DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deployment truss used as a structure of a space station or the like and an apparatus for automatically expanding and contracting the deployment truss.

More particularly, the present invention relates to a telescopic deployment truss composed of a plurality of essentially rigid members;
The present invention relates to a telescopic device that automatically and repeatedly expands and contracts the deployment truss.

[0003]

2. Description of the Related Art Hitherto, as a structure that can be deployed as a structure of a space station or other spacecraft, there is a stretchable structure called an extension mast or a deployment truss. Such a structure is launched into orbit while being housed in a small volume, and deployed in outer space to form a structure having a predetermined shape. As this extension mast,
There is a coil type using an elastically deformable member as a longitudinal member. Further, as the deployment truss, there is a high-rigidity truss in which essentially rigid members are pivotally connected to each other so as to be freely deployable.

[0004] In the former coil-shaped extension mast, the vertical member is bent in a coil shape when stored, is stored in a small volume, has high storage efficiency, and has a simple structure. But,
Such a type of extension mast has a disadvantage that rigidity at the time of deployment is low. In addition, the latter deployment truss
Although the storage efficiency is low and the structure is complicated as compared with the coil type, the rigidity at the time of deployment is high.

[0005] The latter deployment truss is not only used as a fixed structure after being deployed in space, but also a structure that is repeatedly expanded and contracted in space, for example, for deployment of a mesh antenna. It is also used as a boom, a deployment boom for solar cell panels, and the like.

[0006] The present applicant has disclosed such a deployed truss as disclosed in Japanese Patent Application No. 1-186780 and Japanese Patent Application No.
No. 191091 ". In the deployment truss according to these applications, a plurality of longiron members whose intermediate portions are hinged to each other are arranged between a plurality of batten members. When the extension mast is stored, the pair of longiron members are folded radially inward of the deployment truss, and the deployment truss is shortened in the vertical direction. When the deployment truss is deployed, these paired longiron members are deployed in a substantially straight line in the vertical direction, and are locked in a straight line in an over-center state with each other. The deployment truss of this type has a high rigidity and a relatively simple structure because the longiron member is locked in the deployed state by the over center.

[0007] However, in such a deployment truss, since the intermediate portion of the longiron member is connected by a hinge,
The structure of this portion becomes relatively complicated, and the rigidity at this portion is inevitably reduced. If possible, the longiron member between the batten members is preferably a single member.

Further, when such a deployment truss is repeatedly extended and contracted by a telescopic device and used as a telescopic boom or the like, since the above-mentioned longiron member is folded inward in the radial direction, a hose and an electric wire are provided in the deployment truss. When the deployment truss is used, or when the inside of the deployment truss is used as a passage for moving objects or personnel, there is a disadvantage that the folded longiron member interferes.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the rigidity of a longiron member disposed between batten members can be increased as a single member to further increase rigidity.

The deployment truss 1 includes a plurality of batten members 11, and these batten members 11 have a substantially triangular shape made of a shape member. And, between these batten members 11, the Longilon 1 extends along the longitudinal direction.
2 are arranged. These longirons 12 connect the vertex portions of the triangular batten member 11. A diagonal member 13 is provided diagonally between adjacent vertexes of the batten member 11. These diagonal members 13 are composed of two tube members slidably fitted to each other, and when extended to the maximum length thereof, a stopper or the like comes into contact with the diagonal members 13 so as not to extend beyond the maximum length. It is configured. These members constitute a deployment mast 1 having a truss structure having a triangular cross section as a whole.

The above-mentioned batten member has a triangular frame shape obtained by assembling a frame member 15 made of, for example, three mold members into a triangular shape. In addition, the above-mentioned longiron member 12 is constituted by an integral hollow tube member. One end of the longiron member 12, in this embodiment, the lower end is pivotally attached to the vertex of the batten member 11 by a hinge mechanism 16. The direction of rotation of the hinge mechanism 16 is such that these longiron members 16 move in the direction of the frame member 15 of the
This is a direction that rotates in a plane including.

The other end of the longiron member 12, that is, the lower end in this embodiment, is slidable along the frame member 15 of the batten member 11 by the following slide mechanism. FIG. 2 is a cross-sectional view of the frame member 15 of the batten member 11, and FIGS. 3 and 4 are vertical cross-sectional views of the frame member 15. The frame member 15 has a substantially U-shaped hollow cross-sectional shape whose lower side surface is open. The inside of the hollow frame member 15 is formed in a slide guide portion, that is, a guide groove 14. Roller grooves 17 are provided on inner surfaces of both side walls of the frame member 15.
Are formed. In addition, a slide shaft 19 extending in a lateral direction is attached to an upper end portion of the above-mentioned longiron member,
Guide rollers 18 are rotatably attached to both ends of the slide shaft 19, respectively. These guide rollers 18 are rotatably fitted in the roller grooves 17. Also, the width of the inner surface of the frame member 15 described above,
That is, the width of the above-mentioned guide groove 14 is formed to be larger than the diameter of the above-mentioned longiron 12, so that these longiron members 12 can be accommodated in these frame members 15.

A lock mechanism 20 as shown in FIGS. 3 and 4 is provided at the end of the frame member 15, that is, at the apex of the triangular batten member 11, respectively. The upper end of the longiron member 12 erected in the vertical direction is fixed to the batten member 11. In the figure, reference numeral 21 denotes a fitting member. The fitting member 21 is mounted in the end of the guide groove 14 of the frame member 15 and a fitting groove 22 is formed. Then, the slide shaft 19 at the upper end thereof is fitted into the fitting groove 22 in a state where the above-mentioned longiron member 12 stands upright along the vertical direction. A lock claw 23 is pivotally attached to the end of the frame member 15 so as to be rotatable.
3 is urged by a spring 25 and engages with the slide shaft 19 when the slide shaft 19 fits into the fitting groove 22, and fits the slide shaft 19 into the fitting groove 22. It is configured to be fixed in the combined state. A release lever 2 is provided at the base end of the lock claw 23.
4 are integrally provided. The back of the release lever 24 is formed in a sloped shape. When another member, for example, a lock release member abuts on the release lever 24, the lock claw 23 rotates against the urging force of the spring 25. ,
The engagement of the slide shaft 19 at the upper end of the longiron member 12 is released.

The operation of the deployment truss of the present invention configured as described above will be described. In the housed state, that is, the shortened state as shown in the lower part of FIG.
The upper end of the guide groove 1 of the batten member 11
The lock mechanism 20 is rotated so as to move to an end opposite to the lock mechanism 20, and these longiron members 12 are positioned laterally so as to be substantially parallel to the frame member of the batten member 11. In this embodiment, the longiron member 12 is housed in the guide groove 14 of the frame member 11 in this state, so that the respective batten members 11 are in close contact with each other as shown in the lower part of FIG. In this state, the diagonal member 13 is shortened and stored along the inner side surface of the frame member 15 of the batten member 11.

Next, when the unfolded state, ie, the extended state shown in the upper half of FIG. 1, is reached, the batten member 11 is sequentially pulled up. In this case, the upper end of the above-mentioned longiron member moves in the guide groove 14 by the guide roller 18 rolling in the roller groove 18 and stands upright from the horizontal direction to the vertical direction. Then, when these longiron members 12 stand upright along the vertical direction, the slide grooves 1 at the upper end portions of these longiron members 12 are formed.
9 is fitted into the fitting groove 22 of the fitting member 21, and in this state, the lock claw 23 is engaged with the slide shaft 19 by the urging force of the spring 25, and the slide shaft 19 is fitted into the fitting member 21. Engage with the mated state.

In this state, each of the diagonal members 13 is diagonally arranged in a state of being fully extended to its maximum length. In this case, these diagonal members 13 are inserted into the fitting grooves 22 of the lock mechanism 20 before the above-mentioned longiron member 12 stands upright to a position along the longitudinal direction, that is, the slide shaft 19 at the upper end of these longiron members 12. The dimensions of each part are set so as to extend to its maximum length shortly before fitting. Therefore, when the diagonal members 13 further erect from the state in which the diagonal members 13 have been extended to the maximum length, these diagonal members 13 further extend elastically, and in this state, the upper end of the longidron member 12 is locked by the lock mechanism 20. Locked. Therefore, when the deploying truss is deployed, an internal load acts on the deploying truss by the elastic force of the diagonal member 13, and the play of the hinge mechanism 16 and other movable parts is removed, and each member is removed. Since the initial load will act on
The rigidity of the deployment truss is increased.

FIGS. 5 to 7 show a deployed truss according to a second embodiment of the present invention. This embodiment is described in FIG.
Although the configuration is substantially the same as that of the deployed truss of the first embodiment shown in FIG. 4, the following parts are different.

That is, in the second embodiment, slit-shaped sliding grooves 31 are formed on both side walls of the frame member 15 of each batten member 11, respectively. A sliding pin 32 is attached to the upper end of each longiron member 12, and these sliding pins 32 protrude outside the frame member 15 through the inside of the above-mentioned sliding groove 31. The sliding pins 32 slide in the sliding grooves 31 to guide the upper ends of the longiron members 12.

A lock mechanism 33 is provided at each end of the frame member 15. This locking mechanism 33
Is substantially the same as that of the first embodiment, but the lock claw 34 is pivotally mounted so as to rotate in a horizontal plane. The lock claw 34 is urged by a spring 35 in the same manner as described above, and its release lever 3
6 is an external object, for example, a release member 3 of a telescopic device.
7, the engagement of the sliding pin 32 by the lock claw 34 is released.

In the second embodiment, the diagonal member 41 has a structure as shown in FIG. The diagonal member 41 includes a pair of rod members 42, each of which has a sliding member 43 attached to one end thereof, and these sliding members 43 are slidably fitted to each other. I agree. Rod ends 44 are attached to the other ends of the rod members 42, that is, both ends of the diagonal member, respectively.
Via these rod ends 44, it is pivotally attached to the above-mentioned batten member 11 so that rotation is possible. When the diagonal member 41 is extended to the maximum length, the diagonal member 41
7 abut against each other as shown in FIG. 7 to act as a stopper, preventing the diagonal member 41 from extending beyond this maximum length.

In the above-described deploying truss, each of the longiron members 12 rotates in a plane including each frame member 15 of the batten member 11 during expansion and contraction. Does not protrude.
Therefore, the inside of the deployment truss can be effectively used as electric wires, pipes, and other passages.

For example, FIGS. 8 and 9 show an example in which the wire harness 51 is accommodated in the deployment truss. The wire harness 51 has a belt shape and is configured to bend only in the direction of the surface including the frame member of each of the batten members 11. Each of the wire harnesses 51 has a mounting member 53 on the inner side surface of each frame member of the batten member 11.
Mounted through. In the middle of the wire harness 51, two harness trays 52 are provided.
Is installed. These harness trays 52
The purpose is to increase the lateral rigidity of the intermediate portion of the wire harness 51 and prevent the wire harness 51 from shifting in the lateral direction and being caught between the batten members 11 when the deployment truss expands and contracts.

The extension and shortening of the deployment truss are performed by a telescopic device as described later. In the case where such a deployment truss is used as a fixed structural member, the truss may be launched into space in a shortened state and then extended only once. In such a case, the telescopic device is not always necessary. For example, an urging mechanism that urges the above-mentioned longiron member in the upright direction is provided, and the deployment truss is shortened against the urging force of this urging mechanism. The state may be locked, and after launching into space, the lock may be released and the deployment truss may be deployed by the biasing mechanism.

Further, the upper end of the longiron member may be pivotally attached to the batten member by a hinge mechanism, and the lower end may be slidably guided by the batten member. Further, the upper end of the upper Ronjiron member and the lower end of the lower Ronjiron member are pivotally attached to the batten member by a hinge mechanism, respectively, and the lower end of the upper Ronjiron member and the lower end of the lower Ronjiron member. The upper end of the longiron member may be slidably guided by a single batten member. With such a structure, the lock mechanism can be shared by the two longiron members,
The structure becomes simple.

Next, a device for expanding and contracting the deployable truss as described above will be described with reference to FIGS. This apparatus is an apparatus for expanding and contracting the deployment truss of the first embodiment shown in FIGS.

In the case of expanding and contracting with such a device, a driving unit, that is, an elevating driving pin 61 is provided at the apex portion of each of the batten members 11 on the deployment truss as shown in FIG. At the upper end of each longiron member 12, an upright drive pin 62 projecting in the lateral direction is attached.

FIG. 10 shows a state in which a deployment truss is attached to the telescopic device, and FIG. 11 shows only this telescopic device. In the drawing, reference numeral 101 denotes a base frame, and the base frame 101 has a triangular frame shape substantially similar to the shape of the batten member 11 of the deployment truss.

Three guide frames 102 project from each vertex of the base frame 101. The upper ends of the guide frames 102 are connected by a connection frame 104 and reinforced by a diagonal member 107. The deployment truss is stored in a shortened state in a lower part in a space surrounded by the base frame 101 and the guide frame 102. Each of the batten members 11 of the deployment truss is guided by these guide frames 102 so as to be movable in the vertical direction.

In each of the guide frames 102, a drive screw 103 is supported rotatably along a longitudinal direction. The lifting drive pins 61 protruding from the respective batten members 11 of the deployment truss are
The lifting drive screw 103 is configured to be fitted. These lifting drive screws 103 are
As shown in FIG. 13, an integral rotating shaft 110 is connected to the lower end. In addition, the above frame-shaped base frame 10
1, a connecting shaft 111 is rotatably supported, and these connecting shafts 111 are rotatable via gears 115 and 116.
And the drive screw 103. Also,
A drive motor 113 is connected to the connection shaft 111 via gears 112 and 114. The drive motor 113 drives the rotary shaft 110 and the drive screw 103 to rotate in both forward and reverse directions via the connection shaft 111. Therefore, the unfolding truss stored in the lower part of the telescopic device in a shortened state is rotated by the forward rotation of the drive screw 103 so that the elevation drive pin 61 of each batten member 11 is driven by the drive screw 103.
12 and is sequentially lifted from the upper batten member 11 as shown in FIG. 12, and the longiron member 12 stands up and is sequentially extended. In addition, these drive screws 103
The reverse rotation causes the batten member 11 of the deployed mast in the extended state to be sequentially pulled down from below, and the longiron member 12 to turn laterally and be sequentially shortened from below.

Further, corresponding to the upper end of each of the guide frames 102, a longiron member guide mechanism is provided on the edge of the connection frame 104. As shown in FIG. 11 and FIG. 14, the longiron member guide mechanism has a longiron member guide groove 105. The longiron member guide groove 105 includes, for example, two guide plates 121,
It is a groove formed between the grooves 122. When the batten member 11 is pulled up by the drive screw 103 and the deployment mast is extended, the upright drive pin 62 protruding from the upper end of the longiron member 12 is inserted into the longiron guide groove 105. The extended truss member 12 is engaged with the lock mechanism 20 of the deployment truss.
Is forcibly driven to be close to the lock mechanism, and is securely locked to the lock mechanism. Conversely, when the deployment truss is shortened, the upright drive pin 62 is fitted into the longilon member guide groove from above, and the upper end of the longilon member 12 is forcibly disengaged from the lock mechanism 20. Will be moved and the lock will be released securely,
These longiron members 12 are surely rotated in the lateral direction.

At the upper end of the guide frame 102, a lock release mechanism is provided. The lock release mechanism includes a lock release member 106 provided inside the upper end of the guide frame 102. Therefore, when the deployment truss in the extended state is shortened and the batten member 11 passes through the position of the unlocking member 106, the unlocking member 106 comes into contact with the release lever 24 of the lock claw 23 of the locking mechanism of the deployment truss. The slide shaft 1 at the upper end of the longiron member 12 by the lock claw.
Release the engagement of 9 and release the lock.

When such a deployment truss is combined with the telescopic device as described above to constitute a device such as a telescopic boom, the deployable truss is extended with respect to the telescopic device in a state where the deployable truss is fully extended. It may be necessary to secure it securely. In such a case, FIG.
A fixing mechanism 128 as shown in FIG. That is, the fixing mechanism 128
The fixing beams 162 and 161 are attached to the upper end and the intermediate part of the guide frame 102 of the above-mentioned telescopic device. A fixing projection 169 protrudes from the second lower batten member 11, and the lowermost batten member 11
The fixing projections 165 are also protruded.

The fixing projection 169 of the second lower batten member is connected to the upper fixing beam 16.
2 is configured to contact the lower surface. A pin 164 projects from the upper surface of the fixing projection 169, and the pin 164 is configured to be fitted into a fitting hole formed in the fixing beam 162.

Further, the fixing projection 1 of the lowermost batten member
Numeral 65 is configured to contact the lower surface of the intermediate fixing beam 161. The fixing beam 161 is provided with a fixing lock member 167 which is moved by a driving mechanism (not shown). The fixed lock member 167 is configured to abut on the lower surface of the fixed protrusion 165 abutting on the lower surface of the fixing beam 161.

According to such a fixing mechanism 128, when the deployment truss is fully extended, the second lower batten member 11 is fixed to the fixing beam 162 by the fixing projection 169 and the pin 164, and the lowermost step. The fixing projection 165 of the batten member 11 is pressed between the fixing beam 161 and the fixing lock member 167. Accordingly, the second lowermost batten member and the lowermost batten member are fixed to the top telescopic device side, and the deployment truss and the telescopic device are integrally fixed.

The expansion and contraction device of the present invention is not limited to the above embodiment. For example, in the case of the expansion and contraction device of the deployment truss according to the second embodiment as shown in FIGS. 5 to 7, both ends of the sliding pins 132 projecting from the side surfaces on both sides of the batten member 11 are attached. It may be used as an upright drive pin 62 for a longiron member. In this case, it is needless to say that the structure of the longiron member guide mechanism must be changed accordingly.

Further, in the above-mentioned telescopic device, since the base frame has a hollow frame shape, when forming a passage such as an electric wire or a pipe in the deployment truss, the electric wire or the pipe is connected to the base frame. Can be arranged through. However, when these electric wires, pipes, and the like are not arranged, the base frame need not be frame-shaped.

Furthermore, the deployable truss of the present invention does not need to have a triangular cross-section, and may have a polygonal or other shape. In such a case, the expansion and contraction device is also shaped in accordance with the shape of the deployable truss. Of course.

[0044]

As described above, the deployable truss of the present invention is essentially composed of a rigid member, and furthermore, there is no joint such as a hinge mechanism in the middle of the longiron member, and these are integral members. In the unfolded state, an internal initial load is acting. Therefore, an extremely rigid deployment truss can be configured.

Further, since the end of the longiron member slides with respect to the batten member and turns in the lateral direction, the longiron member does not project into the deployment truss during expansion and contraction. Therefore, the structure is simple and the inside of the deployment truss can be effectively used as a passage for electric wires, pipes, and the like.

Further, according to the telescopic device of the present invention, such a deployment truss can be automatically extended and retracted, and this deployment truss can be used as a movable member such as a telescopic boom.

Further, the device of the present invention has a simple structure in which the batten member of the deployment truss is simply moved by the driving screw, and the operation is highly reliable.
