This specification relates to safety gates that bridge between passageways, and in particular, to a safety gate with a foldable frame to transition to a storage/travel configuration.
Safety gates, commonly referred to as baby gates, bridge between passageways to keep children and pets contained within a specific area, or to keep children and pets from entering certain areas as the case may be. So-called “portable” baby gates can include a mechanism that reduces the overall footprint of the same for purposes of storage/travel. However, such portable baby gates tend to require a significant amount of storage space even when in the storage/collapsed configuration. Moreover, such baby gates often remain extended during travel/storage as the amount of time and user frustration to collapse and re-deploy a baby gate often outweighs the benefits of fully collapsing the same.
These and other features advantages will be better understood by reading the following detailed description, taken together with the drawings wherein:
Existing baby gates remain challenging to store and travel with in general. Baby gates that are marketed as “portable” often include limited storage/travel features. For instance, some gates provide the ability to collapse/retract to a minimum passageway width, or are constructed from relatively light-weight material. However, such existing portable gates remain relatively awkward to carry/store, and moreover, remain incapable of being stored within space-constrained spaces such as backpacks, suitcases, and overhead bins on a plane.
Thus, the present disclosure is generally directed to a safety gate, also referred to herein as gate device or simply a gate, having a gate frame that can fold and collapse into a compact profile for purposes of storage and travel. In an embodiment, a gate consistent with the present disclosure includes a plurality of frame members coupled together via hinged couplers to provide a gate frame, and preferably, a rectangular gate frame. The hinged couplers preferably provide an in-use configuration whereby the frame members occupy substantially the same plane and form a picture-frame/rectangular shape. Preferably, a foldable material such as mesh at least partially surrounds each frame member and extends between the frame members to form a sidewall. The hinged couplers also preferably include at least a first hinged coupler configured to allow for out-of-plane rotation about a first axis to fold the frame members relative to each other in a clamshell fashion, and at least a second hinged coupler to allow for in-plane rotation about a second axis to collapse the gate frame. The hinged couplers therefore allow the gate frame 102 to transition into a storage configuration whereby the frame members rotate about two different rotational axis to ultimately extend substantially parallel relative to each other for ease of storage and travel.
Each of the frame members can have a rectangular profile, e.g., as shown in
The structure of each frame member of the gate frame 102 can include a hollow body to advantageously reduce overall weight, or can be solid depending on a desired configuration. As discussed below, having hollow frame members for the gate frame 102 also allows for having telescoping capabilities, whereby a frame member with a first diameter at least partially receives and surrounds an inner frame member with a second diameter that is smaller than the first diameter. Accordingly, the example gate 100 shown in
The gate 100 further includes optional adjustable pressure members 110, which may also be referred to herein as simply pressure members. The optional adjustable pressure members 110 preferably include a body in the form of a threaded screw/bolt and an adjustable head affixed to one end of the body. The optional adjustable pressure members 110 then engage a threaded opening in an associated hinged coupler.
As shown more clearly in
In an embodiment, the fabric sidewall 108 comprises natural or synthetic fabric materials such as cotton, vinyl, polyester, and preferably, materials naturally resistant or otherwise treated to prevent wrinkling, water absorption, and/or staining such as polyester, nylon, acrylic and olefin, or a combination thereof. In addition, the fabric sidewall 108 can include a mesh (e.g., as shown in
As further shown in
The fabric sidewall 108 can also include the aforementioned hook and loop sections, or other tensioning feature such a strap, to allow a user to increase tension between the fabric sidewall 108 and the gate frame 102 to provide additional structural integrity when in the in-use configuration.
As discussed in greater detail below, the gate 100 can be collapsed/folded into a storage configuration whereby the gate 100 has a compact footprint for portability (See, e.g.,
As shown in
Storage case/sleeve 112 demonstrates one example of the compact footprint achieved by the gate 100 in the collapsed/folded configuration. In this preferred example, and as is shown more clearly in
On the other hand, the overall height H2 of the gate 100 in the collapsed/folded configuration is preferably 50% less than the overall height H2 of the gate frame 102 of the gate 100 in the in-use/unfolded configuration, and more preferably, at least 90% less. Accordingly, the ratio over the overall height H1 in the in-use/unfolded configuration relative to the overall height H2 in the collapsed/folded configuration is preferably between 2:1 to 10:1. In one preferred example, the ratio over the overall height H2 in the collapsed/folded configuration relative to the overall height H1 in the in-use configuration is 50±10%. The compact footprint of the gate 100 in the collapsed/folded configuration also preferably includes an overall cross-wise width CW2 (See
In one non-limiting preferred example, the overall height H1 is equal to 27 inches, the maximum overall width W1 is equal to 48 inches, and the overall cross-wise width CW1 is 2.25 inches when the gate frame 102 is in the in-use configuration (See
In another non-limiting preferred example, the overall height H1 is equal to 34 inches, the maximum overall width W1 is equal to 60 inches, and the overall cross-wise width CW1 is 2.25 inches when the gate frame 102 is in the in-use configuration (See
In another non-limiting preferred example, the overall height H1 is equal to 39 inches, the maximum overall width W1 is equal to 72 inches, and the overall cross-wise width CW1 is 2.25 inches when the gate frame 102 is in the in-use configuration (See
Thus, the second and third frame members 102-1, 102-3 preferably provide a cavity capable of receiving at least a portion of the first and second extendable members 103-1, 103-2, respectively, and allow a user-supplied force, e.g., applied along the X axis, to increase/decrease the overall width of the gate 100. Stated differently, the first and third frame members 102-1, 102-3 and corresponding first and second extendable sections 103-1, 103-2 provide telescoping frame members/arrangements to allow a user to selectively set the overall width of the gate 100 during use.
Continuing on, the gate 100 includes first and second frame locks 116-1, 116-2 to switchably lock and unlock the first and second extendable portions 103-1, 103-2 respectively. Each of the first and second frame locks 116-1, 116-2 at least partially surround and securely couple to an associated frame member (e.g., 102-1, 102-3). The first and second frame locks 116-1, 116-2 can include a locking arrangement, such as a detent mechanism, to prevent movement of the frames 102-1, 102-3 relative to their respective extendable portions along the X axis, for example. Thus, the first and second frame locks 116-1, 116-2 allow a user to increase/decrease the overall width of the gate 100 via the telescoping frame members. The gate 100 can include a plurality of predefined extents based on, for instance, openings provided along the extendable portions 103-1, 103-2 that engage with the detent of the first and second frame locks 116-1, 116-2, as discussed in greater detail below.
As further shown in
Of course, the risk of gate displacement and/or injury to people/pets substantially decreases when the gate 100 gets fully transitioned from a storage configuration (as shown and described below) to the in-use configuration shown in
Preferably, the gate 100 includes a nominal expected loading of at least about 1-300 pounds, although other nominal load targets are within the scope of this disclosure. For instance, in instances where the gate 100 aims to withstand loads of up to 300 pounds or more applied against either side (i.e., force applied against member(s) and/or the fabric sidewall 108) materials for the members and hinge joints and/or fabric sidewall 108 can be selected to maximize rigidity. For instance, the gate 100 can include frame members formed or otherwise reinforced with metal such as steel, aluminum, titanium, or a suitably rigid plastic. In addition, the gate 100 can include additional features to secure the same into a doorway using, for instance, hooks, slots, or other suitable devices that can securely couple the gate 100 into an opening for use as a barrier.
As is shown, the plurality of hinged couplers include a first set/pair of hinged couplers (104-1, 104-2) and a second set/pair of hinged couplers (106-1, 106-2). Each of the plurality of hinged couplers include a body that defines first and second openings disposed substantially transverse with each other to receive and couple to the ends of frame members 102. Thus, the frame members extend substantially transverse relative to each other, and preferably at substantially a right angle (e.g., 90±5 degrees), when an end of each gets inserted at least partially into the openings of the hinged couplers.
Continuing on, the first pair of hinged couplers (104-1, 104-2) that define at least a portion of the rectangular profile of the gate are preferably diagonally disposed relative to each other and form opposite corners of the gate 100. To this end, an imaginary straight line drawn across the gate 100 (e.g., along the line shown generally at 118) intersects with both of the hinged couplers 104-1, 104-2. Likewise, the second pair of hinged couplers 106-1, 106-2 also define at least a portion of the rectangular profile of the gate 100 and are also preferably diagonally disposed relative to each other and form the other corners of the gate 100.
Structure and function of the first and second pairs of hinged couplers forming the gate 100 will now be discussed in turn. The first pair of hinged couplers (104-1, 104-2) each include a segmented/multi-portion body, wherein the body segments/portions define knuckles/projections that interlock with each other to allow for rotation about a first rotational axis 118 (See
Likewise,
Continuing with
Accordingly, the rotational axis 118 of the hinged couplers 104-1, 104-2 allows for the gate 100 to be folded substantially in half to bring the first and second frame members 102-1, 102-2, substantially in parallel with each other, and likewise, the second and third frame members 102-2, 102-3 substantially in parallel with each other. Stated differently, the gate 100 includes a clamshell hinge arrangement based on hinged couplers 104-1, 104-2 providing a continuous/common hinge that extends along the first rotational axis 118 to allow for bifurcation of the gate 100 into two (substantially equal) portions that can be joined or at least brought in close proximity with each other. To this end, and for simplicity, the first and second hinged couplers 104-1, 104-2 may be referred to as first and second clamshell hinges. One example of the gate 100 folded into this intermediate storage position is shown in
On the other hand, each of the hinged couplers 106-1, 106-2 allow for rotation about a second rotational axis 120. The second rotational axis 120 extends substantially transverse relative to the first rotational axis 118 and also extends substantially transverse relative to the plane in which the gate 100 extends when in the in-use configuration. Accordingly, the hinged couplers 106-1 and 106-2 each define a hinge joint or pivot joint to allow for their associated frame members to pivot and rotate about the second rotational axis 120 towards each other. Thus, each of the hinged couplers 106-1 and 106-2 may also be referred to herein as first and second pivot hinges.
However, it should be noted that each of the hinged couplers 106-1, 106-2 are preferably “locked” and prevent rotation when the gate 100 is in the in-use configuration as is shown in
On the other hand, when the gate frame 102 of the gate 100 is transitioned to the folded/intermediate storage configuration as shown in the example embodiment of
Turning again to the example embodiment of
The push-button frame locks 902 can utilize a detent mechanism similar to that of the frame locks 116-1, 116-2, the description of which will not be repeated for brevity. However, the push-button portion of the push-bottom frame lock 902 can utilize, for instance, a spring bias that changes the tactile ‘feel’ of the button 904 in response to whether the gate is in a storage or in-use configuration. For instance, as discussed above the frame includes extendable sections 103-1, 103-2 that corresponds with frame members 102-1 and 102-3, respectively. The push-bottom frame lock 902 can work in conjunction with the extendable sections and engage one or more detent positions as the gate transitions from the storage to in-use configuration. In response to extending the gate to one or more of the detent positions, the button 904 may indicate a ‘locked’ position based on a spring force that gets applied to the button 904 in response to encountering the detent. This spring force can cause the button 904 to protrude from the push-button frame lock 902 so that a user can easily locate and manipulate the same through, for instance, a fabric covering.
In use, a user may therefore run their fingers along the fabric/material surrounding the frame member 102-3 until their hand encounters the button 904 to displace/push the same and ‘unlock’ the extendable sections. The curved profile and contours of the push-button frame lock 902 allows for one or more fingers to comfortably grip the same while one or more other fingers are used to apply force on to the button 904. When two or more locks are utilized, a user can simply grip each push-button frame lock and engage the locks and allow gravity to draw/collapse the extendable sections 103-1, 103-2 (
In accordance with an aspect of the present disclosure a gate device to extend across a passageway is disclosed. The gate device comprises a plurality of frame members, a plurality of hinged couplers to couple the frame members together to provide a gate frame and transition the gate frame from an in-use configuration to a storage configuration, each hinged coupler of the plurality of hinged couplers having first and second body portions rotatably coupled to each other, and wherein the hinged couplers transition the gate frame from the in-use configuration to the storage configuration based on at least a first hinged coupler of the plurality of hinged couplers having respective first and second body portions being configured to rotate relative to each other about a first axis of rotation, and at least a second hinged coupler of the plurality of hinged couplers having respective first and second body portions being configured to rotate relative to each other about a second axis of rotation, the first and second axis of rotation being substantially transverse relative to each other.
