Description

Technical Field

[0001] The utility model belongs to hotel service products, and particularly relates to a service cart that does not require reserved space for opening the door. Background Art

[0002] Hotel service carts are generally used by staff to provide various services such as delivering meals, delivering items, and cleaning. They are usually equipped with a supporting and accommodating structure for placing items, wheels, handrails, etc., and can be conveniently pushed through the hotel.

[0003] When transporting items that need to be blocked, such as food and relatively private items, hotels generally use service carts with enclosed cabinets for transportation. Most of these service carts have cabinet doors hinged to the side of the cabinet, and the cabinet doors open outward when taking items. For example, the patent document with the application number CN202022122613.6 discloses a fresh-keeping and heat-insulating meal cart for hotel service, including a base and a meal cart cabinet. A baffle is welded along the vertical direction on the inner wall of the meal cart cabinet, and the baffle divides the meal cart cabinet into a storage cabinet and a meal placement cabinet. Two equally spaced first partitions and second partitions are welded along the vertical direction of the baffle in the meal placement cabinet. The first partition and the second partition divide the meal placement cabinet into a snack table, a fresh-keeping cabinet, and a heat-insulating cabinet. A dust-proof cover is hinged to the outer wall of one side of the snack table, a sealing layer is adhered to the inner wall of the fresh-keeping cabinet, and T-shaped sliding rails are welded to the inner walls on both sides of the sealing layer.

[0004] The above-mentioned prior art divides the meal placement cabinet into multiple compartments, sets a sealing layer with a fresh-keeping function and a heat-insulating layer with a heat-insulating function, ensuring the freshness and temperature of the dishes. Small snacks, beverages, etc. can be placed on the snack table, improving the service quality of the hotel. By sliding drawers in each compartment and setting compartments in the drawers, it can ensure that the dishes do not mix flavors.

[0005] However, the corridors in hotels are generally narrow. When staff deliver items, they mostly need to park the service cart in the middle or near the middle of the corridor, reserving space for the outward-opening cabinet doors. That is, the service cart in the state of taking items needs to occupy a relatively large corridor width, which may prevent other people from passing normally. At the same time, the side-opening cabinet doors also have certain limitations on the standing position of the body and the freedom of movement of the arm when taking items. Summary of the Invention

[0006] In view of the problems in the related art, the utility model provides a service cart that does not require reserved space for opening the door, so as to overcome the above-mentioned technical problems existing in the prior related art.

The ends of the first chute and the second chute close to the access opening are provided with sliding openings respectively opening towards the access opening and the inner space of their own chutes. The opposite sides of the cover curtain are respectively slidably connected to the first chute and the second chute. By sliding part or all of the cover curtain into the first chute and the second chute, the access opening is exposed, and by sliding part of the cover curtain out of the first chute and the second chute, the access opening is blocked.

[0011] The cover curtain includes a plurality of transverse sheets sequentially connected along the transverse side wall. The adjacent transverse sheets are rotatably connected to each other so that the cover curtain can be bent.

[0012] Preferably, the transverse sheet has opposite first and second transverse side walls. The first transverse side wall is provided with a C-shaped groove along the length direction, and the second transverse side wall is provided with a rotating connecting edge extending along the length direction.

[0013] A plurality of the transverse sheets are sequentially connected by clamping the rotating connecting edge into the C-shaped groove. The adjacent transverse sheets are limited by the width of the opening of the C-shaped groove to form a connection that can rotate within a certain angle.

[0014] Preferably, the second transverse side wall extends and protrudes away from itself to form a transverse side beam, and the thickness of the free end of the transverse side beam increases to form the rotating connecting edge.

[0015] Preferably, the transverse sheet has a certain three-dimensional structure in the direction perpendicular to its own plane.

[0016] The two planes of the transverse sheet are respectively set as an outer sheet and an inner sheet. The same-side transverse edges of the outer sheet and the inner sheet extend towards each other and are joined to form the first and second transverse side walls. The C-shaped groove is arranged close to the outer sheet. The transverse edge of the outer sheet away from the C-shaped groove extends away from itself and towards the inner sheet to form the transverse side beam, and the thickness of the free end of the transverse side beam increases to form the rotating connecting edge. After a plurality of the transverse sheets are assembled, the inner sheet and the outer sheet are respectively flush.

[0017] The assembled cover curtain is slidably connected to the first chute and the second chute with the inner sheet facing the inside of the storage space.

[0018] Preferably, the inner sheet is divided into two inner transverse sheets along the midline position, and the transverse edges of the two inner transverse sheets that are close to each other do not contact each other and extend towards the outer sheet until they are connected to the outer sheet, forming a reinforcing rib structure.

[0019] Preferably, the rotating connecting edge is a cylindrical structure, the width of the notch of the C-shaped groove is smaller than the diameter of the rotating connecting edge but larger than the thickness of the transverse edge beam, the two ends of the C-shaped groove are open, and the rotating connecting edge slides into the groove from one end of the C-shaped groove for assembly;

[0020] Soft edge wraps are covered and fixed on both side edges of the cover curtain, the soft edge wraps limit the horizontal movement between the transverse sheets, and the two ends of several transverse sheets are flush.

[0021] Preferably, the vehicle frame is provided with at least one cabinet that is only open on the side, the interior of the cabinet forms the storage space, the open side of the cabinet serves as the access opening, and the first sliding groove and the second sliding groove are provided along the top edge on the opposite inner side walls of the cabinet;

[0022] The cover curtain is slid upwards into the first sliding groove and the second sliding groove to expose the access opening, and the cover curtain slides out of the first sliding groove and the second sliding groove to vertically hang down to block the access opening;

[0023] The outer sheet at the lowest position of the cover curtain in the hanging state is provided with an outwardly convex handle, the bottom of the cabinet is a disc-shaped structure with a certain depth, the distance between the handle and the lower edge of the outer sheet where it is located is less than or equal to the depth of the bottom of the cabinet, and after installation, the cover curtain can be pulled down to make the transverse sheet provided with the handle contact the bottom of the cabinet, and then the cover curtain blocks the access opening.

[0024] Preferably, the length inside the first sliding groove and the second sliding groove can accommodate at least more than half of the transverse sheets;

[0025] When the cover curtain is pushed upwards to open, the center of gravity of the cover curtain is located at the horizontal position where the first sliding groove and the second sliding groove are located, and the cover curtain is in a static state without external force.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0046] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0047] As Figures 1 to 4 shown, a service vehicle that does not require reserved space for opening the door includes a vehicle frame, and a plurality (four) of wheels are installed at the bottom of the vehicle frame.

[0048] The vehicle frame is provided with at least one storage space for placing food, private items, etc. The storage space has at least an access opening facing outward and opposite first side wall 301 and second side wall 302. The first side wall 301 and the second side wall 302 are respectively provided with a first chute 301a and a second chute, and the openings of the first chute 301a and the second chute face each other and are located at the same horizontal height.

[0049] This embodiment further includes at least one (specifically two) bendable cover curtain 2. The ends of the first chute 301a and the second chute close to the access opening are provided with sliding openings that are respectively open to the access opening and the inner space of their own chutes. The opposite sides of the cover curtain 2 are respectively slidably connected to the first chute 301a and the second chute. By sliding part or all of the cover curtain 2 into the first chute 301a and the second chute, the access opening is exposed, and by sliding part of the cover curtain 2 out of the first chute 301a and the second chute, the access opening is blocked.

[0050] The cover curtain 2 includes a plurality of horizontal pieces 202 sequentially connected along the horizontal side wall. Adjacent horizontal pieces 202 are rotatably connected so that the cover curtain 2 can be bent.

[0051] In this embodiment, the curtain 2 slides into the storage space when retrieving items. Compared with the outward-opening cabinet door in the prior art, this can reduce the corridor width that the service cart needs to occupy when retrieving items to a certain extent, making it suitable for relatively narrow hotel corridors. At the same time, the curtain 2 that slides up and retracts at the top of the storage space has less restrictions on the body's standing position and the freedom of arm movement when retrieving items.

[0052] On the other hand, if the cover curtain 2 is simply made of soft and flexible materials such as cloth, it is difficult to quickly push the cover curtain 2 into the slide, which affects the efficiency of the staff in taking things. Therefore, this embodiment is specially designed with connected horizontal pieces 202 to form the cover curtain 2, so that the cover curtain 2 has a certain degree of uprightness, and the staff can push the cover curtain 2 into the slide quickly and smoothly. At the same time, multiple horizontal pieces 202 are connected by rotating along the horizontal edges to enable the cover curtain 2 to bend to a certain extent, so that part of the cover curtain 2 can bend and deform to a certain extent when sliding out of the slide to avoid being too convex, thereby reducing the space occupied.

[0053] In actual production, the cross-piece 202 can be made of any material that does not bend easily after forming, such as hard plastic, acrylic, etc., without other restrictions.

[0054] Specifically in this embodiment, the frame is provided with at least one (specifically two) cabinets 3 with only sides open, and the two cabinets 3 are stacked up and down, and the interior of the cabinets 3 forms the storage space, and the open sides of the cabinets 3 serve as the access port, and the opposite inner walls of the cabinets 3 are provided with the first slide groove 301a and the second slide groove along the top edge.

[0055] The curtain 2 slides into the first sliding groove 301a and the second sliding groove by being pushed upward to expose the taking port, and the curtain 2 slides out of the first sliding groove 301a and the second sliding groove to cover the taking port in a vertically hanging state.

[0056] The rotatable connection between the transverse pieces 202 can be achieved in various ways, such as adaptively providing hinges to connect adjacent transverse pieces 202. In this embodiment, the transverse pieces 202 have opposing first and second transverse side walls. The first transverse side wall has a C-shaped groove 202b along its length, and the second transverse side wall has a rotatable edge 202c extending along its length.

[0057] The plurality of cross pieces 202 are connected in sequence by clamping the rotating edge 202c into the C-shaped groove 202b. The rotating structure is relatively simple and, compared with a hinge, is suitable for realizing a rotating connection between thin cross pieces 202. The adjacent cross pieces 202 are limited by the width of the C-shaped groove 202b to form a connection that can rotate within a certain angle.

[0058] Furthermore, the second transverse sidewall extends away from the second transverse sidewall to form a transverse side beam 202d. The free end of the transverse side beam 202d is thicker to form the pivoting edge 202c. In this embodiment, the curtain 2 needs to achieve a curvature of approximately 90°. While maintaining the aforementioned C-shaped groove 202b design, if the distance between the transverse pieces 202 is too close, the width of the transverse pieces 202 needs to be reduced and the number of transverse pieces 202 increased to achieve a more ideal curvature. Therefore, in this embodiment, the transverse side beam 202d is designed to ensure that the pivoting edge 202c is spaced a certain distance from the main body of the transverse piece 202, providing sufficient rotational space between the connected transverse pieces 202.

[0059] If the cross piece 202 is only a thin sheet structure, the strength is slightly insufficient. Therefore, in this embodiment, the cross piece 202 has a certain three-dimensional structure in the direction perpendicular to its own surface.

[0060] The two surfaces of the cross piece 202 are respectively set as the outer piece 202a and the inner piece 202e, and the horizontal edges on the same side of the outer piece 202a and the inner piece 202e extend in the direction of approaching each other and connect to form the first horizontal side wall and the second horizontal side wall. The C-shaped groove 202b is set close to the outer piece 202a, and the horizontal edge of the outer piece 202a away from the C-shaped groove 202b extends away from itself and toward the inner piece 202e to form the horizontal side beam 202d. The thickness of the free end of the horizontal side beam 202d is increased to form the rotating connecting edge 202c. The purpose of this position design is: first, the cover curtain 2 can only bend and deform toward one side to cover the object taking port, and the other side that cannot be bent just supports the uprightness requirement when the push-up cover curtain 2 slides into the slide groove; second, after multiple pieces of the cross pieces 202 are assembled, the inner piece 202e and the outer piece 202a are flush, which is more beautiful.

[0061] After assembly, the curtain 2 is slidably connected to the first sliding groove 301 a and the second sliding groove in a manner that the inner piece 202 e faces the interior of the storage space.

[0062] In this embodiment, the inner sheet 202e is divided into two inner cross sheets 202 along the center line. The adjacent horizontal sides of the two inner cross sheets 202 do not contact each other and extend toward the outer sheet 202a until they connect with the outer sheet 202a, forming a reinforcing rib structure 202f to enhance the structural strength of the cross sheet 202.

[0063] Specifically, the rotating joint 202c is a cylindrical structure, the slot width of the C-shaped groove 202b is smaller than the diameter of the rotating joint 202c but larger than the thickness of the transverse beam 202d, and both ends of the C-shaped groove 202b are open. The rotating joint 202c slides into the groove from one end of the C-shaped groove 202b for assembly, and the assembly is convenient and quick.

[0064] Based on the above assembly design, soft edges 201 are wrapped and fixed on both side edges of the cover curtain 2. The soft edges 201 restrict the horizontal movement between the horizontal pieces 202. The two ends of multiple horizontal pieces 202 are flush, shaping the cover curtain 2 and at the same time preventing the sharp edges of the horizontal pieces 202 from being exposed.

[0065] In this embodiment, the outermost piece 202a of the cover curtain 2 in the hanging state is provided with an outwardly convex gripper 203 at its lowermost position, which facilitates the staff to quickly pull down or push up the cover curtain 2 by grasping the gripper 203.

[0066] The bottom of the cabinet body 3 is a disk-shaped structure 303 with a certain depth. After the cover curtain 2 is installed, by pulling it down, the horizontal piece 202 provided with the gripper 203 can be brought into contact with the bottom of the cabinet body 3, and then the cover curtain 2 blocks the access opening.

[0067] The distance between the gripper 203 and the lower edge of the outermost piece 202a where it is located is less than or equal to the depth of the bottom of the cabinet body 3. The function of this design is that if the bottom end of the cover curtain 2 slides into the disk-shaped structure 303 of the cabinet body 3, the gripper 203 will get stuck at the edge of the access opening, preventing the bottom end of the cover curtain 2 from continuing to slide inwards. Based on the above-mentioned straightness design of the cover curtain 2 and combined with the position design of the gripper 203, in this embodiment, there is even no need to design a limiting structure in the chute to prevent the cover curtain 2 from completely sliding out of the chute due to gravity.

[0068] In actual production, the inner lengths of the first chute 301a and the second chute can accommodate at least more than half of the horizontal pieces 202, so that when the cover curtain 2 is pushed up and opened, the center of gravity of the cover curtain 2 is located at the horizontal position where the first chute 301a and the second chute are located, and the cover curtain 2 is in a static state without external force, avoiding the cover curtain 2 sliding down by itself due to gravity and affecting the staff's access to items.

[0069] In this embodiment, the sliding opening is separated from the access opening, so that the naturally hanging cover curtain 2 will not protrude too much outside the access opening or be flush with the access opening; at the same time, in this embodiment, the chute is generally designed to accommodate the horizontal pieces 202 except for the horizontal piece 202 provided with the gripper 203 and its adjacent horizontal pieces 202, so as to ensure that the access opening presents a sufficient exposed area. When the cover curtain 2 is completely pushed up and opened, the horizontal piece 202 provided with the gripper 203 is suspended outside the sliding opening, in an inclined or hanging state, facilitating the staff to grasp the gripper 203.

[0070] In this embodiment, push handles 1 are respectively installed on two opposite sides of the vehicle frame. When the staff needs to make a large turn, they only need to walk towards the push handle 1 in the opposite direction, without having to push and turn the service vehicle significantly to make a large turn. The movement is more stable, and the items on the service vehicle are not easily spilled, toppled, or dropped. At the same time, it also avoids the problem that the service vehicle needs to occupy most of the hotel corridor for a short time when making a large turn, and other people such as guests can walk through normally.

[0071] According to the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
