Description

Background of the invention

The present invention relates to a device for persons with reduced mobility to access the establishments receiving the public whose entry includes at least one step. The present invention finds in particular an application to respond to legislative changes requiring institutions receiving the public to be accessible, inter alia, to persons with reduced mobility.

Various devices are known that allow a person with reduced mobility to access an establishment whose entry has several steps.

There are for example removable inclined ramps temporarily installed by the staff of the establishment.

This type of device can not be set up by the person with reduced mobility; in addition, it usually has a slope greater than 5%, which does not allow it to be used by a person with reduced mobility without assistance.

An alternative solution to the problems raised by the use of an inclined ramp is proposed by the document EP 0 915 778 , which discloses a motorized lift device for moving a platform between a lowered first level, on the ground, near the entry of the establishment, and a second level, raised, also near the entrance of the building. 'establishment. The displacement of the platform is made possible by a parallelogram mechanism. This solution solves some of the problems previously mentioned; on the other hand, such a device substantially encumbers both the interior space of the establishment and the public domain surrounding the entrance of the establishment. In addition, the parallelogram mechanism requires a high accuracy of adjustment, which makes the lifting device difficult to adapt to different setup configurations.

Object and summary of the invention

• deux moyens mobiles, disposés de part et d'autre de l'entrée du local et permettant de déplacer la plate-forme entre la position inférieure et une position intermédiaire disposée à la verticale de la position inférieure et à la même hauteur que la position supérieure ;
• un système de translation horizontale permettant de déplacer la plate-forme entre la position intermédiaire et la position supérieure.

The present invention aims to allow any type of institution receiving the public, whose entry includes at least one step, to be accessible to people with reduced mobility, without the persons with reduced mobility do not require assistance. This object is achieved by the fact that the invention relates to a lift for persons with reduced mobility intended to allow access to a room with an entrance, and to compensate for the difference in height between a lower position located outside the room and an upper position located inside the room, the elevator comprising a platform and a mechanism for moving the platform between the lower and upper positions, the mechanism comprising:

• two moving means, arranged on either side of the entrance of the room and for moving the platform between the lower position and an intermediate position disposed vertically from the lower position and at the same height as the upper position. ;
• a horizontal translation system for moving the platform between the intermediate position and the upper position.

Thus, this device can equip the premises for public reception, the entry includes at least one step, and allow people with reduced mobility to access, autonomously, within the premises. The device has a small footprint inside the room when not in use. It does not significantly alter the external appearance of the room, nor does it reduce the dimensions of the opening of the room entrance. It does not permanently interfere with the public domain surrounding the entrance to the premises. It can be installed quickly, and without requiring extensive work, in many different configurations of local. In addition, once installed, the device allows people with reduced mobility, in complete autonomy and in complete security, to access the premises, without access to the premises being compromised for the valid persons.

The invention is described below in a series of alternative embodiments, which may be considered alone or in combination with one or more of the previous ones.

Advantageously, each of the moving means comprises a holding device for holding the platform during its vertical displacement between the lower position and the intermediate position.

This provision makes it possible to limit the encroachment on the public domain surrounding the premises of the device when it is in operation. functioning to allow the entry or exit of a person with reduced mobility.

Advantageously, each of the movable means comprises a housing, preferably a groove, in which engages one of the lateral edges of the platform.

This structure of the movable means enables them to cooperate with the platform and to support it in order to allow its vertical displacement, while allowing its horizontal displacement relative to the moving means, when the platform is moved between the upper and intermediate positions. .

Preferably, the platform further comprises stop means intended to come into contact with a portion of the moving means in order to limit the travel of the platform during its horizontal movement.

This arrangement allows the platform to be secured to the mobile means. The person with reduced mobility, when on the platform, can be moved vertically safely. In addition, the abutment means of the platform allow the platform, when the moving means reach the intermediate position from the lower position, to be in a position such relative to the horizontal translation system that it can carry out a horizontal translation directed towards the interior of the establishment, by means of the system of horizontal translation. Preferably, the stop means allow the platform to be aligned with the horizontal translation system, so that the actuation of the horizontal translation system allows to translate the platform horizontally.

Advantageously, the elevator comprises two vertical elements arranged on either side of the entrance of the room, the vertical elements comprising vertical translation drive means for vertically moving the moving means relative to the vertical elements.

Thus, the presence of the vertical elements arranged on either side of the entrance of the room does not hinder access to the room for people valid, and maintain the width of the opening of the entrance. In addition, the movable means, free to move along the vertical elements, and the platform, guided by the moving means, can reach the lower position on the ground of the public domain.

Advantageously, the movable means have an extended position in which they cooperate with the platform, and a retracted position in which they are hidden in the vertical elements. It is therefore understood that the moving means do not cooperate with the platform when they are in the retracted position.

Preferably, the movable means are brought into the retracted position when the platform is in the upper position.

Thus, this arrangement of the mobile means allows them not to impede the public domain when the elevator is not in operation. Passersby or vehicles circulating near the local are not likely to meet the mobile means. The deployed position of the mobile means allows, conversely, to signal to passers or vehicles circulating near the entrance of the room that the elevator is in operation, or about to be actuated.

Advantageously, the elevator further comprises a box for containing the platform when it is in the upper position.

Thus, when the platform is in the upper position, and it is not in operation to allow access to the premises to a person with reduced mobility, the size of the device is reduced.

Advantageously, the box is embedded in the floor of the room.

This arrangement allows the elevator to adapt to any room configuration. In particular, it is not necessary to modify the door disposed at the entrance of the room. The box can be, for example, included in the thickness of the screed and tile that form the threshold of the room.

Preferably, the horizontal translation system comprises an intermediate deck adapted to cooperate with the platform and displacement means for translational movement of the intermediate deck.

Thus, the intermediate deck and the displacement means allow the platform to perform a horizontal translation between the upper and intermediate positions.

Advantageously, the intermediate apron cooperates with the platform when the platform is in the intermediate and upper, and the intermediate deck does not cooperate with the platform, when the platform is in the lower position.

Thus, the intermediate deck allows to guide the platform in the horizontal translation; it does not cooperate with the platform when it performs the vertical translation, allowing the platform to reach the lower position on the ground of the public domain.

Advantageously, the intermediate deck is arranged in an upward direction when the platform is in the lower position.

Thus, the intermediate deck is inclined so as to cover the steps when the platform performs the vertical translation between the lower and intermediate positions; the intermediate deck provides additional safety for the person with reduced mobility by reducing the space between the threshold of the room and the platform.

Preferably, the platform and the intermediate deck comprise releasable coupling means for coupling the platform and the intermediate deck when the platform is in the intermediate and upper position, and for decoupling the platform and the platform. intermediate deck when the platform is in the lower position.

The presence of the releasable coupling means allows on the one hand the platform to be detached from the intermediate deck, during the downward vertical translation, so that the platform can reach the lower position, and on the other hand, at the platform to be secured to the intermediate deck, during the upward vertical translation, so that when the platform reaches the intermediate position, it can be pulled in horizontal translation in the direction of the inside the room, by the horizontal translation system coupled to the intermediate deck.

Advantageously, the elevator further comprises at least one barrier having a raised position and a tilted position.

Advantageously, the barrier is brought into the tilted position when the platform moves between the lower and upper positions.

Thus, the barrier is an additional security for the person with reduced mobility when it is on the platform and it is moving between the lower and intermediate positions. In addition, the barrier is a means of defining the space required for the deployment and movement of the elevator. Finally, the raised position of the barrier reduces the size of the elevator when it is not used to allow access to the premises to a person with reduced mobility.

Preferably, the barrier has the raised position when the platform is in the lower position.

Thus, the raised barrier allows the person with reduced mobility to take place on the platform when it is in the lower position. The person reaches the platform by one of its side edges, the installation of the elevator thus not requiring a length of public domain greater than that of the platform.

Advantageously, the barrier is mounted on one of the moving means, and the movable means comprises tilting means for tilting the barrier.

Thus, the barrier is integral with the movable means and accompanies the vertical translation of the platform. It makes it possible to secure the person with reduced mobility on the platform during his movement between the lower and intermediate positions.

Advantageously, the platform comprises a security system at one of its ends and pivoting means for pivoting the security system between a folded position and a raised position.

Preferably, the security system is in the form of a plate extending along the width of the platform.

Preferably, the pivoting means are arranged to bring the safety system in the raised position when the platform moves between the lower and upper positions, and in the folded position when the platform is in the upper position.

The safety system makes it possible to secure the movement of the person with reduced mobility when the person is on the platform between the lower and middle positions, or when the person with reduced mobility moves between the threshold of the room and the flat in the intermediate position. In addition, when the elevator is not used, the security system has a folded position to reduce the congestion of the elevator on the private space of the premises and on the public domain.

The invention further relates to a method of moving the elevator for persons with reduced mobility according to the invention comprising a step during which the barrier is brought in the tilted position while the platform is moved horizontally of the upper position to the intermediate position, followed by a step in which the platform is moved vertically from the intermediate position to the lower position, followed by a step in which the barrier is brought to the raised position, followed a step during which a person with reduced mobility is positioned on said platform.

Preferably, the method also comprises a step during which the barrier is brought into the tilted position, followed by a step during which the platform is moved vertically from the lower position to the intermediate position, followed by a step in which the platform is moved horizontally from the intermediate position to the upper position while the barrier is brought into the raised position.

Advantageously, the method also comprises a step during which the moving means pass from a retracted position in the vertical elements to a deployed position in which they cooperate with the platform.

Detailed description of the invention

In the example shown in Figure 1A , the elevator 10 according to the invention is installed to allow access for persons with reduced mobility to a room provided with an entrance E. As shown in FIG. Figure 1A , the entry E is delimited by two wall portions L, L ' and has several steps M1, M2, M3. For the sake of clarity, the door for closing the entry E is not shown on the Figure 1A .

The entrance E of the room is accessible from the public domain located outside the room, in this example from a sidewalk P.

• tel que représenté en particulier par les figures 1A et 2 , l'élévateur 10 peut tout d'abord se trouver dans une position supérieure C, située dans cet exemple à l'intérieur du local, à l'horizontale de la marche la plus haute M3 ;
• tel que représenté en particulier par les figures 3A et 6 , l'élévateur 10 peut également se trouver dans une position inférieure A, à l'extérieur du local, sur le trottoir P, au pied de la marche la plus basse M1 ;
• tel que représenté par les figures 4 et 5 , l'élévateur 10 peut enfin se trouver dans une position intermédiaire B, située à la verticale de la position inférieure A et à l'horizontale de la position supérieure C.

As will be seen more clearly in the description of the various figures, the elevator 10 can be in different positions during its operation:

• as represented in particular by the Figures 1A and 2 , the elevator 10 may first be in an upper position C, located in this example inside the room, to the horizontal of the highest step M3;
• as represented in particular by the Figures 3A and 6 The elevator 10 may also be in a lower position A, outside the room, on the sidewalk P, at the foot of the lowest step M1;
• as represented by the figures 4 and 5 , the elevator 10 may finally be in an intermediate position B, located vertically from the lower position A and horizontally from the upper position C.

As shown on the Figure 1A , the elevator 10 comprises two vertical elements 28, 28 ', arranged on either side of the steps M1, M2, M3 of the entry E.

Each vertical element 28, 28 ' has a lower end 48, 48', a lower support element 50, 50 ' and an upper support element 52, 52'. Each vertical element 28, 28 ' is supported on the one hand on the lowest step M1, via the lower bearing element 50, 50', on the other hand on the highest step M3 , through the upper support element 52, 52 '. The lower end 48, 48 ' of each vertical element 28, 28' reaches the sidewalk P, without bearing on its surface. The vertical elements 28, 28 ' are therefore, for example and without limitation, permanently mounted on either side of the steps M1, M2 and M3 of the entry E.

Each vertical element 28, 28 ' also comprises a movable means 16, 16' which will be described in more detail with the observation of the following figures.

As we see on the Figure 1A , on which the elevator 10 is not in operation, the movable means 16, 16 ' have a retracted position in which they are concealed in the vertical elements 28, 28'; in this position, the movable means 16, 16 ' do not exceed wall portions L, L' and do not encroach on the sidewalk P.

On each movable element 16, 16 ' is mounted a barrier 38, 38', in the raised position on the Figure 1A .

Referring to the Figure 1A it is found that the presence of the vertical elements 28, 28 ' on either side of the entrance E of the room very slightly reduces the width of the entrance E of the room. In addition, and as detailed above, the vertical elements 28, 28 ' taking support that on the lowest step M1 and on the highest step M3, the elevator 10 according to the invention does not require the presence of wall portions L, L ' to be installed; it can equally well be installed at the entrance E of a glazed room or on a portion of a staircase.

In the example shown in figure 2 , the operation of the elevator 10 has been engaged. A person with reduced mobility F, represented by a wheelchair, is on the sidewalk P, near the entrance E of the room. By pressing the control buttons 46 accessible from the sidewalk P, the person with reduced mobility F activates the operation of the elevator 10.

However, it could conceive an actuation of the elevator 10 engaged by any other means, such as a remote control held by the person with reduced mobility F, without departing from the scope of the present invention.

In addition, it is also conceivable, within the scope of the present invention, the presence of a buzzer and / or light on the elevator 10, by means of which the person with reduced mobility F, located outside the local on the sidewalk P, signals to a person located inside the premises his desire to operate the elevator 10 to allow him access to the local; this buzzer and / or light may also have the function of signaling the operation of the elevator 10.

As shown on the figure 2 , the actuation of the elevator 10 begins with the deployment of the movable means 16, 16 '. The passage from the retracted position to the deployed position of the movable means 16, 16 ' can be achieved, for example and without limitation, by means of jacks disposed in the vertical elements 28, 28'. The moving means 16, 16 ' move towards the outside of the room, in order to be positioned vertically on the sidewalk P.

The mobile means 16, 16 ' comprise tilting means 40, 40' connected to the barriers 38, 38 '.

Thus, when the movable means 16, 16 ' are in the deployed position, and as shown in FIG. figure 2 by means of the arrows, the tilting means 40, 40 ' are actuated in order to tilt the barriers 38, 38'.

The barriers 38, 38 ' brought in the tilted position make it possible to delimit the space of the sidewalk P necessary for the operation of the elevator 10.

According to the invention, the elevator 10 also comprises a platform 12, an intermediate apron 32 and displacement means 34, visible on the figure 3A .

For example and without limitation, the platform 12 consists of a set of welded metal strips and its thickness does not exceed 2 cm; the platform 12 can thus support a load of up to 250 kg when the platform 12 is in the intermediate position B.

When the platform 12 is in its upper position C as represented by the Figure 1B , the platform 12, the intermediate deck 32 and the displacement means 34 are housed in a box 30. The box 30 is embedded in the threshold S of the room.

The elements contained in the box 30 have dimensions such that the thickness of the box 30 does not exceed a few centimeters. Therefore, the box 30 can easily be embedded in the threshold S of the room. To do this, a disbursement of a few centimeters must be made in the threshold S, making the installation of the elevator 10 according to the invention easily achievable in any type of room; in particular, the small thickness of the box 30 allows the elevator 10 to be also installed in premises with a cellar.

It could also, for example for a room whose entry E has no door, or for installation on a portion of stairs, simply put the box 30 on the ground located near the highest step M3, without departing from the scope of the present invention.

The presence in the box 30 of the platform 12, the intermediate deck 32 and the displacement means 34 also allows a standard exchange in case of malfunction: the only replacement of the box 30 and its contents allows the room to have again the elevator 10 in working condition, without requiring a long and restrictive intervention that would prevent access to the entrance E of the local.

In addition, the integration of the box 30 in the floor of the threshold S of the room does not interfere with access or traffic in the room.

As shown on the figure 3A , the platform 12 translates horizontally from the box 30 recessed inside the room, to the sidewalk P. This horizontal translation is achieved by means of a horizontal translation system contained in the box 30. The system of horizontal translation may, for example and without limitation, include a motorized device that allows the displacement of the platform 12 by means, for example, of a belt connected to the displacement means 34.

As shown on the figure 3A , The intermediate deck 32 includes two opposite edges 54, 55; the first edge 54 is integral with the displacement means 34, while the second edge 55 is securable to the platform 12.

Thus, the rotation of the belt of the horizontal translation system, driven by the motor, allows the translation of the displacement means 34, and hence the translation of the intermediate deck 32. As a result, the translation of the intermediate deck 32 causes the translation of the platform 12.

As shown on the figure 3A , the mobile means 16, 16 ' are provided with a horizontal housing 20, 20' whose axis belongs to the plane defined by the horizontal translation of the platform 12.

The platform 12 has two lateral edges 22, 22 ' and two opposite ends 24, 26; as shown on the figure 3B which constitutes a detailed and exploded view of the moving means 16 and its cooperation with the platform 12, the platform 12 translates horizontally, one of its lateral edges 22 engaging in the housing 20 of the moving means 16. This housing also guides the horizontal displacement of the platform 12 when the latter is brought to intermediate position B. The lateral edge 22 of the platform 12 has a thickness greater than the thickness of the rest of the platform 12, which constitutes a stop means 25 intended to come into contact with a part of the moving means 16; thus, the horizontal travel of the platform 12 is limited by the stop means 25 of the lateral edge 22 in the housing 20. The platform 12 is thus configured to be displaced, preferably to be slid horizontally, with respect to moving means 16, 16 ', when the platform 12 moves between the intermediate positions B and upper C, the lateral edges 22, 22 ' being slidably guided in the housings 20, 20' formed in the movable means 16, 16 '. As a result, the platform 12 is thus configured to be displaced, preferably to be slid horizontally, relative to the vertical members 28, 28 '.

In a symmetrical manner, the housing 20 ' of the movable means 16' cooperates with the lateral edge 22 ' of the platform 12, the lateral edge 22' of the platform 12 having a greater thickness than the thickness of the remainder of the the platform 12 which constitutes an abutment means 25 ' also abutting in the housing 20' in order to limit the horizontal travel of the platform 12.

As represented in a non-limiting manner on the figure 3B , the stop of the platform 12 on the movable means 16, 16 ' is allowed by the variation of the thickness of the platform 12; it could however conceive any other stop means for limiting the horizontal travel of the platform 12, such as a retractable device disposed in the platform 12, without departing from the scope of the present invention.

As shown on the figure 3A , a security system 42 is disposed at one of the ends 26 of the platform 12. When the platform 12 is moving between the upper position C and the lower position A, the security system 42 has a position raised allowing it to form a rim to the platform 12.

The security system 42 is secured to the platform 12 by means of pivoting means 44. The pivoting means 44 allow the security system 42 to move from a folded position when the elevator 10 is not in operation, as shown in the Figures 1A and 2 previously described, at a raised position, represented in particular on the figure 3A .

Referring to the figure 3B it is found that the security system 42 has the form of a plate having a width less than the width of the platform 12, so that the security system 42 does not hinder the engagement of the platform. 12 in the housings 20, 20 ' of the movable means 16, 16'.

At the end of the horizontal translation between the upper C and intermediate B positions, and as detailed above, the platform 12 abuts on the movable means 16, 16 '; the platform 12 is is then in the intermediate position B, the end 24 of the platform 12 being positioned vertically on the sidewalk P located at the foot of the steps M1, M2 and M3.

As shown on the figure 4 , the platform 12 then performs a vertical translation, allowing it to move from the intermediate position B to the lower position A.

The housings 20, 20 ' of the movable means 16, 16' constitute holding devices for holding the platform 12 during its vertical movement between the intermediate positions B and lower A.

The vertical translation is made possible by the presence, in the vertical elements 28, 28 ', of vertical translation drive means for vertically moving the moving means 16, 16' along the vertical elements 28, 28 '.

The vertical displacement of the movable means 16, 16 ' along the vertical elements 28, 28' can be achieved, for example and without limitation, by means of a motor disposed in one of the vertical elements 28. The motor operates for example, a worm screw also disposed in said vertical member 28, which allows the sliding means 16 to slide in said vertical member 28. An axis, for example at the foot of the lowest step M1, connects the vertical members 28, 28 ', so that the motor disposed in said vertical member 28 also allows sliding of the movable means 16' in the second vertical member 28 '.

One could, however, design an elevator 10 on which each vertical element 28, 28 ' comprises a motor, or any other means of vertical translation drive to vertically move the movable means 16, 16' along the vertical elements 28, 28 ', without departing from the scope of the present invention.

As shown on the figure 4 , the platform 12 and the intermediate deck 32 comprise detachable coupling means 36, respectively disposed on one of the ends 24 and one of the edges 55. For example, and in a nonlimiting manner, the releasable coupling means 36 consist of curved loops and hooks.

So, and as represented on the figure 4 , the platform 12 disengages from the intermediate deck 32 during its downward vertical translation to the lower position A. The intermediate deck 32, bound the displacement means 34 by an axis disposed on one of the edges 54 of the intermediate deck 32, is then arranged in an inclined manner on the steps M1, M2, M3 of the entrance E of the room. The intermediate deck 32, thus inclined, is a safety device to partially fill the space formed between the highest step M3 and the platform 12 when the latter translates vertically between the lower position A and intermediate B.

As detailed above, the ends 48, 48 ' of the vertical elements 28, 28' are arranged near the floor of the sidewalk P, whereby the moving means 16, 16 ' allow the platform 12 to reach the floor. pavement floor P.

As shown on the figure 5 , the tilting means 40, 40 ' disposed on the movable means 16, 16' then tilt the barriers 38, 38 ' so that they pass in the raised position and allow the person with reduced mobility F to sit on the plate 12. A lift 10 could be designed on which only one of the barriers 38, 38 ' would be tilted to allow the person with reduced mobility F to take place on the platform 12 without departing from the scope of the present invention.

Referring to the figure 5 it is found that the platform 12 is dimensioned so that its thickness allows the person with reduced mobility F to sit autonomously on the platform 12 when the barriers 38, 38 ' are brought into the raised position.

Once the person with reduced mobility F is positioned on the platform 12, the tilting means 40, 40 ' pass the barriers 38, 38' in the tilted position.

When it is on the platform 12, the person with reduced mobility F benefits from the safety devices present on the different sides of the platform 12: the ends 24, 26 of the platform 12 are secured respectively to means of the intermediate deck 32 inclined on the steps M1, M2, M3 and the security system 42 arranged in the raised position when the platform 12 is between the lower A and upper position C. On the other hand, the side edges 22 , 22 ' of the platform 12 are secured by means of the barriers 38, 38' which, being mounted on the movable means 16, 16 ', accompany the platform 12 during the vertical translation.

As shown in particular on the figure 4 , and in a nonlimiting manner, the barriers 38, 38 ' comprise several horizontal tubular elements 58, 58' which make it possible to secure the space delimited by the platform 12 intended to receive and move the person with reduced mobility . could design barriers 38, 38 ' comprising for example a single tubular element 58, 58' or constituted by a panel, without departing from the scope of the present invention.

In addition, the lateral edges 22, 22 ' of the platform 12 comprise a notch 56, 56' in which a portion of the barriers 38, 38 ' can engage, so that, in case of pressure from the person with reduced mobility F placed on the platform 12 on one of the barriers 38, 38 ', the barrier 38, 38' remains attached to the platform 12; thus, the presence of notches 56, 56 ' on the platform prevents the formation of a space through which a portion of the wheelchair of the person with reduced mobility F could engage.

As shown on the figure 6 , once the person with reduced mobility F has taken place on the platform 12, the reverse displacements to those detailed at the observation of the Figures 1A to 4 are realized. The platform 12 translates first vertically between the lower position A and the intermediate position B. During the upward vertical translation, the detachable coupling means 36 allow the platform 12 and the intermediate deck 32 to be solidarized again.

Once the platform 12 reaches the intermediate position B, the person with reduced mobility F can enter the room, the intermediate deck 32 constituting a horizontal ramp between the platform 12 in the intermediate position B, and the threshold S of the room.

As a result, the platform 12, driven by the intermediate deck 32 and the displacement means 34 actuated by the horizontal translation system, translate horizontally between the intermediate position B and the upper position C, reached in the chamber 30 of the elevator 10.

When the platform 12 reaches the upper position C, the pivoting means 44 disposed on the end 26 of the platform 12 allow to pass the security system 42 in the folded position. As shown on the Figures 1A and 2 , and in a non-limiting way, the security system 42 in folded position is the nose of the highest step M3.

Through the tilting means 40, 40 ' disposed on the movable means 16, 16', the barriers 38, 38 ' are then raised.

Finally, the movable means 16, 16 ' pass in the retracted position, so as not to encroach on the sidewalk P surrounding the entrance E of the room.

The person with reduced mobility F will of course be able to leave the room by means of the elevator 10, following the steps previously described in the observation of the Figures 1A to 4 .

As it appears from the observation of the various figures, the platform 12 encumber the sidewalk P only during the time required for the person with reduced mobility F to access the platform 12.

The whole of the description above is given by way of example, and is therefore not limitative of the invention.

In particular, the invention, although particularly suitable for people with reduced mobility, can just as easily be used for people walking a stroller or for merchants with heavy loads to enter the premises.
