    2. Description of the Related Art Conventionally, as a tire support pallet that supports vertically placed tires in two upper and lower stages, for example, those described in Patent Document 1 below are known.

Japanese Utility Model Publication No. 6-3877

  This has a base having a rectangular shape as a whole, a base end portion rotatably connected to one end and the other end of the base, and an upright position extending in the vertical direction, and a base center side A pair of horizontal frames that can swing between the sideways position that has fallen into the base, a lower support member that is attached to the base and can support the lower tire from below, and both horizontal frames A plurality of fixed tubular bodies, and projecting portions that can be fitted into the tubular bodies are formed at both ends, and an upper support member that can support the upper tire from below, and the both lateral frames stand up. When in the position, the protrusion of the upper support member is fitted into the tube so that the upper support member is attached to both lateral frames while maintaining a substantially horizontal posture.

    However, in such a conventional tire support pallet, when assembling the support pallet, both the lateral frames are swung from the lateral position to the upright position, and then both protrusions of the upper support member are connected to the pipe. On the other hand, it is necessary to insert both protrusions of the upper support member from the tube at the same time, and then swing both side frames from the standing position to the sideways position. However, there is a problem that it becomes complicated and difficult. In addition, since the upper support member removed from the tubular body is an independent member, there is a problem that the upper support member may be lost by being mixed in either during storage or transportation.

  An object of the present invention is to provide a tire support pallet capable of simplifying the assembly and storage operations of the support pallet while reliably preventing a situation where the upper support member is lost.

Such a purpose is a tire support pallet for supporting a vertically placed tire in two steps, a base having a rectangular planar shape as a whole, and base ends of one end and the other end of the base. A pair of horizontal frames that can swing between an upright position extending in the vertical direction and a sideways position that falls down to the center side of the base, and a lower stage. A lower support member capable of supporting the side tire from below, a first locking body provided on the side frame on one side, and a pivotally connected to the side frame on the other side, An upper stage support member that can be supported from below and an upper stage support member that is provided at one end of the upper stage support member and is locked to the first locking body when both lateral frames are positioned in the standing position. tire support path that includes a second engagement member for retaining in a substantially horizontal posture member The upper support member includes at least a pair of support rods parallel to each other, one end of all the support rods being fixed, a fixing member provided with the second locking body, and a lateral side on the other side. The other end of the frame is pivotally connected, and at least a pair of hollow supports each having a hollow hole into which a support rod is inserted. A first stopper that can be contacted is attached, and when the other lateral frame swings from the standing position to the sideways position, the fixing member is slid to one side on the lower support member and comes into contact with the first stopper. This can be achieved by restricting the movement of the fixing member and the support rod toward one side .

  In the present invention, the upper support member is pivotally connected to the other lateral frame, and the upper support member is engaged with a first locking body provided on one side lateral frame at one end of the upper support member. Since the two locking bodies are provided, when assembling the support pallet, it is only necessary to swing the both lateral frames from the horizontal position to the standing position and then lock the second locking body and the first locking body. On the other hand, when the support pallet is stored, after the lock between the second locking body and the first locking body is released, it is only necessary to swing both lateral frames from the standing position to the horizontal position. Easy assembly and storage of pallets. Moreover, since the upper support member is pivotally connected to the other side frame and is always integrated with the horizontal frame (even during storage, transport, etc.), the upper support member may be lost. It can be surely prevented.

In addition , when the other lateral frame swings to the sideways position, the hollow support body can move along the support rod to the center in the axial direction of the support rod. Even when stored, it can be stored in the base, saving space. Furthermore , since the first stopper restricts the movement of the support rod to one side, the hollow support can be moved to the axial center of the support rod simply by swinging the lateral frame on the other side toward the sideways position. Thereby, the storage operation of the support pallet can be facilitated while saving space.

Further, according to the structure as claimed in claim 2, since the second stopper restricts the movement to the other side of the support rod, simply swings towards the horizontal frame on the other side to the upright position, the hollow support The body moves to the other end of the support rod, and the upper support member can be easily extended to almost the required length, which facilitates the assembly operation of the support pallet. Furthermore, if comprised as described in Claim 3 , since the frictional resistance which arises between another hollow support body and a support rod is reduced, it is between the standing position and sideways position of the other side horizontal frame. Oscillation is smooth and the oscillating operation is facilitated .

  Reference numeral 36 denotes a horizontal support shaft extending in the left-right direction attached to the central portion in the longitudinal (height) direction of the other side lateral frame 27. The support shaft 36 has a hollow shaft as a pair of connecting bodies separated in the left-right direction. 37 is rotatably fitted. The other end of a pair of brackets 38 extending toward one side is fixed to each hollow shaft 37, but since the pair of hollow shafts 37 described above is provided, the brackets 38 are separated in the left-right direction and separated into two pairs. It will be provided.

  Reference numeral 40 denotes a plurality of support pipes (the same number as the brackets 38) in which through-holes 41 are formed, and these support pipes 40 are fixed to one end of the bracket 38, respectively. The upper support rods 32 are inserted through the hollow holes 41 of the support pipe 40, but the inner diameters of these hollow holes 41 are slightly larger than the outer diameters of the upper support rods 32. As a result, the upper support rod 32 and the support pipe 40 can relatively move in the axial direction while being in sliding contact with each other.

  The bracket 38 and the support pipe 40 described above constitute, as a whole, at least a pair of hollow supports 41 each having a hollow hole 41 into which the upper support rod 32 is inserted, here two pairs of hollow supports 42 arranged in parallel in the left-right direction. The pair of hollow supports 42 are connected to each other by a hollow shaft 37 at the other end, and the other end is rotatably connected to the other lateral frame 27 via the support shaft 36.

  In addition, in this invention, you may make it connect the hollow support body which makes a pair by a strip | belt-plate-shaped coupling body, or all the hollow support bodies mutually on one side from the other end. At this time, the support shaft is rotatably supported by the other side horizontal frame, while the other end of the hollow support is fixed to the support shaft, or the support shaft is fixed to the other side horizontal frame, while the hollow support is supported. The other end of the body may be pivotally connected to the support shaft. Furthermore, in this invention, you may make it support the other end part of a hollow support body in the other side horizontal frame so that rotation is possible directly via a support shaft.

  The above-described upper support rod 32, fixing member 35, and hollow support body 42 are pivotally connected to the other lateral frame 27 as a whole, and support the vertically placed vulcanized tire T located on the upper stage side from below. An upper support member 43 that can be configured is configured. In this upper support member 43, two pairs of upper support rods 32 and hollow support bodies 42 are arranged in parallel in the left-right direction, so that the support pallet 11 has two rows of vulcanized tires T on the lower side. Can be supported from. In the present invention, the upper support member may be composed of a pair or three or more pairs of support rods and a hollow support.

  If the upper support member 43 is composed of the upper support rod 32, the fixing member 35, and the hollow support 42 as described above, when the other lateral frame 27 swings to the sideways position L, the hollow support 42 is Since it can move along the upper support rod 32 to the center in the axial direction of the upper support rod 32, the entire upper support member 43, in particular, the upper support rod 32 can be moved into the base 20 even when the support pallet 11 is stored. It can be stored, and space can be saved. In the present invention, the upper support member may be folded in half at the longitudinal center, and the upper support member may be linearly extended and fixed during assembly, and folded and stored in the base during storage.

  Reference numeral 44 denotes a retaining member, such as a bolt, provided at the other end of each upper support rod 32. The retaining member 44 is pulled out from the support pipe 40 toward the one side. When trying to do so, the upper support rod 32 is prevented from coming off by coming into contact with the other end surface of the support pipe 40. Reference numeral 47 denotes a horizontal beam as a first horizontal locking body that is provided on the one side horizontal frame 22 and extends in the left-right direction. ) It is fixed at the center of the direction.

  Reference numeral 48 denotes one end of the upper support member 43, more specifically, a pair of locking claws as a second locking body provided on the fixing member 35. These locking claws 48 are respectively attached to the left and right ends of the support bracket 33. It is fixed. Each locking claw 48 penetrates the lower surface thereof in the left-right direction and has a recess 49 whose cross section is substantially the same as the cross-sectional shape of the horizontal beam 47. As a result, the cross-sectional shape of the locking claw 48 It will present a letter shape.

  The horizontal beams 47 are respectively inserted into the locking claws 48 (dents 49). Such insertion is performed when the horizontal frames 22 and 27 are located at the upright position K. The upper support rod 43 is centered on the base end (support shaft 36) while the upper support rod 32 is pulled out (moved to one side) from the hollow support 42 so that the distance between the upper support rod 43 and the locking claw 48 is increased. The upper support member 43 provided with the locking claw 48 is moved downward so as to approach the horizontal beam 47 from above. Thus, when the one side and the other side lateral frames 22 and 27 are located at the standing position K, the horizontal beam 47 is fitted into the locking claw 48 (the recess 49), and the locking claw 48 is engaged with the horizontal beam 47. Is locked, the upper support member 43 is substantially held in the horizontal posture M.

  On the other hand, when the one side and the other side lateral frames 22 and 27 are located at the standing position K, the upper support member 43 is slightly swung upward to release the locking claw 48 and the horizontal beam 47 from being locked. After that, the upper support rod 32 is pushed into the hollow support 42 (moved to the other side) so that the distance between the support pipe 40 and the locking claw 48 is slightly reduced, and then the fixing member 35 is moved to the lower support member. When the upper support member 43 is swung downward until it comes into contact with 15 (the lower support rod 14), the upper support member 43 is held in the inclined posture N.

  In this embodiment, as described above, the upper support member 43 is rotatably connected to the other lateral frame 27, and a horizontal beam 47 provided on the one side lateral frame 22 at one end of the upper support member 43. Since the latching pawl 48 that is latched to the support pallet 11 is assembled, both the lateral frames 22 and 27 are swung from the lateral position L to the standing position K, and then the latching pawl 48 and the horizontal beam 47 are assembled. On the other hand, when the support pallet 11 is stored, the locking pawl 48 and the horizontal beam 47 are unlocked, and then the horizontal frames 22 and 27 are moved from the standing position K to the sideways position L. All that is required is to swing, and as a result, the assembly and storage of the support pallet 11 is simplified. In addition, since the upper support member 43 is pivotally connected to the other lateral frame 27 and is always integrated with the other lateral frame 27 (during storage, transportation, etc.), the upper support member 43 is It is also possible to reliably prevent the loss.

  Here, in this embodiment, the second locking body is composed of a locking claw 48 as a recessed member having a recess 49, while the first locking body is a horizontal beam as a fitting member that is inserted into the recess 49. In the present invention, the first locking body is composed of a horizontal beam as a dent member having an opening opened upward, while the second locking body is fitted to the fixing member. You may make it comprise from the protrusion as a member and make a 1st, 2nd locking body latch by inserting an insertion member in the dent of the said dent member.

  That is, when the first locking body is constituted by either one of the dent member having a dent or the fitting member fitted into the dent, the second locking body is constituted by the other of the dent member or the fitting member. Good. In this way, the first and second locking bodies (horizontal beam 47, locking claw 48) can be easily locked or unlocked with a simple structure, and as a result, Further, the assembly and storage operations of the support pallet 11 are further simplified.

  2, 3, 5, 6, 7, and 9, reference numeral 51 denotes one end of the upper support member 43, specifically, a pair of handles fixed to the fixing member 35 apart in the left-right direction. If the holding operation is performed and the upper support member 43 is swung, the operation can be easily performed. Reference numeral 52 denotes a horizontal first stopper extending in the left-right direction. The first stopper 52 is disposed at a position close to the one-side horizontal frame 22, and the fixing member 35, specifically, the regulation claw 34 can come into contact therewith.

  Here, both ends of the first stopper 52 are fixed to two lower support rods 14 located on the center side among the four lower support rods 14, respectively. As a result, the first stopper 52 is It is attached to the base 20 on the side close to the one side lateral frame 22 via the support rod 14. Then, when the other side lateral frame 27 is swung from the standing position K toward the sideways position L when the upper stage support member 43 is in the inclined posture N, the fixing member 35 slides on the lower support rod 14 to one side. Thus, the restricting claw 34 comes into contact with the first stopper 52, thereby restricting movement of the fixing member 35 and the upper support rod 32 toward one side.

  When the other side lateral frame 27 is further swung toward the lateral position L in this state, the hollow support 42 moves to one side along the upper support rod 32 in a stationary state, and the axial direction of the upper support rod 32 It reaches the center, that is, the center in the longitudinal direction of the base 20. If the first stopper 52 is attached to the base 20 as described above, the hollow support 42 can be moved to the axial center of the upper support rod 32 simply by swinging the other side lateral frame 27 toward the lateral position L. Thus, the storage operation of the support pallet 11 can be facilitated while saving space.

  At this time, since the restricting claw 34 has an L-shaped cross section, when the fixing member 35 comes into contact with the first stopper 52, the lower part of the restricting claw 34 enters below the first stopper 52. Lifting of one end of the support rod 32 is prevented, and the movement of the upper support rod 32 to one side is reliably restricted. In the present invention, the first stopper may be directly attached to the base.

  56 is a second stopper extending in parallel with the lower support rod 14, and one end of the second stopper 56 is fixed to the first stopper 52. As a result, the second stopper 56 has the first stopper 52, The base 20 on the side close to the one-side horizontal frame 22 through the support rod 14, here, the base 20 is attached to the other side of the first stopper 52. The second stopper 56 has an abutting piece 56a having an inverted L shape at the other end, and a fixing member 35, specifically, a support bracket 33 can abut on the abutting piece 56a.

  When the fixing member 35 is positioned on one side of the contact piece 56a, if the other side lateral frame 27 is swung from the lateral position L toward the standing position K, the fixing member 35 is moved to the lower support rod. 14 slides on the other side and the support bracket 33 comes into contact with the second stopper 56 (contact piece 56a), thereby restricting movement of the fixing member 35 and the upper support rod 32 toward the other side. When the other side lateral frame 27 is further swung toward the standing position K in this state, the hollow support 42 moves to the other side along the upper support rod 32 in a stationary state, and the axial direction of the upper support rod 32 and the like. Reach the end.

  If the second stopper 56 is attached to the base 20 as described above, the second stopper 56 moves to the other side of the upper support rod 32 when the other lateral frame 27 swings toward the standing position K. Therefore, the hollow support 42 is moved to the other end of the upper support rod 32 by merely swinging the other side lateral frame 27 toward the standing position K, and the upper support member 43 is moved to almost the required length. The support pallet 11 can be easily extended and can be easily assembled.

  At this time, even if the support bracket 33 is about to come out upward, the contact piece 56a has an inverted L shape, so that the support bracket 33 is prevented from being pulled out upward due to being caught by the contact piece 56a. The above-described movement of the upper support rod 32 to the other side is reliably restricted. In the present invention, the first stopper described above may have the same configuration as the second stopper 56, but in this case, the beam having both ends connected to the lower support rod 14 is the first and second beams. 2 It becomes a member for attaching a stopper.

  6, 7, 10, and 11, the hollow support 42 is provided under the condition that one end of each of the upper support rods 32 described above is connected to the fixing member and the hollow support 42 is connected by the connection body. Although the central axes of the hollow holes 41 of the (support pipe 40) can all be parallel, in this embodiment, at least one of the hollow supports 42 (support pipe 40), In the embodiment, the central axis of the hollow hole 41 of the two hollow supports 42 (support pipes 40a) located on the outer side is used as another hollow support 42, here two hollow supports 42 (support pipes 40b) located on the center side. ) With respect to the central axis of the hollow hole 41 so as to go downward from the other side toward the one side.

  As a result, in the two hollow support bodies 42 (support pipes 40a) located outside, the edges at one end and the other end of the support pipe 40a are pressed against the outer periphery of the upper support rod 32 as shown in FIG. In the two hollow supports 42 (support pipes 40b) located on the other central side, the center axis of the support pipe 40b is substantially coaxial with the center axis of the upper support rod 32 as shown in FIG. The contact between the support pipe 40b and the upper support rod 32 is almost eliminated. As a result, the frictional resistance generated between the other hollow support 42 and the upper support rod 32 is reduced, and as a result, the overall frictional resistance between the hollow support 42 and the upper support rod 32 is reduced. Further, the swinging between the standing position K and the sideways position L of the other side lateral frame 27 becomes smooth, and the swinging operation becomes easy.

  Here, the intersection angle A between the central axis of the at least one hollow support 42 (support pipe 40a) and the central axis of the other hollow support 42 (support pipe 40b) is in the range of 2 to 4 degrees. preferable. The reason is that if the crossing angle A is less than 2 degrees, the frictional resistance with the upper support rod 32 in the other hollow support 42 (support pipe 40b) cannot be sufficiently reduced, while 4 degrees. This is because interference begins to occur between the upper support rod 32 and the support pipe 40, and it becomes difficult to insert the upper support rod 32 into the support pipe 40.

Next, the operation of the first embodiment will be described.
Now, it is assumed that the one side and the other side horizontal frames 22 and 27 are swung to the sideways position L as shown in FIG. 5 and the support pallet 11 in the stored state is stored in a predetermined storage area. At this time, since the hollow support 42 has moved along the upper support rod 32 to the axial center of the upper support rod 32, the upper support rod 32 is housed in the base 20, and the fixing member 35 The restricting claw 34 is in contact with the first stopper 52. At this time, in order to improve the storage density of the support pallets 11, the support pallets 11 are usually stacked in a plurality of stages. Next, a case where such a support pallet 11 is taken out from the storage area and assembled will be described.

  In this case, first, the operator swings the one side lateral frame 22 from the lateral position L toward the standing position K with the pin 17a as the pivot center. When swinging, the column 18 is inserted into the rectangular groove 24, and the upper half of the engagement piece 19a is inserted into the engagement groove 25, whereby the one-side horizontal frame 22 is strongly held in the standing position K. Next, the operator swings the other side lateral frame 27 from the lateral position L toward the standing position K with the pin 17b as the center of swinging. As a result of being pulled by the frame 27 and moving to the other side, the fixing member 35 (support bracket 33) is in sliding contact with the lower support rod 14, while the second stopper 56 is in contact as shown by the phantom line in FIG. It moves to the other side until it abuts on the piece 56a.

  When the fixing member 35 contacts the second stopper 56 in this way, the movement toward the other side of the fixing member 35 and the upper support rod 32 is restricted. In this state, the other side lateral frame 27 is further moved to the standing position K. When it is swung toward, the hollow support 42 moves to the other side along the stationary upper support rod 32, and the distance between the fixing member 35 and the support pipe 40 gradually increases. When the other lateral frame 27 swings to the standing position K, the support pipe 40 moves to the other axial end of the upper support rod 32, while the support 18 engages with the engagement groove 30 in the rectangular groove 29. The upper half of the piece 19b is inserted, whereby the other lateral frame 27 is strongly held in the standing position K. At this time, the upper support member 43 is in the inclined posture N, and the distance between the fixing member 35 and the support pipe 40 is slightly shorter than the distance when the vulcanized tire T is supported.

  Next, the operator grasps the handle 51 and pulls the upper support rod 32 slightly to one side, and shifts the fixing member 35 to a position where it does not interfere with the first and second stoppers 52 and 56. Thereafter, the upper support member 43 is swung upward from the inclined posture N to slightly beyond the horizontal posture M around the base end portion (support shaft 36), and the upper support rod 32 is pulled out from the hollow support 42 (one side). And the locking claw 48 is moved to a position directly above the horizontal beam 47. Next, the upper support member 43 is swung downward, and the horizontal beam 47 is fitted and locked to the locking claw 48.

  As a result, the upper support member 43 is substantially held in the horizontal posture M, and the assembly of the support pallet 11 is completed. Thereafter, the vertically placed vulcanized tire T is carried onto the lower support member 15 and the upper support member 43 as necessary, and the vulcanized tire T carried in by the lower and upper support members 15 and 43 is moved upward and downward. Support and store from below in steps. At this time, the support pallets 11 as described above are stacked in a plurality of stages, usually about three stages, to improve the support storage density of the vulcanized tire T.

  Next, when storing the support pallet 11, the upper support member 43 is slightly swung upward to remove the locking claw 48 from the horizontal beam 47, and after releasing the locking, the engagement with the support pipe 40 is performed. The upper support rod 32 is pushed into the hollow support 42 (moved to the other side) so that the distance to the pawl 48 is slightly reduced, and then the fixing member 35 is moved as shown by a solid line in FIG. The upper support member 43 is swung downward until it comes into contact with the lower support member 15 (lower support rod 14) between the first stopper 52 and the contact piece 56a of the second stopper 56. As a result, the upper support member 43 swings to the inclined posture N.

  Next, the other side horizontal frame 27 is slightly lifted upward to disengage the rectangular groove 29 and the engagement groove 30 from the support column 18 and the engagement piece 19b, and then the other side horizontal frame 27 is erected around the pin 17b. Swing from the position K toward the sideways position L. At the initial stage of the swinging of the other side lateral frame 27, the fixing member 35 is pushed by the other side lateral frame 27 and moves on the lower support rod 14 until the restricting claw 34 comes into contact with the first stopper 52. .

  When the fixing member 35 comes into contact with the first stopper 52, the movement toward the one side of the fixing member 35 and the upper support rod 32 is restricted. In this state, the other lateral frame 27 is further moved to the sideways position L. When it is swung toward, the hollow support 42 moves to one side along the stationary upper support rod 32, and the distance between the fixing member 35 and the support pipe 40 gradually decreases. When the other lateral frame 27 swings to the sideways position L, the support pipe 40 moves to the axial center of the upper support rod 32.

  Next, the one side horizontal frame 22 is slightly lifted upward to disengage the rectangular groove 24 and the engagement groove 25 from the support column 18 and the engagement piece 19a, and then the one side horizontal frame 22 is erected around the pin 17a. The support pallet 11 is stored by swinging from the position K to the sideways position L. The support pallet 11 thus stored is stored again in the storage area. When reassembling such a support pallet 11, the same operation as described above is performed, but at this time, the second stopper 56 (contact piece 56 a) is provided on the base 20 on the other side of the first stopper 52. Therefore, when the other side lateral frame 27 is swung toward the standing position K, the fixing member 35 that has been in contact with the first stopper 52 slides on the lower support rod 14 to the other side as it is, and the second stopper As a result, the operation becomes easy.

  The present invention can be applied to the industrial field in which a vertically placed tire is supported in two upper and lower stages.
