Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a telescoping gate configured to be able to be opened and closed by expanding and contracting in the horizontal direction, and more specifically relates to a first link member and a second link member. A plurality of X-shaped link composite members are pivotally connected to each other in an X-shape, and each end of the composite member is pivotally connected, and a telescopic link mechanism configured in a pantograph structure that can be freely expanded and contracted in the horizontal direction is arranged above and below. In addition, the present invention relates to an improvement of a telescoping gate in which a gate structure is disposed between each upper and lower first link member and between each second link member.

(Prior Art) In the case of conventional telescopic gates of this type, each gate structure is constructed with a large number of vertical bars arranged in parallel in a facing manner, and the upper and lower ends of the plurality of vertical bars are connected to upper and lower link members. They are each attached separately by screwing means such as bolts or riveting means using bets.

(Problems to be Solved by the Invention) However, the work of attaching vertical bars by such screwing or riveting means is extremely troublesome, and moreover, the parts that require the work are only attached to one gate structure. Since there are a large number of gates, and the number of gates is extremely large in terms of the gate as a whole, the assembly of the gate as a whole becomes complicated, making it impossible to mass-produce gates efficiently, which in turn increases manufacturing costs. There was a problem that it was difficult to provide inexpensive gates.

In addition, in order to eliminate such problems as much as possible,
If the number of vertical bars constituting each gate structure is reduced, the distance between the vertical bars becomes wider than necessary, and the gate structure acts as a blindfold and serves as a fence to prevent dogs and cats from entering and exiting. There was a problem that the effect was not being effectively demonstrated.

By the way, in order to solve both of the above-mentioned problems, it is possible to make the link member short, but the length of this link member is determined to ensure the stability of the gate posture and the telescopic function of the telescopic link mechanism. In order to maintain this, it cannot be made shorter than necessary.

Therefore, it is important to efficiently mass-produce conventional retractable gates to reduce manufacturing costs, and to configure the gate components to provide sufficient protection as a blindfold or fence. These were contradictory demands, and it was impossible to satisfy both.

The present invention provides a telescoping gate that satisfies both of these contradictory demands.

(Means for solving the problem) That is, the telescopic gate of the present invention has
Between the link members and between the second link members, the first and second gate structures, each consisting of a pair of vertical bars and a plurality of horizontal bars fixed to the bridge vertically in parallel between the vertical bars, are placed horizontally to each other.

In addition, the second gate structure 2' connects each horizontal bar 12' to each horizontal bar 1 of the first gate structure 2, as shown in FIG.
Each horizontal bar 1 is placed in a cross-shaped manner between 2 and 12.

It has exactly the same structure as the above-described first gate structure 2, except that it is shifted upward by a predetermined amount. Therefore, common members will be illustrated using the same symbols with dashes, and their details will be omitted.

Next, the assembly procedure of the telescopic gate of this embodiment will be explained.

First, as shown in FIG. 10, the first gate structure 2
Assemble. That is, one end of each horizontal bar 12 is
The first to fourth notch grooves 3 for one vertical bar 11
-16 are positioned by engaging the first to fourth engaging parts 12d to 12g, and then the first and second crimping parts 12b, 12b and 12c, 12c are pressed with an appropriate press tool (not shown). ) and crimp it.
The first gate structure 2 is fixed to the crimped part 11b of one of the vertical bars 11, and by the same operation, the other end of each horizontal bar 12 is fixed to the crimped part 12b of the other vertical bar 11. Assemble.

Next, the second gate structure 2' is assembled by the same operation as described above, but in this case, as shown in FIG.
1', each horizontal bar 1' is fixed to the crimped part 11'b
With the other end side of 2' being inserted between each of the horizontal bars 12, 12 of the first gate structure 2, each horizontal bar 12'
The other end portion is fixed to the crimped portion 11'b of the other vertical bar 11'.

In this way, a required plurality of sets of the first and second gate structures 2, 2', which are formed into one unit with the horizontal bars 12, 12', intersecting with each other, are assembled.

Then, X-shaped link composite members 3, 3' are fixed to the upper and lower ends of the first and second gate structures 2, 2', respectively. That is, each vertical bar 1,1
1' are connected to the upper and lower link members 3a,
3'a and 3b, 3b', the vertical bar insertion holes 10a,
10'a, 10b, and 10'b, and screw the setscrews 17 to fix them. In this case, the X-shaped link composite members 3, 3' formed by pivoting the first link members 3a, 3'a and the second link members 3b, 3'b at the center are assembled in advance.
In other words, the first and second link members 3a, 3'a and 3b, 3'b may be pivotally connected and then attached to the first and second gate structures 2, 2' units, or The assembly may be performed after each link member 3a, 3'a, 3b, 3'b is attached to the first and second gate structures 2, 2' units.

Further, the first and second gate structures 2, to which the X-shaped link composite members 3, 3' are attached in this way,
After obtaining a plurality of 2' units as shown in FIG.
a, 8b and 8'a, 8'b are pivotally connected via each support shaft member 9.

For the telescopic gate configured as above,

7. Each gate structure 2,
2' can be attached. Moreover, each gate structure 2, 2' can be efficiently assembled by caulking work that can be performed easily and quickly regardless of the number of horizontal bars 12, 12', . Therefore, compared to the conventional method in which each gate structure is assembled by separately fixing a large number of vertical bars to each upper and lower link member by screwing or riveting means,
The entire gate can be easily assembled, the gate can be mass-produced efficiently, and the manufacturing cost can be reduced to provide an inexpensive gate.

Furthermore, since such an advantage is not lost depending on the number of horizontal bars 12..., 12'... as described above, it is possible to increase the number of horizontal bars 12..., 12'... By reducing the distance between the crosspieces, the above-mentioned advantages can be maintained while the first and second gate structures 2, 2' are sufficiently effective in providing protection as a blindfold and a fence.

Moreover, the horizontal bars 12 of the first gate structure 2 and the second
Since the horizontal bars 12' of the gate structure 2' intersect with each other, the design effect as a gate is very excellent, and the commercial value of the gate can be improved.

In addition, the end of each horizontal bar 12, 12' is connected to each vertical bar 1.
The first to fourth engaging portions 12d of each horizontal bar 12, 12' are formed in the first to fourth notch grooves 13 to 16, 13' to 16' formed in the crimped portions 11b and 11'b of 1 and 11'. ~1
2g, 12'd to 12'g are engaged with each other, and each vertical bar 11, 11' is positioned and temporarily fixed to each vertical bar 11, 11'. The gate structures 2, 2' can be assembled more easily and accurately. In addition, especially since the first and fourth engaging parts 12d and 12g are located between the first and second crimp parts 12b and 12b and 12c and 12c, the first and second crimp parts 12b and 12b
And when 12c and 12c are caulked, the first and fourth
Some of the engaging parts 12d and 12g are shown in FIGS. 4 and 5.
As shown in the figure, the first and fourth notch grooves 13 and 16 are bulged into the expanded groove portions 13a and 16a through plastic deformation, and as a result, the vertical bar 11 and the horizontal bar 12 This makes it possible to improve the rigidity and durability of the first gate structure 2 (the same applies to the second gate structure 2'), which in turn improves the durability and operability of the gate. can be improved.

Furthermore, the first and second link members 3a, 3'a
and 3b, 3'b, hinge members 8a, 8'b, 8b,
8'b, vertical bars 11, 11' and horizontal bars 12, 12',
Since each of these is a common member obtained by drawing an aluminum material into a pipe and cutting it into a predetermined length, it is extremely advantageous in terms of manufacturing cost of the constituent members of the gate.

Note that the telescoping gate according to the present invention is not limited to the above embodiments.

For example, in the embodiment, the horizontal bars 12 of the first gate structure 2 and the horizontal bars 1 of the second gate structure 2'
2'... were made to intersect with each other, but
The former horizontal bars 12... and the latter horizontal bars 12' may be divided into one or more groups, and each group may be made to intersect with each other.

Furthermore, each crimped portion 11b, 11'b is not formed into a series of elongated pieces extending over the upper and lower ends of each vertical bar 11, 11' as in the previous embodiment, but instead
It may be arranged intermittently only at the locations where the ends of 2 and 12' are attached. Further, in the embodiment, each crimp portion 12b, 12'b, 12,
12'c is provided in a protruding shape, and each crimping part is for caulking and fixing the ends of the horizontal bars 12, 12' to the crimped parts 11b, 11'b of the vertical bars 11, 11'. Therefore, it is sufficient to provide at least the ends of the horizontal bars 12, 12'. However, the crimped parts 11b, 11'b and the crimped parts 12b, 12'b,
If 12c and 12'c are made to extend across both ends of the vertical bars 11, 11' and the horizontal bars 12, 12', respectively, the vertical bars 11, 11' and the horizontal bars 12, 12' can be used to draw the workpiece. There are manufacturing advantages that can be obtained by cutting. The same applies to each of the engaging portions 12d to 12g and 12'd to 12'g.

(Effects of the Invention) As can be easily understood from the above explanation, the extendable gate of the present invention has a gate structure in which a plurality of horizontal bars are fixed to a bridge in a vertically parallel manner to a pair of vertical bars. , it can be assembled as a separate unit from the telescoping link mechanism and by attaching a pair of vertical bars in this unit to the upper and lower link members, so compared to conventional ones,
The entire gate can be assembled easily, mass production can be carried out efficiently, and the manufacturing cost can be reduced, so that it can be provided at low cost.

Moreover, since the horizontal bars of the first gate component and the horizontal bars of the second gate component cross each other, there is no need to increase the number of horizontal bars in one gate component more than necessary, and the horizontal bars can be easily removed from the entire gate. For example, it becomes possible to reduce the distance between the horizontal bars. Therefore, without hindering the ease and speed of assembling each gate component as a unit, the above-mentioned advantages can be maintained, and the desired blindfolding effect and protective effect as a fence can be achieved by the telescopic gate. It can be configured in such a way that it can be used.

Furthermore, since the horizontal bars of the first gate structure and the horizontal bars of the second gate structure are configured to intersect and the crossing angle changes as the gate is opened and closed, conventionally It exhibits a novel design effect that has never existed before, and has an extremely high commercial value.

In particular, if the end of each horizontal bar in each gate structure is fixed to the vertical bar by caulking means, the horizontal bar can be fixed to the vertical bar by screwing means such as bolts or riveting means such as rivets. Compared to the case where they are fixed together, each gate structure can be assembled more easily and efficiently, and the production efficiency of the gate as a whole can be greatly improved.
