HYBRID DRIVE-THRU AUTOMATIC TOUCHLESS DOOR SYSTEM

Description

TECHNICAL FIELD

One or more embodiments of the present disclosure relate generally to automatic touchless door systems that are operable to provide the functionality of a drive-thru window and a fully automatic touchless door.

BACKGROUND

Door systems having automatic door operators are frequently used for providing automatic opening and closing of one or more movable door members in order to facilitate ingress and egress. Some systems include door members that are swing doors that move about a pivot axis. Some door systems include sliding door members or revolving door members.

Many fast-food restaurants are seeing a rise in drive-thru service. This is likely due to the initiative to make all things as touchless as possible during and after the COVID pandemic. Currently, restaurants may use one or more standard drive thru service windows to service customers in one or more lanes. The customers are instructed to park in designated parking areas (“car-hop”) during rush hours to avoid long lines in the drive thru queue. Employees will then bring their orders directly to the customer's vehicle. Problems occur when employees need to walk through the restaurant from the kitchen and then to the customer's parking place. This inefficiency wastes valuable time during rush hour when customers still expect fast service. By allowing the employees the ability to walk out directly from the kitchen to the lot, they can get food to customers much faster and with less risk of dropping the food along the way due to the shorter walking distance.

Door products currently in the market typically only perform one function. Drive-thru windows are very common, but they do not provide full-door functionality. Automatic doors are also common without top sliding window functionality in the manner that a drive-thru window does. There are limited current solutions in the market, and these limited solutions offer limited functionality in one door package. Such solutions characteristically use surface-mounted linear drawing slides that are difficult to clean or sanitize due to the presence of particles, debris, germs, etc. Moreover, the presence of particles and debris that are captured on the linear slides reduces the overall performance of the doors. In addition, the structural configuration of linear drawing slides are more sensitive to tolerances and do not allow for vertical adjustment or vertical movement. The linear drawer slides are prone to binding caused from misalignment.

SUMMARY

In accordance with one or more embodiments of the present disclosure, a hybrid drive-thru automatic touchless door system is provided which has great operational flexibility and provides a multi-mode functionality. Such a hybrid drive-thru automatic touchless door system has a configuration that includes a flexible, changeable door that is operable for use between different operational modes, namely, a drive-thru window service mode and a full-door service mode. Such a hybrid drive-thru automatic touchless door system serves to eliminate the requirement for a separate drive-thru and a separate door entrance.

DESCRIPTION

A detailed description of apparatuses, methods, and systems, consistent with embodiments of the present disclosure is provided below. While several embodiments are described, it should be understood that the disclosure is not limited to any one embodiment, but instead encompasses numerous alternatives, modifications, and equivalents. In addition, while numerous specific details are set forth in the following description in order to provide a thorough understanding of the embodiments disclosed herein, some embodiments can be practiced without some or all of these details. Moreover, for the purpose of clarity, certain technical material that is known in the related art has not been described in detail in order to avoid unnecessarily obscuring the disclosure.

Turning to the figures, in which FIG. 1 illustrates a hybrid automatic touchless door system 100, in accordance with one or more embodiments. The hybrid automatic touchless door system 100 has a structural configuration that combines the functionality of a drive-thru window with a fully automatic touchless door.

In accordance with one or more embodiments, the hybrid automatic touchless door system 100 is configured for mounting at a frame of a commercial business or retail business, such as, for example, a fast-food restaurants having drive-thru service. Embodiments, however, are not limited thereto, and thus, the hybrid automatic touchless door system 100 may have application in an industrial or residential setting or structure.

In accordance with one or more embodiments, an example hybrid drive-thru door system 100 includes a door panel assembly 110 operable for lateral movement with respect to a frame via a guide system. The hybrid drive-thru door system 100 may have a wired powered source, a wireless power source, a replaceable battery source, or a rechargeable battery source.

As illustrated in FIGS. 1 and 2, the door panel assembly 110 is configured for mounting at the frame which defines a doorway opening. The door panel assembly 110 has a bifurcated structural configuration that includes a stationary door panel 130 and a sliding door panel 140 that is operable for automatic movement between a closed position to at least partially cover the doorway opening and an open position to at least partially expose the doorway opening.

The sliding door panel 140 has a bifurcated structural configuration that includes an upper sliding door panel member 141 and a lower sliding door panel member 142 that are split horizontally. The upper sliding door panel member 141 is releasably attached to the lower sliding door panel member 142 in a manner that facilitates selective placement of the sliding door panel 140 between a window operating mode and a door operating mode to permit ingress and egress of a user through the doorway opening. In the door operating mode, the upper sliding door panel member 141 and the lower sliding door panel member 142 are attached to each other, the attachment being released to place the sliding door panel 140 in the window operating mode.

As illustrated in FIGS. 4 and 5, the guide system has a structural configuration that provides stability and support of each sliding door panel 140 in the door panel assembly 110. The components of the guide system are concealed, and thus, not exposed to the ambient environment (e.g., dust particles, debris, rain, snow, etc.). This results in the performance of the guide system not being adversely affected by the ambient environment. The structural configuration of the guide system is also not prone to binding and facilitates vertical adjustment during movement of each sliding door panel 140. The guide system is operable to facilitate joint movement of the upper sliding door panel member 141 and the lower sliding door panel member 142 relative to the frame in the door operating mode. Such a structural configuration is also operable to facilitate independent movement of the upper sliding door panel member 141 relative to the lower sliding door panel member 142 in the window operating mode.

In accordance with one or more embodiments, the guide system includes a plurality of guide roller assemblies that include at least one lower guide roller assembly 151, at least one intermediate guide roller assembly 152, and at least one upper guide roller assembly 153. The structural configuration of each guide roller assembly 151, 152, 153 prevents the pivoting or swinging of the upper sliding door panel member 141 and the lower sliding door panel member 142.

The guide system further includes a plurality of guide tracks that include a first guide track 154 (FIG. 13), a second guide track 161, and a third guide track 163. The first guide track 154 has spaced apart guide channels 155 extending in parallel.

The at least one lower guide roller assembly 151 also includes one or more first guide wheel members 158 connected to the guide body 156 for rotation on the first guide track 154. A bias member 159, such as, for example a spring, is mounted on a guide shaft 160 and is operable to apply a bias force to the guide body 156 in a manner that facilitates vertical adjustment of the lower second door panel member 142 during movement of the lower sliding door panel member 142 along the first guide track 154 while also maintaining the guide legs 157 in the guide channels 155. The first guide track 154 is sized so as to facilitate upward and downward movement of the one or more first guide wheel members 158 when the upper sliding door panel member 141 and the lower sliding door panel member 142 are attached together or unattached.

The at least one intermediate guide roller assembly 152 is arranged at an upper region of the lower sliding door panel member 142 to facilitate movement of the lower sliding door panel member 142 in the door operating mode. The at least one intermediate guide roller assembly 152 includes one or more second guide wheel members 162 for rotation on the second guide track 161 of the guide system. The one or more second guide wheel members 162 are mounted in a concealed position between the stationary door panel 130 and the sliding door panel 140. The at least one intermediate guide roller assembly 152 is configured to engage the second guide track 161 in an operable manner that facilitates movement of the lower second door panel member 142 along the second guide track 161.

The at least one upper guide roller assembly 153 is arranged at a lower region of the upper sliding door panel member 142 to facilitate movement of the upper sliding door panel member 142 in the door operating mode and the window operating mode. The at least one upper guide roller assembly 153 includes one or more third guide wheel members 164 operable for rotation on the third guide track 163. The one or more third guide wheel members 164 are mounted in a concealed position between the stationary door panel 130 and the sliding door panel 140. The at least one upper guide roller assembly 153 is configured to engage the third guide track 163 of the guide system in an operable manner that facilitates movement of the upper sliding door panel member 141 along the third guide track 163.

As illustrated in FIG. 3, a door panel seal assembly is provided for the hybrid automatic door system 100 to prevent entry of undesirable elements (e.g., debris, water, dirt, etc.) through a gap located between each upper sliding door panel member 141 and corresponding lower sliding door panel member 142. The gap facilitates unobstructed and frictionless movement of the upper first door panel member 141 when in the window operating mode.

The door panel seal assembly includes a seal carrier 143 which is received and recessed in an interior space of a sidewall of the upper sliding door panel member 141. A first seal member 144 extends longitudinally from the seal carrier 143 to form a seal at the gap at an exterior side of the door panel assembly 110. A pair of seal members that include a second seal member 145 and a third seal member 146 extend in parallel longitudinally from the seal carrier 143 to form seals at the gap at an interior side of the door panel assembly 110. The second seal member 145 and the third seal member 146 are spaced from the first seal member 144. The third seal member 146 is configured to form a seal, in the door operating mode of the sliding door panel 140, at an interface between the upper sliding door panel member 141 and the door sill member 180. The second seal member 145 and the third seal member 146 may respectively comprise a bulb-type seal. Embodiments, however, are not limited thereto, and thus, this disclosure contemplates the second seal member 145 and the third seal member 146 respectively comprising any suitable seal configuration in other embodiments.

As illustrated in FIGS. 6, 7, and 9 the hybrid drive-thru door system 100 further includes a clamp assembly 170 that is operable to releasably interlock the upper sliding door panel member 141 and the lower sliding door panel member 142 and thereby facilitate the selective placement of the sliding door panel 140 between the window operating mode and the door operating mode.

In accordance with one or more embodiments, the clamp assembly 170 includes an upper clamp body 171 and a lower clamp body 172 that provide a visual aid to the user to visually determine when the clamp assembly 171 is engaged or disengaged. The upper clamp body 171 is arranged on the upper sliding door panel member 141, whereas the lower clamp member 172 is arranged on the lower sliding door panel member 142. The upper clamp body 171 has one or more grooves 173, and the lower clamp body 172 has a pivotally-attached clamp member 174 that is pivotably moveable via an arm member 175 between a clamped position to place the clamp assembly 170 in a locked operating state, and an unclamped position to place the clamp assembly 170 in an unlocked state. In the clamped position, a user may pivot the clamp member 174 for engagement with the upper clamp member 171 and receipt in the grooves 173. In the unclamped position, the clamp member 174 is counter-pivoted for disengagement with the upper clamp member 171 and movement out of the one or more grooves 173. The structural configuration of the clamp assembly 170 facilitates self-centering of the upper sliding door panel member 141 and the lower sliding door panel member 142. Such self-centering serves to align the upper sliding door panel member 141 and the lower sliding door panel member 142 when placed from the window operating mode to the door operating mode.

In the door operating mode, a user may place the clamp assembly 170 in the clamped or locked operating state by selectively manipulating the arm member 175 so as to facilitate engagement of the clamp member 174 and the one or more grooves 173. Such engagement interlocks the upper sliding door panel member 141 and the lower sliding door panel member 142. In that way, the upper sliding door panel member 141 and the lower sliding door panel member 142 may move jointly.

In the window operating mode, a user may place the clamp assembly 170 in the unclamped or unlocked operating state by selectively manipulating the arm member 175 so as to facilitate disengagement of the clamp member 174 and the one or more grooves 173. Such disengagement releases the attachment of the upper sliding door panel member 141 and the lower sliding door panel member 142.

The one or more safety light sources include one or more upper safety light sources 191 and one or more lower safety light sources 192. The one or more upper safety light sources 191 are recessed into an upper sidewall region of the jamb 120 so as not to protrude therefrom. The one or more upper safety light sources 191 are operable to emit infrared holding beams in a horizontal direction across the doorway opening at the upper region of the door panel assembly 110, particularly, each upper first door panel member 141. The one or more lower safety light sources 192 are recessed into a lower sidewall region of the jamb 120 so as not to protrude therefrom. The one or more lower safety light sources 192 are operable to emit infrared holding beams from the door panel assembly 110 in a horizontal direction across the doorway opening at the lower region of the door panel assembly 110, particularly, each lower first door panel member 142.

The one or more safety sensors include one or more upper safety sensors 193 that correspond with the one or more upper safety light sources 191 and one or more lower safety sensors 194 that correspond with the one or more lower safety light sources 192. The one or more upper safety sensors 193 are operable to dynamically detect when the infrared holding beams emitted by the one or more upper safety sensors 193 are traversed/breached. The one or more lower safety sensors 194 are operable to dynamically detect when the infrared holding beams emitted by the one or more lower safety light sources 192 are traversed/breached. In accordance with one or more embodiments, the one or more safety sensors may work independently from each other, or alternatively, may work in combination with each other. The one or more safety sensors may be used in any combination, and may be used redundantly to validate and improve the accuracy of the detection.

The hybrid drive-thru door system 100 additionally includes an activation system 210 for a touchless activation (e.g., in an automated operating mode) of a corresponding sliding door panel 140 by a user from the closed position to the open position to at least partially expose the doorway opening and facilitate user ingress and egress through the doorway opening. The activation system 210 includes one or more activation sensors 211 mounted spatially above the door panel assembly 110 at an interface or boundary between each sliding door panel 140 when both are in the closed position. The one or more activation sensors 211 are operable to dynamically detect, determine, assess, monitor, measure, quantify, and/or sense a presence of a user who is approaching the door panel assembly 110 within a user-determined and/or predetermined threshold distance from a sliding door panel 140. Alternatively or additionally, one or more activation sensors 211 may be mounted spatially above the door panel assembly 110 to provide overhead sensing functionality.

In accordance with one or more embodiments, the one or more activation sensors 211 comprises one or more motion sensors, or one or more proximity sensors. Embodiments, however, are not limited thereto, and thus, this disclosure contemplates the one or more activation sensors 211 comprising any suitable sensor that sense a user presence.
