Each end face is set to a predetermined mounting position in which the end face abuts or approaches the inner end face of each horizontal pipe 6c. At this time, the engaging member 81 engages the pin PN with the third through groove 832 and holds the pin PN at the retracted position Q. In this state, the horizontal beam 5 is sandwiched by the horizontal pipe 6c and cannot move in the longitudinal direction. Next, as shown in FIG. 12, the pins PN located in the third through-grooves 832 are
22 to release the temporary holding state, the engaging member 81 temporarily held at the retreat position Q by the temporary holding means 83 is elastically urged by the coil spring 821 to engage the engaging position from the end face of the horizontal pipe 6c. P, and is fitted into the inner periphery of the horizontal beam 5 with almost no gap as shown in FIG.
As a result, the horizontal beam 5 and the horizontal pipe 6c form a straight line, and the bracket 61 (6) is attached to each end of each horizontal beam 5.
2) are connected to each other, and the horizontal beam 5 is connected to the column 7 via each end of the horizontal beam 5 and the bracket 61 (62). Thereafter, the pin P moved to the outer end of the first through groove 822 together with the engagement member 81 biased to the engagement position P
By engaging N with the second through groove 831, the temporary holding means 83 is operated, and the engaging position P of the engaging member 81 is temporarily held. Next, by operating the screw portion BJ4 of the bon joint BJ, the interval between the two pressing members BJ2 and BJ3 is widened, and the bracket 61 (62) and the column 7 are completely fixed.

In addition to the above procedure, for example, first, engaging members 81 are engaged with the respective ends of the pair of horizontal beams 5 to connect the horizontal beams 5 to the brackets 61 (62). 61 (62) two supporting columns 7
It may be attached via a bone joint BJ. Next, when removing the horizontal beam 5 attached to the column 7 in this manner, first, the engagement state of the pin PN with the second through groove 831 is released in order to temporarily hold the engagement member 81 at the retracted position Q. I do. Subsequently, the pin PN is connected to the first through groove 82.
2, the pin PN is continuously engaged with the third through groove 832, and the engaging member 81 is temporarily held at the retreat position Q. Can be removed.

According to the connecting structure 4 according to the present embodiment, the column 7 and the horizontal beam 5 can be connected to each other or the connection can be released only by sliding the engaging member 81. Therefore, the conventional tightening operation using bolts can be omitted, and the assembling and disassembling operations of the temporary stand 10 can be greatly simplified. Further, by positioning the engaging member 81 at the retracted position Q, the engaging member 81 can be prevented from hindering the horizontal beam 5 from being set at the predetermined mounting position with respect to the support column 7. Connecting the horizontal beam 5 after connecting the brackets 61 and 62 to the upright supporting column 7,
After connecting the beam 62 and the horizontal beam 5, it is possible to connect the column 6 to the column 7. That is, since the support 7 and the horizontal beam 5 can be always connected irrespective of the assembly procedure, the assembly procedure is erroneously performed as in the conventional case where the support 7 and the horizontal beam 5 are connected by bolts. Does not occur again, and the burden on the operator can be reduced.

The horizontal beam 5 and the column 7 are connected via brackets 61 and 62, and the engaging members are supported on the brackets 61 and 62 which are relatively easy to work, and the urging means and the temporary holding means are provided. Since it is provided, the structure and manufacturing can be simplified, and it is possible to flexibly cope with a change in specifications and the like. Furthermore, in this embodiment, since the horizontal beam 5 has a pipe shape with a constant cross section, a special structure for engaging the engaging member 81 with the horizontal beam 5 may be provided. Not only is it unnecessary, but also it is possible to adjust the temporary stand 10 of any scale on site by simply cutting the horizontal beam 5.

Further, since the urging means 82 is provided with the coil spring 821 for elastically urging the engaging member 81 to the engaging position P, the engaging member 81 located at the retracted position Q is moved horizontally. When the engaging member 8 is engaged with the inner periphery of the
1 is located at the engagement position P, so that the connecting work between the column 7 and the horizontal beam 5 can be simplified. Also for the same reason,
Since the elastic biasing force to the engagement position P is always acting on the engagement member 81, the engagement member 81 once engaged with the horizontal beam 5
Is not easily released. Also horizontal beam 5
When the temporary holding means 83 is released in order to remove it, the connection between the column 7 and the horizontal beam 5 is difficult to be released by an unexpected force, and a situation in which the horizontal beam 5 falls on the demolition person's foot is avoided. be able to.

The temporary holding means 83 shares a pin PN which is a component of the urging means 82, and operates by engaging the pin PN with the second and third through grooves 832 provided in the horizontal pipe 6c. Therefore, the configuration can be made easily and inexpensively. Furthermore, since the engagement position P where the engagement member 81 is in the protruding state can be temporarily held by the function of the temporary holding means 83, the engagement position P of the engagement member 81 is not easily released,
The safety of the assembled temporary stand 10 is increased.
In addition, since the retreat position Q in which the engagement member 81 is in the immersed state can be temporarily held, it becomes easier to assemble and disassemble.

Further, since the horizontal pipe 6c, the horizontal beam 5 and the end pipe 6d constituting the brackets 61 and 62 have the same outer shape, when the chair 2 is slid on the horizontal beam 5, Since the slider 24 does not get caught at the joint between the horizontal beam 5 and the horizontal pipe 6c and between the horizontal pipe 6c and the end pipe 6d, the chair 2 can be easily slid on the horizontal beam 5.

The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, an engaging member provided on a bracket is provided on a horizontal beam, and the engaging member is engaged with the inner periphery of the horizontal pipe of the bracket to connect the column and the horizontal pipe. May be.

Further, the support and the horizontal beam are connected via a bracket.
Instead of connecting the beams, an engaging member provided directly on the column may be engaged with the inner periphery of the horizontal beam to connect the horizontal beam and the column. It is also possible to adopt a structure in which an engaging member provided directly on the column engages with the inner periphery of the column to connect the column and the horizontal pipe. In addition, the protruding and retracting direction of the engaging member is not limited to the horizontal direction, but is configured to protrude and retract in the vertical direction to engage with the inner periphery of the pipe-like column and connect the column and the horizontal beam. However, the present invention is not limited to the one provided with the bon joint.

The horizontal pipe is not limited to a pair. For example, only one horizontal pipe may be supported by a bracket and an engaging member may be provided on a support member. Instead, it may be a square pipe. The kind of the coil spring is not limited as long as it is an elastic body. In terms of the pin, a lever may be used as long as it performs the same operation as the pin. Of course, the temporary holding means is not limited to the above embodiment as long as it can temporarily hold the engagement position and the retreat position of the engagement member.

Further, regarding the bracket, its components and shapes are not limited. In addition, the configuration itself can be variously changed as long as it performs the same operation as the above embodiment. The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

By simply sliding the engagement member, the support members can be connected or disconnected from each other, so that the conventional bolting work can be omitted, and the assembly and disassembly work of the temporary stand can be omitted. Can be greatly simplified. Further, if the engaging member is set at the retracted position, the engaging member does not hinder the setting of the other supporting member at the predetermined mounting position with respect to the one supporting member, so that the engaging member can be used regardless of the assembly procedure. The support members can be connected without fail. In this regard, the burden on the operator for the assembly operation can be reduced.

The other support member is in the form of a pipe having a constant cross-sectional shape, and the engaging member has a cross-sectional shape substantially matching the inner peripheral cross-sectional shape of the other support member. In this case, if the other support member is fitted and engaged with the inner periphery of the other support member, there is no need to provide the other support member with a special structure for engaging the engagement member, The simplification in structure and assembly can be further promoted, for example, the length can be adjusted only by cutting the support member.

If one of the support members is a column that stands vertically and the other support member is a horizontal beam for supporting the seat, the effect of the connection structure of the present invention is particularly remarkable. be able to. If the biasing means includes an elastic body that elastically biases the engagement member to the engagement position,
The connection work between the support members can be simplified, and the engagement state between the support members is less likely to be released by an unexpected external force, so that safety can be improved.

The same effect can be obtained by providing temporary holding means for temporarily holding the engaging member at the engaging position and the retracted position, respectively. , The effect can be particularly remarkable. The support members are connected to each other via a bracket, and the engaging member is supported by the bracket so as to be able to protrude and retract between an engagement position protruding from the bracket and a retracted position retracted into the bracket. In this case, the supporting member is not subjected to any special processing, and the urging means or the like can be attached to the bracket which can be easily processed, so that the production and the structure can be simplified.

The bracket includes an upright portion which can be attached to an upper end portion of one of the support members, and a pair of horizontal pipes which are parallel to each other and are integrally provided at the upper end of the upright portion so as to have the same height. A horizontal beam can be attached to each horizontal pipe, and the length of the horizontal pipe is set between a retracted position in which the engaging member is immersed in the horizontal pipe and an engaging position protruding from an end surface of the horizontal pipe. If each horizontal pipe has the same outer diameter as the horizontal beam, not only can the seat be stably supported, but also the horizontal pipe and the horizontal beam can be provided. This makes it possible to avoid such a problem that the bracket interferes when the seat is mounted on the horizontal beam.

The biasing means includes a pin attached to the side surface of the engaging member in a region always immersed in the bracket, and the pin is provided on the outer wall of the bracket so as to extend along the predetermined direction. If it is configured to be able to move the engaging member between the engaging position and the retreat position by moving along the one through groove, an inexpensive and simple configuration can be achieved.

In this case, the provisional holding means includes a second through-groove and a third through-groove extending from each end of the first through-groove in a direction perpendicular to the predetermined direction, respectively.
By engaging the pin in the through-groove or the third through-groove to temporarily hold the engaging member at the engaging position and the retracted position, respectively, the components can be shared with the urging means and the manufacturing can be simplified. Can be achieved.
