Description

  The present invention relates to a retaining device.

Conventional holding devices require a plurality of types of holding devices corresponding to the type and shape of the object to be packed, and most of these holding devices are waste materials after use, so the load on the environment is large. For example, in Patent No. 3008971, the present inventors can hold an arbitrarily-shaped object to be held, and can be folded into a small space before and after use to save space, and can be used repeatedly. There has already been proposed a holding device that does not occur and is easy to hold. In this retaining device, a material to be secured on a pallet is covered with a cover having flexibility and airtightness, and the bottom of the cover is hermetically fitted into an annular groove continuously formed on the side surface of the pallet, so that the air inside the cover Is deaerated with a vacuum pump or the like, so that the cover is brought into close contact with the object to be retained at atmospheric pressure, and the object to be retained is retained by the cover and the pallet.
Patent No. 3008971

  However, the retaining device using the atmospheric pressure is expensive because the pallet surface surrounded by the cover needs to be completely airtight. Moreover, since it is necessary to attach the skirt part of a cover to a pallet in the state which ensured airtightness, the maintenance operation | work was complicated.

The retaining device according to the present invention includes a rectangular pallet provided with a to-be-retained body placing portion for placing a to-be-retained body at a central portion, and four erected around the to-be-retained body placing portion of the pallet. The support post, the body of the to-be-supported body placed on the to-be-supported body placing portion, the air-tight bag-like retaining body having an air inlet, and a plurality of circumferential positions of the retaining body. In the state where the throttle part provided in the vertical direction, the retainer is mounted on the object to be held, four connection parts connected to the four throttle parts adjacent to the pillar, and the upper part of the pillar are hung between the pillars. and a ceiling member mounted to be passed, substantially in the center of the coercive Teikarada mounting portion of the pallet, four waist portion of Hihoteikarada of mounting to fit within the rectangle strut as vertices the coercive Teikarada fitted, the connecting portion, and consolidated in strut adjacent thereto, coercive Teikarada from the air inlet Put gas, corners with attached connecting portion is inflated coercive Teikarada to move radially inwardly with is brought into close contact with the holding Teikarada, is to retain the target coercive Teikarada the struts tensioned on the connecting portion .

  Since this retaining device does not need to attach the pallet and the retaining member in an airtight manner, the structure of the pallet can be simplified and manufactured at a low cost. In addition, the holding work of the to-be-fixed body is carried out by attaching the holding body around the body of the to-be-held body placed on the to-be-held body mounting portion of the pallet, connecting the holding body and the support column at the connecting portion, and introducing air Since it is good to put gas into the retaining body from the mouth, workability is also good.

  A plurality of support pillars 3 are erected around the to-be-held object placing portion 7 of the pallet 2. In this embodiment, a square column is adopted as the column 3 and the column insertion hole 2 c formed in the pallet 2 is formed in the square hole. And the support | pillar 3 is inserted and installed in the support | pillar insertion hole 2c formed in the four corners of the upper surface 2a of the pallet 2, respectively. Moreover, in this embodiment, since the ceiling member 4 is attached to the upper part of the support | pillar 3, it is good to employ | adopt the support | pillar 3 of suitable length according to the height of the copying machine 6 to hold | maintain. Moreover, in order to give versatility, the support | pillar 3 may be provided with the structure which can adjust length.

  The ceiling member 4 is a member that is attached to the upper portion of the support column 3 so as to be spanned between the support columns 3. In this embodiment, the ceiling member 4 is formed of a rectangular top plate as shown in FIG. The ceiling member 4 is formed to be slightly larger than the outer shape of the pallet 2, and when the flange 4a is extended downward from the side surface and the ceiling member 4 is overlaid on the pallet 2 as shown in FIG. In addition, the side surface 2b of the pallet 2 is covered. Further, as shown in FIGS. 1 and 5, locking pieces 4 b protruding upward are provided at the four corners of the upper surface of the ceiling member 4. As shown in FIG. 2, a column insertion hole 4 c for inserting the upper end of each column 3 is provided on the lower surface of the ceiling member 4.

As described above, the column 3 is installed at the upper end portion with the ceiling member 4 so that the interval between the columns 3 is maintained and stably stands. In this embodiment, the support column 3 is fitted into the support column insertion hole 2c of the pallet 2 and the support column insertion hole 4c of the ceiling member 4, respectively. I am letting.

  Further, as shown in FIG. 1, grooves 4 d and 4 e are formed on the upper surface of the ceiling member 4 to accommodate the support columns 3 lying sideways. In this embodiment, the grooves 4 d and 4 e are formed in a cross so that two columns can be accommodated on the diagonal line of the ceiling member 4. Further, as shown in FIG. 6, the groove 4e formed on one diagonal line is made deeper than the groove 4d formed on the other diagonal line, and the column 3 arranged in a cross intersects the grooves 4d and 4e. I try not to interfere.

  The retaining member 5 is formed in a bag shape and is mounted around the body of the copying machine 6 placed on the restraint member placing portion 7. In this embodiment, as shown in FIG. 1, the retainer 5 is attached to the periphery of the copier 6 and the body periphery retaining part 12. It has the connection part 13 respectively connected with the support | pillar 3 provided.

  The waist circumference retaining portion 12 has an airtightness and flexibility, and an inner peripheral fabric and an outer peripheral fabric, which are made of a sheet material having little stretchability, are overlapped, and upper and lower hem portions 12a and circumferential edges. The portion 12b is thermally welded by a high frequency welding method to form an air chamber therein, and the end portion 12b in the circumferential direction is formed into a rectangular tube shape by joining with a sewing machine or the like. The sheet material of the trunk periphery retaining portion 12 can be formed of a stretch cloth made of polyurethane. In this embodiment, the throttle portions 14 are further provided in the longitudinal direction at a plurality of locations in the circumferential direction of the waist circumference retaining portion 12.

  The narrowed portion 14 is formed by thermally welding the inner peripheral side fabric and the outer peripheral side fabric of the waist circumference retaining portion 12 at the intermediate portion in the vertical direction. In this embodiment, when mounted around the body portion of the copying machine 6, the middle portion of each side and the two portions of the body periphery holding portion 12 are divided so that each side of the body periphery holding portion 12 is divided into approximately three equal parts. The corner portions are thermally welded to form the narrowed portion 14. In the formation of the throttle part 14, the upper part and the lower part of the waist circumference retaining part 12 are not thermally welded to each other, and the inside is communicated. The waist circumference retaining portion 12 is provided with an air introduction port 15 for introducing air by connecting a compressor. However, since the waist circumference retaining portion 12 communicates in the circumferential direction, the air introduction port 15 is preferably provided at one location.

  The connecting portion 13 is attached at a position corresponding to a corner portion of the trunk circumference retaining portion 12 when the trunk circumference retaining portion 12 is mounted around the trunk portion of the copy machine 6. The connecting portion 13 is firmly attached to the throttle portion 14 where the waist circumference retaining portion 12 is thermally welded up and down by sewing or the like. In this embodiment, the connecting portion 13 forms a sheet material in a loop shape, and stitches the loop material 16 to the waist circumference retaining portion 12 with both ends thereof aligned.

  Next, the operation of holding the copying machine 6 on the holding device 1 will be described.

  When holding the copying machine 6, the holding device 1 first holds the to-be-held body mounting portion at the center of the pallet 2 so that the to-be-held body 6 can be disposed on the pallet 2 at the substantially center of the pallet 2. A rail 9 is laid on 7. Then, the caster 6 a of the copying machine 6 is placed on the rail 9, and the copying machine 6 is placed on the to-be-fixed body placing part 7 of the pallet 2. At this time, the copier 6 is installed so that the corners of the copier 6 are substantially oriented in the diagonal direction of the pallet 2.

  Next, the trunk circumference retaining portion 12 of the retaining body 5 is mounted around the trunk portion of the copying machine 6 placed on the pallet 2. Then, as shown in FIG. 1, the lower end 3a of the column 3 is inserted into the column insertion hole 2c of the pallet 2 while passing the column 3 through the loop 16 of the connecting portion 13 of the retaining body 5, as shown in FIG. The prop 3 is erected at the four corners of the pallet 2. Then, as shown in FIG. 1, the column insertion hole 4 c of the ceiling member 4 is attached to the upper end portion 3 b of the column 3, and the ceiling member 4 is attached to the upper end of the column 3.

  Thus, after assembling the pallet 2, the copy machine 6, the column 3, the retaining member 5, and the ceiling member 4, a compressor is attached to the air inlet 15 of the retaining member 5 to supply air. As a result, the waist circumference retaining portion 12 of the retaining body 5 is inflated and brought into close contact with the copying machine 6. At this time, the copy machine 6 receives air pressure introduced into the waist circumference holding part 12 of the holding body 5 and is held from the periphery. Moreover, when the trunk periphery holding | maintenance part 12 of the holding body 5 swells, as shown in FIG. 3, the outer periphery shape of the trunk periphery holding | maintenance part 12 tends to deform | transform into the most reasonable shape. As a result, the corner portion where the connecting portion 13 is attached to the waist circumference retaining portion 12 moves toward the inner diameter side. As a result, a required tension is applied to the connecting portion 13 connecting the support column 3 and the waist circumference holding portion 12 of the holding body 5 as shown by the arrows in FIG.

  Thus, when the required tension is applied to the connecting portion 13, the copier 6 is pulled evenly from the surroundings. Moreover, the support | pillar 3 applies the force to the internal diameter direction of the pallet 2 to the site | part which connected the connection part 13, and in order to support it, the support | pillar insertion hole 2c of the pallet 2 and the support | pillar insertion hole 4c of the ceiling member 4 are respectively outside. The force which supports a support | pillar acts in radial direction. Thereby, each coupling | bonding of the pallet 2, the support | pillar 3, and the ceiling member 4 also becomes strong. Further, the copying machine 6 is fastened to the waist circumference holding part 12 of the holding body 5 and tension is applied to the connecting part 13, so that the copying machine 6 is held so as not to move in the vertical direction. For this reason, for example, even when a vertical swing is applied when transported by a truck or the like, a problem such as the copying machine 6 jumping on the pallet 2 does not occur.

  Next, when releasing the holding of the copying machine 6, the check valve of the air inlet 15 may be opened to release the gas in the holder 5 from the air inlet 15 to the atmosphere. As a result, the state in which the waist circumference retaining portion 12 is in close contact with the copy machine 6 is released, and the tension applied to the connecting portion 13 is also eliminated. Thereby, it is good to remove from the pallet 2 in order of the ceiling member 4 and the support | pillar 3, and to remove the retaining body 5 from the copy machine 6.

  Next, an operation for folding and storing the retaining device 1 will be described.

  First, as shown in FIGS. 5 and 6, the rails 9 laid on the pallet 2 are moved to both sides of the pallet 2, a space is secured in the center of the pallet 2, and the retainer 5 is folded and stored therein. . Then, the ceiling member 4 is overlaid on the pallet 2, and the rubber band 11 provided at the corner of the side surface of the pallet 2 is engaged with the locking piece 4 b of the ceiling member 4. And the support | pillar 3 is accommodated in the groove | channels 4d and 4e of the ceiling member 4. FIG. As a result, the set of the holding device 1 (pallet 2, support column 3, ceiling member 4, holding body 5, to-be-fixed body placing portion 7) can be gathered together in a compact manner, and can be easily transported and reused. In this case, since each member is gathered together, reuse becomes easy.

  As described above, since it is not necessary to attach the pallet 2 and the retaining body 5 in an airtight manner, the structure of the pallet 2 can be simplified and can be manufactured at low cost. Further, the holding operation of the copying machine 6 is performed by attaching a holding body around the body of the copying machine 6 placed on the to-be-held body placing section 7 of the pallet 2, and connecting the holding body 5 and the column 3 by the connecting section 13. In addition, workability is good because it is better to put gas into the retainer 5 from the air inlet 15.

    The retaining device according to one embodiment of the present invention has been described above. However, the retaining device according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. Can be added.

  Although the to-be-fixed body 6 was illustrated with the copying machine with a caster, it is not limited to a copying machine. The article to be held 6 may be a cube-shaped product such as a refrigerator, a washing machine, or an outdoor unit of an air conditioner. Moreover, the external shape of a to-be-held body is not limited to a cube shape, A cylindrical shape, a column shape, and polygonal shape may be sufficient. In order to retain a copier with casters, rails were laid for convenience so as not to damage the top surface of the pallet. However, such rails are not always necessary and are used as appropriate according to the product to be retained. be able to.

  The retaining body 5 has been illustrated with the connecting portion 13 integrally attached to the corner of the waist circumference retaining portion 12. For example, the retaining body 5 is the waist circumference retaining portion 12, and the connecting portion 13 is separated from the retaining body 5. May be engaged. Moreover, although the connection part 13 was illustrated with the loop, since the tension | tensile_strength is generated in the connection part 13 when the retainer 5 is inflated and the engagement of the connection part 13 and the support | pillar 3 is maintained, It is not limited to loops. For example, the connecting portion 13 may be wound around the support post 3 and fixed with a magic fastener to make the connecting portion 13 difficult to be detached from the support post 3.

  Moreover, although the thermal welding of the trunk periphery holding | maintenance part 12 and the connection part 13 of the holding body 5 was illustrated by the high frequency welding method, it is not limited to the high frequency welding method. For example, heat welding can be performed using a hot plate welding method, an ultrasonic welding method, or the like.

  Although the ceiling member 4 is exemplified by the top plate, it is not limited to the top plate, as long as the upper end portion of the column 3 is fixed and the length between the columns 3 can be kept constant. For example, a beam or a crosspiece engaged with the column 3 may be used. When the column 3 is fixed with the beam or the crosspiece, not only the adjacent column but also a diagonal column may be fixed. Moreover, when the support | pillar 3 can be firmly fixed to a pallet, a ceiling member may be omitted.

  Although the support | pillar 3 was illustrated with the prism, it is not limited to a prism. For example, it can also be a cylinder. When this column is a cylinder, the column insertion holes 2c and 4c can also be formed in a circular hole. Moreover, although the support | pillar 3 was inserted in the support | pillar insertion hole 2c of the pallet 2 and it stood and illustrated, you may make it engage with an engaging member separately.

  Moreover, although the compressor was illustrated in order to put air into the trunk periphery holding body 12 of the retainer body 5, since it should just be able to put air into the trunk periphery holding part 12, it is also possible to use a stepping type air pump, for example. it can.

  Moreover, although the pallet 2 and the ceiling member 4 were engaged with the rubber band 11, since the retaining device 1 should just be folded and packed together compactly, it is not limited to the rubber band 11, but with engagement members, such as a string. There may be.
