JP 2003-102600 A

  A gas cylinder is provided with an outer cylinder, an inner cylinder (piston), and an outer cylinder, both of which move relative to each other to expand and contract as a whole, and generally has an outer cylinder as a movable part. Conventionally, as described in Patent Document 1, the lower end of the fixed portion of the gas cylinder is rotatably attached to the case body with a pin, and the upper end of the movable portion is rotatably attached to the upper lid with a pin. Yes.

  Therefore, when the upper lid is opened and closed, the gas cylinder expands and contracts while changing its posture in side view. In other words, the gas cylinder opens and closes the upper lid by extending and contracting while changing the side posture.

  However, in the configuration in which the gas cylinder is directly attached to the case main body and the upper lid in this way, the gas cylinder is disposed in a forward inclined posture in the closed state, and therefore, a rear space for disposing the gas cylinder As a result, there was a risk that the display space would be narrowed (the display case would inevitably become larger if the depth of the display space was increased).

  In order to enhance the function of holding the upper lid in the raised state, it is preferable that the gas cylinder is tilted as far forward as possible in the open state. However, in the prior art, if the opening of the door is increased, the gas cylinder Since it is close to a standing posture, the function of holding the upper lid in an open state is weak.

  This invention makes it a subject to improve such a present condition.

Display case of the present invention, as a basic configuration, a case body having an exhibition space open upward, and a lid for closing the exhibition space from above, the exhibition space is arranged on the rear side of the said case body spreads on the front side of the back partition plate, attached to the one of the rear of the back partition plate is formed the rear space, the upper lid, the case body so as to rotate flipped about its rear end together are the exhibition spaces are transparent plate that is visible is provided with, a further splashed easily if occupying the gas cylinder the rotation of said upper lid.

Before SL gas cylinder provided with a fixed portion and a movable portion, the gas cylinder, the back and and sites below the top cover of the case body, and arranged so as to upwardly extending substantially in a vertical posture cage, and a part of the front of the rotation center of the upper end and the upper lid of the gas cylinder, by the interlocking member disposed on said rear space, connected to a state where expansion and lid rotation of the gas cylinder is allowed is doing.

Furthermore, the interlocking member, while attached to the upper end of the gas cylinder so as to tilt back and forth about its lower end, on the lower surface of the upper cover, the upper end of the interlocking member is fitted so as to be moved back and forth bracket having a long hole which are projected downward, the slot is formed in the back downward in a side view in a concave arcuate top end of the interlocking member in the closed state, located to the rear of the slot In addition, the upper end of the interlocking member is set so as to shift to the near side of the elongated hole as the upper lid opens.

  According to the present invention, since the gas cylinder is disposed in a substantially upright posture at the back of the case body, the depth dimension occupied by the gas cylinder may be small, while the interlocking member also moves up and down while rotating. The depth dimension of the rear space can be reduced, and as a result, the depth of the arrangement space between the gas cylinder and the interlocking member can be made as small as possible, and the depth of the exhibition space can be made as large as possible without increasing the size of the display case. be able to.

  Furthermore, since the upper end of the interlocking member is located in front of the long hole in the bracket when the upper lid is flipped up, the supporting force for stretching the upper lid in the opened state is high. The function of holding the upper lid in an open state has a high advantage.

  Next, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view of a display case. The display case includes a case main body 2 having an exhibition space 1 opened upward, and an upper lid 3 that is flipped up and attached to the rear part of the case main body 2 so as to be rotatable. Yes. A double door 4 is provided on the front surface of the case body 2. Further, the upper portion of the case body 2 is in a state of projecting forward, and the upper lid 3 is tilted forward in a side view in the closed state.

Details are omitted, display cases of this embodiment, it is possible to communicate the exhibition space of each display case by connecting the plurality to the left and right in a series, Therefore, the position on the left and right sides of the exhibition space The upper side plate 5 is detachable from the case body 2.

  Hereinafter, the details will be described with reference to FIG. 2 is a schematic side cross-sectional view showing a part of members by phantom lines, FIG. 3A is a side cross-sectional view showing an opening / closing assist mechanism of the upper lid 3, and FIG. 2B is a view taken along line BB in FIG. Sectional view, (C) is a sectional view taken along the line CC in (A), FIG. 4 is a partially broken view taken along the line IV-IV in FIG. 3 (A), and FIG. Figure).

As can be understood from FIG. 2, the case main body 2 includes a main body frame 6 made of a steel material such as a square steel pipe, and the side plate 7, the back cover 8, and the door 4 are attached to the main body frame 6. An adjuster 8 is attached to the lower surface of the main body frame 6. Furthermore, a caster 11 is attached to a reinforcing member 10 that spans the lower horizontally long member 6 a that forms the main body frame 6 through a bracket 9.

Back of the main body frame 6 is constituted by a back rungs 6b and rear support 6c in a plurality of stages, also, part of the display portion of the main body frame 6, a front Yoko杆6 d and the longitudinal length of the horizontal member 6 e . The display board 12 on which the exhibits are placed is fixed to the main body frame 6 via the receiving plate 13.

  The front portion of the case body 2 includes a hollow front member 14 that is slightly higher than the display surface, and the front member 14 is provided with a decorative panel 14a. A latch device 15 for holding the upper lid 3 in a closed state is provided in the hollow portion of the front member 14. Although not shown, a claw member that engages with and disengages from the latch device 15 protrudes downward from the tip of the upper lid 3.

The rear end of the display board 12 is located on the front side of the back horizontal rail 6b, and the back partition plate 16 is erected from the rear end of the display board 12, so that the front side of the back partition plate 16 is defined as an exhibition space. The rear space 17 is formed behind the back partition plate 16. That is, the exhibition space 1 and the rear space 17 are partitioned by the back partition plate 16. The upper part of the back partition plate 16 is an inclined part 16a inclined forward in side view, and a left and right longitudinal support frame 18 is fixed to the upper end of the inclined part 16a.

As can be clearly understood from FIG. 3, the upper lid 3 includes a hollow holder portion 3a made of a metal plate constituting the rear portion thereof, and a transparent plate (glass plate) 3b inserted and fixed to the holder portion 3a. The transparent plate 3b is fixed to the holder portion 3a with an adhesive. Reference numeral 3c indicates a spacer. The holder portion 3a is set so that the rear portion thereof is horizontal and the front portion thereof is inclined, and the front end of the holder portion 3a is placed on the support frame 18 in a closed state. A sealing material 19 (see FIG. 2) is provided on the lower surface of the front end of the transparent plate 3b.

  The upper lid 3 is attached to an inverted L-shaped bracket 21 fixed to the back horizontal rail 6b positioned at the uppermost stage so as to be flipped up through a plurality of left and right hinges 22. The opening / closing assist mechanism having the gas cylinder 23, the guide frame 24, the interlocking member (link rod) 25, and the bracket 26 as main elements can be smoothly opened and closed. This point will be described next.

  Two opening / closing assist mechanisms are arranged, and the guide frame 24 has a U-shape with a forward opening in a flat cross section, and is a vertically long reinforcing member 6f fixed to the back horizontal rail 6b (this is also a component of the main body frame 6). It is fixed by welding or screwing. The gas cylinder 23 is arranged in a vertical posture inside the guide frame 24, and a lower bearing portion 27 provided at the lower end of the fixed portion (inner cylinder) 23 a is attached to the guide frame 24 by a first pin 28 that is long in the left and right directions. It is installed so that it cannot move up and down.

Further, the movable portion of the gas cylinder 23 (outer cylinder) in the bearing portion 29 on which is provided at the upper end of 23b is fitted a second pin 32 of the left and right longitudinal, first pair provided in the second pin 32 The guide roller 30 is fitted into a vertically elongated guide hole 31 formed on the left and right side plates of the guide frame 24 so as to be freely rollable. Accordingly, the movable portion 23b of the gas cylinder 23 is held so as to be movable only in the vertical direction.

  The interlocking member 25 is formed in a U-shape with a forward opening in a plane cross section (of course, other shapes may be used), and a second pin 32 is fitted to the lower part of the left and right side plates. The upper bearing portion 29 of the gas cylinder 23 is sandwiched between the left and right side plates of the interlocking member 25. The back portion of the interlocking member 25 is cut out so as not to interfere with the second pin 32 and the upper bearing portion 29.

  In a state where the upper lid 3 is closed, the guide hole 31 of the guide frame 24 extends into the rear space 17 while being positioned slightly below the upper surface of the display plate 12 of the gas cylinder 23.

  A second guide roller 34 is rotatably attached to upper end portions of the left and right side plates of the interlocking member 25 via left and right long third pins 33, while a second guide is provided on the lower surface of the holder portion 3 a of the upper lid 3. A bracket 26 having a longitudinally long slot 35 into which the roller 34 is fitted is fixed by welding or the like. The long hole 35 of the bracket 26 is inclined in a side view so that the rear end is high and the front end is low, and is curved so as to be concave downward and rearward. The upper part of the back plate of the interlocking member 25 is cut out so as not to interfere with the bracket 26.

FIG. 5 shows the movement trajectory of the bracket 26 and the second guide roller 34 accompanying the expansion and contraction of the gas cylinder 23. As can be understood from this figure, when the movable portion 23b of the gas cylinder 23 rises, the second guide roller 34 moves to the front side of the long hole 35 of the bracket 26, and the interlocking member 25 is in front of the closed state. The posture is tilted. Moreover, since the long hole 35 is circular arc shape, the escape of the 2nd guide roller 34 inside the long hole 35 becomes smooth, and the upper cover 3 rotates smoothly.

As can be understood from FIG. 5, the interlocking member 25 rises in the opening process of the upper lid 3 and tilts with respect to the bracket 26 and the gas cylinder 23, so that the interlocking member 25 moves up with almost no change in its posture. Therefore, it is not necessary to increase the depth of the rear space in order to allow the movement of the interlocking member 25. This, by the fact the gas cylinder 23 is not at all interfere with the back partition plate 16 is disposed below the rear space 17, and minimize the depth of the rear space 17, display cases without upsizing A large exhibition space can be secured.

Further, since the second guide roller 34 is positioned at the front portion of the long hole 35 in the bracket 26 in a state where the upper lid 3 is raised, the moment acting on the upper lid 3 by its own weight can be accurately supported ( since the interlocking member 25 is inclined, the pressing force of the vertically downward with respect to the movable portion 23b of the gas cylinder 23 is reduced, in this respect, support functions of the upper lid 3 in the opened state can be said to be high.).

Furthermore, if the gas cylinder is directly attached to the upper lid 3, if the gas cylinder attachment position in the open state is the same as the position A of the second guide roller 34 in the present embodiment, the gas cylinder in the closed state mounting position is a position indicated by reference numeral B in FIG. 5, Then, a stroke of the gas cylinder, yet opening of the upper lid 3 are the same is longer than the present implementation embodiment.

That is, the distance between point A and point C is larger than the distance between point A and point B. As can be understood from this that, according to the present implementation embodiment, it is possible to increase opening and closing the upper lid 3 in a short stroke of the gas cylinder.

If the first guide roller 30 is guided by the guide frame 24 or the like, there is an advantage that it is possible to prevent the bending action from acting on the movable portion 23b of the gas cylinder 23. Guide means of the movable part 23 b of the gas cylinder 23 may be other structures.

  As mentioned above, although embodiment of this invention was described, the specific example of this invention is not limited to this embodiment, It can be embodied variously. For example, the specific structure and form of each member can be selected as necessary. Further, as a means for attaching the upper end of the interlocking member to the lower surface of the upper lid so as to be tiltable and movable back and forth, it is not always necessary to provide a long hole in the bracket, and other structures can be adopted.

It is a perspective view of the display case which concerns on embodiment. It is the schematic sectional side view which showed the one part member by the virtual line. (A) Side sectional view showing the opening / closing assist mechanism of the upper lid, (B) is a sectional view taken along the line BB of (A), and (C) is a sectional view taken along the line CC of (A). FIG. 4 is a partially broken IV-IV view of FIG. It is explanatory drawing (skeleton figure) which shows the function of an opening-and-closing assistance mechanism.
