DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary gate,
In particular, the present invention relates to improvement of a temporary gate used as an entrance gate in a temporary enclosure such as a construction site or a landing gate in a temporary scaffold.

[0002]

2. Description of the Related Art For example, at a construction site, it is necessary to enclose a site from the viewpoint of safety management until a building is completed. In this case, a temporary enclosure provided around the site is a temporary enclosure. The temporary enclosure is also provided with an entrance as an opening.

At the entrance, an entrance gate having a certain degree of durability and having a structure designed so that it does not easily open and close or fall down by an external force such as wind is provided, that is, a temporary gate. And

There have been various proposals for this temporary gate. For example, while the door body is formed in the form of a foldable accordion door, the door body is formed of a gate-shaped support frame. There is a hanging door type which is assumed to be hung by an upper horizontal rail portion.

[0005] The hanging door type temporary gate has an advantage that the door body is suspended at the top end thereof, so that the door body can be easily opened and closed. However, the temporary support gate is provided upright. It has been pointed out that the horizontal rail portion is disposed above the gate, so that the upper space of the so-called opening is easily restricted.

On the other hand, as a conventional temporary gate, there is a telescopic door type in which a door body formed in the form of a telescopic door is configured so as to be able to expand and contract in the horizontal direction by rolling of a caster held at the lower end. There is something.

[0007] In this temporary door of the telescopic door type, one end of the door body is fixedly connected to one of the so-called support portions provided on both sides, and the other end is connected to the movable end. It is set so as to be connected to the other support part in a separable manner.

The telescopic door-type temporary gate has an advantage that the above-mentioned drawbacks such as the restriction of the upper space in the hanging door type are not caused.

[0009] However, the temporary doors of the telescopic door type provided so far are made of steel and are heavy in weight from the viewpoint of ensuring durability, so that handling such as transporting is difficult. The problem described above has been pointed out.

[0010] In addition, in the case of a telescopic door type temporary gate provided so far, no consideration has been given to improving the installability of this type of temporary gate from the viewpoint that this type of temporary gate is a so-called temporary material. In many cases, there has been pointed out a problem that the workability at the time of installation is poor.

In view of the fact that the temporary gate is also a temporary material, the telescopic door type temporary gate provided so far is formed so as to be suitable for use as an entrance gate in a temporary enclosure. For example, it is pointed out that a defect is not formed so as to be able to be used as a temporary gate as a landing gate in a temporary scaffold, although the situation is similar.

That is, as described above, the conventional telescopic door-type temporary gate has a tendency to be made of steel material and has a tendency to increase in weight, so that it is used as a landing gate in a temporary scaffold that does not want to overload. Is inherently unsuitable.

Also, as described above, the conventional telescopic door-type temporary gates tend not to take into account the ease of installation, so if they are diverted to be installed as landing landing gates at a large number of temporary scaffolds, This requires a great deal of time and labor, which hinders a reduction in temporary construction costs that contribute to a reduction in construction costs.

The present invention has been made in view of the above circumstances, and has as its object to provide a telescopic door-type temporary gate which does not limit the space above the opening.
In addition to facilitating handling such as transportation, improving the workability at the time of installation, and enabling the diversion,
An object of the present invention is to provide a temporary gate which is optimal for use as an entrance gate in a temporary enclosure such as a construction site or a landing gate in a temporary scaffold.

[0015]

In order to achieve the above-mentioned object, a first structure of the present invention is provided by disposing a caster at a lower end which is disposed between a pair of opposing support portions and is formed in the form of a telescopic door. In a temporary gate having a single door body to be held, the door body has a frame body erected at both lower ends thereof via casters for holding at respective lower ends, and each frame body is While having a plurality of holder members arranged at the same position in the vertical direction, the holder member in the one end frame body is fixedly connected to one support portion with an appropriate locking body, It is assumed that the holder member of the frame body at the other end is separably connected to the other supporting portion by an appropriate connecting body.

In the temporary gate according to the first configuration, specifically, while the holder member is formed of a tubular body, the other support portion is aimed at the holder member of the frame body at the other end. It is assumed that a receiving member formed of a cylindrical body is disposed in such a state as to be performed, and the connecting body is formed of a hook having a base end portion and a distal end portion selectively inserted into the cylindrical body and the cylindrical body.

Further, in order to achieve the above-mentioned object, a second configuration of the present invention is provided by connecting a pair of opposing supporting portions, forming a telescopic door, and connecting a caster at a lower end thereof in series. In the temporary gate having a plurality of door bodies, each of the door bodies has a frame body erected at both ends thereof via casters held at the lower ends thereof, and each frame body has Has a plurality of holder members arranged at the same position in the vertical direction, and the holder members in each frame body that is both ends in the door body connected in series are fixed to the support portion with appropriate locking members. While being connected, it is assumed that the holder members in each of the frame bodies facing each other between the adjacent door bodies are connected in a separable manner by an appropriate connecting body.

In the temporary gates according to the first and second configurations, specifically, a tip portion in which a locking member is inserted into the cylindrical body while the holder member is formed of a cylindrical body. It is assumed that the insertion member is provided on the support portion.

Further, in the temporary gate according to the second configuration, specifically, the base member and the distal end portion in which the connecting member is inserted into the cylindrical body while the holder member is formed of a cylindrical body. And a hook having the following.

[0020]

[Function] Therefore, when the door body is made of aluminum material,
This makes it possible to reduce the weight as compared with the case where it is formed of a steel material, and to reduce the total weight of the temporary gate having the door body.

Further, since the door body has the same configuration at both ends, the direction of determining the front and back is eliminated.
Therefore, it is possible to dispose the front and back sides of the pair of opposed support parts without distinction.

The connection of the door body to the support portion is made by inserting the holder member into, for example, a cylindrical body that opens vertically, while the locking body has a tip end portion that is inserted into the cylindrical body. In the case where it is assumed that the insertion member is disposed on the support portion while the insertion member is disposed on the support portion, the frame member forming the end of the door body is lifted, and the like, and the cylindrical member serving as a holder member disposed there is provided. This is realized by inserting the distal end portion of the insertion body, which is a locking body disposed on the support portion, into the body.

At this time, the door body is inseparably connected to the supporting portion, that is, fixedly connected.

The connection of the door body to the support portion is such that the connecting member is, for example, an inverted U-shaped hook having a base end and a front end, and the hook is provided on the support portion side. When a receiving member that allows the connection of the cylindrical member is provided, the connecting member can be connected to the cylindrical member by the hook.

Further, when the door body is connected to another adjacent door body, the connecting body is a hook formed in an inverted U-shape. It is possible to connect with each other.

At this time, the door main body is linked to a state in which the door main body can be separated from the support portion, that is, a state in which the door main body can be opened and closed.

As a result, since the door body is formed to be extendable, the door body is opened by an opening operation for bringing the other end of the door body closer to the one end, and conversely, the other end of the door body. The door body is closed by a closing operation that moves the end away from the one end.

When the door body is opened and closed, the caster held at the lower end of the door body rolls so that the door body smoothly expands and contracts.

[0029]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. As shown in FIG. 1, a temporary gate according to an embodiment of the present invention
It has a single door body 2 disposed between the two.

In this embodiment, for example, the support portion 1 is formed so as to be integrally connected to an opening (not shown) formed in a temporary enclosure (not shown) by appropriate means. The support column 11 has a base plate 12 at a lower end thereof.
1, that is, the support portion 1 is set so as to be able to temporarily become independent.

In the case where the support column 11 is continuously connected to the opening, a so-called single pipe is generally used for forming the temporary enclosure, so that the support column 11 is clamped (see FIG. (Not shown), and it is preferable that the clamp is used to continuously connect to an opening formed in the temporary enclosure.

In the present invention, the door body 2 is formed of an aluminum material in the form of a telescopic door, and is set so as to be able to expand and contract in the lateral direction while holding the caster 3 at the lower end. It is stated that the support portion is disposed solely between the support portions 1 and 1.

In the illustrated example, the door main body 2 is formed as a single unit. However, as in the other embodiment shown in FIG. A plurality of (two in the illustrated example) may be arranged in series, and a case where a plurality of door bodies 2 are arranged will be described again.

The door body 2 is formed as a telescopic part 21 which makes a so-called main body part expandable and contractable in the horizontal direction. Each of the frame members 22 has an upright frame body 22.

The door body 2 has a caster 3 at the lower end of an auxiliary frame 23 connected to the telescopic part 21 in the illustrated example, and the telescopic part 21 is so-called loosely lowered at the center thereof. Care is taken not to be a problem.

It is preferable that the caster 3 has a so-called double tire structure in order to prevent the frame body 22 and the auxiliary frame 23 from falling.

The expansion and contraction portion 21 is formed by assembling a large number of frame members 21a in an oblique lattice with a large number of pivot pins 21b, and the left and right ends of the expansion and contraction portion 21 in the drawing. Each frame body 22 is connected by connecting pins 24 at both ends.
It is said to be linked to.

On the other hand, each frame body 22 has a plurality of steps on its end face on the side of the expansion and contraction section 21, that is, in the illustrated example, the upper, lower, lower
It has a bracket 25 serving as a step, and the connection pin 24 is directly pivoted to the lowermost bracket 25.

On the other hand, the uppermost bracket 25 and the middle bracket 25 have a guide 26 extending in the vertical direction.
4 so as to be movable in the up-down direction, so that
The connection to one frame body 22 is realized.

As described above, by connecting the connecting pin 24 to the guide 26, the guide 2
6, the connecting pin 24 is moved up and down along the direction 6, and the expansion and contraction of the expansion and contraction section 21 is allowed in a state where the change in the length in the vertical direction during expansion and contraction of the expansion and contraction section 21 appears larger at the upper end than at the lower end. Will be done.

The structure of the connecting pin 24 and the guide 26 is also provided at the upper end of the auxiliary frame 23.

By the way, each of the frame bodies 22 is provided at the support portion 1, that is, at the end face on the support column 11 side.
One end frame body 2 having a plurality of holder members 4 arranged at the same position in the vertical direction, and being the left end in the figure.
The holder member 4 in FIG. 2 is fixedly connected to one of the support portions 1 on the left side in the figure, that is, the support columns 11, with an appropriate locking body 5, and the other end frame on the right side in the figure. Body 22
The holder member 4 is connected to the other support portion 1 on the right side in the drawing, that is, the support column 11 so as to be separable by an appropriate connecting body 6.

As shown in FIGS. 2 and 3, the holder member 4 has a cylindrical body 4 which is opened at upper and lower ends in this embodiment.
1 and is integrally connected to the frame body 22 by using a tapping screw 42.

When the tapping screw 42 is screwed in, a through-hole 41a vertically opened in a so-called side portion of the tubular body 41 is used.

The positions of the holder members 4 in the vertical direction are set so as to be at the same level in the frame members 22 at both ends, and the frame members 22 at both ends are opposed to any of the support portions 1. We consider that it may be good.

That is, the direction of determining the front and back of the door body 2 is eliminated, and when the door body 2 is disposed between the pair of support portions 1 and 1, the door body 2 can be disposed without distinction between the front and back. , So that the workability can be improved.

As shown in FIG. 2, the locking member 5 is an insertion member 5 formed in an L-shaped hook shape.
The insertion member 51 has a distal end portion 51a which is set upward and is inserted into the cylindrical member 41 serving as the holder member 4.

In the insertion body 51, the tip 51a is connected to the tip of the horizontal base 51b.
It is assumed that the base end of the horizontal base 51b is integrally connected to the support column 11 via a bracket 51c using a tapping screw 51d.

It is to be noted that the locking body 5 may be connected to a clamp instead of the illustrated example, and may be held on the support column 11 via the clamp. By making the directions of the distal end portions 51a opposite to each other between the stoppers 5, integrated connection by the stoppers 5 is realized, and so-called detachment can be prevented in advance.

Therefore, in the illustrated example, the connection between the locking member 5 and the holder member 4 is made when the distal end portion 51a of the insertion member 51 is inserted into the cylindrical body 41 (the state shown in FIG. 2). It will be enough.

In this case, while the insertion body 51 is provided on the support column 11 as the fixed side, the tubular body 41 is provided on the frame body 22 as the movable side, and the frame body 22 is so-called deformed. The distal end 51a of the insertion body 51 can be inserted into the cylindrical body 41 by an operation of lifting and lowering the frame body 22 since the frame body 22 is connected to the elastically expanding and contracting part 21 having high flexibility.

In this embodiment, since the door body 2 is made of aluminum and is lightweight, the operation of lifting and lowering the frame body 22 can be easily performed. No other members are required for maintaining the connected state, so that it is advantageous in that the management becomes easy.

Further, unless the above-mentioned operation is forcibly performed, the connection state between the insertion body 51 and the cylindrical body 41 is not released, and therefore, a so-called ordinary use state, that is,
When the door body 2 is only pulled in the lateral direction, it is advantageous in that the predetermined connection state is not easily released.

When it is desired to maintain the above-mentioned connection state permanently, for example, as shown by a virtual diagram in FIG.
A seating nut 52 may be screwed onto the distal end portion 51a of the insertion body 51, or a retaining structure (not shown) such as inserting a retaining pin into the distal end portion 51a of the insertion body 51 may be provided. Of course.

In this embodiment, as shown in FIG. 3, the connecting member 6 is a hook 61 formed in an inverted U shape, and the hook 61 is set to be long. Base end portion 61a inserted into cylindrical body 41 as holder member 4
And a short end portion 61b.

The base 61a and the tip 61b are connected by a connection 61c.

In this embodiment, it is assumed that the tip 61b of the hook 61 is connected to the receiving member 7 provided on the support column 11 forming the other support 1.

That is, the hook body 61 has a base end 61a.
Is inserted into the cylindrical body 41 as the holder member 4,
When the distal end portion 61b is connected to the receiving member 7 provided on the support column 11, a predetermined connection state appears, and when the distal end portion 61b is separated from the receiving member 7 provided on the support column 11, it is connected. Is set to be released.

In this embodiment, the receiving member 7 is a cylindrical body 71 formed in the same shape as the cylindrical body 41 as the holder member 4. It is said that it will be integrally connected by the use of.

When the tapping screw 72 is screwed in, a through-hole 71a which is vertically opened in a so-called side portion of the cylindrical body 71 is used.

Therefore, the connection between the holder member 4 and the receiving member 7 by the connecting member 6 is performed in a state where the base end portion 61a of the hook member 61 is inserted into the cylindrical member 41 as the holder member 4 in the illustrated example. In this case, it is sufficient if the distal end portion 61b of the hook 61 is inserted into the cylindrical body 71 serving as the receiving member 7 (the state shown in FIG. 3).

In this case, the hook 61 is attached to the base 6
1a is lengthened and the distal end 61b is shortened, so that the connecting portion 61c of the hook 61 is slightly lifted, for example, by grasping it with a finger, so that the distal end 61b becomes
1 or can be extracted from the cylindrical body 71.

In this embodiment, when the hook 61 is made of a steel material or the like and its weight is relatively large, the hook 61 is always maintained in a downward tendency. This is advantageous in that the above-described predetermined linked state can be continuously maintained unless a positive operation is performed.

When it is desired to maintain the above-mentioned connection state permanently, or to prevent the escape due to vibration or the like, for example, as shown by a phantom diagram in FIG. Assuming that a spring 63 whose end is locked by a seat nut 62 is interposed at a portion of the end 61a exposed below the cylindrical body 41, a return structure for urging the hook 61 in a downward tendency is provided. Of course, it is good.

In this case, since the hook 61 is normally held by the holder member 4, troubles such as the hook 61 being lost during transportation of the door body 2 can be avoided in advance. Is also advantageous.

The temporary gate according to this embodiment formed as described above is, of course, suitable for use as an entrance / exit gate in a temporary enclosure at a construction site or the like, as well as a pair of opposing support portions 1 and 1. Since it has an integral door body 2 in between, it is particularly suitable for use as a landing gate on a temporary scaffold at a construction site.

In this case, since the door body 2 is made of aluminum, the weight can be reduced as compared with the case where it is made of steel, and the total weight of the temporary gate having the door body 2 can be reduced. Can be reduced.

Further, since the door body 2 has the same configuration at both ends, there is no direction to determine the front and back. Therefore, the door body 2 is placed between the pair of support portions 1, 1 facing each other. Can be arranged without distinction.

Then, while one end of the door body 2 which is formed to be extendable is fixedly connected to one of the support portions 1, the other end is separated from the other support portion 1. By being linked, the temporary gate is opened by an opening operation to bring the other end of the door body 2 closer to the one end,
Conversely, the temporary gate can be closed by a closing operation that separates the other end of the door main body 2 from the one end.

When the door body 2 is opened and closed, the caster 3 held at the lower end of the door body 2 rolls to smoothly expand and contract the door body 2, that is, the temporary gate is smoothly opened and closed. Will be.

FIG. 4 shows a temporary gate according to another embodiment of the present invention. In this embodiment, a plurality of door bodies 2 are arranged in series between a pair of opposed support portions 1, 1. In the illustrated example, two doors are provided, and the door main body 2 is set so as to exhibit a so-called double sliding door form.

In this embodiment, the structures of the support portion 1 and the door body 2, and furthermore, the structures of the holder member 4, the locking member 5 and the connecting member 6 are the same as those of the above-described embodiment.
Unless necessary, the same parts in the configuration are given the same reference numerals in the drawings, and detailed description thereof is omitted.

In the case of this embodiment, the door body 2
Are the frame members 2 at both ends, that is, the left and right ends in the figure.
2 is provided on the supporting portion 1 facing the support column 11,
Are connected under the interposition of

On the other hand, the central portion of the door bodies 2 connected in series is placed such that the frame bodies 22 of the adjacent door bodies 2 face each other.
Are linked by a linking body 6.

Therefore, in this embodiment, unlike the above-described embodiment, the supporting column 11 as the supporting portion 1 erected on the left and right has the insertion member 51 as the locking member 5. This is advantageous in that the number of members can be reduced in forming the support portion 1.

In this embodiment, the linking members 6 are linked at the center of the door bodies 2 connected in series to the holder members 4 disposed on the respective frame members 22. become.

Therefore, in the case of this embodiment, a temporary gate can be provided at the opening of a so-called wide frontage, which is most suitable for use as an entrance gate in a temporary enclosure such as a construction site.

Although not shown, in this embodiment, since the overall length of the door body 2 in the horizontal direction is increased, an appropriate bar structure may be provided as a so-called fall-prevention. In order to prevent the central portion of the door body 2 from moving, an appropriate lock structure may be provided between the door body 2 and the ground surface or the like.

In the above-described embodiment, the holder member 4
Consists of a tubular body 41 opening up and down, the locking body 5 consists of an insertion body 51 formed in the shape of an L-shaped hook, and the connecting body 6 consists of a hook body 61 formed in an inverted U-shape. Further, it is assumed that the receiving member 7 is formed of a cylindrical body 71 that is opened at the top and bottom. However, as long as a predetermined connection state and a connection state are realized, other arbitrary forms may be selected instead of the above-described embodiments. Of course, it may be done.

In each of the above-described embodiments, the frame body 22 is preferably provided with a handle portion 27. By providing the handle portion 27, the door body 2 can be expanded and contracted, that is, The opening and closing operation of the temporary gate becomes easy.

When providing the handle portion 27,
In the case where the handle portion 27 is formed by a vertical hole formed in the frame body 22, an operation of lifting the frame body 22 through a hand through the vertical hole becomes possible, and the door for the support portion 1 described above can be operated. This brings about an advantage of facilitating the connection and release operations of the main body 2.

[0082]

As described above, according to the present invention, the door body constituting the temporary gate is formed of aluminum.
This makes it possible to reduce the weight of the door body as compared with the case where it is formed of a steel material, so that the work of transporting the door body and the work of arranging the door body at a predetermined position become easy.

Since the weight of the door body is reduced,
It is possible to reduce the total weight of the temporary gate having the door body, to facilitate handling such as transportation, to improve workability at the time of installation, and to improve access to an entrance gate in a temporary enclosure such as a construction site. Not only is it suitable for use, but also suitable for use as a landing gate in temporary scaffolds who do not like the burden of overweight.

Further, according to the present invention, since the door body is configured to have the same shape at both ends, there is no directionality to determine the front and back of the door body, so that the door body faces the door body. It is not necessary to determine the front and back of the arrangement between the pair of support portions, and the workability in the installation work of the temporary gate is improved.

Further, according to the present invention, since the door body is formed in the form of a telescopic door capable of expanding and contracting in the lateral direction, the size of the opening is limited within a range where the door body is maximally extended. Regardless, it can be installed.

Still further, according to the present invention, the door body is fixedly connected to the support portion by the locking member in the presence of the caster, and is connected to the support portion or the adjacent door body. The opening and closing operation of the door body can be quickly and easily performed by the connecting operation and the releasing operation by the connecting member.

As a result, according to the present invention, handling such as transportation is facilitated, workability at the time of installation is improved, and diversion thereof is enabled, so that a doorway at a temporary enclosure at a construction site or the like can be obtained. There is an advantage that it is most suitable for use as a landing gate in a gate or a temporary scaffold.
