Description

  The present invention relates to a joint, and more particularly, to an improvement in a joint that connects a connecting rod extending from a seat opening and closing device that opens and closes a seat that is freely opened and closed to a greenhouse to a stationary part.

  In a greenhouse for plant cultivation, in many cases, in order to adjust the environment in the greenhouse so as to be optimal for the growth of plants, for example, a daylighting sheet is attached to the greenhouse. Open and close freely at the opening.

  In recent years, for the opening and closing of the seat, a seat opening and closing device has been used. However, as the seat opening and closing device, there are various proposals, and in many seat opening and closing devices, the same is applied to the side surface along the longitudinal direction of the greenhouse. Having a pipe provided in the longitudinal direction, and connecting, for example, an end of a sheet that opens and closes an opening formed on the side surface of the greenhouse to the pipe, and winding and rewinding the sheet by rotating the pipe, that is, the sheet Allows opening and closing.

  In the seat opening and closing device disclosed in Patent Document 1, the drive mechanism that moves along the greenhouse rotates the pipe forward and backward, but a guide mechanism that prevents the drive mechanism from rotating is provided in the seat opening and closing device. The guide mechanism is composed of a string member.

Japanese Unexamined Patent Publication No. 2000-88075

  In the seat opening and closing device disclosed in Patent Document 1, there is basically no problem in that the seat can be opened and closed by rotating a pipe with a drive mechanism that does not rotate. In this case, it may be pointed out that there is a minor defect.

  That is, in the above proposal, since the guide mechanism whose tip is connected to the end face of the greenhouse, which is a stationary part, is constituted by a string-like member, there is a concern that the string-like member may deteriorate due to long-term use. It is.

  Therefore, it can be proposed to replace the string-like member with a metal connecting rod, and the tip of the connecting rod can be proposed to be connected to, for example, a joint provided on the end face of a greenhouse that is a stationary portion. The present situation is that no preferred joint has been provided as a joint that can respond to this proposal.

  This invention was devised in view of the present situation, and an object thereof is to provide a joint that is optimal for connecting a connecting rod extending from a seat opening and closing device that opens and closes a sheet stretched on a greenhouse to a stationary part. And

  In order to achieve the above-described object, the joint structure according to the present invention is formed by a fixed bracket, a movable bracket pivotally attached to the fixed bracket, and a socket pivotally supported on the movable bracket. A base portion on which the fixed bracket is fixed to the non-moving portion, a rising portion extending from the base portion, and the movable side bracket extending from the rising portion to the base portion or in parallel with the extension surface of the base portion. It is assumed that the fixed bracket, the movable bracket, and the socket are formed in a universal joint structure, and the socket is detachably connected to the flange member from the outside.

  In the fixed side bracket, since the base is fixed to the non-moving portion, the joint can be disposed as long as the non-moving portion is present.

  In particular, when the greenhouse is formed using a dovetail frame, the dovetail frame can be set as a non-moving part, so that it is easy to select a place where the joint is provided, and the dovetail frame in the base dovetail frame Since fixing to the inner bottom of the groove is possible, a stable connection state of the joint can be realized, and the joint can be attached to and detached from the stationary part.

  In the fixed bracket, since the rising portion extends from the base portion, the operability when fixing the base portion to the non-moving portion can be improved by using the rising portion as a so-called gripping portion.

  In particular, when the stationary part consists of a dovetail frame, the receiving part interferes with the opening in the dovetail frame when the base is fixed to the inner bottom of the groove part in the dovetail frame by selecting the rising height at the rising part. You can avoid doing that.

  In addition, by selecting the rising height at the rising portion, the receiving portion can be positioned above the opening in the dovetail frame, so that the base is fixedly seated on the inner bottom of the dovetail frame in the dovetail frame. It does not hinder the handling operation of the locking line.

  Further, in the fixed side bracket, when the receiving portion is bent so as to be parallel to the extended surface of the base portion, the receiving portion is positioned at a position that is so-called aside from above the stationary portion, and the receiving portion is positioned on the right side. Since it is possible to avoid covering the opening in the groove frame from above, when fixing the base part seated on the inner bottom of the dovetail groove in the dovetail frame when the immovable part is composed of the dovetail frame, This makes it easier to handle the locking line.

  On the other hand, in the joint, the receiving part, that is, the fixed side bracket, the movable side bracket and the socket are connected to the universal joint structure, so that the axial direction of the flange member connected from the outside to the socket is divided. Yes, the convenience of using the joint is not reduced.

1 is a perspective view of a greenhouse equipped with a seat opening and closing device using a joint according to the present invention. It is a perspective view which shows the state by which the joint by this device was attached to the dovetail frame. It is a perspective view which decomposes | disassembles and shows the joint by this invention. It is a longitudinal cross-sectional view which shows a socket with an adapter. It is a longitudinal cross-sectional view which shows the socket of other embodiment.

  Hereinafter, the present invention will be described based on the illustrated embodiment. As shown in FIG. 1, a joint J according to the present invention is formed by using a dovetail frame F (see FIG. 2). The connecting rod R, which is a rod member extending from the seat opening and closing device M mounted on the H, is detachably connected. In the illustrated case, the connecting rod R is provided on the front surface and the rear surface H1 of the longitudinal direction in the greenhouse H. Yes.

  As shown in the figure, the greenhouse H covers the frame from the outside on a dovetail frame F, that is, a frame formed by combining an arched frame F1, a beam frame F2, and a column frame F3 that are structural members. A so-called left and right side surface H2, a roof surface H3, and the above-mentioned wife surface H1 are provided along the longitudinal direction of the greenhouse H.

  The vinyl sheet S is basically a daylighting sheet, and is generally formed of a colorless and transparent synthetic resin material. The strength of the vinyl sheet S is such that it does not break easily when connected to or separated from the frame. Of course, it has weather resistance that lasts for a relatively long time after being connected to the frame, and has durability that does not break easily due to repeated winding and unwinding after connecting to the frame, Furthermore, there is an advantage that the weight is small compared with glass, and it is cheap and easily available.

  And, as is the case with many of this type of greenhouses H, a side window H2 is formed with an open window H4 that actively allows the passage of air without stretching the vinyl sheet S. The sheet is covered with a vinyl sheet S1 that is openable and closable.

  The vinyl sheet S1 is opened and closed by a sheet opening and closing device M. As the sheet opening and closing device M, various proposals have conventionally been made. For example, as with the sheet opening and closing device M in the present invention, a winding pipe P as a pipe is used. In addition to winding or unwinding the vinyl sheet S1, there is a type of unwinding or pulling down the vinyl sheet S1 by folding the vinyl sheet S1 by moving a pipe.

  Incidentally, the vinyl sheet S1 is basically configured in the same manner as the vinyl sheet S described above, but instead of this, for example, it may be an insect repellent net.

  Further, the winding pipe P is connected to the lower end portion of the vinyl sheet S1 as shown by a two-dot chain diagram in FIG. 1, and therefore the vinyl sheet S1 is rotated from the lower end portion by the rotation of the winding pipe P. When the hoisting pipe P unwinds the vinyl sheet S1, the vinyl sheet S1 is so-called unwound from the hoisting pipe P and the lower end of the vinyl sheet S1 hangs down. Cover the window H4 of H2.

  Returning, the sheet opening and closing device M shown in the figure has a drive mechanism including an electric motor and a speed reducer as a drive source, although not indicated, etc., and a winding pipe P is connected to the drive mechanism, and the drive mechanism Is held by the arch-shaped frame F1 that forms the end face H1 via the traveling structure.

  Therefore, in this seat opening and closing apparatus M, the drive mechanism rotates the winding pipe P by energizing the electric motor, and the arrow a in FIG. 1 is synchronized with the movement of the winding pipe P while rotating. Or as shown by b, it moves along the arcuate frame F1, and enables winding and unwinding of the vinyl sheet S1.

  In the figure, the arched frame F1 on which the seat opening and closing device M moves is a so-called double specification in which the reinforcing arched frames F1 are arranged in parallel. In addition to avoiding problems such as bending in the arch-shaped frame F1 to be formed, the holding and movement of the seat opening and closing device M is ensured.

  The seat opening and closing device M is movable along the greenhouse H, that is, along the side surface H2 of the greenhouse H and the roof surface H3 continuous to the side surface H2, but instead, Although not shown, it may be freely movable along a guide provided separately so as to approach the greenhouse H. In short, it may be arbitrarily configured as long as it performs a so-called opening / closing operation of the vinyl sheet S1. .

  Although not shown in the figure, when the seat opening and closing device M is movable along a guide provided separately so as to approach the greenhouse H, the joint J of the present invention is the wife surface of the greenhouse H. Of course, it may be provided in H1.

  By the way, when the seat opening and closing device M moves along the arch-shaped frame F1, in order to stabilize the movement, that is, to suppress the rotation itself by the force of rotating the winding pipe P, R is connected to the stationary part.

  Although not shown in detail, the connecting rod R is preferably formed to be extendable and contractable by a metal outer pipe and a metal inner pipe inserted and retracted into the outer pipe so that the seat opening and closing device M is an arch. It can be said that it can cope with a case where the distance from the non-moving part where the joint J is provided is changed by moving along the frame F1.

  A base end portion (not shown) of the connecting rod R is connected to the seat opening / closing device M, and a distal end portion (not shown) of the connecting rod R is detachably connected to a joint J provided at the stationary portion. It is said.

  By the way, the immovable part is set on the wife surface H1 in the greenhouse H in the figure, but from the intention of the present invention, it is not shown, but for example, it is provided separately so as to be adjacent to the wife surface H1. In other words, it may be a dedicated immovable part composed of columns and beams in the ramen structure.

  In addition, the joint J is made of metal and is a so-called metal fitting in this invention, but the main point is to realize a so-called stable connection to the stationary part of the tip of the connecting rod R. From the viewpoint, the joint J may be formed of, for example, a hard synthetic resin material as long as it has the necessary mechanical strength.

  Under the above premise, the joint J is fixed to the non-moving portion in a fixed state or separable state as shown in FIGS. 2 and 3, that is, fixed so that the fixing to the non-moving portion is possible. A side bracket 1, a movable side bracket 2 pivotally attached to the fixed side bracket 1, and a socket 3 pivotally supported on the movable side bracket 2 are formed. The fixed side bracket 1, the movable side bracket 2 and the socket 3 are formed. Is formed into a universal joint structure, and the socket 3 removably connects the connecting rod R from the outside.

  In the joint J, when the fixed bracket 1, the movable bracket 2 and the socket 3 are formed in a universal joint structure, the axial direction of the connecting rod R connected to the socket 3 from the outside is divided. Therefore, the convenience of using the joint J can be prevented from being lowered.

  In the joint J, the fixed bracket 1 includes a base portion 11 fixed to the stationary portion, a rising portion 12 extending from the base portion 11, and the rising portion 12 to the base portion 11 or the base portion 11. And a receiving portion 13 that extends in parallel with the extended surface of the movable side bracket and pivotally attaches the movable bracket 2.

  Note that the fixed side bracket 1 is formed by bending a single steel plate material having an appropriate thickness that has been die-cut, but if the fixed side bracket 1 functions, Of course, as long as it has each part 11, 12, and 13, it may be formed by other arbitrary measures.

  More specifically, the base portion 11 can correspond to the shape of the non-moving portion where the joint J is provided, that is, generally speaking, the non-moving portion which allows the joint J to be provided has a more or less flat portion. Therefore, it is formed in a flat plate shape so as to enable fixing to the non-moving portion having the flat portion.

  Since the base 11 is formed in a flat plate shape, the base 11 can be fixed to a flat portion of an arbitrary fixed portion, and the joint J can be provided on the fixed portion.

  From the viewpoint of fixing the base portion 11 to the flat portion that is the stationary portion, the base portion 11 is not shown but instead of being formed as a flat plate, the base portion 11 corresponds to the flat portion of the stationary portion. Of course, it may be formed to have.

  On the other hand, as shown in the figure, the immovable portion is a dovetail frame F on the end face H1 in the greenhouse H, that is, a beam frame F2 (see FIG. 1) or a column frame F3 (see FIG. 1). The base 11 is formed so as to realize detachable fixing to the beam frame F2 or the column frame F3.

  In particular, the joint J of the present invention may be provided on a column or a horizontal beam other than the dovetail frame F, and is provided in a fixed state or separable on the column or the horizontal beam. May be.

  Further, other frame members or the like which have a dovetail frame F only for providing the joint J and a groove similar to the dovetail groove (not shown) in the dovetail frame F and enable the joint J to be connected. It is good also as providing the support | pillar or horizontal crossing in the wife surface H1 in the greenhouse H.

  In short, the joint J provided with the wife surface H1 in the greenhouse H as a non-moving portion is easily displaced by, for example, wind and snow, or the connection mechanism when the drive mechanism in the seat opening and closing device M is operated. What is necessary is just to provide so that it may not shift easily by the external force effect | action via R.

  Returning to the above, as shown in FIG. 3, the base 11 has a rectangular shape in plan view, for example, and the length is arbitrarily formed, and the dovetail frame F (see FIG. 2). ) Having a width larger than the width of the opening Fa (see FIG. 2) of the dovetail groove (not shown) and smaller than the width of the inner bottom Fb (see FIG. 2).

  Accordingly, the base 11 remains in a so-called horizontal state and does not enter the dovetail groove in the dovetail frame F, but can enter the dovetail groove in the dovetail frame F by fitting so as to be inclined. .

  Then, the base portion 11 that has once entered the dovetail groove F in the dovetail frame F cannot escape from the dovetail groove in the dovetail frame F in the horizontal state, that is, is not separated from the dovetail frame F.

  In practice, the base 11 formed as described above cannot be maintained permanently just by entering the dovetail groove F in the dovetail frame F and sitting on the inner bottom Fb of the dovetail groove. In this case, as shown in FIG. 2, it is assumed that a fixed fixing state in the dovetail groove of the base portion 11 is realized by using the locking line B.

  When fixing the base 11 with the dovetail groove using the locking wire shape B, the locking wire shape B exerts a spring force in the width direction at the dovetail groove in the dovetail frame F. B becomes so-called spread by a spring force and tends to descend toward the inner bottom Fb of the dovetail along the inner wall of the dovetail, and the base 11 is pressed against the inner bottom Fb of the dovetail by the force at that time. As a result, the base 11 is fixedly fixed to the inner bottom Fb.

  In order to fix the base 11 to the inner bottom Fb of the dovetail, a locking wire B is used in the figure, but the point is that the base 11 may be fixed to the inner bottom Fb of the dovetail. Alternatively, even if the base portion 11 is not fixed to the inner bottom Fb of the dovetail groove, it does not have to be separated from the dovetail frame F. Instead of using, although not shown, for example, a stopper member formed in a vise structure or the like may be used to realize integral connection between the base 11 and the dovetail frame F.

  In addition, the base portion 11 has one or more small holes 11a penetrating the wall thickness at both end portions in the axial direction in order to allow the base portion 11 to be provided in a stationary portion other than the dovetail frame F. The connecting member 14 (see FIG. 3) such as a tapping screw is allowed to pass through the small hole 11a.

  Since the base portion 11 has the small hole 11a and allows the connecting member 14 to be inserted, for example, a tapping screw is allowed to be inserted, the base portion 11 is fixed to a non-moving portion other than the dovetail frame F by using the tapping screw. It becomes possible.

  The rising portion 12 extends from the base portion 11 as shown in the drawing, that is, when the base portion 11 is so-called flat, it is formed to rise upward to fix the base portion 11 to any fixed portion. On the other hand, it is provided to position the receiving portion 13 at a position away from the base portion 11, and in this sense, the receiving portion 13 does not hinder the fixing operation of the base portion 11. It is important to be provided as such.

  In addition, when the stationary part that fixes the base 11 is the dovetail frame F that forms the greenhouse H as in the illustrated embodiment, the base 11 is placed on the inner bottom Fb of the dovetail in the dovetail frame F. It is important that the receiving portion 13 does not interfere with the fixing of the base portion 11 by, for example, the receiving portion 13 interfering with the opening Fa of the dovetail frame F in order to reliably fix the base portion 11.

  For that purpose, the rising part 12 continuing to the base part 11 has a certain height and is set so as to position the receiving part 13 at a height position away from the base part 11.

  The receiving portion 13 extends from the rising portion 12 so as to be parallel to the extended surface of the base portion 11, that is, is positioned outside the dovetail frame F by being bent, The position is prevented from being positioned above the opening Fa.

  In other words, when the receiving portion 13 is positioned outside the dovetail frame F, the dovetail frame F is fixed to the dovetail groove of the locking linear B for fixing the base 11 to the inner bottom Fb of the dovetail groove F. The possibility that the receiving portion 13 hinders the fitting operation is reduced. However, when the receiving portion 13 is positioned above the opening Fa of the dovetail frame F, the fitting operation of the above-described locking linear B can be more or less hindered. Sex will come out.

  However, as long as the locking line B is fitted in the dovetail groove in the dovetail frame F and the fixing to the inner bottom Fb of the dovetail frame F of the base 11 can be realized, the receiving portion 13 is not provided in the dovetail frame F. Of course, it may be positioned above the opening Fa in F. Incidentally, the receiving part 13 has a hole 13a (see FIG. 3) penetrating the wall thickness in the shaft core part, and allows the insertion of a vertical axis 23 described later into the hole 13a.

  The movable bracket 2 includes a base portion 21 that is seated on the receiving portion 13 from above and pivotally pivoted in the horizontal direction when the receiving portion 13 in the fixed bracket 1 is maintained in a horizontal state. When the base portion 21 is in a horizontal state, the base portion 21 has a pair of support portions 22 that stand up and confront each other in the radial direction, and the socket 3 is pivotally supported by the pair of support portions 22. Yes.

  The base portion 21 is pivotally attached to the receiving portion 13 by a vertical axis 23 so as to be rotatable in the horizontal direction. Thus, the base portion 21 is connected to the receiving portion 13, that is, the fixed side bracket 1 through the socket 3. The connecting rod R from the outside can be connected from the entire circumference in the horizontal direction.

  And the base part 21 has the hole 21a (refer FIG. 3) in an axial center part, this hole 21a is aimed at the hole 13a of the lower receiving part 13, and penetrates both the holes 21a and 13a in that state The vertical axis 23 is pivotally attached.

  The longitudinal axis 23 may be arbitrarily formed as long as the base portion 21 is pivotally attached to the receiving portion 13 to allow the base portion 21 to be rotated horizontally. As shown in FIG. In addition, although formed with the round head bolt 23a and the lock nut 23b, instead of this, it may be formed with a rivet (not shown).

  Incidentally, when the vertical axis 23 is formed by the round head bolt 23a and the lock nut 23b, the movable side bracket 2 can be separated from the fixed side bracket 1 by removing the lock nut 23b from the round head bolt 23a. For example, it is advantageous in that it is possible to replace parts when one or both of the fixed side bracket 1 and the movable side bracket 2 are rusted or corroded.

  The support portion 22 pivotally supports the socket 3, thereby connecting the connection rod R from the outside to the receiving portion 13, that is, the fixed side bracket 1 so as to be swingable. Make it possible.

  And the support part 22 has the hole 22a (refer FIG. 3) which penetrates the thickness in the front-end | tip part used as an upper end in the figure, and the socket 3 is supported by the horizontal axis 33 inserted in this hole 22a. It is pivoted to.

  Therefore, in this movable side bracket 2, a universal joint structure is formed together with the fixed side bracket 1 and the socket 3, and as a result, the joint J can freely connect the connecting rod R from the outside to the dovetail frame F. It is possible to connect from the direction.

  The socket 3 enables detachable connection of the tip of the connecting rod R (see FIG. 2), and allows the connecting rod R to be inserted in a separable manner, that is, to allow the tip of the connecting rod R to be inserted and removed. While having the insertion part 31 formed in the cylinder shape, the pivot part 32 connected to this insertion part 31 and holding the insertion part 31 is pivotally attached to the support part 22 under the distribution of the horizontal shaft 33.

  When the diameter of the connecting rod R is large (see FIG. 4), the insertion portion 31 is formed to have an inner diameter that allows insertion of the tip portion of the connecting rod R having a large diameter, and in the diametrical direction. The pair of set screws 34 are screwed, and the pair of set screws 34 sandwich the tip of the connecting rod R inserted into the insertion portion 31 from the diameter direction, and from the insertion portion 31 to the connecting rod R. The tip is prevented from coming off.

  Further, as shown in FIG. 4, the socket 3 has an adapter 35 made of a synthetic resin material that is separably held by the insertion portion 31, and when this adapter 35 is attached to the insertion portion 31, this adapter It is assumed that insertion of the tip of the connecting rod R from the outside having a small diameter to 35 is allowed.

  The adapter 35 has a notch 35a (see FIG. 3) that allows the tip portions of the pair of set screws 34 to be inserted, and the tip of the pair of set screws 34 passes through the notch 35a. By allowing the connecting rod R to be in contact with the insertion portion 31, it is possible to integrally connect the connecting rod R to the insertion portion 31.

  The adapter 35 may be made of metal in the same manner as the socket 3 instead of being made of a synthetic resin material. However, when made of a synthetic resin, the adapter 35 has an advantage that it can be obtained at a low price. This is advantageous in that it is possible to avoid the occurrence of noise caused by metal contact.

  Incidentally, as shown in FIG. 3, the insertion portion 31 of the socket 3 has a pair of screw holes 31 a into which the pair of set screws 34 are respectively screwed, but the tip of the connecting rod R by the set screw 34. Of course, as long as it is possible to integrally connect the insertion part 31 to the insertion part 31, the number of the set screw 34 is one, and the number of the screw holes 31 a may be one.

  As shown in FIG. 3, the horizontal shaft 33 for pivotally attaching the pivot portion 32 of the socket 3 to the support portion 22 is formed of a hexagon head bolt 33a and a lock nut 33b. Instead of this, although not shown, it may be formed of rivets. The pivot portion 32 of the socket 3 has a hole 32a through which the horizontal shaft 33 is inserted and aimed at the hole 22a in the support portion 22.

  By the way, when the horizontal shaft 33 is formed of the hexagon head bolt 33a and the lock nut 33b, the movable bracket 2 and the socket 3 can be separated by removing the lock nut 33b from the hexagon head bolt 33a. For example, it is possible to replace parts when one or both of the movable bracket 2 and the socket 3 are rusted or corroded.

  FIG. 5 shows a socket 3 according to another embodiment. The socket 3 is formed into a plurality of cylinders into which the tip end portions of the connecting rods R having different diameters are inserted, that is, in a shape of two cylinders in the drawing. The insertion portions 31 and 36 are in series.

  And the pivot part 32 which inserts the horizontal axis | shaft 33 which pivotally supports this socket 3 to the movable side bracket 2 is supposed to be provided in the intermediate part of the insertion parts 31 and 36 of both sides said.

  Even in this socket 3, the insertion portion 36 has a pair of screw holes 36 a, and a pair of set screws 34 (see FIG. 3) are screwed into the pair of screw holes 36 a, so The tip end portion of the connecting rod R inserted is sandwiched from the diameter direction to prevent the tip end portion of the connecting rod R from coming off from the insertion portion 36.

  In the case of this embodiment, the adapter 35 is unnecessary, the work of attaching and detaching the adapter 35 is unnecessary, and the number of parts can be reduced as compared with the case of the embodiment shown in FIGS. Is advantageous.

  As described above, the greenhouse H is formed in a single building structure. However, according to the intention of the present invention, the plurality of greenhouses H have the same longitudinal direction and are connected by omitting the formation of the side surface H2. It may be formed in a continuous building structure that does not become an obstacle to using the joint J.

  Moreover, in forming the frame of the greenhouse H, although not shown, a column member or a beam member made of a structural member other than the dovetail frame F is, for example, along the beam frame F2 or the column frame F3. Of course, it may be provided instead of the beam frame F2 or the column frame F3 as appropriate, and even if these column materials and beam materials are immovable portions where the joints J are provided, Of course.

  In the above description, the joint J is fixed to the dovetail frame F using the locking line B. However, at this time, the locking line B is used for the dovetail frame F in advance. The vinyl sheet S is normally connected, and it is a matter of course that the joint J of the present invention can be fixed to the dovetail frame F even in this state.
