Description

  The present invention is a construction unit used for constructing a structure necessary for photographing in order to support various photographing equipments in the field of filming, photography, etc. The present invention relates to a construction unit used for a connected structure such as a scaffold in the field.

In general, in the field of movie shooting, photo shooting, etc., it is necessary to quickly change the arrangement and structure of shooting equipment such as lighting equipment, microphones, and reflex plates according to the scene. It is also necessary to quickly assemble or move a simple structure necessary for a shooting set or the like while freely changing the size and shape.
Conventionally, structures that support such photographic equipment are mainly designed for each equipment, and the degree of freedom of use has been small.

In addition, a frame structure for installing sound equipment at a concert venue, a scaffolding at a construction site, and the like use a connected structure that is assembled before the start of an event or work and disassembled and stored at the end.
In order to construct such a connected structure, a construction unit composed of a pillar member, a beam member, and a connecting member for detachably connecting these members is required. An example of this is proposed in Patent Document 1. ing.

JP 2008-185173 A

  By the way, the following problems to be improved remain in the above-described conventional technology.

  In the conventional connecting structure building unit described above, a connecting portion protrudes from the side of the pipe in order to connect the pipe in the horizontal direction, and the side of the pipe or sub-joint is fixed to fix the pipe. Screw holes are integrally formed so as to protrude from the side surface.

  That is, there are many protrusions on each member of these connecting portions, and the above-mentioned many protrusions become an obstacle when disassembling and storing the building unit after using the connecting structure, and this saves storage space. There is a risk of becoming larger.

  In addition, it is assumed that these protrusions cause entanglement between the constituent members of the construction unit during storage, and handling becomes complicated.

  In addition, when fixing the pipe in each of the two directions, three directions, and four directions in the horizontal plane, it is necessary to form as many connecting portions as the number of directions to be connected to the side surface of the pipe. The above-mentioned problems are promoted.

  Furthermore, as described above, when fixing pipes in two directions, three directions, and four directions in a horizontal plane, it is necessary to prepare a pipe having a connecting portion corresponding to each connecting direction, and increase the number of parts. Is concerned.

  On the other hand, in order to speed up the assembly work, it is necessary to store these parts for each type and make it easy to take out the target parts. There is a risk that parts management becomes complicated.

  The present invention has been made in view of the above-described conventional problems, and it is possible to reduce the storage space and reduce the storage space of the constituent members of the construction unit for constructing the connected structure by minimizing the protrusions as much as possible. Another object of the present invention is to provide a connected structure construction unit that can suppress an increase in the types of components as a configuration that can handle a plurality of types of connection forms.

  The construction unit for a connected structure according to claim 1 of the present invention is a construction unit that is connected to each other to construct a connected structure, and is a cylindrical shape that constitutes a beam or a column of the connected structure. And a plurality of connecting means for connecting the frame constituents, and the connecting means is detachably mounted on a base made of a polyhedron and an arbitrary surface of the base. The engagement of the connecting rod to which the end portion of the frame structure is fitted, and the overlapping portion of the connection rod and the frame structure fitted to the connection rod to restrain the relative movement thereof. It is characterized by comprising a stop member.

  With such a configuration, a connecting rod is attached to a predetermined surface of the base constituting the connecting means, and one end portion of the skeleton structure is fitted on the connecting rod, and these overlapping portions are attached to these overlapping portions. By engaging the locking member, the base body and the framework structure are connected.

  By sequentially connecting a plurality of the frame structural bodies in the horizontal direction or the vertical direction via the base body and the connecting rod, a frame of the target structure can be constructed.

  Here, since the base body is a polyhedron, by selecting the surface and mounting the connecting rod, the connection form of the framework structure connected to the connecting rod, for example, L-shaped in a horizontal plane, T-shaped, cross-shaped, etc., and can be connected in the horizontal and vertical directions.

  Further, when the base is a hexahedron such as a cube or a rectangular parallelepiped, for example, the frame structure can be connected in any of six directions orthogonal to each other.

  In such a connection structure, the frame structure and the base are connected via a connection rod attached to the base, and the connection rod is connected to the frame structure (connection). Since it is selectively attached to the corresponding surface of the base body in accordance with the direction), it can be handled by a single base body regardless of the connection form of the frame structure.

  And since the attachment structure of the said base | substrate and a connection rod and the connection structure of this connection rod and a frame structure can be unified easily, there are few kinds with respect to the various connection forms of the said frame structure. It is possible to cope with the parts.

  In addition, since the connecting rod that connects the base body and the framework structure is configured to be detachable from the base body, the base rod, the connecting rod, and the frame structure body are formed by separating them.

  By adopting such a configuration, the framework structure is fitted onto the connecting rod and the respective through holes are overlapped, and then the locking member is fitted into the overlapped through hole. Both can be connected by work.

After the connection, the frame structure and the connecting rod are prevented from coming off by a shearing force acting on the locking member.
Accordingly, a strong connection can be realized.

  According to a fourth aspect of the present invention, there is provided the connecting structure building unit, wherein the locking member according to any one of the first to third aspects protrudes from the inside of the connecting rod to the outside. And biased toward the protruding position by a biasing member provided in the connecting rod.

A framework component is fitted, and the locking member is brought into elastic contact with the inner wall of the framework component.

When the fitting of the frame structure is continued, the through hole formed in the frame structure and the locking member are overlapped, and at the same time, the locking member is urged by the urging member. It is made to fit in the through hole.
As a result, the locking member is fitted into the through holes of the frame structure and the connecting rod to connect the two.

  As described above, the connecting operation of the frame structure can be performed by a simple operation of covering the frame structure on the connecting rod.

  According to a fifth aspect of the present invention, there is provided a connecting unit for a connected structure, wherein the locking member according to any one of the first to third aspects is a fitting portion between the frame structure and the connecting rod. It is characterized by being comprised by the latching pin attached by penetrating in radial direction, and the retaining member attached to this latching pin.

  With such a configuration, the framework structure and the connecting rod are held in a connected state by a shearing force acting on a locking pin that is attached through each of the framework structure and the connecting rod. A contact part with a structure and a connection rod can be enlarged, Therefore, these connection strengths can be improved significantly.

According to the present invention, the components of the connected structure building unit are made as common as possible to reduce the number of parts as much as possible, thereby simplifying the storage and retrieval of the connected structure. Construction can be speeded up.
In addition, the number of protrusions formed on each component can be reduced as much as possible to reduce the space formed between them during storage, thereby reducing the storage space and entanglement between the components. Can be suppressed to facilitate handling.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.
In FIG. 1, a symbol B indicates a connected structure constructed according to the present embodiment, and a symbol U indicates a construction unit according to the present embodiment.

  The construction unit U according to the present embodiment includes a plurality of cylindrical frame structures 1 constituting the beams and columns of the connection structure B, and a plurality of connection means J for connecting these frame structures 1 to each other. And the connecting means J is a polyhedral base 2 and a connecting rod 3 that is detachably attached to an arbitrary surface of the base 2 and on which an end of the framework structure 1 is fitted, The connecting rod 3 and the locking member 4 that engages with the overlapping portion of the frame structure 1 fitted on the connecting rod 3 and restrains the relative movement thereof.

It is made to be able to.

  In the present embodiment, the base body 2 is a cube-shaped hexahedron. As shown in FIG. 2, the hexagon socket head cap screw 5 for connecting the connecting rod 3 to the center of each surface is provided on each surface. Screw holes 2a are formed, and positioning holes 2b are formed at four corners of each surface at the same distance from the center of the screw holes 2a.

  The through-holes 1a formed in the framework structure 1 are formed at a total of 8 locations on each surface of both end portions of the framework structure 1, and each of the through holes 1a is located at a certain position from the end of the framework structure 1. Is formed.

  The through-holes 3a formed in the connecting rod 3 are formed at a total of eight positions on each surface near one end of the connecting rod 3, and are formed at fixed positions from the end of the connecting rod 3, respectively. Has been.

  As shown in FIG. 2, one end of the connecting rod 3 is bottomed, and a bolt insertion hole 3b through which the hexagon socket head bolt 5 is inserted is formed at the center thereof.

  Furthermore, a pair of positioning pins 6 extending in the length direction of the connecting rod 3 are provided on one end face of the connecting rod 3 at the corners of the connecting rod 3 on both sides of the bolt insertion hole 3b. ing.

  These positioning pins 6 have an outer diameter slightly smaller than the inner diameter of the positioning hole 2b formed in the base body 2 and can be fitted into the positioning holes 2b. The distance between the pair of positioning holes 2b located on the diagonal line is the same as the distance.

  The locking member 4 is formed to have an outer diameter slightly smaller than the inner diameter of the through hole 1a of the frame structure 1 and the through hole 3a of the connecting rod 3, and the thickness of the frame structure 1 and the A cylindrical portion 4a that is higher than the total thickness of the connecting rod 3 and a substantially conical guide portion 4b that extends forward from the cylindrical portion 4a in the axial direction are formed.

  In the present embodiment, a pair of the locking members 4 are provided. As shown in FIG. 2, on the outer side of both end portions of the urging member 7 formed in a substantially U shape, on the cylindrical portion 4a side. It is attached integrally.

  The urging member 7 is made of spring steel or the like, and a notch 7a is formed in a U-shaped curved portion.

  Further, the biasing member 7 is formed so that the distance between both ends thereof is larger than the distance between the opposing inner wall surfaces of the connecting rod 3 in a free state where no external force is applied.

  When the engaging member 4 is inserted into the connecting rod 3 with the urging members 7 narrowed at both ends, the engaging member 4 is fitted to the through-hole 3a of the connecting rod 3. The urging force of the urging member 7 is projected to the outside from the through hole 3a and is held at the protruding position.

  A procedure for constructing the connected structure B using the construction unit U of the present embodiment configured as described above will be described.

First, the hexagon socket head bolt 5 is inserted into the connecting rod 3 constituting the connecting means J, the tip of the bolt is inserted into the bolt insertion hole 3b at one end of the connecting rod 3, and the rear side The locking member 4 is inserted together with the biasing member 7, and the locking member 4 is fitted in the through hole 3 a of the connecting rod 3.
In this state, the locking member 4 is held in a state of projecting a predetermined length from the pair of parallel walls of the connecting rod 3 to the outside by the elasticity of the biasing member 7 (see FIG. 4).

  Thus, one end of the connecting rod 3 is opposed to one surface of the base 2 and a pair of positioning pins 6 projecting from the one end are fitted into the pair of positioning holes 2 b of the base 2. The one end portion of the connecting rod 3 is brought into contact with one surface of the base body 2 while being made to move.

Then, the hexagon socket head bolt 5 protruding from one end of the connecting rod 3 is screwed into a screw hole 2 a formed in the base body 2, thereby connecting the connecting rod 3 to the base body 2. Fix it.
In order to rotate the hexagon socket head bolt 5, a hexagon wrench or the like is inserted into the connecting rod 3 through the notch 7 a formed in the biasing member 7 and the head of the hexagon socket head bolt 5 is inserted. This is done by fitting in a hexagonal hole and rotating.

  The base 2 and the connecting rod 3 thus connected constitute a connecting means J. The base 2 and the connecting rod 3 are firmly fixed by the hexagon socket bolt 5 described above. At the same time, since the relative rotation is prevented by the fitting between the positioning pin 6 projecting from the connecting rod 3 and the base 1, the connecting means J having a rigid structure is obtained.

  And as an example, if it shows about the example used for the corner | angular part of the connection-type structure B which should construct | assemble this connection means J, as shown in FIG. Then, the connecting means J used for the corner as shown in FIG. 5 is obtained by fixing to three surfaces, one surface orthogonal to these surfaces.

  Next, after fitting one end of the framework structure 1 to each of the three connecting rods 3 attached to the one base body 2, the locking member 4 is pushed into the connecting rod 3. Then, the fitting of the framework structure 1 is advanced.

When the fitting of the frame structure 1 is advanced until the through hole 1a and the through hole 3a of the connecting rod 3 match, the locking member 4 is pushed outward by the biasing force of the biasing member 7. And fitted into the through hole 1a of the frame structure 1.
As a result, the framework structure 1 and the connecting means J are connected.

  And the corner | angular part of the said connection type structure B is comprised as shown in FIG. 6 by attaching | attaching three of the said frame structure 1 with respect to each of the said three connection rods 3. As shown in FIG.

  By performing the above operation sequentially at each end of the framework structure 1 while adjusting the connection position of the base 2 and the connection rod 3 in accordance with the installation direction of the framework structure 1, the framework configuration is performed. The body 1 can be connected in a linear shape, an L shape, a T shape, a cross shape, or the like to construct a connected structure B as shown in FIG.

  On the other hand, in order to disassemble the constructed connecting structure B, the connection between the framework component 1 and the connecting rod 3 and the connection between the connecting rod 3 and the base body 2 are performed in the reverse order of the procedure described above. You can cancel it.

The disassembled framework structure 1, connecting rod 3, and base body 2 are substantially hexahedrons, and the protrusions are minimized, so that they can be neatly aligned during storage.
As a result, the storage space is effectively used, and efficient storage is possible.

  In addition, since the protrusions are suppressed to a minimum, there is little entanglement between the constituent members, and the storing and taking out operations are simple.

  The various shapes, dimensions, combinations, and the like of the constituent members shown in the above embodiment are merely examples, and various changes can be made based on the shape, design requirements, and the like of the coupled structure B to be applied.

  For example, instead of the locking member 4 attached to the connecting rod 3 as described above, as shown in FIG. 7, the fitting portion between the frame structure 1 and the connecting rod 3 is penetrated in the radial direction. It is also possible to configure by a locking pin 8 attached in this manner and a retaining pin 9 attached to the locking pin 8.

  By setting it as such a structure, the support surface which supports the force of the pulling direction of the said frame structure 1 and the said connecting rod 3 can be expanded, and the intensity | strength can be raised.

Further, in addition to the single use of the base body 2, as shown in FIG. 8, two base bodies 2 are connected using full screws 10 to form a rectangular parallelepiped base body as shown in FIG. It is also possible to connect the connecting rod 3 (not shown) and the skeleton structure 1 to 2.
And the connection structure of the said base | substrate 2 can consider the form which connects two or more so that it may orthogonally planarly as shown in FIG.

In this way, by connecting a plurality of the base bodies 2, it is possible to assemble the framework structure 1 connected to them in close proximity to each other (see FIG. 11).
Therefore, when the load applied to the connected structure B is large and the strength of the beam or column needs to be increased, the thickness of the beam or column can be easily increased by the above-described method.

  Further, as shown in FIG. 12, among the screw holes 2a formed in the base 2, the screw holes 2a that are not used for connection, for example, a threaded rod 11 and a threaded ring 12 are provided. It can also be installed.

  Furthermore, as shown in FIG. 13, a triangular prism-shaped base body 13 can be used instead of the cubic base body 2.

  By setting it as such a structure, the connection angle of the frame structure 1 connected can be set to a predetermined angle, for example, it can be set as the structure which inclined the roof part.

  Further, as shown in FIG. 14, all of the urging member 7 is positioned in the connecting rod 3, or the tip of the urging member 7 is bent inward to form a tongue piece 7b. The tongue piece 7b is made to face the head of the hexagon socket head bolt 5 inserted into the connecting rod 3 at a predetermined interval, so that the hexagon socket head bolt 5 is detached from the bolt insertion hole 3b. This can be prevented.

  In addition to a single cylinder, the frame structure 1 has a double-pipe structure, like the frame structure 1 shown in the lower part of FIG. 1, and is engaged with the biasing member 7 between the inner and outer tubes. A locking means comprising the member 4 may be provided so that it can be expanded and contracted.

  The connected structure constructed according to the present invention can be adjusted by appropriately adjusting the size of each component, for example, a support structure for photographing equipment, a structure constituting a photographing set, a temporary housing or a small-scale structure. There are a wide variety of frameworks, tent frameworks, product display shelves, indoor shelves, kennels, etc.

  Furthermore, if a crimping type fastener (velvet type fastener) is attached to the corner or surface of the framework structure 1, a cover or curtain made of cloth or the like can be easily attached. In particular, when the skeleton structure 1 is mainly composed of square pipes, a crimp-type fastener can be attached so as to straddle two adjacent surfaces of each pipe, so that a cover, a curtain, or the like can be firmly attached.
