Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a curing panel device that effectively protects a ground surface, a floor surface, and the like from the action of a concentrated load, and a combination structure of the curing panel device and a moving seat.
[0002]
[Prior art]
  For example, carpets, artificial turf and other laying surfaces, affixing surfaces, etc., where it is necessary to prevent wrinkles, traces, etc. due to the effects of concentrated loads, Protect the carpet by placing plastic plates, metal plates, wood boards, etc. side by side with the operator's manual work on the entire area where there is a risk of acting, while eliminating the risk of concentrated loads. In some cases, it is also common to remove the plastic plate or the like manually by the operator.
[0003]
[Problems to be solved by the invention]
  Therefore, in such a conventional technique, it takes not only a lot of time and man-hours to lay and remove the plate material, but also the laying accuracy of the plate material is likely to be lowered, and the accuracy is lowered. Or, if there is an overlap between the plates due to the way the concentrated load is applied to the plates that are simply laid out side by side, it becomes difficult to pass the concentrated load to the overlapping portion, even if it passes However, even if it is possible, the plate may be damaged, the carpet may be damaged by the edge of the lower plate, and if there is a gap between the plates, the concentrated load There is a disadvantage that carpets and the like are damaged due to dropping out of the gaps.
[0004]
  The present invention has been made as a result of studying as a subject to solve such problems of the prior art, and the object of the present invention is to produce a large number of unit plate materials manually by an operator. It is possible to cover and remove carpets, etc. easily and quickly with less man-hours, without laying and removing, and there is no risk of reducing work accuracy. It is an object of the present invention to provide a curing panel device and a combination structure thereof and a moving bleacher seat that do not cause unexpected overlap or separation between plates due to the manner of action.
[0005]
[Means for Solving the Problems]
  The curing panel device of the present invention is a drum in which one end of a base plate formed by hinge-connecting a plurality of strip-like rigid plate members extending in parallel with each other around a horizontal axis parallel to the strip-like rigid plate member And a means for rotating and advancing and retracting the drum.The rotation and advancing / retreating drive means, a drive roller that rolls on the floor plate, and at least one transmission that frictionally contacts each of the drive roller and the peripheral surface of the base plate wound around the drum, and sometimes the peripheral surface of the drum itself Composed of rollersIt is a thing.
[0006]
  In this device, the drum is rotated under the action of the rotation and advance / retreat driving means, the floor plate wound around the drum is unwound, and the rotation center of the drum is advanced and displaced at a speed according to the unwinding speed. The floorboard can be laid on the floor surface, for example, simply and quickly and always accurately.
[0007]
  And under such a laying state of the floorboard, each rigid board material of which length and width are appropriately selected acts on the passage of the concentrated load on the floorboard and the installation of the concentrated load on the floorboard. Since the concentrated load is distributed to the entire floor surface and transmitted to the floor surface or the like, the occurrence of wrinkles, traces or other damage to the floor surface or the like is sufficiently prevented. In addition, since the laying of the slabs is always properly performed under the hinge connection of the rigid slabs, the overlapping and separation of the rigid slabs is performed regardless of how the load is applied to each rigid board. Can be reliably prevented, and the possibility of breakage of the rigid plate material, damage to the floor surface due to the edge of the rigid plate material, unexpected drop of concentrated load, and the like can be eliminated.
[0008]
  On the other hand, when it is no longer necessary to lay the laying board, the drum is rotated to wind the laying board on its circumference, and the drum itself is retracted at a speed corresponding to the winding speed. By displacing, the floorboard can be easily and quickly removed.
  By the way, in such winding of the floorboard, the winding diameter increases as the number of windings increases. Therefore, in order to cope with the increase in the winding diameter, the width of the strip-shaped rigid plate material is set to the number of windings. Increasing the width gradually is preferable.
[0009]
In addition, in this apparatus, for example, a driving roller rotated by a motor rolls on the floor plate in both cases of laying and winding of the floor plate, and controls each of the rotational movement and forward / backward movement of the drum. Avoiding direct contact between the rollers, traveling wheels, etc., and the floor surface, etc., completely eliminating the possibility of damage to the floor surface, etc. It is possible to effectively prevent a significant increase in rolling resistance such as when moving.
[0010]
Also, here, each of the laying and winding of the laying plate is performed by making the rotational peripheral speed of the drum equal to that of the driving roller with a driving roller and a transmission roller that frictionally contacts each circumferential surface of the drum around which the laying plate is wound. Can be made smooth enough.
In addition, since the driving roller here can also move the drum forward and backward by its rolling motion, both rotation and forward / backward displacement of the drum can be realized by a motor or other driving means.
[0011]
In this case, more preferably, the drum is positively biased in the direction of the transmission roller, thereby sufficiently increasing the respective frictional forces between the transmission roller and the drum side and the driving roller side. Regardless of the winding amount of the base plate on the drum, the occurrence of slip between the contact surfaces is prevented, and the rotational peripheral speed of each member is made sufficiently uniform.
[0012]
  In such a curing panel device, preferably, one end side of the floor plate is detachable directly or indirectly with respect to the drum, and preferably, the other end of the floor plate is connected to the fixing member.
  According to the former, after laying the floorboard, the drum can be separated from the floorboard and put away in a place where it does not get in the way and does not impair the appearance, and according to the latter, the end of the floorboard can be moved unexpectedly. By restraining, each of the laying and winding of the floorboard can be performed more reliably and appropriately.
[0013]
  like thisThe combination of the curing panel device and the moving bleachers is constructed in a nested manner in the curing panel device of any of the above-described forms, and the bleaching seats are developed in a stepped manner on the floor board in the drawer posture. Apply mobile bleachersCan be done byAccording to this, under the condition that the laying plate of the curing panel device is laid on the required ground, floor surface, etc., the telescopic moving seating seat is placed on the laying plate, under the action of the rolling wheels provided on it. It is possible to use the floor surface, etc. that dislikes the effect of concentrated load as the installation surface of the bleacher seat, and in this case, the floorboard, and thus the curing panel device, can be used for the mobile auditorium. Since both the weight of the seat and the spectator acting on the rolling wheel are distributed over a sufficiently wide range and transmitted to the floor surface or the like, the floor surface or the like can be effectively protected from damage.
  Here, the telescoping movable bleachers can be configured such that the chairs are erected on each step portion in the drawer posture.
[0014]
  On the other hand, when the seat is no longer necessary, the movable seat is moved backward from the floor plate to a complete entry posture, and then it is retracted from a predetermined floor surface, etc. In addition to opening the door, the mobile seating area itself can be stored compactly.
  In addition, here, the floor surface and the like can be completely opened by winding the covering plate of the curing panel device on the drum as described above, together with the entering and storing of the moving seat.
  Therefore, according to this combination structure, the mobile bleachers can be easily and quickly deployed and stored, and the ground, floor, etc. can always be effectively protected against the weight of the bleachers and the audience. it can.
[0015]
  Here, the combination structure of the curing panel device and the moving bleachers according to the present invention is any of the above-described structures.The drum and the rotation and advance / retreat driving means of the curing panel device,Constructed in a nesting style, the seats are stepped on the floorboard in a drawer position.Attach it to the stepped frame of the moving bleachersAt the same time, the drive roller of the rotation and advance / retreat driving means is also used as the advance / retreat drive wheel of the stepped part of the moving seat that is pulled out first.
[0016]
  According to this, since it is possible to expand and store the moving seats in synchronization with the laying and winding of the laying plate of the curing panel device, it is possible to further improve the work efficiency and to install these separately. The occupied space can be effectively reduced as compared with the case.
  In addition, it is possible to eliminate the need for special drive means that function only for the deployment and storage of the mobile bleachers, and for the deployment and storage of the floorboard without the special synchronization structure. Can be accurately synchronized.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
  Embodiments of the present invention will be described below.
  FIG. 1 is a perspective view showing an embodiment of a curing panel device according to the present invention in a laying position of a floor board.
  Here, the drum 2 is supported on the apparatus frame 1 so as to be rotatable around a horizontal axis, and one end side of the floor plate 3 is preferably detachably connected to the drum 2 directly or indirectly. Preferably, the other end is connected to the fixing member, for example, by a pin 4.
  Here, the drum 2 can have a general drum structure in which the drum portion is closed over the entire circumference, and the drum portion is provided with a plurality of rod-shaped members extending in the axial direction thereof at intervals in the circumferential direction. A so-called squirrel-cage drum structure can be used.
[0018]
  Further, the floor plate 3 here is configured by hinge-connecting a plurality of rigid plate members 3a having a predetermined length extending in parallel with the horizontal axis that is the rotation center line of the drum 2 at their side portions. The connection of one end of the floor plate 3 to the drum 2 can be performed, for example, by fixing or fixing the rigid plate member 3a located at the end to the drum peripheral surface, It can also be performed by inserting the end rigid plate material 3a into a slit formed by extending in the drum axis direction so that it can be freely inserted and removed. It can be attached and detached.
[0019]
  By the way, as shown in the drawing, in the laying posture of the floor plate 3 having one end fixed or fixed to the drum 2, the drum-side rigid plate material 3a2 is attached to the one rigid plate material 3a1 located on the other end side from the lower edge of the drum 2. The floor plate 3 can be indirectly attached to and detached from the drum 2 by detachably overlapping and connecting with the temporary fixing pins 3b. In particular, according to this, the reconnection of the floor plate 3 to the drum 2 is performed. In this case, the troublesomeness of passing the floor plate 3 below the drum 2 and the rotation and advance / retreat driving means described later can be eliminated.
[0020]
  FIG. 2 is an enlarged exploded perspective view exemplifying this connecting structure, in which the front end portion of the rigid plate member 3a1 located on the other end side of the floor plate 3 is thinned in a step shape from the upper surface side, and the drum The rear end portion of the rigid plate 3a2 positioned on the side is thinned in a step shape from the lower surface side, and the thickness of the thin portions of both the rigid plates 3a1 and 3a2 is set to be another one rigid plate When the thickness 3a and the width w in the same state are substantially equal to the width of the other one rigid plate 3a, the rigid plates 3a1 and 3a2 are mutually connected to the temporary fixing pin 3b. In cooperation with the nut 3b1, it can be connected and disconnected as required.
[0021]
  In such a connection structure, the head of the temporary fixing pin 3b is connected to one rigid plate 3a.2The nut 3b1 and the other rigid plate member 3a.1In the case where the two rigid plate members 3a1 and 3a2 are connected to each other, the temporary fixing pins 3b and the nuts 3b1 can be prevented from projecting to the upper and lower surfaces of the rigid plate members 3a1 and 3a2.
[0022]
  By the way, in order to surely prevent the non-side displacement, movement, etc. of the floor plate 3 separated from the drum side under the above-described connection structure, the anchor 3b2 embedded in advance on the floor surface, etc. The rigid plate material 3a1 is preferably fastened and fixed with screws 3b3.
[0023]
  Here, instead of the connection structure, it is also possible to detachably connect the divided portions of the one rigid plate member 3a divided in the middle in the width direction through a link member or the like.
[0024]
  As shown in FIG. 3, for example, as shown in FIG. 3, the hinge connection of the strip-shaped rigid plate material 3a in the floor plate 3 connected to the drum 2 is performed at both ends of the rigid plate material 3a made of a steel plate, and upwardly facing flanges in the drawing. 3c can be formed by bending each end of each flange 3c in the longitudinal direction to the flange 3c of the adjacent plate member 3a by hinge connection, as shown in FIG. The curved ridges 3d and ridges 3e provided on the respective side portions of the strip-shaped rigid plate material 3a made of an extruded material made of an alloy, a plastic molding material, etc. are connected to each other with the ridges 3e and the ridges 3d of the adjacent plate material 3a. It can also be performed by fitting each of them. Here, each of the curved ridges 3d and the ridges 3e can be formed over the entire length of the rigid plate 3a, or can be formed at a predetermined interval in the length direction.
[0025]
  Here, instead of configuring the entire rigid plate member 3a with aluminum, plastic or the like, as shown in FIG. 4C, only the respective side portions of the rigid plate member 3a are the same as described above. It is also possible to configure the concave strip member 3f and the convex strip member 3g having a fitting structure, and to configure the other portions using a wooden board or the like.
  Further, as shown in FIG. 5, the rigid plate members 3a made of a required material are connected to each other by a strong flexible belt 3h made of synthetic fiber woven fabric or the like, so that the hinges of the strip-like rigid plate members are mutually connected. A connection mode can also be realized.
[0026]
  Further, the apparatus frame 1 shown in FIG. 1 that rotatably supports the drum 2 penetrates through the bearings 5 of the drum 2 and permits the displacement of the bearings 5 and consequently the drum 2 in the vertical direction in the figure. The pair of guide rods 6 are provided, and are arranged around the guide rods 6 in order to bias the bearings 5 and the drums 2 downward in relation to the rotation and advance / retreat driving means of the drum 2 described later. A tension spring 7 is provided.
  Further, this apparatus frame 1 is preferably changed in its posture as required, for example, as shown in FIG.,Alternatively, it includes an external rolling wheel 8 and a grip rod 9 for moving to a required position under the action of an external force while leaving the floor plate 3 laid at a predetermined position.
[0027]
  Here, the posture change of the device frame 1 from the posture shown in FIG. 1 to the posture shown in FIG. 6 is, for example, protruded to the front side of each rectangular frame 1a of the device frame 1 in the state shown in FIG. The grip rod 9 can be rotated by approximately 90 degrees in the direction of the arrow in the figure with the lower one of the two upper and lower rolling wheels 8 as a fulcrum.
[0028]
  By the way, when such a posture change of the apparatus frame 1 is performed, preferably, the posture change on the drum 3 is performed regardless of whether or not the posture change is performed while leaving the floor plate 3 laid at a predetermined position. In order to prevent the rear end portion from being dragged to the floor surface or the like, the rigid plate member 3a located at the rear end is attached to the recumbent member 1b of the apparatus frame 1, for example, as shown in FIG. And it latches with the latching tongue piece 10b.
  The dragging of the rear end portion of the floor plate can also be prevented by directly screwing the rigid plate member 3a located at the rear end to the horizontal member 1b with the temporary fixing pin 10a.
[0029]
  FIG. 7 is a schematic side view showing drive means arranged between the rectangular frames of the apparatus frame 1 to bring about the rotational movement and forward / backward movement of the drum 2 supported thereon, and this drive means is not shown. At least one driving roller 11 that is connected to a motor or the like and rolls on the floor plate is disposed at the lower position of the drum 2 by being supported by the apparatus frame 1 and is in frictional contact with the peripheral surface of the driving roller 11. In the figure, two transmission rollers 12 are also arranged in bearings on the device frame 1 and the drum 2 is placed on the peripheral surfaces of both transmission rollers 12 under the action of the tension spring 7 described above. In addition, it is configured by energizing with a force sufficient to generate a required frictional force.
[0030]
  According to such a configuration, the drive roller 11 and the transmission roller 12 are supported by the apparatus frame 1 with a predetermined inter-axis distance, and therefore, between the peripheral surfaces of the rollers 11 and 12 are expected. As shown in FIG. 7A, the drum 2 that can be displaced under the guidance of the guide rod 6 is in a state in which the floor plate 3 is wound thereon. Of course, the transmission roller 12 is urged with a sufficiently large force under the action of the spring force of the tension spring 7 even in the fully extended state of the floor plate 3 as shown in FIG. Therefore, when the driving roller 11 is driven to rotate in a required direction, the transmission roller 12 is based on the respective frictional force. In the reverse direction and drive drum 2 It can be rotated efficiently both at equal circumferential speed and La 11 in the same direction.
[0031]
  Therefore, when the floor plate 3 laid as shown in FIG. 1 is wound on the drum, the drive roller 11 is connected to the drum 2 in the state where the floor plate 3 is connected to the drum 2 by the temporary fixing pin 3b, for example, as shown in FIG. As shown by the arrow, it is driven to rotate in the right direction, whereby the drive roller 11 supporting the weight of the apparatus is displaced at a predetermined peripheral speed in the backward direction under the action of the frictional force between it and the floor plate 3, The drum 2 is rotated in the same direction as the driving roller 11 through the transmission roller 12 at the same peripheral speed. As a result, the displacement of the drum 2 and the apparatus frame 1 in the backward direction and the winding of the floor plate 3 onto the drum proceed simultaneously and simply, and the drum 2 is shown in FIG. As shown, the other end of the floor plate 3, that is, the rear end of the floor plate 3 is reached, and the winding of the floor plate 3 is finished.
[0032]
  Such winding of the floor board 3 can be performed particularly smoothly when a constant tension is always applied to the floor board 3, and this is the same even when the floor board 3 is laid. As shown in FIG. 7, a tension roller 13 that is always in contact with the inner surface of the base plate 3 and applies a certain tension to the base plate 3 is disposed at an appropriate position of the apparatus, for example, in association with one transmission roller 12. Here, as shown in FIG. 7, tension rollers 13 are disposed at both ends of the “<”-shaped arm portion that pivotally supports the bent portion, and the tension roller 13 here increases the tension of the floor plate 3. It is possible to bias the spring in the direction, and attach a tension roller to the other end of the rod-shaped arm part pivoted at one end, and bias the arm part itself in the direction in which the laying plate tension increases. It is also possible to do.
[0033]
  By the way, the device that has finished winding the floor plate 3 is used to replace the floor plate 3 with the same one.placeIn the case of repeatedly laying and winding in step 3, for example, the pin 4 that connects the rear end portion of the floor plate 3 to the fixing member can be kept in that state while maintaining the winding end posture. Then, when the device is moved to another place for storage, the pin 4 is removed to release the floor plate 3 from the fixing member, and the rigid plate member 3a at the end is used, for example, as described with reference to FIG. The temporary fixing pin 10a and the engaging tongue piece 10b are hooked on the horizontal reed member 1b of the device frame 1, and then the entire device frame 1 is set in a rotating posture shown in FIG. Transport to position.
[0034]
  On the other hand, when laying the floor plate 3 wound on the drum of the apparatus, the apparatus frame 1, and thus the entire apparatus is in the posture shown in FIG. 8, and preferably the apparatus frame 1 is engaged with the recumbent member 1b. After the rear end of the floor plate 3 is connected to the fixing member by the pin 4, the driving roller 11 is rotated leftward on the floor plate as indicated by an arrow in FIG. Further, the displacement of the drum 2 in the advancing direction and the rotation of the drum 2 in the same direction as the driving roller 11 at the same peripheral speed are provided, and the floor plate 3 is simply and quickly laid down accurately at all times. . FIG. 1 is a diagram showing a completed state of the laying plate 3, and in the laying posture of the laying plate 3 as shown here, when the apparatus frame 1 and the drum 2 are in the way, As described above, the temporary fixing pin 3b is removed to separate the installed laying plate 3 from the drum 2, and the device frame 1 is disturbed by the action of the rolling wheels 8 under the changed posture as shown in FIG. Move to a place where it doesn't get lost and look good.
  In this case also, preferably, the rigid plate member 3a at the rearmost end of the floor plate portion remaining on the drum side is hooked and supported on the side wall portion 1b as shown in FIG.
  Thus, according to this curing panel device, both the laying and winding of the floor plate 3 can be performed both simply, quickly and accurately.
[0035]
  FIGS. 9 and 10 are a side view and a schematic plan view showing an embodiment of the combined structure of the curing panel device and the telescoping moving bleaching seat as described above, in the pulling-out posture of the moving bleaching seat.
  Here, as a matter of course, the curing panel device and the moving bleacher can be separated from each other and configured separately, but more preferably, the drum of the curing panel device and each of the rotation and advance / retreat driving means are provided. Instead of the above-described apparatus frame 1, it is attached to the frame of the stepped portion that is pulled out first of the moving viewing seat, and more preferably, in addition to this, the driving roller of the rotation and advance / retreat driving means is moved It also serves as a step forward / backward drive wheel that is pulled out first in the seat.
[0036]
  The figure shows this optimal form, which can roll the rolling wheels 22 on each side of the mobile auditorium 21 having a telescopic structure on each floor plate of a pair of curing panel devices. It is something that has been conditioned. Here, for example, as is apparent from the enlarged perspective view of the portion A of FIG. 10 shown in FIG. 11, the rolling wheel 22 is provided below the support 23 a of the frame 23 of each stepped portion of the telescopic structure. In the place where the horizontal beam 23b projecting forward is provided, there are three at the lower portion of the support post 23a, and one at the tip of the horizontal beam 23b, as is apparent from FIG. Are arranged respectively.
[0037]
  Here, the rotating and advancing / retracting drive means are attached to the stepped frame 23 of the movable observation seat 21 which is withdrawn first. The bracket 24 projecting from the tip of the horizontal beam 23b is attached to a pair of two. The shaft driving roller 11 is supported by a bearing, and the driving roller 11 is connected to a motor 25 (see FIG. 10) so that it can be driven in a required direction, and is in frictional contact with each driving roller 11. A pair of transmission rollers 12 similar to those described above are also supported by bearings on the bracket 24. The drum 2 is attached to each pair of the arm 23d that projects horizontally from the upper end of each of the support post 23a and the additional support post 23c to the front side and the pair 5 penetrating the bearing 5 of the drum 2. The guide rod 6 is provided, and each bearing 5, and consequently the drum 2, is biased downward by a compression spring 26 disposed on the guide rod.
[0038]
  According to such a configuration, the drive roller 11 functions as a rolling wheel on the distal end side of the frame 23 having the lowest height, which is pulled out first, and directly of the frame 23. Indirectly, it also functions as a forward / backward drive wheel for all the frames 23. That is, in the drawing posture of all the frames 23 as shown in FIGS. 9 and 10, the seats are developed stepwise on the floor board 3, and all the chairs 27 are erected on each step portion. When the drive roller 11 is rotated clockwise as shown in FIG. 7 (a) in addition to the chair 27 lying down in the state, the drum 2 rotates as described above. The first frame 23 is also moved backward based on the backward displacement of the drum 2. When the frame 23 comes into contact with the next frame 23 in the backward direction, this frame 23 is also moved backward in addition to the first frame 23, and all the frames 23 are sequentially started to move backward in the same manner. Eventually, when the drum 2 reaches its retracted end position where all of the floor plate 3 has been wound there, all the frames 23 are completely moved into the other frame 23 as shown in FIG. Thus, the curing panel device is also housed in a compact manner together with the moving seat 21.
  In the figure, reference numeral 28 denotes a housing disposed at the storage position of the movable seat 21, and reference numeral 29 denotes a front plate provided upright in front of the first frame 23.
[0039]
  On the other hand, the unfolding of the mobile seat 21 is performed by rotating the driving roller 11 counterclockwise as shown in FIG. 7B under the retracted state as shown in FIG. In this case, the sequential withdrawal of the rear side frame 23 following the earliest frame 23 can be performed by, for example, as shown in FIG. 11, a hook piece 30 provided at the front end of the horizontal beam 23b of the rear side frame 23. When the advance amount of the side frame 23 reaches a predetermined amount, it can be performed by engaging with the support 23a.
[0040]
  Thus, according to this combined structure, the floor surface and the like can be effectively protected by sufficiently dispersing the weights of the moving seat 21 and the audience with the floor plate 3, and of course, with the operation of the driving roller 11, The laying and winding of the floor plate 3 based on the rotation and forward / backward displacement of the drum 2 and the deployment and storage of the movable seat 21 can be performed extremely efficiently and accurately.
[0041]
【The invention's effect】
  Thus, according to the curing panel device of the present invention, the laying and winding of the floorboard can be performed simply and quickly and accurately, and the possibility of damage to the floor surface and the like can be more effectively removed.
  In addition, according to the combination structure of the present invention, it is possible to install a bleacher seat on a floor surface or the like that could not be installed in the past, and it is also easy and quick to deploy and store a mobile auditorium. Can be done.
