Description

Technical Field

[0001] The present disclosure relates to trailers for transporting one or more persons, and more particularly, to a utility trailer and a method for securing a removable seat to a utility trailer. Background Art

[0002] Utility trailers are popular items that contribute to the active lifestyle of their owners. As the name suggests, a utility trailer can be used for a variety of purposes. For example, a utility trailer can be used to transport children on a family trip or during the daily commute. A utility trailer can further naturally be used to transport luggage, pets, etc.

[0003] Most utility trailers are suitable for use as trailers during walking and running (i.e. when the user pushes or pulls the trailer with his feet). In addition, accessories are usually provided that allow the trailer to be used, for example, when skiing or to attach the trailer to a bicycle so that it can be towed.

[0004] Trailers suitable for transporting people are subject to a variety of requirements in terms of the safety they provide to their occupants, and manufacturers of utility trailers are constantly seeking to improve their products to meet and exceed these requirements. In addition, ease of use is an area of ​​continuous development, especially for utility trailers that can not only be adjusted to the activity at hand, but also carry different numbers of passengers. Utility Model Content

[0005] In view of the above, an object of the present invention is to provide an improved utility trailer and a method of securing a removable seat to a utility trailer that alleviates at least one of the disadvantages of the prior art. For example, an object of the present invention is to provide a utility trailer that has improved safety while allowing a user to adapt the utility trailer for use with one or two passengers. In addition, an object of the present invention is to facilitate the removal, attachment, and repositioning of a removable seat for a utility trailer.

[0006] These objects are achieved by the subject-matter of the independent claims. Advantageous embodiments can be found in the dependent claims as well as in the attached description and the drawings.

[0007] According to a first aspect of the present disclosure, a multi-purpose trailer for carrying at least one person is provided. The trailer comprises:

[0008] a chassis, which forms the load-bearing structure of the trailer,

[0009] a sheet element supported by the chassis,

[0010] At least one removable seat, wherein the trailer is configured for attaching the removable seat in at least two lateral positions, one of the at least two lateral positions being a central position relative to the lateral direction of the utility trailer. Thus, the weight distribution of the load in the utility trailer can be adjusted according to the number of passengers traveling in the trailer. When one passenger is present, the removable seat can be centrally positioned in the utility trailer, thereby reducing the risk of uneven loading, which could jeopardize the stability of the trailer, for example during fast turns or the like.

[0011] The utility trailer may comprise at least one upper seat attachment and at least one lower seat attachment, to which a removable seat is configured to be fixed. The at least one upper seat attachment and / or the at least one lower seat attachment may be attached to a sheet element. The provision of the upper seat attachment and the lower seat attachment facilitates the attachment and removal of the at least one removable seat to and from the utility trailer. The attachment of the respective seat attachment to the sheet element facilitates the manufacture of the trailer, since the respective seat attachment may be formed as a sheet element or may be integral with the sheet element before the sheet element is attached to the trailer. Furthermore, the chassis of the trailer does not have to be provided with any separate features for providing the upper seat attachment and the lower seat attachment, since they may be attached to the sheet element.

[0012] In an embodiment where the utility trailer comprises at least one upper seat attachment and at least one lower seat attachment, and the removable seat is configured to be fixed to the at least one upper seat attachment and the at least one lower seat attachment, the distance between the at least one upper seat attachment and the at least one lower seat attachment may be configured to vary depending on the folded state of the chassis. Thus, the attachment of the at least one removable seat is facilitated and the risk of inadvertently releasing the removable seat is further reduced.

[0013] The distance between the at least one upper seat attachment and the at least one lower seat attachment is greater in the in-use state than in the folded state of the trailer. The greater distance in the in-use state may provide a pre-tensioning force for the at least one removable seat, thereby facilitating the correct positioning of the removable seat and further securing its attachment to the utility trailer.

[0014] In an embodiment where the utility trailer includes at least one upper seat attachment and at least one lower seat attachment, and the removable seat is configured to be secured to the at least one upper seat attachment and the at least one lower seat attachment, the chassis may include a folding hinge disposed between the at least one upper seat attachment and the at least one lower seat attachment. The folding hinge facilitates controlling the distance between the at least one upper seat attachment and the at least one lower seat attachment according to a folded state of the utility trailer.

[0015] The utility trailer may include at least two pairs of upper seat accessories and at least two pairs of lower seat accessories aligned in a transverse direction of the trailer, and the removable seat is configured to be fixed to the at least two pairs of upper seat accessories and at least two pairs of lower seat accessories. The distance between each upper seat accessory and each lower seat accessory in each pair may be substantially the same as the distance between two adjacent pairs of upper seat accessories and lower seat accessories, respectively. Thus, the two pairs of upper seat accessories and / or lower seat accessories may provide three different positions of the removable seat in the transverse direction of the trailer, namely two lateral positions and one central position.

[0016] The utility trailer further comprises a plurality of straps configured to be fixed to buckles for connection to a safety belt of each removable seat, wherein one strap is arranged in the middle between each two upper seat accessories and / or lower seat accessories in the transverse direction of the trailer.

[0017] The strips may be attached to the sheet element and / or to the chassis of the trailer.

[0018] The removable seat may include at least one upper connector configured to attach a corresponding upper seat accessory and at least one lower connector configured to attach to a corresponding lower seat accessory.

[0019] Each of the upper seat attachment and the lower seat attachment may include a first opening and a second opening through which the removable seat is configured to pass. The first opening may be larger than the second opening, and wherein the first opening on at least one of the upper attachments and / or the first opening of at least one of the lower attachments are arranged in a proximal direction relative to the trailer. The larger size of the first opening facilitates insertion of the connector into the first opening, while the smaller size of the second opening reduces the risk of the connector being inadvertently detached from the seat attachment.

[0020] Each removable seat may include an opening through its seat portion, and wherein each strap is configured to extend through the opening. Thus, the strap further secures at least one removable seat to the utility trailer.

[0021] Each seat accessory may include a fixing portion configured to pass through an attachment opening in a corresponding connector. Thus, a seat accessory may be formed in a utility trailer without any through holes. The attachment opening in each connector need only be of sufficient size to allow the seat accessory to pass therethrough, thereby eliminating or reducing the risk that, for example, a child may insert a finger and become caught in either the seat accessory or the connector.

[0022] Each seat attachment may comprise a stem portion forming an attachment between the fixed portion and the utility trailer, and wherein the fixed portion is arranged at an angle relative to the stem portion. Preferably, the fixed portion and the stem portion form a T-shaped seat attachment. The stem portion facilitates screwing the fixed portion into the connector.

[0023] The fixing portion may include a reinforcing element configured to increase the rigidity of the fixing portion.

[0024] The trailer may include a reclining backrest, and wherein at least the removable seat is configured to follow the reclining of the backrest.

[0025] In a second aspect, a method for securing a removable seat to a utility trailer is provided. The utility trailer comprises:

[0026] a chassis, which forms the load-bearing structure of the trailer,

[0027] a sheet element supported by the chassis,

[0028] Wherein the utility trailer includes at least one upper seat attachment and at least one lower seat attachment to which the removable seat is configured to be secured, the method comprising the steps of:

[0029] Set up the utility trailer with the seats attached.

[0030] attaching at least one removable seat to at least one upper seat attachment and at least one lower seat attachment,

[0031] The utility trailer is arranged in a fixed state of the removable seats, whereby at least one removable seat is fixed to the utility trailer. Thus, it is easy to attach the removable seat to the utility trailer, so that the utility trailer can be easily adjusted according to the number of passengers of the trailer. This further improves the usability of the trailer and its safety.

[0032] Attaching the at least one removable seat may include passing at least one upper connector on the removable seat through a corresponding upper seat accessory and passing at least one lower connector on the removable seat through a corresponding lower seat accessory.

[0033] Attaching the at least one removable seat may include passing at least one upper seat accessory through a corresponding upper connector and passing at least one lower seat accessory through a corresponding lower connector.

[0034] Arranging the utility trailer in a seat-attached state may include at least partially folding a chassis of the utility trailer, and wherein arranging the utility trailer in a removable seat-secured state includes at least partially unfolding the chassis to a use state of the utility trailer.

The seat attachment 112, 114 may be formed from a strip of suitable material attached to the trailer 100 at opposite ends thereof, while a center portion is free, thereby forming the first opening 120 and the second opening 122. The seat attachment 112, 114 may be formed from a textile material such as webbing.

[0091] The first opening 120 may be larger than the second opening 122, and the first opening 120 on at least one upper attachment 112 and / or the first opening 120 on at least one lower attachment 114 may be arranged facing the proximal direction relative to the trailer 100. The aforementioned proximal end should be interpreted as toward the center of the backrest portions 116a, 116b. In other words, the first opening 120 on each upper seat attachment 112 may be arranged facing the corresponding lower seat attachment 114. The first opening 120 being larger than the second opening 122 facilitates attaching the connectors 212, 214 to the seat attachments 112, 114.

[0092] The first opening 120 defines an insertion direction of the connector 212 , 214 , and during attachment of the connector 212 , 214 to the seat accessory 112 , 114 , the connector is first passed through the first opening 120 and secondly through the second opening 122 .

[0093] exist Fig.13 As further shown in FIG. 1 , the width W1 of the second opening 122 of each seat accessory 112, 114 may be smaller than the width W2 of the corresponding connector 112, 114. The ratio between the width W1 and the width W2 may be between 0.3 and 0.8.

[0094] Fig.14A detailed view of a seat accessory 112, 114 according to one embodiment is shown. As illustrated, the seat accessory 112, 114 may include a fixing portion 124. As mentioned, the fixing portion 124 is configured to be inserted through the attachment opening 216 of the corresponding connector 212, 214. The fixing portion 124 may be connected to the sheet element 104 and / or the chassis 102 of the utility trailer 100 via a rod portion 122, which is configured to allow flexibility in the relative orientation of the fixing portion 124 and the sheet element 106 and / or the chassis 102. The flexibility in relative orientation facilitates attaching each connector 212, 214 to each corresponding seat accessory 112, 114. The fixing portion 124 is configured to be arranged so that the rear side 126o faces the connector 212, 214 when the connector 212, 214 is attached to the seat accessory 112, 114. The rear side 126 of each fixing portion 124 further faces towards the rod portion 122 and towards the lamina element 104 .

[0095] The fixing portion 124 and the rod portion 122 together form a substantially T-shaped seat attachment 212 , 214 .

[0096] The stem portion 122 may extend through the sheet element 106 and form a loop around a portion of the chassis 102 and / or may be secured to the chassis by other means.

[0097] The fixing portion 124 is configured to be sufficiently rigid to reduce the risk of being folded or otherwise collapsed when the seat 200 exerts tension on one or more of the associated seat accessories 112, 114. Thus, the risk of the fixing portion 124 being pulled through the attachment opening 116 in the connector 212, 214 can be reduced.

[0098] The fixing portion 124 may be made of a textile material, a plastic material, a composite material, and / or a metal material. The fixing portion 124 may be made of a different material than the rod portion 122. In one embodiment, the fixing portion 124 is made of a plastic material and is fixed to the rod portion 122 by molding the plastic material of the fixing portion 124 around the rod portion 122.

[0099] Furthermore, the stem portion 122 may be secured to the securing portion 124 by forming a loop in the stem portion 122 that extends through a corresponding opening (not shown) and surrounds a rib (not shown) formed by the opening in the securing portion 124 .

[0100] Thus, the securing portion 124 may be formed of a homogenous material having sufficient tensile strength for providing a secure connection between each connector 212 , 214 and each corresponding seat accessory 112 , 114 .

[0101] The stem portion 122 is preferably formed of a textile material such as a webbing or another high strength woven textile material. It is also contemplated that the stem portion 122 may be formed of a rubber material or a plastic material, for example.

[0102] Fig.15 An embodiment is shown in which the fixing portion 124 and the rod portion 122 are formed of the same material. The fixing portion 124 is formed by folding the material of the rod portion 122. The rod portion 122 may be folded at least once to form the fixing portion. Fig.15 In the embodiment shown in , the rod portion 122 is folded three times so that the rod portion 122 is centrally attached to the fixing portion 124, so that at least two material layers 134, 136, 138 are superimposed on each other in the fixing portion 124. Therefore, the fixing portion 124 will be provided with rigidity to reduce the risk of it being folded and accidentally pulled through the attachment opening 116 of the connector 112, 114. In addition, by the layering of materials in the fixing portion 124, the fixing portion is provided with a width D8 (such as Fig.17 116) so that the securing portion is not pulled through the attachment opening 116 when folded, as would be caused by its attachment to the rod portion 122 when the attached connectors 212, 214 are subjected to tension.

[0103] like Fig.15 As shown, a first layer 134 arranged farthest from the rod portion 122 may be provided. A second layer 138 forming a layer closest to the rod portion 122 may be provided. At least one intermediate layer 136 may further be provided. Fig.15 In the embodiment shown in , an intermediate layer 136 is provided, but it should be appreciated that more than one intermediate layer 136 may be provided. Each layer 134, 136, 138 is preferably formed by folding the material of the stem portion 122 to form the fixing portion 124.

[0104] Preferably, the layers 134, 136, 138 forming the fixing portion 124 are sewn to each other at least around the edges and / or adjacent to and parallel to the first fold 132 using a stitching line 130. The stitching line 130 parallel to the first fold 132 defines the position of the first fold 132 and can therefore preferably be arranged substantially in the middle of the fixing portion 124.

[0105] Peripheral stitching 130a may be provided to secure the edges of each layer of the fixing portion 124 to each other. In addition, a central stitching 130b may be provided to define the location of the first fold 132. The central stitching 130b is parallel to the first fold 132 and extends from the first layer 134 of the fixing portion 124 to the second layer 138 facing the rod portion 122.

[0106] Combination Fig.15 The described sutures 130, 130a, 130b are also applicable to Fig.14 and Fig.16 implementation plan.

[0107] Fig.16 An embodiment of a seat accessory 112, 114 is disclosed, wherein the fixing portion 124 thereof includes a reinforcing element 128. The reinforcing element 128 is formed of a material that is more rigid and has a higher strength than the material of the fixing portion 124. Therefore, the strength of the fixing portion 124 can be improved without having to replace the entire material thereof. Each of the layers 134, 136, 138 of the fixing portion 124 can be made of the same material as the rod portion 122, wherein the rod portion 122 needs to have a certain flexibility to facilitate the movement of the fixing portion 124 during the attachment of the associated connector 112, 124. Therefore, the material of the rod portion 122 and the material of the layers 134, 136, 138 of the fixing portion can be optimized for the properties required of the rod portion 122 (i.e., high tensile strength and flexibility). At the same time, the reinforcing element 128 helps to provide the fixing portion 124 with the desired properties. This further reduces the risk of the seat 200 accidentally falling off the seat accessories 112, 114, while facilitating manufacturing and reducing the manufacturing cost of the seat accessories 112, 114.

[0108] The reinforcing element 128 may be formed of any suitable material having a higher rigidity than the material in the fixing portion 124. Preferably, the reinforcing element 128 is formed of a plastic material. The reinforcing element 128 may be a recycled and / or renewable material, such as a bioplastic. The reinforcing element 128 may be formed of polypropylene (PP) plastic.

[0109] The reinforcing element 128 may have a thickness between 0.5 mm and 2.5 mm, preferably about 1 mm.

[0110] Fig.17 A front detail view of the connectors 212, 214 is disclosed. Fig.17 The connectors 212, 214 shown in FIG. Figure 7 and Figure 8 214. Each connector 212, 214 includes an attachment opening 216. The attachment opening 216 is configured to allow the fixing portion 124 to be inserted therein, so that each connector 212, 214 can be screwed on the corresponding fixing portion 124.

[0111] As mentioned the attachment opening 216 has a width D8, the width direction being defined as the longitudinal direction of the associated webbing 210. The webbing 210 is preferably attached to each connector 212, 214 through a separate opening therein.

[0112] Fig.18 A perspective view of the connectors 212, 214 when attached to the seat accessories 112, 114 is disclosed. When the connectors 212, 214 are subjected to a pulling force from the seat 200 in the direction of the webbing 210, the fixing portions 112, 114 prevent the connectors 212, 214 from being released from the corresponding seat accessories 112, 114 by engaging with the connectors 212, 214.

[0113] In an embodiment, as combined Fig.10 and Fig.11 As described, the connectors 212, 214 and the respective seat accessories 112, 114 may be arranged in a secured state such that during use of the trailer 100, each connector 212, 214 is in contact with or arranged adjacent to the respective seat accessories 112, 114. This reduces the risk of the connectors 212, 214 being inadvertently released from the seat accessories 112, 114, as the distance for relative acceleration / deceleration, which would otherwise allow high impact forces to be generated, is reduced or even eliminated. In the event that there is too much slack in the seat 200, a sudden deceleration of the trailer 100 will give the seat 200 time to decelerate relative to the trailer 100, such that when the connectors 212, 214 come into contact with the seat accessories 112, 114, the forces become too high and there is a risk of the connection between the seat 200 and the trailer 100 becoming disengaged or failing. It will also be appreciated that the secured state may include providing a pre-tensioning force to the seat 200 by increasing the distance D5, as mentioned above.
