gap.

   Such a flip-up type counter rotates the top plate 110 by 180 ° when it is flipped up and opened. However, the top plate 110 to be rotated is about to fall freely by its own weight. The opened top is carefully removed by hand so that it will not drop and cause impact or noise. In other words, when opening, it is opened by placing the top plate rotated 180 ° on the fixed counter, and when tightening, it is returned 180 ° and held by hand to the end and closed so as not to drop. .

  Accordingly, the present invention has been made to solve the above-described problems, and the hinge does not protrude from the top surface of the top plate, and there is no gap between the top plate and the fixed counter. It is an object of the present invention to provide a hinge structure for a flip-up top plate that does not drop by its own weight and cause impact or noise.

In order to solve the above problems, the invention of the hinge structure of the flip-up counter according to claim 1 is a hinge structure of the flip-up counter in which one side of the top plate is connected to the fixed counter via the hinge. It has the following features.
(A) The hinge is provided with an arrangement in which the pivotally attached portions where the arms provided on the pair of hinge plates are pivotally attached to each other so that the pair of hinge plates can be folded.
(B) When the top plate and the fixed counter are fixedly connected to the opposed surfaces of the hinge plate and the top plate is rotatably connected, and the pivoting portion is folded, The posture is located above the hinge and is arranged so as not to protrude from the top surface of the top plate.
(C) A skirt plate extending substantially flush with the top surface of the top plate from the one side of the top plate is provided to extend in a substantially cylindrical shape centered on the pivot axis, and further on the skirt plate Is formed by cutting a groove for entering the arm at the position where the arm on the fixed counter side hits the skirt plate when the top plate is rotated in the flip-up direction.

  In the invention according to claim 2, in the invention according to claim 1, when the entry groove is flipped up, the arm on the fixed counter side enters and comes into contact with the bottom of the groove, so that the top plate is positioned at a predetermined angular position. It is characterized by being formed at a groove depth that stops at.

  The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, the hinge is a torque hinge having a predetermined rotation resistance.

  The invention according to claim 4 is characterized in that, in the hinge structure according to any one of claims 1 to 3, the top plate is connected to a fixable place other than the fixed counter instead of the fixed counter. The “fixable part” may be, for example, a wall, furniture, furniture, or the like. For example, when there is a wall or furniture at the end of a long counter, a flip-up top plate is attached to the side of the wall or furniture.

According to the present invention as described above, in claim 1, since the hinge does not protrude from the upper surface of the top plate, there is no problem such as the hinge being caught when a product or the like is handled on the top plate.
Also, since the piano hinge is provided over the entire length of one side of the top plate (that is, the front-rear width of the top plate), the gap between the top plate and the fixed counter is closed with this piano hinge. In this regard, in this application, even when the hinges are not long like a piano hinge and are provided so as to be scattered on one side of the top plate, the gap between the top plate and the fixed counter is covered with the skirt plate. Therefore, there is no problem that small items fall out of the gap.
Even if such a skirt plate is provided, when the top plate is rotated, this skirt plate rotates together with the top plate in an arc shape so that it does not interfere with the other party's fixed counter. It has become.

  In claim 2, the rotation range of the rotated top plate can be limited. For example, the rotation can be stopped at an angle of about 95 ° to 100 ° instead of the conventional 180 °. The depth of the groove can be formed on the top plate and the top plate can be stopped in a standing state.

  According to the third aspect of the present invention, since the hinge is a torque hinge, it is possible to regulate the free fall of the top board by its own weight.

  In Claim 4, the attachment location of a top plate can be expanded other than a fixed counter.

  Next, the embodiment of the flip-up counter hinge structure of the present invention will be described with reference to the drawings.

  1 to 3 show a counter 1 used in a convenience store, and a top plate 10 on the side to be flipped up (hereinafter referred to as a rotating top plate 10) is a top plate 20 of a corner counter 2 as a fixed counter (hereinafter referred to as a counter top). A flip-up counter 3 connected via a hinge 30 is provided on the fixed top plate 20). As shown in FIG. 4, the hinge 30 attached to the rotating top plate 10 is attached via an attachment base 40 of the hinge 30 fixed to the base end surface 11 of the rotating top plate 10. Further, the distal end side 12 of the rotating top plate 10 is received by a receiving portion 50 provided on the side surface of the counter block 4 installed separately, and is usually flush with the fixed top plate 20. A swing door 5 is provided below the rotary top plate 10 so that it can be moved in and out when the rotary top plate 10 is flipped up and opened.

  As shown in FIG. 5, the hinge 30 is configured such that the arms 32 provided on one side of the pair of hinge plates 31 are pivotally attached to form a pivotal attachment portion 33, and as shown in FIG. The plate 31 is provided so that it can be folded.

  The hinge 30 is a torque hinge having a rotational resistance. That is, in the pivot attachment portion 33, a pair of arms 32 superposed for pivot attachment and a spring-like washer (not shown) are pivotally attached, and the pair of arms 32 over which this washer is superposed. It has a turning resistance by pressing. In this embodiment, a hinge is used which has a rotational resistance that stops even if the rotary top plate 10 is released at an angular position in the middle of opening and closing, and stops at that angle, and does not come down due to the weight of the rotary top plate 10. ing.

  As shown in FIGS. 7 to 9, the mounting base 40 of the hinge 30 is formed in a long and thin metal box shape having the same length as the front and rear width of the rotary top plate 10, and a skirt portion 41 having an open bottom, and the skirt portion 41. And an L-shaped plate portion 42 for attaching to the rotating top plate 10. The L-shaped plate portion 42 has an L-shaped vertical plate portion 44 joined to the back surface 43 of the skirt portion 41, and the L-shaped corner portion 45 is directed to the lower corner of the rotary top plate 10 as shown in FIG. It is supposed to be fixed.

  Here, as shown in FIG. 11, the skirt portion has a skirt plate 41a extending substantially from the rotating top plate 10 to the top surface of the top plate, and the skirt plate 41a is shown in FIG. In this manner, the hinge 30 mounted in the skirt portion 41 is extended so as to have a substantially cylindrical shape centered on a pivot shaft 34 (the pivot shaft 34) (see reference numeral 41a '), and a rotating top plate 10 and the fixed top plate 20 have a width that can cover the gap. As shown in FIGS. 10 and 13, the hinge 30 is arranged so as to be inserted from the lower opening 41 b of the skirt portion 41, and one hinge plate 31 a is fixed to the vertical plate portion 44 of the L-shaped plate portion 42. The hinge plate 31b is fixed to the fixed top plate 20. As a result, the substantially cylindrical skirt plate 41 a covers the hinge 30.

  Further, the skirt portion 41 and the skirt plate 41a provided in this way rotate together with the rotating top plate 10 when the rotating top plate 10 is flipped up and rotated. Specifically, the hinge 30 rotates around the pivot shaft 34. When rotating in this way, the extended portion 41 a ′ of the skirt plate 41 a is formed in a cylindrical shape centered on the pivot shaft 34, so that it can rotate without hitting the fixed top plate 20 that is in close proximity. However, at this time, the lower side 46 of the skirt plate 41a corresponding to the attachment location of the hinge 30 comes into contact with the arm 32b on the fixed top plate 20 side. For this reason, the skirt plate 41a at the contact position is formed with a groove 47 for entering the arm 32b so that the arm 32b can be rotated while entering the groove 47 as shown in FIG. It has become. A portion 48 of the skirt plate 41a sandwiched between the pair of entrance grooves 47 is bent inward, but this portion 48 hits the hinge plate when flipped up, so that it is formed as a relief to avoid this. It has been made.

  The entrance groove 47 jumps up the rotating top plate 10 and comes to an angle position rotated about 95 ° from the closed position as shown in FIG. However, as shown in FIG. 16, it is formed to have a groove depth that comes into contact with the groove bottom portion 47a of the entering groove 47, and the rotation of the rotary top plate 10 is stopped by using this groove bottom portion 47a as a stopper. It is like.

  The usage method of the hinge structure of the present embodiment having the above configuration is as follows.

  The rotating top 10 is normally in a closed state as shown in FIG. 1, and the tip 12 of the rotating top 10 is placed on a cushion 51 provided on the upper surface of the receiving portion 50. It has become.

  When the rotating top plate 10 in the closed state is lifted by hand, as shown in FIGS. 15 and 17, it opens to about 95 ° slightly exceeding a right angle and stops. That is, there is no need to rotate 180 ° as in the prior art, and only the opening operation necessary to enter and exit the counter 1 is sufficient.

  Further, after the entrance / exit to the counter 1 is finished, it is closed by hand, but even when the rotary top plate 10 is released at an angular position as shown in FIG. 18, it stops by the rotational resistance of the torque hinge. It is designed so that it will not fall freely. Therefore, the rotating top plate 10 in the opened state can be lowered by hand, and can be changed by holding it at a position approaching the closed position and closing it so as to hold it down.

  The rotating top plate 10 that is closed and in a normal use state is flush with the fixed top plate 20, but the skirt portion 41 is provided in the gap at the boundary so as to fill the gap. There is no such thing as falling from the gap. Further, the skirt portion 41 has a skirt plate 41a on the upper surface that is flush with both the rotary top plate 10 and the fixed top plate 20, and is one of the hinges like a counter using a conventional piano hinge. There is no problem such as the part sticking out from the top board and the luggage is caught.

  The present invention is not limited to the above-described embodiments, and may be implemented in any manner without departing from the spirit of the invention.

  The mounting partner of the top plate (the rotating top plate 10) is not limited to the fixed counter (fixed top plate 20), but may be a wall, furniture, furniture, or the like. When the end of the counter placed in the longitudinal direction is in contact with the walls, furniture, or furniture in the room, and the counter at the end is a flip-up counter, the hinge is provided on the counter side. However, it may be provided on the wall or furniture side.

  In addition, the torque hinge does not stop at that position even if the hand is lifted at an arbitrary flip-up position as in the embodiment, but a torque hinge that opens and closes slowly from that position. It may be used. Thereby, even if let go, it can be closed quietly by its own weight, and impact and noise can be suppressed. Alternatively, it is possible to use a torque hinge that does not have a turning resistance when opened and generates a turning resistance only when it is closed.
