The invention relates to an adjustable roping harness, in particular a roping harness that is able to be quickly and easily adjusted for use in collective associations.
In the scope of occasional use for sport activities, and in particular in collective associations, roping harnesses are not used in repetitive manner by only one user. A harness is used by several different users who can present different builds. This configuration can be found in operation of an adventure park, a via ferrata or in an enterprise which supervises groups performing rock climbing on their vacation site. In conventional manner, a set of harnesses is used and is selected as best as possible in order to be able to equip visiting users presenting different builds.
It is particularly complicated to manage a set of non-adjustable harnesses as this means having to be able to provide a large quantity of harnesses in all available sizes to be able to meet the requirements of the different groups. The same is true for very slightly adjustable harnesses which are configured to be very slightly adjusted to a category of users who all present substantially the same build.
Roping harnesses intended for collective organisations and configured to be able to fit people having different builds therefore exist on the market. In order to reduce these stock management limitations, harnesses intended for collective organisations are configured to fit people having different builds in particular as far as pelvis size is concerned. A limited set of harnesses can therefore be adjusted more easily to suit groups of users of different builds.
The Béal company markets a harness under the name of Aero Team IV. The harness has a back foam pad and a strap which form the belt of the harness. The belt operates in conjunction with an adjustment device which is configured to adjust the circumference of the belt by adjusting the length of the strap.
This configuration proves not to be optimal as the harness is designed to be adjusted from XS size to XL size, i.e. for a pelvis with a circumference comprised between 60 cm and 100 cm. Consequently, when the user has a pelvis size of about 60 cm, a length of strap equal to at least 40 cm is left dangling from the belt.
When the user has a pelvis with a circumference of about 100 cm, there is no excess strap, but it can be observed that almost all of the belt is formed by the strap. The lumbar foam pad presents a limited surface so that if the user remains suspended in his harness for a long time, he will suffer a certain discomfort in the whole of the pelvic region.
One object of the invention is to remedy these shortcomings by proposing an adjustable roping harness providing an improved comfort over with the whole range of use and which remains easy to adjust.
For this purpose, the harness comprises:
The harness is remarkable in that:
In one development, the first comfort pad always overlaps the second comfort pad.
In a preferential embodiment, the first comfort pad and second comfort pad are fitted movable with respect to the first strap.
Advantageously, the harness comprises the first comfort pad, the second comfort pad and a third comfort pad. The second comfort pad separates the first comfort pad and the third comfort pad. The first comfort pad and the third comfort pad are fitted in movable manner with respect to the second comfort pad.
In a particular embodiment, the second comfort pad is fixed to the first strap by a fixing part, the third comfort pad being separated from the first comfort pad by the fixing part. The third comfort pad partially covers the second comfort pad.
It is advantageous to provide for the harness to comprise a second blocking stop configured to prevent movement of the third comfort pad with respect to the second comfort pad beyond a threshold value.
In preferential manner, the harness comprises a second adjustment device forming an additional blocking stop.
It is also possible to provide for the first adjustment device to be fixed to a connecting element mechanically connecting the belt to the pair of thigh straps.
In another embodiment, the first comfort pad comprises a first slot for passage of the first strap defined by means of a first edge and the second comfort pad comprises a second slot for passage of the first strap defined by means of a second edge, the first slot and second slot being configured to form the first blocking stop preventing the first edge from passing through the second slot and/or the second edge from passing through the first slot.
In another development, the harness enables the comfort of the adjustable thigh straps to be enhanced.
For this purpose, the harness comprises:
The harness is remarkable in that:
Other advantages and features will become more clearly apparent from the following description of particular embodiments of the invention given for non-restrictive example purposes only and represented in the appended drawings, in which:
Harness 1 comprises a belt 2, a pair of thigh straps 3, and a connecting element 4 which closes belt 2 such as a belay loop or a tie-in loop. Connecting element 4 is mechanically connected to the pair of thigh straps 3. As an alternative, the pair of thigh straps 3 can be fixed directly to belt 2.
Harness 1 also comprises a first adjustment device 5A which is configured to adjust the circumference of belt 2 to the size of the user's pelvis.
Belt 2 is provided with a first strap 6 and with at least first and second foam pads 7 and 8 which are arranged between first strap 6 and the user. Foam pads 7 and 8 are arranged between first strap 6 and the user in order to form comfort areas which prevent direct contact between strap 6 and the user which may result in discomfort points.
First foam pad 7 and second foam pad 8 are fitted movable in translation with respect to one another along the longitudinal axis of first strap 6. First foam pad 7 partially covers second foam pad 8. Foam pads 7 and 8 are fitted movable with respect to one another so that the overlap ratio of first foam pad 7 by second foam pad 8 is modified according to the relative positions of the foam pads to one another.
First foam pad 7 is fitted movable in translation with respect to strap 6 along the longitudinal axis of strap 6. First foam pad 7 can therefore move along the circumference of belt 2 so as to adjust to the user's build and thereby cover first strap 2 as far as possible in order to prevent direct contact between first strap 2 and the user. In advantageous manner, at least 75% of the length of first strap 6 is covered by comfort foam pads. The length of strap 6 covered correspond to the length of strap 6 forming belt 2 and designed to come into contact with the pelvis, i.e. excluding the part of first strap 6 which is situated on the other side of adjustment device 5A.
In particularly advantageous manner, at least 75% of the length of first strap 6 is covered by foam pads when belt 2 defines a minimum circumference. Preferentially, at least 75% of the length of first strap 6 is covered by foam pads when belt 2 defines a maximum circumference.
The belt is advantageously designed to adjust to a pelvis having a circumference comprised between 60 cm and 100 cm, but it is also possible to have a belt able to accommodate a circumference of more than 100 cm.
For example, in the case of a person of slight build, belt 2 defines a small circumference. It is then advantageous to increase the overlap ratio of first foam pad 7 by second foam pad 8. The excess material provided by first foam pad 7 is then located on second foam pad 8 without inconveniencing the user when performing adjustment of the circumference of belt 2 and without creating a bulge of material forming a discomfort point. The fact that first foam pad 7 is overlapped by second foam pad 8 means that two thicknesses of foam padding will be located between the user and first strap 6. For example, the overlap ratio is at least 40% when the belt defines its minimum circumference.
On the contrary, if the person is of larger build, it is necessary to have a belt with a larger circumference. It is then advantageous to stretch first foam pad 7 with respect to second foam pad 8 to increase the surface of first strap 6 which is covered by the foam pads. First strap 6 is thus always mainly covered by a comfort foam pad whatever the circumference used.
It is particularly advantageous to provide for belt 2 to comprise at least a first blocking stop 9 which is configured to prevent movement of first foam pad 7 with respect to second foam pad 8 beyond a threshold value. In other words, blocking stop 9 is configured so that first foam pad 7 always overlaps second foam pad 8 whatever the circumference defined by belt 2. In the embodiment illustrated in
The inventors in fact observed that the use of a non-zero minimum overlap between foam pads 7 and 8 facilitates sliding of first foam pad 7 with respect to second foam pad 8 when adjusting from a large circumference to a small circumference. Adjustment is then facilitated and the user does not have to bother about the placement of foam pads 7 and 8 with respect to one another.
In a particular embodiment, first foam pad 7 is secured to second foam pad 8 by means of a mechanical connector the movement of which is prevented when the overlap ratio of the first foam by the second foam reaches a minimum threshold value. For example, the connector is a strap or a cord one end of which is fixed to first foam pad 7 or to second foam pad 8. The other end collaborates with a clamp respectively fixed to second foam pad 8 or to first foam pad 7 to stop movement of the two foam pads so that the overlap ratio is lower than the minimum threshold value. It is possible to provide for the strap/cord to be fixed at both ends, on the one hand to first foam pad 7 and on the other hand to second foam pad 8, but this leads to formation of bulges and folds when the circumference of the belt is reduced. This embodiment is more complicated to manage as it means that movement of the strap must not be impeded when it folds back.
The inventors observed that sliding of the strap in the clamp until it reaches an end-of-travel stop is easier to achieve and to use. The inventors also observed that it is particularly advantageous to fit the strap and clamp in a sheath in order to protect them and to be able to direct movement of the strap more easily when the circumference of the belt is reduced.
In an embodiment that is not illustrated, first foam pad 7 and second foam pad 8 are both fitted movable with respect to first strap 6. In this configuration, the two foam pads move with respect to one another so as to cover first strap 6 thereby adjusting to the circumference of belt 2. In advantageous manner, covering of first foam pad 7 by second foam pad 8 is at its maximum when belt 2 defines its minimum circumference. It is also advantageous to provide for covering of first foam pad 7 by second foam pad 8 to be at its minimum when the belt reaches its maximum circumference or when belt 2 defines a threshold circumference smaller than the maximum circumference. Beyond the threshold circumference, areas of belt 2 exist that are defined only by first strap 6 which can come into contact with the user. It is advantageous to provide for the areas devoid of covering by first foam pad 7 to be located on the user's abdomen and in contact with adjustment device 5A. The overlap between foam pads 7 and 8 is at its minimum when the foam pads provide maximum covering of first strap 6.
In an embodiment that is not illustrated, first foam pad 7 and second foam pad 8 are both fixed to the at least first adjustment means 5A preferably by means of a flexible part in order to place the ends of first and second foam pads 7 and 8 in immediate proximity to the belt circumference adjustment means according to the circumference of the belt. The flexible part can be loose below a threshold circumference and the tension in the flexible part increases progressively as the circumference increases. The length of the flexible part can be adjusted so that a gear sling 15 fitted on first foam pad 7 and/or on second foam pad 8 is located in the right place on the user's pelvis.
In the embodiment illustrated in
In this configuration, it is particularly advantageous to provide for second foam pad 8 to be mounted fixed on first strap 6 by means of a fixing part 11 which is for example a seam joining first strap 6 to second foam pad 8. It is also advantageous to provide for first foam pad 7 and third foam pad 10 to both be fitted movable along first strap 6.
It is also advantageous to provide for third foam pad 10 to be separated from first foam pad 7 by fixing part 11 along the longitudinal axis of first strap 6. Fixing part 11 advantageously acts as blocking stop for first foam pad 7 and third foam pad 10 in order to define a maximum movement along first strap 6.
The fixing part can also define a maximum overlap ratio for each of first and third foam pads 7 and 10 with respect to second foam pad 8 when belt 2 defines a minimum circumference. As an alternative, the blocking stops of first foam pad 7 and third foam pad 10 can be formed by other parts than fixing part 11.
Fixing part 11 is for example illustrated in
In a particularly advantageous embodiment, belt 2 comprises a second blocking stop which is configured to prevent movement of third foam pad 10 with respect to second foam pad 8 beyond a threshold value. The second blocking stop can define the minimum overlap value between second foam pad 8 and third foam pad 10.
The second blocking stop is advantageously configured so that third foam pad 10 always overlaps on second foam pad 8 whatever the circumference defined by belt 2. In other words, there is always an overlap of third foam pad 10 by second foam pad 8. As previously, this configuration facilitates placing of third and second foam pads 8 and 10 with respect to one another when the user increases the circumference of belt 2 or on the contrary when he reduces the circumference of belt 2. The user does not have to worry about correct placing of third foam pad 10 with respect to second foam pad 8 to prevent formation of bulges which would define discomfort points.
It is particularly advantageous to provide for movement of the first foam pad with respect to the second foam pad to be independent from movement of the third foam pad with respect to the second foam pad.
In the embodiment illustrated in
First and second adjustment devices 5A and 5B are for example formed by first and second metal loops which allow first strap 6 to run freely or on the contrary to be blocked. Each of first and second adjustment devices 5A and 5B forms a blocking stop for maximum elongation respectively of first and third foam pads 7 and 10 when belt 2 defines for example the minimum circumference. These blocking stops correspond to stops defining a minimum overlap ratio of first foam pad 7 on second foam pad 8 and of third foam pad 10 on second foam pad 8.
In the embodiments illustrated in
First blocking stop 9 is advantageously achieved by means of a first slot 13 defined in first foam pad 7 or of a second slot 14 defined in second foam pad 8. Slot 13/14 is a slot enabling first strap 6 to pass through first foam pad 7 or through second foam pad 8. Slot 13/14 defined in first foam pad 7 or in second foam pad 8 is advantageously configured to operate in conjunction with a salient part located on the other foam pad 7 or 8 so as to allow sliding of first foam pad 7 with respect to second foam pad 8 up to a threshold value or until the salient part comes up against the stop formed by the slot. For example purposes as illustrated in
It is particularly advantageous to provide for each of first and second foam pads 7 and 8 to have a slot 13/14 with an edge 13a/14a. The edges are then configured to protrude from the rest of the foam pad and to come into contact with one another to form blocking stop 9 which prevents movement of first foam pad 7 with respect to second foam pad 8 beyond a threshold value. Such an embodiment is illustrated in
This configuration is particularly advantageous as it is simple to achieve and avoids additional parts having to be formed on the circumference of belt 2 as these blocking parts could form points where the harness could catch on elements of the outside environment, for example a branch.
In the embodiment illustrated in
In this embodiment, each thigh strap 3 is formed by at least a first foam pad 7 and a second foam pad 8. First foam pad 7 and second foam pad 8 are fitted movable in translation with respect to one another. At least first foam pad 7 is fitted movable in translation with respect to first strap 6 and first foam pad 7 moves along first strap 6.
What was explained in the foregoing for belt 2 can also be applied here for a thigh strap 3. It is therefore possible to use more than two foam pads 7 and 8. However, the circumference of a thigh being smaller than the circumference of the pelvis, it is particularly advantageous to only use a single first foam pad 7 and a single second foam pad 8.
Depending on the embodiments, first and second foam pads 7 and 8 can both be fitted movable in translation along first strap 6 or it is possible to provide for one of the foam pads to be fixed to first strap 6 by a fixing part 11.
Each thigh strap 3 comprises an adjustment device 5 which is configured to adjust the circumference of thigh strap 3. There again, the circumference of a thigh being substantially smaller than that of the pelvis, it is particularly advantageous to only use a single adjustment device 5.
As for the previous embodiments, it is advantageous to use a blocking stop 9 which is configured to prevent movement of first foam pad 7 with respect to second foam pad 8 beyond a threshold value. In preferential manner, blocking stop 9 is configured so that first foam pad 7 and second foam pad 8 always overlap on one another whatever the circumference of thigh strap 3.
This embodiment is particularly advantageous as it enables the circumference of thigh straps 3 to be adjusted to the circumferences of the user's thighs by taking advantage of first and second movable foam pads 7 and 8 which enable user comfort to be improved when the latter is seated in his harness.
As illustrated in
In the embodiment illustrated in
In a first step represented schematically by the top drawing of
Once the belt has been adjusted to the circumference of the pelvis or approximately adjusted thereto, the user can move first foam pad 7 and third foam pad 10 in order to cover first strap 6 and move the gear slings nearer to more suitable locations. The intermediate drawing of
The bottom drawing of
In this way, placement of the first and third foam pads with respect to the central foam pad enables a substantially symmetric arrangement of the foam pads to be achieved with respect to the sagittal plane of the user.
In the different embodiments illustrated, it is particularly advantageous to provide for second foam pad 8 which is a fixed foam pad to be located between the user and the end of first foam pad 7 and between the user and the end of third foam pad 10. In this way, when belt 2 is tightened, first foam pad 7 and third foam pad 10 can move more freely along first strap 6 without being hampered by contact with the user. However, an opposite configuration is also possible even if it is less practical in use. It is also possible to provide for first foam pad 7 and third foam pad 10 to be separated by second foam pad 8 in a direction which corresponds substantially to the thickness of second foam pad 8.
In the different illustrated embodiments, it is particularly advantageous to provide for first foam pad 7 and third foam pad 10 to each comprise a plurality of slots for passage of first strap 6. This configuration enables the friction existing between first foam pad 7 and strap 6 or between third foam pad 10 and strap 6 to be reduced while at the same time ensuring optimum positioning of first foam pad 7 and third foam pad 10 with respect to the longitudinal axis of strap 6.
It is particularly advantageous to provide for the outer surface of second foam pad 8 which is covered by first strap 6 to be free so as to facilitate sliding of first foam pad 7 with respect to second foam pad 8. This also enables an outside person to check that first and second foam pads 7 and 8 are properly fitted with respect to one another. This configuration is particularly advantageous when the harness comprises a first foam pad 7, a second foam pad 8 and a third foam pad 10.
The embodiment according to
This configuration enables a better adjustment of belt 2 by facilitating placement of second foam pad 8 against the user's back with an independent adjustment of first and third foam pads 7 and 10.
It is particularly advantageous to use a first foam pad which is identical to the third foam pad as far as its shape is concerned but which is oriented differently in order to define a foam pad located on the user's right side and a foam pad located on the user's left side. The two foam pads can have the user's sagittal plane as plane of symmetry.
In an advantageous embodiment comprising first foam pad 7, second foam pad 8 and third foam pad 10, it is advantageous to place a plurality of reference marks on the first and third foam pads. Advantageously the reference marks are identical on the first and third foam pads and are located in such a way as to facilitate placement of the first and third foam pads symmetrically with respect to the user's sagittal plane.
As an alternative, the reference marks can be formed on the first strap. It is also possible to combine this embodiment with the previous embodiment.
In the different exemplary embodiments set out in the foregoing, the harness comprises a plurality of foam pads that are movable with respect to one another. The foam pads represent comfort parts which are configured to distribute the stress imposed by the strap of the belt or of the thigh strap on the user's skin. The foam pad is therefore a pressure distributor and the foam pad can be replaced by or associated with a large number of different materials. It is possible to use gels, textiles and advantageously three-dimensional textiles. It is also possible to use reinforcement parts made from plastic or from other materials which are able to deform to better distribute the stress of the strap. The comfort parts advantageously enable the contact surface with the user to be increased, as they present a larger width than that of the strap. The comfort parts can deform to adjust to the user's build.
