PALLET LOCK, LOCK MOUNTING KIT, METHOD FOR MOUNTING A LOCK AND ASSOCIATE PALLET

Description

Technical field to which the invention relates

[0001] The present invention relates to the technical field of pallets and, more particularly, to pallets capable of being surmounted by a belt. Technological background

[0002] Pallets made from synthetic polymers, more commonly known as plastic, are widely used in many industrial sectors for the storage, handling and transport of goods.

[0003] Synthetic polymer pallets offer many advantages over traditional wooden pallets, including durability, lightness, resistance to moisture and corrosion, and ease of cleaning.

[0004] To prevent goods from falling off pallets, it is common practice to secure the pallets with straps, also made of synthetic polymers. A strap consists of one or more panels that run along the sides of the pallet, encircling the goods on it.

[0005] To facilitate the handling and transport of empty pallets, the belt can be composed of several removable walls, so that they can be stacked on the pallet and thus significantly reduce the volume of the pallet.

[0006] To ensure proper support of a belt to a pallet during the transport of goods, the use of locks is known.

[0007] Document EP2783996A1 presents an example of a pallet lock. The lock illustrated on the figure 1The latch, shown below, consists of a latch comprising two bolts 28 and 29, designed to fit into slots provided for this purpose in a belt wall. The bolts 28 and 29 are connected via arms 38 and 40 to a pedal 24. Two spring blades 26 extend from the rear of the pedal 24 and are configured to hold the bolts 28 and 29 in the belt wall when the latch is in the rest or closed position. Thus, an operator can release the belt wall, held by the bolts 28 and 29, by applying pressure to the pedal 24 with their foot. The operator can then use both hands to remove the belt wall without having to bend down, as illustrated in the diagram. figure 7 from document EP2783996A1.

[0008] However, as illustrated by the figure 2The latch 18 proposed in document EP2783996A1 requires the creation of a dedicated space during pallet manufacturing to accommodate the latch and enable its use. Therefore, the latch proposed in this document is not suitable for pallets lacking this dedicated space.

[0009] Other pallet latches are known from US documents 11 577 883 B2 and US 4 936 451 A.

[0010] The present invention aims to provide an alternative pallet latch solution, intended to allow the retention of at least part of a belt on the pallet, integrable into a wider variety of pallets, in particular into pallets not including a housing intended to accommodate a latch. Object of the invention

[0011] To achieve this, the invention proposes a pallet latch comprising a U-shaped spring blade.

[0012] The invention is remarkable in that a first arm of the spring blade is traversed by a passage, so as to allow a foot control, attached to a second arm of the spring blade, to pass through the first arm, and in that the foot control extends sufficiently beyond the first arm to allow an operator to reversibly move a bolt extending from one end of the second arm, towards the first arm.

[0013] Advantageously, the latch proposed by the invention is simpler in design and more compact than the prior art latch described above. Consequently, the latch according to the invention can be more easily integrated into a wider variety of pallets, particularly pallets that do not originally have a designated space for a latch.

[0014] As a non-limiting example, the latch can be integrated or inserted into a first hollow foot of a pallet or into a hollow edge of said pallet.

[0015] The invention thus proposes a latch allowing a belt to be held to a pallet, reversibly, without the need for the pallet to include a specific housing to accommodate the latch.

[0016] In other words, the latch shown above can be integrated into a larger number of pallets compared to the prior art latch described above.

[0017] According to another embodiment of the invention, the second arm of the latch is longer than the first arm, so that the bolt extends beyond the end of the first arm. This embodiment allows both a greater displacement of the bolt at the end of said arm and a freer positioning of the latch within a pallet.

[0018] According to another embodiment of the invention, when the spring blade is at rest, the bolt extends above the end of the first arm. This embodiment allows for better support of the belt wall when the bolt passes through a passage made in said wall.

[0019] According to another embodiment of the invention, the bolt comprises a guide face, configured to allow the arms to spread apart when a wall bears against said guide face. Preferably, the guide face is concave or forms an acute angle with the second arm.

[0020] Preferably, when the spring blade is at rest, the first branch is parallel or substantially parallel to the second branch.

[0021] According to another embodiment of the invention, when the spring blade is under tension, the first branch forms with the second branch an angle whose value is between 10° and 40°, preferably between 15° and 30° or of the order of 20°.

[0022] According to another embodiment of the invention, the first arm has at least one groove on a large outer face of the spring blade. Advantageously, the presence of one or more grooves on the outer face of the first arm of the spring blade allows for more precise retention of the latch against the wall of a pallet and also prevents unwanted pivoting of the latch during use.

[0023] According to another embodiment of the invention, the groove extends parallel or substantially parallel to the second arm. Preferably, at least one groove opens at the junction area connecting the arms of the spring blade, so that it can be used as a guide rail when positioning the latch against a wall equipped with one or more lugs of a shape complementary to said groove.

[0024] According to another embodiment, the first branch includes at least one appendage, of complementary shape to a cavity present on an inner face of a wall of a pallet, so as to prevent the latch from pivoting when it is mounted or integrated into said pallet.

[0025] According to another embodiment of the invention, the sides of the latch arms have notches to facilitate the retention of at least one elastic connecting means between said arms. Advantageously, the elastic connecting means linking the arms allow for a significant and controlled increase in the stiffness of the spring blade, depending on its use and / or the operator.

[0026] By way of non-limiting example, the elastic connecting means may be an elastic band or ribbon, of dimensions adapted to fit easily into the notches on the sides of the latch arms.

[0027] According to another embodiment of the invention, the foot control is a cylindrical or substantially cylindrical appendage extending from the second arm. Advantageously, the free end of the appendage is large enough to allow an operator to move the latch bolt using their foot. Preferably, the appendage extends perpendicularly or substantially perpendicularly to the second arm. The diameter of the appendage at its free end is between 0.5 cm and 6 cm, preferably between 1 cm and 3 cm.

[0028] Of course, the different characteristics, variants and forms of realization mentioned above can be associated with each other, according to various combinations, insofar as they are not incompatible or exclusive of each other.

[0029] The invention also relates to a pallet latch mounting kit, comprising a latch as described above and a clamping plate including at least one appendage extending from said plate, the appendage being able to be inserted through the passage of the first arm of the latch, so as to attach the clamping plate to the latch.

[0030] According to another embodiment of the invention, at least one appendage of the clamping plate includes at least one bolt adapted to bear against an internal face of the spring blade, preferably against the first arm of the latch.

[0031] Advantageously, the mounting kit described above allows a latch to be held firmly to the wall of a pallet, without the need for complex means such as riveting or welding techniques.

[0032] Preferably, the latch and clamping plate are made of the same or similar material as the pallet, so as to allow the pallet to be recycled without having to remove the latch and clamping plate beforehand.

[0033] Preferably, the latch and / or clamping plate are made from one of the following materials: polyethylene, polyoxymethylene, acrylonitrile butadiene styrene or similar.

[0034] The invention also relates to a method of installing a latch according to the invention, using a mounting kit as described above, on a pallet comprising a hollow space, delimited by a wall delimiting one side of the pallet, preferably the wall delimiting a first hollow foot of the pallet, the hollow space is preferably open on the top of the pallet, in order to facilitate the insertion of the latch into the hollow space.

[0035] The process is remarkable in that it implements the following steps: making a hole through the wall, of sufficient dimensions to allow the passage of the control at the foot of the latch; then inserting the latch into the hollow space, so that the end of the control at the foot fits into the passage, and is flush with or protrudes from the wall, and the second arm of the latch is oriented towards the top of the pallet; then inserting at least one appendage of the clamping plate into the hole, so that at least one appendage can bear against a large inner face of the spring blade, preferably against the first arm of the latch, in order to hold the latch against said wall.

[0036] The invention also relates to a pallet for the transport of goods, comprising at least one latch as described above.

[0037] Preferably, the latch is located at the first edge of the pallet, possibly inside a hollow foot of the pallet.

[0038] In one embodiment, the pallet is attached to a belt by at least one retaining means. This retaining means comprises a strap passing through a partition in the belt. The ends of the strap are held to the pallet in such a way as to allow the partition to be tilted over the top of the pallet.

[0039] Preferably, the retaining device is positioned at an edge of the pallet opposite the edge where the latch is located. This embodiment advantageously allows an operator to easily and quickly fold the strapping over the top of the pallet, performing this operation from one side of the pallet, in this case, from the first edge. In other words, this operation is carried out without the operator needing to walk around the pallet to detach each section of the strapping. This is particularly advantageous when only one side of the pallet is accessible to the operator. This might be the case when the pallet is placed against a wall and between two other pallets.

Fig. 11 ] represents a partial view of the palette visible on the figure 9 , when the belt is folded and covers the top of the pallet. Detailed description of the invention

[0041] As a reminder, the invention proposes an alternative pallet latch solution, intended to allow the retention of at least part of a belt on the pallet, integrable into a wider variety of pallets, in particular into pallets not including a housing intended to accommodate a latch.

[0042] THE figures 3 And 4 illustrate a non-limiting embodiment of a latch according to the invention. In this example, the latch 102 consists of a U-shaped spring blade 104. The spring blade is in its rest position on the figures 3 And 4 , corresponding to the closing of the latch.

[0043] The spring blade consists of a first branch 106, which is flat or substantially flat, facing a second branch 108, which is also flat or substantially flat. The branches are connected by an intermediate portion 110, which is rounded or substantially rounded in shape.

[0044] The intermediate portion 110 is configured to keep the branches apart, preferably parallel or substantially parallel to each other, when the spring blade 104 is at rest.

[0045] The smallest distance between branches is between 0 cm and 6 cm, preferably between 1 cm and 3 cm. The branches have the same or nearly the same width, between 2 cm and 10 cm, preferably between 3 cm and 5 cm. The thickness of the branches is between 0 cm and 5 cm, preferably between 0 cm and 1 cm.

[0046] The length of the first branch 106, measured between its free end 112 and the intermediate portion 110, is between 5 cm and 15 cm, preferably between 6 cm and 10 cm. The length of the second branch 108, measured between its free end 114 and the intermediate portion 110, is between 5 cm and 20 cm, preferably between 8 cm and 12 cm.

[0047] It should be noted that in this example, the second branch 108 is longer than the first branch 106, so that a bolt 116 present at the free end 114 of the second branch extends over the free end 112 of the first branch, when the spring blade is at rest or the latch 102 is closed.

[0048] The bolt 116 extends from an inner face 118 of the spring blade, in a direction normal or substantially normal to said face. An upper face 120 of the bolt, opposite the intermediate portion 110, has a contact face 122 inclined or substantially inclined towards the first arm 106, so as to facilitate the spreading of the spring blade 104 when a wall bears against said contact face and exerts a force parallel or substantially parallel to the second arm. In other words, the contact face 122 is designed to allow the arms to spread apart when a wall of a belt bears against said contact face.

[0049] The second arm 108 also supports an appendage 124 extending perpendicularly or substantially perpendicularly from the inner face 118 of the spring blade. The appendage 124 is centered or substantially centered on the second arm.

[0050] According to this example, the appendage is cylindrical or substantially cylindrical in shape, and its length, measured from the inner face 118 of the spring blade, is between 1 cm and 15 cm, preferably between 2 cm and 8 cm. The diameter of the appendage 124 is of a suitable dimension to give it sufficient mechanical strength to act as a control for the foot 126.

[0051] As illustrated by the figure 8 , the operator can then spread apart the arms of the latch 102, by exerting with his foot at the end of the appendage 124, a force sufficient to spread the bolt 116 away from the first arm and thus open the latch 102 to allow the release of a wall previously held by said bolt.

[0052] In other words, appendix 124 is intended to serve as a foot control to operate the latch.

[0053] It should be noted that the shape of the foot control 126 is not limited to this single example of implementation, so the appendage could have any other elongated shape.

[0054] As illustrated by the figure 3 , a passage 128 connects the large faces of the first branch, so as to allow the free end 130 of the appendage 124 to extend beyond the outer face 132 of the spring blade, and thus allow an operator to spread the branches apart.

[0055] According to the present example, at the large faces of the spring blade, the contour 134 of the passage is oblong in shape. The largest dimension of the contour 134 is parallel or substantially parallel to the longitudinal direction of the first branch, so as to allow free movement of the appendage 124 through the first branch 106, when said appendage is actuated by an operator. The largest dimension of the contour 134 is between 1 cm and 10 cm, preferably between 2 cm and 6 cm;

[0056] According to this example, the opening 128 leads into a groove 136 formed in the outer face 132 of the spring blade. More precisely, the groove 136 extends from the opening 128 to the intermediate portion 110 and partially onto said intermediate portion. The depth of the groove 136 is between 0.2 cm and 1 cm, preferably between 0.3 cm and 0.8 cm. Advantageously, the groove 136 is intended to serve as a guide rail when positioning the latch in a pallet and to prevent rotation of the latch when it is held against a wall as explained below.

[0057] According to this example, the sides 138 of the arms connecting their largest faces have notches 140 aligned or substantially aligned in the same plane when the latch is at rest, so as to allow easier retention of at least one elastic connecting means between said arms. The elastic means are not shown in the figures.

[0058] Advantageously, the elastic connecting means linking the arms allows the stiffness of the spring blade 104 to be increased, depending on its use and / or the force applied by the operator. By way of non-limiting example, the elastic connecting means may be an elastic band or ribbon, with dimensions adapted to fit easily into the notches 140 located on the sides 138 of the latch arms.

[0059] Preferably, the latch is a single piece obtained by a molding process. By way of non-limiting examples, the latch may be made from metallic materials or synthetic polymers such as polyethylene, polyoxymethylene, acrylonitrile butadiene styrene, or similar materials.

[0060] To allow for easy and secure attachment of the latch 102 to a pallet, the invention proposes the use of a clamping plate 142 as illustrated by the Figures 5 And 6The clamping plate 142 comprises a rectangular or substantially rectangular plate 144. The plate is delimited by two large faces 146, parallel or substantially parallel to each other. A passage 148 connects the large faces of the plate. The passage 148 is of the same or similar dimensions to the passage 128 passing through the first arm 106 of the latch, so as to allow free movement of the latch arm through the plate 144 when the latch is operated.

[0061] The clamping plate 142 has an application face 150, intended to be in contact with a wall defining an edge or the first leg of a pallet. The application face 150 includes several appendages 152 extending perpendicularly or substantially perpendicularly from said application face. The appendages 152 are aligned or substantially aligned along the contour of the passage 148, so as to allow their insertion through the passage 128 formed in the first arm 106 of the spring blade.

[0062] Each appendage 152 has at its free end a bolt 154 capable of bearing against the inner face 118 of the spring blade 104, when said appendages are inserted into the passage 128 provided through the first branch 106 of the spring blade.

[0063] Of course, the length of the appendages 152 is adapted according to the thickness of the wall of the pallet which is intended to support the latch 102. As a non-limiting example, the length of the appendages 152 is between 0.2 cm and 5 cm, preferably between 1 cm and 3 cm.

[0064] The invention also relates to a method of installing a latch 102 as described above, using a mounting kit, including said latch and the clamping plate 142 presented previously.

[0065] According to the first step of the installation process, a hole 156 visible on the figures 7 And 8 , is made through a first wall 158 delimiting a first edge 159 of the pallet. More precisely, the hole 156 is located at the level of a first foot 160 of the pallet, so as to open into a first housing 161 delimited by said foot.

[0066] Preferably, the first housing 161 is open on the top 164 of the pallet. The first housing is large enough to allow the insertion of the latch 102. If necessary, an opening can be made through the top of the pallet to enlarge or create this first housing 161.

[0067] In a second step, the latch 102 is inserted into the first recess 161 so that the free end 130 of the appendage 124 passes through the hole 156. More precisely, the appendage 124 is inserted into the hole 156 until its free end 130 protrudes from the wall 158, which defines a first edge 159 of the pallet. The latch 102 is oriented in the first recess 161 so that the bolt 116 of the second arm 108 is as close as possible to the top 164 of the pallet.

[0068] According to a third step, the clamping plate 142 is positioned opposite the hole 156, and the appendages 152 of the clamping plate are inserted into the hole 156, until the bolts 154 of the appendages 152 bear against the inner face 118 of the spring blade 104.

[0069] Thus, advantageously, the clamping plate 142 firmly holds the latch 102 in the first foot 160 of the pallet, as illustrated by the figures 7 And 8 .

[0070] Preferably, the outer face 132 of the first arm has a groove, intended to cooperate with at least one appendage present in the first housing, in order to facilitate the insertion and positioning of the latch in the first housing 161. The presence of one or more appendages in the first foot 160 can also prevent the latch from pivoting during use. According to a preferred embodiment, the passage 148 of the clamping plate is elongated, as illustrated by the figure 5 , also to prevent the latch 102 from pivoting in the first foot 160.

[0071] Following the installation procedure described above, the pallet 162 is easily and quickly fitted with a latch 102, securely attached to the first edge 159 of the pallet. Advantageously, the latch is placed in a recess in the pallet not originally designed for this purpose. In other words, the latch can be mounted on pallets that previously did not allow for effective and easy securing of a strap to the pallet.

[0072] As illustrated by the figure 7 The presence of the latch 102 in the first foot 160 advantageously allows for the retention of a first partition 166 of a belt 167 when said partition includes at least one passage 168. The passage 168 is visible on the figure 8 The passage 168 is intended to be occupied by the bolt 116 of the second branch 108, when the latch is in the rest position or in the closed position, illustrated by the figure 7 .

[0073] An operator can then easily release the first partition 166 of the belt, as illustrated by the figure 8 , by applying adequate force with his foot to the end 130 of appendix 124, so as to separate said branches. When the branches are separated, as illustrated by the figure 8 , the bolt 116 of the latch is removed from the first partition 166. The latch 102 is then in the working or open position, the first partition 166 can be lifted in order to detach it from the pallet 162.

[0074] Another advantage is that the presence of the latch inside one of the pallet's feet helps protect the latch from external shocks.

[0075] According to an alternative embodiment illustrated by the figures 9 to 11The pallet 162 described above includes another means 170 for retaining the belt 167. This other means 170 is located at a second edge 172 of the pallet. Preferably, the second edge is opposite the first edge 159 of the pallet. More precisely, this retaining means consists of two passages 174 formed in a second foot 176 of the pallet. This second foot is hollow like the first foot 160, so as to define a second recess 178. The passages 174 are aligned or substantially aligned along the elongation direction of the second foot 176, and the passages pass through a wall of the second foot that is oriented outwards from the pallet.

[0076] The retaining means 170 also includes a strap 180, largely contained within the second housing 178. The strap passes through the openings 174 such that its ends 184 are outside the second foot 176. The ends of the strap are held outside the pallet by suitable means. By way of non-limiting example, the ends of the strap may have extra thickness.

[0077] Advantageously, between its two ends 184, the strap is connected to a second partition 186 of the belt 167 mentioned above. The second partition 168 is opposite the first partition 166 of the belt. To achieve this, according to the present example, the second partition is traversed by a passage 188 through which the strap 180 passes.

[0078] As illustrated by the figure 9The belt 167 is then held to the pallet 162 at another edge. The retaining means 170 thus provides better retention of the belt to the pallet, by holding the belt at two opposite edges of the pallet when the latch 102 is in the closed position.

[0079] Another advantage is that the 170 support means is flexible, allowing an operator, as illustrated by the Figures 10 And 11 , to tilt the second partition 186 onto the top 164 of the pallet, while keeping the second partition attached to the pallet.

[0080] As illustrated by the figure 11 This embodiment advantageously allows the belt 167 to be tied to the pallet when the belt is folded over the pallet, in order to prevent the belt from being lost during the handling of the empty pallet.

[0081] Naturally, the 167 belt is designed to fold easily over the top of the pallet. To achieve this, the 167 belt may have fold lines at the junctions between the partitions, as well as at the intermediate partitions connecting the first and second partitions. Preferably, when the belt is folded, the second partition overlaps the first partition, and the intermediate partitions are positioned between the first and second partitions.

[0082] According to a preferred embodiment, the second foot 176 is located in the middle or substantially in the middle of the second edge 172 of the pallet, in order to allow easier and more precise superimposition of the belt on the top of the pallet.

[0083] Optionally, the pallet may include several retaining devices 170, located at the same edge of the pallet. Preferably, each retaining device is located at one foot of the pallet.

[0084] It should be noted that a pallet 162, as described above, may include one or more retaining means 170, without a latch 102 necessarily being present on the pallet. In other words, the invention may also relate to a belt attached to a pallet by a retaining means as described above.

[0085] However, it should be noted that a pallet equipped with a latch 102 and a retaining means 170 as described above, advantageously allows an operator to easily and quickly fold a pallet strap, by carrying out these operations from only one side of the pallet, in this case from the first edge 159 of the pallet.

[0086] Indeed, the retaining means 170 allows both easy detachment of the belt 167 at the second edge 172, while simultaneously holding the second partition 186 close to the second edge 172 of the pallet. Thus, the operator can easily, and without assistance, use the retaining means 170 to precisely align the folded belt with the top 164 of the pallet.

[0087] In other words, these operations are performed without the operator needing to walk around the pallet to detach each partition from the pallet's strapping, then fold the strapping back down before walking around the pallet again to ensure the folded strapping is properly aligned when it is lying on top of the pallet. This is particularly advantageous when only one side of the pallet is accessible to the operator. This is the case, for example, when the pallet is placed against a wall, between two other pallets.
