Description

Table tennis mount assembly

Technical field

The present invention relates to various parts are connected to table tennis mount assembly on the table tennis table.

Background technology

Table tennis is the motion of a kind of universal indoor/outdoor, and its billiard table that adopts rectangular shape is impacted the celluloid ball of sphere by two to four players and crosses across the net of table center with upright mode tensioning.

Table tennis table has the standard size of 108 inches of length of passing through.Billiard table is typically wide 60 inches from a side to opposite side.Between match and practice period, be provided with center net in the middle of the billiard table, be stretched between the net clamping device that is provided with respectively along both sides.That is, net reaches opposite side from a layback of billiard table.

Routinely, the most universal device that these racks is installed on the billiard table comprises the C clamp pincers.This anchor clamps are detachably fixed on the billiard table by along billiard table side and screw clamp, spring clip or similar means that the bottom surface and the end face of billiard table engage.These anchor clamps are installed in the table center place that table halves crosses and table apron is interrupted.

Yet there are many defectives in this class net installation system.These defectives can be divided into two different classes: (1) net installation system is installed on the billiard table inadequately, uses the net erecting device improperly so that the table top of table tennis table is concordant with (2).

About first problem, in order to use C clamp pincers net erecting device, screw clamp must fully tighten so that rack is installed to securely on the table top of billiard table, and prevents this system moving with respect to billiard table.Yet this erecting device should not installed too firmly simultaneously, if thereby so that when having acted on enough power thereon and moving it, can cause damage to table top.(move and to occur in every way; The situation of frequent appearance is between match period, and the player unexpectedly collides the back or the front of billiard table, perhaps player or this net erecting device of ball impact of being impacted.) at present, still the net erecting device is not fixed to the standard quantification metrics of the power on the billiard table.Therefore, these net erecting devices are not to be exactly exceedingly to be fastened on the billiard table deficiently the most frequently.For arthritic, child or those grip forces are more weak and therefore can not the people of correct by way of expectations fastening C clamp pincers this problem especially exist.If this erecting device is fastened on the table top deficiently, then transverse shearing force will make it move suddenly, and when it moves through regular meeting's table of planing.On the other hand, if this erecting device exceedingly is fastened on the table top, then this way is easy to the bottom surface not only damaging the end face of billiard table but also damage billiard table.Along with little by little aggravation of damage, will be difficult to continue fastening rack.The new regulation that the management table tennis table is made requires to use particieboard/compound pressboard, thereby makes this problem more serious.In case the composite in the net installation region begins to damage, then this damage will be quickened by index law ground with the after-applied uniform pressure relevant with using C clamp pincers net erecting device.

As previously mentioned, using another problem of these C clamp pincers parts is to use these erecting devices to make table " concordant " irrelevantly.The two halves that this way appears at when billiard table are placed into together, and two halves are not concordant each other the time.Opposite with the mode of the adjustment ring of the framework of adjusting billiard table or table leg bottom, many people use C clamp pincers erecting device with the two halves of billiard table be tightened in together up to they be forced to into concordant till.Thereby, lower half uprised and make half higher step-down.Yet, should be clear, the way of this " levelling " unnecessarily makes the billiard table bending near installation site or its, and makes because separation of the time limit, humidity, directed wood drill or the like and " warpage " process on table of Lock-in is quickened.The lasting pressure of C clamp pincers also will make billiard table produce unsuitable strain and fatigue, especially in the net installation region.

For the table top that keeps being fit to, below billiard table, be provided with metallic steel rim or " backplate ".The thickness of steel panel or width can variations, but manyly are essentially 1 inch wide and be connected to the downside of table edge.Backplate extends downwards with the distance between from 1.5 inches to 2 inches usually.This backplate makes billiard table possess the globality of structure by the fulcrum ball edge of table.Thus, backplate helps to prevent that table edge from becoming cracked or damages and to help to postpone the warpage of table corresponding.Because backplate is provided with along each hemisphere edge of table, so it is not continuous along whole billiard table.Thereby, conventional C clamp pincers rack still be clamped to billiard table originally on one's body, rather than on the backplate.Therefore, C clamp pincers parts are installed to traditional method on the table and have destroyed and steel panel is installed to prolong the purpose in table top life-span.

In addition, as the natural result of competing or practice net is used repeatedly, the corner of table end can be owing to fragment, crackle, scratch, breach etc. are out of shape.This is debatable especially because each part of table top surface all belongs to fair play in play.Therefore, any part of bump table comprises that the ball that the quilt in outward flange and corner impacts still belongs to live ball.If strike one of zone of these fragments, crackle, scratch or breach, above-mentioned ball will rebound erratically, thus interruption.

Further explain, increasing, existing for the purpose of competing has again in order to practise the table tennis apparati of purpose except that match rack, racket and billiard table, become the utilizable resource of table tennis player.Part comprises practice net mount, racket fixator, ball fixator, net gauges, decoration key chain and individual scorer etc. in the middle of these apparatuses.These apparatuses are brought facility and relevant area of play into separately by the player usually.Under best situation, these apparatuses use then by its intended purposes that the player removes it from the zone of competing, and normally and not necessarily, the player is forced to leave and put it into sports bag, storage bin or other additional storage zones from table tennis table.In the worst case, between match or practice period, these little article are placed on the floor in match zone with being left in the basket, and at this place, exist significantly and stepped on the great risk that collapses and damage or damage.For large article, for example practice net mount and match rack have formed sizable market and have made and supply the various storage bins that can place these article and carry device.Continue to rely on these outmoded modes that store table tennis apparati will only can hinder the target of the popular attraction of this match of development.

In view of the above problems, will very advantageously design a kind of method, with the net erecting device on being installed to billiard table the time in the mode of damage or crooked court as small as possible, be releasably attached on the table tennis table.When the net erecting device since be subjected to the parallel mobile power of billiard table side backplate accidental backward or when moving forward, it also will provide the bigger resistance of motion.Ideally, this device also will be easy to the installation of net assembly and the dismounting from the billiard table.At last, this device also will provide it will be stored in method on the billiard table itself, and the structural integrity that neither can damage table between match or practice period can not cover table top yet.

Summary of the invention

The invention solves the problems referred to above and realized technological progress.A kind of backplate erecting device is disclosed, its: (1) is suitable for firm and is fixed to needs on the billiard table simply; (2) apply consistent chucking power; And (3) are convenient to easily separate billiard table.Disclose a kind of erecting device similarly, be suitable on billiard table and store other auxiliary table tennis apparati and change, and do not destroyed the structural integrity of billiard table.

With erecting device is fixed on the weakest part of billiard table, it is wood composite billiard table top difference, the present invention is removably mounted on erecting device on the firm and the most stable position of the most close table, i.e. any other metal part of metallic table apron and/or billiard table or billiard table annex.By erecting device is fixed on the metallic table apron, has alleviated when erecting device and to have scratched and the problem of crushing table.And, and may cause the C clamp pincers too early warpage of billiard table, standard different when the incorrect installation inevitably, the present invention does not significantly contact with the wooden part of billiard table, therefore can not cause the billiard table warpage basically.

Importantly, the present invention can also solve better at erecting device between match period and be subjected to pushing away the problem of hitting or how can protect billiard table when mobile.Because existing installation system be fixed on billiard table table top and below, so their easily mobile or " slips " when power is crossed from it.The present invention considers for example center net mount is connected on the backplate in such a way, promptly when having shearing force or push away billiard table or clash into this apparatus accidentally between match period, these power can be passed to the firmest part of billiard table; Backplate.Because this erecting device is fixed on vertical surface (steel panel), rather than on the horizontal surface (table top and following), so power can be distributed on the whole weight of billiard table more equably.

In addition, another problem that relates to storage has also obtained solution.The player can use various table tennis apparati and can remain in the match zone, and needn't place them on the floor after using between match or practice period.In addition, indivedual table tennis clubs can select with large article for example practice net mount or match rack be stored on indivedual billiard tables, thereby make its player can obtain them immediately.Similarly, above-mentioned club these apparatuses can be stored on the metal installing rack with avoid these apparatus mistakes are put or with net material tangle up; If be stored in case or the bucket and these problems can occur usually.

Fashionable when the C clamp cramp joint of the standard of use, as long as be mounted, clamp is just exerted pressure to billiard table.After this manner, the owner of billiard table should be immediately after use removes anchor clamps, is exposed to longways under these pressure avoiding.By apparatus is installed on the apron/frame, the billiard table owner can select these apparatuses are removed, but needn't do like this in order to improve billiard table.Selectively, the player can be fixed to less apparatus on the inner surface of table apron/framework by using magnetic devices, thereby it directly is stored in the below of table.Bigger apparatus can be by similar mode, but perhaps different positions be stored in identical table below.
