Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a storage tent such as a slide-type opening / closing tent that can expand and contract in a bellows-type, and in particular, when applied to a sliding-type opening / closing tent, eliminates the load on the tent hem during expansion and contraction and The present invention relates to a sealing mechanism that can eliminate fluttering and can block the atmosphere between the storage space and the outside.
[0002]
BACKGROUND OF THE INVENTION
  A slide-type open / close tent that is particularly suitable for applying the present invention is used as a structure such as a warehouse on the ground, and is further used as a cover for a cargo bed of a vehicle such as a truck or a trailer. In such a slide-type opening / closing tent, a plurality of, for example, gate-shaped movable frames including a drive frame are connected to and separated from each other via a relay member formed of a pantograph-like link and the like. A fixed luggage storage space is formed by the tent body in a state where the body is supported and the movable frames are expanded from each other.
[0003]
  Such a sliding open / close tent has a tent hem that fluctuates due to wind from the outside because the hem of the tent body (hereinafter referred to as the tent hem) hangs down in an unfixed state due to the movable frame's detachability. It was inevitable that this would occur, and the barrier between the storage space and the outside was not sufficient. Such a barrier property is particularly strictly required when, for example, the rolled steel material immediately after rolling is transported by sea. When salt moisture adheres due to the inflow of sea breeze into the storage space, the rolled steel material is heated at a high temperature. This is because rust is likely to occur.
[0004]
  Therefore, in order to ensure the shielding between the storage space and the outside atmosphere, a curtain rail is attached to the base frame, and runners attached to multiple locations on the tent hem are slidably fitted to the curtain rail. However, there are some cases that prevent the tent hem from fluttering and ensure the barrier between the storage space and the outside, but it is inevitable that the tent hem will be stressed during expansion and contraction. If this is not performed smoothly, the tent hem may be broken, leaving room for improvement in terms of durability.
[0005]
[Technical issues for which development was attempted]
  The present invention has been made in consideration of such a background, and does not apply a load to the tent hem during expansion / contraction, eliminates fluttering of the tent hem during expansion, and ensures the atmosphere between the storage space and the outside.

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1
  The sealing mechanism of the present invention will be specifically described below based on the illustrated embodiment. The configuration of the sliding opening / closing tent T, which is an example to which the sealing mechanism is applied, is not limited to this, but the tent frame 2 is attached to the base frame 1 by the drive mechanism 3 so as to be freely opened and closed. The tent body 4 is provided so as to cover the tent body 4.
  First, the base frame 1 is substantially integrated with the loading platform 11 of the vehicle 10 in the embodiment shown in FIG. 1, and the leg portion 1A is fixed to the loading platform 11 side by welding, bolting or the like. Of course, the base frame 1 does not need to be integrated with the loading platform 11 and may be removable.
[0012]
  At that time, for example, the leg portion 1A of the base frame 1 is set to a length slightly lower than the height of the loading platform 11 of the vehicle 10, and when the vehicle is mounted on the vehicle 10 and moved, a separate fastening member is provided on the base frame 1. Pallet type that can be mounted and fixed to the vehicle 10 in other cases, lifted up by an outrigger, crane, forklift, jack, etc., removed from the vehicle 10 and placed on the ground such as a parking lot, container-mounted It can also be configured as a sliding slide tent T of the type. Of course, depending on the type of lift-up, the length of the leg 1A is appropriate, and only the base frame 1 without the leg 1A may be used.
[0013]
  The tent frame 2 supported with respect to the base frame 1 as described above will be described below. This is provided with an end frame 20 at the front end of the loading platform 11 and a movable frame 21 closer to the rear than this. The movable frame 21 includes a movable intermediate frame 22 and a drive frame 23 on the rear end side. The movable intermediate frame 22 and the drive frame 23 constituting the end frame 20 and the movable frame 21 are both gates as an example. Forming the shape, and as an example, they comprise a wheel 22a rolling on the rail 12 and a drive wheel 23a at the lower end.
  Incidentally, the frame element described in claim 1 refers to an element that substantially comprises the tent frame 2, which is composed of the end frame 20 and the movable frame 21.
  The movable frame 21 is provided with, for example, an X-shaped pantograph-shaped relay link rod 24 between the movable intermediate frame 22 and the drive frame 23, and this has a fixed pivot 25 attached to the movable frame 21. A configuration is adopted in which the upper portion and the lower portion are allowed to be displaced in the vertical direction with the slide pivot 26 as the lower portion. Reference numeral 24 a denotes an intersection pivot of the relay link rod 24.
[0014]
  Further, the movable frame 21 supports an auxiliary support frame 27. As shown in FIG. 2, for example, this movable frame 21 extends the upper end of the relay link rod 24 in a straight line upward to adjoin the relay. The link rod 24 is pivotally connected at the upper end, thereby reducing the sag size when the tent body 4 is contracted, thereby ensuring a sufficient cargo space (height). The auxiliary support frame 27 is constructed by extending the upper end of the relay link rod 24, but a link mechanism or the like may be provided separately.
[0015]
  As will be described later, the auxiliary support frame 27 prevents the tent body 4 from drooping when the tent body 4 is contracted, and waits at a somewhat lowered position when the tent body 4 is extended. The standby position is determined in consideration of the hanging position when the tent body 4 is supported.
  In addition to such an embodiment, as a structure for preventing the tent body 4 from sagging when the tent body 4 is contracted, the auxiliary support frame 27 can be formed as a two-pronged double rod.
[0016]
  Next, the drive mechanism 3 for such a tent frame 2 will be described. The driving mechanism 3 substantially opens and closes the tent frame 2 and includes a braking mechanism for fixedly maintaining the closed state, the open state, or the intermediate state thereof. First, a drive mechanism housing is appropriately provided below the drive frame 23 in the movable frame 21, and as an example, a drive unit 32 including a drive unit base, a motor, a speed reducer, a brake clutch unit, and the like is provided therein. It is equipped with.
[0017]
  Next, the tent body 4 supported by the tent frame 2 will be described. The tent body 4 is made of a synthetic resin sheet such as a vinyl sheet, a canvas or a composite sheet thereof, and the configuration thereof is A side portion 41 provided so as to hang downward from the top portion 40, and an appropriate portion of the strap 42 on the inner side thereof, the end frame 20 constituting the tent frame 2, the movable frame 21, etc. Fixed to. The tent hem 43 of the side portion 41 is set to be long so as to cover the outside of the base frame 1, and a weight-containing rope 44 having an appropriate weight is wrapped around the end portion of the tent hem 43 and folded. Joined by stitching, heat pressing or high frequency welding.
[0018]
  Further, the configuration of the tent skirt 43 has the following characteristics. In other words, the tent skirt 43 may be configured such that the skirt of the tent body 4 is folded and reinforced as it is, but only the portion of the tent skirt 43 is set to have a length shorter than the dimension of other portions. . Specifically, as shown in FIG. 8, the longitudinal dimension of the constituent material between the frame elements, that is, the constituent material of the side portion 41 (indicated by reference numeral 41a) is L.₀ Whereas +1 cm, the longitudinal dimension of the constituent material of the tent skirt 43 (indicated by reference numeral 43a) is L₀ In this state, the two are joined by heat welding or the like.
  Claims5The dimension in the longitudinal direction of the fixing member described in the above is numerically a total sum of pitches between the frame elements in the entire apparatus.
[0019]
  Needless to say, there is a mismatch in length between the two, so that the longitudinal dimension of the tent skirt 43 becomes insufficient in the joining as it is, but in reality, one pitch L between the frame elements such as the movable frame 21₀ Since the dimension of the constituent material 41a of the side portion 41 with a margin of about 1 cm per (generally several tens of centimeters) is taken, the constituent material 41a of the side portion 41 is shortened by, for example, 1 cm per span. They are formed into a shape that is uniformly fine in the longitudinal direction, as if they were wrinkled, and they are dimensionally matched and joined.
[0020]
  Incidentally, the reason why the tent body 4 is configured as described above is as follows. That is, since this type of tent body 4 is usually provided with a tent frame 2 as a supporting member, the tent body 4 is dimensioned to allow some drooping at the intermediate portion so as not to apply an excessive load to the tent frame 2. Normally, the length of each frame element such as the movable frame 21 is increased with a margin of about 1 cm per pitch.
  However, when the total size of the margin is about a few tens of centimeters as a whole device, if the size is brought down as it is, the margin will be wrinkled by a large wave at the end of the tent skirt 43. In order to avoid this, the above-described configuration is adopted.
[0021]
  Next, a description will be given of the shutter device 50 that opens and closes the end of the sliding opening / closing tent T. Incidentally, the shutter device 50 itself is not necessarily limited to be applied to the sliding type open / close tent, but can be applied to a general fixed tent warehouse or a general fixed building. Good. However, for example, in the case of a sliding open / close tent mounted on a vehicle, in many cases, a DC 24V or DC 12V power source is used as a vehicle power source, and considering that the shutter body 51 in the shutter device 50 is opened and closed by a DC motor. Therefore, it is preferable that appropriate measures are taken accordingly. This point will be described below.
[0022]
  In this shutter device 50, for example, a sheet-like shutter main body 51 is attached to a winding drum (not shown) so as to be freely wound, and these are housed in a shutter box 53 provided above the drive frame 23 as an example. ing. Further, when the shutter main body 51 is pulled out (when it is hung downward), a shutter guide 54 for guiding the shutter main body 51 is provided inside the pillar portions on both sides of the drive frame 23. The winding drum is driven by a driving device by switching the rotation direction between the winding direction and the feeding direction of the shutter main body 51. It should be noted that the shutter body 51 is provided with reinforcing bars using metal pipes or the like as appropriate at horizontal intervals, which are fitted to the shutter guide 54 at both ends so that smooth winding and unwinding can be performed. It is configured. Further, the shutter body 51 does not have to be in the form of a sheet, and may be a slat type.
[0023]
  Next, the tent skirt pressing mechanism 5 as a sealing mechanism of the present invention will be described. As shown in FIG. 4, the tent hem holding mechanism 5 fixes the shaft support pieces 55 at a plurality of positions with respect to the base frame 1 in the left-right longitudinal direction, and inserts the rotation shaft 56 into the shaft support pieces 55. Further, a pressing plate 57 is fixed to the rotating shaft 56, and the base frame 1 is provided with a clamping plate 59 at a portion to be a rotating end of the pressing plate 57. The drive frame 23 side of the base frame 1 includes a motor M for applying a rotational force to the rotary shaft 56 and a gear box 58 for increasing the rotational force from the motor M and further changing the rotational direction. An output shaft of the gear box 58 is connected to the rotating shaft 56. The motor M and the gear box 58 may be provided on the end frame 20 side.
[0024]
  When the pressing plate 57 is fixed to the rotating shaft 56, the twist of the rotating shaft 56 corresponding to the torque applied to the rotating shaft 56 is calculated as shown in FIG. Mark by twisting the twist as appropriate. Then, the pressing plate 57 is welded and fixed at an appropriate location along the marking, and a notch 57a is appropriately provided in the shaft support piece 55 so that the rotation of the rotating shaft 56 is not hindered. To do. At this time, the pressing plate 57 may be a single size, and a plurality of pressing plates 57 may be continuously attached. Depending on the shaft support structure of the shaft support piece 55, a single press without forming the notch portion 57a. The plate 57 may be attached.
  By the way, in the present embodiment, the SUS (stainless steel) φ22 rotating shaft 56 has a ruled line so that the 3.5 ° end frame 20 side is twisted in advance with a bead length of 20 mm at a pitch of 200 mm. The pressing plate 57 was spot welded. As a result, the pressing plate 57 was attached to the rotating shaft 56 of about 8 m with the end of the driving frame 23 side delayed by about 33 ° from the end of the end frame 20 side.
  The pressing plate 57 is preferably provided with a cushioning material 60 to which an elastic body (rubber, urethane, etc.) is applied.
[0025]
  The tent skirt holding mechanism 5 as a sealing mechanism of the present invention and the slide-type opening / closing tent T to which the tent skirt pressing mechanism 5 is applied have a specific structure as described above and operate as follows.
(1) Opened tent body
  For convenience of explanation, the opened state in which the tent body 4 does not cover the loading platform 11 will be described as the initial state. At this time, the movable intermediate frame 22 and the drive frame 23 of the movable frame 21 are contracted so as to contact each other, and the drive frame 23 is moved as far forward as possible to the loading platform 11.
  At this time, the tent skirt 43 hangs in an unfixed state so as to cover the outside of the base frame 1 as shown in FIG. 6A, while the pressing plate 57 in the tent skirt pressing mechanism 5 is closest to the gear box 58. Is located in the lower phase of the rotating shaft 56. The reason why the pressing plate 57 takes such a position is to avoid contact with the tent skirt 43 when the tent body 4 is expanded as described above.
[0026]
(2) Extension of the tent body
  When the tent body 4 is expanded in such a state, when the drive unit 32 is operated by a switching operation for appropriate power feeding and rotation is given to the drive wheel 23a, the drive wheel 23a moves on the rail 12. It rolls. As a result, the drive frame 23 moves to the rear of the loading platform 11, and the tent body 4 is successively extended. When the tent body 4 is extended in this manner, the top 40 will not hang down as shown in FIG.
[0027]
  When the drive frame 23 reaches the rear end of the loading platform 11, a part of the drive frame 23 presses a suitably provided limit switch, thereby turning off the drive power supply of the drive unit 32 and stopping its movement. When the drive in the drive unit 32 is stopped, the drive unit 32 is actively stopped by a brake unit or the like, and the forward / reverse rotation cannot normally be performed by the action of the speed reduction mechanism to which the worm gear mechanism incorporated in the drive unit 32 is applied. The rotation is stopped.
  Even in this state, the tent skirt 43 hangs in an unfixed state so as to cover the outside of the base frame 1, while the pressing plate 57 in the tent skirt pressing mechanism 5 is positioned in a lower phase of the rotating shaft 56.
[0028]
  Although the upper dimension of the tent body 4 is larger than the overall length of the loading platform 11 and the like, the tent skirt 43 coincides with the longitudinal dimension of the clamping plate 59 as a fixing member that is a total dimension of the pitch between the frame elements. Therefore, it does not jump out to the side of a large wavy shape and is maintained in an expanded state. For this reason, when the pressing plate 57 in the tent skirt pressing mechanism 5 is rotated, it can always be positioned within the range of the rotation trajectory to ensure a reliable closing. Incidentally, in order to ensure that the tent skirt 43 can be positioned within the range of the rotation trajectory of the pressing plate 57, it is not considered that the pressing plate 57 in the tent skirt pressing mechanism 5 is made larger. However, considering attachment to the side of the pressing plate 57 and twisting, it cannot be made unnecessarily large.
[0029]
(3) Pressing the tent hem
  Therefore, when the motor M in the tent skirt holding mechanism 5 is driven and a rotational force is applied to the rotary shaft 56 via the gear box 58, the pressing plate 57 rotates around the rotary shaft 56 as shown in FIG. Start moving.
  At this time, since the pressing plate 57 is attached by calculating the torsion of the rotating shaft 56 according to the torque applied to the rotating shaft 56, the portion closest to the gear box 58 is almost 180 ° as shown in FIG. A substantially uniform pressing force acts on the base frame 1 side over the entire longitudinal direction of the pressing plate 57 when it rotates. Thus, since the rotating shaft 56 is extremely long with respect to its shaft diameter, torque transmission loss due to elastic torsion of the rotating shaft 56 is preliminarily attached, and the pressing plate 57 is attached thereto. Further, the tent hem 43 is clamped between the cushioning material 60 and the clamping plate 59 on the base frame 1 side, and the tent skirt 43 is pressed in the closed state over the entire longitudinal direction.
  When a magnetic material is used as the buffer material 60, the tent hem 43 can be more stably closed because the magnetic material is autonomously attracted to the iron clamping plate 59.
[0030]
Embodiment 2
  Next claim4An embodiment of the invention specified by will be described.
  The tent skirt holding mechanism 5 in this embodiment is a mechanism that presses the tent skirt 43 with a magnetic force, and a flexible magnetic sheet 61 is attached to the tent skirt 43 in the whole longitudinal direction or dotted. It consists of
  Here, the magnetic sheet is a sheet formed by mixing synthetic rubber, elastomer, etc. with a magnetic material, metal powder, etc. The tent body 4 is flexible so long as it has excellent magnetism and mechanical strength. The more desirable it is. In addition, you may make it use the magnetic sheet which is a magnetized material which gave magnetic force to the magnetic sheet itself, and divides into the case where the magnetic sheet 61 does not have magnetic force and the case where it has below.
[0031]
(1) When the magnetic sheet has no magnetic force
  When the magnetic sheet 61 having no magnetic force is used, a magnet 62 is provided for the base frame 1. When an electromagnet is used as the magnet 62, an electromagnet as shown in FIG. The magnetic sheet 61 is attracted and released by the on / off operation, and the atmosphere between the storage space and the outside can be shut off during the adsorption.
  On the other hand, when a permanent magnet is used as the magnet 62, the magnetic sheet 61 is attracted and released by the approaching / separating operation of the magnet 62, as shown in FIG. Can be blocked.
[0032]
(2) When the magnetic sheet has magnetic force
  When the magnetic sheet 61 having a magnetic force is used, a metal cylinder 63 is provided as an example with respect to the base frame 1, and an appropriate suction blow-out device such as a small compressor is connected to the metal cylinder 63 so that air is sucked. The magnetic sheet 61 is attracted to the metal tube 63 by the above, and thereafter, the magnetic sheet 61 is attracted and held by the magnetic force of the magnetic sheet 61 to cut off the atmosphere between the storage space and the outside. This is intended to be separated from the metal cylinder 63.
[0033]
[Other embodiments]
  The present invention has the above-described embodiment as a representative embodiment, but the technical idea of the present invention includes the following modified embodiments.
  First, in the previous embodiment, the motor M and the gear box 58 were used to supply the rotational force to the rotating shaft 56. However, it may be performed manually (manually) by appropriately combining a handle and a ratchet mechanism. Also good. Moreover, you may make it give a rotational force to the both ends of the rotating shaft 56. FIG.
  In the previous embodiment, the sandwiching plate 59 is described as being provided on the base frame 1. However, if there is a portion of the base frame 1 that is opposite to the rotation end of the pressing plate 57, the sandwiching plate 59 is provided. There is no need to provide.
[0034]
  When the pressing plate 57 is attached to the rotating shaft 56, when the rotating shaft 56 has high rigidity and little twist, the pressing plate 57 is attached straight and attached to the pressing plate 57 as shown in FIG. The thickness of the buffer material 60 to be changed may be changed (tapered). Further, in order to efficiently obtain the rigidity of the rotating shaft 56, the diameter of the rotating shaft 56 may be changed to a tapered shape or a stepped shape. Further, in the previous embodiment, the tent hem holding mechanism 5 in the left-right longitudinal direction of the base frame 1 has been described. However, for example, the tent hem holding mechanism 5 in the front-rear width direction such as the skirt of the shutter body 51 may be used.
[0035]
【The invention's effect】
