Abstract
The utility model relates to a spiral type blade-shaped rowing plate which is composed of a toughness main plate with size equivalent to the size of a palm and specific weight equivalent to the specific weight of water and block crescent soft molding fin plates which are asymmetrically fixedly arranged on both sides of the main plate. The surface of the main plate is of inwards sloping spiral blade shape, the positions corresponding to a forefinger and a middle finger on the utility model is inwards concave facing water surface, the position little backer than the middle part of the back water side plate surface of the main plate is provided with a circular bulge corresponding to palms, and the back of the main plate is also provided with finger fixing straps and wrist fixing straps. The utility model can help swimming athletes to enhance rowing efficiency and to control reasonable and natural technical operation shape.
Description
The utility model relates to a kind of training device that is used for competitive swimming training, specifically a kind of plate of striking of increasing swimmer's arm load and improving its hand-type technology of being used to, the also applicable aquatic exercise equipment as common swimming fan of this product.
The existing both at home and abroad plate of striking that is used for the competitive swimming training mostly is to be equivalent to toughness (plastics or the light metal) flat board that hand size and proportion is equal to water substantially by one make, and sets up at the back side of plate to be useful on the fixedly fixed band of wrist and finger (or palm).The problem that prior art exists is: since the user wear with this strike during plate must with palm is straight be attached to plate after, the time slightly length can make muscular tone between wrist and finger, if artificial the adjusting firmly can be caused again to move and be out of shape and consumed energy; Simultaneously, this plate of striking also exist make the wearer feel to have into, strike not smooth and the talent for swimming defect of bad.Except that above-mentioned tradition is struck the plate, at present the swimming somebody of circle uses the lobate cambered surface of a kind of similar lotus flower plate of striking, be provided with a boss that adapts with wearer's palm centre of the palm at the rear portion of this backboard face, though wear with having solved to a certain extent behind this plate of the prior artly to go into, the slack problem of striking, but because the position that centre of the palm boss is opened at its back side is afterwards (after the sportsman wears plate, finger is still at regular intervals with the leading edge of plate), the effect of being under pressure of plate face is easy to generate unstability and rocks when trip is advanced, cause the sportsman to strike and embrace in the water transfer process and occur metalling run out, fall phenomenons such as water and stroke sky, reduce the effect of striking; On the other hand, the portion's pressurized of striking in face of the plate is excessive to make the wearer be the shape in the wrong of curling up between palm and finger when firmly trip is advanced toward contact, finalizes the design with regard to greatly having influenced the technology that the sportsman holds water like this.
The purpose of this utility model is the basic theories according to subjects such as hydrodynamics and sport biomechanicses, provide a kind of and can improve the actual effect and make swimmer's rational technique action be able to that naturalization improves and the plate of striking of typing of striking, in order to overcome the many disadvantages of prior art.
For achieving the above object, technical solution of the present utility model is: adopt a kind of profile to meet that swimming exercise is struck in track and the arm cycle firmly and the spiral fan shape plate faces of velocity variations characteristics replace existing tabular plate face or lotus flower foliate lamina face, this plate of striking is equivalent to toughness mainboard and two blocks of asymmetric soft fin keels of moulding of crescent shape that are fixedly arranged on the mainboard both sides that hand size and proportion is equal to water substantially by one and constitutes, the plate face of mainboard is the spiral fan shape of introversion, on it corresponding to the position of forefinger and middle finger to water surface indent, the position is provided with a boss that adapts with the centre of the palm after a while at the middle part of the backwater lateral plates of mainboard, also is provided with finger fixed band and wrist fixed band on the mainboard backboard.After this improves strike the plate template since with swimming exercise in draw, push away, embrace water the technology hand-type have preferably and coincide, thereby the sportsman wear with after sensation pleasant, do not influence force process and normal technical movements, and make them can experience the liter resistance is made a concerted effort when striking variation and effect better.
Below with reference to accompanying drawing the utility model is described further.
Fig. 1 is the profile schematic diagram of this plate of striking (right hand plate).
Fig. 2 sees the shape schematic diagram for overlook (the backwater lateral plates) of this plate of striking (right hand plate).
Fig. 3 is provided in a side of the horizontal sectional schematic diagram of the fingerhold current stabilization bar member at the mainboard back side.
As shown in the figure, this spiral fan shape is struck the outer shape of mainboard 1 of plate like a slice propeller flabellum, the boss 3 that adapts to the palm centre of the palm is located at the position after a while at middle part, mainboard 1 back side, make the position of sportsman's palm lamina affixad will (point roughly concordant) forward like this with the leading edge of plate than the position of crossing the original plate of striking of attachment removal, move on to place, the centre of the palm after so also just making water flow pressure suffered after the plate entry of striking, rock thereby overcome unstability preferably, also can temper athletic forearm strength more targetedly simultaneously.Be provided with two in the place ahead of mainboard 1 backwater lateral plates boss 3 and be nearly straight fusiform clamping current stabilization bar 6, the horizontal section structure of this current stabilization bar 6 as shown in Figure 3, they are by having certain toughness and flexible material is made, its middle part is narrow slightly, slightly expand on top, and the sportsman will point when training and insert and clamp current stabilization bar 6, the effect of existing stationary flow, can strengthen fully coincideing of the centre of the palm and template face again, make the unlikely shape in the wrong of curling up that forms again between palm and finger.Two crescent shape fin keels 2 fixedly are located at the both wings of mainboard 1 asymmetricly by several mainboard reinforcements 8, they are all made by soft-plastic material, setting by fin keel 2 can make the plate of striking that current are had good stable and yielding effect, and the asymmetric also track of striking of identical swimmer's hand-type of form that is provided with of two fin keels 2.For the exterior rim that prevents fin keel in training process might scratch health or other swimmers' health by mistake, can respectively inlay flange 21 one on the outer wing limit of fin keel 2.In addition, good in the water surface in order to help trainer's palm when at a high speed trip is advanced to be in all the time to stablize, edge is provided with fusiform current stabilization bar 7 of being of several projectioies on 1 pair of water lateral plates of mainboard.Label 4 is the finger fixed band in the accompanying drawing; Label 5 is the wrist fixed band.
