Description

Technical Field

[0001] The utility model relates to a practical sliding gate, and more particularly, the utility model especially relates to a sliding gate with an electric function. Background Art

[0002] Sliding gates, especially those for outdoor use, are commonly known as electric sliding gates. With the improvement of people's living standards and the rise of outdoor sports, this product is now widely known and increasingly popular.

[0003] Generally, an electric sliding gate includes a frame, a barrier in the form of a plate or other similar element, ground running wheels, and guiding devices for these wheels, such as tracks and at least one support column; generally, a driving device for the barrier, such as a pinion rack system, is defined on the column, where the pinion is fixed to the lower part of the barrier and the pinion is driven by an electric gear motor.

[0004] Although this type of sliding gate is popular and widespread, there are some aspects that can be improved.

[0005] The first disadvantage associated with sliding gates is that there must be a support column located at one end of the opening where the sliding gate is installed; this support column is typically configured to support the movable barrier in a stable vertical position at any time during the movement of the movable barrier.

[0006] The support column typically includes a set of idler wheels that pivot about a vertical axis and are positioned such that one or more of the idler wheels abut against a first vertical surface of the movable barrier and such that one or more of the idler wheels abut against a second opposite vertical surface of the same movable barrier, and the movable barrier is arranged to run between these idler wheels.

[0007] The assembly defined by the support column and the idler wheels accompanying the movable barrier is typically bulky and has little visual impact; in particular, the construction of this set of support wheels requires a certain number of components and a certain assembly time, and the corresponding cost is also very high.

[0008] The second disadvantage of this support device for the movable barrier is that if, due to any type of damage or malfunction, the movable barrier moves outside the support wheel group, the movable barrier will fall to the ground, which poses a very serious danger to anyone who may be near the movable barrier. Summary of the Invention

[0009] The object of the utility model is to develop a sliding gate that can eliminate the above disadvantages and limitations of the prior art.

[0010] Specifically, the object of the utility model is to develop a sliding gate that is safer than similar electric sliding gates of known types.

[0011] Another object of the present utility model is to develop a sliding gate that is smaller in volume than known types of electric sliding gates.

[0012] A further object of the present utility model is to develop a sliding gate that is easier to install than known similar gates.

[0013] The above tasks and objects are achieved by the following technical solutions.

[0014] A sliding gate, comprising:

[0015] A movable barrier;

[0016] One or more running wheels, which are pivoted to the movable barrier relative to a normal operating device and project downward from the movable barrier;

[0017] Guide rails that define a running surface for the one or more running wheels and define a running direction for the movable barrier;

[0018] An anti-overturning device configured to slidably couple the movable barrier to the guide rails; characterized in that:

[0019] The anti-overturning device includes two oppositely arranged rolling members, each rolling member being supported by a bracket that extends downward from the bottom of the movable barrier; and

[0020] The bottom of the movable barrier includes a bottom plate that is defined at a receiving portion defined in the lower part of the movable barrier.

[0021] For the sliding gate according to the present utility model, the cross-section of the guide rail is T-shaped. The guide rail includes a lower part for connecting to the ground and an upper part for supporting the running wheels, and the cross-sectional width of the upper part is greater than the cross-sectional width of the lower part.

[0022] For the sliding gate according to the present utility model, the rolling member is spherical, including a ball pushed outward by an elastic element contained in the body of the rolling member. Wherein, the ball is freely rotatably held in a housing having an opening, and the size of the opening allows the ball itself to project therefrom.

[0023] For the sliding gate according to the present utility model, the rolling member is of the bearing type, including a bearing pivoted to a pin supported by a support fork, and the support fork is pushed toward the guide rail by an elastic element contained in the body of the rolling member.

[0024] For the sliding gate according to the present utility model, it is characterized in that the bracket extends downward from the bottom plate, and the rolling member is configured such that the anti-overturning device slides.

[0025] The sliding gate according to the present utility model is characterized in that each of the rolling members in the rolling members extends from the corresponding bracket until the rolling member contacts the guide rail below the upper part of the guide rail.

[0026] For the sliding gate according to the present utility model, the anti-overturning device includes two pairs of opposite rolling members.

[0027] For the sliding gate according to the present utility model, the first pair of rolling members is located near the first running wheel, while the second pair of rolling members is located near the second running wheel.

[0028] The present utility model also discloses an anti-overturning device for a movable barrier of a sliding gate, which includes a bottom plate having an anti-overturning device on the plate. The anti-overturning device is configured to slidably couple the movable barrier to the guide rail. The guide rail has a T-shaped cross-section and includes a lower part for connecting to the ground and an upper part for supporting the running wheels. The cross-sectional width of the upper part is greater than the cross-sectional width of the lower part. The anti-overturning device includes two opposite rolling members, and each rolling member is supported by a corresponding bracket extending downward from the bottom plate. Each of the rolling members in the rolling members extends from the corresponding bracket until the rolling member contacts the guide rail below the upper part of the guide rail.

[0029] The sliding gate disclosed by the present utility model is safer than similar sliding gates of known types because the anti-overturning device prevents the movable barrier from falling in a direction transverse to the forward direction X at any time; therefore, the movable barrier does not need to be supported by support columns and a set of idler wheels.

[0030] In addition, the sliding gate disclosed by the present utility model is smaller in volume than known sliding gates because the sliding gate does not have support columns.

[0031] In addition, the sliding gate of the present utility model is easier to install than similar known gates because the sliding gate does not need to install support columns with a corresponding set of idler wheels necessary for supporting the movable barrier. Description of the Drawings

[0039] Referring to the accompanying drawings cited, the sliding gate according to the present utility model is generally designated by the numeral 10.

[0040] Such a sliding gate 10 includes:

[0041] A movable barrier 11;

[0042] One or more running wheels, for example, two running wheels 12 and 13, which are pivotally attached to the movable barrier 11 with respect to a normal operating device and project downward from the movable barrier;

[0043] A guide rail 28; such a guide rail 28 defines a running surface for one or more running wheels 12, 13 and defines the running direction X of the movable barrier 11.

[0044] The sliding gate 10 is characterized in that the sliding gate includes an anti-overturning device 30 which is configured to slidably couple the movable barrier 11 to the guide rail 28.

[0045] In the embodiment of the present utility model shown herein, by way of non-limiting example of the present utility model itself, the guide rail 28 has a T-shaped cross-section.

[0046] Specifically, such a guide rail 28 includes a lower part 28b for connection to the ground and an upper part 28a for supporting the running wheels 12, 13. The cross-sectional width of the upper part 28a is greater than the cross-sectional width of the lower part 28b; such a configuration results in the cross-section of the guide rail 28 being the aforementioned T-shaped.

[0047] Specifically, and preferably, the anti-overturning device 30 includes two opposing rollers 31, each roller being supported by a respective bracket 32 extending downward from the bottom of the movable barrier 11.

[0048] For example, the bottom of the movable barrier 11 includes a bottom plate 25a.

[0049] The bottom plate 25a is defined at a receiving portion 25 defined in the lower part 11a of the movable barrier 11.

[0050] The bracket 32 extends downward from the bottom plate 25a.

[0051] In the first embodiment of the present utility model, each rolling member 31 is spherical.

[0052] As Figure 4 shown, the spherical rolling member 31 includes a ball 31a pushed outward by an elastic element 31b contained in the main body 31c of the spherical rolling member 31, wherein the ball 31a is rotatably held in a housing having an opening 31d, and the size of the opening allows the ball 31a to protrude therefrom.

[0053] The spherical rolling member 31 has, for example, a main body 31c having an external thread, for example, a flat head screw.

[0054] The main body 31c is inserted into a through hole 32a defined in the bracket 32 and fixed to the bracket 32 itself by two opposite nuts 32c.

[0055] Thus, in the case of wear or breakage, each rolling member 31 can be easily replaced.

[0056] The rolling member 31 is configured such that the anti-overturning device 30 operates without rubbing against the guide rail 28.

[0057] Each of the rolling members 31 extends from the corresponding bracket 32 until the rolling member contacts the guide rail 28 below the upper part 28a of the guide rail 28, that is, contacts the lower part 28b of the guide rail 28 itself. Preferably, as Figure 2 , 3 , 5 and 6 show, the anti-overturning device 30 includes two pairs of opposite rolling members 31.

[0058] Still preferably but not exclusively, the first pair of rolling members 31 is located near the first running wheel 12, while the second pair of rolling members 31 is located near the second running wheel 13.

[0059] The rolling member 31 allows the anti-overturning device 30 to operate without rubbing against the guide rail 28.

[0060] In Figure 5 the alternative embodiment shown, the sliding gate 10 includes:

[0061] a movable barrier 11;

[0062] one or more running wheels, for example, two running wheels 12 and 13, which are pivotally connected to the movable barrier 11 with respect to the normal operating device and protrude downward from the movable barrier;

[0063] a guide rail 28; such a guide rail 28 defines a running surface for one or more running wheels 12, 13 and defines the running direction X of the movable barrier 11;

[0064] The anti-overturning device 130 is configured to slidably couple the movable barrier 11 to the guide rail 28.

[0065] In particular, and preferably, the anti-overturning device 30 includes two opposite rolling members 131, each rolling member being supported by a respective bracket 32 extending downward from the bottom of the movable barrier 11.

[0066] For example, the bottom of the movable barrier 11 includes a bottom plate 25a.

[0067] The bottom plate 25a is defined at a receiving portion 25 defined in the lower portion 11a of the movable barrier 11.

[0068] In the second embodiment of the present utility model, each rolling member 131 is of a bearing type.

[0069] As Figure 6 clearly shown, the rolling machine 131 of the bearing type includes a bearing 131a.

[0070] Similar to the description of the spherical rolling machine 31 above, the bearing 131a pivots to a pin supported by a support fork 131f, and the support fork is in turn pushed against the guide rail 28 by an elastic element contained in the body 131c of the rolling member 131.

[0071] The bearing 131a is intended to be a ball bearing, a roller bearing, and other similar and equivalent types of bearings.

[0072] Alternatively, the rolling machine 31 includes a simple wheel or a simple roller instead of a bearing.

[0073] The sliding gate 10 may include two running wheels 12 and 13, namely a first front running wheel 12 and a second rear running wheel 13, and the running wheels 12, 13 are disposed within the lower portion 11a of the movable barrier 11.

[0074] The presence of the two running wheels 12 and 13 positioned as described above allows the movable barrier 11 to support itself in a balanced manner, that is, to prevent the movable barrier 11 from tilting forward or backward with respect to the forward direction X.

[0075] The bottom plate 25a of the receiving portion 25 has windows 25c for each of the running wheels 12 and 13; these windows 25c are clearly visible in Figure 4 ...

[0076] As described above, the bottom plate 25a further includes brackets 32 for the rolling machines 31, two opposite first support bumps 33 for the first running wheel 12, and two opposite second support bumps 34 for the second running wheel 13.

[0077] An anti-overturning device or anti-overturning kit 50 for a barrier of a sliding gate is also the subject of the present utility model. The anti-overturning device or anti-overturning kit includes a bottom plate 25a which has anti-overturning devices 30, 130 on the plate.

[0078] As described above, the anti-overturning devices 30, 130 are configured to slidably couple the movable barrier 11 to the guide rail 28 which has a T-shaped cross-section.

[0079] The guide rail 28 includes a lower part 28b for connection to the ground and an upper part 28a for supporting the running wheels 12, 13, and the cross-sectional width of the upper part 28a is greater than the cross-sectional width of the lower part 28b.

[0080] The anti-overturning devices 30, 130 include two opposite rolling members 31, 131, each rolling member being supported by a corresponding bracket 32 extending downward from the bottom plate 25a, and each of the rolling members 31, 131 extends from the corresponding bracket 32 until the rolling member contacts the guide rail 28 below the upper part 28a of the guide rail 28.

[0081] Optionally, the anti-overturning device 50 further includes supporting wheels 12 and 13; such a device 50 can be easily installed on any barrier of the gate, even on an existing barrier, so as to form a particularly safe sliding gate.

[0082] The device 50 may include a guide rail 28 which is configured to be coupled to the anti-overturning device 30 which is in turn integrated onto the bottom plate 25a as described above.

[0083] It has been proved in practice that the present utility model has achieved the expected tasks and purposes.

[0084] In particular, the sliding gate disclosed by the present utility model is safer than similar sliding gates of known types, because the anti-overturning device prevents the movable barrier from falling in a direction transverse to the forward direction X at any time; therefore, the movable barrier does not need to be supported by support columns and a set of idler wheels.

[0085] In addition, the sliding gate disclosed by the present utility model is smaller in volume than known sliding gates, because the sliding gate does not have support columns.

[0086] In addition, the sliding gate of the present utility model is easier to install than similar known gates, because the sliding gate does not need to install support columns with a corresponding set of idler wheels necessary for supporting the movable barrier.

[0087] The utility model thus conceived admits of various modifications and variations, all of which are within the scope of the concept of the utility model; in addition, all details may be replaced by other technically equivalent elements. In practice, as long as the components and materials used, as well as the dimensions and shapes, are compatible with a particular use, they may be arbitrary according to requirements and the state of the prior art.

[0088] If reference signs follow features and technicalities mentioned in any claim, the sole purpose of these reference signs is to increase the intelligibility of the claim, and accordingly, these reference signs have no limiting effect on the interpretation of each element identified by way of example by these reference signs.
