Description

  The present invention relates to a stopper for a telescopic gate. More particularly, the present invention relates to a stopper that is used when the telescopic gate is closed in an telescopic gate that opens and closes the gate when the gate itself expands and contracts.

There exists a thing of patent document 1 as a conventional expansion-contraction gate.
The telescopic gate of Conventional Example 1 will be described with reference to FIGS.
The telescopic gate 103 extends and contracts in the opening and closing direction along the gate rail 104 laid on the ground between the two gate columns 101 and 102, and is housed in the original gate column 101 in the contracted state. The telescopic gate 103 includes vertical end frames 105 and 106 arranged at both ends in the opening and closing direction, a plurality of vertical frames 107 arranged at equal intervals in the opening and closing direction between the end frames 105 and 106, and each vertical frame 107 and a pantograph mechanism 108 that is extendable in the opening and closing direction for connecting the end frames 105 and 106.

  The end frame 105 on the side of the suspension gate pillar 101 is provided with a moving roller 112 so as to be rotatable, and the movement roller 112 rolls in an opening / closing direction along a support rail 113 arranged vertically in the suspension gate pillar 101. Thus, the suspension side end frame 105 moves in the direction of opening and closing within the suspension gate column 101. Stoppers 114a and 114b for restricting movement in the opening / closing direction are provided at both ends in the opening / closing direction of the support rail 113 in the suspension main pillar 101, respectively. For this reason, when the telescopic gate 103 is contracted and housed in the hanging main gate 101, the end frame 105 stops by hitting the stopper 114a on the back side, and when the telescopic gate 103 extends and extends to the door column 102, The end frame 105 hits the stopper 114b on the exit side so that it does not come out from the suspension gate pillar 101. In other words, the exit stopper 114b ensures that the gate opening is completely closed by the telescopic gate 103. Such a telescopic gate can be reduced in size by moving the suspension side of the gate by the length of the gate at the time of storage, so that the length when extended is the same as the opening width of the gate. The frontage can be effectively closed.

  In the above-mentioned conventional example 1, the rear and outlet stoppers 114a and 114b are attached in the suspension gate pillar 101, but there is a conventional example 2 in which the stoppers are installed on the ground in the suspension gate pillar 101 instead. It was. As shown in FIG. 9, in this conventional example 2, a rectangular base 201 is installed between two gate rails 104 installed on the ground, and the base 201 is made up of two plates on the left and right sides. Are spaced apart. A rear stopper 204a is attached to the rear end of the base 201, and an outlet stopper 204b is attached to the tip. Several types of bases 201 having different lengths are prepared. This is because there are several types of telescopic gates that have different lengths depending on the gate entrance, and the length of the gate when contracted differs accordingly.

  The base body 201 in the stopper structure is fixed with mortar between the two gate rails 104. Since both the back stopper 204a and the outlet stopper 204b are fixed to both ends of the base body 201, the distance between the stoppers is naturally in accordance with the length of the base body 201, but the distance cannot be changed. It is fixed.

The conventional examples 1 and 2 have the following problems.
In the prior art example 1, if the two stoppers 114a and 114b are installed on site, the workability deteriorates. For this reason, the conventional example 1 is also standardized in terms of dimensions, and several types of units are prepared in advance. In this case, it is constructed as a unit similar to Conventional Example 2.
However, in the conventional units 1 and 2 that are unitized, it is necessary to prepare stopper units with different lengths according to the contraction widths of gates with different sizes, so that there is a problem that parts management is troublesome and the stock quantity increases. is there.

  In the conventional examples 1 and 2, when the telescopic gate 103 is extended and stopped by the exit stoppers 114b and 204b (the gate is closed), the contraction width of the gate and the stopper position may not completely match. As a result, the telescopic gate may not be fully extended or may be extended forcibly. If it is not fully extended, play (backlash) will occur in the extension direction of the telescopic gate, the vertical frame spacing will not be uniform, the appearance will be poor, and the product quality itself will be inferior It gave a good impression. On the other hand, if it is extended forcibly, the gate will be forcibly extended when closing, and the smooth closing operation will not be possible, and excessive force will be applied to the gate member, reducing the durability. It occurred.

JP 2002-194777 A

  In view of the above circumstances, an object of the present invention is to provide a stopper for a telescopic gate that can be used regardless of the size of the telescopic gate and does not apply an excessive force to the gate member or cause incomplete extension.

The stopper of the telescopic gate according to the first aspect of the present invention is the telescopic gate that travels in the open / close direction on the gate rail installed between the suspension stopper and the door support side column, and when the suspension-side end of the telescopic gate is opened / closed A stopper that regulates a moving distance, a stop bracket, a base provided at a plurality of locations along the traveling direction of the telescopic gate, and a base rail provided to the gate rail with respect to the gate rail. It is characterized by comprising an installation fitting attached at an arbitrary position in the longitudinal direction.
The stopper of the telescopic gate according to the second aspect of the present invention is the stopper according to the first aspect, wherein the base has a rectangular shape, and installation fittings are attached to the front and rear ends of the base, respectively. Contact surface portions that are in contact with the side surfaces of the gate rail are respectively formed, and a pressing bolt that presses against the gate rail is screwed into one of the contact surface portions.
The stopper of the telescopic gate of the third invention is the stopper according to the second invention, wherein the base is made of a pair of left and right plates, each plate is made of an upper horizontal plate portion, a vertical plate portion and a lower horizontal plate portion. The upper horizontal plate portions of the upper horizontal plate portions are opposed to each other and spaced from each other, and are attached to the installation metal fittings at intervals, and the upper horizontal plate portions are provided with holes for bolting the stop metal fittings along the longitudinal direction thereof. It is characterized by having multiple places.

According to the first invention, since the base of the stopper can be installed at an arbitrary position in the longitudinal direction of the gate rail by the installation bracket, the stopper having the same specification can be used regardless of the size of the telescopic gate. For this reason, parts management becomes easy and construction becomes easy. In addition, by selecting the installation position of the base with respect to the gate rail and selecting the optimal position from among multiple locations for mounting the stop bracket to the base, the telescopic gate can be extended and extended without difficulty. The extension of the gate can be adjusted.
According to the second invention, the two installation fittings can be installed substantially at right angles to the gate rail when the contact surface portions at both ends are along the two gate rails. Then, when the pressing bolt on one end side is screwed to the gate rail side, the contact surface portion on the other end side comes into close contact with the side surface of the gate rail. In this way, when the two adhesive surface portions of the two installation brackets are in close contact with the side surface of the gate rail, the installation bracket is accurately perpendicular to the gate rail, so that the base can be accurately positioned with respect to the gate rail.
According to the third invention, a space is generated between the left and right upper horizontal plate portions constituting the base body, and the stop bracket is attached so as to cross the space. Distributed. For this reason, it is hard to produce the position shift of a stopper by the collision of a telescopic gate. Further, since the pair of left and right plate members are coupled to each other by the stop fitting, the rigidity is increased.

Next, an embodiment of the present invention will be described with reference to the drawings.
In FIGS. 5 and 6, A is a telescopic gate to which the present invention is applied. A door stop frame 1 and a suspension frame 2 are provided at both ends, and a plurality of vertical frames 3 are erected between them. Are connected to each other by a pantograph 4. A roller 5 is rotatably supported at the lower ends of the door stop frame 1, the suspension frame 2, and an appropriate number of vertical frames 3, and runs on a gate rail 6 installed on the ground. These structures are publicly known, and the telescopic gate A can be expanded and contracted by the pantograph 4 so that the gate can be opened and closed.

Reference numeral 7 on the left side in the figure is a door-to-door support column, which is fixed to the ground. The door stop frame 1 of the telescopic gate A can be locked by a built-in lock.
The symbol B on the right side in the figure is a stopper according to the present invention. A suspension stopper 8 is provided at the end of the rail 6. This suspension stopper 8 is for restricting the stop position by the suspension frame 2 when the telescopic gate A is opened.

Next, the stopper B will be described with reference to FIGS.
In FIG. 1 and FIG. 2, 10 is a base | substrate and consists of a pair of left and right plate materials 11 and 11. Each plate member 11 includes an upper horizontal plate portion 12, a vertical plate portion 13, and a lower horizontal plate portion 14, which are formed by bending a single metal plate. Note that two or three metal plates may be joined by welding or the like.
The left and right plate members 11 and 11 are arranged with the upper horizontal plate portions 12 and 12 facing each other and spaced apart from each other.

Bolt holes 15 are drilled in the left and right upper horizontal plate portions 12 and 12 of the base body 10 at equal intervals along the longitudinal direction. In the illustrated embodiment, there are four bolt holes 15, but there may be two or three locations, or five or more locations.
The stop fitting 31 can be fixed to the bolt hole 15 with a bolt. The stop fitting 31 is a rod-like fitting and is a member having a length that is passed over the two upper horizontal plate portions 12 and 12 facing each other. When this stop fitting 31 is fixed to an arbitrary bolt hole 15 with a bolt, as shown in FIG. 2, the upper portions of the left and right plate members 11 and 11 are closed to form a gate shape in a sectional view. Reference sign G indicates the ground.

  As shown in FIG. 1, the base 10 has a rectangular shape in plan view, and mounting brackets 21 and 22 are attached to both front and rear ends thereof. Specifically, both end portions of the lower horizontal plate portions 14 and 14 of the plate member 11 are fixed to the central portions of the installation fittings 21 and 22 with bolts or the like. The installation fittings 21 and 22 are bar-shaped and extend at right angles to the longitudinal direction of the base body 10. Therefore, the base 10 and the two installation fittings 21 and 22 are substantially H-shaped in plan view.

  As shown in FIG. 4, the installation fittings 21 and 22 are elongated metal plates, and contact surface portions 23 and 24 are formed at both ends thereof. Each contact surface portion includes a standing wall 25 rising from the main body and a horizontal piece 26 extending horizontally outward from the upper end of the standing wall 25. A pressing bolt 28 is screwed into the standing wall 25 of the one contact surface portion 23. The other contact surface portion 24 is not provided with a pressing bolt.

Next, a method for installing the stopper B having the above structure will be described.
Since the stopper B of the present invention is directly attached to the two gate rails 6 and 6, the structure of the gate rail will be described with reference to FIG.
The gate rail 6 includes a central bottom surface 61, an inclined surface 62 that rises obliquely upward from one side of the central bottom surface 61, a parting edge 63 that protrudes from the upper end of the inclined surface, and a vertical surface 64 that rises from the other side of the central bottom surface 61. An engaged surface 65 that engages with an engagement fitting bent inward from the upper end of the upright surface 64, and a roller running surface 67 on which the gate roller rolls horizontally and outwards from the engaged surface 65 are provided. ing.

  1 and 4 show a state where the mounting is completed. At the beginning of mounting, the mounting brackets 21 and 22 are arranged so as to be substantially perpendicular to the two gate rails 6 and 6, and the contact surface portions 23, 24 is placed so as to be substantially parallel to the side surfaces of the gate rails 6 and 6. At this time, both contact surface portions 23 and 24 fit inside the gate rail 6, face the side surface (elevation surface 64), and the horizontal pieces 26 and 26 rest on the engaged surface 65 of the gate rail 6. .

  Next, when the pressing bolt 28 on one end side of the two installation fittings 21 and 22 shown in FIG. 4 is screwed, the standing wall 25 of the contact surface portion 24 on the other end side comes into close contact with the side surface (elevation surface 64) of the gate rail 6. Therefore, the two installation fittings 21 and 22 are both attached to the gate rails 6 and 6 while maintaining a right angle. Further, when the screwing force of the pressing bolt 28 is appropriately increased, the two installation brackets 21 and 22 are stretched in the two gate rails 6 and 6 and are firmly fixed. Furthermore, the lower part of the base body 10 and the mounting brackets 21 and 22 are buried with mortar together with the gate rail 6 and are firmly fixed.

  In the state in which the installation fittings 21 and 22 are fixed in this manner, the longitudinal direction of the base 10 is parallel to the gate rail 6 as shown in FIG. Accordingly, the gap between the two plate members 11 and 11 is naturally parallel to the gate rail 6, and no deviation occurs with respect to the traveling direction of the telescopic gate A traveling on the gate rail 6.

The stopper B can be attached to the gate rails 6 and 6 in the above-described manner at any position in the longitudinal direction of the gate rail 6, and any position can be selected continuously.
Furthermore, the attachment position of the stop fitting 31 to the base body 10 can be arbitrarily selected from a plurality of locations in the longitudinal direction (four locations in the present embodiment). For this reason, the stop position of the suspension side of the telescopic gate A can be freely selected.

FIG. 3 shows stop positions I and II when the telescopic gate A is stored and pulled out (when the gate is closed). In the figure, reference numeral 33 denotes an end frame fixed to the suspension base frame 2, and a fastener 32 is fixed to the lower end thereof. When the telescopic gate A is stored, the end frame 33 hits the suspension stopper 8 made of cushion rubber provided at the end of the gate rail 6 and stops. When the telescopic gate A is pulled out, the clasp 32 enters the central gap of the base 10 and moves. And in the state which pulled out the door stop frame 1 completely, the fastener 32 hits the stop fitting 31 attached to the base | substrate 10, and stops.
At this time, the door-holding frame 1 is locked to the door-holding column with a lock, the suspension frame 2 is stopped by the stop fitting 31, and the telescopic gate A is extended with a tensile force if appropriate. In this state, the gate is closed.

  As shown in FIG. 4, when the fastener 32 enters the central gap g of the base body 10, the gap g is parallel to the gate rail 6, so that the fastener 32 contacts the left and right plate members 11, 11. Such inconvenience can be avoided.

  Further, when the fastener 32 hits the stop fitting 31, the force is evenly distributed to the left and right plate members 11 and 11, and is also equally distributed to the two installation brackets 21 and 22 in the lateral direction. As described above, since the force is not concentrated, the positional deviation of the stopper B hardly occurs. In addition, since the pair of left and right plate members 11 and 11 are coupled to each other by the stop fitting 31, the base 10 itself has high rigidity, and therefore can be formed of a thin metal plate.

  As described above, in the present embodiment, the stop position on the suspension side of the telescopic gate A can be freely selected. That is, when the extended gate is excessively tensioned, the attachment position of the stop fitting can be changed to the door stop side, and when the telescopic gate A is closed, the gate can be closed without forcibly extending. In addition, if the gate length is excessive and the spacing between the vertical frames 3 and 3 varies, the mounting position of the stop bracket can be changed to the suspension side, and the gate can be extended to an appropriate length. . In other words, the gate can be closed in a state where the gate is extended to an appropriate length, the quality of each part of the telescopic gate A can be extended, and a beautiful aesthetic sense that the vertical frames 3 and 3 are evenly spaced can be exhibited. .
