Support frame for a respiratory air container

The invention relates to a supporting frame for a breath air tanks, which the torso length of the respective Benut dec is adaptable and a support plate with at this at placed straps and fasteners for minde least a breathing air tank, pneumatic and from the out electrical supply lines for the user hen, comprises.

For stable support of breathing air tanks (SCBA) on the back of that Benut dec, z. B. a fireman, are known of a support plate with risers existing Vorrich tions used.

The support plates are usually one piece and we sentlichen formed in uniform size and in the Shape approximately matching the contour of the back of the people. Of the on the back plate using a mostly Flaschengur tes held breath container is to a at the bottom End of the support plate is mounted reducer concluded from the various supply lines from go and, inter alia, to a manometer and the facepiece a mask worn by the user lead. The Hose lines for compressed air and optionally also electrical leads for warning and measuring devices are fixed to the support plate. Depending on the Kör pergröße of the user takes the support plate at different heights on the back to the plant, namely it ends egg with a little person at the top and at ner tall person in a low-lying area of ​​the Back. Accordingly, this at the front of Be user too large or too small a length of tubing or cable length available, which for too long Hose assemblies of the free and undisturbed movement of User and the observation of the manometer as ent to stand as too short. There is also the risk that do not close to the body lying on the back or free accessible and not visible to the user lie stuck lowing line sections at obstacles or be damaged.

From US 5,020,941 is already a body of Be user to be attached carrying device for a breath air tanks known shoulder interchangeable has parts in different lengths to the Tragege Vice adapt to the body size of the person to. Apart from the fact that in this Lösungsvor beating the corresponding pneumatic and given if electrical leads are exposed, is the ANPAS sung to the body size even with a significant on wall connected.

Furthermore, EP 0747095 A2 a, among other rem also for mounting of breathing air tanks suitable described carrying device, the two-part design is. It consists of an upper back plate and a lower support plate, wherein the lower support plate in egg nem pivot at different heights on the upper Backplate can be mounted. Also in this Tra gege alternate the supply lines are exposed and the pre provided kind of change in length in conjunction with the pivotal suspension of the support plate is a sta bilen holder of breathing air tank to the support plate contrary.

The invention is therefore based on the object to a the height of the user adaptable Tra gege alternate specify for a breathing air container having a stable fixation of the respiratory air container and a ge protected or proximal and ergonomic Anord tion pneumatic or electric supply lines guaranteed.

According to the invention the object is achieved by a supporting frame solved for a breathing air container which, according to the Merkma formed len of claim 1. From the Un dependent claims arise other features and advantageous embodiments of the invention.

The basic idea of ​​the proposed new approach is In other words, the fact that a to the support plate Extension plate slidably and in various Po positions held locked, said on the exten guide plate, the near-shoulder attachment straps of Tra gege stells and the supply lines of Atemluftbe container are attached. Such trained Tote frame may in its length and the length and position of the Supply lines to the torso length of the respective Be be user adjusted so that both a solid Seat of the support frame on the body and on the other hand a secure mounting and tight management of the supply lines is ensured. The supply lines, the lowest in the position of the extension plate, ie, in the smallest form of the support frame, one at the form support plate adjacent reserve loop, be extended when pulling the extension plate quasi and correspondingly shortened during insertion, so that they in each case in the optimum position with respect to the those users are, therefore, neither too long nor are too short and safe handling of these to ensure closed devices. With such from formed carrying frame be user can inde gig of body size despite severe breathing air tank and corresponding supply lines freely and safely move. According to a further feature of the invention is in the extension plate a ver in the longitudinal direction While recording channel for the protected arrangement of Supply lines formed. Advantageously Wei development of the invention is the extension plate over their recording channel in the back of the user out open guiding channel of the support plate out. A Lei tion inlet opening allows the feeding of the United supply lines from the free side of the support plate in the receiving channel of the extension plate. Due to the ses feature, the supply lines, the inde gig by the user only in the shoulder area of ​​the Tragegestell emerge, arranged specially protected.

An exemplary embodiment from which further features, expedient refinements and advantages of the invention result, is illustrated by the drawing. It show:

<b>Fig.</b> 1 shows a view of the back of a user opposite side of an inventive lengths adjustable support frame, with be at this unfortified pressure reduction and connected Supply lines, but without representation the risers and the breathing air container; and

<b>Fig.</b> 2 is a rear view, that is, the back of the User facing side of the support frame after <b>Fig.</b> 1.

The supporting frame <b>1</b> consists of a rigid carrier plate <b>2</b> made of tough plastic with side clips intervened <b>3</b> and first slit openings <b>4</b> for wearing Straps (not shown) and second slot openings <b>5</b> a bottle holding tape (not shown) for BEFE stigung a breathing air container on the back plate <b>2</b>, At the the lower end of the support plate <b>2</b> a pressure reducer <b>6</b> be consolidates at which the to be connected to these Atemluftbe container is also maintained and of the form Reserve a loop a first supply line (Manometer) <b>7</b> a pressure gauge (not illustrated represents), a second supply line <b>8th</b> as Luftversor supply line for the user and a third versor supply line <b>9</b> emanating as a warning line. The tote plate <b>2</b> has been one of the user's back away brought, extending longitudinally, flat U-förmi gen guide channel <b>13</b> on which the lower portion of supporting plate <b>2</b> in a line inlet opening <b>12</b> Upper half of the support plate <b>2</b> formed above Hose guide piece <b>11</b> ends. By Leitungsein exit opening <b>12</b> get the hose lines <b>7</b>. <b>8th</b> and <b>9</b> supplied in the at the back (the back of the user facing side) of the support plate <b>2</b> flat Füh formed signaling channel <b>13</b>, In the guide channel<b>13</b> There is a in this is fitted, essentially U-shaped exten guiding plate <b>14</b>That through guide slots <b>15</b> of leadership cause <b>16</b> in the guide channel <b>13</b> slidably and is guided. The extension plate<b>14</b>, Which at its the top of the slot openings <b>27</b> for attachment of the having near-shoulder carrying belts, is in the Führungska nal <b>13</b> the support plate <b>2</b> locking in four detent positions bear. For this purpose, at the opposite Be tenwände the guide channel <b>13</b> pairs gegenüberlie lowing locking grooves <b>17</b>. <b>18</b>. <b>19</b> and <b>20</b> formed in which at the extension plate <b>14</b> with the aid of a spring element <b>20</b> in a guide groove <b>21</b> elastically held locking handle pieces <b>22</b> can be latched. With the help of in ver different locking positions (locking grooves <b>17-20</b>) lockable extension plate <b>14</b> can thus supporting frames <b>1</b> in different, the height (or torso length) of User matched length are provided. In the embodiment, there are the locking handle pieces <b>22</b> in the locking grooves <b>19</b>So that the Darge presented Tragegestell <b>1</b> nor extended or shortened who the can.

The Arretiergriffstücke <b>22</b> are as large volume, to formed upwardly open trays, which thus, even if the Users gloves wearing, easy to handle are. The extension plate<b>14</b> has at its two Longitudinal edges a respective outwardly facing rim <b>14</b>Å. The edge strips<b>14</b>a cover locking grooves <b>17</b> to <b>20</b> on the side walls of the guide channel <b>13</b> the support plate <b>2</b> upwards and at the same time form a plane Contact surface on the back of the user. At the lower edge the extension plate <b>14</b> are inwardly clamping grooves <b>23</b> provided, in which the in <b>Fig.</b> 1 Darge easily supply lines <b>7</b> to <b>9</b> clamped and there are held firmly. The supply lines<b>7</b> to <b>9</b> are in an on the inside (the back of the user facing side) of the extension plate <b>14</b> divided by two longitudinal webs <b>24</b> limited receiving channel <b>25</b> out and ge long through a line exit aperture <b>26</b> in the United length guide plate <b>14</b> between the third Schlitzöffnun gene <b>27</b> outward.
