Description

  The present invention relates to a built-in display case installed in a museum or the like. More specifically, the door made of glass or the like disposed in the opening of the case body is moved in the thickness direction of the case, while the front door of the door is moved. The present invention relates to a structure of a door device in an exhibition case that is opened and closed by moving in a direction.

  The applicant of the present application previously described, in Patent Document 1, the front surface (opening) of the case body in the display case installed in a museum or the like is arranged side by side with a plurality of transparent doors made of glass or the like. And at least one of the doors is shifted in the thickness direction to the front of the case body to leave an arrangement interval with other doors arranged side by side, and then translated in the width direction. In the display case in which the front surface of the case main body is opened, the fitting body has a fitting groove that is open on the upper surface of the support frame that supports the door so as to expand toward the back of the case main body. Is attached to a moving block provided so as to be movable back and forth with respect to a fixed frame positioned behind the support frame at the sealing position of the door (the position when the case body is sealed, hereinafter the same). Positioning engagement body that can be fitted into the groove It disclosed a structure for mounting a drive actuator for longitudinal movement of the moving block.

  The configuration of the fitting groove and the positioning engagement body is a position regulating means for regulating the door to a sealed position, whereby the positioning engagement body is advanced in the thickness direction of the door and the fitting is performed. When fitted in the mating groove, the support frame and thus the door can be prevented from moving left and right (moving in the frontage direction), and the door can be positioned in a sealed position.

  However, when sealing with the above configuration, the moving block is moved back and forth by the drive actuator when the door is pulled back in the thickness direction of the door with respect to the door previously pulled into the opening of the case body. Therefore, since the positioning engagement body is fitted into the fitting groove, the position restricting means must be provided on both the case main body side and the door side, resulting in a complicated structure.

  Prior to positioning the positioning engagement body in the fitting groove and positioning the door in the sealed position, an operator moves the door so that the positioning engagement body can fit in the fitting groove. However, since the stop position of the door at this time has to be adjusted by an operator, there is a problem in that it takes time to adjust this position.

  In order to solve such a problem, the applicant of the present invention in JP-A No. 2004-151650, at least one glass plate door or the like disposed in the opening of the case body of the display case is parallel to the thickness direction of the door. And a guide supporting means for supporting the opening so as to move in parallel with the opening direction of the opening, and a closed position corresponding to a sealed position when the door is sealed with respect to the case body (Position stop means for restricting the stop position in the left-right direction of the door in the previous stage of the sealing operation to the closing position), and the position restricting means is for closing positioning of the door provided on the door side. An engagement projection for positioning, a positioning engagement body that is provided on the guide support means side so as to be rotatable in the frontage direction, and engages and disengages with respect to the engagement projection, and the rotation posture of the positioning engagement body is regulated. And posture control means for It proposed Rukoto.

  However, in the configuration of Patent Document 2, since the positioning engagement body itself can rotate in the frontage direction, the door may move in the frontage (left / right) direction with respect to the guide support means (the closing position is shifted). Therefore, when the door is moved in the sealing direction with respect to the case main body through the guide support means, there is a problem that it is uncertain that the door fits in the sealing position with respect to the case main body.

  According to the present invention, in a state in which the door is regulated at a predetermined position (closed position) with respect to the guide support means, the guide means and the door are closed at the previous stage for sealing the case body. It is an object to provide an exhibition case that can be stopped reliably.

  In order to solve this technical problem, the display case of the invention according to claim 1 is configured such that at least one glass plate door or the like disposed in the opening of the case body is parallel to the thickness direction of the door. In the display case comprising: guide support means for supporting the door so as to move in parallel with the opening direction of the opening after movement; and position restriction means for restricting the door to a closed position. The restricting means is an engagement protrusion provided on the door side for positioning and closing the door, and a positioning means provided on the guide support means side so as to be rotatable in the frontage direction and engaged with and disengaged from the engagement protrusion. On the other hand, when the door is moved so as to be sealed in the opening, it is brought into contact with the positioning engagement body. Engagement of the positioning engagement body Posture locking means for holding the posture in which provided on the case body side.

  According to a second aspect of the present invention, in the display case of the first aspect, the positioning engagement body is formed in a substantially fan shape when seen in a plan view, and the engagement protrusion is fitted to the circumference of the circle. An engagement recess is provided, and the posture locking means has a pair of contact arms for contacting a pair of side edges extending in the radial direction of the positioning engagement body.

  According to a third aspect of the present invention, in the display case according to the second aspect, the abutting portions of the pair of abutting arms invite the pair of side edges extending in the radial direction of the positioning engagement body. , Are formed so as to expand forward toward the positioning engagement body.

  Furthermore, the invention according to claim 4 is the display case according to any one of claims 1 to 3, wherein the case main body has a driving means for forcibly moving the door in parallel with the thickness direction thereof. It is equipped with.

  According to the first aspect of the present invention, if the door is stopped at the closing position for sealing the door against the case body by the position restricting means, the door is brought close to the opening. When the seal is closed, the posture locking means abuts on the positioning engagement body engaged with the engagement protrusion, and automatically and surely holds (locks) the position of the positioning engagement body in a non-rotatable manner. be able to. Since the posture locking means is only provided at the opening on the case body side, the structure becomes extremely simple and the manufacturing cost can be reduced.

  According to the configuration of the invention described in claim 2, the positioning engagement body is formed in a substantially fan shape in a plan view, and an engagement recess into which the engagement protrusion is fitted is provided on a circumferential edge thereof. The posture locking means has a pair of contact arms for contacting a pair of side edges extending in the radial direction of the positioning engagement body.

There is an effect that can be done.

  According to the configuration of the invention described in claim 3, in addition to the effect of the invention described in claim 1 or 2, the contact portions of the pair of contact arms are arranged in the radial direction of the positioning engagement body. In order to draw in the pair of extending side edges, it is formed so as to spread forward toward the positioning engagement body, so that it can be horizontally rotated by a pair of opposing abutment portions that are guide portions. Since the posture of the positioning engagement body is locked, the accuracy of the sealing position is improved.

  According to the configuration of the invention described in claim 4, since the case main body is provided with the driving means for forcibly moving the door in parallel with the thickness direction thereof, even a heavy door can be easily lightened. There is an effect that it can be opened and closed.

  Embodiments of the present invention will be described below with reference to the drawings (FIGS. 1 to 11). Reference numeral 1 denotes a case main body such as an exhibition case in the present embodiment, and fixed frames 2 and 2 are arranged on the same vertical plane on the upper and lower portions on the front side (opening 1a side). .

  The doors 3 and 3 are arranged by a surface plate 3a made of a transparent glass plate or the like, which is arranged flush and can seal the opening 1a of the case body 1, and a guide rail 11 as an upper and lower edge frame made of an aluminum extruded member or the like. It is configured. The door 3 is configured by being fixed to the back surface of the upper and lower edge portions of the surface plate 3a and the front surface of the guide rails 11 and 11 having a substantially E-shaped section in the left and right direction through an adhesive 13 made of silicon resin or the like.

  The upper and lower portions of each door 3 are attached to fixed frames 2 and 2 provided on the upper and lower portions of the opening 1a in the case main body 1 through a guide support means 4 described later, respectively, so as to be movable left and right and back and forth. . That is, after the doors 3 are moved by the guide support means 4 and 4 in parallel with each other in the thickness direction (the front-rear direction approaching and separating from the opening 1a, hereinafter may be referred to as the front-rear direction). It can be translated in the width direction (the left-right direction along the opening 1a, hereinafter sometimes referred to as the left-right direction or the frontage direction).

  In the state where the opening 1a of the case body 1 is closed at each door 3, the surface plate 3a of each door 3 is positioned on the same vertical plane and is in close contact with the packing 6 provided on the periphery of the opening 1a. Thus, the case body 1 is sealed. On the other hand, when the doors 3 are opened from the state where the doors 3 are flush with each other, the doors 3 are moved forward by a predetermined amount with respect to the surface in close contact with the packing 6.

  Further, in order to operate each door 3 in the front-rear direction, the case body 1 is provided with drive means (details will be described later) in association with the guide support means 4.

  These guide support means 4 are formed vertically symmetrically with respect to the upper and lower portions of each door 3 and have basically the same configuration regardless of the mounting location (see FIG. 2). Therefore, the guide support means 4 located on the lower side of one door 3 will be described in detail below as a representative.

  The guide support means 4 includes a plurality of sliding blocks 7 bolted to the upper surface of the fixed frame 2 at appropriate intervals (in the embodiment shown in FIG. Then, two are shown on the upper and lower sides of one door 3), a sliding shaft 7 a fitted to each sliding block 7 so as to be slidable back and forth, and fixed to the tip of each sliding shaft 7 a. The left and right longitudinal support frame 9 and a plurality of vertical rolling rollers 10 attached to the front surface of the support frame 9 (side surface on the opening 1a side of the case body 1) and supporting and guiding the guide rail 11 (Refer FIG.1, FIG.2, FIG.3 and FIG.6).

  As shown in FIG. 2, a plurality of vertical rolling rollers 10 are attached to the front surface of the left and right longitudinal support frame 9 fixed to the tip of each sliding shaft 7a. Of the left and right long fitting grooves 11a and 11b opened on the rear surface side of the guide rail 11, it is configured to fit into a fitting groove 11a as a lower guide groove. When the vertical rolling roller 10 rolls on the upper and lower inner surfaces of the fitting groove 11a, the door 3 is supported so as to be slidable left and right.

  In addition, about the structure which makes the guide rail 11 slidable right and left, it is not restricted to an above-described form, For example, between the support frame 9 and the guide rail 11, many balls hold | maintained by the retainer so that rotation is possible. Suspension means (not shown) may be employed that are inserted in a line so that the guide rail 11 can slide to the left and right with a light force.

  The drive means is provided for each door 3, and has one operation section 30 for each door 3, and at least one upper and lower operation sections 31 and 31. In the form (FIGS. 1, 4 to 8), two operation unit cases 33 are appropriately separated on the front surface of the base frame 32 below the lower fixed frame 2 out of the upper and lower fixed frames 2, 2 of the case body 1. Fix with bolts, nuts, etc. (see FIGS. 1 and 4). In the operation portion case 33, an operation shaft 34 and four driven shafts 35 are rotatably arranged at the center via bearings 36. The large gear 40 that rotates integrally with the operation shaft 34 has each driven shaft. The small gear 41 fixed to 35 is meshed with each other, and the four driven shafts 35 are synchronized with one operating shaft 34 and rotated in the same direction (see FIG. 5). A front end portion (square shaft portion) 34 a of the operation shaft 34 is protruded from the front surface of the operation portion case 33. Note that the operation unit case 33 and the operation shaft 34 are covered with a baseboard 32 that can be turned up and down so that they are not normally visible from the front of the display case. After tilting (see FIG. 1), an operation handle 38 such as a round handle is attached to the front end portion (square shaft portion) 34a and rotated.

  At the rear end of each driven shaft 35, the tip of a wire 42 for transmitting a rotational force to each actuating portion 31 described later is inserted and detachably connected via a connection set screw 43. The guide block 44 fixed to the rear plate of the operation unit case 33 is inserted with an end of a flexible outer tube 45 fitted on the outer periphery of the wire 42, and the end of the outer tube 45 is fixed to a predetermined length. By making it coincide with the axis of the driven shaft 35 (see FIG. 4), it is ensured that the rotation of the wire 42 on the inner diameter side can be performed smoothly. These outer tubes 45 with wires 42 are piped into the case body 1 (see FIG. 1).

  At least one actuating portion 31 is arranged with respect to the upper and lower portions of each door 3 (in the embodiment, two at an appropriate interval along the longitudinal direction). That is, as shown in FIGS. 6, 7, and 8, a pair of front and rear support blocks 47, 47 are erected on the base 46 fixed to the upper and lower fixed frames 2 with bolts or the like. , 47 and a pair of left and right guide shafts 48, 48 are arranged, and a screw shaft 49 is arranged between them so as to be rotatable only through bearings provided on both support blocks 47, 47. Both ends of the moving block 50 screwed to the screw shaft 49 are slidably fitted to the pair of guide shafts 48, 48. A locking piece 53 is formed by bending the distal end of a coupling body 52 whose base end is fixed to the moving block 50 with a screw 51, and the locking piece 53 is loosely inserted into a rectangular locking hole 54 formed in the support frame 9. Fit. The other end of the wire 42 is inserted into the base end portion of the screw shaft 49 and connected through a connection set screw 55. The other end of the outer tube 45 loosely fitted to the wire 42 is inserted into a guide block 56 fixed to one support block 47, and the end of the outer tube 45 is aligned with the axial center of the screw shaft 49 by a certain length or more. (See FIG. 7 and FIG. 8) to ensure that the inner diameter side wire 42 can be smoothly rotated.

  In the drive means, instead of the configuration in which the door 3 is manually moved back and forth as described above, a drive motor or other drive actuator that can rotate forward and backward may be used.

  Next, a description will be given of the configuration of the position restricting means 22 for stopping and restricting each door 3 in advance at the closing position with respect to the opening 1a when the doors 3 are moved along the frontage direction. The position restricting means 22 is provided on each guide support means 4. In this embodiment, as shown in FIGS. 2, 3, 7, 9, and 10, the position restricting means 22 is arranged with respect to the top and bottom of each door 3. Since these are formed symmetrically in the vertical direction, those arranged on the upper side of one door 3 will be described in detail below.

  The position restricting means 22 is one of the fitting grooves 11a and 11b in the guide rail 11 (the upper fitting groove 11b for the upper guide rail 11 and the lower guide rail 11). And a plurality of engagement pins 23 provided in the lower fitting groove 11b) at appropriate intervals in the longitudinal direction, and the upper surface of the support frame 9 at the upper position (the lower surface of the support frame 9 at the lower position) A positioning engagement body 24 that is rotatable in a horizontal plane and is engaged with and disengaged from the engagement pin 23 in a state of being sandwiched by the engagement groove 11b, and protrudes upward on the rear surface of the support frame 9 and presses forward. And an elastic piece 25 to be urged.

  The positioning engagement body 24 and the elastic piece 25 are provided in the number corresponding to the engagement pins 23 as the engagement protrusions (both are two for each door 3 in the embodiment shown in FIG. 9). .

  In addition, the fitting groove 11b in this embodiment does not need to be formed in a groove shape, for example, is formed in a stepped shape in a side view, and a plurality of engaging pins 23 are protruded upwardly with appropriate separation in the longitudinal direction, You may comprise so that the positioning engagement body 24 may pass through on the said step-shaped part, and it may rotate right and left. Further, the positioning engagement body 24 and the elastic piece 25 may be attached to the guide rail 11 and the engagement pin 23 may be attached to the support frame 9.

  As shown in FIGS. 9 and 10, the positioning engagement body 24 that is formed in a substantially fan shape and rotates left and right while being sandwiched between the fitting grooves 11b is an elastic piece when the door 3 is positioned at the closed position. 25, an engagement recess 24b formed in the central portion of the substantially arc peripheral portion of the turning radius R0, and a predetermined length L on both left and right edges of the substantially arc peripheral portion. Rotation restricting portions 24c, 24c formed in a straight line, and shoulder portions (right and left side edges extending in the radial direction of a substantially fan shape) formed between the contact portion 24a and the rotation restricting portions 24c, 24c. It is comprised by. The position restricting means 22 is not limited to being vertically symmetrical with respect to the top and bottom of each door 3 as in the present embodiment, but is disposed only on one of the upper and lower portions of each door 3. You may be made to do.

  Next, a description will be given of the posture locking means 60 according to the present invention, in which each door 3 fits snugly into a predetermined position (sealing position) of the opening 1a of the case main body and can be sealed. In the first embodiment, as shown in FIGS. 2, 3, 11 (a) and 11 (b), a positioning unit engaged with each engagement pin 23 is provided on the front surface of the fixed frame 2. A pair of left and right contact arms 61 and 61 for holding and locking the combined body 24 are provided so as to extend from the base 62 forward and horizontally. Further, the pair of left and right contact arms 61 and 61 and the positioning engagement body 24 are arranged at the same height position. The base 62 is fixed to the front surface of the fixed frame 2 via a bolt 63. As shown in FIGS. 3 and 11A, the contact portion 61 a that is the tip of the pair of contact arms 61, 61 is a positioning engagement body when the support frame 9 moves backward and approaches the fixed frame 2. From the back side of 24, it is formed in the shape of the front spreading | diffusion toward the back of the positioning engagement body 24 so that it may approach and contact | abut to a pair of shoulder parts (right-and-left both-sides edge extended in the radial direction) 24d and 24d. It is what. In other words, when the support frame 9 is retracted and approaches the fixed frame 2 (when the door 3 is retracted to a predetermined sealing position), the pair of contact arms 61 and 61 are opposed to each other in plan view. The left and right side edges 24d, 24d on the back side of the positioning engagement body 24 are guided by the portion 61a, and the posture of the positioning engagement body 24 engaged with the engagement pin 23 is locked. Therefore, the number of the posture lock means 60 is provided corresponding to the arrangement position of the positioning engagement body 24.

  With the above configuration, the door 3 (including the guide rails 11, 11) can move to the left and right with respect to the guide support means 4. Even if it can be fixed, when the door 3 is sealed, the pair of left and right side edges 24d, 24d of the positioning engagement body 24 engaged with the engagement pin 23 by the pair of abutment arms 61, 61 of the posture lock means 60. The positioning engagement body 24 can be held (locked) in a non-rotatable position, and the door 3 can be accurately set at a predetermined sealed position with respect to the case body 1 without rattling in the frontage direction. It is.

  In particular, in this embodiment, when the positioning of the door 3 by the position restricting means 22 is incomplete (when the positioning engagement body 24 is slightly shaken), only the presence of the pair of contact arms 61 and 61 on the case body 1 side is present. Thus, the positioning of the door 3 to the predetermined sealing position at the opening 1a can be performed with extremely high accuracy.

  Next, other configurations adopted in the present embodiment will be described.

  In the present embodiment, each guide rail 11 is fixed to the upper and lower portions of each door 3 via an adhesive 13, but the upper and lower portions of each door 3 and the guide rail 11 are bonded by the adhesive 13. In order to hide (hide) the packing 6 provided on the periphery of the opening 1a in the case body 1 through the transparent door 3, a coating film 12 is applied or a sheet or the like is applied to a corresponding portion of each door 3 (See FIG. 1 and FIG. 2).

  At this time, since the adhesive 13 is filled on the back side of the coating film 12 or the sheet, each guide rail 11 is provided with a claw-like ridge 11c as a safety measure to prevent the door 3 from being accidentally dropped. It protrudes in the front direction of the main body 1 (see FIG. 2).

  Further, guide rollers 19 are respectively attached to the support frames 9, 9 at the upper and lower portions of the opening 1 a in the case body 1 via connecting metal fittings 18 screwed to the rear surface of the support frames 9. Each of the doors 3 is attached so as to abut against the guide rails 11, thereby preventing the doors 3 from swinging in the front-rear direction (see FIG. 2).

  In the display case and the door device configured as described above, the operation of opening and sealing each door 3 and the lateral movement stop by the position restricting means 22 and the sealing positioning by the attitude locking means 60 at that time will be described. . Here, the guide support means 4, 4, drive means and position restricting means 22, and posture lock means 60 installed on the upper and lower sides of one door 3 are configured to perform the same operation vertically. Therefore, hereinafter, the operation of the one arranged on the upper side of one door 3 will be described in detail as a representative.

  First, the baseboard 37 shown in FIG. 1 is opened so that the operation unit 30 shown in FIG. 4 appears, and the operation handle 38 is inserted into the front end portion 34a of the operation shaft 34 and rotated in a predetermined direction (clockwise). As a result, the four wires 42 per one operation unit 30 are simultaneously rotated in a predetermined direction. In each actuating portion 31, when the screw shaft 49 is rotated clockwise (rightward) via the wire 42, the moving block 50 moves forward, so that the locking piece at the tip of the connecting body 52 attached thereto is moved. 53 pushes the support frame 9 forward through the locking hole 54, and as shown in FIG. 7, the door 3 is pushed forward by a predetermined distance S (the direction in which the door 3 separates from the opening 1a), and the case 3 The main body 1 is opened.

  Next, when the door 3 is slid in the left-right direction from the state in which the door 3 is positioned at the closed position (see the state of FIG. 10A), the door 3 is engaged in the right direction. The engaging pin 23 that has been locked in the recess 24b moves to the right to rotate the positioning engagement body 24 to the right, and the engaging pin 23 moves away from the engaging recess 24b (FIG. 10). (See (B)). At this time, although not shown, the two positioning engagement bodies 24 and 24 provided on the fixed frame 2 on the upper side of the case main body 1 perform the same operation.

  When the door 3 is further slid rightward, the positioning engagement body 24 is engaged with the left shoulder 24d of the positioning engagement body 24 rotated so that the opening of the engagement recess 24b faces the right side. The engaging pin 23 located behind the stopped engaging pin 23 collides and is prevented from passing (see FIG. 10C).

  Here, in the positioning engagement body 24 shown in FIG. 10C, the right shoulder portion 24d abuts against the elastic piece 25 and is pressed and urged forward, and the left and right rotation restricting portions 24c and 24c. Since the turning radius R1 is larger than the turning radius R0 of the substantially arc-shaped portion in the positioning engagement body 24, when the left turning restricting portion 24c passes while turning, it is supported by the fitting groove 16, so that FIG. The positioning engagement body 24 is prevented from rotating to the right beyond the posture shown in FIG.

  On the other hand, to stop the door 3 at the closed position, first, the door 3 is slid leftward from the state shown in FIG. Then, in response to this, the engagement pin 23 moves to the left and engages with the engagement recess 24b in the left positioning engagement body 24, thereby rotating the positioning engagement body 24 to the left (see FIG. 10B). ). Further, when the door 3 is slid leftward and the positioning engagement body 24 is rotated leftward, as shown in FIG. 10A, the contact portion 24a contacts the elastic piece 25 and presses forward. As a result, the positioning engagement body 24 is turned to the left, and the sliding of the door 3 in the left direction is stopped.

  Therefore, by attaching at least one position restricting means 22 to the guide support means 4 so that the door 3 is in the closed position when the position restricting means 22 is in the state shown in FIG. 9 and FIG. There is an effect that it is extremely easy to stop 3 at the closed position. Further, since the position restricting means 22 is constituted by the engaging pin 23, the positioning engaging body 24, and the elastic piece 25, the structure thereof is extremely simple, and the manufacturing cost can be reduced.

  After the door 3 is positioned at the closed position, the operating handle 38 in the operating unit 30 is rotated in the opposite direction to rotate the screw shaft 49 of the operating unit 31 through the plurality of wires 42, and FIGS. As shown in FIG. 3, the support frame 9 and thus the door 3 are pushed rearwardly (in a direction in which the door 3 approaches the opening 1a) by a predetermined distance S, and the back surface is pressed against the packing 6 as shown in FIG. The case body 1 is sealed.

  At this time, the engagement pin 23 is engaged with the contact portions (leading portions) 61a, 61a on the distal end side of the pair of contact arms 61, 61 of the posture lock means 60 provided on the fixed frame 2 of the opening 1a in the case body 1. Since the pair of left and right side edges 24d and 24d of the positioning engagement body 24 in the state of being engaged with each other are attracted and contacted (see FIGS. 11A and 11B), the lateral movement of the guide rails 11 and 11 is completely performed. And can be accurately stopped at the sealed position.

  It is needless to say that the door device in the display case of the present invention does not need to be configured so that all the openings can be opened, and a part of the door device may be a fixed door using this configuration.

  The present invention is not limited to the above-described form and can be embodied in various forms. In the present embodiment, the two doors 3 that seal the front side of the case body 1 are arranged. However, the present invention is not limited to this, and the door 3 may be configured to be sealed by a single door. You may comprise so that it may seal with a door. Moreover, if the door apparatus in this invention has an opening part, it can be installed not only in the front side of the case main body 1, but in any surface of four directions.
